  • Fast moving drilling rig
    Patent number: 7765749
    Abstract: A method and apparatus for transporting and assembling a drilling rig is disclosed. The drilling rig of a preferred embodiment of the present invention utilizes specialized positioning pads integral to the side boxes of the drilling rig to facilitate the connection of the center drill floor of the drilling rig to the side boxes of the rig. A preferred embodiment of the present invention may also utilize a specialized positioning dolly and an adjustable fifth-wheel truck connection for transporting the mast to the drill site, assembling the mast sections together, and positioning the mast for connection to the drill floor of the rig. The result is a unique drilling rig design and sequence for assembly that significantly reduces the time required to transport the rig from location to location and to assemble the rig at the drill site.

  • Structural connector for a drilling rig substructure
    Publication number: 20070011984
    Abstract: A method and apparatus for connecting sections of a drilling rig substructure is disclosed. The disclosed invention is a unique structural connector in which sections of a drilling rig substructure can be connected together without the use of pins or pin-type connectors. The structural connector of the present invention utilizes specially-shaped fixed members connected to, and extending through, support plates that are attached to sections of a drilling rig substructure that mate with specially-shaped mating lugs that are mounted on mating lug plates that are attached to separate sections of the drilling rig substructure. When the sections of the drilling rig substructure to be connected are positioned together, the specially-shaped mating lugs engage the specially-shaped fixed members and form a high strength structural connection between the sections of the drilling rig substructure.
