Installation tooling and installation method of opening and closing hinge for ships

Abstract

The invention provides a marine opening and closing hinge installation tool and method. The installation tool comprises a positioning shaft (4) and positioning reinforcing plates (5), positioning holes (6) are formed in the positioning reinforcing plates (5), and positioning shafts (4) penetrate through the positioning holes (6) in the positioning reinforcing plates (5) and pin holes (2) in a plurality of hinge components (1). The installation method comprises the steps that reference lines are marked on the bow or stern and a gangplank (3) of a ship, accurate positioning during opening and closing hinge installation can be achieved according to the corresponding relation between reference lines on the tool and the reference lines on the ship, the phenomenon that different shrinkages and stresses generated in the construction process, and vertical and front-back size shrinkage malposition are avoided, hinge perpendicularity and center line parallelism can be ensured, the precision is effectively controlled, and installation pairing of the hinge is achieved finally.

Description

technical field [0001] The invention relates to the field of ship building technology, in particular to an installation tool and an installation method of an opening and closing hinge for a ship. Background technique [0002] With the continuous development of the defense industry, a new generation of multi-functional and diversified product ships with new technological content is constantly emerging. The breakthrough of the corresponding high-tech manufacturing process has become the technical bottleneck of the product ship under construction. The opening and closing device of the bow and stern of the all-aluminum heavy-loading lift ship—the springboard is an important and key conveying channel for the heavy-loading vehicle to lift the ship up and down. Heavy-duty vehicles pass through. The opening and closing springboard structure is welded with aluminum alloy, and the connection with the main hull is completed by three pairs of cast aluminum hinges, and relevant power eq...
