Description

Technical Field

[0001] The invention relates to the technical field of overhead line maintenance, in particular to an overhead line maintenance and installation auxiliary tool. Background Art

[0002] At present, porcelain bottle insulators are needed for overhead lines. After long-term use, porcelain bottle insulators need to be replaced. When replacing porcelain bottle insulators, it is usually necessary to carry the overhead line on the shoulders by manpower. Such operations in high-altitude operations are not only serious safety hazards, but also consume a lot of physical strength. As a result, our work efficiency is low, which greatly delays the progress of the maintenance or installation of overhead lines, thus affecting the timely power supply of equipment. Therefore, it is necessary to add support limit devices to the overhead lines to facilitate better replacement of porcelain bottle insulators.

[0003] The authorization publication number "CN217522556U" records "an auxiliary tool for the inspection and installation of overhead lines, including a utility pole, an overhead line mounting frame is provided on the right side of the utility pole, a porcelain bottle insulator is provided above the overhead line mounting frame, a U-shaped fastener is clamped on the utility pole, and the right side of the U-shaped fastener is inserted into the lower part of the interior of the overhead line mounting frame, a nut is threadedly connected to the right side of the U-shaped fastener, and the nut is squeezed on the overhead line mounting frame, a slide groove is provided on the upper right wall of the overhead line mounting frame, and a slider is movably clamped inside the slide groove, the right wall of the slider is fixedly connected to a limit plate, and the limit plate is fitted with the overhead line mounting frame, so as to facilitate better limit support of the overhead line through the overhead line support frame. At this time, the porcelain bottle insulator can be better replaced, saving manpower, increasing work efficiency, and not prone to safety hazards."

[0004] The above patent can better support the overhead line in a limited position through the overhead line support frame. At this time, the porcelain bottle insulator can be better replaced, saving manpower, increasing work efficiency, and not prone to safety hazards. However, in reality, the device is not stable enough and is prone to shaking. Moreover, after replacement, the line will all act on the overhead line mounting frame, which is prone to tilting due to uneven force. Summary of the invention
