摘要： A power tong set (9), with lead and back-up tongs (9a, b), is mounted on the slip bowl (7) of the traveling jack head (6) of a snubbing unit (2) and rotates with the slip bowl (7). Service lines (or umbelicals) for the tong set are not connected during string (ps) rotation. In an alternate version of the apparatus, a fluid feed through swivel (11) is mounted on the tong set (9), secured to the necessary tong operating and control service fluid line, or lines, such that the tong set (9) can rotate with tong service lines between the tong set (9) and the snubbing unit (2) during rotation. In an alternate form, the tong set (9) is mounted on the jack head (6), independently of the rotary table, and the tong set (9) does not rotate when the rotary table rotates.

摘要： A pipe running tool for use in an oil drilling system and the like comprises a lower drive shaft adapted to engage a drive shaft (28) of a top drive assembly for rotation therewith. The pipe running tool further includes a lower pipe engagement assembly (16) which is driven to rotate by the lower drive shaft, and is designed to releasably engage a pipe segment (11) in such a manner to substantially prevent relative rotation between the two. Thus, when the lower pipe engagement assembly is actuated to securely hold a pipe segment, the top drive assembly may be actuated to rotate the top drive output shaft (28), which causes the lower drive shaft and lower pipe engagement assembly (16) to rotate, which in turn rotates the pipe segment (11).
摘要翻译：用于石油钻井系统等的管道运行工具包括适于与顶部驱动组件的驱动轴接合以便与其一起旋转的下部驱动轴。管道运行工具还包括下管接合组件，该下管接合组件被下驱动轴驱动旋转，并且被设计成以这样的方式可释放地接合管段，从而基本上防止两者之间的相对旋转。因此，当下管接合组件被致动以牢固地保持管段时，可以致动顶部驱动组件以旋转顶部驱动输出轴，这使得下驱动轴和下管接合组件转动管段。

摘要： An improved slip-type elevator locking mechanism has a lock rod which has one end connected to the slipsetting yoke and a free end extending generally parallel with the direction of movement of the slips in the elevator bowl. A cam arm mounted on the elevator at a central pivot point has a cam throat on one end which is adapted to receive the lock rod free end and an opposite end and is pivotable about the central pivot point between upper and lower lock rod engaging positions and a neutral, unlocked position. A fluid cylinder is pivotally mounted by a base end to the elevator and is pivotally attached at its output shaft to the cam arm opposite end for urging the cam arm to the neutral position. The fluid cylinder output shaft is spring-biased outwardly away from the base end in the absence of fluid pressure on the cylinder. A yoke rod has one end connected to the slip-setting yoke and a free end extending in a direction generally parallel to the lock rod in a plane which intersects the plane of the cam arm opposite end. Upper and lower coil springs on the yoke rod urge the cam arm toward a select one of the upper and lower lock rod engaging positions when fluid pressure is lost.

摘要： An elevator for use in handling a tubular includes a first body part coupled to a second body part; and at least two slips coupled to each of the first and second body parts, wherein one or more of the slips includes an engagement member for coupling with a mating member of the first body part or the second body part, wherein at least 25% of the engagement member is coupled with the mating member when the slip is in an open position. In another embodiment, a swivel includes an upper housing rotatably coupled to a lower housing; and a rotary union having a rotating body attached to the lower housing and a non-rotating body attached to the upper housing, wherein the swivel is configured to transfer load from the lower housing to the upper housing.
