Description

Die Erfindung betrifft eine selbstfahrende Kehrmaschine zur Reinigung befahr- und/oder begehbarer, vorzugsweise fester Bodenoberflächen wie Verkehrsflächen, Strassen, Flughäfen und Industrieanlagen, bestehend aus einem Fahrgestell mit einer motorisch angetriebenen, und wenigstens einer zur Beeinflussung der Fortbewegungsrichtung gemeinsam lenkbare Räder aufweisende Fahrachse, die in quer zur Fortbewegungsrichtung der Kehrmaschine ausgerichtet und beabstandet hintereinander angeordnet sind, und mit einem auf dem Fahrgestell aufgebauten, zur Entleerung ausgebildeten Kehrichtsammelbehälter zur Aufnahme von Kehrgut mittels einem auf dem Fahrgestell aufgesetzten, ein Sauggebläse aufweisendes Saugaggregat, das mit einer am vorderen Ende einer Saugluftleitung angeordneten Ansaugeinrichtung leitungsverbunden ist, wobei die mit einem Saugmund ausgebildete Ansaugeinrichtung im Abstand über der Bodenoberfläche an dem Fahrgestell nach unten ragend befestigt ist, sowie einer über der Vorderachse an dem Fahrgestell aufgebauten Fahrerkabine und einer unter dieser, vor der Vorderachse angeordneten, den aufzunehmenden Kehricht resp. Schmutz zusammenführenden Kehreinrichtung.The invention relates to a self-propelled sweeper for cleaning drivable and / or walkable, preferably solid floor surfaces such as traffic areas, roads, airports and industrial plants, consisting of a chassis with a motor-driven axis having at least one common steerable wheels to influence the direction of movement, which aligned transversely to the direction of travel of the sweeping machine and spaced apart one behind the other, and with a refuse collection container built on the chassis and designed for emptying for receiving debris by means of a suction unit placed on the chassis, having a suction fan and having a suction unit at the front end of a suction air line Suction device is line-connected, the suction device formed with a suction mouth being fixed at a distance above the floor surface on the chassis so as to protrude downwards, and one above the front axle the chassis built driver's cab and one below this, arranged in front of the front axle, the garbage to be picked up, respectively. Dirt merging sweeping device.

Dabei wird die durch das Saugluftgebläse an der Ansaugeinrichtung resp. dem Saugmund erzeugte Saugluft/Saugkraft vom Kehrichtsammelbehälter nach Abscheidung des Schmutzes über eine Luftaustrittsleitung an die Umgebung zurückgeführt. Ist das Fahrgestell der Kehrmaschine ein- oder mehrteilig mit vier oder mehr Rädern ausgebildet, können die jeweils eine starre Vorderachse und/oder eine Hinterachse bildenden Räder paarweise gelenkt oder bei einer Knicklenkung, die Fahrachsen gemeinsam um senkrechte Achsen geschwenkt werden .The through the suction fan on the suction device is resp. The suction air / suction force generated by the suction mouth is returned to the environment via an air outlet line from the waste collection container after the dirt has been separated off. If the chassis of the sweeper is one-part or multi-part with four or more wheels, the wheels forming a rigid front axle and / or a rear axle can be steered in pairs or, in the case of articulated steering, the travel axles can be pivoted together about vertical axes.

Bei einem zweiteiligen Fahrgestell sind der vordere und der hintere Fahrgestellteil als Lenkhilfe der Kehrmaschine durch gesteuerte Kolben-Zylinder-Einheiten um eine senkrechte Achse schwenkbar verbunden.In the case of a two-part chassis, the front and rear chassis parts are pivotably connected about a vertical axis as a steering aid for the sweeping machine by means of controlled piston-cylinder units.

Durch die DE 199 35 887 C1 ist ein Fahrzeug zum Säubern einer Oberfläche bekannt, das einen Saugschacht zum Heben und Senken mittels einer Vorrichtung aufweist, die mindestens aus einem Sensor zum Erfassen des Profils der in Fahrtrichtung vor dem Saugschacht liegenden Oberfläche und einer Steuerung zum Ansteuern der Vorrichtung zum Heben bzw. Senken des Saugschachtes in Abhängigkeit von dem durch den Sensor erfassten Oberflächenprofil besteht.Through the DE 199 35 887 C1 a vehicle for cleaning a surface is known, which has a suction shaft for lifting and lowering by means of a device which consists of at least one sensor for detecting the profile of the surface in front of the suction shaft in the direction of travel and a control for controlling the device for lifting or lowering of the suction shaft as a function of the surface profile detected by the sensor.

In der US 2002/0133981 A1 ist ein Steuersystem für einen Schneepflug beschrieben, bei dem der sich ändernde Abstand zwischen Einrichtungsgestell und Boden oder Radachse als Massgabe zur Anhebung oder Absenkung des Pflugschildes verwendet wird.In the US 2002/0133981 A1 describes a control system for a snow plow in which the changing distance between the equipment frame and the ground or wheel axle is used as a measure for raising or lowering the plow blade.

Die Kehrmaschine nach der EP 2 775 034 A1 mit einem Schmutzsammelbehälter, an welchen einerseits ein Sauggebläse und andererseits über eine Saugleitung ein Saugkopf mit einem Saugschacht und ein sich in Arbeitsrichtung vor diesem erstreckenden flächigen Strömungsleitelement angeschlossen sind, ist letzteres bei gleichbleibender Position des Saugschachtes durch eine am vorderen Randbereich angreifende Verstellvorrichtung ausgebildet, so dass das Strömungsleitelement zwischen einer gewölbten Form mit geringem Abstand und einer gestreckten Form mit grösserem Abstand zur Bodenoberfläche hin veränderbar ist.The sweeper after the EP 2 775 034 A1 with a dirt collecting container, to which on the one hand a suction fan and on the other hand via a suction line a Suction head with a suction shaft and a flat flow guide element extending in front of this in the working direction are connected, the latter is formed by an adjusting device acting on the front edge area with the suction shaft in the same position, so that the flow guide element between a curved shape with a small distance and an elongated shape with a larger Distance to the ground surface can be changed.

In der Praxis weisen selbstfahrende Kehrmaschinen auf Rädern oder Kufen geführte Saugschächte auf und sind durch den Kontakt zur Bodenoberfläche einem starken Versch!eiss unterworfen und deshalb von hohen Unterhaltskosten begleitet.In practice, self-propelled sweepers have suction shafts guided on wheels or runners and are subject to heavy wear and tear due to contact with the ground surface and are therefore accompanied by high maintenance costs.

Weiterhin werden Saugmünder von Kehrmaschinen vor der Vorderachse angeordnet/vorgelagert, sodass sie beim Auftreffen auf Hindernisse einer Beschädigung mit Betriebsunterbruchfolge ausgesetzt sind.Furthermore, suction nozzles of sweeping machines are arranged / positioned in front of the front axle so that they are exposed to damage with operational interruption when they hit obstacles.

Die vorgelagerte Position erfordert einen langen und flach geführten, an den Saugmund angeschlossenen Saugschlauch, der hinter der Fahrerkabine in den Kehrichtsammelbehälter mündet. Daraus entwickelt sich eine Verstopfungsgefahr im Saugschlauch. Eine teilweise Verlegung des Saugschlauches in die Fahrerkabine schränkt den Freiraum ein und erhöht den Betriebslärm, schränkt die Betriebssicherheit ein.The upstream position requires a long, flat suction hose that is connected to the suction mouth and opens into the refuse bin behind the driver's cab. This creates a risk of clogging in the suction hose. A partial relocation of the suction hose in the driver's cab restricts the free space and increases operational noise, and restricts operational safety.

Es hat sich an die vorliegende Erfindung die Aufgabe gestellt, die erwähnten Nachteile zu beheben und eine gegenüber der zu reinigenden Bodenoberfläche berührungslose Aufhängung für die mit dem Fahrgestell verbundene Ansaugeinrichtung einer Kehrmaschine zu schaffen, derart, dass deren Arbeitsposition jeweils an die befahrbare Bodenoberfläche angepasst ist.The object of the present invention is to eliminate the disadvantages mentioned and to create a suspension for the suction device of a sweeping machine connected to the chassis, which is contactless with respect to the floor surface to be cleaned, in such a way that its working position is adapted to the floor surface that can be driven on.

Erfindungsgemäss ist die Aufgabe dadurch gelöst, dass die in Bodennähe zwischen den Rädern einer eine Einzelradaufhängung oder eine Starrachse aufweisenden Vorderachse schwebend angeordnete Ansaugeinrichtung mit die Radaufhängung der Vorderachse bildenden, um eine etwa horizontale Achse an der Fahrgestell schwenkbar abgestützten Radträgern anheb- und absenkbar verbunden und an einem Lenker in etwa einer bodenparallelen Ebene versetz- resp. verschwenkbar geführt ist.
Diese Ausführung könnte sowohl bei einem knickgelenkten Fahrgestell einer Kehrmaschine wie auch bei einer Kehrmaschine mit Starrachsen angewendet werden. Die Lenkung der Maschine könnte manuell oder elektronisch gesteuert ausgebildet sein.According to the invention, the object is achieved in that the suction device, which is floatingly arranged near the ground between the wheels of a front axle having an independent wheel suspension or a rigid axle, is connected and lowerable to the wheel suspension of the front axle and is pivotably supported about an approximately horizontal axis on the chassis a handlebar in approximately a plane parallel to the ground offset respectively. is pivotably guided.
This design could be used both with an articulated chassis of a sweeper and with a sweeper with rigid axles. The machine could be steered manually or electronically.

Die Ansaugeinrichtung kann aufgrund ihrer Einfachheit einem vorderen oder hinteren Fahrgestellteil zugeordnet werden, ohne dass dafür besondere Vorkehrungen zu treffen sind.Due to its simplicity, the suction device can be assigned to a front or rear chassis part without special precautions having to be taken.

Vorzugsweise ist die Ansaugeinrichtung mit den Radträgern steuerwirksam zugeordneter Übertragungsvorrichtung einerseits und durch den Lenker mit dem Fahgestell andererseits hängend verbunden, sodass eine einfache stabile und robuste Ausführungsform entsteht.The suction device is preferably connected in a suspended manner to the transmission device assigned to the wheel carriers for control purposes, on the one hand, and to the bogie, on the other hand, through the handlebar, so that a simple, stable and robust embodiment is created.

Als geeignet und einfach erweisen sich als Übertragungsvorrichtung Hebelarme zur Übertragung der Bewegungen der Radträger aufgrund befahrener, unebener Verkehrsflächen.As a transmission device, lever arms have proven to be suitable and simple for transmitting the movements of the wheel carriers due to uneven traffic areas being traveled on.

Es ist möglich, dass die Hebelarme einenends an dem Fahrgestell angelenkt sind und zwischen angelenktem und dem mit der Ansaugeinrichtung verbundenen, schwenkbaren Heblarmende ein auf dem Radträger sich abstützendes Steuerelement aufweisen.It is possible for the lever arms to be hinged to the chassis at one end and to have a control element supported on the wheel carrier between the hinged end of the lever arm and the pivotable end of the lever arm connected to the suction device.

Bei einer weiteren Möglichkeit kann zur Einstellung und Änderung oder Verstellung der Ansaugeinrichtung zur Bodenoberfläche hin das am Hebelarm befestigte Steuerelement und/oder der Lenker in ihrer Länge verstellbar ausgebildet sein.In a further possibility, the control element attached to the lever arm and / or the link can be designed to be adjustable in length for setting and changing or adjusting the suction device towards the floor surface.

Selbstverständlich können die freien Enden der Hebelarme durch starre oder flexible Verbindungselemente mit der Ansaugeinrichtung verbunden sein, wobei sich diese Verbindung als anspruchslos zur Bedienung erweist.Of course, the free ends of the lever arms can be connected to the suction device by rigid or flexible connecting elements, this connection proving to be undemanding for operation.

Das Steuerelement kann in Abstimmung mit der Oberseite eines Radträgers und den verfügbaren räumlichen Gegebenheiten wahlweise auf der Hebelarmlänge befestigt sein.The control element can be optionally attached to the length of the lever arm in coordination with the top of a wheel carrier and the available spatial conditions.

Vorteilhaft ist das der Ansaugeinrichtung zugewandte Ende des Lenkers durch ein sphärische Gelenk/Lager ausgebildet, sodass auch räumliche Bewegungen aufgenommen werden können.The end of the link facing the suction device is advantageously formed by a spherical joint / bearing, so that spatial movements can also be recorded.
