Installation precision control method for hawse pipe in total assembly stage

Abstract

The invention discloses an installation precision control method for a hawse pipe in an assembly stage, and the method comprises the steps: establishing a three-dimensional model of a bow block in Autocad software, and drawing a theoretical center line of the hawse pipe in the three-dimensional model through a hawse pipe top view and a hawse pipe side view; constructing a corresponding virtual large ground in the three-dimensional model according to the actual height from the hoisted bow section to the ground, and then accurately finding the actual center line of the hawse pipe in the actual assembly site according to the transverse projection size and the longitudinal projection size of the theoretical center line of the hawse pipe on the virtual large ground P3, and pulling the actual center line of the hawse pipe out through a steel wire; and mounting the hawse pipe on the bow block by taking the actual center line of the hawse pipe as a reference, so that the mounting precision of the hawse pipe is effectively improved, and the mounting effect of the hawse pipe is improved.

Description

Technical field [0001] The present invention relates to the field of ship construction techniques, and more particularly to a mounting accuracy control method of anchor tank in a header stage. Background technique [0002] In modern shipbuilding technology, some of the anchoring chain can be segmented, such as pre-installed in the segmentation stage, because the precision control is very easy to cause, the lower two-piece anchor chain mounting is installed, This not only affects the assembly of the anchor assembly, but also affects the success or failure of the subsequent reception anchor test. [0003] In this regard, after the upper and lower segments are performed, the interlocking problem of the anchor chain is mounted in the total group stage, but when installing anchor chain, the total section of the total section is designed according to the design drawings. The anchor tube opening position, anchor chain tube top view, and anchorial tubular side view are mounted, and the o...

Problems solved by technology

[0002] In modern shipbuilding technology, part of the anchor chain barrel design needs to span the upper and lower sections. If it is pre-installed in the segmental stage, it is very easy to cause the installation of the upper and lower anchor chain barrels to be misplaced due to the difficulty of precision control. This will not only affect the electric welding work of the anchor chain barrel assembly, but also affect the success or failure of the subsequent anchor pulling test

[0003] In this regard, after the general assembly of the upper and lower sections, the installation of the chain barrel at the stage of the general assembly can avoid the docking problem of the chain barrel. The location of the opening of the anchor chain barrel, the top view of the anchor chain barrel and the side view of the anchor chain barrel are installed. This operation method is based on the hard profile of the outer plate to position the hole, and the installation angle of the anchor chain barrel cannot be guaranteed.
