Embodiment Construction

[0026] The present invention will be further described below in conjunction with accompanying drawing.

[0027] A grinding amount analysis method based on grinding wheel end grinding rail, such as figure 1 shown, including the following steps:

[0028] Step 1: Measure the rail profile before grinding.

[0029] Before grinding, select N measuring points at different positions along the longitudinal direction of the rail, and mark the positions of each measuring point. Use the rail profile measuring equipment to measure the profile of the rail before grinding. The profile discrete point data is denoted as RB i (i=1, 2, 3...N).

[0030] Step 2: Carry out rail grinding operations.

[0031] Set the working conditions of the grinding equipment (inclination angle of the grinding wheel, grinding pressure, rotating speed of the grinding wheel, travel speed, etc.), and use a single grinding wheel in the grinding equipment to grind the rail for M times. The situation is the same. T...

Abstract

The invention discloses a grinding amount analysis method based on a grinding wheel end face grinding steel rail. The grinding amount analysis method comprises the steps that firstly, measuring pointsare arranged in the longitudinal direction of the steel rail before grinding, and the profile of the steel rail at each measuring point is measured; the profile of the steel rail before polishing isreconstructed, and further the profile of the steel rail at each measurement point after reconstruction is obtained; and then the steel rail is ground for multiple times, and the grinding amount of the steel rail under the corresponding working condition can be conveniently and accurately calculated by measuring the profile of the steel rail before grinding and the grinding marks after grinding for each time and combining a certain data processing algorithm. Grinding amount parameters of the polishing equipment under different working conditions can be accurately mastered, effective guidance is formed for on-site polishing operation, and the polishing quality is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of rail grinding, and relates to a grinding amount analysis method for grinding rails based on a grinding wheel end face. Background technique [0002] As the scale of the railway network continues to expand, the demand for railway maintenance is also increasing rapidly. As an important track equipment of railways, steel rails will bear the comprehensive influence of train load, track state, line conditions and other factors, and will gradually deteriorate during service, resulting in diseases such as peeling off blocks, wavy wear, fat edges, and abnormal wear. If the rail disease cannot be dealt with in time and effectively, it will accelerate the development of the disease, seriously shorten the service life of the rail, and even endanger the traffic safety. Rail grinding provides an effective way to control the occurrence and development of its diseases. It can effectively prolong the service life of rai...
