Abstract

In recent years, snow and ice storms occur frequently in parts of southern China.

transmission lines were covered by heavy ice and a large damage was caused . In order to avoid transmission lines being crushed and ensure the normal power transmission, the heavy ice covered in high-voltage must be eliminated in time. So we propose a mechanical de-icing Vehicle in this paper through analyzing variety of pros and cons of the existing de-icing technology.

The purpose of this paper is to design an manufacture a new type of mechanical

de-icing vehicle for high-voltage lines. First we proposed a de-icing vehicle’s overall design and major problems needed to be solved, including the issue of suspension, transmission and drive, in addition to the design of ice skates, running wheels and driving wheels. Then we design and calculate the mechanical parts of the de-icing Vehicle, include the axis and ice skate’s, locking and adjusting mechanism’s design, and control parts. Then we gave the processing of axis and ice skate. In the end of the paper, we concludes innovations and show some physical and test photos.

The de-icing machinery for high-voltage proposed in this paper not only has unique

de-icing way，high de-icing efficiency，but also its the automatic adjustment of the structure can reduce the injury to high-voltage lines during the de-icing，its small size， convenient artificially carry，has wide application prospects.

Key words： De-icing machinery for high-voltage lines mechanical design control design
