Pre-opening method for ship outfitting

Abstract

The invention discloses a pre-opening method for ship outfitting, which comprises the following steps of: S100, establishing a structural model of a ship according to a ship design drawing; step S200,establishing a mounting hole model on the structural model according to the outfitting piece and the pipe system mounting requirement of the ship design drawing so as to determine the position, the number and the size of the mounting holes; step S300, opening holes on a plate according to the position, the number and the size of the mounting holes in the sectional manufacturing process of the ship. Through the numerical control hole opening in the early stage of ship building, the number and the workload of manual hole opening in the later stage can be reduced, the hole opening precision andthe aesthetic sense can be ensured, meanwhile, the modification of the mounting holes in the later stage can be avoided, a large number of replenishing holes of the mounting holes can be avoided, andthe structural strength of the ship body can be ensured.

Description

technical field [0001] The invention relates to the technical field of ship building, in particular to a method for pre-drilling holes for ship outfitting. Background technique [0002] In the existing ship construction process, the installation of outfitting is generally carried out when the construction is completed in sections, and the installation opening positions of each outfitting need to be confirmed on site. Using this method to create installation holes for outfitting has the following problems: [0003] 1. Determining the location of the opening at the outfitting site lacks a global perspective, and local openings need to be modified, or even repetitively supplemented, which greatly increases the workload of outfitting; [0004] 2. The structural strength of the hull cannot be guaranteed if the hole is drilled according to the location of the hole determined on site, and it is easy to damage the original structural strength of the ship, so that the structural str...

AI Technical Summary

Problems solved by technology

[0003] 1. Determining the location of the opening at the outfitting site lacks a global perspective, and local openings need to be modified, or even repetitively supplemented, which greatly increases the workload of outfitting;

[0004] 2. The structural strength of the hull cannot be guaranteed if the hole is drilled according to the location of the hole determined on site, and it is easy to damage the original structural strength of the ship, so that the structural strength of the hull decreases, and even no longer meets the design requirements of the ship;

[0005] 3. Determine the location of the hole at the outfitting site, and manually drill the hole on site, resulting in low hole precision and poor quality of the hole, increasing the difficulty of later work
