Abstract

An attachment (1) for attaching to the front of a road-sweeping machine (2) has a frame (3) which is guided by means of supporting rollers (4) over the surface (5) of a road, in particular of a road tunnel which has let into its surface reflectors (8) which have to be cleaned. For this purpose, a cleaning brush (9) with its axis of rotation (10) parallel to the direction of travel is arranged in a downwardly open housing (11) inside of which are arranged water-spraying nozzles for water mixed with washing fluid. The housing (11) for the cleaning brush (9) is suspended by means of guide rollers (14) on rails (13) arranged transversely with respect to the direction of travel to allow the to-and-fro movement of the housing by means of a hydraulic cylinder (11a), so that particularly the reflector surfaces of the reflector (8) which point in the direction of travel are cleaned by the transverse motion and high-speed rotation of the brush. A shower arrangement (15) disposed behind the cleaning brush in the direction of travel comprises, inside a housing, water-spraying nozzles for rinsing away the washing fluid. Located behind the shower arrangement in the direction of travel is a blowing nozzle (17) through which drying air is blown, a fan arranged on the road-sweeping machine (2) supplying the air via a line (19). The apparatus permits a rapid cleaning operation over long tunnel sections by means of only one... Original abstract incomplete. <IMAGE>

Description

Die Erfindung betrifft eine Einrichtung zum Reinigen von in der Bodenfläche von Verkehrswegen parallel zur Fahrtrichtung in Abständen voneinander angeordneten Markierungen, insbesondere Reflektoren. Derartige Reflektoren besitzen in Fahrtrichtung vorderseitig und rückseitig etwas schräg stehende Reflektorflächen, die nach einer gewissen Zeit verschmutzt sind, besonders wenn sie in einem Strassentunnel angeordnet sind, in dem die Verschmutzung durch Strassenstaub und Abgase besonders intensiv ist und die Reflektoren nie mit Regenwasser in Berührung kommen. Verschmutzte Reflektoren erfüllen ihre Funktion nicht mehr, was gerade in einem Tunnel eine erhöhte Gefährdung der Verkehrssicherheit darstellt und bei einem Unfall Haftungsfragen auslöst. Reflektoren dieser Art sind entweder auf der Mittelleitlinie oder an den Strassenrändern oder auch auf einem durch den ganzen Tunnel sich erstreckenden erhöhten Seitenbord in regelmässigen Abständen angeordnet.The invention relates to a device for cleaning markings, in particular reflectors, arranged in the floor area of traffic routes parallel to the direction of travel at intervals. Such reflectors have reflector surfaces that are slightly sloping in the direction of travel on the front and rear, which become dirty after a certain time, especially if they are arranged in a road tunnel in which the pollution from street dust and exhaust gases is particularly intense and the reflectors never come into contact with rainwater . Dirty reflectors no longer fulfill their function, which in particular in a tunnel poses an increased risk to traffic safety and triggers questions of liability in the event of an accident. Reflectors of this type are arranged either on the central guideline or on the side of the road or on an elevated sideboard that extends through the entire tunnel at regular intervals.

Herkömmliche Strassenkehrmaschinen besitzen rotierende Tellerbürsten, mit denen dieses Reinigungsproblem nicht zu lösen ist, sodass nur die Reinigung von Hand als Alternative bleibt, weil der in einem Tunnel durch Einwirkung von Abgasen wie Diesel-Russpartikel hervorgerufene Schmutzbelag besonders stark haftet. Bei den vorhandenen viele kilometerlangen Strassentunnel ist eine Reinigung von Hand schon aus gesundheitlichen Gründen wegen des langen Aufenthalts in den Abgasen nicht möglich.Conventional street sweepers have rotating disc brushes that cannot be used to solve this cleaning problem, so that only manual cleaning remains as an alternative because the dirt deposit in a tunnel caused by exhaust gases such as diesel soot particles adheres particularly strongly. In the existing many kilometer-long road tunnels, cleaning by hand is not possible for health reasons because of the long stay in the exhaust gases.

Der Erfindung lag daher die Aufgabe zugrunde, eine Einrichtung zum maschinellen Reinigen von im Bodenbereich vorhandenen Markierungen wie insbesondere Reflektoren zu schaffen, mit deren Hilfe die Reinigungsarbeit speditiv und sehr gründlich durchführbar ist und von einer in einem Fahrzeug geschützt sitzenden Bedienungsperson ausgeführt werden kann. Zur Lösung dieser Aufgabe weist die Einrichtung die Merkmale nach Anspruch 1 auf. Man verwendet für diesen Zweck eine Strassenkehrmaschine, die alle notwendigen Einrichtungen wie Wassertank sowie Gebläse zum Trocknen und Antriebseinheiten für die Hydraulik etc. besitzt. Die Einrichtung für die spezielle Reinigungsaufgabe ist daher ein Anbaugerät an einem Fahrzeug, das auch für andere Zwecke einsetzbar ist.The invention was therefore based on the object of providing a device for machine cleaning of markings present in the floor area, in particular reflectors, with the aid of which the cleaning work can be carried out quickly and very thoroughly and can be carried out by an operator sitting in a protected vehicle. To achieve this object, the device has the features of claim 1. A street sweeper is used for this purpose, which has all the necessary equipment such as a water tank, blowers for drying and drive units for the hydraulics, etc. The device for the special cleaning task is therefore an attachment to a vehicle that can also be used for other purposes.

Ein Ausführungsbeispiel des Erfindungsgegenstandes wird nachfolgend anhand der Zeichnungen näher beschrieben. Es zeigen:

  • Fig. 1 eine Vorderansicht der Einrichtung an einer Strassenkehrmaschine;
  • Fig. 2 die Einrichtung in Draufsicht von oben;
  • Fig. 3 die Einrichtung in schaubildlicher Darstellung;
  • Fig. 4 bis 6 eine abgewandelte Ausführungsform, in entsprechenden Ansichten wie Fig. 1 bis 3.
An embodiment of the subject matter of the invention is described below with reference to the drawings. Show it:
  • Figure 1 is a front view of the device on a road sweeper.
  • Figure 2 shows the device in plan view from above.
  • Figure 3 shows the device in a diagram.
  • 4 to 6 a modified embodiment, in corresponding views as Fig. 1 to 3rd

Die Einrichtung weist ein Anbaugerät 1 auf, das an einer Strassenkehrmaschine 2 frontseitig auswechselbar befestigt ist. Das Anbaugerät 1 weist ein mehrteiliges Gestell 3 auf, das in der Arbeitsstellung mittels vier Stützrollen 4 auf der Bodenfläche 5 des Verkehrsweges abgestützt ist. Für den Transport auf der Strasse lässt sich der in der Zeichnung linke Teil 3a des Gestells 3 mit den Stützrollen 4 mit Hilfe eines Hydraulikzylinders 6 anheben. Der in der Zeichnung rechte Gestellteil 3b ist mit Hilfe von zwei parallelen Trägern 3c an der Strassenkehrmaschine 2 derart angelenkt, dass ein dadurch gebildetes Gelenkparallelogramm eine Verschwenkung des gesamten Gestells 3 in einer horizontalen Ebene von der in den Zeichnungen gezeigten Arbeitsstellung nach rechts bis mittig vor die Strassenkehrmaschine 2 ermöglicht, damit diese zum Einsatzort fahren kann. Die seitliche Verschwenkung erfolgt durch einen Hydraulikzylinder 7, dessen eines Ende an der Strassenkehrmaschine und dessen anderes Ende an einem der Träger 3c angelenkt ist.The device has an attachment 1, which is attached to the front of a street sweeper 2 replaceably. The attachment 1 has a multi-part frame 3, which is supported in the working position by means of four support rollers 4 on the floor surface 5 of the traffic route. For transport on the road, the left part 3a of the frame 3 with the support rollers 4 in the drawing can be raised with the aid of a hydraulic cylinder 6. The frame part 3b on the right in the drawing is articulated to the street sweeper 2 with the aid of two parallel supports 3c in such a way that an articulated parallelogram formed thereby pivots the entire frame 3 in a horizontal plane from that in FIG Drawings shown working position right to center in front of the street sweeper 2 allows so that it can drive to the site. The lateral pivoting takes place by means of a hydraulic cylinder 7, one end of which is articulated on the street sweeper and the other end of which is articulated on one of the carriers 3c.

In der Arbeitsstellung laufen die Stützrollen 4 auf der Bodenfläche 5,.die in diesem Fall ein höherliegendes Seitenbord innerhalb eines Strassentunnels ist. In diesem Seitenbord sind in Fahrtrichtung in regelmässigen Abständen voneinander Reflektoren 8 angeordnet, deren über der Bodenfläche liegende Reflektorflächen gereinigt werden sollen. Dies erfolgt durch eine hochtourig drehende Reinigungsbürste 9, deren Drehachse 10 parallel zur Fahrtrichtung der Strassenkehrmaschine 2 angeordnet ist. Bei dieser Arbeitsweise erfasst die Reinigungsbürste vor allem die beiden in Fahrtrichtung zeigenden Reflektorflächen des Reflektors 8. Die Reinigungsbürste 9 ist von einem zur Unterseite hin offenen Gehäuse 11 umschlossen, in welchem innenseitig eine Anzahl von Düsen 12 in Reihe hintereinander und parallel zur Drehachse 10 angeordnet sind, durch welche Düsen eine Mischung aus Wasser und Waschflüssigkeit unter Druck austritt. Die Waschflüssigkeit ist dem Wasser dosiert zugesetzt. Gleichzeitig wird das die Reinigungsbürste 9 mit Ausnahme an der Unterseite umschliessende Gehäuse 11, in welchem die Reinigungsbürste drehbar gelagert ist, quer zur Fahrtrichtung in der Zeichnung von links nach rechts bewegt. Zu diesem Zweck ist das Gehäuse 11 an einer schienenartigen Aufhängung 13 mittels Laufrollen 14 hin- und herbeweglich gehalten. Die schienenartige Aufhängung 13 besteht aus zwei Rohren oberhalb der beiden Stirnenden des Gehäuses 11 und bei jedem dieser Rohre 13 bilden zwei oben auf dem Rohr laufende Laufrollen 14 und zwei gegen die Unterseite des Rohrs anliegende Laufrollen 14 eine Führung für das Gehäuse 11 , um das Gewicht des Gehäuses einerseits und den nach oben gerichteten Gegendruck der gegen die Bodenfläche angedrückten Reinigungsbürste 9 aufzunehmen. Die zweite Endstellung des nach links und rechts bewegbaren Gehäuses 11 ist durch gestrichelt gezeichnete Laufrollen markiert. Während der Reinigung eines Reflektors 8 bewegt sich das Gehäuse 11 mittels eines Hydraulikzylinders 11a einmal von der Aussen- zur Innenseite und kehrt dann in die Ausgangsstellung zurück, um beim nächsten Reflektor den Bewegungszyklus zu wiederholen.In the working position, the support rollers 4 run on the floor surface 5, which in this case is a higher side board within a road tunnel. In this side board, reflectors 8 are arranged at regular intervals from one another in the direction of travel, the reflector surfaces of which are to be cleaned above the floor surface. This is done by a high-speed rotating cleaning brush 9, the axis of rotation 10 of which is arranged parallel to the direction of travel of the street sweeper 2. In this mode of operation, the cleaning brush mainly detects the two reflector surfaces of the reflector 8 pointing in the direction of travel. The cleaning brush 9 is enclosed by a housing 11 which is open towards the underside and in which a number of nozzles 12 are arranged in series one behind the other and parallel to the axis of rotation 10 through which nozzles a mixture of water and washing liquid emerges under pressure. The washing liquid is added to the water in doses. At the same time, the housing 11 enclosing the cleaning brush 9, with the exception of the underside, in which the cleaning brush is rotatably mounted, is moved transversely to the direction of travel in the drawing from left to right. For this purpose, the housing 11 is held on a rail-like suspension 13 so that it can move back and forth by means of rollers 14. The rail-like suspension 13 consists of two tubes above the two ends of the housing 11 and each of these tubes 13 form two rollers 14 running on top of the tube and two rollers 14 resting against the underside of the tube, a guide for the Housing 11 to accommodate the weight of the housing on the one hand and the upward counter pressure of the cleaning brush 9 pressed against the bottom surface. The second end position of the housing 11, which can be moved to the left and right, is marked by rollers shown in broken lines. During the cleaning of a reflector 8, the housing 11 moves once from the outside to the inside by means of a hydraulic cylinder 11a and then returns to the starting position in order to repeat the movement cycle for the next reflector.

In Fahrtrichtung hinter dem Gehäuse 11 mit der Reinigungsbürste 9 ist an dem Gestellteil 3a ein nach unten offenes Gehäuse 15 mit einer Anzahl von an eine Druckwasserleitung angeschlossenen Wasserdüsen 16 als Duscheinrichtung angeordnet, um die Waschflüssigkeit von den Reflektoren 8 und der Umgebung wegzuspülen. Die Flüssigkeit gelangt von der erhöhten Bordkante auf die Fahrbahn herunter, wo sie von der Strassenkehrmaschine mit den dafür geeigneten bekannten Einrichtungen aufgenommen wird.In the direction of travel behind the housing 11 with the cleaning brush 9, a downwardly open housing 15 with a number of water nozzles 16 connected to a pressurized water line is arranged as a shower device on the frame part 3a in order to wash away the washing liquid from the reflectors 8 and the surroundings. The liquid comes down from the raised beltline onto the road, where it is picked up by the street sweeper with the known devices suitable for it.

In Fahrtrichtung hinter der Duscheinrichtung 15, 16 befindet sich an dem Gestellteil 3a ferner eine schräg nach unten gegen die Bodenfläche gerichtete Blasdüse 17 mit einem breiten trichterförmigen Öffnungsspalt 18, durch den Luft zum Trocknen der vorher nass behandelten Flächen geblasen wird, welche Luft über eine flexible Leitung 19 von einem in der Strassenkehrmaschine 2 angeordneten und nicht dargestellten Gebläse zugeführt wird.In the direction of travel behind the shower device 15, 16 there is also on the frame part 3a an obliquely downward directed blow nozzle 17 with a wide funnel-shaped opening gap, through which air is blown to dry the previously wet-treated surfaces, which air is flexible Line 19 is supplied from a blower arranged in the street sweeper 2 and not shown.

Damit das in der Arbeitsstellung auf seinen Stützrollen 4 laufende Gestell 3 immer genau einer Linie folgt, auf der alle Reflektoren 8 liegen, welche Linie bei einer Strassenkurve nicht gerade verläuft, ist am Gestell 3 eine Spur- und Abstandshalteeinrichtung in Form eines an einem am Gestell befestigten Arm 20 drehbar gelagerten Rades 21 angeordnet, welches an der Kante des erhöhten seitlichen Bords 5 der Fahrbahn abwälzt, wodurch das Gestell immer auf der richtigen Spur bleibt.So that the frame 3 running on its support rollers 4 in the working position always follows exactly one line on which all reflectors 8 lie, which line does not run straight on a road curve, on the frame 3 there is a tracking and spacing device in the form of one on the frame attached arm 20 rotatable mounted wheel 21 arranged, which rolls on the edge of the raised side flange 5 of the roadway, whereby the frame always remains on the right track.

Wenn die Reflektoren 8 in Fahrtrichtung in einem grösseren Abstand von mehreren Metern voneinander angeordnet sind, kann während der zwischen den Reflektoren zurückzulegenden Fahrstrecke der Arbeitszyklus der Reinigungsbürste 9 kurzzeitig unterbrochen sein und beginnt jedesmal neu, wenn ein am vorderen Ende des Gestells angeordneter Fühlerstab 22 gegen einen Reflektor 8 anfährt und dadurch mit bekannten Mitteln über elektrische Kontakte einen neuen Arbeitszyklus auslöst, in welchem die Reinigungsbürste unter Wasserzugabe rotiert und einmal nach links und in die Ausgangsstellung wieder zurückbewegt wird.If the reflectors 8 are arranged at a greater distance of several meters from one another in the direction of travel, the working cycle of the cleaning brush 9 can be briefly interrupted during the travel distance to be covered between the reflectors and starts again each time a sensor rod 22 arranged at the front end of the frame against one Reflector 8 starts and thereby triggers a new working cycle by known means via electrical contacts, in which the cleaning brush rotates with the addition of water and is moved once to the left and back into the starting position.

Wie bereits erwähnt, sind auf der Strassenkehrmaschine 2 alle für den Betrieb der Reinigungsvorrichtung notwendigen Einrichtungen wie ein Wasserreservoir einschliesslich Pumpe, Behälter und Dosiereinrichtungen für die Waschflüssigkeit sowie eine Ölhydraulik installiert, was nicht weiter dargestellt ist. Für die Betätigung der Reinigungsvorrichtung sind an der Frontseite der Strassenkehrmaschine 2 die notwendigen Leitungen mittels Kupplungen angeschlossen, und zwar Öldruckleitungen 25, die zu einem die Reinigungsbürste 9 antreibenden Ölmotor 26 führen, ferner Öldruckleitungen 27 für einen kleinen Betätigungszylinder 28, mit welchem die Stellung des Spurrades 21 verändert werden kann, ferner Öldruckleitungen 29 für den Hubzylinder 11a, welcher das Gehäuse 11 mit der Reinigungsbürste 9 hin- und herbewegt, sowie ferner Öldruckleitungen 30 für den Hubzylinder 6 zum Anheben des Gestellteils 3a, sowie schliesslich Öldruckleitungen 31 für den Hubzylinder 7 für die seitliche Schwenkbewegung des gesamten Anbaugerätes. Alle Öldruckleitungen sind als Bündel zusammengefasst an die Strassenkehrmaschine 2 angeschlossen. Von dieser führt ferner eine Wasserleitung 32 zu den in dem Gehäuse 11 innenseitig angeordneten und miteinander in Verbindung stehenden Wasserdüsen 12, sowie ferner eine weitere Wasserleitung 33 zu den in dem Gehäuse 15 der Duscheinrichtung befindlichen Spritzdüsen 16.As already mentioned, all devices necessary for the operation of the cleaning device, such as a water reservoir including a pump, containers and metering devices for the washing liquid, and an oil hydraulic system are installed on the street sweeper 2, which is not shown in any more detail. For the actuation of the cleaning device, the necessary lines are connected by means of couplings to the front of the street sweeper 2, namely oil pressure lines 25, which lead to an oil motor 26 driving the cleaning brush 9, and also oil pressure lines 27 for a small actuating cylinder 28, with which the position of the track wheel 21 can be changed, further oil pressure lines 29 for the lifting cylinder 11a, which moves the housing 11 back and forth with the cleaning brush 9, and furthermore oil pressure lines 30 for the lifting cylinder 6 for lifting the frame part 3a, and finally oil pressure lines 31 for the lifting cylinder 7 for the lateral pivoting movement of the entire attachment. All oil pressure lines are combined as a bundle to the street sweeper 2 connected. From this, a water line 32 also leads to the water nozzles 12, which are arranged on the inside in the housing 11 and are connected to one another, and also a further water line 33 to the spray nozzles 16 located in the housing 15 of the shower device.

Bei einer abgewandelten Ausführungsform der vorstehend beschriebenen Einrichtung ist das Gehäuse 11 mit der Reinigungsbürste 9 nicht hin- und herbeweglich sondern feststehend angeordnet, um eine solche Maschine beispielsweise zum Reinigen von auf einer Strasenmarkierungslinie angeordneten Reflektoren zu verwenden. Diese in Fig. 4 bis 6 dargestellte Einrichtung ist in ihrem Aufbau gleich ausgestaltet wie die zuvor beschriebene.In a modified embodiment of the device described above, the housing 11 with the cleaning brush 9 cannot be moved back and forth but is arranged in a fixed manner in order to use such a machine, for example, for cleaning reflectors arranged on a street marking line. The structure of this device shown in FIGS. 4 to 6 is the same as that described above.
