Description

[Detailed description of the invention] The present invention relates to a cable letting-out device, and its purpose is to omit the work of pulling out mooring cables and arranging them on the deck in advance (snake-down work) when a ship is berthed. It is also an object of the present invention to provide a cable letting-out device that can save labor in mooring work.

Therefore, in the present invention, a pair of drums around which an endless belt is wound are rotatably and horizontally supported in a cantilevered manner, and an arm is rotatably supported at a position above the belt, and the pair of drums is rotatably supported by an arm at a position above the belt. A roller capable of pressing and holding the rope between the belt and the belt is provided horizontally at an intermediate position, and a hydraulic motor for rotating the one drum and roller is built into the one drum and roller, respectively, and the arm is raised and lowered. The system is equipped with a hydraulic cylinder that presses the mooring line between the endless belt and the rollers at an intermediate position between the pair of drums to increase the contact area. Since it is driven by a hydraulic motor and is fed out, it can be fed out with a large force.Furthermore, the endless belt is supported cantilevered by a pair of drums, and the rollers can move up and down, making it suitable for use as an endless belt for mooring lines. It can be easily carried from the side between the rollers, and maintenance such as replacing the endless belt can be easily performed, and the entire device can be made compact and mooring work can be omitted. It is something.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 8.

Reference numeral 1 designates a pedestal provided on the side deck 2, and 3 and 4 designate a pair of front and rear drums that are cantilever-supported and rotatably projected horizontally from the pedestal 1 at positions corresponding to the fairlead 5.

That is, a T-shaped support 6 projects from the center of the pedestal 1, and one end of the front drum 3 closer to the fairlead 5 is supported via a hydraulic motor 7 built into the front drum 3. The other end shaft portion 8 is supported by the front end of the horizontal member 6a of the support body 6 via a bearing 9, and the rear drum 4, which is farther from the fairlead 5, is supported by the pedestal 1 and the horizontal member 6a of the support body 6. Bearings 11, 11' are mounted on the shaft 10 supported across the rear end.
Supported through.

Reference numeral 12 denotes an endless belt wound around the pair of drums 3 and 4, which is of a timing belt type.

Note that the size of the T-shaped support member 6 is the same as that of the pair of rollers 3 mentioned above.
, 4 and between the belt 12.

In addition, flanges 14 and 14' for preventing escape of the mooring line 13 are provided on both sides of the rear drum 4, and
These flanges 14, 14' are constructed in half for attachment of the belt 12.

Furthermore, since the rear drum 4 is used for tensioning the belt 12, a take-up device 15 is attached to one end of the shaft 10, and the other end support member 16 is provided with an elongated hole 17 so as to be movable in the tensioning front and back direction. and is attached to the frame 1 with bolts 18.

A roller 19 is rotatably supported by an inverted arm 20 at a position above the belt 12, and presses and holds the mooring line 13 between it and the belt 12 at an intermediate position between the pair of drums 3 and 4. The mooring line 13 is let out to the fairlead 5 side.

That is, one end of the roller 19 is connected to the horizontal portion 20a of the arm 20 via a hydraulic motor 21 built into the roller 19.
The other end shaft portion 22 is supported at the tip of the horizontal portion 20a of the arm 20 via a bearing 23.

Further, the roller 19 can move toward and away from the belt 12 in the vertical direction.

That is, the vertical portion 20b of the arm 20 supporting the roller 19
is externally fitted onto a vertical support 24 erected on the pedestal 1, and is movable up and down by a hydraulic cylinder 25 provided inside.

Note that 26 is a drum for winding up the Messenger rope connected to the other end shaft portion 8 of the front drum 3.

Next, the procedure for letting out the mooring line overboard will be explained.

In addition, in ships, as shown in Figures 7 and 8,
A pair of drums 3.4 includes a fairlead 5 and a mooring line drum 2.
It is placed on a straight line connecting 7.

First, with the roller 19 in the raised position (as shown by the imaginary line in FIG. 1), the hydraulic motor 7 built in the front drum 3 is driven to wind up the metsenger rope of the mooring line 13. At the same time, the mooring line 13 is guided onto the belt 12.

Next, the arm 20 is lowered by the hydraulic cylinder 25, and as shown in FIG.
The belt 12 is held under pressure between a roller 19 located between the rollers 19 and the belt 12.

Then, by operating the rollers 19 and the belt 12 in the directions of arrows A and B in FIG. 1 by the respective hydraulic motors 7 and 21, the mooring line 13 can be automatically let out overboard.

In the mooring state, the mooring line 13 is in tension at a position above the belt 12, but at this time the roller 19 is raised to the uppermost position to avoid it.

As described above, according to the cable payout device of the present invention, the cable can be automatically paid out, thereby saving labor in mooring work, and the device has the following advantages.

■ The rope is pressed between the endless belt and the roller at the middle position of the pair of drums to increase the contact area, and one drum and roller are driven by their own built-in pressing motors to let out the rope, which reduces the unwinding force of the rope. can be increased.

■ Since the pair of drums is cantilevered, maintenance such as belt replacement is easy.

■ Since the roller is supported by an arm that can be raised and lowered,
Retention and detachment of the chordae becomes easier.

■ Since the hydraulic motors that rotate the rollers and drums are built into each roller and drum, the entire device can be made compact.
