Abstract
Description
Die Erfindung bezieht sich auf ein Verfahren zum Einbau von Schichten eines Straßenbaumaterials durch einen fahrbaren, mit einem Verdichtungsaggregat versehenen Straßenfertiger der im Oberbegriff von Anspruch 1 erläuterten Art. Die Erfindung bezieht sich weiterhin auf einen dafür geeigneten Straßenfertiger der im Oberbegriff von Anspruch 5 erläuterten Art.The invention relates to a method for the installation of layers of road construction material by a mobile road paver provided with a compaction unit of the type explained in the preamble of
Ein Straßenfertiger, der mit einem stampfend angetriebenen Verdichtungsaggregat zum Verdichten des seiner Einbaubohle vorgelegten bituminösen Mischgutes arbeitet, ist der DE-A-31 14 049 bekannt. Der Tamper oder die Stampferleiste des bekannten Straßenfertigers wird durch eine Exzenterwelle in Vertikalrichtung bewegt. Die Exzenterwelle wird, bevorzugt durch einen hydrostatischen Antrieb, mit einer vorbestimmten Drehzahl angetrieben, wobei die Drehzahl die Frequenz der Vertikalbewegungen und die Exzentrizität den Tamperhub bestimmt. Die Drehzanl der Exzenterwelle und somit die Arbeitsfrequenz des Tampers ist so eingestellt, daß sie bei der normalen Einbaugeschwindigkeit d. h. der durchschnittlichen Fahrgeschwindigkeit, des Straßenfertigers entsprechend des verwendeten Straßenbaumaterials und der gewünschten Schichtstärke, die gewünschten Verdichtungsergebnisse liefert. Es ergibt sich jedoch bisher immer das Problem, daß insbesondere beim Anfahren des Straßenfertigers Anfahrbuckel bzw. -vertiefungen entstehen.DE-A-31 14 049 discloses a road paver which works with a ramming driven compacting unit for compacting the bituminous mix presented to its screed. The tamper or the tamper bar of the known paver is moved in the vertical direction by an eccentric shaft. The eccentric shaft is driven, preferably by a hydrostatic drive, at a predetermined speed, the speed determining the frequency of the vertical movements and the eccentricity determining the tamper stroke. The speed of the eccentric shaft and thus the working frequency of the tamper is set so that it delivers the desired compaction results at the normal paving speed, ie the average driving speed, of the paver according to the road construction material used and the desired layer thickness. So far, however, there has always been the problem that, especially when starting up the road paver, bumps or dents are formed.
Der Erfindung liegt somit die Aufgabe zugrunde, ein Verfahren zum Einbau von Schichten eines Straßenhaumaterials durch einen fahrbaren, mit einem Verdichtungsaggregat versehenen Straßenfertiger und einen dafür geeigneten Straßenfertiger aufzuzeigen, mit dem Unregelmäßigkeiten in der einzubauenden Schicht beim Anfahren vermieden werden.The invention is therefore based on the object of demonstrating a method for the installation of layers of a road building material by a mobile road paver provided with a compaction unit and a road paver suitable for this purpose, with which irregularities in the layer to be built in when starting are avoided.
Die Aufgabe wird bei einem Verfahren durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.The object is achieved in a method by the characterizing features of
Es konnte festgestellt werden, daß Unregelmäßigkeiten in der Einbauschicht beim Anfahren auf eine nicht mit der Einbaugeschwindigkeit abgestimmte Frequenz des Antriebes des Verdichtungsaggregates zurückzuführen sind. Durch die erfindungsgemäße Kopplung der Verdichtungsfrequenz an die tatsächliche Einbaugeschwindigkeit wird dieser Nachteil behoben. Darüberhinaus werden auch Unregelmäßigkeiten in der einzubauenden Schicht bei Schwankungen der Einbaugeschwindigkeit während des Einbaus oder beim Anhalten des Fertigers vermieden.It was found that irregularities in the paving layer when starting up can be attributed to a frequency of the drive of the compression unit that is not coordinated with the paving speed. This disadvantage is eliminated by coupling the compression frequency according to the invention to the actual installation speed. In addition, irregularities in the layer to be installed in the event of fluctuations in the installation speed during installation or when the paver is stopped are also avoided.

Die Maßnahme nach Anspruch 6 erhöht die Sicherheit der Steuerung.The measure according to claim 6 increases the security of the control.

Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der Zeichnungen näher erläutert. Es zeigen:
-
Figur 1 die Seitenansicht eines Straßenfertigers in schematischer Darstellung, -
Figur 2 die schematische Darstellung eines Tamperantriebs, -
Figur 3 einen schematischen Schaltplan der Steuerung des Tamperantriebs, und - Figur 4 eine bevorzugte Sollwertkurve
- FIG. 1 shows a schematic representation of the side view of a paver,
- FIG. 2 shows the schematic illustration of a tamper drive,
- Figure 3 is a schematic circuit diagram of the control of the tamper drive, and
- Figure 4 shows a preferred setpoint curve
Aus Figur 1 ist ein Straßenfertiger 1 ersichtlich, der über Räder 2 (oder ein Rampenfahrwerk) in Richtung des Pfeiles F auf einem Untergrund 3 fahrbar angetrieben ist. Der Straßenfertiger 1 schleppt eine Einbaubohle 4 nach, die über Holme 5 und Hubzylinder 6 an seinem Rahmen angelenkt ist. Zwischen der Einbohle 4 und dem Rahmen des Straßenfertigers 1 befindet sich eine quer zur Fahrrichtung F verlaufende Förderschnecke 7, durch die der Einbaubohle 4 Straßenbaumaterial 8, im vorliegenden Falle bituminöses Mischgut zum Herstellen einer Straßendeckenschicht 9, vorgelegt wird. An der in Fahrrichtung F vorderen Seite der Einbaubohle 4 ist ein Abstreifblech 10 vorgesehen, durch das das Mischgut 8 verteilt wird. Hinter dem Abstreifblech 10 befindet sich eine vertikal bewegbare Stampferleiste oder ein Tamper 11, der in seiner Vertikalbewegung an einer dahinterliegenden ersten Verdichtungsbohle 12 geführt wird. Der ersten Verdichtungsbohle 12 folgt eine zweite Verdichtungsbohle 13, wobei zwischen beiden Verdichtungsbohlen 12, 13 eine weitere Verdichtungsleiste angeordnet sein kann. Die beiden Verdichtungsbohlen 12, 13 sind jeweils an ihrer Unterseite mit einem Glättblech 12a bzw. 13a versehen, die die vom Tamper bzw. der Verdichtungsleiste 14 bearbeitete Oberfläche der Schicht 9 glätten.1 shows a
Wie Figur 2 zeigt, weist der Tamper 11 eine vordere schräge Druckfläche 15 auf und ist in Lagern 16 an der Vorderseite der ersten Verdichtungsbohle 12 geführt. Um den Tamper 11 auf und ab zu bewegen, steht dieser über pleuelartige Antriebsglieder 17 mit einer Welle 18 eines Exzenterantriebes in Arbeitsverbindung, die in stationären Lagern 19 gelagert ist und durch einen in Figur 3 dargestellten, hydrostatischen Antrieb 20 in Bewegung setzbar ist.As FIG. 2 shows, the
Wie Figur 3 zeigt, enthält der hydrostatische Antrieb 20 in üblicher Weise eine Pumpe 21, ein Hydraulikventil 22 als Schalter für den Tamper und einen Motor 23. Mit dem Motor 23 ist die Antriebswelle 18 des Exzenterantriebes für den Tamper 11 verbunden.As FIG. 3 shows, the
Zum Regeln der Drehzahl der Antriebswelle 18 des Exzenterantriebes ist ein Regelkreis mit einem Regler 24 vorgesehen, der mit einem Start/Stop-Schalter 25 (Fahrhauptschalter) verbunden ist. Der Regler 24 erhält Signale von einem Istwertgeber 26, der die tatsächliche Drehzahl der Antriebswelle 18 und gegebenenfalls den Hub des Tampers 11 feststellt. Der Istwergeber 26 ist bevorzugt ein kontaktloser Wegsensor zum Feststellen der Drehzahl und der Amplitude. Der Regler 24 enthält weitere Signale von einem Istwertgeber 27, der mit einem Fahrgetriebe 28 an der Antriebswelle der Räder 2 verbunden ist und die tatsächliche Fahrgeschwindigkeit des Straßenfertigers 1 feststellt. An einem Sollwertgeber 29 wird der aus der Tabelle ersichtliche Bereich der Tamperdrehzahl je nach Einbaustärke, Schichtart und erforderliche Verdichtung vorgegeben.
Dem Regler 24 wird weiterhin eine empirisch ermittelte Sollwertkurve für die optimal wirksame Tamperdrehzahl in Abhängigkeit von der Fahrgeschwindigkeit des Fertigers vorgegeben. Auf der Basis dieser Vorgabe ermittelt der Regler 24 die optimale Drehzahl des Tamperantriebs für die festgestellte Fahrgeschwindigkeit, vergleicht die ermittelte, optimale Drehzahl mit dem vom Istwertgeber 26 ermittelten Istwert der Drehzahl und betätigt bei Abweichungen des ermittelten Drehzahl-Istwertes vom optimalen Sollwert einen elektrisch einstellbaren Stromregler 30, durch den die Tamperdrehzahl am Tampermotor 23 so weit verstellt wird, daß der Istwert der Tamperdrehzahl dem vorbestimmten Sollwert entspricht.The
Figur 4 zeigt eine bevorzugte Sollwertkurve mit einem genau proportionalen Anstieg der Tamperdrehzahl (strichpunktierte Linie) mit der Einbaufahrgeschwindigkeit (durchgezogene Linie). Durch den Sollwertgeber 29 werden 100 Prozent der Tamperdrehzahl bei 100 Prozent der Einbaufahrgeschwindigkeit vorgegeben. Der Verlauf der Tamperdrehzahl bis zum Erreichen der vollen (100 Prozent) Fahrgeschwindigkeit wird dann nach dieser Sollwertkurve geregelt.FIG. 4 shows a preferred setpoint curve with an exactly proportional increase in the tamper speed (dash-dotted line) with the installation driving speed (solid line). The
In Abwandlung des beschriebenen und gezeichneten Ausführungsbeispiels kann die Einbaugeschwindigkeit über andere Parameter als die Fahrgeschwindigkeit oder die Fahrgeschwindigkeit an anderer Stelle als am Getriebe festgestellt werden. Das erfindungsgemäße Verfahren ist weiterhin auch für andere Straßenfertiger mit anderen Verdichtungsaggregaten und für andere Exzenterantriebe einsetzbar. Die Sollwertkurve der Tamperdrehzahl muß nicht unbedingt mit dem Verlauf des Anstiegs der Einbaufahrgeschwindigkeit zusammenfallen; es kann vielmehr durch veränderte Parameter der Einbauschicht oder dergleichen eine abweichende Sollwertkurve notwendig werden.In a modification of the exemplary embodiment described and drawn, the installation speed can be determined via parameters other than the driving speed or the driving speed at a location other than on the transmission. The method according to the invention can also be used for other road pavers with other compaction units and for other eccentric drives. The setpoint curve of the tamper speed does not necessarily have to coincide with the course of the increase in the installation driving speed; it can rather be changed by changing the parameters A different setpoint curve may be necessary.
