The invention discloses an intelligent crane gripper locking piece. The intelligent crane gripper locking piece comprises a lock hole piece and a lock column piece which are welded on two sides of a gripper, a first ground plate arranged at a hoisting point of a crane and a second ground plate arranged at the hoisting end point of the crane, wherein the lock column piece consists of a ball screw power assembly; the ball screw power assembly is in electric connection with a control device; the control device is in electric connection with a grounding device. The intelligent crane gripper locking piece has the advantages that when the grounding device is in contact with the first ground plate, delayed self-locking is realized; when the grounding device is in contact with the second ground plate, delayed unlocking is realized; a threshold time within which a received signal does not act after self-locking or unlocking can be set through a digital keyboard, so that false operation can be reduced, and self-locking after loading of a hook and unlocking before stripping can be realized.
