Abstract

The invention discloses a combined type special hanger insulation tool for a safety belt. The combined type special hanger insulation tool for the safety belt comprises a hook body. A self-locking mechanism is arranged at the opening of the hook body. The self-locking mechanism comprises a barrel arranged on the hook body. The hook body is provided with a through hole, wherein a sliding rod in the barrel stretches out through the through hole. The sliding rod is connected with the bottom of the barrel through a spring. A round hole allowing a rope to penetrate through is formed in the end of the barrel. A pulley is arranged on the barrel.

Description

technical field [0001] The invention relates to a safety protection device used for maintenance of electric power equipment, in particular to a combined safety belt special hanger insulation tool. Background technique [0002] During the maintenance and construction of power transmission and transformation equipment, the operator must strictly follow the operating procedures for safety protection. When working on heights, the operator should fasten the safety belt, and at the same time connect the safety belt to the equipment structure reliably and firmly, which can To effectively prevent the operator from stepping on the air and falling, the correct use of seat belts is an important measure to prevent personal accidents. According to the needs, sometimes it is necessary to carry out the pole climbing operation without power off. The maintenance personnel often hang the safety belt on the porcelain bottle or iron frame, which may cause personal injury and equipment damage du...
