Description

Self-supporting type heavyweight high altitude lifting apparatus and installation method for the same}

The present invention relates to a high-altitude lifting device for ultra-heavy materials capable of lifting heavy objects to an altitude of tens of meters or more and an installation method thereof. More specifically, the present invention relates to a self-supporting high-altitude lifting device for ultra-heavy materials that is self-installed and self-supporting without separate installation equipment and its installation. It's about method.

In facilities that manufacture large-scale equipment, lifting of heavy objects occurs frequently. For example, at construction sites where plants with dozens of floors or more are being built, or yards where large ships are being built, ultra-heavy objects (e.g., ship blocks, etc.) weighing more than tens of tons are lifted to a considerable height.

Lifting of such ultra-heavy objects can be done using already installed equipment, such as a Goliath crane, but if there is no lifting equipment, it becomes necessary to install the lifting equipment itself. Additionally, the need to lift heavy objects often arises even in situations where there is no appropriate lifting equipment.

In such cases, the use of mobile cranes (e.g., Republic of Korea Patent 10-2008-0038034, etc.) may be considered at some sites, but in practice, they are unsuitable for vertically lifting ultra-heavy objects of tens of tons or more, making them difficult to use. there is.

In addition, there is a problem of delaying the process because additional installation equipment and other high-altitude lifting equipment are required to install a suitable crane at the required location. Due to these problems, lifting heavy objects is restricted in various situations, but an appropriate alternative has not yet been proposed.

Advantages and features of the present invention and methods for achieving them will become clear by referring to the embodiments described in detail below along with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below and may be implemented in various different forms, and the present embodiments are only provided to ensure that the disclosure of the present invention is complete and to provide common knowledge in the technical field to which the present invention pertains. It is provided to fully inform those who have the scope of the invention, and the invention is merely defined by the claims. Like reference numerals refer to like elements throughout the specification.

Hereinafter, with reference to FIGS. 1 to 13, the self-supporting ultra-heavy object aerial lifting device and its installation method according to the present invention will be described in detail. First, the aerial lifting device will be described in detail with reference to FIGS. 1 to 6, and then the installation method of the aerial lifting device will be described in detail with reference to FIGS. 7 to 13.

First, the self-supporting ultra-heavy object high-altitude lifting device will be described in detail.

Figure 1 is a perspective view of a self-supporting high-altitude lifting device for ultra-heavy objects according to an embodiment of the present invention, and Figure 2 is a diagram illustrating an applicable arrangement of the high-altitude lifting device of Figure 1.

Referring to FIG. 1, the self-supporting ultra-heavy object aerial lifting device 1 (hereinafter referred to as aerial lifting device) according to the present invention includes a frame tower 20-1 formed by assembling a plurality of frame blocks 20. The height of the frame tower (20-1) is adjusted according to the number of frame blocks (20). Therefore, by increasing the number of frame blocks 20, a frame tower 20-1 of a desired height can be formed and a heavy body can be lifted along the frame tower 20-1.

An elevating frame (10) is placed at the top of the frame tower (20-1). The frame block 20 is assembled inside the lifting frame 10 and also functions as a support body for supporting the lifting frame 10. Therefore, the lifting frame 10 can move to the top of the frame block 20 and stack the frame blocks 20 downward. Because of this, the present invention is capable of working at high altitudes with the lifting frame 10, so it can be installed on its own without the help of other equipment (cranes, etc.).

In addition, the high-altitude lifting device (1) has a variable crane module (110) placed on the lifting frame (10) that expands and contracts in the horizontal direction, distributes the load of the frame block (20) during towing, and moves the frame block (20) along the shortest possible path. It is supplied to the assembly space (inside the lifting frame). Therefore, the installation process progresses more quickly and efficiently.

The high-altitude lifting device 1 of the present invention is configured as follows. The high-altitude lifting device (1) includes a passage (11) formed on the side and an internal space connected to the passage (11), a lifting frame (10) with an opening (12) formed at the bottom, and is disposed at the top of the lifting frame (10). The variable crane module 110 is expanded in the horizontal direction and is formed to horizontally move the tow hook 117 into and out of the lifting frame. It is towed by the variable crane module 110 and the lifting frame ( 10) A frame tower (20-1) consisting of n frame blocks (20) (n is a natural number equal to or greater than 2) that are introduced into the interior and stacked and assembled downward to the lifting frame (10) through the opening (12), n frames. The unit rails 30 formed in each block 20 are connected in the vertical direction and are detachably coupled to the vertical rail portion 30-1 arranged along the frame tower 20-1 and the lifting frame 10. It includes a towing jack module 210 that adjusts the position of the lifting frame 10 on the unit rail 30 or separates from the lifting frame 10 and moves the vertical rail part 30-1 to tow a heavy object. (In Figure 1, the towing jack module is shown separated from the lifting frame).

According to one embodiment of the present invention, the variable crane module 110 includes a horizontal guide bar 114 that protrudes in the horizontal direction from the top of the lifting frame 10 and whose end is disposed outside the lifting frame 10, and three joints ( 8) and a pulley (see 115 in FIG. 8) is disposed at each node. The first node 111 is fixed to the horizontal guide bar 114 and the second node 112 is a horizontal guide. It may include a two-section link part (110a) that slides along the bar (114) to horizontally move the tow hook (117). In addition, it further includes a gap control cylinder 116 that expands and contracts between both ends across the third node of the two-bar link part 110a (see 113 in FIG. 8) to adjust the degree of opening of the two-bar link part 110a. can do.

In addition, the towing jack module 210 is separated up and down and includes a lower jack (see 212 in FIG. 3) and an upper jack (see 211 in FIG. 3) that pressurize and fix the vertical rail portion (30-1), and a lower jack and an upper jack. Including an adjustment cylinder (see 213 and 214 in FIG. 3) that adjusts the distance of the jack, it can be lifted along the vertical rail portion 30-1 by changing the distance between the lower jack and the upper jack.

In Figure 1, the towing jack module 210 is shown separated from the lifting frame 10 and prepared to lift a heavy object. However, the towing jack module 210 can be reconnected to the lifting frame 10 at any time when necessary (e.g., when installing or dismantling the device) and used to adjust the position of the lifting frame 10.

Hereinafter, based on one embodiment of the present invention, the configuration and effects of the present invention will be described in more detail.

Referring to Figure 1, the lifting frame 10 includes a passage 11 formed on the side and an internal space connected to the passage 11. The lifting frame 10 may be a structure composed of a plurality of frames, and the passage 11 may be formed by appropriately configuring the frames. The lifting frame 10 includes an opening 12 at the bottom connected to the internal space.

The internal space of the lifting frame 10 may be sized to allow one or more frame blocks 20 to enter. For example, the internal space may have a length that can accommodate at least one frame block 20 and a portion of another frame block 20 at the same time. The inner space of this lifting frame (10) is used as an assembly space connecting the upper and lower ends of the two frame blocks (20).

The lifting frame 10 may include a support 15 extending outward at the bottom. The support 15 is used to support the lifting frame 10 from the ground (or base on the ground) at the beginning of the installation process of the present invention. Within such limits, the shape of the support 15 may be modified into other forms.

A work deck 17 may also be placed on one side of the lifting frame 10. The work deck 17 can provide a work space and movement path for workers. The work deck 17 can be placed at an appropriate point on the lifting frame 10, so it is not limited to the drawing, but is installed in a position that does not overlap with the passage 11 and the opening 12 of the lifting frame 10. It is desirable to be Therefore, the work deck 17 may be formed integrally with the support 15 on the support 15 as shown. Structures such as railings may also be formed on the deck. Since the shape of the deck can be modified to any extent, the drawing is illustrative, and if necessary, additional decks can be placed at other points in the lifting frame.

The lifting frame 10 may have a support structure such as a roof 13 (roof) formed at the top. For example, there may be a cutout or groove in the center of the loop 13 that can be entered and removed from the outside (hidden by overlapping with the variable crane module). Therefore, the tow hook 117 and wire 118 can enter the inside of the lifting frame through the structure (see operation in FIG. 9). If necessary, the rigidity of the roof 13 can be supplemented by forming a reinforcing structure on the top of the roof 13 that does not interfere with the variable crane module 110.

The variable crane module 110 is placed at the top of the lifting frame 10. The variable crane module 110 expands and contracts in the horizontal direction and is configured to horizontally move the tow hook 117 into and out of the lifting frame 10. The variable crane module 110 may have a structure that is towed using a wire 118, and therefore the wire 118 may be connected to the winch 41 disposed on the base 40 on the ground. The traction hook 117 may be disposed at the end of the wire 118.

For example, the variable crane module 110 may be arranged to overlap the cutout or groove of the roof 13. The variable crane module 110 itself may function as a reinforcing structure supporting both sides of the incision area. For example, the cutout may be located inside the horizontal guide bar 114.

More specifically, the variable crane module 110 has a horizontal guide bar 114 that protrudes in the horizontal direction from the top of the lifting frame 10 and has an end disposed outside the lifting frame, three nodes, and a pulley is disposed at each node. Includes a two-section link portion (110a). The first node of the two-bar link unit (110a) is fixed to the horizontal guide bar 114, and the second node slides along the horizontal guide bar 114 to horizontally move the traction hook 117.

The two-section link portion 110a includes a pulley at each node, and the wire 118 extends along the pulley. Since the double-bar link portion is variable, the arrangement of the wire 118 extending along the pulley and the position of the traction hook 117 at the end of the wire 118 also change depending on the deformation of the double-bar link portion (110a). In particular, the two-bar link part (110a) is transformed with the interval control cylinder 116 that adjusts the degree of opening of the two-bar link part (110a), and the pulley is disposed below the node (particularly the second node (see 112 in FIG. 9)). The hanging towing hook (117) can be moved horizontally. Through this, the frame block can be retracted by inserting and retracting the tow hook 117 into and out of the lifting frame 10. The specific structure and operation of the variable crane module 110 will be described in more detail in the installation method of the present invention described later.

The frame tower 20-1 is formed of a plurality of frame blocks 20 assembled inside the lifting frame 10. That is, as described later, it is towed by the variable crane module 110 and introduced into the lifting frame 10 through the passage 11 on the side of the lifting frame 10 (see FIGS. 11 and 12), thereby forming the lifting frame. (10) A frame made of n frame blocks 20 (n is a natural number of 2 or more, which can be increased as necessary considering the load) stacked and assembled downwards of the lifting frame 10 through the opening 12 in the lower part. A tower (20-1) can be formed.

Since the length of the frame tower 20-1 changes depending on the number of frame blocks 20, the length can be increased to the height required to lift heavy objects. In addition, it can be installed more easily because it is installed by itself by lifting the lifting frame 10 and assembling the frame blocks 20 by stacking them. The installation method of the device, including the assembly method of the frame tower 20-1, will be described in more detail later.

The vertical rail unit 30-1 is a frame tower 20-1 in which unit rails 30 formed on each of the n frame blocks 20 (i.e., all of the plurality of frame blocks constituting the frame tower) are connected in the vertical direction. are arranged according to The vertical rail portion 30-1 may be a connection body of unit rails 30 formed in the vertical direction of each frame block 20. The vertical rail portion 30-1 is assembled together when assembling the frame block 20, and the overall length may be the same as the length of the frame tower 20-1.

As shown, unit rails 30 may be arranged in pairs on the frame block 20. Accordingly, the vertical rail portions 30-1 to which pairs of unit rails 30 are connected may also be arranged in pairs. If necessary, the pair of unit rails 30 can be increased, and the number of vertical rail parts 30-1 can also be increased. Alternatively, it is possible to use multiple surfaces of the frame block 20 to form a plurality of unit rails 30 on different surfaces and to arrange a plurality of vertical rail parts 30-1 on different surfaces. The number or arrangement of the vertical rail portions 30-1 can be modified in various ways.

The towing jack module 210 moves along the vertical rail portion 30-1 and lifts heavy objects. As described above, the towing jack module 210 is detachably coupled to the lifting frame 10 and can perform different functions as needed. The towing jack module 210 is detachably coupled to the lifting frame 10 and adjusts the position of the lifting frame 10 on the unit rail 30 of each frame block 20 (when installing and dismantling the device). Alternatively, (see FIGS. 8 and 11), it can be separated from the lifting frame 10 as shown in FIG. 1 (after installation is completed), and heavy objects can be towed by moving the vertical rail portion 30-1.

In this way, the high-altitude lifting device 1 of the present invention can be configured, and can be used to lift heavy objects in various ways as follows. Hereinafter, an example of the use of the high-altitude lifting device 1 and the operation method of the towing jack module 210 will be described in more detail.

Figure 2 is a diagram illustrating an applicable arrangement of the high-altitude lifting device of Figure 1, Figures 3 and 4 are diagrams of the use state of the high-altitude lifting device of Figure 2, and Figures 5 and 6 are towing jack modules of the high-altitude lifting device. This is also the operation of .

Referring to Figure 2, the high-altitude lifting device 1 can be used, for example, by placing a pair side by side. The vertical rail parts (30-1) of the two high-altitude lifting devices (1) are arranged to face each other, a loading bar (50) crossing between the vertical rail parts (30-1) is installed, and each of the loading bars (50) is installed. By connecting the towing jack module 210 of the high-altitude lifting device 1, a heavy object mounted on the loading bar 50 can be towed into the sky.

However, this is an example and does not need to be limited to this. If necessary, the high-altitude lifting device (1) can be used alone without the loading bar (50). In addition, when the load of a heavy object is very large, the number of high-altitude lifting devices 1 may be further increased and the heavy object may be lifted while operating a plurality of high-altitude lifting devices 1 (for example, three or four or more) together. The high-altitude lifting device (1) of the present invention can be self-installed, so it can be easily placed and used at any necessary point, and its height can be adjusted, so it is also possible to form a plurality of high-altitude lifting devices (1) at different heights depending on the situation. possible.

If explained based on the illustrated arrangement, the high-altitude lifting device 1 can load and lift a heavy object A on the loading bar 50 as shown in FIG. 3. At this time, the towing jack module 210 of each high-altitude lifting device 1 can move in synchronization at the same time. The towing jack module 210 may operate in such a way that the upper jack 211 and the lower jack 212 repeatedly pressurize and fix the vertical rail portion 30-1 and the distance between the two jacks changes. The specific operation of the towing jack module 210 will be described later (the enlarged view of FIG. 3 shows the front of the towing jack module).

Meanwhile, the high-altitude lifting device 1 may tow a heavy object A by hanging it on the loading bar 50 using a towing wire below, as shown in FIG. 4 . In addition, various possible traction methods can be applied, and the traction method can be selected by appropriately considering the shape, load, and center of gravity position of the heavy object (A).

Referring to Figures 5 and 6, the above-described towing jack module 210 may operate as follows. First, looking at the structure, the towing jack module 210 may include a lower jack 212 and an upper jack 211 separated up and down, and an adjustment cylinder that adjusts the distance between the upper jack and the lower jack. The lower jack 212, the upper jack 211, and the adjustment cylinder can all be formed as a symmetrical pair with the vertical rail portion 30-1 in between. The pair of first adjustment cylinders 213 disposed on both sides with the vertical rail portion 30-1 in between may be fixed to the same body or support so as not to spread apart from each other.

The adjustment cylinder may include a first adjustment cylinder 213 and a second adjustment cylinder 214. The lower jack 212 and the upper jack 211 have substantially the same structure and can be connected to each other by the first adjustment cylinder 213 and the second adjustment cylinder 214 as follows.

Both the lower jack 212 and the upper jack 211 are formed of a structure including a wedge portion 210a, an inclined surface portion 210b, and a connecting link 210c connected between the wedge portion 210a and the inclined surface portion 210b. It can be. One side of the wedge portion 210a faces the vertical rail portion 30-1, and the other side has an inclined surface formed so that it can contact the inclined surface portion 210b. The inclined surface portion 210b may be formed as a pressing block with an inclined surface corresponding to the inclined surface of the wedge portion 210a formed on one side.

The first adjustment cylinder 213 is vertically connected at both ends to the inclined surface portion 210b of the lower jack 212 and the inclined surface portion 210b of the upper jack 211, so that the gap between the two inclined surfaces 210b can be adjusted. is formed. In addition, the second adjustment cylinder 214 is vertically connected at both ends to the wedge portion 210a of the lower jack 212 and the wedge portion 210a of the upper jack 211 to adjust the gap between the two wedge portions 210a. It is formed so that it can be formed.

From this structure, the following operations are possible.

First, as shown in (a) of Figure 5, only the lower jack 212 is fixed to the vertical rail portion 30-1, and the upper jack 211 can be released. At this time, the first adjustment cylinder 213 is in a fixed state, and the second adjustment cylinder 214 slightly adjusts the wedge portion 210a of the upper jack 211 downward to the inclined surface portion 210b through fine adjustment (approximately 20 mm contraction). It can be moved. Since the upper jack 211 and the inclined surface portion 210b are connected by a connecting link 210c, the wedge portion 210a rotates toward the inclined surface portion 210b and moves along the inclined surface portion 210b in the direction where the inclined surface is widened. . Because of this, only the top jack 211 can be separated from the vertical rail portion 30-1.

In this state, when the upper jack 211 is released and the first adjustment cylinder 213 and the second adjustment cylinder 214 are simultaneously extended (approximately 320 mm can be extended) as shown in (b) of FIG. 5, the upper jack 211 ) is raised from the previous position as the distance from the lower jack 212 increases.

The raised upper jack 211 can be engaged again with the vertical rail portion 30-1, as shown in (c) of FIG. 5. At this time, the second adjustment cylinder 214 is fixed, and the first adjustment cylinder 213 slightly moves the inclined surface portion 210b of the upper jack 211 downward to the wedge portion 210a through fine adjustment (approximately 20 mm contraction). I order it. When the inclined surface portion 210b presses the wedge portion 210a due to the inclined surface action, the upper jack 211 is again fixed to the vertical rail portion 30-1.

At this time, as shown in (d) of FIG. 6, when the first adjustment cylinder 213 is further finely adjusted (contracted by approximately 20 mm), the inclined surface portion 210b of the lower jack 212 is slightly moved upward to the wedge portion 210a. Only the bottom jack (212) can be released. The wedge portion 210a of the upper jack 211 does not move due to the fixation of the second adjustment cylinder 214, and as the first adjustment cylinder 213 contracts, the vertical rail portion ( 30-1), so only the upper jack (211) is engaged with the vertical rail portion (30-1), and the lower jack (212) is released.

In this state, when the lower jack 212 is released and the first adjustment cylinder 213 and the second adjustment cylinder 214 are simultaneously contracted (approximately 300 mm can be contracted) as shown in (e) of Figure 6, the lower jack (approximately 300 mm can be contracted) 212) The distance from the top jack 211 is reduced and it is raised from the previous position.

The raised lower jack 212 can also be bitten into the vertical rail portion 30-1 again, as shown in (f) of FIG. 6. At this time, the first adjustment cylinder 213 is fixed, and the second adjustment cylinder 214 moves the wedge portion 210a of the lower jack 212 slightly upward to the inclined surface portion 210b through fine adjustment (approximately 20 mm contraction). You can do it. The wedge portion 210a of the lower jack 212 rotates toward the vertical rail portion 30-1 by the connecting link 210c and moves along the inclined surface portion 210b in the direction in which the inclined surface narrows, so that the lower jack 212 It can be fixed again to this vertical rail portion (30-1).

At this time, as shown in Figure 6 (g), when the second adjustment cylinder 214 is further finely adjusted (approximately 20 mm contracted), the wedge portion 210a of the upper jack 211 is slightly moved to the bottom of the inclined surface portion 210b and the upper Only Jack (211) is released. Through this, it is possible to return to the same state as (a) in Figure 5. Through this operation, a vertical movement sequence of the towing jack module 210 can be configured, and by repeating this, it is possible to lift a tonne weight body to a high altitude while repeatedly fixing it on the vertical rail portion.

However, if necessary, the structure of the towing jack module 210 may be changed, so there is no need to limit it to this understanding. For example, it is possible to construct another type of towing jack module 210 by using another type of lifting jack device or lifting structure that can move along the vertical rail portion 30-1. In this way, the high-altitude lifting device 1 can be formed and used to lift heavy objects.

Hereinafter, the installation method of the above-described high-altitude lifting device will be described in detail with reference to FIGS. 7 to 13. Since the installation method described below is a method for installing the high-altitude lifting device of the present invention, unless otherwise specified, repetition of the configuration described above will be omitted. However, if there is an additional or detailed explanation of the above-described configuration in the method description, this is considered to be an equivalent explanation for the above-mentioned device. The method description is carried out based on the flow chart in FIG. 7, with reference to other drawings as necessary.

Figure 7 is a flowchart showing a method of installing a self-supporting ultra-heavy object aerial lifting device according to an embodiment of the present invention.

Referring to Figure 7, the installation method of the high-altitude lifting device according to the present invention includes the following steps. The installation method of the high-altitude lifting device includes the step of towing the other frame block with a variable crane module, with one frame block among the n frame blocks (n is a natural number of 2 or more) constituting the frame tower inside the lifting frame. (S200) [step (a) - see (d) of FIG. 10], vertically moving the lifting frame along the unit rail formed in the frame block to raise the lower end of the lifting frame to the top of the frame block (S300) ) [Step (b) - see (b) in Figure 11], and fix the lifting frame and insert the other frame block into the lifting frame with a variable crane module, and press the lower end of the other frame block inside the lifting frame. It includes a step (S400) of connecting and stacking one frame block on top (step (c) - see Figure 12).

At this time, one frame block and another frame block have no other meaning other than to distinguish between the frame block introduced first and the frame block introduced later into the lifting frame. Therefore, the above steps can be equally applied to assembling any two frame blocks in the process of sequentially stacking a plurality of frame blocks. That is, the above steps can be repeatedly applied to sequentially stack n frame blocks.

In one embodiment of the present invention, before the step (a) (S200), in a state where the lifting frame is located on the ground and the inside is empty, any one of the n frame blocks is towed with a variable crane module and placed inside the lifting frame. It may further include a placing step (S100) (see (c) of FIG. 10). In addition, after step (c) (S400), a frame tower is formed by connecting the bottom of the nth (i.e. last) frame block to the top of the n-1th frame block inside the lifting frame, and the lifting frame is connected to the n-1th frame. A step (S500) [see FIG. 13] of lowering the block along the unit rail formed on the block and seating it on the top of the frame tower may be further included.

In other words, the starting step (S100) of placing the first frame block inside the lifting frame on the ground, and the assembly step (S200 to S400) are repeated to assemble the last (nth) frame block and attach the lifting frame to the completed frame tower. Self-installation can be completed by combining (S500). In addition, although not shown in Figure 7, after the lifting frame is seated on the top of the frame tower, the towing jack module detachably coupled to the lifting frame is separated from the lifting frame and placed on the vertical rail portion arranged along the frame tower. By further including the step [see (b) of FIG. 13], it can be prepared for lifting heavy objects.

Hereinafter, the installation method of the high-altitude lifting device according to the present invention will be described in more detail based on an embodiment of the present invention.

Before explaining the method, first, referring to FIGS. 8 and 9, the structure and operation of the variable crane module, the detailed structure of the lifting frame, and the connection structure of the frame block related to the installation operation of the device will be described in more detail.

Figure 8 is an enlarged perspective view of the lifting frame and frame module of Figure 1, and Figure 9 is an operating diagram of the variable crane module disposed on the lifting frame of Figure 8.

Referring to FIG. 8, the variable crane module 110 includes a horizontal guide bar 114 that protrudes in the horizontal direction from the top of the lifting frame 10 and whose end is disposed outside the lifting frame 10, as described above. The horizontal guide bar 114 forms a horizontal expansion structure of the variable crane module 110. The horizontal guide bar 114 includes a long hole 114a cut in the horizontal direction, so that the second node 112 of the above-described two-section link part 110a can be moved in the horizontal direction along the long hole 114a.

The horizontal guide bar 114 may protrude out of the lifting frame 10 at an appropriate length. The protrusion length is adjustable, so it does not need to be limited to the drawing. For example, as shown in FIG. 10, the horizontal guide bar 114 may have a long end protruding to one side.

The two-bar link portion (110a) has a first node (111), a second node (112), and a third node (113) as shown. A pulley 115 is disposed at each node so that the wire 118 can extend via the pulley 115. Each node may be an axis of the pulley 115. The traction hook 117 may be located below the pulley 115 disposed at the second node 112.

As described above, the first node 111 of the two-bar link unit 110a is fixed to the horizontal guide bar 114, and the second node 112 slides along the horizontal guide bar 114. The second node 112 (i.e., the axis of the pulley) may be slidably coupled to the long hole 114a. Therefore, the second node 112 can be moved in parallel on the horizontal guide bar 114 along the long hole 114a as shown in FIG. 9.

The third node 113 is located between the first node 111 and the second node 112. The third node 113 may be the central axis along which the second node link portion 110a is folded or unfolded. The gap control cylinder 116 is expanded and contracted with the third node 113 of the two-section link portion 110a between both ends to adjust the degree of opening of the two-section link portion 110a. As a result, the two-section link portion 110a can be widened as shown in FIG. 8 or folded by being closed as shown in FIG. 9.

The position of the gap control cylinder 116 may refer to the operation diagram of FIG. 10. Referring to (a) of FIG. 10, the gap control cylinder 116 may be disposed at both ends with the third node 113 in between. The body and piston of the interval control cylinder 116 may be fixed to both sides of the two-node link portion 110a with the third node 113 in between. Each anchor point may be formed as a hinge. Therefore, the gap between the fixed points can be increased by expanding the piston to adjust the degree of opening of the two-section link part (110a), and the gap control cylinder 116 has a two-section link part (110a) due to the hinge structure of the fixed point. It can maintain its posture even when folded.

When the gap control cylinder 116 is driven, the variable crane module 110 moves the tow hook 117 into and out of the lifting frame 10 through parallel movement of the second node 112. As described above, the tow hook 117 and wire 118 can be passed inside the lifting frame through a cut or groove that overlaps the variable crane module 110. Therefore, when the variable crane module 110 is folded, the towing hook 117 is retracted into the lifting frame 10 as shown in FIG. 9.

With this structure, among the above-described assembly steps (S200 to S300), especially the step (S300) of inserting the other frame block 20 into the lifting frame 10 (step (c) - see (a) of Figure 12). In, the variable crane module 110 horizontally moves the tow hook 117 inside the lifting frame 10 as shown in FIGS. 8 and 9, and lifts the lifting frame 10 without changing the height of the other frame blocks 20. It is possible to introduce another frame block 20 into the lifting frame 10 through the side (i.e., passage 11 on the side).

By horizontal movement, the frame block 20 is supplied into the lifting frame 10 in the shortest route through the passage 11 on the side of the lifting frame 10, thereby speeding up the process. In addition, if the frame block 20 is pulled in while maintaining a horizontal state, there is no vertical fluctuation of the load during the pull-in process, so the load on the winch 41 in the process can be reduced. This process may be practically impossible if the frame block is towed by a separate external crane.

In addition, the gap control cylinder 116 adjusts the horizontal position of the second node 112 when pulling the frame block 20 to pull the point of application of the load acting between the first node 111 and the second node 112. It can also be overlapped with the jack module 210. That is, by changing the length of the gap control cylinder 116, the point of application of the load can be moved toward the towing jack module 210, which is the fixed point, to distribute the load and maintain balance.

For example, referring to (a) of FIG. 11, when the frame block 20 is towed with the towing hook 117, a substantial fixing point may be formed in the towing jack module 210. During installation of the high-altitude lifting device, the above-described towing jack module 210 is coupled to the lifting frame 10 to adjust the position of the lifting frame 10, so that the lifting frame 10 is fixed to the unit rail 30. The towing jack module 210 can act as a fixation point.

At this time, torque is applied to both sides of the towing jack module 210 by the distribution of the center of gravity of the frame block 20 and the lifting frame 10 (e.g., the lifting frame is divided by the gap between the center of gravity of the frame block and the towing jack module). A torque acting on the outside and a torque acting on the inside of the lifting frame due to the gap between the center of gravity of the lifting frame and the towing jack module) may be generated. By adjusting the gap using the gap control cylinder 116, this torque can be adjusted to achieve balance. That is, by moving the frame block 20 horizontally, the distribution of the center of gravity can be changed and a substantial load can be transmitted to the towing jack module 210.

In this way, the installation process of the high-altitude lifting device can be performed more efficiently by the horizontal movement structure of the variable crane module 110.

Meanwhile, referring to FIG. 8, the towing jack module 210 can be detachably coupled to the lower part of the lifting frame 10. For example, the towing jack module 210 can be coupled to the bottom of the lifting frame 10 by a coupling method such as bolting or a coupling method using a pin. Since the lifting frame 10 is composed of multiple frames, the towing jack module 210 can be fixed to the lifting frame 10 by appropriately utilizing the frame structure.

The illustrated towing jack module 210 is a view of the above-mentioned towing jack device from the rear side, and a support member for fixing the pair of the above-described first adjustment cylinders so as not to spread is disposed on the outside. The support can also be used as a detachable structure that is attached to and detached from the lifting frame (10). However, this is just an example and the shape or structure may be modified as needed, so there is no need to limit understanding to the drawings.

The lifting frame 10 surrounds the frame block 20 and is formed by stacking one frame block 20 and a portion of another frame block 20 to form a square frame having an acceptable length in the vertical direction. . A roller support 16 in rolling contact with the frame block 20 can be placed inside the lifting frame 10, and the movement of the lifting frame 10 can be made more stable by the roller support 16.

For example, a plurality of roller supports 16 can be placed on the opposite side of the towing jack module 210 in the lifting frame 10 or at upper and lower positions of the towing jack module 210.

Meanwhile, a plurality of coupling holes 21 may be formed at the top and bottom of the frame block 20 as shown. By inserting the connecting bar 22 into the coupling hole 21, the frame blocks 20 can be connected in a vertically stacked manner. The connecting bar 22 can also be fixed by pin coupling or bolting coupling after insertion. The variable crane module, lifting frame, and frame block of the present invention can be advantageous when self-installed due to this structure.

Based on this structure, the installation method of the above-described high-altitude lifting device will be described in more detail with reference to FIGS. 10 to 13 as follows.

Figure 10 is an operational diagram showing the process of placing the first frame block in the lifting frame, and Figure 11 is a process in which the lifting frame, towing the other frame blocks, rises along the unit rail while one frame block is placed in the lifting frame. It is an operation diagram showing, Figure 12 is an operation diagram showing the process of inserting another frame block into the elevating frame and assembling one frame block with another frame block inside the elevating frame, and FIG. 13 is an operation diagram showing the process of assembling the nth frame block. This is an operation diagram showing the process of placing the lifting frame on the top of the completed frame tower.

First, referring to FIG. 10, the lifting frame 10 is initially placed on the ground or a base 40 located on the ground. In this way, with the lifting frame 10 located on the ground and empty inside, any one of the n frame blocks is towed by the variable crane module 110 and placed inside the lifting frame 10 (S100) [FIG. 10 (a)~(c)].

Through this process, the lifting frame 10 can be brought into a state where it can be raised along the internal frame block 20. The towing jack module 210 can be coupled to the lifting frame 10 after placing the first frame block 20 inside the lifting frame 10. The jacks of the towing jack module 210 (the above-mentioned upper jack and lower jack) are coupled to the unit rail 30 of the frame block 20.

Afterwards, as shown in (d) of FIG. 10, with one frame block 20 placed inside the lifting frame 10, the other frame block 20 is towed by the variable crane module 110 (S200),

Thereafter, as shown in (a) and (b) of Figure 11, the lifting frame 10 is vertically moved along the unit rail 30 formed on the inner one frame block 20, so that the lower end of the lifting frame 10 is connected to the inner one frame. Raise the block 20 to the top (S300),

Afterwards, the lifting frame 10 is fixed as shown in (a) of Figure 12, and the other frame block 20, which has been newly towed by the variable crane module 110, is introduced into the lifting frame 10, as shown in Figure 12 (b). As shown, inside the lifting frame 10, the lower end of another frame block 20 is connected to the upper end of one frame block 20 and stacked (S400).

These steps can be repeated until all n frame blocks are assembled.

That is, the other frame blocks 20 on the outside of the lifting frame 10 are newly towed and the lifting frame 10 is raised along the frame block 20 already placed inside the lifting frame 10 to empty the inside of the lifting frame. there is. Therefore, the towed frame blocks 20 can be directly inserted into the lifting frame 10 through horizontal movement and stacked inside the lifting frame. By repeating this process, the lifting frame 10 is raised step by step, and the number of frame blocks 20 stacked at the bottom increases. Through this, a frame tower of the desired height can be formed.

At this time, each time the frame block 20 is towed, the horizontal position of the second node 112 of the variable crane module 110 is adjusted with the gap control cylinder 116 as described above to adjust the point of application of the load to the towing jack module ( 210) can be overlapped. Therefore, repeated processes can be performed stably while maintaining the balance of the entire device.

In addition, as described above, the variable crane module 110 moves the tow hook 117 horizontally into the lifting frame 10 without changing the height, and enters the lifting frame 10 through the side of the lifting frame 10. Therefore, the frame block 20 is supplied through the shortest possible path, so the process can proceed quickly.

In addition, when the frame block 20 is pulled in in the horizontal direction like this, there is no vertical fluctuation of the load during the pull-in process, so the load on the winch 41 in the process can be effectively reduced.

At this time, as shown in (b) of FIG. 12, the lower end of the other frame block 20 and the upper end of the frame block 20 introduced earlier can be connected via the above-described connecting bar (see 22 in FIG. 8). . The joining positions of both sides within the lifting frame 10 can be adjusted appropriately.

This assembly process (S200 to S400) can be repeated to form a frame tower 20-1 in which all n frame blocks 20 are stacked, as shown in FIG. 13. That is, the assembly of the frame blocks is repeated in the above manner, and finally, the nth frame block 20 is connected to the top of the n-1th frame block 20 that was introduced first inside the lifting frame 10 to form the frame tower 20- 1) can be completed. When the frame tower 20-1 is completed through this, the lifting frame 10 is lowered along the unit rail 30 of the n-1th frame block 20 as shown in (b) of Figure 13, and the frame tower 20 -1) Place it on the top (S500).

The lifting frame 10 has a downwardly protruding engaging protrusion (see 14 in FIG. 8) formed at the top, so that it can be coupled to the engaging hole (see 21 in FIG. 8) of the frame block 20. When the lifting frame is coupled to the frame tower and the lifting frame 10 is seated, the lifting frame is fixed, and there is no need to support the lifting frame 10 with the towing jack module 210. Therefore, the towing jack module 210 can be separated from the lifting frame 10 and placed on the vertical rail portion 30-1.

That is, after the lifting frame 10 is seated on the top of the frame tower 20-1, the towing jack module 210 detachably coupled to the lifting frame 10 is attached to the lifting frame 10 as shown in (b) of Figure 13. ) can be separated from the frame tower (20-1) and movably placed on the vertical rail portion (30-1) arranged along the frame tower (20-1). In this way, by placing the towing jack module on the vertical rail, it is possible to prepare for lifting heavy objects as soon as the installation of the high-altitude lifting device is completed.

In this way, the above-described high-altitude lifting device (see 1 in FIG. 1) can be installed completely independently without the help of separate lifting equipment. If you want to dismantle the device, you can reverse the process described above and quickly dismantle without the help of other equipment. In this way, a high-altitude lifting device can be installed.

Although embodiments of the present invention have been described above with reference to the attached drawings, those skilled in the art will understand that the present invention can be implemented in other specific forms without changing its technical idea or essential features. You will be able to understand it. Therefore, the embodiments described above should be understood in all respects as illustrative and not restrictive.
