Problems solved by technology

Disadvantages: 1. The man-machine function is unreasonable
Working for a long time will cause waist soreness, leg fatigue, soreness and even cramps. 2. During the operation, the short waist rope hanging above the damaged insulator often slips to the fixture, which affects the working efficiency. 3. If the insulator string hangs down, The short waist rope will be pulled down, and the human body is connected to the cross arm through the long waist rope. The consequences of the huge impact will be unimaginable

Embodiment

[0021] Such as figure 1 As shown, the new method for safely replacing the straight tower insulators includes a full-body safety belt 1, a hanging stool 2, a short load-bearing rope 3, a buckle 4, a horn 8-shaped ring 5, a backup protection rope 6, and a main load-bearing rope 7; Described hanging stool 2 comprises support plate 8 and is arranged on support plate 8 and is positioned at the suspension ring 9 of both sides; Its concrete steps are as follows:

[0022] Step 1. Ground preparation: One end of two short load-bearing ropes 3 is respectively connected to the two earrings of the hanging stool, and then the other end is passed through the waist hoop of the full-body safety belt 1, and the two short load-bearing ropes 3 are passed through. Connect to the lower ring part of the horn 8-shaped ring 5 through the buckle 4;

[0023] Step 2. If figure 2 As shown, working at heights: personnel pass the main load-bearing rope 7 through the upper ring part of the horn 8-shaped r...

Abstract

A novel method for safely replacing a linear tower insulator comprises a whole body type safety belt, a hanging stool, a short force bearing rope, a buckle ring, ox horn 8-shaped rings, a backup protection rope and a main force bearing rope; the hanging stool comprises a supporting plate and hoisting rings arranged on the supporting plate and located on the two sides. The novel method for safely replacing the linear tower insulator has the beneficial effects that two lug rings of the hanging stool are connected through the short force bearing rope, the other end is connected with a triangularstable protrusion formed by the ox horn 8-shaped rings, and the human body balance can be kept.

Description

technical field [0001] The invention relates to the technical field of ultra-high voltage insulator maintenance, in particular to a novel method for safely replacing linear tower insulators. Background technique [0002] The current method of replacing the glass insulators of straight towers: personnel connect one end of the long waist rope to the cross arm, and the other end to the buckle behind the safety belt; after reaching the working position of the insulator string, the personnel bypass the short waist rope and hang it on the damaged insulator, and the personnel body Lean back slightly, step on the insulator string with both feet, maintain balance through the tension of the short waist rope and the support of your feet, and complete the replacement operation. Disadvantages: 1. The man-machine function is unreasonable. Working for a long time will cause waist soreness, leg fatigue, soreness and even cramps. 2. During the operation, the short waist rope hanging above t...
