The invention provides a lifting hook self-locking device and a lifting appliance comprising the lifting hook self-locking device, and belongs to the technical field of lifting appliances, the lifting hook self-locking device comprises a lifting base body, a lifting appliance body and a spin locking piece, the lifting base body is suitable for being fixedly connected with a workpiece to be lifted, and a lock hole is formed in the lifting base body; a containing cavity is formed in the lifting appliance body, and a shaft pin penetrating into the containing cavity is arranged on the lifting appliance body; the spin lock piece is restrained in the containing cavity, and a lock head extending out of the lifting appliance body is arranged on the spin lock piece; the lock head can stretch into the lock hole, and when the lifting appliance body and the lifting base body are in limited abutting connection, the shaft pin drives the spin lock piece to rotate along the guide of the edge line, so that the lock head rotates relative to the lock hole to form an axial constraint state of the lock head and the lifting base body. According to the lifting hook self-locking device, matched locking and unlocking of the lock head and the lock hole can be achieved through the gravity effect, it is avoided that electric equipment is used for controlling insertion and extraction of the lock head, and the lifting hook self-locking device is suitable for wider use scenes.

    本发明提供了一种吊钩自锁装置及含有其的吊具,属于吊具技术领域,吊钩自锁装置包括起吊基体、吊具本体及旋锁件,起吊基体适于与待吊工件固定连接,所述起吊基体上设有一锁孔;吊具本体内部设有容腔,所述吊具本体上设有穿设至所述容腔中的轴销;旋锁件被约束于所述容腔中,所述旋锁件上具有伸出所述吊具本体的锁头;所述锁头能够伸入所述锁孔中,并在所述吊具本体和所述起吊基体的限位抵接时,因所述轴销顺沿所述边缘线的引导带动所述旋锁件转动,以使所述锁头相对所述锁孔旋转构成二者的轴向约束状态。本发明提供的吊钩自锁装置能够利用重力效果实现锁头和锁孔的配合锁定和解锁,避免使用电动设备控制锁头插拔,有利于适配更广泛的使用场景。
