Abstract
A method and system for coupling a drive unit to a tool adapter includes joining a first plate to a second plate; stabbing a stabbing member of the first plate into a hollow of the second plate; and rotating a bar of the second plate from an open position to a closed position to secure the stabbing member in the hollow. An embodiment includes positioning the tool adapter below the drive unit; stabbing a coupling head into a coupling recess; moving a fixation ring vertically; and securing bolts of the drive unit in notches of the coupling head.
Claims19
A coupling system of a top drive system comprising:
- a first plate having a stabbing member that is perpendicular to the first plate, wherein the first plate includes a central bore:
- a drive stem at least partially disposed in the central bore, wherein the drive stem is rotatable relative to the first plate;
- and a second plate having:
- a hollow complementary to the stabbing member;
- a bar bore in the second plate;
- and
- a bar that is rotatable within the bar bore between an open position and a closed position;
- wherein the stabbing member is secured in the hollow when the first plate is joined to the second plate and the bar is in the closed position.
A coupling system of a top drive system comprising:
- a first plate having a stabbing member that is perpendicular to the first plate, wherein the stabbing member includes a notch;
- and a second plate having:
- a hollow complementary to the stabbing member;
- a bar bore in the second plate;
- and a bar having a coupling recess, wherein the bar is rotatable within the bar bore between an open position and a closed position, wherein at least a first majority of the coupling recess is disposed in the hollow when in the open position, and wherein at least a second majority of the coupling recess is disposed in the bar bore in the closed position;
- wherein the stabbing member is secured in the hollow when the first plate is joined to the second plate and the bar is in the closed position.
