Abstract
A tool for holding a well column pipe, the tool incorporating a plate having a lateral end, an oppositely lateral end, a longitudinal end, and an oppositely longitudinal end; a seam extending oppositely laterally from the plate's lateral end, the seam dividing the plate into longitudinal and oppositely longitudinal segments; a hinge connected operatively to the plate at a lateral end of the seam; a releasable latch connected operatively to the plate at an oppositely lateral end of the seam; a jaw connected operatively to a segment selected from the group consisting of the plate's longitudinal segment and the plate's oppositely longitudinal segment, the jaw being adapted for frictional engagement with the well column pipe; and a jack screw actuator for driving the well column pipe against the jaw.
Claims18
A tool for holding a well column pipe at the upper end of a casing pipe, said tool comprising:
- (a) a plate having a lateral end, an oppositely lateral end, a longitudinal end, and an oppositely longitudinal end, the plate being laterally oblongated;
- (b) a seam having longitudinal and oppositely longitudinal faces, the seam extending oppositely laterally from the plate's lateral end, said seam dividing the plate into longitudinal and oppositely longitudinal segments, each of said longitudinal and oppositely longitudinal segments being laterally oblongated for, upon placements of said segments over the upper end of the casing pipe, bridging across said upper end;
- (c) longitudinal and oppositely longitudinal concavities respectively formed by the seam's longitudinal and oppositely longitudinal faces;
- (d) a hinge connected operatively to the plate, the hinge being positioned at a lateral end of the seam;
- (e) a releasable latch connected operatively to the plate, the releasable latch being positioned at an oppositely lateral end of the seam;
- (f) at least a first jaw fixedly attached to or formed wholly with a segment selected from the group consisting of the plate's longitudinal segment and the plate's oppositely longitudinal segment, said jaw being adapted for frictional engagement with the well column pipe;
- and
- (g) means for driving the well column pipe against the at least first jaw, wherein one of the faces among the seam's longitudinal and oppositely longitudinal faces forms a groove component of a tongue and groove combination, wherein the other face among the seam's longitudinal and oppositely longitudinal faces forms a tongue component of said tongue and groove combination, and wherein said tongue and groove combination is positioned between the hinge and the releasable latch, wherein the means for driving the well column pipe against the at least first jaw comprises a second hinge comprising an axle connected operatively to the at least first jaw, and wherein the at least first jaw comprises a clamping block, wherein said clamping block comprises a pair of arms extending oppositely from the axle, wherein each arm among the pair of arms has a distal end, wherein each arm's distal end presents a plurality of teeth.
A tool for holding a well column pipe at the upper end of a casing pipe, said tool comprising:
- (a) a plate having an upper surface, a lateral end, an oppositely lateral end, a longitudinal end, and an oppositely longitudinal end;
- (b) a seam dividing the plate into longitudinal and oppositely longitudinal segments;
- (c) longitudinal and oppositely longitudinal concavities respectively formed within the longitudinal and oppositely longitudinal segments;
- (d) a hinge connected operatively to the plate, the hinge being positioned at a lateral end of the seam;
- (e) a releasable latch connected operatively to the plate, said latch being positioned at an oppositely lateral end of the seam;
- (f) a clamping block and axle combination attached to the plate's longitudinal segment, wherein said combination's clamping block comprises a pair of arms extending oppositely from the axle, wherein each arm among the pair of arms has a distal end, wherein each arm's distal end presents a plurality of teeth, wherein, upon a further extension of one of the arms toward the longitudinal concavity, the plate's upper surface resists pivoting movements of said one of the arms, and wherein, upon an alternative further extension of the other arm toward the longitudinal concavity, the arm may pivot about the axle;
- and
- (g) means for driving the well column pipe toward the clamping block, said means being connected operatively to the plate.
