Description

Device and method for handling drill string components in rock drilling and rock drill rig}

The present invention relates to a handling device for handling an excavation pipe component with respect to an excavation device, the device comprising a transport beam in which the transport and rotation device is displaceable and a second excavation pipe at the excavation pipe position of the excavation device And a lifting winch for lifting the first digging pipe component that is screwed to the component. The present invention also relates to a rock drilling rig equipped with such a handling device and a corresponding method.

Core drilling for exploration purposes is usually carried out with a rock drilling rig, and the drilling pipe component is raised or lowered from the drill hole with the help of a winch, aligned with the working drilling pipe position. The winch wire is fastened to the best digging pipe component with the help of a lifting plug. Since core drilling aims to extract a drilled-out core of the rock being investigated, tubular digging pipe components are used. While raising the excavation pipe, which is often performed for the exchange of drill bits, the tube pipe is raised in units, whereby individual tubes are co-operated with a lower tube holder to excavate. It is released from each other with the help of the rotor device.

Final release of the tube away from the excavation pipe is performed at least partially manually by the operator today, and this handling includes lifting and guiding the tube in the area of a tube magazine and releasing the final threading. .

While descending the digging pipe, the working steps are performed in reverse so that the new digging pipe components in the form of tubes are continuously raised to the position where they are screwed together by the operator aligned with the digging pipe. These work steps are stressful and pose a non-negligible risk of being subjected to ascent and clamping injuries to the operator.

Core drilling is often performed at very large depths, for example excavation lengths between 1000-2000m. Since the drill bit is under wear in operation, the drill bit must be changed relatively frequently, the entire excavation pipe must be released from the excavation pipe component, raised from the drill hole, the worn drill bit removed, and a new It is replaced by a drill bit, so that the excavation pipe is lowered back into the drill hole. As a result, the hole is drilled a longer distance until the drill bit is replaced again. During drilling, a flushing liquid swivel is connected to the top of the excavation pipe to supply the cleaning liquid for transporting the decomposed rock during drilling.

It is an object of the present invention to provide an apparatus of this kind, wherein the problems according to the above are addressed and at least partly solved.

This is achieved by a gripper shuttle with a handling device according to the above, and the gripper shuttle is fastened to the excavation device to extend in the direction from the transport beam while forming an angle with the transport beam. It can be movably arranged along a guide beam that is possibly possible, and the gripper shuttle is arranged to rotate to grip the first end portion of the digging pipe component in the first position in the first outermost position above the guide beam. With a pivotally arranged guiding gripper, intended for lifting from a position outside the excavator, the other end of which is intended to be screwed with a lifting plug or the like to cooperate with the lifting winch And the gripping device shuttle in the second position of the second internal position to the guide beam adjacent to the transport beam. Values are aligned with the guide held device to align with the drilling pipe component held in the deduced.

A guide beam is provided with a pivotally arranged gripper for gripping the first end portion of the first digging pipe component, the other end portion being movably movable arranged in engagement with a lifting plug. A number of advantages are achieved because a possible gripper shuttle is arranged. This greatly facilitates handling during the lifting process with the lifting wire, and both the process of moving the excavation pipe component to the excavation pipe position, as well as the process of lifting and releasing from the excavation pipe component from the excavation pipe position.

According to the background art, there is no corresponding guidance at the most elevated position of the excavation pipe component, and instead, when the excavation pipe component is hung on the lifting wire, it is accurately sent from the excavation pipe position to the delivery position for another transfer. It is up to the operator to ensure the correct positioning of the digging pipe components at each digging pipe location.

Alignment with the gripping shuttle instead allows safe and proper guidance of the free end of the excavation pipe component raised in each position.

The guide beam is a longitudinal guide for the gripper shuttle composed of either the outer part of the guide beam, the lateral edge of the H-beam or I-beam shaped flange of the guide beam, or the mutually facing guide ribs. ) Is preferred. Such alignment is produced easily and cost effectively with sufficient accuracy.

The gripper shuttle can be properly driven by a wire, chain, band or cable with the aid of a stationary and aligned drive motor that allows easy production installation of the drive motor. Alternatively, the gripping device carriage itself supports a driving motor for driving, and the driving device operates against engaging means aligned along the guide beam.

The device preferably comprises a control system arranged to control-drive the movement of the gripper shuttle in relation to the operation of the winch so that controlled transfer of the excavation pipe component is achieved.

In the second position of the gripper shuttle, the guide gripper ensures that the transport beam is accurately positioned so that the excavation pipe component intended to move to the excavation pipe position is gripped in a safe way for further handling during subsequent threading. It is properly aligned to align the gripping digging pipe components in the region of the digging pipe position through cooperation with an aligned alignment guide.

It is preferred that the guide gripping device is operable to rotate between the first rotational position at the first position and the second rotational position at the second position in order to obtain an appropriate guide at each position.

It is appropriate that the guide gripping device is adjustable between open and closed positions through the aid of any one of an electric motor, a hydraulic motor, and an air motor.

It is preferred that the guide beam can be rotated to attach to the rig around the first pivot axis so that it can be easily adjusted at different working positions with different feed beam angles of the rig.

Preferably, the guiding beam in the outer region can be attached to rotate around the support about the first pivot axis. This support can be a support body for handling components, a magazine or other arrangement.

Preferably, a gripper unit is arranged in the rig to engage the first end portion of the rigging pipe component, the gripping rigging component being guided in the region of the rigging pipe location. It is aligned by, and thereby, accurate transfer from the guide gripping device is ensured.

The present invention also relates to a rock drilling device comprising a rotor device which rotates and drives an excavation pipe, and the front and rear movements are supported by a transport beam, the rock drilling device comprising a handling device according to the above.

The present invention also includes a transport beam, wherein the transport and rotation device is displaced above the transport beam, and the first excavation pipe component is raised to be screwed to a second excavation pipe component in the excavation device's excavation pipe position. The method relates to a method for handling an excavation pipe component in an excavation device.

The above method,

-While the gripping device shuttle forms an angle with the transport beam, it is operatively arranged along the transport beam which is fasten to the excavation device so as to extend in the direction from the transport beam,

The gripper shuttle in the first, outermost position on the guide beam, with the guide gripper arranged to be rotated, grips the first end portion of the excavation pipe component intended for lifting from the outside position of the excavator, The other end part is screwed with a lifting plug or the like to cooperate with the lifting winch, and

-In the second, internal position on the guide beam adjacent to the transport beam with the guide gripping device, the gripping device shuttle is characterized by aligning with the excavating pipe component gripped in the region of the excavating pipe position.

The advantages presented above in relation to the handling device and the dependent features of the invention are also applicable to the method of the invention.

For the purpose of ensuring effective and safe alignment between the gripping unit and the excavating pipe component supported by the pivoting arm, the guiding beam is appropriately used, and the gripping unit as well as the delivery of the excavating pipe component sent to the excavating apparatus It is configured and arranged to form a mechanical stop for the pivoting arm in position. Such alignment may include adjusting the reference beam through a mechanical stop on the one hand and, on the other hand, for the gripping unit, the end of the excavation pipe component, which is supported by the pivoting arm, is also almost automatic. It provides what is located.

The present invention provides significant handling advantages because the operator is often rescued from the medium pressure of the driving operation. Better drilling economy can be expected because the components can be handled in the direction of elevated travel speed during handling without the risk of injury to the operator.

It should be noted that the alignment requirements for screwing the excavation pipe components together for core drilling are very stringent. Therefore, the misalignment of more than 1 mm of the components screwed together is not allowed. A larger angular deviation is likely to result in a more serious case of screwing failure and screw damage.

It is preferred that the guide beam is rotatably attachable around the first pivot axis in relation to the area of the first pivot axis of the gripper unit, and in particular it is preferred that the first pivot axis is at least essentially coaxial with the first pivot axis. Similarly, it is preferred that the guide chest is rotatable so as to be rotatable around the second pivot axis in relation to the area of the second pivot axis of the pivot arm, and preferably the second pivot axis is at least essentially coaxial with the second pivot axis. It becomes. This alignment is facilitated one by one, and in particular combined into one, eliminating the need to adjust the cooperating means on the guide beam and / or the gripper unit with it, and for the end of the guide beam (such as a reservoir) or Even in the case of the intended movement of the rig, or after repositioning the rig, the rotating arm faces away from the rig.

1 shows a feed beam 2 of a rock drilling rig for core drilling that can be adjusted from different angles. The drilling device comprises a rotator device 4 supported on a transport beam 2 for moving back and forth. Below the rotor device 4 (in the drawing) a tube holder 5 is arranged as required to temporarily hold the excavation pipe.

Power and driving aggregates for verifying pressure fluid and the like are arranged next to the transport beam 2 on a rock rig (not shown) and a lifting winch (not shown). It will be described below that a magazine 6 is aligned to accommodate the excavation pipe components (indicated by the dotted line 8), and in some respects being disengaged and moved from the rock excavation, respectively.

The storage device 6 can be configured in a variety of ways, but is generally illustrated in FIG. 1 in the form of a horizontal table, wherein the horizontal table has a digging pipe component 8 of the digging pipe component 8. It is possible to incline to be moved by rolling toward a swing arm 7 for accommodation.

In the position during a lifting phase in a slanting position with respect to the transport beam, the digging pipe component is further indicated in FIG. 1 by an 8 "dashed line.

This line, 8 "in FIG. 1, is intended to illustrate an intermediate position during the lifting phase terminated by a digging pipe component in a position coaxial with the working digging pipe position of a rock drilling rig. Lifting is carried out with the help of a lifting plug 25 (see below) screwed on top of the excavation pipe component, which is eventually connected on a lifting wire (not shown) during this process and on the transport beam. On top of it passes through a wire wheel (not shown), and a second part thereof extends essentially parallel to the transport beam with a lifting winch (not shown) aligned with the area of the power and drive assembly 3 do.

Also shown in FIG. 1 is a lifting plug 25 gripped by a gripper unit 11 and screwed to the end portion of the excavation pipe component 8 ′ in the excavation pipe position. .

FIG. 1 also shows that the end portion is drawn from the rotating device 4 such that the digging pipe component 8 ′ is in the acting digging pipe position A. The digging pipe component 8 'has a female thread that engages in correspondence with the male thread of the lifting plug 25.

Screwing with an additional second digging pipe component (8 ") to the first digging pipe component (8 ') for the purpose of lengthening the digging pipe for subsequent descent into the drill hole is basically a method of screwing to the lifting plug and basically Yes, see below.

The gripping unit 11 is shown in the first position in FIG. 1, and the gripping position is defined by the gripping unit 11 and provides a gripping position axis G (see the dotted line in FIG. 1). And is coaxial with the working excavation pipe position (A).

In this figure a guiding beam 19 is shown in more detail and to provide a stop for the pivoting arm 7 in the guiding position pivoted upward of the supported excavation pipe component 8. Aligned. Further, the guide beam 19 provides a stop for the gripping unit 11 in the second position. A plate-shaped support means for supporting the excavation pipe component is shown as 7 '.

The gripping unit 11 shown in more detail in FIG. 2 is in the form of a rotating gripping unit, the first set of gripping elements for coupling with the first digging pipe component 8 '(in FIG. 1) and the rotating means 14 Equipped with a first set of grippers 12, the rotary gripper unit is not only for the drive rollers 20 for engaging the components, such as the excavating pipe component to be rotated, but also for these rotary drive rollers. A drive motor 21 is provided. In addition, the gripping unit 11 is provided with a second set of grippers 13 that cooperate with a rotating gripping unit for engaging components. Each set of grippers 12, 13 includes a pair of gripping components, such as grippers jaws individually adjustable to also function as stoppers of the advanced digging pipe components. The same holds true for a rotating gripping unit comprising a pair of rotating gripping means.

The first set gripping device 12 is adjusted by a hydraulic cylinder, one of which is indicated by reference numeral 15, and the second set of gripping devices is adjusted by the aid of a hydraulic cylinder 17.

The rotating device 14 with a drive roller is supported by a rotatable rotating clamping means, which is shown in one and is moved in engagement with a component which is rotated by a hydraulic cylinder indicated by reference numeral 16.

The part of the gripping unit 11 comprising the rotating means 14 and typically also the second set gripping device 13 can be displaced in a direction parallel to the gripping position axis 3. See both arrows. The purpose of this displaceability is to provide axial movement and rotation of the drive rollers to be compensated for for the thread pitch during rotational drive of the gripping unit and in particular the component being rotated on the part of the rotating means 14.

FIG. 2 also rotates around a first swing axis Al between the position shown in FIGS. 1 and 2 described below (first position) and the outwardly rotated position (second position). It shows a swing unit 18 which supports the gripping unit 11 for doing so and is attached to the drilling rig.

In Fig. 2, the set gripping devices 12 and 13 are shown by opening the gripping jaws one by one. In general, the opened second set gripping device and the rotating means 14 moved to engage the plug of the excavation pipe component can be plugged or excavated pipe component 8 without interference from engagement with the second set gripping device 13. ). After moving the digging pipe component in position A (instead of the lifting plug 25 in FIG. 1) to a position above the existing one, the digging pipe components are thus screwed together by means of rotation, resulting in peacetime Likewise, the connection is finally tightened to the rotor device 4. As a result, the excavation pipe can be lowered by stretching the lifting wire (of course the coupling is performed in the same way as the excavation pipe descends through drilling).

The result is that the excavation pipe is lowered down to the position shown in FIG. 1, whereby the next excavation pipe component is provided with an end portion protruding from the lifting plug 25 and the rotor device 4 above the excavation pipe component. And reach the position indicated by drawing number 8 '. This lifting plug will now be released from the excavation pipe.

The lifting plug 25 is a swivelling device, and therefore has two mutually rotating parts, as shown in FIG. 2, ie the engaging part 26, in the lower part of which the excavating pipe component and A lifting eye for providing a male thread 26 'at its free end in a direction opposite to the lifting portion 27 and for cooperating with the lifting wire as described above on the outermost side (a lifting eye) Is provided.

The rotating gripping unit of the gripping unit 11 comprises a drive roller 20 and has a surface with engaging means to ensure good engagement with the component being rotated. The drive motor 21 is aligned with those supported by a swing arm construction which is arranged on the side of the drive roller 20 in the example shown to support the rotating means 14.

When the gripper unit 11 is operated such that the rotating means 14 and the second set gripper 13 are axially displaced in the direction from the excavation pipe component 8, the drive rollers 20 are engaged. The rotation of the portion 26 enters rotation. The lifting plug 25 is moved axially in the direction from the excavation pipe component to be free. The lifting portion 27 is held simultaneously by the second set gripping device 13 to prevent unwanted rotation given to the lifting wire and to prevent rotation of the lifting portion.

Thus, the first set gripping device 12 grips the end portion of the excavation pipe component 8 ', while the rotating means 14 comes into contact with the engaging portion of the lifting plug 15, and the second set gripping device The device 13 comes into contact with the lifting portion 27 of the lifting plug 25, so that the release of the lifting plug 25 is performed through the rotation of the rotating means 14.

When the lifting plug 25 is released from the digging pipe component 8 '(FIG. 1), it is of the rotating unit 18 carrying the gripping unit 11 from the first position in the direction of the second position. It is rotated by operation. To allow this rotation, the first set gripping device 12 is opened while the rotating means 14 as well as the second set gripping device 13 are still engaged with the lifting plug 25.

3, the rotation unit 18 rotates the gripping unit 11 with the lifting plug 25 supported in the second position, and the gripping position 7 is connected to the rotating arm 7 connected to the storage 6 It is shown being aligned for cooperation with the excavation pipe component 8 supported by it. The determined position of the gripping unit 11 is ensured by a guide beam 19 forming a mechanical stop for the rotational movement of the gripping unit 11 in the second position.

Figure 3 shows that the pivoting arm 7 pivots around the second pivotal axis A2 to the delivery position, and correspondingly, the guide beam 19 is mechanically stopped for the pivoting movement of the pivoting arm 7 in the delivery position. It shows the wealth.

Appropriately at least one of the pivoting arm 7 and the gripping unit 11 is here a particular (not shown) abutment in the form of a metal plate in each distal position. elements, an abutment arm, or the like, and the abutment components (not shown) are conveyed against the position of the first and second rotational axes, respectively, for alignment contact with the guide beam provided appropriately. An example of a joint arm cooperating with a rotation unit 8 supporting the gripping unit 11 is shown in FIGS. 5A and 5B. At least one of the abutment component and the abutment means can be appropriately adjusted to adjust the alignment position by means of suitable distance adjustment means ((not shown)) known per se. The pivoting arm also has side alignment of the pivoting arm in the guiding position. There is a fork-shaped guiding element 30 for which the fork grips around the lateral edge of the guiding beam in the guiding position. The corresponding one is aligned to the guiding beam And, it may also be provided that the gripping device unit is respectively engaged with the corresponding guide component.

It should be noted that the first set gripping device 12 is in a position for gripping with the digging pipe component 8 when it has reached the delivery position. The end of the excavation pipe component 8 with the outermost male thread is now accessible for gripping by the gripping unit 11 in the delivery position.

The lifting plug 25 is simultaneously held by the rotating gripping unit and the rotating device 14 forming the second set gripping device 13 and is now ready to be screwed together with the digging pipe component 8.

For the purpose of compensating the thread pitch during screwing, the unit comprising the rotating means 14 and the second set gripping device 13 is axially displaced in the direction of the digging pipe component 8 in this case , The driving roller is rotated.

After the screwing of the male thread 26 'of the engaging portion 26 (see FIG. 2) from the excavation pipe component 8 to the male thread is completed, the first set gripping device 12 as well as the rotating means 14 ) And the second set gripping device 13 are opened. The digging pipe component 8 thus passes through the position shown by the dashed line 8 "and eventually ends at the position of the second digging pipe component along the " grip position axis " With the help of the lifting wire, it is free to be raised.

Against the end where the excavation pipe component 8 is screwed with the lifting plug, in the region of the second end, before being free from the gripper, it is attached to rotate on the gripper shuttle 40 It is gripped by a guiding gripper 41, which is adjusted by a hydraulic cylinder. Its embodiment is shown in more detail in FIG. 4. As a result, the pivoting arm 7 is lowered to the stowed position (in Fig. 1), which is off for movement of the gripper shuttle 40.

The guide beam 19 is provided with a longitudinal guide 42 for a gripping device shuttle 40 that is displaceable to drive. The pivot 43 has pivot axes that are essentially parallel to the first and second rotational axes A1, A2 which allow rotation in the same place, including the excavation pipe position and the delivery position.

After gripping the digging pipe component 8, it controls its movement during the lifting process and guides its free end to guide this free end aligned with the digging pipe position A in the drilling rig. The guide gripping device is aligned. With the operation of the guiding gripping device which grips the excavation pipe component and operates the gripping shuttle, the guiding gripping device is arranged to follow the rotational movement without being controlled to rotate itself. For the purpose of bringing the digging pipe component to the right position for gripping, on the one hand in the outermost position as shown in Fig. 3, on the other hand in the inner position adjacent to the transport beam, but the actuation rotation control is pivot ( It should be carried out with a guide gripping device around the axis of 43). This is suitably achieved by a gripping device shuttle provided with a rotating actuator for the guide gripping device 41, the rotating actuator operating between two end positions according to the above, a hydraulic cylinder or a type known per se. It may be in the form of another type of rotary actuator.

Referring again to FIG. 3, the gripper shuttle 40 with the guide gripper 41 is the first outermost part of the guide beam to grip there the first end portion of the digging pipe component 8 intended for lifting. In the first position (solid line) of the position, the other end portion of it is intended to be screwed with a lifting plug or the like to cooperate with the lifting winch.

In the intermediate position, which is more clearly shown in FIG. 7A, the gripper shuttle, indicated by reference numeral 40 '(in dotted lines in FIGS. 1 and 3), guides the excavation pipe component 8 ".

The gripper shuttle is also clearly shown in Fig. 7B, denoted by reference numeral 40 "(dotted line in Fig. 3) at the second position of the guiding beam close to the transport beam 2, at the second position. In the region of the pipe position it is aligned with the guide gripping device 41 to align with the gripped digging pipe component, that is, such alignment is typically aligned with the transport beam and the incoming inlet bottom end of the digging pipe component. It can be performed for an alignment aid (not shown here) that is movable back and forth for guidance.

The guide beam is preferably such that the first pivot axis L1 is coaxial with the first pivot axis A1 and is rotatably attached to the first pivot axis L1 in relation to the region of the first pivot axis A1. have. The guide beam 19 is also preferably such that the second pivot axis L2 is coaxial with the second pivot axis A1 and is associated with the second pivot axis L2 in relation to the region of the second pivot axis A2. It is attached to rotate. As a result, the guide beam after adjustment of the excavation device automatically has an appropriate direction when the support for the guide beam (such as the storage device 6) is fixed to the ground at the end facing from the transport beam, or a complicated measurement method or the like. When installing and relocating the rig in an easy way without the requirement of applying it, it has the required criteria for the stop of the rotational movement of the gripping unit as well as the rotational arm.

As is clearly shown in the figures, the rotating arm as well as the gripping unit rotates in the illustrated embodiment, and is parallel to a vertical plane or at least a plane comprising the axis of the excavation pipe position A or a plane thereof. In a flat plane, it rotates to the illustrated installation of the rock rig, whereby the axes A1 and A2 are (basically) horizontal. If there is a request to position the transport beam in an inclined position, of course, it is necessary that the axes a1, A2, L1, and L2 each have a corresponding inclination.

It is preferred to rotate the pivoting arm 7 in a vertical plane or in a plane comprising the axis of the excavation pipe position A of the excavator or in a plane parallel to such a plane until it reaches a position aligned with the guide beam. However, it is not excluded that the rotating arm has a coupling to the guiding beam that allows alignment in a change in which the rotating arm, for example, describes an alternative movement that combines horizontal and vertical rotational movement. Changes (not shown), for example with two pivot axes L2 ', L2 "extending at an angle with respect to each other, are also not excluded. For example, the loading position is different from that shown in the drawing for handling purposes. This may be of interest if it is desired to align.

After aligning and guiding the new digging pipe component, it can be screwed together with the digging pipe as described above.

So far, the operating function of the handling device according to the present invention has been described, for example, to lower the excavation pipe after exchanging a drill bit. During the holding of the excavation pipe, in other words, the reverse process is used in principle, screwing the lifting plug to the excavation pipe component in the position of the operating excavation pipe, and pulling up the lifting plug connected to the excavation pipe in one position, in principle used, itself known In the proposed method the rotor device is arranged to unthread the best excavation pipe component from the subsequent excavation pipe component.

As a result, the next excavation pipe component with the end portion has another lifting of the excavation pipe to locate itself in the position shown in Fig. 1, so that the gripping unit 11 comes in and rotates together with the means 14 The next excavation pipe for the purpose of alignment with respect to the best excavation pipe component gripping and rotating means 14 driven for controlled uncoupling of this excavation pipe component together with the first set gripping device 12. Hold the component ("the first").

The result is that the excavated pipe component thus released is gripped by the guide gripping device so that the lifting wire is loosened in a controlled manner so that the excavating pipe component finally reaches the delivery position and at the same time it is parallel to the working excavating pipe position. It is brought out through the movement of the gripping device shuttle 40 away from the transport beam 2 to come out of the position. The lifting plug here can be gripped by the gripping device of the gripping unit 11 for uncoupling the latter. When the lifting of the pivoting arm 7 for receiving the digging pipe component has now occurred and the screw disengagement is completed, the pivoting arm can be lowered for transporting away from the digging pipe component supported by the storage device or the like. have. So the process can be repeated as many times as necessary.
