Problems solved by technology

[0004] And the above-mentioned practice will cause a series of hull manufacturing problems, such as: the flatness requirement is not up to standard, the deck plate is damaged due to the excessive density of the code plate, or the material of the deck plate becomes brittle due to excessive welding due to excessive welding feet, etc., resulting in Causes a major rework risk of disassembly and reinstallation due to the failure of the inspection

Embodiment Construction

[0028] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0029] refer to Figure 1 ~ Figure 4 , the present embodiment provides a method for designing the profile of a hull deck surface platform, comprising the following steps:

[0030] Obtain the installation opening line of the landing grille on the deck type line plan, and take 1.5 to 2 times the diameter of the opening as the side length of the square plate, so that the center of the square plate coincides with the center of the opening circle and is located in the center of the deck centerline 1. , then the square plate intersects with the center line 1 of the deck at points A and B;

[0031] Draw the projections of points A and B on the side view of the deck mold line, c...

Abstract

The invention relates to the technical field of hull manufacturing, in particular to a design method of a hull deck surface platform molded line. By using a geometrograph, the hull deck surface platform molded line is simple, convenient and easy to make; the finished molded line is smooth in three directions; helicopter landing platform performance requirements are satisfied; a solid guarantee isprovided for smooth assembling a landing grille on a slipway; and by using method for smoothening a molded deck line in the form of a square plate in advance, a passive method of squeezing the landingplatform on site is changed; and therefore, major reworking risk caused by not passing acceptance inspection in the later period is reduced, the hull manufacturing efficiency is enhanced, and the manufacturing cost is reduced.

Description

technical field [0001] The invention relates to the technical field of ship hull manufacturing, in particular to a design method for a hull deck surface platform molding line. Background technique [0002] The smoothness of the surface of the hull deck is realized by lofting and smoothing the deck molding lines. The smoothness of the deck profile with the deck ridge arc in the longitudinal direction and the full round beam arch in the transverse direction is achieved by modifying the smoothness of the deck ridge arc, that is, by modifying the height of the deck centerline, and then obtaining a smooth deck ridge arc curve. The embedding of the helicopter landing platform on the deck surface will inevitably cause changes in the shape of the deck surface. The deck line must be modified to ensure the levelness of the landing platform on the one hand and the smoothness of the deck surface on the other hand. [0003] At present, for the embedding of the helicopter landing platfor...
