ZHANG SHUGUANG / QIAN YUGUANG / GAO HONGHU / GONG BING / GAO ZHIJIAN

The invention discloses a lifting pile leg for a wind power installation vessel, which comprises a plurality of pile leg units, and the pile leg units can be stacked up and down and detachably mounted into an integral pile leg structure; each pile leg unit correspondingly comprises three chord members which are vertically arranged, and vertical racks used for mounting lifting mechanisms are correspondingly arranged on the two sides of each chord member; horizontal connecting pipes are correspondingly mounted between the adjacent chord members in the pile leg units, and a triangular area is formed in the pile leg through the arranged horizontal connecting pipes. The horizontal connecting pipes are installed at the upper ends and the lower ends of the three chord members of a single pile leg unit, then the inclined supporting pipes are correspondingly installed on the three vertical planes, in this way, the three chord members are installed into a whole from the upper end, the lower end and the side face, and each chord member is provided with the vertical rack used for installing the lifting mechanism. When the upper and lower pile leg units are installed in a butt joint mode, the upper and lower vertical racks correspond in position, installation of the lifting mechanism can be achieved, and the lifting mechanism is used for a wind power installation ship.

本发明公开一种用于风电安装船的提升桩腿，包括若干个桩腿单元，桩腿单元可上下叠放可拆卸安装成整体式桩腿结构；每一桩腿单元均相应包括三根竖向布置的弦杆，且每一弦杆的两侧均相应设置有用于安装提升机构的竖向齿条；且所述的桩腿单元中相邻的弦杆之间还对应安装有水平连接管，通过设置的水平连接管在桩腿的内部构成三角形区域。本发明单个桩腿单元的三个弦杆在上下端均安装有水平连接管，然后在三个竖向平面上又对应安装有斜向支撑管，这样设置后从上下端以及侧面将三个弦杆安装成一整体，且每一弦杆上都设置有用于安装提升机构的竖向齿条，上下的桩腿单元对接安装时，上下的竖向齿条位置对应，可实现提升机构的安装，用于风电安装船。
