The telescopic shell 208 and the main rod 203 are fixedly connected. Sliding connection, the first threaded rod 206 is fixedly connected to the first gear 209, the first gear 209 engages with the second gear 210, the second gear 210 is fixedly connected to the second threaded rod 211, the second threaded rod 211 and the telescopic shell 208 are rotatably connected, the second threaded rod 211 is threadedly connected to the first movable plate 212, the first movable plate 212 is fixedly connected to the movable rod 213, the movable rod 213 passes through the telescopic shell 208 and is slidably connected to the telescopic shell 208, and one end of the movable rod 213 located outside the telescopic shell 208 is fixedly connected to the second movable plate 214.

[0025] Specifically, if it is necessary to support the expansion of the telescopic rod mechanism 2, the first motor 302 is turned on, and the rotation of the output shaft of the first motor 302 will drive the third threaded rod 303 to rotate, thereby driving the two adjustment blocks 304 to move away from each other, and then adjusting the state of the adjustment rod 306.

The rotation of the first gear 209 will drive the second gear 210 to rotate, and then drive the second threaded rod 211 to rotate, so that the first movable plate 212 moves outward, thereby driving the movable rod 213 and the second movable plate 214 to move outward, further expanding the distance between the movable wheels 402 on both sides, so that the movable wheels 402 are against the side bottom of the semi-trailer. At this time, the second motor 403 is turned on, and the rotation of the output shaft of the second motor 403 will drive the movable wheel 402 to rotate, so as to realize the movement of the equipment along the side wall of the car body.
[0026] The rotating ring mechanism 5 includes a mounting rod 501 fixed to the side of the main body 1, and one end of the mounting rod 501 away from the main body 1 is fixedly connected to the supporting circular plate 502, and a rotating ring 503 is provided on the outside of the supporting circular plate 502, and a ring groove is provided on the inner side of the rotating ring 503, and the mounting rod 501 passes through the ring groove, and the supporting circular plate 502 and the rotating ring 503 are slidably connected, and a third motor 504 is provided on the supporting circular plate 502, and the output shaft of the third motor 504 is fixedly connected to the third gear 505, and the third gear 505 meshes with the fourth gear 506, and the fourth gear 506 is fixed to the inner side of the rotating ring 503.

[0027] Specifically, the third motor 504 is turned on, and the rotation of the output shaft of the third motor 504 will drive the third gear 505 to rotate. Since the third gear 505 and the fourth gear 506 are engaged, the rotating ring 503 can rotate relative to the supporting circular plate 502, thereby driving the laser radar 8 to rotate and change position, and the laser radar 8 can realize surround detection of the vehicle compartment.
[0028] Example 2, continue to refer to Figure 1 , Figure 2 and Figure 5In the embodiment of the present invention, the deflection mechanism 7 includes a deflection seat 701 fixed on the mounting plate 6, the deflection seat 701 is fixedly connected to the central axis 702, the central axis 702 is rotatably connected to the rotating block 703, a torsion spring 704 is fixedly connected between the rotating block 703 and the central axis 702, the rotating block 703 is fixedly connected to the fourth motor 705, the output shaft of the fourth motor 705 is fixedly connected to the rotating plate shaft 706, the rotating plate shaft 706 is fixedly connected to the rotating plate 707, and the rotating plate 707 is in contact with the outer surface of the rotating ring 503.
[0029] Specifically, under the action of the torsion spring 704, the rotating block 703 can be deflected toward the rotating ring 503, so that the rotating plate 707 is against the surface of the rotating ring 503. At this time, the fourth motor 705 is turned on, and the rotation of the output shaft of the fourth motor 705 will drive the rotating plate shaft 706 to rotate. The rotation of the rotating plate shaft 706 will drive the rotating plate 707 to rotate. Since the rotating plate 707 is in contact with the outer surface of the rotating ring 503, the mounting plate 6 can rotate around the rotating ring 503.
[0030] During the implementation of the present invention, the device is first placed in the compartment of the semi-trailer, and then the state of the connecting adjusting rod mechanism 3 is adjusted to adjust the state of the supporting telescopic rod mechanism 2, and then the spacing between the two moving wheel mechanisms 4 is adjusted, so that the moving wheel mechanism 4 is against the bottom position of the side of the semi-trailer. At this time, the laser radar 8 is turned on to measure the distance length of the position. To realize mobile detection, the moving wheel mechanism 4 is turned on to drive the laser radar 8 to move and displace. If the laser radar 8 needs to perform dimensional detection on the upper and lower and lateral directions of the compartment, the rotating ring mechanism 5 is turned on to realize the surrounding displacement of the laser radar 8. Turning on the deflection mechanism 7 can drive the mounting plate 6 to deflect and displace, and then drive the laser radar 8 to deflect and displace.
[0031] The present invention can adjust the state of the supporting telescopic rod mechanism 2 by setting a connecting adjusting rod mechanism 3, thereby adapting to the size detection of semi-trailers of different widths. The moving wheel mechanism 4 can drive the entire equipment to move, so as to perform size detection at different positions. The rotating ring mechanism 5 can drive the laser radar 8 to move around, and the deflection mechanism 7 can drive the laser radar 8 to deflect and move, thereby improving the efficiency of semi-trailer size detection.
