[0025] When detecting the height of a road surface, the height of the road rock at the edge of the road is generally used as a reference, and the measurement can be achieved by measuring the vertical distance from the top of the road rock to the ground. However, during the measurement process, the height of the ground near the road rock can only be measured, and the height of the ground far away from the road rock cannot be measured, which greatly reduces the detection range;

[0026] To do this, see Figure 1-4 The utility model provides a road surface height detection device, comprising:

[0028] Among them, the fixed structure 2 includes a slider 22 slidably connected in a slide groove provided on the inverted L-shaped seat 1, the vertical section of the slider 22 is an I-shaped structure, the bottom end of the slider 22 is fixedly connected to a clamping plate 21, and the slider 22 is threadedly connected to a screw rod 23, both ends of the screw rod 23 are rotatably connected in the slide groove, and the end of the screw rod 23 away from the front side wall of the inverted L-shaped seat 1 extends to the outside of the inverted L-shaped seat 1, and is fixedly connected to a handle 24. The setting of the spring a35 can ensure that the roller 34 can continue to overlap and roll with the ground when the ground is uneven, and the top of the rotating rod is flush with the inner top wall of the inverted L-shaped seat 1, so that the top of the rotating support rod 31 is flush with the top height of the roadside rock. In addition, the top of the moving seat 32 is also flush with the top of the rotating support rod 31. Combined with the setting of the indicator block 37 and the scale line 36, it is convenient to read the ground height.

[0029] It also includes a locking assembly and a clamping structure 4, the locking assembly is installed on the front side wall of the rotating support rod 31 and is connected to the moving seat 32, and the locking assembly can lock the moving seat 32 after the position is manually moved and adjusted on the rotating support rod 31;

[0030] The clamping structure 4 is installed on the connecting shaft 3 and connected to the front side wall of the inverted L-shaped seat 1 . The clamping structure 4 can facilitate the adjustment of the angle of the rotating support rod 31 .

[0031] Further as Figure 4 As shown, it is worth explaining in detail that the vertical section of the movable seat 32 is an I-shaped structure.

[0032] Further as Figure 1-4 As shown, it is worth explaining in detail that the locking assembly includes a stud 38 fixed to the middle of the outer wall of one side of the movable seat 32, and a moving channel for facilitating the movement of the stud 38 is opened on the front side wall of the rotating support rod 31. The moving channel is connected to the moving groove, and one end of the stud 38 passes through the moving channel and is threadedly connected with a hand nut 39.

[0033] The width of the moving channel is equal to the diameter of the stud 38 .

[0034] Further as Figure 1-4 As shown, it is worth explaining in detail that in order to facilitate the fixation of the rotating support rod 31 after rotating and adjusting the angle, a clamping structure 4 is set, including a blocking block 41 fixed to the top of the connecting shaft 3, and the bottom end of the blocking block 41 is connected to a spline sleeve 43 through a spring b45. A plurality of key strips 42 fixed to the outside of the connecting shaft 3 are provided between the bottom of the blocking block 41 and the top of the rotating support rod 31. The plurality of key strips 42 are arranged in a circular array, and the spline sleeve 43 is slidably sleeved on the plurality of key strips 42 and the outside of the connecting shaft 3.

After the movement is completed, the hand-tightening nut 39 can be locked. Thereafter, the spline sleeve 43 connected to the gear 44 can be manually pulled to move up on the outer sides of the multiple key strips 42 and the connecting shaft 3, and the spring b45 can be compressed to make the gear 44 disengage from its teeth 46. At this time, the connecting shaft 3 can be manually driven to rotate and support The rod 31 rotates to cooperate with the rolling of the roller 34, so that the road surface height with the connecting shaft 3 as the axial distribution can be detected, and the detected height can be observed through the indicator block 37 combined with the scale line 36. In summary, the position of the movable seat 32 is adjustable and lockable, and the rotating support rod 31 can be rotated through the connecting shaft 3, so that the road surface height detection range is wide, and in the detection process, the inverted L-shaped seat 1 is always fixed on the road rock at one time, without the need for multiple disassembly and fixed installation, which greatly improves the detection accuracy and efficiency.
