Problems solved by technology

[0002] At present, in the ultra-high voltage power transmission and transformation industry, there are major safety hazards in the process of using existing tools to replace the double L series insulators and double V series insulators.
The main reason is that it needs at least two workers to cooperate to replace the insulator string with the existing tools, and, because the installation position of the insulator is that one end of the insulator is close to the wire tower, and the other end is installed away from the wire tower, therefore, at least one One worker has to work at heights while completely leaving the wire tower and the whole body is suspended on the power transmission line. The safety of the operation is low, and the power transmission line is prone to breakage, resulting in accidents of high falls and casualties.
At present, there is a need for a replacement tool that can replace workers working at heights, but it is always a difficult problem to realize the automatic connection of the replacement tool with the insulator and the automatic locking of the insulator

Embodiment Construction

[0009] 1000 square millimeters of wires of the present invention are used live work big knife card replacement tool, as figure 2 As shown, it includes a housing 1, an inner chamber 2 is provided in the housing 1, four first buffer rods 3 are fixedly installed on the upper part of the inner chamber 2, and the first guide rod 66 of each first buffer rod 3 extends out of the housing. 1 travel motor 40 is installed outside, and travel sheave 4 is installed on the output shaft of travel motor 40. For convenience, the replacement insulator tool is suspended on the overhead line by the walking sheave 4, such as Figure 5 and Image 6 As shown, all the running sheaves 4 are located at the front top of the housing 1. Such as figure 2As shown, the lower part of the inner cavity 2 is symmetrically installed with two barrier-crossing brackets 28 with the central axis of the inner cavity 2 as the midline. Such as figure 2 and Image 6 Shown, each straddling obstacle bracket 28 is ...

Abstract

The invention discloses a live-line large knife clip replacement tool for a 1,000mm<2> conducting wire, which comprises a traveling mechanism. A horizontal moving mechanism is installed at the back part of the shell of the traveling mechanism. A rotating mechanism is installed on the horizontal moving seat of the horizontal moving mechanism. An adjusting mechanism is installed on the large gear of the rotating mechanism. A turnover hinge seat is installed at the front end of the rotating rod of the adjusting mechanism. The turnover hinge seat is connected with a U-shaped wire clip through a connecting plate. A limiting groove is arranged on the U-shaped wire clip. The U-shaped wire clip is hinged with a hydraulic cylinder. The piston rod of the hydraulic cylinder is fixedly connected withan insulating rod. The insulating rod is hinged with one end of a large knife clip. A positioning hook is arranged at the other end of the large knife clip. A turnover drive motor is installed on theturnover hinge seat. Two Z-shaped splints are installed on the U-shaped wire clip. The central parts of the two Z-shaped splints are hinged through a central shaft. The central shaft is fixedly connected with the U-shaped wire clip. The lower parts of the two Z-shaped splints are arranged on the two sides of the limiting groove. An electric pushrod is installed between the upper ends of the two Z-shaped splints.

Description

technical field [0001] The invention relates to a tool for changing a large knife card for live working with a wire of 1000 square millimeters. Background technique [0002] At present, in the ultra-high voltage power transmission and transformation industry, there are great potential safety hazards in the process of using existing tools to replace double L series insulators and double V series insulators. The main reason is that it needs at least two workers to cooperate to replace the insulator string with the existing tools, and, because the installation position of the insulator is that one end of the insulator is close to the wire tower, and the other end is installed away from the wire tower, therefore, at least one A staff member must leave the wire tower completely and carry out high-altitude operations under the condition that the whole body is suspended on the transmission line. The safety of the operation is low, and the transmission line is prone to breakage, ca...
