The invention provides hoisting equipment and a method for hoisting an offshore wind turbine jacket foundation, the jacket foundation comprises a transition pipe section, the hoisting equipment is used for being connected with the transition pipe section, and the hoisting equipment comprises a main body structure used for being connected with a crane and a plurality of connecting structures rotationally connected to the main body structure; the plurality of connecting structures are arranged in the circumferential direction of the main body structure; the connecting structure is provided with a rotating part and a connecting part, in the lifting process, the rotating part firstly makes contact with the inner wall of the transition pipe section, and a distance is formed between the connecting part and the inner wall; when the main body structure ascends in the axial direction, the connecting structure rotates relative to the main body structure under the friction action of the inner wall, the rotation starting part makes contact with the inner wall and rotates till the connecting part abuts against and supports the inner wall of the transition pipe section in the radial direction, and friction self-locking is formed between the connecting structure and the inner wall of the transition pipe section in the axial direction.
本发明提供了一种吊装装备和起吊海上风机导管架基础的方法,所述导管架基础包括过渡管段,所述吊装装备用于与所述过渡管段形成连接,所述吊装装备包括用于与吊机连接的主体结构,以及转动连接于所述主体结构的若干连接结构,若干所述连接结构沿所述主体结构的周向布设;所述连接结构具有起转部和连接部,在起吊的过程中,起转部首先与所述过渡管段的内壁相接触,所述连接部与所述内壁具有间距;当所述主体结构沿轴向上升时,所述连接结构在所述内壁的摩擦作用下相对所述主体结构转动,由所述起转部与所述内壁接触,转动至所述连接部沿径向抵压支撑于所述过渡管段的内壁,并在轴向上与所述过渡管段的内壁形成摩擦自锁。
