The lower end of the rotating tube 11 is connected to a sampling tube 12, and an adsorption device 2 is provided in the sampling tube 12, and the adsorption device 2 is used to adsorb cement column samples.

[0020] like Figure 2-3 As shown, the adsorption device 2 includes a circular tube 21, which is located in the rotating tube 11. The lower end of the circular tube 21 is connected to the rubber suction cup 22. A piston 23 slides on the inner wall of the circular tube 21. The upper surface of the piston 23 is fixedly connected to a vertical rod 24, and the upper end of the vertical rod 24 is fixedly connected to a circular block 25.

[0021] like Figure 2-3As shown, the upper surface of the support plate 1 is fixedly connected to the vertical plate 26, and a slide groove is provided on one side of the vertical plate 26, and a sliding plate 27 is slidably connected in the slide groove, and the sliding plate 27 can slide up and down along the vertical plate 26. A threaded hole is provided on one side of the sliding plate 27. After the sliding plate 27 slides to a certain position, the fastening screw 291 can be screwed in so that the fastening screw 291 and the side wall of the vertical plate 26 are frictionally locked to prevent the sliding plate 27 from moving down. A circular through groove is provided on the other side of the sliding plate 27, and the round tube 21 is fixed on the circular through groove. The vertical plate 28 is fixedly connected to the left side of the upper end surface of the sliding plate 27, and the horizontal plate 29 is fixedly connected to the vertical plate 28. The horizontal plate 29 is provided with a threaded through hole, and the vertical rod 24 is provided with a thread, and the vertical rod 24 is threadedly connected to the horizontal plate 29.

[0022] like Figure 1-2 As shown, the driving assembly 3 includes a driving motor 31, and the driving motor 31 is fixedly connected to the support plate 1. The outer circle of the rotating tube 11 is fixedly connected to the gear ring 32, and the main shaft of the driving motor 31 is fixed to the gear 33, and the gear 33 is meshed with the gear ring 32. In addition, two hydraulic rods 34 are fixedly connected to the support plate 1, and the lower ends of the hydraulic rods 34 are fixedly connected to the counterweight block 35, and the lower ends of the two counterweight blocks 35 are fixedly connected to the anti-sliding block 36, and the lower surfaces of the two anti-sliding blocks 36 are provided with anti-skid grooves 37. The counterweight block 35 presses down the anti-sliding block 36, so that the two anti-sliding blocks 36 are in close contact with the concrete bridge deck. At the same time, under the action of the anti-skid groove 37, the whole device is more stable to prevent the device from moving due to vibration.

[0023] Working principle and process:

[0024] 1) Transport the equipment to the sampling point, wet the road surface, and make the two anti-sliding blocks 36 closely contact the concrete bridge deck; start the driving motor 31, and drive the sampling tube 12 to rotate through the gear 33 and the gear ring 32 to cut the concrete bridge deck, and then the two hydraulic rods 34 contract to make the support plate 1 and the sampling tube 12 descend, so that the sampling tube 12 gradually extends into the concrete bridge deck, and a concrete sample column is formed inside the sampling tube 12.

[0025] 2) Then, push the sliding plate 27 downward to make the rubber suction cup 22 contact the upper surface of the concrete sample column, so that the rubber suction cup 22 presses the upper surface of the concrete sample column downward to exhaust the air. Then, turn the vertical rod 24 to make the vertical rod 24 rise and pull the piston 23 upward, so that the space between the concrete and the round tube 21 is in a vacuum state, making the suction force between the rubber suction cup 22 and the concrete sample column stronger. Screw in the fastening screw 291 to fix the position of the sliding plate 27.

[0026] 3) Finally, the two hydraulic rods 34 extend, and at this time, while the sampling tube 12 rises, the rubber suction cup 22 lifts the concrete sample column upward, so that the concrete sample column leaves the sampling hole. Then, the device is moved to the side of the sampling hole, the vertical rod 24 is rotated downward, and the piston 23 moves down to the rubber suction cup 22. The piston 23 continues to move downward for a few millimeters to push the concrete sample column, so that the concrete sample column is separated from the rubber suction cup 22.
