The invention discloses a mounting method for an air guide sleeve of a full-revolving propeller of an LNG (Liquefied Natural Gas) filling ship, which specifically comprises the following steps of: S1, performing allowance processing on double-curved-surface plates, marking an allowance line on each double-curved-surface plate, and performing allowance cutting on the double-curved-surface plates according to the marking of the allowance lines; s2, forming a complete flow guide cover by the double-curved-surface plates after margin cutting, and marking three-dimensional coordinates at the connecting end points of the top edges of the curved-surface plates on the flow guide cover and the outer plate; determining a measurement coordinate system according to the center line of the ship body and the base line of the ship body, and determining three-dimensional coordinates, connected with the air guide cover, on the ship body outer plate under the measurement coordinate system through a total station; and S3, according to the three-dimensional coordinates determined on the fairing and the hull outer plate, the fairing is installed on the hull outer plate, and installation of the fairing is completed. According to the method, allowance cutting is conducted on the double-curved-surface plate, the installation position of the fairing is positioned through the total station, the installation position of the fairing is accurately controlled through the reference plane function of the total station, and finally accurate installation of the fairing is guaranteed.

    本发明公开了一种LNG加注船全回转推进器导流罩的安装方法,该方法具体包括如下步骤:S1,双曲面板余量加工,对每块双曲面板进行余量线的划制,并根据余量线的划制对双曲面板进行余量切割;S2,余量切割后的双曲面板组成完整的导流罩,标记在导流罩上的曲面板顶边与外板连接端点处的三维坐标;根据船体中心线与船体基线确定测量坐标系,并通过全站仪在测量坐标系下确定船体外板上与导流罩连接的三维坐标;S3,根据导流罩上与船体外板上确定的三维坐标,将导流罩安装在船体外板,完成导流罩的安装。本发明通过对双曲面板进行余量切割,利用全站仪定位导流罩安装位置,并通过全站仪“参考面”功能精确控制导流罩安装位置,最终保证导流罩的精确安装。
