It is designed to be used exclusively for ships.

A roller 19 made of a synthetic resin material or the like is rotatably supported on the upper part of the guide bar 17, and when a small boat is parked, the roller 19 rotates to restrict the sides of the small boat. It is designed to guide you smoothly in any situation. Further, the pad member 18 is arranged so that the bow portion of the small boat comes into contact with the pad member 18 when the small boat is parked, thereby positioning the small boat in the longitudinal direction.

As shown in Fig. 1, the boarding buoy 4 is configured to move up and down according to changes in the water level by being supported so that it can move up and down along a guide bar (not shown) installed on the quay. There is. Further, on the side wall of the boarding buoy 4, there is provided a contact member 2o with which the bow of a small boat entering the vessel comes into contact as will be described later, a drive cylinder 21 that moves this contact member 20 in and out, and a drive cylinder 21 for moving the contact member 20 in and out. Protective member 2 that protects the side part

A cable 27 for supplying power to the. The drive wheel 24 is rotationally driven by the drive motor 23 and travels on the transport rail 13, etc., so that the transport vehicle 3 moves back and forth, and the lifting jack 26 is driven up and down by the drive motor 25 to park. It is configured to lift the ship pallet 2 together with a small vessel.

A case will be described below in which a small boat is landed using the landing device configured as described above and is stored in a hangar on land. First, as shown in FIG. 5, the bow and side walls of the small boat to be landed are brought into contact with the abutment member 20 and the protection member 22 of the boarding buoy 4, and the small boat is brought ashore. Next, in response to a wireless operation by the crew of the small boat or a manual operation by an operator on land, the carrier 3 is moved into a hangar (not shown) in which pallets 2 corresponding to the small boat are stored. With the parking pallet 2 lifted up by the lift jack 26, the carrier 3 is moved together with the parking pallet 2 along a rail 27 installed on land (see FIG. 4).

Next, by running the transport vehicle 3 along the transport rail 13 of the elevating frame 9 installed at the landing position,
The parking pallet 2 is moved onto the mounting portion 12 of the lifting frame 9. Then, by lowering the parking pallet 2 on the carrier 3 and placing the parking pallet 2 on the mounting part 12 of the lifting frame 9, the base member 15 of the parking pallet 2 is clamped with the clamp 14. , the parking pallet 2 is fixed to the above-mentioned mounting section 12. Next, the transport vehicle 3
is moved onto the rail 27 on land and placed on standby, then the lift tower 5 is rotated by the swing drive unit 7, and the lift frame 9 is moved above the water surface located in front of the boarding buoy 4, as shown by the imaginary line. move it to

Thereafter, as shown in FIG. 6, the elevating frame 9 is lowered along the elevating guide 8 of the elevating tower 5, and the parking pallet 2 is introduced below the water surface. Then, to the ship approach position where the hull support portion 16 of the parking pallet 2 is located below the bottom of the hull, and the upper ends of the guide bar 17 and pad member 18 of the parking pallet 2 are located above the water surface. The elevating frame 9 and the parking pallet 2 are lowered.

Note that the lowering position of the elevating frame 9 is preferably set to a predetermined position calculated according to the water level detected by a water level detecting device or the like. In this way, the lifting frame 9 can be controlled to be lowered to the optimum position corresponding to the above-mentioned changes in the water level, etc., and it is easier to land small vessels than in the case where the lifting frame 9 is always lowered to the lowest position. The time required can be shortened.

Next, the abutment member 20 of the boarding buoy 4 is retracted to the side by the drive cylinder 21 to release the restraint of the bow part, and then the guide bar 17 and the upper end of the pad member 18 protruding above the water surface are used as landmarks to reduce the size. The ship is moved forward and stopped with the bow of the ship in contact with the pad member 18, and in this state the crew moves onto the boarding buoy 4 and disembarks the ship. In addition, after disembarking at the berthing position shown in FIG. 5, the small boat may be configured to enter above the parking pallet 2 by manual operation.

Next, the elevating frame 9 is gently raised along the landing guide 8 by the drive mechanism IO, and the small boat is placed on the parking pallet 2 by bringing the hull support part 16 of the parking pallet 2 into contact with the lower surface of the hull. After that, the elevating frame 9 is further raised and lifted above the water surface. As shown in FIG. 7, when the elevating frame 9 rises to the upper limit position located on land, the drive mechanism 10 is stopped to hold the elevating frame 9 in the raised position, and the elevating tower 5 is rotated. After moving the aircraft to the above landing position,
The cleaning device 11 cleans the hull and the parking pallet 2 (see FIG. 1).

Thereafter, the carrier 3 is introduced into the elevating frame 9, and with the parking pallet 2 and the small boat lifted by the elevating jack 26, the carrier 3 is moved onto the carrier rails 13 and 2.
The parking pallet 2 and the small boat are moved to a predetermined hangar together with the carrier vehicle 3 and stored therein.

In addition, when the small ships stored in the above hangar depart,
The small boat is moved to a position where it can sail by operating the transport vehicle 3 and the elevating mechanism 1 in substantially the reverse order of the above-described storage operation. That is, when a small ship stored in a predetermined hangar is to be set sail, the transport vehicle 3 enters the hangar and lifts the small ship together with the parked pallet 2, and then the transport vehicle 3 is moved along the transport rail 27.13. 3 is moved, and the parking pallet 2 and the small boat are transported by the carrier 3 into the elevating frame 9 and supported on the mounting section 12, as shown in FIG. Next, after the transport vehicle 3 is evacuated to land, as shown in FIG.
With the lifting frame 9 rotated to position it above the water surface, the driving mechanism 10 lowers the lifting frame 9. As a result, as shown in FIG. 6, the small boat floats on the water surface. After getting on board in this state, the small vessel is backed up and set sail. In addition, the above-mentioned parking pallet 2 is
After being cleaned by the cleaning device 11, it is transported to a hangar via the transport vehicle 3 and stored.

As mentioned above, since the guide bar 17 for guiding the side of the small boat is provided protruding from the side of the parking pallet 2 that supports the small boat, the guide bar 17 is used as a landmark to guide the parking pallet 2. Small vessels can easily and appropriately enter above the area. Furthermore, since a pad member 18 is provided at the front end of the parking pallet 2 to position the bow of the small boat when it is parked, by moving the small boat forward until the bow comes into contact with the pad member 18, The positioning in the front and back direction can be performed accurately.

Therefore, the small boat can be accurately positioned and parked above the parking pallet 2 placed on the placement portion 12 of the lifting frame 9. In the above state, the elevating frame 9 is moved to the drive mechanism 10 of the elevating tower 5.
By raising the small boat by the above, the small boat can be placed on a predetermined position on the parking pallet 2 and raised, and the small boat can be lifted from the water surface very easily. In other words, when the elevating mechanism of the landing device is configured with a winch or the like that pulls up a robe wrapped around the hull of a small boat, as in the conventional device, the small boat is positioned at a predetermined hoisting position and parked. After that, complicated work such as winding the rope around the ship's hull in an appropriate state is required, whereas when using the elevating mechanism 1 and the parking pallet 2 with the above configuration,
A small boat can be automatically lifted from the water surface without the need for the above-mentioned complicated operations.

Furthermore, since the guide bar 17 positions the small boat in the left-right direction, the small boat can be placed in an appropriate state on the hull support section 16 formed corresponding to the bottom of the boat. , the pad member 18
Since the position of the small boat in the longitudinal direction is determined by A small boat can be stably placed on the boat 2, and an excessive load can be prevented from being applied to the boat body.

Furthermore, the landing device described above can land a small boat even when there is a large head difference between the land and the water surface, and its installation location is not limited.

Note that the small vessel landed by the above-mentioned small vessel landing device can be stored in a flat hangar provided on land, but it may also be stored in a hangar equipped with a three-dimensional storage part equipped with an elevator. Alternatively, the landed small boat may be carried from the elevating frame 2 onto a conveyance rail or the like provided on the loading platform of a conveyance vehicle, and may be conveyed to the owner's house by this conveyance vehicle.

Further, in the above embodiment, the parking pallet 2 is configured to be transported by the transport vehicle 3, but the parking pallet 2 is provided with wheels and the parking pallet itself is transported manually or by a drive mechanism. may be configured.

[Effects of the Invention] As explained above, the present invention provides for installing a parking pallet for supporting a small boat on a lifting frame at a ship entry position under water, Since the structure is configured such that a small boat can enter above the parking pallet along the protruding guide rail, the small boat can easily enter above the parking pallet using this guide bar as a landmark. The guide bar can restrain the side portions of the small boat and position it in the width direction easily and reliably. Further, since a pad member is provided protruding from the front end of the parking pallet, the bow of the small boat is brought into contact with the pad member, thereby making it possible to accurately position the small boat in the longitudinal direction.

Therefore, by stopping the small vessel while accurately positioning it above the parking pallet installed at the above-mentioned vessel approach position, and raising the parking pallet together with the elevating frame in this state, the small vessel can be placed on the parking pallet. This allows the small boat to be easily landed while preventing damage to the small boat.

Furthermore, the above landing device has the advantage that its installation position is not limited and can be installed at any location, such as a location where there is a large drop between the land and the water surface.
