Problems solved by technology

The high-voltage grounding tools currently used all need to be operated at high altitudes, which are not very convenient to use and operate, and have poor safety performance. The obvious problems of the device are: ①. Its built-in spring compression force is small, the contact resistance between the clamp and the conductor is unqualified, and it cannot protect the safety of the maintenance personnel when a sudden power comes in; ②. When the tightening force is large, it will cause the wire to break. , The wire connecting plate is loose, causing

Abstract

The invention discloses a high voltage grounding tool for power maintenance, which comprises a grounding wire chuck and an operating rod, wherein the wire chuck comprises a C-shaped hanging frame, a wire clamp moving plate and a lifting rod; a connector connected with the C-shaped hanging frame is arranged at the top of the operating rod; the upper end of the lifting rod is connected with the wire clamp moving plate; a driving mechanism connected with the lifting rod is arranged in the operating rod; the operating rod is arranged in a multi-section insertion manner; locking rings are arranged among sections of the operating rod; reducer pipes are arranged among sections of a movable casing pipe; elastic pins or key structures matched with the movable casing pipe are arranged on the reducer pipes. According to the invention, the high voltage grounding tool is hung on a wire by utilizing the C-shaped hanging frame; the wire is clamped by adopting the lifting rod; the wire-off accident is prevented; the low-position safe operation is realized; the potential safety hazard caused by the climbing operation is avoided; the working difficulty is reduced; the working efficiency is improved; the sectional design concept is adopted; the flexible variation of the length of the operating rod is ensured; in the transmission link, the interchangeable connection can be carried out; the effects are obvious.

Description

technical field [0001] The invention belongs to the technical field of safety tools, in particular to a high-voltage grounding tool for electric power maintenance. Background technique [0002] The high-voltage grounding tool is one of the safety tools commonly used in the maintenance of high-voltage lines. It is used to temporarily connect the power supply to the ground to prevent the power line from being powered off due to misoperation and other reasons. The high-voltage grounding tools currently used all need to be operated at high altitudes, which are not very convenient to use and operate, and have poor safety performance. The obvious problems of the device are: ①. Its built-in spring compression force is small, the contact resistance between the clamp and the conductor is unqualified, and it cannot protect the safety of the maintenance personnel when a sudden power comes in; ②. When the tightening force is large, it will cause the wire to break. 1. The wire connectin...
