[0024] During the road construction process of the municipal engineering project, it is necessary to detect the length, flatness and inclination of the construction section, and the corresponding road measuring device can be used for the operation; when the above-mentioned municipal road measuring device is in use, the movement trajectory of the measuring device will be offset, resulting in the phenomenon that the data of the measurement result is not accurate, especially for the measurement of road length. Once the measuring device is offset, the measurement data will have a large error. The present application uses the auxiliary measuring device to place the mobile frame 1 and the measuring mechanism 2 in a suitable position, and start the telescopic mechanism 4 on the lifting plate 404. 05. The telescopic rod 406 pushes the positioning plate 407 to move outward, so that the body of the positioning plate 407 exceeds the operating range of the road surface. Subsequently, the lifting mechanism 402 on the fixed plate 401 is opened, and the lifting rod 403 drives the lifting plate 404 to descend to a suitable position, so that the rotating roller 409 on the positioning plate 407 descends below the guide surface.

When the measuring mechanism 2 moves, the small motor 415 is started, and the rotating shaft 413 drives the cleaning brush 414 to rotate, so that the gravel particles on the vertical side of the road are swept away.

[0027] Working principle: During the road construction process of municipal engineering projects, it is necessary to detect the length, flatness, inclination, etc. of the construction section, and the corresponding road measuring device can be used for the operation; when the above-mentioned municipal road measuring device is in use, the movement trajectory of the measuring device will be offset, resulting in the phenomenon that the data of the measurement result is not accurate, especially for the measurement of road length. Once the measuring device is offset, the measurement data will have a large error. The present application uses an auxiliary measuring device to place the mobile frame 1 and the measuring mechanism 2 in appropriate positions, start the telescopic mechanism 405 on the lifting plate 404, and the telescopic rod 406 pushes the positioning plate 407 to move outward, so that the plate body of the positioning plate 407 exceeds the operating range of the road surface, and then starts the lifting mechanism on the fixed plate 401. 402, the lifting rod 403 drives the lifting plate 404 to descend to a suitable position, so that the rotating roller 409 on the positioning plate 407 descends below the guiding surface, and then the telescopic mechanism 405 is started again to make the positioning plate 407 move toward the lifting plate 404. After the rotating roller 409 contacts the vertical surface of the road, the operation of the telescopic mechanism 405 is stopped, thereby avoiding the movement trajectory of the measuring device from being offset and reducing the measurement error.
