Large bulbous bow module

Abstract

The invention provides a bow module of a large-scale bulbous bow, belonging to the technical field of ship building. The bow module comprises a plurality of upper ribbed plates, a plurality of lower ribbed plates, a plurality of structural shapes, a plurality of reinforced plates, a plurality of center girders, a plurality of strong anti-collision materials, a plurality of weak anti-collision materials and a plurality of outer plates, wherein the structural shapes are arranged between the upper ribbed plates and the lower ribbed plates, the center girders are vertically arranged in the middle of the upper ribbed plates and the lower ribbed plates, the strong anti-collision materials and the weak anti-collision materials are arranged in a plurality of bilateral spaces formed by the upper ribbed plates and the lower ribbed plates, the strong anti-collision materials and the weak anti-collision materials are arranged with one another at intervals, the reinforced plates are arranged at the inner sides of the upper ribbed plates, the center girders and the strong anti-collision materials, and a whole frame is externally welded with the outer plates. The strong anti-collision materials and the weak anti-collision materials are distributed with one another in the shape of arc, and the ends of the strong anti-collision materials and the weak anti-collision materials are gradually furled. The module can be formed for once in a building way, can be welded by a plurality of workers at the same time, is high in efficiency, is basically molded for once, is higher in product quality, and is much shorter in production period.

Description

technical field [0001] The invention relates to a bulbous bow module, in particular to a bulbous bow module of a large ship with tens of thousands of tons, and belongs to the technical field of ship building. Background technique [0002] The bulbous bow of a 10,000-ton ship has complex lines and numerous structures. A series of technical problems, such as inability to assemble components and inability to weld, are prone to occur during construction, especially in the arc area of ​​the bow. According to the requirements of the specification, the bulbous bow anti-collision materials are arranged in an arc shape. The maximum distance between the two anti-collision materials at the arc cannot be greater than 320mm, and the ends are only about 70mm after the ends are gradually gathered. As a result, the gap between adjacent structures is too small to be welded or full Welding, so the current assembly method only has one piece of parts to be welded in sequence, resulting in extr...

Problems solved by technology

[0004] The problem to be solved by the present invention is that the manufacturing efficiency of the existing bulbous bow is low and the radian of one-time molding is poor.
