Im Weiteren weist das Räumfahrzeug ein am Traggestell angeordnetes Gebläse und einen Hohlkörper zur Leitung der Blasluft von dem Gebläse zur Blasluftvorrichtung auf. Ferner betrifft die Erfindung ein Verfahren zum Betrieb eines Räumfahrzeugs.The invention relates to a clearing vehicle with a support frame and a Kehrblasanordnung which is adjustable pivotable about a running through the clearing vehicle vertical axis relative to the support frame and comprises a blown air device. Furthermore, the clearing vehicle has a blower arranged on the support frame and a hollow body for guiding the blown air from the blower to the blown air device.

Hintergrundbackground

Aus EP3042996 ist ein Schneeräumfahrzeug bekannt, welches eine Kehrwalzenbürste und eine Kehrblasanordnung aufweist zum Abführen von Schnee mittels eines Luftstroms. Die Kehrblasanordnung weist mehrere Blasluftöffnungen zum gleichzeitigen, gleichwirkenden Blasen auf. Angestrebt wird eine möglichst gleichmässige Blasluftverteilung entlang der Kehrwalzenbürste für eine deutlich bessere Abfuhr des vom Pflug zurück gelassenen Schnees bzw. des von der Kehrwalzenbürste gelösten Schnees.Out EP3042996 For example, there is known a snow sweeper vehicle having a sweeping brush and a sweeping blast assembly for removing snow by means of an air flow. The Kehrblasanordnung has a plurality of blown air openings for simultaneous, equal acting bubbles. The aim is a uniform as possible Blasluftverteilung along the brush roller brush for a significantly better removal of the left behind by the plow snow or of the sweeping brush dissolved snow.

Die Kehrblasanordnung ist um eine durch das Räumfahrzeug verlaufende Vertikalachse einstellbar verschwenkbar. Sie kann dabei in unterschiedliche Arbeitspositionen oder in eine Transportposition geschwenkt werden.The Kehrblasanordnung is adjustable pivotable about a vertical axis extending through the clearing vehicle. It can be pivoted in different working positions or in a transport position.

Solche Schneeräumfahrzeuge haben sich bewährt. Sie werden insbesondere für die Schneeräumung auf Start- und Landebahnen für Flugzeuge eingesetzt, wo grosse Schneemengen rasch beseitigt werden müssen.Such snow removal vehicles have proven themselves. They are especially for snow removal Runways are used for aircraft, where large amounts of snow must be quickly removed.

Darstellung der ErfindungPresentation of the invention

Der Erfindung liegt die Aufgabe zu Grunde, ein verbessertes Räumfahrzeug zu schaffen. Insbesondere soll die Kehrblasanordnung einfacher geschwenkt werden können.The invention is based on the object to provide an improved clearing vehicle. In particular, the Kehrblasanordnung should be easier to pivot.

Diese Aufgabe wird gemäss dem unabhängigen Vorrichtungsanspruch gelöst.This object is achieved according to the independent device claim.

Demgemäss umfasst das Räumfahrzeug, welches bevorzugt ein Schneeräumfahrzeug ist, ein Traggestell und eine Kehrblasanordnung. Die Kehrblasanordnung ist um eine durch das Räumfahrzeug verlaufende Vertikalachse gegenüber dem Traggestell einstellbar schwenkbar angeordnet. Ebenfalls umfasst die Kehrblasanordnung eine Blasluftvorrichtung.Accordingly, the clearing vehicle, which is preferably a snow removal vehicle, comprises a support frame and a sweeping blast assembly. The Kehrblasanordnung is adjustably arranged pivotably about a running through the clearing vehicle vertical axis relative to the support frame. Also, the Kehrblasanordnung comprises a blown air device.

Im Weiteren umfasst das Räumfahrzeug ein an dem Traggestell angeordnetes Gebläse zur Erzeugung von Blasluft und einen Hohlkörper zur Leitung der Blasluft von dem Gebläse zur Blasluftvorrichtung.Furthermore, the clearing vehicle comprises a blower arranged on the support frame for generating blown air and a hollow body for guiding the blown air from the blower to the blown air device.

Die Kehrblasanordnung mit der Blasluftvorrichtung ist mit einer ersten Schwenkbewegung in eine Arbeitsstellung und mit einer zweiten Schwenkbewegung in eine Transportstellung schwenkbar.The Kehrblasanordnung with the blown air device is pivotable with a first pivoting movement in a working position and with a second pivoting movement in a transport position.

Das Schwenken in die Transportstellung ist insbesondere dann vorgesehen, wenn das Räumfahrzeug über längere Strecken mit erhöhter Geschwindigkeit bewegt werden soll, ohne dass die Kehrblasanordnung in Betrieb ist und auch wenn das Räumfahrzeug geparkt wird. In die Arbeitsstellung wird dann ausgeschwenkt, wenn die Kehrblasanordnung betrieben werden soll.The pivoting into the transport position is particularly provided when the clearing vehicle is to be moved over long distances at an increased speed without the Kehrblasanordnung is in operation and even if the clearing vehicle is parked. In the working position is then swung out when the Kehrblasanordnung to be operated.

Der Hohlkörper und die Blasluftvorrichtung sind derart ausgestaltet und angeordnet, dass sie durch die erste Schwenkbewegung in Blasluftverbindung bringbar sind und durch die zweite Schwenkbewegung die Blasluftverbindung aufhebbar ist.The hollow body and the blown air device are configured and arranged such that they can be brought into blown air connection by the first pivoting movement are and the blown air connection can be canceled by the second pivoting movement.

Dies führt zum Ergebnis, dass der Hohlkörper und die Blasluftvorrichtung in der Transportstellung nicht zur Leitung von Blasluft verbunden sind. In der Arbeitsstellung ist die Blasluftverbindung allerdings gewährleistet und Blasluft kann vom Hohlkörper zur Blasluftvorrichtung geleitet werden.This leads to the result that the hollow body and the blown air device are not connected in the transport position for guiding blown air. In the working position, however, the blown air connection is ensured and blowing air can be passed from the hollow body to the blown air device.

Dies hat den Vorteil, dass die Blasluftverbindung zwischen Hohlkörper und Blasluftvorrichtung durch die Schwenkbewegung erstellt werden kann, und es beispielsweise nicht erforderlich ist, den Hohlkörper oder die Blasluftvorrichtung von Hand in Position zu bringen, um die Blasluftverbindung zu erstellen. Dadurch muss der Fahrer des Räumfahrzeugs beim Schwenken von der Transportstellung in die Arbeitsstellung das Fahrzeug nicht verlassen, um den Hohlkörper und die Blasluftvorrichtung in Blasluftverbindung zu bringen.This has the advantage that the blast air connection between the hollow body and blown air device can be created by the pivoting movement, and it is not necessary, for example, to manually bring the hollow body or the blower device in position to create the blast air connection. As a result, the driver of the clearing vehicle does not have to leave the vehicle when swiveling from the transport position to the working position in order to bring the hollow body and the blown air device into blown air connection.

Grundsätzlich könnten der Hohlkörper und die Blasluftvorrichtung über die gesamte Schwenkbewegung, d.h. auch in der Transportstellung, verbunden bleiben, sodass kein Erstellen und Aufheben der Blasluftverbindung notwendig wäre. Dies ist allerdings angesichts der komplexen Ausgestaltung des Räumfahrzeuges, insbesondere des Trägers und des Hohlkörpers, konstruktiv kaum oder zumindest nur mit Schwierigkeiten zu bewerkstelligen.Basically, the hollow body and the blown air device could over the entire pivoting movement, i. remain connected in the transport position, so that no creation and cancellation of the blast air connection would be necessary. However, in view of the complex configuration of the clearing vehicle, in particular of the carrier and the hollow body, this is structurally difficult or at least difficult to accomplish.

Aus diesen Gründen hat sich deshalb gezeigt, dass es vorteilhaft ist, den Hohlkörper und die Blasluftvorrichtung durch eine erste Schwenkbewegung in Blasluftverbindung zu bringen und die Blasluftverbindung durch eine zweite Schwenkbewegung aufzuheben.For these reasons, therefore, it has been shown that it is advantageous to bring the hollow body and the blown air device by a first pivoting movement in blown air connection and cancel the blast air connection by a second pivoting movement.

Im Weiteren kann das Räumfahrzeug eine Koppelvorrichtung zur Kopplung des Hohlkörpers und der Blasluftvorrichtung aufweisen.Furthermore, the clearing vehicle may have a coupling device for coupling the hollow body and the blown air device.

Bei einer Koppelvorrichtung handelt es sich um eine beliebe Vorrichtung, welche die Verbindung von Hohlkörper und Blasluftvorrichtung unterstützt. Beispielsweise hält die Koppelvorrichtung den Hohlkörper und die Blasluftvorrichtung zusammen, oder sie hält zumindest beide in Position, sodass die Blasluftverbindung gewährleistet bleibt, auch wenn das Fahrzeug während des Fahrens starke Erschütterungen erfährt.A coupling device is a device which facilitates the connection of Hollow body and blown air device supported. For example, the coupling device holds the hollow body and the blowing air device together, or at least holds both in position, so that the blast air connection remains ensured, even if the vehicle experiences strong shocks while driving.

In einer bevorzugten Ausführungsform ist die Koppelvorrichtung derart ausgestaltet, dass der Hohlkörper und die Blasluftverbindung mit Kraft der ersten Schwenkbewegung mittels der Koppelvorrichtung gegenseitig koppelbar sind, und mit Kraft der zweiten Schwenkbewegung gegenseitig entkoppelbar sind, d.h. aus der Kopplung gelöst werden.In a preferred embodiment, the coupling device is designed such that the hollow body and the blast air connection with the force of the first pivoting movement by means of the coupling device are mutually coupled, and with the force of the second pivoting movement are mutually decoupled, i. be released from the coupling.

Dies hat den Vorteil, dass mit der Kraft der Schwenkbewegung selbst die Kopplung erstellt werden kann. Es sind somit keine weiteren Manipulationen, beispielsweise von Hand oder mittels einem zusätzlichen Aktuator zur Betätigung der Kopplung notwendig. Solche Manipulationen sind aber dennoch möglich, falls die durch die Schwenkbewegung bereits erfolgte Kopplung durch eine zusätzliche Kopplung verstärkt werden soll.This has the advantage that even with the force of the pivoting movement, the coupling can be created. There are thus no further manipulations, for example by hand or by means of an additional actuator for actuating the coupling necessary. However, such manipulations are still possible if the already made by the pivoting movement coupling is to be reinforced by an additional coupling.

Mit Vorteil ist die Koppelvorrichtung am Traggestell angeordnet. Die Blasluftvorrichtung ist in ihren Schwenkbewegungen von der Koppelvorrichtung zumindest teilweise, insbesondere vollständig, geführt, und ein koppelbares Ende des Hohlkörpers ist an der Koppelvorrichtung angeordnet.Advantageously, the coupling device is arranged on the support frame. The blown air device is at least partially, in particular completely, guided in its pivoting movements by the coupling device, and a couplable end of the hollow body is arranged on the coupling device.

Da die Koppelvorrichtung am Traggestell angeordnet ist, schwenkt sie mit der Schwenkbewegung der Blasluftvorrichtung nicht mit. Die Blasluftvorrichtung schwenkt somit entlang der Koppelvorrichtung, welche die Schwenkbewegung führt.Since the coupling device is arranged on the support frame, it does not pivot with the pivoting movement of the blown air device. The blowing air device thus pivots along the coupling device, which guides the pivoting movement.

Die Koppelvorrichtung muss die Blasluftvorrichtung nicht zwingend über die gesamte Schwenkbewegung führen. Vorteilhaft wird die Schwenkbewegung allerdings an den Arbeitspositionen geführt, sodass der Hohlkörper und die Blasluftvorrichtung präzise aufeinander ausgerichtet sind zur Durchleitung der Blasluft.The coupling device does not necessarily have to guide the blown air device over the entire pivoting movement. Advantageously, however, the pivoting movement is performed at the working positions, so that the hollow body and the blast air device are precisely aligned with each other for the passage of the blast air.

Vorteilhaft weist die Koppelvorrichtung eine Führungsschiene auf, entlang welcher die Blasluftvorrichtung bewegbar angeordnet ist.Advantageously, the coupling device has a guide rail along which the blown air device is movably arranged.

Weiter kann die Koppelvorrichtung am Traggestell über einen Dreharm drehbar und in gekoppeltem Zustand mit der Blasluftvorrichtung mitschwenkend angeordnet sein, derart, dass die Blasluftvorrichtung durch den Dreharm und die Koppelvorrichtung geführt ist.Further, the coupling device may be rotatably mounted on the support frame via a rotating arm and mitschwenkend coupled state with the Blasluftvorrichtung, such that the Blasluftvorrichtung is guided by the rotary arm and the coupling device.

In einer besonderen Ausführungsform sind mindestens zwei Hohlkörperteile gegenüber dem Traggestell nicht schwenkbar angeordnet. Die Blasluftvorrichtung ist je nach eingestellter Arbeitsstellung, mit jeweils einem der mindestens zwei nicht schwenkbaren Hohlkörperteile in Blasluftverbindung.In a particular embodiment, at least two hollow body parts are not arranged pivotably relative to the support frame. The blown air device is, depending on the adjusted working position, with one of the at least two non-pivoting hollow body parts in blast air connection.

Mit anderen Worten ist die Blasluftverbindung zum Betrieb in einer ersten Arbeitsstellung mit einem ersten Hohlkörperteil verbunden und zum Betrieb in einer zweiten Arbeitsstellung mit einem zweiten Hohlkörperteil verbunden. Der erste und der zweite Hohlkörperteil haben somit unterschiedliche Auslässe, mit denen die Blasluftvorrichtung in Blasluftverbindung steht.In other words, the blown air connection for operation in a first working position is connected to a first hollow body part and connected for operation in a second working position with a second hollow body part. The first and the second hollow body part thus have different outlets with which the blown air device is in blown air connection.

Die beiden Hohlkörperteile können zusammengeführt werden und über einen gemeinsamen Abschnitt des Hohlkörpers mit dem Gebläse verbunden sein. D.h. nicht jeder einzelne Hohlkörperteil muss für sich alleine mit dem Gebläse verbunden sein, sondern ein einzelner vom Gebläse wegführender Hohlkörper kann beispielsweise in zwei Hohlkörperteile verzweigen.The two hollow body parts can be brought together and connected via a common portion of the hollow body with the blower. That Not every single hollow body part has to be connected to the fan alone, but a single hollow body leading away from the fan can, for example, branch into two hollow body parts.

Eine derartige Anordnung des Hohlkörpers hat den Vorteil, dass dieser relativ einfach ausgestaltet werden kann, weil die Hohlkörperteile statisch und nicht drehbar am Traggestell angeordnet sein müssen.Such an arrangement of the hollow body has the advantage that it can be configured relatively simply because the hollow body parts must be arranged static and non-rotatable on the support frame.

Mit Vorteil ist die Blasluftvorrichtung mit einem ersten Hohlkörperteil in Blasluftverbindung, falls die Kehrblasanordnung derart geschwenkt ist, dass auf eine erste Räumfahrzeugseite, insbesondere in Fahrtrichtung nach rechts, geräumt wird, und mit einem zweiten Hohlkörperteil in Blasluftverbindung, falls die Kehrblasanordnung derart geschwenkt ist, dass auf eine zweite Räumfahrzeugseite, insbesondere in Fahrtrichtung nach links, geräumt wird.Advantageously, the blown air device with a first hollow body part in Blasluftverbindung, if the Kehrblasanordnung is pivoted such that on a first Räumfahrzeugseite, especially in the direction of travel to the right, is vacated, and with a second hollow body part in Blasluftverbindung, if the Kehrblasanordnung is pivoted so that on a second Räumfahrzeugseite, especially in the direction of travel to the left, vacated.

Alternativ zu einer statischen Anordnung des Hohlkörpers kann auch vorgesehen sein, dass der Hohlkörper schwenkbar am Traggestell angeordnet ist. Die Koppelvorrichtung ist dabei derart ausgestaltet, dass der Hohlkörper mit den Schwenkbewegungen der Blasluftvorrichtung synchron mitschwenkend gekoppelt ist.Alternatively to a static arrangement of the hollow body can also be provided that the hollow body is pivotally mounted on the support frame. The coupling device is designed such that the hollow body is synchronously mitschwenkend with the pivoting movements of the blowing air device.

Insbesondere erstreckt sich die synchrone Schwenkbewegung über einen Winkelabschnitt von mindestens 45°, insbesondere von mindestens 60°, insbesondere von mindestens 90°.In particular, the synchronous pivoting movement extends over an angle section of at least 45 °, in particular of at least 60 °, in particular of at least 90 °.

Ein drehbar angeordneter Hohlkörper ist im Vergleich zu einem statisch angeordneten Hohlkörper zwar aufwändiger und komplexer auszugestalten, andererseits lässt sich im Schwenkbereich aber eine beliebige Anzahl von Positionen anfahren. Die Blasluftvorrichtung ist dadurch nicht nur an denjenigen Positionen, an welchen statische Hohlkörperteile angeordnet sind, mit diesen in Blasluftverbindung bringbar.A rotatably arranged hollow body is in comparison to a statically arranged hollow body, although complex and complex to design, on the other hand can be in the swivel range but approach any number of positions. The blown air device is thereby not only in those positions at which static hollow body parts are arranged, with these in blown air connection can be brought.

Mit Vorteil ist die Koppelvorrichtung derart ausgestaltet, dass die Blasluftvorrichtung über einen Winkelabschnitt von mindestens 60°, insbesondere von mindestens 75°, insbesondere von mindestens 90°, insbesondere von mindestens 135° in ihren Schwenkbewegungen geführt ist, insbesondere wobei die Blasluftvorrichtung über einen Winkelabschnitt von maximal 150°, insbesondere maximal 135°, insbesondere von maximal 110°, insbesondere von maximal 90°, insbesondere von maximal 60°, in ihren Schwenkbewegungen geführt ist.Advantageously, the coupling device is designed such that the blowing air device is guided over an angular section of at least 60 °, in particular of at least 75 °, in particular of at least 90 °, in particular of at least 135 ° in their pivotal movements, in particular wherein the blown air device over an angular section of a maximum of 150 °, in particular a maximum of 135 °, in particular of at most 110 °, in particular of at most 90 °, in particular of a maximum of 60 °, is guided in their pivoting movements.

Im Weiteren kann das Räumfahrzeug eine Anpressvorrichtung aufweisen, welche die mindestens eine Blasluftvorrichtung an die Koppelvorrichtung und/oder an den mindestens einen Hohlkörper bzw. Hohlkörperteil anpresst.In addition, the clearing vehicle may have a contact pressure device which connects the at least one blown air device to the coupling device and / or to the at least one hollow body or hollow body part presses.

Dies hat den Vorteil, dass sofern der Hohlkörper und die Blasluftvorrichtung nicht über eine steife Verbindung in einer Arbeitsposition miteinander gekoppelt sind, diese trotzdem zuverlässig in Blasluftverbindung verbleiben, auch wenn das Fahrzeug durch Unebenheiten auf der Fahrtstrecke starke Vibrationen erfährt.This has the advantage that, provided that the hollow body and the blown air device are not coupled together via a rigid connection in a working position, they still reliably remain in blown air connection, even if the vehicle experiences strong vibrations due to unevenness on the route.

In einer bevorzugten Ausführung ist die Kehrblasanordnung um einen Winkel von mindestens 90°, insbesondere von mindestens 110°, insbesondere von mindestens 130°, insbesondere von mindestens 135°, schwenkbar angeordnet, insbesondere wobei sich die Kehrblasanordnung bei einem Winkel 0° in der Transportstellung befindet, und bei einem Winkel zwischen 30°, insbesondere 45°, bis 135°, insbesondere 120°, in der Arbeitsstellung befindet.In a preferred embodiment, the Kehrblasanordnung by an angle of at least 90 °, in particular of at least 110 °, in particular of at least 130 °, in particular of at least 135 °, pivotally mounted, in particular wherein the Kehrblasanordnung is at an angle 0 ° in the transport position , And at an angle between 30 °, in particular 45 °, to 135 °, in particular 120 °, is in the working position.

Das Räumfahrzeug kann auf bekannte Weise ein Fahrzeug mit eigenem Fahrantrieb und insbesondere einem frontseitigen Schneepflug sein. Alternativ kann das Räumfahrzeug ein ziehbares Fahrzeug ohne eigenen Fahrantrieb sein, so dass es als Anhänger hinter einem Fahrzeug, insbesondere mit Schneepflug, mitgeführt wird.The clearing vehicle can be a vehicle with its own drive and in particular a front snowplough in a known manner. Alternatively, the clearing vehicle may be a towable vehicle without its own traction drive, so that it is carried along as a trailer behind a vehicle, in particular snowplough.

Der Erfindung liegt weiter die Aufgabe zu Grunde eine verbesserte Räumung, insbesondere eine Schneeräumung, mit einem Räumfahrzeug zu schaffen.The invention is further based on the object of providing an improved evacuation, in particular a snow removal, with a clearing vehicle.

Diese Aufgabe wird mit einem Verfahren gemäss dem unabhängigen Verfahrensanspruch gelöst.This object is achieved by a method according to the independent method claim.

Demgemäss weist das Räumfahrzeug eine Kehrblasanordnung auf, welche mindestens eine Blasluftvorrichtung umfasst.Accordingly, the clearing vehicle has a Kehrblasanordnung comprising at least one blown air device.

Die Kehrblasanordnung wird durch eine erste Schwenkbewegung aus einer Transportstellung in eine erste Arbeitsstellung geschwenkt, derart, dass die mindestens eine Blasluftvorrichtung mit mindestens einem Hohlkörper in Blasluftverbindung gebracht wird. Mit einer zweiten Schwenkbewegung wird die Kehrblasanordnung aus einer zweiten Arbeitsstellung in eine Transportstellung geschwenkt, derart, dass die Blasluftverbindung zwischen der mindestens einen Blasluftvorrichtung und dem mindestens einen Hohlkörper aufgehoben wird.The Kehrblasanordnung is pivoted by a first pivoting movement from a transport position to a first working position, such that the at least one blown air device is brought into blown air connection with at least one hollow body. With a second pivoting movement, the Kehrblasanordnung of a pivoted second working position in a transport position, such that the blast air connection between the at least one blown air device and the at least one hollow body is canceled.

Es ergeben sich dieselben Vorteile wie bereits beim unabhängigen Vorrichtungsanspruch beschrieben wurde.There are the same advantages as already described in the independent device claim.

Wege zur Ausführung der ErfindungWays to carry out the invention

In Fig. 1 wird ein Räumfahrzeug zur Räumung von Schnee dargestellt, wie es einem Fachmann aus dem Stand der Technik bekannt ist. Dieses weist einen Anhänger 1 und ein Zugfahrzeug 2 auf. Das Räumfahrzeug steht auf der Fläche, auf der sich der zu räumende Schnee befindet und die zum Beispiel eine Start- und Landebahn eines Flughafens ist. Ein solches Fahrzeug weist die bei Räumfahrzeugen üblichen Antriebe auf, die hier nicht weiter erläutert werden. Das Räumfahrzeug ist an der Front mit einem Schneepflug (nicht gezeigt) ausgerüstet, was hier ebenfalls nicht weiter erläutert wird, da dies dem Fachmann für Schneeräumfahrzeuge bekannt ist. Das Räumfahrzeug weist ein Traggestell 3 und eine Kehrblasanordnung 4 auf. Die Kehrblasanordnung 4 ist dabei um eine durch das Räumfahrzeug verlaufende Vertikalachse 5 schwenkbar angeordnet.In Fig. 1 A clearing vehicle for clearing snow is shown, as known to one skilled in the art. This has a trailer 1 and a towing vehicle 2. The clearing vehicle stands on the surface on which the snow to be cleared is located and which, for example, is an airport runway. Such a vehicle has the usual in sweeping vehicles drives, which are not further explained here. The clearing vehicle is equipped at the front with a snow plow (not shown), which is also not further explained here, since this is known to those skilled in snow removal vehicles. The clearing vehicle has a support frame 3 and a Kehrblasanordnung 4. The Kehrblasanordnung 4 is pivotally mounted about a vertical axis extending through the clearing vehicle 5.

Mit dem Räumfahrzeug soll der Boden möglichst sauber vom Schnee befreit werden. Derjenige Schnee, den der an der Frontseite des Räumfahrzeuges angeordnete Schneepflug nicht sauber vom Boden räumt, wird anschliessend durch die Kehrblasanordnung 4 vom Boden entfernt.With the clearing vehicle, the ground should be cleared of the snow as cleanly as possible. The snow that the snow plow arranged on the front side of the clearing vehicle does not cleanly clear from the ground is then removed from the ground by the sweeping blower arrangement 4.

Die Kehrblasanordnung 4 weist hierfür eine Kehrwalzenbürste 11, mit welcher der Schnee vom Boden gelöst bzw. aufgeputzt und aufgewirbelt wird, und eine Blasluftvorrichtung 8, mit welcher der aufgewirbelte Schnee zur Seite geblasen wird, auf. Zum Versorgen der Blasluftvorrichtung 8 mit Blasluft ist am Traggestell 3 ein Gebläse 6 angeordnet, welches Blasluft über zwei Teile eines Hohlkörpers 7 zur Blasluftvorrichtung 8 befördert.The Kehrblasanordnung 4 has for this purpose a brush roller brush 11, with which the snow is detached from the ground or cleaned up and whirled, and a blown air device 8, with which the fluidized snow is blown to the side on. For supplying the blown air device 8 with blown air on the support frame 3, a fan 6 is arranged, which conveys blown air over two parts of a hollow body 7 to the blown air device 8.

Die Kehrblasanordnung 8 ist in Fig. 1 in eine Arbeitsstellung geschwenkt, sodass in Fahrtrichtung (Pfeil 9) nach rechts (Pfeil 10) der Schnee geräumt und geblasen werden kann. Dabei sind die zwei Hohlkörperteile des Hohlkörpers 7 mit der Blasluftvorrichtung 8 gekoppelt, um die vom Gebläse erzeugte Blasluft der Blasluftvorrichtung 8 zuzuführen.The Kehrblasanordnung 8 is in Fig. 1 pivoted into a working position, so that in the direction of travel (arrow 9) to the right (arrow 10), the snow can be cleared and blown. Here are the two hollow body parts of the hollow body 7 is coupled to the blown air device 8 in order to supply the blown air generated by the fan to the blown air device 8.

Die Kehrblasanordnung 4 ist in eine Transportstellung schwenkbar, in welcher die Kehrwalzenbürste 11 mit ihrer Drehachse im Wesentlichen in Längsrichtung des Räumfahrzeuges liegend angeordnet wird. Die Transportstellung ist beispielsweise nützlich für den Transport über weite Fahrtwege, insbesondere über schmale Strassen, oder um das Räumfahrzeug platzsparend in einer Garage abzustellen.The Kehrblasanordnung 4 is pivotable in a transport position in which the brush roller brush 11 is disposed with its axis of rotation lying substantially in the longitudinal direction of the clearing vehicle. The transport position, for example, useful for transport over long distances, especially on narrow streets, or to save the clearing vehicle to save space in a garage.

Bei einem in Fig. 1 dargestellten, aus dem Stand der Technik bekannten Räumfahrzeug müssen die Hohlkörperteile des Hohlkörpers 7 von den Blasluftvorrichtungen 8 entkoppelt werden, um die Kehrblasanordnung 4 in die Transportstellung zu schwenken.At an in Fig. 1 illustrated, known from the prior art Räumfahrzeug the hollow body parts of the hollow body 7 must be decoupled from the Blasluftvorrichtungen 8 to pivot the Kehrblasanordnung 4 in the transport position.

In den weiteren Figuren werden zwei unterschiedliche Ausführungen eines verbesserten Räumfahrzeuges dargestellt, bei welchen die Kehrblasanordnung 4 zwischen Transportstellung und Arbeitsstellung möglichst einfach geschwenkt werden kann.In the other figures, two different embodiments of an improved clearing vehicle are shown, in which the Kehrblasanordnung 4 can be pivoted as easy as possible between transport position and working position.

In den Fig. 2 bis 5 wird die erste Ausführungsform des Räumfahrzeuges dargestellt, wobei diese statische Hohlkörperteile des Hohlkörpers 7 aufweist, d.h. die Hohlkörperteile bzw. der Hohlkörper 7 drehen nicht mit der Schwenkbewegung der Kehrblasanordnung mit. In den Fig. 6 bis 8 weist das Räumfahrzeug in einer zweiten Ausführungsform Hohlkörperteile des Hohlkörpers 7 auf, welche mit der Schwenkbewegung der Kehrblasanordnung 4 mitgeschwenkt werden können.In the Fig. 2 to 5 the first embodiment of the clearing vehicle is shown, wherein this has static hollow body parts of the hollow body 7, ie the hollow body parts or the hollow body 7 do not rotate with the pivoting movement of the Kehrblasanordnung. In the Fig. 6 to 8 has the clearing vehicle in a second embodiment, hollow body parts of the hollow body 7, which can be swung with the pivoting movement of the Kehrblasanordnung 4.

In den Fig. 2 und 3 ist das Räumfahrzeug der ersten Ausführungsform in der Transportstellung dargestellt. In der Transportstellung ist die Kehrblasanordnung 4 mit der Kehrwalzenbürste 11 und der Blasluftvorrichtung 8 parallel zur Fahrtrichtung 9 angeordnet, bzw. die Längsachse der Kehrwalzenbürste liegt im Wesentlichen koaxial zur Längsachse des Traggestells 3, sodass das Räumfahrzeug in seiner seitlichen Ausdehnung möglichst schmal ist.In the FIGS. 2 and 3 the clearing vehicle of the first embodiment is shown in the transport position. In the transport position the Kehrblasanordnung 4 is arranged with the brush roller brush 11 and the Blasluftvorrichtung 8 parallel to the direction of travel 9, or the longitudinal axis of the brush roller brush is substantially coaxial with the longitudinal axis of the support frame 3, so that the Clearing vehicle is as narrow as possible in its lateral extent.

In der Transportstellung stehen die Hohlkörperteile des Hohlkörpers 7 und die Blasluftvorrichtungen 8 nicht in Blasluftverbindung. Die Hohlkörperauslässe 12, d.h. die koppelbaren Enden der Hohlkörperteile des Hohlkörpers 7, sind nicht mit den Blasluftvorrichtungseinlässen 13, d.h. mit den koppelbaren Enden der Blasluftvorrichtung 8, verbunden.In the transport position, the hollow body parts of the hollow body 7 and the Blasluftvorrichtungen 8 are not in blown air. The hollow body outlets 12, i. the coupled ends of the hollow body parts of the hollow body 7 are not connected to the blowing air device inlets 13, i. with the coupling ends of the blowing air device 8, connected.

Zur Versorgung der Blasluftvorrichtung führen zwei Hohlkörperteile des Hohlkörpers 7 vom Gebläse 6 weg bzw. der Hohlkörper 7 verzweigt in zwei separate Hohlkörperteile bzw. Hohlkörperstränge, sodass insgesamt vier Hohlkörperauslässe 12 vorhanden sind. In Fahrtrichtung 9 gesehen sind zwei Hohlkörperauslässe 12 links und zwei Hohlkörperauslässe rechts vom Traggestell 3 angeordnet. In dieser Ausführungsform sind sämtliche Teile des Hohlkörpers 7 gegenüber dem Traggestell 3 statisch angeordnet und werden nicht mit der Kehrblasanordnung um die Vertikalachse 5 mitgeschwenkt.To supply the blown air device two hollow body parts of the hollow body 7 lead away from the fan 6 and the hollow body 7 branches into two separate hollow body parts or hollow body strands, so that a total of four hollow body outlets 12 are present. As seen in the direction of travel 9, two hollow body outlets 12 on the left and two hollow body outlets on the right of the support frame 3 are arranged. In this embodiment, all parts of the hollow body 7 are arranged statically relative to the support frame 3 and are not pivoted about the vertical axis 5 with the Kehrblasanordnung.

Im Weiteren weist das Räumfahrzeug eine Koppelvorrichtung 14 auf, welche die Blasluftverbindung zwischen Hohlkörper 7 und Blasluftvorrichtung 8 unterstützt. In der vorliegenden Ausführungsform weist die Koppelvorrichtung 14 eine Führungsschiene 15 auf, welche die Blasluftvorrichtungen 8 bzw. die Blasluftvorrichtungseinlässe 13 in ihren Bewegungen führt, sodass diese bei Erreichen der Arbeitsstellungen mit den Hohlkörperteilen des Hohlkörpers 7 präzise in Blasluftverbindung stehen.Furthermore, the clearing vehicle has a coupling device 14, which supports the blown air connection between the hollow body 7 and blown air device 8. In the present embodiment, the coupling device 14 has a guide rail 15, which guides the Blasluftvorrichtungen 8 and the Blasluftvorrichtungseinlässe 13 in their movements, so that they are precisely in blasluftverbindung on reaching the working positions with the hollow body parts of the hollow body 7.

Aus der Transportstellung kann die Kehrblasanordnung 4 um die Vertikalachse 5 in eine erste Arbeitsstellung geschwenkt werden (Pfeil 16). In den Fig. 4 und 5 ist das Räumfahrzeug in der ersten Arbeitsstellung dargestellt. Dabei wird wie in Fig. 1 der Schnee in Fahrtrichtung (Pfeil 9) nach rechts (Pfeil 10) weggeräumt. Hierfür wurde die Kehrblasanordnung 4 von der Transportstellung um einen Winkel 17 von 45° in Gegenuhrzeigerrichtung (Pfeil 16) geschwenkt. Wie in Fig. 5 sichtbar, steht die Blasluftvorrichtung 8 mit dem Hohlkörper 7 in der ersten Arbeitsstellung in Blasluftverbindung. Durch die Führungsschiene 15 wurde die Blasluftvorrichtung 8 präzise an einen ersten Hohlkörperauslass 121 herangeführt. Auf der dem Traggestell 3 gegenüberliegenden Seite steht die Blasluftvorrichtung 8 ebenfalls mit dem Hohlkörper 7 an einem ersten Hohlkörperauslass 121 in Blasluftverbindung.From the transport position, the Kehrblasanordnung 4 can be pivoted about the vertical axis 5 in a first working position (arrow 16). In the 4 and 5 the clearing vehicle is shown in the first working position. It will be like in Fig. 1 the snow in the direction of travel (arrow 9) to the right (arrow 10) cleared away. For this purpose, the Kehrblasanordnung 4 of the Transport position by an angle 17 of 45 ° in the counterclockwise direction (arrow 16) pivoted. As in Fig. 5 Visible, is the Blasluftvorrichtung 8 with the hollow body 7 in the first working position in Blasluftverbindung. By the guide rail 15, the blown air device 8 has been precisely brought to a first hollow body outlet 121. On the opposite side of the support frame 3, the blown air device 8 is also connected to the hollow body 7 at a first hollow body outlet 121 in Blasluftverbindung.

Würde die Kehrblasanordnung um weitere 90° im Gegenuhrzeigersinn gedreht werden, so stünden die Blasluftvorrichtungen 8 und der Hohlkörper 7 an den zweiten Hohlkörperauslässen 122 in einer zweiten Arbeitsstellung in Blasluftverbindung, sodass der Schnee nach links weggeblasen würde. In diesem Fall wäre die Blasluftvorrichtung 8 ausgehend von der Transportstellung um insgesamt 135° in Gegenuhrzeigerrichtung geschwenkt worden. Bei der Schwenkbewegung von der ersten Arbeitsstellung zur zweiten Arbeitsstellung bewegt sich die Blasluftvorrichtung 8 entlang der Führungsschiene 15, wobei die Blasluftverbindung mit dem ersten Hohlkörperauslass 121 aufgelöst wird, und eine Blasluftverbindung mit dem zweiten Hohlkörperauslass 122 hergestellt wird.If the Kehrblasanordnung would be rotated by a further 90 ° in the counterclockwise direction, so would the Blasluftvorrichtungen 8 and the hollow body 7 at the second Hohlkörperauslässen 122 in a second working position in blown air, so that the snow would blow away to the left. In this case, the blown air device 8 would have been pivoted from the transport position by a total of 135 ° in the counterclockwise direction. During the pivoting movement from the first working position to the second working position, the blowing air device 8 moves along the guide rail 15, wherein the blown air connection with the first hollow body outlet 121 is dissolved, and a blown air connection with the second hollow body outlet 122 is established.

Im Weiteren weist das Räumfahrzeug eine Anpressvorrichtung 18 auf, mit welcher die Blasluftvorrichtung 8 an die Führungsschiene 15 bzw. den Hohlkörper 7 gedrückt wird.In addition, the clearing vehicle has a contact pressure device 18 with which the blown air device 8 is pressed against the guide rail 15 or the hollow body 7.

Beginnend mit Fig. 6 wird nun eine alternative Ausführungsform des Räumfahrzeugs dargestellt. Dieses weist einen Hohlkörper 7 mit Hohlkörperteilen auf, welche nicht mehr statisch am Traggestell 3 angeordnet sind, sondern mit der Schwenkbewegung der Kehrblasanordnung zumindest teilweise mitgeschwenkt werden können.Starting with Fig. 6 Now an alternative embodiment of the clearing vehicle is shown. This has a hollow body 7 with hollow body parts, which are no longer arranged statically on the support frame 3, but at least partially can be pivoted with the pivoting movement of the Kehrblasanordnung.

In Fig. 6 ist das Räumfahrzeug wie in den Fig. 2 und 3 in der Transportstellung dargestellt. Die Blasluftvorrichtung 8 und die Hohlkörperteile des Hohlkörpers 7 stehen nicht in Blasluftverbindung. Der Hohlkörper 7 wird dabei über einen Dreharm 19 in Position gehalten.In Fig. 6 is the clearing vehicle like in the FIGS. 2 and 3 shown in the transport position. The Blowing air device 8 and the hollow body parts of the hollow body 7 are not in blast air connection. The hollow body 7 is held by a pivot arm 19 in position.

Der Dreharm 19 weist an seinen äusseren Enden jeweils einen Mitnehmer 20 mit einer Auffangvorrichtung 24 auf. Während der Schwenkbewegung der Kehrblasanordnung von der Transportstellung in die erste Arbeitsstellung fängt die Auffangvorrichtung 24 die Blasluftvorrichtung auf, sodass der Hohlkörper 7 und die Blasluftvorrichtung 8 in Blasluftverbindung gebracht werden.The rotary arm 19 has at its outer ends in each case a driver 20 with a collecting device 24. During the pivoting movement of the Kehrblasanordnung from the transport position to the first working position, the collecting device 24 catches the blown air device, so that the hollow body 7 and the blown air device 8 are brought into blown air.

Ausgehend von der ersten Arbeitsstellung, welche in den Fig. 7 und 8 dargestellt ist, kann die Kehrblasanordnung wiederum über weitere 90° in Gegenuhrzeigerrichtung in eine zweite Arbeitsstellung geschwenkt werden. Hierbei überträgt der Mitnehmer 20 die Kraft der Schwenkbewegung der Kehrblasanordnung in eine erste Richtung (Pfeilrichtung 21) auf die Hohlkörperteile des Hohlkörpers 7, sodass die Hohlkörperteile synchron mit der Blasluftvorrichtung 8 mitschwenken.Starting from the first working position, which in the FIGS. 7 and 8 is shown, the Kehrblasanordnung can be pivoted in turn over 90 ° in a counterclockwise direction in a second working position. Here, the driver 20 transmits the force of the pivoting movement of the Kehrblasanordnung in a first direction (arrow 21) on the hollow body parts of the hollow body 7, so that the hollow body parts pivot synchronously with the Blasluftvorrichtung 8.

Mit der Schwenkbewegung in die erste Richtung (Pfeilrichtung 21) wird eine Rückstellvorrichtung 23 gespannt. Diese bewegt den Hohlkörper 7 bzw. dessen Teile in eine zweite Richtung (Pfeilrichtung 22), welche der ersten Richtung entgegengesetzt ist, sobald die Kehrblasanordnung in Pfeilrichtung 22 zurückgeschwenkt wird. Damit der Hohlkörper 7 synchron mitschwenken kann, ist er aus flexiblen Schläuchen gebildet.With the pivoting movement in the first direction (arrow 21), a return device 23 is tensioned. This moves the hollow body 7 or its parts in a second direction (arrow 22), which is opposite to the first direction as soon as the Kehrblasanordnung is pivoted back in the direction of arrow 22. So that the hollow body 7 can pivot synchronously, it is formed from flexible hoses.

Der Vorteil eines flexiblen Hohlkörpers 7 liegt darin, dass nicht nur zwei Arbeitsstellungen wie in der ersten Ausführungsform möglich sind, sondern dass die Kehrblasanordnung in einen beliebigen Winkel zwischen der ersten Arbeitsstellung und der zweiten Arbeitsstellung geschwenkt werden kann.The advantage of a flexible hollow body 7 is that not only two working positions as in the first embodiment are possible, but that the Kehrblasanordnung can be pivoted in any angle between the first working position and the second working position.
