The invention discloses a clamping-lifting device for an aircraft tractor. The device comprises a clamping mechanism and a lifting mechanism. The lifting mechanism adopts a lifting motor to drive a steel rope reel, and the nose landing gear of the aircraft can normally ascend and descend through a plurality of pulleys. During turning, the rotary motor drives the pin tooth rotary disc driving wheel, so that the pin tooth rotary disc drives the nose landing gear of the aircraft to rotate. The clamping mechanism adopts a slider-crank mechanism, an undercarriage clamping connecting rod is connected with an aircraft nose undercarriage through a clamping rod pin shaft during clamping and fixing, a hydraulic device and a wheel holding mechanism which are commonly used in an existing device are not adopted, the problems of maintenance of the hydraulic device, oil leakage and the like do not exist, and the device is clean, environment-friendly, low in production and maintenance cost, simple and novel in structure, high in working efficiency and suitable for popularization and application. And moreover, the clamp can be matched and fixed with nose landing gear shafts of aircrafts with different heights, is high in universality and is particularly suitable for clamping and fixing old aircrafts.

    本发明公开了一种用于飞机牵引车的夹持‑举升装置。其包括夹持机构和举升机构。举升机构采用举升电机驱动钢绳卷轴,通过多个滑轮使得飞机前起落架正常升降。转弯时,回转电机驱动销齿回转盘驱动轮,使销齿回转盘带动飞机前起落架转动。夹持机构采用曲柄滑块机构,夹持固定时,起落架夹持连杆与飞机前起落架通过夹持杆销轴连接,未采用现有装置常用的液压装置和抱轮机构,不存在液压装置的维护及油液泄露等问题,清洁环保、生产维护成本低、结构简单新颖、工作效率高,并且可与不同高度的飞机前起落架轴配合固定,通用性高,特别适用于老式飞机的夹持固定。
