Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a method for manufacturing a side structure of a railway vehicle.

[0002]

2. Description of the Related Art As shown in FIG. 9, for example, a side structure of a railway car is provided with an outer plate composed of a curtain plate 2, a blow plate 3 and a waist plate 4 on a frame 1 for one car. It is manufactured by attaching and then attaching the entrance frame 5.

[0003]

However, since the above-mentioned curtain plate is a thin plate of about 20 m in length corresponding to the entire length of the vehicle, it is troublesome to handle. is there. Further, since the curtain plate is continuous over the entire length of the vehicle, the position of the outer plate seam at the lower portion of the curtain plate comes at a height near the upper end of the entrance frame. The maximum value of the shaku dimension 1524
mm, it must be divided into a blow plate and a waist plate, and the outer plate is divided into a curtain plate, a blow plate and a waist plate, and two rows of seams are spot-welded. Furthermore, when viewed from the side, the railcar is formed in a bow shape with the center portion of the vehicle body slightly lifted up from the end of the car, so that a slightly arch-shaped warpage called a camber is attached to the side structure. However, since the curtain plate is continuous throughout, it is somehow processed, but it is not an easy task. Further, even if the accuracy of the completed dimension in the longitudinal direction of the vehicle is improved, there is no adjustment allowance when the curtain plate is continuous. Moreover, 1
Since a frame for both parts is assembled, and then a skin is attached, a large work space is required, and the space is limited.

Accordingly, an object of the present invention is to provide a method for manufacturing a side structure of a railway vehicle in which the work of attaching an outer plate is facilitated to improve work efficiency and reduce costs.

[0005]

In order to achieve the above-mentioned object, the present invention relates to a method for manufacturing a side structure of a railway vehicle in which an outer plate is attached to a skeleton and an entrance frame is attached thereto. It is characterized in that a side entrance block in which a bone member is attached to an entrance frame plate including a window block and a curtain plate portion attached to the above is individually formed, and each block is welded and joined.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below based on an embodiment shown in the drawings. The side structure is configured by joining two sets of vehicle end window blocks 10, two sets of intermediate window blocks 20, and three sets of side entrance blocks 30. Each of the vehicle end window blocks 10 disposed in front and rear of the vehicle body is formed by attaching an outer plate 12 including a curtain plate portion to a skeleton 11, and the skeleton 11 includes a corner post 11a, a door end post 11b, and a door pocket outer post. 11
The vertical bone member c is connected to the horizontal bone members of the curtain band member 11d, the waistband member 11e, and the long base member 11f, and the vertical bone members of the hip bone 11g and the curtain bone 11h are connected above and below the window opening. ing. The outer panel 12 includes an upper panel 12a and a lower panel 1.
2b and the upper shell 12
a forms a window opening 12c and is attached to the upper part from the waistband member 11e, that is, to the conventional curtain plate portion and the blow-by plate portion, and the lower outer plate 12b is attached to the conventional waistboard portion. Further, an outer plate reinforcing bone 13 is attached to the inner side between the bones of the outer plate 12 and to the upper part of the curtain band member 11d.

Each intermediate window block 20 is formed by attaching an outer plate 22 including a curtain plate portion to a skeleton 21. The skeleton 21 is attached to four side pillars 21a, which are vertical frame members, by a curtain band member. 21b, the waistband member 21c, and the horizontal bone member of the long base member 21d are connected, and the waistbone 21e and the tabular bone 2
It is constituted by connecting the vertical bone members 1f. Outer plate 22
Is composed of an upper outer plate 22a and a lower outer plate 22b larger than the frame 21, and the upper outer plate 22a is
c is formed on the waistband member 21c and attached to the upper curtain plate portion and the blowing plate portion, and the lower outer plate 12b is attached to the waistboard portion. In addition, the inside between each bone of the outer plate 22 and the curtain band member 21
An outer plate reinforcing bone 23 is attached to the upper part of b.

In the side entrance block 30, an entrance frame plate 31 including a curtain plate portion is composed of an upper frame member 31a, a lower frame member 31b and side frame members 31c, 31c, and an entrance opening 31d.
The upper frame member 31a of the entrance frame plate 31
It is formed by attaching a long girder member 32a and a curtain band member 32b as a bone member on the back surface, and attaching a fuzzy receptacle 32c as a bone member on the back surface of the lower frame member 31b.

[0009] As described above, each of the 2 individually created
A set of vehicle end window blocks 10, two sets of intermediate window blocks 20, and three sets of side entrance blocks 30 are welded and joined to complete a side structure. That is, as shown in FIG. 1, each side entrance block 30 is welded between the car end window block 10, the middle window block 20, the middle window block 20, and the car end window block 10 arranged at predetermined intervals.

Each side entrance block 30 includes an outer surface of the outer plate 12 of the vehicle end window block 10 and an outer plate 22 of the intermediate window block 20.
The frame plate 31 is overlapped on the outer surface and spot-welded. At this time, the lower margin of the frame plate 31 is only 1 to 2 compared to the upper margin.
mm wide. As a result, the lower side edge of the side entrance block 30 in the center of the vehicle body is slightly raised above the lower edge of the vehicle end portion of the vehicle end window block 10 so as to be formed in an arc shape, and the side structure is provided with the camber. Become.

As described above, since the vehicle end window block 10, the intermediate window block 20, and the side entrance block 30 are individually formed, the size in the longitudinal direction is reduced, and the handling of the outer plate is facilitated. In addition, since the outer plate is attached to each block instead of continuing the curtain plate over the entire side structure as in the conventional case, the outer plate can be processed within the maximum standard dimension of a stainless steel plate. Thus, by reducing the number of seams of the outer plate to one, processing, welding, sealing man-hours, etc. of the shape of the seam are reduced, and the cost is reduced. Further, if the seam position is divided, for example, by a window, the cost can be further reduced.

In addition, since the blocks are individually assembled, the assembling work of each block can be performed at a place having a length of about 3 to 5 m, and the storage after the assembly can be performed at the same place. For this reason, it is possible to manufacture even smaller equipment than before and transport is also possible, so that each block can be outsourced, and if the blocks are manufactured in parallel, the construction period can be shortened. In addition, since the blocks are arranged and joined at the time of the final assembly, an outer plate consisting of a curtain plate, a blower plate, and a waist plate is pasted on the conventional one-frame structure, and then compared to a method of attaching an entrance frame. The working time is simplified and shortened. In addition, a space having a length of about 20 m is required at the time of final assembly, but the occupation time of the final assembly site is shortened by shortening the working time. Also, as described above, by making the overlap margin of each block slightly wider at the lower part than at the upper part,
Camber can be easily attached. Furthermore, since there is a margin at the joint between the blocks, a structure with good dimensional accuracy in the longitudinal direction can be manufactured by making adjustments here.
The present invention is not limited to stainless steel and can be applied to iron and aluminum side structures.

[0013]

As described above, in the method for manufacturing a side structure of a railway vehicle according to the present invention, a frame member is attached to a window block in which an outer plate including a curtain plate portion is attached to a frame, and an entrance frame plate including a curtain plate portion. Since the attached side entrance blocks are individually formed and each block is welded and joined, the dimension of the outer plate in the longitudinal direction is reduced, and the handling becomes easy. In addition, since an outer plate is attached to each block, the outer plate can be divided into two parts, and by reducing the number of seams of the outer plate to one, processing, welding, sealing man-hours, etc. of the joint portion are reduced, resulting in cost reduction. . In addition, since each block is individually assembled and each block is joined at the time of final assembly, the assembly work of each block is about 3 to 5 m.
It is possible if there is a place of about the same length, and storage after assembly is also possible in the same place. For this reason, it is possible to manufacture even smaller equipment than before and transport is possible, so that each block can be outsourced, and if the blocks are manufactured in parallel, the construction period can be shortened. In addition, although a place having a length of about 20 m is required at the time of final assembly, the work time can be greatly reduced as compared with the related art, so that the occupation time of the final assembly place is shortened. Further, as described above, the camber can be easily attached by making the overlap margin of each block slightly larger at the lower part than at the upper part. Furthermore, since there is a margin at the joint between the blocks, a structure with good dimensional accuracy in the longitudinal direction can be made by making adjustments here.
