Abstract

The invention relates to the technical field of railway track maintenance, in particular to a track profiling grinding method. A track profiling grinder is arranged at the initial position, the track transverse section where the rotary axis of a grinding head of the grinder is located serves as a datum plane, a rectangular coordinate system is built, coordinate parameters of track profiles and the initial position parameters of the grinder are obtained by measurement, a track profile to be grinded is determined, the straight line, crossed with the datum plane, of the track profile to be grinded serves as a grinding tangent line, the grinding head of the grinder is moved until the rotary axis of the grinding head is perpendicular to the grinding tangent line, the grinding head of the grinder is driven to move in the radial direction of the rotary axis of the grinding head until the lower end face of the grinding head coincides with the grinding tangent line, and the grinding head of the grinder is driven to move along the track profile to be grinded to finish grinding of the track profile to be grinded. According to the track profiling grinding method, the grinding head of the grinder is moved according to the coordinate parameters until the rotary axis of the grinding head is perpendicular to the grinding tangent line, and the effect of adopting the end face of the grinding head for grinding when grinding of any angle is performed is achieved.

Description

technical field

[0001] The invention relates to the technical field of railway track maintenance, in particular to a method for grinding a track profile. Background technique

[0002] With the development of high-speed and heavy-duty railways, rails will have defects such as fatigue cracks, fat edges and wave wear, which will affect the stability and safety of railway vehicles. At the same time, the above defects will accelerate rail failure and bring greater economic loss. Preventive and remedial maintenance of rails is a necessary measure to prolong rail life, improve comfort, economy and safety. At present, rail repair methods mainly include grinding, planing, milling, and manual grinding. Among them, the use of efficient grinding machines to repair rails is the most common.

[0003] At present, the commonly used grinding methods in China mainly include various small grinding machines for manual control grinding. The grinding head is driven by a gasoline internal combus...
