Abstract
Provided is an anchor for a ship that may facilitate retrieval of the anchor as a folding operation of the anchor is smoothly performed by improving a design of a contact portion such that a mechanical contact resistance of components that perform a folding operation of the anchor is minimized. Consequently, the anchor may be easily retrieved without cutting the wire or the iron chain, that is, without loss of the anchor in a situation in which the anchor arm is caught by an underwater structure not to be pulled out when the ship leaves a harbor after the mooring.
Claims7
An anchor for a ship including a shark having a structure in which one end of the shark is connected to a wire or an iron chain, and an anchor arm mounted to a lower end of the shark to be seated under the water to be fixed, wherein
- the shark includes a hollow cylindrical casing, a fixing cap is inserted into an opened upper portion of the cylindrical casing, the fixing cap is supported by a cap support member on a lower side thereof in the interior of the cylindrical casing, an elastic member is disposed on a lower side of the cap support member, a plurality of fixing pieces are disposed to form pairs on a radially outer surface of an end of the cylindrical casing, and third through-holes are formed at middle portions of the fixing piece,
- wherein shark upper rod passes through a first through-hole that passes through the center of the fixing cap and extend downwards, a lower end of the shark upper rod is located in a second through-hole that passes through the center of the cap support member, the lower end of the shark upper rod is coupled to an upper end of a shark lower rod disposed below the shark upper rod, the elastic member is disposed on a radially outer side of the shark lower rod, a shark end is formed on a vertically lower side of the elastic member, the shark end has a structure that is inclined such that it becomes narrower toward a radially inner side as it goes downwards, and the shark end is disposed to be surrounded by the cylindrical casing, except for a portion that is inclined to become narrower to a radially inner side,
- wherein the anchor arm is mounted between the fixing pieces to be foldable radially with respect to the cylindrical casing and the shark end,
- wherein the anchor arm includes an arm and a fluke, a crown in a curved form is formed at a fixed end of the arm, a fourth-through hole is formed at a middle portion of the crown, and in a state in which the crown is inserted between the fixing pieces, the anchor arm is mounted to be foldable in a radial direction with respect to the cylindrical casing and the shark end by a coupling bolt and inserted into the third through-holes of the fixing pieces and the fourth through-hole of the crown and a coupling nut, and
- wherein the shark end includes a first linear portion extending vertically downwards by a predetermined length, a second linear portion extending from a lower end of the first linear portion to a radially inner side by a predetermined interval to form a step and then extending vertically downwards, a first inclined portion extending to be inclined to a radially inner side from an end of the second linear portion, and a second inclined portion extending to be inclined to a radially inner side from an end of the first inclined portion, and the crown includes an arc-shaped curved portion at a portion that contacts the shark end, a third inclined portion extending from one radial end of the arc-shaped curved portion to be inclined to a radially inner side by a predetermined angle, a fourth inclined portion extending to a radially outer side to be inclined with respect to the third inclined portion, and a fifth inclined portion extending to a radially inner side to be inclined with respect to the fourth inclined portion
