The invention discloses a turnover hoisting method for a rudder horn subsection. The turnover hoisting method for the rudder horn subsection particularly comprises the following steps that a first hoisting ring, a second hoisting ring, a third hoisting ring and a transition T row are installed on the rudder horn subsection; a crane hook is fixed to the first hoisting ring and the second hoisting ring, and the rudder horn subsection is horizontally hoisted to a turnover field; after the rudder horn subsection is horizontally hoisted in place, the second hoisting ring looses the hook, and the rudder horn subsection rolls in situ by taking the third hoisting ring as a turnover fulcrum through the first hoisting ring; and the crane hook is fixed to the third hoisting ring, and the rudder hornsubsection is turned over to be in a normal state through the first hoisting ring and the third hoisting ring. According to the turnover hoisting method for the rudder horn subsection, operation is easy and convenient, the problem that in the subsection turnover process, the subsection inertially overturns due to crane overweight and subsection dead weight is effectively solved, and the subsectionhoisting safety is improved.
本发明公开了一种挂舵臂分段的翻身吊装方法,具体包括以下步骤:在挂舵臂分段上安装第一吊环、第二吊环、第三吊环和过渡T排;将吊车吊钩固定在第一吊环和第二吊环上,将挂舵臂分段平吊至翻身场地;挂舵臂分段平吊到位后,第二吊环松钩,利用第一吊环使挂舵臂分段以第三吊环为翻滚支点在原地翻滚;将吊车吊钩固定在第三吊环上,利用第一吊环和第三吊环将挂舵臂分段翻身至正态。本发明操作简单、方便,有效地解决了分段翻身过程中吊车超重、分段自重会使分段惯性倾覆的问题,提高了分段吊装的安全性。
