【Example】

An embodiment of the present invention will be described below with reference to the drawings. In the diagram, 1 is the sea level, 2 is the port or or a mooring facility at a sea berth, etc. 3 is the hull. In this embodiment, at multiple locations on the mooring facility 2 (see Figure 4), The gate-shaped frame 4 is erected. This portal frame 4 is shown in detail in FIGS. 1 to 3. In this case, two steel pipe supports 4a and a ceiling beam 4b made of shaped steel are framed in a gate shape. Therefore, vertical rails 5 are provided protruding inside each of the pillars 4a, and these rails are A vertical guide 7 is installed on both sides of the support 5 via a number of brackets 6 protruding from the support 4a. A pulley support beam 8 is provided at the upper end of these guides 7.

[0008] In addition, the vertical rails 5 and Four guide rollers 10 that come into contact with each other are provided via a bracket 11, and the Guide rollers 12 loosely fitted between the vertical guides 7 are installed above and below the left and right sides of the elevating member 9. Each is provided via a bracket 13, and is raised and lowered by these guide rollers 10 and 12. The structure is such that the member 9 can be guided up and down.

[0009] As this drive device, hydraulic cylinders 14 ( (see Figure 1) is installed vertically, and the lower end of the cylinder 14 is connected to the support 4 by a bracket 15. a, and a clevis 16 at the tip of each piston rod 14a. A pulley 17 is provided. Also, four pulleys 18, 19, 20, 21 are attached to the pulley support beam 8. At the same time, a pulley 23 is provided on the upper part of the elevating member 9 via a bracket 22, As shown in FIG. 1, the cable 24 with one end 24a fixed to the top of the left column 4a is Pulley 17 on the side, pulleys 18, 19, 23, 20, 21, and pulley 1 on the right side 7, and the cable end 24b is tied to the upper part of the right support column 4a.

0010 Further, a joint 25 having a vertical shaft 25a is provided on the front surface of the elevating member 9, and this joint 25 has a vertical shaft 25a. A fender mounting base 26 is provided at the front of the joint 25. A hollow cylindrical rubber fender 27 is provided protruding from the front surface of the rubber fender 27. A vacuum suction cup 28 is provided. Note that 28a is a soft and flexible rubber ring. A lip rubber 29 in the shape of a hook is used to hold the suction cup 28 between the base 26 and the suction cup 28. A horizontal chain having a turnbuckle 29a stretched between, 30 is a turnback This is a lifting chain having a loop 30a. In addition, 31 (see Figure 4) is a mooring pole installed on mooring facility 2 as an auxiliary mooring facility. (bollard), and 32 is a rope for mooring.

[0011] Next, the operation of the device of the present invention constructed as described above will be explained. The fender and fender of this invention As shown in Figure 4, the adsorption type mooring devices for place To moor the hull 3, first operate the hydraulic cylinder 14 to move the suction cup 28. Set it to the desired height. Usually set in a low position when there is a lot of cargo and at low tide. and set it to the high position when the vessel is empty and at high tide. Figures 1, 2 and 5 are suction cups. 28 is shown in a low position, but in order to raise the suction cup 28 from this state, operates the hydraulic cylinder 14 to lower the piston rod 14a. piston When the rod 14a descends, the pulley 17 moves to the position shown in the chain double-dashed line in FIG. The pulley 23 pivotally supported on the elevating member 9 via the rope 24 is raised, and the elevating member Raise 9. When the elevating member 9 rises, the suction cup 28 also rises accordingly. . Further, in order to lower the suction cup 28, the above-mentioned operation may be reversed.

0012 When the height adjustment of the suction cup 28 is completed in this way, the moored hull 3 is moored. While approaching the facility 2 and pressing the lip rubber 28a of the suction cup 28 onto the hull 3, Operate the vacuum unit (not shown) and attach the suction cup 2 through the vacuum suction pipe (not shown). The interior of the lip rubber 28a of No. 8 becomes negative pressure, and the suction cup 28 strongly adsorbs to the hull 3. do. This device can moor the ship 3 in this way, but in the case of a large ship The hull 3 may be vertically large relative to the mooring facility 2 due to loading conditions, low tide, etc. Because of this, when moored for long periods of time, it is necessary to absorb the vertical fluctuations. Therefore, in the device of the present invention, after the ship is moored by the suction cup 28, each hydraulic cylinder 1 Leave each of 4 free. By doing this, the vertical movement of the moored ship will be prevented. Also, it can sufficiently absorb the rocking of the ship.

[0013] Note that if the vertical movement of the hull 3 cannot be absorbed only by the height of the portal frame 4, In this case, as shown in Fig. 5, as shown in Fig. At the (b) position, the suction cup 28 is attached to the hull 3 at the upper limit position of (c) and (d). When this is reached, release the suction of the suction cup 28 at position (d), and Operate the cylinder 14 to lower the suction cup 28 from position (d) to position (b). At the position (b), attach it to the hull 3 again. Next, attach suction cup 28 of A in the same manner (c) Move it from the position to the position (A) and attach it to the hull 3. By repeating the above operations, the device of the present invention can be used to increase the size of a large ship. It can also handle vertical movements. In addition, when the hull 3 descends, the above-mentioned operation is performed. You can do it in reverse.

[0014]

[Effect of the idea]

As mentioned above, in this invention, a vacuum suction cup is installed on the front of the rubber fender. Therefore, this device uses a vacuum suction cup to suction the ship's hull, and also serves as a fender. can be fulfilled at the same time. Therefore, according to the present invention, a separate fender is installed at the mooring facility. In addition to eliminating the need to provide a mooring facility with ropes used as an auxiliary mooring facility, The many rope mooring facilities that were previously required are no longer necessary.

[0015] In addition, the device of this invention has a gate-shaped frame erected at the mooring facility, and A lifting member is provided that can be moved downward, and a joint having an axis perpendicular to the lifting member is provided. Connect the fender mounting base through the The shape of the rubber fender and the vacuum suction cup make it possible to adjust the angle and appearance of the ship when approaching and leaving the berth. Vertical movements of the hull that occur constantly during docking and mooring operations, or horizontal movement of the outer surface of the hull when berthed. In addition to being able to smoothly respond to angle changes in the direction and vertical directions, the It continuously follows changes in stuttering water and can correct the suction position. Therefore, according to the device of the present invention, mooring facilities can be simplified and labor-saving can be promoted. This not only significantly improves mooring efficiency, but also improves work safety. This provides an excellent effect in that it can be used in various ways.
