[0002] In the railway transportation system, as the infrastructure for supporting and guiding the train to run, the quality and integrity of the rail are directly related to the running safety of the train and the life and property safety of passengers. During the use of the rail, due to environmental factors, vehicle loads, material aging and other reasons, various damages will occur. Among them, the weld area is more prone to serious problems such as cracks and fractures. Therefore, regularly inspecting the rail welds, promptly discovering and dealing with potential defects, is an important measure to ensure the safety of railway operation.

[0027] In an embodiment of the present utility model, the moving component 2 includes a vehicle frame 21, the vehicle frame 21 is arranged on the top of the track body 1, a deceleration asynchronous motor 22 is fixedly installed on the top of the vehicle frame 21, a driving sprocket 23 is fixedly installed on the outer side of the output shaft of the deceleration asynchronous motor 22, a rotating shaft 24 is rotatably installed inside the vehicle frame 21, a driven sprocket 25 is fixedly installed on the outer side of the rotating shaft 24, a transmission chain 26 is installed between the driving sprocket 23 and the driven sprocket 25 in a transmission manner. When the deceleration asynchronous motor 22 on the vehicle frame 21 is started, the driving sprocket 23 rotates, and with the cooperation of the transmission of the driven sprocket 25 and the transmission chain 26, the rotating shaft 24 rotates. Wheels 27 are fixedly installed on the outer side of the rotating shaft 24. Two sets of rotating shafts 24 are provided, and two sets of wheels 27 are provided on the outer side of a single set of rotating shafts 24.

In addition, three sets of monitors 211 are provided, and the three sets of monitors 211 are annularly arrayed outside the track body 1, so that the detection effect is better.

Thus, the top seat 39 can move up and down in cooperation with the top shaft 38. A distance measuring instrument 310 is clamped on the top of the top seat 39, so that the distance measuring instrument 310 can move up and down, and thus the ground clearance height of the distance measuring instrument 310 can be flexibly adjusted. When the car body stops at the target position, it is convenient to set the fixed measurement distance, and then the fixed measurement can be better carried out.

[0029] Working principle: When the deceleration asynchronous motor 22 on the vehicle frame 21 is started, the driving sprocket 23 rotates, and through the transmission of the driven sprocket 25 and the transmission chain 26, the rotating shaft 24 rotates, so that the wheels 27 rotate, and the car body moves outside the track body 1.

Further, when the hydraulic cylinder 37 is started, the multiple groups of support plates 33 move synchronously in cooperation with the hinge shaft 34, so that the top seat 39 can move up and down in cooperation with the top shaft 38, so that the distance measuring instrument 310 can move up and down, and thus the ground clearance height of the distance measuring instrument 310 can be flexibly adjusted. When the car body stops at the target position, it is convenient to set the fixed measurement distance, and then the fixed measurement can be better carried out.

[0030] The above has generally described the present utility model in detail. However, based on the present utility model, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, modifications or improvements that do not depart from the spirit and idea of the present utility model are within the protection scope of the present utility model.
