Description

[Detailed Description of the Invention] The present invention relates to a rope locking and releasing device for locking mooring lines used for towing or mooring large ships, for example.

When passing a mooring line from a small tug board to a large ship, there is a considerable difference in height between the tugboat and the large ship, and the mooring line is quite heavy, so the force due to its own weight acts on the mooring line. For this reason, it is very difficult to lock and release the mooring line. Conventionally, when mooring, the mooring line was pulled up to the side of a large ship a considerable amount of time before the mooring line was anchored, and when releasing, the weight of the mooring line acts on the anchoring part. In order to prevent this from happening, mooring lines are temporarily restrained onboard large ships, and there was a need for a device that can easily and reliably lock and release mooring lines.

In order to solve the above problems, the present invention aims to provide a rope locking and releasing device that does not require pulling up the mooring line excessively when mooring and does not require temporarily holding the mooring line when disconnecting. .

In order to achieve the above object, the present invention provides a pair of left and right swinging frames between the cable guide member and the locking bollard, which can be raised up and down with the locking bollard side as a fulcrum, and these swinging frames are A pressing arm is provided between the distal ends of the frames, and a detachment arm is provided between the intermediate portions, and these arms and both swing frames form a cable insertion space, and the cable insertion space of the detachment arm and the detachment arm are formed. A cable guide plate is attached to the opposite position, a cable corner guide is attached to the cable insertion space side of the connection corner between the detachment arm and the swing frame, and the detachment arm is connected to the swing frame. It is constructed so that it is located above the locking bollard when it is erected, and is further provided with a presser support part that faces the pressing arm when the swing frame is laid down sideways. The mooring line that has been pulled up so that its locking part is located on the mooring bollard is temporarily fixed by the pressing arm and presser support part of the swing frame to prevent it from being pulled back by its own weight, and then it is attached to the mooring bollard. When detaching, the mooring line can be detached by the detachment arm of the pivot frame flipping up the mooring line from the mooring bollard as the pivot frame stands up and swings. and can be easily and reliably removed.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

Reference numeral 1 denotes a bed provided on the deck 2 near the side and in a position corresponding to a cable guide member (for example, a fair league not shown), and a holding support part for supporting the mooring rope is provided in the front part on the cable guide member side. 3, and a locking part 5 having a bollard 4 for locking a mooring line is provided at the rear.

6 is a bed 1 between the supporting part 3 and the locking part 5.
It is a rocking body that can stand up and fall freely with the locking part 5 side as a fulcrum, and its base end is connected to a shaft body 7 rotatably supported by both side frames 5a, 5a of the locking part 5. Pair of left and right swing frames 8

With the above configuration, both arms 9, 10 and both swing frames 8A, 8
A cable insertion space A for the mooring rope is formed between the mooring rope and the mooring rope, and a part of the pressing arm 9 forming the cable insertion space A is cut off to create a mooring cable insertion opening 9a for the messenger rope.
is provided.

Incidentally, instead of providing the cutting portion on the pressing arm 9, it may be provided on one of the pair of swing frames 8A and 8B.

The detachment arm 10 is configured to be located above the mooring bollard and the dore 4 when the swing frames 8A and 8B are erected, and its cross section The shape is large.

In addition, as shown in FIG. 4, the detachment arm 10 is arranged so that the eye splice part of the mooring line can easily enter the cable insertion space A.
A mooring rope guide plate 11 is attached to the side opposite to the cable insertion space A, and the detachment arm 10 and the swing frame 8A are attached so that the mooring rope can move smoothly in the cable insertion space A.
, 8B are attached to corner guides 12A and 12B for the mooring rope on the cable insertion space side of the connecting corner.

Reference numeral 13 denotes a cylinder device for raising and laying down the rocking body 6, and is attached via a lever 14 to the end of the shaft body 7 connected to the rocking frames 8A and 8B.

Therefore, in FIG. 1, the cylinder device 13 is indicated by the arrow B
When expanded and contracted as shown by arrow C, the rocking body 6 can freely swing between an upright position (imaginary line position a) and a sideways position (solid line position) as shown by arrow C.

Reference numeral 15 denotes a messenger rope guide which is erected on the locking part 5 at a suitable position behind the locking bollard 4 of the locking part 5, and has a guide groove 16 formed in its top part 15a.

By the way, a pressing member 17 made of rubber or the like is attached to the pressing surface side of the pressing arm 9 to increase friction, and a pair of round rods 18A are attached to the upper part of the support section 3 to increase friction. , 18B (or rubber)
A recess 19 is formed by this.

Note that 20 is a stopper provided at the top of the locking bollard 4 for regulating the swinging position of the swinging body 6, and is adapted to come into contact with the detachment arm 10 of the swinging body 6.

21 is a cover of the cylinder device 13.

Next, the operation will be explained.

First, the cylinder device 13 is extended to make the rocking body 6 stand up.

Then, the messenger rope 22 from the winch (not shown) is passed to the tugboat through the guide plate 15, the cable insertion space A, and the cable guide member.

On this tugboat, the messenger rope 22 is tied to the eye splice 23a of the mooring line 23.

Thereafter, the winch is operated to wind up and pull the metsenger rope 22 onto the deck 2.

As a result, the mooring line 23 is connected to the cable guide member and the cable insertion space A.
It is pulled up through the phantom line a in FIG. 1.

Next, as shown in the imaginary line state in FIG.
The mooring line 23 is held down between the support part 3 and the support part 3.

In fact, this holding is firmly performed by the recess 19 and the pressing member 17, which increase friction.

Then loosen the winch a little.

At this time, the mooring line 23 is held down by the pressing arm 9, so it will not slip down.

Then, the eye splice 23a is hooked onto the mooring bollard 4, and the metsenger rope 21 is removed from the mooring line 23.

Next, the pressure of the cylinder device 13 is relieved, and the rocking body 6 is made free.

As a result, the eye splice 23a is completely locked to the locking bollard 4.

At this time, since the mooring line 23 is always held down by its own weight on the rocking body 6 side, the mooring line 23 is held down by the movement of the tugboat and the ship.
This prevents the bollard from springing up and coming off the locking bollard 4.

Next, when removing the mooring image 23 from the mooring bollard 4, the cylinder device 13 is extended and the rocking body 6 is raised.

As a result, the eye splice 23a is lifted by the detachment arm 10, but since the detachment arm 10 is now placed above the locking bollard 4, it is not possible to separate the eye splice 23a from the locking bollard 4. can.

The mooring image 23 is detached due to its own weight, but since it passes through the cable insertion space A, the detachment is ensured.

Note that even if a large tension is applied to the mooring image 23 after the mooring line is anchored, consideration is given to attaching a knuckle to the rocking body 6 so that the force is not transmitted to the rocking body 6.

Also, by making the top of the locking bollard 4 thinner,
By swinging the rocking body 6 after pulling up the mooring image 23, the eye splice 23a is automatically moved to the mooring bollard 4.
It is also possible to lock it to.

Furthermore, instead of the guide body 15 for guiding the mooring image 23 to the center of the locking bollard 4, a winch may be provided directly on the locking portion 5 of the rear force of the locking bollard 4.

As described above, according to the present invention, the cable guided to the cable guide member can be reliably guided to the locking bollard by the cable insertion space of the swing frame, the guide plate, and the corner guide, and the cable can be reliably guided to the locking bollard. The mooring figure guided by the mooring bollard can be hooked onto the mooring bollard without slipping due to the swinging frame's pressing arm and presser support part, and the hooked rope can be hung on the mooring bollard by the weight of the swinging frame. Since the mooring statue can be held down by the mooring bollard, it can be prevented from coming off the mooring bollard.The height of the mooring bollard can be kept low and compact, yet reliable mooring is possible. This can be done automatically and reliably by standing up the detachment arm.
