The lifting rod 4 is movably installed through the bracket 1 and can move in the vertical direction. The first cylinder 3 is fixedly installed on the bracket 1, and the movable end of the first cylinder 3 is fixedly connected to the end cap 5. The end cap 5 is also fixedly connected to the top of the lifting rod 4. When the first cylinder 3 is working, it can drive the end cap 5 and the lifting rod 4 to move. One end of the guide rod 6 is fixedly installed on the bracket 1, and the other end passes through the end cap 5. When the end cap 5 moves with the first cylinder 3, the guide rod 6 can play a guiding role. A scale 24 is provided at the lower part of the lifting rod 4, and a fixing plate 7, a rotating device 8 and an adjusting device 9 are also installed.

[0023] like Figure 1-2As shown, the fixed plate 7 is fixedly mounted on the lifting rod 4 and moves with the lifting rod 4. The adjusting device 9 includes a second cylinder 10, which is fixedly mounted on the fixed plate 7. The movable end of the second cylinder 10 is connected to a crossbar 11, which is plugged into the side of a turntable 13, and the turntable 13 is mounted on the lifting rod 4. When the second cylinder 10 is working, it can drive the crossbar 11 and the turntable 13 to move vertically along the lifting rod 4. The turntable 13 includes a fixed end and a rotating end, and the rotating end has a built-in bearing so that it can rotate around the fixed end. The crossbar 11 is plugged into the fixed end part of the turntable 13, and a limiting column 12 is installed on the crossbar 11. The limiting column 12 is located in an annular limiting groove 14 processed on the rotating end of the turntable 13. When the rotating end of the turntable 13 rotates, the limiting column 12 can slide in the limiting groove 14. A camera 25 is installed at the lower part of the rotating end of the turntable 13, and the camera 25 is connected to the control console 2 by electrical signals. The camera 25 can capture the scale 24 and transmit the captured scale signal to the control console 2 for the convenience of the staff to check and record. A slot plate 15 is installed on the side of the rotating end of the turntable 13, and a second support rod 16 is hinged in the slot plate 15 through an axis.

[0024] like Figure 1 and 3 , the rotating device 8 is located at the bottom of the lifting rod 4 and is connected to the adjusting device 9. The rotating device includes a chassis 19, which is movably installed at the bottom of the lifting rod 4 and can rotate the lifting rod 4. A bottom column 20 is fixedly connected to the inner wall of the bottom end of the chassis 19, and the bottom column 20 is located at the bottom center of the chassis 19. A second gear 21 is provided on the bottom column 20, and a micro motor 22 is fixedly installed on the bottom end surface of the lifting rod 4. The output end of the micro motor 22 is installed with a first gear 23, and the first gear 23 is meshed and connected with the second gear 21, and the chassis 19 is driven to rotate through the micro motor 22 through gear transmission. A first support rod 17 is hinged on the outer side of the chassis 19, and a roller 18 is provided at the end of the first support rod 17. The first support rod 17 is hinged with the second support rod 16. When the second cylinder 10 drives the turntable 13 to perform lifting and lowering movements, the second support rod 16 can push the first support rod 17 to swing, adjust the distance from the roller 18 to the lifting rod 4, and then adapt to the detection of different pile hole diameters. The scale 24 on the lifting rod 4 marks the horizontal distance from the roller 18 to the lifting rod 4, that is, the value of the pile hole radius to be measured. When the micro motor 22 drives the chassis 19 to rotate, the chassis 19 can drive the first support rod 17 to rotate, so that the orientation of the roller 18 can be rotated and adjusted.
