AI Technical Summary

Technical Problem

In the prior art, the rail crawling problem caused by longitudinal movement of railway rails leads to serious damage to the railway line, and the existing anti-climbing device is prone to loosening and failure, which cannot effectively solve the problem of sharp rail crawling, and the pressure of strengthening fastener buckle affects the service life.

Method used

The railway rail-type anti-climbing device is adopted, consisting of a fixed part and an anti-climbing part, which is connected to the rail through bolting. The boss, iron seat and iron pad are used to restrict the longitudinal movement of the rail. The force is transmitted to the sleepers, roadbeds, and roadbeds through the fastener system to achieve the constraint of longitudinal movement.

Benefits of technology

Effectively prevent rail crawling, improve line stability and integrity, reduce diseases, adapt to different fastener systems and rail models, facilitate installation and reduce maintenance costs.

Abstract

The railway connecting rail type anti-climbing device is composed of a fixing part and an anti-climbing part, and one side of the fixing part is attached to a steel rail; a bolt mounting through hole is coaxially formed in the anti-rotation groove, and the bolt mounting through hole is used for mounting a connecting bolt; assembling through holes corresponding to the bolt mounting through holes are formed in the steel rails; the connecting bolt extends out of the assembling through hole and then is sequentially provided with a gasket, a nut and a nut locking cap; the nut locking cap is provided with a cotter pin; the anti-climbing part is provided with an integrally-formed boss and further comprises a fastener system. The boss is matched with the iron seat and the iron base plate; when a creeping phenomenon occurs, the iron base and the iron base plate can restrain the device; force generated by steel rail crawling is transmitted to the fastener system through the device and then is sequentially transmitted to a sleeper, a ballast bed and a roadbed through the fastener system, steel rail crawling is prevented, and restraining of longitudinal movement of the steel rail is achieved. The problem of steel rail crawling is solved, and diseases of a sensitive area of a railway line are reduced; the structure is stable, installation is convenient, assembly is simple, implementation is easy, adaptability is wide, and safety and reliability are achieved.
