Lofting production method of anchor recess of planking thickness line of hull

Abstract

The invention discloses a lofting production method of an anchor recess of a planking thickness line of a hull. The lofting production method comprises the following steps: (1) line type lofting of an anchor recess region adopts a method of deducting the planking thickness line of the hull; (2) the line type of the anchor recess takes an A-A section of a center line of a hawse pipe as a reference, and projection is carried out on a three-directional line type deducting the planking thickness; (3) the protection of a section of an anchor mouth takes a 7# section and a 3# section of the center line of an anchor pipe as reference, and an origin of the outlet of the anchor pipe is a constant value; (4) the center line of the anchor pipe and a rib position of a water line are marked on a tapping sample; (5) the anchor mouth is located on the outlet point of the anchor pipe of the planking of the hull; (6) values are reasonably corrected by a cat anchor test; (7) the anchor recess is installed. According to the lofting production method, the validity and the success rate of the cat anchor test are improved, the design quality is improved, the production cost is reduced, the production cycle is shortened, the production design is matched with a production method of a production department, so that anchor release, anchor raise and mooring of a ship can be successfully carried out after the anchor recess is installed.

Description

technical field [0001] The invention relates to shipbuilding, in particular to a method for setting out and making ship curvature linear anchor holes. technical background [0002] The anchor hole of the ship is one of the most difficult components in the design of ship outfitting. The ship anchor hole needs to go through the ship model test to determine the relevant anchor pipe centerline, positioning angle and data in the design stage. However, due to the curvature of the hull line shape, the center line of the anchor pipe and the positioning angle space dimension of the exit point of the hull plate need to be obtained during the lofting stage, and the model must be made, and the anchorage test can be used to verify the correctness of the positioning angle and space dimension. or not. [0003] A certain type of ship is a ship under construction. Its bow is pointed and thin, the line curvature, and the line shape of the area above the main deck is in a reverse bending S sh...

AI Technical Summary

Problems solved by technology

In the previous anchor hole setting out process, due to the short anchor chain pipe and the small angle between the center line of the hull and the large change in the curvature of the curvature of the anchor hole exit The upward trajectory is unstable, and the anchor fluke and the anchor lip are not submissive

And the deviation of some positioning values ​​cannot be reflected in the 1:3 wooden sample box anchor test, which brings troubles to on-site assembly and anchor test at the wharf

During the construction of the first ship, during the actual sample test of the anchor in the dock and the wharf, it was found that the upward trajectory of the anchor pipe was unstable, and the anchor was offset and stuck. At this time, suspended work was carried out on the wharf of the Huangpu River to correct the upward trajectory of the anchor. , and the anchor chain pipe and the anchor lip have been positioned, making it more difficult to determine the spatial positioning size, only the anchor lip can be adjusted, and it is more difficult to increase or decrease the thickness of the anchor lip
