By increasing the number or length of the adjustment sub-boards, the flatness detection of roads of different lengths can be adapted, and by adjusting the length of the sub-boards, a wider road surface area can be covered, thereby improving the flexibility and applicability of the device.

[0008] Furthermore, the adjustment mechanism includes a supporting sleeve, an electric push rod is provided at the bottom of the supporting sleeve, the telescopic end of the electric push rod is fixedly connected to a connecting rod, and the connecting rod is detachably connected to a connecting plate. After the staff holds the supporting sleeve, the telescopic electric push rod will drive the connecting plate to move up and down to achieve height adjustment of the entire device, thereby enabling the detection mechanism to contact the road surface and achieve measurement of the road surface flatness.

The components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0025] Therefore, the following detailed description of the embodiments of the utility model provided in the accompanying drawings is not intended to limit the scope of the utility model claimed for protection, but merely represents selected embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-3 As shown, in the embodiment of the utility model, a road surface flatness detection device includes an adjustment main board 1, a connecting plate 2 is arranged on the adjustment main board 1, an adjustment mechanism 3 is arranged on the connecting plate 2, a vertical scale 111 is arranged on the adjustment main board 1, and a plurality of adjustment sub-boards 4 are detachably connected to both sides of the adjustment main board 1, and a detection mechanism 5 is arranged on the plurality of adjustment sub-boards 4; the adjustment mechanism 3 is arranged on the adjustment main board 1 for adjusting the height of the entire device,

[0027] Several adjustment sub-plates 4 are connected end to end to each other and can be detachably connected on both sides of the adjustment main plate 1. The detection length of the entire device can be adjusted to adapt to the flatness detection of road surfaces of different lengths. During the detection process, the detection mechanism 5 on each adjustment sub-plate 4 measures the height of different positions under the road surface of that length. Through multiple detection mechanisms 5, the height difference under the road surface is judged, and then the flatness of the road surface is obtained. By increasing the number or length of the adjustment sub-plates 4 on both sides of the adjustment main plate 1, it is possible to adapt to the flatness detection of roads of different lengths and cover a wider road surface area, thereby improving the flexibility and applicability of the device.

[0028] In one embodiment, see Figure 1 and Figure 2As shown, first card slots 11 are provided on both sides of the adjustment main board 1, and adjustment sub-boards 4 are clamped on both sides of the two first card slots 11. The two adjacent adjustment sub-boards 4 are detachably connected to each other. There is a first card slot 11 on both sides of the adjustment main board 1, and each first card slot 11 is used to connect an adjustment sub-board 4. Each adjustment main board 1 can be connected to two adjustment sub-boards 4 to form a complete device. Two adjacent adjustment sub-boards 4 can be connected to each other, and this connection is detachable. Since the connection between the adjustment sub-boards 4 is detachable, the user can increase or decrease the number of adjustment sub-boards 4 as needed to adapt to different lengths and types of road surfaces.

[0029] In one embodiment, see Figure 1 and Figure 2 As shown, a clamping portion 411 is provided on one side of the adjustment sub-plate 4, and a second clamping groove 412 is provided on the side of the adjustment sub-plate 4 away from the clamping portion 411. The sizes of the clamping portion 411 and the second clamping groove 412 match each other, and the head and tail of two adjacent adjustment sub-plates 4 are clamped to each other. The head and tail connection of the two adjustment sub-plates 4 is completed by clamping the clamping portion 411 at the head of one adjustment sub-plate 4 into the second clamping groove 412 at the tail of the other adjustment sub-plate 4. The number of adjustment sub-plates 4 can be increased or decreased as needed to meet the flatness requirements of road surfaces of different lengths.

[0030] In one embodiment, see Figure 1 and Figure 2 As shown, the adjustment mechanism 3 includes a supporting sleeve 31, and an electric push rod 32 is arranged at the bottom of the supporting sleeve 31. The telescopic end of the electric push rod 32 is fixedly connected with a connecting rod 33, and the connecting rod 33 is detachably connected to the connecting plate 2. The connecting plate 2 is a platform for connecting other parts of the device, supporting the structure of the entire device, and is fixed to the end of the electric push rod 32 through the connecting rod 33. When the telescopic end of the electric push rod 32 moves, the connecting plate 2 will move up and down accordingly, so as to realize the height adjustment of the whole device, so that the detection mechanism 5 can contact the road surface and realize the measurement of the road surface flatness.

[0031] In one embodiment, see Figure 1 , Figure 2 and Figure 3 As shown, the detection mechanism 5 includes a detection rod body 51, which is slidably connected to the adjustment sub-plate 4, a marking rod 52 is arranged above the detection rod body 51, a mounting plate 54 is arranged at the bottom end of the detection rod body 51, a buffer spring 53 is sleeved on the detection rod body 51, and the buffer spring 53 is arranged between the mounting plate 54 and the adjustment sub-plate 4, a detection frame 55 is arranged on the mounting plate 54, and a contact wheel 56 is detachably connected to the detection frame 55;

[0032] The contact wheel 56 contacts the road surface and is affected by the changes in the height of the road surface. The contact wheel 56 is squeezed to drive the detection rod body 51 to slide. The squeezing effect of the contact wheel 56 will drive the detection rod body 51 to slide on the adjustment sub-plate 4. This sliding process enables the detection rod body 51 to move up and down following the changes in the height of the road surface and slide a certain distance on the marking rod 52. The sliding of the detection rod body 51 causes the marking rod 52 to move accordingly. The indicator needle 6 on the marking rod 52 can record the moving distance of the marking rod 52 relative to the adjustment sub-plate 4. According to the moving distance of the marking rod 52, the height change of the ground can be determined, and the flatness of the road surface at that location can be displayed through the height changes of each marking rod 52.

[0033] In one embodiment, see Figure 1 and Figure 3 As shown, the setting of the indicator needle 6 is provided on the marking rod 52, and its function is to provide an indicating device for the operator to facilitate reading and observing the ground height reading. The indicator needle 6 can move along the scale or indicator line of the marking rod 52 to reflect the change of the ground height. When the device is used, the operator can read the scale corresponding to the indicator needle 6 on the marking rod 52 on the vertical scale 111 by observing the position of the indicator needle 6, and then display the height of the road surface, so that the operator can accurately understand the height of the ground at that location.

[0034] In one embodiment, see Figure 1 and Figure 3 As shown, the indicator needle 6 is detachably connected to the marking rod 52, so that the staff can disassemble and replace the entire indicator needle 6 conveniently.

[0035] In one embodiment, see Figure 1 and Figure 2 As shown, the support sleeve 31 is provided with anti-slip grooves, which makes it convenient for staff to take the entire support sleeve 31 and to grasp the support sleeve 31 .

The technicians in this technical field may make various modifications or additions to the specific embodiments described or replace them in a similar manner. As long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of the utility model.
