[0031] In the present invention, when the height difference detection is performed on the manhole on the road surface, the device is moved to the manhole, the detection frame 4 is pushed out from the horizontal support frame 3, and the movable platform 9 is moved downward by the detection frame 4 so that the movable platform 9 is located above the manhole frame. At this time, the positioning mechanism 7 is in the maximum stroke state, the movable platform 9 continues to move downward, the bottom of the positioning mechanism 7 contacts the surface of the manhole cover, and the driving mechanism 6 drives the height difference detection mechanism 10 to expand outward synchronously. When the bottom end of the positioning mechanism 7 contacts the inner circle of the manhole frame, the movable platform 9 and the detection platform 8 are automatically pushed to the same center position as the manhole cover. At this time, the detection platform 8 is in the height difference detection position, the outermost height difference detection component is located on the road surface, and the innermost height difference detection component is located on the manhole cover. The height difference detection component in the middle sequentially spans the road surface, the manhole frame and the outer area of ​​the manhole cover, and then the positioning mechanism 7 shrinks to the minimum stroke, and the movable stand 9 and the detection platform 8 move downward to enter the manhole frame and road surface height difference detection process. The multi-layered height difference detection components fall on the road surface, the manhole frame and the manhole cover in turn, and the reading component reads the spacing changes of the up and down activities of the height difference detection components to quickly obtain the height difference between the road surface, the manhole frame and the manhole cover.

During the calibration, the movable stand 9 and the detection platform 8 are adjusted to a horizontal position through the height adjustment mechanism 5, and the detection program is entered. The height difference detection component and the reading component signals are detected on the horizontal road surface, and the protection height is determined by adjusting the height of the limit foot 53 to avoid damage to the height difference detection component during the detection process.

[0034] As a further solution in the present invention, the movable platform 9 includes two semicircular ring hoops 91, and a shell 93 is provided on the side of the ring hoop 91.

In the present invention, the movable platform 9 and the detection platform 8 move downward to enter the well frame and road surface height difference detection process, and the multi-layered height difference detection components fall on the road surface, the well frame and the manhole cover in turn. After that, the servo motor 92 drives the detection platform 8 to rotate, and then the multiple rows of height difference detection components perform a circular motion at the well frame to obtain the overall height difference data of the road surface, the well frame and the manhole cover, thereby improving the accuracy of the road surface and well frame construction quality detection.

In the present invention, when the movable stand 9 and the inspection platform 8 are positioned above the manhole frame, the electric push rod 71 is in the maximum stroke state, and the bottom end of the fitting ring 73 is located 1-2CM below the height difference detection component. When the fitting ring 73 contacts the surface of the manhole cover and moves outward, the fitting ring 73 contacts the inner circle of the manhole frame and generates thrust on the movable stand 9 and the inspection platform 8. The ring-shaped positioning mechanism 7 is used to push the movable stand 9 and the inspection platform 8 to the same center position as the manhole frame, thereby completing the operation of determining the detection position of the movable stand 9 and the inspection platform 8. The detection position positioning is simple and convenient, thereby improving the efficiency of the manhole frame and road surface height difference detection.

The height difference detection component contacts the surface of the road surface, the well frame and the manhole cover through the detection ball 103 at the bottom, and rolls on the surface of the road surface, the well frame and the manhole cover, and relies on the thrust of the limit spring 104 to maintain the tightness of the connection between the detection ball 103 and the road surface, the well frame and the manhole cover surface, and during the rotation process, it telescopes and moves with the height difference of the road surface, the well frame and the manhole cover surface to quickly obtain height difference information.

The electronic ruler sensor 106 is sleeved on the outer side of the electronic ruler 105. In the present invention, the electronic ruler 105 is on the detection slide bar 102. As the height difference of the road surface, the well frame and the well cover changes, the electronic ruler 105 moves inside the electronic ruler sensor 106 to obtain the height difference information of the road surface, the well frame and the well cover, and transmits it to the controller for storage, so as to record the detection data in real time and improve the accuracy and convenience of the well frame and road surface height difference detection.

At this time, the positioning mechanism 7 is in the maximum stroke state, the movable stand 9 continues to move downward, the bottom of the positioning mechanism 7 contacts the surface of the manhole cover, and the driving mechanism 6 drives the height difference detection mechanism 10 to expand outward synchronously. When the bottom end of the positioning mechanism 7 contacts the inner circle of the manhole frame, the movable stand 9 and the detection platform 8 are automatically pushed to the same center position as the manhole cover. At this time, the detection platform 8 is in the height difference detection position, and the outermost height difference detection component The innermost height difference detection component is located on the road surface, and the height difference detection component in the middle sequentially spans the road surface, the manhole frame and the outer area of ​​the manhole cover. Then the positioning mechanism 7 shrinks to the minimum stroke, and the movable stand 9 and the detection platform 8 move downward to enter the manhole frame and road surface height difference detection process. The multi-layered height difference detection components fall on the road surface, the manhole frame and the manhole cover in turn. The reading component reads the change in the spacing between the up and down activities of the height difference detection components to quickly obtain the height difference between the road surface, the manhole frame and the manhole cover.
