500 kV transmission line pole tower bird's nest removal special clamp

Abstract

A clamp dedicated for removing bird nests on 500 KV transmission line towers comprises two handles, the two handles are hinged to each other in the middle, a main rod is installed at the end part of each handle, three capture hooks are installed at the end part of each main rod, each capture hooks comprises a sub rod, one end of the sub rod is equipped with a first bent hook, and the end part of the first bent hook is equipped with a second bent hook. According to the clamp provided by the invention, each main rod is provided with three capture hooks, so the matching area of the capture hooks and a bird nest is raised, falling of twigs of the bird nest in a capturing process is avoided, and thus the cleaning efficiency of the bird nests is raised. A foldable structure is disposed between each main rod and the corresponding handle, and an inserting block can enter into a space formed by a first matching groove and a second matching groove after the main rod and the handle are folded, thus to realize locking of the main rod and the handle, thereby reducing the overall length of the clamp and bringing convenience for receiving.

Description

technical field [0001] The invention relates to a special clamp, in particular to a special clamp for dismantling a bird's nest of a 500-kilovolt power transmission line tower. Background technique [0002] The 500kV transmission line bird's nest removal special clamp is similar to ordinary clamps, including four parts: grabbing hook, clamp body and handle. Existing special tongs for bird's nest removal only have a single grapple, and in the process of grabbing the bird's nest, it is easy to drop branches, and simultaneously cannot quickly grab a large amount of branch materials for building the bird's nest. Existing special clamps for bird's nest removal are relatively long and cannot be conveniently accommodated. Contents of the invention [0003] The object of the present invention is to provide a special clamp for removing the bird's nest of a 500 kV power transmission line tower, which can solve the above problems. [0004] In order to achieve the above object, the ...
