Description

  The present invention relates to an anchor stopper of a ship, and more specifically, after an anchor chain with a hook connected to the tip is wound up by a winder from an anchor chain lifting opening opened on the deck of the ship, In particular, the anchor stopper that holds the dredge on the side of the ship, in particular, the work to hold the dredge on the ship's side can be done in a short time with the worker standing up. The anchor stopper is securely held.

  As an anchor stopper for holding the anchor on the side of the ship, the one shown in FIG. 7 is conventionally known. In FIG. 7, first, the anchor chain 5 is wound up through the pulling port 3 by a winder (not shown), and the anchor (not shown) connected to the tip is lifted to the side of the ship. Next, after the anchor chain 5 is temporarily fixed by the chain stopper, the wire 100 having one end connected to the eye plate 103 of the deck 2 via the turnbuckle 101 is passed through the anchor chain 5. Then, the other end of the wire 100 is hooked on the cleat 102, and the turnbuckle 101 is tightened to strengthen the anchor chain 5, thereby holding the anchor on the side of the ship.

However, in the above-described conventional anchor stopper, when passing the wire 100 through the anchor chain 5 or when tightening the turnbuckle 101, an operator must bend over and work. This is not good, and it takes not only a long work time of 2 minutes or more, but also the wire 100 is loosened, resulting in poor fixing of the heel.

  Therefore, the problem to be solved by the present invention is a state in which the worker is standing on the side of the ship, and can be carried out in a short time of around 30 seconds, reducing the work effort, It is an object of the present invention to provide an anchor stopper which can be securely held on the side surface of the ship, and thus can contribute to safe operation of the ship, and which has improved the above-described drawbacks of the known technology.

In order to achieve the above-described problems, according to the present invention, an anchor stopper that winds up an anchor chain having a hook connected to a tip from an anchor chain lifting opening opened on a deck of a ship and pulls the hook to the side of the ship and holds it. In the above, a support base having an operation surface to which a double nut is fixed and extending in the vertical direction is installed on the deck substantially perpendicularly to the deck of the ship, and a screw rod is inserted into the operation surface through the double nut. The screw rod is screwed onto the anchor chain that extends from the collar to the lifting port almost on the extension line, and the handle is fixed to one end on the operation surface side of the screw rod, and the other end is made of a U-shaped pawl. A chain with a piece at the tip is connected, and after locking the U-shaped pawl of the locking piece to the anchor chain wound up on the deck, the handle is operated to check the chain. This makes it possible to hold the anchor on the ship's side in a short time, especially when the worker stands up, reducing the work effort and ensuring that the anchor is on the side of the ship. It is retained.

  The anchor stopper of the present invention engages the anchor chain with a U-shaped pawl on the anchor chain wound up by the winder on the ship deck, and then operates the handle to pull the chain. Because it was made to be tense, the work to hold the dredge on the side of the ship can be done in a short time of around 30 seconds with the worker standing up, reducing the work effort, and ensuring that the dredge is on the side of the ship For this reason, the effect that it can contribute also to the safe operation of a ship can be show | played.

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

  FIG. 1 is a plan view showing a use state of an anchor stopper according to the present invention in a ship. FIG. 2 is a plan view of the anchor stopper according to the present invention used in FIG. FIG. 3 is an enlarged plan view of the anchor stopper according to the present invention. FIG. 4 is an enlarged plan view of a state in which the anchor stopper of FIG. 3 is tensioned by a handle operation. FIG. 5 is a plan view and a side view showing the locking piece of the anchor stopper according to the present invention. 6A and 6B show a state in which the locking piece of the anchor stopper according to the present invention is locked to the anchor chain, where FIG. 6A is a side view and FIG. 6B is a plan view. FIG. 7 is a plan view showing a conventional anchor stopper.

  As shown in FIG. 1, the anchor 4 of the ship 1 is connected to the tip of the anchor chain 5, and the anchor chain 5 is opened on the deck 2 of the ship 1 by the winder 19 on the deck 2 prior to operation. Winding up through the lifting port 3, the rod 4 is pulled up to the side surface 6 of the ship 1.

  Next, after anchoring the anchor chain 5 with the chain stopper 20, the anchor chain 5 is completely stopped using the anchor stopper 7 according to the present invention, and the anchor 4 is securely and safely held on the ship side surface 6. The anchor stopper 7 according to the present invention described above is supported on the deck 2 as follows.

  First, as shown in FIGS. 1, 3, and 4, the support base 10 is installed on the deck 2 of the ship 1. The support base 10 has an operation surface 9 to which a double nut 8 is fixed. Next, the screw rod 12 is screwed into the operation surface 9 through the double nut 8. A handle 11 is fixed to one end 13 of the screw rod 12 on the operation surface 9 side, and a chain 18 is connected to the other end 14.

  As shown in FIG. 2 and others, the chain 18 is provided with a locking piece 16 at the tip 17, and the tip of the locking piece 16 has a pawl 15 similar to a rake bent in a U-shape as shown in FIG. Preferably, two are formed.

  As shown in FIG. 1, the anchor stopper 7 of the present invention configured as described above was wound around the anchor chain 5 by the winder 19 installed on the deck 2 and connected to the tip as shown in FIG. Raise the anchor 4 to the side 6 of the ship 1.

Next, after anchoring the anchor chain 5 with the chain stopper 20, as shown in FIG.
The U-shaped pawl 15 of the locking piece 16 is hooked and locked to the anchor chain 5 wound up on the deck 2. FIG. 6A is a side view showing a state in which the pawl 15 is hooked on the anchor chain 5, and FIG. 6B is a plan view.

  Thereafter, the handle 11 is operated to pull the chain 18, and the anchor chain 5 is tensioned to hold the heel 4 securely and safely on the side surface 6. FIG. 3 is a side view of the state in which the pawl 15 of the locking piece 16 is hooked on the anchor chain 5. FIG. 4 shows the anchor chain 5 by operating the handle 11 after hooking the pawl 15 of the locking piece 16 on the anchor chain 5. FIG. As shown in FIG. 4, even if the screw rod 12 is pulled up and the anchor chain 5 is tensioned by operating the handle 11, the screw rod 12 may reversely rotate and return due to the action of the double nut 8. Does not happen.

  As described above, the anchor stopper of the present invention is designed so that the U-shaped pawl of the locking piece is pulled and locked, and then the handle is operated to pull the chain to tension the anchor chain. The work can be performed in a short time of about 30 seconds with the worker standing up, so that the work effort of the worker is reduced and the dredge is securely held on the side of the ship. It can contribute to the safe operation of the ship and is highly available in the marine field.
