Problems solved by technology

[0002] In the prior art, during the construction of large ocean-going bulk carriers, the hatch covers are built on the ship. Before each batch is undocked, the welding and inspection of the hatch covers and related steel structures cannot be completed on schedule, resulting in In the case of passive construction at the wharf, the hatch cover is hoisted to the ship cover a day or two before undocking. In fact, it is just a simple cover, and the surface looks complete. No piping system and power mechanism have been installed. The phenomenon of adjustment, installation and rework

Abstract

The invention discloses an integrated leveling construction method for a translation type hatch cover system of a large ocean-going bulk cargo ship. The integrated leveling construction method comprises the following steps: 1, manufacturing a special jig frame on a foundation flat ground; 2, splicing a hatch coaming steel structure on the special jig frame, 3, pre-assembling a hydraulic power pipeline and a cable system on the foundation flat ground, 4, installing the hatch cover on the hatch cover steel structure; 5, installing a reinforcing plate on the hatch cover system, hoisting the hatchcover system to a deck to be assembled, assembled and welded, and fixing a pre-assembled hydraulic power pipeline and a cable system to the hatch cover system and the deck through clamping sleeves. The construction environment coefficient, the construction safety coefficient, the construction production efficiency and the productivity are all improved. A great effect is achieved on preassembly maximization of modern shipbuilding enterprises, the shipbuilding period is shortened, the process precision is guaranteed, and the requirements of ship inspection and shipowners are met.

Description

technical field [0001] The invention belongs to the technical field of ship building, and in particular relates to an integrated leveling method for large-scale ocean-going bulk carrier with translational hatch cover system. Background technique [0002] In the prior art, during the construction of large ocean-going bulk carriers, the hatch covers are built on the ship. Before each batch is undocked, the welding and inspection of the hatch covers and related steel structures cannot be completed on schedule, resulting in In the case of passive construction at the wharf, the hatch cover is hoisted to the ship cover a day or two before undocking. In fact, it is just a simple cover, and the surface looks complete. No piping system and power mechanism have been installed. The phenomenon of adjustment, installation and rework. Contents of the invention [0003] Aiming at the problems existing in the prior art, the present invention provides a large-scale ocean-going bulk carrie...
