Description

Technical Field

[0001] The present invention relates to the technical field of shipbuilding, and particularly relates to a method for installing a ship side door and a ship. Background Art

[0002] Ro-ro car carriers are provided with side doors at the side position, and the side doors can be used as one of the loading and unloading channels for cars. The side door includes a side door body and outfitting parts (hinges, power devices, etc.), and the side door body is recovered and lowered through the outfitting parts. The installation accuracy requirements for the above side doors are relatively high, which are mainly reflected in two aspects: one is the matching degree of the squareness between the side door body and the side position of the hull, and the other is the matching degree between the side door body in the recovered state and the side line of the hull.

[0003] Currently, the installation of the commonly used side doors is carried out in the following manner: on the one hand, the side of the hull is divided into a general block and multiple sub-blocks, and as the general assembly and erection operations progress, the installation area of the side door on the side of the hull is formed; on the other hand, when the side door body is being built, it needs to be manufactured according to the design requirements, and the dimensions, flatness, etc. are inspected and accepted. After passing the inspection, it is transported to the general assembly site. When the side door is ready for hoisting, the side door is hoisted by a crane, and the outfitting parts such as hinges on the side door are aligned with the hinge eye plates on the side of the hull, and then through multiple adjustments, the side door is adjusted to meet the usage requirements.

[0004] The above method for installing the side door has the following problems: First, during the construction of each mechanism of the hull, there will be different degrees of deformation, resulting in a low installation matching degree between the side of the hull and the side door. This requires a large amount of rework and adjustment in the follow-up to adjust the matching degree between the side of the hull and the side door to meet the requirements. The debugging process is cumbersome and the efficiency is low. Second, during the installation and debugging of the side door, if problems are found, a large amount of high-altitude work is often required during adjustment, which poses a safety hazard and the work efficiency is low. Finally, during the debugging process of the side door, the crane needs to be occupied for a long time, resulting in too low turnover and utilization rate of hoisting equipment such as cranes.

[0005] Therefore, there is an urgent need for a method for installing a ship side door and a ship to solve the above problems. Summary of the Invention
