Handheld tower falling protector for overhead power transmission lines

Abstract

The invention discloses a handheld tower falling protector for overhead transmission lines. The handheld tower falling protector is applied to a T-shaped tower material of an overhead power transmission line tower and comprises a fixed block, a fixed handle, a movable handle, a locking block and a rope hanging hook, a clamping groove with a U-shaped cross section is formed in the fixed block, andthe fixed handle is fixed to the side face of the fixed block. The locking block is arranged on the fixed block below the fixed handle in a rotating manner, the movable handle and the rope hanging hook are both fixed to the locking block, and a through groove capable of making the locking block extend into the clamping groove is further formed in the fixed block. When the locking block does not bear external force or is pulled downwards by the rope hanging hook, the locking block extends into the clamping groove and is used in cooperation with the side wall of the opposite clamping groove to clamp the tower material. When the movable handle and the fixed handle get close to each other, the locking block and the side wall of the clamping groove release the tower material. The handheld towerfalling protector has the advantages that the handheld tower falling protector can be directly used on the tower, a person only needs to carry one set of safety device during line patrol, and the handheld tower falling protector can be directly taken down and taken away after use, and therefore daily maintenance is also facilitated, and the jamming phenomenon is not likely to occur.

Description

technical field [0001] The invention relates to a hand-held pole tower fall arrester for overhead power transmission lines. Background technique [0002] In the operation and maintenance of overhead transmission lines, it is very important to take personal safety protection measures when the staff go up and down the tower and move on the tower. Once the safety protection is lost or the safety protection equipment fails during the climbing operation, it may lead to personal safety accidents. occur. At present, in China, for the prevention measures of overhead transmission line poles and towers falling from high altitudes, most of them adopt installation guide rail type anti-falling devices. It is mainly composed of guide rails, direction converters, anti-drop self-locking devices, safety ropes, fasteners and connecting hardware and other components. Among them, the guide rail types include C-type (groove type) and T-type (I-type), etc.; guide rails, steering gear and other ...

AI Technical Summary

Problems solved by technology

[0012] The purpose of the present invention is to provide a hand-held pole and tower anti-fall device for overhead transmission lines, which can effectively solve the problem that the guide rail type anti-fall device needs to be used in the matching guide rail, and the safety problem when the operator works up and down on the existing part of the pole tower without the guide rail installed
