Description

两条大型半漂船快速整体移位落墩方法 技术领域
本发明涉及船舶制造领域，具体为一种两条大型半漂船快速整体移位落墩方法，适用于船坞船舶建造，适用于船坞半串联建造。
技术背景
国内的大型船厂大都采用大型船坞建造船舶，一般都是半串联建造的方式，由于受到船宽方向的限制因素，常规工艺都是一条半船加上一条整船的建造模式。该模式受限于一条正穿的建造，不利于提高建造效率和资源利用。
发明内容
本发明方法涉及一种两条半船整体起浮移位落墩的方法，在船坞内两条整船同时建造完成后，对两整船后串联的两半船整体移位，有利于提高建造效率和资源利用。
本发明采用的技术方案是：一种两条大型半漂船快速整体移位落墩方法，包括以下步骤：
(1)、船坞内前部为两并齐大型集装箱船，后部为两并齐的集装箱船半船和矿砂船半船，根据压载方案进行压水，等坞门打开后，使用拖轮拉拽的方法，将两并齐大型集装箱船逐条出坞；
(2)、根据半船的搭载状态，制定压载方案，使得集装箱船半船、矿砂船半船的吃水一致，并且带有尾倾；
(3)、集装箱船半船、矿砂船半船相邻的两内侧间安装两只活络刚性梁，两只活络刚性梁首尾位置安装；
(4)、集装箱船半船、矿砂船半船相背的两外侧均安装两只移船吊耳，移船吊耳在每只半船的外侧首尾位置安装；
(5)、每只移船吊耳配备三只卸扣，三只卸扣均经钢丝绳与船坞侧的卷扬机进行连接，通过活络刚性梁，结合集装箱船半船、矿砂船半船的外侧经卷扬机经移船吊耳拉动使船舶能够前后错位整体移动再定位落墩。
集装箱船半船或矿砂船半船上经底墩座安装活络刚性梁。
活络刚性梁与船坞前后方向呈30°斜向安装。
所述移船吊耳包括主板、翼板和两侧腹板，主板垂直穿接翼板，主板的前后侧面分别设置两侧腹板，两侧腹板与主板上连通开设有三只起吊孔，三只起吊孔内分别配备三只卸扣。
该移船方法的，相比于现有技术有以下优点：
一、相对传统单整船串联半船的船坞建造方式，采用两整船建造后，整体前移两半船，有利于提高船舶建造效率，加强建造资源利用；
二、由前后两只活络刚性梁中间拉接两半船呈一整体，两半船整体移位，结合利用船坞两边的卷扬机，通过前、后设置的移船吊耳上三只起吊孔配备三只卸扣，能够对前、中、后三个方向的卷扬拉动进行微调定位，便于控制半船移位的稳定、准确，特别适用于前后方向需要错位的船舶移位。
