Embodiment Construction

[0029] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0030] Taking the stern thruster of S1049 liquefied gas ship as an example, the splicing work of the platform plate needs to be completed before the installation of the stern thruster equipment, the platform plate needs to be leveled, and the allowable tolerance is ±2mm. The platform plate is hoisted to this section for positioning. In order to ensure that the hull platform plate meets the installation requirements of 5° fore and stern deviation and 3° left and right deviation for equipment installation, it is necessary to position the hull platform plate along the width and length of the ship by pulling steel wires. ,Such as Figure 1-2 As shown, the specific positioning data is as follows:

[0031] Along the width of the ship: midship anchor point: X=FR0, Y=±2500,

[0032] Z= 6092 (from baseline), 1908 (from main deck, excluding plate thickness);

Abstract

The invention discloses a ship stern thrust equipment positioning and assembling and welding method, and relates to the technical field of ship manufacturing, the ship stern thrust equipment positioning and assembling and welding method comprises the following steps: manufacturing and installing a prosthesis, positioning a stay wire of a prosthesis structure, adjusting and cutting a ship body rib plate according to the fitting condition of the prosthesis and the ship body rib plate, then installing stern thrust equipment, and adjusting the fitting condition of an equipment rib plate and the ship body rib plate. The wire pulling is convenient, and the positioning is convenient. The stern thrust equipment is easy to install, the prosthesis can be repeatedly used, and the stern thrust equipment is suitable for quantitative production.

Description

technical field [0001] The invention relates to the technical field of ship manufacturing, in particular to a positioning and welding method for ship stern thruster equipment. Background technique [0002] Ship stern propulsion equipment mainly includes propellers, adjustable propellers, jet thrusters, etc., which are the source of power for ships. When manufacturing a ship, in order to ensure that the hull platform plate meets the installation requirements of the equipment, the general hull will be slightly inclined, and the installation plane of the stern thruster equipment is an inclined plane. When installing the stern thruster equipment, the position of the hull rib and the position of the equipment rib should be adjusted at the same time. It is inconvenient to pull the wire, resulting in difficult and inaccurate positioning of the equipment. Contents of the invention [0003] In view of the above problems, the present invention provides a positioning and welding met...
