Abstract

1. A method of manufacturing a ship hull, comprising the steps of forming a hull of the hull blocks in the beds and fixing it on their fixed patterns, mounting the kit and equipment on each of the hull blocks, detaching it from the fixed bed patterns, testing for water resistance, preparatory work for docking each of the blocks with adjacent blocks of the ship's hull, transporting these blocks to the place of their assembly and connecting with each other, characterized in that, in order to reduce labor intensity and increase the accuracy of At the same time, removable bed templates are fixed on the casing of the block at the same time as the fixed patterns, which are detached after the assembly of the block with adjacent blocks is completed. 2. A device for manufacturing a ship hull comprising a bed with a base and fixed patterns, characterized in that the device is provided with a removable frame with patterns mounted on the bed base, which are placed between the fixed patterns on one side of the working pattern of the bed regarding the bed base. i СЛ 16 1C Ю СО Fig, .1

Description

The invention relates to shipbuilding, in particular to the manufacture of small and medium-sized vessels, and concerns the technology of making zonal blocks, the design of which has a small perishing and rigidity, for example, zonal blocks on the deck and side sections.

The purpose of the invention is to reduce the labor intensity and increase the accuracy of manufacturing.

FIG. 1 shows an apparatus for carrying out a method for manufacturing a ship hull; in fig. 2 - the same plan view; in fig. 3 is a section A-A in FIG. 2; in fig. 4 is a section BB in FIG. 2; in fig. 5 - hinge device; in fig. 6 is a view of B in FIG. five.

A device for carrying out the method of manufacturing a ship hull consists of a combined bed made in the form of bed 1 and a removable part of bed 2. The removable part of bed 2 consists of a welded frame 3 in which patterns 4 are fixed with constant pitch, the upper edges of which are curved the outer surface of the section, for example the deck. In order to stiffen the frame 3, longitudinal beams 5 are provided, to which the butts b are welded, intended for transporting the removable part of the bed 2 by a crane. The bed 1 consists of a base 7, which is a welded frame made of rolled metal and fixed patterns 8 fixed to the upper part 9 of base 7. The fixed patterns 8 are arranged with the same pitch, their upper edges are curved in shape deck section. The removable part of bed 2 is located on the top of bed 1 in such a way that its patterns 4 are located between the fixed patterns 8 of bed 1 with a half step between them, forming a single curve surface corresponding to the outer surface of the deck section. The fixed patterns 8 of the bed 1 are made with grooves for accommodating the longitudinal beams 5 of the movable part of the bed 2. The removable part of the bed 2 is connected to the bed 1 by means of a quick-release hinge 10.

The quick-release joint 10 consists of two eyelets 11 welded to the upper

part 9 of the base 7, the bracket 12, located between the lugs 11 on the same axis and the movable part 2 of the bed welded to the frame 3, the axis 13 made in the form

bolt, connecting two lugs 11 and bracket 12, washers 14 and nuts 15 screwed onto bolt 13.

The hull is manufactured as follows.

Assembled and welded on a mechanized production line, the links of the panel of plating (not shown) of the deck of the machine compartment are fed to the bed consisting of the moving part of bed 2, joined to each other and tacked to the leaves 7 and to the patterns 8 bed 1 using scallops overlap on patterns (not shown). Mark up with a well-known photoprojection method the traces of the joints of the set beams with the cladding. A set is installed on them and fastened by welding with a panel of the common board and among themselves. Install, weld glasses, cable boxes, studs, shanks, pendants, brackets, bridges from the side of the set.

5 After this, the section is detached from the patterns 8 of the bed 1 and together with the movable part of the bed 2 is turned over by a crane through two quick-release joints 10, in which the bracket 12 connected to the frame 3 of the movable part of the bed 2 rotates 180 °

0 through the axis 13, laying the deck section on the pedestal 16. Cut off and clean the tacking places, podvarivat and smooth out the seams on the back side. Set the saturation from the smooth side of the section - glasses, Navary, staples, sleeves. It is tested in a known manner for waterproofing, cleaned and primed. The primed zone unit together with the movable part of the bed 2 again turn over the crane around the hinge 10

0 to 180 ° to bed 1. Installation of equipment, machinery, pipes, fittings and appliances is in progress. The fabricated zone unit, together with the movable part of bed 2, is removed from the bed 1 by means of the eyes 6 by withdrawing the bracket 12.

 from the hinge 10 and is transferred by a crane to the slipway for docking with other zonal blocks.
