The invention relates to the technical field of unmanned aerial vehicles, and discloses an unmanned aerial vehicle pay-off auxiliary device, two groups of buffer column mechanisms are symmetrically mounted below a plate frame of a mounting plate frame, two groups of winding ropes are arranged on a rope winding mechanism, the rope winding mechanism is in hanging connection with the two groups of buffer column mechanisms through the two groups of winding ropes, and a lifting hook is mounted at the bottom end of a plate frame of a lifting bracket. When the paying-off auxiliary device is used for assisting the unmanned aerial vehicle in cargo lifting and transporting work, the winding rope is wound and unwound through the rope winding mechanism in an inverted hanging mode, the overall structure of the paying-off auxiliary device and a lifting hook can always keep the same gravity center, and then the overall structure of the auxiliary device and the gravity of the lifting hook are combined; the gravity stability of the winding rope is improved, the situation that the winding rope swings under the action of external wind power is avoided, and by means of double pressure reduction buffering of the buffering column mechanism, the gentle stability of cargo hoisting and placing can be improved, and impact caused by sudden hoisting is reduced.

    本发明涉及无人机技术领域,公开了一种无人机放线辅助装置,两组缓冲柱机构以对称形式安装于安装板架的板架下方,卷绳机构的卷绳数量为两组,且卷绳机构通过两组卷绳与两组缓冲柱机构挂接,吊钩安装于起吊支架的板架底端。本发明在利用放线辅助装置辅助无人机进行货物起吊运输工作时,通过利用倒挂形式的卷绳机构对卷绳的卷放,其能够使放线辅助装置整体结构与吊钩始终保持同一重心,继而利用辅助装置整体结构与吊钩的重力组合,提高卷绳的重力稳定性,避免卷绳在外界风力作用下出现风力摆动的情况,且通过利用缓冲柱机构的双重减压缓冲,能够提高货物起吊、放置的平缓稳定性,降低骤然起吊所带来的冲击。
