Specific embodiments

[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0032] Please refer to Figure 1-8 , the present utility model provides a technical solution: a road surface unevenness detection device for road surveying and mapping engineering, including a detection long plate 1, a fixed plate 2, a spirit level 3, a fixed bracket 4, a convex block 5, a fixed rod 6, a spring 7, a movable plate 8, a fixed block 9, a detection assembly 10, a movable block 11, a detection rod 12, a roller 13, a pointer 14, a connecting plate 15, a connecting rod 16 and a scale code 17.

[0033] When using the road surface unevenness detection device for road surveying and mapping engineering, first move each component of the device to the corresponding road surface unevenness detection site of the road surveying and mapping engineering, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, a spirit level 3 is installed in the middle of the upper end of the fixed plate 2, and the fixed bracket 4 is fixed to the upper end of the fixed plate 2. Fixed rods 6 are fixedly connected to both the left and right ends of the detection long plate 1. By pulling the movable plate 8, the movable plate 8 slides on the outside of the fixed rod 6 and slides between the movable plate 8 and the fixed block 9, thereby improving the stability of the movable plate 8 during movement. Moreover, the movable plate 8 squeezes the spring 7 sleeved on the outer surface of the fixed rod 6, causing the spring 7 to undergo elastic deformation. Then, the fixed bracket 4 is connected to the detection long plate 1 in a slot connection. Additionally, a convex block 5 is fixedly connected to the upper end of the fixed bracket 4. Next, the movable plate 8 is directly released. At this time, the spring 7 recovers its elastic deformation, pushing the movable plate 8 to slide between the fixed rod 6 and slide between the movable plate 8 and the fixed block 9. The upper end of the movable plate 8 is connected to the convex block 5 in a slot connection. At the same time, the upper end of the movable plate 8 is in a fitting arrangement with the upper end of the fixed bracket 4, thus facilitating the limitation between the fixed bracket 4 and the detection long plate 1 and facilitating assembly;

[0034] After assembly, place the fixed plate 2 on the road surface, measure the fixed plate 2 in combination with the spirit level 3, and adjust the position of the fixed plate 2 to make the fixed plate 2 in a horizontal state, as Figure 6 、 Figure 7 and Figure 8 shown, the detection assembly 10 is arranged in the middle of the detection long plate 1, and the detection assembly 10 includes a movable block 11 installed in the middle of the detection long plate 1 in a slot connection, a detection rod 12 telescopically connected in the middle of the movable block 11, a roller 13 rotatably installed at the lower end of the detection rod 12, a pointer 14 fixedly connected to the upper end of the detection rod 12, a vertical connecting plate 15, a connecting rod 16 fixedly connected to the upper end of the connecting plate 15, and a scale code 17 arranged on the front side of the connecting rod 16;

[0035] The roller 13 is placed on the road surface. A pointer 14 is fixedly connected to the upper end of the roller 13, and the pointer 14 points to the scale code 17. The original position value of the scale code 17 is recorded. Then, by moving the connecting rod 16, the connecting rod 16 drives the sliding between the connecting plate 15 and the detection long plate 1. At the same time, the connecting plate 15 is fixedly connected to the movable block 11, thereby driving the sliding between the movable block 11 and the detection long plate 1. At this time, the movable block 11 drives the roller 13 to roll on the road surface through the detection rod 12. The detection rod 12 and the roller 13 are affected by gravity. When the road surface is concave downward, the roller 13 moves to the concave section. At this time, the detection rod 12 telescopically moves downward in the movable block 11, thereby driving the pointer 14 to move downward, so that the position where the pointer 14 points to the scale code 17 changes, thereby detecting the scale difference between the value of the scale code 17 and the original value, and obtaining the detection data of the unevenness of the road surface. On the contrary, when the road surface protrudes upward, the roller 13 and the detection rod 12 drive the pointer 14 to move upward and point to the pointer 14. The detection method is the same. Through the above detection method, the unevenness detection of the road surface can be detected very intuitively, and the overall structure design of the device is relatively simple, which is suitable for popularization and use;

[0036] In addition, when the use is over, by disassembling between the fixed bracket 4 and the detection long plate 1, the occupied space of the device is reduced, which is convenient for handling, moving and storing, and improves the portability of the device.

[0037] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
