Method for designing anchor base of unbalanced anchor with large holding power

Abstract

The invention relates to a method for designing an anchor base of an unbalanced anchor with large holding power. The method comprises the following steps: (1) confirming the deviation angle of a hawse pipe; (2) confirming the central coordinate point of an outlet at the lower end of the hawse pipe and the included angle between the hawse pipe and a vertical plane; (3) designing an anchor base panel; (4) designing angles related with the anchor base panel; (5) designing an anchor base coaming; (6) designing the internal members of the anchor base; and (7) designing an anchor mouth. According to the method, an anchor can be guaranteed to freely rotate, the requirement of smoothly storing the anchor in various states without locking can be met, the ship purchase cost is reduced at the same time, and the ship anchoring quality is improved.

Description

Technical field: [0001] The invention relates to the field of ships, in particular to an anchor platform design for an unbalanced anchor with a large holding force. Background technique: [0002] There are many types of anchors. Generally, transport ships mainly use Spek anchors and large holding power anchors. Due to the difference in the holding power of the two anchors, under the same product requirements, the Spek anchor is better than the high holding power anchor. The weight of the anchor is 25%, so the selection of high-grasp anchors is conducive to reducing the cost of ship construction, but the standard high-grasp anchor (AC-14) is an unbalanced anchor, and the design of its supporting anchor platform is relatively difficult. Generally, the shipyard A modified high-grasp balance anchor (non-standard) is often used, but it also leads to unsatisfactory retractable state of the anchor. It often happens that the anchor cannot be smoothly received on the anchor platfo...

Generally, shipyards A modified high-grasp balance anchor (non-standard) is often used, but it also leads to unsatisfactory retractable state of the anchor. It often occurs that the anchor cannot be received on the anchor platform smoothly, or the anchor grasp cannot be matched with the anchor platform.
