[0002] When the train is running, the wheel, rail and rail head will contact and wear will occur. The wear is usually concentrated on the tread of the rail head and the arc segment and the straight segment of the side. The existing rail wear measurement methods include contact measurement and non-contact measurement. Once the rail wear (wear) exceeds the limit, it will bring major hidden dangers to railway transportation safety. Therefore, it is very important to measure rail wear.

[0003] In the prior art, since the measurement of rail wear is performed using a specific measuring device, the existing rail wear measurement device is composed of a ruler frame, a clamp block, a side grinding ruler, a vertical grinding ruler and a limit block, and then the ruler frame and the clamp block are fixed on the rail by the limit block, and then the side grinding ruler and the vertical grinding ruler are connected to the two sides of the rail at the same time, and then the rail wear is measured by observing the scale. However, during measurement, the staff is required to manually adjust the position of the rail where the ruler frame is located, so the connection between the clamp block pair and the rail cannot be controlled, resulting in excessive clamping and damage between the clamp block and the rail.
