The invention discloses a torque release device and a steel
wire rope connection structure for a crane, which relates to the technical field of
engineering machinery and is used for solving the technical problems in the prior art that a lifting hook and a raising
rope are twisted together because the torque on a steel
wire rope cannot be released. The torque release device comprises a first connecting head, a second connecting head and a
friction reducing structure, wherein an outer convex part shaped like a rotating body is fixed on the first connecting head; an inner concave part is arranged on the second connecting head; the outer convex part is embedded in the inner concave part; a first anti-loosening component is fixed on a position of the circumferential outer surface, depart from an opening of the inner concave part, of the outer convex part; a second anti-loosening component is fixed on a position of the circumferential inner surface, depart from the bottom surface of the inner concave part, of the inner concave part; the
friction reducing structure is arranged between the first anti-loosening component and the second anti-loosening component. The steel
wire rope connection structure comprises the torque release device provided by the invention, the steel wire
rope, a lifting arm and the lifting hook. As the torque release device is used, the torque on the steel wire
rope connected with the torque release device can be released effectively.
