Abstract
A tubular handling apparatus has a main rotating structural member pivotally movable between a first position and a second position, an arm interconnected to the main rotating structural member, and a gripper mechanism affixed to an end of the arm opposite the main rotating structural member. The gripper mechanism has a stab frame, a first gripper translatably attached to a side of the stab frame, and a second gripper translatably attached to the side of the stab frame below the first gripper. A connection bar is connected to the first and second grippers so as to translate the grippers for a substantially identical distance. A translating mechanism translates the grippers along the side of the stab frame.
Claims21
A tubular handling apparatus comprising:
- a structural member movable between a first position and a second position;
- an opening in the structural member;
- an arm interconnected to the structural member so as to be movable in relation to the structural member;
- a frame having a first side affixed to the arm, and having an opposite second side;
- a first and second gripper connected to the second side of the frame so as to extend outwardly therefrom, the first and second grippers being suitable for gripping a surface of a tubular;
- a means for translating the first and second grippers along the second side of the frame;
- and,
- the frame being movable through the opening in the structural member as the structural member moves between the first and second positions.
A tubular handling apparatus comprising:
- a structural member rotatable between a first position and a second position;
- an opening in the structural member;
- an arm interconnected to the structural member, the arm being movable between a home position and an extended position as the structural member rotates between the first and second positions;
- a frame having a first side connected at an end of the arm opposite the structural member;
- a first and second gripper translatably mounted along a second side of the frame opposite the first side, the first and second grippers being suitable for gripping a surface of a tubular;
- and,
- at least one of the grippers passing through the opening in the structural member as the structural member moves between the first and second positions.

- a first and second gripper translatably mounted along a second side of the frame opposite the first side, the first and second grippers being suitable for gripping a surface of a tubular;
- and,
- the second side of the frame being movable from a substantially horizontal position to a substantially vertical position as the structural member rotates from the first position to the second position.
