Problems solved by technology

Because the sealing plate needs to be installed after the azimuth thruster is installed, and at this time, because the azimuth thruster blocks the construction space above the sealing plate, the construction cannot be carried out from above the steering engine room, and the sealing plate and the ship can only be carried out under the bottom of the ship. The bottom plate is welded on one side, but there are dual effects of vibration of the azimuth propeller and impact of water flow in this area, and single-sided welding cannot meet the structural strength requirements

Abstract

The invention relates to the technical field of ship construction, and discloses a method for mounting a lower sealing plate of a base of a full-revolving propeller, which comprises the following steps of: manufacturing a sealing plate, manufacturing a fillet welding steel liner, manufacturing a butt welding steel liner and a plug welding steel liner, mounting a reinforcing toggle plate, mounting the fillet welding steel liner and mounting the sealing plate. The construction difficulty can be effectively reduced so that welding construction can be completed, and meanwhile the installation quality and the structural strength of the sealing plate structure are guaranteed.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a method for installing a lower sealing plate of an azimuth thruster base. Background technique [0002] In order to improve the flexibility of ship navigation operations and meet the requirements of DP dynamic positioning in ship regulations, most offshore engineering ships use electric propulsion systems to provide propulsion power for ships. The azimuth thruster is an important part of the electric propulsion system. Usually, the azimuth thruster is installed in the steering gear cabin at the stern of the ship, and is connected and fixed with the hull structure through the base of the azimuth propulsion device. In order to ensure the installation of the azimuth thruster, It is necessary to open a larger opening under the bottom plate of the ship to ensure that the upper half of the azimuth thruster can pass through the bottom plate of the ship as a whole and be installed ...
