Gondola car for railway and bottom support structure thereof

Abstract

The invention discloses a gondola car for a railway and a bottom support structure thereof. The structure includes a frame body and a floor. The frame body includes a mid-beam assembly extending in the length direction of the gondola car of the railway, a cross-beam assembly vertically mounted on the mid-beam assembly, end-beam assemblies mounted at the two ends of the mid-beam assembly, and the connection portions of the mid-beam assembly, the cross-beam assembly and the end-beam assemblies are welded and fixed; the floor is fixedly connected with the frame body, and the portions, corresponding to wheels of the gondola car for the railway, of the floor are provided with avoidance structures. In this way, the bottom support structure adopts the frame body formed by connecting multiple horizontally arranged beam bodies with multiple vertically arranged beam bodies through welding, the avoidance structures are designed on a bottom plate, thus the self weight of a vehicle can be reduced,the interference and friction between bogie wheels and the iron floor can be reduced to the greatest extent, and the gondola car has the advantages that the self weight of the vehicle is small, the load is large, and the structure is simple, safe and reliable.

Description

technical field [0001] The invention belongs to the technical field of railway freight transport, and in particular relates to a railway gondola car and its bottom supporting structure. Background technique [0002] The open railway car is a railway transportation equipment used to transport bulk goods such as coal, ore, ore powder, iron filings and steel slag. At present, in order to achieve the weight reduction effect of the vehicle's own weight without weakening the strength of the vehicle, it is generally achieved by local reinforcement or the use of metals with low density instead of traditional carbon steel to achieve the weight reduction effect of the vehicle, which makes the vehicle exist. The structure is complex, the manufacturing cost is increased, the production efficiency is not high, and the reliability of the accessories is not high. At the same time, since the height between the iron floor and the rail surface of the vehicle is fixed, when the vehicle is tra...

AI Technical Summary

Problems solved by technology

At present, in order to reduce the weight of the vehicle without weakening the strength of the vehicle, it is generally achieved by local reinforcement or the use of metals with low density instead of traditional carbon steel to achieve the effect of vehicle weight reduction. Disadvantages such as complex structure, increased manufacturing cost, low production efficiency and low reliability of accessories

At the same time, since the height between the iron floor and the rail surface of the vehicle is fixed, when the vehicle is transporting some high-density goods, loaders or forklifts are used to load them from the top of the vehicle, and the falling of the goods will cause crushing on the iron floor of the vehicle. Damage to the iron floor will cause deformation of the iron floor, so that the wheels of the bogie will interfere with the iron floor during the operation of the vehicle, resulting in driving safety and damage to the vehicle
