[0004] 2. After the general section is turned over and installed, it is directly covered on the door. Since the section is a large opening structure, the deformation will be large after turning over, which is very unfavorable to the accuracy of the door frame and is uncontrollable.
It takes a lot of manpower and takes 2 days to pull the door into place, which is very inefficient
[0006] 4. Install other accessories. Due to the deformation of the door frame when turning over and loading, the center line and positioning reference line need to be drawn again

Embodiment Construction

[0032] The method for installing a large watertight door of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the present invention cannot be limited by this.

[0033] The watertight door in the large watertight door installation method of the present invention is in figure 1 Draw the reference line and perform anti-state pre-installation in the state. After the watertight door and the general hull section are turned over and carried together, use the hoist and wire rope to fine-tune in situ. Position all attachments according to the guides. Then open the watertight door, install the compression strip, and weld the compression strip after confirming that the watertightness is correct.

[0034] The specific steps are as Figure 4 as shown, Figure 4 It is a flow chart of the installation method of the large watertight door of the present invention. As can be se...

Abstract

The invention relate to an installation method of a large watertight door. The installation method includes the steps that when a section is in a reverse total-assembly, the flatness, the center line and an installation reference line of a block door frame are marked; the watertight door is pre-embedded in the section in a reversely assembled manner to be restrained and fixed and carried by a block to be arranged on a ship; after block carrying and electrowelding submitting are finished, the watertight door is installed, and a hinge, an electric oil cylinder, a locking device and other accessories are located; and finally stainless steel pressing strips are installed. By means of the installation method, the feature of the total-assembly carrying stage of ship building is utilized to the maximum extent, the installation workload of the watertight door is lowered to the minimum, and the installation precision and quality are improved greatly; and by means of the installation method, the labor cost can be lowered greatly, and the influences on installation of the watertight door in different stages of ship building can be avoided.

Description

technical field [0001] The invention relates to ship construction, in particular to a method for installing a large watertight door in the construction of a container ro-ro ship or a ro-ro ship. Background technique [0002] At present, the installation of large watertight doors in the construction of large container ro-ro ships or large ro-ro ships mainly uses the following methods: [0003] 1. Put the watertight door on the deck of the ship in advance. [0004] 2. The main section is turned over and mounted directly on the door. Since the section is a large opening structure, the deformation will be large after turning over, which is very unfavorable to the accuracy of the door frame and is uncontrollable. [0005] 3. Use 6 hoists to pull the watertight door from the flat state on the deck to the upright installation position. It takes a lot of manpower and takes 2 days to pull the door into place, which is very inefficient. [0006] 4. Install other accessories. Due to...
