Definitions
- the invention relates to a handling device for drill pipe in deep wells, z. B. for oil and Erdgasexploration.
- a handling device for drill pipe in deep wells, z. B. for oil and Erdgasexploration.
- the term "pipe handler” has prevailed in specialist terminology and accordingly, the term “pipe handler” is used interchangeably with the term “handling unit for drill pipe” in the following.
- a pipe handler is part of a so-called top drive, that is to say the drive unit which is vertically movable in the mast of a drilling rig and which rotates with a drive unit, usually an electric motor, which rotates the drill pipe for the drilling operation.
- the Topdrive is divided into a fixed and a rotatable unit for this purpose.
- the fixed unit comprises the drive unit.
- the rotatable by the drive unit element is the pipe handler.
- the aggregates of the pipe handler are supplied via a hydraulic rotary feedthrough between the fixed and rotatable part of the top drive, namely by pressure cylinders and the like are supplied with a hydraulic fluid with a pressure, for example, to move so-called elevator hoop or to activate a provided on a so-called Torquearm holding forceps for drill pipe.
- a certain amount of drill pipe elements is normally stored for storage vertically beside or on the mast of the rig and for this purpose a so-called finger platform is provided which is located on the mast in the region of the upper end of the stored drill string elements.
- An additional or alternative storage position for at least one drill string element is the so-called mouse hole. So far, the removal of drill string elements from its storage position or the reverse path, namely the deposition of drill string elements in a storage position, by manual control.
- the Topdrive is moved to a corresponding vertical position in the mast, which allows removal or removal of drill string elements. As soon as the Topdrive is in this position, the or each elevator bar is pivoted and a drill pipe element is picked up or stored with the boom elevator.
- DE 10 2009 039 022 A in view of a hitherto existing problem that it was essentially the attention of the operating personnel to perform necessary control operations for initiating and completing such handling operations, devices and methods have been proposed with which a fully automatic monitoring the pipehandler and / or the topdrive with pipehandler is possible.
- a possibility for detecting a position of the at least one elevator bracket is specified.
- DE 10 2009 039 022 A is expressly incorporated in the disclosure of the present specification, e.g. with regard to the electrical and hydraulic supply and control of the top drive explained there. Further, but only to the extent of general technological background relevant prior art results from US 4,326,745 and US 4,800,968.
- An object of the invention described below is to provide a further embodiment of means for detecting a position of the at least one elevator bracket.
- the or each valve acts as a means for detecting the position of the or each elevator bracket and is part of a hydraulic shift control circuit continuing outside the handling unit.
- the at least one gate is provided for the at least one valve, wherein the or each valve opens the hydraulic shift control circuit at a first position or position of the gate and wherein the or each valve at a second position or position of the gate hydraulic
- Switching control circuit closes.
- a position information with respect to a deflection of the at least one elevator bracket is given based on the closed or open hydraulic shift control circuit.
- An advantage of the invention is that only one valve or a group of valves, for example two valves, and the part of a hydraulic switching control circuit is required as means for detecting a position of the at least one elevator bracket on the side of the handling unit in which the or every valve is located.
- the handling unit / the pipe handler is the rotatable part of a top drive and for decoupling between the rotatable and the fixed part, a rotary feedthrough is provided.
- the hydraulic switching control circuit can be guided via this rotary feedthrough.
- the hydraulic switching control circuit is thus very simple and the or each Valve of the handling unit causes a transmission of a position or position of the respective link and thus a transmission of an underlying deflection of the at least one electric umbel in a state of the hydraulic switching control circuit.
- a simple switching control circuit can be, for example, pressure losses or the like, which can influence or distort a detection of the position of the at least one Elevatorbügel well.
- the or each respective associated movable gate and the switching control circuit influenced thereby a subsequently also referred to as zero position neutral position of the or each Elevatorbügels be detected.
- the zero position of the or each elevator bracket is a position in which the elevator bracket usually hang vertically, at least one position of the elevator bracket in which a vertical topdrive method in the drilling mast is possible without causing collisions, in particular of the or each elevator bracket or the tilt arm Parts of the drilling mast or objects located there can come.
- Position or deflection is referred to below as a collision-free position.
- the or each link is rotatable with an axis and that acts as a backdrop at least one attached to the axle cam.
- the respective valve has a role that on the surface of the
- a position of the tilt arm is also a measure of a position of the or each elevator bracket, finally, the position of the gate, so in particular a rotational position of the gate, a measure of the position of the or each elevator bracket.
- a first position or position of the gate is given when facing the rotatable gate of the coinciding with the circular envelope contour portion of the valve.
- a second position or position of the gate is given when a founded from the circular envelope contour of the backdrop section facing the valve.
- Such a foundedicide section acts like an inverse cam and a provided at a rotatable gate on the valve roller or the like falls basically in the recess thus formed in the backdrop, so that the or each valve in such a second position or position of the scenery hydraulic Switching control circuit closes.
- the section coinciding with the circular envelope contour of the slide will be referred to as the first radius of the slide and the second radius of the guide will be referred to the section set back from the circular envelope contour of the slide.
- the second radius is smaller than the first radius.
- the first position or position of the backdrop thus affects the larger, first radius and in the second position or position of the backdrop acts according to the smaller, second radius.
- the valve remains open.
- the second radius is effective, the valve closes.
- the handling unit is provided that function as a backdrop two combinable and on the common axis relative to each other rotatable cams.
- Each of these cams has a section with a first radius and a section with a second radius.
- an off-center position of the or each elevator bracket can be defined as zero position.
- the cam or two mutually relatively rotatable cams allow the specification of a position range.
- a section of forty angular degrees or approximately forty degrees of angularity can thus be defined as a permissible area due to a minimal overlap of the second radius segment. If the cams are rotated in the direction of a lesser overlap, this range is reduced, so that also allowable ranges of less than twenty angular degrees can be defined.
- By also being able to releasably lock two mutually relatively rotatable cams on the axle it is possible, for example with a width of a permissible range of seven degrees of angle with respect to an actual deflection of the or each elevator bracket, to set that for example, minus two to plus five degrees are allowed.
- the chain and the pinion result in an over or under reduction of the movement of the tilting arm, so that, for example, with a rotatable link, the permissible range of motion the Tiltarms on the complete outer periphery of the backdrop or at least almost the entire outer periphery of the backdrop can be displayed.
- This allows an even more accurate and finer detection of a zero position or at least a collision-free deflection of the or each elevator bracket.
- a chain segment is attached to the tilt arm such that the pinion can engage in it and that movement of the tilt arm results in rotation of the pinion.
- a chain is optionally also a rack or the like into consideration.
- a chain is particularly suitable for attachment to the relevant portion of the tilt arm, because the mobility of the chain links immediately follows the chain section of a predetermined contour, which is otherwise formed so that a distance between an axis on which the pinion is located, and the individual chain links regardless of a pivot position of the tilt arm remains the same.
- this effect can be achieved, for example, with a curved rack instead of the chain section.
- a particular embodiment of the handling unit is characterized in that two valves and two synchronously movable scenes, ie in each case a gate for each valve are provided.
- functional safety which is categorized in technical terminology as so-called safety integrity levels (SIL), this makes sense.
- the two valves are redundant. If a single valve fails in the form of a leak, pressure would no longer build up in the hydraulic switching control circuit. If the failure of a valve expresses itself to be closed, then due to the parallel connection of both valves, the redundant valve is sufficient to generate a pressure drop in the hydraulic switching control circuit and on this basis to enable the generation of a corresponding signal.
- the two valves provided for each one valve scenes are moved synchronously in two valves, a possibility of error in terms of position detection is limited to the valves.
- the invention described herein is also a top drive with a base part and a rotatable part on the base part, wherein as a rotatable part a handling unit as described here and described below, wherein the hydraulic shift control circuit via a hydraulic rotary feedthrough from the rotatable part extends to the base part and wherein at the base part at least one pressure sensor for detecting a pressure in the hydraulic switching control circuit and for outputting a related sensor signal is located.
- the base part When, in the case of a top drive, the base part is in a hydraulic power circuit for controlling at least one hydraulic cylinder acting as an actuating element (link tilting).
- Cylinder as a means for detecting the position of the or each elevator bracket is a volumetric flow sensor for detecting a volume flow in the hydraulic power circuit and to deliver a related sensor signal, not only a possible zero position of the or each elevator bracket, but also a respective deflection / pivot position can be detected.
- a detection of a pivot position of the or each elevator bracket is useful if, for example, automatically certain deflections of the or each elevator bracket to be retrieved. This is described in the above-mentioned DE 10 2009 039 022 A, which to this extent is included in the disclosure content of this description in order to avoid repetition.
- the detection of certain pivotal positions of the or each elevator bracket is also required when it comes to the range of motion of Topdrives in the drilling mast an imaginary envelope surface ("Envelope") to pull to which the or each elevator bar may be pivoted maximum
- envelope imaginary envelope surface
- a control device which can be located on the top drive or, for example, also remote from the top drive can be fed as input signals the sensor signal available from the or each pressure sensor and the sensor signal available from the volumetric flow sensor, that based on the volume flow sensor a position information with respect to a position of the at least one Elevatorbügels can be generated and that the position information can be calibrated on the basis of the sensor signal available from the pressure sensor.
- a control device which can be located on the top drive or, for example, also remote from the top drive can be fed as input signals the sensor signal available from the or each pressure sensor and the sensor signal available from the volumetric flow sensor, that based on the volume flow sensor a position information with respect to a position of the at least one Elevatorbügels can be generated and that the position information can be calibrated on the basis of the sensor signal available from the pressure sensor.
- Flow sensor due to the volume flow detected in each case can result in longer operation.
- the position information based on the sensor signal available from the pressure sensor, so to speak on the basis of a zero position of the or each Elevator lever indicating signal, calibrated, in particular set to zero any errors in the volume flow detection are limited to each individual pivoting operations, so that already systematically a limitation of errors and, above all, any errors do not sum over a plurality of panning operations.

- the top drive 16 comprises a fixed part 26 and a rotatable part 28.
- the fixed part 26 comprises the drive for moving the rotatable part 28, for example in the form of a motor.
- the fixed part 26 of the top drive 16 is also referred to as the base part or drive unit and means fixed that it is the non-rotatable part of the top drive 16, which is vertically movable in total in the guide rails 24.
- the rotatable part 28 of the top drive 16 is referred to in the technical terminology and accordingly also as a pipehandler and comprises at least one pivotable elevator bracket 30 and at least one actuating element 32 for effecting the pivoting operation of the or each elevator bracket 30.
- two elevator bracket 30 are present and The description will be continued below without departing from any further generality with respect to two elevator hanger 30.
- the elevator bars 30 are oriented substantially vertically, ie the elevator bars 30 hang vertically downwards. At least in such a position, a vertical movement of the top drive 16 on the guide rails 24 in the mast 10 is possible without the risk for a collision with parts in or on the mast 10 to be obtained for the elevator hoop 30, for example with the finger stage 14 (FIG. 1) or one of the Such a rest position is an example of a zero position of the elevator bracket 30, at least one example of a collision-free position of the elevator bracket 30.
- the actuator 32 does not act directly on the elevator bracket 30, but first on a so-called Tiltarm 34, which in turn acts on the buckles 30, so that a triggered by the at least one actuator 32 pivoting the tilt arm 34 pulls a pivoting of the elevator bracket 30 by itself.
- Actuator 32 is often referred to in technical terminology as Tiltzylinder.

- the reference numeral 42 denotes means for detecting a position of the at least one elevator bracket 30. This will be explained below with further details.
- Fig. 3 shows first a hydraulic equivalent circuit diagram. The horizontal in the middle of the representation drawn
- Dividing lines denote the hydraulic rotary feedthrough 40. All the elements shown in FIG. 3 above the hydraulic rotary feedthrough 40 are located in or on the rotatable part 28 of the top drive 16, ie on the pipe handler. On the left is shown with the pipehandler actuators 32, so the tilt cylinders, a hydraulic power circuit 44. Part of the hydraulic During operation, the volumetric flow sensor 46 detects a volumetric flow in the hydraulic power circuit 44 and thus when controlling at least one tilt cylinder functioning as the actuation element 32 is a measure for a pivoting position of the elevator arch 30. The volume flow sensor 46 is thus adjacent to those below
- the hydraulic power circuit 44 can be fed directly from a hydraulic unit or diverted from a valve block 48. At a branch of a valve block 48, the pivoting of the elevator bracket 30 can be influenced by a suitable control of the outputs of the valve block 48.
- FIG. 3 shows, as a means 42 (FIG. 2) for detecting the position of the elevator hanger 30, two valves 50 connected in parallel hydraulically.
- a plurality of valves 50 are required to fulfill a certain safety level (SIL). Basically, a valve 50 is sufficient. This also applies to all elements described below as being duplicated, and the description will be continued in accordance with the pictorial representations which show an embodiment for the increased security level, that is to say an embodiment with redundant units, but without departing from any further generality.
- Each valve 50 is guided in a movable with a movement of the tilt arm 34 slide 52. At a first position or position of the gate 52, each valve 50 opens a hydraulic
- Shift control circuit 54 in which the valve 50 acts as a switching element. At a second position or location of the link 52, each valve 50 closes the hydraulic shift control circuit 54.
- the hydraulic switching control circuit 54 extends from the pipe distributor with the two valves 50 via the hydraulic rotary feedthrough 40 and settles outside of the
- At least one pressure sensor 56 here two pressure sensors 56, are provided, which are coupled via a distributor block 58 to the hydraulic switching control circuit 54. Downstream of the manifold block 58 are located the following optional units: a flow control valve 60, a reservoir 62, a check valve 64, and a pressure control valve 66.
- valves 50 close the hydraulic switching control circuit 54, a pressure builds up between the valves 50 and the pressure regulating valve 66, which pressure can be sensed by the pressure sensor 56.
- the optional flow control valve 60 prevents excessive pressure loss in the rest of the system. With the hydraulic unit off or system pressure low, the accumulator 62 maintains the pressure between the valves 50 and the check valve 64.
- a position of the valves 50 can be sensed, wherein on the movable with a movement of the tilt arm 34 scenes 52 detecting a position of the valves 50 corresponds to a detection of a position of the at least one elevator bracket 30.
- the or each valve 50 closes the hydraulic Wegsteu- circuit 54, so that this is sensed by the two pressure sensors 56 as pressure in the range of a predetermined or predetermined magnitude in the hydraulic Weg Kunststoffries 54 ,
- FIG. 5 shows, in a side view from the device according to FIG. 4, only the unit which can also be labeled as a camshaft with the cam disks 70, 72.
- the cam disks 70, 72 it can be seen that these each have a circular envelope contour.
- Section of the cam 70, 72 which coincides with its circular envelope contour, as a portion with a first radius and the portion of the cam 70, 72, which is set back from the circular envelope contour, referred to as a portion with a second radius or inverse cam ,
- FIG. 6 shows a section through the camshaft from FIG. 5 along the section line labeled AA. It can be seen the axis 78 and provided for driving the axle 78 and thus a total of the rotation of the camshaft 74 provided pinion.
- This has in each case left and right on a matching curve geometry, namely the curve writing 70.
- This match the curve geometry also applies to the two second cams so that the valves 50 switch synchronously.
- One of the two second cam disks, namely the second cam disk 72 facing away from the pinion 74, can also be locked to the axle 78 with a corresponding screw-actuated clamping connection.
- the second cam 72 facing the pinion 74 is screwed to the other second cam 72 remote from the pinion 74 with the aid of spacers 80 and associated screws, in order to ensure that both valves 50 always synchronize synchronously even after adjustment of the second cam discs 72. It is advantageous that the two first cams 70 remain movable 72 between the two second cams 72 even after screwing the two second cams 72. Thus, the respective end points of the inverse cam of the backdrop can be set separately, without always having to solve both cam pairs 70, 72 simultaneously.
- FIG. 7 shows the relationships according to FIG. 6 in an isometric view. Visible are the cams 70, 72, the pinion 74 and the axis 78. With regard to the screw 80 it can be seen that a slot is provided for this in the inner cam 70 through which they pass, so that the slot on the one hand a rotation of the both cams 70, 72 allowed relative to each other, but on the other hand also limits the scope of such twistability.
- each position or position of the link 52 in which the roller 68 of a respective valve 50 bears against the outer peripheral surface coinciding with the circular envelope contour of at least one of the two cams 70, 72, a first position or position of the thus formed link 52, in which the hydraulic shift control circuit 54 is open.
- An opening of the valve 50 or one of the valves 50 thus causes a sensible with the pressure sensor 56 or two pressure sensors 56 pressure loss in the hydraulic shift control circuit 54 and such pressure loss shows, because the cam 52 formed by the cam plates 70, 72 with a movement of the tilt arm 34th is movable, a position of the or each elevator bracket 30 at.
- FIG. 8 shows an enlarged view of the pipe handler, that is to say of the rotatable part 28 of the top drive 16 with elevators 30 (slightly deflected slightly out of the vertical) (only one recognizable).
- This position of the elevator bracket 30 is replaced by a corresponding Position of the tilt arm 34 causes, in turn, by the at least one actuating element 32, so the or each tilt cylinder, is moved.
- this movement of the tilt arm 34 causes a rotation of the camshaft (FIG. 7) and a rotation of the slotted links 52 formed there by the respective pair of cam plates 70, 72.
- FIG the situation corresponding to the position of the tilt arm 34 in FIG. 8. It can be seen that the two rollers 68 of the valves 50 are already located on the links 52 in a region in which their outer contour coincides with a circular envelope contour, and open the valves 50 corresponding to the hydraulic switching control circuit 54. This decreases in the hydraulic
- Switching control circuit 54 a with the or each pressure sensor 56 sen- sizable pressure that can be evaluated based on a sensor signal generated by each pressure sensor 56 as position information with respect to a position of the or each Elevatorbügel 30, here so as position information indicating that the Elevatorbügel 30 not in a position defined as zero position.
- Fig. 9 and Fig. 10 show in comparison to the situation in which the elevator bracket 30 hang substantially vertically, with an associated position of the tilt arm 34 and caused by the chain 76 and the pinion 74 rotation of the scenes 52, so the cure - Venusionn 70, 72, cause the rollers 68 of the valves 50 just enter the inverse cam of the link 52.
- the valves 50 are in this position unconfirmed and thus close the hydraulic switching control circuit 54, so that via the pressure sensors 56, a resulting pressure in the hydraulic switching control circuit 54 is sensed and a resulting sensor signal as position information, here as position information that the or each elevator bar 30th is in its zero position, is evaluable.
- the sensor signal generated by the pressure sensor 56 thus indicates the zero position of the or each elevator arm 30 only at a sufficient operating pressure in the hydraulic shift control circuit 54 and at a corresponding position of the slide 52 / scenes 52. Any other position of the link (s) 52 will result in a changed sensor signal as will any pressure loss in the hydraulic shift control circuit 54 ("depressurized open") due to an error situation
- Zero position signal means that the or each elevator bar 30 is either not in zero position or that there is otherwise an exceptional situation
- the zero position signal or the absence of the zero position signal can be evaluated by a control device, such that a vertical movement of the top drive 16 in the drilling mast 14 is only possible Conversely, a vertical movement of the top drive 16 can be stopped immediately if the zero position signal eventually disappears.
- a control device of the type just mentioned so for example a programmable logic controller or in
- Hardware implemented functionality can also link the zero position signal of the or each pressure sensor 56 with a position signal that can be generated by the volume flow sensor 46, such that a position signal generated or influenced by the volume flow sensor 46 is calibrated with each zero position signal, for example, back to zero.
