Transport vehicle and vehicle body thereof

Abstract

The invention discloses a transport vehicle and a vehicle body thereof. The vehicle body comprises a bottom frame, side walls and end walls. The side walls are arranged on the two sides of the bottom frame. The end walls are arranged at the front end and the rear end of the bottom frame. A cavity for containing material is defined by the side walls and the end walls. A wall body of each side wall and a wall body of each end wall respectively comprise at least one aluminum profile wall body unit of a hollow structure. Each wall body unit comprises an outer wall board and an inner wall board, wherein a hollow structure is defined by the outer wall board and the inner wall board. Compared with the prior art, the vehicle body has the advantages that side columns arranged on the side walls and the end walls are omitted, the equal-strength design concept is adopted, the aluminum profile wall body units of the hollow structure are adopted, and the side walls and the end walls have smaller widths under the condition that the same structural strength is obtained; in this way, on one hand, the capacity of the vehicle body can be improved, and on the other hand, the design of the vehicle body can be easily optimized for the vehicles with the same use limit.

Description

technical field [0001] The invention relates to the technical field of railway engineering vehicles, in particular to a transport vehicle and its body. Background technique [0002] Coal hopper car is a typical transportation vehicle. Coal hopper car has the advantages of high unloading efficiency, low comprehensive investment, low daily operation cost, and good working conditions. It is the most economical transportation method for bulk bulk goods such as coal. The consensus of foreign and foreign railway transportation companies, especially the lines that are close to the mining area, have a large transportation volume, and have fixed coal transportation sections, have more obvious transportation economic effects. [0003] The body of a typical coal hopper car in the prior art mainly includes an underframe 2', two side walls 1' and two end walls 6', and the two side walls 1' are respectively connected to both sides of the underframe 2' , the two end walls 6' are respectiv...

AI Technical Summary

Problems solved by technology

[0004] When the side column 3' is located outside the side wall panel, the side wall panel is far away from the vehicle limit, which cannot make full use of the vehicle limit, and the vehicle volume is small

In addition, the end wall 6' and the side wall 1' have a large number of components, complex structures, and difficult manufacturing

[0005] When the side column 3' is located inside the side wall panel, the inner wall of the vehicle body is not smooth, and there are many corners inside the vehicle body. Coal accumulation is likely to occur at the side column 3' and corners. In winter, coal is likely to freeze and affect unloading, so the cargo unloading The net rate is much lower than that of the car body with smooth inner wall
