[0022] The lifting mechanism 9 includes a connecting box 91, a first connecting plate 92, a motor 93, a first rotating shaft 94, and a first connecting member 95. One side of the second connecting block 8 is bolted to one side of the connecting box 91, and the other side of the connecting box 91 is bolted to one side of the first connecting plate 92. The top of the first connecting plate 92 is bolted to the bottom of the motor 93, and the output shaft of the motor 93 is bolted to the first rotating shaft 94. The surface of the first rotating shaft 94 is rotatably connected to the inner wall of the first connecting member 95, and the bottom of the first connecting member 95 is bolted to the top of the base plate 1. The first rotating shaft 94 transmits power through a bevel gear. A second rotating shaft 96 is movably connected, and the surface of the second rotating shaft 96 is rotatably connected to the inner wall of the connecting box 91. A first gear 97 is bolted to the surface of the second rotating shaft 96, and a rack column 98 is meshed with the surface of the first gear 97. A slider 99 is bolted to one side of the rack column 98. The connecting box has a sliding groove, and the slider 99 is slidably connected to the inner wall of the sliding groove of the connecting box 91. When the first gear 97 rotates, it drives the rack column 98 to move up and down. The sliders 99 bolted to both sides of the rack column prevent it from tilting or shifting during movement. The top of the rack column is bolted to the bottom of the protective wall 14.

[0023] Working principle: First, move the device to the work location using the casters 4, and fix it by stepping on the pedals holding the casters 4. Then, turn on the motor 93. The output shaft of the motor 93 causes the first rotating shaft 94 to rotate. Subsequently, the first rotating shaft 94 drives the second rotating shaft 96 to rotate through gear transmission. During the rotation of the second rotating shaft 96, it drives the bolted first gear 97 to rotate. Then, the rack column 98 moves upward due to the rotation of the first gear 97. During the movement of the rack column 98, the slider 99 bolted on one side allows the rack column 98 to move in the vertical direction. Then, the rack column 98 drives the upper bolted protective wall 14 to rise. The pulled-out tooth is fixed in the arc-shaped inner wall of the protective wall 14 to prevent it from tilting and tipping over after the pile is pulled out. After rising to a suitable height, turn on the cylinder 11 and the hydraulic pump 6. The output shaft of the cylinder 11 causes the push block 12 to move in the groove on the surface of the upper plate 2, causing the clamping frame 13 bolted to it to retract inward and clamp the pile. Figure 6 As shown, a partition block is provided on one side of the bottom of the push block 12, and a partition block groove is provided at a certain distance in the sliding groove. The push block 12 can not move forward further when it moves to a certain distance to prevent it from sliding out of the groove. While clamping the pile, the output shaft of the hydraulic cylinder 7 below the upper plate 2 pushes the upper plate 2 upward, so that the pile clamped by the clamping frame 13 is pulled upward. After being pulled to a certain distance, the cylinder 11 moves the clamping frame 13 back to its original position. Then the output shaft of the hydraulic cylinder 7 moves the upper plate 2 downward to its original position. Then the second round of repeated operation is started. After the pile is pulled out of the ground, the protective wall 14 restricts the pile so that it is not easy to tilt after being pulled out. Then a crane is used to bolt and move the pile out, which greatly improves the safety of the pile pulling operation and prevents casualties.
