Lower hopper ridge of hopper car

Abstract

The invention discloses a lower hopper ridge of a hopper car. The lower hopper ridge of the hopper car is made of aluminum alloy materials, and adopts an integrally molded structure. The lower hopper ridge comprises a lower transverse ridge, a connecting part, a supporting part and stiffening beams, wherein the lower transverse ridge comprises two side plates, and one ends of the side plates are fixedly connected in an acute angle; the connecting part comprises two connecting plates, and one ends of the connecting plates are respectively and fixedly connected with the other ends of the two side plates; an included angle between the two connecting plates is larger than that between the two side plates; the supporting part comprises two supporting plates arranged oppositely, and the two supporting plates are respectively and fixedly connected with the other ends of the two connecting plates. Through the adoption of the lower hopper ridge of the hopper car, the dead weight of the lower hopper ridge can be greatly lowered under the situation that the operating requirements of the lower hopper car are met, the improvement of the loading of the car is facilitated, and the lower hopper ridge solves the technical problem that because a lower hopper ridge in the prior art adopts a steel welded structure, the dead weight of the lower hopper ridge is large, and the lower hopper ridge is adverse to the improvement of the loading of the car.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a lower funnel ridge of a funnel car. Background technique [0002] The funnel car is usually a kind of truck with the end wall inclined inward, the side is a large arc or plate-column structure, and the lower part of the car body is equipped with a funnel car. The goods are loaded from the top, and the bottom door of the funnel is opened by wind or mechanical touch when unloading, and the goods are automatically unloaded by their own gravity. [0003] At present, the lower funnel ridge of the hopper car basically adopts an inverted V-shaped structure, which ensures the vertical relationship between the lower transverse ridge and the bottom door panel at the mating position. Moreover, the existing lower funnel ridge is usually a steel welded structure with a relatively large dead weight, which is unfavorable for increasing the load capacity of the vehicle when the axle load is ...

AI Technical Summary

Problems solved by technology

[0004] The application provides a lower funnel ridge of a funnel car, which improves the technical problem in the prior art that the lower funnel ridge is a steel assembly and welded structure, which causes the lower funnel ridge to have a large self-weight, which is not conducive to increasing the vehicle load
