Abstract
The utility model relates to a pontoon hoisting device which comprises a pontoon, a deep water pump, winding engines, power lines and a water discharging pipe. The utility model is characterized in that the deep water pump is arranged in the pontoon, the winding engines are arranged at both ends outside the pontoon, the water discharging pipe is connected with the deep water pump and the bottom surface of the pontoon is provided with a water inlet for automatic controlling the opening and the closing of the pontoon. The pontoon of the pontoon hoisting device is dragged to sink, and then water in the pontoon is discharged to cause the pontoon to produce buoyancy, and thus, a sunken ship can be lifted. When the utility model is used for salvaging sunken ships, the hoisting force is big, which is especially suitable for salvaging large-tonnage sunken ships.
Description
Technical field
The utility model relates to a kind of wreck salvage device, particularly a kind of raising with salvage pontoons device that adopts the floating drum lifting.
Background technology
At present, the Refloatation method of shipwreck adopts a machinery hanging or inflation to go up floating more in rivers and the ocean.Provide a kind of device of salvaging a sunken ship with the air bag drainage as Chinese patent 91105115.5, promptly the cabin of putting into shipwreck with rubbery air pocket puts on the air to it water of cabin is discharged, thereby shipwreck is floated.Rubbery air pocket is simple in structure, and the surface sees that this is a kind of convenience, safety, labour-saving device, but it is undesirable to salvage effect, especially can't pick up the large-tonnage shipwreck, its reason be rubber bag bear pressure and inflation is limited.And therefore a machinery hanging must also can't salvage the large-tonnage shipwreck by deep water based on the salvor.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of floating drum hoisting device, utilizes this floating drum hoisting device can conveniently salvage the large-tonnage shipwreck.
For solving the problems of the technologies described above, floating drum hoisting device of the present utility model comprises power lead, drain hose and the air inlet pipe of floating drum, sinking pump, winch, sinking pump, the sinking pump setting is installed in the floating drum, a volume machine setting is installed in the outer two ends of floating drum, drain hose is connected with sinking pump, and the floating drum bottom surface is provided with the water inlet that electronic its opening and closing of control are installed.
This floating drum hoisting device is sunk in the shipwreck water, hang shipwreck, discharge the water in the floating drum, shipwreck rises with floating drum, thereby solves large-tonnage wreck salvage problem.
As a kind of improvement of the present utility model, central authorities are provided with dividing plate at floating drum, and dividing plate is separated into two not connected chambers with floating drum.After adopting this structure, the easy adjusted control of floating drum two ends balance.
As another kind of improvement the of the present utility model, floating drum is " mouth " font head and the tail interconnection system structure.After adopting this structure, can improve the crane capacity of floating drum hoisting device greatly.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is the cutaway view of the utility model floating drum hoisting device.
Fig. 2 is the birds-eye view of the utility model floating drum hoisting device.
Fig. 3 is the view of salvaging a sunken ship of the utility model floating drum hoisting device.
The specific embodiment
By Fig. 1, Fig. 2 as can be known, this floating drum hoisting device, mainly comprise floating drum 3, sinking pump 2, winch 1, sinking pump power lead 5, drain hose 4 and air inlet pipe 10, floating drum 3 is " mouth " font head and the tail interconnection system structure, floating drum 3 central authorities are provided with dividing plate 6, dividing plate 6 is separated into two not connected chambers with floating drum, it is indoor that sinking pump 2 is provided with two of being installed in floating drum 3 respectively, lifting winch 1 is symmetrical arranged the two ends that are installed in outside the floating drum 3, drain hose 4 is connected with sinking pump 2, the bottom surface, two chambers of floating drum 3 is provided with respectively and automatic guidance is installed it is opened, the water inlet 9 that closes, floating drum 3 bottom periphery settings are equipped with load hook 8, are used to lift by crane shipwreck.
Principle of work: referring to Fig. 3, after being dragged to the shipwreck 12 position waters surface with barge ship 11 floating drum hoisting device, open water inlet 9, water enters floating drum 3, be in suspended state to floating drum 3, closed water inlet 9 stops into water, and winch hoist cable 7 lower ends, two ends are linked to each other with shipwreck head and the tail two ends, starts winch 1, it is heavy that floating drum 3 is dragged by shipwreck 12 location, but still be in suspended state, and start sinking pump 2, the water in the floating drum 3 is discharged, water in floating drum 3 constantly is discharged from the process, the buoyancy of floating drum 3 is increasing, and shipwreck raises up the most at last, at this moment can utilize barge ship 11 that floating drum hoisting device and shipwreck 12 are moved in water on the dock of repairing yard together.
