Embodiment Construction

[0017] In order to describe in detail the technical content, structural features, achieved objectives and effects of the present invention, the following detailed descriptions are combined with the embodiments.

[0018] Ship assembly is the process of assembling parts, subsections, and total sections of qualified hull parts to the hull. The hull assembly is divided into hull structure pre-assembly welding and berth assembly welding. The hull structure pre-assembly welding is divided into three processes: component assembly welding, segment assembly welding and general assembly welding. The main equipment used in the pre-assembly welding of the hull structure is lifting, electric welding, gas cutting and compressed air equipment, as well as pipelines, platforms and tire frames. Among them, the platform and the tire frame are the main process equipment.

[0019] The platform is generally a workbench with a certain level composed of cement foundation, section steel, steel plate, etc....

Abstract

The invention discloses a ship double bottom block assembly welding technology. The ship double bottom block assembly welding technology comprises the following steps of: presetting corresponding tire holders of the double bottom, marking a seam line mark on each tire holder, and starting to assemble external plates corresponding to the seam line marks on the tire holders, and welding the external plates; marking vertical and horizontal framework mounting lines on the external plates, and mounting a middle bottom girder; assembling vertical and horizontal frameworks at corresponding positions of the vertical and horizontal framework mounting lines, welding a front pressurizing row, welding the seam between the frameworks and the seam between the frameworks and the external plates, then, detaching the pressurizing row, correcting deformation, and fitting out block by block; hoisting inner bottom plates on the vertical and horizontal frameworks, marking block assembly locating lines on the inner bottom plates, and welding flying rings block by block; hoisting and turning over the blocks, placing the blocks on a platform, and welding the seams between the vertical and horizontal frameworks and the inner base plates, and the sealing run of the external bottom plates. With the adoption of the technology provided by the invention, the ship double bottom assembly efficiency is high, and the welding quality is good.

Description

Technical field [0001] The invention relates to the field of ship component installation and welding technology, in particular to a segmental assembly and welding technology for ship double bottom. Background technique [0002] Ship components are the main supporting components of ships and consist of thousands of parts. The assembly and welding of components is one of the main tasks of shipbuilding. The work load of hull assembly and welding accounts for more than 75% of the total work load of hull construction, of which welding accounts for more than half. Therefore, welding is a key task in shipbuilding. It is not only directly related to the quality of ship construction, but also to shipbuilding efficiency. The development process of modern shipbuilding technology is a process from manual operation to mechanization and automation. Since the 1950s, riveting has been replaced by welding in hull construction, which has improved the hull construction from the sporadic bulk asse...
