Precision control method for cargo hold broadside segmentation carrying of multipurpose ship

Abstract

The invention discloses a precision control method for cargo hold broadside segmentation carrying of a multipurpose ship. The precision control method for the cargo hold broadside segmentation carrying of the multipurpose ship comprises the following steps of (a), manufacturing broadsides; (b), setting benchmarks of the broadsides; (c), forming support box mounting holes; (d), mounting support boxes; (e), setting a unified detection benchmark on a double-layer bottom; (f), carrying a first segment of the broadsides; (g), carrying other segments of the broadsides sequentially; (h), rechecking the broadsides segment by segment; (i), rechecking support blocks; and (j), finishing welding of the broadsides. By changing the traditional shipbuilding process, mounting baselines and support box mounting hole baselines are set and forming of the mounting holes and installation of the support boxes are completed before cargo hold broadside segmentation carrying, and each broadside is arranged on a ship bottom segment by segment and side by side; through the precision control over side-by-side arranging of the broadsides, the precision control over second-deck support blocks is achieved; and the precision control method for the cargo hold broadside segmentation carrying of the multipurpose ship has the advantages of being simple in process, convenient to manufacture, and high in precision of side-by-side arranging of the support blocks.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a precision control method for multi-purpose ship cargo hold side-mounted sections. Background technique [0002] A multi-purpose ship refers to a ship with multiple functions, that is, a ship that can simultaneously load two or more types of cargo can be called a multi-purpose ship. For the convenience of loading various types of goods, multi-layer second decks are required in the cargo holds of multi-purpose ships, and the second decks are supported by support blocks arranged on the sides, and the second decks are usually stacked on the double bottom of the cargo hold. When loading goods that are not suitable for heavy pressure or stacking, open the support block, pave the second deck with two or more layers, and place the goods on the second deck layer by layer. In order to ensure the stable loading of the goods, the second deck Flatness is extremely critical, and the fl...

Problems solved by technology

In the hull manufacturing process, the installation accuracy of the second deck support block and the support box is high, and the existing problem is that after the assembly of the side side and the bottom of the ship is completed, the support box installation hole is opened on the side side, and the support box is installed. Due to the high surface of the side wall, firstly, it is inconvenient to level and mark lines; secondly, scaffolding needs to be erected. The alignment accuracy of multiple support boxes, after installation, once the accuracy of the arrangement of the support boxes fails to meet the design requirements, it is necessary to cut and repair the hull side sections, which not only affects the beauty of the hull, but also consumes manpower and material resources. Great impact on the entire shipbuilding and docking cycle
