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 relates to a positioning system for service lines. Generally, the invention relates to a mechanism for the deployment, retraction, and transportation of fixed-length service lines such as electrical, pneumatic, hydraulic, and communication resources necessary to the operation of a drilling rig used for subterranean exploration. More particularly, the invention provides an extendable cable positioning system for use with drilling rigs where pad drilling will require relatively short distance movements of the drilling rig, and it is desirable to leave the energy resource systems stationary.

The present invention relates to a tension link drill floor level connection system for use on a drilling rig, as may be used in subterranean exploration. The present invention provides a tension link assembly for resisting separating forces incurred between sections of the substructure. In particular, the tension link assembly may be located at the drill floor level for resisting the separating forces imparted by “splayed” or wide leg mast structures that tend to separate substructure side boxes from the substructure center section. The present invention may be comprised of a first link element and a second link element with a tension link being connectable over the first and second link elements to resist separation between sections of the substructure. A latch mechanism may be utilized to prevent upward movement of the tension side boxes or center section relative to the drill floor or to one another.

A blowout preventer (BOP) lifting apparatus has a reinforced frame and a gate for securing a BOP stack. The frame has a central U-shaped recess for securing a collared portion of the BOP stack. The gate pivotally swings between a closed position on the frame and an open position for installation and removal of the lifting apparatus from the BOP stack. An actuator has a first end connected to a top surface of the frame and a second end connected to the gate for actuating the opening and closing of the gate to the frame. When the gate is in the closed position, three locking pins are inserted into three vertical pinning holes located on the frame, which are aligned with three pinning holes located on the gate. The apparatus may be lifted via cables or other lifting mechanisms attached via lifting eyelets located on each corner of the frame.

The present invention provides a rapid rig-up and rig-down pipe stand building and racking system that is capable of being retrofit to an existing drilling rig. In particular, the invention relates to a horizontal to vertical pipe delivery machine that is mountable to a drilling rig. The horizontal to vertical machine delivers sections of pipe to a pair of drilling rig mounted elevators. The elevators receive and vertically translate the sections of pipe. A power tong may be used to make connections between the sections of pipe to form a pipe stand, and may also break the connections of the pipe stand. A drill floor mounted pipe racking system receives the connected drill pipe from the elevators. A pipe racking system that may be used in conjunction with the stand building system is capable of controlled, rapid, and precise movement of multiple connected sections of pipe.

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, and a gripper affixed to the end of the arm opposite the boom. A pair of arm-tensioning mechanisms is connected to the arm and provide for tensioning of the arm. A pair of boom-lateral-adjustment mechanisms is connected to the upper portion of the boom and provide for lateral adjustment of the boom. A pair of rocker-arm-adjustment mechanisms is connected to the link and provide for adjustment of the link.
摘要:
The invention relates to a pipe handling apparatus that delivers and positions tubulars at a wellhead and a device for assisting pivotal movement of a boom relative to a base of the apparatus. A pneumatic spring assembly is pivotally connected between the boom and base. During operation, the pneumatic spring assembly urges the boom from a first position to a second position and resists movement of the boom from the second position to the first position. A pneumatic reservoir may be attached to the pipe handling apparatus. A gas-charging assembly fluidically connects the pneumatic spring assembly and pneumatic reservoir and allows the pneumatic reservoir to vary the pneumatic pressure within the pneumatic spring assembly. Sensors mounted in the pipe handling apparatus may provide feedback to a controller which may automatically adjust the amount of pneumatic pressure within the pneumatic springs for ideal performance of the springs.
