Falling-preventing safety belt for hot-line work

Abstract

A falling-preventing safety belt for the hot-line work is formed by shoulder belts, a chest belt, back belts and a waist belt in a sewn mode. The two shoulder belts are arranged, one end of one shoulder belt and one end of the other shoulder belt downwards extend from the front portions of the left shoulder and the right shoulder of a wearer correspondingly, the other end of one shoulder belt andthe other end of the other shoulder belt downwards extend from the rear portions of the left shoulder and the right shoulder of the wearer correspondingly, and the shoulder belts are fixedly connectedon the back portion through a fixing part. The chest belt is set to be a part with the adjustable length and is transversely arranged at the chest position, and the two ends of the chest belt are movably connected with the two shoulder belts through first connecting parts. The two back belts are arranged, one end of each back belt is connected with the fixing part, and the other end of one back belt and the other end of the other back belt downwards extend from the two sides of the back of the wearer correspondingly. The waist belt is transversely arranged at the waist position, and the two ends of the waist belt are connected with the two back belts correspondingly. The shoulder belts and the back belts are connected with each other on the legs of the wearer through second connecting parts and used for being matched with the legs of the wearer and being worn on the legs of the wearer. The shoulder belts, the chest belt, the back belts and the waist belt are made of textile strips, and the textile strips are made of mulberry silk fibers and chemical fiber filament fibers in a mixed and woven mode.

Description

technical field [0001] The application belongs to the technical field of protective equipment for safe operation, in particular to an anti-fall safety belt for live work. Background technique [0002] Power distribution live work refers to a method of maintenance and testing on high-voltage electrical equipment without power failure. Electrical equipment needs frequent testing, inspection and maintenance during long-term operation. Live work is an effective measure to avoid maintenance blackouts and ensure normal power supply. The content of live work can be divided into several aspects such as live test, live inspection and live maintenance. The objects of live work include electrical equipment in power plants and substations, overhead transmission lines, distribution lines and distribution equipment. The main items of live work include: live replacement of line tower insulators, cleaning and replacement of insulators, washing insulators with water, crimping and repairin...

AI Technical Summary

Problems solved by technology

[0004] Most of the existing anti-fall safety belts are made of polypropylene fiber, polyester fiber or nylon fiber. The safety belt made of this kind of material will break down and break when the high voltage is 170KV, which cannot meet the live work under the high voltage environment of 220KV; moreover, the storage It is easy to get damp in the environment, and when the relative humidity is greater than 85%, it cannot be used normally in the power distribution and live work. It must be stored in a dry environment. If it gets wet during transportation and use, it will cause it to fail to work. It must be dehumidified. It can be used after drying; if there is a sudden thunderstorm in the process of power distribution liveliness operation, the ordinary fall protection seat belt cannot be removed safely in time, which will cause great harm to the construction workers and directly threaten the personal safety of the workers. It is a problem that has plagued the power distribution live power industry for a long time
