Working method of multi-stage pile pulling device with one-way locking effect

Abstract

The invention relates to the field of pile pulling, in particular to a working method of a multi-stage pile pulling device with a one-way locking effect. The multi-stage pile pulling device comprisesa manual clamping mechanism, a rotating mechanism, a lifting plate, a guide plate, a buffer treading mechanism, a buffer telescopic mechanism, an automatic clamping device, a timber pile, a jacking pipe and two one-way clamping devices. According to the working method of the multi-stage pile pulling device with the one-way locking effect, a worker is prevented from shaking the timber pile back andforth, breakage of the timber pile is avoided, the process of pile pulling through equipment is not needed, and the worker can conveniently pull the timber pile. The buffer treading mechanism drivesthe buffer telescopic mechanism and automatic clamping arms to clamp and move the timber pile upwards, the pulled timber pile is locked through the one-way clamping devices, and the timber pile is prevented from sliding downwards. The clamping range of the automatic clamping arms is large, frequent replacement of parts is avoided, the timber pile pulling process is rapid, the worker can conveniently and rapidly carry out pile pulling work, excessive labor of the worker is avoided, and the working efficiency of the worker is improved.

Description

technical field [0001] The invention relates to the field of pile pulling, in particular to a working method of a multi-stage pile pulling device with a one-way locking effect. Background technique [0002] In the process of building construction or flood fighting and emergency rescue, wooden piles are often used, and the conventional method of pulling up wooden piles is to shake the wooden piles left and right by workers, and then pull up the wooden piles, while the wooden piles are pulled up. In the process of shaking from side to side, the wood is often broken, and the wooden stake is pulled up by the worker, which requires the worker to use too much labor, causes the worker to be tired, and reduces the work efficiency of the worker. [0003] my country's patent application number: CN201810016741.7; the invention is novel in concept, ingenious in structure, strong in practicability, and can achieve the effect of pulling out wooden stakes multiple times with relatively s...

Problems solved by technology

[0007] 1. Although the third solution can clamp the top of the pile tightly, it cannot drive the pile to rotate, and the pulling up process needs to be carried out by equipment, which is not convenient for workers to pull out the pile

[0008] 2. Although both the first plan and the second plan can carry out multi-level uplifting of wooden piles, the process of installing the equipment on wooden piles is too complicated, and the process of pulling up wooden piles is too slow, which is not convenient for workers to quickly carry out Pile pulling work, and the adjustment range of the holding block on the equipment is too small, so that when encountering a wooden pile with too small diameter or a wooden pile with too large diameter, the holding block is frequently replaced, and the pulled wooden pile will have a short period of time. The decline process
