Definitions

  • the invention relates to a drill string guiding device for assistance in the joining of drill string components, where a plurality of joined drill string components form a continuous drill string being connected to a cutter head at its outer end.
  • drill string components in the form of rods or pipes are joined so as to form a continuous drill string.
  • the drilling is performed stepwise, wherein the drill string is advanced by length of one drill string component at the time, followed by a stop during which another drill string component is fastened to the drill string component of the drill string that is closest to the drive arrangement.
  • the drilling may be performed downwards, sideways, upwards or any angle there between.

  • the holding wrench is arranged to hold drill string components during assembling and disassembling of a drill string.
  • the holding wrench is arranged to fix the drill string from rotational movement during such assembling and disassembling of the drill string.
  • a problem that arises especially when the drilling is not performed straight downwards or upwards is that bending forces act on the drill string. These bending forces are particularly troublesome to handle in the joints between the drill string components, especially if the components are hollow, e.g. tubular.
  • drill string components may be utilised in drilling applications where the crushed rock residues are transported within the drill string comprised of a plurality of interconnected drill string components.
  • the cutting head which is arranged at the outer end of the drill string, has a wider diameter than the drill string itself.
  • the drill string may be hanging within the bore hole between the two fixed points constituted by the cutting head at one end, and the drill rig at the opposite end.
  • pipe sections have a relatively short service life and particularly that the connective portions thereof, which typically include threads, are prematurely worn out, such that one or more drill sections need to be machined or even replaced after just a few drilling operations.
  • the invention relates to a drill string guiding device for holding elongate drill string components during assembling or disassembling of a drill string in a drilling operation, each drill string component having a connective portion at each end for interconnection with an adjacent drill string component, the drill string guiding device comprising a frame with an opening through which the drill string is arranged to protrude during operation, the drill string extending in an axial direction; a holding device arranged to hold a drill string component of the drill string as an adjacent drill string component is being connected thereto or removed therefrom; and a positioning device arranged on the frame for positioning the holding device between an inactive position in which it allows free passage of the drill string through the opening of the frame, and an active gripping positon in which it is arranged to hold the drill string component as an adjacent drill string component is to be connected thereto or removed therefrom.
  • the holding device comprises a guiding support comprising upper, lower and side portions arranged to at least partially enclose and fix a portion of said first drill string component when in the active position and at least one guide surface, extending in the axial direction of the drill string from the guiding support to support said first drill string component and thereby align the drill string along its axial direction when in the active position.
  • the drill string component to or from which another drill string component is to be connected or removed, is rectified.
  • the connective portions of the respective drill string components to be connected or disconnected are aligned such that harmful effects are avoided.
  • the connective portions are formed of threads, but they may also be formed of interacting cam surfaces or a bayonet coupling.
  • the holding device comprises two sections that are arranged to be positioned from opposite sides of the drill string component, each section comprising separate parts of the guiding support and of the at least one guide surface.
  • substantially horizontal tracks are arranged on the frame, and wherein the two sections of the holding device comprise tracks arranged to be slided sideways along said tracks between the active position and the inactive position.
  • the holding device comprises two sections that are arranged to be positioned from opposite sides of the drill string component, each section comprising separate upper and lower guide surfaces.

  • the holding device comprise a wrench portion with non-circular surfaces for interaction with a corresponding non-circular surface of said first drill string component.
  • both separate sections of the holding device comprise a separate wrench portion with non-circular surfaces for interaction with a corresponding non-circular surface of said first drill string component.
  • the wrench portion may constitute the guiding support, comprising upper, lower and side portions arranged to partially enclose and fix a section of said first drill string component, when the holding device is in the active position.
  • the invention relates to a rock drilling machine for drilling a hole in a rock by means of a cutting head arranged on the drilling machine via drill string components, wherein the drilling machine comprises a drill string guiding device as described above.
  • the invention relates to a method of joining drill string components to drill string by means of a drill string guiding device as described above, the method comprising the steps of positioning the holding device in the active gripping position, and by means of a guiding support of the holding device, axially aligning said first drill string component of the drill string, the guiding support having an a guiding support comprising upper, lower and side portions arranged to partially enclose a section of said first drill string component and at least one guide surface, extending in the axial direction of the drill string to support said first drill string component, and connecting or disconnecting a drill string component to or from said first drill string component of the drill string, while said first drill string component is held by said guiding support of the holding device.
  • the method may further comprise the step of, by means of a wrench portion of the holding device, holding said first drill string component of the drill string, the wrench portion comprising a non-circular surface for interaction with a mating non-circular surface of the drill string component.

  • the invention is however useful in any type of drilling where the drill string will be exposed to forces acting at least partially orthogonally with respect to the drill string, including but not limited to slotboring, raise boring, and the boring of box holes, easer holes, air holes or the like where a relatively wide cutting head, with respect to the diameter of the drill string, is used.
  • Fig. 1 shows a rock drilling machine 1 in excavating operation at an underground location.
  • the rock drilling machine comprises a derrick 5, which is secured in a rock drilling position at the underground location.
  • a drill string 4 comprised of several hollow drill string components 3, 3', 3" extends from the derrick 5.
  • a cutting head 16 and pilot bit 17 are arranged at the outer end of the drill string 4, extending into the rock which is being excavated.
  • the cutting head is arranged to crush the rock into muck, which is transported through the drill string 4 to an unloading station for subsequent extraction of metals or the like.
  • the rock drilling machine may also be used to simply provide a through hole, e.g. to produce a tunnel or to connect different mining galleries for pressure equalizing purposes. In such cases extraction of metals or the like from the muck is optional.
  • Fig. 2 is a perspective view of the rock drilling machine 1 showing a compartment 22 on which several drill string components 3 may be stored.
  • a handling device (not shown) is arranged to lift one drill string component at a time between the compartment 22 and an operating position 23 where it is arranged to form part of the drill string 4 with the cutting head 16 extending out through an opening 7 of a frame 6 arranged on the derrick 5.
  • the frame 6 forms part of a drill string guiding device 2, which constitutes a first aspect of the invention, as further described below.
  • the frame 6 may be any part that is firmly attached to the derrick 5.
  • An object of the frame is to fix a holding device, which is further described below, with respect to the rotation unit 20, and hence with respect to the derrick 5.
  • the rotation device 20 is arranged to provide the rotational movement so as to thread or unthread a drill string component to or from the drill string 4. Further, the rotation device is movably arranged so as to be translated in the axial direction A 1 of the drill string 4 for a little bit more than a full length of a drill string component 3.
  • Fig. 3 is a side view of a drill string 4 extending from a rotation unit 20 and part of a drill string guiding device 2 in accordance with the invention.
  • the drill string guiding device 2 is arranged to hold one drill string component 3' as another drill string component 3 is being connected thereto, or during dismounting of the drill string, as another drill string component 3 is being removed therefrom.
  • the drill string component is provided with a connective portion 31,32 at each end for interconnection to an adjacent drill string component.
  • these connective portions 31,32 are comprised of interconnectable threads, but they may also be formed of interacting cam surfaces or a bayonet coupling.
  • a male thread 31 is provided at a first end and a female thread 32 is provided at the opposite end.
  • the drill string component 3 comprises a non-circular surface 33, typically a polygonal surface, and a cylindrical portion 34.
  • cylindrical portion denotes an elongate portion that has substantially the same cross section along its whole axial extension. It may have, but does not have to be, a circular cross section throughout its whole axial extension. The cylindrical portion does however have substantially the same width for its whole extension.
  • the drill string guiding device 2 in the sown embodiment comprises a holding device 8 adapted to interact with said non-circular surface 33 and cylindrical portion 34 so as to hold the innermost drill string component 3' as another drill string component 3 is being connected, e.g. threaded, thereto or, during dismounting, to hold the second innermost drill string component 3' as the innermost drill string component 3 is being disconnected, e.g. unthreaded, therefrom.
  • Fig. 4 is a perspective view of the drill string 4 extending from the rotation unit 20.
  • the holding device 8 of the inventive drill string guiding device 2 is shown in a part open mode for illustrative purposes. Specifically, in the shown embodiment, the holding device 8 comprises two sections, whereof one (the left in the figure) is positioned in an active gripping positon holding the drill string component 3', and the other section (the right section in the figure) is in an open mode with no contact.
  • the holding device 8 comprises a wrench portion 9 with a non-circular surface 10 (see figure 8 ) for interaction with a corresponding non-circular surface 33 of the drill string component 3' so as to fix the drill string component 3' from rotation, a guiding support 11 for partly enclosing and fixing the drill string component 3', and at least one guide surface 12a,12b (see figure 8 ) for aligning the same.
  • the guide surface 12a,12b is arranged at a distance in the axial direction A 1 of the drill string from the guiding support 11 and the non-circular surface of the wrench portion 9.
  • the guiding support 11 comprises upper, lower and side portions arranged to partially enclose and fix a portion of the drill string component 3' when in the active position.
  • the guiding support 11 is comprised of two semi-circular supports which together enclose the whole circumferential of a portion of the drill string component 3'. It is however sufficient that the guide support 11 comprise three support surfaces preferably arranged 120° apart.
  • the aim of the guide support is to fix a portion of the drill string component 3' from moving upwards, downwards or sideways. Exactly how this fixing may effectively be achieved is readily understandable to a person skilled in the art. In a way, the guiding support 11 creates a pivot point around which the drill string component 3' may pivot to a certain degree.
  • the guide surface 12a,12b is hence arranged to limit the possibility to pivot and to align the drill string component 3' in the axial direction A 1 of the drill string 4.
  • the wrench portion 9 may alone constitute the guiding support 11, such that the wrench portion 9 comprises contact surfaces 10 that fix a portion of the drill string component 3' from moving upwards, downwards or sideways.
  • the holding device 8 comprises both a guiding support 11 and a wrench portion 9 that both contribute to fixing the drill string component 3'.
  • the wrench portion 9 may however just as well be arranged separate from the holding device 8, being positionable between an active, gripping position and a positon allowing unhindered passage of the drill string 4 by means of a separate positioning device (not shown).
  • the extension of the contact surface between joint extension of the guide surface 12a,12b and the guide support 11 of the holding device 8 and the cylindrical portion 34 of the drill string component equals a length L 2 , corresponding to a part of the full length L 1 of a drill string component.
  • said length L 2 corresponds to at least a fifth of said full length L 1 , or more preferably at least a quarter of said full length L 1 , or even a third of said full length L 1 .
  • the axial extension of the wrench portion 9 of the holding device 8 is to be counted as included in said length L 2 if it is tight enough to contribute to the alignment of the drill string 4. This is preferably the case. Namely. in view of that space for the rock drilling machine is very limited both at the operation location and during transport in connecting between different operation locations the axial length L 2 of the holding device 8 may not be too long.
  • each section of the holding device 8 is arranged on a sliding element 18 provided with rails 19 for sliding interaction at its upper and lower end.
  • the holding device may of course be directly provided with means for sliding interaction with the frame 6.
  • an intermediate arrangement such as the two sliding elements 18 is useful.
  • the rotation device 20 is arranged to provide the rotation of the drill string component 3 that is being connected or disconnected to or from the drill string 4.
  • the drilling machine After a successful adding of a drill string component 3 the drilling machine is operated such that the cutting head 16 is advanced a full length L 1 of one drill string component, whereby the operation of adding another drill string component is repeated until the excavation operation has been concluded, whereupon the operation is reversed and the drill string components are removed one by one.
  • Figs. 5 and 6 are perspective views of an embodiment of a drill string guiding device 2 in accordance with the invention, in an open and closed mode, respectively.
  • the sliding element 18 carrying the holding device 8 is arranged on a frame 6 with an opening 7 through which the drill string 4 is arranged to protrude in the axial direction A 1 during operation.
  • the frame 6 carries tracks 15 for a track-rail sliding interaction with the sliding elements 18.
  • the sliding elements 18 could be provided with tracks and the frame 6 with interacting rails. Either way, the tracks are preferably arranged substantially horizontally.
  • a positioning device 13 is arranged on the frame 6 for positioning the holding device 8, and hence the sliding element 18, between an inactive position in which it allows free passage of the drill string 4 through the opening 7 of the frame 6, and an active gripping positon in which it is arranged to hold a drill string component of the drill string 4 as an adjacent drill string component is to be connected thereto or removed therefrom.
  • the wrench portion 9 and the guiding support 11 of the holding device 8 are interconnected to each other. Further, an upper and a lower guide surface 12a,12b are arranged and extend away from the guiding support 11 and the non-circular surface 10 of the wrench portion 9.
  • a positioning device 13 is arranged to position both the wrench portion 9 and the guiding support 11 between the inactive position and the active gripping position.
  • the positioning device 13 comprises hydraulic cylinders 14 arranged to move the two sections of the holding device 8 and the sliding elements 18 on which they are arranged between the inactive position ( fig. 5 ) and the active gripping position ( fig. 6 ).
  • the length L 2 as defined above only concern the lower guide surface 12b of the guiding support 11.
  • an outer portion of the lower guide surface 12b may be arranged at an outward distance in the axial direction A 1 of the drill string 4 with respect to an inner portion of the opposed upper guide surface 12a for aligning said first drill string component 3' along its axial direction A 1 .
  • the drill string 4 will be hanging between the cutting head at its outer end and the drilling machine at its inner end, such that merely the outer portion of the lower guide surface 12b and the inner portion of the upper guide surface 12a will be in contact with the surface of the drill string component 3' to be held.
  • an outer portion of the lower guide surface 12b is arranged at an outward distance in the axial direction A 1 of the drill string 4 with respect to an inner portion of the opposed upper guide surface 12a.
  • an inner portion of the lower guide surface 12b is preferably arranged at an inward distance in the axial direction A 1 of the drill string 4 with respect to the outer portion of the lower guide surface 12b.
  • the lower guide surface 12b comprises an inner and an outer portion that are spaced apart from each other in the axial direction of the drill string 4.
  • the holding device 8 is primarily adapted to align the torques acting upwards or downwards on the drill string. This is because these are generally the most important forces acting on the drill string 4.
  • the shape of both the upper and lower guide surfaces 12 and 12b, respectively is also adapted to align the drill string 4 sideways, the guide surfaces 12 and 12b extending circularly so as to support the drill string component 3' that is being held.
  • the upper and lower guide surfaces 12 and 12b may be part cylindrical.
  • the upper and lower guide surfaces 12 and 12b are half cylindrical, and interconnected to each other so as to form a cylinder arranged to enclose the drill string component 3' to be held and support it in all directions.

  • each non-circular surface 10 is in fact divided into two flat surfaces 10a and 10b, respectively, which are arranged at an angle of about 6° with respect to each other.
  • these surfaces 10a are arranged to support a drill string component 3' when another drill string component 3 is being threaded thereto, and the other four surfaces 10b are arranged to support a drill string component 3' when another drill string component 3 is being unthreaded therefrom. After closing of the holding device around a drill string component the drill string component is allowed to rotate about 3° in the appropriate direction before abutting contact is made with the non-circular surfaces 10a or 10b.
  • the upper and lower non-circular surfaces 10a and 10b which are opposing each other, are arranged on the same section of the holding device 8 (the left in the figures). This is advantageous as it eliminates the risk of having these surfaces displaced with respect to each other.
  • the wrench portion comprising the upper and the lower non-circular surfaces also comprises chamfered portions 21 arranged to facilitate assembly/closing of the holding device 8. Further, the wrench portion comprises an outer chamfered portion 25 to facilitate closing of the holding device 8 and to help align the sections of the holding device to each other.
