Abstract

The invention discloses an electric pole pile extractor. The electric pole pile extractor comprises a support, wherein a lifting mechanism is arranged on the support; a lock catch assembly is hung onthe lifting mechanism; the lock catch assembly is used for buckling the inner wall of an electric pole foundation; and the lifting mechanism is used for driving the lock catch assembly to ascend and descend. The electric pole pile extractor aims to solve the problem that in the prior art, for the electric pole foundation with the short exposed part, pile extraction can be carried out only by manually extending the exposed section, and the purposes of improving the pile extraction efficiency and reducing the labor consumption are achieved.

Description

technical field [0001] The invention relates to the field of electric power construction, in particular to an electric pole pile puller. Background technique [0002] The reconstruction of the rural power grid involves a large amount of engineering, and it is necessary to remove a large number of electric poles left in the fields. Therefore, it is particularly important to effectively solve the problem that the pole foundation is left in the field during the removal of the old pole. How to prevent the accident of the old pole foundation left in the field from hurting people and affecting the cultivation of ordinary people has become the current priority. The pole foundation generally has a small inner diameter. In the prior art, a clamping tool is generally used to clamp the exposed end from the outside, and it is lifted upwards and pulled out by various manpower or instruments. However, for the pole foundation with a short exposed part, it is necessary to dig out the soil ...
