The invention provides a lifting appliance spin lock mechanism, comprising: a frame; a lock body comprising a lock head and a lock rod connected with the lock head, the lock rod being inserted in theframe, and the lock head being provided with a hanging position matched with a hung object and an avoidance position for avoiding the hung object; a locking portion arranged on the frame, and providedwith a locking position matched with the lock body to limit the lock body to rotate and an unlocking position for avoiding the lock body; and a rotary driving portion in driving connection with the lock body so as to drive the lock head to be switched between the hanging position and the avoidance position under the condition that the locking portion is located at the unlocking position. The lockbody is locked and unlocked through cooperation of the locking portion and the lock body; and after the lock body is locked by the locking portion, the lock body cannot rotate no matter whether the rotary driving portion provides power for the lock body or not, so that the situation of mistaken unlocking is effectively prevented, cargo losses and personal injuries caused by mistaken unlocking areavoided, and the production safety is guaranteed.

    本发明提供了一种吊具旋锁机构,包括:框架;锁体,锁体包括锁头及与锁头连接的锁杆,锁杆穿设在框架中,锁头具有与吊物配合的悬吊位置,及避让吊物的避让位置;锁定部,锁定部设置在框架上,锁定部具有与锁体配合,以限制锁体旋转地锁定位置,及避让锁体的解锁位置;旋转驱动部,旋转驱动部与锁体驱动连接,以在锁定部处于解锁位置的情况下,驱动锁头在悬吊位置及避让位置之间切换。通过锁定部与锁体之间的配合,实现对锁体的锁定及解锁,在锁定部将锁体锁定后,无论旋转驱动部是否给锁体动力,锁体都不会旋转,进而有效防止误解锁情况的发生,避免了误解锁造成的货物损失及人身伤害,保证了生产安全。
