AI Technical Summary

Technical Problem

Existing poleless aircraft tractors are cumbersome to operate when clamping and lifting the front wheel of the aircraft, and are difficult to adapt to aircraft of different sizes and specifications, which easily damage the spindle of the front wheel of the aircraft.

Method used

An unmanned intelligent rodless aircraft tractor is designed, adopting a combined structure of semi-slip ring and clamping assembly. The clamping block and clamping assembly are driven by the telescopic shaft of the hydraulic cylinder to achieve accurate clamping and lifting of the front wheel of the aircraft, and the adaptability and safety of aircraft of different specifications are ensured by rotating the arc stop plate and brake ring.

Benefits of technology

It realizes efficient clamping and lifting of the front wheel of the aircraft, adapts to aircraft of different specifications, avoids damage to the front wheel spindle of the aircraft, and ensures the safety of the aircraft during the steering process.
