[0037] The working principle of the present invention is:

[0038] When the mobile module is working: the external power device drives the mobile wheel 701 to move through the rotating shaft 2 702, and the mobile wheel 701 drives the detection frame 101 to move through the mobile module, thereby driving the overall movement. When steering is required, the output shaft of the servo motor 4 705 drives the mobile wheel 701 and the rotating shaft 2 702 to rotate through the bogie 703, thereby realizing the overall steering.

[0039] When the first position adjustment unit is working: the output shaft of the servo motor 301 drives the position adjustment frame 304 to slide in the track groove 305 through the screw 303, and the position adjustment frame 304 drives the spacing adjustment unit to move when sliding. When moving, the connecting block 2 315 slides in the connecting groove plate 407, and the spacing adjustment unit drives the three-dimensional radar detection unit to move, thereby adjusting the height of the three-dimensional radar detection unit.

[0040] When the spacing adjustment unit is working: the piston rod of the electric cylinder 314 drives the support seat 307 at one end of the position adjustment frame 304 to move through the connecting block 313, and the support seat 307 at one end of the position adjustment frame 304 drives the adjacent support seat 307 to move through a diamond mechanism composed of half of the side of the connecting rod 1 308, half of the side of the connecting rod 2 309, the connecting rod 310 and the connecting rod 4 311, and then the support seat 307 is connected to another adjacent connecting rod 308 through the other half of the side of the connecting rod 1 308 and the other half of the side of the connecting rod 2 309. Half of the side of one 308 and half of the side of another adjacent connecting rod 2 309 form another diamond mechanism to drive the adjacent support seats 1 307 to move, so that except for the middle support seat 1 307, the remaining support seats 1 307 all move, and then evenly adjust the distance between two adjacent support seats 1 307, and then adjust the distance between two adjacent three-dimensional radar detection units, so as to facilitate the detection of different roads, thereby improving the scope of application, and the adjustment of the distance is stable, convenient and fast, which greatly improves the efficiency of detection.

[0041] When the three-dimensional radar detection unit is working: the mobile module drives the overall movement through the detection frame 101, so that multiple three-dimensional radar detectors 202 move. During the movement of the three-dimensional radar detector 202, the compaction and density data of the highway road surface are detected, and the detection results are fed back to the program control system in the control box 601. When an unqualified area appears, it is marked by the marking unit, thereby avoiding the step of sampling the highway core in traditional highway road surface detection, which not only improves the detection efficiency, but also improves the detection effect. The detection range is also greatly improved, while reducing the workload of the detection personnel and saving the detection cost. At the same time, multiple continuous multi-road surface detections can be carried out.

[0042] When the pressure adjustment unit and the flatness detection unit are working: initially, a flat test plate is taken and placed under the flatness detection unit for initial calibration, the piston rod of the electric cylinder 401 drives the position adjustment frame 404 to descend in the track groove 403, and the position adjustment frame 404 drives the plurality of flatness detection units to descend through the guide shaft 406, so that the pressure detection roller 413 contacts the test plate, and when it continues to descend, the pressure detection roller 413 drives the pressure detection rod 411 to move through the pressure detection frame 412, and the pressure detection rod 411 drives the spring 416 to be compressed through the support plate 415, and the spring 416 is compressed. 16 applies pressure to the pressure sensor 417, and the pressure sensor 417 feeds back a pressure value. Initially, a pressure value is set (set according to actual use). When the road surface is tested for flatness, the mobile module drives the overall movement through the detection frame 101. When the pressure detection roller 413 moves, if it encounters an uneven road surface, the pressure value of the pressure sensor 417 will change. When the pressure value change range of the pressure sensor 417 exceeds the qualified range (the qualified range is set according to the actual detection), it means that the road surface is unqualified. At this time, the road surface here is marked by the marking unit.

[0043] When the spacing adjustment unit adjusts the spacing between multiple support seats 1 307, the connecting block 2 315 drives the remaining connecting blocks 3 408 except the middle connecting block 3 408 to move through the connecting slot plate 407, and the connecting block 3 408 drives the flatness detection unit to move through the support seat 2 409, thereby adjusting the spacing between the multiple flatness detection units to adapt to the detection of different road surfaces.

[0044] When the second position adjustment unit and the marking unit are working: the output shaft of the servo motor 2 501 drives the lead screw 2 505 to rotate, the lead screw 2 505 drives the position adjustment frame 3 504 to slide in the track groove 3 503, the position adjustment frame 3 504 drives the linear motor 507 to move through the mounting plate 506, the linear motor 507 drives the marking unit to move through the slider 508, thereby adjusting the height of the marking unit; the slider 508 is driven horizontally by the linear motor 507 to adjust the horizontal position of the marking unit, so that the marking unit moves to the position to be marked. When marking, the output shaft of the servo motor 3 511 drives the spraying device 509 to rotate through the connecting frame 510, and the nozzle of the spraying device 509 sprays paint for marking, so as to facilitate the subsequent repair of the unqualified road surface.

[0045] It should be noted that the start and stop of the power parts, the recording of detection data and the overall working process of the present invention are all controlled by a program control system and an external wireless controller.
