Anti-dropping lifting hook for steel wire rope

The utility model relates to the technical field of lifting hooks, in particular to a steel wire rope anti-falling lifting hook. Comprising a mounting frame, lifting hooks, pulley blocks and gear plates, the lifting hook is hinged to the lower part in the mounting frame; the pulley block is arranged on the mounting frame and is positioned above the lifting hook; the gear plates are arranged on the two sides of the mounting frame corresponding to the pulley blocks, and limiting grooves are formed in the inner sides of the gear plates corresponding to pulleys on the pulley blocks. In the hoisting operation, the steel wire rope is located in the groove of the pulley, the steel wire rope can be located in the groove of the pulley all the time under the action of the gear plate, and the steel wire rope is prevented from being separated from the groove. Meanwhile, a limiting groove is formed in the gear plate, the rotating end of the pulley can be located in the limiting groove, and therefore it can be guaranteed t
