Description

Apparatus for heaving anchor in vessel}

The present invention relates to an anchor recovery device of a ship, and more particularly, it is not only to facilitate the drawing work by installing a structure for guiding the shank portion of the anchor to the outside by hovering outside in the hose pipe of the hull bow portion. The present invention relates to an anchor retrieval apparatus for a ship that can greatly shorten the time required for the ship.

In general, various structures supported by the sea, such as ships or offshore structures, are provided with anchors, which are a kind of mooring apparatus, and these anchors have a constant radius of water in which the hull anchored against external forces caused by wind or tidal currents is anchored. It can be used for various purposes, such as emergency control, which allows the user to stay safely inside or to stop the operation of the hull in case of emergency.

Such anchors can be broadly classified into stock anchors and stockless anchors. First, the stock anchor has a shank connected via a hull and a chain, a heavy weight Fluke formed approximately orthogonally to a lower end of the shank, and an intersecting shank at an upper end of the shank. It is formed in the direction is provided with a stock (Stock) to create a gripping force by digging into the sea bottom when mooring. The stock anchors are called cruciforms according to their external characteristics by shank and stock and are mainly used in small ships.

And the stockless anchor is connected to the shank through the hull and chain, an arm disposed in the direction crossing the shank at the lower end of the shank and rotatably coupled at a predetermined angle relative to the shank, and the shank at both ends of the arm and It has a fluke protruding in a parallel direction to form an approximately mountain shape. In this case, the arm supporting the fluke in the stockless anchor rotates at a certain angle with respect to the shank, so that the bills on both sides of the fluke dig into the sea floor during mooring to produce the proper gripping force. Stockless anchors are also commonly used in large ships.

On the other hand, such an anchor is stored in the hose pipe (Hawse pipe), which is referred to as the crushing hole of the hull, and exits to the outside along with the chain when mooring. FIG. 1 shows an example in which a stockless anchor is disposed at the center of a bow portion like a conventional high speed boat or a high speed boat.

As shown in the figure, in the case of the high speed boat in which the anchor is not positioned at both sides of the hull bow portion 51 and located at the center of the bow portion, the linear shape of the bow portion is made sharp to reduce resistance, and the buried bell mouth (Bell mouth, 53).

In addition, the bow portion 51 is provided with a hose pipe 57 disposed in a direction penetrating the hull toward the bow portion 51 from the deck 55 of the ship, the inlet of the hose pipe 57 is the bell It is located above the mouse 53.

In addition, by using the inner space of the hose pipe 57, the chain 59 is connected to the anchor so as to be movable, the chain 59 is coupled to the anchor shank 61 of the anchor portion by the end of the anchor The arm 63 and the fluke 65 together with the shank 61 form a structure supported by the chain 59.

Therefore, when the chain 59 is released by the operation of the nursery provided in the deck 55 during mooring, the anchor with the chain 59 is pulled out of the bow portion 51 through the hose pipe 57. It descends towards me and the sea floor. On the contrary, after the use of the anchor is recovered, that is, during the seedling, the chain 59 is wound up through the hose pipe 57 to the deck 55 through the operation of the seedling machine, and together with the chain 59 The anchor will rise as well.

However, the shank 61 portion of the anchor in such a series of processes will cause a loud noise while colliding with the inlet protrusion of the bell mouth 53 located in the bow portion (51). In addition, since the shank 61 portion of the anchor does not properly enter the inside of the hose pipe 57, a series of operations for holding the entrance direction of the shank 61 in place must be additionally performed. However, this work takes about 30 minutes for a high speed boat. That is, the delay of the drawing work as described above is such that the upper end portion of the anchor shank 61 which is connected to the chain 59 abuts the upper part of the inlet of the hose pipe 57 and the lower portion of the portion connected to the chain 59. The shank 61 located at is a phenomenon due to the fact that two-point contact with the front end of the bell mouth 53 occurs at the same time to prevent the entry of the shank 61 into the hose pipe 57.

Therefore, the additional time required to accurately insert the shank 61 portion of the anchor into the inside of the hose pipe 57 at the time of emergence will result in delaying the ship dispatch in case of emergency. There is an urgent need for improvement.

Accordingly, the present invention has been made in view of the above-mentioned matters, and the shank portion of the anchor is more naturally natural when the anchoring work is carried out through the sliding guider installed to be protruded into the hose pipe from the bell mouse located at the bow portion of the hull. The purpose of this method is to facilitate the drawing work and to greatly reduce the time required for the work by allowing the inside of the pipe to enter the pipe so that the ship can be dispatched more quickly.

The present invention for achieving the above object, the bell mouse protruding outward from the center of the bow portion of the hull, a hose pipe installed inside the bow portion to be able to communicate with the bell mouse and allow the outflow / mouth of the anchor, and And a shank supported by a chain movable through the hose pipe, the hose pipe having a sliding guider which can be projected out of the hull toward the bell mouth therein, and the sliding to the hose pipe. The hauler of the guider exits to the outside during mooring, and is stored inside the hose pipe upon contact with the coupling portion between the shank and the fluke.

In the present invention, the sliding guider has a hollow body for movably guiding the chain and the anchor, and a locking piece protruding from the side of the hollow body to the outside, the hollow body has an open top It has a cross-sectional structure of concave shape.

In the present invention, the hose pipe is inserted into the locking piece to form a long hole for movably coupling the locking piece in the hose pipe, and the maximum appearance of the sliding guider from the inlet of the hose pipe The distance is set to be greater than the protruding length of the bell mouse in the bow portion.

The present invention is suitable for the anchor recovery device of the ship, such as a high speed boat or a high speed boat in which the linear shape of the hull bow portion is sharp and anchorable to the center of the bow portion. Through the sliding guider protruding to the outside of the bow portion can naturally enter the inside of the hose pipe without hitting the entrance of the bell mouse, it is possible to significantly reduce the time required for the drawing work. In particular, the present invention is able to contribute significantly to the performance of the intended purpose by enabling a quick maritime dispatch in the event of an emergency by reducing the time required for the recovery of the anchor.

In addition, the present invention prevents the occurrence of unnecessary noise by preventing the shank portion from hitting the bell mouth inlet protruding into the bow portion of the hull during the drawing work of the anchor, and of the anchor by the collision involved in the conventional shank portion and the bell mouth inlet. Damage can be eliminated more aggressively, providing an economic advantage that can maximize the service life of the facility by extending the endurance life of the anchor.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying exemplary drawings.

As shown in the figure, the anchor recovery device of the ship according to the present invention is applied to a ship having a buried bell mouse, in the case of a ship having a sharp linear hull 10, such as a high speed boat or a high speed ship, A buried bell mouth 12 is formed at the center of the bow portion 10, and the bow portion 16 of the hull is arranged in a direction penetrating the hull toward the bow portion 10 from the deck 14. ) Is installed, the inlet of the hose pipe 16 is located above the bell mouth (12).

In addition, a chain 18 connected to an anchor is installed to be movable by using an internal space of the hose pipe 16, and the chain 18 has one end of a nursery (not shown) installed at the deck 14 of the hull. And the other end is coupled to the anchor shank 20 to simultaneously support the arm 22 and the fluke 24 of the anchor.

That is, the anchor is a bag-shaped shank 20 is coupled to the end of the chain 18, the arm 22 is rotatably coupled at a specific angle at the lower end of the shank 20, and the At both ends of the arm 22 there is provided a fluke 24 extending in a direction substantially parallel to the shank 20. At this time, the chain 18 is connected between the nursery installed on the deck 14 and the end of the shank 20 of the anchor to the mooring operation to lower the anchor in water through the operation of the nursery, or the drawing work to pull up to the hull on the contrary It makes each possible.

On the other hand, the hose pipe 16 has a sliding guider 26 formed in a separate structure that can be mounted to the outside of the hull toward the bell mouse 12 therein, more specifically the sliding guider 26 ) Is movably installed outwardly relative to the hose pipe 16 at a position confined inside the inlet adjacent to the bell mouth 12 of the entire portion of the hose pipe 16. In this case, it is preferable that the maximum possible distance of the sliding guider 26 from the inlet of the hose pipe 16 is set larger than the protruding length of the bell mouth 12 in the bow portion 10.

Accordingly, the sliding guider 26 exits from the inlet of the hose pipe 16 together with the chain 18 and the shank 20 at the time of mooring, as shown in FIG. As shown in FIG. 2, the chain 18 and the shank 20 are stored inside the inlet side of the hose pipe 16. To this end, the sliding guider 26 has a hollow body 26a for movably guiding the chain 18 and the shank 20 as shown in FIG. 3 and an outer side at the side of the hollow body 26a. It has a locking piece (26b) protruding into the support to the hose pipe (16).

In addition, the hose pipe 16 forms a long hole 16a for movably guiding the locking piece 26b inside the hose pipe 16 by inserting the locking piece 26b therein. In this case, the long hole 16a is formed to have a distance corresponding to the movement stroke of the sliding guider 26 in the longitudinal direction from the inlet of the hose pipe 16 to the inside. In particular, the sliding guider 26 is set as a hollow body 26a having a yaw-shaped cross-sectional structure of which the top is open in the form of a cross section, whereby the chain 18 and the shank 20 therein. ) Guides the movement, and the engaging pieces 26b are formed on both sides to enable smooth movement through engagement with the long holes 16a formed in the hose pipe 16.

Therefore, if the chain 18 is released by the operation of the nursery provided in the deck 14 during mooring, the anchor with the chain 18 through the hose pipe 16 to the outside of the bow 10 Descending towards the sea floor generates the gripping force required for anchoring. At this time, the sliding guider 26 exits from the inside of the hose pipe 16 to the outside through the inlet. That is, the sliding guider 26 protrudes to the outside through the force of the self-weight accompanying the installation angle of the hose pipe 16.

On the contrary, when the chain 18 is wound by the operation of the nursery during drawing, the sliding guider 26 is also stored together with the chain 18 into the hose pipe 16. In this process, the shank 20 of the anchor is in the manner of one-point contact with the end portion of the sliding guider 26 whose upper end portion exits from the hose pipe 16 together with the chain 18. Due to being supported, the shank 20 will not collide with any part of the bow 10, including the bell mouse 12. Subsequently, the shank 20 of the anchor enters the body 26a of the sliding guider 26 while pivoting in the upward direction toward the end of the sliding guider 26.

This process is further progressed, and the entrance of the shank 20 together with the chain 18 into the body 26a of the sliding guider 26 is followed by the operation of pulling the chain 18 by the dresser further. The sliding guider 26, including the chain 18 and the shank 20, is also housed inside the ozone pipe 16, and then only the arm 22 and the fluke 24 portions of the anchor 10 are located in the bow portion 10. ) Is supported as it is exposed to the outside. That is, when sliding, the sliding guider 26 is provided with an action force due to contact with the engagement portion between the shank 20 and the fluke 24 so as to correspond to the movement direction of the chain 18. ) Can be stored inside.

As a result, the chain 18 and the shank 20 enter the correct position toward the inside of the hose pipe 16 through the sliding guider 26 protruded outwardly from the hose pipe 16 at the time of drawing. In particular, the connection portion between the chain 18 and the shank 20 can be supported only in the tip portion of the sliding guider 26, which is protruded to the outside, so that the bow 10 and the bell mouse 12 can be supported. Unnecessary contact is eliminated to reduce the occurrence of abnormal noise due to the collision as well as to significantly reduce the time required for the drawing work.
