Description

[Detailed description of the invention] The present invention relates to an anchor hoisting device for a ship.

Conventionally, on large ships, pulling up the anchor is done using power, but on Type 4 ships, when pulling up the anchor once it has been lowered, it is necessary to manually pull up the anchor rope and raise the anchor. work is being done.

This required a great deal of effort and time. In this invention, an anchor lifting device for a ship can quickly and easily pull up an anchor by using the propulsion force generated by the ship's running and the buoyancy of the float body without requiring a power device for pulling up the anchor. We aim to provide the following.

Embodiments of the present invention will be described in detail below based on the drawings.

A is an anchor pulling device, B is a ship, C is an anchor, and D is an anchor rope.

Reference numeral 1 denotes a cylindrical body having a hollow portion S, which has a diameter sufficient to allow an anchor rope D to be inserted therein.

A locking body 2 pivotally attached to the cylindrical body 1 is located in the middle of the hollow portion S, and the locking body 2 locks on the circumferential surface of the anchor rope ○ inserted into the hollow portion S. In particular, the anchor rope D is configured to prevent sliding only when the anchor rope D attempts to slide in the direction of the anchor.

That is, a closing part 3 is provided in the middle of the cylindrical body 1,
A shaft support 4 is erected on the periphery of the entrance 3, a pivot 5 is installed on the coaxial support 4, and a locking body 2 is mounted on the pivot 5.
Moreover, the locking body 2 is formed in a substantially L-shape, and the tip of the locking body 2-1, which is the horizontal side portion of the substantially L-shape, is formed in a sawtooth shape 6, and the locking body 2 is formed in a substantially L-shape. The locking operation body 2-2, which is a vertical side portion of the letter shape, is connected to the float body 8 via a float string 7. Further, the locking body 2-1 of the locking body 2 is connected to the locking operation body 2-
2 moves toward the ship side of the cylindrical body 1, when the cylindrical body 1
The anchor rope D inside is locked with a mirror-toothed tip 6. 9
This is a spring biased at the upper end of the locking body 2 as necessary, and serves to supplementally bias the locking body 2-1 in the locking direction of the anchor rope D.

Reference numeral 10 denotes an auxiliary locking body provided in the hollow part S of the cylindrical body 1 at a position close to the anchor side as necessary, and is similar to the locking body 2-1 of the locking body 2, and is an anchor rope locking body. act.

11 are two split parts of the cylindrical body 1, and when the anchor lobe ○ is inserted into the hollow part S of the cylindrical body 1, the same two split parts 1
1 to Sekiguchi, insert the same rope D, and then insert the two-part part 1.
1 is occluded and fixed.

Reference numeral 12 denotes a locking device for the halved part 11, and 13 is a hinge. The halved part 11 can be opened and closed using the hinge 13 as a pivot, and the anchor rope D can be inserted into and removed from the cylindrical body 1. conduct.

In addition, the function of the locking body 2 can be better achieved by providing the pivot position of the sub-stop body 2 pivoted on the cylindrical body 1 at a position closer to the ship B side than the center of the cylindrical body 1. The reason for this is due to the correlation between the buoyancy of the float body 8 and the pulling force of the anchor rope D due to the weight of the anchor C, as will be described later. The embodiment of the present invention is constructed as described above, and its operation is as follows. That is, when pulling up the anchor C, the anchor rope D is inserted into the hollow part S of the cylindrical body 1 of the anchor lifting device A by the necessary means,
Together with the floating body 8 in which the same anchor raising device A is attached to the locking body 2,
Throw it into the sea. The anchor lifting device A thrown on the sea is held at one place on the sea by the float 8, and in this state, one end of the anchor rope ○ is fixed to the ship B and the ship B travels. Due to the propulsive force of the ship B, the anchor rope D is pulled in the ship's traveling direction while sliding through the hollow part S of the cylindrical body 1, and the cylindrical body 1 is pulled by the buoyancy of the float body 8 attached to the locking body 2. Because it is stationary at a certain point on the sea,
The anchor lobe ○ will pull up the anchor C via the cylinder 1 in the identified layer state, and furthermore, the direction in which the anchor rope D is pulled by the ship is determined by the locking body 2 in the hollow part S of the cylinder 1. Since 1 is the direction in which the anchor rope ○ is not locked, the anchor rope 0 slides inside the cylindrical body 1 without any hindrance and pulls up the anchor C near the cylindrical body 1.

To explain this state in more detail, when the anchor rope D is pulled by the propulsive force of the vessel B, the rope is pulled in the horizontal direction, so the cylindrical body 1 becomes almost horizontal, and the anchoring body 2
The locking operation main body 2-2 is pulled upward by the buoyant force of the float body 8 and becomes an upright state, so that the locking main body 2-1 is operated by sliding the anchor rope ○ on the ship side in the hollow part S in the cylindrical body 1. (See Figure 5).

As described above, if the ship stops pulling the anchor rope ○ at the same time as the anchor C is pulled up, the anchor C
Due to the weight of the cylindrical body 1, which is in a nearly horizontal state, stands vertically, and the locking body 2 is still maintained in an upright state due to the buoyancy of the float body 8.
Hold the anchor rope D in the hollow part S to make it locked,
The cylindrical body 1 is fixed to the anchor lobe D, and the cylindrical body 1
Since it is supported by the buoyancy of the float body 8, it prevents the anchor C from sinking (see Fig. 6).

In this state, if the anchor rope D is pulled manually from above the ship 8 and the floating anchor C is pulled up onto the ship B, the work of pulling the anchor is completed. According to this invention, the anchor is pulled up by the propulsion force of the ship, the anchor is raised to a certain depth, and the sliding of the anchor rope is stopped by the stop body in the cylindrical body, and the float The cylindrical body is integrally fixed to the anchor rope, preventing the anchor from sinking, and has the effect of allowing the anchor to be pulled up easily and in a short time using the ship's propulsion force. be.

Also, in particular, use a cylindrical body and anchor the cylindrical body.

It is used as a guide for the rope, and the locking body is pivoted in the middle of the cylindrical body near the ship side, so when the anchor is pulled up, the cylindrical body becomes horizontal horizontally, and the anchor is held up to a certain level. After pulling up the cylindrical body, the cylindrical body can be easily reversed in the vertical direction, and the anchor rope can be easily locked with the cylindrical body.
