Problems solved by technology

However, during the construction and installation of side doors in the past, it was often difficult to match the line shape of the side door with the hull shell, and it was difficult to ensure the concentricity of the shaft hole of the hinge eye plate. Therefore, a high-precision construction method is urgently needed to solve the problem. The above technical issues

Abstract

The invention discloses a high-precision building method for a ship gangway. The high-precision building method comprises the following steps that step 1, a gangway jig frame is manufactured; step 2, reverse deformation is set for the gangway jig frame; step 3, holing is conducted on the ship body section outer plate; step 4, a side port main board and a ship body section outer board are laid on the same tire; step 5, the ship body section outer plate is assembled and welded, the sizes of the ship body section outer plate before and after welding are measured, and the ship body section outer plate is hoisted away when the sizes of the ship body section after and before welding are within the error range; step 6, a gangway main plate is assembled and welded; step 7, a hinge is installed and concentricity measurement is carried out; step 8, a gangway positioning involution line is manufactured; and step 9, pre-assembly is conducted on the gangway main plate and the ship body section outer plate. According to the method, the goodness of fit between the mounted gangway and a complex linear ship body is improved, so that the watertight performance and the overall attractiveness of a ship body outer plate are guaranteed, and the hoisting efficiency of the gangway in the final assembly carrying stage is improved.

Description

technical field [0001] The invention belongs to the technical field of ship building, and in particular relates to a high-precision building method for a side door of a ship. Background technique [0002] Large side doors are generally located on both sides of large ro-ro ships, ro-ro ships, and dock-type landing ships. When opened, they are used for the passage of ro-ro materials, equipment and personnel between the ship and the wharf. The surface is flush with the perimeter hull plating as part of the hull plating. However, during the construction and installation of side doors in the past, it was often difficult to match the line shape of the side door with the hull plate, and it was difficult to ensure the concentricity of the shaft hole of the hinge eye plate. Therefore, a high-precision construction method is urgently needed to solve the problem. the above technical problems. Contents of the invention [0003] Aiming at the problems existing in the prior art, the p...
