Description

Die vorliegende Erfindung bezieht sich auf ein Fahrzeug sowie ein Verfahren zum Säubern einer Oberfläche.The present invention relates to a vehicle and a method for Clean a surface.

Ein aus der DE 40 01 088 C2 bekanntes Fahrzeug zum Reinigen einer Oberfläche ist in Figur 2 gezeigt und weist zwischen den Vorderrädern 1a und Hinterrädern 1b einen Besen 7 auf , welcher Kehricht und ähnliche Verunreinigungen einer zu kehrenden Straße zusammenkehrt, um somit bei Bewegung des Fahrzeugs nach vorne einen länglichen Haufen an Kehricht zu bilden, welcher von einem dem Besen 7 nachlaufenden Saugschacht 6 aufgesaugt wird. Der Saugschacht 6 ist fest mit einem an der gegenüberliegenden Seite seiner Öffnung angeordneten Laufrad 11 verbunden. Laufrad 11 und Saugschacht 6 sind in vertikaler Richtung schwenkbar gelagert, so daß Unebenheiten der Straße ausgeglichen werden können. Fährt das Reinigungsfahrzeug zum Beispiel über eine kleine Erhebung, so wird die Ansaugöffnung des Saugschachtes 6 durch das über die Erhebung rollende Laufrad 11 ebenfalls angehoben, um einen bestimmten Abstand h des Saugschachtes 6 von der zu reinigenden Straße sicherzustellen. A vehicle known from DE 40 01 088 C2 for cleaning a surface is shown in Figure 2 and has between the front wheels 1a and rear wheels 1b a broom 7, which rubbish and similar impurities one to be swept Road converges to move forward as the vehicle moves to form an elongated pile of rubbish, which from a broom 7 trailing suction shaft 6 is sucked up. The suction shaft 6 is fixed with a impeller 11 arranged on the opposite side of its opening connected. Impeller 11 and suction shaft 6 can be pivoted in the vertical direction stored so that bumps in the road can be compensated. Does that Cleaning vehicle, for example, via a small elevation, so is the intake opening of the suction shaft 6 by the impeller 11 rolling over the elevation also raised by a certain distance h of the suction shaft 6 from the road to be cleaned.

Wenn jedoch eine Bedienungsperson unaufmerksam ist, oder größere Unebenheiten wie zum Beispiel Bordsteine von dem Reinigungsfahrzeug überfahren werden, so kann es am Saugschacht 6 oder auch am Besen 7 zu Beschädigungen kommen, da zum Beispiel eine überfahrene Bordsteinkante zur Deformation des Saugschachtes 6 oder des Besens 7 führen kann. Das dem Saugschacht 6 in Bewegungsrichtung nachfolgende Laufrad 10 kann in diesem Fall den Saugschacht 6 nicht anheben, so daß die stetige Aufmerksamkeit einer Bedienungsperson erforderlich ist.However, when an operator is inattentive, or major bumps such as curbs being run over by the cleaning vehicle, this can damage the suction shaft 6 or the broom 7, because, for example, a curb run over to deform the suction shaft 6 or 7 of the broom. That the suction shaft 6 in the direction of movement following impeller 10 can in this case suction shaft 6 do not raise so that the constant attention of an operator is required is.

Aus der EP 0 189 371 A1 ist ein Schneeräumfahrzeug bekannt, bei dem ein Kehrbesen sowie ein Gebläseschacht heb- und senkbar ausgebildet sind. Der Kehrbesen wird mit einer konstanten Andrückkraft nach unten in seine Arbeitsstellung gedrückt, um eine konstante Kehrwirkung zu erreichen.A snow removal vehicle is known from EP 0 189 371 A1, in which a broom is used and a fan shaft can be raised and lowered. The broom is pressed down into its working position with a constant pressing force, to achieve a constant sweeping effect.

Aus der DE 41 28 879 A1 ist ein Kehrfahrzeug bekannt, bei dem ein Saugschacht höhenverstellbar ausgebildet ist. In Abhängigkeit der Dichte des einzusaugenden Kehrichtgutes und der Höhe des Kehrichts wird die Höhenstellung des Saugschachtes sowie die Gebläseleistung geregelt, um mit minimaler Gebläseleistung eine gute Saugwirkung zu erreichen und die Wirtschaftlichkeit zu optimieren.From DE 41 28 879 A1 a sweeper is known in which a suction shaft is adjustable in height. Depending on the density of the material to be sucked in Rubbish and the height of the rubbish becomes the height of the suction shaft as well as the blower power regulated to with minimal blower power to achieve a good suction effect and to optimize economy.

Schließlich ist aus der EP 0 372 258 A2 ein Straßenkehrfahrzeug bekannt, bei dem eine Besenwalze höhenverstellbar ausgebildet ist, um den Kehrspiegel der Besenwalze trotz Verschleiß derselben konstant halten zu können. In Abhängigkeit des erfaßten Ist-Durchmessers der Besenwalze und einem zeitlichen Mittelwert der erfaßten Ist-Höhe der Walzenachse wird die Größe des Kehrspiegels, d. h. die Fläche, über die die Besenwalze den Boden berührt, auf einem Soll-Wert geregelt. Auch hier besteht jedoch die Gefahr von Beschädigungen beim Überfahren von Hindernissen wie z. B. Bordsteinen und dergleichen.Finally, a street sweeper is known from EP 0 372 258 A2, in which a broom roller is height adjustable to the sweeping mirror of the broom roller to be able to keep it constant despite wear. Depending on the detected actual diameter of the broom roller and a time average of the detected The actual height of the roller axis is the size of the sweeping mirror, i.e. H. the area, via which the broom roller touches the floor, regulated to a target value. However, here too there is a risk of damage when driving over Obstacles such as B. curbs and the like.

Es ist die Aufgabe der Erfindung ein Fahrzeug, sowie ein Verfahren zum Säubern einer Oberfläche vorzuschlagen, welche eine Beschädigung eines Saugschachtes verhindern kann. It is the object of the invention a vehicle and a method for cleaning to propose a surface that damages a suction shaft can prevent.

Diese Aufgabe wird durch die Merkmale der unabhängigen Ansprüche gelöst. Vorteilhaft Ausführungsformen ergeben sich aus den Unteransprüchen.This object is solved by the features of the independent claims. Advantageous Embodiments result from the subclaims.

Das erfindungsgemäße Fahrzeug zum Säubern einer Oberfläche weist einen Saugschacht auf, welcher im Bezug auf das Fahrzeug mittels einer geeigneten Vorrichtung heb- oder senkbar ist. Somit kann der Abstand des Saugschachtes beziehungsweise der Saugschachtöffnung von der zu säubernden Oberfläche bei gegebener Straßenlage des Fahrzeuges verändert werden. An dem Fahrzeug ist mindestens ein Sensor zum Erfassen des Profils der zu reinigenden Oberfläche vorgesehen. Dieser Sensor gibt Signale an eine Steuervorrichtung aus, welche die Vorrichtung zum Heben beziehungsweise Senken des Saugschachtes in Abhängigkeit von den von dem Sensor erfaßten Signalen zum Ermitteln des Oberfächenprofiles ansteuert. Somit kann das untere Ende des Saugschachtes 6 beziehungsweise die Saugschachtöffnung dem Oberflächenprofil angepaßt geführt werden, so daß zum Beispiel ein konstanter Abstand h zur Oberfläche eingehalten wird. Bei geeigneter Anordnung des mindestens einen Sensors beziehungsweise mehrerer Sensoren kann somit sichergestellt werden, daß plötzliche Unebenheiten der Oberfläche, wie zum Beispiel Bordsteinkanten oder ähnliches, rechtzeitig von den Sensoren im Betrieb des Fahrzeuges erfaßt werden und der Saugschacht entsprechend angehoben oder abgesenkt wird, so daß es zu keiner Kollision des Saugschachtes mit einer Bodenunebenheit kommt. Dabei kann ein gewünschter Abstand des Saugschachtes zur Bodenoberfläche sichergestellt werden . Eine Beschädigung des Saugschachtes kann zuverlässig vermieden werden, so daß eine Bedienungsperson nicht mehr auf größerer Bodenunebenheiten achten muß und somit in ihrer Aufmerksamkeit nicht von dem Straßenverkehr abgelenkt wird.The vehicle according to the invention for cleaning a surface has one Suction shaft, which in relation to the vehicle by means of a suitable device can be raised or lowered. Thus, the distance of the suction shaft or the suction shaft opening from the surface to be cleaned at a given Road position of the vehicle can be changed. At least on the vehicle a sensor for detecting the profile of the surface to be cleaned is provided. This sensor outputs signals to a control device, which the device for lifting or lowering the suction shaft depending of the signals detected by the sensor for determining the surface profile controls. Thus, the lower end of the suction shaft 6 or the Suction shaft opening are adapted to the surface profile, so that the Example, a constant distance h to the surface is maintained. With more suitable Arrangement of the at least one sensor or a plurality of sensors can thus be ensured that sudden bumps in the surface, such as for example curbs or the like, timely from the sensors in operation of the vehicle can be detected and the suction shaft raised accordingly or is lowered so that there is no collision of the suction shaft with a Uneven ground comes. In this case, a desired distance of the suction shaft to the floor surface. Damage to the Suction shaft can be reliably avoided, so that an operator no longer has to pay attention to larger bumps and therefore in their Attention is not distracted from road traffic.

Vorteilhaft ist in Fahrtrichtung vor dem Saugschacht ein Besen angeordnet, mit welchem über eine gewisse Breite quer zur Fahrtrichtung Kehricht und ähnliches zusammengekehrt werden kann, um somit während des Fahrens einen Kehrichthaufen zu bilden, welcher von dem nachfolgenden Saugschacht aufgenommen werden kann. Somit muß der Saugschacht nicht über die ganze Breite der zu reinigenden Fläche ausgeführt sein, sondern kann an einem bestimmten Bereich vorgesehen sein, an welchem bei sich bewegendem Fahrzeug der Saugschacht an dem von dem Besen zusammengekehrten Kehricht vorbeifährt. Der Besen kann auch als rotierender Tellerbesen oder eine Mehrzahl von nebeneinander angeordneten Besen beziehungsweise Tellerbesen ausgebildet sein, um so die Reinigungswirkung zu verbessern. Es ist jedoch auch denkbar, das erfindungsgemäße Fahrzeug ohne einen Besen, nur mit einem Saugschacht zum Reinigen auszugestalten, so daß von dem Boden zu entfernende Verunreinigungen von dem Saugschacht direkt aufgenommen werden.A broom is advantageously arranged in the direction of travel in front of the suction shaft which over a certain width across the direction of travel garbage and the like can be swept together, thus a pile of rubbish while driving to form, which is taken up by the subsequent suction shaft can be. Thus, the suction shaft does not have to be cleaned across the entire width Surface can be executed, but can be provided in a certain area on which the suction shaft is on when the vehicle is moving drives past the rubbish swept up by the broom. The broom can also as a rotating plate brush or a plurality of juxtaposed Brooms or plate brooms can be designed to improve the cleaning effect to improve. However, it is also conceivable that the invention Vehicle without a broom, only with a suction shaft for cleaning, so that contaminants to be removed from the floor are removed from the suction duct be recorded directly.

Bevorzugt kann auch der Besen, ebenso wie der Saugschacht, so angesteuert werden, daß in Abhängigkeit von dem durch den mindestens einen Sensor erfaßten Oberflächenprofil die Lage des Besens, also zum Beispiel der Kippwinkel oder der Abstand vom Boden, eingestellt werden.The broom, like the suction shaft, can preferably also be controlled in this way be that depending on that detected by the at least one sensor Surface profile the position of the broom, for example the tilt angle or the Distance from the ground.

Es ist vorteilhaft mindestens zwei Sensorelemente zu verwenden, wobei ein Sensorelement in Fahrtrichtung vor dem Saugschacht und ein Sensorelement in Fahrtrichtung hinter dem Saugschacht angeordnet ist. Dadurch kann sichergestellt werden, daß sowohl bei einer Vorwärts-, als auch bei einer Rückwärtsfahrt des Fahrzeuges das Oberflächenprofil ausreichend erfaßt werden kann, um den Saugschacht beziehungsweise dessen Abstand von der Oberfläche beziehungsweise Höhe geeignet einzustellen. Entsprechend können die Sensoren auch vor und hinter dem Besen angeordnet sein.It is advantageous to use at least two sensor elements, one sensor element in the direction of travel in front of the suction shaft and a sensor element in the direction of travel is arranged behind the suction shaft. This can ensure that both when driving forward and when driving the vehicle in reverse the surface profile can be detected sufficiently around the suction shaft or its distance from the surface or Adjust height appropriately. Accordingly, the sensors can also be in front and behind be arranged on the broom.

Als Sensorelemente zum Erfassen des Oberflächenprofils können zum Beispiel Infrarot-, Ultraschall-, Radar- oder andere geeignete Sensoren eingesetzt werden, mit welchen zum Beispiel eine auf Laufzeitauswertung basierende Abstandsmessung oder eine Aufnahme eines Oberflächenprofils möglich ist.For example, as sensor elements for detecting the surface profile Infrared, ultrasonic, radar or other suitable sensors are used, with which, for example, a distance measurement based on runtime evaluation or a recording of a surface profile is possible.

Die Vorrichtung zum Heben beziehungsweise Senken des Saugschachtes oder Besens kann zum Beispiel als eine Kolben-Zylinder-Einheit ausgebildet sein, welche zum Beispiel auf einem pneumatischen oder hydraulischen Mechanismus basiert. Es ist jedoch auch denkbar die Einstellung der Höhe des Saugschachtes mittels eines Elektromotors oder einer anderen geeigneten Vorrichtung vorzunehmen, wie zum Beispiel einem am Fahrzeug angebrachten Luftbalg, welcher durch geeignetes Beaufschlagen mit Druckluft eine Hub- beziehungsweise Absenkkraft auf den Saugschacht erzeugt.The device for lifting or lowering the suction shaft or Broom can be designed, for example, as a piston-cylinder unit, which for example based on a pneumatic or hydraulic mechanism. However, it is also conceivable to adjust the height of the suction shaft an electric motor or another suitable device, such as an air bellows attached to the vehicle, which by suitable Applying compressed air has a lifting or lowering force on the Suction shaft created.

Beim erfindungsgemäßen Verfahren zum Säubern einer Oberfläche wird eine Verunreinigung der Oberfläche, wie zum Beispiel Kehricht, von einem Saugschacht aufgenommen. Dabei wird das Profil der Oberfläche erfaßt und der Abstand des Saugschachtes zu der Oberfläche in Abhängigkeit von dem erfaßten Oberflächenprofil eingestellt. Hierdurch können die oben beschriebenen Vorteile erzielt werden.In the method according to the invention for cleaning a surface, contamination becomes the surface, such as rubbish, from a suction shaft added. The profile of the surface is recorded and the distance of the Suction shaft to the surface depending on the surface profile detected set. In this way, the advantages described above can be achieved.

Bevorzugt kann auch die Lage eines Besens, wie zum Beispiel Kippwinkel oder Abstand zur Oberfläche, in Abhängigkeit von dem erfaßten Oberflächenprofil eingestellt werden. Es ist auch denkbar nur eine Regelung für den Besen allein vorzusehen.The position of a broom, such as, for example, tilt angle or Distance to the surface, depending on the detected surface profile become. It is also conceivable to provide only one regulation for the broom alone.

Vorteilhaft wird der Abstand des Saugschachtes beziehungsweise des unteren Bereiches des Saugschachtes oder der Saugschachtöffnung, gegebenenfalls auch des Besens, zu der Oberfläche so eingestellt, daß im wesentlichen ein konstanter Abstand eingehalten wird, so daß die Saugschachtöffnung oder der Besen auch bei unebener Oberfläche immer einen Abstand von zum Beispiel 5 Zentimeter vom Boden aufweist.The distance between the suction shaft and the lower area is advantageous of the suction shaft or the suction shaft opening, if necessary also of the broom, set to the surface so that essentially a constant Distance is maintained so that the suction shaft opening or the broom also uneven surface always a distance of, for example, 5 centimeters from the floor having.

Es ist weiter vorteilhaft die Höhe der Saugschachtöffnung beziehungsweise die Lage des Besens so zu regeln, daß plötzlich Bodenunebenheiten, wie zum Beispiel Bordsteinkanten, ein rechtzeitiges Anheben des Saugschachtes oder Besens bewirken, so daß eine entsprechenden Regelung zum Beispiel neben den aufgenommenen Sensorsignalen auch die momentane Fahrgeschwindigkeit des Fahrzeuges berücksichtigt. Somit ist es möglich einen gewünschten Abstand der Saugschachtöffnung von der zu reinigenden Oberfläche bei einer beliebigen Geschwindigkeit des Fahrzeuges sicherzustellen, wobei zum Beispiel bei einer durch einen Sensor erkannten Bordsteinkante ein Hubvorgang des Saugschachtes bei höherer Geschwindigkeit eher eingeleitet wird, als bei einer langsameren Geschwindigkeit.It is also advantageous the height of the suction shaft opening or the position regulate the broom so that suddenly bumps in the floor, such as Curbs, timely lifting of the suction shaft or broom, so that a corresponding regulation for example in addition to the added Sensor signals also the current driving speed of the vehicle considered. It is thus possible to have a desired distance between the suction shaft opening from the surface to be cleaned at any speed to ensure the vehicle, for example with one by one Sensor recognized the curb by lifting the suction shaft at a higher level Speed is initiated rather than at a slower speed.

  • Figure 2 shows a vehicle from the prior art.

    • Figur 1 zeigt die Unterseite eines erfindungsgemäßen Fahrzeugs zum Reinigen einer Oberfläche. Zwischen einem vorderen Rad 1a und einem hinteren Rad 1b sind in Fahrtrichtung vorne ein rotierender Tellerbesen 7 und diesem Besen 7 nachlaufend ein Saugschacht 6 angeordnet. Mit den beispielhaft eingezeichneten Sensorelementen 10 kann das Profil der zu reinigenden Oberfläche erfaßt werden, auf welchem die Räder 1a, 1b des Fahrzeuges laufen. Erkennt ein Sensor 10 eine Bodenunebenheit 12, so werden die übermittelten Signale des Sensors 10 von einer geeigneten Steuerung in Ansteuersignale des Saugschachtes 6 beziehungsweise des Besens 7 umgesetzt, so daß der Saugschacht 6 beziehungsweise der Besen 7 rechtzeitig vor Erreichen der Bordsteinkante 12 angehoben werden, um eine Beschädigung dieser Teile zu verhindern. Fährt das Fahrzeug zum Beispiel mit dem vorderen Rad 1a über die Bordsteinkante 12, so wird von der Steuerung unter Berücksichtigung der Geschwindigkeit des Fahrzeuges zunächst der Besen 7 angehoben, woraufhin der Saugschacht 6 kurz vor Erreichen der Bordsteinkante 12 ebenfalls angehoben wird. Hierzu wird der aus dem hydraulischen Zylinder 8a herausragende Kolben 8b in den Zylinder 8a eingefahren, um den Saugschacht 6 in Bezug auf das Fahrzeug einzufahren und die Saugschachtöffnung anzuheben. Der Saugschacht 6 ist in seinem oberen Bereich über eine verformbare Verbindung mit einer nicht gezeigten Saugvorrichtung verbunden, so daß eine gewünschte Saugkraft in jeder Position des Saugschachtes 6 realisiert werden kann. Figure 1 shows the underside of a vehicle according to the invention for cleaning a surface. Between a front wheel 1a and a rear wheel 1b are a rotating circular broom 7 and this broom 7 in the direction of travel trailing a suction shaft 6 arranged. With the examples shown Sensor elements 10 can detect the profile of the surface to be cleaned, on which the wheels 1a, 1b of the vehicle run. If a sensor 10 detects one Uneven ground 12, the transmitted signals of the sensor 10 from a suitable control in control signals of the suction shaft 6 or of the broom 7 implemented so that the suction shaft 6 or Brooms 7 to be raised in time before reaching curb 12 to prevent damage to these parts. For example, the vehicle drives with the front wheel 1a over the curb 12, so the control taking into account the speed of the vehicle, first the broom 7 raised, whereupon the suction shaft 6 shortly before reaching the curb 12th is also raised. For this purpose, the protruding from the hydraulic cylinder 8a Piston 8b retracted into the cylinder 8a to the suction shaft 6 in Retract with respect to the vehicle and lift the suction shaft opening. The Suction shaft 6 is in its upper area with a deformable connection connected to a suction device, not shown, so that a desired suction force can be realized in any position of the suction shaft 6.

    Ebenso wie die Kolben-Zylinder-Einheit 8a, 8b zum Bewegen des Saugschachtes 6 ist einen Kolben-Zylinder-Einheit 5a, 5b zum Anheben beziehungsweise Absenken des Besens 7 vorgesehen. Über geeignete Steilvorrichtungen kann weiter der Neigungswinkel des Besens 7 verändert werden, so daß er aus seiner gestrichelt eingezeichneten waagrechten angehobenen Position in eine abgesenkte schräg gestellte Position gebracht werden kann, um eine gewünschte Reinigung der Oberfläche zu bewirken.Just like the piston-cylinder unit 8a, 8b for moving the suction shaft 6 is a piston-cylinder unit 5a, 5b for raising or lowering the broom 7 provided. The angle of inclination can be further adjusted by means of suitable steep devices of the broom 7 can be changed so that it is drawn from his dashed horizontally raised position to a lowered inclined position Position can be brought to a desired cleaning of the surface to effect.
