Connecting structure for side walls, funnel ridges and middle beam of hopper car

Abstract

The invention relates to a connecting structure for side walls, funnel ridges and a middle beam of a hopper car. The connecting structure comprises an upper funnel ridge and a lower funnel ridge, wherein the two ends of the upper funnel ridge and the lower funnel ridge are respectively welded on the two side walls; an opening is formed in the back of the upper funnel ridge; the middle beam is inserted into the opening; a sealing plate is arranged at the opening part of the opening; lateral sealing plates are arranged between the two side walls of the middle beam and the opening; the height of the top end on the back of the lower funnel ridge is higher than the height of the bottom of the middle beam; a U-shaped opening is formed in the position corresponding to the middle beam at the top end on the back of the lower funnel ridge; the bottom of the middle beam is arranged in the U-shaped opening; the lower end of a first ridge plate is mounted on a side wall on the back of the upper funnel ridge through a first ridge plate mounting-plate; a second ridge plate is mounted on the other side wall of the upper funnel ridge through a second ridge plate mounting-plate; the upper ends of the second ridge plate and the first ridge plate are both butt-joined with an upper lateral beam; one lateral edge of the first ridge plate and the second ridge plate are both butt-jointed with the side walls; the other lateral edges of the first ridge plate and the second ridge plate are connected through a connecting plate; the lower end of the connecting plate is connected with the upper funnel ridge through a rib plate. The connecting structure is fit for a railway hopper car.

Description

technical field [0001] The invention relates to the field of railway funnel cars, in particular to a connection structure for a side wall, a funnel ridge and a middle beam of a funnel car. Background technique [0002] At present, with the rapid development of railway hopper car technology in my country, heavy load and assembly efficiency have become important development directions of railway hopper cars. It affects the carrying capacity and assembly efficiency of railway hopper cars. The existing connection structure for the side wall of the funnel car, the funnel ridge and the middle beam generally includes the upper funnel ridge, the middle sill, the lower hopper ridge, the ridge plate, the side wall and the upper side beam, the upper hopper ridge and the lower hopper ridge. The two ends are respectively welded on the inner sides of the walls on both sides. There is an opening on the back of the upper funnel for passing through the middle beam. The middle beam is inserte...

AI Technical Summary

Problems solved by technology

[0003] 1. Since the two sides of the middle beam are directly welded to the opening of the back of the upper funnel, the dimensional accuracy of the opening on the back of the upper funnel is required to be high, and the assembly accuracy is also high, so the process is more difficult, thereby reducing assembly. efficiency;

[0004] 2. Since the height of the top of the back of the lower funnel is much lower than that of the bottom of the middle beam, there is no connection between the back of the lower funnel and the middle beam, which greatly reduces the strength of the whole vehicle, thereby reducing the weight of the railway funnel car. Carrying capacity;

[0005] 3. Since the ridge plate is a large-area sheet structure, the stiffness 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;

[0006] 4. Since the lower end of the spine plate is in line contact with the top of the upper funnel spine, it is difficult to ensure that the lower end of the spine plate and the top of the upper funnel spine are on the same straight line during welding, which further increases the difficulty of assembly. Reduced assembly efficiency
