Line barrier-crossing type overhead tool

Abstract

The invention relates to a line barrier-crossing type overhead tool. The tool comprises a frame. The frame comprises a crossbeam. The left end and the right end of the crossbeam are equipped with a left screwed hole and a right screwed hole respectively. Two symmetric vertical rods are welded to the bottom surface of the crossbeam. Inclined supporting rods are welded to the vertical rods and the crossbeam. The bottom ends of the two vertical rods are fixedly connected to each other via a rotating shaft. The left screwed hole is equipped with a left lift mechanism in a cooperative manner, and the right screwed hole is equipped with a right lift mechanism in a cooperative manner. A central connecting device is fixedly disposed in the middle of the crossbeam. A left pulley device is detachably disposed on the left lift mechanism, a right pulley device is detachably disposed on the right lift mechanism, and a central pulley device is detachably disposed on the central connecting device. One end of a carrying stand is arranged on the rotating shaft of the frame. One end of a foot holding stand is also arranged on the rotating shaft of the frame. The overhead tool can succeed in passing over spacers and other barriers, so workers can conduct overhead line work.

Description

technical field [0001] The invention belongs to the field of maintenance tools for high-altitude power transmission lines, and in particular relates to a line obstacle-surmounting flying car. Background technique [0002] Because the work on the ground wire of the transmission line is far away from the tower, it is difficult for personnel to reach the parts that need to be repaired, so a flying car is needed. Flying car is a means of transportation for high-altitude workers to ride on the ground wire. Its function is to transport high-altitude workers to the place that needs to be overhauled, and return after the work is completed. At present, 110KV-220KV mostly uses double-split conductors. There are facilities such as spacers, anti-vibration hammers, conductor clamps, and conductor anti-galling interphase spacers in the lines. If the above-mentioned lines need to be overhauled, there are defects in the following aspects: [0003] (1) Due to the existence of facilities suc...

AI Technical Summary

Problems solved by technology

[0003] (1) Due to the existence of facilities such as spacer rods, anti-vibration hammers, wire clamps, and wire anti-galling interphase spacer rods between the ground wires, the flying car cannot pass normally. In order to pass through the above-mentioned obstacles for the operation of the traditional flying car, it is necessary to These facilities need to be disassembled or turned over one by one, resulting in greatly prolonged operation time and labor-intensive work personnel

[0004] (2) It is also possible to use the method of overcoming obstacles for maintenance, but it is easy to fall from high altitude when overcoming obstacles, which endangers personal safety

[0005] (3) When encountering a new type of spacer, since the new type of spacer needs special tools to disassemble and assemble, it will bring difficulties to the disassembly work, and it is difficult to restore the wire anti-galling phase spacer after disassembly, which is already troublesome. Increased cumbersome operating procedures

[0006] (4) Most of the traditional unmanned line inspection robots are controlled by unmanned driving, and the staff cannot take a close observation of the line situation

[0007] At present, there are many commonly used line obstacle-crossing robots such as CN102941570B, although it also has the obstacle-crossing function and can cross obstacles on the wire, but this obstacle-crossing structure is more complicated, the operation process is inconvenient, the carrying capacity is not enough, and it is impossible to carry out manned operations. And it is inconvenient to use, so it is necessary to design a more usable line obstacle-crossing speed car to meet the needs of line maintenance
