Problems solved by technology

[0002] The side columns of the side wall structure of the existing railway coal hopper car are all set on the outside of the car body. As one of the main load-bearing components of the side wall, the side columns are all made of Large cross-section hollow rectangular tubular structure, and because the side pillars are all set on the outside of the car body, the space between the side pillars cannot be utilized
In addition, the connections between the side columns and the side wall panels are all made by riveting with rivets. On the one hand, the strength of the side wall panels is reduced due to the rivet holes due to the large number of rivets; The situation also increases the weight and cost of the rivet

Embodiment Construction

[0018] see Figure 1-Figure 7 As shown, the side wall structure of the railway coal hopper car provided by the embodiment of the present invention includes: an integrally formed upper side beam 1, an integrated side wall panel 2, an integrally formed lower side beam 3 and a lower side wall 4; The beam 1 is riveted with the integrated side wall panel 2 below; the side wall panel 2 is riveted with the integrally formed lower side beam 3 below; Inside the vehicle body; the lower side beam 3 is riveted with the lower side wall 4 below.

[0019] The lower part of the upper side beam 1 is provided with a wing edge 1a; the wing edge 1a is riveted with the side wall panel 2 . The upper side beam 1 is an integrally formed box beam of aluminum alloy material. The side wall panel 2 includes a side panel 2a, a side column 2b and a side column 2c with a triangular cross-section and wings. The side plates 2a are equidistant and alternately provided with side columns 2b with triangular cr...

Abstract

The invention discloses a side wall structure for a hopper car. The side wall structure comprises an integrally formed upper side beam (1), an integrated side wall plate (2), an integrally formed lower side beam (3) and a lower side wall (4). The upper side beam (1) and the integrated side wall plate (2) below are riveted. The side wall plate (2) and the integrally formed lower side beam (3) below are riveted. The side wall plate is in a wall plate and side column integrated plate-column structure, and the side columns are arranged on the inner side of the car body. The lower side beam (3) and the lower side wall (4) below are riveted. According to the side wall structure, by means of the integrated side wall plate with the built-in side columns, both the strength reduction due to rivet holes and the increased weight and cost due to the usage of rivets are prevented, the side columns are arranged inside, so that space among the side columns is used, and the car body volume is increased.

Description

technical field [0001] The invention relates to the technical field of hopper cars, in particular to a side wall structure of a hopper car. Background technique [0002] The side columns of the side wall structure of the existing railway coal hopper car are all set on the outside of the car body. As one of the main load-bearing components of the side wall, the side columns are all made of Large cross-section hollow rectangular tubular structure, and because the side pillars are all arranged on the outside of the car body, the space between the side pillars cannot be utilized. In addition, the connections between the side columns and the side wall panels are all made by riveting with rivets. On the one hand, the strength of the side wall panels is reduced due to the rivet holes due to the large number of rivets; In some cases, the weight and cost of the rivets are also increased. Contents of the invention [0003] The technical problem to be solved by the present inventio...
