a gripping assembly mounted to the actuator assembly, the gripping assembly being movable in response to the actuator assembly between a gripping position in engagement with a pipe and a disengaged position;
a pipe elevator pivotally mounted to lower ends of the link arms below the gripping assembly
a pair of axles extending outward from opposite sides of the support member; and
a bushing at the upper end of each of the link arms that mounts rotatably on one of the axles.
9. An apparatus for handling well pipe, comprising:
a top drive assembly adapted to be mounted to a derrick of a drilling rig;
a tubular connector carried by the top drive assembly for rotation by the top drive assembly;
a support member carried by the tubular connector and spaced below the top drive, the tubular connector supporting a weight of the support member, the tubular connector being rotatable relative to the support member;
a pair of link arms, the arms having upper ends that are pivotally mounted to opposite sides of the support member for rotation relative to the support member about an axis perpendicular to an axis of the tubular connector;
a pair of fluid-powered cylinders, each having a lower end pivotally mounted to one of the arms between the upper and the lower ends;
an actuator assembly mounted to and extending downward from the support member;
the tubular connector being rotatable relative to the actuator assembly;
a gripping assembly connected to the actuator assembly, the gripping assembly having a plurality of grapples and being rotatable in unison with the tubular connector; and
a pipe elevator pivotally mounted to lower ends of the link arms below the gripping assembly.
10. The apparatus according to claim 9 , further comprising:
a pair of cylindrical axles extending outward from opposite sides of the support member; and
a cylindrical bushing at the upper end of each of the link arms that mounts rotatably on one of the axles.
11. The apparatus according to claim 9 , wherein each of the link arms is adjustable in length.
12. The apparatus according to claim 9 , further comprising:
a seal carried below the gripping assembly and above the elevator, the seal adapted to seal an inner diameter of the pipe.
13. The apparatus according to claim 12 , further comprising a nose member having a fluid port and mounted below the seal.
14. The apparatus according to claim 9 , wherein the gripping assembly comprises:
a mandrel connected to the actuator for rotation by the tubular connector and having exterior cam surfaces, the grapples being carried on the mandrel and movable along the cam surfaces between the gripping and disengaged positions in response to the actuator assembly.
15. The apparatus according to claim 9 , wherein the gripping assembly is adapted to slide over and engage an exterior surface of the pipe.
16. The apparatus according to claim 9 , wherein each of the fluid-powered cylinders has an upper end pivotally mounted to the support member.
17. A method for running pipe into a well, comprising:
providing a pipe handling and engaging apparatus comprising: a tubular connector extending upward from and rotatable relative to a support member, a pair of link arms attached to the support member; power cylinders connected to the link arms; a pipe gripping device secured to and extending downward from the support member; and a pipe elevator pivotally mounted to lower ends of the link arms below the pipe gripping device;
suspending the tubular connector below a top drive assembly of a drilling rig such that the support member is spaced below the top drive assembly and a weight of the support member is supported by the tubular connector;
