AI Technical Summary

Technical Problem

The existing special lifting device for high-voltage transmission line maintenance is complicated to operate, with limited lifting height, making it difficult to adapt to the maintenance of high-voltage transmission lines with higher positions, and there are problems of unstable clamping and safety hazards.

Method used

A special lifting device for maintenance including a support plate, a first lifting mechanism and a second lifting mechanism is designed. The primary lifting adjustment is achieved through the lifting of the lifting cylinder in the communication groove in the support plate, and the sliding of the lifting column inside the lifting cylinder performs secondary height adjustment, combining the self-locking function of the worm and worm gear to ensure stability.

Benefits of technology

It realizes stable and flexible maintenance of high-voltage transmission lines, simplifies operating procedures, enhances safety, and adapts to the maintenance needs of high-voltage transmission lines at higher places.
