Definitions

  • the present invention relates to a road finisher and a method for operating a road finisher.
  • Road surfaces are often not only built in a completely horizontal and flat form, but also have a transverse profile in order to achieve beneficial effects such as improved drainage of rainwater.
  • straight sections with a roof profile i.e. sloping outwards on both sides from a highest line in the middle of the lane, are manufactured. Curves are manufactured with an increasing superelevation from the inner to the outer curve radius.
  • the settings are made by an operator, for example by means of the hydraulic adjustment of the leveling cylinders or manually operable adjusting nuts.
  • a partially automatic control is from the EP 0 849 399 B1 known.
  • a road preparation system is known in which profile data of a subgrade are used when laying a road surface.
  • a method for installing a road surface is known, in which a set of machine parameters is created and stored in advance and implemented during installation.
  • the object of the present invention is to provide a road finisher with an improved control system for automatic cross-section control and an improved method for operating a road finisher.
  • a road finisher comprises a screed, the screed comprising at least one compacting unit.
  • the paver further includes a GNSS receiver, a material conveyor, and an electronic control system, which in turn includes a memory and a data processor.
  • Digital building data in particular a desired height profile of a road surface to be finished, are stored in the memory.
  • the control system is configured to, on the basis of the building data, an actuator system present on the road finisher, in particular leveling cylinders and/or crown profile adjustment and/or Slope adjustment and/or berm adjustment, to automatically control in order to install the paving material with the desired height profile and thus a defined cross-section for the respective local coordinate point of the road finisher determined with the GNSS receiver.
  • Both the position of the entire screed in space and the orientation can be adjusted automatically individual plank parts to each other.
  • the cross slope of the screed can be set automatically to pave a banked curve.
  • a left and a right half of the plank can be automatically set at an angle to one another to produce a crown profile.
  • add-on or extendable elements can also be adjusted automatically; in particular, their inclination transverse to the direction of travel can be adjusted automatically.
  • the actuators can be, for example, hydraulic or electromotive control elements or drives.
  • the transverse profiles can therefore be planned exactly when the digital building data is created and then paved with the road finisher based on precise coordinates. Possible errors by an operator are excluded and he can take care of other operating functions of the road finisher.
  • the control system is preferably configured to automatically control the steering of the road finisher depending on the location. This ensures that the road surface is also installed in the precisely planned position, which is particularly important with a profiled road surface, since the planum and lateral terrain transitions are adapted to this. Due to the GNSS-based position determination of the road finisher, other reference systems such as mechanical, laser-based or visual monitoring by the operator can be omitted, but they can also continue to be used. The automatic control of the steering further relieves the operator.
  • control system is configured to automatically adjust the screed width depending on the location. In this way, changes in the desired width of the road surface are taken into account, with the operator not being additionally required or being able to limit himself to monitoring the automatic settings.
  • the already mentioned and the following automatic functions of the road finisher, based on the digital building data, which are processed by the electronic control system, can allow almost or completely autonomous paving of a road surface.
  • the screed preferably has a transverse inclination sensor, with the control system being configured to automatically control the actuator system on the basis of the data received from the transverse inclination sensor.
  • the screed can have several transverse inclination sensors, at least one of which is expediently attached to each inclination-adjustable screed part. For example, the transverse slope of a right and left half of the base plank, a right and left add-on or extension part and, if necessary, elements for berm adjustment on the add-on or extension parts can be measured. That's how it can be control system automatically make the desired settings with the help of this feedback mechanism.
  • the data from the transverse inclination sensors can indicate the absolute transverse inclination of the respective screed part in space and/or the relative inclination to one or more other screed parts.
  • the road finisher expediently has a sensor for measuring an actual height profile, with the control system being configured to calculate a deviation of the actual height profile from the target height profile and to automatically control the actuators as a function thereof.
  • the automatic paving activity is controlled by machine and the settings can be automatically readjusted in order to achieve the desired result. Not only the machine settings, as mentioned in the previous section, can be monitored, but also the actual paving result, which means that a particularly high paving quality is achieved.
  • control system is configured to automatically adjust the actuators when there is a transition between two transverse profiles.
  • transitions for example from a crown profile on a straight section of road to a curved section, are particularly complex to create manually, since the angling of two halves of the plank to one another must continuously transition into a transverse slope of an otherwise straight plank without causing any bumps.
  • a high road surface quality is particularly important in curve areas.
  • the automatic adjustment takes care of this installation with the highest quality and eliminates setting errors that are possible with manual control.
  • the GNSS position determination of the road finisher ensures the exact positioning of the roadway profiles and their transitions.
  • Transverse inclination sensors for example for a left and right half of the screed, can monitor the current setting of the screed. The operator therefore does not have to manually initiate the transition sequence based on a position determination he has made.
  • control system is configured to compare the actuator settings required to implement the target height profile with their control limits. This ensures that the paver used can pave the desired profiles. It is conceivable to carry out this check using an external data processing system. In both cases, the data from the road paver is stored digitally.
  • control system is configured to compare the adjustment speeds of the actuators required for installing the desired height profile with the possible adjustment speeds. In particular, this enables the incorporation of changes in the to plan the cross-section exactly and to adjust the driving and paving speed of the road finisher accordingly.
  • the road surface is installed in the desired geometry and in the intended position.
  • the position of the GNSS receiver or the receiving antenna on the road finisher can be taken into account, so that the position of the screed is referenced exactly.
  • Two GNSS receivers can also be used for this purpose.
  • a transverse inclination of the screed and/or a screed part is expediently determined by means of one or more transverse inclination sensors.
  • the transverse inclination of each adjustable screed part such as the left or right half of the base screed, extension elements, berm elements, if present, is measured using a separate sensor on the respective element.
  • the data is received and processed by the control system so that an automatic feedback mechanism monitors the exact setting of the bank.
  • the data can also be displayed to an operator.
  • An actual height profile of the paved road surface is preferably determined by means of a sensor. This data can be presented to the operator on a display device, for example. If necessary, the operator can also intervene manually in the production process and make corrections.
  • a difference between the actual height profile and the target height profile is calculated and the actuator system is automatically regulated to minimize the difference.
  • a particularly high production quality is achieved through this feedback mechanism.
  • the actuator system is preferably set automatically during the transition between two transverse profiles.
  • the settings of the screed have to be continuously changed during the transition between two cross profiles until the transition is completely completed. This is extremely difficult and error-prone to do manually. In addition, a second operator is often required. Thanks to the automatic control, paving is always of consistently high quality and the operator is relieved.
  • the digital building data are expediently transmitted from an external data processing system to the memory of the electronic control system by means of a radio or cable connection.
  • all preliminary calculations and data enrichment can be carried out on a PC.
  • the data of the target height profile of the road surface can be linked to the three-dimensional height profile of the subgrade, or can be calculated based on this.
  • the subgrade data may have been previously obtained by a surface scan.
  • the layer thickness of the paving material, the material requirements and other additional data can also be calculated in this way.
  • the external processing of the data is often more practicable, and it may be possible to dispense with the otherwise necessary display and input devices on the road finisher.
  • the actuator settings required for installing the desired height profile are compared with their control limits. This ensures that the road finisher and in particular the screed is suitable for producing the road surface with the desired transverse profiles.
  • the necessary adjustment speeds of the actuators are compared with the possible adjustment speeds before installation begins.
  • the paving speed can be planned and adjusted accordingly.
  • FIG. 1 shows a road finisher 1 with a screed 3 with tamper 5, screed plate 7 and pressure bar 9 for compacting paving material 11, which is deposited in front of the screed 3 by means of a material conveyor 13.
  • the screed 3 produces a road surface 15 with a predetermined transverse profile.
  • a leveling cylinder 17 can also be seen in this side view, which can be controlled, among other things, to set a transverse inclination of the screed 3 .
  • the road finisher 1 also includes a GNSS receiver 25 for determining the current location coordinates, a distance of the actual receiver antenna 27 from the paving screed 3 being able to be taken into account in order to determine the actual position of the screed 3 .
  • the GNSS receiver antenna 27 can also be arranged on the screed 3 .
  • Two GNSS receiver antennas 27 can also be used to exactly determine the position of the screed 3 .
  • An external data processing unit 29 can exchange data with the control system 19 by means of a radio connection 31 or cable connection 33 .
  • At least one axle of the road finisher 1 is equipped with a steering 35, which can also be controlled by the control system 19.
  • figure 2 shows a schematic representation of digital building data 37, which in this example includes a height profile 39 of a planum 41 and a target height profile 43 of the road surface 15 to be finished.
  • the desired height profile 43 is or defines the transverse profile and is shown here in the form of a roof profile.
  • the structure data 37 are each stored for local coordinate points 45 and together with the height data represent a three-dimensional dataset. It goes without saying that transitions between two types of profile are expediently designed to be gradual, ie without abrupt changes.
  • the subgrade data 39 can be obtained, for example, by a surface scan. For this purpose, for example, the subgrade is traveled over with a vehicle, with a surface scanner and a GNSS receiver being arranged on the vehicle and the height data 39 being stored with the respective location coordinates.
  • figure 3 shows a rear view of a road finisher 1 with the screed 3 in a transverse incline for finishing a sloping roadway surface, such as is used for banked curves.
  • the planum 41 already has the desired transverse inclination compared to the horizontal.
  • the road finisher 1 is thus already running on the subgrade 41 at an incline, with the right-left axis of the screed 3 being essentially perpendicular to the rest of the road finisher 1 .
  • transverse inclination sensors 53 can be arranged on the screed 3 or on the respective screed parts 47, 49, 51.
  • figure 4 shows a rear view of a road finisher 1 with the screed 3 in a crown position.
  • a left-hand screed half 47 and a right-hand screed half 49 are adjusted into a mutually inclined position by means of an actuator for adjusting the roof profile 55 .
  • a positive crown profile is shown here, in which the outer ends of the screed 3 are inclined downwards.
  • a negative roof profile is also possible, with the outer ends pointing upwards.
  • a screed 3 is shown without pull-out parts 51, with the pull-out parts 51 being able to be present.
  • sensors 57 for measuring the actual height profile 59 of the paved road surface 15 are shown.
  • the measurement data are compared by the control system 19 with the target height profile 43, and the actuator or actuators for the crown profile adjustment 55 are readjusted accordingly in order to prevent deviations.
  • the geometry of the screed 3 can be adjusted with the actuators 55 for adjusting the crown profile.
  • the transverse inclination of the entire screed 3 and the paving thickness of the road surface 15 can be adjusted by means of the leveling cylinder 17 .
  • figure 5 shows a rear view of a road finisher 1 with the screed 3 in the slope position.
  • the pull-out parts 51 are also inclined towards the halves 47, 49 of the base plank.
  • the settings are made with appropriate actuators for adjusting the slope 61 . For example, more steeply inclined rainwater outlets can be produced at the edges of a roadway.
  • FIG 6 shows a rear view of a road finisher 1 with a screed 3 in berm position.
  • sections 63 of the pull-out parts 51 can be brought into the angled position shown.
  • These berm sections 63 make it possible, for example, to produce a channel for water drainage at the side of the roadway.
  • the berm sections 63 can be automatically controlled by the control system 19 by means of actuators for berm adjustment 67 and can have further transverse inclination sensors 53, so that both the transverse inclination of the main surface 65 of the extension part and the transverse inclination of the berm section 63 can be measured.
  • figure 7 shows a rear view of a road finisher 1 with a screed 3 with extension parts 51, the lower surfaces, including the main surface 65 and, if present, the berm section 63, are adjustable in height. This can be done, for example, by hydraulic or electric drives and in addition to the inclination adjustment.
  • M or W transverse profiles can be set by combinations of the transverse inclinations of the screed parts 47, 49, 51.
