The invention relates to the technical field of lifting appliance design, in particular to a quick unloading lifting appliance with an anti-falling structure, which comprises a lifting hook, a hinging part, a connecting part, an arc-shaped lifting hook part, a control device, an operating rod mechanism, a connecting plate, a bendable safety plate device, a first torsion spring and a second torsion spring, the control device comprises a horizontal operating rod mechanism and a horizontal connecting plate, the bendable safety plate device comprises a first torsion spring and a second torsion spring which are used for restoring to be straight, the second torsion spring is used for driving the bendable safety plate device to rotate, and the bendable handle safety plate device prevents the hanging belt from slipping off. Rotation of the bendable safety guard device and mounting and dismounting of the lifting belt are not hindered mutually, the mounting and dismounting speed of the lifting belt is increased, the bendable safety guard device is bent in one direction, the lifting belt cannot push the bendable safety guard device from the inner side of the arc-shaped lifting hook part to be bent, the operating rod mechanism is fixed in a clamped mode when goods are lifted, and the safety guard device is convenient to use. The device is suitable for suspenders of various specifications.
本发明涉及吊具设计技术领域,具体是涉及一种具有防脱结构的快速卸货吊具,包括吊钩、铰接部、连接部、弧形吊钩部、控制装置、操作杆机构、连接板、可弯折保险板装置、第一扭簧和第二扭簧,吊钩由铰接部、连接部和弧形吊钩部组成,控制装置包括有水平的操作杆机构和水平的连接板,可弯折保险板装置包括有用于恢复平直的第一扭簧,第二扭簧用于带动可弯折保险板装置旋转,可弯折把保险板装置防止吊带滑脱,可弯折保险板装置的旋转和吊带的安装和卸下不相互阻碍,提高了吊带的安装和卸下速度,可弯折保险板装置是单向弯折的,使吊带无法从弧形吊钩部内侧推动可弯折保险板装置进行弯折,在吊起货物时操作杆机构是卡接固定住的,适用于各种规格的吊带。
