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

Dependent claims

An anchor for a ship, the anchor comprising:

a shank having a structure in which one end of the shank is configured to be connected to a wire or an iron chain;
and
an anchor arm mounted to a lower end of the shank to be seated under water to be fixed,
wherein the shank includes a hollow cylindrical casing, a fixing cap inserted into an opened upper portion of the cylindrical casing, the fixing cap being supported by a cap support member on a lower side thereof in an interior of the cylindrical casing, an elastic member disposed on a lower side of the cap support member, a plurality of fixing pieces disposed to form pairs on a radial outer surface of an end of the cylindrical casing, and a first through-hole formed at a middle portion of one of the plurality of fixing pieces,
wherein a shank upper rod passes through a second through-hole that passes through a center of the fixing cap and extends downwards, a lower end of the shank upper rod is located in a third through-hole that passes through a center of the cap support member, the lower end of the shank upper rod is coupled to an upper end of a shank lower rod disposed below the shank upper rod, the elastic member is disposed on a radial outer side of the shank lower rod, a shank end is formed on a vertical lower side of the elastic member, the shank end has a structure that is inclined such that it becomes narrower toward a radial inner side as it goes downwards, and the shank end is disposed to be surrounded by the cylindrical casing, except for a portion that is inclined to become narrower to the radial inner side,
wherein the anchor arm is mounted between the fixing pieces to be foldable radially with respect to the cylindrical casing and the shank 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 anchor 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 shank end by a coupling bolt and inserted into the third through-hole of one of the fixing pieces and the fourth through-hole of the crown and a coupling nut, and
wherein the shank 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 the radial inner side by a predetermined interval to form a step and then extending vertically downwards, a first inclined portion extending to be inclined to the radial inner side from an end of the second linear portion, and a second inclined portion extending to be inclined to the radial 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 shank end, a third inclined portion extending from one radial end of the arc-shaped curved portion to be inclined to the radial inner side by a predetermined angle, a fourth inclined portion extending to a radial outer side to be inclined with respect to the third inclined portion, and a fifth inclined portion extending to the radial inner side to be inclined with respect to the fourth inclined portion.
