Flexible anti-abrasion coupler joist device

Abstract

The invention discloses a flexible anti-abrasion coupler joist device, and relates to the technical field of locomotive connecting devices, in particular to a heavy haul train locomotive coupler joist device. The device comprises a bearing frame, a buffer suspender and a bearing structure, the two buffering hanging rods are connected with the two side portions of the bearing frame through hinged shafts correspondingly. A transverse joist of the bearing structure is of a strip-shaped plate structure, bolt holes are not machined in the two ends of the transverse joist, and the transverse joist is connected with the lower end of the buffering suspender through the bolt holes and bolts. The saddle-shaped bracket is of a frame structure and is arranged in the middle of the transverse bracket; the fixed locking plate is of a strip-shaped plate structure, is longitudinally inserted into the saddle-shaped bracket from the lower part of the transverse supporting beam, and is locked and positioned through a lock pin; the two bearing rollers are arranged on the two sides of the upper portion of the saddle-shaped bracket through pin shafts and used for bearing the car coupler. According to the device, the problems that in the prior art, an existing heavy-load locomotive is often unhooked, and meanwhile the maintenance and use cost is increased due to the fact that the coupler joist is greatly abraded are solved.

Description

technical field [0001] The invention relates to a flexible anti-wear coupler joist device, which relates to the technical field of locomotive and vehicle connection devices, and in particular to a coupler joist device for heavy-duty train locomotives. Background technique [0002] With the rapid development of heavy-duty transportation, the safety of heavy-duty train operation is a problem that heavy-duty transportation must face. [0003] The locomotive in the middle of the existing heavy-duty combined train adopts the No. 13 coupler with non-rigid coupling coupler, and the coupler joist boom is a rigid swing rod. After the nodding effect occurs on the rolling stock, the coupler is rigidly lifted, or the joist is driven forward when the hook is pulled, causing the boom to bend. , aggravated the lift of the coupler, and the problem of decoupling often occurred. The problem of coupler jumping is another challenge faced by existing heavy-duty trains [0004] The coupler betwe...

AI Technical Summary

Problems solved by technology

[0007] According to the above-mentioned prior art, the existing heavy-duty locomotive often has the problem of decoupling, and at the same time, the coupler joist wears a lot, which causes the technical problem of increased maintenance and use costs, and a flexible anti-wear coupler joist device is provided.

The invention mainly carries the coupler through the flexible coupler joist hanger rod, and adopts the rolling contact design, thereby solving the problem of large wear and tear of the train jump hook and the joist
