The invention relates to an installation method of a ship front prerotation guide wheel, the prerotation guide wheel comprises a guide pipe and a plurality of guide vanes, the guide vanes are installed on a ship body tail ball casting in a divergent mode, and the guide pipe is of an arc-shaped structure and is connected to the other end of each guide vane; the method is characterized by comprising the following steps: S1, establishing a coordinate system; s2, guide wheel movement; s3, guide wheel positioning monitoring; s4, preparation before welding of the guide wheel; s5, welding the guide wheel; five sample punching marks are arranged on a guide pipe, and coordinates of all sample punching marks are tracked and monitored in real time; in the final guide wheel welding process, the subsequent welding procedure is well controlled, and the theoretical coordinates of various sample punching marks are met after final mounting and forming; the problem that the guide wheel is difficult to position in the installation process is solved, the installation precision of the guide wheel and the guide vane is improved, and therefore the navigational speed of a ship can meet the requirement.

    本发明涉及一种船舶前置预旋导轮的安装方法,预旋导轮包括导管和导叶,导叶具有若干且呈发散状安装在船体尾球铸件上,导管呈弧形状结构连接在各导叶的另一端上;其特征在于:具体安装方法如下:S1:建立坐标系;S2:导轮移动;S3:导轮定位监测;S4:导轮焊接前准备;S5:导轮的焊接;通过在导管上设置五处样冲标记,并进行实时跟踪监测各样冲标记处的坐标;在最终的导轮焊接中,控制好后续的焊接工序,在最终的安装成型后满足各样冲标记的理论坐标;解决了导轮安装过程中难定位的问题,提高导轮以及导叶的安装精度,从而使得船的航速能够达到要求。
