Abstract
This article mainly introduces the application of 3D modeling technology in the lofting of large anchor chocks,anchor lips and complex anchor pockets.By utilizing the principle of 3D spatial lofting to complete the construction of theoretical models,a special 3D projection lofting method is used to complete the intersection line between the anchor chock,anchor pocket and hull outer plate,determine the position of the anchor lip,calculate the tangent angle between the anchor lip,anchor chock and hawse pipe,construct the surface of the anchor fittings,and complete the lofting work of the anchor chock,anchor pocket and anchor lip.This solves the problem of low efficiency and poor precision in the lofting of various types of ship anchor chocks and anchor pockets,provides accurate material cutting,processing and equipment positioning data on site,simplifies the field sampling and calibration work,and improves the installation efficiency and precision of the anchor chock,anchor pocket and anchor lip.
