Description

[Detailed explanation of the idea] This invention relates to a device for entering and exiting a ship.

Traditionally, ships have been docked and undocking by towing them with wire ropes, but with such rope-towing devices, it is not necessary to attach or remove the rope from the ship when docking or undocking. Since this work is done manually by many workers, there is a temporary peak in work and there are safety issues.

Additionally, as the docks expand, the ships entering and exiting the docks also become larger, and the diameter of the ropes increases, further increasing the peak of this work.

The purpose of this invention is to provide a ship docking and docking device that solves the above problems and can save labor and improve safety in docking and docking work.

This invention will be explained below with reference to drawings showing embodiments.

Four vacuum suction cups 22 are fixed to.

A hydraulic cylinder (fluid pressure cylinder) 230 that rotates the suction cup 22 in a horizontal plane is attached at both ends to a lever 24 and an arm 18 that rotate together with the rotation member 20, and the suction cup 22
Both ends 25 of a hydraulic cylinder (hydraulic cylinder) that rotates the holder in a vertical plane are attached to the suction cup mounting member 21 and the rotating member 20.

Although not shown, the elevating body 14 is provided with a vacuum unit that operates the suction cup 22 and a hydraulic unit that operates each cylinder 19, 23, 25.

The other input/output device 4 has substantially the same structure as the above-mentioned input/output device 3, and runs on the same rail 6°7.

In addition, in these two inlet/outlet devices 3.4, the elevating body 14
The structures of the two move forward and backward with respect to the moving direction of the traveling body 8.

Next, an example of the operating procedure at the time of docking will be explained with reference to FIGS. 4 and 5.

First, the tugboat 26 is used to guide the vessel 27 to the dock 1 near the entry point, and the bow section is placed into the dock 1 (see the entrance in Figure 4).

At this time, the two docking devices 3 and 4 are located near the dock 10, and the elevating body 14 is fixed to the upper part of the leg 9 of the traveling body 8 by a hydraulic cylinder pin type stopper (as shown). , the suction cup 22 or the arm 18 is fixed by a similar stopper in the retracted position A shown in chain lines in FIG.

Once the bow of vessel 27 has entered dock 1 to some extent,
Rotate the arm 18 of the loading/unloading device 3 on the right side of FIG. Adsorb (see the opening in Figure 4).

Once the ship's side shell has been suctioned, the arm 18 is fixed to the towing position B shown by the chain line in Figure 1 using a hydraulic cylinder type pin stopper (as shown), and the tugboat 26 is used to adjust the ship's attitude while moving the ship to the right side. By moving the loading/unloading device 3 to the right side, the ship 27 is pulled into the dock 1.

Once most of the ship 270 has entered the dock 1, the suction cup 22 of the left docking device 4 is used to suction the side shell plate of the stern section in the same manner as described above, and the arm 18 is fixed in the towing position, and the two By moving the docking devices 3 and 4 to the right, the ship 27 is further drawn into the dock 1 (see the entrance in Figure 4).

Once the vessel 27 has been pulled in to a predetermined position, the two docking/docking devices 3 and 4 are stopped, and the tugboat 26 connected to the stern brakes and stops the vessel 27, and the arms of each device 3 and 4 are stopped. By appropriately rotating 18,
Position the vessel 21 in the width direction (see Figure 4)
.

Then, the tugboat 26 was separated from the vessel 27 and
Close the 0 entry log gate 28 (see the opening in Figure 4).

Before pulling in the ship 27, a plurality of boards 30 and 31 are placed in the bottom 29 of the dock 1 at predetermined positions, and after closing the entrance gate 28, the water in the dock 1 is drained at full speed. do(
(See Figure 4).

As the water level in the dock i decreases, the ship 27 also gradually descends, but by removing the storage stopper that fixes the elevating body 14 to the leg 9 of the traveling body 8 and slipping the brake of the winch 16, The elevating body 14 is the ship 2
7, and the position of the ship 27 in the horizontal plane is maintained constant.

Then, when the vertical distance between the bottom of the ship and the center board 30 reaches a certain value, it switches to half-speed drainage (see the entrance in Figure 5), and when the bottom of the ship reaches the center board 30, the drainage is stopped. and inspect the position of vessel 27 (see the entrance in Figure 5).

If the ship 27 is not positioned correctly, water is poured into the dock 1 to return it to the state at the entrance in Figure 5, the position of the ship 27 is adjusted, and then the same operation as described above is performed.

When the ship 27 is positioned correctly, the heights of the boards 31 on both sides are adjusted so that all the boards 30 and 31 receive the ship 27, and the suction cups 22 of the two docking/docking devices 3 and 4 is separated from the vessel 27 and fixed at the storage position A, and the elevating body 14 is raised and fixed to the upper part of the leg 9 of the traveling body 8 and stored (see the beginning of FIG. 5).

Then, the water is drained at full speed again (see the entrance in Figure 5), and eventually all the water in the dock 1 is drained and the work is completed, and the ship 27 is supported on the boards 30 and 31 (see Figure 5). .

The above operations can be performed automatically by using various sensors and microcomputers that detect the horizontal position and vertical position of the ship 27, or can be performed semi-automatically by manual operation.

In the case of draining, the above operation may be performed in reverse.

In the above embodiment, the traveling body 8 is a self-propelled type equipped with a motor, but the traveling body 8 may be moved by a winch placed around the dock 1.

Further, the arrangement of the rails 6 and 7 for the traveling bodies is arbitrary; for example, a rail supporting the weight of the traveling bodies 80 may be provided on the bottom 29 of the dock 1, and a rail for preventing the traveling bodies from falling may be provided on the upper part of the side wall 2. Good too.

Further, the elevating device for the elevating body 14 is not limited to the winch 16.

Further, the number of suction cups 22 and the number of input/output devices provided in the dock 1 are also arbitrary.

Furthermore, the configuration of other parts of the inlet/outlet device is not limited to that of the above embodiment, and can be modified as appropriate.

As described above, the ship docking/undocking device according to this invention has a pair of legs 9 extending vertically along the side wall 2 of the dock 1, and a traveling body 8 that moves in a substantially horizontal direction along the side wall 2. , an elevating body 14 disposed between these legs 90 , an elevating device 16 provided on the running body 8 and for moving the elevating body 14 up and down along the legs 9 , and an elevating device 16 whose one end is pivotable to the elevating body 14 . An arm 18 that is freely attached, a fluid pressure cylinder 19 that rotates the arm 18 in a substantially horizontal plane, and a fluid pressure cylinder 19 that is rotatably attached to the rotating end of the arm 18 via a rotating member 20 and a suction cup mounting member 21. It is equipped with a suction cup 22, a fluid pressure cylinder 23 that rotates the suction cup 22 in a substantially horizontal plane, and a fluid pressure cylinder 25 that rotates the suction cup 22 in a substantially vertical plane. It can be attracted to the board 22 and pulled into or pulled out from the dock 1.

Since the suction cup 22 can move up and down while adsorbing the ship, it is easy to position the ship, especially when docking, and the ship can be placed on the board in the dock 1 while maintaining a constant horizontal position. It can be bottomed out.

As described above, according to this invention, it is possible to carry out docking and docking work for ships without using a wire rope for towing other than a tugboat, and it is also possible to automate the work.

Therefore, it does not require as many workers as in the past,
It is possible to reduce the number of people, reduce labor in drain work, and improve safety.
