Abstract
An apparatus comprising a slip bowl for supporting drill pipe within a well hole and a plurality of carriers associated with the slip bowl. The plurality of carriers are configured to move between an open position and a closed position. At least one spring assist mechanism are each associated with one of the plurality of carriers. The at least one spring assist mechanism biases the associated carrier to maintain the carrier in the open position.
Claims21
An apparatus comprising:
- a slip bowl for supporting drill pipe within a well hole;
- a plurality of carriers associated with the slip bowl, each of the plurality of carriers configured to pivot about a separate pivot point on the slip bowl between an open position and a closed position;
- a hydraulic cylinder connected to each of the plurality of carriers for moving the plurality of carries between the open position and the closed position;
- and
- a plurality of spring assist mechanisms each connected to one of the plurality of carriers, wherein the plurality of spring assist mechanisms biases the connected carrier to maintain the carrier in the open position after the hydraulic cylinder moves the connected carrier to the open position.

- a first tube;
- a second tube configured to telescopically slide into an interior of the first tube;
- at least one magnet connected to the second tube and configured to move with the second tube as the second tube moves telescopically with respect to the first tube;
- and
- a sensor fixedly connected to the first tube, the sensor detecting movement of the at least one magnet and generating signals responsive to the detected movement.
