Abstract

The hydraulic transportation apparatus and method of the present invention incorporate a multiple chamber framework internally disposed preferably within at least one single shaft structure, which facilitates movement of object transport containers within the multiple chamber framework. Preferably, fluid elevation is employed to elevate and lower object transport containers and their contents within the multiple chamber framework. Each single shaft structure may be constructed from an existing rehabilitated shaft, or a newly drilled shaft. The present invention may be utilized in vertical or incline lifting environments, and an auxiliary hoist chamber may be incorporated into the multiple chamber framework for use as an alternative to, or in conjunction with, elevating objects by employing fluid elevation. The present invention may be employed in a variety of heavy lifting scenarios, including underground mining or in above ground lifting environments.

Claims

1. An apparatus configured for bidirectionally conveying objects comprising:

a transport container containing one or more objects; and

a transportation chamber having upper and lower outlets for transporting the transport container in a chamber liquid internally disposed within the transportation chamber,

wherein the apparatus is configured to elevate the transport container to the upper outlet by flotation and lower to the lower outlet the transport container by sinking in the chamber liquid to convey objects,

wherein the transport container is airtight to allow the transport container to elevate by floatation in the chamber liquid,

wherein said lower outlet is under said upper outlet and comprises an airlock to control ingress into, and egress from, the transport chamber.

2. The apparatus of claim 1, further comprising a loader for loading objects into the transport container.

3. The apparatus of claim 2, wherein the loader is operatively engaged with the transportation chamber and comprises an object storage and a channel configured to transfer objects from the storage through the channel into the transport container.

4. The apparatus of claim 3, further comprising a guiding device configured to guide the transport container.

5. The apparatus of claim 4, wherein the guiding device is horizontally disposed within a bottom portion of a conveyor in operative communication with the transportation chamber and the transport container.

6. The apparatus of claim 1, further comprising an auxiliary chamber laterally disposed to the transportation chamber for transporting objects.

7. The apparatus of claim 1, wherein the transportation chamber comprises a vertically disposed cavity.

8. The apparatus of claim 1, further comprising a fluid controller internally disposed within the transportation chamber and configured to control an amount of the chamber liquid in the transportation chamber to elevate and lower the transport container within the transportation chamber.

9. The apparatus of claim 8, wherein the fluid controller comprises a lower chamber internally disposed within the transportation chamber, and a valve configured to control the amount of the chamber liquid in the lower chamber.

10. The apparatus of claim 1, wherein the transport container comprises a moveable lid configured to seal the transport container.

11. The apparatus of claim 1, further comprising a first location device operatively connected with the transportation container and configured to communicate location information of the transport container between the first location device and a second location device.

12. A method for bidirectionally transporting objects comprising:

providing a transport container;

loading the transport container with one or more objects;

elevating the transport container containing the one or more objects in a chamber liquid internally disposed within a transportation chamber having upper and lower outlets, wherein the transport container is airtight to allow the transport container to elevate to the upper outlet by floatation in the chamber liquid;

unloading the transport container; and

lowering the transport container by sinking the transport container in the chamber liquid within the transportation chamber to the lower outlet,

wherein said lower outlet is under said upper outlet and comprises an airlock to control ingress into, and egress from, the transport chamber.

13. The method of claim 12, further comprising loading objects into the transport container using a loader.

14. The method of claim 13, wherein the loader operatively engaged with the transportation chamber and comprises an object storage and a channel configured to transfer objects from the storage through the channel into the transport container.

15. The method of claim 14, further comprising guiding the transport container using a guiding device.

16. The method of claim 15, wherein the guiding device is horizontally disposed within a bottom portion of a conveyor in operative communication with the transportation chamber and the transport container.

17. The method of claim 12, wherein the transportation chamber comprises a vertically disposed cavity.

18. The method of claim 12, further comprising controlling an amount of the chamber liquid in the transportation chamber using a fluid controller operatively associated with the transportation chamber.

19. The method of claim 18, wherein the fluid controller comprises a lower chamber internally disposed within the transportation chamber, and a valve configured to control the amount of the chamber liquid in the lower chamber.

20. The method of claim 12, wherein the transport container comprises a moveable lid configured to seal the transport container.

21. The method of claim 12, further comprising communicating, using a first location device operatively connected with the transportation container, location information of the transport container between the first location device and a second location device.

22. An apparatus configured for bidirectionally conveying objects comprising:

a transport container containing one or more objects;

a delivery chamber having an upper and lower outlets for elevating the transport container from the lower outlet to the upper outlet by flotation in a first chamber liquid internally disposed within the delivery chamber, wherein the transport container is airtight to allow the transport container to elevate by floatation in the first chamber liquid; and

a return chamber for lowering the transport container by sinking in a second chamber liquid internally disposed within the return chamber,

wherein said lower outlet is under said upper outlet and comprises an airlock to control ingress into, and egress from, the delivery chamber.

23. The apparatus of claim 22, wherein the return chamber further comprises a control gate to regulate a downward movement of the transport container within the return chamber.

24. The apparatus of claim 22, further comprising a loader for loading objects into the transport container.

25. The apparatus of claim 24, wherein the loader is operatively engaged with the return chamber and comprises an object storage and a channel configured to transfer objects from the storage through the channel into the transport container.

26. The apparatus of claim 25, further comprising a guiding device configured to guide the transport container.

27. The apparatus of claim 26, wherein the guiding device is horizontally disposed within a bottom portion of a conveyor in operative communication with the return chamber, the transport container, and the delivery chamber.

28. The apparatus of claim 22, further comprising an auxiliary chamber laterally disposed to the delivery chamber or the return chamber.

29. The apparatus of claim 22, wherein the return chamber comprises a vertically disposed cavity.

30. The apparatus of claim 22, further comprising a delivery device comprising a cavity laterally disposed to the return chamber, wherein the delivery device is configured to receive the transport container from the return chamber and wherein the delivery device is equipped to facilitate elevation of the transport container into the delivery chamber.
