Transferring device using aero-levitation style
A transferring system using aero-levitation style and a transferring device using aero-levitation style are provided. The transferring device using aero-levitation style includes one or more pairs of caterpillars each of which moves while drawing a track; a plurality of air bearings disposed inside of the caterpillars and levitated from an inner bottom surfaces of the caterpillars by repulsive force of air; and a loading unit coupled to the air bearings onto which a portage is loaded, wherein the loading unit is levitated and moved together with the caterpillars by the movement of the caterpillars.
1. A transferring system using aero-levitation device, comprising:
an endless track section which moves while drawing a track;
a plurality of air bearings disposed inside of the endless track section and levitated from an inner bottom surface of the endless track section by repulsive force of air; and
a loading unit coupled to the air bearings onto which a portage is loaded, wherein
front and rear wheels for maintaining tension of the endless track section are respectively disposed at front and rear portions inside of the endless track section,
the loading unit is connected to the front and rear wheels through connecting shafts,
and the connecting shaft comprises a guide slot which is vertically formed in a portion where the connecting shaft is connected with the loading unit, and the loading unit comprises a guide protrusion which is formed on a position corresponding to the guide slot and guided in the guide slot.
2. The transferring system using aero-levitation device as claimed in claim 1 , wherein the endless track section comprises one or more pairs of caterpillars.
3. The transferring system using aero-levitation device as claimed in claim 2 , wherein an inner peripheral surface of the caterpillar is flat.
4. The transferring system using aero-levitation device as claimed in claim 2 , wherein a flat coating layer is formed on an inner peripheral surface of the caterpillar.
5. The transferring system using aero-levitation device as claimed in claim 4 , wherein the coating layer is formed of epoxy or urethane.
6. The transferring system using aero-levitation device as claimed in claim 1 , further comprising an air control unit for generating and controlling high pressure compressed air which is supplied to the air bearings.
7. The transferring system using aero-levitation device as claimed in claim 2 , further comprising a towing means for towing the loading unit.
8. The transferring system using aero-levitation device as claimed in claim 7 , wherein the towing means comprises a knob to be gripped by a worker.
9. The transferring system using aero-levitation device as claimed in claim 7 , wherein the towing means comprises a self-driven vehicle.
10. The transferring system using aero-levitation device as claimed in claim 2 , further comprising a driving unit for driving the caterpillars.
11. The transferring system using aero-levitation device as claimed in claim 10 , wherein the driving unit drives a selected pair of the front wheels or the rear wheels mounted to the caterpillars, or all the wheels.
12. The transferring system using aero-levitation device as claimed in claim 11 , wherein the driving unit comprises a driving shaft connected to the front wheels or the rear wheels and a power source providing power to the driving shaft.
13. The transferring system using aero-levitation device as claimed in claim 12 , wherein the power source comprises one or more motors or engines.
14. The transferring system using aero-levitation device as claimed in claim 12 , wherein the driving shaft comprises a first driving shaft and a second driving shaft connected to a selected pair of the front wheels or the rear wheels, and the first and second driving shafts are controllably driven by the power source, independently.
