Definitions

  • Surface miners can be used to mine coal and rock.
  • the WO 03/064770 A1 discloses a construction machine, in particular for processing floors or for removing traffic areas with a milling drum equipped with a plurality of chisels, at least one signal pickup unit being assigned to at least one machine component directly or indirectly involved in the work process, the signal pickup unit indicating an operating state of the machine component detected, and that the signal recording unit is connected to a signal output device via a signal processing arrangement.
  • the invention is based on the object of creating a construction machine and a method for processing floor coverings, in which or in which the construction machine is prevented from rocking or an optimized operation of the construction machine is made possible.
  • control unit (38) is designed in such a way that it controls the hydraulic drive system as a function of the detected fluctuations in such a way that the drive speed specified by means of the hydraulic drive system for driving the driving devices is continuously adapted so that the detected fluctuations can be reduced or compensated.
  • the present invention has the advantage that the fluctuations in the construction machine are avoided or reduced, so that rocking is effectively prevented.
  • the average longitudinal speed of the construction machine can advantageously remain the same. It is therefore no longer necessary to reduce the set speed of the construction machine and the construction machine can be operated at the desired set speed.
  • At least two driving devices are preferably driven.
  • the longitudinal speed is the actual speed of the construction machine.
  • the set speed is the speed which the operator of the construction machine can set on the control unit.
  • the longitudinal speed of the construction machine is a superposition of the specified drive speed and influencing factors of the machine or the environment.
  • the specified drive speed can thus be overlaid by fluctuations that are caused, for example, by an uneven running of the working device.
  • the specified drive speed is the speed that would be set given the operating parameters of the hydraulic drive system and without any influencing factors.
  • the fluctuations in the longitudinal speed of the construction machine can be detectable as a vibration by means of the detection device.
  • the detectable oscillation preferably has essentially a fixed frequency. Particularly disruptive fluctuations are caused by vibrations that hit the resonance frequency of the machine and thus cause the machine to rock.
  • the resonance frequency of the machine depends on various operating parameters such as the current weight (again depending, among other things, on the amount of fuel and water in the tanks) and other factors. This frequency is therefore variable and can therefore not be determined for a machine in principle.
  • the fluctuations in the longitudinal speed affect the chassis on the one hand by causing noticeable "rocking movements", but on the other hand the fluctuation also affects the hydraulic drive system.
  • the movements of the machine are transmitted back into the hydraulic circuit via the drives and the hydraulic motors and can also be detected there as fluctuations in the pressure or in the volume flow.
  • the control unit can control the hydraulic drive system in such a way that the predetermined drive speed is changed periodically in order to generate a counter-oscillation which reduces or compensates for the fluctuations detected.
  • the set speed does not have to be changed by the operator of the construction machine in order to prevent the construction machine from swaying undesirably.
  • the control unit can control the hydraulic drive system in such a way that the frequency of the counter-oscillation is adapted to the frequency of the detected oscillation and is out of phase with it.

  • the control unit can control the hydraulic drive system in such a way that the amplitude of the counter-oscillation is adapted to the amplitude of the detected oscillation.
  • the undesired detected oscillation can be reduced or compensated particularly effectively.
  • the hydraulic drive system can comprise at least one hydraulic pump and at least one hydraulic motor. Furthermore, the hydraulic drive system can also include lines and other elements, such as pressure accumulators.
  • the at least one hydraulic pump can be an axial piston pump.
  • the hydraulic motor can also be an axial piston motor.
  • the control unit can control the volume flow and / or the pressure in the hydraulic drive system in order to periodically change the specified drive speed.
  • the hydraulic pump can be designed in such a way that it controls the volume flow and / or the pressure in the hydraulic drive system in order to adapt the predetermined drive speed.
  • the at least one hydraulic motor can also be designed in such a way that the absorption volume can be set for the periodic change in the predetermined drive speed.
  • the control unit can control the hydraulic drive system in such a way that the drive speed predetermined by means of the hydraulic drive system for driving the driving device is only continuously adapted when the detected vibration exceeds a predefined amplitude.
  • the detection device can detect fluctuations in the longitudinal speed as fluctuations in the longitudinal speed around the set speed.
  • the detection device can detect the fluctuations on the travel devices or on the machine frame and / or as fluctuations in the volume flow and / or as fluctuations in the pressure of the hydraulic drive. If the construction machine rocks, the construction machine can also tilt back and forth. Vertical fluctuations can thus also be measured, which allow conclusions to be drawn about the longitudinal velocity fluctuations.
  • the detection device can comprise a pick-up sensor and / or an acceleration sensor and / or a measuring device for measuring the pressure fluctuations in the hydraulic drive system.
  • An accelerometer measures the speed changes, whereby the fluctuations in the longitudinal speed can be determined. Furthermore, for example, changes in the volume flow of the hydraulic fluid in the hydraulic system can be measured with a corresponding sensor.

  • the invention advantageously provides that, depending on the detected fluctuations, the drive speed specified by the hydraulic drive system for the driving devices is continuously adapted by means of a control unit, so that the detected fluctuations of the construction machine are reduced or compensated.
  • the fluctuations in the longitudinal speed of the construction machine can be detected as vibrations with an essentially fixed frequency.
  • the specified drive speed can be changed periodically in order to generate a counter-oscillation which reduces or compensates for the fluctuations detected.

  15. Procédé selon la revendication 13 ou 14, caractérisé en ce que la vitesse d'entraînement (vAntrieb) prédéterminée est modifiée périodiquement afin de produire une contre-vibration, laquelle réduit ou compense les fluctuations détectées.
  16. Procédé selon la revendication 15, caractérisé en ce que la fréquence de la contre-vibration est ajustée à la fréquence de la vibration détectée et est déphasée, de préférence en opposition de phase par rapport à celle-ci.
