Side wall supporting structure and hopper car

Abstract

The invention discloses a side wall supporting structure and a hopper car. The side wall comprises a connecting beam and two supporting units; each supporting unit comprises a side wall supporting plate and a reinforced beam fixed to one side of the side wall supporting plate; the edge of the side wall supporting plate far away from the reinforced beam is in an arc shape matched with the inside radian of the side wall plate; the reinforced beams of the two supporting units are connected by the connecting beam; and the two side wall supporting plates are spaced by a certain distance. Many defects in the prior art are overcome and the advantages of reducing the self weight and improving the space utilization rate and the reliability are realized.

Description

technical field [0001] The invention relates to the technical field of railway hopper cars, in particular to a side wall support structure and a hopper car. Background technique [0002] The side wall of the railway transport hopper car is divided into two types: the straight side wall and the arc-clad side wall. In order to improve the rigidity of the arc-clad side wall, a group is generally installed or multiple sets of support structures. [0003] The side wall supporting structure of the existing hopper car is as follows: figure 1 and figure 2 As shown, it is formed by overlapping welding of two side wall support plates 2, and the edges of the two side wall support plates 2 away from the welding place are respectively welded to the inner wall of the side wall plate 1; the lower part of the side wall support plate 2 is welded and fixed on the funnel On the back 7 of the underframe, the top is welded with the roof panel 3 of the funnel car or the reinforcing plate 8, a...

AI Technical Summary

Problems solved by technology

[0004] 1. The side wall support plate 2 has a large area, resulting in a large self-weight;

[0005] 2. When loading bulk cargo, due to the large area of ​​the side wall support plate 2, the fluidity of the bulk cargo is poor. When the hopper car produces a longitudinal impulse, most of the longitudinal impact force of the bulk cargo acts on the side wall support plate 2 As a result, the side wall support plate 2 is subjected to a large longitudinal force, which reduces the reliability of the side wall plate 1 and the side wall support plate 2;

[0006] 3. Due to the problem of the angle of repose of the bulk cargo, when the leaky warehouse is used for mechanized loading, there must be empty space where the cargo cannot be loaded.

The side wall support plate 2 divides the entire loading space in the car into several independent spaces, and each independent space has a part of empty space, which reduces the available space in the hopper car and reduces the space utilization rate
