Definitions

  • the invention relates to a self-propelled construction machine according to the preamble of claim 1 and a method for processing floor coverings according to the preamble of claim 13.
  • Self-propelled construction machines are known, in particular road milling machines, recyclers, stabilizers or surface miners with a machine frame, driving devices, at least one hydraulic drive system for driving the driving devices and at least one working device, in particular a milling drum for processing the floor covering.
  • existing floor coverings can be removed from roads.
  • Existing floor coverings can be restored with recyclers.
  • the stabilizers are used to prepare the substructure for road construction.
  • Coal and stone can be mined with surface miners.
  • the invention has for its object to provide a construction machine and a method for processing floor coverings, in which or in which a rocking of the construction machine is avoided, or an optimized operation of the construction machine is made possible.
  • the invention advantageously provides that a detection device is provided which detects fluctuations in the longitudinal speed of the construction machine when the construction machine is moving, with a control unit controlling the hydraulic drive system in such a way that the hydraulic drive system drives the by means of the hydraulic drive system depending on the detected fluctuations Driving devices predetermined drive speed is continuously adjusted so that the detected fluctuations are 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. However, only two driving devices can also be driven and, in addition, further non-driven driving devices can be provided.
  • 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 specified drive speed in the hydraulic drive system is to be distinguished from this. This is the drive speed specified by 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. In this way, the predetermined drive speed can be superimposed by fluctuations, which are caused, for example, by a restless running of the working device.
  • the specified drive speed is the speed that would occur with given 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 vibration by means of the detection device.
  • the detectable vibration preferably has essentially a fixed frequency. Particularly disturbing 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 on the amount of fuel and water in the tank) and other factors. This frequency is therefore variable and can therefore not generally be determined for a machine.
  • the fluctuations in the longitudinal speed affect the chassis on the one hand by noticeable “rocking movements", but on the other hand the fluctuation also affects the hydraulic drive system.
  • the movements of the machine are transferred 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 detected fluctuations.
  • the set speed need not be changed by the operator of the construction machine in order to prevent the undesired swaying of the construction machine.
  • the control unit can control the hydraulic drive system such that the frequency of the counter-vibration is matched to the frequency of the detected vibration and is out of phase with the latter.
  • the phase offset can also be continuously adjusted.
  • the control unit can control the hydraulic drive system in such a way that the frequency of the counter-vibration is in phase opposition to the frequency of the detected vibration.
  • the control unit can control the hydraulic drive system in such a way that the amplitude of the counter-vibration is matched to the amplitude of the detected vibration.
  • the undesired detected vibration can be reduced or compensated for 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 for periodically changing the predetermined drive speed.
  • the volume flow and / or the pressure in the hydraulic drive system can be controllable by means of the hydraulic pump for adapting the predetermined drive speed.
  • the swallowing volume of the hydraulic motor can also be adaptable to periodically change the specified drive speed.
  • the control unit can control the hydraulic drive system such that the drive speed specified by means of the hydraulic drive system for driving the driving device is only continuously adjusted 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 driving devices or on the machine frame and / or as a fluctuation in the volume flow and / or as a fluctuation in the pressure of the hydraulic drive.
  • the construction machine swings up, the construction machine can also tip back and forth. Vertical fluctuations can thus also be measured, which allow conclusions to be drawn about the longitudinal speed 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 changes in speed, 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.
  • a method for processing floor coverings can also be provided, with a construction machine that drives itself with the aid of driving devices, in particular road milling machines, recyclers, stabilizers or surface miners, in which the driving devices are driven by a hydraulic drive system, with one working device covering the floor covering processed.
  • driving devices in particular road milling machines, recyclers, stabilizers or surface miners
  • the driving devices are driven by a hydraulic drive system, with one working device covering the floor covering processed.
  • the fluctuations in the longitudinal speed of the construction machine can be detected as vibrations with an essentially fixed frequency.
  • the predetermined drive speed can be changed periodically in order to generate a counter-oscillation that reduces or compensates for the detected fluctuations.
  • the frequency of the counter-vibration can be adapted to the frequency of the detected vibration and be out of phase with this.
  • the frequency of the counter-vibration can be adjusted in such a way that it is in phase opposition to the frequency of the detected vibration.

  • the measured values of the detection device 44 can be transmitted to the control unit 38. This is also shown with a broken line 45.
  • the term control is to be understood in such a way that the detection device 44 records a measurement value at least once and the control unit 38 controls the hydraulic drive system 50 as a function of the detected fluctuations. However, it should also be included that the detection device records measurement values several times and the control device 38 controls the hydraulic drive system 50 as a function of the detected fluctuations.
