Falling-preventing safety protection device

Abstract

The invention discloses a falling-preventing safety protection device. The falling-preventing safety protection device comprises a top sheave fixed to the top of hollow space in an iron tower, a lifting steel wire rope penetrating through the top sheave, a self-locking manual rope winder connected to one end of the lifting steel wire rope and fixed to the bottom of the iron tower and a rotary safety hook connected to the other end of the lifting steel wire rope, wherein a hook body of the rotary safety hook is connected to a double-insurance safety belt of operating personnel. According to the falling-preventing safety protection device, the operating personnel can be safely protected to move in the horizontal direction, and therefore reliable safety protection can be provided for the operating personnel at high altitudes.

Description

Technical field [0001] The invention relates to the technical field of machinery, in particular to a fall-proof safety protection device. Background technique [0002] The iron tower is the basic equipment in the overhead power line. In frequent operations such as the erection and maintenance of the iron tower, most of the operators use safety belts as protection. However, in the process of up and down the tower and lateral transfer, due to various reasons, such as tower height, freezing, wind and rain, operator fatigue, etc., there are situations in which safety protection fails. Sometimes, the operator may step out, miss, or go up high. Safety accidents such as falls, that is, situations where workers lose their safety protection at high altitudes often occur, and serious accidents may even cause casualties. [0003] Therefore, it is necessary to add a safety protection device to prevent falling on the iron tower to provide strong personal safety protection for the majority of o...

AI Technical Summary

Problems solved by technology

At present, most of the safety protection devices for iron tower fall protection are mainly vertical protection. For example, operators wear double safety belts and climb up to the top of the iron tower along the climbing ladder outside the iron tower. However, there is a vacuum in the safety protection of the horizontal transfer operation position, which is not ideal.
