Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a hull elevating device for elevating a hull such as a motor boat or a yacht from land to sea or from sea to land.
[0002]
[Prior art]
In motorbikes, yachts, etc. used for leisure purposes in marina, etc., rather than staying on the sea, they are lifted to land after use and placed on a dedicated cart and moved to a predetermined storage location. However, the method of lowering the hull to the sea only at the time of use is superior from the viewpoints of preventing corrosion of the engine and the like, cleaning the hull, maintenance, evacuation during a typhoon, and the like.
[0003]
Conventionally, as a method of raising and lowering the hull between the land and the sea, the carriage on which the hull is placed is moved to the quay using an existing forklift etc., and the carriage is transferred to the vertical lifting device installed on the quay, A method of raising and lowering the hull is generally performed.
[0004]
[Problems to be solved by the invention]
However, the conventional vertical lifting device has a problem that the entire weight of the hull must be supported by the device, the device becomes large, and the equipment cost increases. It is not realistic to handle large ships exceeding about 25 tons.

However, it is difficult to position the hull floating on the sea and the rising bogie, and it is necessary to allocate dedicated personnel for this purpose, especially for large ships, several personnel are allocated. Have the problem of having to do.
[0006]
In addition, when a passenger rides on a hull placed on land at the time of departure, he / she must board a ladder, and when a passenger gets off from a hull which has moved to land at the time of return, the ladder is also taken. There was a drawback of having to get off.
[0007]
On the other hand, when repairing a hull at a shipyard or the like, the hull is fixed to a traveling platform that runs on a rail laid on an inclined surface from the land to the sea. It has the problem of requiring a lot of time and manpower.
[0008]
The present invention solves the above-mentioned conventional problems, and can raise and lower a large hull with low-cost equipment, can eliminate the need for personnel for raising and lowering the hull, It is an object of the present invention to provide a hull elevating device capable of easily getting on and off a passenger and a carriage used for the device.

The platform 21 is made of punching metal or a wire mesh.
[0014]
In the present invention, the carriage 10 is moved by using a hull moving vehicle described in Utility Model Registration No. 2533583, whose applicant is the right holder. This will be described with reference to FIG. 5. In FIG. 5A, the hull moving vehicle M includes a vehicle body 50, wheels 51 driven by an engine or a battery, and a handle 52. The vehicle body 50 rotates around a horizontal axis 53. A rotating arm 54 that moves is provided, and the rotating arm 54 can be moved up and down by a hydraulic cylinder 55 mounted in front of the vehicle body 50. A vertical shaft 56 is provided at the tip of the rotating arm, and a traction stand 57 is mounted on the vertical shaft 56 so as to be rotatable in the horizontal direction. A plurality of locking projections 57a are formed on the traction stand 57, and an upper locking portion 58 and a lower locking portion 59 are formed between the locking protrusions 57a.
[0015]
When the carriage 10 is moved, as shown in FIG. 5 (B), after inserting the traction stand 57 directly below the rear frame F of the frame member 10a of the carriage 10, the rotating arm 54 is raised to When F is engaged with the locking portion 59, the column 10c is lifted from the ground, and as a result, the carriage 10 can be moved following the movement of the hull moving vehicle M.
[0016]
In the present invention, in order to move the carriage 10 to an inclined surface or the like, the carriage 10 is specially improved. The conventional carriage has four wheels attached to the lower surface thereof. Therefore, when the carriage F moves from the locking portions 58 and 59 when the carriage is moved to an inclined surface or the like, the carriage 10 is In order to prevent this problem, the traction stand 57 and the frame member 10a are conventionally fixed with a chain or the like. However, the carriage 10 used in the present invention has a rear wheel on the column 10c. Since the change is made, when the frame F drops off from the locking portion 55c, the support 10c comes into contact with the ground, so that the cart 10 can be prevented from traveling.
[0017]
The operation of the hull lifting / lowering apparatus of the present invention having the above-described configuration will be described. When the hull B is lowered from the land to the sea, the bogie 10 carrying the hull B is moved from the storage location to the on-vehicle mounting table 9 by the hull moving vehicle M, and the bogie 10 is stopped at the position of the standing member 11. The hull moving vehicle M is pulled up. In this state, the passenger can go up to the boarding platform 21 from the stairs 23 (FIG. 4) and can easily board the hull B. Next, when the hoisting device 7 is operated and the wire rope 6 is loosened and the hull elevating device 1 is lowered along the rail 5, the hull elevating device 1 and the carriage 10 are as shown in FIGS. Sunk under the surface of the sea, eventually the hull B can sail away from the carriage 10 by buoyancy.
[0018]
When the hull B is withdrawn from the sea to the land, the hull moving vehicle M moves the empty carriage 10 from the storage location to the on-vehicle mounting base 9, stops the carriage 10 at the position of the standing member 11, and then winds up. The device 7 is operated, the wire rope 6 is loosened, the hull elevating device 1 is lowered along the rail 5 to a predetermined position, and is put on standby until the hull B arrives. Next, in a state where the hull B is navigated and approached on the carriage 10 of the hull lifting device 1, the occupant transfers to the boarding platform 21 and adjusts the position so that the hull B properly rides on the carriage 10. In this state, when the hoisting device 7 is operated and the wire rope 6 is wound to raise the hull elevating device 1 along the rail 5, the hull B is placed on the bogie 10 and the bogie is raised from the water surface. The carriage 10 carrying the hull B is moved to the storage location by the hull moving vehicle M.
[0019]
Accordingly, since the total weight of the hull B is applied to the rail 5, the large hull can be raised and lowered with low-cost equipment as compared with the conventional vertical lifting device, and the passenger on the hull side positions the hull. Therefore, it is possible to eliminate personnel on the marina side for raising and lowering the hull, and it is possible to easily get on and off the passenger from the boarding board 21 of the hull adjusting equipment 12.
