Definitions
- a string of drill pipe When a string of drill pipe is removed from the well bore it is usually unscrewed in stands or sections of pipe comprising two or three joints of pipe and the stands are placed in racks.
- the stands of pipe When the drill pipe is run into the well bore the stands of pipe are successively screwed to the string of drill pipe and lowered into the well bore.
- the drill pipe is supported from an elevator connected by link to a hook structure.
- the elevator is provided with hinge means to open laterally to release the drill pipe and to shut about the drill pipe in supporting relation.
- the hook structure is swiveled to permit rotation of the drill pipe when the drill pipe is raised from or lowered into the well bore and is provided with means to align the open side of the elevator with the drill pipe in the well bore.
- a suitable hook structure is described in US. Pat. No. 2,732,244, issued Jan. 24, I956.
- the opening and closing of the elevator about the pipe is desirably accomplished by a source of power and by remote actuation.
- a suitable elevator actuated by fluid under pressure is describedin US. Pat. No. 2,695,189, issued Nov. 23, 1954.
- a desirable feature for such equipment is the provision of a swiveling fluid manifold permitting transmission of pressurized fluid from the hook structure to the elevator at every arcuate position of the elevator.
- a suitable swiveling fluid manifold arrangement is described in US. Pat. No. 3,479,062, issued Nov. 18, 1969.
- a swiveling fluid manifold such as described above is operable and resolves the difficulties of line entanglement and twisting
- the structure is subject to damage from impacts with the drill pipe and other objects in the derrick, particularly where the derrick is mounted on afloating platform which moves and tilts about during drilling operations.
- damage is sometimes suffrcient to render the swiveling manifold inoperable, causing a loss of time in drilling operations while repairs are being made.
- Another difficulty in the use of a swiveling manifold which is mounted around the stationary portion of a hook structure is that, when built in operable proportions, the diameter of the manifold to -its axial length causesmore stringent,
- Another object of this invention is to provide a swiveling fluid manifold which is rugged in construction and which is not subject to misalignment or galling when in use.
- An additional object of this invention is to provide a swiveling fluid manifold which rides with the hook of the hook structure, both axially and arcuately, and thus requires no change in length or position of the fluid conductor between the elevator and the hook except as caused by angular movement of the connecting links between the elevator and the hook.
- the invention is embodied in a hook structure having a stationary body and an axially movable and rotatable body with a fluid actuated elevator connected with and movablewith the rotatable portion of the hook structure.
- the improvement comprises: a swiveling fluid conducting manifold having a first element connected in rotatable relation with a second element with the manifold being mounted in recessed and sheltered relation between the stationary body and the rotatable body of the hook structure.
- the manifold means includes means to transmit fluid under pressure from a fluid inlet defined in one element of the manifold to a fluid outlet defined in the other element of the manifold during any arcuate fluid position of either element relative to the other element.
- a fluid conductor is connected from the fluid outlet to the elevator and means positioning the element containing the fluid outlet to an arcuate and axial position corresponding with the position of the rotatable portion of the hook structure and the connected elevator is provided.
- FIG. 1 is an elevational view of a hook structure and elevator arrangement which incorporates the apparatus of this invention.
- FIG. 2 is an enlarged view of a portion, partly in longitudinal section, of the arrangement shown in FIG. 1.
- FIG. 3 is a transverse sectional view taken along the line 3-3 of Fig. l as seen in the direction of the arrows.
- FIG. 4 is a longitudinal section taken along the line 44 of Fig. 3 as seen in the direction of the arrows.
- a hook structure 10 comprising a hook support body 12 and a hookbody l8.
- Elevator links 14 (only one of two links shown) connect an elevator structure 16 to hook body 18 through connection of links 14 with hook ears l and elevator ears l7.
- .l-look structure is supported within a derrick (not shown) by means of a traveling block 19 (partially shown) connected to the hook structure 10 by means of bails ll.

- shank 24 is formed generally cylindrical with opposing fiat surfaces 85 and 85"extending longitudinally over a portion of shank 24 and swivel ring 32 has corresponding flat surfaces within its bore to accommodate the flat surfaces of shank 24 and thereby permit relative longitudinal movement between shank 24 and swivel ring 32 and also to cause corresponding rotation of shank 24 and -swivel ring 32.
- Resilient and longitudinal support for shank 24 is provided by a support spring 27 nested between an upper support sleeve and a lower guide sleeve 28.
- Support sleeve 25 is connected to shank 24 by means of a retainer-ball assembly 26.
- Guide sleeve 28 encompasses. an enlarged cylindrical portion 29 of shank 24 and rests in rigid longitudinalsupporting relation with swivel ring 32.
- Swivel ring 32 is supported in longitudinallyarigidand rotatable relation with housing 22 through a-support bearing assembly 30.
- a stop assembly 31 mounted in housing 22 provides rigid longitudinal support for shank 24 in a direction opposite to that provided by support bearing 30. As provided, shank-24 may be rotated within housing 22 and moved longitudinally upon compression of spring 27.
- -Shank 24 maybe limited inarcuate movement, when desired, in relation to housing 22 by means of a shank positioner lock assembly.34 which may extend into a selected one of .a group of holes disposed about the outer periphery of swivel ring.32. Positioner lock 34 is locked during drilling operations and at other times at the option of the drilling equipment operator.
- shank 24 is connected to a cam ring through a cam positioner nut and collar assembly 42.

- cam roller assembly 36 which is mounted in an end of housing 22 with the axis of the cam roller assembly 36 being disposed normal to the'axis of housing 22.
- spring 27 is placed in initial compression which forces the cam roller 36 against cam face 38.
- the sp'ri'ng'27 is more or less compressed a distance corresponding to the axial dimension variation of cam face 38 as previously described. Accordingly, if the shank 24 has no restraint against rotation, the compressive force of spring 27 will cause the cam roller assembly 36 to drive cam ring 40 to a predetermined position corresponding to the least axial dimension of cam face 38 from the preselected reference point.
- the purpose, construction, and general operation of hook support body 12 is further described in previously referenced US Pat. No. 2,732,244.
- shank 24 is connected to hook body 18 by means of a hook support pin assembly 46 which is fitted through corresponding holes 47 and 47' defined in the shank and hook body.
- a hook support pin assembly 46 which is fitted through corresponding holes 47 and 47' defined in the shank and hook body.

- the manifold structure 20 is of rugged and compact structure and sheltered effectively by the hook support body 12 and body 18 against impacts from objects moving in the vicinity of hook structure 10.
- swiveling manifold 20 is seen to incorporate a circular inner sealing ring 48 which has disposed therein support plates 82 and 82 forming chords across the interior of seal ring 48 and reinforced by radially extending webs 84 and 84 respectively.
- Plates 82 and 82 and webs 84 and 84' are. connected to inner seal ring 48 as by welding, for example.
- Plates 82 and 82 are rigidly connected to the flat faces 85 and 85' of shank 24 by cap screw assemblies 86 as best shown in Figs. 3 and 4.

- outer sealing ring 50 has defined therein a radially disposed inlet fluid passage 70 which is in communication with cavity 54.
- Inner sealing ring 48 has longitudinally then radially defined therein an outlet fluid passage 64. With the structure as described, fluid passages 70 and 64 remain in continuous fluid communication through cavity 54 through any relative arcuate position of inner seal ring 48 and outer seal ring 50.
- a fluid inlet conduit 74 is connected into fluid communication with fluid passage 70 through an inlet fitting 72 and a fluid outlet conduit 68 is connected in fluid communication with fluid passage 64 through a fluid outlet fitting 66.
