The invention belongs to the technical field of shipbuilding, and discloses a positioning and mounting method for a side thrust and a side thrust sealing cover, which comprises the following steps of: S1, manufacturing a segmented jig frame, and aligning, mounting and scribing a jig frame template; s2, mounting marker posts at the first FR rib bit line and the second FR rib bit line, and drawing water lines on the marker posts; s3, determining the allowance of the side thrust cylinder, measuring the line type of the outer plate of the ship body, and carrying out simulation hoisting on the side thrust cylinder and the outer plate of the ship body; adjusting the linear deviation of the side thrust sealing cover, and carrying out allowance lineation and trimming on the upper opening of the hull outer plate according to a simulation result; s4, hoisting a side pushing cylinder body; s5, hoisting a side pushing sealing cover; s6, welding a side pushing barrel and a side pushing sealing cover; and S7, the side pushing barrel, the side pushing sealing cover and the ship body structure are welded according to the welding sequence. According to the positioning and mounting method for the side thruster and the side thruster sealing cover, a jig frame does not need to be newly added for ground pre-assembly, the side thruster device is directly and completely positioned and mounted in the segmented manufacturing stage, and the precision requirement is met.

    本发明属于船舶制造技术领域,公开了一种用于侧推和侧推封盖的定位安装方法,包括以下步骤:S1、制作分段胎架并对胎架模板对线安装,划线;S2、在第一FR肋位线处、第二FR肋位线处安装标杆,在标杆上堪划水线;S3、确定侧推筒体余量,测量船体外板线型,将侧推筒体与船体外板模拟吊装;调整侧推封盖线型偏差,根据模拟结果对船体外板上口进行余量划线及修割;S4、吊装侧推筒体;S5、吊装侧推封盖;S6、焊接侧推筒体与侧推封盖;S7、按照焊接顺序将侧推筒体、侧推封盖与船体结构进行焊接。本发明的用于侧推和侧推封盖的定位安装方法,无需新增胎架进行地面预组装,侧推装置直接在分段制作阶段完整定位安装,满足精度要求。
