Description

Technical Field

[0001] The utility model relates to the technical field of railway wheels, in particular to a railway wheel wear measurement structure. Background Art

[0002] Train wheels are important components in the train running system. Train wheels are in direct contact with the tracks and are closely related to the safe operation of the train. Therefore, after the train wheels have been used for a long time, it is necessary to test the wear of the train wheel tread to determine whether the train wheels can continue to be used.

[0003] Most of the existing methods for detecting the wear of train wheel treads are to use a tread wear detector to measure the wear of the train wheel treads at the bottom of the train. Since the tread wear detector is handheld, the handheld tread wear detector is unstable, resulting in deviations in the measurement data, which affects the judgment of the wear of the train wheel treads. When measuring the train wheel treads, the staff needs to squat to measure multiple locations of the train wheel treads. Squatting for a long time will cause fatigue to the staff, affecting the efficiency of the train wheel tread measurement.

[0004] The existing patent (publication number: CN219319249U) discloses a railway wheel wear measurement structure, which is achieved by moving the bottom plate to a stable ground, and then placing the railway wheel body to be measured on the top of the placing plate, and then inserting the rotating column into the socket, turning the dial block to move the second measuring rod, so that the baffle contacts the surface of the tread of the railway wheel body to be measured. At this time, the measured data can be judged by observing the scale groove, and the wear of the tread of the railway wheel body can be judged by comparing the measured data with the original data of the railway wheel body. By rotating the first measuring rod, different parts of the tread of the railway wheel body can be measured, so there is no need for personnel to squat down to measure the tread of the railway wheel body at multiple locations using a tread wear detector, which makes the staff tired and affects the efficiency of the tread measurement of the railway wheel body. It can also avoid the problem that the handheld tread wear detector is unstable, resulting in deviations in the measurement data, and affecting the judgment of the wear of the tread of the railway wheel body.

[0005] In view of the above problems, the existing patents provide solutions, but they are not easy to move and require the train wheels to be disassembled for inspection, resulting in a cumbersome and complicated train wheel inspection process. This not only consumes a lot of time and manpower costs, but also makes the train unable to operate normally during the inspection, affecting the train's use arrangements and operational efficiency, and reducing the practicality of the device.

[0006] Therefore, a railway wheel wear measurement structure is proposed. Utility Model Content
