The invention discloses a hoisting unhooking prevention device, and belongs to the technical field of hoisting equipment. The hoisting unhooking prevention device comprises a hoisting shackle, a shackle column, a shackle locking assembly, a limiting pull rod and a shackle limiting assembly. The shackle locking assembly comprises a supporting ring, a locking ring and a shift ring, wherein the supporting ring is arranged in a ring, the locking ring is arranged in a ring, the locking ring and the supporting ring are arranged in a concentric circle, the shackle limiting assembly comprises a limiting sleeve box, a self-adaptive limiting block and a hinged shaft, and a friction limiting layer is arranged on the side, close to the shackle column, of the self-adaptive limiting block. The hoistingequipment particularly relates to the hoisting unhooking prevention device that can precisely adjust the tightness of the locking assembly, can limit a hoisting rope into the hoisting shackle withoutunhooking, can enable different types of hoisting shackles and shackle heads of the limiting hoisting shackle to be matched through the self-adaptive function of the shackle limiting assembly, plays arole of sealing the hoisting shackle, and further prevents unhooking.

    本发明公开了一种吊装防脱钩装置,包括吊装钩环、钩环柱、钩环锁紧组件、限位拉杆和钩环限位组件,所述钩环锁紧组件包括支撑环、锁紧环和移位环,所述支撑环呈环状设置,所述锁紧环呈环状设置,所述锁紧环与支撑环呈同心圆设置,所述钩环限位组件包括限位套盒、自适应限位块和铰接轴,所述自适应限位块靠近钩环柱的一侧设有摩擦限位层。本发明属于吊装设备技术领域;具体是指一种可以精准调节锁紧组件的松紧度,实现限制吊绳限制在吊装钩环内而不会脱钩,通过钩环限位组件的自适应的功能实现匹配不同型号的吊装钩环和限位吊装钩环的钩头,起到封闭吊装钩环的作用,进一步防止脱钩的吊装防脱钩装置。
