Integral single-segment pre-assembling method for anchoring platform

Abstract

The invention relates to an integral single-segment pre-assembling method for an anchoring platform. The integral single-segment pre-assembling method includes the steps: 1) dividing the ship body ofa bow into an upper segment and a lower segment, wherein the upper segment includes a forecastle deck and the position required by installation of the integral anchor platform, and the lower segment includes a main deck except for the overall installation position of the anchoring platform; at the same time, assembling the anchoring platform, an anchor mouth and a hawse pipe into the whole of theanchoring platform, wherein the planking segmental seams at the position where the overall anchoring platform is installed, corresponding to the upper segment and the lower segment, are isosceles trapezoids; 2) constructing the upper segment and the lower segment, wherein the anchor platform is integrally mounted on the upper segment; and 3) performing a normal total assembling on the upper segment and the lower segment. The integral single-segment pre-assembling method for an anchoring platform pre-installs the anchoring platform, the anchor mouth and the hawse pipe into one segment in the segmentation stage to avoid construction of cross-segmented closing joint, that is, in the stage of segmentation, the anchoring platform, the anchor mouth, the hawse pipe and part of the main deck structure are divided into one segment together, thus having the advantages of accurate positioning, low installation difficulty and short total assembling period.

Description

technical field [0001] The invention relates to the technical field of ship construction, in particular to an integral single-section pre-installation method of an anchorage. Background technique [0002] The anchor abutment, the anchor lip and the anchor chain barrel are collectively referred to as the anchor abutment as a whole. Among them, the anchor chain drum is used as the channel of the anchor chain when the ship is lifted and anchored, and the anchor chain drum is composed of the deck chain hole, the side chain hole and the cylinder. The anchorage is a boss structure located at the outlet of the outer plate of the anchor chain drum. Its function is to prevent the anchor from colliding with the outer plate when the anchor is lifted or dropped. An anchor lip is installed at the front end of the anchorage. The anchor lip is an elliptical annular structure located at the outlet of the outer plate of the anchor chain cylinder, which bears the collision force and friction...

Problems solved by technology

This process requires the disconnection of the anchor chain barrel, which is extremely inconvenient for the docking construction of the anchor chain barrel at the general assembly stage, and it is difficult to control the positioning of the anchor platform and the accuracy of the anchor chain barrel
