Description

[Detailed description of the invention] TECHNICAL FIELD This invention relates to a ship docking/undocking device.

Traditionally, ships have been docked and undocking by towing the ship with a wire rope rope, but with such rope-towing devices, it is necessary to attach and remove the rope to and from the ship when docking and undocking. Since this is done with input from multiple 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.

An object of the present invention is to provide a ship docking and docking device that solves the above-mentioned problems and can save labor and improve safety in docking and docking work.

An arm 31 that rotates in a horizontal plane is attached by 0,
A roller 5 that rotates around a vertical axis is attached to the rotation end of this arm 310.

Each of the running bodies 4 and 6 on the opposite side wall 2 has a structure symmetrical to each of the above-mentioned running bodies 4 and 6, respectively.

Next, an example of the operating procedure at the time of docking will be described with reference to FIGS. 7 and 8.

Figure 7 shows the procedure when the wind is blowing from the upper side of the figure, that is, from the port side of the ship 32. Before starting work, each of the traveling bodies 4 and 6 on both sides are located near the dock 10. The elevating body 15 of the traveling body 4 with a suction cup is fixed to the upper part of the leg 10 by a hydraulic cylinder pin type stopper (as shown), and the arms 19 and 31 of each traveling body 4 and 6 are fixed to the upper part of the leg 10 by a similar stopper as shown in FIG. and are fixed at storage positions A and B indicated by chain lines in FIG.

In this state, the tugboat 33 placed on the leeward side, that is, the starboard side, of the ship 32 guides the ship 32 to the dock 1 near sunset, and puts its bow into the dock 1.

Once the bow has slightly entered the dock 1, rotate the arm 19 of the suction cup-equipped traveling body 4 on the windward side toward the ship 32, and adjust the horizontal and vertical inclinations of the suction cup 3 as appropriate. Then, suction the port side hull plate on the bow side with the suction cup 3 (see Figure 7 A).

Next, the ship 32 is further drawn into the dock 1 by moving the traveling body 4 that has absorbed the ship's side shell plate to the right side in FIG.

At this time, the load acting sideways on the ship 32 due to the wind is received by the traveling body 4 that has attracted the ship 32 and the tugboat 33 outside the dock 1.

In addition, when a large towing force is required, the traveling body 4 with suction plate and the traveling body 6 with rollers can be connected to create two traveling bodies 4, 6.
The vessel 32 is towed and towed.

Once the bow of the vessel 32 has entered the dock to some extent, rotate the arm 31 of the roller-equipped traveling body 6 on the leeward side toward the vessel 32, and press the roller 5 against the starboard side outer plate on the bow side ( (See Figure 7).

Then, the load acting sideways on the ship 32 is received by the traveling bodies 4 and 6 on both sides of the bow and the tug board 33, and the attitude of the ship 32 is adjusted so that the no gland in the hull is as parallel as possible to the center line of the dock 1. At the same time, the ship 32 is further pulled into the dock 1.

If approximately 2/3 of the total length of ship 32 is inside dock 1,
The suction cup 3 of the traveling body 4 on the leeward side suctions the starboard side outer plate of the stern section in the same manner as described above, and the two traveling bodies 4 with suction plates suction the ship 32.
While towing and towing the ship, the ship 32 is further pulled into the dock 1 while adjusting the attitude of the ship 32 using the three traveling bodies 4 and 6 (see the entrance in Figure 8).

When the ship 32 is pulled in to a predetermined position, the traveling bodies 4 and 6 are stopped, and the tug boat 33 connected to the stern brakes and stops the vessel 32, and the arms 19 of the three traveling bodies 4 and 6 are stopped. By appropriately rotating the angle 31, positioning of the vessel 320 in the width direction is performed (see Figure 8).

Then, the tugboat 33 is separated from the ship 32 and
Close the 0 entry log gate 34 (see the seventh diagram).

A plurality of boards 36 and 37 are placed at predetermined positions on the bottom 35 of the dock 1 before the ship 32 is pulled in, and after the entrance gate 34 is closed, the water in the dock 1 is discharged at full speed. do(
(See Figure 8).

As the water level in the dock 1 decreases, the ship 32 also gradually lowers.The stopper for storing the elevating body 15 of the traveling body 4 with a car suction plate, which is fixed to the leg 10, is removed, and the brake of the winch 17 is made to slip. Accordingly, the elevating body 1
5 follows the ship 32 and descends.

In addition, the amount of protrusion (amount of rotation) of the arm 31 of the roller-equipped traveling body 6 is changed according to the shape of the outer plate of the descending ship 32,
The roller 5 is always pressed against the ship 32 with a constant force.

In this way, the two sets of suction cups 3 adsorbed to the ship 32 and one roller 5 pressed against the ship 32 keep the horizontal position of the ship descending constant.

Then, when the vertical distance between the bottom of the ship and the center board 36 reaches a certain value, the system switches to half-speed drainage (see the entrance in Figure 8), and when the bottom of the ship reaches the center board 36, the drainage is stopped. and inspect the position of the vessel 32 (see Figure 8).

If the ship 32 is not positioned correctly, water is poured into the dock 1 to return it to the state at the entrance in Figure 8, the position of the ship 32 is adjusted, and then the same operation as described above is performed.

When the ship 32 is correctly positioned, the heights of the boards 3T on both sides are adjusted so that all the boards 36 and 37 receive the ship 32, and the suction cups 3 and the suction cups of the three traveling bodies 4 and 6 The roller 5 is moved away from the vessel 32 to the storage position A.

At the same time, the elevating bodies 15 of the two traveling bodies 4 with suction cups are raised and fixed to the upper part of the legs 10 and stored.

(See Figure 8). Then, the water is drained again at full speed (see figure 8), and eventually all the water in the dock 1 is drained and the work is completed, and the ship 32 is supported on the boards 36 and 37 (see figure 8).
(see figure).

The above operations can be performed automatically by using various sensors and microcomputers that detect the horizontal position and vertical position of the ship 32, or can be performed semi-automatically by manual operation.

Even when the direction of the wind or the current is opposite to that described above, the only difference is that the position of the tugboat 33 and the operating order of the traveling bodies 4.6 on both side walls 2 are reversed, and the rest is the same as described above.

In addition, if the width of the ship is considerably smaller than the width of the dock 10, the bow of the ship is suctioned by the traveling body 4 with a suction cup on one side, and the stern part is suctioned with the traveling body 4 with a suction cup on the opposite side. After the ship is held diagonally and in this state is towed and towed to a predetermined position by the two traveling bodies 4, the ship can be positioned using work winches placed around the dock 1. can.

In addition, in the case of draining, the operation opposite to the above may be performed.

The configuration of each running body 4, 6 is not limited to that of the above embodiment,
It can be changed as appropriate.

For example, in the above embodiment, each of the traveling bodies 4 and 6 is a self-propelled type equipped with a motor, but the traveling bodies 4 and 6 may be moved by a winch around the dock 1.

Furthermore, the arrangement of the rails 8 and 9 for the traveling body with a suction cup is arbitrary; for example, a rail that supports the weight of the traveling body 40 is provided at the bottom 35 of the dock 1, and a rail for preventing the traveling body from falling is provided on the upper part of the side wall 2. You may also use a furnace.

Further, like the suction cup 3, the roller 5 may also be able to move up and down following the ship 32.

Alternatively, the roller may be spherical and can rotate in either direction.

The number of suction cups 3 and rollers 5 of each traveling body 4, 6 is arbitrary.

Two or more traveling bodies 4 with suction cups may be provided on each side wall 2.

The same applies to the roller-equipped traveling body 6.

According to the ship loading/undocking device of the present invention, the traveling body 4 with a suction cup attracts, pulls, and tows the ship 32, and the traveling body 6 with rollers receives a load acting sideways on the ship 32. By adjusting its attitude, it is possible to carry out docking and docking work 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 save labor and improve safety in input/output work.

In addition, since the traveling body 4 with a suction cup and the traveling body 6 with a roller are provided on both sides of the dock 1, it is possible to use them depending on the wind direction and the direction of the current.In addition, the suction cup 3 can be moved up and down. Because it can move up and down while holding the ship 32, it is easy to position the ship 32, especially when docking. It can be made to bottom.

Furthermore, the elevating body 15 of the traveling body 4 with a suction cup and the art 1
9 and the arm 31 of the roller-equipped traveling body 6 are connected to the dock side wall 2.
Since the suction cup 3 and the roller 5 are provided at the rotating ends of these arms 19 and 31,
There is no need to provide the part for raising and lowering the suction cup 3 and the part for advancing and retracting the suction cup 3 and rollers 5 on the outside of the dock side wall 2, and the amount of protrusion of these running bodies 4.6 to the outside of the dock side wall 2 is small. Finish.

Therefore, there is no need to secure a large space outside the dock side wall 2Q for moving the traveling bodies 4 and 6 and raising and lowering the suction cup 3, which is economical.
