The invention provides a half-ship assembly method based on a dock, and belongs to the technical field of ship construction. The method provided by the invention comprises the steps of mounting a first limiting mechanism at the assembly part of the first half ship structure; mounting a second limiting mechanism at the assembly part of the second half-ship structure; sequentially pulling the firsthalf-ship structure and the second half-ship structure into a dock chamber through a winch; starting guide mechanisms on a first dock wall, a second dock wall and a rear dock wall; pushing the first half-ship structure and the second half-ship structure to an assembly position; fixing the first half-ship structure and the second half-ship structure together through the first limiting mechanism andthe second limiting mechanism; firstly welding an assembly joint above a waterline; then starting an assembly device to separate the assembly part of the first half-ship structure and the second half-ship structure from water in the dock chamber; draining the water at the assembly part; and then carrying out welding, polishing and coating operations on the assembly joint to quickly finish the assembly construction of the whole ship. According to the invention, dock resources can be reasonably utilized, and the half-ship assembly efficiency is improved.

    本发明提供了一种基于船坞的半船合拢方法,属于船舶建造技术领域。本发明包括以下步骤:在第一半船结构的合拢处安装第一限位机构,第二半船结构的合拢处安装第二限位机构,通过绞车将第一半船结构和第二半船结构依次拉入坞室内,启动第一坞壁、第二坞壁和后坞壁上的导向机构,将第一半船结构和第二半船结构推动至合拢位置,通过第一限位机构和第二限位机构将第一半船结构和第二半船结构固定在一起,先焊接水线以上的合拢缝,然后启动合拢装置,将第一半船结构和第二半船结构的合拢处和坞室内的水分隔开,将合拢处的水抽干,然后对合拢缝进行焊接打磨和涂装作业,快速完成整船的合拢建造。本发明能够合理利用船坞资源,提高半船合拢的效率。
