Connecting structure of end wall, side wall and hopper ridge for hopper car

Abstract

Disclosed is a connecting structure of an end wall, a side wall and a hopper ridge for a hopper car. The connecting structure comprises partition boards; the lower ends of the partition boards are connected with the floor, the side edges of the partition boards are connected with the end wall, and the upper ends of the partition boards are connected with an upper end beam; the upper end beam is spliced with an upper side beam to form a frame structure, and the upper side beam is wrapped by the side wall; upper connecting plates are arranged between the side wall and the partition boards and are connected with the upper side beam and the upper end beam; a lower connecting plate is arranged between the lower ends of the two partition boards; the two side faces of the lower connecting plate are connected with the two partition boards respectively, and the bottom face of the lower connecting plate is connected with the floor; the lower end of a first ridge plate is arranged on one side face of an upper hopper ridge back through a first ridge plate mounting plate, and a second ridge plate is arranged on the other side face of the upper hopper ridge back through a second ridge plate; the upper end of the second ridge plate and the upper end of the first ridge plate are connected to the upper side beam, and one side edge of the first ridge plate and one side edge of the second ridge plate are connected to the side wall; the other side edge of the first ridge plate and the other side edge of the second ridge plate are connected through the connecting plates; and the lower ends of the connecting plates are connected with the upper hopper ridge back through connecting rib plates. The connecting structure 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 connection structure for an end wall, a side wall and a funnel ridge of a funnel car. Background technique [0002] At present, with the rapid development of railway hopper car technology in my country, heavy load has become a development direction of railway hopper car, among which, the quality of the connection structure between end wall, side wall and funnel ridge directly affects the carrying capacity of railway hopper car . The existing connection structure of end wall, side wall and funnel ridge generally includes end wall, floor, partition, upper end beam, upper side beam, side wall, ridge plate and upper funnel ridge, and the lower ends of the two partitions are connected to the floor respectively. The sides of the two partitions are respectively connected to the side walls of the end wall, the upper ends of the two partitions are respectively connected to the upper e...

AI Technical Summary

Problems solved by technology

[0003] 1. Since there is no connection between the two partitions, the support provided by the partition is limited, which is not conducive to improving the carrying capacity of the railway hopper car;

[0004] 2. Since the upper side beam is not directly connected to the upper end beam, but is indirectly connected to the upper end beam through the side wall, the upper side beam cannot form a frame structure with the upper end beam, thereby reducing the connection strength, thereby reducing the railway funnel car. Carrying capacity;

[0005] 3. Since there is no connecting structure between the partition and the side wall, the load that the side wall can bear is small, thereby reducing the load-carrying capacity of the railway hopper car;

[0006] 4. 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;

[0007] 5. 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
