[0024] Specifically, start the motor 3. The output end of the motor 3 drives the first rotating shaft 4 to rotate. The rotation of the first rotating shaft 4 drives the first roller shaft 5 to rotate. The rotation of the first roller shaft 5 drives the conveyor belt 6 to rotate.

The output end of the hydraulic rod 14 drives the sliding table 2 to lift and lower. The lifting and lowering of the sliding table 2 drives the slide rail 11 to lift and lower. The lifting and lowering of the slide rail 11 drives the sliding block 9 to lift and lower. The lifting and lowering of the sliding block 9 drives the clamping block 10 to lift and lower. When the clamping block 10 is in the clamping state, it will drive the pile to rise, completing the extraction of the pile.
[0025] Refer to Figures 1-3 , the rotating assembly includes a worm 15. The middle outer wall of the worm 15 is rotatably connected to the rear inner wall of the sliding block 9. A turntable 16 is fixedly connected to the rear outer wall of the worm 15. The middle outer wall of the worm 15 is rotatably connected to a fixed block 17.

[0026] Specifically, rotate the turntable 16. The rotation of the turntable 16 drives the worm 15 to rotate. The rotation of the worm 15 drives the worm gear 18 to rotate. The rotation of the worm gear 18 drives the second rotating shaft 19 to rotate. The rotation of the second rotating shaft 19 drives the gear 20 to rotate. The rotation of the gear 20 drives the rack 21 to lift and lower. The lifting and lowering of the rack 21 drives the limiting block 22 to lift and lower. The limiting block 22 is completely inserted downward into the limiting groove 23, completing the fixation of the sliding block 9 and the clamping block 10. The limiting block 22 moves upward away from the limiting groove 23, completing the separation of the sliding block 9 and the clamping block 10, and the clamping block 10 can be replaced.
[0027] Refer to Figure 1 and Figure 2 , the right outer wall of the first rotating shaft 4 is arranged on the right inner wall of the housing 1. The middle outer wall of the bidirectional lead screw 8 is rotatably connected to the front inner wall of the sliding table 2.

The outer wall of the ball 13 is arranged on the right inner wall of the housing 1. The output end of the hydraulic rod 14 is fixedly connected to the lower surface of the sliding table 2.
[0028] Specifically, the outer shell 1 supports the first rotating shaft 4, and the first rotating shaft 4 rotates within the outer shell 1. The sliding table 2 supports the bidirectional lead screw 8, and the bidirectional lead screw 8 rotates within the sliding table 2. The slide rail 11 is used to support the bidirectional lead screw 8 and the sliding table 2, enabling the sliding table 2 and the bidirectional lead screw 8 to be lifted and lowered together when the hydraulic rod 14 drives the lifting. The rolling balls 13 are used to reduce the friction with the outer shell 1, facilitating the lifting of the slide rail 11.
[0029] Working principle: When using this device, use a lifting device to hoist the device to the position where pile pulling is required. Start the motor 3 on the upper surface of the sliding table 2. The output end of the motor 3 drives the first rotating shaft 4 to rotate. When the first rotating shaft 4 rotates, it drives the first roller 5 on the outer wall to rotate. When the first roller 5 rotates, it drives the transmission belt 6 to rotate. When the transmission belt 6 rotates, it drives the second roller 7 on the inner wall to rotate. When the second roller 7 rotates, it drives the bidirectional lead screw 8 to rotate. When the bidirectional lead screw 8 rotates, it drives the sliding blocks 9 on the outer wall to translate in opposite directions. When the sliding blocks 9 translate, they drive the clamping blocks 10 on the outer wall to translate, achieving the clamping and loosening of the pile foundation. Then start the hydraulic rod 14 inside the outer shell 1. The output end of the hydraulic rod 14 drives the sliding table 2 to be lifted and lowered. When the sliding table 2 is lifted and lowered, it drives the slide rail 11 on the inner wall to be lifted and lowered. When the slide rail 11 is lifted and lowered, it drives the sliding blocks 9 on the outer wall to be lifted and lowered. When the sliding blocks 9 are lifted and lowered, they drive the clamping blocks 10 on the outer wall to be lifted and lowered. When the clamping blocks 10 are in the clamped state, they drive the pile foundation to rise, achieving the removal of the pile foundation. For pile foundations with different shapes, rotate the turntable 16. When the turntable 16 rotates, it drives the worm 15 on the outer wall to rotate. When the worm 15 rotates, it drives the worm gear 18 on the outer wall to rotate. When the worm gear 18 rotates, it drives the second rotating shaft 19 on the inner wall to rotate. When the second rotating shaft 19 rotates, it drives the gear 20 on the outer wall to rotate. When the gear 20 rotates, it drives the rack 21 on the outer wall to be lifted and lowered. When the rack 21 is lifted and lowered, it drives the limit block 22 on the outer wall to be lifted and lowered. When the limit block 22 is fully inserted downward into the limit groove 23, the fixation of the sliding blocks 9 and the clamping blocks 10 is achieved. When the limit block 22 moves upward away from the limit groove 23, the separation of the sliding blocks 9 and the clamping blocks 10 is achieved, and the clamping blocks 10 can be replaced. Thus, not only can the effect of preventing the pile from shaking or deflecting during the pulling process and improving the stability and accuracy of the operation be achieved, but also the effect of adapting to piles with different outer shapes and increasing the adaptability and flexibility of the equipment can be achieved.
