Description

Technical Field

[0001] The present invention relates to the technical field of wheel detection, and more specifically, it relates to a wheel tread wear detection device and method. Background Art

[0002] Train wheels are important components in the train running system. Train wheels are in direct contact with the track and are closely related to the safe running of the train. Therefore, after the train wheels are used for a long time, it is necessary to detect the wear degree of the train wheel tread to determine whether the train wheels can continue to be used. Most of the existing methods for detecting the wear degree of the train wheel tread are to use a tread wear detector at the bottom of the train to measure the wear degree of the train wheel tread. Since the tread wear detector is handheld, there will be a situation where the handheld tread wear detector is unstable, resulting in deviation of the measurement data, which affects the judgment of the wear condition of the train wheel tread. When measuring the train wheel tread, it is necessary for the staff to squat down to measure multiple places on the train wheel tread. Squatting for a long time will cause fatigue to the staff and affect the efficiency of measuring the train wheel tread. Summary of the Invention
