Description

Technical Field

[0001] The invention relates to an underground engineering machine, in particular a drilling device, which has: a mobile supporting device; a mast or a cantilever, which is arranged on the supporting device; and an underground engineering tool, which is adjustably arranged on the mast or the cantilever for carrying out underground engineering measures. In addition, the underground engineering machine has a control unit and an operating room for at least one operator, which has at least one display device, in particular a display, which is connected to the control unit and is designed to display operating data detected by the control unit to the machine operator in a plurality of display areas on the at least one display device. In addition, the invention relates to a method for operating an underground engineering machine. Background Art

[0002] The underground construction machine may be, for example, a slotted wall milling machine, a pile driver, a cable excavator, a grab excavator, but also a mobile crane or a mobile jib crane.

[0003] Underground construction machines, in particular underground construction machines for constructing foundations in the ground, are already known. For example, the foundation element can be formed by constructing a hole in the ground (e.g. drilling or milling a groove), wherein the hole is then filled with a hardenable medium, in particular mortar, to form a foundation pile or a slotted wall section, if applicable with additional reinforcement. The foundation element can also be implemented by ramming or vibrating (e.g. foundation piles or wooden boards). The foundation element is not limited to a load-absorbing or load-bearing function, but can alternatively or additionally also assume a sealing function and other tasks, as is known from special underground engineering, for example in a foundation pit enclosure with a sealing wall.

[0004] Today, known underground construction machines are equipped with electronic control units that make the operation of the underground construction machine easier for the machine operator or can even take over the operation of the underground construction machine partially or completely automatically. Various operating data can be detected via sensors and transmitted to the control unit. Control commands can be output to the corresponding actuators, in particular drives and adjusting cylinders, via corresponding data lines.

[0005] Such underground construction machines are known, for example, from EP 3 299 523 A1 and EP 3 296 467 A1.

[0006] The display device in the underground construction machine is used to display the operating data detected by the control unit from internal and / or external sensors to the machine operator, so that the machine operator can control the underground construction machine accordingly efficiently and safely. The data can be, for example, the current depth of the underground construction tool, the torque of the winch or the temperature of the oil in the oil circulation system.

[0007] On large construction sites, a large number of underground construction machines are usually used in parallel, which are controlled by different machine operators. These machine operators have different levels of experience and also construct different foundation elements. Depending on the work assignment and experience, different information is relevant to the machine operator. Summary of the invention

[0008] The invention is therefore based on the object of specifying an underground construction machine and a method for operating an underground construction machine which facilitate the use of the underground construction machine by different machine operators.

[0009] This object is achieved on the one hand by an underground construction machine having the features of claim 1 and on the other hand by a method having the features of claim 12 .

[0010] Preferred embodiments of the invention are indicated in the dependent claims and in the drawings and their description.

[0011] According to the invention, it is provided that the control unit is designed in such a way that the display, arrangement and / or type of the display fields can be changed and set by the machine operator and can be stored as a personal configuration of the machine operator independently of the control unit. Independent of the control unit in the sense of the invention also means that the configuration can be stored independently of the underground construction machine in which the control unit is arranged.

[0012] The basic idea of ​​the invention is to allow the machine operator to arrange and configure the display on the display device in a user-specific manner. This allows an experienced machine operator who performs complex tasks to be shown specific information that is relevant to his work, while an inexperienced machine operator can arrange the display device and the information presented there in such a way that it also displays suitable data and other data for the inexperienced machine operator. In other words, the invention makes it possible to adapt the display device to the respective machine operator, but also to the respective work assignment. In order not to lose this adaptation, according to the invention, the adaptation can be stored. In order to also enable a cross-device display, according to the invention, it is provided that the information required for the user-specific display is not necessarily stored on the underground engineering machine or in the control unit, but is stored independently of the underground engineering machine or the control unit.

[0013] The control unit advantageously has a transmission device, in particular a data transmission device, by means of which data for the individual configuration of the display panel can be transmitted to a data memory outside the control unit. In other words, according to the invention, it is provided that the information for the user-specific configuration is not stored in the control unit itself and not necessarily in the underground construction machine by means of the transmission device. This makes it possible to centrally access the corresponding information.

[0014] It is preferred that the transmission device is configured to transmit the data configured for an individual to a mobile data carrier, a mobile computer unit, a central data storage point and / or a cloud storage. This is achieved so that the corresponding data can be stored there. The above-mentioned elements can be regarded as the following alternative feasible schemes, and the data configured for an individual can be stored at the alternative feasible scheme. However, it is also feasible to use not only one of the above, but also a plurality of the above. In the sense of the present invention, the mobile data carrier can be understood as a machine key, a USB flash drive or other data storage device that can be written wirelessly, for example, via Bluetooth, RFID or NFC technology. In the sense of the present invention, the mobile computer unit can be regarded as a laptop, a tablet computer or a smart phone, for example. In this way, it can be realized that the data configured for an individual is stored in different places, so that the individual configuration can be re-transcribed to the underground engineering machine depending on the exact field of use. This can also be connected to the control unit via the transmission device in a similar manner, for example.

[0015] In principle, the display device can be designed in any desired manner. It can be, for example, a monitor, but can also be another type of display device, such as data glasses, a head-up display or a tablet computer. The display device is preferably designed to display numbers, functions, graphics, animations and / or photo images and video images.

[0016] In other words, any information can be presented on the display device in a suitable manner. It is also possible for the machine operator to define the manner in which specific data is displayed. For example, the temperature of the engine oil of an underground construction machine can be implemented as a number, but can also be implemented as a bar graph and / or in the form of a circular display instrument. The machine operator can set the exact embodiment according to the manner that is most easily readable for the machine operator.

[0017] In order to facilitate the setting of the display device, it can be provided that the presets of the available operating data, possible display types and / or arrangement possibilities are stored in the control unit and / or can be called up from the control unit and can be called up and selected by the machine operator for forming a personal configuration. In other words, in the control unit or as an alternative thereto, a toolbox can be provided in an external memory, from which the respective machine operator arranges the display parts and display types which are best for the machine operator in the corresponding working situation according to his experience. Templates can also be provided here. This makes such setting easier in particular for inexperienced machine operators. In the sense of the invention, operating data can be understood, for example, as information about current and past operating states / machine states, but also as information about production data, such as details about the foundation elements to be built or land information.

[0018] Preferably, the control unit includes a display configuration mode, wherein, when the display configuration mode is activated, the display portion on the at least one display device is modifiable and storable. In other words, the position or type of a specific display portion on the display device can be affected, for example, via the display configuration mode. It is also feasible to enlarge or reduce a specific display portion (which may also be referred to as a window or a widget), and / or to present a specific display portion at different parts of the display device. If the display device is, for example, composed of a plurality of displays, some display portions can be displayed on a first display, while other display portions can be displayed on a second display, this is particularly advantageous. In this case, different types of display devices can also be combined, for example, a fixed display and a tablet personal computer that can also be removed from the operating room can be combined.

[0019] Advantageously, for example, the size, type, position and / or color of the display area is configurable. The graphical presentation of information may also be configurable, so that some information may be presented as numbers or figures and other information may be presented as graphics (eg bar graphs).

[0020] A particularly simple setting results if the at least one display device is designed as a touch screen on which the display fields can be changed and / or set directly by touching the display device. In this way, an intuitive setting of the individual display fields can be achieved particularly easily. However, the setting can also be carried out via a mouse or a touchpad as an alternative or in addition. The setting can also be carried out via a web interface or a mobile phone application.

[0021] In an advantageous embodiment, an identification device is arranged, by which a machine operator who wants to operate an underground construction machine can be identified. In addition, the control unit can be designed to automatically and / or upon request call up the personal configuration of the identified machine operator in order to cause the desired display to be performed on the at least one display device. The call can be made from an internal memory in the control unit or the underground construction machine, but can also be made from an external memory provided via an interface. For example, this can also involve a central data memory arranged on a server of a construction machine manufacturer or an operating company. By using the identification device, it is particularly easy to associate the corresponding user-specific settings of the display device to the user and provide them to the user. In the simplest case, as the identification device, for example, a user name (optionally used in combination with a password), a fingerprint sensor or a corresponding coded key for the underground construction machine can be used.

[0022] The invention is particularly advantageous when used in conjunction with an arrangement comprising a plurality of underground construction machines which can be selected by a machine operator. The advantages according to the invention are then obtained in an advantageous manner, since it is not necessary to strictly ensure that the machine operator uses the same underground construction machine in each case. It is thus possible for the machine operator to use different underground construction machines and to actively transfer the respectively desired configuration to the underground construction machine or to call up the configuration there, so that the machine operator can obtain the presentation to which he is accustomed on the display device.

[0023] Advantageously, a central data storage point is provided and the underground construction machine can be connected to it to store and call up data configured for the individual. In this way, it is possible in a simple manner to provide each machine operator with his or her specific presentation on the display device. Alternatively, it is also possible to carry the corresponding configuration with the aid of a data carrier, so that the machine operator actively transmits these data when starting the underground construction machine, or the control unit calls up these data. In principle, a central data storage point in the sense of the invention can be understood as, for example, a database that can be called up via the Internet. It is not necessary to involve just one database here, but it is also possible to provide a plurality of databases that can be used alternatively to each other or serve as a safeguard for each other.

[0024] The invention further relates to a method for operating an underground construction machine or such an assembly as has been described above. It is provided that at least one machine operator creates a personal configuration for a display area on at least one display device and stores it in a data memory. It is further provided that, upon request of the machine operator and / or by automatic recognition of the machine operator, the control unit calls up the personal configuration of the machine operator from the data memory and causes a corresponding display to be performed on the at least one display device according to the personal configuration.

[0025] In the sense of the invention, a machine operator can also be considered as an administrator or master user who specifies individual personal configurations for different machine operators. In this case, the settings of different machine operators can also be copied so that different display areas or different contents are presented on the at least one display device for an experienced group of machine operators than for inexperienced machine operators. The same applies to different operating modes of the underground construction machine. For example, in a slotting wall milling machine milling in hard rock, different data are of interest to the machine operator on the display area than in a slotting wall milling machine constructing slotted walls in sandy ground. The data memory can be present in the underground construction machine or remote from it. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The present invention will be further explained below based on preferred embodiments. These embodiments are shown in the schematic diagrams listed. In these drawings:

[0027] Figure 1 shows a schematic side view of an underground construction machine according to the invention;

[0028] Figure 2 A schematic diagram showing a display device with different display areas;

[0029] Figure 3 A schematic diagram showing possible data transmission paths. DETAILED DESCRIPTION

[0030] According to the invention, the underground construction machine 10 (which is exemplarily configured according to Figure 1 The drilling device of the present invention has a substructure 12 which is preferably designed as a crawler-type running gear and a superstructure 14 which is rotatably supported on the substructure. The substructure 12 and the superstructure 14 form a support device 15. The drive assembly and the operating console for the machine operator of the underground construction machine 10 can be arranged on the superstructure 14 in a known manner. A control unit 40 and a display device 50 (in particular a display) can be arranged in the operating console.

[0031] The substantially vertical mast 18 with the upper mast head 19 can be adjustably mounted on the front side of the superstructure 14 via an articulated kinematic mechanism 16 with a neck cylinder. A slide 20 is slidably mounted along the front side of the mast 18. A first drilling drive 22 can be arranged on the slide 20, which can have a hydraulic motor 24. In addition, a second drive 26 can be arranged on the slide 20, which has a sleeve-shaped rotary connection 27 for establishing a rotationally fixed connection with the support tube 4. The second drive 26 can, for example, essentially consist of a gear connection to the first drilling drive 22 with the hydraulic motor 24, so that a torque can be applied to the rotary connection 27 and thus to the support tube 4.

[0032] The first, approximately sleeve-shaped drilling drive 22 can be passed through by way of example by a drill rod 30, which can be designed as a kelly with an external driving strip. The drill rod 30 can have an upper suspension 32, with which the drill rod 30 is connected to a main rope 39. The main rope 39 can be guided via a reversing pulley at the mast head 19 to a main winch 38 at the upper side of the superstructure 14. By operating the main winch 38, the drill rod 30 can be moved vertically.

[0033] The carriage 20 can be connected to a feed rope 37, which can be guided along the mast 18 above and below the carriage 20 and operated by a feed winch 36. By means of the feed winch 36, the carriage 20 can be moved along the guide of the mast 18 upwards or downwards.

[0034] A drilling tool as underground engineering tool 34 is arranged on the underside of the drill rod 30 for removing ground material. Figure 1 In the exemplary embodiment shown, the underground engineering tool 34 is designed as a drilling bucket. The diameter of the drilling tool is designed in this case so that it can be introduced into the inner hollow space of the support tube 4.

[0035] The underground construction machine 10 can be used to construct a casing borehole in the ground 1. In order to form a foundation element in the ground 1, a hardenable material can be introduced into the borehole, which then hardens to form the foundation element. The support pipe 4 can remain in the borehole as part of the foundation element or can be preferably pulled out of the ground 1 before hardening.

[0036] exist Figure 2 , a schematic example for a display device 50 is shown. Five display fields 51 are shown in this figure by way of example, each of which presents different information. For example, the current drilling depth and the drilling depth to be reached are shown in a graphical representation in the middle display field 51. To the right of this, in the upper area, a display field 51 is shown which has a circular element which reflects, for example, the current motor torque.

[0037] Below it, a display area 51 with a bar graph is drawn. This display area can, for example, display the current transmission oil pressure in an intuitive manner.

[0038] A digital display is shown in the upper region on the left side of the display device 50. A display field 51 is shown in the lower region, which displays a trend curve, for example a trend curve of the drilling depth over time.

[0039] Based on the present invention, it is possible to arrange different display areas 51 on the display device 50 in any manner. Different display areas 51 can also be added and configured via corresponding functions. The display mode can also be selected. This also applies, for example, to the selection, position, level of detail, etc. of the displayed information.

[0040] In this way, the display device 50 can be configured specifically for the respective machine user, so that the data necessary for his current task are displayed particularly advantageously. Personal preferences can also be taken into account in this way.

[0041] Within the scope of the invention, not only one display device 50 but also multiple display devices can be used, which can be arranged, for example, one above the other or side by side. It is thus also possible to move a display area 51 of a main display device to a parallel display device if the information in this display area 51 is rarely used.

[0042] exist Figure 3 2 shows a schematic diagram which illustrates an exemplary basic structure of an underground construction machine 10 according to the invention with regard to the data flow of a display device 50 .

[0043] The central element here is the control unit 40. The control unit obtains data via a large number of sensor devices 48. The sensor devices 48 can be, for example, sensors for torque or temperature sensors. These sensor devices do not necessarily have to be arranged at the underground construction machine according to the invention, but can also be external sensors. The transmission to the control unit 40 can be carried out not only wired but also wirelessly. Other information sources, such as project plans or engineering plans, can also be used by the control unit 40. In general, the sensor devices 48 can even be regarded as data sources.

[0044] These data and information are output via the control unit 40 to (in this case) two display devices 50. On the display devices 50, the data are presented in a display area 51, as previously described with reference to Figure 2 The machine user can hereby select which data and information are to be displayed to him and also the form in which these data and information are to be displayed.

[0045] This configuration can be stored in an internal memory 42 in the underground construction machine 10 by means of the control unit 40. Alternatively or additionally, the configuration can also be transmitted to an external memory 44 by means of a transmission device 60. The external memory 44 can be, for example, a data carrier, but can also be a storage unit in the cloud, a server, etc. The design of the transmission device 60 in this regard can accordingly be provided for wired transmission, but can also be provided for wireless transmission. For example, the transmission device 60 can be designed in a simple manner in the form of a modem, which transmits data to a server via a mobile radio network.

[0046] If the machine operator starts the underground construction machine 10, he can load his configuration from the internal memory 42 or from the external memory 44 via the transmission device 60, so that the display area 51 is presented in the most intuitive way for him on the display device 50. The display area 51 can be arranged on the display device 50 preferably via a touch screen, if the display device 50 is designed in this way. Alternatively, control can also be carried out for this purpose by means of a rotating element, a sliding part or other machine-machine communication device.

[0047] An identification device may also be provided, which may be associated with the control unit and by means of which it is possible to see which machine operator is operating the underground construction machine 10, wherein based on this information, his personal configuration is loaded into the display device 50. This can be done both locally from the internal memory 42 and via the correspondingly accessible external memory 44.

[0048] As described, the external memory 44 can also be used simultaneously by different underground construction machines 10 , so that configuration data can be transferred from one underground construction machine 10 to another underground construction machine.

[0049] With the aid of the underground construction machine according to the invention and the corresponding method, it is possible to present data specific to the machine operator on a display device and thus to achieve more efficient work.
