Abstract

Provided is a cargo carrying vehicle including; an elevating table 2 elevatable in the vertical direction; a plurality of rotating bodies 31 located on the elevating table 2 and configured to rotate so as to carry a cargo C in a conveyance direction X that is a direction toward a loading-unloading part of an aircraft; and a support 32 configured to support the plurality of rotating bodies 31 , wherein the support 32 and the plurality of rotating bodies 31 constitute the conveying unit 3 , and the conveying unit 3 is movable on the elevating table 2 in a position adjusting direction Y that is a direction intersecting the vertical direction and the conveyance direction.

First claim

What is claimed is:

1. A cargo carrying vehicle capable of carrying cargo to a loading-unloading part provided in an object to be loaded with the cargo by being located adjacent to the loading-unloading part, the cargo carrying vehicle comprising:
an elevating table elevatable in the vertical direction and having an upper surface on which the cargo is carried;
first rotating bodies located on the elevating table and configured to rotate so as to carry the cargo on the elevating table in a conveyance direction that is a direction toward the loading-unloading part; and
a support frame configured to support the first rotating bodies, wherein
the support frame and the first rotating bodies constitute a conveying unit,
the conveying unit comprises second rotating bodies configured to move straight while rotating on the elevating table in a position adjusting direction that is a direction intersecting the vertical direction and the conveyance direction,
the first rotating bodies and the second rotating bodies are supported by the support frame, and
the conveying unit moves in the position adjusting direction relative to the elevating table to move the first rotating bodies in the position adjusting direction along the upper surface of the elevating table.

2. The cargo carrying vehicle according to claim 1 , further comprising:
a drive unit connected to the support frame and configured to generate a driving force to move the support frame in the position adjusting direction and to hold a position in the position adjusting direction of the support frame on the elevating table after the support frame is moved.

3. The cargo carrying vehicle according to claim 1 , further comprising:
a pair of guides opposed to each other in the position adjusting direction at a spacing larger than a width dimension of the cargo and arranged at positions opposed to lateral surfaces of the cargo located on the support frame.

4. The cargo carrying vehicle according to claim 1 , wherein
the elevating table comprises a ball mat in which a plurality of spheres supported rotatably around an entire circumference are arranged at the same height, and
upper end positions of the plurality of spheres of the ball mat are located lower than upper ends of the first rotating bodies.

5. The cargo carrying vehicle according to claim 1 , wherein
the position adjusting direction is a direction orthogonal to the vertical direction and the conveyance direction.

6. The cargo carrying vehicle according to claim 1 , wherein
the second rotating bodies comprise: horizontal axes rotating bodies each having a rotation axis in the horizontal direction; and vertical axes rotating bodies each having a rotation axis in the vertical direction, and
the first rotating bodies, the horizontal axes rotating bodies, and the vertical axes rotating bodies are supported by the support frame.

7. The cargo carrying vehicle according to claim 1 , wherein
the support frame comprises: a drive motor configured to drive the first rotating bodies; and a chain configured to transmit a driving force from the drive motor to the first rotating bodies.

8. The cargo carrying vehicle according to claim 2 , wherein
the drive unit comprises an oil pressure cylinder.

9. The cargo carrying vehicle according to claim 1 , comprising a plurality of elevating tables elevatable in the vertical direction, the plurality of elevating tables being elevatable independently of each other, wherein
out of the plurality of elevating tables, an elevating table closest to the loading-unloading part comprises the conveying unit.

10. The cargo carrying vehicle according to claim 1 , wherein
conveying rollers or carrying tires project on an upper surface of the elevating table at a position closer to the loading-unloading part than the conveying unit.

11. The cargo carrying vehicle according to claim 1 , wherein the support frame has a single layer framework.

12. A cargo carrying vehicle capable of carrying cargo to a loading-unloading part provided in an object to be loaded with the cargo by being located adjacent to the loading-unloading part, the cargo carrying vehicle comprising:
an elevating table elevatable in the vertical direction;
first rotating bodies located on the elevating table and configured to rotate so as to carry the cargo on the elevating table in a conveyance direction that is a direction toward the loading-unloading part; and
a support frame configured to support the first rotating bodies, wherein
the support frame and the first rotating bodies constitute a conveying unit,
the conveying unit comprises second rotating bodies configured to move straight while rotating on the elevating table in a position adjusting direction that is a direction intersecting the vertical direction and the conveyance direction,
the first rotating bodies and the second rotating bodies are supported by the support frame, and
the conveying unit moves in the position adjusting direction relative to the elevating table to move the cargo in the position adjusting direction.
