Description

[Detailed Description of the Invention] The present invention relates to an adsorption type mooring device for mooring a ship to a quay.

When a ship is moored to a quay, the relative position between the ship and the mooring device changes due to the ebb and flow of the tide or changes in water levels due to loading and unloading.

As a conventional mooring device to deal with such a case, as shown in Fig. 1, a suction cup up-and-down device is used, in which the quay wall a is cut down to form a section, and a suction cup can be moved up and down on this stepped section. C is installed, and when the ship d moves from position A to position B, the suction cup is moved upward.

However, in this configuration example, the distance that the suction cup moves requires the length of the tidal difference + the amount of change in water, which has the disadvantage of increasing the height of the device C, and the quay wall a has been renovated. Construction work is also required.

Therefore, in order to lower the height of the above-mentioned suction cup up/down device C, a suction cup up/down device cI is installed on the floating pier e as shown in FIG. A method has been proposed that can remove the .

However, this method has the drawback that the manufacturing cost of the floating pier e is very high.

The present invention aims to make it possible to easily follow the movement of moored ships up and down due to tides and changes in water levels, at a low cost and with a low height. A turret is installed on the quay so that it can move forward and backward, and the ends of two parallel support girders whose tips are pivoted to the back side of the suction cup are pivoted to the turret so that they can tilt freely. That is.

Embodiments of the present invention will be described below based on the drawings.

As shown in FIGS. 3 and 4, the gantry 1, which has main rollers 2 and side rollers 3 for running in the front, back, right and left, can be moved in the front and back direction (direction perpendicular to the coastline) on a gantry 5 installed on the quay 4. A hydraulic cylinder 6 for movement is connected to the gantry 1, and the side rollers 3 are guided to the gantry 5 by the expansion and contraction of the cylinder 6, and the gantry 1 is pushed and pulled on the rail 7. Place turret 8 on platform 1.

An elevating frame 9 is attached to the front side of the turret 8, and to the elevating frame 9, each end of two suction cup support beams io and i1 is attached to be tiltable with a pin joint 12, and a lip rubber 14 is attached to the front side. The suction cup 13, which is designed to suck air inside the lip rubber 14 by a vacuum generator (not shown), is attached to the mounting body 15 via the buffer body 16, and each of the suction cup support rods 10, 11 is attached to the mounting body 15. Each tip is attached to be tiltable with a binge joint 17, and when two suction cup support girders 10 and 11 are tilted, the suction cup 13 is displaced in the vertical direction without shaking by performing a parallelogram motion. (Fig. 4 shows the lifted state) The tilting of the support rods io and 1i is controlled by the lifting frame 9 and the support. This is done using a hydraulic cylinder 18 for raising and lowering placed between the rod 10.

In addition, 19 is a manhole provided in the turret 8, and 20 is a ship.

Now, when the ship 20 is berthed and the ship 20 is to be moored, first, the moving hydraulic cylinder 6 is extended and the turret 8 is moored.
advance toward the sea.

At low tide or when the ship 20 has a large amount of water, the ship 20 is at a low position relative to the quay 4.

In this case, the luffing hydraulic cylinder 18 is shortened to tilt the suction cup support girders io and i1 downward, and the suction cup 13
is positioned below as shown by the two-dot chain line in FIG.

Next, while adjusting the position of the turret 8 using the moving hydraulic cylinder 6, the suction cup 13 is brought into contact with the ship's side outer plate of the ship 20, air is sucked into the space between the seal rubber 14 and the ship's side outer plate, and the suction cup 13
is adsorbed onto the ship 20, and the ship is moored.

At this time, the lateral shaking of the vessel 20 is caused by the binge joint 1.
2.17 parts can be absorbed, and the vertical shaking of the ship can be absorbed by moving the oar 80 in the front-rear direction.

Next, if the tide level rises and becomes high tide, or if the vessel 2
If the stuttering of 0 becomes small, the hydraulic cylinder 1 for uphill
8 to extend and raise the suction cup support girder 10.11,
The body should be in a horizontal position.

In this case, since the two support girders io and i1 perform parallelogram motion, the suction cup 13 can move upward while maintaining the same posture, and by gradually retreating the turret 8, the ship 2
It is possible to easily follow the almost vertical rise of 0.

Furthermore, when the ship 20 rises due to a change in water, the elevating frame 9 provided on the turret 8 is raised by a drive mechanism (not shown).

As a result, the suction cup support girders io and 1i are also raised at the same time, making it possible to follow the fluctuations of the ship 20.

Incidentally, the tilting of the suction cup support girders 10 and 11 is performed by using a winch by tying a rope hanging down through the top of the turret 8 to the support girder 11, instead of using the hydraulic cylinder 18 for luffing as in the above embodiment. It is also possible to perform the tilting movement by winding in and letting out the lobes.

Further, instead of using the moving hydraulic cylinder 6, it is also possible to perform rope operation using a winch.

As described above, according to the device of the present invention, (i) The suction cup can be moved smoothly in the vertical direction.

(i[) With the above i), it is possible to easily follow the displacement of the ship in the vertical direction, and the dimensions in FIG. 1 can be reduced.

0ii) There is no need to renovate the existing quay, and it can be easily installed on any quay.

(1ψ It is economical because it eliminates the need for a floating pier like the conventional method shown in Figure 2.

(V) Labor savings can be achieved during ship mooring work.

It can produce excellent effects such as
