Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for assembling a railroad vehicle such as a Shinkansen, especially for a leading portion (or a rearward portion), and a railway vehicle related thereto.

[0002]

2. Description of the Related Art FIG. 7 (b) is a perspective view of a conventional high-speed vehicle 1 ', such as a Shinkansen vehicle, showing a part of a leading portion (or a trailing portion) in a see-through manner. A head structure 4 'is covered on an underframe 2' having wheels and a driving device (not shown) at a lower portion, and the inside thereof, that is, a space surrounded by the underframe 2 'and the head structure 4'. The cab (cab console and control equipment necessary for operation) 1 shown in FIG.
0 'is arranged.

[0003] Conventionally, as shown in FIG.
The cab 10 'is installed after the top structure 4' is assembled on the top. Conventionally, in order to construct the structure 4 'formed by attaching a similar metal plate 4b' to the outside of a metal frame 4a 'made of an aluminum alloy or the like, the inside, that is, the cab 1
This is because work from the space side in the vehicle compartment where the 0 'should be installed was required. In other words, in order to manufacture a streamlined structure 4 'as shown in the figure in which the running resistance due to wind pressure is small, the frame 4a' is assembled first, and the plate 4b 'is applied to the outside, and the plate 4b' is applied from the inside and the outside. The cab 10 'cannot be installed first because the work is performed such that the shape is adjusted along the frame 4a' by sheet metal processing and the like, and the two are integrated by welding from the inside. It was. The top structure of commuter trains is not streamlined, so there is no need for sheet metal processing from inside or outside, but the assembly of the top structure on the underframe has also been completed in accordance with the procedure for high-speed vehicles. A cab was installed later.

[0004]

The conventional assembling method for the leading portion of a railway vehicle shown in FIG. 7 has the following problems.

[0005] A) Since the cab 10 ′ is installed on the underframe 2 ′ after the head structure 4 ′ is assembled, the console and other devices of the cab 10 ′ are divided into small parts at the time of installation. Must be carried into the passenger compartment (that is, the portion on the underframe 2 'and surrounded by the structure 4'). In a state in which the head structure 4 'is assembled to the underframe 2', the carry-in path of the cab 10 'is located at a door (entrance) 10a' and a window (a glass is not yet inserted) in the structure 10 '. Only the path shown by the arrow x or y in the example of FIG. 1B can be secured, so that the divided pieces of the cab 10 'must be considerably small. Therefore, the driver's cab 10 'needs to be divided into small devices and units that are easy to assemble. That is, the driver's cab 10 'must be constituted by a greater number of members than necessary for its original function, and it is necessary to secure dimensional accuracy for coupling between members so that subsequent assembly is easy. This requires considerable cost.

(B) The assembling of the driver's cab 10 'to be carried in a divided state must be performed in a narrow cabin surrounded by the head structure 4'. Since the leading end structure 4 'assembled on the underframe 2' surrounds the cab 10 ', the space for assembling the cab 10' is considerably narrow. And the above a)
The cab 10 'is divided into a number of rather small components. Therefore, the driver's cab 1
The work to install 0 'is not easy, and requires considerable labor and cost.

C) When the driver's cab 10 'is assembled and installed in the passenger compartment, the surrounding area (outside) is covered by the head structure 4'. It can be performed only from the inside of 10 '(that is, the side that becomes the interior of the passenger compartment). Operations such as connecting external wiring and piping for the cab 10 'are also performed in this manner.
It is performed from inside 0 '. The cab 1
When work is performed only from the inside of 0 ', some work may not be easily performed, and it is difficult to speed up the assembly of the vehicle by performing many works at the same time in parallel.

An object of the present invention is to provide means for solving the above-mentioned problems, such as facilitating installation of a cab.

[0009]

According to a first aspect of the present invention, there is provided a method for assembling a railway vehicle, comprising: A cab (cab console and various other control equipment necessary for operation) is installed on the frame (having a drive unit at the bottom) before assembling the head structure (skin covering the cabin). And

This assembling method according to the first aspect has the following operation. A) Since the cab is installed on the underframe in which the head structure is not yet assembled, the cab can be carried into the underframe from anywhere in front, rear, left, right and above. As long as such loading is possible, the cab does not need to be divided in advance for loading. Therefore, the driver's cab does not need to be configured in consideration of the ease of later assembly, and can be configured at low cost by a small number of easily manufactured units consisting only of members necessary for the original function.

B) Since the cab can be carried into the underframe from above, it is possible to adopt the simplest carrying method of lifting and carrying the cab with a crane or the like. In addition, since the number of divisions of the cab can be minimized as described above, the operation of connecting the components of the cab after carrying in is unnecessary or hardly required. That is, according to this assembling method, work and cost required for installation of the driver's cab are extremely small.

C) The work after installing the cab can be performed simultaneously from inside and outside the cab and the like.
Since the periphery of the cab or the like is open on the underframe before the structure is assembled, for example, wiring and connecting / fixing pipes to the cab or other on-board equipment may be performed outside the cab (outside the cabin). ), And checking of control devices can be performed from the inside of the cab. Therefore, various operations (for example, construction of a large-sized pipe) can be easily performed, and assembly of the vehicle can be greatly accelerated by performing a plurality of operations simultaneously. In addition, since the operation of assembling the driver's cab, which was conventionally performed on the underframe after the formation of the underframe, can be performed at another portion (such as an electrical appliance factory) during the underframe construction, in that sense, Simultaneous execution of a plurality of operations makes vehicle production more efficient.

According to a second aspect of the present invention, there is provided a method for assembling a railway vehicle.
In particular, in the method of claim 1, for the cab,
Before installing on the underframe, install the equipment so that maintenance from the inside (the side that will be the vehicle interior) is possible,
After installation on the underframe and before assembling the head structure on the underframe, a piping operation and a wiring operation are performed from the outside (the side outside the vehicle compartment). In other words, install equipment inside the cab so that maintenance from the inside is possible, install the cab on the underframe, perform piping and wiring work from the outside of the cab, cover the cab etc. The vehicle is assembled in the order of assembling the head structure on the underframe as described above.

According to such an assembling method, the driver's cab is installed on the underframe before assembling the head structure (as described above).
The functions of a) to c) are performed. After installing the cab and before assembling the structure, the piping and wiring work is performed from the outside of the cab (described above), so that the vehicle assembly is speeded up by performing a plurality of operations simultaneously (see c) above).

According to the second aspect of the present invention, since the equipment is installed in the cab so that maintenance can be performed from the inside (as described above), after the head structure is assembled (for example, after the vehicle is completed). The maintenance of the equipment in the cab is also possible. If the equipment was not able to be maintained from the inside by installing the equipment from the outside as well as the wiring and piping work (above) performed from the outside of the cab, complete the vehicle When performing maintenance on the device later, it is necessary to remove the head structure. In the case of claim 2, there is no such inconvenience.

The method according to the second aspect is characterized in that such a device is incorporated into a cab before being installed on a frame. By doing so, a cab having necessary equipment therein can be completed (or almost completed) in a specialized factory (for example, a control device manufacturing factory), and the cab installed on the underframe can be completed. As compared with the case where devices are incorporated, the production of the driver's cab can be accelerated, and the cost can be reduced. Carrying in the cab on the underframe can be easily performed as described above regardless of the size and weight of the cab, so that there is no inconvenience even if devices are previously installed in the cab as described above. I can say.

According to a third aspect of the present invention, the leading vehicle body is made of a plastic molded article such as FRP, and the driver's cab is fixed to the underframe of the leading vehicle body without being supported by the body. It is characterized by doing.

The front structure of the railway vehicle is FRP
This is different from the structure illustrated in FIG. 7 in which a metal plate is attached to the outside of a metal frame. That is, since it is a molded product that is formed into a predetermined shape in advance using a predetermined molding die or curing means (that is, before being transported onto the underframe), when assembling the product onto the underframe, cover the product. Thus, it is only necessary to mount the components on the underframe and join them together, and there is no need to perform work from the inside of the vehicle compartment such as sheet metal working or welding. Also, in this railway vehicle, the driver's cab is installed by fixing it only to the underframe (or a support fixed on the underframe) at the top of the vehicle, and the top structure which is a molded product such as FRP is installed. Do not support. Therefore, when installing the cab, there is no reason that the head structure must already be assembled on the underframe.

Therefore, with regard to this railway vehicle, it is possible to install the cab on the underframe before assembling the head structure on the underframe, and the assembling method of claim 1 can be implemented. it can. If the assembling method of the first aspect can be carried out, the vehicle can be rationally manufactured by the above-mentioned operations a), b) and c).

According to a fourth aspect of the present invention, in the vehicle of the third aspect, piping and wiring for the cab are arranged outside the cab, and equipment requiring maintenance, which is located inside the cab, is provided. It is characterized in that it is arranged at a position where it can be handled from the inside.

[0021] In this railway vehicle, the equipment in the cab can be easily maintained even after the vehicle is completed because the equipment requiring maintenance is arranged at a position where it can be handled from the inside. Also, since the pipes and wiring are placed outside the cab, when the cab is installed on the underframe before the head structure is assembled, the wiring and piping connections and
The assembly of the vehicle can be speeded up by performing a plurality of operations at the same time, such as checking the control devices and the like from the inside of the cab while fixing and the like from the outside of the cab.

According to a fifth aspect of the present invention, there is further provided a railway vehicle, wherein a gap between the driver's cab and the head structure is closed by a rubber tube or the like filled with a fluid (which is a fluid at the time of filling). I do. The fluid to be filled is preferably a fluid that maintains elasticity in a rubber tube, such as air or urethane foam.

The head structure, which is a plastic molded product,
It is easily deformed during manufacturing due to distortion during molding or curing, and it is not easy to correct the deformation later.
Therefore, even if the cab is manufactured with a small dimensional error, it is difficult to make no gap between the cab and the structure. However, when the rubber tube for filling the inside with the fluid is mounted between the cab and the head structure as described above, even if the gap between them is considerably large, it can be closed. The rubber tube swells due to the filling of fluid and increases its thickness, and it is easily deformed based on its own elasticity.Therefore, even if there is a considerable gap between the cab and the structure, the gap is uneven. This is because the gaps are tightly attached to both to eliminate the gap. Eliminating the gaps in this way eliminates the need for a troublesome finishing operation of closing the gaps with eye plates manufactured according to the actual amount of deformation of the structure.

1 to 6 show an embodiment of the present invention. FIG. 1 is a perspective view of a part of the high-speed railway vehicle 1 being manufactured near the head thereof.
(A) shows the head structure 4, and (b) shows the underframe 2 with the cab 10 installed. FIG. 2 is a view of the vehicle 1 shown in FIG.
FIG. 2 is a view of the underframe 2 and the like of the vehicle 1 as viewed obliquely from the front. FIG. 4 is a perspective view of a control device unit 12 which is a part of the cab 10, and FIG. 5 is a perspective view showing a state where a pipe 22 for the cab is attached. FIG. 6 shows the cab 10 holding the rubber tube 30 and the structure 4.
FIG.

The railcar 1 shown in FIG. 1 which is the leading car of the Shinkansen
Generally has a structure in which an underframe 2 having wheels and a driving device (neither is shown) at a lower portion is covered by a head structure 4. A connector (not shown) is provided at a portion forward of the structure 4, and a connector cover 3 is provided above the connector.
Is covered. The underframe 2 has a base plate 2b attached between surrounding side frames 2a as shown in FIG. 2, and a floor material 2c is attached to the upper surface thereof.

In the vehicle 1, the head structure 4 is made of a plastic composite material. As shown in FIG. 7, a metal structure 4 'composed of a frame 4a' and a plate 4b '
In this case, since a considerable amount of man-hour is required for integration between the frame 4a 'and the plate 4b' and finishing of the surface, the purpose is to reduce the number of man-hours by manufacturing the structure from plastic. The composite material for the structure 4 in the vehicle 1 shown in FIG. 1 includes a core (several tens of mm thick) made of a plastic foam material between inner and outer skins (thickness of several mm) made of FRP (fiber reinforced plastic). ) Is used as a plate-like composite material having a sandwich structure (having an overall thickness of about 50 mm). In such a composite material, the inner and outer layer skins mainly have strength against in-plane tension, bending, shearing, etc., and these are combined with the action of a core having a considerable thickness, so that out-of-plane bending, etc. This is because, in order to exhibit rigidity, the required strength can be provided without integrating other frames. In particular, regarding the structure 4, each skin of the inner and outer layers is made of a highly elastic carbon fiber reinforced plastic (CF).
RP), and the core is made of a polymethacrylimide foam material for a heat-resistant structure.

The composite head structure 4 as described above is
A prepreg (not shown), which is a material of the FRP plate, is laminated on a mold (not shown) having a shape along the outer surface shown in FIG. 1 (a), and these are autoclaved (not shown). It is manufactured by heating and pressurizing in the inside to cure. After curing, it is not necessary to add a molding step or the like, and on the underframe 2 of the vehicle 1, the structure 4
You do not need to do any work. Therefore, underframe 2
The assembling of the upper structure 4 is completed only by lowering the formed structure 4 on the underframe 2 by hanging it with a crane (not shown), and connecting the underframe 2 to the underframe 2.

Since the vehicle 1 is the leading vehicle, a driver's cab 10 is disposed inside the structure 4.
The driver's cab 10 is set on the underframe 2 before assembling. That is, as shown in FIGS. 1 to 3, the driver's cab 10 is first installed on the underframe 2, and then the structure 4 is covered from above. If it is performed at a stage without the structure 4, the cab 10
This is because, for example, the work of carrying in and installing on the underframe 2 can be performed very easily. Also, such a procedure can be taken because the structure 4 does not require work from the inner surface side on the underframe 2 as described above, so that the cab 10 or the like is installed on the underframe 2 This is because there is no trouble in the operation even when the assembly is performed. Note that the driver's cab 10 includes the console 11 shown in FIGS. 2 and 3 and the unit 12 shown in FIG.

The assembling work of the railway vehicle 1 including the manufacture and installation of the cab 10 is performed according to the following procedure. That is, the console 11 including the instrument panel 11a, the table 11b, the lower block 11c, the frame 11d, and the like shown in FIG. As shown in FIG. 3, the inside of the console 11 includes control equipment 11e (electric equipment or fluid pressure equipment, etc.) and its supporting member 11f, which are inside the console 11 (the underframe 2 serving as a vehicle compartment). Opening lid 1 on the lower block 11c etc.
1j is provided) so that maintenance is easily performed. Since the control devices 11e are the most important components in function, it is preferable that the console 11 is manufactured in, for example, a factory dedicated to control devices.
It is manufactured before the assembly is completed. The console 1 is used to simplify the installation work on the underframe 2 to be performed later.
For 1, it is preferable to advance the integration as much as possible within a range in which transportation by lifting or the like is possible.

The unit 12 shown in FIG.
Like the console 11 described above, it is manufactured separately from the underframe 2 and the like. This unit 12 has a built-in control device 12c and a connector 12d inside a frame 12a having a caster 12b at the bottom. In the conventional vehicle 1 'shown in FIG. 7, the metal frame 4 of the structure 4'
Although the control devices were individually mounted inside a ′ (not shown), the vehicle 1 shown in FIG. 1 does not include a frame suitable for mounting in the structure 4 and has a large size due to the assembly procedure. Since it is easy to carry in all the devices at once, the control devices 12c and the like are contained in one unit 12 as shown in FIG. The unit 12 is also configured so that maintenance of the control devices 12c can be performed from the inside while being installed on the underframe 2.

Also, separately from the underframe 2 etc., the top part structure 4
To manufacture. Since the manufacture of the structure 4 is completed through the above-described molding and curing steps, it is not necessary to adjust the shape thereafter.

The console 11 manufactured as described above
And the unit 12 are loaded onto the underframe 2 by a crane (not shown) at a vehicle manufacturing factory and installed. At this time, since the structure 4 is not assembled to the underframe 2, such loading and installation can be performed extremely easily. As for the console 11, a high floor frame 2d is constructed on a floor material 2c stretched on the underframe 2 as shown in FIG. 2, and a part of the frame is placed on the high floor frame 2d. Since the structure 4 and the like have not been assembled on the underframe 2, the frame 11 d of the installed console 11 is fixed only to the underframe 2 with bolts 11 g and the like as shown in FIG. 3. In addition, about installation of the unit 12 of FIG.
What is necessary is just to move to an appropriate position on the underframe 2 using the casters 12b and fix the frame 12a and the like on the underframe 2 by some fixing means.

When the installation of the console 11 and the unit 12 is completed, the wiring 21 and the pipe 22 shown in FIG. 3 and the like are connected to them. In the vehicle 1 'of FIG. 7, the wiring is tied to the metal frame 4a' (not shown), but in the vehicle 1 as shown in FIG. 3, it is supported by being tied to the frame 11d of the console 11. Since the pipe 22 cannot be supported by a conventional supporting method such as being supported inside the frame 4a 'in FIG. 7 (not shown), the pipe 22 is supported by the frame 11d of the console 11, or as shown in FIG. The support tool 23 is fixed on the upper side and attached to the outside thereof to be supported. Both the wiring 21 and the pipe 22 are arranged on the outer side of the underframe 2,
It is preferable that the wiring and piping work can be performed outside the cab 10 while checking the control devices and the like from the inside.

When the installation of the cab 10 and the construction of the wiring 21 and the pipe 22 are completed as described above, FIG. 1 or FIG.
The head structure 4 is mounted on the underframe 2 as shown in FIG. That is, the structure 4 formed as described above is suspended by the crane (not shown) on the underframe 2, and the joint 4x of the structure 4 is joined to the bracket 2x of the underframe 2 shown in FIG. Both are fastened from the outside of the underframe 2 with bolts, rivets or the like. It is highly likely that the structure 4 has been deformed in the above-described curing step, and an error occurs when the structure 4 is attached. In order to fill a gap that is likely to be generated between the console 11 due to the deformation or error, a rubber tube 30 shown in FIG. 6 is used as an example in this assembly. That is, a rubber tube 30 is previously attached to appropriate positions on the upper surface and side surfaces of the console 11, and after assembling the structure 4 on the underframe 2, the tube 30 is filled with a fluid such as air to fill the tube 30. Seal. The tube 30 swelled by filling with a fluid has its thickness increased in a portion where the gap between the console 11 and the structure 4 is large, and spreads flat in a portion where the gap is small based on its elasticity and fluid deformability. Thereby, both the console 11 and the structure 4 are brought into close contact with each other, and the gap between them is eliminated.

The head structure, which is a plastic molded product,
It is easily deformed during manufacturing due to distortion during molding or curing, and it is not easy to correct the deformation later.
Therefore, even if the cab is manufactured with a small dimensional error, it is difficult to make no gap between the cab and the structure. However, when the rubber tube for filling the inside with the fluid is mounted between the cab and the head structure as described above, even if the gap between them is considerably large, it can be closed. The rubber tube swells due to the filling of fluid and increases its thickness, and it is easily deformed based on its own elasticity.Therefore, even if there is a considerable gap between the cab and the structure, the gap is uneven. This is because the gaps are tightly attached to both to eliminate the gap. Eliminating the gaps in this way eliminates the need for a troublesome finishing operation of closing the gaps with eye plates manufactured according to the actual amount of deformation of the structure.
