AI Technical Summary
The existing tensioning devices used in power line construction lack sufficient power, making it difficult to apply enough tension accurately and continuously, resulting in improper conductor sag and affecting the stability and safety of power transmission.
The design employs a collaborative approach involving components such as lead screws, synchronous pulleys, rollers, gears, and worm gears. The motor drives the lead screw to rotate, which in turn drives the synchronous belt and slider to slide, thereby raising the wire. The gear meshing and worm gear structure provide continuous tension, while a ring-shaped scraper removes impurities from the wire.
It achieves precise and continuous tension of the wires, ensuring that the wires are in the appropriate sag state, reducing swaying and collisions, extending the life of the conductors, improving power supply reliability and safety, and removing impurities from the wires to keep the surface clean.
