[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.
[0020] The utility model provides a technical solution: Figure 1 - Figure 4 As shown, in this embodiment, a flatness detection device for a large cross-slope curve includes a support rod 1, one side of the support rod 1 is fixedly connected to a mounting cylinder 20, the inner wall of the mounting cylinder 20 is rotatably connected to a rotating shaft 17, a steering groove 23 is provided inside the support rod 1, one side of the inner wall of the steering groove 23 is rotatably connected to a bevel gear 2 18, one side of the bevel gear 2 18 is fixedly connected to one end of the rotating shaft 17, the outer surface of the bevel gear 2 18 is meshed with a bevel gear 16, one side of the bevel gear 16 is fixedly connected to a threaded rod 2 15, one end of the threaded rod 2 15 is rotatably connected to a sliding rod 2, the outer side wall of the sliding rod 2 is slidably connected to the inner wall of the support rod 1, and one side of the outer side wall of the sliding rod 2 is fixedly installed with a remote A data collection box 5 is fixedly installed on the other side of the support rod 1 away from the long-range laser radar scanning device 3. By placing the support rod 1 near the large cross-slope curve and rotating the rotating shaft 17, the bevel gear 16 drives the threaded rod 2 15 to rotate in the support rod 1, and the sliding rod 2 moves upward, the long-range laser radar scanning device 3 is moved to a high place, and the long-range laser radar scanning device 3 is turned on to detect the surface of the large cross-slope curve, and the detected data is transmitted to the data collection box 5, so that the flatness detection of the large cross-slope curve is completed. This structure is simple and easy to operate, which improves the detection efficiency of the flatness of the large cross-slope curve, wherein a signal transmission device is installed in the data collection box 5 and the long-range laser radar scanning device 3.
[0021] like Figure 3 and Figure 4 As shown, one side of the mounting tube 20 is fixedly connected to a connecting ring 21, and the other end of the rotating shaft 17 is fixedly connected to a hexagonal connecting rod 19. The outer wall of the hexagonal connecting rod 19 is slidably connected to a hexagonal fixing ring 22. One side of the hexagonal fixing ring 22 is slidably engaged with the inner wall of the connecting ring 21. Through the cooperation between the connecting ring 21 and the hexagonal fixing ring 22, the hexagonal fixing ring 22 is pushed and clamped in the connecting ring 21, thereby limiting the rotation of the hexagonal connecting rod 19.
[0022] like Figure 1 and Figure 3 As shown, a guide groove 14 is provided on the inner wall of the support rod 1, and a slide bar 13 is fixedly connected to the outer wall of the sliding rod 2. The outer wall of the slide bar 13 is slidably connected to the inner wall of the guide groove 14. The cooperation between the guide groove 14 and the slide bar 13 prevents the sliding rod 2 from rotating inside the support rod 1 when the threaded rod 15 rotates.

One side of the rotating bracket 7 is threadedly connected to a fixing nut 9, and one end of the fixing nut 9 is clamped with one side of the outer wall of the support bracket 8. Through the design between the rotating bracket 7, the support bracket 8 and the fixing nut 9, the support rod 1 can be supported, and the volume of the equipment can be reduced when in use.

A threaded rod 12 is rotatably connected to one side of the top rod 11. One side of the outer wall of the threaded rod 12 is threadedly connected to one side of the L-shaped fixing bracket 10. When the long-range laser radar scanning device 3 is moved to the top, the threaded rod 12 is rotated, and the top rod 11 slides on the L-shaped fixing bracket 10, and one end of the top rod 11 is stuck in the groove of the sliding rod 2 to fix the sliding rod 2, thereby preventing the equipment on the sliding rod 2 from being too heavy and causing the sliding rod 2 to slide down in the support rod 1, resulting in a smaller detection range.
[0026] The utility model provides a flatness detection device for steep slope curves, and the specific working principle is as follows:
[0027] When testing the flatness of a large cross-slope curve, first place the support rod 1 near the large cross-slope curve, loosen the fixing nut 9, adjust the support frame 8 to the appropriate distance, tighten the fixing nut 9, rotate the rotating frame 7, so that the support frame 8 supports the equipment, and then rotate the rotating shaft 17 to make the bevel gear 16 drive the threaded rod 2 15 to rotate in the support rod 1, and move the sliding rod 2 upward. When moving the long-range laser radar scanning equipment 3 to a higher place, push the hexagonal fixing ring 22, and clamp one side of the hexagonal fixing ring 22 in the connecting ring 21, connect the hexagonal connecting rod 19 to the connecting ring 21, turn on the long-range laser radar scanning equipment 3, and detect the surface of the large cross-slope curve. The detected data is transmitted to the data collection box 5, thereby completing the flatness detection of the large cross-slope curve.
[0028] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
