Abstract

A lifting elevator includes a first elevator segment having a first plurality of slips, a second elevator segment having a second plurality of slips, and a hinge. The first elevator segment and the second elevator segment each have a swept angle of about 180°, and each of the first plurality of slips and the second plurality of slips includes a die configured to grip an external surface of a pipe.

Claims (46)

1. A lifting elevator, comprising:

a first elevator segment having a first plurality of slips;

a second elevator segment having a second plurality of slips;

a third elevator segment having a third plurality of slips;

a first hinge about which the first elevator segment and the second elevator segment are rotatable with respect to each other;

a second hinge about which the first elevator segment and the third elevator segment are rotatable with respect to each other;

a first lifting lug directly coupled to the first elevator segment;

a second lifting lug directly coupled to the first elevator segment,

wherein the first lifting lug and the second lifting lug are configured to carry a load of a conductor string that includes a joint of pipe,

wherein each of the first plurality of slips and the second plurality of slips and the third plurality of slips comprises a die configured to grip an external surface of the joint of pipe; and

a segmented timing ring coupled to the first plurality of slips and the second plurality of slips and the third plurality of slips, the segmented timing ring having a first body segment, a second body segment, and a third body segment adjoined together, wherein an interlocking structure between the first body segment, the second body segment, and the third body segment allows the first body segment, the second body segment, and the third body segment to move vertically together in unison, the interlocking structure comprising a recess in one of the first body segment, the second body segment, and the third body segment to receive a protrusion of a respective one of the first body segment, the second body segment, and the third body segment, wherein the segmented timing ring is above the first, second, and third plurality of slips,

wherein the segmented timing ring is actuated by one of a pneumatically, hydraulically, and electrically powered actuator to raise or lower the each of the first plurality of slips and the second plurality of slips and the third plurality of slips.

2. The lifting elevator of claim 1 ,

wherein the lifting elevator is configured to receive the joint of pipe between the first elevator segment and the second elevator segment and the third elevator segment when in an open position, and

wherein the lifting elevator is configured to grip and lift the joint of pipe from a non-vertical position or vertical position and lowered into a well when the first plurality of slips and the second plurality of slips and the third plurality of slips are engaged with the joint of pipe in a closed position.

3. The lifting elevator of claim 1 , wherein the first elevator segment comprises a first tapered surface that the first plurality of slips are movably disposed along, and wherein the second elevator segment comprises a second tapered surface that the second plurality of slips are movably disposed along, and wherein the third elevator segment comprises a third tapered surface that the third plurality of slips are movably disposed along.

4. The lifting elevator of claim 1 , further comprising:

a backstop coupled to the first elevator segment.

5. The lifting elevator of claim 1 , wherein the first lifting lug is positioned on the first elevator segment nearby the first hinge and wherein the second lifting lug is positioned on the first elevator segment nearby the second hinge.

6. The lifting elevator of claim 1 , further comprising:

a first powered actuator coupled to the first elevator segment and the second elevator segment; and

a second powered actuator coupled to the first elevator segment and the third elevator segment,

wherein the first powered actuator and the second powered actuator are used to move the second elevator segment and the third elevator segment, respectively, between an open position and a closed position.

7. The lifting elevator of claim 1 , further comprising:

a latch coupled to the second elevator segment, the latch used to couple the second elevator segment to the third elevator segment and to lock the first elevator segment, the second elevator segment, and the third elevator segment in a closed position.

8. A method comprising:

opening a second elevator segment and a third elevator segment of a lifting elevator about a hinge connecting the second elevator segment to a first elevator segment and a hinge connecting the third elevator segment to the first elevator segment;

aligning the lifting elevator with a joint of pipe;

receiving the joint of pipe within the opened lifting elevator;

closing the second elevator segment and third elevator segment of the lifting elevator around the joint of pipe;

gripping the joint of pipe with a plurality of slips of the lifting elevator,

wherein gripping the joint of pipe with the plurality of slips comprises moving the plurality of slips in a downward direction in a tapered bowl via a connection between the plurality of slips and a segmented timing ring, wherein the segmented timing ring is actuated by one of a pneumatically, hydraulically, and electrically powered actuator, and wherein an interlocking structure between a first body segment of the segmented timing ring, a second body segment of the segmented timing ring, and a third body segment of the segmented timing ring allows the first body segment, the second body segment, and the third body segment to move vertically together in unison, the interlocking structure comprising a recess in one of the first body segment, the second body segment, and the third body segment to receive a protrusion of a respective one of the first body segment, the second body segment, and the third body segment, wherein the segmented timing ring is above the plurality of slips;

lifting the gripped joint of pipe using the lifting elevator,

wherein the lifting elevator includes a first lifting lug coupled to the first elevator segment and a second lifting lug coupled to the first elevator segment, and the first lifting lug and second lifting lug are configured to carry a load of the joint of pipe;

positioning the joint of pipe atop a conductor string;

attaching the joint of pipe to the conductor string; and

supporting the joint of pipe and the conductor string with the lifting elevator.

9. The method of claim 8 , wherein receiving the joint of pipe comprises: abutting the joint of pipe against a backstop coupled to the first elevator segment.

10. The method of claim 8 , wherein the first lifting lug is positioned on the first elevator segment nearby the first hinge and wherein the second lifting lug is positioned on the first elevator segment nearby the second hinge.

11. The method of claim 8 , further comprises:

actuating a first powered actuator and a second powered actuator to move the second elevator segment and the third elevator segment, respectively, from an open position to a closed position.

12. The method of claim 8 , wherein:

latching the second elevator segment to the third elevator segment of the lifting elevator closed around the joint of pipe comprises using a latch.

13. The method of claim 12 , wherein:

the latch is pivotably connected to one of the second elevator segment and the third elevator segment.

14. The method of claim 8 , wherein each of the plurality of slips of the lifting elevator comprise a die configured to grip an external surface of the joint of pipe.
