The invention relates to a method for adjusting the high-low position of a large ship main engine. The method comprises the steps that temporary supports and hydraulic jacks are installed on the periphery of a main engine base; a plurality of flat jacks are symmetrically arranged on the left and right sides of the front and rear ends below the host base according to the type size of the host and are connected with hydraulic oil pumps; four dial indicators are symmetrically mounted on the left and right sides of the upper plane of the base at the front and rear ends of the host; the host and the shaft system are centered through hydraulic jacks on the periphery of a host base and a flat jack at the bottom; the host is connected with the shaft system; detecting a crank arm opening value of a host crankshaft, a winding value of a base and a load value of a bearing; casting a main machine epoxy gasket; mounting a main machine foot bolt; the wedge-shaped gaskets are used for installing the main machine side supports and the end supports. The method for adjusting the high-low position of the main engine of the large ship is simple, convenient and easy to operate, low in cost and wide in application range, the installation efficiency of the main engine can be improved, the installation precision of the main engine can be guaranteed, and therefore the purposes of remarkably improving the quality and improving the efficiency are achieved.

    本发明涉及一种用于大型船舶主机高低位置调整的方法,包括:在主机机座四周安装临时支撑和液压千斤顶;在主机机座下方前后端左右两侧根据主机机型大小对称放置若干扁平千斤顶并连接液压油泵;在主机前后端的机座的上平面左右两侧对称安装四个百分表;通过主机机座四周的液压千斤顶和底部的扁平千斤顶将主机与轴系对中;将主机与轴系相连接;检测主机曲轴的曲柄臂开档值、机座的绕度值及检测轴承的负荷值;浇注主机环氧垫片;安装主机底脚螺栓;安装主机旁撑和端撑的锲型垫片。本发明的用于大型船舶主机高低位置调整的方法,简便易操作,成本低,适用范围广,既能提高主机的安装效率,又可保证主机的安装精度,从而起到显著提质增效的目的。
