Double-sided preassembling method for bulkhead guide rails on large container ship and bulkhead

Abstract

The invention relates to a double-sided preassembling method for a bulkhead guide rail on a large container ship. The bulkhead is a non-watertight bulkhead, the bulkhead is of a hollowed-out frame structure, and the installation precision of the bulkhead guide rail installed on the two faces is smaller than 7 mm. The method comprises the following steps: firstly, mounting a guide rail bracket on a horizontal jig frame of a compartment of the container ship; measuring levelness at a bay rib position datum line by taking one surface on which the guide rail bracket is mounted as a rear wall, and marking each hard gear of the bay by a punching point; then, the bay is adjusted to be horizontal again after the bay is turned over, the levelness of the guide rail frame located on the rear wall after installation is ensured, and the reference rib position line, the rear wall guide rail frame and the front wall guide rail frame to be installed are parallel to one another; therefore, the installation reference is determined, and the double-sided guide rail bracket is positioned and preassembled according to the found installation reference. The method is easy to operate, wherein guide rail preassembling can be completed in advance, the total assembling stage time is shortened, so that the pressure of a total assembling site is relieved, the building period in a dock is shortened, and the ship building efficiency is improved.

Description

technical field [0001] The invention relates to the field of shipbuilding, in particular to a double-sided preinstallation method for compartment guide rails of large container ships. Background technique [0002] As the construction period of large container ships becomes shorter and shorter, it is necessary to gradually shorten the construction period according to the characteristics of container ships. Container ships have high requirements for storage capacity control and a large number of compartments, which have always been a difficult point in the construction of the main hull. The guide rail installation is a key node that affects the integrity of the compartment, and the subsequent hanging box test and stacking box test. Installation At present, the guide rails of the compartments of container ships are pre-installed on one side in the segmented stage. Due to the high precision requirements and the large deformation of the compartments, the guide rails on the other...

Problems solved by technology

Installation At present, the guide rails of the compartments of container ships are pre-installed on one side in the segmented stage. Due to the high precision requirements and the large deformation of the compartments, the guide rails on the other side are installed in the general assembly stage, which greatly affects the total assembly time and the total tire position backlog time. If it is too long, the construction efficiency is low, and the compartment cannot be formed. The general section of the bottom and side of the container ship has a simple structure and a short assembly cycle, which will not be able to match the overall assembly time of the compartment, which will seriously affect the loading progress of the dock
