This invention discloses a rapid mooring device and method for dock ships, comprising a base assembly, a rotating component, a sliding force transmission component, a tensioning mechanism, a tie rod assembly, and a mechanical locking assembly. The rotating component and the sliding force transmission component constitute a multi-degree-of-freedom follower mechanism to adapt to changes in the force direction of the mooring line. The tensioning mechanism drives the sliding force transmission component to achieve tensioning and release. The mechanical locking assembly includes a jump plate and a wedge block assembly for rapid coarse adjustment and precise locking of the load. Through the above structure, the small boat can achieve adaptive force adjustment during the floating and bottoming processes of the dock ship, and complete the switch of load from driven bearing to mechanical bearing on the deck. The method includes connection, tensioning, adaptive adjustment, and mechanical locking steps. This solution requires no underwater operation, has high operational safety, high mooring efficiency, and is suitable for rapid mooring and release operations of large-tonnage small boats.
