Hopper car body and railway transport car

Abstract

The invention relates to a hopper car body and a railway transport car. The hopper car body comprises a volume-fixing car body and a volume-expanding car body. The capacity expansion vehicle body comprises an inner-layer end wall and an outer-layer end wall matched with the inner-layer end wall, and the outer-layer end wall is arranged at the end of the capacity fixing vehicle body and connected with the capacity fixing vehicle body to define a containing cavity. The inner-layer end wall is arranged in the containing cavity and installed at the end of the solid volume vehicle body in a turnover mode. The inner-layer end wall is provided with an expansion position and an unloading position, and the inner-layer end wall can be overturned to the unloading position from the expansion position in the direction away from the outer-layer end wall and overturned to the expansion position from the unloading position in the direction close to the outer-layer end wall. Before goods are loaded, the inner-layer end wall is located at the expansion position close to the outer-layer end wall, and expansion of the hopper car body is achieved. And when the goods are unloaded, the inner-layer end wall is overturned to the unloading position in the direction away from the outer-layer end wall, and the goods are automatically unloaded under the action of gravity. Thus, the effective volume of the hopper car body can be enlarged, the cargo carrying capacity is improved, and meanwhile normal unloading of the hopper car body can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of railway transport vehicles, in particular to a funnel car body and a railway transport vehicle. Background technique [0002] Volume is one of the parameters used to evaluate the performance parameters of the rail transport car, which determines the loading capacity of the rail transport car. In the process of designing a railway transport vehicle, the maximum volume of the railway transport vehicle is often pursued when the boundary conditions are met. Specifically, by optimizing the structure of the railway transport vehicle, the space within the size range of the railway transport vehicle can be fully utilized as much as possible. [0003] As a type of railway transport vehicle, the funnel car body has a funnel and a bottom door structure. After the bottom door is opened, the goods in the car can be automatically unloaded under the action of gravity. However, in order to ensure the unloading function ...

AI Technical Summary

Problems solved by technology

However, in order to ensure the unloading function of the hopper car body, its end wall needs to have a certain inclination angle, and affected by the inclined end wall, the utilization rate of the space at the end of the hopper car body is low
