Abstract

The invention discloses a method for accurately positioning a ship single shell block on a wharf. The method comprises the following steps that firstly, before the single shell block is hoisted, a jacking bracket is fixedly installed on the back face of an inclined side plate; secondly, a manhole is formed in the transverse bulkhead of the original ship; thirdly, jacking lower cross beam installation lines are drawn on the double-layer bottom and the broadside platform of the original ship correspondingly; 4, lifting the jacking lower cross beam from the large hatch and placing the jacking lower cross beam in place according to the mounting line; fifthly, a jacking device is placed on the jacking lower cross beam; sixthly, the single-shell block is hoisted into the large cabin; seventhly, a jacking upper cross beam at the double-layer bottom is moved in from a manhole of the transverse bulkhead; and 8, the floating crane is used for adjusting the single shell block in place, the single shell block is arranged on the jacking upper cross beam, and the jacking device is used for adjusting the position of the single shell block. The cross beam is in contact with the ship body structure, so that the deformation of the structure can be greatly reduced, and the subsequent field workload is reduced.

Description

technical field [0001] The invention belongs to the technical field of ship building, and in particular relates to a precise positioning method for a general section of a single hull of a ship at a wharf. Background technique [0002] After the main section of the single-hull fuel tank is hoisted into the main tank, it is necessary to trim the margin of the lower opening of the main section, and then carry out precise positioning to complete the assembly work. The conventional method is to use a floating crane for cooperation. This method lasts for a long time and cannot realize the fast hook release of the floating crane. Contents of the invention [0003] Aiming at the problems existing in the prior art, the present invention provides a method for precise positioning of the general section of the monohull of a ship at the wharf. According to the structural characteristics of the general section of the single hull and the configuration of existing tooling, the present inv...
