Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a ship landing station, in particular:
The present invention relates to a ship landing station suitable for use in a maritime city.

Conventional Technologies and Problems Conventionally, at ship terminals, ships were docked alongside the quay, and the ships were secured to the sea with anchors or to the quay with ropes. However, such conventional terminals have the disadvantage that when loading or unloading cargo onto or from a ship, or when people get on or off the ship, the ship shakes, making it difficult to carry out loading and unloading operations smoothly. In addition, when the ship rocks, it can cause discomfort to people getting on and off the ship, and sometimes there is a danger that the people getting on and off the ship may fall into the water.

Means for Solving the Problems It is an object of the present invention to provide a ship launching and landing station that eliminates the drawbacks of the prior art as described above.

In order to achieve this object, the present invention lifts and securely fixes a vessel in a predetermined position, allows for smooth loading and unloading operations, and ensures safe boarding and disembarkation of passengers.

Embodiments Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

Referring to FIG. 1, there is shown an embodiment in which a ship departure and arrival station according to the present invention is applied to a maritime city. This marine city is disclosed in detail in Japanese Patent Application Laid-open No. 70213/1983, filed by the present applicant, so please refer to that publication. Simply put, this marine city consists of a plurality of pedestals 11 with buoyancy tanks extending from the lower surface 10 of the marine structure and having their lower ends attached to the seabed.

The ship launching and landing station of the present invention has a base frame 20 fixed to a pedestal 11 and a support mechanism 21 attached to this base frame. This support mechanism supports the ship 22. This support mechanism is adjustable and attached to the base frame so that it can be supported appropriately depending on the size of the ship. This support mechanism includes a first frame 23 attached to a base frame so as to be movable in the longitudinal direction of the vessel 22, and a second frame 24 attached to the first frame so as to be movable in the left-right direction of the vessel. Toko no 2
It consists of a plurality of pedestals 25 attached to a frame body. These cradles are arranged to receive a vessel and have a receiving surface 26 for receiving the bottom of the vessel. These pedestals are attached to the second frame by means of cylinders (not shown) so that they can move up and down in the vertical direction. These pedestals are raised and lowered by driving means (not shown).

In addition, the lifting and lowering of the pedestal 25 and the first and second frames 2
3 and 24, that is, control of the drive means, is performed by a computer (not shown) from a control room installed at an arbitrary location on the marine structure.

In order to ensure that the vessel 22 is supported by the pedestal 25, a positioning mechanism 30 is provided for positioning the vessel at a supporting position above the cradle 25. In the illustrated embodiment, the positioning mechanism includes:
A laser generating means 31, a laser beam reading device 33 that receives a plurality of laser beams 32 outputted from the laser generating means 31, converts them into electrical signals, and provides the converted signals to the computer, and an index 34 for determining the center of the ship. It is completed.

When the ship 22 approaches the departure and arrival station and crosses the laser beam 32, the speed of the ship is calculated by the laser light reader 34 and the computer, and the speed is reduced so that the ship 22 stops directly below the ship departure and arrival station. As such, a speed control command is given to the driver of the vessel 22 from the control room. The driver moves the boat at a speed according to the control command and while watching the indicator 35. On the other hand, the computer has various ship shapes and a cradle 25 for each ship shape.
The computer reads out ship support position data corresponding to the shape of the ship 22 read by the laser light reader 33.
Then, the computer controls the driving means according to the read ship support position data, and moves the first frame 23 and the second frame 24 to a predetermined position where the ship 22 is to be supported, that is, a receiving position. The position of the stand 25 is moved to a position that matches the computer ship support position data.

When the ship 22 stops directly below the ship departure/arrival station and the pedestal 25 is set at the ship support position, the cylinder moves upward and supports the ship 22.
The bottom of the ship is supported by a pedestal 25. After this, the frame bodies 23 and 24 are
is moved together with the ship 22, and minute position corrections are made to the specified position directly below the ship departure and arrival station. In addition,
In order to support the ship under the sea surface, where its weight is slightly higher due to balance with buoyancy, it may be possible to install a means to detect the water line with a laser and position it vertically, but depending on the shape of the ship, it is possible to install a means to position the ship in the same position in multiple locations. It is preferable to support it on a pedestal as it will not be affected by waves.

The ship is securely secured in the manner described above.

The offshore structure is provided with a gate 40 for loading cargo onto or from a ship, or for unloading people. An elevator 41 is provided at this gate,
This elevator is used to load cargo onto the ship.

Effects of the Invention According to the present invention, since the ship is lifted and supported by a pedestal, the ship can be supported without shaking, and therefore loading and unloading cargo or loading and unloading of people can be carried out smoothly. There is a practical benefit of being able to do it safely.

In the above embodiment, the positioning mechanism is performed using a laser beam or the like, but it is also possible to assemble a plurality of frames to perform the positioning mechanically.
