Definitions
- the present invention relates to a method for lifting a drill rod attached to a drilling device according to claim 1 and a drilling device with a controller for carrying out such a method.
- special safety devices can be used, which usually include a counter-element moved along with the Kelly bar and an associated weight arranged on the traction cable.
- the height of the weight on the mast or pull rope defines the maximum possible height of the swivel. Upon reaching this At maximum height, the limit switch contacts the weight, stopping the winch and ending the kelly bar lifting motion.
- the maximum possible drilling depth of such drilling equipment is typically determined by the length of the drill pipe or the Kelly bar that can be installed.
- the maximum length of the Kelly bar is in turn defined by the maximum possible height of the swivel relative to the drill and thus by the switching point of the limit switch and the position of the weight.
- the switching point of the hoist limit switch normally also takes into account a braking distance of the Kelly bar after the winch stop signal, in that the weight is attached at a certain safety distance from the gallows. This safety distance must be large enough to allow braking from the highest lifting speed or the maximum turning speed of the Kelly winch without colliding with the gallows.
- This X dimension is important to determine what lengths of support tube can be used or whether the bottom of a drill bucket can be opened.
- U.S. 2005/114001 A1 discloses a drilling rig in which a pulling means is automatically braked and/or stopped when it reaches a certain area below the masthead.
- the object of the present invention is to optimize said X dimension without having to make modifications to the drill or drill rods.
- this object is achieved by a method having the features of claim 1 and by a drilling device having the features of claim 11.
- the drilling pipe when the defined height of the drill pipe is reached, the lifting process is not completely aborted, but after the lifting movement has been braked, the drill pipe is lifted beyond the defined height within the safety distance.
- the drill pipe can be raised higher than in conventional systems, in which the safety distance only serves as a "dead" buffer for the braking distance of the drill pipe, but is not available for targeted positioning of the drill pipe.
- the maximum possible height of the drill string and thus the X dimension of the drill can be increased without any mechanical modification of the drill or drill string having to be made.
- the invention makes it possible to use a longer drill rod and thereby increase the maximum drilling depth.
- the step of controlling the winch to slow down the hoisting movement of the drill string may include a full deceleration to a standstill of the drill string, i.e. a full winch stop.
- the drill pipe can be raised further by operating the winch. This can be done automatically or manually by an operator, for example, and in particular at a lower speed.
- said step may be, taking into account certain measured and/or calculated data, decelerating the lifting speed to a lower speed, resulting in a smaller braking distance, the continued lifting now taking place at this lower speed. It is also conceivable that a dynamic control or regulation of the winch takes place, so that the continued lifting does not take place at a constant (lower) speed, but that the deceleration process is extended to virtually the entire additional specified or specifiable distance and the drill string at the end of this distance comes to a standstill.
- the additional distance available may be set to a fixed value, which is ideally as close as possible to the position at which a gallows collision occurs. As a result, the maximum additional height available due to the safety distance is optimally utilized.
- the value of the additional distance can be defined by the operator, with the value of course not being able to exceed the safety distance.
- the braking and/or the continued lifting of the drill string takes place taking into account the safety distance.
- the corresponding value can be stored, for example, in a control unit or controller or in a memory to which the controller has access.
- the developed length of the traction element is detected by means of a traction element length detection device when the defined height of the drill rod is reached, with the braking and/or the continued lifting of the drill rod taking into account this value of the developed traction element length when the defined height of the drill rod is reached.
- the measurement of the unwound pulling length is representative of a certain height of the drill pipe, whereby the absolute value of the height at a certain pulling length does not have to be known / calibrated.
- the measured value of the length of the traction element when the defined height is reached can be stored or made known to a controller and used as a calibration, so that the further values of the length of the traction element measured during continued lifting can be converted into a distance/height covered.
- the traction element length detection device can be arranged on or in the area of the winch.
- the length of the traction element currently being processed is detected by means of a traction element length detection device, with the braking and/or the continued raising of the drill string taking into account the length of the traction element that is currently being processed.
- the value of the current length of the traction device can be used to regulate the winch for braking the drill string so that it comes to a standstill exactly at the end of the defined or definable distance.
- the current distance covered or lifted by the drill string beyond the defined height is calculated from the current traction element length and the traction element length when the defined height is reached, and is compared with the value of the safety distance, with the braking and/or the continued Raising the drill string is done taking into account the result of this comparison. This ensures that the winch is stopped in good time before the safety distance is reached and the lifting process of the drill pipe is terminated so that no collision with the boom and thus damage can occur.
- All the parameters described above i.e. the length of the traction device when the defined height is reached, the current length of the traction device, its conversion into a height currently covered (absolutely or relative to the defined height) and/or the safety distance can be displayed to the operator using a visualization device.
- Optical and/or acoustic warning signals can also be output when one or more of these values are reached, exceeded/fall below or approached.
- the lifting speed of the drill pipe is detected by means of a speed measuring device and that when the defined height of the drill pipe is reached, the winch is controlled or regulated, taking into account the safety distance and the lifting speed, so that the drill pipe is at the end of the definable or specified distance comes to a standstill.
- the detection of the lifting speed of the drill pipe by means of a speed measuring device can take place directly or indirectly, for example by means of a measuring arrangement that measures the unwinding or winding speed of the traction means or the rotational speed of the winch.
- the lifting speed is preferably recorded at the time the defined height is reached or shortly before/after this in order to use this current speed value as a basis for calculating the braking effect of the drill pipe or the winch.
- a braking distance can be calculated from the measured speed and used as a basis for the control/regulation of the winch.
- the winch when the defined height of the drill pipe is reached, the winch is stopped, with the drill pipe then being continuously raised by the defined or definable distance within the safety distance by manual control of the operator. If required, the operator can therefore use the safety distance according to the invention use the additional height provided to position the drill rods, for example to insert longer support pipes or to open a drill bucket. In other cases, in which it is not necessary to raise the drill pipe beyond the defined height specified by the safety device, the winch stops at the defined height, as in previous systems. Ideally, the operator can further raise the drill pipe any height within the safety distance.
- the winch stops automatically when the winch is manually controlled, i.e. when the manually controlled lifting takes place above the defined height, as soon as the drill rod reaches the end of the definable or specified distance.
- This additional distance can at most correspond to the safety distance, since otherwise a collision with the gallows would occur.
- the operator is not able to manually raise the drill string beyond the safety distance.
- the manually controlled lifting of the drill string above the defined height takes place at a speed which is lower than a maximum lifting speed of the drill string which can be achieved below the defined height. This reduces the braking distance of the drill rod and the safety distance can be optimally used for further lifting.
- the winch is controlled/regulated by means of a controller of the drilling device, which is connected to the safety device and preferably has access to a memory unit in which the value of the safety distance is stored.
- the controller carries out all the calculations required for controlling or regulating the winch and can be connected to an input device, a visualization or output device and/or other actuators of the drilling device.
- the safety device comprises a weight fastened to the gallows in the area of the traction means and a counter-element arranged on the traction means and moved with it, with the counter-element contacting the weight when the defined height of the drill pipe is reached and preferably sending a signal to the control transmitted.
- a limit switch can be arranged on the gallows. On contact, the counter element lifts the limit switch weight, causing the chains to become slack and the limit switch to be actuated.
- the weight can be arranged next to the traction mechanism or can encompass or surround it. Preferably the weight is connected to and depends downwardly from the boom by one or more flexible attachment means such as ropes, wires or chains.
- the weight can be moved or taken along by the counter-element upwards in the direction of the gallows.
- the defined height of the drill string is determined by the height at which the weight is contacted by the mating element (also referred to as the switch point).
- the switching point can also be optical or contactless in some other way.
- a single safety device comprising a weight and a counterweight is provided.
- the winch is ideally regulated above the defined height during continued lifting exclusively on the basis of measured and/or stored values by the control or by manual control of the winch, so that no further weights / switches in the sense of a multi-stage safety device have to be used.
- This enables the safety device to be constructed in a simple and cost-effective manner and is compatible with known rotary drilling machines.
- the weight when the drill string is raised above the defined height, ie from the point in time at which the weight is contacted by the counter element, the weight is lifted together with the drill string.
- the counter-element thus acts as a driver for the weight.
- the traction mechanism is attached to the drill string via a swivel.
- the swivel allows the drill string to be twisted about a vertical axis relative to the traction mechanism or gallows.
- the counter-element is preferably arranged on or in the region of the swivel.
- the safety distance essentially corresponds to the distance between the swivel and the gallows in the area of the traction device. When using a weight and counter element as described above, the safety distance can be defined by the distance between the weight and the boom.
- the drill rod is a Kelly bar.
- the drilling device is preferably a mobile drilling device with a mast or leader, at the upper end of which the boom or Kelly boom is arranged.
- the traction means is in particular a Kelly cable which can be wound up and unwound via a Kelly winch.
- a drilling tool is preferably arranged at the lower end of the Kelly rod, which can comprise a plurality of rods mounted such that they can be slid or telescoped into one another.
- the drilling device is in particular a mobile rotary drilling rig and can include a casing-making machine.
- the present invention further relates to a drilling device as described above, wherein the drilling device has a control or control unit which is set up to carry out the method according to the invention in accordance with one or more of the embodiments described above.
- the controller is set up to receive and process signals from the safety device, a traction element length detection device that may be provided and/or a speed measuring device that may be provided. Furthermore, the controller has access to a memory in particular, in which data such as the safety distance are stored.
- the controller is set up to carry out calculations on the basis of the data transmitted by the various measuring devices and to actuate and control/regulate the winch directly or indirectly on this basis.
- FIG 1 an exemplary embodiment of the drilling device 1 according to the invention is shown in a side view, by means of which the method according to the invention can be carried out.
- the drilling rig 1 is a mobile Kelly rotary drilling rig with a leader 4 mounted on a rotatable superstructure 2.
- the leader 4 has a mast head or Kelly gallows 6 (hereinafter: gallows), over which a Kelly rope is referred to and by means of a Kelly winch 16 up and unwindable traction means 14 is guided.
- a drill rod 10 designed as a Kelly rod is fastened to the Kelly cable 14 and can be raised or lowered essentially vertically along the leader 4 by actuating the Kelly winch 16 .
- a carriage 8 is also slidably mounted on the leader 4 and has a drilling drive for driving the Kelly bar 10 .
- a drilling tool 12 is arranged at the lower end of the Kelly rod 10, which comprises a plurality of rods mounted such that they can be displaced or telescoped into one another.
- the Kelly bar 10 is attached to the Kelly cable via a swivel 18, so that the Kelly bar 10 can be set in a rotational movement about a substantially vertical axis relative to the Kelly cable 14 or to the leader 4 by means of the drilling drive on the carriage 8.
- the Figures 2 and 3 show an enlarged section of the drilling device 1 in the area of the boom 6 in a perspective and a side view.
- the Kelly cable 14 is guided over two deflection pulleys of the gallows 6 and attached to the swivel 18 via a thimble 15.
- the swivel 18 is in turn attached to a so-called Kelly pot 19 at the upper end of the Kelly rod 10 and comprises a plurality of parts which can be rotated in relation to one another.
- a frame 28 through which the Kelly cable 14 is passed and on which a weight 22 is suspended via two fastening means 26 .
- the fasteners 26 can be, for example, chains, ropes, wires, connected rods, or a combination thereof.
- the weight 22 has a cylindrical shape and has a central passage/opening through which the Kelly cable 14 extends, ie the weight 22 encompasses it the Kelly rope 14 and hangs down from the gallows 6 to a certain height.
- a counter-element 24 which is moved along with the Kelly bar 10 and which is set up to interact with the weight 22 and to signal that the Kelly bar 10 has reached a defined height. Counter element 24 and weight 22 together with the limit switch form a safety device 20 to prevent damage to the drill 1 by lifting the Kelly bar 10 too high.
- the counter-element 24 lifts the weight 22 at a certain height, and the limit switch 24 sends a corresponding signal to a controller.
- This situation in which the Kelly bar 10 has reached the defined height (the switching point) and the weight 22 is contacted by the limit switch 24 is in the Figures 4 and 5 shown showing the same cutouts as the Figures 2 and 3 show.
- the height of the weight 22, ie the switching point of the limit switch 24, defines the maximum height up to which the Kelly bar 10 can be raised.
- the limit switch 24 was actuated, the Kelly winch 16 was stopped immediately and the lifting process of the Kelly bar 10 ended.
- the height of the Kelly bar 10 at the switching point of the limit switch 24 is referred to here as the "defined height".
- the height of the limit switch 24, the swivel 18 or the Kelly pot 19 at the switching point can serve as a reference point, but this is not relevant here.
- the weight 22 is suspended at a certain safety distance from the frame 28, which is sufficiently large that even with a maximum braking distance at the maximum Lifting speed of the Kelly bar 10 no collision with the gallows 6 takes place. In known systems, this safety distance could not be used to lift the Kelly bar 10 and represented a kind of "dead path".
- the safety distance is essentially the distance between the weight 22 and the frame 28.
- this safety distance can now be used to raise the Kelly bar 10 further.
- the controller evaluates the measured values of a traction mechanism length detection device, which detects the Kelly cable length currently being unwound, and also takes into account the value of the safety distance stored in a memory.
- the value of the Kelly cable length measurement at the switching point ie when the defined height is reached, is made available to the controller.
- the weight 22 which is freely hanging down and is contacted by the limit switch 24 from below, is lifted upwards in the direction of the frame 28 .
- This situation is in the Figures 6 and 7 shown, in which it can be seen that the flexible fasteners 26 allow such additional lifting and yield to the outside.
- the weight 22 is raised to just below the frame 28 so that the Kelly bar 10 has been raised an additional distance that essentially corresponds to the safety distance.
- the latter can mean that the operator can raise the Kelly bar 10 within a maximum value defined by the safety distance by any additional height above the defined height.
- the additional lifting can always be up to a specified height.
- the Kelly bar 10 is raised above the defined height, taking into account current measurements of the Kelly cable length.
- the maximum possible additional distance is preferably essentially the safety distance in order to have the greatest possible additional height available for lifting.
- the raised weight 22 does not collide with the frame 28 and that a sufficient braking distance for braking the Kelly bar 10 from the lifting movement during continued lifting is taken into account.
- the lifting speed is reduced to a lower speed when the Kelly bar 10 is raised beyond the defined height.
- the controller determines the braking effect that is required so that after the continued lifting of the swivels 18 at the end of the braking distance, ie the lifted weight 22 below the frame 28, comes to a standstill and the Kelly winch 16 above the defined height adjusted accordingly.
- the Kelly winch 16 is automatically regulated in such a way that the Kelly rod 10 comes to a standstill above the defined height at the end of the additional section, which is preferably essentially the safety distance.
- the controller takes into account the length of the Kelly rope that has been unwound and preferably the lifting speed of the Kelly rod 10 at the switching point.
- the controller can control or regulate the Kelly winch 16 and configure the braking process in such a way that the weight 22 comes to a standstill just below the frame 28 (cf. Figures 6 and 7 ).
- a frame 28 does not necessarily have to be provided. It is therefore also conceivable that the weight 22 is suspended directly from the gallows 6 or, for example, is attached to the leader 4, as long as it is ensured that the weight 22 can be moved upwards from the normal position representing the defined height when it is raised further .
- the figure 8 shows the drilling device 1 according to the invention according to FIG figure 1 , the Kelly bar 10 being raised further beyond the defined height, so that the weight 22 is just below the frame 28 . Because the safety distance can now be used according to the invention to further raise the Kelly bar 10, it is possible to increase the X dimension of the drilling device 1 (in Fig figure 8 drawn in as reference character X) to be increased without a mechanical modification of the drilling device having to take place. Furthermore, it is now possible to use a longer Kelly bar and thereby increase the maximum drilling depth.
