Abstract

A portable mast assembly is comprised of a skid assembly having a horizontally oriented frame comprised of longitudinally extending support beams and a mast assembly having at least two vertically extending columns that are supported directly upon a longitudinally extending mast beam without an intervening track or roller. A means for moving the mast beams along the top of the extending support beams of the frame without a roller is provided.

Claims

1. A portable mast assembly comprising:

(a) a skid assembly, said skid assembly having a horizontally oriented frame, said frame having at least two longitudinally extending support beams;

(b) a mast assembly, said mast assembly having at least two longitudinally extending mast beams, each mast beam supporting a vertically extending column, each said longitudinally extending mast beam positioned and supported directly upon one of said longitudinally extending support beams of said frame without an intervening roller; and

(c) means for moving said mast beams along the top of said support beams of said frame.

2. The portable mast assembly recited in claim 1 further comprising a guide for slidably retaining said mast beams upon said support beams of said frame.

3. The portable assembly recited in claim 2 wherein said means for moving said mast beams along the top of said support beams of said frame includes horizontally oriented actuators having an extendible and retractable rod.

4. The portable assembly recited in claim 3 wherein said vertical columns of said mast assembly are vertically extendable and retractable.

5. The portable mast assembly recited in claim 4 further comprising a deck surface on said skid assembly.

6. The portable mast assembly recited in claim 5 wherein said deck surface has an opening to provide access below said deck surface of said skid assembly.

7. The portable mast assembly recited in claim 6 wherein said opening in said deck surface is covered by pivotally mounted doors.

8. The portable mast assembly recited in claim 7 wherein said vertically extendable and retractable mast columns are comprised of:

(a) a lower tubular column segment;

(b) an upper tubular column segment, said upper tubular column segment slidably positioned within said lower tubular column segment; and

(c) a vertically oriented actuator having an extendible and retractable rod mounted within each said lower tubular column, said extendible and retractable rod of said vertically oriented actuator being pivotally mounted to said upper tubular column segment.

9. The portable mast assembly recited in claim 8 further comprising:

(a) a vertically extending stiff leg mounted on the outside of each said upper column segment, each said stiff leg having a plurality of spaced apart selective stiff leg holes extending along the length of each said stiff leg;

(b) a stiff leg support bracket mounted on each said lower column segment, said stiff leg support bracket having a bracket hole configured to correspond with a selected hole on said stiff leg; and

(c) a support pin configured to be received in each said bracket bole and said selected hole on said stiff leg Whereby each said upper column segment and each said corresponding lower column segment is supported in a desired configuration.

10. The portable mast assembly recited in claim 9 further comprising a transverse mast support beam, said mast support beam spanning between said vertically extending columns.

11. The portable mast assembly recited in claim 10 wherein said guide for slidably retaining said mast beams upon said support beams of said frame is comprised of stacked overlapping plates.

12. The portable mast assembly recited in claim 11 further comprising a bearing assembly at the top of each said vertical column.

13. A portable mast assembly comprising:

(a) a horizontally oriented frame, said frame having at least two longitudinally extending support beams;

(b) at least two longitudinally extending mast beams, each said longitudinally extending mast beam being positioned and supported directly upon one of said longitudinally extending support beams of said frame without an intervening roller;

(c) a vertically extendable and retractable column supported upon each said longitudinally extending mast beam;

(d) at least one horizontally oriented actuator having an extendible and retractable rod whereby extension and retraction of said rod will move said mast beams along said top of said frame support beams; and

(e) at least two vertically oriented actuators, each said actuator having an extendible and retractable rod whereby extension and retraction of said extendible and retractable rods extends and retracts said columns.

14. The portable mast assembly recited in claim 13 wherein each said column has an upper segment and a corresponding lower segment, further comprising:

(a) a vertically extending stiff leg mounted on the outside of each said upper column segment, each said stiff leg having a plurality of spaced apart selective stiff leg holes extending along the length of each said stiff leg;

(b) a stiff leg support bracket mounted on each said lower column segment, said stiff leg support bracket having a bracket hole configured to correspond with a selected hole on said stiff leg; and

(c) a support pm configured to be received in each said bracket hole and said selected hole on said stiff leg whereby each said upper column segment and each said corresponding lower column segment is supported in a desired configuration.

15. The portable mast assembly recited in claim 14 further comprising a guide for slidably retaining said mast beams upon said support beams of said frame.

16. The portable mast assembly recited in claim 15 further comprising:

(a) a deck surface on said frame, said deck surface having an opening to provide access below said deck surface;

(b) doors over said opening, said doors pivotally mounted on said frame; and

(c) a mast support beam spanning between said vertically extendable and retractable columns.

17. The portable mast assembly recited in claim 16 wherein said guide is comprised of:

(a) a longitudinally extending bottom plate; and

(b) an overlapping top plate mounted to said bottom plate, said top plate extending over a segment of each said mast support beam.

18. The portable mast assembly recited in claim 13 wherein said vertically oriented actuators provide a downward force of at least 15 tons.

19. A portable mast assembly comprising:

(a) a skid assembly, said skid assembly having a horizontally oriented frame, said frame having longitudinally extending support beams, said support beams having a top surface;

(b) a mast assembly, said mast assembly having at least two vertically extendable and retractable columns, each of said vertically extendable and retractable columns supported on a corresponding longitudinally extending mast beam, each said longitudinally extending mast beam positioned upon and supported by said top surface of one of said longitudinally extending support beams of said frame without an intervening roller and track; and

(c) at least one horizontally oriented actuator, said actuator having an extendible and retractable rod, said horizontally oriented actuator mounted between said skid assembly and said mast assembly whereby extension and retraction of said rod of horizontally oriented actuator will slide said mast beams of said mast assembly directly upon and along said top surface of said longitudinally extending support beams of said frame without an intervening roller and track.

20. The portable mast assembly recited in claim 19 further comprising:

(a) a decking surface supported on said frame of said skid assembly wherein said deck surface has an opening providing access below said deck surface of said skid assembly and whereby extension and retraction of said rod of said horizontally oriented actuator will slide said mast beams directly upon and along said top surface of said support beams of said frame of said skid assembly for alignment with said deck surface opening;
