A flat car for railway transportation

Abstract

The invention relates to an open wagon fused for rail transportation. A wagon body comprises a head wall, a side wall and an underframe; side posts of the open wagon are profiling side posts and adopt a built-in structure; a floor adopts profiling heaves to give a way to an open-wagon body structure of wheels. The invention has the technical proposal that the profiling side posts are distributed inside the side wall and directly connected with the upper covering plates of a beam and a corbel, thereby not only increasing the capacity of the wagon body, but also increasing the intensity of the side wall; the cross section of the profiling side post and the side wall form a certain angel, thereby being convenient for a car dumper to unload; the root of the profiling side post is made of arc reinforcing plate, thereby not only protecting the welding seam between the side post and the upper covering plates of a beam and a corbel, but also increasing the intensity of the root of the side post and reducing the corrosion of the root of the side post; the floor also adopts a profiling structure, and the floor is raised at the position of wheels, thereby reducing the height of the wagon floor and the height of the entire gravity center, and improving the driving stability of the open wagons; the outside of the side wall is relatively flat and smooth, thereby reducing the driving resistance of open wagons and improving the driving stability of the open wagons.

Description

technical field [0001] The invention relates to a railway transportation vehicle, in particular to an open car for railway transportation of ore, which belongs to the field of railway transportation equipment. Background technique [0002] There are mainly two types of freight wagons on the railway: box wagons and gondola wagons, and some special vehicles (such as tank wagons, flat wagons, etc.). The traditional railway open car body is composed of end walls, side walls, and underframes. The side columns are distributed on the outside of the side walls, and the floor is flat. The railway open car with this structure has a large axle load and large wheels. Disadvantages: First, the volume of the vehicle body cannot be maximized, and the limit cannot be fully utilized to maximize the load of the vehicle; second, the center of gravity of the vehicle is too high, which reduces the stability of the vehicle's operation. However, with the increase of logistics and the fierce compe...
