Abstract

The invention discloses a safety belt falling protector which comprises a gravity balance wheel, two clamps, a two-layer fixed splint, a bolt and a spring. The gravity balance wheel is a round plate with a center hole; two notches which are bilaterally symmetrical are formed at the upper part of the round plate; inclined chucks are arranged at the upper parts of the clamps; articulated holes are formed at the middle parts of the clamps; arc sunken ports capable of rotating around the gravity balance wheel are formed inside the middle parts of the clamps; clamping angles capable of being clamped into the notches and enabling the clamps to be opened are formed on the clamps below the arc sunken ports; support lugs are arranged at the lower ends of the clamps; the clamps are symmetrically arranged at both sides of the gravity balance wheel; the middle parts of the clamps and the gravity balance wheel are positioned in the two-layer fixed splint and are respectively and rotationally connected with the two-layer fixed splint by rotating shafts and a center shaft; the spring is positioned between the support lugs; the bolt passes through the support lugs and the spring and is fastened by a nut. According to the invention, the operation step of hanging and disassembling a safety belt aloft is simplified, both time and labor are saved in the operation process, overhaul efficiency is improved and personal safety is ensured.

Description

technical field [0001] The invention relates to the technical field of safety belts. Background technique [0002] The maintenance work on the power transmission elevated iron tower needs to climb high, and the operator must carry out effective anti-drop protection in the climbing pole tower to prevent personal accidents. In the prior art, due to the limitation of the working device conditions, it is time-consuming and laborious to connect the safety belt on the pole tower, which makes the operator of the climbing pole tower operate incorrectly, causes physical exhaustion, etc., directly threatens the personal safety of the operator, and is a must for maintenance operations. Major hidden danger. Therefore, it is necessary to take effective protective measures in the climbing operation of the power transmission elevated iron tower, so as to effectively ensure that the climbing tower operators can climb the tower quickly, conveniently and safely. The anti-fall device in the ...
