Definitions

the invention relates to a device for creating a bore in the ground according to the preamble of claim 1.
a device for creating a bore in the ground according to the preamble of claim 1.
Such a device comprises a carrier device, mounted on the carrier mast, a longitudinally displaceable guided on the mast carriage, on which a drill drive for rotating drives a drill string and a carriage drive for moving the carriage along the mast.
the invention further relates to a method for creating a bore in the ground according to the preamble of claim 1.
the creation of a borehole in the ground can serve different purposes.
the borehole can be filled with a hardenable filling material to create a foundation element in the ground.
the borehole can also be used, for example, to create wells, to explore the ground or in the context of geothermal installations, for example for the introduction of geothermal probes. Also other applications are possible.
the drilling parameters in particular the rotational speed and the propulsion speed, must be selected differently. For example, if the propulsion speed is too low, it is known to increase the rotational speed of the drill pipe and / or to increase the pressure force.
the invention has for its object to provide an apparatus and a method for creating a hole in the ground, which allows a particularly economical creation of a borehole.
the device for creating a bore in the ground is according to the invention characterized in that a control device is provided for controlling the carriage drive and that the control device is adapted to output a control signal to the carriage drive, by which the Auflastkraft of the drill string to the borehole bottom to a predetermined value adjustable is.
a basic idea of the invention is to carry out the control of the carriage drive, that is to say the control of the axial feed of the carriage, based on the value of the loading force of the drill string on the borehole bottom.
the movement of the carriage along the mast is thus dependent on the determined value of the load during the drilling process.
the predetermined value of the load force can be set differently depending on the nature of the ground, for example. For example, in a hard soil material such as rock or rock a higher load or pressure force can be selected as in soft soil, such as soil.
the predetermined value for the supercharging force can be a time-constant value or a time-variable value, for example a vibration.
the setting of a defined load capacity enables a particularly efficient drilling process.
the wear on the drilling tools can be reduced. This leads to longer life and consequently a higher economic efficiency.
an input unit is provided for inputting a target value for the ballast force, in particular by an operator of the device.
the input unit is preferably arranged in a control cabin of the device.
the desired value may be a constant value or a time-variable value.
the device preferably includes a measuring device or a sensor for determining the current value of the load force.
the measuring device or the sensor it is possible for the measuring device or the sensor to be arranged in the area of the drilling tool, that is, at the bottom of the borehole.
a sensor is provided, with which a retraction force and / or pressing force, with which the drill string is withdrawn from the bottom of the borehole or pressed against the borehole bottom, can be determined.
the retraction force and the pressure force are a preferably vertical force with which the drill string is actively raised above the drill drive or pressed against the bottom hole sole. In particular, it is a force with which the drill drive or the carriage is actively pulled or pushed up or down.
the sensor thus determines the force with which the drill string pulls down or pushes upwards on the carriage or drill drive. Based on the determined value of the retraction force and / or pressure force, the ballast can be determined or calculated.
the loading force corresponds to the force caused by the dead weight of the drill string.
the load force can be reduced or increased.
the drill string is raised or retracted. To press it down actively.
the retraction force and / or pressure force can be applied in particular by means of the carriage drive on the Bohrgetriebschlitten.
the adjustment of the current Auflastkraft thus preferably takes place by a force applied to the carriage retraction force and / or pressure force.
the sensor is preferably arranged outside the borehole, in particular in the region of the carriage, the drilling drive and / or the carriage drive.
the sensor is, in particular, a force sensor or force transducer with which the force can be directly or indirectly determined the drill string by its own weight and / or an additionally applied force on the carriage, the drill drive and / or the carriage drive exercises.
a load cell or a pressure transducer can be provided.
the load cell can be arranged in particular at a winch drive of the carriage at the Totseilende.
the pressure sensor can be provided in particular on a cylinder of a cylinder drive.
the load capacity of the drill string on the bottom hole thus depends inter alia on the weight of the drill string.
the control device is set up to determine the dead weight or the gravitational force of the drill string based on the retraction force determined by the sensor.
the drill string can be raised, so that the load is zero.
the retraction force necessary to specify is measured.
the retraction force corresponds to the gravitational force, from which optionally the dead weight can be determined.
a storage device is provided which is adapted to store the determined dead weight of the drill string. Since the dead weight of the drill string during a drilling operation, if the drill string is not changed, remains constant, the weight only once before execution of the Drilling be determined. The self-determined and stored self-weight can then be used during the drilling process to determine or calculate the current load on the bottom of the hole.
the senor is designed to determine the retraction force and / or pressure during a drilling operation.
the force sensor is thus configured to determine the retraction force and / or pressure force continuously or repeatedly during the drilling operation.
control device is designed to determine the load on the bottom hole based on the stored dead weight of the drill string and the withdrawal force and / or pressure force exerted during the drilling operation.
the carriage drive is formed to actively press the drill string to the bottom hole.
the carriage drive is thus designed to actively move the carriage, on which the drill pipe is mounted, downwards, in particular to push or pull.
the carriage drive on a hydraulic feed cylinder.
the hydraulic feed cylinder preferably allows the carriage to be both raised and actively pushed down or pulled.
the carriage drive comprises a cable drive with a winch and a hoist rope.
the rope is preferably guided from the winch over the mast and carries the carriage.
the control device for controlling the carriage drive is preferably designed as a closed loop.
the setpoint is a constant or temporally variable value of the load capacity of the drill string on the bottom of the hole.
the actual value of the load force calculated using the force sensor is returned as feedback and subtracted from the setpoint.
the calculated so Control deviation is fed to a controller which provides an output value or a manipulated variable for the carriage drive.
the control device preferably has a PID controller. This can be designed to perform two to one hundred iteration steps per second. In this way, a precise and fast control can be realized.
the control deviation which is preferably calculated by determining the strand weight and the measured value changed by discharging the strand to the borehole bottom, is fed to a regulator which generates an electrical control signal. This controls, preferably via a proportional valve, the winch or the cylinder of the carriage drive.
the control parameters are preferably set to maximum speed without the system starting to oscillate.
the winch or cylinder pulls up the linkage as soon as there is too much load on the drilling tool and leaves the linkage if there is too little load on the drilling tool. If the linkage or the drill string is too light for the required contact pressure, the linkage is actively pressed downwards.
the hydraulic proportional valve is preferably a valve, which is designed specifically for the winch operation. It contains a load-holding function and a compensation of the load-induced forces on the control piston.
Fig. 1 shows a device 10 according to the invention with a carrier device 12, for example a carrier vehicle to which a mast 20 is preferably pivotally mounted.
a carriage 22 which can also be referred to as a carriage, guided movably.
the carriage drive 40 can basically be designed arbitrarily.
Fig. 2 shows a carriage drive 40 with a winch 46 and a hoist rope 48.
the carriage 22 is suspended from the hoist rope 48.
the hoisting cable 48 is guided, starting from the cable winch 46 arranged on the carrier device 12, over rollers 19 on the mast 20, in particular on a roller head 18 of the mast 20, to a deflection roller 23 on the carriage 22. From the pulley 23, the cable 48 passes to a fixed point on the mast 20 and the roller head 28.
the cable winch 46 controls the length of the unwound hoisting rope 48, the position of the carriage 22.
the hoisting cable 48 in the manner of a Pulley guided.
FIG Fig. 3 Another embodiment of a carriage drive 40 is shown in FIG Fig. 3 shown.
a hydraulic cylinder 42 To move the carriage 22 along the mast 20, a hydraulic cylinder 42 is provided.
the hydraulic cylinder 42 which in principle can be designed as a single-sided or double-acting cylinder, controls the retraction or extension of its piston the position of the carriage 22.
the carriage 22 is connected via two traction cables 44.
the position of the carriage 22 is controlled by means of ropes 44, which are guided over rollers 26 on the mast 20.
the rollers 26 are located at a lower end of the mast 20 and a mast head 21st
the carriage 22 which can also be referred to as Bohrgetriebschlitten, there is a drill drive 24 for rotationally driving a drill string 30.
the drill string 30 can be axially fixed to the drill drive 24, so that a vertical force can be transmitted to the drill string 30 via the drill drive 24, which is also referred to as a power rotary head.
the drill string 30 comprises a drill pipe 32 driven by the drill drive 24, at the lower end of which a drilling tool 34, which may comprise bits and / or drill teeth, is arranged.
Fig. 4 shows the forces acting during the drilling process.
a retraction force or pressing force is transmitted to the drilling tool 34 via the drill pipe 32 and the loading force of the drilling tool 34 is controlled onto the bottom hole 4 of the borehole 2.
the drilling operation is preferably carried out with a constant load or a predetermined time course of the ballast.
a sensor 60 for determining the retraction force and / or pressure force is arranged in the area of the carriage drive 40 or in the region of the suspension or connection of the drill string 30 or drill pipe 32 to the drill drive 24, a sensor 60 for determining the retraction force and / or pressure force is arranged.
the sensor 60 which may be a force sensor in particular, may be used to determine the dead weight of the drill string 30 by measuring the force required to lift the drill string 30.
the measured value of the dead weight of the drill string 30 can be stored in a memory device 70.
a controller 80 For setting a load force with a predetermined value, a controller 80 is provided.
the control device 80 comprises a controller, which receives as input a difference between a set value of the load force and an actual value and generates an output signal which is used to control the carriage drive 40. If the measured load force is too high, an upward retraction force is exerted on the slide 22. If the measured value of the pressing force is too low, a downward pressing force is exerted on the carriage 22.
a particularly efficient drilling process can be realized.
the determination of the dead weight of the drill string 30 before commencement of the drilling process by lifting the drill string 30 from the bottom hole allows an indirect determination of the ballast by measuring the additional retraction force applied to the drill string 30.
