Description

Technical Field [0001] The present invention relates to a hydraulic rotor-operated boat lifting or immersion boat lift apparatus in which gears are embedded in a buoyancy tank,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hydraulic rotor-operated boat lifting or immersion boat lift apparatus in which a hydraulic rotor assembly is embedded in a buoyancy tank and lifting or surfacing a motor boat, a rubber boat, a fishing boat,

Generally, when the hull is anchored, the water hits the outer surface of the hull due to the swelling of the water due to waves and the like, so that the outer surface of the hull can be physically damaged.

In addition, more than 600 species of marine creatures, including shellfish, mussels, and oysters, are attached to the submerged part of the hull when the vessel is operated for a long period of time or when the hull has been immersed in water, especially in seawater for many years. When such marine life attaches to the hull, serious problems arise, such as a decrease in the speed of operation of the ship due to friction with the sea surface, resulting in a doubling of the fuel cost. In order to prevent the attachment of marine organisms, antifouling paints are coated on flooded parts of ships. Most of antifouling paints are used by IMO (International Maritime Organization) because of environmental pollution such as toxicity to marine life. Is regulated. Although antifouling paints with low toxicity have been developed, their useful lives are limited and various problems associated with antifouling painting work arise.

Accordingly, it is usually necessary to physically remove marine life attached to the flooded surface of the hull at a period of 2 to 6 months, and to incur considerable expense.

In order to solve or alleviate the above problems, it is necessary to prevent the attachment of marine life by putting the vessel on the water surface when the marine vessel is not docked for a long time, and to dismantle the marine life already attached. Thus, various lift devices have been developed for lifting the ship in the air above the water surface. However, most of the lift devices are installed on the platform or installed in the water, which is ineffective due to corrosion problems, fluctuations in the height of the water due to the tide interval, and so on.

In order to solve such a problem, U.S. Patent No. 6,823,809 describes a ship lifting apparatus and method floating on a water surface. However, in this patent, when the vessel is lifted completely above the water surface, the lower portion of the lifting assembly is corroded to the water surface to deteriorate durability, and the connecting portion of the float and the lifting assembly, which receives loads of the ship and the lifting assembly, And is also less durable due to abrasive friction, and also because the roller bearing the load of the ship and the lifting device during the lifting of the buoyancy tank from above the water surface is completely separated from the buoyancy tank, Because it is operated only by the lift arm crossbeams, the buoyancy tank is in an unstable state where it shakes so much that it does not come up smoothly and smoothly on the surface of the water.

In addition, since the ship's lifting device of the patent is always in a submerged condition of the hydraulic cylinder, the hydraulic cylinder hose, and the lifting assembly regardless of whether the ship is lifted or flooded above the water surface, the apparatus as well as the hydraulic fluid Which causes environmental pollution problems.

The present inventor has filed a series of patents relating to a boat lifting apparatus for lifting or submerging a ship in order to solve the above problems.

The pin of the solenoid locking means 40 is inserted into the hole 22a of the main gear 22 while the ship is lifted.

2-11, the operation of submerging a vessel raised above the water surface 34 into water and the operation of flooding a vessel immersed in water in the air above the water surface 34 are performed in a pair of buoyancy tanks 30 The left buoyancy tank 30 will be mainly described.

In FIG. 2, the mounted ship is fully in the air above the water surface 34, and the buoyancy tank 30 is fully immersed. In order to immerse the ship on the water surface, the hydraulic rotor 21 is first rotated a little, and then the solenoid locking means 40 is energized to release the locking means 40. 5), the power is sequentially transmitted to the main gear 22, the idle gear 23, and the sector gear 24 (see FIG. 5) Causing the arm 26 to rotate and consequently causing the buoyancy tank 30 to rise above the water surface 34. At this time, when the idle gear 23 is rotated 90 degrees, the gear module is set so that the sector gear 24 rotates 45 degrees, and the gear module is inserted through the hole 25a of the bracket 25 and the hole 26b of the arm 26 So that the buoyancy tank 30 is raised above the water surface 34 with the shaft 21a serving as a rotation center. The hydraulic rotor 21 continues to operate and the arm 26 rotates 180 degrees until the mounted ship is completely floated on the water surface 34 itself (see Fig. 11). The vessel then exits the lift device of the present invention.

The following describes the operation in which the vessel flooded in water is completely floated in the air above the surface of the water (34). In order to completely lift (lift) the ship completely in the air above the water surface, the ship is guided into the floatated lifting assembly 10 with the buoyancy tincture 30 floating sufficiently above the water surface, 5), the lift assembly 10 is gradually raised above the water surface 34. [0050] As shown in FIG. The manner in which the ship is lifted completely over the surface 34 is the reverse of the method for submerging the ship on the surface of the water. The solenoid pin, which is the locking means 40 acting as a safety pin, cuts off the power to the solenoid of the locking means 40, As shown in Fig.

As shown in Figs. 7 to 11, when the ship is raised or lowered by the lifting device, no part of the buoyancy tank 30 is configured to touch the berth wall 35 when the buoyancy tank 30 rotates.

It will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
