Method for designing and manufacturing circular anchor mouths and right circular conical anchor beds

Abstract

The invention relates to the field of ship design and manufacturing, and particularly relates to a method for designing and manufacturing circular anchor mouths and right circular conical anchor beds. The method is implemented by designing and manufacturing a deck, a hull, a hawse pipe, an anchor mouth and an anchor bed, wherein the hawse pipe passes through the deck and the hull, and the anchor mouth and the anchor bed are arranged on the outer side of the hull and used for fixing anchors, the anchor mouth is circular, and the anchor bed is a circular bed formed in that way that a right-circular cone intersects with the anchor mouth and the hull, wherein the developed surface of the anchor bed is a part of a developed surface of the right-circular cone. The method disclosed by the invention has the advantages of abandoning the defects of the prior art that anchor mouths and anchor beds are designed and manufactured by manufacturing irregular sample box models, providing a systemic technological theory support for the designing and manufacturing of anchor mouths and anchor beds, solving the design and installation problems of anchor mouths and anchor beds which puzzle the shipbuilding industry for a long time, optimizing the production process, and improving the production efficiency.

Description

technical field [0001] The invention relates to the field of ship design and manufacture, in particular to a method for designing and manufacturing a circular anchor lip and a conical surface anchor platform. Background technique [0002] In shipbuilding technology, anchors are often positioned on the anchor platform and anchor lip at the bow, such as figure 1 As shown, it includes a deck 1, a hull 2, a chain anchor barrel 3 that runs through the deck 1 and the hull 2, and an anchor lip 5 and an anchor platform 4 that are arranged on the outside of the hull 2 ​​for fixing the anchor 6, and the anchor lip 5 is an anchor platform. 4, the rigid structure at the top, the side of the anchor 6 tightly fits on the anchor lip 5 when it is folded. [0003] Due to the complexity of the external line shape of the hull, especially the complex line shape of the bow, the design and manufacture of the known anchor platform and anchor lip are all completed by manufacturing models and manua...

AI Technical Summary

Problems solved by technology

[0003] Due to the complexity of the external line shape of the hull, especially the complex line shape of the bow, the design and manufacture of the known anchor platform and anchor lip are all completed by manufacturing models and manually setting out to modify the dimensions. For an anchor Innumerable schemes can be designed for the anchor platform and anchor lip for its positioning. During manufacture, the relevant parameters are determined by designing the model and modifying the size of the model. Since there is no systematic technical theory support, many anchor lips in the prior art The design is an irregular geometric figure, and the anchor platform is mostly a curved surface that cannot be developed, resulting in high processing difficulty and long processing time, which is not conducive to the progress of production activities
