[0030] During operation, the motor A201 is started to rotate the threaded rod A202, so that the moving plate 203 drives the detection roller 207 to move forward and backward.

[0031] Further, a telescopic rod 204 is fixedly arranged on the inner wall of the movable plate 203, and the telescopic rod 204 is composed of a sleeve rod and a slide rod. A device block 205 is fixedly arranged on the bottom surface of the output rod of the telescopic rod 204, and a rotating rod 206 is arranged inside the device block 205. The surface of the rotating rod 206 and the inner wall of the device block 205 are rotatably connected by a bearing;

[0032] During operation, when there is an uneven road, the detection roller 207 is always in contact with the road surface due to the characteristics of the telescopic rod 204 and the spring 208.

[0033] Furthermore, a detection roller 207 is fixedly sleeved on the surface of the rotating rod 206, a spring 208 is fixedly arranged on the top surface of the device block 205 and the inner wall of the telescopic rod 204, and the spring 208 is always in a loose state.

[0039] Working principle: When in use, the four universal wheels 305 are used to move to the top of the roadbed where the flatness detection is required. According to the slope corresponding to the roadbed, the motor B301 on the corresponding side is started to rotate the threaded rod B302, so that the moving block 303 drives the universal wheel 305 to move up and down until the scale observation disk set inside the base 1 is level, and the universal wheel 305 can continue to be started to move. At this time, the detection roller 207 moves in contact with the road surface. When an uneven road appears, the detection roller 207 is always in contact with the road surface through the characteristics of the telescopic rod 204 and the spring 208. The position of the connecting block 209 inside the scale plate 210 is used to quickly read the flatness difference and the actual data. When it is necessary to perform corresponding detection on road surfaces of different widths, the motor A201 is started to rotate the threaded rod A202, so that the moving plate 203 drives the detection roller 207 to move forward and backward.
