Description

Technical Field

[0001] The utility model relates to the technical field related to railway tracks, in particular to an anti-deformation railway track shock absorber. Background Art

[0002] Railway tracks are referred to as rails, iron tracks, and tracks. They are mainly used on railways and work with switches to allow trains to run without turning. Railway tracks are usually composed of two parallel steel rails, which are fixed on sleepers. Under the sleepers is ballast, which is fastened by rail supports, fasteners, rail clamps, track splints, spring bars, railroad spikes and other railway accessories. When high-speed trains or trains are running on railway tracks, shock absorbers are installed under some tracks to suppress the shock caused by the rebound of springs after shock absorption and the impact from the road surface, in order to accelerate the attenuation of the vibration of the frame and the body, so as to improve the running smoothness of the train. When passing through uneven roads, although the shock-absorbing spring can filter the vibration of the road surface, the spring itself will still have reciprocating motion, and the shock absorber is used to suppress this spring jumping. The current railway track shock absorber has a short service life and often needs to be replaced and repaired. Therefore, a deformation-resistant railway track shock absorber is particularly needed.

[0003] However, most of the existing railway track shock absorbers will be deformed after a period of use due to long-term pressure from trains, which will affect the usability, reduce the life and use effect of the shock absorbers, and may also cause train turbulence and create safety hazards.
