Description
SPECIFICATION
Apparatus for veering a mooring rope
Field of the invention
The present invention relates to an apparatus for hauling in and veering out a mooring rope used for mooring a ship to a wharf, without relying upon human labor.
Background ofthe invention
It is the conventional practice to provide a winch 2 for hauling in and veering out a mooring rope for mooring a ship to a wharf on the upper deck 1 of the ship at the width center thereof as shown in Figure 1.
The winch 2 comprises a drum 3 of which the axis of rotation is arranged in parallel with the longitudinal direction of the ship, and a driving means 4 for rotating the drum 3.
In the above-mentioned winch 2, the ship is moored to the wharf7 as shown in Figure 1. More specifically, a mooring rope 5 hauled in onto the drum 3 of the winch 2 is manually veered out from the drum 3 until the leading end of the mooring rope 5 reaches the wharf 7 through a chock 6, and the leading end of the mooring rope 5 is secured to a bitt 8 fixed onto the wharf 7, thereby mooring the ship to the wharf 7. When departing from the wharf 7, on the other hand, mooring of the ship is released by taking the leading end of the mooring rope 5 offthe bitt 8 and hauling in the mooring rope 5 onto the drum 3 through actuation of the winch 2. In order to ensure that the mooring rope 5 is orderly hauled in onto the drum 3, the mooring rope 5 is manually pulled in the direction opposite to the hauling direction as shown in Figure 2.
However, the above-mentioned practice of veering out and hauling in the mooring rope 5 by means of the winch 2 involves the following problems: since the mooring rope 5 must be manually pulled for veering out and hauling in the mooring rope 5, this operation requires much labor with a very low operating efficiency. In addition, a mooring rope 5 made of steel often causes injury of operators' hands. Furthermore, when the upper deck 1 is wet with water such as rain water, operators are subject to slipping accident.
Under such circumstances, there is a demand for the development of an apparatus which permits safe and efficient veering and hauling of a mooring rope used for mooring a ship to a wharf without relying upon human labor, but such an apparatus has not as yet been proposed.
Summary ofthe invention
An object of the present invention is therefore to provide an apparatus for veering a mooring rope, which permits safe and efficient veering and hauling ofthe mooring rope without relying upon human labor.
In accordance with one of the features of the present invention, there is provided an apparatus for veering a mooring rope, which comprises:
a winch, provided on the upper deck of a ship at the width center thereof, for hauling in and veering out a mooring rope, said winch comprising a drum, of which the axis of rotation is arranged in parallel with the longitudinal direction of said ship, for hauling in and veering out said mooring rope, and a driving means for rotating said drum;
characterized by further comprising:
a rail (9) laid on said upper deck (1) of said ship across the width of said ship from one broadside to the other broadside, said rail (9) being laid in parallel with the width direction of said ship and passing below said drum (3); and
a rope feeder (10, 10') capable of travelling on said rail (9), said rope feeder (10,10') comprising:
a carriage (11) having wheels (12) rolling along said rail (9);
a first drive (13), connected to at least one of said wheels (12), for rolling said at least one of said wheels (12) to travel said carriage (11) along said rail (9) in the width direction of said ship;
a pair of pinch rolls (14,14') having axes of rotation arranged in parallel with each other, provided on said carriage (11), for gripping said mooring rope (5) and veering out same from said drum (3) of said winch (2);
a second drive (15, 15'), connected to said pair of pinch rolls (14,14'), for rotating said pair of pinch rolls (14, 14') in the directions opposite to each other; and
a reversing mechanism (16, 16'), connected to said pair of pinch rolls (14, 14'), for reversing the relative position of said pair of pinch rolls (14,14') to reverse the veering direction of the leading end of said mooring rope (5) gripped by said pair of pinch rolls (14,14').

Detailed description ofpreferred embodiments
From the above-mentioned point of view, we carried out extensive studies to develop an apparatus for veering a mooring rope, which permits safe and efficient veering and hauling of the mooring rope without relying upon human labor. As a result, we obtained a finding that the mooring rope can be veered out and hauled in without relying upon human labor by providing on the upper deck of a ship a pair of pinch rolls capable of travelling in the width direction of the ship, and veering out the mooring rope hauled in onto the drum of a winch provided on the upper deck of the ship by means of the pair of pinch rolls.
The present invention was made on the basis of the above-mentioned finding. The apparatus of the present invention is described below with reference to the drawings.
Figure 3 is a partially cutaway perspective view illustrating the apparatus of the present invention,
Figure 4 is a sectional view illustrating a first embodiment of the rope feeder of the apparatus of the present invention, and Figure 5 is a sectional view of Figure 4 cut along the line A-A. As shown in
Figures 3 to 5, a winch 2 for hauling in and veering out a mooring rope 5 is provided on the upper deck 1 of a ship at the width center thereof. The winch 2 comprises a drum 3, of which the axis of rotation is arranged in parallel with the longitudinal direction of the ship, for hauling in and veering out the mooring rope 5, and a driving means 4 for rotating the drum 3.
A rail 9, on which a rope feeder described later travels, is laid on the upper deck 1 of the ship across the width of the ship from one broadside to the other broadside. The rail 9 is laid in parallel with the width direction of the ship and passes below the drum 3.
A rope feeder 10 capable of travelling on the rail 9 comprises a carriage 11 having wheels 12 rolling along the rail 9; a first drive 13, connected to at least one of the wheels 12, for rolling the at least one of the wheels 12 to travel the carriage 11 along the rail 9 in the width direction of the ship; a pair of pinch rolls 14 having axes of rotation arranged in parallel with each other, provided on the carriage 11, for gripping the mooring rope 5 and veering out same from the drum 3 of the winch 2; a second drive 15, connected to the pair of pinch rolls 14, for rotating the pair of pinch rolls 14 in the directions opposite to each other; and a reversing mechanism 16, connected to the pair of pinch rolls 14, for reversing the relative position of the pair of pinch rolls 14 to reverse the veering direction of the leading end of the mooring rope 5 gripped by the pair of pinch rolls 14.
The axes of rotation of the pair of pinch rolls 14 of the rope feeder 10 are arranged one above the other and in parallel with the longitudinal direction of the ship, and the pair of pinch rolls 14 are fitted between a pair of bearings 1 7A and 17B vertically fixed on the carriage 11.
The second drive 15 of the rope feeder 10 comprises bevel gears 23 fitted to one-side ends of the pair of pinch rolls 14, a gear box 22 for housing the bevel gears 23, and a motor 24, fitted to the gear box 22, for driving the bevel gears 23. The gear box 22 is rotatably fitted to the bearing 17B via a horizontal rotating shaft 21 B. Therefore, by actuating the motor 24, the pair of pinch rolls 14 rotate in the directions opposite to each other, whereby the mooring rope 5 gripped by the pair of pinch rolls 14 is veered out from the drum 3 of the winch 2.
The reversing mechanism 16 of the rope feeder 10 comprises a vertical worm gear 18 fitted to the other ends of the pair of pinch rolls 14, a worm 19 engaging with the worm gear 18, and a third drive 20 for driving the worm 19. The worm 18 is rotatably fitted to the other bearing 1 7A via a horizontal rotating shaft 21A. Therefore, by actuating the third drive 20, the relative position of the pair of pinch rolls 14 is reversed upside down while gripping the leading end of the mooring rope 5, whereby the veering direction of the leading end of the mooring rope 5 is reversed.
According to the above-mentioned apparatus of the present invention, the mooring rope 5 hauled in onto the drum 3 of the winch 2 is veered out as follows: when the ship arrives at the wharf, the first drive 13 of the rope feeder 10 is actuated to travel the rope feeder 10 along the rail 9 from the housing position thereof below the drum 3 of the winch 2 to the broadside of the ship on the side of the wharf. As a result, the mooring rope 5 hauled in onto the drum 3 of the winch 2 is veered out to the broadside of the ship while the leading end of the rope is gripped by the pair of pinch rolls 14 of the rope feeder 10.If the veering direction of the leading end of the mooring rope 5 is not directed toward the wharf, the third drive 20 of the reversing mechanism 16 of the rope feeder 10 is actuated to drive the worm 19 and the worm gear 18to reverse the relative position of the pair of pinch rolls 14 upside down while gripping the leading end of the mooring rope 5, whereby the veering direction of the leading end of the mooring rope 5 is reversed toward the wharf. Then, by actuating the second drive 15 of the rope feeder 10 to rotate the pair of pinch rolls 14, the mooring rope 5 is veered out from the drum 3 of the winch 2 until the leading end of the mooring rope 5 reaches the bitt on the wharf through a chock 6A on that side.
On the other hand, the mooring rope 5 veered out from the drum 3 of the winch 2 is hauled in onto the drum 3 of the winch 2 by actuating the driving means 4 of the winch 2. In this operation, the motor 24 of the second drive 15 of the rope feeder 10 is forcedly rotated by the mooring rope 5 in the hauling direction via the pair of pinch rolls 14 and the bevel gears 23 of the rope feeder 10. Tension is thus imparted to the mooring rope 5 between the pair of pinch rolls 14 and the drum 3 of the winch 2. As a result, the mooring rope 5 is orderly hauled in onto the drum 3 of the winch 2. Tension may be imparted to the mooring rope 5 between the pair of pinch rolls 14 and the drum 3 of the winch 2 also by imparting a torque in the direction opposite to the hauling direction to the pair of pinch rolls 14 by means of the motor 24 of the second drive 15. After the mooring rope 5 is thus hauled in onto the drum 3 of the winch 2 until the leading end of the mooring rope 5 is gripped by the pair of pinch rolls 14, the rope feeder 10 is travelled back to the above-mentioned housing position thereof.
Now, a second embodiment of the rope feeder of the apparatus of the present invention is described with reference to the drawing.
Figure 6 is a sectional view illustrating the second embodiment of the rope feeder of the apparatus of the present invention. As shown in Figure 6, a rope feeder 10' capable of travelling on a rail 9 comprises a carriage 11 having wheels 12 rolling along the rail 9; a first drive 13, connected to at least one of the wheels 12, for rolling the at least one of the wheels 12 to travel the carriage 11 along the rail 9 in the width direction of the ship; a pair of pinch rolls 14' having axes of rotation arranged in parallel with each other, provided on the carriage 11, for gripping the mooring rope 5 and veering out same from the drum 3 of the winch 2; a second drive 15', connected to the pair of pinch rolls 14', for rotating the pair of pinch rolls 14' in the directions opposite to each other; and a reversing mechanism 16', connected to the pair of pinch rolls 14', for reversing the relative position of the pair of pinch rolls 14' to reverse the veering direction of the leading end of the mooring rope 5 gripped by the pair of pinch rolls 14'.
The axes of rotation of the pair of pinch rolls 14' of the rope feeder 10' are arranged at right angles to the upper deck 1 of the ship and in series along the longitudinal direction of the ship. The pair of pinch rolls 14' are fitted onto a gear box described later.
The second drive 15' of the rope feeder 10' comprises bevel gears 23' fitted to the lower ends of the pair of pinch rolls 14', a gear box 22' for housing the bevel gears 23', and a motor 24', fitted to the gear box 22', for driving the bevel gears 23'. The gear box 22' is rotatably fitted onto the carriage 11 with a vertical rotating shaft 25 as the center.
Therefore, by actuating the motor 24', the pair of pinch rolls 14' rotate in the directions opposite to each other, whereby the mooring rope 5 gripped by the pair of pinch rolls 14' is veered out from the drum 3 of the winch 2.
The reversing mechanism 16' of the rope feeder 10' comprises a horizontal worm gear 18' fixed to the outer peripheral surface of the gear box 22' of the second drive 15', a worm 19' engaging with the worm gear 18', and a third drive 20' for driving the worm 19'. Therefore, by actuating the third drive 20', the relative position of the pair of pinch rolls 14' is reversed with the front side back relative to the longitudinal direction of the ship, while gripping the leading end of the mooring rope 5, whereby the veering direction of the leading end of the mooring rope 5 is reversed.
According to the above-mentioned second embodiment of the rope feeder of the apparatus of the present invention, the mooring rope 5 is veered out from the drum 3 of the winch 2 and hauled in onto the drum 3 of the winch 2 in the same manner as in the first embodiment of the rope feeder of the apparatus of the present invention except that the relative positon of the pair of pinch rolls 14' is reversed with the front side back relative to the longitudinal direction of the ship.
The winch 2 and the rope feeder 10,10' in the apparatus of the present invention described above may also be actuated by a controller, apart from the manual operation.
Figure 7 is a block diagram illustrating a controller of the apparatus of the present invention, for actuating the winch 2 and the rope feeder 10, 10'. As shown in Figure. 7, the controller 26 comprises a detecting means 27, a memory 28, a rope feed length detector 29 for detecting a length of the mooring rope 5 veered out from the drum 3 of the winch 2, a rope tension detector 30 for detecting tension of the mooring rope 5 between the pair of pinch rolls 14,
14' and the drum 3 of the winch 2, a computer 31, and a programmable sequencer 32 (hereinafter simply referred to as the "sequencer").
The detecting means 27 comprises a ship position detector 33, a draft detector 34 and a water depth detector 35. The detecting means 27 detects a ship position, a draft and a water depth, as variable data among data necessary for calculating a length of the mooring rope 5 to be veered out from the drum 3 of the winch 2, and transmits detection signals corresponding to the variable data. The detection signals from the detecting means 27 may be either entered into the computer 31 by means of a keyboard 36 connected to a display 37 or automatically entered into the computer 31.
The memory 28 previously stores a distance from the upper deck 1 of the ship to the bottom thereof, a distance from the drum 3 of the winch 2 to the broadside of the ship, a width of the ship and a distance from the water bottom to a wharf, as non-variable data among data necessary for calculating a length of the mooring rope 5 to be veered out from the drum 3 of the winch 2, and transmits signals corresponding to the non-variable data.
The computer 31 calculates a length of the mooring rope 5 to be veered out from the drum 3 of the winch 2 on the basis of the signals from the detecting means 27 and the memory 28. More specificaliy, the computer 31 calculates the length (L) of the mooring rope 5 to be veered out from the drum 3 of the winch 2 in accordance with the following equation, on the basis of the detection signal corresponding to the draft (d) from the draft detector 34, the detection signal corresponding to the water depth (i) from the water depth detector 35, the signal corresponding to the distance (D) from the upper deck 1 of the ship to the ship bottom, sent from the memory 28, the signal corresponding to the distance (f2) from the drum 3 of the winch 2 to the broadside of the ship, sent from the memory 28, the signal corresponding to the height (h) from the water bottom to the wharf, sent from the memory 28, and the signal corresponding to the loosening length (f2) of the mooring rope 5, sent from the memory 28: L = D - d - (h - i) + i e In addition, the computer 31 transmits a start signal for actuating the winch 2 and the rope feeder 10,10'.
The sequencer 32 transmits, in accordance with the start signal from the computer 31, respective actuation signals to the driving means 4 of the winch 2, the first drive 13 and the second drive 15,15' of the rope feeder 10,10', and the third drive 20,20' of the reversing mechanism 16,16' of the rope feeder 10,10'.
More particularly, when veering out the mooring rope 5 from the drum 3 of the winch 2, the sequencer 32 transmits an actuation signal to the third drive 20,20' of the reversing mechanism 16,16' of the rope feeder 10,10' in accordance with the start signal from the computer 31 to reverse the relative position of the pair of pinch rolls 14,14' of the rope feeder 10,10' so that the veering direction of the leading end of the mooring rope 5 gripped by the pair of pinch rolls 14,14' is directed toward the wharf. Then, the sequencer 32 transmits an actuation signal to the first drive 13 of the rope feeder 10,10' to travel the rope feeder 10,10' from the housing position thereof below the drum 3 of the winch 2 to the broadside of the ship on the side of the wharf.Then, the sequencer 32 transmits an actuation signal to the second drive 15,15' of the rope feeder 10,10' to veer out the mooring rope 5 from the drum 3 of the winch 2 through the rotation of the pair of pinch rolls 14,14'. Then, when the length of the mooring rope 5 veered out from the drum 3 as detected by the rope feed length detector 29 of the detecting means 27 matches with the length (L) of the mooring rope 5 to be veered out from the drum 3 as calculated by the computer 31, the sequencer 32 transmits a stop signal to the second drive 15,15' to stop veering of the mooring rope 5 through stoppage of the rotation of the pair of pinch rolls 14,14'.
On the other hand, when hauling in the mooring rope 5 onto the drum 3 of the winch 2, the sequencer 32 transmits an actuation signal to the driving means 4 of the winch 2 in accordance with the start signal from the computer 31, to haul in the mooring rope 5 onto the drum 3 through the rotation thereof. Then, when tension of the mooring rope 5 between the pair of pinch rolls 14,14' and the drum 3 as detected by the rope tension detector 30 exceeds a prescribed value, the sequencer 32 transmits a stop signal to the driving means 4 of the winch 2 to stop hauling of the mooring rope 5 through stoppage of the rotation of the drum 3. Then, the sequencer 32 transmits an actuation signal to the first drive 13 of the rope feeder 10,10' to travel the rope feeder 10,10' back to the above-mentioned housing position thereof.
Display means such as lamps for visually monitoring the status of actuation of the winch 2 and the rope feeder 10,10' by the sequencer 32 are fitted on an operating panel 38. In addition to these display means, the operating panel 38 is equipped with switches for actuating the winch 2 and the rope feeder 10,10'.
When manually operating the above-mentioned controller 26, respective detection signals transmitted from the ship position detector 33, the draft detector 34 and the water depth detector 35 are manually entered into the computer 31 through the keyboard 36.
When automatically operating the controller 26, respective detection signals transmitted from the ship position detector 33, the draft detector 34 and the water depth detector 35 are directly and automatically entered into the computer 31 without operating the keyboard 36. As a result, the winch 2 and the rope feeder 10,10' are all automatically actuated.
According to the apparatus of the present invention, as described above in detail, it is possible to safely and efficiently veer out and haul in the mooring rope, and it is also possible to orderly haul in the mooring rope onto the drum of the winch, since tension is imparted to the mooring rope between the pair of pinch rolls of the rope feeder and the drum of the winch when hauling in the mooring ropes, thus providing industrially useful effects.
