Abstract

The invention discloses a foldable and lightweight single-string output type strain insulator string device, comprising a transverse supporting rod and a longitudinal supporting rod, wherein the transverse supporting rod is fixed on the longitudinal supporting rod by a foldable mechanism to form a crawling ladder, the longitudinal supporting rod is composed of a plurality of longitudinal supporting rod units, a connecting point between each two longitudinal supporting rod units is the connecting point of the transverse supporting rod and the longitudinal supporting rod, a hanging hook is arranged at one end of the crawling ladder, and a fixing hook is arranged at the other end of the crawling ladder. The foldable and lightweight single-string output type strain insulator string device disclosed by the invention adopts a foldable structure, the space occupancy of the device is greatly reduced after being folded, therefore the device can be accommodated by one bag to be conveniently carried by a worker; a novel lightweight material is adopted to reduce the weight of the device, and thus the worker can directly carry the device on a tower for use; and the foldable and lightweight single-string output type strain insulator string device disclosed by the invention is convenient and quick to install, stable and reliable, and is high in safety. The transverse supporting rod is reinforced by a double-layer casing structure to guarantee working safety. The foldable and lightweight single-string output type strain insulator string device disclosed by the invention is simple and convenient to operate, and solves the problem that most people cannot output a single string of insulators.

Description

technical field [0001] The invention belongs to the technical field of electric power auxiliary equipment, and in particular relates to a foldable light-duty single-string tension insulator string device. Background technique [0002] Insulators are special insulation controls that can play an important role in overhead transmission lines. In the early years, insulators were mostly used on utility poles, and gradually developed into a high-voltage wire connection tower with many disc-shaped insulators hanging on one end. It is used to increase the creepage distance, usually made of glass or ceramics, and is called an insulator. Insulators should not fail due to various electromechanical stresses caused by changes in the environment and electrical load conditions, otherwise the insulator will not play a significant role and will impair the service and operating life of the entire line. When producing a single string of tension insulators, the operator can only ride on the in...

Problems solved by technology

Insulators should not fail due to various electromechanical stresses caused by changes in environmental and electrical load conditions, otherwise the insulator will not have a significant effect and will damage the service and operating life of the entire line

When producing a single string of tension insulator strings, the operator can only ride on the insulator. Due to the increased unbalanced force, the insulator string will tilt and rotate, so the operator will often drop the insulator string, which greatly increases the risk of work.

Moreover, this method of operation is more difficult, so many people cannot produce a single string of tension insulator strings.

Although some people currently use the method of climbing rope ladders to produce a single string of tension insulator strings, this method is not only labor-intensive, but also needs to carry a large number of heavy tools. Some places that vehicles cannot reach, the staff only have manual handling. Difficulty and intensity are greater, and time-consuming
