Technical Field

The invention relates to the field of electric power construction, in particular to an electric pole pile extractor.

Background

The rural power grid transformation involves a large amount of engineering, and a large amount of electric poles left between fields need to be dismantled. Therefore, how to effectively solve the problem that the electric pole foundation is left in the field in the process of dismantling the old pole is very important, how to prevent the old pole foundation from being left in the field to hurt people accidents, and influence the cultivation problem of common people, and the method becomes the current first work. The pole foundation is generally small in inner diameter, and the exposed end is clamped from the outside by a clamping tool in the prior art and is pulled out by being lifted upwards through various manpower or instruments. However, for the electric pole foundation with a short exposed part, soil around the foundation needs to be dug in advance, and the exposed section is prolonged, so that pile pulling can be effectively clamped, and the pile pulling efficiency is low and the labor intensity is increased.

Disclosure of Invention

The invention aims to provide an electric pole pile extractor, which aims to solve the problem that pile extraction can be carried out only by manually prolonging an exposed section for an electric pole foundation with a short exposed part in the prior art, and achieve the purposes of improving pile extraction efficiency and reducing labor consumption.

The invention is realized by the following technical scheme:

an electric pole pile extractor comprises a support, wherein a lifting mechanism is arranged on the support, a padlock assembly is hung on the lifting mechanism, and the padlock assembly is used for buckling the inner wall of an electric pole foundation; the lifting mechanism is used for driving the lock catch assembly to lift.
