The invention relates to the technical field of hoisting construction, and provides a single-blade lightering and hoisting construction method for offshore wind turbine construction in order to solve the problem that during blade lightering hoisting, a blade tool piece is prone to generating large impact with a deck of a wind power installation ship. Comprising the following steps that S1, a plurality of limiting supports capable of vertically ascending and descending are arranged at the blade falling positions on a wind power installation ship; s2, lifting appliances of two cranes on the wind power installation ship are moved to the positions above the tool pieces at the two ends of the blade correspondingly; s3, the two crane lifting appliances are connected with the tool pieces at the two ends of the blade correspondingly; s4, the blades are hoisted to the wind power installation ship from the transport ship through cooperation of two cranes of the wind power installation ship, and the blades are located above the multiple limiting supports; s5, the limiting support is moved upwards till the limiting support abuts against the blade; and S6, when the crane lifts the blade, the limiting support is moved downwards till the tool pieces at the two ends of the blade abut against the deck of the wind power installation ship. The device has the effect of facilitating stable falling of the blades.
本申请涉及吊装施工的技术领域,针对叶片过驳吊运时,叶片工装件容易与风电安装船甲板产生较大冲击的问题,提出了一种海上风机施工单叶片过驳及吊装施工方法,包括以下步骤:S1:在风电安装船上的叶片落位处支设若干可竖向升降的限位支座;S2:将风电安装船上两处吊机的吊具分别移动至叶片两端的工装件上方;S3:将两处吊机吊具分别与叶片两端工装件相连接;S4:通过风电安装船的两处吊机配合将叶片从运输船吊运至风电安装船上,并使叶片位于若干限位支座上方;S5:通过上移限位支座直至限位支座与叶片抵接;S6:吊机吊放叶片的同时,下移限位支座,直至叶片两端的工装件抵接于风电安装船甲板。本申请具有便于叶片平稳落位的效果。
