Method for manufacturing and installing inclined curved side port

Abstract

The invention relates to a method for manufacturing and installing an inclined curved side port, which comprises the following steps: according to the practical situation of the linear curvature of the side port manufactured and installed in a hull side area, performing subsection division again to enable a new subsection to contain the whole side port, and enabling the new subsection to be named a CS24APS subsection; implementing bodiless manufacturing and integral welding on the structure of the side port and the CS24APS subsection at a time; positioning a hinge and performing preassembly on the side port; after the CS24APS subsection is assembled and unbodied, performing the preassembly on the side port in the CS24APS subsection; when docking final assembly is performed, firstly, installing a locating backer when the side port and the block of the subsection are folded; performing final fine adjustment to determine the position of the hinge by utilizing a large crane and an auxiliary assembly tool when a dock is formally provided with the side port; and then welding. The method for manufacturing and installing the inclined curved side port is capable of ensuring the operation of the dock to be safe and one-time hoisting to be successful, thereby, the production efficiency of assembly is improved, and the production cycle of the dock is shortened.

Description

technical field [0001] The invention relates to shipbuilding, in particular to a method for manufacturing and installing an inclined curved side door of a ship. technical background [0002] A purpose-built ship that requires large side doors. According to the design requirements, the center line of the side door hinge is located at the angle of 1.38 degrees between the 56# rib position of the ship and the center of the hull, and is perpendicular to the bottom line at 54 degrees from the side door to the base 8640 waterline. The outer plate line shape of the side door structure must be Consistent with the curvature of the hull. [0003] During the construction of the first ship, due to the lack of relevant reference technology, the traditional method of section division was adopted in the process of section division considering the plate specifications and section manufacturing process, and the side doors were divided into CG44PS and CS24APS sections. Between sections, the...

Problems solved by technology

[0003] During the construction of the first ship, due to the lack of relevant reference technology, the traditional division method was adopted in the process of section division considering the plate specification and section manufacturing process, and the side door was divided into CG44PS and CS24APS. Between sections, the side door can only be made as a separate structure and separately from the section. Although it is more convenient to manufacture the section and the side door separately, it is more troublesome to install in the dock in the later stage. Segmented hinges are paired, and a 700T large crane is used for installation in the dock, and there is no positioning backer, so it is difficult to get in place quickly, which brings inconvenience to the on-site construction and delays the final assembly production node of the dock
