Estimating the term…
A sucker rod tong assembly for fastening together sucker rods to a rod coupling, where the assembly can include a two-stage mechanical drive mechanism. The first stage can connect an upper sucker rod to a lower sucker rod via a rod coupling. The first stage can be limited in mechanical ability to tighten the connection to a pre-set shoulder torque value. The second stage can then be hydraulically and mechanically sequenced, using a linear gear drive mechanism, to rotate a main tong pinion gear that can further rotate the sucker rod connection through a fixed circumferential displacement to a mechanical stop.
A method for tightening two sucker rods to a sucker rod connector after reaching the point of hand tightness, the method comprising the step of actuating a linear gear drive to move to a predetermined position, wherein the linear drive gear is in operational connection with sucker rod tongs, the movement of the linear drive gear actuating a circumferential rotational movement of the sucker rod tongs to a pre-determined position.
Use of a linear gear drive in a sucker rod tong assembly used in oil wells, wherein the linear gear drive is operatively connected to a sucker rod tong configured to tighten two sucker rods to a sucker rod connector from a hand-tight first position to a predetermined second position by rotating one of the two sucker rods.
A sucker rod tong assembly comprising a linear drive mechanism adapted to tighten a sucker rod to a sucker rod connector from a first hand-tight position to a second predetermined position, wherein the linear drive mechanism is operatively connected to a sucker rod tong such that positive movement of the linear drive mechanism actuates rotational movement of the sucker rod tong to tighten the sucker rod to the sucker rod connector.
A device for use in the tightening of two sucker rods to a sucker rod coupling, the device comprising a first stage tightening mechanism and a second stage tightening mechanism, wherein the second stage tightening mechanism comprises a linear drive mechanism operatively connected to a sucker rod tong, the linear drive mechanism configured to move the sucker rod tong from a first position circumferential position to a second predetermined circumferential position.
