Embodiment Construction

[0034] The invention discloses a manufacturing process of a bulbous bow reinforcement structure in an ice region, which involves a bulbous bow reinforcement structure in an ice region, such as Figure 1-3 As shown, it includes a strong rib frame 1, a rib 2, and four layers of the first layer of platform board 3, the second layer of platform board 4, the third layer of platform board 5, and the fourth layer that are vertically arranged on the strong rib frame 1 from top to bottom. Four-layer platform slab 6, the central longitudinal axis of the four-layer platform is fixed on the end face of the strong rib frame 1 by the platform bow middle longitudinal stringer; Plate 7 and several bulkheads 8 welded in pairs on both sides of the longitudinal plate 7, the bulkheads 8 are welded on both sides of the longitudinal plate 7 in a T shape; On the platform 2 between the strong rib frames 1, there are several outer plates 12, which cover the outer surface formed by the longitudinal gir...

Abstract

The invention relates to a process for manufacturing an ice zone bulbous bow reinforcing structure by sections. An angle steel combined horizontal tangent rib frame is adopted during bulbous bow sectioning, and a strong rib frame is used as a reference surface for lying manufacturing. The process for manufacturing by sections comprises the following steps: sectioning; putting a strong rib frame large assembly on a jig; putting a first layer platform large assembly on the jig and assembling; putting a second layer platform large assembly on the jig and assembling; putting a third layer platform large assembly on the jig and assembling: assembling a third layer platform plate and a third strong rib frame assembly into the third layer platform large assembly; putting a fourth layer platform large assembly on the jig and assembling; assembling a third middle longitudinal girder assembly and a fourth middle longitudinal girder assembly into a whole; mounting ribs; mounting an external plate. The process has the advantages that the angle steel combined horizontal tangent rib frame is adopted, and the strong rib frame is used as the reference surface for lying manufacturing, so that the production efficiency is improved, the period for constructing the bulbous bow by sections is shortened, and the shipbuilding speed is increased.

Description

technical field [0001] The invention relates to a segmental manufacturing process of a bulbous bow reinforcement structure in an ice region, specifically a bulbous bow reinforcement structure in an ice region that improves production efficiency, shortens the construction period of bulbous bow segments, and speeds up shipbuilding Sectional production process. Background technique [0002] Nowadays, more and more new ships need to meet the requirements of ice strengthening. The so-called ice strengthening refers to the ice layer and ice blocks formed by the freezing of sea water on the sea surface when the ship sails in the ice area. The strengthening measures adopted for the hull structure, main engine, shafting, gearbox, propeller, starting device and cooling water system. Usually, the bulbous bow structure is added to meet the ice strengthening requirements. Although the design meets the ice strengthening requirements, its construction is more difficult and cannot be b...
