Abstract

The invention provides an installation method of a ship sea chest grating. The installation method comprises the following steps that the size of the chest grating is determined, and the chest grating is manufactured; welding a hinged support and drilling a hinged hole in the hinged end of the hinged support; mounting a hinged eye plate; a fastener is installed, so that the door grid can be turned over and opened outwards with the fastener as a hinge point; and detecting whether the door grid collides with the sea chest or not in the opening process. And if collision occurs, the hinge holes are ground and lengthened until the door grid does not collide with the sea chest in the opening process, and then the door grid is installed. The method meets the requirements of ship bodies with different thicknesses and different curvatures, and the installation and debugging period of the door grid can be shortened. And the ship operation economy is improved. The sea chest grating solves the problem that the sea chest grating protrudes out of the hull structure in the installation process, economic benefits are improved, and application and popularization are facilitated.

Description

technical field [0001] The present application relates to the technical field of shipbuilding, in particular to a method for installing a ship seabed door grille. Background technique [0002] In the ballast water system and cooling water system in the ship, sea water is used as the flowing medium. In order to prevent the inhalation of sundries or marine organisms in the seawater, it is necessary to install a door grille on the seabed door of the seawater inlet. [0003] In order to ensure the pollution blocking effect, the way of reducing the gap between the door grille and the seabed door is usually adopted. When the door grill is clogged, it needs to be opened to clean the door grill. However, after reducing the gap between the door grille and the seabed door, the door grille will collide with the hull during the process of opening the door grille, causing damage to the hull, thereby increasing the cost of later hull maintenance. [0004] To sum up, it is necessary to ...
