System with an earth drilling device and an input device

Description

[0001] The invention relates to a system comprising an earth drilling device with a control device for operating the earth drilling device, wherein the system further comprises an input device functionally coupled to the control device for entering at least one parameter for the operation of the earth drilling device.

[0002] Earth drilling rigs are typically operated by a user positioned in a control station, usually a cab. The control station contains a seat for the operator, who can control the operation of the earth drilling rig using at least one control element, in particular a multifunction joystick. In addition to the operator, other personnel are usually required on site to monitor and / or carry out the operation and the success of the drilling process.

[0003] DE 20 2017 003 305 U1 discloses a system comprising an earth drilling device with a control device for operating the earth drilling device, wherein the system further comprises an input device functionally coupled to the control device for entering at least one parameter for operating the earth drilling device, wherein the input device is designed as a remote control.

[0004] US 2016 / 0076356 A1 discloses a spaced controller used in the field of oil / gas exploration.

[0005] US 8 272 467 B1 reveals a remote-controlled excavator.

[0006] The object of the invention is therefore to create a system with which the effort required to drill the bore using the earth drilling device can be reduced, in particular the effort in the form of requiring a smaller number of operating and / or monitoring personnel.

[0007] The problem is solved by the subject matter of independent claim 1. Advantageous embodiments are the subject matter of the dependent claims and the description.

[0008] The core idea of ​​the invention is to design an input device, intended for entering at least one parameter for the operation of the earth drilling device, as a remote control. Designing the input device as a remote control allows the operator, previously located in the driver's cab, to choose their location more freely with regard to controlling the earth drilling device. The operator no longer needs to remain in the driver's cab to control the earth drilling device. This freedom of placement allows the operator to be present at other locations while controlling the earth drilling device. This means that, simultaneously, another operator could be present at a location where previously another operator was required to perform or monitor the drilling process.Since the task can now be performed by the operator normally present in the cab, the additional operator is no longer required. This previously necessary additional operator can be assigned other tasks, thus reducing personnel and / or the costs associated with deploying the earth drilling rig. This can result in added benefits for the company using the earth drilling rig.

[0009] The invention creates a system according to claim 1.

[0010] For the purposes of this description, an "earth drilling device" is any device that moves, in particular, a drill string comprising sections within an existing or newly created channel in the ground in order to create or enlarge a borehole, especially a horizontal borehole (HD), or to insert pipelines or other long objects into the ground. The earth drilling device may, in particular, be an HD device. The term "HD" (horizontal drilling) as used in this description includes, in particular, a borehole, channel, or pipeline that is at least partially horizontally arranged. An earth drilling device can thus be a device that drives a drill string, displacing soil and driving the drill string into the ground translationally and / or rotationally in the longitudinal axial direction of the drill string.A borehole can be drilled into the ground by applying tension or pressure to the drill string. The term "drill string" in this context does not exclusively refer to rigid, individual force transmission elements that can be directly or indirectly connected to one another and that may be used in an earth drilling device.

[0011] A front section of the drill string can be designed as a drill head or drilling tool. Furthermore, the drill string, particularly in a front section, can have a probe housing.

[0012] The term "control unit" as used in this description encompasses a control system that enables the directed manipulation of the earth drilling device during operation, i.e., during the execution of or for starting or stopping an earth drilling operation. The control unit can be designed to be either electrical or electronic. The parameters entered by the operator can be used by the control unit—optionally converted and / or processed into electrical signals—as inputs for the operation of the earth drilling device. The earth drilling device can thus be operated or controlled by means of a parameter input, which may have been converted into an electrical signal.

[0013] For the purposes of this description, a "parameter" is understood to be an input that allows for the directed control of the operation of the earth drilling device. The parameter can be transmitted as an input signal to the control unit, which then uses this signal to control the operation of the earth drilling device. For example, a parameter can trigger the start or stop of drilling with the earth drilling device. For instance, an operator can enter the parameter "Start," and a corresponding input signal will be transmitted to the control unit, causing drilling to begin. Similarly, an operator can enter the parameter "Stop," and a corresponding input signal will be transmitted to the control unit, causing drilling to stop.Other parameters that influence or change the operation of the earth drilling device are possible, whereby these parameters can be entered by an operator and converted into an input signal by the input device and transmitted to the control device.

[0014] The term "input device" as used in this description encompasses any electrical or electronic device capable of converting an operator's input into an electrical signal that can be transmitted to the control unit without further processing or with intermediate signal processing, in particular processing in one or more circuits, such as an amplifier, to serve as input or input signal for the control unit. The input device can be understood as the interface between an operator and the control unit. The input device may include a portable power supply, in particular in the form of one or more batteries, accumulators, or similar devices.

[0015] The input device may, in particular, include a processor designed as an arithmetic unit with electronic circuits to execute instructions. The processor can be programmed and is configured to process instructions. The input device may include an operating system that can be modified, for example, to improve and / or adapt to changes in an earth drilling device. Modification of the operating system may only be permitted if a password is used and / or the input device is connected to a computer interface, a dongle, or similar device. Specifically, the processor can recognize, query, process, forward, and / or execute further instructions from a program in the form of parameters from an operator.The processor can execute a program that queries or receives input from an operator, processes the operator's input, sets settings for the operator's input, transmits the input to the control unit and / or receives, processes and / or converts signals from the control unit.

[0016] The term "functionally coupled" as used in this description encompasses a connection, particularly unidirectional or bidirectional, between the aforementioned devices, specifically for the purpose of providing signals from one of the devices, especially the input device, and receiving them with the other device, especially the control device, and / or processing received signals. This functional coupling can be achieved directly or indirectly through the interposition of further elements or devices.

[0017] A "remote control" as defined in this description comprises an electrical or electronic handheld device suitable for controlling the operation of the earth drilling device by entering a parameter from a distance. For the purposes of this description, "from a distance" is to be understood as meaning that direct input via a device attached to the earth drilling device is not necessary. In particular, an operator outside the operator's cab of the earth drilling device can control its operation by entering a parameter.

[0018] In a preferred embodiment, entering the at least one parameter (a) sets a torque and / or rotational speed applied to a drill string of the earth drilling device, (b) sets a linear feed force and / or linear feed rate applied to a drill string, (c) sets a percussion frequency of a percussion piston, (d) sets a percussion amplitude of a percussion piston, (e) sets a flow rate and / or pressurization of a drilling fluid, (f) performs a drill string change, (g) performs drill string lubrication, and / or (h) changes a drill head type. The type of drill string can be taken into account.Particularly with a double-pipe drill string, the torque and / or speed can be selected independently for each inner pipe section, allowing for settings for both the inner and / or outer pipe sections. This enables virtually any input relevant to the drilling operation of the earth auger to be made. In addition to starting or stopping drilling with the earth auger, the aforementioned parameters can be transmitted to the control unit.

[0019] To set the torque / speed applied to the drill string in the direction of the earth drilling operation, the control unit can send a signal to the drive of the earth drilling device, which is connected to the drill string, depending on the parameter entered by the operator via the input device. This allows the operator to set the selected torque / speed. The parameter can be a signal corresponding to the magnitude of the torque / speed. Setting the linear advance of the drill string can involve adjusting the force or pressure and / or speed with which the drive acts on the drill string connected to the drive. Adjusting the linear advance can also include specifying whether the linear advance is a pulling or pushing force, i.e., whether the drill string is pulled or pushed through the soil.Therefore, the term "feed" encompasses both directions, pulling and pushing the drill string, so that a tensile or a compressive force can be applied to the drill string. The parameter can thus be a signal that corresponds to the tensile or compressive force. When drilling into the ground, drilling fluid, particularly in the form of bentonite, can be used. The drilling fluid can be guided through the drill string and exit at the front of the drill string. A flow rate / pressure of the drilling fluid can be set as a parameter, which can be adapted to the conditions in the ground. When drilling with a drill string, it is necessary to extend the drill string during the course of the borehole, in particular by connecting further sections of the drill string to the section already in the ground. For this, an input may be required to perform a drill string change, i.e., to replace the existing section.h. connects another drill string section, particularly from a string magazine, to the already drilled string. This parameter can thus be an action corresponding to the "Change string now" command. During the string change, the drill string already in the ground can be clamped to fix its axial and / or angular position. Furthermore, entering this parameter can involve changing the drill head type, which may be necessary, in particular, if, after drilling a pilot hole (i.e., an initial hole created, for example, by pushing it through the ground), the drill head type is changed to a reaming drill head, which is pulled through the previously created pilot hole to ream it.

[0020] If the earth drilling device is designed as a ram drilling device, the impact frequency and / or impact amplitude of the ram drilling device's impact piston can be adjusted. The term "ram drilling device" or "earth rocket," which is essentially synonymous with the term ram drilling device, encompasses, in the context of this description, a self-propelled impact device that displaces soil and can drive a pipe or conduit into the ground. The term ram drilling device can include earth drilling devices in which the drill bit is longitudinally movable within a housing. The drill bit can be, in particular, a chisel. A ram drilling device can be either a single-stroke or a multi-stroke device. In a single-stroke device, the impact piston strikes the drill bit and, at the same moment, the housing.In a multi-stroke device, particularly a two-stroke device, the impact piston first strikes the drill head tip, which thus moves ahead in the first stroke. The housing is then struck by the impact piston in a subsequent stroke, particularly a second stroke. With a multi-stroke device, tip resistance and shell friction can be separated and thus more easily overcome.

[0021] In a preferred embodiment, the input device has at least one mechanically actuated actuator. The mechanically actuated actuator can be any mechanically or manually operated actuator. A rotary knob, a control stick, and / or a push button are preferred embodiments of a mechanically actuated actuator. Various types of actuators are possible on the input device. Several identical actuators can be provided on the input device.

[0022] A control stick, as described above, is an actuating element for inputting signals, particularly two-dimensional ones. A control stick may have an element extending from a surface, which can generally be tilted in several directions. The element may be, in particular, rod-, stamp-, club-, or lever-shaped. The element may extend from a surface to a height not exceeding 7 cm, preferably 6 cm, preferably 5 cm, preferably 4 cm, preferably 3 cm, preferably 2 cm, or preferably 1 cm. The diameter of the element may, in particular, be less than 5 cm, preferably 4 cm, preferably 3 cm, or preferably 2 cm. A control stick, as described above, may also be called an analog stick or joystick and may be functionally equivalent to these. The term "control stick" also includes a directional pad with which the input of two-dimensional signals is possible.The control stick can generate a signal that depends on the position of the element or directional pad relative to a standard or resting position. It can be configured to provide single electrical signals when actuated and / or a continuous electrical signal in the form of voltages and / or currents, using one potentiometer for each of the dimensions in which the element or directional pad can be tilted; for example, one potentiometer for the up / down position and one for the left / right position. Changing the position or orientation of the control stick's element or directional pad relative to its resting or standard position can change the voltage.The size and / or arrangement of the control stick on the input device can be designed such that it can be operated by a person's thumb and / or finger; in particular, it is possible to operate the control stick without gripping it. If the control stick is designed to generate signals depending on movement in at least two dimensions, this also includes the possibility of providing an input for controlling the operation of the earth drilling device by means of a control stick, in which the control stick does not generate any signals regarding movement in one of the dimensions and / or signals regarding movement in one of the dimensions are not considered or need not be considered by the control device.

[0023] A rotary control or knob as described may incorporate a potentiometer or be formed by one. Advantages of these rotary controls are that they are essentially maintenance-free and insensitive to vibrations; furthermore, turning the rotary control when it is switched off may have no effect.

[0024] A push button, as described, is an actuating element that can be designed as an assembly and establishes or breaks an electrically conductive connection. The push button can be designed as a toggle switch or a simple push button. It has been found that an actuation stroke of at least 2 mm is advantageous for a push button to be considered a "deliberate" actuation. Actuation strokes of more than 2.3 mm are preferred, and with gloves, actuation strokes of more than 3 mm, preferably more than 5 mm, particularly preferably more than 6 mm, and even more preferably more than 7 mm, may be provided. Regarding the diameter of a push button, it has proven advantageous for it to be more than 5 mm, particularly more than 7 mm, to allow actuation by a user's finger.When operated by the thumb of an operator, the diameter of a push button can advantageously be more than 15 mm, preferably more than 17.5 mm, and in particular more than 20 mm.

[0025] A selection of mechanically actuated control elements can be provided on the input device. In particular, control elements commonly used in the prior art can be employed to allow the operator the usual input method for controlling the earth drilling device. The size and / or arrangement of the control elements may vary compared to the prior art; in particular, a control stick on the input device may be smaller than a multifunction joystick located in the operator's cab.

[0026] In a preferred embodiment, at least one mechanically actuated actuator, in particular a control stick, is arranged as an interchangeable unit in a receiving space of the input device. This allows for the quick replacement of an actuator required for operating the earth drilling device, thus enabling the operator to operate the device as continuously as possible. Such a simple replacement can be advantageous because the input device is operated from outside the driver's cab, as the actuator may be subject to greater wear.

[0027] In a particularly preferred embodiment, a capacitive or mechanically actuated actuator and / or a radio transmitter can be provided on the input device, in particular to determine whether the operator responsible for operating the earth drilling device is holding or grasping the input device. In this respect, an actuator and / or a radio transmitter can be provided to determine whether an operator can operate the input device or is in its immediate vicinity. A capacitive or mechanically actuated actuator can detect the presence of the operator just as a radio transmitter can. For example, with a mechanically actuated actuator, it can be determined whether the operator is actuating the respective actuator to allow input and / or further operation of the earth drilling device and not to put it into a protected state.For example, it can be stipulated that a parameter input only occurs if the respective actuator has positively detected that the operator is holding or grasping the input device, or simultaneously operating the actuator. This allows it to be determined, for instance, whether the operator has put the input device aside to perform work on or access the earth drilling rig, while the rig is still drilling and driving the drill string. In such a case, the earth drilling rig can be shut down or put into a standby state. The input device can then transmit a signal to the control unit corresponding to a parameter, which in a practical instruction could mean "force standby" or "emergency shutdown."It may be provided that the "standby state" of the earth drilling device differs from the state of the earth drilling device after an "emergency shutdown"; in an "emergency shutdown" the earth drilling device may be switched off, whereas in a "standby state" the units and / or drives of the earth drilling device remain switched on but without drive.

[0028] In a preferred embodiment, the sensitivity of the mechanically actuated control element is adjustable (a) mechanically and / or (b) by means of software that is functionally coupled to the control element via a sensor and a counter element. This allows an operator to adjust the sensitivity, particularly of a control stick or rotary dial, even under different conditions, for example, with or without gloves. For instance, two different sensitivity settings for a control element are possible: 1) operation with gloves or 2) operation without gloves. It can also be provided that the sensitivity can be adjusted depending on the type of input or parameter. The adjustment can be made by the processor in the input device.

[0029] In a preferred embodiment, the input device has at least one, and in particular two, mechanically actuated operating elements, especially one or two pushbuttons, which are spaced at least so far apart from each other on the input device that two-handed operation is required. This creates a so-called dead man's switch, which can be used to check whether an operator is present or able to act. If it is detected that one of the operating elements is not being actuated, it can be concluded that the operator is not present and / or unable to act, which can trigger a signal or a switching action. This allows for an increased level of safety during the operation of the earth drilling device. For example, an operator can be prompted by means of a haptic signal, a visual display, and / or an acoustic signal to stop the operation.The two operating elements must be actuated; if no actuation occurs, a signal or switching action can be triggered, which puts the earth drilling device into a standby state or shuts it down (in an emergency). Providing two mechanically actuated operating elements, only one of which needs to be used as a so-called deadman's device, can offer the advantage that—provided the mechanically actuated operating elements are located on both the right and left sides of the input device—the input device can be operated ergonomically and easily by both right- and left-handed operators. It may therefore be sufficient to have a deadman's device on either the left or right side. However, providing both options on the right and left sides takes into account the potential requirements of the operator.

[0030] In a particularly preferred embodiment, a monitoring device, which can be integrated as part of the processor, is provided. The monitoring device is configured to check the simultaneous actuation of two actuators. Additionally or alternatively, it can be provided that the device also monitors whether the simultaneously actuated actuators are not actuated again within a predetermined time window. With the aid of the monitoring device, a time difference with regard to the "simultaneity" of the actuation of the two actuators can be set as a tolerance. It can also be optionally set after which the actuators must be released again. A simple design of a deadman's device is possible.

[0031] The input device can have a circumferential outer contour, in particular interrupted or closed, which can enclose an inner contour or interior of the input device. The circumferential outer contour can be essentially rectangular, square, polygonal, round, circular, and / or elliptical over the entire area or only in sections. Mixed forms and combinations of the aforementioned shapes are possible. In particular, the input device can be essentially rectangular or cuboidal and have dimensions ranging from 15 cm to 50 cm in width, preferably 20 cm to 40 cm in width, 10 cm to 30 cm in length, preferably 15 cm to 25 cm in length, and 3 cm to 15 cm in height, preferably 5 cm to 10 cm in height.

[0032] The input device may have at least one projection or several projections, particularly two, especially with respect to one of the aforementioned shapes, which may be designed for grasping by the operator's hands. In particular, the projection(s) may be designed as a handle. A handle-like design that can be enclosed by the operator's hand is preferred. The projection(s) may project beyond the rectangular, square, polygonal, round, circular, and / or elliptical shape of the input device. The mechanically actuated actuating elements may be formed on one or each of the projections. The projections may be designed on the input device such that a surface facing the operator is formed by means of the projection or projection.the projections result in a surface that may lie in a plane. It may be provided that the projections protrude from a surface with the aforementioned shape, in order to form, in particular, a receptacle, especially having the outer circumferential contour, for a display device described below, either completely or partially. The projection(s) may project from a base surface or base plate. The projection(s) may form, at least partially, an edge on a base plate that has the aforementioned shape. The projection(s) may be offset forward from the base plate. If several projections are present, the projections may protrude from a base surface or base plate in the same direction and form an edge on it. The base plate with the projection orThe projections can, in particular, partially replicate the outer circumferential contour of a display device. The base plate can be completely closed or have openings. A wall can project from the edge of the base plate, at least partially or completely, which can surround a display device described below, at least partially or completely.

[0033] A curved adaptation of the protrusions to the shape of the operator's hands is possible, particularly at the corners of a protrusion. The respective protrusion can be adapted to the dimensions of an operator's hand; this allows the input device to be designed independently of the operator's hand dimensions in other areas. It is possible that adaptation to the dimensions and shape of the hands is limited to the protrusions. An adaptation to the shape and / or dimensions of the operator's hands, which may result in a reduction of the overall design, can thus be limited to the protrusions alone.

[0034] The aforementioned projection(s) can have a diameter of 3 cm to 5 cm, preferably 3 cm to 4 cm, to allow for a good grip by an operator's hand. The length of a projection can be greater than 10 cm, preferably greater than 15 cm, to allow for a good, and in particular fatigue-free, grip by an operator's hand, for example, to also take into account that the operator is wearing a glove.

[0035] If more than one projection is formed on the input device, the projections can be located on opposite sides of the input device. A mirror-symmetrical arrangement of the projections is possible. The mechanically actuated actuators can be mirror-symmetrical to each other when multiple projections are provided.

[0036] When the operator grasps the respective protrusion with their designated hand, a control stick can be arranged on the protrusion in the thumb area. Preferably, a control stick is arranged on each protrusion in the thumb area. Preferably, a mechanically actuated actuating element designed as a control stick rises from a substantially flat or non-curved surface. The control stick can rise from a surface of the input device facing the operator. In particular, a control stick can rise from a surface parallel to the base of the input device, which can be substantially defined by its outer circumferential contour.

[0037] If a control stick is provided on the input device, a further mechanically actuated actuator, in particular a rotary control, can be arranged on a surface of the projection that differs from the surface for the control stick. Regardless of whether a control stick is provided, a rotary control can be arranged, in particular, on a surface of the projection that extends away from the operator. The surface on which a rotary control is arranged can, in particular, form an angle of 10° to 60°, preferably 20° to 50°, with a surface that faces the operator when holding the input device or on which a control stick is provided.The rotary control can be arranged in such a way that it can be easily operated by the index or middle finger of the operator while holding the input device, especially if the operator grasps the protrusion on the input device, if provided.

[0038] If a control stick is provided on the input device, a push button may be arranged on a separate surface designated for the control stick. A push button may be arranged, in particular, on a surface of the projection that extends away from the operator when holding the input device. If a control stick is provided, the surface on which the push button may be located may be opposite the surface from which the control stick rises. The surface on which a push button is arranged may, in particular, form an angle of 10° to 60°, preferably 20° to 50°, with a surface on which a control stick is provided.The push button can be arranged in such a way that it can be easily operated by the index finger, middle finger or ring finger of an operator when the operator is holding the input device, in particular when the operator grasps the protrusion that may be provided.

[0039] It may be provided that a push button and a rotary switch can be located on the same surface at a distance from each other, whereby operation with different fingers of an operator is particularly possible.

[0040] A projection of the input device can have essentially three surfaces, each with at least one mechanically actuated actuator. The surfaces with a mechanically actuated actuator can form an angle with each other. The surfaces can be curved. A mechanically actuated actuator designed as a rotary actuator can preferably be arranged on a curved surface, the curvature of which can substantially correspond to the curvature of the rotary actuator, so that, in particular, the rotary actuator can be actuated over an angular range greater than 180°, greater than 190°, greater than 200°, greater than 210°, greater than 220°, greater than 230°, greater than 240°, greater than 250°, greater than 260°, greater than 270°, greater than 280°, greater than 290°, and greater than 300°.This means that a rotary control can easily be operated by an operator who can wear gloves.

[0041] A mechanically actuated element designed as a push button can preferably be arranged on a curved surface. The push button can have a curvature that substantially corresponds to the curvature of the surface. It can be provided that the push button can be actuated over a larger angular range, which may correspond to the angular range of the curvature. Actuation can also occur if the push button is not actuated in a straight line.

[0042] A structuring of the input device for the at least partial or complete inclusion of another device, in particular a display device described below, is possible, whereby inclusion in the sense of the description refers to a possibility of a connection between the two devices, in particular the input device and the display device, which may in particular be positive locking and / or force locking.

[0043] In a preferred embodiment, the input device has a surface, not necessarily flat, on which at least two actuating elements are arranged in the area of ​​two adjacent corners and / or opposite edges. The corners and / or edges can also be formed on one or more projections. This allows for an ergonomically favorable arrangement of the two actuating elements for the operator. The principles of optimal adaptation can thus be met. Occupational health, user-friendliness, ergonomic, or ergonomic design considerations can be taken into account for the operator.

[0044] In a particularly preferred embodiment, the input device can be gripped by an operator's hand in the area of ​​the corners and / or edges – optionally in the area of ​​a projection. Furthermore, in the preferred embodiment, at least one actuating element can be arranged in the area of ​​the corners and / or edges – optionally on one or more projections – such that it is reachable by a finger or the thumb of the user when gripping the corners and / or edges. It has been found that this achieves optimal adaptation from an ergonomic perspective, taking into account occupational health, ergonomics, and user-friendliness criteria. For example, the thickness of the input device's corners and / or edges can be adapted to the hand of an operator, taking into account whether the operator is wearing gloves or not.

[0045] In particular, the actuating elements located in the corners and / or edges may be control sticks. Specifically, the control sticks may be arranged on a surface of the input device that forms a base or is arranged parallel to and offset from it.

[0046] In a preferred embodiment, the input device is configured as (a) a wired and / or (b) a wireless remote control. In a particularly preferred embodiment, the input device is a wireless remote control, which allows the operator to move around essentially freely with the input device without having to pay attention to a cable connecting the input device to the earth drilling device. A wired remote control offers the advantage of essentially undisturbed signal transmission via the cable.

[0047] In a preferred embodiment, the input device is configured to use one or more radio bands for communication with the control unit of the earth drilling device. For the purposes of this description, a frequency band refers to frequency ranges, i.e., sub-ranges of the electromagnetic spectrum of the electromagnetic waves used for technical communication. Classifications based on frequency, wavelength, or application are common. Various designations for the frequency bands, particularly international ones, are possible.

[0048] In a preferred embodiment, the input device has one or more antennas to provide signal paths, particularly in one direction, for example to increase safety during the operation of the earth drilling device. It may be provided that bidirectional signal transmission between the input device and the control device is possible by means of one antenna. Alternatively, it may be provided that at least one antenna is provided for each direction (from the input device to the control device and from the control device to the input device), and that different antennas are used for the two directions. The antenna(s) may be connected to the processor of the input device.

[0049] Bidirectional communication between the input device and the control device is possible. For example, the control device can confirm the input of a parameter or transmit to the input device that an error occurred during input and / or transmission to the control device.

[0050] In a preferred embodiment, the earth drilling device has one, two, or more antennas for communication with the input device. The earth drilling device can, by means of the control device, in particular use the signal that is strongest, best, or most stable.

[0051] In a preferred embodiment, the input device has a status indicator for displaying a state. The status indicator can be connected to the processor. The status indicator can display a state regarding the power supply of the input device, the transmission of data and / or signals from the input device to the control device, the signal strength, an indication that the input device is switched on or off, and / or an error message. The status indicator can be reduced to essential information, so that, for example, a display only occurs when a specific—for example, critical—state is reached. For instance, the status indicator can be configured to detect a reduced power supply or an imminent depletion of the input device's power supply.Alternatively or additionally, the status indicator may show that an error has occurred during data transmission from the input device to the control unit. Alternatively or additionally, the status indicator may show that the signals generated by an actuating element are faulty. Alternatively or additionally, the status indicator may show that a fault has been detected in the earth drilling device or the control unit, particularly in the form of a signal from a device monitoring a critical condition. The status indicator may be a plain text display, a simple light source, particularly an LED, which may be colored. In the case of a simple light source, the color of the light source may correspond to the status to be displayed to the operator. For example, the color may change, or a differently colored light source may be activated.The indicator light illuminates when the type of condition or the condition itself changes. For example, a green indicator light may be used when the earth drilling device is in operation and no fault has been detected. If the condition deteriorates, for example, if the power supply capacity has decreased below a certain level, the color orange may be used. A further reduction or a fault may be signaled with the color red. A symbol may be placed or displayed within or as part of the status indicator, particularly in the form of a printed symbol, to indicate the specific information the status indicator relates to. For example, a battery or accumulator symbol may be used for a power supply status indicator. An antenna symbol may be used for a transmission error status indicator.

[0052] In a preferred embodiment, at least one protective projection is provided for at least one mechanically actuated actuator, wherein the extent of the protective projection transversely to the surface on which the actuator is arranged is equal to or greater than the extent of the actuator transversely to the surface. For example, a protective projection can have an extent equal to or greater than that of a control stick. This prevents unintentional actuation of the actuator, and a relatively simple mechanical design may suffice. The protective projection can, for example, prevent an input device falling to the ground from coming into contact with the ground in such a way that the action of the ground surface causes the actuator to be actuated.In addition to the aforementioned spatial extent, the protective ridge can be arranged relative to the mechanically actuated actuator in such a way as to largely prevent unintentional actuation. It may be preferred that the protective ridge be arranged in close proximity to the mechanically actuated actuator. The protective ridge can extend around the mechanically actuated actuator in several directions. The protective ridge can be located between an outer edge of the input device and the mechanically actuated actuator. The protective ridge can form a wall, at least partially interrupted or continuous, between the edge of the input device and the mechanically actuated actuator. The wall can extend in two directions with respect to two different edges of the input device.It is also possible to have more than two walls that can at least partially surround or enclose the mechanically actuated operating element, provided that mechanical access by the operator is still possible.

[0053] In a preferred embodiment, the input device has a mechanically rigid structure adapted to the portion of a human operator's body, in particular a finger. This allows for the creation of an input device adapted to occupational health, user-friendliness, and / or ergonomic criteria, which in particular enables fatigue-free operation without hand strain.

[0054] In a preferred embodiment, the input device has an attachment point for a carrying strap worn by the operator, thus relieving the operator of the burden of holding the device's weight. This allows for less tiring and more comfortable operation. Alternatively, the attachment point can be used to carry the input device. The operator can release the device, and it will still remain attached to the operator, for example, by a carrying strap designed as a shoulder, neck, or waist belt.

[0055] The input device comprises one element of a connection pair that can interact mechanically and / or electrically with another element of the connection pair, which is arranged or formed on the earth drilling device. The connection pair can consist of a pair of elements for forming a mechanical and / or electrical connection. The input device can be securely held on the earth drilling device by means of the mechanical connection. An electrical connection can, for example, enable signal transmission and / or power transmission. Charging a battery or powering the input device is possible. The other element of the connection pair can be located, in particular, in the operator's cab on the earth drilling device.By means of the additional element of the connection pair in the driver's cab, it is possible to use the input device at a fixed location on the earth drilling device that is familiar to the operator and where the operator is essentially protected from environmental influences.

[0056] In a preferred embodiment, the earth drilling device has a control stick that is larger than the control stick on the input device. This allows the operator to retain the familiar input method using a multifunction joystick via the control stick. In particular, the operator can find a control stick—larger than the one on the input device—in the driver's cab. The earth drilling device can be operated in the driver's cab in the usual manner.

[0057] In a preferred embodiment, a display device is provided for showing at least one parameter for the operation of the earth drilling device. The display device is designed such that it can optionally be mechanically connected to the input device and / or mechanically connected to a coupling on the earth drilling device. This allows, on the one hand, the display device and the input device to form a single, easily handled unit that can be held by one operator. On the other hand, it allows the display device to be connected to the earth drilling device, and the input device to be connected to the display device, thus indirectly mechanically connecting the input device to the earth drilling device. The operation of the earth drilling device can be visualized by means of the display device.The display device can be, in particular, an electrical or electronic display, specifically a liquid crystal display (LCD), light-emitting diode (LED) matrix display, luminescent display (VFD), or similar. The display device can, in particular, provide an image display that is especially intuitive to understand. It can be a universal display instrument such as a screen, monitor, display, tablet, notepad, iPad, smartphone, or smart display. In addition to the input device, the display device thus enables the operator to visualize the operation of the earth drilling device with regard to at least one parameter, and this visualization can be carried on-site.

[0058] In a preferred embodiment, all the aforementioned parameters for operating the earth drilling device can be accessed and / or displayed using the display device. The display can be configured so that not all parameters are shown simultaneously, but rather one or more parameters are displayed depending on the operator's input. The operator can select these parameters for display, or they can be selected by a sequence of commands from the control unit for executing and / or entering a parameter. Thus, the display device can be coupled with the input device in such a way that when the operator wants to enter a parameter using the input device, parameters, data, information, and / or instructions related to that parameter are displayed on the display device.The coupling can be achieved through direct communication between the display device and the input device, or through indirect communication between the display device and the input device, for example via the control device.

[0059] In a preferred embodiment, the input device has an inner contour adapted to the outer contour of the display device, wherein the input device at least partially surrounds the display device along a section of the outer contour of the display device. In this way, a connection can be established between the input device and the display device, in which the display device is at least partially surrounded by the input device. The display device can be located within the input device, the term "within" also encompassing the case where the input device does not completely enclose the display device. A substantially central arrangement of the input device around the display device is possible. In particular, the input device can contact the display device on one, two, three, or four sides.A positive fit and / or a friction fit can be formed between the display device and the input device. In particular, the positive fit – as well as the friction fit – can be selectively released to separate the mechanical connection.

[0060] In a preferred embodiment, the display device is a tablet, iPad, notepad, or similar device, which allows for a particularly simple design. The display device can utilize a display element that is essentially known from the prior art. The aforementioned display options are known, and their use is familiar to an operator. The aforementioned design options for the display device enable intuitive operation.

[0061] In a preferred embodiment, the display device includes a control unit designed for context-sensitive information display. For example, the control unit can display the value of a parameter for the operation of the earth drilling device, information related to the parameter, and / or setting instructions when relevant to the operator and / or when the operator wishes to enter or change such a parameter. For instance, if the operator enters a parameter using the input device, the control unit can display the parameter being influenced or changed by the operator, even during the change or entry process. It is possible, for example, to continuously decrease or increase a parameter using the input device, with its value displayed on the display device.It is also possible for the control device to communicate with the control unit to display information, parameter values, instructions, and / or error messages. For example, the control device of the earth drilling rig can inform the control unit of the display device when a drill string needs to be connected to the drilled drill string to continue drilling. Furthermore, it can display states of the earth drilling rig that require operator action.

[0062] In a preferred embodiment, the display device and the input device are functionally connected such that when an input is made at the input device, the input is displayed by means of the display device. The input device can transmit a signal to the display device directly or indirectly via the control device of the earth drilling device, indicating which parameter is to be changed or entered by the earth drilling device, so that the display device shows the current value of the parameter and / or parameters related to the parameter.

[0063] In a preferred embodiment, the display device has an input area adjacent to the input device when the two are connected. This allows the operator to make additional inputs to the display device, in addition to the input provided by the input device. This input can, in particular, modify the information displayed on the display device, specifically changing the display format. It also allows for the retrieval of information related to the earth drilling device. Furthermore, the input area on the display device provides a clear separation between the different inputs the operator can make.The input controls for changing, for example, the information to be displayed, do not need to be provided on the input device; the input device can be limited to entering the parameters necessary for operating the earth drilling device. Input via the display device can be achieved using a touch-sensitive display known from the prior art. Preferably, at least one mechanically actuated actuator is located adjacent to the display device.

[0064] The display device can allow the input of parameters, functions, and / or changes to the display itself. If the display device has a touchscreen, this input can be made by touching, tapping, swiping, or similar means. Alternatively or additionally, input can also be made to the display device using an integrated device or an additional connectable device (for example, via a wired connection and / or wirelessly, such as via Bluetooth).The integrated or additional device may be a mechanically actuated operating element (for example, a push button, a rocker switch), a keyboard, a mouse, a trackball, a graphics tablet, a microphone, a camera or a similar input device, in particular in the form of a peripheral device otherwise known in the computer field, with which key or writing inputs, audio inputs (speech input) and / or video inputs (gestures, movement or the like) are possible.

[0065] In a preferred embodiment, the display device is connected (a) wirelessly or (b) via cable to the control unit of the earth drilling device. This allows for a certain degree of mobility of the display device. In the case of a wireless connection, the mobility of the display device is increased with regard to the operator's freedom of movement.

[0066] In a preferred embodiment, the display unit is designed for wireless data exchange via WLAN. This allows the use of a data protocol or transfer protocol that is known and easy to manage. In particular, the data exchange or functional coupling between the display unit and the control unit of the earth drilling device can be separate from the data exchange or functional coupling between the input unit and the control unit of the earth drilling device. For example, a lower level of communication security can be selected for the data exchange between the display unit and the control unit of the earth drilling device.

[0067] In a preferred embodiment, one or more antennas are attached to the earth drilling device for communication with the display unit. The use of two antennas, in particular, on the earth drilling device allows the control unit of the earth drilling device to use the signal that is the best, most stable, or strongest at each antenna. Using multiple antennas minimizes or even eliminates interference. In a preferred embodiment, an antenna, particularly an integrated one, can be located on the display unit. To increase the range, an additional antenna can be screwed onto the display unit in a preferred embodiment. Increasing the range is particularly advantageous when the operator is located a considerable distance from the earth drilling device along the drilling path.It may also be provided that several antennas are provided on the display device, from which the best, most stable or strongest signal is taken.

[0068] In a preferred embodiment, the input device and the display device have separate power supplies. This allows for greater flexibility. The power supply for each device can be smaller than a single power supply for both the input device and the display device. Furthermore, the power supply of a standard display device can be used.

[0069] In a preferred embodiment, the display unit includes communication means for transmitting data and / or signals between the display unit and a positioning system for the drill head. This allows the display unit to show not only the parameters or information for operating the earth drilling device, but also the location of the drill head in three-dimensional space as determined by the positioning system. The control unit can thus be configured to process and utilize the signals from a positioning system to display the current or determined location of the drill head. This display can be implemented in various ways. A graphical representation on a map, which can be three-dimensional or two-dimensional, is possible.It may be designed so that the tracking system does not transmit the data directly to the display unit, but instead transmits the data to a gateway. This gateway collects all data—not only the tracking data, but also the operational and drilling data that are recorded. The gateway can then, in turn, send the tracking data and any other collected data to a cloud. From there, it can be retrieved, analyzed, and transmitted. The display unit is designed for data analysis. If it is described that the display unit has communication means for transmitting data and / or signals between the display unit and a tracking system, this also means that the display unit can retrieve and / or analyze this data, for example, by retrieving it from the cloud.Alternatively or additionally, it is possible for the location data to be sent and used directly from the gateway - without the intermediary of a cloud - or directly from the location system to the display device.

[0070] In a preferred embodiment, the display device has a data output, which is intended in particular for outputting a log of the operation of the earth drilling device, especially a log of the drill head's location as recorded by the tracking system at predetermined intervals or continuously. This allows an automatically generated log to be output at the data output, which can be archived for billing purposes, documentation of the drilling, or similar purposes. The data output can also be used for other purposes.

[0071] In a preferred embodiment, a detection device is provided which is configured to detect the end of the drill string (a) in the area of ​​the earth drilling device and / or (b) in the area of ​​a target pit of an earth borehole to be constructed, wherein the detection device has transmission means which are configured to transmit signals to the display device and / or the control device, wherein the display device and / or the control device are configured to process the signals from the detection device in such a way that the signals are displayed for a user on the display device. This allows an area to be detected in which an (additional) operator is typically present to monitor the operation of the earth drilling device.By recording and displaying the data on the display unit, the operator controlling the earth drilling rig via the input device receives the relevant information. This allows the operator to see the corresponding end section of the drill string with respect to the data being recorded, regardless of their position. It may be possible to design the system so that the operator is not physically present at the end section of the drill string. The signal from the recording device can be used. This offers a further advantage, as it may eliminate the need for a second operator to perform the drilling and allow them to be assigned other tasks.

[0072] For the purposes of this description, a "detection device" encompasses any device designed to detect the presence of a drill string, in particular the end of a drill string, a drill section, or a drill head, within a given area. The detection device may be designed to identify changes in the presence of the end of a drill string, a drill section, or the drill head.

[0073] In a preferred embodiment, the detection device is a camera, an area scanner and / or a motion scanner, whereby known devices whose handling and use - albeit for other areas - are common can be used.

[0074] For the purposes of this description, a camera is any device that captures an image of an area, which can then be displayed, in particular, on the display device. The display device can show the signals or information from the camera, at least on a portion of the display. The signals can be displayed directly or processed by the control unit of the display device and / or the control unit of the earth drilling device before being displayed.

[0075] For the purposes of this description, an area scanner is a device that can detect or record changes in the presence of an object within a defined area. The area scanner can be designed as a light barrier, light curtain, or similar device. It can also utilize ultrasound, electromagnetic radiation in the infrared range, or radar waves.

[0076] For the purposes of this description, a motion scanner is a device that can detect or record movement in an area.

[0077] Both the area scanner and the motion scanner can be used such that, whenever movement of any kind is detected, a message is sent to the display unit. It can also be provided that a signal from an area scanner or motion scanner is transmitted to the input unit, and that a response from the area scanner and / or the motion scanner is indicated on a status display of the input unit. It can also be provided that, as soon as the area scanner and / or the motion scanner is triggered, an image from a camera is displayed on the display unit, so that the display of an image from any camera that may be present only occurs once the area scanner and / or motion scanner has detected a change in or the presence of the end of a drill string or drill bit, or the drill head.

[0078] A method for controlling the operation of an earth drilling rig is described. The method includes the step of entering at least one parameter for the operation of the earth drilling rig. This parameter can, in particular, be a parameter that causes drilling to start or stop. The input of this at least one parameter is performed using a remote control.

[0079] This document describes the use of an earth drilling device that includes a control unit for operating the device. An input device, functionally coupled to the control unit, is used to input at least one parameter for operating the earth drilling device. This parameter can, in particular, be a parameter that starts drilling with the earth drilling device or stops drilling already underway. A remote control is used as the input device.

[0080] Three aspects are described, relating to a system, a process, and a use. The descriptions of each aspect complement each other, so that the description of the system can also be understood as descriptions of the process and the use. The description of the system also discloses actions related to the process or process steps, as well as uses or usage characteristics, which apply to the corresponding aspects.

[0081] For the purposes of this description, the mention of a numerical value, in particular a length or angle specification, includes not only the actual numerical value, but also – in order to take into account manufacturing tolerances in particular – a range around the specific numerical value, which may be + / - 15%, preferably + / - 10%, of the specified numerical value.

[0082] The foregoing statements, as well as the following description of exemplary embodiments, do not constitute a waiver of certain embodiments or features.

[0083] The invention is explained in more detail below by way of example using an embodiment shown in the figures.

[0084] The drawings show: Fig. 1 a schematic representation of an earth drilling device with an input device; Fig. 2 a schematic representation of the input device and the display device; Fig. 3 Another representation of the input device with the display device from above; Fig. 4 the input device with the display device from below; Fig. 5 a representation of the input device with the display device in operation; Fia. 6 a further illustration of the input device and the display device in operation; Fig. 7 a further illustration of the input device with the display device in operation; and Fia. 8 a schematic representation of an embodiment in which the end area of ​​the drill string is monitored in the area of ​​the earth drilling device and a target pit.

[0085] Fig. 1 Figure 1 shows a schematic representation of an earth drilling device 1, with which a borehole can be drilled into the ground. A rod magazine 2 stores rod sections with which the drill rod 3, which has already been driven into the ground, can be extended.

[0086] The earth drilling device 1 has a control unit 4 for operating the earth drilling device 1, which is schematically visualized by means of the dashed box. The operation of the earth drilling device 1 can be controlled by means of the control unit 4.

[0087] Furthermore, an input device 5, functionally coupled to the control unit 4, is provided and is designed for inputting at least one parameter for the operation of the earth drilling device 1. In particular, such a parameter can cause drilling with the earth drilling device 1 to start or to stop drilling already carried out with the earth drilling device 1. The input device 5 is designed as a remote control, which communicates wirelessly with the control unit 4 by means of electromagnetic waves.

[0088] The wireless communication between the input device 5 and the control device 4 is bidirectional, in which the input device 5 both receives signals from the control device 4 and sends signals to the control device 4. This bidirectional wireless communication is visualized by the double arrow ES.

[0089] Furthermore, a display unit 6 is provided, which can display information and / or parameters for the operation of the earth drilling device 1. For the purpose of displaying the information and parameters, the display unit 6 is functionally coupled to the control unit 4. Communication between the display unit 6 and the control unit 4 is wireless via electromagnetic waves. The communication is bidirectional, so that the display unit 6 can both receive signals from the control unit 4 and send signals to the control unit 4. The bidirectional communication is visualized by means of a double arrow AS.

[0090] As among others, the Fig. 2 As can be seen, the display device 6 can be arranged in a receptacle 7 of the input device 5 in such a way that the display device 6 together with the input device 5 can be handled as a unit by one operator.

[0091] The input device 5 has several mechanically actuated operating elements 8, two of which are designed as control sticks. Furthermore, the input device 5 has an emergency stop switch 9 as a mechanically actuated operating element 8, which is designed as a push button. The operating elements 8 designed as control sticks and the emergency stop switch 9 face the operator when the input device 5 is held and are located in the same plane of the input device 5. Opposite the surface on which the control sticks and the emergency stop switch 9 are arranged, two rotary controls are provided as mechanically actuated operating elements 8 to the left and right of the input device 5.

[0092] The input device 5 has several status indicators 10 on the left side, which provide information about the status of the input device 5, the earth drilling device 1 and / or communication between the input device 5 and the control device 4.

[0093] Furthermore, the input device 5 has a receiving compartment 11 on the underside of the input device 5, designed as a receiving compartment for the arrangement of a power supply for the input device 5.

[0094] A swiveling antenna 12 is provided for wireless communication with the control unit 4, which can be swivelled with respect to its orientation and can be changed telescopically in length.

[0095] A protective ridge 18 is provided on the input device 5 to protect the actuation of the mechanically actuated actuating elements 8, which is located in the area of ​​the emergency stop switch 9 and the control sticks.

[0096] Connecting elements 13 are provided for attaching a neck, shoulder or hip strap, with which the corresponding strap can be connected.

[0097] The input device 5 has a base plate 14 for receiving the display device 6, which is essentially rectangular in shape (see figure). Fig. 1 The mechanically actuated operating elements 8 are formed on grip-like projections 15 of the base plate 14, each of which can be grasped by an operator's hand to perform the actuation. The projections 15 extend upwards in one direction and form a rim around the base plate 14. Each projection 15 forms a rim on one side. The two rims formed by the projections 15 are opposite each other. On the other two sides of the rectangular base plate 14, further rim sections are present, extending upwards in the same direction as the rims formed by the projections 15. This creates a rim that at least partially surrounds the base plate 14, within which the display device 6 can be arranged.A force-fit connection can be formed, whereby at the edges formed by the projections 15, the display device 6 engages at least partially behind the projections 15.

[0098] Fig. 5 bis 7 show a further embodiment of the input device 5 with the display device 6 of the Fig. 2 bis 4 The projections 15 of the input device 5 are not designed as handles that can be grasped with one hand in this case. The illustrations to the left and right of the Fig. 5 bis 7 The figures show the area of ​​the projections 15 from the side. Each projection 15 has a control stick at the top, a forward-facing rotary knob, and two push buttons as mechanically actuated operating elements 8.

[0099] Fig. 8Figure 1 shows a system with a detection device 16 designed as a camera, which is intended to detect the end of the drill string 3 in the area of ​​a target pit 17 of a borehole to be constructed. The detection device 16 has transmission means configured to transmit signals to the display device 6 and the control device 4. The signals can be displayed on the display device 6; in particular, an image captured by the camera can be displayed on the display device 6.
