[0002] The hook is one of the key components of the crane, mainly used for lifting and transporting heavy objects. Its quality and performance directly affect the safety and efficiency of the lifting operation.

[0003] Currently, cranes and hooks are usually connected by a single rope. When a crane is lifting objects, since the rope is a flexible component, if the worker lifts the objects due to improper operation or bad weather (usually windy weather), the hook and the objects will swing in the air, making the operation more difficult.

[0004] Therefore, we propose a crane hook anti-deviating device to solve the above-mentioned problems. Summary of the invention

[0007] Furthermore: a first through hole adapted to the rope is opened on the side of the mounting seat, a second through hole used in conjunction with the first through hole is opened on the top of the mounting seat, and one end of the rope passes through the first through hole and the second through hole in sequence to extend to the outside of the mounting seat and connect to the crane.

[0008] Further: a first sliding wheel is rotatably mounted on the inner side wall of the mounting seat, and a rope located inside the mounting seat is slidably mounted on the first sliding wheel.

[0009] Further: a second sliding wheel located outside the mounting seat is rotatably mounted on the top of the mounting plate, and a rope located outside the mounting seat is slidably mounted on the second sliding wheel.

[0010] Further: two third sliding wheels are rotatably mounted on the outer end of the adjusting arm, and the rope passes through the gap between the two third sliding wheels.

[0011] Further: the driving assembly includes a first rotating seat fixed on the outer surface of the driving disk and a driving frame fixed on the inner end of the adjusting arm, a second rotating seat is fixed on the outer surface of the driving frame, and the same driving arm is hinged between the first rotating seat and the second rotating seat.

[0012] Furthermore: a lock buckle is fixed at the bottom end of the rope; and a plurality of lock rings used in conjunction with the lock buckle are fixed at equal intervals along the circumferential direction on the top of the hook.

[0013] Beneficial effects of the utility model:

[0014] The utility model has a plurality of adjusting arms installed on the driving box, which can support the ropes and pull the hooks through the ropes to prevent the hooks from swinging in the air due to operational reasons or weather reasons during use, thereby reducing the difficulty of operation and providing convenience to the staff; at the same time, it also prevents the goods from falling from high altitude and increasing safety hazards.

[0015] The drive box of the utility model is connected to a plurality of adjusting arms in a rotating manner, and the adjusting arms can be rotationally adjusted according to the needs of lifting, with strong flexibility; when the hook is not in use, the plurality of adjusting arms can be adjusted to a vertical state, thereby reducing the occupied space and facilitating transportation.
