Definitions
- the invention relates to a rolling device for soil compaction according to the preamble of patent claim 1.
- slippage is borrowed from the vehicle technology and corresponds to a speed difference between a mantling or rolling surface of the drum bandage and the ground.
- the optimum slip for the compaction of the soil depends on both the operating condition of the compaction roller and the type and nature of the substrate. It is not possible in practice to provide a unique, constant value for optimal slip under different operating conditions on different soils.
- Another problem is the slip behavior in rolling devices with multiple driven roller bandages, since there is always to be expected that at least one of the bandages has too high or too low slip.
- the invention has for its object to provide a rolling device for soil compaction, in which automatically adjusts automatically regardless of the operating state of the device or the condition of the soil, an optimal slip.
- the rolling apparatus has a determination device with which a vertical distance between a surface of the compacted bottom located behind the first roll drum, that is to say just rolled, and a lowest point of the first drum drum, ie the lower vertex of the drum-shaped drum drum, can be determined.
- a speed control device is able to adjust the speed of the roller drum to be controlled.
- the speed control device reduces the Speed if the distance is above a predetermined upper limit. If, accordingly, the distance is negative, so the surface of the compacted soil is at a lower vertical level as the lowest point of the roller bandage, which corresponds to a negative slip, the speed control device can increase the speed if the distance falls below a predetermined lower limit.
- the upper and lower limits are identical and correspond to a slightly positive value which is just above zero. This makes it possible to take into account that the compacted soil springs back after being rolled over by the roll bandage due to its elasticity, so that even if no slippage occurs, the distance must assume a positive value, albeit a low value, because the rebounded surface of the compacted soil at a higher vertical level than the lower vertex of the roll bandage.
- a distance measuring device is provided with which the length of a vertical distance of the surface of the soil and a reference point on the rolling device can be measured.
- the determination device is then able to calculate the vertical distance as the difference between a length value preset by the mechanical structure of the rolling device and already stored in the determination device for a vertical distance between the reference point and the lowest point, ie the lower vertex of the roller bandage and the the distance measuring device measured vertical distance to calculate.
- the slip control according to the invention can be used particularly advantageously in a rolling apparatus in which, in addition to the controlled roll bandage, at least one further rotationally driven roll bandage is present.
- the additional roller bandage then serves, inter alia, for force or torque support for the first, controlled roller bandage.
- controlled roller bandage seen in the direction of travel of the rolling device, the rearmost of all driven roller drums.
- Fig. 1 shows a compaction roll serving as a compactor for soil compaction, which has a first roller drum 1 driven in rotation and a second drum drum 2 likewise driven in rotation.
- roller bandages 1, 2 are driven in a conventional manner by means of a mechanical, hydraulic or electrical system or a combination of these systems, which allow a close-stepped or continuous change in the drive speed.
- a direction of travel of the rolling device is indicated by an arrow 3.
- Fig. 2 shows in an enlarged schematic representation of the first roll drum 1, which rolls over the bottom 4 to be compacted. It can be seen that a surface 5 of the already compacted soil behind the drum bandage 1 is at a higher vertical level than a lowest point 6 of the drum bandage 1. The lowest point 6 is here the lower vertex or a point on the other crest line of the roll bandage 1 viewed.
- the rolling device has a determination device not shown in the figures on, which determines the distance 7 and delivers to a also not shown in the figures speed control device.
- the speed control device is capable of changing the rotational speed of the roller drum 1 as a function of the distance 7.
- the speed control device tries by reducing the speed to reduce the slip.
- Such a case may, for. B. occur when the front roller drum 2 of the rolling device rotates too slowly, so that the rear drum bandage 1 can reach a low horizontal speed over the bottom 4.
- Fig. 3 shows the roll bandage 1 in a state of negative slip, in which it has already come to an accumulation of the bottom 4 before the roll bandage 1.
- the bead still located in front of the roller bandage 1 will be rolled over, which leads to a wavy ground.
- the determining device supplies the negative value of the distance 7 to the speed control device, which tries to increase the slip when falling below a lower limit by increasing the rotational speed of the roller band 1.
- a non-contact measuring system eg. As a distance radar or a laser to install, which determines the vertical distance between the measuring system serving as a reference point and the surface 5 of the compacted bottom 4.
- a mechanical measuring system for. B. with a roll on the surface roll conceivable, the vertical position relative to the chassis of the rolling device is changeable and detectable. Since the other vertical distance from the stationary measuring system to the lowest point 6 of the drum bandage is structurally predetermined by the structure of the rolling apparatus 1, the distance 7 can be calculated in a simple manner from the difference between the measured vertical distance and the predetermined vertical distance.
- slip control according to the invention can without consuming determination of the actual slip - as z. B. in ABS or traction control in motor vehicles is the case - and regardless of the nature and condition of the substrate to be compacted an operating state of the compaction roller can be adjusted, which allows optimal compression of the substrate with high quality of the rolled surface due to minimization of slippage.
- the invention has been described by way of example on a rolling apparatus in which only one of the roll bandages was provided with the corresponding slip control.
- a rolling apparatus in which only one of the roll bandages was provided with the corresponding slip control.
- a direction of travel control of the rolling apparatus could be moreover ensure that even when driving direction changes in each case only the rearmost roller drum undergoes a slip control in the manner described.
- roller bandages it may even be expedient, even with several roller bandages, to provide all with a corresponding slip control and, if appropriate, to connect the individual speed control devices with one another in order to bring about a coordinated behavior of the individual roller bandages.
Description
Die Erfindung betrifft eine Walzvorrichtung zur Bodenverdichtung gemäß dem Oberbegriff von Patentanspruch 1.The invention relates to a rolling device for soil compaction according to the preamble of
Zur Verdichtung von Böden, Straßendecken oder Ähnlichem sind aus z.B.
Neben Art und Beschaffenheit des zu verdichtenden Untergrunds sowie dem Betriebszustand der Verdichtungswalze hat insbesondere der Schlupf der Walzenbandagen einen starken Einfluss auf den Grad der Verdichtung und die Qualität der verdichteten Oberfläche. Der Begriff "Schlupf" ist der Fahrzeugtechnik entlehnt und entspricht einer Geschwindigkeitsdifferenz zwischen einer Mantel- bzw. Walzfläche der Walzenbandage und dem Boden.In addition to the type and nature of the substrate to be compacted and the operating state of the compaction roller, in particular the slippage of the roller drums has a strong influence on the degree of compaction and the quality of the compacted surface. The term "slip" is borrowed from the vehicle technology and corresponds to a speed difference between a mantling or rolling surface of the drum bandage and the ground.
Ein zu niedriger, meist negativer Schlupf bedeutet daher, dass die Umfangsgeschwindigkeit der Walzenbandage geringer ist als die Horizontalgeschwindigkeit, mit der sich die Walzenbandage über dem Boden bewegt. Er tritt insbesondere bei nicht angetriebenen, gezogenen Walzenbandagen auf, da sie sich aufgrund ihrer Massenträgheit und dem Rollwiderstand langsamer drehen als es für ein Abrollen auf dem Boden erforderlich wäre. Als Folge des negativen Schlupfes kann es zu Materialanhäufungen vor der Walze kommen (Bulldozing-Effekt), die je nach Betriebsbedingung in unregelmäßigen Abständen überrollt werden, was zu einer unebenen, welligen Oberfläche führt. Andererseits können bei einem negativen Schlupf hinter der Walzenbandage Querrisse in der Oberfläche aufgrund von Zugspannungen im Boden zurückbleiben, die auch als Walzrisse bezeichnet werden und durch nachträgliches Walzen zwar oberflächlich geschlossen werden können, aber kaum vollständig zu beseitigen sind.Too low, usually negative, slippage therefore means that the peripheral speed of the drum bandage is less than the horizontal speed with which the drum bandage moves above the ground. It occurs in particular in non-driven, drawn roller drums because they rotate slower than it would be necessary for rolling on the ground due to their inertia and the rolling resistance. As a result of the negative slip, material accumulations in front of the roll can occur (bulldozing effect) which, depending on the operating conditions, are rolled over at irregular intervals, which leads to an uneven, wavy surface. On the other hand, in a negative slip behind the drum bandage transverse cracks in the surface due to tensile stresses in the soil remain, which are also referred to as a rolling crack and can be closed superficially by subsequent rolling, but are difficult to eliminate completely.
Ein zu hoher, meist positiver Schlupf, wie er bei angetriebenen Walzenbandagen häufig auftritt, kann einerseits zu Aufschiebungen oder Verwerfungen hinter der Walzenbandage führen. Andererseits besteht durch zu hohen Schlupf je nach Beschaffenheit des Untergrundes die Gefahr eines Wiederauflockerns des verdichteten Bodens hinter der Walzenbandage.Too high, mostly positive slip, as often occurs in driven drum bandages, on the one hand lead to Aufschiebungen or distortions behind the drum bandage. On the other hand, there is too much slip depending on Texture of the substrate the risk of a loosening of the compacted soil behind the drum bandage.
Der für die Verdichtung des Bodens optimale Schlupf hängt sowohl von dem Betriebszustand der Verdichtungswalze als auch von der Art und der Beschaffenheit des Untergrundes ab. Es ist in der Praxis nicht möglich, einen eindeutigen, konstanten Wert für einen optimalen Schlupf unter verschiedenen Betriebsbedingungen auf verschiedenen Böden vorzugeben.The optimum slip for the compaction of the soil depends on both the operating condition of the compaction roller and the type and nature of the substrate. It is not possible in practice to provide a unique, constant value for optimal slip under different operating conditions on different soils.
Weiterhin problematisch wird das Schlupfverhalten bei Walzvorrichtungen mit mehreren angetriebenen Walzenbandagen, da dort immer damit zu rechnen ist, dass wenigstens eine der Bandagen einen zu hohen oder zu niedrigen Schlupf aufweist.Another problem is the slip behavior in rolling devices with multiple driven roller bandages, since there is always to be expected that at least one of the bandages has too high or too low slip.
Der Erfindung liegt die Aufgabe zugrunde, eine Walzvorrichtung zur Bodenverdichtung anzugeben, bei der sich unabhängig vom Betriebszustand der Vorrichtung oder vom Zustand des Bodens stets automatisch ein optimaler Schlupf einstellt.The invention has for its object to provide a rolling device for soil compaction, in which automatically adjusts automatically regardless of the operating state of the device or the condition of the soil, an optimal slip.
Die erfindungsgemäße Lösung ist in Anspruch 1 definiert. Vorteilhafte Weiterentwicklungen der Erfindung sind den abhängigen Ansprüchen zu entnehmen.The solution according to the invention is defined in
Die erfindungsgemäße Walzvorrichtung weist eine Bestimmungseinrichtung auf, mit der sich ein vertikaler Abstand zwischen einer hinter der ersten Walzenbandage liegenden, also soeben überwalzten Oberfläche des verdichteten Bodens und einem tiefsten Punkt der ersten Walzenbandage, also dem unteren Scheitelpunkt der trommelförmigen Walzenbandage, bestimmen lässt. In Abhängigkeit von dem Abstand ist eine Drehzahlregeleinrichtung in der Lage, die Drehzahl der zu regelnden Walzenbandage einzustellen.The rolling apparatus according to the invention has a determination device with which a vertical distance between a surface of the compacted bottom located behind the first roll drum, that is to say just rolled, and a lowest point of the first drum drum, ie the lower vertex of the drum-shaped drum drum, can be determined. Depending on the distance, a speed control device is able to adjust the speed of the roller drum to be controlled.
Unter der Maßgabe, dass der Abstand dann positiv definiert ist, wenn die Oberfläche des verdichteten Bodens auf einem höheren Vertikalniveau liegt als der tiefste Punkt der Walzenbandage, dass also die Walzenbandage hinter sich eine Aufhäufung erzeugt, was einem positiven Schlupf entspricht, reduziert die Drehzahlregeleinrichtung die Drehzahl, wenn der Abstand über einem vorgegebenen oberen Grenzwert liegt. Wenn entsprechend der Abstand negativ ist, also die Oberfläche des verdichteten Bodens auf einem niedrigeren Vertikalniveau liegt als der tiefste Punkt der Walzenbandage, was einem negativen Schlupf entspricht, kann die Drehzahlregeleinrichtung die Drehzahl erhöhen, wenn der Abstand einen vorgegebenen unteren Grenzwert unterschreitet.Assuming that the distance is then defined positively when the surface of the compacted soil is at a higher vertical level than the lowest point of the roll bandage, ie that the roll bandage generates an accumulation behind it, which corresponds to a positive slip, the speed control device reduces the Speed if the distance is above a predetermined upper limit. If, accordingly, the distance is negative, so the surface of the compacted soil is at a lower vertical level as the lowest point of the roller bandage, which corresponds to a negative slip, the speed control device can increase the speed if the distance falls below a predetermined lower limit.
Bei einer besonders vorteilhaften Ausführungsform der Erfindung sind der obere und der untere Grenzwert identisch und entsprechen einem leicht positiven Wert, der knapp über Null liegt. Dadurch lässt sich berücksichtigen, dass der verdichtete Boden aufgrund seiner Elastizität nach dem Überrollen durch die Walzenbandage rückfedert, so dass auch dann, wenn kein Schlupf auftritt, der Abstand einen - wenn auch niedrigen - positiven Wert einnehmen muss, da die rückgefederte Oberfläche des verdichteten Bodens auf einem höheren Vertikalniveau liegt als der untere Scheitelpunkt der Walzenbandage.In a particularly advantageous embodiment of the invention, the upper and lower limits are identical and correspond to a slightly positive value which is just above zero. This makes it possible to take into account that the compacted soil springs back after being rolled over by the roll bandage due to its elasticity, so that even if no slippage occurs, the distance must assume a positive value, albeit a low value, because the rebounded surface of the compacted soil at a higher vertical level than the lower vertex of the roll bandage.
Bei einer weiteren vorteilhaften Ausgestaltung der Erfindung ist eine Streckenmesseinrichtung vorgesehen, mit der sich die Länge einer vertikalen Strecke der Oberfläche des Bodens und einem Referenzpunkt an der Walzvorrichtung messen läßt. Die Bestimmungseinrichtung ist dann in der Lage, den vertikalen Abstand als Differenz zwischen einem durch den mechanischen Aufbau der Walzvorrichtung vorgegebenen, in die Bestimmungseinrichtung bereits eingespeicherten Längenwert für eine vertikale Strecke zwischen dem Referenzpunkt und dem tiefsten Punkt, also dem unteren Scheitelpunkt der Walzenbandage sowie der von der Streckenmesseinrichtung gemessenen vertikalen Strecke zu berechnen.In a further advantageous embodiment of the invention, a distance measuring device is provided with which the length of a vertical distance of the surface of the soil and a reference point on the rolling device can be measured. The determination device is then able to calculate the vertical distance as the difference between a length value preset by the mechanical structure of the rolling device and already stored in the determination device for a vertical distance between the reference point and the lowest point, ie the lower vertex of the roller bandage and the the distance measuring device measured vertical distance to calculate.
Die erfindungsgemäße Schlupfregelung lässt sich besonders vorteilhaft bei einer Walzvorrichtung einsetzen, bei der außer der geregelten Walzenbandage noch wenigstens eine weitere drehend angetriebene Walzenbandage vorhanden ist. Die zusätzliche Walzenbandage dient dann unter anderem zur Kraft- bzw. Drehmomentabstützung für die erste, geregelte Walzenbandage.The slip control according to the invention can be used particularly advantageously in a rolling apparatus in which, in addition to the controlled roll bandage, at least one further rotationally driven roll bandage is present. The additional roller bandage then serves, inter alia, for force or torque support for the first, controlled roller bandage.
Vorteilhafterweise ist die geregelte Walzenbandage, in Fahrtrichtung der Walzvorrichtung gesehen, die hinterste von allen angetriebenen Walzenbandagen.Advantageously, the controlled roller bandage, seen in the direction of travel of the rolling device, the rearmost of all driven roller drums.

Da eine derartige Walzvorrichtung im Prinzip, sei es mit oder ohne einen die Walzenbandagen beaufschlagenden Vibrationsantrieb, bekannt sind, erübrigt sich eine detailliertere Beschreibung.Since such a rolling device is known in principle, be it with or without a roller drums acting vibration drive, known, a more detailed description is unnecessary.
Die Walzenbandagen 1, 2 werden in an sich bekannter Weise mit Hilfe eines mechanischen, hydraulischen oder elektrischen Systems bzw. einer Kombination aus diesen Systemen angetrieben, die eine eng gestufte bzw. kontinuierliche Änderung der Antriebsdrehzahl ermöglichen.The
Eine Fahrtrichtung der Walzvorrichtung ist durch einen Pfeil 3 gekennzeichnet.A direction of travel of the rolling device is indicated by an
Aufgrund der in
Die Walzvorrichtung weist eine in den Figuren nicht dargestellte Bestimmungseinrichtung auf, die den Abstand 7 bestimmt und an eine ebenfalls in den Figuren nicht gezeigte Drehzahlregeleinrichtung liefert. Die Drehzahlregeleinrichtung ist in der Lage, die Drehzahl der Walzenbandage 1 in Abhängigkeit von dem Abstand 7 zu verändern.The rolling device has a determination device not shown in the figures on, which determines the

In
Die Bestimmungseinrichtung liefert den negativen Wert des Abstands 7 an die Drehzahlregeleinrichtung, die bei Unterschreiten eines unteren Grenzwerts durch Erhöhen der Drehzahl der Walzenbandage 1 versucht, den Schlupf zu erhöhen.The determining device supplies the negative value of the
Auch wenn man aufgrund der Theorie annehmen sollte, dass ein Wert für den Abstand 7 von Null dem idealen, schlupffreien Zustand entsprechen dürfte, hat sich in der Praxis herausgestellt, dass ein leicht positiver Wert geringfügig über Null besser geeignet ist, einen schädlichen Schlupf zu vermeiden. Der Grund dafür besteht in der elastischen Eigenschaft des Bodens 4, der nach Überrollen durch die Walzenbandage 1 rückfedert, so dass sich bei schlupffreiem Überrollen immer ein positiver Wert für den Abstand 7 einstellen muss.Although it should be assumed on the theory that a value of zero for the
Zur Bestimmung des Abstands 7 ist es besonders zweckmäßig, am Fahrwerk der Walzvorrichtung ein berührungsloses Messsystem, z. B. ein Abstandsradar oder einen Laser, anzubringen, das die vertikale Strecke zwischen dem als Referenzpunkt dienenden Messsystem und der Oberfläche 5 des verdichteten Bodens 4 bestimmt. Alternativ ist auch ein mechanisches Messsystem, z. B. mit einer auf der Oberfläche abrollenden Rolle denkbar, deren Vertikalstellung relativ zum Fahrwerk der Walzvorrichtung veränder- und erfassbar ist. Da die andere vertikale Strecke von dem ortsfesten Messsystem bis zum tiefsten Punkt 6 der Walzenbandage durch den Aufbau der Walzvorrichtung 1 konstruktiv vorgegeben ist, lässt sich aus der Differenz zwischen der gemessenen vertikalen Strecke und der vorgegebenen vertikalen Strecke in einfacher Weise der Abstand 7 berechnen.To determine the
Der eigentliche Aufbau der Bestimmungseinrichtung und der Drehzahlregeleinrichtung ist mit üblichen Komponenten zu bewerkstelligen. Auf eine detaillierte Beschreibung kann daher verzichtet werden.The actual structure of the determination device and the speed control device can be accomplished with conventional components. A detailed description can therefore be dispensed with.
Mit der erfindungsgemäßen Schlupfregelung kann ohne aufwendige Bestimmung des tatsächlichen Schlupfes - wie dies z. B. bei ABS- oder Traktionsregelungen bei Kraftfahrzeugen der Fall ist - und unabhängig von Art und Beschaffenheit des zu verdichtenden Untergrundes ein Betriebszustand der Verdichtungswalze eingestellt werden, der aufgrund einer Minimierung des Schlupfes eine optimale Verdichtung des Untergrundes bei hoher Qualität der gewalzten Oberfläche ermöglicht.With the slip control according to the invention can without consuming determination of the actual slip - as z. B. in ABS or traction control in motor vehicles is the case - and regardless of the nature and condition of the substrate to be compacted an operating state of the compaction roller can be adjusted, which allows optimal compression of the substrate with high quality of the rolled surface due to minimization of slippage.
Die Erfindung wurde beispielhaft an einer Walzvorrichtung beschrieben, bei der nur eine der Walzenbandagen mit der entsprechenden Schlupfregelung versehen war. Selbstverständlich ist es insbesondere bei größeren Walzenzügen oder bei Walzvorrichtungen, die gleichermaßen vorwärts und rückwärts verfahrbar sind, möglich, dass wenigstens zwei - z. B. die vorderste und die hinterste - Walzenbandagen vorgesehen sind, deren Drehzahl durch die Drehzahlregeleinrichtung zur Vermeidung eines Schlupfes veränderbar ist. Entsprechend müsste dann jeweils der Abstand 7 zwischen der Bodenoberfläche und dem tiefsten Punkt der zugehörigen Walzenbandage in analoger Weise wie oben beschrieben ermittelt werden.The invention has been described by way of example on a rolling apparatus in which only one of the roll bandages was provided with the corresponding slip control. Of course, it is possible, in particular for larger rollers or rolling devices, which are equally movable forwards and backwards, that at least two -. B. the foremost and the rearmost - roll bandages are provided, the speed of which is variable by the speed control device to prevent slippage. Accordingly, in each case the
Eine Fahrtrichtungssteuerung der Walzvorrichtung könnte darüber hinaus dafür sorgen, dass auch bei Fahrtrichtungsänderungen jeweils nur die hinterste Walzenbandage eine Schlupfregelung in der beschriebenen Weise erfährt.A direction of travel control of the rolling apparatus could be moreover ensure that even when driving direction changes in each case only the rearmost roller drum undergoes a slip control in the manner described.
Schließlich kann es in bestimmten Fällen sogar zweckmäßig sein, auch bei mehreren Walzenbandagen alle mit einer entsprechenden Schlupfregelung zu versehen und gegebenenfalls die einzelnen Drehzahlregeleinrichtungen miteinander zu verbinden, um ein abgestimmtes Verhalten der einzelnen Walzenbandagen zu bewirken.Finally, in certain cases it may even be expedient, even with several roller bandages, to provide all with a corresponding slip control and, if appropriate, to connect the individual speed control devices with one another in order to bring about a coordinated behavior of the individual roller bandages.
