At this time, the limit platform 17 pushes the clamping blocks 11 on both sides, and slides inward at the same time with the cooperation of the fixing plate 13 and the limit rod 14, so that the rubber pad 12 contacts the pile body and clamps it. After the pile pulling is completed, the control cylinder 19 drives the limit platform 17 away from the clamping block 11. At this time, the clamping blocks 11 on both sides are driven to separate with the cooperation of the T-shaped slider 16, and the fixation of the pile body is released to complete the pile pulling process.

[0025] See also Figure 5 As shown, one end of the inner side of the screw 10 is rotatably connected to a clamping plate 24; during operation, when the pile body is fixed by the screw 10 and is prone to displacement due to uneven force, the pile body is placed between the clamping plates 24 on both sides through the structure of the clamping plates 24, and the screw 10 is rotated to push the clamping plates 24 to clamp and fix them on the pile body, thereby supporting it and preventing the pile body from being raised and tipping over.
[0026] Working principle: With the development of society and technology, old water conservancy and hydropower projects are being upgraded too much. In the process of renovation and upgrading of old water conservancy projects, the old pile body needs to be pulled out in order to install a new pile body. At this time, a pile puller is needed to perform construction operations during the construction process. When the existing pile puller performs pile pulling operations, if the mass of the pile body is large, the device is prone to tipping over due to uneven force during the pile pulling process, resulting in the pile puller being unable to be used normally. In order to solve this problem, a driving mechanism and a clamping mechanism are set to control the electric telescopic rod 22 to extend it, thereby pushing the universal wheel 23 to contact the ground and support the bottom plate 1. At this time, the device can be moved to the processing position with the cooperation of the universal wheel 23, and then the electric telescopic rod 22 is controlled to shrink to the inside of the groove 21, thereby prompting the bottom plate 1 to be placed in the ground processing position, so that the top of the pile body is inserted into the through hole 2 and the inside of the clamping block 11, and the cylinder 19 is controlled to shrink the inner piston rod 20, thereby moving the limit platform 17 toward the clamping block 11. At this time, the limit platform 17 pushes The clamping blocks 11 on both sides slide inward at the same time with the cooperation of the fixing plate 13 and the limiting rod 14, so that the rubber pad 12 contacts the pile body and clamps it, and the hydraulic cylinder 3 is controlled to extend the inner hydraulic rod 4, thereby driving the support plate 5 to contact the ground and driving the device to rise, and the pile body is pulled up. When the hydraulic rod 4 is extended to the longest, the control cylinder 19 drives the limiting platform 17 away from the clamping blocks 11. At this time, with the cooperation of the T-shaped slider 16, the clamping blocks 11 on both sides are driven to separate, and the fixation of the pile body is released. Then the control cylinder 3 is controlled to extend the inner hydraulic rod 4, thereby driving the support plate 5 to contact the ground and driving the device to rise, and the pile body is pulled up. The hydraulic cylinder 3 is controlled to move the bottom plate 1 back to the ground. At this time, the top of the pile body is located on the inner side of the limit ring 8. The screw 10 is turned to press it against the surface of the pile body, thereby playing a supporting role. Similarly, the cylinder 19 is controlled to make the clamping block 11 clamp and fix the pile body again. The hydraulic cylinder 3 is continued to be controlled to pull up the pile body. The operation is cyclical until the pile body is pulled out. After that, the fixation of the pile body is released and the pile body is taken out from the top of the limit ring 8 to complete the pile pulling process. This solves the problem of the existing pile pulling machine that the device is easy to tip over due to the offset of the center of gravity.
