The invention discloses a preassembling method for a double-rudder type segmented rudder horn. The preassembling method comprises the following steps of assembling a stern part segment in an inverted state; drawing a theoretical center point of a rudder hole of the rudder horn section on the ground according to the section center line and the rib detection line of the stern section; determining the machining allowance on the rudder horn sections , and performing allowance cutting; reversely hoisting the two rudder horn sections to the corresponding rudder horn preassembling positions on the stern section; structurally reinforcing the lower end faces of the two rudder horn sections by the reinforcing inclined struts, and synchronously welding and fixing the two rudder horn sections. By the reasonable design of the segmented inverse-state total assembly support, the allowance of the rudder horn is cut off in advance for preassembly, and the installation precision and the installation efficiency of the rudder horn are effectively guaranteed.

    本发明公开了一种双舵型分段挂舵臂预装方法,包括以下步骤:反态总组艉部分段;根据艉部分段的分段中心线和肋检线在地面上画出挂舵臂分段舵孔的理论中心点;确定挂舵臂分段上的加工余量并进行余量切割;将两个挂舵臂分段分别反态吊放到艉部分段上对应的挂舵臂预装位置;利用加强斜撑对两个挂舵臂分段的下端面进行结构加强,然后对两个挂舵臂分段同步进行焊接固定。本发明通过分段反态总组支撑的合理设计,提前割除挂舵臂的余量进行预装,有效地保证了挂舵臂的安装精度和安装效率。
