Abstract

A mobile oilfield material transfer unit includes a chassis having a gooseneck and support base, the support base including a first portion and second portion, and the chassis further comprising a rear axle suspension system coupled with at least two wheels for movably supporting the chassis. The mobile oilfield material transfer unit further includes an erecting mast assembly having a mast movably connected with the chassis proximate to the second portion, and an actuator system coupled with the mast and with the chassis for moving the mast between a horizontal position and a vertical position. At least two vertical conveyor assemblies may be coupled with the erecting mast and moveable between the horizontal position and the vertical position, and at least two horizontal conveyor systems may be coupled with the support frame and engageable with the at least two vertical conveyor assemblies. Each of the at least two horizontal conveyor systems may have a horizontal section with an inlet and an inclinable section with a discharge chute. Also, each of the at least two horizontal conveyor systems may be adapted to move a volume of oilfield material from the inlet to the discharge chute.

First claim

What is claimed is:

1. A mobile oilfield material transfer unit, comprising:
a chassis having a gooseneck and support base, the gooseneck generally coplanar with the support base when in a ramp configuration to facilitate oilfield material transport to the support base, the chassis further including a first end, a second end, at least one support beam extending between the first end and the second end, and the chassis further comprising a rear axle suspension system coupled with the at least one support beam for movably supporting the at least one support beam, wherein the at least one support beam further comprises a first support beam and a second support beam extending between the first end and the second end and being separated by a gap;
an erecting mast assembly including a mast movably connected with the chassis proximate to the second end, and an actuator system coupled with the mast and with the chassis for moving the mast between a horizontal position and a vertical position adjacent a silo;
a first conveyor assembly including a support frame coupled with the mast and moveable between the horizontal position and the vertical position, the first conveyor assembly including a first conveyor coupled with the support frame, an inlet, and an upper discharge portion, the first conveyor adapted to move a volume of oilfield material from the inlet to the upper discharge portion, wherein the support frame further comprises one or more silo-engaging members shaped to connect with a predetermined portion of the silo when the support frame and the mast have been moved to the vertical position adjacent the silo; and
a second conveyor system including a second conveyor having a horizontal section with an inlet and an inclinable section pivotably connected to the horizontal section and configured to move a volume of oilfield material toward the inlet of the first conveyor assembly when the support frame and the mast are moved to the vertical position, wherein the second conveyor system is at least partially positioned in the gap.

2. The mobile oilfield material transfer unit of claim 1 , wherein the inlet of the first conveyor assembly is below and proximate to a discharge of the inclinable section of the second conveyor system.

3. The mobile oilfield material transfer unit of claim 1 , wherein the first conveyor assembly further comprises a discharge chute coupled with the upper discharge portion of the first conveyor assembly.

4. The mobile oilfield material transfer unit of claim 3 , wherein the discharge chute comprises a first outlet and a second outlet and a diverter valve for selectively directing the volume of oilfield material though at least one of the first and second outlet.

5. The mobile oilfield material transfer unit of claim 1 , wherein the first conveyor assembly further comprises a pivoting conveyor assembly movably associated with the upper discharge portion.

6. The mobile oilfield material transfer unit of claim 5 , wherein the support frame is movably coupled with the mast and further comprises at least one actuator for moving the support frame relative to the mast.

7. The mobile oilfield material transfer unit of claim 1 , wherein the rear axle suspension system is a collapsible suspension system.

8. The mobile oilfield material transfer unit of claim 1 , wherein the second conveyor system is configured to be folded into a stowed position when the support frame and the mast are moved to the horizontal position.

9. A mobile oilfield material transfer unit, comprising:
a chassis having a gooseneck and a support base, the support base including a first portion and a second portion, the gooseneck generally coplanar with the support base when in a ramp configuration to facilitate oilfield material transport to the support base, and the chassis further comprising a rear axle suspension system coupled with at least two wheels for movably supporting the chassis;
an erecting mast assembly including a mast movably connected with the chassis proximate to the second portion, and an actuator system coupled with the mast and with the chassis for moving the mast between a horizontal position and a vertical position adjacent a silo;
at least two vertical conveyor assemblies coupled with the erecting mast assembly and moveable between the horizontal position and the vertical position, wherein each of the at least two vertical conveyor assemblies comprises a discharge chute configured to be disposed adjacent the silo; and
at least two horizontal conveyor systems coupled with the support base and engageable with the at least two vertical conveyor assemblies, each of the at least two horizontal conveyor systems having a horizontal section with an inlet and an inclinable section pivotably connected to the horizontal section and configured to move a volume of oilfield material toward an inlet hopper of each of the at least two vertical conveyor assemblies when the mast is moved into the vertical position.

10. The mobile oilfield material transfer unit of claim 9 , wherein the chassis comprises a central box beam structure and two outer beam rails, and wherein the central box beam structure is separated by a gap from each of the two outer beam rails.

11. The mobile oilfield material transfer unit of claim 10 , wherein the central box beam structure and the two outer beam rails extend across the second portion, the first portion, and the gooseneck.

12. The mobile oilfield material transfer unit of claim 10 , wherein each of the at least two horizontal conveyor systems is at least partially positioned in the gap formed between the central box beam structure and each of the two outer beam rails.

13. The mobile oilfield material transfer unit of claim 9 , wherein each inclinable section comprises a telescoping neck.

14. The mobile oilfield material transfer unit of claim 9 , further comprising an access deck disposed upon the support base and at least one ramp movably connected with a perimeter side of the access deck.

15. The mobile oilfield material transfer unit of claim 9 , wherein each of the at least two vertical conveyor assemblies further comprises a bucket elevator, and a bucket elevator head.

16. The mobile oilfield material transfer unit of claim 15 , wherein each of the at least two vertical conveyor assemblies further comprises an auger conveyor disposed proximate the bucket elevator head and in communication with the bucket elevator, the auger conveyor further comprising at least one opening configured to deliver oilfield materials to a receiving chute of the silo.

17. The mobile oilfield material transfer unit of claim 9 , wherein the rear axle suspension system is a collapsible suspension system.

18. The mobile oilfield material transfer unit of claim 17 , wherein the second portion is configured to couple with at least one extended base of a support frame for supporting the at least two vertical conveyor assemblies in the vertical position.

19. The mobile oilfield material transfer unit of claim 9 , wherein the at least two horizontal conveyor systems are configured to be folded into a stowed position when the mast is moved to the horizontal position.
