Abstract

PURPOSE:To enable a mooring line to be automatically guided in its taking out operation by securing a hook, which makes three dimensional movement as required, with a pair of right and left hard rollers arranged on the tip of a jib which is rotatively and flexibly installed on the upper deck. CONSTITUTION:A horizontal frame 6 is secured on the tip of a jib A and B which is rotatively installed on a post 2 standing on the upper deck 1, and moves flexibly in the vertical plane. And a pair of right and left hard rollers 12, which are drivably secured as required, is arranged at the tip of the horizontal frame in such a way that the rollers are energized so as to be pushed each other. In addition, a hook 7 is arranged with a parallel link mechanism which enables the hook to move up and down, swing freely, and travel horizontally as required. This configuration enables human works involved in taking a mooring line out to be automated by swinging up and down the terminal eye-splice R of the mooring line, which is engaged with the hook 7, accompanied with its horizontal movement toward the roller 12.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a mooring line guiding device.

[Conventional technology]

Among the mooring work on a ship, handling the mooring line when guiding it from the mooring winch on the deck to the mooring bit on land via the mooring line guide is a very labor-intensive task, but it is not as easy as conventional methods. Most of the time this is done by hand by the crew, and in particular, passing the mooring line through a mooring line guide that has a closed structure requires a considerable amount of labor as it has to be done manually.

[Problem that the invention seeks to solve]

The present invention was proposed in view of the above circumstances, and an object of the present invention is to provide a mooring line guiding device that reduces conventional heavy labor and saves labor and manpower.

[Failure to solve the problem]

To this end, the present invention provides a jib that is rotatably attached to a post established on the upper deck and is capable of bending and extending in a vertical plane, and a jib that is attached to the tip of the jib and that allows the jib to remain horizontal despite the bending and extension of the jib. A horizontal frame is attached to the tip of the horizontal frame and when elastically biased in the direction of pushing each other, both rotate in opposite directions to send out the mooring line held between them. Or, if it has a pair of retractable left and right vertical rollers, a base end pivoted to the rear end of the horizontal frame, and a hook at the tip for hooking a mooring line, it is supported so as to be able to be raised up and down in a vertical plane. The hook bar member is supported so as to be movable in the horizontal direction along the horizontal frame, and the hook bar member is movable in the horizontal direction by elastically pushing open the pair of left and right vertical rollers at the tip.

[For production]

With such a configuration, it is possible to obtain a mooring line guiding device that saves labor and manpower.

When the horizontal frame 6. The hook link 7 cooperates with the long hydraulic cylinder 8 to form a parallelogram, and the upper end 9 of the link 9 is loosely inscribed in the circular hole forming the left end 10 of the horizontal guide groove 10 by a pin with a rectangular cross section. The pin is made thick enough to be able to move along the horizontal guide groove 10.

4 each indicates the rope end or eye splice;
R1 is the state where the rope is hooked on hook link 7,
R2 is in a state where hook link 7 and ＼ are both pulled up, R
3 shows the state in which both the hook link 7 and \ have passed between the rollers, and R4 shows the state in which the hook links 7 and \ have been fed outboard by the rollers 12 and 12.

In such a construction, jib I, n, column 5,
The long hydraulic cylinder 8, the short hydraulic cylinder 11, and the drive source 17 can be remotely controlled.

First, as shown in Figs. 2 and 3, by operating the post rotation part 2a, the jibs 1 and 2 are directed toward the eye splices of the mooring line, and by operating the hydraulic cylinders 3d and 4d, the jibs I and 2 are turned. After bending and stretching, moving the cable grip horizontally and vertically, and catching the eye splice at the end of the cable with the tip of the hook link 7 (see R1 in Figure 2), the rod of the short hydraulic cylinder 11 is retracted. Long hydraulic cylinder-8
The hook link 7, which together forms a parallelogram, is moved to the dashed-dotted line position 7' shown in FIG. 6 (see FIG. 3 R2),
Furthermore, by moving the rod of the long hydraulic cylinder 8, both the hook links 7 and 5 and the link 9 connected thereto slide on the horizontal guide groove 10 at their upper ends 9 while maintaining a horizontal position. Then, the hook link 7 moves to the position indicated by the two-dot chain line 7 (see R5 in the figure).

At this time, the pair of rollers 12 and 12 are pushed by the tip of the hook link 7 and elastically open to the left and right, as shown by the chain line arrows in FIG. 4, thereby allowing the hook link 7 and the eye splice to pass through. Then, the hook link 7 is at the two-dot chain line position 7.
When the eye splice reaches the position shown in FIG. It will be released.

Therefore, if the cable guide CC is of a closed structure such as a closed chock, when the hook link is in the position 7, it is connected to the jib 1, as shown in FIG. After driving the jib and column 5 to pass through the closed chock CC, driving the rollers 12 and 12 will cause the rope to be let out overboard through the cable guy FCC as shown in Figure 6. (See R4).

At that time, the eye splice at the end of the rope is 12.12
When the hook link is returned to position 7', the rollers 12 and 12, which are open on the left and right sides, will elastically close, so the rope can be clamped and rotated further, as shown in Figure 6. As if to do so, the rope was let out further overboard.

In this way, when the appropriate amount of the rope end is let out overboard,
After moving the rope grip part to a position away from the mooring line guide cc, and moving the hook link to position 7'', the rollers 12° 12 open left and right and the rope falls from the lower end of the roller.

According to such a structure, the jib ■ and the jib ■ can be rotated and bent together with the post rotation part, so the hook link can move in three dimensions, and the mooring of ship parts and dissections is possible. Even in a place where a large number of machines and paired cable guides are installed, the hook can be quickly moved to the desired location, and each prime number cutting operation can be performed with one unit of the present invention.

In addition, it is easy to move the rope from inside the ship to the side.
Whether the rope end is on the mooring aircraft or on deck, it is easily accessible and the horizontal frame 6 is connected to the jibs I and H.
Because it forms a parallelogram, it can always remain horizontal and can be turned by the column 5, so that the side and the mooring line guide installed there are on a horizontal plane with respect to the jib. No matter what angle you are in, you can take the position that is easiest for you to work in.

Furthermore, when the p-hook link 7 is kept in a horizontal position by the hydraulic cylinder, it moves in an arc while trying to pull up the rope end R, which makes it easy to catch it and prevents it from coming off during the mud operation.

By passing the tip of the hook link 7 between the rollers 12 and 12, the distance between them is widened, so that it is possible to pinch even rigid bulges such as wire rope eye splices. After the eye splice has passed, the distance between the rollers 12 and 12 □ will automatically grab and feed the narrow rope, and after the rope is let out overboard, the distance between the rollers 12 and 12 will be adjusted by the hook link 7. It is also possible to unfold and release the rope.

In this way, with this device, the series of operations up to sending the end of the rope on the mooring aircraft or on the deck overboard can be completed 100% by remote control, which was previously done manually. Most of the work will be automated, which will greatly contribute to freeing seafarers from heavy labor and saving labor.
4゜[Effects of the Invention] In short, according to the present invention, there is provided a jib which is attached to a post established on an upper deck in a pivot direction and is capable of bending and extending in a vertical plane; A horizontal frame that moves horizontally in parallel despite the bending and stretching of A pair of left and right vertical rollers for sending out and/or retracting the mooring line to be held;
The base end is pivotally attached to the rear end of the horizontal frame, the tip has a hook for hooking a mooring line, and it is supported so that it can be raised and lowered in a vertical plane.
Labor saving is achieved by including a hook rod member which is supported so as to be movable in the horizontal direction along the horizontal frame and whose tip can elastically push open the pair of left and right vertical rollers to move the rollers in the horizontal direction. The present invention is industrially extremely useful because it provides a mooring line guiding device that saves labor.
