Manufacturing method for superstructure block of roll-on-roll passenger ship

Abstract

The invention discloses a manufacturing method for a superstructure block of a roll-on-roll passenger ship. The method includes that following steps: step S100, dividing the superstructure block intoa plurality of deck subblocks and outer plate subblocks on both left and right sides; step S200, manufacturing the deck subblocks, providing plates required for the deck subblocks, carrying out automatic marking, assembling and cutting the remaining amount on the plates on a thin plate plane subblock assembly line, to form a deck surface at one time, and installing longitudinal bones and T-shapedmaterials on the deck surface, to form the deck subblocks; step S300, manufacturing the outer plate subblocks, providing plates required for the outer plate subblocks, carrying out automatic marking,assembling and cutting the remaining amount on the plates on the thin plate plane subblock assembly line, to form the outer plates at one time, and installing longitudinal bones and T-shaped materialson the outer plates, to form the outer plate subblocks; step S400: lifting the deck subblocks in the middle from bottom to top in the assembly stage of the superstructure block, and then lifting theouter plate subblocks on the left and right sides. Each subblock of the superstructure block of the roll-on-roll passenger ship is simple to manufacture, reasonable in subblock division and short in construction period.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a method for manufacturing a topside section of a ro-ro passenger ship. Background technique [0002] A ro-ro passenger ship is a high-tech, high-value-added ship. Its main purpose is to carry passengers and vehicles. It generally has multi-deck and large-scale superstructure living quarters. In order to control the center of gravity of the empty ship and meet the stability and safety requirements of the ship, the ro-ro passenger ship generally adopts a 4-6mm thin plate structure. In order to meet the comfort and aesthetic requirements of ro-ro passenger ships, the precision requirements for thin plate construction are very high. Therefore, controlling the deformation of the thin plate of the superstructure section and improving the aesthetics of the outer plate of the superstructure section are one of the key points and difficulties in the construction of ro-ro passenger ships. ...

Problems solved by technology

[0004] At present, the division method of the superstructure section is as follows: the horizontal direction is divided into each deck as the boundary, and the vertical section is divided into left and right sections parallel to the center line of the ship, and finally divided into approximately "L"-shaped semi-stereoscopic sections. , the segment length is generally 10-12m, the segment width is 14-17m, and the segment height is about 3m (that is, the width of the outer plate is about 3m, and the length is about 10-12m). The size of the section does not match the production process and station size of the existing sheet plane segmented line, and the following problems exist: (1), the size of the de
