The invention discloses a design method for crack arrest steel plate splicing part hoisting. The design method comprises the following steps of S1, design of a crack arrest steel plate splicing part overturning lifter; S2, design of a mounting position of the crack arrest steel plate splicing part overturning lifter; S3, design of a connection mode of the crack arrest steel plate splicing part overturning lifter and a crack arrest steel plate splicing part; S4, design of a landing and overturning tool of the crack arrest steel plate splicing part; S5, an overturning scheme of the crack arreststeel plate splicing part; and S6, a disassembly technology of the crack arrest steel plate splicing part overturning lifter. By adopting the design method provided by the invention, the damage causedby contact of the crack arrest steel plate splicing part and a plate splicing steel platform is avoided; by designing the overturning lifter disassembly technology, the damage on the surface of crackarrest steel caused by the lifter in the disassembly process is effectively prevented; and the problem that the crack arrest steel plate splicing part is easily damaged in the hoisting process is solved, the reliability in the crack arrest steel plate splicing part hoisting and overturning process is improved, the crack arrest steel construction quality is facilitated, and the safety reliabilityof a ship in the operation process is improved.
Description
technical field [0001] The invention belongs to the field of shipbuilding, and in particular relates to a design method for hoisting crack arresting steel jigsaw parts. Background technique [0002] At present, container ships are developing in the direction of large-scale (VLCS). E47 crack arrest steel is used in the main deck of the torsion box and the hatch enclosure area. The crack arrest steel is a new type of high-strength steel. During the hoisting process of steel jigsaw components, the technical requirements for hoisting installation, hoisting welding, jigsaw parts turning over, hoisting removal, and weld grinding are more stringent than those of conventional high-strength steel. Replacement risk. At present, the hoisting design of crack arresting steel panel parts is mainly carried out by the following method: welding an ordinary C-type or D-type hoisting horse at one end of the crack arresting steel panel part, and using a In the full welding welding method, the...
