Definitions

  • the present invention relates to a device with a carrier device and an attachment, such as a construction machine, such.
  • an attachment such as a construction machine, such.
  • a crawler excavator with a drill mount as an attachment, according to the preamble of claim 1.
  • Attachments such as drills, spray guns, grapples, harvesters, etc., for attachment to suitable carrier equipment, such as crawler excavators, walking excavators, wheeled excavators, mini and midi excavators, two-way excavators, mobile cranes, telescopic loaders, etc. are known in the art.
  • suitable carrier equipment such as crawler excavators, walking excavators, wheeled excavators, mini and midi excavators, two-way excavators, mobile cranes, telescopic loaders, etc.
  • the operation of the attachment is usually done by hand, cable or radio remote control, while the carrier device is conventionally operated in a cab, or by its own hand, cable, or radio remote control.
  • two or more persons for example one or more operators or instructors are required for positioning or operating the equipment (attachment and carrier device).
  • two operators are currently required in drilling application, a first operator for the drill and a second operator for the carrier.
  • this is uneconomical due to the increased use of personnel.
  • frequent change of location for example due to inadequate control of the drilling operations, is necessary, resulting in an additional loss of time.
  • there is often danger to life as the operator of the attachment must be within the danger zone, or because of visual problems such as dust, unclear terrain, structures, etc. the communication of the referrer with the operator of the carrier device is difficult.
  • the increased noise emission at construction sites also contributes to this.
  • the object of the present invention is therefore to develop a holistic operating and control concept with universally applicable control systems and the associated actuators, such as directional valves, etc. for all known carrier equipment and attachments, regardless of the control system of the carrier device and the attachment, wherein the Functions from the existing cab or from the control station on a central control unit are mapped.
  • all relevant safety and locking systems such as brakes, emergency stop systems, etc. must be maintained and the economic implementation by using largely constant components, such as in a modular system can be done.
  • All required components of the superior system should have the most compact dimensions and should have a sufficiently high resistance to external influences, such as moisture, dust, dirt, vibration, shock, corrosion, chemical resistance, etc., to be installed in the respective carrier and attachments to be able to.
  • the inventive apparatus comprises an attachment and a carrier mechanically connected to the attachment, and at least one receiver mechanically fixed to or on the carrier, or on or at the Attachment is mechanically attached. Furthermore, the device has at least one remote control that can communicate with the at least one receiver and optionally communicates with it, so that the at least one receiver transmits electrical signals to the carrier device and / or to the attachment when the at least one remote control with the at least a receiver communicates.
  • the at least one receiver is mechanically fastened or arranged on or on the carrier device, it can thus in the preferred embodiment transmit electrical signals to the attachment.

  • the carrier device is advantageously designed to move the attachment.
  • the remote control can, for example, communicate with a receiver mounted on the carrier device and also control the attachment via already existing additional functions.
  • the remote control may, for example, have a transmitter, but possibly also several transmitters which transmit at different frequencies.

  • the carrier device may be, for example, a hydraulic unit.
  • the first receiver communicates with the carrier via control signals which cause the implement to move with the carrier when the remote controller transmits to the first receiver a first signal intended therefor.
  • the second receiver transmits control signals to the attachment, the control signals causing movement of parts of the attachment when the remote control transmits to the second receiver a dedicated signal, for example a second signal or a corresponding data set, whereby both the functions / movements of the attachment, or of parts of the attachment as well as the functions / movement of the carrier device are controlled with the same remote control, advantageously further additional functions, such as engine start, pressure readings, oil pressure, temperatures, etc. are communicated with the above-mentioned remote control.
  • the movement of the attachment as a whole unit with the carrier device is advantageously controlled independently of the movement of, for example, parts of the attachment or the function of the attachment.
  • Such a device has a number of different advantages: for example, the operator can have an operating position outside the danger zone, for example outside of Use high voltage power lines, rockfall, landslides, contaminated areas, etc. without limiting operating convenience.
  • the operator can choose his operating position with an optimal view of the current events himself and move without restriction by noise and / or dust sources. It is also only a single operator required in such a device, resulting in an increased efficiency due to the savings in personnel, since, for example, a referrer is no longer required.
  • the device thus achieves an increased operating and positioning speed as well as an increased positioning accuracy by higher-level control, as well as an increased operating quality, because only a single and higher-level operation is required.
  • the operator no longer has to enter the cab of, for example, an excavator in order to position the attachment.
  • the resulting lower physical load allows the operator to work safer and error-free.
  • an energy saving can be effected, for example, when engine start / stop functions, or speed reductions are provided.
