Description

[Detailed Description of the Invention] The present invention relates to a rigging device that can be advantageously adopted particularly for large ships.

On large ships, work involving large-diameter steel cables, fiber cables, etc. includes snake-down work, tug rope removal, and cable transport work to the side. These operations require a lot of manpower and are a major obstacle to reducing the number of crew members.

In order to solve the above problems, the present invention provides a support body rotatable around a vertical axis on the hull, a multiple link mechanism whose base end is rotatably connected to the support body, and A drive device is provided to bend and drive the link mechanism, a mounting base is rotatably disposed at the tip of the multiple link mechanism via a torque hinge, a motor is disposed on the mounting base, and the output of the motor is A spherical disk is attached to the shaft, a plurality of rods for winding the rope are protruded from the outer surface of the disk, and a hook for hooking a rope is provided at a suitable place on the outer circumference of the disk.For example, it is used for tugboats. When transferring the cable to a cable, the motor rotates the disc body and the cable let out from the winch is wound around the rod on the disc body, and then the support body is rotated and the multiple link mechanism operates. According to
By bringing the disc above the tug outside the ship's hull, and then turning the disc into a downward position using a torque hinge, the line wound around the rod can be dropped onto the tug, allowing the line to be transferred from the ship's hull to the tug. It can be done reliably. In addition, when pulling a cable from a tugboat onto a ship's hull, the disc body is placed above the tugboat in a position that is not facing downward, and the cable is wound around the rod of the disc body by rotating, and then the disc body is brought above the hull. This makes it possible to reliably pull the cable onto the hull.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 5. 1 is the hull, and 2 is a rope winding winch installed in the center of the hull. 3 is a double link, one end of which is a support 5 protruding from the upper deck 4.
is supported via a horizontal shaft 6. Further, the support body 5 is rotatable around a vertical axis 7. With this configuration, the double link 3 can rotate around the vertical axis 7 between its left and right sides, that is, between the center side and the ship's side of the hull 1. The proximal link 3A has a length such that its tip reaches slightly outside the ship's side when it is rotated toward the ship's side. In addition, when the base link 3A rotates toward the center of the hull 1, the intermediate part is attached to the upper deck 4.
It comes to be supported by a stand 8 installed at. The proximal link 3A and the distal link 3B are connected via a pin 9 parallel to the horizontal axis 6. 10 is an oil motor, 11 is a torque hinge, and these are attached to a mounting base 12. In this case, the output shaft 10A of the oil motor 10 and the rotating shaft 11A of the torque hinge 11 are set to be perpendicular to each other. And the rotation axis 1 of the torque hinge 11
1A is attached to the tip of the double link 3 in a direction orthogonal to the tip link 3B and horizontally. Reference numeral 13 denotes a connecting fitting between the tip link 3B and the torque hinge rotating side 11A. Reference numeral 14 denotes a spherical disc body, the center of which is fixed to the oil motor output shaft 10A. A plurality of (three in the illustrated example) rods 15 are provided protruding from the outer surface of the disc body 14. That is, these rods 15 are provided at equal angle intervals on an imaginary circumference concentric with the disc body 14, and at least one of them is a tapered rod. In the illustrated example, all the rods 15 are configured as tapered rods. Reference numeral 16 denotes a hook for hanging an index, which is provided on the disc body 14. 17A and 17B are cylinder devices, which are respectively interposed between the support 5 and the proximal link 3A and between the proximal link 3A and the distal link 3B. Therefore, the proximal link 3A is caused to swing around the horizontal axis 6 by the movement of one cylinder device 17A into and out, and the tip link 3B becomes the proximal link by the movement of the other cylinder device 17B into and out. It is made to swing around pin 9 with respect to 3A. It is assumed that the tip link 3B has a length corresponding to the distance from the top of the upper deck 4 to the sea surface 18. 19 is a tugboat.

In the above, when handling the cable 20 wound around the winch 2, the cylinder devices 17A, 17
While adjusting the amount of protrusion and retraction of B, the support body 5 is rotated around the vertical axis 7, and the disc body 14 is moved to the winch 2.
The disk body 14 is also swung through the torque hinge 11 to take an upward position (FIG. 1). From this state, one end of the cable 20 is locked to one of the rods 15, and then the oil motor 10 is operated to rotate the disc body 14 and wind the cable 20 around the plurality of rods 15. Next, the support body 5 and the double link 3 are rotated around the vertical axis 7, and the cylinder devices 17A and 17B are controlled to move in and out, and the cable 20 is pulled out from the winch 2 as shown in FIGS. 2 and 3. While being fed out, the disc body 14 is moved to the sea surface 18 and near the cable insertion place of the tugboat 19 or the like. Next, the disk body 14 is swung as shown by the arrow in FIG. 3 via the torque hinge 1 to take a downward position. When the disc body 14 is placed in a downward position, the cable 20 easily separates from the rod 15 and falls because the rod 15 around which the cable 20 is wound is configured as a tapered rod.

Cable 20 from sea surface 18 or tugboat 19 etc.
When lifting the cable onto the hull 1, the cable 20 is held in place by the hook 16 attached to the disc body 14 and then pulled up. In this case, rod 1
The cable 20 may be wound around the rope 5. When the rigging device is not in use, as shown in the imaginary line in Figure 2, the base end link 3A is supported on the stand 8, the double link 3 is bent, and it is housed on the hull 1 in the retracted position. put.

As is clear from the above explanation, according to the present invention, after the cable is wound around the rod on the disc body,
By simply bringing the disc onto the tugboat and rotating the disc downward using the torque hinge, a predetermined length of rope can be dropped onto the tugboat, ensuring reliable and easy delivery of the rope to the tugboat. On the other hand, when pulling a rope from a tugboat onto a ship's hull, the rope is wound around a disc body directly above the tugboat, and then the disc body is brought over the ship's hull, making it possible to pull the cable up reliably and easily. This has a great effect on reducing the number of crew members required, and also eliminates the dangerous work of having tugboat crews grab and take in the ropes while at sea, which would otherwise be required if the ropes were simply hung from the ship's hull. It can be resolved.
