Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment technology, specifically to an auxiliary equipment for power transmission tower installation. Background Technology

[0002] Power line towers are rigid support structures used in power systems to erect transmission lines. They are primarily used for high-voltage and ultra-high-voltage transmission lines, preventing corona discharge and electrostatic field hazards by ensuring the height and spacing of the conductors. Their core functions include load-bearing, conductor fixation, and safe distance control, and they must adapt to various terrain and weather conditions.

A connecting shaft passes through the middle of the take-up reel. One end of the connecting shaft extends to the outside of the fixed frame and is connected to the power end of the motor. The take-up reel is also provided with a wiring structure for connecting the transmission line.

[0004] Although it achieves the mutual connection between the fixed frame and the mounting frame, the fixed frame has a rotatable take-up wheel to tighten the transmission line, and the mounting frame fixes the fixed frame to the transmission tower, the take-up wheel in the fixed frame can be used flexibly, and the take-up wheel has a wire-passing hole, so that the transmission line can be easily fixed on the take-up wheel for tightening, thus improving the convenience of installing and adjusting the transmission line on the transmission tower.
