Funnel Ridge Support Structure for Hopper Carts

Abstract

The invention discloses a funnel ridge support structure for a hopper car. The funnel ridge support structure for the hopper car comprises an upper hopper ridge back, a first ridge plate, a side wall and an upper side beam, the lower end of the first ridge plate is mounted on one lateral surface of the upper funnel ridge back through a bent first ridge plate mounting plate, a second ridge plate is arranged on the other lateral surface of the upper funnel ridge back through a bent second ridge plate mounting plate, the upper end of the second ridge plate and the upper end of the first ridge plate are welded on the upper side beam in a butt welding mode, and one side of the first ridge plate and one side of the second ridge plate are welded on the inner lateral surface of the side wall in a butt welding mode; the other sides of the first ridge plate and second ridge plate are connected through a connecting plate; the lower end of the connecting plate is connected with the upper funnel ridge back through a rib plate. The funnel ridge support structure for the hopper car is suitable for the railroad hopper car.

Description

technical field [0001] The invention relates to the field of railway funnel cars, in particular to a funnel ridge support structure for funnel cars. Background technique [0002] At present, with the rapid development of railway hopper car technology in my country, heavy load and assembly efficiency have become the two development directions of railway hopper car, among which, the quality of the funnel ridge support structure directly affects the carrying capacity and assembly efficiency of railway hopper car . The existing funnel ridge support structure generally includes an upper funnel ridge, a ridge plate, a side wall and an upper side beam, the lower end of the ridge plate is butt-welded on the top of the upper funnel ridge, and the side of the ridge plate is butt-welded on the inner side of the side wall Above, the upper end of the ridge plate is butt-welded on the upper side beam, so that the ridge plate connects the upper side beam, the side wall and the back of the ...

AI Technical Summary

Problems solved by technology

[0003] 1. Since the ridge plate is a large-area sheet structure, the rigidity of the ridge plate is relatively poor. In this way, its ability to increase the load that the side wall can bear is limited; at the same time, it is very easy to deform during assembly and use , which increases the difficulty of assembly and reduces the assembly efficiency;

[0004] 2. Since the lower end of the ridge plate is in line contact with the top of the ridge of the upper funnel, it is difficult to ensure that the lower end of the ridge plate and the top of the ridge of the upper funnel are on the same straight line during welding, which further increases the difficulty of assembly. Reduced assembly efficiency
