Problems solved by technology

[0006] In order to overcome the problem of replacing insulators in the seaside area in the prior art, when the insulators are lifted, because the moisture content in the air is high, if the insulators are not protected to a certain extent, a large amount of water will often accumulate on the surface of the insulators after they reach the installation height. The water vapor on the surface of the insulator will increase the conductivity of the insulator surface, which will become a risk factor for the replacement of the insulator. At the same time, some insulators are long and inconvenient to clean. The stains on the surface of the insulator will increase the probability of pollution flashover; In sudden windy weather, when replacing insulators, it is necessary to replace and fix the wires fixed on the old insulators to the new insulators. After the wires are removed from the old insulators, the unbound wires will swing irregularly due to the sudden strong wind. The swinging wire cannot be captured and fixed again, and it is inconvenient to disassemble and install the insulator. The technical problem to be solved by the present invention is to provide an auxiliary lifting device for insulator strings in power engineering maintenance.

Abstract

The invention relates to auxiliary lifting equipment for an insulator string in electric power engineering maintenance. The invention aims to solve the technical problems that an insulator is lifted and installed in an auxiliary manner, a high-voltage line shakes under the influence of wind power, and the probability of pollution flashover of the insulator is reduced. In order to solve the technical problem, the invention provides the auxiliary lifting equipment for the insulator string in the electric power engineering maintenance, which comprises a scissor-type lifter, a lifting operation table, an opening and closing control system, a line capturing system, a cleaning system and the like, and a lifting operation table is mounted at the top of the scissor-type lifter. According to the invention, the automatic lifting of the insulator is realized, the outer surface and the inner side of the insulator are cleaned in the lifting process, the possibility of pollution flashover of the insulator in the installation and use process is reduced, and the effects of automatically capturing and positioning a wire which swings severely due to strong sea wind on the sea and facilitating the installation of the insulator can be achieved.

Description

technical field [0001] The invention relates to the field of electric power engineering, in particular to an auxiliary lifting device for insulator string maintenance in electric power engineering. Background technique [0002] At present, in the prior art, insulators are replaced in seashore areas. When lifting insulators, because the air has a high moisture content, if the insulators are not protected to a certain extent, a large amount of water vapor will often accumulate on the surface of the insulators after they reach the installation height. , which leads to the enhancement of the conductivity of the insulator surface, which becomes a risk factor for the replacement of insulators. At the same time, some insulators are long and inconvenient to clean. The stains on the surface of the insulator will increase the probability of pollution flashover; [0003] Moreover, there are often sudden strong winds in the coastal area. When replacing the insulator, it is necessary to ...
