The present invention relates to a new apparatus and method for use in subterranean exploration. The present invention provides a rapid rig-up and rig-down of a drill floor mounted device such as a pipe racking system. In particular, the present invention discloses a system and method for rapid deployment of a drill floor mounted pipe racking system that is capable of being retrofit to an existing drilling rig.

The present invention discloses a high-capacity drilling rig system that includes novel design features that alone and more particularly in combination facilitate a fast rig-up and rig-down with a single set of raising cylinders and maintains transportability features. In particular, a transport trailer is disclosed having a first support member and a drive member which align the lower mast portion with inclined rig floor ramps and translate the lower mast legs up the ramps and into alignment for connection. A pair of wing brackets is pivotally deployed from within the lower mast width for connection to the raising cylinder for raising the mast from a horizontal position into a vertical position. A cantilever is pivotally deployed from beneath the rig floor to a position above it for connection to the raising cylinder for raising the substructure from a collapsed position into the erect position.

The present invention discloses a drill rig relocation system. Lift frames are provided as add-ons to existing drill rigs, or as integral openings within the length of the base boxes. A lift cylinder and bearing mat assembly is connected beneath the lift frame or base boxes. Each bearing mat assembly has a slew drive for controlled directional rotation. A torque arrest system allows vertical movement of the torque reaction point as the substructure is elevated to control the orientation and magnitude of forces. In one embodiment, the drill rig is supported on linear sleeve bearings slideably mounted in the bearing mat assemblies. Translation cylinders on the bearing mats expand to move the drill rig by translating the linear sleeve bearings along the shafts.

The present invention relates to a mechanically steered articulating dolly transport system for transporting large structures such as a drilling mast over the federal highway system. Generally, the invention relates to an articulating dolly system that utilizes a unique mechanical system for steering a first dolly with a path generated by the movement of the load held by the second dolly. More particularly, the invention provides a front dolly steered by a non-rotatable front steering frame, a rear dolly having a pivotally mounted turntable and a pair of steering links connected between the respective sides of the front steering frame and the turntable. The left steering link and the right steering link are located in a first plane. One or both of the turntable and the steering frame being located on a second plane that is not the first plane. Moment forces generated between plane one and plane two elastically deform one or both of the steering frame and the turntable to permit the transport system to make a left-hand or right-hand turn.

A pipe handling apparatus has a frame, a boom pivotally connected to the frame so as to be movable between a first position and a second position, an arm extending outwardly of the boom when the boom is in the second position, a gripper affixed to the end of the arm opposite the boom, a first line having a first end affixed to the boom, a second line interconnected to an opposite end of the first line and connected to the frame, and an actuator interconnected to the first and second lines. The actuator changes an angular relationship of the first and second lines so as to selectively tension the lines. The second line includes a first cable offset from linear alignment with the first line and a second cable extending in angular relationship with the first cable.

Exemplary embodiments provide a rotary misalignment-compensation bushing connection system that may be used in large-scale operations where several components are mounted in alignment on a single pin. For example, the misalignment-compensation system may be used in preloaded connection of a male lug rotatably mounted between a first lug and a second lug, on heavy equipment, for example, oil field exploration and production equipment. The misalignment-compensation system includes tapered cone bushings and surrounding counter-tapered cup bushings that expand in diameter and align the connection system as it is torqued together assembling the components to the pin.

The present invention discloses a drill rig relocation system. Lift frames are provided at opposite ends of a base box of a drill rig substructure. A lift cylinder and bearing mat assembly are rotatably connected beneath the lift frame. The bearing mat assemblies may be rotated to the desired direction for moving the drill rig. The lift cylinders are then expanded, placing the bearing mat assemblies onto the ground and lifting the base boxes and drill rig off the ground. The drill rig is supported on linear sleeve bearings slideably mounted in the bearing mat assemblies. Translation cylinders on the bearing mats expanded to move the rig by translating the linear sleeve bearings along the shafts. After the lift cylinder expands to place the bearing mat on the ground, the translation cylinders are retracted, providing the linear bearing with the full length of the shaft for the next movement.
