The invention relates to the technical field of crane safety protection, and discloses a crane safety anti-falling device which comprises main fixing clamps. A movable valve is fixedly connected to the middle of the top of each main fixing clamp, a connecting rod is movably connected to the middle of the top of each movable valve, a first electric push rod is arranged on one side of the top of each main fixing clamp, one end of each first electric push rod is movably connected with a fixing plate through a pressing piece, the bottom of each fixing plate is fixedly connected with a main limiting clamp, and the top of each connecting rod is fixedly connected with a fixing column. According to the crane safety anti-falling device, through the arrangement of the main fixing clamps, auxiliary fixing clamps, main limiting clamps, auxiliary limiting clamps and spring rods, when the safe anti-falling device is used, the main fixing clamps and the auxiliary fixing clamps are fixed to one side of an object needing to be hoisted, the electric push rods push the limiting clamps to limit and fix the object, and the spring rods are further fixed according to the resilience, so that the object isprevented from shaking in the lifting and falling processes, and the safety of the device is greatly improved.

    本发明涉及起重机安全防护技术领域,且公开了一种起重机安全防落装置,包括主固定夹,所述主固定夹顶部的中部固定连接有活动阀活动连接有连接杆,所述主固定夹顶部的一侧设置有第一电动推杆,所述第一电动推杆的一端通过按压片活动连接有固定板,所述固定板的底部固定连接有主限位夹,所述连接杆的顶部固定连接有固定柱。该起重机安全防落装置,通过主固定夹、副固定夹、主限位夹、副限位夹和弹簧杆的设置,使用时,将主固定夹和副固定夹分别固定在需被吊起物体的一侧,电动推杆推动限位夹对物体进行限位固定,弹簧杆根据自身回弹性进行更进一步的固定,从而避免物体在吊起和降落的过程中晃动,大大提升了该装置的安全性。
