Problems solved by technology

[0002] In the maintenance work of workers on high-voltage transmission lines, the workers are usually bound with a safety rope for safety. When the workers accidentally fall, they can hold the workers to avoid falling directly from the line. We found in the application that this The safety rope does not have a buffer, and the safety rope will be straightened and tightened directly after the worker falls, which will easily break the safety rope and affect safety

Abstract

A portable high-voltage transmission line falling self-rescue device comprises a bottom plate, wherein a descent control device, a manual winding device and a second hook are installed on the bottom plate, a descent control rope of the descent control device is a second safety rope, the manual winding device comprises a winding device shell, and a second rotating shaft and a first rotating shaft are installed in the winding device shell. Through the combination of the descent control device and the manual winding device, when a user suddenly falls off, the second safety rope can be slowly released, so that the descent control device is preferentially used for buffering a first safety rope, and in the process that the second safety rope is slowly released through the descent control device,the first safety rope is gradually converted into a tightened state from a loosened state, so that rapid stretching of the first safety rope is avoided, and the first safety rope is prevented from being damaged easily.

Description

technical field [0001] The invention relates to a self-rescue device, more precisely a portable self-rescue device for falling high-voltage transmission lines. Background technique [0002] In the maintenance work of workers on high-voltage transmission lines, the workers are usually bound with a safety rope for safety. When the workers accidentally fall, they can hold the workers to avoid falling directly from the line. We found in the application that this The safety rope does not have a buffer, and it will straighten and tighten the safety rope directly after the worker falls, which may easily break the safety rope and affect safety. Contents of the invention [0003] The purpose of the present invention is to provide a portable high-voltage transmission line fall self-rescue device, which can be combined with a slow descender and a manual hoisting device. When the user suddenly falls, the second safety rope can be slowly released, thereby giving priority to the use of ...
