Large-scale anchor chock and anchor mouth lofting design method

Abstract

The invention provides a large-scale anchor chock and anchor mouth lofting design method. According to the lofting design method, a three-dimensional space lofting principle is used for completing theoretical model construction, and a specific three-dimensional projection lofting method is adopted to complete the lofting of an intersecting line of the anchor chock and a ship hull plate and a contour line of an anchor chock upper basal plane; and at the same time, a tangency included angle of the anchor mouth and the anchor chock and a hawse pipe is obtained, a contour line of the anchor mouthis drawn, a three-dimensional shaded surface of the anchor chock and anchor mouth is constructed, and three-dimensional modeling work of the hawse pipe, the anchor chock and the anchor mouth is finished. The large-scale anchor chock and the anchor mouth lofting design method solves the problem that the lofting of anchor chocks and anchor mouths of various types of ships is low in efficiency and poor in precision, precision data of feeding, machining, and assembly locating are provided for a site, the work of field proofing and adjustment is simplified, and the installation efficiency and precision of the anchor chocks and the anchor mouths are enhanced.

Description

technical field [0001] The invention relates to the technical field of ship anchor platform and anchor lip design, in particular to a lofting design method for a large anchor platform and anchor lip. Background technique [0002] At present, various types of large-tonnage ships generally adopt the anchorage storage form of anchor platform and anchor lip to solve the problem of anchor collision with the outer plate. Conventional anchor platform and anchor lip stakeout methods have complicated process, long stakeout cycle and low efficiency; moreover, designers use approximate stakeout principle, which results in poor stakeout accuracy. If there is too much margin, or increase the production of samples and sample boxes for on-site proofing and adjustment; and because the anchor platform and anchor lip are large in size and heavy in weight, and need to be installed on the outer surface of the hull plate, the anchor platform and anchor lip The installation, adjustment and proof...

Problems solved by technology

Conventional anchor platform and anchor lip stakeout methods have complicated process, long stakeout cycle and low efficiency; moreover, designers use approximate stakeout principle, which results in poor stakeout accuracy. If there is too much margin, or increase the production of samples and sample boxes for on-site proofing and adjustment; and because the anchor platform and anchor lip are large in size and heavy in weight, and need to be installed on the outer surface of the hull plate, the anchor platform and anchor lip The installation, adjustment and proofing of the anchor lip brought great difficulties, resulting in low production and installation efficiency of the anchor platform and anchor lip, and poor construction quality.
