Deck face hatch cover system installing method

Abstract

The invention provides a deck face hatch cover system installing method. The method comprises the steps that firstly, hatch covers are manufactured, concretely, longitudinal and transverse center lines and involution lines of the hatch covers are marked; secondly, an outfitting piece is installed on a ship in advance, concretely, longitudinal and transverse center lines and hatch cover theoretical lines of hatch coamings are marked, the positioning size of the outfitting piece is measured, and the outfitting piece is directly assembled and welded before the hatch covers are installed to the ship; thirdly, the hatch covers are installed on the ship, concretely, the hatch covers are hoisted to the ship to correspond to the hatch cover theoretical lines at the front end and the rear end of the upper hatch coaming, separating seams of the port and starboard hatch covers are adjusted to correspond to the longitudinal center line on a hatch coaming panel, and the contact gap between supporting blocks and press depths of rubber strips are adjusted to meet tolerance requirements. By the adoption of the deck face hatch cover system installing method, it can be ensured that the measurement standard needed when the outfitting piece is manufactured and the standard needed when the outfitting piece is preinstalled on the ship are consistent, the period of installing the outfitting piece on the ship is shortened, the percent of pass of installation precision and quality is improved, and hatch cover repeated hoisting and conveying frequency can be reduced.

Description

technical field [0001] The invention relates to construction engineering in the shipbuilding industry, in particular to a method for installing a deck surface hatch cover system. Background technique [0002] At present, the installation process of the traditional hatch cover system is generally followed by building the hatch enclosure, making the hatch cover, installing the hatch cover on board, installing outfitting parts, and applying for inspection and so on. During the installation of outfitting parts, due to the need to repeatedly lift the hatch cover, it is easy to cause the hatch cover to deform, which will damage the flatness of the subsequent installation of the box seat on the hatch cover, and also affect the matching between the hatch cover and the hatch coaming , the crane resources take up a lot, and the stacking site takes up a lot; in addition, since the hatch cover is put on the ship, the positioning reference of the outfitting is generally based on the actu...

Problems solved by technology

During the installation of outfitting parts, due to the need to repeatedly lift the hatch cover, it is easy to cause the hatch cover to deform, which will damage the flatness of the subsequent installation of the box seat on the hatch cover, and also affect the matching between the hatch cover and the hatch coaming , the crane resources take up a lot, and the stacking site takes up a lot; in addition, since the hatch cover is put on the ship, the positioning reference of the outfitting is generally based on the actual position where the hatch cover is installed, and the measurement reference of each outfitting cannot be compared with the installation on the ship. The benchmark is unified, and the positioning dimensions can only be measured one by one, which limits the construction period of the berth, dock and wharf
