Pile extractor for I-shaped pile foundation

SHAO YIQUAN

The invention relates to the technical field of pile extractors, in particular to a pile extractor for an I-shaped pile foundation. The pile extractor comprises a jaw mechanism acting on a web of the I-shaped pile foundation and used for clamping the I-shaped pile foundation, a limiting guide mechanism used for sleeving the I-shaped pile foundation and assisting the jaw mechanism in clamping the I-shaped pile foundation, a lifting mechanism is arranged below the jaw mechanism and is used for driving the jaw mechanism and the limiting and guiding mechanism to vertically lift; and a workbench, wherein the workbench is provided with a through notch, the jaw mechanism and the limiting and guiding mechanism are both arranged at the through notch, and the lifting mechanism is perpendicularly connected with the bottom side of the workbench. The pile extractor is simple in structure, good in control effect and convenient to transport and maintain, and the working efficiency can be effectively improved.
