The invention discloses a double-vehicle combined hoisting method for a stern block of an ultra-large container ship and an auxiliary tool thereof, and relates to the technical field of ship manufacturing. The extension platform tools are installed on the stern block, the problem that when a gantry crane is used for completing segmented hoisting, a lifting hook cannot completely cover segments is solved, the problem that the 3-degree angle of a steel wire rope is out of tolerance is solved, and the weight of the lifting hook is prevented from being out of tolerance through the balance weight tool. The extension platform tool can be repeatedly used, tool material loss is reduced, the mounting and dismounting process is convenient and fast, and an original hull structure does not need to be changed. According to the method, the in-dock operation of a plurality of subsections of the stern block of the ultra-large container ship is moved forwards before in-dock closure, the construction operation of the block is completed in the ground total assembly stage, after the stern block is constructed, the stern block is hoisted into the dock by adopting a double-vehicle combined hoisting method, the in-dock operation of the plurality of subsections is changed into the in-dock block operation, and the construction efficiency is improved. The operation time in the dock is effectively shortened, the utilization rate of the dock is improved, and the production progress is accelerated.

    一种超大型集装箱船艉部总段的双车联吊方法及其辅助工装,涉及船舶制造技术领域。本发明在艉部总段上分别安装延伸平台工装,解决了使用龙门吊来完成分段吊运时吊钩无法完全覆盖分段的问题,避免了钢丝绳3°角的超差问题,使用配重工装避免了吊钩重量超差。延伸平台工装可,重复使用,减少工装材料损耗,安装及拆卸过程方便快捷,无需改变原有船体结构。本发明将超大型集装箱船艉部总段的若干的分段坞内作业前移在坞内合拢前,在地面总组阶段完成总段的施工作业,艉部总段建造完成后,采用双车联吊方法将艉部总段吊装至坞内,将若干的分段坞内作业改为了坞内总段作业,有效缩短船坞内的作业时间,提高船坞利用率,加快了生产进度。
