One side surface of the compression spring 9 is fixedly connected, a rectangular hole 11 connected to the rectangular cavity 8 is opened on the surface of the No. 1 connecting plate 3 away from the upper plate 1, and the No. 2 connecting plate 4 is located in the rectangular hole 11, and the surface of the No. 2 connecting plate 4 is in sliding contact with the inner surface of the rectangular hole 11, which is convenient for the No. 2 connecting plate 4 to telescopically move in the rectangular cavity 8, and the outer shape of the fixed plate 10 is adapted to the inner shape of the rectangular cavity 8, and the surface of the fixed plate 10 is in sliding contact with the inner surface of the rectangular cavity 8, which is convenient for the fixed plate 10 to move in the rectangular cavity 8, and the number of the telescopic springs 9 is three, and the spacing between two adjacent telescopic springs 9 is equal;

[0023] The thickness detection mechanism includes a controller 5 fixedly mounted on the upper surface of the upper plate 1, a laser rangefinder 6 fixedly mounted on the lower surface of the upper plate 1, a laser receiver 7 fixedly mounted on the upper surface of the lower plate 2, the laser rangefinder 6 is located directly above the laser receiver 7, the laser rangefinder 6 and the laser receiver 7 are electrically connected to the controller 5, two moving rollers 12 are fixedly mounted on the surfaces of the upper plate 1 and the lower plate 2 on opposite sides, the moving rollers 12 on the upper plate 1 correspond to the moving rollers 12 on the lower plate 2, so as to facilitate the movement of the detection mechanism on the concrete slab, the surface of the moving roller 12 on the upper plate 1 is flush with the surface of the laser rangefinder 6 away from the upper plate 1, and the surface of the moving roller 12 on the lower plate 2 is flush with the surface of the laser receiver 7 away from the lower plate 2.

[0024] The working principle of the above embodiment is:

[0025] When in use, the lower plate 2 is pulled downward, and the lower plate 2 moves downward while driving the second connecting plate 4 downward. The second connecting plate 4 moves downward while driving the fixed plate 10 to move downward in the rectangular cavity 8. The fixed plate 10 moves downward while pulling the telescopic spring 9 until the spacing between the moving rollers 12 on the upper plate 1 and the lower plate 2 is greater than the thickness of the concrete structure to be detected. The concrete structure is placed between the upper plate 1 and the lower plate 2, and the lower plate 2 is released. At this time, the telescopic spring 9 loses its restraint and contracts. When the telescopic spring 9 contracts, it drives the fixed plate 10 to move upward in the rectangular cavity 8, and then the fixed plate 10 drives the second connecting plate 4 to contract into the rectangular cavity 8, so that the upper surface of the concrete structure contacts the surface of the moving roller 12 on the upper plate 1, and the lower surface of the concrete structure contacts the surface of the moving roller 12 on the lower plate 2. The laser rangefinder 6 and the laser receiver 7 are started by the controller 5. The laser rangefinder 6 emits a laser, and the laser receiver 7 receives the laser emitted by the laser rangefinder 6. The laser receiver 7 converts the received laser signal into an electrical signal and displays it on the controller 5.
