Description

Technical Field

[0001] The utility model belongs to the technical field of track maintenance equipment, in particular to a track maintenance device for subways. Background Art

[0002] The wheel rims of road vehicles are always in precise contact and friction with the rails during operation, and both the vehicle wheel rims and the rails are subject to wear. Especially when the train turns at a small radius, the wear will be more serious due to the centrifugal force, shortening the service life of the wheels and rails and increasing railway operating costs.

[0003] In order to solve the problems of wear and noise, most people still adopt the method of manually applying lubricating oil to the rails on a regular basis. This method is not only inefficient, but also requires long periods of bending over to damage the health of workers. It also wastes a lot of lubricating oil, takes up vehicle operating time, and is not safe enough. Utility Model Content
