The invention discloses an automatic locking lifting hook of a crane. The automatic locking lifting hook comprises a hook body and a fixing box, the fixing box is fixedly connected to the upper end ofthe hook body, a sliding groove is formed in the back of the hook body, guide rollers are arranged at the bottom and the two side faces of the sliding groove, a clamping ring is arranged at the frontend of the interior of the sliding groove, the tooth surface of a soft rack faces outwards, a turbine gear is meshed with the outer side of the soft rack, a motor is fixedly connected into the fixingbox, the output end of the motor is in transmission connection with a driving gear, the outer side of the driving gear is meshed with a worm gear, the axis end of the worm gear is fixedly connected with a worm, the worm is in transmission connection with a turbine, the axis end of the turbine is fixedly connected with a transmission rod, and the turbine gear is in transmission connection with theturbine through the transmission rod. According to the automatic locking lifting hook of the crane, through the arrangement of the transmission mechanism in the fixing box, the effect of controllingthe clamping ring to be automatically clamped and blocked is achieved, the worm gear and the worm have the reverse locking effect, and therefore it is guaranteed that after the clamping ring is clamped in the clamping groove, locking can be kept all the time.

    本发明公开了起重机自动锁紧吊钩,包括钩体和固定盒,固定盒固定连接在钩体的上端,钩体的背部开设有滑槽,滑槽的底部和两个侧面均设置有导向滚轮,滑槽的内部前端设置有卡环,软齿条的齿面朝外,软齿条的外侧啮合有涡轮齿轮,固定盒的内部固定连接有电机,电机的输出端传动连接有主动齿轮,主动齿轮的外侧啮合有蜗杆齿轮,蜗杆齿轮的轴心端固定连接有蜗杆,蜗杆传动连接有涡轮,涡轮的轴心端固定连接有传动杆,涡轮齿轮通过传动杆与涡轮传动连接。该起重机自动锁紧吊钩,通过固定盒内部的传动机构的设置,起到了控制卡环自动卡接封堵的作用,蜗轮蜗杆自带逆向锁紧效果,从而保证了卡环卡接在卡槽的内部后,能够始终保持锁。
