Back-up protection device for climbing power transmission line pole-tower without anti-falling protection device

Abstract

The invention relates to a back-up protection device for climbing a power transmission line pole-tower without an anti-falling protection device, and belongs to the technical field of power transmission overhaul tools. The back-up protection device for climbing the power transmission line pole-tower without the anti-falling protection device comprises a left hand protection device and a right handprotection device with left-and-right symmetrical structures, wherein the left hand protection device comprises a force bearing body clamped with the power transmission line pole-tower; a fastening piece for preventing the force bearing body from separating from the power transmission line pole-tower is arranged on the force bearing body; a through hole for hanging a safety belt mast belt or a back-up protection rope is formed in the fastening piece; and a binding piece for fixing the force bearing body onto a finger and a wrist is further arranged on the force bearing body. The back-up protection device for climbing the power transmission line pole-tower without the anti-falling protection device provided by the invention is simple in structure, safe, reliable, flexible in adjustment, stable in installation and wide in application range, and workers are ensured to climb safely.

Description

technical field [0001] The invention relates to a backup protection device for climbing a power transmission line tower without a fall protection device, and belongs to the technical field of power transmission maintenance tools. Background technique [0002] During the construction and maintenance of transmission lines, due to the installation structure of transmission line poles and towers, safety belts cannot be used to protect workers during the whole process of climbing. When climbing such poles and towers, there are potential safety hazards for personnel falling from high altitudes. Violation of Article 6.2.3 of the "State Grid Corporation Electric Power Safety Work Regulations (Line Part)": "When operators climb the pole tower, shift the position of the pole tower, and work on the pole tower, the hand-held components should be firm, and the safety protection must not be lost, and prevent The seat belt came off the top of the pole or was damaged by a sharp object."

Although this method ensures that the operators have safety protection measures in the process of climbing the pole tower, when the wire protection hook is installed and climbs up, the personnel are above the installation position of the wire protection hook, that is, the use of the safety belt is "low hanging and high use". ", violating Article 7.9 of the "State Grid Corporation of Electricity Safety Work Regulations (Line Part)": "The hook or rope of the safety belt should be hung on a strong and firm member or a steel wire rope specially used for hanging the safety belt, and should be used for high hanging. The method used”, this method also has violations
