Description

Die vorliegende Erfindung betrifft ein Reinigungsfahrzeug zum Reinigen einer Oberfläche mit wenigstens einem Saugschacht zum Aufsaugen von Verunreinigungen.The present invention relates to a cleaning vehicle for cleaning a surface with at least one suction shaft for absorbing impurities.

Aus der DE 40 01 088 C2 ist ein Reinigungsfahrzeug bekannt, das einen zwischen den Vorderrädern und den Hinterrädern des Fahrzeuges angeordneten Besen aufweist, der Kehricht und ähnliche Verunreinigungen zusammenkehrt. Nachlaufend zu dem Besen ist ein Saugschacht angeordnet, mittels dessen der Kehricht in einen Behälter des Fahrzeuges aufgesaugt wird. Der Saugschaft ist fest mit einem Laufrad verbunden und ist mit diesem in vertikaler Richtung schwenkbar gelagert, so dass Unebenheiten der Straße ausgeglichen werden können.From the DE 40 01 088 C2 For example, a cleaning vehicle is known that has a broom disposed between the front wheels and the rear wheels of the vehicle that sweeps rubbish and similar contaminants. Trailing to the broom, a suction shaft is arranged, by means of which the refuse is absorbed in a container of the vehicle. The Saugschaft is firmly connected to an impeller and is pivotally mounted with this in the vertical direction, so that unevenness of the road can be compensated.

Aus der DE 199 35 887 C1 ist ein Reinigungsfahrzeug bekannt, bei dem der Saugschacht mittels einer Vorrichtung heb- und senkbar ist und das zumindest einen Sensor zum Erfassen des Profils der in Fahrtrichtung vor dem Saugschacht liegenden Oberfläche aufweist. Mittels einer Steuervorrichtung wird der Saugschacht in Abhängigkeit von dem durch den Sensor erfaßten Oberflächenprofil angehoben bzw. gesenkt.From the DE 199 35 887 C1 a cleaning vehicle is known in which the suction shaft can be raised and lowered by means of a device and which has at least one sensor for detecting the profile of the lying in front of the suction shaft in the direction of travel surface. By means of a control device, the suction shaft is raised or lowered as a function of the surface profile detected by the sensor.

Des weiteren sind aus dem Stand der Technik Reinigungsfahrzeuge bekannt, bei denen der Saugschacht und eine diesem nachlaufende Kehrwalze in einem Wagen angeordnet sind, der vom Fahrzeug gezogen wird und auf der zu reinigenden Oberfläche rollt. Die Größe des Saugspaltes, das heißt der Abstand vom unteren Saugschachtende zu der zu reinigenden Oberfläche sowie der Anpreßdruck der Nachlaufwalze werden in Relation zu diesem Wagen beispielsweise mechanisch eingestellt.Furthermore, from the prior art cleaning vehicles are known in which the suction shaft and this trailing sweeping roller are arranged in a car, which is pulled by the vehicle and rolls on the surface to be cleaned. The size of the suction gap, that is, the distance from the lower Saugschachtende to the surface to be cleaned and the contact pressure of the follower roller are mechanically adjusted in relation to this car, for example.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Fahrzeug zum Reinigen von Oberflächen dahingehend weiterzubilden, dass auf vergleichsweise einfache Art und Weise die Größe des Saugspaltes sowie der Anpreßdruck eines im Reinigungsbetrieb relativ zu der zu reinigenden Oberfläche bewegten Bauteils einstellbar ist.The object of the present invention is to further develop a vehicle for cleaning surfaces such that the size of the suction gap and the contact pressure of a component moving in cleaning operation relative to the surface to be cleaned are adjustable in a comparatively simple manner.

Diese Aufgabe wird durch ein Fahrzeug mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a vehicle having the features of claim 1.

Danach ist vorgesehen, dass ein mit dem Saugschacht unmittelbar oder mittelbar in Verbindung stehendes Bauteil, wie beispielsweise eine Kehrwalze vorgesehen ist, das im Reinigungsbetrieb des Fahrzeuges in Kontakt zu der Oberfläche steht. Das Fahrzeug weist des weiteren eine Lagerung auf, mittels derer die Einheit aus Saugschacht und Bauteil schwimmend derart gelagert ist, dass durch die Lagerung zumindest ein Teil der Gewichtskraft des Saugschachtes und des Bauteils aufgenommen wird. Die Lagerung ist somit derart ausgeführt, dass die Gewichtskraft der Einheit aus Saugschacht und Bauteil zumindest teilweise von der schwimmende Lagerung aufgenommen wird, dass also die schwimmende Lagerung eine der Gewichtskraft entgegengerichtete Kraft ausübt.Thereafter, it is provided that a directly or indirectly related to the suction shaft component, such as a sweeping roller is provided, which is in the cleaning operation of the vehicle in contact with the surface. The vehicle further comprises a bearing, by means of which the unit is mounted floating from the suction shaft and component such that at least part of the weight of the suction shaft and the component is received by the storage. The storage is thus carried out such that the weight of the unit of suction shaft and component is at least partially taken up by the floating bearing, so that the floating bearing exerts a force opposing the weight force.

Durch die schwimmende Lagerung ist eine Einstellung der Anpreßkraft des Bauteils auf die Oberfläche sowie die gewünschte Höheneinstellung der Einheit aus Saugschacht und Bauteil möglich. Die schwimmende Lagerung erlaubt darüber hinaus eine hinreichend große vertikale Bewegung der Einheit aus Saugschacht und Walze zum Ausgleich von Fahrbahnunebenheiten.Due to the floating bearing adjustment of the contact pressure of the component on the surface and the desired height adjustment of the unit from the suction shaft and component is possible. The floating storage allows beyond a sufficiently large vertical movement of the unit from the suction shaft and roller to compensate for road bumps.

In einer bevorzugten Ausgestaltung der Erfindung ist eine Hub- und/oder Senkeinrichtung vorgesehen, mittels derer die Einheit aus Bauteil und Saugschacht anhebbar und/oder absenkbar ist.In a preferred embodiment of the invention, a lifting and / or lowering device is provided, by means of which the unit of component and suction shaft can be raised and / or lowered.

In einer bevorzugten Ausgestaltung der Erfindung handelt es sich bei der Hub- und/oder Senkeinrichtung um eine pneumatisch oder hydraulisch betriebene Einrichtung.In a preferred embodiment of the invention, the lifting and / or lowering device is a pneumatically or hydraulically operated device.

In einer bevorzugten Ausgestaltung der Erfindung ist vorgesehen, dass die eingangs genannte schwimmende Lagerung durch die Hub- und/oder Senkeinrichtung gebildet wird oder zumindest deren Bestandteil bildet.In a preferred embodiment of the invention it is provided that the above-mentioned floating storage is formed by the lifting and / or lowering device or at least forms part of it.

Denkbar ist es somit beispielsweise, dass im Reinigungseinsatz die Einheit aus Saugschacht und Walze bzw. Bauelement beispielsweise pneumatisch abgesenkt wird. Die erforderliche Höheneinstellung dieser Einheit erfolgt nun durch eine Schwimmschaltung direkt in der beispielsweise pneumatischen Hub- und/oder Senkeinrichtung.It is thus conceivable, for example, that in the cleaning insert, the unit from the suction shaft and roller or component, for example, is lowered pneumatically. The required height adjustment of this unit is now done by a float circuit directly in the example pneumatic lifting and / or lowering device.

Bei dem Bauteil kann es sich um ein relativ zur Oberfläche rotierendes oder auf der Oberfläche gleitendes Bauteil handeln.The component may be a component rotating relative to the surface or sliding on the surface.

In Betracht kommt beispielsweise wenigstens eine Kehrwalze, ein Kehrbesen, eine Rolle, eine Walze, eine Kufe oder eine Schleifplatte oder auch mehrere dieser Elemente oder auch Kombinationen dieser Elemente. Sofern es sich um ein rotierendes Bauteil handelt, kann vorgesehen sein, dass dies zur Fahrtrichtung gegenläufig rotiert..For example, at least one sweeping roller, one broom, one roller, one roller, one blade or a sanding plate, or even several of these elements or even combinations of these elements may be considered. If it is a rotating component, it can be provided that this rotates counter to the direction of travel.

In weiterer Ausgestaltung der Erfindung ist vorgesehen, dass der Saugschacht und/oder das Bauteil nicht in einem Wagen angeordnet sind, der im Fahrbetrieb des Fahrzeuges auf der Oberfläche rollt. Dadurch ergibt sich im Vergleich zum Stand der Technik eine wesentliche Vereinfachung eines bekannten Fahrzeuges, wobei erfindungsgemäß jedoch die Möglichkeit erhalten bleibt, sowohl den Anpreßdruck des Bauteils als auch die Größe des Saugspaltes einzustellen.In a further embodiment of the invention, it is provided that the suction shaft and / or the component are not arranged in a carriage, while driving of the vehicle on the surface rolls. This results in comparison to the prior art, a significant simplification of a known vehicle, according to the invention, however, the possibility is maintained to adjust both the contact pressure of the component and the size of the suction gap.

Vorzugsweise ist das Bauteil, beispielsweise die Kehrwalze, derart ausgeführt, dass es relativ zu dem Saugschacht bewegbar ist. Dabei ist vorzugsweise vorgesehen, dass das Bauteil ausschließlich oder zumindest auch in vertikaler Richtung bzw. senkrecht zu der zu reinigenden Oberfläche bewegbar ist. Dadurch kann eine Veränderung oder Justierung der Größe des Saugspaltes sowie des Anpressdruckes erfolgen.Preferably, the component, for example the sweeping roller, is designed such that it can be moved relative to the suction shaft. It is preferably provided that the component is movable exclusively or at least also in the vertical direction or perpendicular to the surface to be cleaned. This can be done a change or adjustment of the size of the suction gap and the contact pressure.

Das Bauteil kann relativ zu dem Saugschacht schwenkbar angeordnet sein.The component may be arranged pivotable relative to the suction shaft.

Ebenso ist es denkbar, dass das Bauteil relativ zu dem Saugschacht verschieblich angeordnet ist.It is also conceivable that the component is arranged displaceably relative to the suction shaft.

In weiterer Ausgestaltung der Erfindung ist eine Verstelleinheit vorgesehen, mittels derer das Bauteil zum Zwecke der Verstellung der Relativposition zwischen Bauteil und Saugschacht bewegbar ist. Die Verstelleinheit kann manuell zu betätigen sein oder auch mit einer Antriebseinheit in Verbindung stehen, mittels derer eine Betätigung der Verstelleinheit vorgenommen wird.In a further embodiment of the invention, an adjusting unit is provided, by means of which the component for the purpose of adjusting the relative position between the component and the suction shaft is movable. The adjusting unit can be operated manually or also be in communication with a drive unit, by means of which an actuation of the adjusting unit is performed.

Bei der Verstelleinheit kann es sich beispielsweise um eine mechanische Höhenverstellung oder auch um eine motorisch, pneumatisch oder hydraulisch angetriebene Verstelleinheit handeln, mittels derer das Bauteil relativ zu dem Saugschacht bewegbar ist und damit die Größe des Saugspaltes bzw. der Anpressdruck einstellbar oder nachjustierbar ist.The adjustment unit may be, for example, a mechanical height adjustment or a motor, pneumatically or hydraulically driven adjustment unit, by means of which the component is movable relative to the suction shaft and thus the size of the suction gap or the contact pressure is adjustable or readjustable.

In weiterer Ausgestaltung der Erfindung ist ein Träger vorgesehen, an dem der Saugschacht und/oder das Bauteil angeordnet ist, wobei die Lagerung und/oder die Verstelleinheit mit diesem Träger in Verbindung stehen.In a further embodiment of the invention, a carrier is provided on which the suction shaft and / or the component is arranged, wherein the storage and / or the adjustment unit are in communication with this carrier.

In bevorzugter Ausgestaltung der Erfindung ist vorgesehen, dass es sich bei dem Bauteil um ein Bauteil handelt, das im Betrieb des Fahrzeuges dem Saugschacht nachläuft.In a preferred embodiment of the invention, it is provided that the component is a component which runs after the suction shaft during operation of the vehicle.

Weitere Einzelheiten und Vorteile werden anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert. Die einzige Figur zeigt eine Detaildarstellung der Anordnung von Saugschacht und einer nachlaufenden Kehrwalze gemäß der vorliegenden Erfindung.Further details and advantages will be explained with reference to an embodiment shown in the drawing. The single figure shows a detailed representation of the arrangement of suction shaft and a trailing sweeping roller according to the present invention.

Die in der Figur dargestellte Einheit aus Saugschacht 1 und Kehrwalze 2 befindet sich in einem Bereich zwischen den Vorderrädern und Hinterrädern eines Reinigungsfahrzeuges.
Die in der Figur dargestellte Einheit aus Saugschacht 1 und Kehrwalze 2 ist an einem Reinigungsfahrzeug befestigt.The unit shown in the figure of suction shaft 1 and brush 2 is located in an area between the front wheels and rear wheels of a cleaning vehicle.
The unit shown in the figure from the suction shaft 1 and brush 2 is attached to a cleaning vehicle.

Die nachlaufende und zur Fahrtrichtung gegenläufig rotierende Kehrwalze 2 ist über eine Halterung schwenkbar an dem Saugschacht 1 angeordnet. Der Saugschacht 1 ist seinerseits an einem Träger 7 angeordnet, wie dies aus der Figur hervorgeht.The trailing and counter to the direction of rotation counter-rotating sweeping roller 2 is pivotally mounted on a support on the suction chute 1. The suction shaft 1 is in turn arranged on a carrier 7, as can be seen from the figure.

Mit dem Bezugszeichen 6 ist eine mechanisch einstellbare Verstelleinheit gekennzeichnet, mittels derer die Position der Kehrwalze 2 relativ zu dem Träger 7 und damit auch zu dem Saugschacht 1 veränderbar ist. Durch die Verstelleinheit 6 ist es somit eine Höhenverstellung der Achse der Nachlaufwalze 2 in Bezug auf die Saugschachtunterkante möglich.The reference numeral 6 denotes a mechanically adjustable adjustment unit, by means of which the position of the sweeping roller 2 relative to the carrier 7 and thus also to the suction chute 1 is variable. By adjusting 6, it is thus possible to adjust the height of the axis of the follower roller 2 with respect to the Saugschachtunterkante.

Wie dies aus der Figur ersichtlich ist, ist die Verstelleinheit 6 einerseits an der Kehrwalze 2 bzw. deren Halterung und andererseits an dem Träger 7 schwenkbar angeordnet. Wird der Abstand der beiden Anlenkungspunkte zueinander durch Verstellen der Verstelleinheit 6 vergrößert, führt dies dazu, dass die Kehrwalze 2 gemäß der Figur nach unten verschwenkt wird, was zu einer Vergrößerung des Saugspaltes und/oder des Anpressdruckes führt. Wird der Abstand zwischen den beiden Anlenkungspunkten mittels der Verstelleinheit 6 verringert, führt dies zu einem Verschwenken der Kehrwalze 2 nach oben, wodurch es zu einer Verkleinerung des Saugspaltes 4 und/oder des Anpressdruckes kommt.As can be seen from the figure, the adjusting unit 6 is arranged pivotably on the one hand on the sweeping roller 2 or its holder and on the other hand on the carrier 7. If the distance of the two articulation points from one another is increased by adjusting the adjusting unit 6, this leads to the sweeping roller 2 being pivoted downwards according to the figure, which leads to an enlargement of the suction gap and / or the contact pressure leads. If the distance between the two articulation points is reduced by means of the adjusting unit 6, this leads to a pivoting of the sweeping roller 2 upwards, which leads to a reduction of the suction gap 4 and / or the contact pressure.

Lässt sich allein durch die Lagerung 5 bzw. durch die Hub- und Senkeinrichtung 5 nicht die gewünschte Kombination aus Anpressdruck des Bauteils und Größe des Saugspaltes erreichen, kann durch die optional vorgesehene Verstellmöglichkeit bzw. Verstelleinheit 6 eine Veränderung der Position des Bauteils relativ zum Saugschacht und damit eine Einflussnahme auf den Anpressdruck und/oder auf den Saugspalt genommen werden.If the desired combination of contact pressure of the component and size of the suction gap can not be achieved solely by the bearing 5 or by the lifting and lowering device 5, the optionally provided adjustment or adjustment unit 6 can change the position of the component relative to the suction shaft and so that an influence on the contact pressure and / or on the suction gap are taken.

Mit dem Bezugszeichen 5 ist eine Hub- und Senkeinrichtung gekennzeichnet, die pneumatisch betrieben wird und mittels derer die gesamte Einheit aus Saugschacht 1 und Walze 2 insgesamt nach oben oder nach unten bewegbar ist. Mittels dieser Lagerung bzw. Schwimmschaltung 5 ist die erforderliche Höhenregulierung der Einheit aus Saugschacht 1 und Walze 2 möglich. Anstelle einer pneumatischen Hub- bzw. Senkvorrichtung kann auch selbstverständlich eine anders ausgestaltete Vorrichtung, beispielsweise eine hydraulisch arbeitende Hub- bzw. Senkvorrichtung eingesetzt werden.By the reference numeral 5, a lifting and lowering device is characterized, which is pneumatically operated and by means of which the entire unit of the suction shaft 1 and roller 2 is movable in total up or down. By means of this storage or float circuit 5, the required height adjustment of the unit from the suction shaft 1 and 2 roller is possible. Instead of a pneumatic lifting or lowering device, of course, a differently configured device, for example, a hydraulically operating lifting or lowering device can be used.

Die Lagerung 5 ist so ausgeführt, dass in der im Reinigungsbetrieb gewählten Schwimmstellung eine für das Ausgleichen von Fahrbahnunebenheiten ausreichend große vertikale Bewegung der Einheit aus Saugschacht 2 und Walze 1 möglich ist.The bearing 5 is designed so that in the selected in cleaning mode floating position for the compensation of road bumps sufficiently large vertical movement of the unit from the suction shaft 2 and roller 1 is possible.

Die Lagerung 5 hat in der Schwimmstellung nicht nur die Aufgabe, eine vertikale Bewegung der Einheit zum Ausgleich von Fahrbahnunebenheiten zu ermöglichen, sondern darüber hinaus die Aufgabe, diese Einheit zu entlasten. Dies erfolgt dadurch, dass die Lagerung 5 in der Schwimmstellung eine nach oben gerichtete Kraft ausübt, die jedoch kleiner ist als die Gewichtskraft der Einheit aus Saugschacht 1 und Walze 2. Der nach unten wirkende Gewichtskraftüberschuß dient somit automatisch als Anpreßdruck der Kehrwalze 2.The storage 5 has in the floating position not only the task to allow a vertical movement of the unit to compensate for road bumps, but also the task to relieve this unit. This is done by the bearing 5 exerts an upward force in the floating position, which is smaller than the weight of the unit from the suction shaft 1 and roller 2. The downwardly acting excess weight thus serves automatically as a contact pressure of the sweeping roller. 2

Alternativ zu der in der Figur dargestellten Nachlaufwalze 2 sind auch andere mechanische Vorrichtungen, wie beispielsweise Kufen oder Schleifplatten möglich. Diese stellen dann ersatzweise den Kontakt zur Fahrbahnoberfläche 3 her. Sie ermöglichen in gleicher Weise wie die Kehrwalze 2 eine Höhenregulierung der Saugeinheit bzw. eine Einstellung des Saugspaltes 4. Die fast vollständige Aufnahme der Gewichtskraft erfolgt auch in diesem Fall über die Schwimmstellung der Hub- bzw. Senkvorrichtung bzw. der Lagerung 5.As an alternative to the follower roller 2 shown in the figure, other mechanical devices, such as runners or sanding plates are possible. These then replace the contact with the road surface 3. They allow in the same manner as the sweeping roller 2, a height adjustment of the suction unit or an adjustment of the suction gap 4. The almost complete recording of the weight is carried out in this case on the floating position of the lifting or lowering device or storage. 5

Wie dies aus der Figur hervorgeht, setzt die Lagerung 5 an derselben Position an dem Träger 7 an, wie die Verstelleinheit 6.As can be seen from the figure, the bearing 5 starts at the same position on the carrier 7 as the adjusting unit 6.

Durch die vorliegende Erfindung ist es möglich, sowohl den Abstand vom unteren Saugschachtende zur Oberfläche 3, das heißt den Saugspalt 4 als auch den Anpreßdruck der Nachlaufwalze 2 bzw. des ersatzweise eingesetzten Bauteils optimal einzustellen und auch bei Fahrbahnunebenheiten relativ konstant zu halten. Bei der in der Figur dargestellten Walze 2 handelt es sich um eine gegenläufig zur Fahrtrichtung rotierende Kehrwalze 2, die Verschmutzungen, die der Saugschacht 1 z. B. aufgrund der Reinigungsgeschwindigkeit nicht vollständig aufnehmen konnte, nach vorn in den Wirkungsbereich des Saugschachtes 1 fördert. Wie ausgeführt, kann anstelle der Kehrwalze auch ein anderes geeignetes Bauteil eingesetzt werden, das im Reinigungsbetrieb mit der Oberfläche 3 in Kontakt steht.By the present invention, it is possible to optimally adjust both the distance from the lower Saugschachtende to the surface 3, that is, the suction gap 4 and the contact pressure of the follower roller 2 and the substitute component used and also to maintain relatively constant in road bumps. The roller 2 shown in the figure is a counter-rotating to the direction of travel sweeping roller 2, the dirt, the suction shaft 1 z. B. could not completely absorb due to the cleaning speed, promotes forward into the sphere of action of the suction chute 1. As stated, instead of the sweeping roller, another suitable component can be used, which is in contact with the surface 3 in the cleaning operation.
