The invention discloses a large-tonnage pre-tensioning device suitable for a floating foundation anchoring system, and belongs to the technical field of wind power facility installation, the large-tonnage pre-tensioning device comprises a buoy body and at least three pre-tensioning fins, the pre-tensioning fins are uniformly distributed on the outer side face of the buoy body, one end of an anchor chain penetrates through the pre-tensioning fins, and the other end of the anchor chain is connected with an anchor. According to the anchor chain pre-tensioning device, the symmetry of a floating type foundation anchor cable can be utilized, the pre-tensioning device can be installed on a ship, preliminary pre-tensioning is completed through a 50t winch on the device, and then tension about 500t is gradually provided by a crane. By designing the proper structural strength and the chain controller, the pre-tension requirement of the required tonnage can be provided. The method can be suitable for pretensioning various symmetric floating foundation anchoring systems on the sea, the cost of a construction ship machine can be greatly reduced, the construction period is shortened, and the construction utilization efficiency of a short operation window period on the sea is improved.
本发明公开了一种适用于浮式基础锚固系统的大吨位预拉装置,属于风电设施安装技术领域,包括浮筒本体和预拉鳍,预拉鳍至少设有三个,预拉鳍均布在浮筒本体的外侧面,锚链的一端穿过预拉鳍,锚链的另一端连接锚。本锚链预拉装置,可利用浮式基础锚缆本身的对称性,在船上安装此预拉装置,并通过装置上50t绞车完成初步预拉,然后由吊机逐步提供约500t左右拉力。通过设计合适结构强度和掣链器,即可提供所需吨位的预拉力需求。可适用于海上各类对称式浮式基础锚固系统预拉,可大大降低施工船机成本,缩减施工工期,提高海上较短作业窗口期的施工利用效率。
