The invention discloses a hook device for protecting steel wire rope fracture stability of a gantry crane. The hook device comprises a machine body, wherein a working cavity is formed in the machine body, a connecting cavity located above the working cavity are formed in the machine body, and an telescopic plate capable of stretching out and drawing back is fixedly mounted on the inner wall of the bottom side of the connecting cavity; the upper end of the telescopic plate is fixedly mounted on a main beam of the gantry crane. When the device works, the upper parts of the tail ends of the telescopic plates can be locked through cooperation of main locking blocks and auxiliary locking blocks to prevent a hoisted object from falling off after a steel wire rope is broken, movement of a mounting plate can be output to enable a rope to be mounted on a lifting hook, and the lifting hook is closed through a displacement baffle; and the rope can be stabilized during hoisting through limiting of limiting blocks, so that the hoisting safety and stability are improved, the workload of workers for hanging the rope is reduced, and the hoisting efficiency is improved.

    本发明公开的一种龙门吊用钢丝绳断裂稳定保护的吊钩装置,包括机体,机体内设置有工作腔,所述机体内设置有位于所述工作腔上方的连接腔,所述连接腔底侧内壁固定安装有能够伸缩的伸缩板,所述伸缩板上端固定安装在龙门吊主梁上,该装置工作时,能够通过主锁紧块与从锁紧块配合对能够伸缩伸缩板末端上部锁紧防止钢丝绳断裂后吊装物坠落,能够输出安装板的运动使绳索安装在吊钩上,并通过位移挡板对吊钩进行关闭,能够通过限制块对绳索限制对吊装时绳索进行稳定,提高了吊装安全稳定性,减少了工人挂绳的工作量,提高了吊装效率。
