Description

[Detailed description of the invention] The present invention relates to a method for automatically mooring a ship.

1 and 2 show typical conventional mooring methods.

That is, as shown in FIG. 1, the ship 50 has bollards 51, 52 at the bow and stern, and a pair of pips 54, 55 are provided on the quay 53.

As the ship 50 approaches the quay 53 as shown by the solid line in FIG. A person receives it and attaches it to the bit 54.

As a result, the ship 50 approaches the quay 53 while being further decelerated, and enters the state shown by the imaginary line in FIG. 1.

Here, a mooring cable 57 is attached to the bollard 52 on the stern side.
A crew member grabs the bit and moves to the quay 53 side, and this crew member attaches it to the bit 55, thereby mooring the vessel 50 as shown in FIG.

According to this, the bit 54 receives the mooring rope 56 on the bow side.
A worker on the quay/wall 53 side must be on standby to install the ship, and the work of this worker is dangerous, and furthermore, a worker of 1 Å or more is required on the ship 50. .

Therefore, the present invention provides an automatic mooring method for a ship that can omit the work of workers on the quay and on the ship.One embodiment of the method will be described below with reference to FIGS. 3 to 11.

As shown in FIGS. 3 to 5, a mooring device 46 is provided on the bow side of the ship 1 (in the illustrated example, the starboard side).

That is, a base plate 4 is attached to the upper deck 3, and a top plate 6 is attached above the base plate 4 via a plurality of supports 5.

A hook 2 is disposed between the plates 4 and 6, and is swingably attached between the plates 4 and 6 via a vertical shaft 7 disposed near the side.

This hook 2 has a locking portion 8 formed on the front side of its tip, and a recessed portion 9 formed on its rear end, and a cam roller 10 is attached above the recessed portion 9.

A deceleration motor 11 is mounted on the top plate 6, and a rotating shaft 12 passes through the space between the two plates 4 and 6.

A cam 13 located between both plates 4 and 6 is attached to this rotating shaft 12.

That is, the cam 13 is fan-shaped, and has a protrusion 14 that can fit into the recess 9 and a cam surface 15 that can come into contact with the cam roller 10 on its side surface.

Reference numeral 16 indicates a stopper for regulating the non-locking position of the hook 2.

As shown in FIGS. 6 to 9, a cylindrical post 18 is erected on the quay wall 17 side.

A vertical shaft 24 rotatable around a vertical axis 230 is provided between a top plate 19 attached to the upper end of the post 18 and a support plate 20 attached to the inside of the post 18 via upper and lower flanges 21 and 22. is installed.

A frame 2 surrounding the vertical axis 24 between the drawing boards 19 and 20
5 is arranged, and this frame body 25 has a horizontal pin 26 on the vertical axis 24.
210, and is configured to be able to swing around the horizontal axis 210.

A pair of front and rear penetration parts 28 and 29 are formed in the post 18, and a pair of arms 30 pass through these penetration parts 28 and 29.
．． 31 is fixed to the frame 25.

A pillar 32 is erected from the upper end of the vertical shaft 24, and a rope 33 for suspension reinforcement is stretched between the upper end of the pillar 32 and the tips of the arms 30, 31.

And a counterweight 3 is attached to the tip of one arm 30.
4 is attached, and a sheep 35 is attached to the other arm 31.

A pair of bits 36 and 37 are installed on the quay 17 side,
The mooring line 38 attached to the bit 36 on the side corresponding to the bow is hung on the sheave 35, and the mooring line 38 is attached to the free end of the mooring line 38.
9 is formed.

The upper surface forming the penetration part 28.degree. 29 is formed into an inclined surface 40.41 that guides the assumed movement of the arm 30.degree. 310, and when the other arm 31 is guided near the lowering limit, the arm 31 A stopper device 42 for locking is attached to the post 18 side.

This stopper device 42 operates its stopper rod 43 using, for example, an electromagnet, and is released after a timer has elapsed (the reason will be described later).

Before mooring the vessel 1, on the quay 17 side, due to the weight of the counterweight 34, the tension of the mooring rope 38, etc., the arm 31 is in a nearly horizontal state and is not attached to the quay 11, as shown by solid lines in FIGS. 6 to 10. The mooring line 38 is swung out to the sea side at a nearly right angle to the anchored part 39.
It is hanging down sufficiently due to the weight of.

On the other hand, in the ship 1 to be moored, the hook 2 is swung into a locking position as shown by solid lines in FIGS. 3 and 4, and this position is maintained by the cam roller 10 drawing in close contact with the cam surface 15. has been done.

In this state, as shown by the solid line in FIG. 10, the ship 1 is brought to the berth while being decelerated.

This docking is carried out in such a way that the locking portion 8 of the hook 2 is hooked on the mooring cable 38.

Then, the ship 1 moves with the hook 2 locked to the mooring line 38, and the locked part 39 of the mooring line 38 is attached to the locking part 8.
The ship 1 is stopped while applying tension to the mooring line 38 in a locked state.

At that time, the arm 31 is directed downward in the moving direction of the ship 1,
That is, it moves obliquely downward, resulting in the state shown by the imaginary lines in FIGS. 7 to 10.

In other words, while the mooring rope 38 becomes straight due to tension, the arm 31 only moves against the balance due to its own weight, and this movement is completely free. This does not place a large load on the post device including the arm 31.

At this time, the stopper device 42 is activated to lower the stopper rod 43 as shown by the imaginary line in FIG. 9 to prevent the arm 31 from returning.

In the state shown in the imaginary line in Figure 10, the bollard 44 on the stern side
A crew member grabbed the mooring line 45 attached to the quay 17.
By transferring to the side and attaching the bit 37 to the bit 37, the ship 1 can be moored as shown in FIG.

In order to leave the ship 1, a crew member first removes the mooring line 45 from the bit 37 and transfers to the ship 1.

Then, the deceleration motor 11 is operated to rotate the cam 13.

Then, since the cam surface 15 comes off the cam roller 10, the hook 2 swings from the state shown by the solid line in FIG. 4 to the state shown by the imaginary line in FIG. Missing the mark.

When the mooring line 38 is disengaged, the arms 30, 31, etc. try to return, but this is prevented by the stopper rod 43, which is in the operating position due to the operation of the timer.

Therefore, this occurs when the mooring line 38 is pulled up when the ship 1 has not left the shore sufficiently.

For example, damage to the vessel 1 caused by the mooring line 38 and personal injury on the deck can be prevented.

The timer is set to go off when the vessel 1 has left the shore sufficiently, and at this time the stopper rod 43 is raised, so that the arms 30, 31 and the mooring line 38 return to their original states.

On the ship 1 side, as shown in the imaginary line in Figure 4, 7 tsuku 2
is received by the stopper 16, and the deceleration motor 11 is stopped with the protrusion 14 pushed into the recess 9, thereby stopping the hook 2 from rattling.

Then, when moving to the berthing mentioned above, the deceleration motor 11
The relationship between the cam 13 and the hook 2 may be changed from the imaginary line in FIG. 4 to the solid line by slightly driving the cam 13 and the hook 2.

As described above, according to the present invention, a ship can be berthed and berthed only by the crew members, which eliminates the need for dangerous work by the workers at the quay, and at the same time, it is possible for the crew members on the ship to do the mooring work. can also be reduced.
