Definitions

  • the invention relates to a road paver with a screed, which is provided with actuators for adjusting the height and incline of the screed and sensors therefor, the output signals of the sensors serving as actual values for the actuators according to predeterminable setpoints controlling controllers.
  • control devices consist of height and inclination controls, which each activate the actuating cylinder on the left and right paver side via solenoid valves in the event of a deviation from the desired height or the desired bank angle, so that a corresponding correction adjustment on the towing arms via which the screed is articulated in height on the chassis of the paver is done.
  • reference wires are usually arranged along the installation section, on which a sensor for the actual value determination for the height controller, whose setpoint is manually adjusted via a spindle, is guided along one or both sides of the paver.
  • the Clamping the reference wires is very complex and leads to the fact that the smallest possible number of support points is used.
  • the reference wire inevitably experiences a sag under its own weight and the weight of the height sensor and also when the temperature rises, which causes corresponding unevenness.
  • the object of the invention is to provide a paver of the type mentioned at the outset, which makes it possible to automatically maintain bank values, for example in transition sections, according to a predetermined profile plan.
  • a displacement measuring device is provided, the output signals of which can be fed to an on-board computer, the on-board computer along with a data memory for storing the length of a transition section and the difference in cross slope that is to be maintained between the start and end point of the transition section the installation path is provided and the setpoints calculated and predeterminable for the inclination controller by the on-board computer can be changed continuously by the on-board computer depending on the start and end point.
  • an on-board computer enters the length of the transition section and the difference in the cross slope that is to be maintained between the start and end point of the transition section.
  • the on-board computer calculates the required cross slope for each point of the transition section and gives the calculated value as a target value to a corresponding inclination controller, so that there is a uniform and continuous change in inclination and thus a corresponding improvement in the quality of the installed road.
  • the existing base to be built over is expediently used as a reference for the installation height. Any unevenness in the base is determined in advance by leveling at defined measuring points (stations) along the road to be manufactured and entered into the on-board computer as station-related height corrections.
  • station-related height corrections When installing the layer, the respective height of the base and the station are determined in particular by a measuring wheel which is arranged on the probe arm of a height controller.
  • the height correction values are determined on a pa along the longitudinal axis of the road parallel line on which the measuring wheel runs during installation.
  • the corresponding height correction is carried out for each station by means of actuators acting on the screed, the height correction being changed continuously between one station from one entered value to another depending on the distance the paver has traveled. In this way, the existing unevenness of the underlay is compensated and a practically flat layer is installed.
  • At least one measuring wheel is used simultaneously as a height sensor, the use of reference wires or the like can be dispensed with.
  • the on-board computer can be used to determine, prepare and save data that is important for the use of the road paver in the manufacture of road pavements and to make it available at every point on the paving route. This includes the quantity of mix actually installed since the start of paving or its deviation from a target quantity, the current and average speed of advance and the resulting efficiency of paving.
  • the road paver 1 shown schematically in FIGS. 1 and 2 comprises a screed 2 which is articulated in a higher adjustable manner by means of draw arms 3 on the chassis 5 of the road paver 1, for example provided with a crawler track 4.
  • Paving material which is picked up by a material bucket 6 at the front end of the chassis 5, is fed to the screed 2, which is located at the rear of the chassis 5, and distributed over the width of the screed 2 by means of a spreading screw 7, which compresses the paving material with built-in predetermined layer thickness.
  • Actuators 8 in the form of actuating cylinders with pistons which can be acted upon on both sides and corresponding directional valves 9 for adjusting the piston and thus the height of the screed 2 with height regulators 10 serve to adjust the height of the screed 2 on one or both sides thereof.
  • An inclinometer on the screed 2 the actual values for the cross slope of the screed 2 for provides a tilt controller 11 is integrated in the latter.
  • the inclination controller 11 regulates the transverse inclination of the screed 2 in accordance with a predefined setpoint via one of the actuators 8, the other being used for height regulation.
  • one or two measuring wheels 12 are provided for measuring the distance covered by the road paver 1, which run on the base for the layer to be installed with respect to the screed 2 adjacent to the respective outer edge thereof, preferably arranged symmetrically to the longitudinal axis of the road paver 1 and in the illustrated embodiment via a pivotable arm 13 with an integrated in the height controller 10 transducer for the distance covered by the measuring wheel 12 as well as for the angle of the arm 13 to a reference plane for obtaining a height measurement. While the height measurement and the inclination measurement usually lead to an analog signal, the distance measurement usually results in a digital signal.
  • the road paver 1 has an on-board computer 14 with an input keyboard 15, which at the same time has a display field, a microprocessor 16, a data memory 17, a ROM memory 18 for the operating system, an analog input and - Output stage 19 and a digital input and output stage 20.
  • the signals representing the actual values of the height and inclination measurement are fed to the microprocessor 16, as are the signals representing the actual value of the displacement measurement.
  • Setpoints for the height correction or the layer thickness of the layer to be installed are stored in the data memory 17 in relation to the station. These setpoints were determined in advance on the installation section.
  • the microprocessor 16 outputs for the stations, i.e. depending on the distance measurement, the setpoints stored in the data memory 17 before the height controllers 10, so that corresponding height corrections are made in accordance with the unevenness of the base. Between the given stations, which do not have to be equidistant, the microprocessor 16 continuously changes the setpoint for the installation height from one stored value to another, depending on the distance covered, preferably in a linear manner.
  • the set point of the cross slope is continuously measured over the length of the microprocessor 16 Gang distance between the start and end point changed in linear dependence on the length and fed to the inclination controller 11.
  • two measuring wheels 12 are provided at a distance from the central longitudinal axis of the paver 1, both of which are connected via arms 13 to corresponding transducers, so that two height measurements are carried out transversely to the direction of travel of the paver and at a distance from one another.
  • the inclinometer and the inclination controller 11 can be dispensed with if the target values for the height correction or layer thickness are input to the on-board computer 14 in relation to the page.
  • a measuring wheel 12 which can be arranged off-center, can make do with distance measurement, but the height sensors are required for the actuators 8.
  • the measuring wheels 12 can be connected to the extendable parts of the screed 2, so that they are each located in the edge region of the pave.
  • an alarm circuit 21 can be provided for the acoustic and / or visual indication that predetermined setpoints cannot be reached.
  • the actuators 8 are also expediently operable manually, so that the paver can still work if the on-board computer 14 fails.
  • Corresponding markings along the installation path can also be used as sensors.
