Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for paying out mooring lines from a mooring machine on a ship.

Generally, as a ship becomes larger, the diameter of the mooring ropes installed also increases, but the maximum allowable diameter of mooring ropes that can be handled manually by shipboard workers is 38 to 40 mm for wire, and synthetic fiber rope. It is said to be about 70mm in the case of .

By the way, conventionally, when this mooring line was paid out to the ship's side, the mooring line was carried out manually to the mooring hardware on the ship's side while being paid out from the drum of the mooring machine.

However, large-diameter mooring lines are extremely heavy and must be carried over a distance of 30 to 40 meters for large ships, which requires a large amount of manpower and effort, and is the biggest obstacle in mooring operations. .

The present invention aims to solve these problems in mooring work, and aims to provide a method for letting out mooring lines that reduces the labor of workers by allowing the mooring lines to be paid out to the ship's side using power. The purpose is to provide equipment.

For this reason, the mooring line payout device of the present invention includes an auxiliary line detachably connected to the tip of the mooring line in order to pay out the mooring line from the mooring line main drum of the onboard mooring machine toward the ship side; An auxiliary rope auxiliary drum rotatably built into a mooring machine, and an auxiliary rope guide mechanism that guides the tip of the auxiliary rope wound around the auxiliary drum to the mooring rope of the main drum via the side of the ship. In order to further pull out the mooring rope that has been let out to the ship's side to the extent that it should be suspended along the ship's side shell, the auxiliary rope guide mechanism provides a mooring hardware for making the auxiliary rope run along the ship's side edge at the ship's side. It is characterized by being constructed with a vertical roller and a deck stand roller that is spaced apart from the vertical roller and provided closer to the ship's side.

Hereinafter, a mooring cable payout device as an embodiment of the present invention will be explained with reference to the drawings. Fig. 1 is a plan view thereof, Fig. 2 is a front view showing a part of its auxiliary cable guide mechanism, and Fig. 2 is a - arrow view of FIG. 2. FIG.

As shown in Fig. 1, a mooring line 4a is wound up and unwound to one side of the ship from a mooring line main drum 5 of a mooring machine 2 installed on the upper deck 1 of the hull. The cable 4a is guided to a quay or the like via a mooring hardware 3 serving as a closed-air leader on the ship's side.

Further, the mooring line 4b is unwound from the main drum 5 to the other ship side.

The mooring line 4a has a hook 11 that removably engages with an eye 10 at the tip thereof when the mooring line 4a is let out to the ship side.
The mooring rope 4b is pulled out by an auxiliary rope 9a with a handle, and the mooring rope 4b is similarly pulled out by an auxiliary rope 9b.

A main drum 5 is moored and unmoored to the rotational drive shaft of the mooring machine 2 via a clutch lever 7, and an auxiliary rope 9a
auxiliary drum 6a for use and auxiliary drum 6b for auxiliary cable 9b
are adapted to be engaged and disengaged via a clutch lever 8.

Note that the clutch lever 8 is connected to the auxiliary cable drum 6.
This clutch lever 8 is installed between the clutch levers a and 6b, and is provided with three operating positions.

That is, in addition to the operating position where one auxiliary drum 6a is fixed to the rotational drive shaft of the mooring machine 2, the neutral position where both auxiliary drums 6a and 6b are simultaneously removed from the rotational drive shaft of the mooring machine 2, and the other auxiliary drum 6b is moored. Three operating positions are provided, one being fixed to the rotary drive shaft of the machine 2.

As an auxiliary rope guide mechanism, deck stand rollers 12 and 13, vertical rollers 15a and horizontal An auxiliary rope guide hardware 15 (see FIGS. 2 and 3) consisting of a roller 15b is provided. In particular, the deck stand roller 12 is provided closer to the ship's side, and the auxiliary rope guide hardware 15 is provided on the mooring hardware 3 on the ship's side. As a result, this auxiliary cable guide mechanism has a guide path along the ship's side edge in a portion from the auxiliary cable guide hardware 15 to the deck stand roller 12.

And, in this part of the guide route along the ship's side,
The handrail 16 is disposed slightly inward compared to other parts so that the auxiliary cable 9a and the mooring cable 4a can be guided outside the ship's side.

In Figure 1, ○A indicates the mooring cable 4a or the auxiliary cable 9.
A shows the state in which the mooring cable 4a is attached to the guide hardware 15, and ○ and b show the state in which the mooring cable 4a is removed from the guide hardware 15.

In FIG. 1, in preparation for letting out the mooring line 4a, first the auxiliary line 9 is moved from the auxiliary drum 6a.
a is pulled out, and this auxiliary rope 9a passes through the deck stand roller 13 and the deck stand roller 12, and then passes through the vertical roller 1 of the guide hardware 15 shown in FIGS.
5a and the horizontal rollers 15b, further through the opening of the mooring hardware 3, via the upper part of the horizontal roller 14 on the ship, and guided to the vicinity of the main drum 5 of the mooring machine.

Therefore, a hook 11 provided at the tip of the auxiliary rope 9a
is connected to the eye 10 at the tip of the mooring line 4a.

Next, operate the clutch lever 7 to
The main drum 5 of the mooring machine 2 is removed from the rotary drive shaft of the mooring machine 2 so that it can rotate freely. In addition, by operating the clutch lever 8, the auxiliary drum 6a (the auxiliary rope 9a is wound downwardly) is fixed to the rotational drive shaft of the mooring machine 2, so that it rotates together with the rotational drive shaft of the mooring machine 2, The auxiliary drum 6b (the auxiliary rope 9b is wound upwardly) is removed from the rotational drive shaft of the mooring machine 2.

After completing the preparation work for feeding out the mooring line 4a in this way, the mooring machine 2 is operated and the mooring line 4a is
If you rotate a in the feeding direction, the auxiliary drum 6a
The auxiliary rope 9a is wound around, and the mooring rope 4a is pulled by the winding force, and the main drum 5 rotates so as to pay out the mooring rope 4a.

Initially, the auxiliary rope 9a and the mooring rope 4a are guided to pass through the course indicated by ○A in FIG.
When the connection between the eye 10 and the hook 11 of the auxiliary rope 9a comes close to the dock stand roller 12, the operation of the mooring machine 2 is stopped and the clutch lever 7 is operated to move the main drum 5 to the mooring machine 2. fixed to the rotating drive shaft.

Also, the clutch lever 8 is brought to the neutral position and the auxiliary drums 6a, 6b are removed from the rotary drive shaft of the mooring machine 2. Then, the eye 10 of the mooring line 4a is secured to the handrail 16 using a suitably small diameter fiber rope. In the same way, the mooring rope 4a is secured to the handrail 16 at a point slightly protruding from the ship side mooring hardware 3 toward the deck stand roller 12 side using an appropriate small-diameter fiber rope.

After performing the above operations, the mooring machine 2 is slightly operated to let out and loosen the mooring line 4a a little, and the mooring line 4a is brought to the outside of the vertical roller 15a of the guide hardware 15 by human power. That is, the mooring cable 4a is removed from the guide hardware 15.

Next, the eye 10 of the mooring rope 4a and the hook 11 of the auxiliary rope 9a are disconnected, and the small diameter fiber rope that ties the eye 10 and the mooring rope 4a to the handrail 16 is cut.

As a result, the mooring line 4a hangs down from the ship's side mooring hardware 3 outside the ship, but if the rotary drive shaft of the mooring machine 2 is rotated to the side where the mooring line 4a is fed out,
Due to the weight of the mooring line 4a hanging down from the ship side mooring hardware 3, the mooring line 4a can be continued to be let out.

If the deck stand roller 12 can be placed sufficiently away from the ship side mooring hardware 3, the mooring machine 2 can be operated in the direction of letting out the auxiliary rope 9a after removing the mooring rope 4a from the guide hardware 15. By doing so, the mooring line 4a can be gradually lowered along the ship's side shell surface, and the mooring line 4a can be lowered to a small boat from the land side that has approached the ship, and the eye 10 of the mooring line 4a can be lowered on this small boat. It is also possible to perform a mooring cable payout operation in which the mooring cable is disconnected from the hook 11 at the tip of the auxiliary cable. In this case, the work after removing the mooring rope 4a from the guide hardware 15 can be slightly simplified compared to the above case.

In this way, the work of letting out the mooring rope 4a is completed, but the auxiliary rope 9a is wound around the auxiliary drum 6a by appropriately operating the mooring machine 2.

When letting out the mooring line 4b to the opposite side,
If each member is arranged as shown in the figure on the opposite side, it can be extended by performing the same operation as described above.

As described in detail above, according to the mooring line payout device of the present invention, in order to pay out the mooring line from the mooring line main drum of the onboard mooring machine toward the ship side, the auxiliary mooring line is connected to the tip of the mooring line. an auxiliary rope for an auxiliary rope that is rotatably incorporated into the mooring machine, and an auxiliary rope that guides the tip of the auxiliary rope wound around the auxiliary drum to the mooring rope of the main drum via the side of the ship. The auxiliary rope guide mechanism guides the auxiliary rope along the ship's side edge at the ship's side in order to pull out the mooring rope that has been let out to the ship's side to a surplus that should be further suspended along the ship's side shell plating. It has an extremely simple configuration, consisting of a vertical roller with mooring hardware for mooring, and a docking stand roller installed away from the vertical roller and closer to the ship's side. Using the power of the machine, it becomes possible to perform the work efficiently, quickly, and safely.

In particular, in the device of the present invention, the auxiliary rope guide mechanism guides the auxiliary ropes at the ship's side portion to the ship's side edge in order to pull out the mooring rope that has been let out to the ship's side to a surplus that should be further suspended along the ship's side shell plating. The system is equipped with a vertical roller with mooring hardware attached to the mooring cable to allow the mooring line to line the ship, and a docking stand roller that is placed away from the vertical roller and closer to the ship's side. It becomes possible to hang the mooring line along the plate, and the weight of the mooring line suspended in this way has the advantage that the mooring line can be continued to be paid out efficiently.
