Bending-shaped outer plate assemblage and roll over method

Abstract

The invention discloses a bending-shaped outer plate assemblage and a roll over method. The bending-shaped outer plate assemblage comprises a structural plane and a non-structural plane, the structural surface is provided with a ribbed plate, when the bending-shaped outer plate assemblage is assembled, the non-structural plane is placed downward on a bed-jig, and two structural plane lifting ringsare mounted on the ribbed plate of the bending-shaped outer plate assemblage; the structural plane lifting rings are arranged in a vertical plane penetrating through the center of gravity and are located above the center of gravity; and two non-structural plane lifting rings are mounted on the non-structural plane of the bending-shaped outer plate assemblage, the non-structural plane lifting rings are uniformly distributed and arranged opposite to the center of gravity, and when the structural plane of the bending-shaped outer plate assemblage faces downward, the non-structural plane liftingrings are located above the center of gravity. According to the bending-shaped outer plate assemblage and the roll over method, the mounting manner of the lifting rings of the bending-shaped outer plate assemblage is simplified, the mounting number of the lifting rings is decreased, and complexity of on-site construction operation is reduced; and the bending-shaped outer plate assemblage and the roll over method facilitate angle adjustment of the bending-shaped outer plate assemblage, the labor-hour of on-site lifting is decreased, and the economic cost of bending-shaped outer plate assemblagemounting is reduced.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a method for assembling and turning over curved outer panels. Background technique [0002] In order to reduce the resistance in the water, the outer shell of the ship is usually designed as a curved surface, and the internal design of the curved surface supports the ribs. Especially in the engine room, bow and stern of the ship, this type of design is often used. For the convenience of calling, the curved shell plus supporting ribs constitute an assembly, which is usually called a curved outer plate assembly. [0003] like figure 1 As shown, a schematic diagram of a typical curved outer panel assembly 10 on the tire frame 2 . Set the tire frame 2 according to the curvature of the non-structural surface of the curved outer plate assembly 10, so that the upper surface of the tire frame 2 can be close to the non-structural surface of the curved outer plate assembly 10, and ...

AI Technical Summary

Problems solved by technology

[0007] To sum up, there are the following deficiencies in the turning over and hoisting of the curved outer panel assembly 10 at present: first, the curved outer panel assembly 10 is inconvenient to separate from the tire frame 2, which may cause the curved outer panel assembly 10 or tire Frame 2 is damaged; secondly, it is inconvenient to rotate 180° in the horizontal direction and turn over when the curved outer plate is assembled 10

Third, due to the four-point hoisting, it is difficult to adjust the angle of the curved outer panel assembly 10 during the hoisting process, and it is inconvenient to turn over and install the curved outer panel assembly 10
