Abstract

The invention discloses an anti-falling hook for a power insulating protective umbrella, which relates to a protective tool used in live-wire operation of a power transmission line. The anti-falling hook is provided with a hook body, wherein a rotatable anti-falling clamping plate is arranged at an opening at the lower of the hook body; a guy rope is arranged on the end part of the anti-falling clamp plate; and a pulling ring is arranged on the guy rope. The anti-falling hook has the advantages: the anti-falling clamping plate is dragged by using a pull spring, and a hook mouth is clamped, so that a lead is prevented from falling from the hook mouth, and the problem of accidental unhooking is solved; and the anti-falling hook is easy to install, and is convenient to operate.

Description

technical field [0001] The invention relates to a protective tool in the live work of a power transmission line, in particular to a detachment-preventing hook under an electric insulation protective umbrella. Background technique [0002] When working on high-voltage transmission lines, when working on a multi-layer cross-arm pole tower, hanging an insulating umbrella on the upper live wire can effectively protect the safety of the staff, but the hook door of the traditional insulating umbrella hook has no safety and is easy to unhook. , not only reduces the protection of high-voltage protection tools for operators, threatening personal safety, but also causes falling objects, threatening the personal safety of ground workers. Contents of the invention [0003] Aiming at the deficiencies of the above technologies, the present invention provides an anti-detachment hook under the electric insulation protective umbrella, which prevents the wire from falling off from the hook ...
