The invention relates to the technical field of construction safety, and discloses an anti-unhooking safety device of a crane. The anti-unhooking safety device of the crane comprises a lifting hook, wherein the bottom end of the lifting hook is fixedly connected with a fixed rail; the bottom end of the fixed rail is fixedly connected with a hook groove; one side of the hook groove is fixedly connected with a hook tip; the top end of the hook groove is movably connected with a steel wire rope; the outer side of the fixed rail is movably sleeved with a movable block; an anti-disengaging coil spring is fixedly installed on the front face of the movable block; the front face of the movable block is movably connected with an anti-disengaging rod through the anti-disengaging coil spring; the bottom end of the steel wire rope is movably connected with a lifting piston; and the bottom end of the lifting piston is fixedly connected with a magnetic block. According to the anti-unhooking safety device of the crane provided by the invention, the inner space of the lifting hook is enlarged by increasing the length of the fixed rail, so that the anti-disengaging rod can still rotate freely under the condition that multiple steel wire ropes are placed in the hook groove, and the problem that the anti-disengaging rod cannot work normally to achieve the anti-disengaging effect under the condition that too many lifting belts exist is solved.

    本发明涉及施工安全技术领域,且公开了一种起重机防脱钩保险装置,包括吊钩,所述吊钩的底端固定连接有固定轨,所述固定轨的底端固定连接有钩槽,所述钩槽的一侧固定连接有钩尖,所述钩槽的顶端活动连接有钢丝绳,所述固定轨的外侧活动套接有移动块,所述移动块的正面固定安装有防脱盘簧,且通过防脱盘簧活动连接有防脱杆,所述钢丝绳的底端活动连接有起重活塞,所述起重活塞的底端固定连接有磁块。本发明通过加长固定轨处的长度使吊钩内空间加大,保证了钩槽处在放入多根钢丝绳的情况下,防脱杆仍可自由旋动,避免了吊带过多的情况下,防脱杆不能正常工作起到防脱作用的问题。
