Description

The present invention relates to a conveying device and a method for connecting a conveying device.

Transportation devices are known for transporting materials and equipment at construction sites, etc.

For example, a method is known for transporting materials and equipment using so-called containers. Specifically, the container is first stored in a folded state. Then, when the materials and equipment are to be transported, the container is assembled. Once the container is assembled in this way, the materials and equipment can be stored in the container. Therefore, a method is known for transporting materials and equipment by assembling the container, storing the materials and equipment, and then moving the container that stores the materials and equipment (for example, Non-Patent Document 1, etc.).

There is also a known method of transporting materials and equipment using an AGV (Automated Guided Vehicle). Specifically, a method is known in which materials and equipment are automatically transported horizontally by an AGV having a horizontal transport means for loading and unloading the materials and equipment, thereby improving labor productivity (see, for example, Patent Document 1, etc.).

In addition, forklifts, lifting lifts, etc. may be used to transport materials and equipment to work areas or stockyards at construction sites. Using forklifts, lifting lifts, etc., materials and equipment can be transported to multiple floors. Thus, a method is known in which materials and equipment are automatically transported to a location where predetermined work is to be performed using a forklift, lifting lift, etc. (for example, Patent Document 2, etc.).

Asahi Kizai Co., Ltd., "E-Container", [online], September 2011, [Retrieved November 19, 2019], Internet <URL: http://www.asahikizai.com/wp-content/uploads/2018/10/e_container_okyaku.pdf>

However, conventional conveying devices often cannot be used as so-called scaffolding. In other words, workers often cannot stand on the conveying device and perform work on high places such as ceilings.

The present invention was made in consideration of the above problems, and aims to provide a transport device that workers can ride on.

The transport device and the method for connecting the transport device according to each embodiment of the present invention are configured, for example, as follows.

A transport device for transporting materials and equipment (for example, the transport device 100 shown in FIG. 1)
A side portion (e.g., a side plate PT shown in FIG. 18 ) that forms a space for storing the materials and equipment (e.g., the space SP shown in FIG. 1 ),
A ceiling portion (e.g., a ceiling CE shown in FIG. 18 ) that is perpendicular to the side portion and forms a ceiling of the space,
The side surface portion is movable in a height direction,
When the side portion moves upward in the height direction, it becomes a handrail (for example, the handrail HR shown in FIG. 21 ) when a worker boards the ceiling portion to work.
Or,
When the side portion moves upward in the height direction, rotates, and connects to another conveying device, it becomes a scaffold (for example, the side panel PT shown in Figure 20) for the worker to board and work on.

With this configuration, it is possible to create a transport device that can accommodate a worker, as shown in Figure 21, for example.

In addition, the side surface portion is
The portion in contact with another transport device is partly or entirely made thinner (such as the connecting portion CN shown in FIG. 22 or a connecting portion using a tip portion shaped as shown in FIG. 29).

In particular, the side portion is
It has an L-shape that becomes thinner partly or entirely toward the other conveying device (such as the tip portion PTL shown in FIG. 22).

In addition, the tip of the side surface portion and the ceiling portion of the other conveying device are connected to each other at a contact point,
The tip portion has a shape in which a part or the whole of the tip portion is thinned (for example, a tip portion having a shape as shown in FIG. 29 is used and connected as shown in FIG. 30, etc.).

In this way, a thinner shape can reduce the step.

In addition, a conveying device for conveying materials and equipment (for example, the conveying device 100 shown in FIG. 1)
A side portion (e.g., a side plate PT shown in FIG. 23 ) that forms a space for storing the materials and equipment (e.g., the space SP shown in FIG. 1 ),
A ceiling portion (e.g., a ceiling CE shown in FIG. 18 ) that is perpendicular to the side portion and forms a ceiling of the space,
The side surface portion is
It is connected to other conveying devices at either a first height (for example, the first height H1 shown in FIG. 23) or a second height lower than the first height (for example, the second height H2 shown in FIG. 23), and serves as a scaffold for workers to board and work on (for example, either FIG. 21 or FIG. 25).

With this configuration, it is possible to create a transport device on which a worker can ride, as shown in Figure 21 or Figure 25, for example.

The side portion can be slid to switch between the first height and the second height (for example, from the first height H1 to the second height H2 shown in FIG. 23).

With this configuration, it is possible to create a transport device on which a worker can ride, as shown in Figure 21 or Figure 25, for example.

In addition, at least one side in the horizontal direction or in the depth direction (for example, the side in the X-axis direction or the Y-axis direction shown in FIG. 28) has a dimension of 1060 mm or less. In this way, if the conveying device 100 is small, multiple conveying devices 100 can be mounted on a truck or the like.

In addition, the side surface portion is
The side portion is movable in the height direction, and when the side portion moves upward in the height direction, it becomes a handrail when a worker boards the ceiling portion to work (for example, the handrail HR shown in Figure 2 (A)).

With the above configuration, the transport device 100 has a ceiling so that workers can stand on it. In this way, the transport device 100 is configured to transport materials and equipment to a work location and to be used as a scaffold at the work location.

It is also desirable that when the side portion moves upward in the height direction, an opening (such as the opening OP shown in FIG. 2(A)) is formed in the space.

With the above configuration, it is possible to remove pre-installed equipment and materials from the opening OP, or store the equipment and materials in the space SP.

In addition, when the side surface portion moves upward in the height direction,
It is desirable that the handrail be configured to be 900 mm or more high from the ceiling (for example, as shown in FIG. 2(A)).

With the above configuration, the conveying device 100 meets the requirements set forth in occupational safety and health regulations, etc., and can prevent workers MN, etc. from falling.

In addition, the ceiling portion is
A configuration in which the height from the floor surface is less than 2000 mm and is greater than or equal to 1500 mm (for example, the height of the conveying device 100 in the Z-axis direction shown in FIG. 1A) is desirable.

With the above configuration, the transport device 100 can be used as a scaffold for work at height and can be easily installed.

It is also preferable that the conveying device 100 further includes an auxiliary plate that closes any gaps that may occur at the boundary between the side portion and another side portion.

With the above configuration, the conveying device 100 can prevent accidents such as tripping.

The method for connecting the transport device is as follows:
A side portion that forms a space for storing materials and equipment;
a ceiling portion that is perpendicular to the side portion and forms a ceiling of the space,
A step of moving the side portion upward in the height direction to install a handrail when a worker climbs onto the ceiling portion to work; or
The side surface portion is
This includes any of the procedures for connecting the device to another transport device and forming a scaffold for the worker to board and work on (for example, a connecting method as shown in Figure 17).

By using the above connection method, the transport device can be turned into a scaffold on which workers can stand.

The method of connecting the transport device is as follows:
A side portion that forms a space for storing materials and equipment;
a ceiling portion that is perpendicular to the side portion and forms a ceiling of the space,
a determination step of determining a height at which the conveying device is connected to another conveying device, the height being either a first height or a second height lower than the first height;
The method includes a step of connecting the side portion to another conveying device at either the first height or the second height selected in the judgment step, and forming a scaffold for workers to board and work on (for example, a connecting method as shown in Figure 27).

By using the above connection method, the transport device can be turned into a scaffold on which workers can stand.

Each embodiment of the present invention provides a transport device that can accommodate workers.

The following description will focus on the optimal and minimal form for implementing the invention, and will refer to the drawings. Note that when the same reference numerals are used in the drawings, they indicate similar configurations, and duplicated explanations will be omitted. Also, the specific examples shown in the drawings are merely examples, and the configuration may further include configurations other than those shown in the drawings.

First Embodiment
<Configuration example of conveying device>
1 is a diagram showing an example of a conveying device. Hereinafter, the conveying direction in which materials and equipment are conveyed by the conveying device 100 will be referred to as the "Y-axis direction." The direction perpendicular to the Y-axis will be referred to as the "X-axis direction." Therefore, the XY plane is a plane parallel to the floor surface GD. Furthermore, the height direction will be referred to as the "Z-axis direction."

Figure 1(A) is a side view, Figure 1(B) is a front view, and Figure 1(C) is a plan view.

As shown in the figure, the conveying device 100 has a length of 4,200 millimeters in the Y-axis direction. The conveying device 100 has a height of 1,950 millimeters in the Z-axis direction. The conveying device 100 has a width of 900 millimeters in the X-axis direction.

Equipment and materials include tools used in work at a construction site, components and materials installed in a building, and accessories associated with these. For example, components installed in a building include pipes, ducts, air conditioners, and fans installed in the ceiling of the building, as well as hanging fixtures for installing these on the ceiling.

As shown in FIG. 1(A), the conveying device 100 is configured to include a mesh ME, which is an example of a side portion. Specifically, the mesh ME is a plate material or the like that is installed in the Y-axis direction. The illustrated example is an example in which four mesh MEs are installed in the Y-axis direction. Furthermore, the illustrated example is an example in which a mesh ME is also installed in the X-axis direction, i.e., at a position that is the front side. In this way, multiple mesh MEs are installed on the side surfaces.

As shown in FIG. 1(C), the conveying device 100 has a ceiling plate PL, which is an example of a ceiling portion, in a direction perpendicular to the side portion (on the X-Y plane in the figure). In other words, the ceiling plate PL is a plate that forms the ceiling of the conveying device 100.

As shown in the figure, the materials and equipment are stored in the inner space SP surrounded by the ceiling plate PL and the mesh ME. Therefore, after the materials and equipment are stored in the space SP, the materials and equipment can be transported by moving the transport device 100.

After storing the materials and equipment, the transport device 100 is transported in the manner shown in the figure. After being transported, the transport device 100 is set, for example, as follows.

Figure 2 is a diagram showing an example of a case where the side portion is moved upward in the height direction. Compared to Figure 1, Figure 2 differs in that one of the four mesh MEs is moved upward in the Z-axis direction.

In this way, the mesh ME is a mechanism that can move up and down in the Z-axis direction. Specifically, the mesh ME is a mechanism that slides in the Z-axis direction. Furthermore, the mesh ME is a mechanism that can be moved upward and then fixed in the position after movement.

In the state shown in FIG. 2, the mesh ME has moved upward, forming an opening OP. Therefore, it is possible to remove pre-installed equipment and materials from the opening OP, or to store equipment and materials in the space SP.

In addition, by moving the mesh ME upward, the mesh ME becomes a handrail HR. Specifically, as shown in FIG. 2(A), the mesh ME moves upward when a worker MN uses the conveying device 100 as a scaffold (which, in the Industrial Safety and Health Regulations, is referred to as an "erecting passage," "scaffold," "work floor," or "steel pipe scaffold," etc.; hereafter simply referred to as "scaffold") at a position where work is performed on a high place such as a ceiling (the so-called work location. The work location is assumed to be determined in advance by a plan, etc.), and the worker MN uses the conveying device 100 as a scaffold.

This allows materials and equipment to be transported to the work site.

Furthermore, at the work site, the transport device 100 can be used as a scaffold. The mesh ME acts as a handrail HR (in FIG. 2(A), if the other mesh MEs are also moved upward, they can surround the ceiling), preventing the worker MN from falling.

In this way, the transport device 100 has a ceiling so that workers can ride on it, and it is configured to transport materials and equipment to a work site and also to be used as a scaffold at the work site.

Therefore, by using the transport device 100, the work area and the storage area for equipment and materials (hereinafter simply referred to as the "storage area") can be arranged without being separated.

Traditionally, materials and equipment are stored in storage areas, so scaffolding cannot be installed in storage areas. As a result, when a storage area is used, the materials and equipment must be transported to another location before scaffolding can be installed and the area can be used as a work area. This often results in poor work efficiency.

On the other hand, since the transport device 100 can store materials and equipment, the location where the transport device 100 is located can be used as a storage area. Furthermore, since the transport device 100 can also be used as scaffolding, the location where the transport device 100 is located can also be used as a work location. Therefore, the location of the transport device 100 can serve as both a storage area and a work location. This reduces the amount of work required to transport materials and equipment to another location in order to set up scaffolding, improving work efficiency.

<Modification>
The conveying device 100 may have the following configuration.

The mesh ME may be of any shape that prevents stored materials and equipment from falling during transport, for example, a mesh-like material.

The mesh ME may be movable in a manner other than sliding. For example, the mesh ME may be moved from a state in which it is positioned downward on the Z axis (such as the state shown in FIG. 1), with the upper end of the mesh ME as the axis of rotation (rotation around the Y axis, which is a so-called pitch rotation method).

In addition, the mesh ME may have a mechanism that allows it to be removed from and attached to the conveying device 100. Specifically, the mechanism may allow the mesh ME to be attached in a lifted state after being removed from the state shown in FIG. 1, so that the mesh ME is in the state shown in FIG. 2.

The side portion is not limited to mesh ME. In other words, the side portion may be any material that can form a space for storing materials and equipment and that can serve as a handrail when moved upward in the height direction. Therefore, the side portion may be a plate material, a rod material, or a combination of these, etc.

The number of mesh MEs does not have to be four. That is, the side portion may be made up of four or more mesh MEs, or less than four mesh MEs. Furthermore, the side portion may be an object made up of two or more mesh MEs combined into one. That is, two or more mesh MEs may be connected together, allowing multiple mesh MEs to be opened and closed with a single opening and closing.

The mesh ME may or may not be installed on what would otherwise be the front and rear surfaces.

In the above example, the longitudinal direction is used as the transport direction, but the longitudinal direction does not always have to be the transport direction. In other words, the transport device 100 may transport in a direction other than the longitudinal direction.

The ceiling plate PL may be a single plate material or a combination of multiple plate materials.

It is desirable that the transport device 100 be configured to meet the Temporary Equipment Certification Standards (hereinafter simply referred to as "Temporary Equipment Certification Standards") established by the Temporary Construction Industry Association. Specifically, to be used as scaffolding at construction sites, etc., mobile indoor scaffolding, elevated work platforms, or portable aluminum alloy work platforms must meet the requirements set forth in the Temporary Equipment Certification Standards to ensure safety.

In other words, conventional containers and the like often cannot be used as scaffolding at construction sites, etc. On the other hand, if the transport device 100 meets the temporary equipment certification standards, it can transport materials and equipment at construction sites, etc., and can also be used as scaffolding.

Similarly, it is desirable that the ceiling be constructed in a way that satisfies the standards for metal scaffolding boards or beams, etc., as specified in the Temporary Equipment Certification Standards.

Furthermore, it is desirable that the handrail HR be configured to meet the standards for the certification of temporary equipment, such as a leading handrail for wedge-fastened scaffolding, a handrail frame for framed scaffolding, a handrail and middle rail for wedge-type scaffolding, or a handrail frame for staircase openings.

If the structure meets the above-mentioned certification standards for temporary equipment, it will be compatible with the materials and fittings for steel pipe scaffolding stipulated in Article 42 of the Industrial Safety and Health Act, Article 13 of the Enforcement Order of the Industrial Safety and Health Act, and Appendix 8 of the Enforcement Order of the Industrial Safety and Health Act, and therefore can be installed at construction sites, etc.

Therefore, it is desirable that the materials and structure of the ceiling meet the requirements for materials, standards, qualities, wall thickness, structure, dimensions, etc., stipulated in Part 2, Chapter 10, Section 2, Articles 559 to 563 and Articles 570 to 573 of the Industrial Safety and Health Regulations.

It is also desirable for the handrail HR to be at least 850 mm high from the ceiling, such as 900 mm in the example of Figure 2 (A). A handrail HR of this height will satisfy Part 2, Chapter 10, Section 2, Article 552, Paragraph 1, Item 4 (a) of the Industrial Safety and Health Regulations.

In this way, the conveying device 100 can prevent the worker MN from falling by using the handrail HR.

It is desirable that the height of the conveying device 100 from the floor surface GD be "less than 2000 millimeters." In order to assemble a scaffolding structure with a height of "2 meters or more," it may be necessary to take measures, for example, pursuant to Article 564 of Part 2, Chapter 10, Section 2 of the Industrial Safety and Health Regulations. Therefore, if the height of the conveying device 100 from the floor surface GD is "less than 2000 millimeters," installation etc. will be easier. On the other hand, it is desirable that the conveying device 100 has a certain degree of height as a scaffolding in order to work on high places such as ceilings. Therefore, it is desirable that the height of the conveying device 100 from the floor surface GD be "1500 millimeters or more."

Thus, with a height of 1,500 mm or more and less than 2,000 mm, the conveying device 100 can be used as a scaffold when working at high altitudes and can be easily installed.

In addition, it is desirable for the conveying device 100 to have a length of "4000 millimeters or more" in the conveying direction, such as "4200 millimeters" shown in FIG. 1 (A). For example, at construction sites, fixed-length materials such as beams or girders are "4 meters," "5 meters," "6 meters," etc. Therefore, it is desirable for the conveying device 100 to have a length of "4000 millimeters or more" so that fixed-length materials can be stored. In addition, it is desirable for the space SP of the conveying device 100 to have a certain amount of leeway in length in order to store fixed-length materials. Therefore, if the conveying device 100 has a length such as "4200 millimeters," it will be able to store fixed-length materials.

Furthermore, it is preferable that the conveying device 100 has a width in the orthogonal direction of "900 mm" to "1000 mm", such as "900 mm" shown in Figure 1 (B).

The conveying device 100 is often transported to construction sites and the like by truck or the like. The width of the truck bed is often about 2 meters. Therefore, if the width of the conveying device 100 is 900 to 1000 millimeters, it is easy to load multiple units onto the bed of a truck or the like.

It is also preferable that the transport device 100 further includes a ladder LA that assists in boarding to the ceiling. For example, the transport device 100 has the following configuration.

Figure 3 shows an example of a transport device equipped with a ladder. Below, we will explain using a side view of the transport device 100 (similar to Figure 1(A) and others).

As shown in the figure, the conveying device 100 is provided with a ladder LA, for example, on the side. In this manner, the ladder LA makes it easier for the worker MN to climb onto the ceiling.

The conveying device 100 is often at a height of about 2000 mm to perform work on high places such as ceilings. Therefore, it is difficult for the worker MN to get on to the ceiling unless there is equipment to assist with getting on, such as a ladder LA.

As shown in the figure, a configuration including a ladder LA makes it easy for the worker MN to board the ceiling. In particular, if the ladder LA is integrated, the work of setting up the ladder LA can be reduced, making the work more efficient. However, the ladder LA may be configured to be retrofitted.

The shape, installation position, and number of ladders LA are not limited to those shown in the figure. In other words, ladders LA may be installed on the front or back surface, etc., other than the side surface. Also, multiple ladders LA may be installed.

For example, if the ladder LA is installed at a position such as the front (the surface shown in FIG. 1(B)) or rear, the conveying device 100 is less likely to tip over even if a moment is generated near the ladder LA based on the weight of the worker MN when the worker MN uses the ladder LA to get on or off the ceiling. Therefore, it is preferable to install the ladder LA on the short side, such as the front or rear.

The conveying device 100 is preferably used in combination with an operating device, for example, as follows:

Figure 4 is a diagram showing an example of using an operating device. For example, it is desirable that the conveying device 100 is moved to a predetermined position by an AGV (Automated Guided Vehicle, hereinafter referred to as "AGV101"), which is an example of an operating device. In this way, a conveying system having the AGV101, which is an example of an operating device, and the conveying device 100 may be configured. The conveying system may further have one or more information processing devices. For example, in the conveying system, the AGV101 and the information processing device are connected via a network. Specifically, the conveying system may use an information processing system 10, a server 11, an information processing terminal, or a combination of these, as shown in Figure 8, which will be described later.

With this configuration, it is possible to provide a transport device that can accommodate a worker MN, and the transport device 100 can be automatically transported after work is completed, such as at night.

The AGV 101 is a hardware configuration that includes an actuator for moving the transport device 100, a sensor for measuring the current position of the AGV 101, a communication device for communicating with other external devices, an interface for inputting the destination, etc., a power source, and a control device for controlling each piece of hardware.

The AGV 101 is not limited to the hardware configuration described above. That is, the AGV 101 may be any device capable of moving the transport device 100. The AGV 101 does not have to be a single device. That is, the AGV 101 may be a device in which multiple devices move a single transport device 100, or the AGV 101 may be configured to connect information processing devices internally or externally.

For example, the AGV 101 moves the transport device 100 as follows:

Figure 5 is a diagram showing an example in which the operating device moves the transport device. In the following, it is assumed that the transport device 100 is placed at the initial position P1. The installation position P2 is input in advance to the AGV 101. In the following, an example will be explained in which the initial position P1 is the "first floor" and the installation position P2 is the "second floor", and the initial position P1 and the installation position P2 are on different floors.

In this example, the AGV 101 first moves the transport device 100 from the initial position P1 to the elevator EV. Then, the elevator EV lifts the transport device 100 from the "first floor" to the "second floor." Then, after being lifted to the "second floor" by the elevator EV, the AGV 101 moves the transport device 100 to the installation position P2.

In this way, when the transport device 100 is installed at a predetermined position by the AGV 101, the transport device 100 can be installed at a work site, for example, during the night when no work is being performed. Therefore, the workload of installing the transport device 100 can be reduced.

It is also preferable that the AGV 101 can be an elevator EV or the like. In this way, if the transport device 100 can be moved using an elevator EV or the like, the AGV 101 can be shared among multiple floors without installing an AGV 101 on each floor. In other words, the number of AGVs 101 can be reduced.

It is also desirable that the transport device 100 and the AGV 101 can be separated as follows.

Figure 6 is a diagram showing an example of separation of a transport device and an operating device. For example, after the transport device 100 is installed at installation position P2, it is desirable to separate the AGV 101 from the transport device 100 as shown in the figure. In this way, when the transport device 100 and the AGV 101 can be separated, the AGV 101 can also move other transport devices 100.

On the other hand, the conveying device 100 may be a hardware configuration including sensors, communication devices, interfaces, and control devices. In other words, the conveying device 100 may have the functionality of an AGV. The conveying device 100 may be configured to self-propel based on the control of a control device by driving the wheels of the conveying device 100 with actuators using the functionality of an AGV.

Using such an AGV 101, the transport device 100 can be installed, for example, as follows:

Figure 7 is a diagram showing an example of automatic transportation. In this example, first, the transport device 100 is transported to the construction site by the truck 21. After that, the transport device 100 is unloaded from the truck 21 by the forklift 20. Next, the transport device 100 is placed near the elevator EV by the forklift 20. This position becomes the initial position P1 in Figure 5. That is, when the AGV 101 is prepared in advance at the initial position P1, the transport device 100 is lifted from the initial position P1 to another floor by the AGV 101 and the elevator EV as shown in Figure 5. Then, after the transport device 100 and the AGV 101 are lifted by the elevator EV to the floor of the installation position P2, the transport device 100 is moved to the position of the installation position P2.

In this way, it is desirable for the conveying device 100 to automatically convey the objects. However, instead of conveying the objects entirely automatically, as in this example, some of the conveying may be done by a forklift 20 or a worker MN, etc.

When performing the above-described automatic transport, for example, an information processing system such as the following may be used.

Figure 8 shows an example of management by an information processing system.

By using BIM (Building Information Modeling) data to match 3D CAD data with the design information or attribute information of each model, the information processing system 10 can determine which floor it is from several models. In addition, the name of the area, etc. can be read from the attribute information, etc. and displayed.

Therefore, when the drawing data input procedure is performed, the information processing system 10 displays the drawing. Specifically, the information processing system 10 can show the building in a drawing and display fixed beacons, mobile beacons, etc. in correspondence with the drawing.

The information processing system 10 manages the transport device 100 and the like. That is, the information processing system 10 maps the transport device 100 and controls its movement to the installation position P2, etc.

For example, the information processing system 10 has information processing devices such as a server 11, a first information processing terminal 102, and a second information processing terminal 103. Furthermore, the server 11, the first information processing terminal 102, and the second information processing terminal 103 are connected by wire or wirelessly, and are capable of transmitting and receiving data to and from each other. Therefore, in the information processing system 10, the processing results by the server 11 are output to the first information processing terminal 102, the second information processing terminal 103, etc., and the processing results can be viewed at each base or field office, etc. Furthermore, by inputting operations at the first information processing terminal 102, the second information processing terminal 103, etc., the server 11 can accept the operations.

Note that the information processing system 10 is not limited to the configuration shown in the figure. In other words, the information processing system 10 may have one information processing device, or two or more information processing devices. The following description will be given using the configuration shown in the figure as an example.

First, at the construction site, a transmitter that transmits a beacon signal is installed on the transport device 100. Furthermore, transmitters are also installed on pillars and the like at the construction site. Hereinafter, the transmitter installed on the transport device 100 may be referred to as the "mobile beacon 121." When the transport device 100 moves, the mobile beacon 121 moves with it, and so its position changes. In other words, the mobile beacon 121 is a sensor and communication device that notifies the current position of the transport device 100. Hereinafter, the position of the mobile beacon 121 is assumed to be the same as the position of the transport device 100.

On the other hand, transmitters are installed on pillars or the like at the construction site, and in principle, their positions are fixed. Hereinafter, transmitters installed on pillars or the like at the construction site may be referred to as "fixed beacons 122." Therefore, the position of the fixed beacons 122 is fixed at the position that is installed in advance.

In addition, in this example, at the construction site, it is assumed that on-site worker 201 and on-site worker 202 have mobile terminals 104 such as smartphones, tablets, or notebook PCs (Personal Computers). Hereinafter, it is assumed that mobile terminals 104 are receivers that receive signals from each transmitter. Then, the receivers transmit the contents indicated by the signals from each transmitter, i.e., data that can identify the respective positions of each transmitter (hereinafter referred to as "positioning data"), to information processing system 10. Note that the timing at which the various data are transmitted may be at preset intervals or may be irregular.

With such positioning data, the AGV 101 can ascertain its current position, etc. Therefore, by using map data of the construction site, the AGV 101 can ascertain how to move the transport device 100 from the difference between its current position and the installation position P2.

In addition, the information processing system 10 may be configured to include information processing devices and sensors other than those shown in the figure.

The conveying device 100 may also be connected for use, for example, as follows:

Figure 9 is a diagram showing a first example of connecting multiple transport devices. First, as shown in Figure 9 (A), assume that two or more transport devices 100 are installed at installation position P2 by an AGV 101 or the like.

As shown in FIG. 9(B), for example, multiple conveying devices 100 may be connected together using a connecting plate 300, which is an example of a connecting portion.

It is desirable that the connecting plate 300 is configured to be movable so that it can be stored in the transport device 100, as shown in FIG. 9(B). It is also desirable that the connecting plate 300 is configured so that when the transport device 100 is connected, as shown in FIG. 9(B), a worker MN can ride on the connecting plate 300. In this way, if the transport device 100 can be connected and used, high places such as ceilings can be widely used as work targets.

The conveying device 100 may be used by connecting three or more conveying devices 100 together using the connecting plate 300, for example, as follows:

Figure 10 is a diagram showing a second example of connecting multiple conveying devices. The example shown is an example in which two conveying devices 100 connected as shown in Figure 9 (B) are combined into one set, and three sets are connected in the Y-axis direction (the longitudinal direction of the conveying devices 100 in the figure).

In addition, two or more sets of conveying devices 100 may be connected. Furthermore, the connection direction is not limited to the Y-axis direction, and may be the X-axis direction.

Alternatively, the transport device 100 may be connected as follows:

Figure 11 is a diagram showing a third example of connecting multiple transport devices. For example, as shown in Figure 11 (A), three transport devices 100 may be connected in the Y-axis direction by an AGV 101 or the like. In this example, the connecting parts are connecting members or the like that connect each of the transport devices 100. When connected by connecting members in this way, it is possible to prevent the transport devices 100 from becoming separated when used as scaffolding.

As shown in FIG. 11B, at installation position P2, the mesh ME is moved upward in the height direction to form a handrail HR. In this way, even when used in a linked configuration, if a handrail HR is provided, it can be used as a scaffold for working at heights.

In addition, the conveying device 100 may be used by connecting multiple conveying devices 100 together, for example, as follows.

Figure 12 is a diagram showing a fourth example of connecting multiple conveying devices. As shown in the figure, four conveying devices 100 may be connected in the X-axis direction (the short side direction of the conveying devices 100 in the figure) for use. In this type of connection, only the outermost mesh may become the handrail HR.

Figure 13 is a diagram showing a fifth example of connecting multiple conveying devices. As shown in the figure, four conveying devices 100 may be connected in pairs in the X-axis direction and the Y-axis direction (the short and long directions of the conveying devices 100 in the figure). In the case of such a connection, only the outermost mesh may serve as the handrail HR.

Note that more than the number of conveying devices 100 used in the above example may be connected together.

The conveying device 100 may also be fixed at the installation position P2.

As described above, by connecting and using the conveying device 100, work can be done efficiently over a wide area.

For example, the transport device 100 may be automatically transported by the AGV 101 after work is completed at night, etc. Specifically, the transport system performs a transport method such as the following.

Figure 14 shows an example of a transport method.

In step S1, the transport system inputs the storage of the equipment and the specified position. That is, in step S1, preparations for transport are made. That is, the transport device 100 stores the equipment. Furthermore, the AGV 101 inputs the specified position.

In step S2, the transport system performs a transport process to transport the transport device 100 to a predetermined location. For example, the transport process is performed after work is completed, i.e., at night. The predetermined location is a location inputted in step S1 using a map or the like, and is the location that will be the work site for the next job. Therefore, when the transport process is performed, the equipment and materials stored in step S1 are transported to the predetermined location.

In addition, it is desirable for the transport process to transport the transport device 100 to a predetermined position corresponding to the equipment. In such a case, step S1 or the like is used to associate each equipment with which work location it will be used at. The AGV 101 then uses a sensor or the like to determine what type of equipment is stored. In this way, the AGV 101 can determine the position to transport the transport device 100 to depending on the type of equipment.

For example, a combination of a blower and a duct connected to the blower is installed in the same location. In other words, various types of equipment and materials are used in the same work area. In this way, when the combination of equipment and materials to be used in the same work area is decided, the transport location for the combination may be input.

In addition, the work locations where materials or equipment or a combination of materials and equipment will be used are input in advance in the form of location information, etc. In this way, a matching process may be performed in which a specific location is matched to the materials and equipment, etc.

Therefore, once a specific position is determined for each equipment or material, it is possible to eliminate the need to repeatedly input the same data for multiple conveying devices 100, for example.

RFID (radio frequency identifier) or the like may also be used. First, an IC tag is attached to each piece of equipment in advance. The location where each piece of equipment is to be placed is then stored in the IC tag. By storing the location in advance in the IC tag in this way, the location where the equipment with the IC tag attached is to be placed can be determined by reading the IC tag. In this way, the IC tag may be attached and read to determine the location to which the transport device 100 is to be transported.

Or RFID may be used as follows:

First, for each transport device 100 or AGV 101, information such as the location to which the transport device 100 is transported, the type of equipment to be stored in the transport device 100 (i.e., the equipment to be used for work to be performed at the location to which the transport device 100 is transported), and the number of equipment is registered in an IC tag in advance. Then, the IC tag with the registered information may be installed on the transport device 100 or AGV 101.

With this configuration, when storing materials and equipment, the IC tag can be read to ascertain information about the materials and equipment to be stored in each transport device 100. Also, an IC tag on which information such as the type of material and equipment is registered can be attached to each piece of equipment, and a sensor installed in the AGV 101 or transport device 100 can read the IC tag to check whether the necessary materials and equipment are stored.

When the conveying system uses multiple conveying devices 100, the multiple conveying devices 100 may be connected as shown in Figures 9 to 13. In this way, when multiple conveying devices 100 are used, it is desirable to perform steps S3 and S4.

In step S3, the transport system determines whether or not to couple. If to couple (YES in step S3), the transport system proceeds to step S4. On the other hand, if to not couple (NO in step S3), the transport system proceeds to step S5. Note that the transport method may omit step S3 and the like, assuming that coupling is performed or not performed.

In step S4, the transport system performs a connection process to connect the ceiling sections. For example, the connection process is performed as shown in FIG. 9. Therefore, when the connection process is performed, the multiple transport devices 100 are connected and reach the state shown in FIGS. 9 to 13. In this way, when the connection process is performed, the transport devices 100 are connected, and the worker MN can secure a wide foothold.

In step S5, the conveying system performs a moving process to move the side portion. That is, the conveying system moves the mesh ME upward. Therefore, when the moving process is performed, the conveying device 100 changes from the state shown in FIG. 1 to the state shown in FIG. 2.

In step S6, the transport system performs an unloading process to unload the equipment and materials. For example, in the unloading process, the stored equipment and materials are made ready for use. Therefore, the unloading process maintains a state in which the opening OP is secured by a moving process or the like. Note that the unloading process may also be performed by, for example, moving the equipment and materials outside the transport device 100 by an actuator or the like.

In step S7, the transport system performs a boarding process in which a worker boards the ceiling. Work by the worker MN is performed at a pre-set work location. Therefore, when the transport device 100 is fixed at the work location, i.e., the specified position input in step S1, the worker MN can board the ceiling and perform work at a high place, as shown in FIG. 2. Therefore, the boarding process includes fixing the transport device 100 to the work location, etc.

Then, during the day, the worker MN performs construction work using the materials and equipment transported by the automatic transport process and the transport device 100, etc. Then, for the next construction work, the next installation position, etc. is input to the AGV 101, etc. Then, after the work is completed, step S8 is performed.

In step S8, the transport system performs an unloading process to unload the equipment and materials. For example, the equipment and materials to be unloaded are stored in the transport device 100 by the worker MN. Then, when the worker MN performs a predetermined operation (e.g., pressing a button), the transport device 100 starts unloading.

The conveying device 100 may start to be removed based on time, operation, or a combination of these.

For example, after completing a task, the worker MN performs an operation indicating that the task is completed (e.g., pressing a button, etc.). Next, after a predetermined time during which the worker MN can leave (e.g., one hour or more; the time is, for example, set in advance) has elapsed, the worker MN may be automatically removed.

Alternatively, first, in the work plan, a predetermined time is set in advance, which is any time after the work is completed (a time after a predetermined time has elapsed at which the worker MN can leave after the work is completed. For example, if the work is performed during the day, this time is a time that refers to nighttime). Then, the transport device 100 may be set to automatically be removed at the predetermined time.

When the above-described transportation method is performed, a transportation device that a worker can ride on can be provided to the work location. Furthermore, when each process in the transportation method is performed by the transportation system, a transportation device that a worker can ride on can be provided to the work location without the need for operation by a worker MN, etc.

The transportation process, etc., is not limited to being performed at night, but may also be performed while the workers MN, etc. are working. In particular, if the transportation process, etc., is performed after the work is completed, the materials and equipment can be transported to the work site without the workers MN having to operate it, thereby reducing the burden on the workers MN.

The transport method is not limited to a method in which the processes are performed at the timings shown above, or in the order of the processes shown in the figure. For example, step S1, etc. may be performed after work is completed. Furthermore, steps S4 and S5 may be performed in parallel. In this way, some or all of the processes may be performed in parallel or redundantly. The transport method may also include a process performed by a worker MN, etc.

Second Embodiment
15 is a diagram showing an example of the appearance of the transport device of the second embodiment. In the following diagrams, the short direction of one side of the transport device 100 is the X-axis (also referred to as the "horizontal direction"), and the long direction of one side of the transport device 100 is the Y-axis (also referred to as the "depth direction").

For example, two or more conveying devices 100 as shown in the figure are connected together to form a scaffold. Specifically, the conveying device 100 has the following dimensions and shape.

Figure 16 is a diagram showing an example of the dimensions and shape of the conveying device. Specifically, Figure 16 (A) is a so-called side view (shown on the Y-Z axis plane), mainly showing the side portion. As shown in the figure, the side portion is composed of, for example, multiple side plates PT. The state shown in Figure 16 (A) is a state in which some of the side plates PT have moved upward in the height direction.

Figure 16 (B) is a so-called top view (shown on the XY axis plane), and shows the state in which mainly the ceiling and side parts are used as scaffolding.

Figure 16 (C) is a so-called front view (shown on the X-Z axis plane), and shows the state in which mainly the ceiling and side sections are used as scaffolding. If the side shown in Figure 16 (A) is the flat side, then the side shown in Figure 16 (C) is the gable side.

Figures 16(D) and 16(E) are examples of structures for fixing the side panel PT. For example, if a structure using a latch stopper as shown in the figure is used, the side panel PT can be fixed at a predetermined height.

With a configuration equipped with side panels PT as shown in the figure, for example, as in the first embodiment, while the transport device 100 is transporting materials and equipment, the side panels PT can contain the materials and equipment within the transport device 100. When a worker MN rides on the ceiling, for example, as in the first embodiment, the side panels PT can be moved upward in the height direction to serve as handrails, thereby meeting the temporary equipment certification standards.

When connecting multiple transport devices 100, the side panels PT are used to connect and provide scaffolding. Specifically, the connections and scaffolding are provided by the following connection method.

<Example of a method for connecting a transport device>
FIG. 17 is a diagram showing an example of a method for connecting the transport device.

In step S21, the conveying system or the like conveys the conveying device 100. That is, the conveying device 100 is conveyed to the work location in step S21. Hereinafter, it is assumed that multiple conveying devices 100 are conveyed in step S21.

In step S22, it is determined whether the side portion is to be used as a scaffolding material or a handrail. In other words, it is determined for each side portion whether it is to be used as a scaffolding material or a handrail, and it is possible to select which for each side portion.

If the side portion is to be used as a scaffolding material (step S22: "Scaffolding material"), proceed to step S24. On the other hand, if the side portion is to be used as a handrail (step S22: "Handrail"), proceed to step S23.

In step S23, the side portion moves upward in the height direction and is fixed after the movement.

In step S24, the side portion is used to connect to another transport device and become a scaffolding material. Specifically, the side panel PT is operated as follows.

Figure 18 is a diagram (part 1) showing an example of connecting transport devices using the side sections to create scaffolding. First, as shown in the figure, the side panel PT is slid to the height at which the scaffolding material is to be constructed. The example shown is one in which the scaffolding material is installed at the same height as the ceiling. After this, the side panel PT is tilted around the Y axis (in the figure, it is rotated towards the front), resulting in the following state.

Figure 19 is a diagram (part 2) showing an example of connecting transport devices using the side portions to create scaffolding. As shown, the side panel PT is rotated about 90° around the Y axis from the state shown in Figure 18. In this way, the transport devices can be connected using the side panel PT, and scaffolding can be constructed. Specifically, the transport devices can be connected and scaffolding can be constructed as follows.

Figure 20 is a diagram (part 3) showing an example of connecting transport devices using the side parts to create a scaffold. The example shown is an example after connecting two transport devices using the connection method shown in Figure 17. When multiple transport devices 100 are connected as shown in the figure, a worker MN can use them, for example, as follows.

Figure 21 is a diagram (part 4) showing an example of connecting transport devices using the side parts to create scaffolding. Specifically, the example shown is an example in which four transport devices 100 are connected together. By connecting the transport devices 100 in this way, the ceiling parts and connecting parts can be used to construct scaffolding for working at heights.

On the other hand, side panels PT that do not form a connecting part and are located on the outer periphery, etc., can be used as handrails HR.

<Details of the connection part>
The connecting portion CN is formed, for example, by combining a side panel PT and a ceiling CE having the following shape.

Figure 22 is a diagram showing the details of the connection portion. The figure is an enlarged view of the portion (hereinafter referred to as the "tip portion PTL") where the side panel PT and the ceiling CE come into contact when they are connected in the scene where they are connected as in Figure 20. The example shown is an example of a configuration in which the tip portion PTL overlaps the end of the ceiling CE, and the side panel PT sits on top of the ceiling CE.

It is desirable for the tip PTL of the side panel PT, i.e. the part where it contacts the ceiling CE of the other transport device, to be "L" shaped or the like. In this way, when one of the parts that make up the connecting part is "L" shaped, the step in making the connecting part can be made smaller. In this example, the step is a protrusion that occurs where the side panel PT and the ceiling CE overlap (in the illustration, it is the difference in height in the upward direction on the Z axis based on the height of the ceiling CE). If such a step is large, the worker MN may easily trip over it, which may cause an accident. Therefore, an "L" shape like the tip PTL shown in the illustration makes it possible to make the step smaller and reduce the number of situations where the worker MN or the like trips over the step.

The side panel PT is also configured to be supported at a location other than the tip portion PTL. Specifically, this is supported by a support material SU or the like. For example, the support material SU is preferably composed of furring strips and an elastic material such as rubber. Using an elastic material can soften the impact that occurs when connecting the pieces.

The support material SU is shaped to protrude outward.

The support material SU supports the parts of the side panel PT other than the tip end PTL in the X-axis direction of the connection (left and right direction in FIG. 22) - that is, the parts of the side panel PT where there is thickness. Specifically, the support material SU is installed in a position that supports the side panel PT between the center of the side panel PT and the tip end PTL in the X-axis direction of the connection.

The support material SU is also installed at a height such that when connected, the side plate PT and the ceiling of the other transport device are flat. In other words, the support material SU is installed at a height adjusted so that no step is created when the side plate PT and the ceiling of the other transport device are connected. On the other hand, it is desirable for the support material SU to be adjusted to a height such that it supports the side plate PT and is not supported by just the tip portion PTL and the ceiling.

The tip portion PTL may be processed to be thin, and therefore is often not as strong as other portions of the structure. For this reason, it is desirable for the connection to be configured so that the support material SU mainly supports the side panel PT, rather than the tip portion PTL and the ceiling portion.

In this way, the side panel PT is also supported by the support material SU. In other words, when the side panel PT is supported at multiple points, it becomes a scaffolding material and can support the weight of the worker MN in a distributed manner.

The side panels PT (including the tip portion PTL) and the ceiling CE are made of a practical metal such as aluminum.

Third Embodiment
In the third embodiment, when multiple transport devices 100 are connected, the transport devices 100 are connected at different heights and serve as scaffolding for workers to stand on. Specifically, multiple transport devices 100 can be connected to form a scaffolding at the following height (hereinafter referred to as a "second height H2") in addition to the height shown in the second embodiment (hereinafter referred to as a "first height H1").

Figure 23 shows an example of connection at the second height.

The first height H1 is, for example, 1950 mm, and the second height H2 is 900 mm.

The first height H1 is, for example, the height used for facility construction work. On the other hand, the second height H2 is the height used for building construction work. In this way, if multiple heights can be set to suit the construction work, work such as changing the conveying device for each construction work can be reduced.

Switching between the first height H1 and the second height H2 is achieved by a mechanism that slides the side panel PT in the Z-axis direction. Such a sliding mechanism can prevent the side panel PT from being removed and lost.

Furthermore, the scaffolding other than the side panel PT is formed, for example, as follows:

Figure 24 shows an example of scaffolding formation. The portion shown (hereinafter referred to as "enlarged portion 200") is an enlarged portion of the angle bar PT2 etc. in Figure 28 (A).

For example, the scaffolding is formed by fitting the scaffolding board PT1 into the angle bar PT2. Specifically, the scaffolding is formed by fitting the pins on the scaffolding board PT1 into holes formed in the angle bar PT2.

With the above configuration, for example, a scaffolding like the one below can be constructed at the second height H2.

Figure 25 is a diagram showing an example of connecting transport devices using side parts to create scaffolding in the third embodiment. Specifically, the example shown in Figures 25(A) and 25(B) is an example in which four transport devices 100 are connected together, similar to Figure 21. By connecting the transport devices 100 in this way, a scaffold for work can be constructed using scaffolding boards and connecting parts.

Figure 26 is a diagram showing an example of movement lines. For example, with the configuration shown in Figure 25, worker MN can move along a line as shown in Figure 26 (in the figure, arrows indicate the locations where worker MN can move). In this way, a scaffold for worker MN can be constructed at the second height H2.

<Example of connection method>
FIG. 27 is a diagram showing an example of a connection method.

In step S31, the conveying system etc. conveys the conveying device 100, for example, in the same manner as in step S21 etc. In other words, the conveying device 100 is conveyed to the work location in step S31. Hereinafter, it is assumed that multiple conveying devices 100 are conveyed in step S31.

In step S32, it is determined whether the height at which the side part will build the scaffolding will be the first height or the second height. That is, in this example, the height can be selected from two types, the first height and the second height.

If the first height is to be selected ("First Height" in step S32), proceed to step S33. On the other hand, if the second height is to be selected ("Second Height" in step S32), proceed to step S34.

In step S33, the side portion is set to a first height and, after movement, is used for connection.

In step S34, the side portion is set to a second height and, after movement, is used for connection.

In this way, the scaffolding material is formed by connecting the conveying device to the side at the height selected by the judgment procedure such as step S32.

<Modification>
Fig. 28 is a diagram showing a modified example of the conveying device. For example, the conveying device 100 may be used in a configuration as shown in Fig. 28(A), a configuration as shown in Fig. 28(B), or a combination of the conveying devices shown in Fig. 28(A) and Fig. 28(B).

The conveying device 100 shown in FIG. 28(A) and FIG. 28(B) differ, for example, in the configuration of the outer frame (hereinafter referred to as the "outer frame 111") that supports the storage space and the ceiling portion, etc. Specifically, in the example shown in FIG. 28(A), the outer frame 111 is composed of two pillars. In this configuration, the support pillar and the slide rail (used for sliding the side panel and has a "U" shaped cross section) are separate. On the other hand, in the example shown in FIG. 28(B), the outer frame 111 is composed of one pillar. In this configuration, the pillar serves as both the support pillar and the slide rail. And with the configuration shown in FIG. 28(B), the dimension in the X-axis direction can be reduced. For example, the dimension in the X-axis direction can be reduced to about 1060 mm.

In this way, with a small conveying device 100 with a side dimension of 1060 mm or less, multiple conveying devices 100 can be mounted on a truck, etc., so four units can be mounted on a 10-ton truck, or two units can be mounted on a 4-ton truck.

Also, as shown in FIG. 28(B), the support material may have a shape that is partially removed from the shape shown in FIG. 28(A).

Furthermore, by positioning the support and the knee brace at different positions in the Y-axis direction, the dimension in the X-axis direction can be reduced.

In Fig. 28(B), in order to reduce the dimension in the width direction, the support posts (which also serve as slide rails) are closer to the inside than in Fig. 28(A). This configuration, that is, a configuration in which the same dimensions of scaffolding boards can be used between Fig. 28(A) and Fig. 28(B), is desirable. For example, as shown in Fig. 28(B), the ceiling CE is placed on the frame body (i.e., the 21st horizontal bar 100EH21, the 41st horizontal bar 100EH41, the 22nd horizontal bar 100EH22, and the 42nd horizontal bar 100EH42 in the example shown in Fig. 28(B), and a configuration in which the angle iron PT is eliminated from the configuration shown in Fig. 28(A).

The tip portion PTL may have the following shape:

Figure 29 is a diagram showing an example of the shape of the tip portion. For example, the tip portion PTL may have a shape as shown in Figures 29(A) to 29(I). Note that Figures 29(A) to 29(F) are enlarged views of the tip portion PTL. Meanwhile, Figures 29(G) to 29(I) are diagrams showing the entire side portion including the tip portion PTL.

For example, even in the shapes shown in Figures 29(A) to 29(F), the tip portion PTL (the part shown by the solid line in the figures, which is the right side) has a thinner shape with no thickness (the dimension in the vertical direction in the figures) than the other parts (the part shown by the dotted line in the figures, which is the left side). In this way, it is sufficient that all or part of the tip portion PTL has a shape that is thin. A shape that is thin in this way can reduce the step.

Also, the side portion may be constructed by combining multiple parts as shown in Figures 29(G) to 29(I) so that the area in contact with other conveying devices is thin.

The step is small if the tip portion PTL of the side portion and the ceiling portion of the other transport device with which the tip portion PTL comes into contact during the connection are flat. Therefore, it is desirable to process the tip portion PTL so that the connection portion is as flat as possible by processing the shape of the tip portion PTL, for example by making it thinner.

In particular, an "L" shape can reduce the step and can be easily manufactured using bending processes, etc.

The tip portion PTL and the ceiling CE may also be combined in a shape opposite to that shown above. That is, the ceiling CE may be "L" shaped, etc. Similarly, the support material SU may be provided by the side panel PT or by the ceiling CE. That is, in the example shown in FIG. 22, the support material SU is configured such that an elastic body is placed on top of the furring strips provided by the conveying device on the ceiling CE side, but the support material SU may, for example, be a structure in which the furring strips and the elastic body are integrated. The support material SU may also be configured in a way other than a furring strip and an elastic body.

The position, shape and material of the support material SU are not important as long as it can support the side panel PT. For example, the support material SU may be metal, wood, an elastic material, or a combination of these.

The side panel PT may be configured to be supported by the tip portion PTL and the support material SU. In other words, the side panel PT may be configured to be supported not only by the support material SU, but also by the tip portion PTL, etc.

The connecting portion may also be configured as follows:

Figure 30 shows a first modified example of the connecting portion. For example, as shown in the figure, it is desirable to provide an angle portion C1 on the side panel PT, and a receiving portion C2 for hooking the angle portion C1 on the other ceiling CE (which will be another transport device). Note that the receiving portion C2 may be made of a support material SU or the like. In other words, it may be configured to support the side panel and to engage with the angle portion C1. Also, the receiving portion C2 may have a shape as shown in Figure 28 (B) instead of the shape shown in the figure.

In this way, when the angle portion C1 and the receiving portion C2 are configured to fit together, the connection is unlikely to come loose even if the transport device to which they are connected moves. Therefore, when the angle portion C1 and the receiving portion C2 are configured to fit together using the protruding shape, the connection can be easily maintained.

Furthermore, it is preferable that the side panel PT has the following configuration:

Figure 31 is a diagram showing a second modified example of the connecting portion. As shown in Figure 31 (A), it is preferable that the side plate PT is configured to include an auxiliary plate PTA. For example, the auxiliary plate PTA has a structure that allows it to slide in the Y-axis direction. In this way, if the auxiliary plate PTA can slide, it can be moved to a position such as that shown in Figure 31 (B).

If the auxiliary plate PTA is located in the position shown in Figure 31 (B), it can close the gap between the side panels PT and PT. Such a gap can cause workers MN, etc. to trip, which can lead to accidents. Therefore, if the auxiliary plate PTA can close the gap, it can reduce the number of incidents where workers MN, etc. trip.

For example, as shown in FIG. 19, the side panel PT includes a portion that can be rotated to form a foothold, i.e., horizontal (hereinafter referred to as "horizontal portion PT10"), and a portion that remains vertical even after rotation (hereinafter referred to as "vertical portion PT11"). As shown in the figure, when comparing the length of the horizontal portion PT10 in the Y-axis direction (hereinafter referred to as "horizontal portion dimension L10") with the length of the vertical portion PT11 in the Y-axis direction (hereinafter referred to as "vertical portion dimension L11"), the vertical portion dimension L11 may be wider than the horizontal portion dimension L10. For example, when a mechanism for sliding is provided, the horizontal portion PT10 will have mechanisms on both ends, resulting in a narrower width.

When these dimensions are connected, gaps are likely to occur at the boundary between the horizontal section PT10 and the horizontal section PT10 of the other transport device to be connected. Therefore, it is desirable to have a configuration in which the auxiliary plate PTA closes the gap that occurs at the boundary.

Gaps can cause workers to trip or fall. Therefore, by sealing the gaps with the PTA support plate, accidents such as tripping can be prevented.

The other side portion may be a side portion provided on another conveying device (i.e., an adjacent conveying device connected to the conveying device) or may be another side portion provided on the own device.

Figure 32 shows a modified example that uses knee braces. As shown in the figure, it is preferable that the side panel PT has a knee brace PTB. The knee brace PTB has a built-in locking mechanism.

When connecting, the knee brace PTB is unlocked before use. When the lock is released, the side panel PT can be rotated about 90° around the Y axis, with the hinge as the fulcrum, as shown in Figure 19. With a configuration that includes such a knee brace PTB, the side panel PT can be maintained in a stable state. Therefore, when used as a handrail, for example, it is unlikely to fall over even if a horizontal force is applied, ensuring safety.

It is also desirable that the support material SU is installed so as to avoid the knee braces PTB. This configuration allows the width of the conveying device to be reduced. When the support material SU is installed so as to avoid the knee braces PTB in this way, the support material SU does not have a continuous shape as shown in Figure 30, but is configured to support the side portion at both ends of the side portion, as shown in Figure 28 (B), for example. In such a case, it is desirable that the side portion is supported not only by the support material SU but also by the tip portion PTL, so that the side portion can be supported at many points.

It is also desirable to have a handrail on the so-called gable side, as shown below.

Figure 33 shows a modified example in which a handrail is formed on the end side. For example, it is desirable for the transport device to have a handrail member HRP as shown in Figure 33 (A).

For example, as shown in FIG. 33(B), the handrail member HRP is connected to a handrail member HRP of another transport device to form a handrail. The handrail member HRP is stored on the end side of the transport device 100 (in the figure, this is the position indicated by the handrail storage section 110) during transport, for example. The handrail member HRP may also be stored in a location other than the handrail storage section 110.

When connecting, as shown in Figure 33 (C), the handrail member HRP can be spread out and connected to the handrail member HRP of another transport device to form a handrail, as shown in Figure 33 (B). In this way, a configuration in which a handrail can be formed on the gable side as well is desirable. With such a handrail on the gable side, it can be used as a safer scaffolding material.

The height may be set to three or more different levels. The height may be changed by a mechanism other than sliding the side portion. For example, the side panel PT may be detachable from and attachable to the conveying device. Alternatively, the side panel PT may be installed separately for each height.

The connection method may be achieved by manual operation, or may be achieved by a conveying system or the like, with the mechanism being driven by an actuator and a control device, etc.

In addition, in the illustrated examples, the illustration of parts, etc. may be omitted in order to make the illustration easier to see. Therefore, the conveying device 100 may be configured to have parts other than those shown in the illustration.

For example, as shown in FIG. 26, it is desirable that the side parts that are not used as scaffolding can be fixed in an upright position without being removed. If the side parts are removed, they may get lost. Therefore, if they are not used as scaffolding, for example, if the side parts can be fixed to the transport device 100 as shown in FIG. 26, they can be prevented from getting lost.

For example, the transport device 100 is realized by attaching wheels to a rectangular parallelepiped framework, as shown in FIG. 15 and FIG. 28. Specifically, the framework is composed of a rod-shaped member positioned vertically along the Z-axis direction (hereinafter referred to as the "first vertical rod"; hereinafter, an example will be described based on the "first vertical rod 100EV1" in the figure), three rod-shaped members (hereinafter referred to as the "second vertical rod", "third vertical rod" and "fourth vertical rod") that are installed parallel to the first vertical rod, i.e., positioned vertically along the Z-axis direction, and rod-shaped members that are perpendicular to the first to fourth vertical rods. For example, the first vertical rod 100EV1, the second vertical rod 100EV2, the third vertical rod 100EV3 and the fourth vertical rod 100EV4 are all vertical and are positioned at the four corners of the transport device 100.

Hereinafter, a rod-shaped member perpendicular to the first vertical rod 100EV1 to the fourth vertical rod 100EV4, i.e., a rod-shaped member positioned horizontally with respect to the X-Y plane, will be referred to as a "horizontal rod". For example, two horizontal rods are installed between each of the first vertical rod 100EV1 to the fourth vertical rod 100EV4. Specifically, two horizontal rods (hereinafter referred to as the "eleventh horizontal rod 100EH11" and the "twelfth horizontal rod 100EH12") are installed between the first vertical rod 100EV1 and the second vertical rod 100EV2. In other words, the eleventh horizontal rod 100EH11 and the twelfth horizontal rod 100EH12 are parallel to the X-axis and perpendicular to the first vertical rod 100EV1 and the second vertical rod 100EV2. The eleventh horizontal bar 100EH11 and the twelfth horizontal bar 100EH12 are fixed to the first vertical bar 100EV1 and the second vertical bar 100EV2 by welding, screwing, or the like. Note that the vertical and horizontal bars are not limited to being rod-shaped, and may be multiple parts or plates, etc. Also, the horizontal bars, etc. are not limited to being parallel to each other as shown in the figure, and may be intersecting, etc.

Horizontal bars (hereinafter referred to as the "21st horizontal bar 100EH21" and the "22nd horizontal bar 100EH22") are installed between the second vertical bar 100EV2 and the third vertical bar 100EV3. That is, the 21st horizontal bar 100EH21 and the 22nd horizontal bar 100EH22 are parallel to the Y-axis and perpendicular to the second vertical bar 100EV2 and the third vertical bar 100EV3. The 21st horizontal bar 100EH21 and the 22nd horizontal bar 100EH22 are fixed to the second vertical bar 100EV2 and the third vertical bar 100EV3 by welding or screwing, etc.

Two horizontal bars (hereinafter referred to as the "31st horizontal bar 100EH31" and the "32nd horizontal bar 100EH32") are installed between the third vertical bar 100EV3 and the fourth vertical bar 100EV4. That is, the 31st horizontal bar 100EH31 and the 32nd horizontal bar 100EH32 are parallel to the X-axis and perpendicular to the third vertical bar 100EV3 and the fourth vertical bar 100EV4. The 31st horizontal bar 100EH31 and the 32nd horizontal bar 100EH32 are fixed to the third vertical bar 100EV3 and the fourth vertical bar 100EV4 by welding or screwing, etc.

Two horizontal bars (hereinafter referred to as "41st horizontal bar 100EH41" and "42nd horizontal bar 100EH42") are installed between the 4th vertical bar 100EV4 and the 1st vertical bar 100EV1. That is, the 41st horizontal bar 100EH41 and the 42nd horizontal bar 100EH42 are parallel to the Y-axis and perpendicular to the 4th vertical bar 100EV4 and the 1st vertical bar 100EV1. The 41st horizontal bar 100EH41 and the 42nd horizontal bar 100EH42 are fixed to the 4th vertical bar 100EV4 and the 1st vertical bar 100EV1 by welding or screwing, etc.

In this way, the framework is a structure including the first vertical rod 100EV1 to the fourth vertical rod 100EV4, and the eleventh horizontal rod 100EH11 to the forty-second horizontal rod 100EH42, etc.

The side panel PT is installed, for example, between the first vertical bar 100EV1 and the fourth vertical bar 100EV4. The side panel PT has a mechanism that slides up and down along the first vertical bar 100EV1 and the fourth vertical bar 100EV4. Similarly, the side panel PT is installed, for example, between the second vertical bar 100EV2 and the third vertical bar 100EV3. In this case, the side panel PT has a mechanism that slides up and down along the second vertical bar 100EV2 and the third vertical bar 100EV3.

The number of vertical and horizontal rods and their installation positions are not limited to those shown in Figures 15 and 28. In other words, as long as the framework formed by the vertical and horizontal rods functions as storage and scaffolding, the shape and components are not limited to those shown in the figures.

The numerical values of the dimensions described above are merely examples, and a person skilled in the art can appropriately adopt the dimensions depending on the intended use of the conveying device, etc.
