Abstract
Description
Technical Field
[0001] This utility model relates to the field of overhead power line technology, specifically to a tool for erecting overhead power line conductors. Background Technology
[0002] Overhead lines mainly refer to exposed overhead lines, erected above the ground. They are power transmission lines that use insulators to fix the transmission conductors to towers standing upright on the ground to transmit electrical energy. They are relatively easy to erect and maintain, and have lower costs. However, they are easily affected by weather and environmental factors (such as strong winds, lightning strikes, pollution, ice, and snow), which can cause faults. At the same time, the entire transmission corridor occupies a large area of land and is prone to causing electromagnetic interference to the surrounding environment. The main components of overhead lines include: conductors and lightning protection wires (overhead ground wires), towers, insulators, hardware, tower foundations, guy wires, and grounding devices.
[0003] Currently, the traditional construction method for overhead line conductor erection is to first erect the conductor manually and then tighten it. Both conductor laying and tightening are high-altitude operations, which make it difficult for personnel to move on the tower and are easily affected by rain and wind. This results in slow construction efficiency, difficulty in controlling construction quality, and a high risk of safety accidents such as falls from heights and being struck by objects from above.
[0004] To further improve the speed and quality of overhead line conductor erection and reduce the time spent by construction workers at height, our unit has summarized the conductor erection process using a winch and traction rope, based on the construction of the Guoneng Qingyu 900MW photovoltaic overhead line conductor. This method can reduce the conductor erection time, reduce the time workers spend at height, and improve construction efficiency, thus having certain advantages. Summary of the Invention

A reduction motor connected to the support plate is provided at one end of the drive shaft. A transmission gear meshing with a gear ring is sleeved on the outside of the drive shaft. Two guide wheel sets are arranged parallel to the end of the support plate near the grounding trolley.

[0017] This utility model provides a tool for erecting overhead power line conductors, which has the following advantages:

The wire laying is carried out by suspending a wire laying pulley on the overhead iron tower and using a traction rope and winch. The process is simple and easy to operate, and it is suitable for the construction of lines below 35kV.
