Inertia stabilization device for crane hook

The utility model discloses an inertia stabilization device for a crane hook, and relates to the field of crane hook stabilization. The operation of an offshore crane has strict requirements on rolling and pitching angles of a ship, but a lifting hook can generate larger swing along with the movement of the ship, so that the safety of operators and construction facilities is seriously influenced, and the offshore operation efficiency and the project progress are influenced. The device comprises a damping device, a spring, a slidable inertia transmission device, a transmission connection rack and a sliding counterweight. During use, the inertia stabilization device is mounted on two sides of a side pulley box on a main hook of a crane hook, and when the hook moves, damping buffering effects of the damping device, the spring and the inertia transmission device are mutually superposed, so that energy storage, release and ablation are realized, vibration and swing of the hook can be effectively reduced, and the s
