Definitions

  • the invention relates to a working machine, in particular a construction machine, with a mast, along which a top drive can be moved vertically by means of an adjusting device, through which a telescoping Kelly linkage with at least two Kelly bars is displaceably guided, with an outer Kelly bar, which is designed to rest on the top drive, and an inner kelly bar are provided, which includes a cable suspension for a cable, through which the inner kelly bar can be moved vertically by means of a main cable winch, with kelly bars on their outer and/or inner sides for torque transmission with axially running driver strips and locking pockets on the driver strips and/or axial locking elements are provided, which can be moved into the locking pockets for axial locking of the Kelly bars or extended out of the locking pockets for unlocking, according to the preamble of claim 1.
  • the invention further relates to a method for working a soil with a working machine, with a mast, along which a rotary head is moved vertically by means of an adjusting device, through which a telescoping Kelly linkage with at least two Kelly bars is displaced and guided, with an outer Kelly bar, which is mounted on the Top drive can rest on it or can be locked with it, and an inner kelly bar is provided, which is suspended on a cable, through which the inner kelly bar is moved vertically by means of a main cable winch, the kelly bars on their outer and/or inner sides with axially running torque transmission Provide entrainment strips and locking pockets on the entrainment strips and/or axial locking elements which are retracted into the locking pockets for axial locking of the Kelly bars or extended out of the locking pockets for unlocking, according to the preamble of claim 9.
  • a kelly linkage is a telescoping tool linkage which is constructed from a plurality of tubular rod elements and has at least one outer kelly rod and one inner kelly rod.
  • the inner kelly rod and thus the kelly linkage as a whole is suspended from a cable, the kelly linkage being guided by a kelly guide and/or an annular rotary drive, also known as a top drive.
  • Torque can be transmitted from the rotary drive via the Kelly linkage to a soil cultivation tool, in particular a drilling tool, which is attached to the lower end of the inner Kelly rod. Greater drilling depths can also be achieved by telescoping the individual Kelly bar elements to one another.
  • the individual Kelly bar elements have axially extending stop strips on their outside and inside, which are used for torque transmission.
  • locking pockets or locking elements are provided at certain axial positions, in particular at a beginning and end area, through which the Kelly bar elements can be fixed axially to one another. In this way, axial compressive forces can also be applied to the Kelly linkage and thus to the tillage tool via the auger drive.
  • the outer kelly rod can also be fixed axially to the drill drive.
  • the drilling bucket has to be repeatedly moved into and out of the drilled hole.
  • the Kelly rod is repeatedly telescoped in and out.
  • the drill bucket After the drill bucket has been filled with excavated soil material, it must be pulled out of the drill hole to be emptied. To do this, it is necessary to unlock the individual Kelly bar elements again and move them into one another.
  • the Kelly linkage can be pulled out together with the drill bucket pulled out of the well and pivoted to an emptying position. Then, for a further drilling step, the drilling tool is again retracted into the borehole with renewed telescoping of the Kelly rod.
  • a method of monitoring a Kelly drill string is known from US Pat DE 10 2012 019 850 A1 known. With this known method it is necessary to detect a rotational position of the rods. This requires a complex sensor arrangement, which is fundamentally error-prone in rough drilling operations.
  • a drill operator may ascertain a correct locking condition of a Kelly linkage for safe drilling operation. This can be done via a visual inspection of the Kelly linkage or a manual test operation, which is time-consuming and does not exclude the risk of incorrect assessment, at least for inexperienced drill drivers.
  • the invention is based on the object of specifying a working machine and a method for working a soil which enable particularly efficient and safe working with a Kelly linkage.
  • the work machine according to the invention is characterized in that a control is provided which is designed to automatically check that the Kelly bars are correctly locked, independently of the implementation of a locking process, the control device for the top drive and/or the cable winch being able to be actuated, see above that the Kelly bars are moved axially relative to one another, that at least one detection device is provided with which a travel path of the Kelly bars relative to one another and/or an axial force during the travel of the Kelly bars can be detected, and that the control is designed depending on the detected travel path and/or the detected axial force to determine the correct locking status of the Kelly bars.
  • a work machine is created in which the locking state of a Kelly linkage can be reliably checked at any time, independently of the execution of a locking process by the machine operator. This does not require a visual inspection or any special experience on the part of the machine operator.
  • a simple actuation of the control automatically carries out a test procedure in which the Kelly bars are moved axially to one another. If the Kelly bars are in a locked state, the locking element and the locking pocket must hit each other axially within a maximum possible axial travel path, which also results in an increase in the tensile force on the cable and/or the axial pressure on the top drive. If such a state of the axial movement and/or an increase in the axial force is detected by the controller, a correct locking state is recognized. If this does not happen, it can be determined in the opposite way by the controller that there is no correct locking.
  • a check of the locking state of a Kelly linkage can be automated and designed to be process-reliable.
  • a machine operator can be relieved of this activity, with the risk of incorrect judgment by a human being being eliminated.
  • Overall, such a drilling method can be carried out efficiently and particularly reliably.
  • a preferred embodiment of the working machine according to the invention consists in that a limit value for a maximum travel distance and/or a limit value for a minimum axial force is stored in the controller and that the detected travel distance with the maximum travel distance or the detected axial force is used to determine the locking state is comparable to the minimum axial force.
  • the maximum travel is typically a few centimeters per locking point and is largely determined by the difference between the axial length of the locking pocket and the axial length of the locking element screwed into it. In particular, the maximum travel distance depends on the number of locking pockets, so that a total travel distance of up to more than one meter can result with multiple Kelly bars.
  • the limit or threshold for the minimum axial force depends on the usual displacement forces. If the locking element and the locking pocket strike each other axially, further axial movement is blocked and there is an increase in force on the drive element, which causes the axial movement. This can be determined in particular by force-measuring elements, for example on the main cable winch or an actuating cylinder, or by an increase in pressure in a hydraulic drive system.
  • the Kelly linkage consists of only two Kelly bars, namely a tubular outer Kelly bar and an inner Kelly bar arranged displaceably therein.
  • the Kelly linkage has one or more intermediate Kelly bars, which are arranged between the outer Kelly bar and the inner Kelly bar.
  • Kelly linkages with three to five Kelly rods are particularly preferred.
  • the work machine according to the invention with the Kelly linkage can be used for a wide variety of activities.
  • a drilling tool in particular a drilling bucket or an auger, to be detachably attached to the lower end of the inner kelly rod.
  • drilling tools can be used for discontinuous drilling, in which a Kelly rod must be repeatedly extended and retracted.
  • the top drive can be actuated by the controller when the Kelly bars are moved, with a predetermined torque being able to be exerted.
  • a torque is exerted on the Kelly bars in such a way that the locking element is reliably screwed into a locking pocket. In this way, it can be ensured that when a locking state is present, the locking element and the locking pocket meet as extensively as possible.
  • the travel distance and the axial force can be determined using appropriate displacement sensors or force sensors.
  • a particularly efficient determination of the axial force can be achieved in that an increase in pressure in a hydraulic drive system can be detected in order to detect the axial force.
  • a check of the correct locking status of a Kelly linkage can be carried out by the machine operator if necessary or at specified times or operating states. According to a further development of the invention, it is particularly expedient here for the position of the actuating device and/or a position of the cable to be able to be stored in the control device when the locking state is detected. This collected data can be used to calibrate the Kelly linkage and verify the positions of the latches.
  • a further preferred embodiment of the invention consists in that at least one input and/or determination device is provided with which a type and/or size of the Kelly linkage, a position of the actuating device for the top drive and/or a position of the cable can be entered.
  • an input can be made via an input terminal.
  • they can Positions are automatically detected by sensors.
  • the method according to the invention is characterized in that a locking state of the Kelly bars is automatically checked by means of a controller, the actuating device of the top drive and/or the main cable winch being actuated by the controller, so that the Kelly bars are moved axially relative to one another, that by means of at least one detection device a travel path of the Kelly bars relative to one another and/or an axial axial force during the travel of the Kelly bars are detected, and that a locking state of the Kelly bars is determined by the controller as a function of the detected travel path and/or the detected axial force.
  • the adjusting device can in particular be a feed drive of a feed carriage, on which the top drive is arranged and with which it can be displaced along a mast.
  • the feed drive can in particular have a hydraulic cylinder or a cable winch.
  • the method according to the invention can be carried out, in particular, with a work machine as described above. Accordingly, the advantages described above can be obtained.
  • An advantageous variant of the method of the invention is that for locking and/or unlocking a soil working tool on the Kelly linkage is placed on the ground, in particular on the bottom of a borehole.
  • the outer kelly bar and/or an intermediate kelly bar according to the invention can now be moved relative to the inner kelly bar until the testing process is completed.
  • the method according to the invention can be used in any application in which a tool with a Kelly linkage is required.
  • a borehole is created in the ground.
  • the creation of the borehole can be carried out by excavating the soil material.
  • the borehole is filled to form a foundation element.
  • the foundation element can be filled with a pourable material, such as sand or gravel. It is preferred that the foundation element takes place by filling with a hardenable mass, in particular a concrete material.
  • an efficient operating sequence can be achieved in that the controller carries out an automatic locking process if no locking state has been determined.
  • the Kelly bars can be axially moved and rotated relative to each other in a defined manner, as is generally known for automatic locking.
  • the work machine 10 each has a substantially vertical mast 12, which each has an only in 1 shown masthead 14 has.
  • a Kelly linkage 40 is suspended vertically displaceably along the mast 12 via a cable 52, which is driven by a main cable winch 50 and guided via deflection pulleys 16 on the mast head 14.
  • the Kelly linkage 40 is according to the two embodiments according to figures 1 and 2 each with an upper outer kelly bar 42, a lower inner kelly bar 46 and an intermediate kelly bar 44 arranged in between educated.
  • a cable suspension 48 is provided at the upper end of the inner Kelly bar 46, on which the cable 52 for the vertical displacement of the inner Kelly bar 46 and also the further tubular Kelly bar elements is formed.
  • the outer kelly rod 42 has a bearing collar 43 at its upper end, with which the outer kelly rod 43 rests on a top drive 30, ie an annular rotary drive.
  • a damping device 32 with springs is arranged to dampen shocks between the top drive 30 and the support collar 43 .
  • the top drive 30 on a carriage 18 and thus the outer kelly rod 42 can be moved vertically along the mast 12 via an adjusting device 20 .
  • the adjusting device 20 is in accordance with the embodiment figure 1 designed as a hydraulic cylinder.
  • driver strips 66 are arranged on the outer kelly rod 42 on its outside, as shown in FIG figure 2 can be seen.
  • Corresponding driver strips 66 or locking elements are also arranged in a known manner on the other outsides and insides of the other Kelly bar elements.
  • a peg-shaped connecting element 49 is provided on an underside of the inner kelly rod 46, with which a soil cultivation tool 36 can be attached in a rotationally fixed manner.
  • the tillage tool 36 is in the embodiments according to figures 1 and 2 designed as an auger.
  • a simple kelly linkage 40 having an outer kelly bar 42 and an inner kelly bar 46 is shown.
  • the outer kelly rod 42 has at least one locking element 62 on its inside, which bears against an axially running driver strip 66 on the outside of the inner kelly rod 46 in the circumferential direction.
  • the locking element 62 on the outer kelly rod 42 can be pressed slightly against the driver strip 66 by means of a controller by applying a slight torque via the top drive 30.
  • the outer kelly rod 42 and the inner kelly rod 46 can now either have the Adjusting device 20 or the main cable winch 50 or both are moved axially to one another.
  • the outer kelly rod 42 with the locking element 62 rotates counterclockwise in the circumferential direction into the locking pocket 68 when it reaches a locking pocket 68, which is designed as an axial recess in the driver strip 66 in the illustrated embodiment.
  • This results in a twisting between the outer kelly rod 42 and the inner kelly rod 46 which can be detected via a first detection device, in particular a sensor device, as an indication of locking.
  • a correct locking state can be checked automatically at any time by means of the controller.
  • the actuating device 20 and/or the main cable winch 50 with the cable 52 are actuated via the controller in such a way that a defined axial movement of the outer kelly rod 42 in relation to the inner kelly rod 46 takes place.
  • the block-like locking element 62 must hit an axial stop 69 of the locking pocket 68 at least after a certain maximum axial travel, which is usually a few centimeters per locking point and in any case does not exceed the axial length of a locking pocket.
  • Further axial movement of the outer kelly rod 42 is now no longer possible.
  • this leads to an increased expenditure of force, which can be detected as an increase in pressure in the hydraulic system by which the axial drive element is driven. This can be detected by the controller, which then indicates that a correct lock has passed.
  • the controller can be actuated by the drill driver at any time, so that he is always reliably informed about the correct locking status. If no locking is detected, the controller can preferably carry out an automatic locking process.
