[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0029] Please see the appendix Figures 1-7 This utility model discloses a highway foundation collapse monitoring device, including a traction seat 1, a bearing mechanism 2, and a monitoring mechanism 3, wherein:

[0030] The traction seat 1 is symmetrically equipped with movable wheels 11 at both ends, and a traction frame 12 for connecting to the traction vehicle is installed at the front end of the traction seat 1.

[0031] The bearing mechanism 2 includes a rotatable mounting base 22 symmetrically arranged at the rear end of the traction seat 1, and a plurality of casters 24 are mounted on the bottom of the mounting base 22;

[0032] The monitoring mechanism 3 includes multiple monitoring feet 35 fixed in the mounting base 22 for monitoring roadbed collapse.

[0033] Please refer to the appendix. Figure 1 , Figure 4 The bearing mechanism 2 also includes a rotating frame 21 fixed to the front end of the mounting base 22. The rotating frame 21 is located at the upper end of the traction seat 1. Fixed shafts 14 are symmetrically installed at the upper end of the traction seat 1. The fixed shafts 14 pass through the rotating frame 21 and are rotatably connected to the rotating frame 21.

[0034] Specifically, the mounting base 22 can be horizontally rotated and unfolded to both sides of the traction seat 1 or merged to the rear end of the traction seat 1 via the fixed shaft 14. In the unfolded state, the monitoring feet 35 inside the mounting base 22 can monitor a large area of ​​the roadbed. In the merged state, the lateral volume of the mounting base 22 is reduced, which facilitates transportation.

[0035] Please refer to the appendix. Figures 1-4 The upper end face of the traction seat 1 is symmetrically provided with fixed pile holes 13 at the position between the fixed shafts 14. The front end of the rotating frame 21 is equipped with a fixed plate 211. The middle part of the fixed plate 211 is provided with a limiting pile 212 that penetrates the fixed plate 211 and is movable. The limiting pile 212 is movably connected to and cooperates with the fixed pile holes 13.

[0036] Furthermore, a connecting plate 4 is provided on the top of the side of the symmetrically arranged mounting base 22 that is in contact with each other. The connecting plate 4 is fixed to the upper end of the symmetrically arranged mounting base 22 by connecting bolts 41 and connects the two mounting bases 22.

[0037] Specifically, the installation base 22 in the unfolded state is fixed by the limiting stake 212 to keep the installation base 22 in the unfolded state, and the installation base 22 in the folded state is fixed by the connecting plate 4 to keep the position of the installation base 22 fixed and prevent the installation base 22 from unfolding during transportation.

[0038] Please refer to the appendix. Figure 6 Multiple vertical displacement sensors 31 are installed inside the mounting base 22 via mounting bracket 32. A lifting column 34 is movably connected inside the displacement sensor 31. The bottom of the lifting column 34 is fixedly connected to the monitoring foot 35. A roller 36 is installed at the bottom of the monitoring foot 35.

[0039] Furthermore, the monitoring foot 35 is hollow inside, and multiple stacked counterweights 37 are installed in the hollow area.

[0040] Specifically, the monitoring foot 35 moves on the roadbed via the roller 36. When the road passes a collapse, the monitoring foot 35 descends, causing the lifting column 34 to descend. When the lifting column 34 descends, it is detected and identified by the displacement sensor 31, which can directly detect the value of the descent, thus accurately monitoring the roadbed collapse. Example 2

[0041] Based on the above embodiment one, please refer to the appendix. Figure 4 , Figure 5 The mounting base 22 has multiple upward-facing electric push rods 25 embedded in its upper end. The output end of each electric push rod 25 is fixed with a protective plate 23. The top of the lifting column 34 is equipped with a connecting plate 33, which is fixedly connected to the bottom of the protective plate 23.

[0042] Furthermore, a connecting column 341 is provided at the top of the lifting column 34, and a telescopic rod 342 is installed at the upper end of the lifting column 34. The top of the connecting column 341 is fixedly connected to the connecting plate 33. A telescopic groove 344 is provided inside the connecting column 341. The telescopic rod 342 passes through the connecting column 341 and extends into the telescopic groove 344, and a limiting plate 343 is installed that is movably connected to and fits into the telescopic groove 344. The two sides of the protective plate 23 are flush with the two sides of the mounting base 22. The top of the protective plate is provided with a drainage groove 231 that slopes downward toward the two sides of the protective plate 23.

[0043] In this embodiment, when no monitoring operation is being performed, the electric push rod 25 drives the protective plate 23 to move upward. The protective plate 23 drives the connecting column 341 to move upward through the connecting plate 33. The connecting column 341 drives the lifting column 34 to move upward. The upward movement of the lifting column 34 in turn drives the monitoring foot 35 and the roller 36 to move upward, keeping the roller 36 suspended in the air and preventing the roller 36 from rolling and wearing on the road surface during transportation. When monitoring operations encounter rain or snow, the protective plate 23 can shield and protect the electric push rod 25, displacement sensor 31 and other equipment.

[0044] The working principle and usage process of this utility model are as follows: When transporting this device, the two mounting bases 22 are combined at the rear end of the traction seat 1, and the mounting bases 22 are fixed together by the connecting plate 4. At this time, the electric push rod 25 is kept in the extended state so that the roller 36 at the bottom of the monitoring foot 35 is kept suspended. After the traction seat 1 is connected to the traction vehicle by the traction frame 12, the device can be transported. During the transportation process, the suspended roller 36 does not contact the ground.

[0045] During monitoring operations, firstly, the connecting bolts 41 are unscrewed and the connecting plate 4 is removed. Then, the two mounting bases 22 are horizontally rotated to both sides of the traction seat 1 via the universal wheels 24 and the fixed shaft 14, and the two mounting bases 22 are aligned parallel to each other. At this time, the limiting stake 212 is inserted from top to bottom through the fixed plate 211 and then inserted into the fixed stake hole 13 on the traction seat 1 to fix the position of the mounting base 22. After the traction seat 1 is connected to the traction vehicle via the traction frame 12, the electric push rod 25 is controlled to retract, causing the protective plate 23 to move downward. Then, the monitoring foot 35 is driven downward through the connecting column 341 and the lifting column 34, so that the roller 36 contacts the ground. At this time, under the drive of the traction vehicle, the entire device moves and monitors on the roadbed. When it moves to the collapse point, the monitoring foot 35 and the roller 36 descend and drive the lifting column 34 to descend. When the lifting column 34 descends, it is detected and identified by the displacement sensor 31, and the displacement sensor 31 can directly detect the value of the descent, so as to accurately monitor the roadbed collapse.
