Definitions

  • the invention relates to a self-propelled construction machine, as well as a method for processing of ground surfaces according to the preamble of claim 1 or 11.
  • Such self-propelled construction machines for processing of ground surfaces are for example from the EP 1408158 A known.
  • the road milling machine described therein has a machine frame with a drive motor for driving driving devices and for driving working equipment.
  • the driving devices can consist of wheels or crawler tracks, which are connected to the machine frame via lifting columns.
  • a roller drive drives a milling drum for milling the bottom surfaces preferably in mating operation.
  • the milling drum can be decoupled from the drive train by means of a coupling.
  • a scraper blade In the direction of travel behind the milling drum is height adjustable a scraper blade, which can slide over the milled by the milling drum or mecanicfräsende surface. The lower edge of the scraper blade is always in the milling operation on the lowest level of the cutting circle of the milling drum.
  • Such construction machines work according to the width of the milling drum strip-shaped. This means that after a predetermined distance of the milled ground surface, the construction machine must drive back to milled an adjacent strip.
  • the peripheral speed of the milling drum is a multiple, for example, 3 times the traveling speed, so that the road construction machine can be greatly accelerated upon engagement of the milling drum.
  • the internal combustion engine Before processing the next strip, the internal combustion engine must then be brought back to operating speed. These processes are very time consuming and very annoying especially for short distances to work for the driver.
  • the constant switching operations of the clutch and the associated frequent load changes of the internal combustion engine mean Increased wear on the clutch, internal combustion engine and all components involved in the powertrain.
  • the invention is therefore an object of the invention to provide a construction machine, and a method for processing of ground surfaces, with the time required for processing a given floor area can be reduced.
  • the invention provides in an advantageous manner that the milling drum in the raised state in a traveling direction in which the direction of rotation of the milling drum coincides with the direction of rotation of the driving devices remains coupled to the roller drive and that a monitoring device monitors a distance of the milling drum to the ground surface and the raised Milling roller decoupled from the drive motor and / or decouples the driving devices of the drive motor and / or raises the machine frame and / or generates an alarm signal when the monitoring device detects a drop below a predetermined distance.
  • the milling drum can remain permanently coupled to the drive motor.
  • the milling drum can be taken out of the cut by pivoting or lifting eg via lifting columns of the driving equipment.
  • a monitoring device detects in the raised state of the milling drum, whether the predetermined for a ride without milling operation distance of the raised milling drum is maintained to the ground surface.
  • the raised, at this time further rotating milling drum is decoupled from the drive motor, so that when the milling drum should actually have ground contact, no more driving power acts on the milling drum and thus only the current rotational energy of the milling drum are destroyed got to.
  • the mass of the construction machine is sufficient to prevent the construction machine from making a jump in the direction of travel when the milling drum accidentally engages the ground surface. In this way it is ensured that when driving the construction machine without milling operation does not lose time due to the fact that a shutdown and a run-up of the drive motor must be awaited.
  • Another advantage is also that the wear of Maschinenelmenten, in particular the clutch, the internal combustion engine and all other components belonging to the drive train is reduced.
  • the milling drum mills the ground surface in mating operation, wherein a transport travel in the forward direction due to the mating run is harmless.
  • the invention is concerned with the reverse drive, in which the milling drum contrary to the prior art, despite the counter-rotation of the milling drum can remain coupled to the drive motor.
  • the monitoring of the predetermined distance by the monitoring device can be done directly or indirectly.
  • An immediate measurement is carried out, for example, by a mechanical or electronic distance measurement, while an indirect measurement of the distance, for example via machine elements of the construction machine, via push buttons or on the current position of the machine frame supporting lifting column can be done.
  • the predetermined distance of the raised milling drum to the ground surface can be monitored with at least one sensor.
  • the predetermined distance to be monitored by the monitoring device can be increased as a function of the height of the driving speed of the driving device.
  • the predetermined distance may be proportional or progressively increased as the vehicle speed increases.
  • the milling drum is raised by a predetermined amount which is greater than a minimum distance to be maintained of the milling drum from the ground surface, and that a sensing device to the bottom surface has a lower end position, the predetermined distance or a minimum distance to be maintained of the milling drum from the ground surface corresponds.
  • the monitoring device must only determine whether the sensing device leaves the lower end position, since in this case a predetermined distance or a minimum distance to be maintained of the milling drum is no longer complied with.
  • the construction machine can be provided with a lowerable relative to the milling drum sensing device which protrudes relative to the milling drum to the bottom surface by a predetermined distance in relation to the lowest point of the cutting circle of the milling drum.
  • the monitoring device generates in the raised state of the milling drum and in the simultaneously lowered state of the sensing device, for example, a control signal for decoupling the milling drum from the drive motor when the at least one sensor contact the at least one sensing device with the bottom surface or lifting the at least one sensing device through the bottom surface detected.
  • the sensing device which may consist of a button in the simplest case, is simultaneously lowered when lifting the milling drum to a lower end position corresponding to a predetermined distance or a minimum distance of the rotating milling drum to the ground surface.
  • the sensing device in turn holds a distance from the ground surface. Should the sensing device touch the ground surface during a drive of the construction machine without a milling drive, or if the sensing device is lifted by the ground surface, the monitoring device generates, for example, a control signal for decoupling the milling drum from the roller drive or drive train.
  • the sensor can detect a ground contact or the position of the sensing device, the ground contact, for example, with a structure-borne sound sensor and the position, for example, with a displacement sensor.
  • the lowest position of the sensing device can be detected with a limit switch.
  • the monitoring device can additionally or alternatively decouple the driving devices from the drive motor and / or raise the machine frame and / or trigger an alarm signal.

At least the lower end position of the sensing device is detectable by the sensor, wherein the lower end position, for example, corresponds to the minimum distance of the milling drum from the ground surface.
  • the sensing device may consist of a arranged behind the milling drum in the direction of travel Abstreifschild. In this case, the scraper blade can be lowered over the lowest position of the cutting circle of the milling drum also down.
  • the sensing device consists of a hood surrounding the milling drum and / or of a side plate arranged laterally next to an end face of the milling drum.

  • the milling drum 12 remains coupled to the drive motor 6 via the roller drive 10 and a clutch 7, see FIG that it is not necessary first to shut down the drive motor 6, preferably an internal combustion engine, to idling speed, then to decouple the milling drum 12 from the drive motor and then to raise the drive motor 6 to its operating speed again.
  • Fig. 1 shows the milling drum 12 in mating operation, in which the direction of rotation of the milling drum 12 is opposite to the direction of rotation of the driving devices 8.
  • the direction of rotation of the milling drum 12 is consistent with the direction of rotation of the driving devices 8, so that there is a risk that in an unintentional contact with the ground surface 2, the construction machine 1 is undesirably accelerated.
  • a monitoring device 14 which monitors the distance of the milling drum 12 to the bottom surface 2 and decouples the raised milling drum 12 from the roller drive 10 when the monitoring device 14 detects a drop below a predetermined distance.
  • the driving devices 8 are decoupled from the drive motor 6, or that the machine frame is raised, or that an alarm signal is generated.
  • the distance of the milling drum 12 to the bottom surface 2 can be measured directly or indirectly.
  • the detection signals from the monitoring device 14 may be fed to a machine controller or used directly to decouple the milling drum 12 or traction devices 8 from the drive motor 6, or alternatively or additionally to lifting the machine frame 4 by the lifting columns 20 or to generate an alarm signal.
