Abstract

The invention discloses a subway steel rail grinding wagon which comprises a wagon body and a steel rail grinding trolley hung on the lower portion of the wagon body through a lifting mechanism, and the steel rail grinding trolley comprises two grinding trolleys hinged to each other. The steel rail grinding trolley further comprises an elastic traction rod and a rigid traction rod, one grinding trolley is connected with the trolley body through the elastic traction rod, and the other grinding trolley is connected with the trolley body through the rigid traction rod. Traction of the steel railgrinding trolley is achieved through the elastic traction rod and the rigid traction rod. The technical problems that an existing subway steel rail grinding wagon is limited in application occasion, poor in operation stability and poor in grinding quality and effect can be solved.

Description

technical field [0001] The invention relates to the technical field of track engineering machinery, in particular to a subway rail grinding vehicle used in railway engineering maintenance. Background technique [0002] The rail grinding vehicle is a rail engineering vehicle mainly used for grinding the main line of the track. There are special grinding vehicles for the turnout operation, and there are also individual grinding vehicles that can be used for both main line grinding and turnout grinding. However, the existing rail grinding vehicles generally have many technical problems such as low operating efficiency, hidden safety hazards, heavy environmental pollution, poor dust collection effect, and deviation of the operating landing point, which leads to unsatisfactory overall grinding performance. At present, there are mainly the following types of rail grinding vehicles widely used in China: [0003] 1) PGM-48 grinding car. This type of grinding car is composed of thr...
