Abstract

PURPOSE:To prevent the collision between the quay and the vessel, by providing an adsorbing board to one side while a buffering material to the other side of a buoy vessel and making them freely movable. CONSTITUTION:An adsorbing board 17 is provided movably through a hydraulic cylinder 19 on one side of the hull 11, while a buffer material 22 is provided movably through a hydraulic cylinder 23 on the other side. When mooring at the quay such that the buffer member 22 will push against the quay while applying the adsorbing board 17 to the vessel, the distance between the quay and the vessel can be maintained constant thereby the mooring can be performed in short time.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mooring barge used when mooring a ship to a quay or the like.

For example, when mooring a ship to a quay, conventionally, as shown in Figure 1, the quay (1) and the ship (2) are connected by a mooring line (3), and the The anchor is set and the anchor chain (4) and mooring line (3) are stretched to maintain an appropriate distance (2) between the ship (2) and the quay (1). Although this can prevent the ship 9 from colliding with the quay (1) to some extent, the ship (2) may still collide with the quay (1) due to wind waves and currents.

When a large ship collides with a quay, the ship's mass or inertia is large, so a very large impact force is applied to the ship's shell, potentially causing damage, which is extremely dangerous. Also,
Mooring ropes are stretched between the ship and the quay, which requires a lot of manpower and time.

This invention was made in view of the above circumstances, and aims to provide an extremely safe mooring barge that is easy to moor and can reliably prevent a moored ship from colliding with a quay. purpose.

The present invention will be described below with reference to drawings showing embodiments.

As shown in Figures 2 and 3, the moored barge α
α has a box-shaped hull αD, with an upper deck O at the center of the hull αD.
A vertical plate-shaped cylinder support member (131) is fixed on the upper deck α2 on one side of the support member 031.A horizontal bell bearing side extending perpendicular to the support member αJ is fixed on the upper deck α2 on one side of the support member 031, and a horizontal suction cup support The shaft α9 is fitted into this bearing α so as to be slidable in the axial direction.A vacuum suction cup protruding outward from the hull (Ill) is attached to the outer tip of the support shaft 151. It is attached via the horizontal bin Q61 orthogonal to the suction cup αη and the support shaft αS
A hydraulic cylinder α mark for tilting the suction cup 1 (" 071) is provided between the suction cup 1 (151) and the support member 03 is provided with an oil field cylinder U mark for horizontally moving the support shaft (151) in the axial direction. A horizontal sliding bearing ■ extending perpendicular to member [31] is fixed, and a horizontal cushioning material support shaft c21
1 is fitted into this bearing (2) so as to be freely slidable in the axial direction. A cushioning material (support) made of, for example, rubber and protruding outside the hull circle is fixed to the outer tip of the support shaft at+. An oil field cylinder for horizontally moving the support shaft (2t+) in the axial direction is provided between the inner tip of the cushioning material support shaft C1 and the support member (13).
The support shaft 151 (2+1) and the hydraulic cylinder 09 of the set are arranged on the same horizontal straight line, and by the operation of these cylinders Q91 (23+), the suction cup αη and the buffer material @ move toward and away from each other in the horizontal direction. Moving.

A plurality of wheel bars are provided at the bottom of the hull αD.

Further, although not shown in the drawings, a vacuum pump for operating a suction cup, a ballast tank, equipment for adjusting ballast and driving a hydraulic cylinder, and a control device for these are arranged in the hull pronunciation.

The above-mentioned moored barge αa is floated on the sea surface when in use,
When not in use, it is usually hoisted onto land using a crane. Then, the moored barge O1 is moved by being towed by a trailer or the like on land, or by being towed by a tugboat or the like on the sea. In addition,
The moored barge OIN may be self-propelled.

Figure 3 shows the ship ■ moored to the quay (25) using the mooring barge Oα mentioned above, and two mooring barges tlQ are placed between the quay (b) and the ship ■. ing.

Next, step 1 of the operating procedure when mooring the ship ■ to the quay (to)
Give an example.

Before the arrival of the ship (support), two mooring barges αα are floated on the sea surface and moored to the quay with mooring blanks so that the cushioning material presses against the quay. In this way, electric wires from land are connected to the electric wire connection box of the mooring barge 00 installed on the quay □□□, and oil field pumps, vacuum pumps, etc. are operated, and the wrinkle landing plate aη is moved to the hull α by the operation of the hydraulic cylinder 09.
Make it stick out to the outside of D. Then, the ship (support) is moved using a tugboat, and the bow and stern parts of the ship are pressed against the suction cups Uη of the moored barge Oα. Mooring barge (IG
Now, a sensor detects that the ship □□□) is pressed against the suction cup αη, immediately activates the suction cup 071, and externally detects that the suction cup Uη has reached a predetermined vacuum and has suctioned the ship ■. to be displayed. Once the suction cups αη of the two moored barges αα have both adsorbed the lead cap, the tugboat that was pressing the ship ■ against the mooring barge 10 can be moved to the ship (2)) or the ship ■ can be moved to the suction cup U in this way. '71 is related to ship (1).

This prevents the vessel from leaving the barge αO, and thereby
Since the distance between the ship (4) and the ship (4) is kept constant, the ship □□□
Collision into the quay wall is reliably prevented.

During mooring, the force exerted by the ship (to) on the mooring barge (1G) is calculated by the force exerted by the ship (to) on the mooring barge (1
set of support shafts 0521) and hydraulic cylinders t191 (2
3, there is no risk that the hull (111) will tilt, and no large force will be applied to the hull αI. However, the number and arrangement of the suction cups 071 and the cushioning materials are arbitrary, and one ship may have one so that the force exerted on the mooring barge (IQ) is received by the hull circle.

Further, in the embodiment described above, when the suction cup 0η suctions the ship (2), the suction cup αη can be tilted along the inclination of the ship (A) by operating the oil field cylinder Q81. However, the suction cup αη may not be tilted.

Furthermore, the number of mooring barges O1 arranged between the quay and the ship can be changed as appropriate, taking into consideration the size of the ship, weather conditions, and the like.

According to the mooring barge of the present invention, a suction cup Oη protruding outward from the hull 011 is provided on one side of the hull Uυ, and a buffer material protruding outward from the hull till on the other side of the hull 011. Since the suction cup (17+) and the buffer material container are movable in a substantially horizontal direction that approaches and separates each other, as mentioned above, the buffer material is pressed against the quay wall. moor it to the quay and attach it to the suction cup Gη.
By adhering to the ship, it is possible to maintain a constant distance between the quay and the ship and reliably prevent ship collisions.

In addition, the ship can be moored by an extremely simple operation of pressing the ship against the suction cup Oη of the mooring barge installed on the quay and activating the suction cup (171).
Since mooring operations can be performed remotely, mooring operations can be carried out by a smaller number of workers in a shorter time than conventional mooring operations using mooring lines. In addition, mooring barges can be moved and hung freely, so by simply owning the minimum required number of mooring barges, you can change the arrangement of the mooring barges according to the size of the ship, and adjust the mooring barges accordingly. You can freely choose the location.
