The invention discloses an oil tanker main engine base replacement method which comprises the following steps: disassembling a main engine smoke exhaust pipe and a main engine working platform, and installing a special hoisting tool for a main engine; mounting a reshipment lifting lug; a temporary supporting tool platform and a main machine upper assembly are arranged; a sliding rail is installed, a roller trolley is placed, and an old main engine base and a crankshaft are placed on the roller trolley; a process hole is formed in a position over against the old host base; the old main engine base is slid out of the cabin through the roller trolley, and then the new main engine base is moved into the cabin; the crankshaft is placed in the new main engine base, the idler wheel trolley, the sliding rail and the auxiliary hole are disassembled, and the new main engine base and the crankshaft are placed at the installation positions; transporting the host upper assembly to a new host base mounting position; and the main engine upper assembly, the main engine working platform, the crankshaft and the main engine smoke exhaust pipe are reassembled, and the main engine base is replaced. The method avoids leasing a large floating crane, avoids dismantling a large amount of reassembling projects in a living quarter, reduces cost, improves efficiency, and shortens the construction period.
本发明公开了一种油船主机机座换新方法,包括以下步骤:拆除主机排烟管与主机工作平台,安装主机专用吊装工具;安装倒运起升吊耳;设置临时支撑工装平台,主机上部总成;安装滑移轨道,放置滚轮小车,将旧主机机座与曲轴放置到滚轮小车上;正对旧主机机座位置开设工艺孔;通过滚轮小车将旧主机机座滑移出舱,再将新主机机座移进舱;将曲轴放置到新主机机座里,拆除滚轮小车、滑移轨道,回装工艺孔,将新主机机座与曲轴放到安装位置;将主机上部总成运至新主机机座安装位置;回装主机上部总成、主机工作平台、曲轴和主机排烟管,完成主机机座换新。本发明方法避免租赁大型浮吊,并且避免拆除生活区在回装的大量工程,降本增效、缩短工期。
