ABSTRACT:
An improved oil well drilling rig structure (10) is provided. The drilling rig structure (10) includes a base (32) for placement on the ground at a well site. The base (32) includes first and second ends (32a, 32b). A drill floor (14) supported on a floor box (12) having first and second ends (12a, 12b) is disposed parallel to and adjacent the first end (32a) of the base (32). The floor box (12) is coupled to the base (32) by spaced apart parallel legs (76, 78) each pivotally attached between the upper box (12) and the base (32) for elevating the floor (14) from a low position adjacent to the first end (32a) of the base (32) to an elevated position medially between the ends (32a, 32b) of the base (32) and located above the base (32) by rotation of the legs (76, 78) towards a vertical position. The structure (10) further includes a tensile link (40) having first and second ends (40a, 40b). The first end (40a) of the tensile link (40) is coupled adjacent the second end (12b) of the floor box (12) opposite the first end (32a) of the base (32). A thrust link (42) is provided having first and second ends (42a, 42b). The first end (42a) of the thrust link (42) is coupled adjacent to the second end (40b) of the tensile link (40). The second end (42b) of the thrust link (42) is pivotally coupled adjacent the second end (32b) of the base (32). Power driving structure (60) is connected to the base (32) and the links (40, 42) for drawing the second end (40a) of the tensile link (40) to a pin linkage position on the base (32) adjacent the second end (32b) of the base (32) as the legs (76, 78) approach the vertical position.
