Definitions

  • the invention relates to a civil engineering machine, in particular a drilling rig, with a mobile carrier device, a mast or boom arm which is arranged on the carrier device, and a civil engineering tool which is adjustably arranged on the mast or boom arm for carrying out a civil engineering measure.
  • the civil engineering machine also has a control unit and an operating cabin for at least one operator with at least one display device, in particular a monitor, which is connected to the control unit and is designed to display operating data recorded by the control unit to a machine operator in several display fields on the at least one display device.
  • the invention also relates to a method for operating a civil engineering machine.
  • the civil engineering machine can be, for example, a diaphragm wall cutter, a pile driver, a cable excavator, a grab excavator, but also a mobile crane or a mobile boom crane.
  • a foundation element can be formed, for example, by creating a hole in the ground, such as a borehole or a milling slot, with the hole then being filled with a hardenable medium, in particular a mortar, to form a foundation pile or a diaphragm wall segment, if necessary with additional reinforcement.
  • a foundation element can also be created by ramming or vibrating, such as a foundation pile or a plank.
  • a foundation element is not limited to a load-bearing or load-bearing function, but can alternatively or additionally also take on a sealing function and/or other tasks, as is known, for example, from special foundation engineering when enclosing excavation pits with sealing walls.
  • Such civil engineering machines are known, for example, from EP 3299523 A1 , the EP 3296467 A1 or the JP 2022-077258 A known.
  • Display devices in civil engineering machines are used to show the machine operator operating data that is recorded by the control unit from internal and/or external sensors so that he can control the civil engineering machine effectively and safely.
  • the data can be, for example, the current depth of the civil engineering tool, the torque of a winch or the temperature of the oil in an oil circuit.
  • the invention is therefore based on the object of specifying a civil engineering machine and a method for operating a civil engineering machine, which facilitates the use of a civil engineering machine by different machine operators.
  • control unit is designed in such a way that a display, an arrangement and/or a type of display fields can be changed and set by a machine operator, and can be stored in a data memory as a personal configuration of the machine operator independently of the control unit.
  • independent of the control unit also means that the configuration can be stored independently of the civil engineering machine in which the control unit is provided.
  • a basic idea of the invention is to allow the machine operator to arrange and configure the displays on the display device in a user-specific manner. This means that an experienced machine operator who carries out complicated tasks can have certain information relevant to his work displayed, whereas a less experienced machine operator can put together the display device and the information shown there in such a way that it also shows the appropriate data for him, including other data.
  • the invention makes it possible to adapt the display device to the respective machine operator, but also to the respective work order. So that this adaptation is not lost, it can be stored according to the invention.
  • the invention provides that the information required for the user-specific display is not necessarily stored on the civil engineering machine or in the control unit, but independently of it.
  • control unit has a transmission device, in particular a data transmission device, with which data for the personal configuration of the display fields can be transmitted to a data storage device outside the control unit.
  • a transmission device in particular a data transmission device, with which data for the personal configuration of the display fields can be transmitted to a data storage device outside the control unit.
  • the information for the user-specific configuration is not stored in the control unit itself and not necessarily in the civil engineering machine by means of the transmission device. This makes it possible to access the relevant information centrally.
  • the transmission device is designed to store the data relating to the personal configuration on a mobile data carrier, a mobile computer unit, a central data depository and/or in a Cloud storage. This is done in order to save the corresponding data there.
  • the elements in the above list can be seen as alternative ways in which the data for the personal configuration can be saved.
  • a mobile data carrier can be understood as, for example, a machine key, a USB stick or another data storage device that can be written to wirelessly, for example via Bluetooth, RFID or NFC technologies.
  • a mobile computer unit can be seen as, for example, a laptop, a tablet computer or a smartphone.
  • the display device can be designed in any way. This can be a monitor, for example, but also other types of display devices, such as data glasses, a head-up display or a tablet.
  • the display device is preferably designed to show numbers, functions, graphics, animations and/or photo and video images.
  • any information can be displayed in a suitable manner on the display device. It is also possible for the machine operator to define the type of display of certain data himself. For example, the temperature of the engine oil of the civil engineering machine can be displayed as a number, but also as a bar chart and/or in the form of a circular display instrument. The machine operator can set the exact design according to what is easiest for him to read.
  • a pre-selection of retrievable operating data, possible display types and/or arrangement options is stored in the control unit and/or can be retrieved from it and can be retrieved and selected by the machine operator to create the personal configuration.
  • a type of A toolbox can be provided from which the individual machine operator can put together the display and the type of display that is best for him in his experience in the respective work situation. Templates can also be provided here. This makes such a setting easier for less experienced machine operators in particular.
  • operating data can be understood as information on current and past operating/machine states, for example, but also information on production data such as details on foundation elements to be created or soil information.
  • the control unit has a display configuration mode, wherein when the display configuration mode is activated, the display on the at least one display device can be changed and saved.
  • the display configuration mode can be used to influence, for example, the position or type of a specific display on the display device.
  • the display device consists of several monitors, for example, so that some displays are displayed on the first monitor while other displays are displayed on the second monitor.
  • different types of display devices can also be combined, for example a fixed monitor and a tablet PC, which can also be removed from the operator's cabin.
  • the size, type, position and/or color of the display field is adjustable.
  • the graphical representation of the information can also be adjustable, so that some information is displayed as digits or numbers, others as graphics, such as bars.
  • a particularly simple setting is achieved if the at least one display device is designed as a touchscreen on which the display fields can be changed and/or adjusted directly by touching the display device. In this way, an intuitive setting of the individual display fields can be achieved particularly easily.
  • a setting via a mouse or a touchpad can also be made via a web interface or a mobile phone app.
  • an identification device is arranged by means of which a machine operator who wishes to operate the civil engineering machine can be identified.
  • the control unit can be designed to automatically and/or on request call up a personal configuration of the identified machine operator in order to bring about a desired display on the at least one display device.
  • the call can be made from an internal memory in the control unit or the civil engineering machine, but also from an external memory that is made available via an interface. This can also be, for example, a central data storage device that is provided on servers of the manufacturer of the construction machine or the operating company.
  • an identification device it is particularly easy to assign the corresponding user-specific setting of the display device to a user and make it available.
  • a user name optionally in conjunction with a password, a fingerprint sensor or a correspondingly coded key for the civil engineering machine can be used as an identification device.
  • the invention is particularly advantageous when used in conjunction with an arrangement that includes several civil engineering machines that can be selected by a machine operator.
  • the advantages of the invention then arise in a particular way, since it is not necessary to ensure that a machine operator uses the same civil engineering machine each time. It is therefore possible for a machine operator to use different civil engineering machines and actively transfer his desired configuration to the civil engineering machine or to call it up there, so that he has his usual display available on the display device.
  • a central data storage location can be understood as, for example, a database that can be queried via the Internet. It is not necessary that there is just one database; several databases can also be available that can be used alternatively to one another or act as a backup for one another.
  • the invention further relates to a method for operating a civil engineering machine as described above or an arrangement of this type. It is provided that at least one machine operator creates a personal configuration for the display fields on the at least one display device and stores it in a data storage device. It is also provided that, upon request and/or through automatic identification of the machine operator, the control unit retrieves the personal configuration of the machine operator from the data storage device and a corresponding display is effected in accordance with the personal configuration on the at least one display device.
  • a machine operator can also be regarded as an administrator or master user who defines individual personal configurations for different machine operators.
  • the settings of the different machine operators can also be copied, so that different display fields or different contents are shown on the at least one display device for an experienced group of machine operators than for inexperienced machine operators.
  • the same also applies to different operating modes of the civil engineering machine. For example, with a trench wall cutter that cuts into hard rock, different data on the display fields are of interest to the machine operator than with a trench wall cutter that creates a trench wall in sandy subsoil.
  • the data storage can be located in the civil engineering machine or remote from it.
  • a civil engineering machine 10 according to the invention which can be used as a drilling device according to Fig. 1 is designed, has an undercarriage 12, preferably designed as a crawler chassis, and an upper carriage 14 rotatably mounted thereon.

  • a second drive 26 with a sleeve-shaped rotary connection 27 for establishing a rotationally fixed connection to a support tube 4 can be provided on the carriage 20.
  • the second drive 26 can, for example, essentially consist of a gear connection to the first drilling drive 22 with the hydraulic motor 24 in order to apply a torque to the rotary connection 27 and thus the support tube 4.
  • the approximately sleeve-shaped first drilling drive 22 can, for example, be penetrated by a drill rod 30, which can be designed as a Kelly rod with external drive strips.
  • the drill rod 30 can have an upper suspension 32, with which the drill rod 30 is connected to a main cable 39.

  • the carriage 20 can be moved up or down along a guide of the mast 18 by the feed winch 36.
  • a drilling tool is attached to the underside of the drill rod 30 as a civil engineering tool 34 for removing soil material.
  • the civil engineering tool 34 is in the illustrated embodiment according to Fig. 1 designed as a drilling bucket.
  • the diameter of the drilling tool is designed such that it can be inserted into the inner cavity of the support tube 4.
  • the civil engineering machine 10 can be used to create a cased borehole in the ground 1.
  • a hardenable mass 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 preferably be pulled out of the ground 1 before hardening.
  • a schematic example of a display device 50 is shown. This shows five display fields 51 as an example, each of which shows different information.
  • the middle display field 51 for example, shows the current depth of a borehole and the drilling depth to be achieved in graphical form.
  • a display field 51 is shown, which has a round element that shows, for example, the current torque of the motor.
  • a display field 51 with a bar graph is shown. This can, for example, show the current transmission oil pressure in a clear manner.

  • the display device 50 can thus be specially configured for the respective machine user so that the data required for his current task is displayed in a particularly advantageous manner. Personal preferences can also be taken into account in this way.
  • not only one display device 50 can be used, but also several, which can be arranged one above the other or next to one another, for example. This also makes it possible to move a display field 51 from a main display device to a secondary display device if the information in the display field 51 is rarely used.
