Description

[Detailed explanation of the idea] Industrial applications The present invention relates to an improvement of a boarding device.

BACKGROUND TECHNOLOGY As shown in FIG.
It is configured to be slid by an air cylinder 03 or a wire.

Problems to be Solved by the Invention In such a conventional board device, however, since the angle of inclination of the top surface of the board 1 is approximately 20° or less,
Even if the length of the board 1 is set to about 2 m, the vertical movement distance of the board head 2 is only 200 to 300 mm, and in the end, it has to be used in combination with a fixed board, and every time the ship docks. , it was necessary to drain the dock and repair the board.

The present invention was made in order to solve the problems of the conventional technology, and aims to provide a boarding device that allows a ship to dock and undocks at the same time without draining the dock. purpose.

Means for Solving the Problems In order to solve the above problems, the board device according to the present invention includes a pedestal, a fixed board attached to the center of the mount, and parts on both sides of the fixed board. a pair of movable plates placed on the top surface of the pedestal; a pair of cylinders attached to both sides of the pedestal; piston rods connected to the associated movable plates; and a pair of cylinders that are alternately operated; and the fixed plate. A tree and the movable board are connected, and by extension of the piston rod of the cylinder, the cylinder is rotated 90 degrees around the connection point with the fixed board, and the pair of movable boards are alternately connected to the fixed board. It includes a plurality of arms that are placed on the top surface.

Effect: According to the above means, a pair of movable plates are provided which can be alternately rotated by 90 degrees by a cylinder and an arm,
By using these movable boards by placing them alternately on the upper surface of the fixed board, the ship can be docked and undocking simultaneously without draining the dock.

Embodiment An embodiment of the present invention will be described in detail below with reference to the drawings.

In FIG. 2, reference numeral 1 generally indicates a boarding device according to this embodiment, and this boarding device 1 includes a pedestal 2 having an inverted trapezoidal shape. A fixed board 3 is attached to the center of this frame 2, and a pair of movable boards 4,
5 is placed on the top surface of the pedestal 2. Each of these movable plates 4, 5 is connected via pins 8, 9 to associated piston rods 6a, 7a of a pair of air cylinders 6, 7 attached to both sides of the pedestal 2, respectively.

In addition, each movable board 4, 5 is connected to a fixed board 3, respectively.
and are connected by arms 10 and 11. Each of these arms 10, 11 has one end connected to the movable plates 4, 5 together with the piston rods 6a, 7a of the air cylinders 6, 7 by the aforementioned pins 8, 9, and the other The ends are connected to the fixed board 3 by pins 12 and 13,
Piston rods 6a, 7a of air cylinders 6, 7
Due to the extension of the movable board 4, it rotates 90 degrees around the connection point with the fixed board 3, that is, the pins 12 and 13, and the movable board 4,
5 is placed on the upper surface of the fixed board 3. However, the pair of air cylinders 6 and 7 are operated alternately, and therefore the pair of movable plates 4 and 5 are placed alternately on the upper surface of the fixed plate 3, and in FIG. 3, the movable plate 4 is fixed. The state shown is that it is placed on the upper surface of board 3.

For example, the fixed board 3 has a width of 600 mm and a length of 1200 mm.
It is said to be approximately 1,400 mm in size and 1,400 mm in height. Also,
Instead of the air cylinders 6 and 7, other cylinders such as hydraulic cylinders and motor cylinders can also be used.

Next, a method of using the board device 1 according to this embodiment will be explained.

As shown on the left side of FIG. 4, the docked ship 14 is supported by one movable board 4 placed on the upper surface of the fixed board 3 via the adjustment member 15 by the operation of one air cylinder 6. The other air cylinder 7
is inoperative, and the other movable board 5 rests on the top surface of the pedestal 2.

As shown on the right side of FIG. 4, if the bottom slope of the next docked ship 16 is different from the bottom slope of the current docked ship 14, the other movable board 5 is used.

That is, when this movable board 5 is placed on the top surface of the pedestal 2 as shown on the left side of FIG.
An adjustment material 17 is attached to the upper surface of the movable board 5 on the pedestal 2 in advance by skimming or the like so that the height of the movable board 5 matches the bottom slope of the next docked ship 16. After the currently docked dock 14 leaves the dock, one movable board 4 is moved onto the pedestal 2 by deactivating one air cylinder 6 and activating the other air cylinder 7 while the dock is filled with water. At the same time, the other movable board 5 is placed on the upper surface of the fixed board 3 so as to support the next docked ship 16 via the adjusting member 17. Thereafter, in the same manner, an adjustment material matching the bottom slope of the next docked ship is attached to the upper surface of the movable board 4 in advance.

As shown in FIG. 5, the air cylinders 6 and 7 are connected by air hoses 21, 22, 23, and an air hose 24, which extends to the dock side.
The air cylinders 6, 7 are operated by the valves 26, 27 attached to the piston rods 6a, 7.
A is controlled by remote control so that it alternately expands and contracts.

In addition, since the air cylinders 6 and 7 always operate underwater, buoyancy acts on the movable plates 4 and 5, and the force is extremely small (therefore, the air cylinders can be of small diameter). ) is operational.

Effects of the invention As stated above, the board device according to the invention has the following effects:
It is equipped with a pair of movable boards that can be rotated 90 degrees alternately by cylinders and arms, and these movable boards can be used alternately for ships in dock, so a ship's board is always in the dock of the previous ship. Therefore, ships can be loaded and unloaded at the same time while the dock is full of water, significantly reducing the amount of time and man-hours compared to the traditional method of draining the dock and repairing the board. can be shortened.

Furthermore, the boarding device according to the present invention overcomes the problem that conventional sliding boarding devices can only provide a lifting height of about 200 mm, making it possible to prepare boards that can accommodate any ship's bottom slope. In the conventional boarding device, the upper surface of the board head was horizontal (so that it could be used on ships with zero slope), but in the boarding device of the present invention, the movable board was prepared with a slope. You can also.

Furthermore, with conventional sliding board systems, the docking ship slides the board head (that is, activates an air cylinder) after the keel is touched, and depending on the bottom structure and strength, there is a concern that the board head may push up the bottom of the ship. However, the board device according to the present invention is
Since the height of the board can be set accurately according to the installation location, there is no chance of dents or damage to the bottom shell.
