Definitions

  • the present invention relates to a road finisher and a method for operating a road finisher.
  • the EP 2 366 832 A1 describes the installation of a road surface by means of a road finisher, which has a screed with a tamper device, which can be operated transversely to the direction of travel with a variable stroke and variable frequency.
  • the EP 2 325 392 A2 also describes a method for installing a road surface using a road finisher, the stroke of the compaction unit being automatically adjusted as a function of an installation parameter.
  • the object of the present invention is to provide a road finisher with an improved control system and an improved method for operating a road finisher.
  • a road finisher comprises a screed, the screed comprising a tamper.
  • the paver further includes a GNSS (Global Navigation Satellite System) receiver, a material conveyor, and an electronic control system that includes a memory and a data processor.
  • GNSS Global Navigation Satellite System
  • In the memory are digital building data, in particular a target height profile of a road surface to be finished, a target layer thickness of the paving material, a respective degree of pre-compaction dependent on the target layer thickness and, if appropriate, a height profile of a subgrade are stored.
  • the control system is configured to automatically control the compaction performance of the paving screed depending on the target layer thickness in order to pave the paving material for the respective location coordinate point of the road finisher determined with the GNSS receiver with the respective degree of pre-compaction.
  • the target layer thickness is variable, so that an even surface or an even road surface is obtained.
  • the compaction performance of the screed can now be controlled in such a way that where the subgrade has a depression, i.e. a greater layer thickness has to be paved, the material is paved with a higher degree of compaction than in an area where the subgrade is elevated and the layer thickness is therefore smaller.
  • the degrees of compaction are selected in such a way that during subsequent compaction by a roller, all areas are compressed by the same absolute value, i.e. the rolling dimension is the same everywhere, i.e. the areas with a higher layer thickness are compressed and compacted less by the roller than the lower areas layer thickness. This means that the material can be paved with an even surface and this evenness is also retained during post-compacting, since the road surface sinks to the same extent everywhere.
  • a degree of precompression for a respective location coordinate point is preferably stored in the memory of the control system.
  • the values do not have to be calculated first, but the corresponding control signals can be transmitted directly to the components of the road finisher that are relevant for setting the degree of compaction.
  • the road finisher has a sensor for measuring an actual layer thickness of paving material, with the control system being configured to calculate a deviation of the actual layer thickness from the target layer thickness.
  • the paving material can be paved exactly with the desired target layer thickness, i.e. until the deviation between the actual and target layer thickness is equal to zero.
  • Ultrasonic sensors, mechanical tactile sensors, laser sensors or other suitable sensors that work with or without an external reference point can be used for this purpose.
  • the control system is preferably configured to automatically adjust the compaction performance of the screed by controlling the tamper frequency and/or the tamper stroke.
  • the tamper rams the mix under the screed, ensuring there is a sufficient quantity of paving material and compacting it.
  • the screed comprises a screed plate and/or a pressure bar and the control system is configured to automatically adjust the compaction performance of the screed by controlling the vibration frequency and/or amplitude of the screed plate and/or the pressure bar pressure.
  • control system is configured to automatically adjust the compaction performance of the screed by controlling the paving speed.
  • the paving speed determines the duration of the action of the tamper, smoothing plate and pressure bar compaction units and is particularly suitable for adapting the settings to a required working width.
  • the paving material is paved with a known degree of pre-compaction that depends on the layer thickness. This means that the loss of height due to post-compaction with a roller can also be predicted and the paving material can be paved with a layer thickness that is greater by the thickness of the roller. This ensures that the rolling dimension is the same for all spatial coordinate points.
  • one or more target layer thicknesses of the upcoming location coordinate points i.e. those located further ahead in the direction of travel, can also be taken into account to calculate and control the compaction performance.
  • one or more previous values can also be used to ensure a smooth progression of the surface.
  • the installation of the installation material preferably includes the detection of an actual layer thickness by means of a sensor and the calculation of a difference between the actual layer thickness and the target layer thickness and the road finisher being automatically controlled to minimize the difference.
  • the essential paving parameters namely the layer thickness and the degree of pre-compaction
  • the paver operator can devote more attention to other paving tasks to be completed.
  • the current values of the paving parameters, in particular layer thickness and degree of pre-compaction shown on a display so that an operator can read them and also intervene in the automatic control and change the parameters. Since the course, i.e.
  • the electronic control system automatically adjusts the compaction performance of the screed by controlling the tamper frequency and/or the tamper stroke.
  • the tamper can be seen as the first step in screed compaction. On the one hand, it influences the amount of paving material that gets under the screed. On the other hand, the paving material is pre-compacted by it.
  • control system automatically adjusts the compaction performance of the screed by controlling the vibration frequency and/or amplitude of the screed plate and/or the pressure on the pressure bars. This means that high degrees of compaction can also be achieved with greater layer thicknesses.
  • control system automatically adjusts the compaction performance of the screed by controlling the paving speed.
  • the paving speed can be adjusted as a function of the desired layer thickness.
  • the digital building data which include the height profile of the planum, are transferred from an external data processing system at the beginning of the method transferred to the memory of the electronic control system via radio or cable connection.
  • the external data processing system can be, for example, a laptop, tablet, mobile phone, stationary personal computer, server or the like, and radio transmission can take place using RFID, Bluetooth, WLAN, a mobile phone connection or the like.
  • the subgrade data which was previously determined by means of a surface scan with an independent vehicle, for example, can be analyzed, processed and supplemented with dependent, calculated data. This can take place, for example, at a central site monitoring site and the data can then be transmitted to the road finisher on site.
  • the respective compaction performance is calculated by means of an external data processing system as a function of the determined target layer thickness and/or the respective compaction performance is assigned to a location coordinate point as a function of the target layer thickness and the data are then transferred to the memory of the electronic control system.
  • the compression performance and thus the degree of pre-compression can always be calculated or taken from a table-like data record.
  • the calculation using an external system has the advantage that the necessary devices can be easily kept and the data can also be displayed, analyzed and processed using the appropriate EDP devices.
  • the respective compaction performance is calculated by means of the electronic control system as a function of the determined desired layer thickness and/or the respective compaction performance is assigned to a location coordinate point as a function of the desired layer thickness.
  • figure 1 shows a schematic side view of a road finisher 1, with a material bunker 3 with paving material 5 being shown in a sectional view in a lower area, and the paving material 5 being conveyed by means of a material conveyor 7 through a tunnel 9 to the rear in front of a paving screed 11 and there by a auger 12 is evenly distributed.
  • the road finisher 1 also includes a GNSS receiver 13 which is connected to an electronic control system 15 .
  • the electronic control system 15 includes a memory 17 and a data processor 19.
  • the screed 11 includes a tamper 21, a smoothing plate 23, and a pressure bar 25, it also being possible for several of these components to be present.
  • the paving material 5 is pre-compacted by means of the paving screed 11 and paved with a layer thickness d B , which in ideal operation corresponds to the target layer thickness ds, on a planum 27 as a road surface 28, with the target layer thickness ds being a rolling dimension s higher than the desired one Final layer thickness d E , which is present after post-compaction by a roller.
  • a sensor 29, which can be attached to the screed 11 or the chassis of the road finisher 1, is used to measure the actual layer thickness di of the paving material 5.
  • the sensor 29 can also be attached in such a way that it still measures the actual layer thickness di of paving measures, and so the screed 11 can be readjusted.
  • An external data processing system 31 for example a laptop, can be used to send and receive building data, by means of a radio connection via antennas 33 on the road finisher 1 and on the data processing system 31, in which case the antennas 33 can also be suitable for receiving satellite signals for position determination, or via a cable connection 35, may be provided.
  • figure 2 shows a three-dimensional view of digital building data 37.
  • the planum 27 has a height profile 39 which includes height data for individual location coordinate points 41.
  • This height profile 39 can have been obtained by means of a previous surface scan using an external vehicle.
  • a corresponding scanning device is attached to the road finisher 1 itself and the surface scan takes place for a part of the subgrade 27 that is further forward in the direction of travel, while paving material 5 is already in place in a rear part, based on the digital building data 37 already obtained , is installed.
  • the data of the height profile 39 of the planum 27 is enriched with the data of a target height profile 43 of the road surface 28 to be finished.
  • the different desired layer thicknesses ds for the respective location coordinate points 41 are thus stored in accordance with the elevations and depressions of the height profile 39 of the planum 27 .
  • the number of data points or location coordinate points 41 for which subgrade and road surface data are stored can vary depending on the technical specifications for data acquisition and processing, for example the accuracy of the GNSS, and thus represents a form of "resolution". It is also conceivable that the processing of the digital building data 37 includes algorithms that distinguish areas with frequent and/or severe unevenness in the subgrade 27 from areas with few changes and proportionally adjust the number of data points, which on the one hand maintains a high information density and on the other hand the data volume is reduced.
  • the position of the data points 41 in the grid can be influenced by a sensor position.
  • the digital building data 37 includes further data, which was calculated in particular on the basis of the measured data, such as the height profile 39 of the planum 27, such as a desired degree of compaction per location coordinate point 41.
