Description

Technical field:

[0001] The invention relates to the technical field of railway transportation equipment, in particular to the technical field of railway container flat cars, and specifically to a multifunctional flat car end beam. Background technology:

[0002] The existing railway flat car end beams in my country have a simple structure and single function, and only play the role of bearing or installing container locks. At the same time, a multifunctional flat car end beam that integrates bearing, installing container locks, lifting and lifting has not yet been involved in the flat car field. Summary of the invention:

[0003] The invention provides a multifunctional flat car end beam, which can integrate bearing, installation of container lock seat, lifting and lifting of the car.

[0004] In order to achieve the above object, the present invention adopts the following technical scheme:

[0005] The present invention provides a multifunctional flat car end beam, which includes an upper cover plate, a lower cover plate, a first web plate, a second web plate, an end rotary lock seat plate, a sealing plate, a rotary lock bracket, a car-lifting pad plate, a lifting lug, and an emergency traction seat. The first web plate, the second web plate, and a sealing plate fixedly connected to the first web plate and the second web plate are fixedly arranged between the upper cover plate and the lower cover plate, an end rotary lock seat plate is arranged on the upper end of the upper cover plate close to the sealing plate, and a rotary lock is arranged on the end rotary lock seat plate; a lifting lug is fixedly arranged on the upper end of the lower cover plate close to the sealing plate, and a car-lifting pad plate is arranged on the lower end, and the car-lifting pad plate and the lifting lug are arranged on the outer side of the end beam; a rotary lock bracket is arranged on the outer side of the second web plate close to the sealing plate; and an emergency traction seat is arranged in the middle of the outer side of the first web plate.

[0006] The end beam adopts a variable-section box structure formed by welding double webs, with a small cross-section on the side facing the outside of the vehicle and a large cross-section on the side facing the middle of the vehicle.

[0007] The upper cover plate and the lower cover plate are formed into large arcs toward the middle of the vehicle.

[0008] A reinforcing rib is provided at the connection between the emergency traction seat and the first web.

[0009] The first web and the second web are provided with brake main pipe through holes.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. The present invention is multifunctional, and is provided with an end rotary lock seat plate, a vehicle-jacking pad plate, and a lifting lug, and can simultaneously have the functions of bearing, installing a container lock seat, lifting, and vehicle-jacking.

[0012] 2. The jacking pad and lifting lug of the flat car of the present invention are arranged on the outside of the end beam, which reduces the bending moment at the connection between the end beam and the middle beam when a heavy vehicle is lifted or jacked.

[0013] 3. The present invention adopts a variable-section box-type structure formed by welding double webs, with a small cross-section on the side facing the outside of the vehicle and a large cross-section on the side facing the middle of the vehicle. The upper and lower cover plates adopt a large arc transition toward the middle of the vehicle to ensure that their strength and rigidity meet the requirements.

[0014] 4. The present invention is provided with a sealing plate, which is used on a chassis with a full-length middle beam and no side beam structure. The chassis has a light weight and a large load capacity. The upper and lower cover plates of the end beam are large arcs toward the middle of the vehicle. The upper and lower cover plates are connected to the middle beam of the flat car chassis away from the sealing plate. The connection part is wider, which increases the rigidity of the chassis, effectively improves the stress concentration problem of the end beam, and improves the ability of the chassis to resist longitudinal impact.
