Anti-skid clamping mechanism based on pile foundation pulling out and operation method of anti-skid clamping mechanism

Abstract

The invention discloses an anti-skid clamping mechanism based on pile foundation pulling out and an operation method of the anti-skid clamping mechanism, and relates to the technical field of building construction. The anti-skid clamping mechanism solves the problems that existing three-shaft stirrer refitted equipment for large pile foundation pulling out construction has certain limitation, and the downward pressure is small; and for a pile foundation with a large depth, the friction force between a pile and a soil body is large, the phenomenon of insufficient lifting force exists, the construction risk is large, and the construction progress is slow. The anti-skid clamping mechanism comprises a base assembly, stable supporting leg assemblies and a rotating support body; the number of the stable supporting leg assemblies is four, and the four stable supporting leg assemblies are rotationally connected to the four corners of the base assembly correspondingly; and the rotating support body is rotationally connected to the inner side of the base assembly. The anti-skid clamping mechanism and the operation method thereof, the applicability is good, the safety is high, a sleeve can be pulled out and inserted, continuous pulling out or inserting can be achieved, the pulling out and inserting force is improved, the working efficiency and working capacity are improved, and the working adaptability and working efficiency are high.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to an anti-slip clamping mechanism based on pile foundation extraction and an operation method thereof. Background technique [0002] With the large-scale construction of urban subways, many small and medium-sized bridges in the city need to be demolished. After the bridges are demolished, the pile foundations need to be pulled out. When the pile foundations are pulled out, it is generally necessary to use a three-axis mixer to convert it into a pile pulling machine for construction. Removal of pile foundations. [0003] Based on the above, the existing three-axis mixer modified equipment for large-scale pile foundation removal construction has certain limitations. The fuselage occupies a large space and is high in height. There is a risk of large-scale equipment overturning. The casing driven by the power head is under the action of its own weight. The downward press...

Problems solved by technology

[0004] The purpose of the present invention is to provide an anti-slip clamping mechanism based on pile foundation removal and its operation method, so as to solve the limitations of the existing three-axis mixer modification equipment for large-scale pile foundation removal construction proposed in the above background technology , the fuselage occupies a large space and is high in height, and there is a risk of large-scale equipment overturning. The power head drives the casing to press down under its own weight, and the downforce is small; for pile foundations with large depths, the friction between the pile and the soil is large , there are problems of insufficient lifting force, high construction risk, and slow construction progress
