Definitions
- the present invention relates to a sleeve for orientating a tool and in particular, but not exclusively, for orientating a running tool of a drilling system into a predetermined rotational position.
- a bit locking sleeve is used to orientate a tool in a predetermined angular position relative to a drive sub connected with a lower end of a core barrel .
- the bit locking sleeve described in WO 94/29567 is in the form of a cylindrical tube with a pair of opposing peaks extending from one end.
- the tool is used for carrying bit segments to and from the drive sub and is provided with latch dogs which extend radially from the body of the tool .
- latch dogs When the tool is lowered through the core barrel, the latch dogs contact the side faces of the peaks causing the tool to rotate about its longitudinal axis relative to the drive sub. The purpose for this is to correctly align the tool with seats and splines formed in the drive sub so that the bit segments carried by the tool can be properly located in the drive sub.
- the present- 1' invention was developed with a view to substantially reducing the likelihood of jamming occurring between the locking sleeve and tool of the above-mentioned system.
- the present invention has application in systems other than those used in the drilling industry.
- a sleeve for orientating a tool travelling through said sleeve into one of one or more predetermined rotational positions, said tool provided with at least one abutment surface
- said sleeve comprising: a substantially cylindrical member provided at one end with one or more tapered peaks extending in the axial direction of said cylindrical member, one of said peaks being higher than all other peaks; whereby, in use, when a tool provided with at least one abutment surface travels through said sleeve, one of said abutment surfaces can contact said one peak and slide along one side of said one peak causing said tool to rotate about a longitudinal axis of said cylindrical member to orientate said tool toward said predetermined rotational position and wherein any other abutment surface can contact a respective other peak, if present, on a side distant said one side.
- the number and width of the peaks is dependent on the number of predetermined rotational positions that the tool can take as well as the number of abutment surfaces (eg. latch dogs) on the tool. If there is only one protrusion on the tool for contacting the peaks then, to ensure correct angular alignment of the tool the sleeve can have one peak of a width of just less than 360°, of P N peaks of P w width where P N is the number of allowable predetermined positions and P w is slightly less than 360° divided by p N . For example, if the tool can take one of four (evenly spaced) predetermined positions and the tool has only one latch dog the ' sleeve can be provided with four peaks each of about 90° width.
- the sleeve can be provided with either two peaks each of about 180° width, or three or four peaks each of about 90°. In this example one peak should be higher than the others .
- the sleeve can be provided with one, two, three or four peaks each of a width of about 90° .
- the actual number and width of the peaks is not a critical aspect of the invention and can be varied to suit the application at hand and prevailing working conditions. What is important however is that when there is more than one peak on the sleeve, one of those peaks be higher than all others. It is advantageous but, as indicated above, by necessary, that the number of peaks be the same as the number of latch dogs/abutment surfaces provided on the tool.
- said sleeve further comprises a land formed at a lowest point of each of said one or more peaks, each of said lands being adapted to receive respective ones of said abutment surfaces .
- Preferably said lowest points are at the same level.
- said sleeve is adapted for retention within a tubular member through which said tool can travel .
- said sleeve is further provided with guiding means for guiding said sleeve to move linearly in the direction of said longitudinal axis of said tubular member while preventing rotation of said sleeve relative to said tubular member.
- said guide means comprises one of a rail and channel formed on an outer peripheral surface of said sleeve, and the other of said rail and channel formed on an inner circumferential surface of said tubular member.
- said sleeve further comprises releasable locking means for releasably locking said sleeve in at least one position relative to said tubular member so as to resist movement of said sleeve in an axial direction away from said at least one position.
- said releasable locking means comprises at least one groove formed circumferentially about said outer circumferential surface of said sleeve and a radially resiliently expandable ring-like device adapted for retention in a circumferential groove formed in the inner circumferential surface of said tubular member, said ring ⁇ like device configured to sit proud of said inner circumferential surface when in a relaxed state; whereby, in use, when said sleeve is moved linearly to a position where one of the grooves on the sleeve coincides with the groove on the tubular member, said ring-like device is partially seated in both grooves thereby locking said sleeve in said position.
- the grooves on said sleeve are provided with sloping side surfaces leading from said outer peripheral surface to a base of said groove so that when said tool impacts on said sleeve, said ring-like device can be progressively expanded by said sloping side surfaces so that said ring-like device is moved out of said groove in said sleeve allowing said sleeve to move linearly along said tubular member.
- the grooves in said tubular member have square or stepped sides to prevent the escape of said ring-like device therefrom.
- Figure 1 is a longitudinal section view of the sleeve
- Figure 2 is a longitudinal section view of the sleeve within a ground drill
- Figure 3 is an enlarged side view of an upper end of the sleeve shown in Figures 1 and 2;
- Figure 4 is a longitudinal section view of a tool which can be orientated by said sleeve;
- Figures 5A to 5D are schematic top views of further embodiments of the sleeve.
- one embodiment of the sleeve 10 comprises a cylindrical member or tube 12 provided at one end 14 with a pair of opposing tapered peaks 16 and 18 which extend in the axial direction of the cylindrical tube 12.
- the peaks are adapted to cooperate with abutment surfaces in the form of latch dogs 20 and 22 which are evenly spaced about and extend radially from a running tool 24 (refer Figure 4) .
- the sleeve 10 is adapted for location within a tubular member in the form of a drive sub 26 of a ground drill (not shown) .
- the sleeve 10 is allowed to move linearly along the drive sub 26 but is fixed against rotational motion. This is effected by way of guiding means which comprises a plurality of longitudinal channels 70 formed on the outer peripheral surface 30 of the sleeve 10 at its lower end 32; and, a plurality of rails or splines 34 which are formed on the inner circumferential surface 36 of the drive sub 26.
- the splines 34 reside in the channels 70 allowing axial movement of the sleeve 10 but preventing rotational movement.
- the sleeve 10 also includes a releasable locking means for locking the sleeve in one of a plurality of linear positions relative to the drive sub 26.
- the releasable locking means comprises two spaced apart grooves 38 and 40 formed circumferentially about the outer circumferential surface 30.
- the grooves 38 and 40 are intended to cooperate with a radially resiliently expandable ring-like device such as snap ring 42 which is retained within a groove 44 provided in the inner circumferential surface 36 of drive sub 26. Sloping side surfaces 41 run from the outer peripheral surface 30 to the base or bottom 43 of each of the grooves 38 and 40 (refer Figure 3) .
- the snap- ring 42 is configured so that in a relaxed or non-expanded state, a part of the snap ring sits proud of the inner circumferential surface 36.
- the snap ring 42 sits partially in both grooves thereby releasably locking the sleeve 10 in that position.
- the sleeve can be knocked from this position when impacted by the tool 24.
- each of the peaks 16 and 18 have a base of a width substantially equal to the angular spacing between the latch dogs 20 and 22 of the tool 24.
- the peaks 16 and 18 have a base of angular width of approximately (but slightly less than) 180°.
- the number of peaks provided is dependent upon the number of latch dogs on the tool 24, although as shown hereinafter this need not necessarily be the case.
- peaks 16 and 18 be of different height. This is most clearly illustrated in Figure 3 where it is shown that peak 16 is of a height (or length) H units greater than peak 18.
- a land 46 is provided at each side of the base of each peak for seating the latch dogs.
- the tool 10 is able to push the sleeve 10 in a downward direction by virtue of its momentum when the latch dogs 20 and 22 are seated in the lands 46.
- the sleeve 10 is also provided with a plurality of through holes 48 disposed about its length to assist in the flow of drilling fluid through and about the sleeve 10 and drive sub 26. Also, a pair of longitudinally extending and diagonally opposed slots 50 are formed in the sleeve 10 to allow a further set of latch dogs 52 provided in the tool 24 (refer Figure 4) to extend therethrough.
- the sleeve 10 is disposed within the drive sub 26 in a first position in which the groove 40 coincides with groove 44 on a drive sub so that the snap ring 42 releasably latches the sleeve 10 in this position.
- the snap ring 42 prevents the sleeve 10 from moving from this position by the action of gravity.
- the tool 24 rrtay be typically loaded with a set of drill bit segments 54 for connection with a lower end of the drive sub 26.
- the drive sub 26 is provided with a plurality of seats 56 arranged between adjacent splines 58.
- the bit segments 54 are aligned so as to be received by the seats 56. This alignment is achieved by the sleeve 10 and the latch dogs 20 and 22. Particularly, as the tool 24 is lowered into the drive sub, one of the latch dogs 20 or 22 will eventually contact the top or one side of peak 16 or 18.
- the sleeve 10 is moved downwardly to a position where the groove 38 coincides with the groove 44 at which time the snap ring 42 snaps back (ie. contacts in a radial direction) so as to sit partially within both grooves 44 and 38 thereby again releasably locking the sleeve 10 in position.
- the bit segments 54 are locked in the seats 56 by the outer circumferential surface of the sleeve 10.
- Figures 5A-5D show in schematic form a top view of different embodiments of the sleeve 10.
- the sleeve 10 is provided with a single peak 16' and tool 24 with a single latch dog 20.
- the peak 16' has an angular width of substantially 360°.
- Land 46' of the peak 16' is shown as a gap in which the latch dog 20 resides.
- the top or end of peak 16' is shown marked with an X. Indeed, in all of Figures 5A-5D, the top or end of the peaks shown is represented by an X.
- FIG. 5B The embodiment shown in Figure 5B is identical to that shown in Figures 1-3.
- the tops X of the peaks 16 and 18 are at different levels with the highest peak 16 being designate with the character H. It will be appreciated however, in this embodiment that one of peaks 16 or 18 can be removed and the tool 24 will still reside in one of the two angular positions that it must assume if both peaks 16 and 18 were present.
- the tool 24 is provided with three evenly spaced latch dogs 20 and the sleeve 10 provided with three peaks 16, 16' and 16' ' .
- the angular width of each of the three peaks is approximately the same as the angular distance between adjacent latch dogs 20, ie. slightly less than 120° to allow for the provision on the lands 46.
- the sleeve 10 in Figure 5C will correctly orient the tool 24 in one of the three positions it can assume irrespective of whether it has only one or two of the three peaks provided the peaks are of an angular width substantially identical to the angular spacing between the latch dogs 20. Further, to avoid the possibility of jamming as in the prior art, it is again necessary that one of the peaks 16, 16', 16" is higher than the other peaks.
- FIG. 5D A further variation is shown in Figure 5D in which the tool 24 is provided with four evenly spaced latch dogs 20 and the sleeve 20 with four evenly spaced peaks 16, 16' 16'' and 16' ' ' .
- the angular width of each of the peaks in this embodiment is slightly less than 90°, being substantially the same as the angular distance between adjacent latch dogs 20. Again it is important that one of the peaks be higher than the remaining peaks. Further, it will be appreciated that the sleeve 10 in this embodiment will correctly orientate the tool 24 in one of its four possible angular positions irrespective of whether or not the sleeve contains one, two, three or four peaks.
- the latch dogs 20 contact or slide down the distant sides of adjacent peaks. Or, in other words, at least when the number of peaks is the same as (or greater than) the number of latch dogs 20, adjacent latch dogs are spaced by one (or more) peaks. For the sake of symmetry and balance it is preferred in all of the embodiments that the number of peaks equals the number of latch dogs. However, as explained above, this is not an absolute requirement to correctly orientate the tool 24.
- releasable locking means is shown as comprising two grooves 38 and 40 formed on the outer circumferential surface of the sleeve 10, any number of grooves can be used depending on the desired locations at which the sleeve 10 is to be locked.
- the grooves in the sleeve and drive sub can be interchanged so that the snap ring 42 is retained about the sleeve 10 in a square sided groove and the drive sub provided with a number of sloping sided grooves for receiving the snap ring 42.
