The invention discloses a method for replacing a ship rudder horn, which comprises the following steps of: measuring rudder blade gap data, measuring old rudder horn data as an original record, so that a new rudder horn is measured and compared again after being installed, and a center line of a guyed rudder system is established; hoisting a new rudder horn in place, adjusting the position of the rudder horn by taking the center line of the steering engine as a reference, assembling the new rudder horn and a ship body structure together, symmetrically welding, and performing ultrasonic flaw detection and magnetic powder flaw detection on a welding seam; boring the new rudder horn by taking the center line of the guyed rudder system as a reference; and a rudderstock lower cloth and a rudder pintle cloth of the rudder horn are machined, and the steering engine, the rudder blade, the rudderstock and the rudder pintle are installed back. According to the replacement method of the ship rudder horn, the parameters of the old rudder horn are collected to serve as the positioning parameters of the new rudder horn, accurate replacement of the rudder horn can be achieved, accurate folding of the replaced new rudder horn and the ship body is facilitated, and the installation accuracy of the rudder horn can be improved by establishing the center line of the guyed rudder system.

    本发明公开了一种船舶挂舵臂的换新方法,包括以下步骤:舵叶间隙数据测量,测量旧挂舵臂数据,作为原始记录,以便新的挂舵臂安装后再次测量比对,建立拉线舵系中心线;吊装新的挂舵臂到位,以舵机中心线为基准,调整挂舵臂位置,将新挂舵臂与船体结构装配在一起,对称施焊,完工对焊缝进行超声波探伤和磁粉探伤;以拉线舵系中心线为基准,对新的挂舵臂进行镗孔;加工挂舵臂的舵杆下布司和舵销布司,将舵机,舵叶,舵杆,舵销装回。本发明一种船舶挂舵臂的换新方法通过对旧挂舵臂的参数收集,作为新挂舵臂的定位参数,可以实现对挂舵臂的精准的替换,便于更换的新挂舵臂与船体精准的合拢,建立拉线舵系中心线能够提高挂舵臂的安装精度。
