The invention relates to the technical field of aircraft ground service guarantee, in particular to an aircraft emergency traction device which comprises an adjusting mechanism used for aircraft emergency traction supporting, a pushing mechanism used for jacking up aircraft front wheels is arranged on the adjusting mechanism, and the aircraft emergency traction device further comprises a clamping mechanism used for rapidly clamping and fixing the aircraft front wheels. The four steel wire ropes are wound through rotation of the rotating frame, then the clamping rods are pulled to slide along the grooves of the overturning arms through winding of the four steel wire ropes, so that the four clamping rods rapidly clamp and loosen the front wheel of the airplane, and then the fixing speed of the front wheel of the whole airplane is increased; the worm gear and the rotating frame are driven to rotate through rotation of the worm, locking of the rotating frame is achieved through the self-locking characteristic of the worm gear and the worm, and therefore reverse sliding of the clamping rod is prevented, and locking and clamping of the whole front wheel of the airplane are guaranteed.

    本发明涉及飞机地面勤务保障技术领域,特别是涉及一种飞机应急牵引装置,包括用于飞机应急牵引支撑的调节机构,调节机构上设置有用于对飞机前轮进行顶起的顶推机构,还包括用于对飞机前轮进行快速夹持固定的夹持机构。通过旋转架的转动来让四个钢丝绳进行缠绕,随即通过四个钢丝绳的缠绕来拉动夹持杆沿着翻转臂的凹槽滑动从而使四个夹持杆对飞机前轮进行快速加持和快速松开,继而提高整个飞机前轮的固定速度,利用蜗杆的转动来带动蜗轮和旋转架进行转动,利用蜗轮蜗杆的自锁特性实现对旋转架的锁定,从而防止夹持杆反向滑动,继而保证整个飞机前轮的锁定夹持。
