The invention discloses a semi-submersible type hoisting and disassembling platform double-machine joint-hoisting rotation method comprising the following steps that firstly, a coordinate system of two cranes is established, wherein a crane rotation center is used as a calculation coordinate origin, a main deck surface is used as a vertical height reference point, and the leftward, upward and heading direction of the gravity center of a suspension arm rotation shaft is used as a positive direction; the anticlockwise direction is used as a positive direction of suspension arm rotation, and suspension arms right face a larboard at an angle being 0 degree; the upward direction is used as the positive direction of the pitching angle of the suspension arms, and the pitching angle of the suspension arms in a horizontal state is 0 degree; secondly, the rotation radius of auxiliary hooks of the cranes is calculated; thirdly, parameters of an initial position and a final position are determined; and fourthly, hoisting and placing are conducted. According to the semi-submersible type hoisting and disassembling platform double-machine joint-hoisting rotation method, the risk of collision is reduced, the application range of double-machine combined hoisting is widened, and the operation process is simple.
本发明公开了半潜式起重拆解平台双机联吊回转方法,包括如下步骤:(一)建立两座吊机坐标系:以吊机回转中心作为计算坐标原点,主甲板面为垂向高度基准点,吊臂回转轴所在重心向左、向上、向艏为正方向;吊臂回转以逆时针为正方向,吊臂正对左舷为0度;吊臂俯仰角度以向上为正,吊臂水平状态下俯仰角为0度;(二)计算吊机辅钩回转半径;(三)确定初始位置和终点位置参数;(四)起吊和放置。本发明减少了发生碰撞的危险,扩宽了双机联吊的适用范围,操作过程简单。
