[0002] Railway track detector is a professional equipment for evaluating and connecting railway track geometry state and structural integrity, which plays a vital role in ensuring the safe operation of railway.

[0003] When using the railway track detector, the guide wheels and the walking wheels at the bottom of the detector need to be set at the top of the railway track. The operator pushes the railway track detector at the top of the railway track by hand. During the driving process, the detection equipment at the top of the detector detects the geometry and structure of the railway track. Since the operator needs to drive the detector at least five kilometers on the top of the railway track during each detection, the walking wheels and the guide wheels will be rotated and rubbed on the top of the railway track. The walking wheels will be worn and damaged by the railway track. Since the detector is provided with multiple guide wheels on one side and only a single walking wheel on the other side, the load borne by the walking wheel will be greater than that borne by the guide wheels. After a long time of driving, the walking wheel will be deformed due to the wear of the railway track. When replacing the walking wheel, the walking wheel and the detector need to be removed as a whole, which is time-consuming and laborious. Therefore, a railway track fault automatic detector is designed. SUMMARY
