Abstract

The invention relates to a railway steel rail head flaw detection vehicle and a usage method thereof. The device comprises an arc-shaped frame, a cross beam, a probe position adjusting assembly and aside wheel assembly, one side wall of the arc-shaped frame is fixedly connected with one end of the cross beam, first horizontal wheels are installed at the two ends of the bottom of the arc-shaped frame respectively, the probe position adjusting assembly is installed in the middle of the arc-shaped frame, the side wheel assemblies are fixed to the two ends of the bottom of the inner side wall ofthe arc-shaped frame respectively, and each side wheel assembly comprises a magnet base and a first side wheel frame. In the detection walking process, the first side wheel is tightly attached to theinner side face of the steel rail all the time and does not shake, it is guaranteed that the detection portion of each probe does not deviate, the detection accuracy is improved, the multiple probes are integrated, the vulnerable surface of the steel rail can be covered, and therefore the detection efficiency is greatly improved.

Description

technical field

[0001] The invention relates to the technical field of rail detection, in particular to a railway rail head flaw detection vehicle and a method for using the same. Background technique

[0002] Rail defects used in high-speed rail or subway directly affect the operation safety of high-speed rail. During the operation of high-speed rail or subway, the rails will be rubbed and squeezed, causing cracks in the rails. In addition, there will be some trace defects inside the rails when they leave the factory. Under the repeated action of high-speed rail for a long time, it is easy to produce defects such as cracks, slag falling, and fractures, and the internal defects of the rail will gradually increase. Under the action of fatigue stress, it is very easy to break and seriously affect driving safety. Therefore, it is necessary to regularly inspect the rails. , the cracks and shrinkage defects on the surface of the rail head are detected by the eddy current generate...
