Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a platform for a railway vehicle.

[Conventional technology]

Conventionally, as shown in FIGS. 3 and 4, a platform work for a railway vehicle has a middle burr 1.1 disposed in the longitudinal direction in the center,
A plurality of horizontal burrs 3.3 are arranged in a direction orthogonal to the middle burr 1 and the side burrs 2 between the side burrs 2.2 arranged on both sides parallel to the middle burr 1.1. It consisted of 4 vehicle inspection burrs placed between 1.1 and 1.

[Problem that the invention seeks to solve]

However, in the case of such a structure, the horizontal burrs are separated by the middle burrs, so the side burrs bear most of the compressive load and vertical load at the end of the car, so a strong burr is required, which poses an obstacle to reducing the weight of the car body. It had become.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a platform workpiece in which the weight of the vehicle body is reduced by placing the load on the center burr and the lateral burr.

Means for Solving Problem C] To achieve the above object, the present invention provides a middle burr arranged in the longitudinal direction of the central part, and sides arranged in the longitudinal direction of the left and right ends parallel to the middle burr. In a railway vehicle platform work in which a plurality of horizontal burrs are arranged in a direction perpendicular to the burrs, the lateral burrs contact the upper surface of the middle burr, the upper horizontal burr contacts the inner surfaces of both side burrs, and the lower surface of the middle burr. and a lower horizontal burr that abuts the inner surfaces of the burrs on both sides.

〔Example〕

Hereinafter, one embodiment of the present invention will be described based on FIGS. 1 and 2.

A middle burr 11 is arranged at the center in the longitudinal direction of the workpiece 10, and side burrs 12 and 12 are arranged parallel to the left and right sides of the middle burr 11.
are arranged, and their front and rear ends are connected with a burr 13, 13, respectively.

On the upper surface of the middle burr 11, the upper horizontal burr 14 contacts the upper surface of the middle burr 11 with its center part 14a in the direction orthogonal to the middle burr 11, and contacts the inner surface 12 of the side burr 12.12 with both ends 14b, 14b.
a, 12a, respectively, and a lower horizontal burr 15 is provided on the lower surface of the middle burr 11, with the center part 15a contacting the lower surface of the middle burr 11 in a direction perpendicular to the middle burr 11, and both ends 1
5b, 15b on the inner surfaces 12b, 12 of the side burrs 12.12.
A plurality of them are arranged in contact with each other.

Note that 16 is a pillow burr that supports the cart 17.

With this configuration, the middle burr 11 mainly bears the car end compressive load, and the upper lateral burr 14 and the lower lateral burr 15 bear the vertical load, respectively, but since both are made of continuous members, efficiency is improved. It is possible to reduce the weight of the car body,
Furthermore, since each member is made up of continuous members, the number of joints between each member is reduced, and workability and assembly accuracy are improved.

〔Effect of the invention〕

As described above, the present invention includes a plurality of horizontal burrs in a direction perpendicular to the middle burr arranged in the longitudinal direction of the central part and the side burrs arranged parallel to the middle burr in the longitudinal direction of the left and right ends. In a platform work for a railway vehicle in which the horizontal burr is arranged, an upper lateral burr contacts the upper surface of the middle burr and abuts the inner surfaces of the burrs on both sides, and a lower lateral burr contacts the lower surface of the middle burr and abuts the inner surfaces of the burrs on both sides. Since it is composed of burrs, both the middle burr and the lateral burr become a continuous member, which is very advantageous in bearing the load, making it possible to reduce the car body to pumice, and also improving the workability of assembling each part. .
