Problems solved by technology

After the opening and operation of rail transit, the rails have been in a harsh environment for a long time. Due to the dynamic effect of the train, the natural environment, and the quality of the rail itself, the rails often suffer from damage, such as fat edges, rail bows, scratches, and peeling off. Phenomena such as lumps, weld bumps, rail top surface bumps, saddle-shaped wear, wavy wear, fish scale cracks and other phenomena have resulted in reduced rail life, increased maintenance workload, increased maintenance costs, and even seriously affected driving safety.

Abstract

The invention provides a steel rail maintenance method and device, and relates to the field of steel rail maintenance. The steel rail maintenance method comprises the steps of firstly, measuring an actual profile of a steel rail through a profile measuring instrument, and then comparing the actual profile with a target profile of the steel rail to determine a grinding strategy for the steel rail,wherein the grinding strategy at least comprises the grinding position and the grinding amount; finally, grinding the steel rail according to the determined grinding strategy. According to the methodand device, since the profile measuring instrument is utilized for collection, and the target profile is utilized as a reference, grinding of the steel rail is more precise.

Description

technical field [0001] The invention relates to the field of rail maintenance, in particular to a rail maintenance method and device. Background technique [0002] Rail refers to the route paved with strip steel for trains, trams, etc. At present, with the improvement of use demand, the amount of rail laying is also increasing year by year. After the opening and operation of rail transit, the rails have been in a harsh environment for a long time. Due to the dynamic effect of the train, the natural environment, and the quality of the rail itself, the rails often suffer from damage, such as fat edges, rail bows, scratches, and peeling off. Phenomena such as lumps, weld bumps, rail top surface bumps, saddle wear, wave wear, fish scale cracks and other phenomena have resulted in reduced rail life, increased maintenance workload, increased maintenance costs, and even seriously affected driving safety. [0003] Therefore, it is necessary to maintain the rail damage in time to o...
