Die bekannten Strassenfertiger, die Strassendecken in einem Arbeitsgang herstellen, bestehen im wesentlichen aus einem, auf einer planierten Unterlage fahrenden Fahrzeug und einem, das Material für die Strassendecke verarbeitenden Gerät, das als Vibrations- oder Stampferbohle ausgebildet ist. Die Erfindung betrifft ein als Vibrationsbohle ausgebilde¬ tes Gerät, welches - in Arbeitsrichtung gesehen - hinter dem Fahrzeug angeordnet ist. Das auf der Vorderseite des Fahrzeugs eingeführte Deckenmaterial wird durch eine Förder-The known road pavers, which produce road surfaces in one work step, consist essentially of a vehicle traveling on a leveled surface and a device which processes the material for the road surface and which is designed as a vibrating or ramming screed. The invention relates to a device designed as a vibration screed, which - seen in the working direction - is arranged behind the vehicle. The ceiling material introduced on the front of the vehicle is conveyed by a conveyor
OMPI - 4~ WiP0 einrichtung in den zwischen dem Fahrzeug und der Vibra¬ tionsbohle liegenden Raum gebracht und dort durch eine Förderschnecke gleichmässig auf die Arbeitsbreite der Vibrationsbohle ausgebreitet. Die Vibrationsbohle hat die Aufgabe, das noch lose ankommende Deckenmaterial auf die gewünschte Deckenhöhe zu verdichten.OMPI - 4 ~ WiP0 device brought into the space between the vehicle and the vibrating screed and spread there evenly over the working width of the vibrating screed by a screw conveyor. The vibrating screed has the task of compacting the ceiling material that is still arriving loosely to the desired ceiling height.
Der Aufbau der Vibrationsbohle ist bei den bekannten Aus¬ führungen ähnlich. Ein aus meistens zwei Teilen bestehender Basisteil weist eine Verdichtungsplatte auf, die durch einen Schwingantrieb, in Schwingungen versetzt wird, wo- . durch das Depkenrnäterial .auf die gewünschte Höhe ver¬ dichtet wird.

A base part, which usually consists of two parts, has a compression plate which is made to vibrate by an oscillating drive. is compressed to the desired height by the depository material. The base part carries a scraper, which ensures the correct material dosage. The compression is facilitated by the supply of hot fuel gases which are generated by means of gas burners.
Obwohl verschiedene bekannte Strassenfertiger seit längerer Zeit' im Strassenbau verwendet werden, ist nicht zu über¬ sehen, dass von selten des Benutzers der Strassenfertiger eine Weiterentwicklung bezüglich einer besser einstellbaren - Verdichtung gewünscht wird.Although various known pavers are used for a long time 'in road construction, is not seen to über¬ that of rare user of asphalt pavers a better adjustable with respect to an advancement - compression is desired.
Hier setzt die Erfindung ein, deren Aufgabe es ist, einen Strassenfertiger mit einer Vibrationsbohle so auszugestal¬ ten, dass bei einfacher Bedienung eine verbesserte Einstell¬ barkeit der Verdichtung des Deckenmaterials erreicht und • die vorgeschriebene Deckenhöhe exakt eingehalten werden kann.This is where the invention comes in, the task of which is to design a paver with a vibrating screed in such a way that, with simple operation, an improved adjustability of the compression of the ceiling material is achieved and • the prescribed ceiling height can be exactly maintained.
Diese Aufgabe wird gemäss der Erfindung durch die kenn¬ zeichnenden Merkmale der Ansprüche 1, 3 und 6 gelöst.This object is achieved according to the invention by the characterizing features of claims 1, 3 and 6.

In den Figuren 1 - 3 ist eine Vibrationsbohle nur teil¬ weise, d.h. im wesentlichen nur die eine Hälfte, darge¬ stellt, da die Hälften gegengleich ausgeführt sind. Die Vibrationsbohle 1 ist an zwei Armen 2 befestigt {Fig. 1) . Die Befestigung ist durch eine strichpunktierte Verbindungs¬ linie, angedeutet. Die Arme 2 verlaufen beidseits der Längs-' seiten eines Fahrzeugs 4 und sind höheneinstellbar und schwenkbar an demselben abgestützt. Durch die Höheneinstel¬ lung der Arme 2 wird die Vibrationsbohle 1 in ihrer Lage geführt.In FIGS. 1-3, a vibrating screed is only partially, ie essentially only half, shown, since the halves are constructed in opposite directions. The vibrating screed 1 is attached to two arms 2 {Fig. 1) . The attachment is indicated by a dash-dotted connecting line. The arms 2 run on both sides of the longitudinal ' sides of a vehicle 4 and are height-adjustable and pivotally supported on the same. The vibrating screed 1 is guided in its position by the height adjustment of the arms 2.
Die Vibrationsbohle 1 setzt sich aus einem- Basisteil 3, der seinerseits aus zwei gleichen Teilen 6, 7 besteht, einem am Basisteil 3 abgestützten Vorabstreifer 8 und einem Vibrationsteil 9 zusammen. Der Vibrationsteil 9 weist einen Schwihgantrieb 10 auf, der sich aus einer Antriebswelle 11, einem Exzenter 12 und einem Lenker 13 zu¬ sammensetzt, welch letzterer an einer Verdichtungsplatte 15 angelenkt ist*. Die Welle 11 ist in Stehlager 14 gelagert und über einen Riementrieb 21, von einem Antriebsmotor, z.B. einem nicht dargestellten Hydromotor, angetrieben.The vibrating screed 1 is composed of a base part 3, which in turn consists of two identical parts 6, 7, a preliminary scraper 8 supported on the base part 3 and a vibration part 9 together. The vibrating part 9 has a floating drive 10, which is composed of a drive shaft 11, an eccentric 12 and a link 13, the latter being articulated on a compression plate 15 * . The shaft 11 is mounted in the pedestal bearing 14 and is driven by a drive motor, for example a hydraulic motor, not shown, via a belt drive 21.
Entsprechend der in Fig. 1 angedeuteten Arbeitsrichtung 5 erfolgt die Materialzufuhr zur Vibrationsbohle 1 vom Fahrzeug 4 her. Der materialzufuhrseitige Rand 16 der Ver¬ dichtungsplatte 15 ist aufwärts gewölbt und bildet zusammen mit einer Bodenunterlage 22 einen sich verengenden Spalt, in welchem das zugeführte Material durch die von der Ver¬ dichtungsplatte 15 ausgeführten Schwingungen verdichtet wird. Die Verdichtungsplatte 15 ist an dem, dem material- zufuhrseitigen Rand 16 gegenüberliegenden Rand 17 am Basis¬ teil 3 befestigt. Da die Verdichtungsplatte 15 Vibrationen ausführt, ist unmittelbar am Rand 17 ein Bandgelenk 18 ange¬ ordnet, das ein integraler Bestandteil der Verdichtungsplatt 15 ist und sich gegenüber den übrigen Teilen der Verdich¬ tungsplatte 15 durch eine geringere Materialstärke auszeich¬ net.According to the working direction 5 indicated in FIG. 1, the material supply to the vibrating screed 1 takes place from the vehicle 4. The edge 16 of the compression plate 15 on the material feed side is curved upward and, together with a base support 22, forms a narrowing gap in which the material supplied is compressed by the vibrations carried out by the compression plate 15. The compression plate 15 is fastened to the base part 3 at the edge 17 opposite the material feed side edge 16. Since the compression plate 15 vibrates, a hinge 18 is arranged directly at the edge 17, which is an integral part of the compression plate 15 and is distinguished from the other parts of the compression plate 15 by a lower material thickness.
Wie bereits erwähnt wurde und aus Fig. 2 und 3 ersichtlich ist, besteht der Basisteil aus zwei Teilen 6, 7. Dementspre¬ chend ist auch die Verdichtungsplatte 15 in zwei Teile unterteilt, welche in der Nähe der Verdichtungsplatte 15 durch ein Gelenk 19 miteinander verbunden sind.- Durch das Gelenk 19 sind somit auch die beiden Teile 6, 7 des Basis¬ teils 3 miteinander verbunden, können jedoch durch ein von einem Schubkolbenantrieb 23 betätigten Gestänge 24 gegen- einander verschwenkt werden. Es kann damit eine leicht dachförmige Fahrbahndecke - positive Bombierung der Basis¬ platte 3 - oder eine rinnenförmige Fahrbahndecke - negative Bombierung der Basisplatte 3 - erreicht-werden.As has already been mentioned and can be seen from FIGS. 2 and 3, the base part consists of two parts 6, 7. Accordingly, the compression plate 15 is also divided into two parts which are connected to one another in the vicinity of the compression plate 15 by a joint 19 The two parts 6, 7 of the base part 3 are thus also connected to one another by the joint 19, but can be counteracted by a linkage 24 actuated by a thrust piston drive 23. be pivoted to each other. A slightly roof-shaped road surface - positive crowning of the base plate 3 - or a channel-shaped road surface - negative crowning of the base plate 3 - can thus be achieved.
Das in Fig. 5 und 6 vergrössert dargestellte Gelenk 19 weist eine Gelenkachse 20 auf, die mit de Unterseite der Verdichtungsplatte 15 fluchtet. Die Enden 32 der Verdich- • tungsplatten 25 sind etwas geneigt, so dass eine geringe negative Bombierung einstellbar ist. Auf der Oberseite der Enden 32 ist ein Walzensegment 31 gelagert, dessen Zentriwinkel etwas kleiner als 180 ist. Das Walzensegment 31 ist in Scharnierlaschen 30 geführt, die wechselweise auf dem einen und dem anderen Ende 32 der Verdichtungsplatten 25 durch Schrauben 33 befestigt sind. Die Scharnierlaschen 30 und das Walzensegment 31 bilden, zusammen ein Walzenge¬ lenk.The joint 19, shown enlarged in FIGS. 5 and 6, has a joint axis 20 which is aligned with the underside of the compression plate 15. The ends 32 of the compression plates 25 are slightly inclined so that a slight negative crowning can be set. A roller segment 31 is mounted on the upper side of the ends 32, the central angle of which is somewhat less than 180. The roller segment 31 is guided in hinge tabs 30 which are alternately fastened on one and the other end 32 of the compression plates 25 by screws 33. The hinge tabs 30 and the roller segment 31, together form a roller joint.
Aus Fig. 1 und 3 ist ersichtlich, dass vor den Teilen 6, 7 des Basisteils 3 je ein Ausschubteil 36 gelagert sein kann. Der Ausschubteil 36 ist. gleich ausgebildet wie der Basisteil 3 und weist einen Vibrationsteil mit einem Schwingantrieb 10 und einer Verdichtungsplatte 15 auf. An den Ausschubteilen 36 ist ein Laufsteg 37 gelagert.It can be seen from FIGS. 1 and 3 that an extension part 36 can be mounted in front of the parts 6, 7 of the base part 3. The extension part 36 is. the same design as the base part 3 and has a vibration part with a vibratory drive 10 and a compression plate 15. A catwalk 37 is mounted on the extension parts 36.
Das Ein- und Ausziehen des Ausschubteils erfolgt mittels hydraulischer Schubkolbenantriebe 23, die zwischen zwei mit dem Ausschubteil 36 verbundenen Führungsrohren 28 ange¬ ordnet sind. Die Führungsrohre 28 sind ihrerseits in einer Führungshülse 29 geführt.The extension part is pulled in and out by means of hydraulic thrust piston drives 23 which are arranged between two guide tubes 28 connected to the extension part 36. The guide tubes 28 are in turn guided in a guide sleeve 29.
Die Teile 6, 7 des Basisteils 3 und der Ausschubteil 36 sind durch Querwände 34 (Fig. 2 und 3) versteift, in denen einerseits Durchgänge für die Schwingantriebe 10 vorge- sehen sind und andererseits die Stehlager 14 der Schwing¬ antriebe 10, die Schubkolbenantriebe 23, 27 und die Füh¬ rungshülsen 29 befestigt sind. Weitere Durchgänge dienen dazu, Kanäle für die Zuführung von Brenngasen zur Ver¬ dichtungsplatte 15 aufzunehmen, deren Zuleitungen 35 in Fig. 3 angedeutet sind.The parts 6, 7 of the base part 3 and the extension part 36 are stiffened by transverse walls 34 (FIGS. 2 and 3), in which, on the one hand, passages for the oscillating drives 10 are provided. can be seen and on the other hand the pillow block bearings 14 of the oscillating drives 10, the thrust piston drives 23, 27 and the guide sleeves 29 are fastened. Further passages serve to receive channels for the supply of fuel gases to the compression plate 15, the feed lines 35 of which are indicated in FIG. 3.
Wie bereits erwähnt wurde., ist der Vorabstreifer 8 am Basisteil 3 abgestützt. Entsprechend seiner Unterteilung in die Teile 6, 7 weist auch der Vorabstreifer 8 zwei Teile auf (Fig. 3) . Der Ausschubteil 36 ist zudem mit einem aus- schiebbaren Vprabstreiferteil 37' verbunden. Da der Vorschubteil 36 die Arbeitsbreite bestimmt, sind die Teile 36, 37' durch eine Seitenführung 38' begrenzt die gleichzeitig die Verbindung zwischen den beiden Teilen darstellt.As has already been mentioned, the preliminary scraper 8 is supported on the base part 3. According to its subdivision into parts 6, 7, the preliminary scraper 8 also has two parts (FIG. 3). The extension part 36 is also connected to an extendable pre-wiper part 37 '. Since the feed part 36 determines the working width, the parts 36, 37 'are delimited by a side guide 38' which simultaneously represents the connection between the two parts.
Der Vorabstreifer 8 hat die Aufgabe, die Dosierung des noch nicht verdichteten Deckenmateri'als zu gewährleisten und ist deshalb gegenüber dem Basisteil -3 verstellbar. Die Erfindung sieht nun vor, den Vorabstreifer 8 entsprechend der vorgesehenen Höhe der fertigen Strassendecke selbst¬ tätig so einzustellen, dass bei jeder Deckenhöhe die richtige Materialdosierung erfolgt. Dies wird durch eine Vorabstreifersteuerung 55 gemäss Fig. 4 erreicht. Auf dem Scheitelsteg 38 des Basisteils 3 ist ein Support 40 mit einer Lagerhülse 39 befestigt. In der Lagerhülse 39 ist eine Welle 41 schwenkbar gelagert. An dem einen Ende der Welle 41 ist ein den Vorabstreifer 8 tragender Hebel 44 be¬ festigt. Die Verbindung zwischen dem Hebel 44 und dem Vor¬ abstreifer 8 erfolgt über eine Lasche 42 und einen im Vor¬ abstreifer 8 befestigten Ringbolzen 43. Am anderen Ende der Welle 41 ist ein Arm 45 befestigt, dessen freies Ende mit¬ tels eines Zapfens 46 in einer der Bohrungen-47 eines Sup¬ ports 48 schwenkbar gelagert ist. Der Support 48 ist amThe pre-stripper 8 has the task of the dosage of the not yet compacted Deckenmateri 'as to guarantee and therefore is adjustable relative to the base part 3. The invention now provides for the preliminary scraper 8 to be set automatically in accordance with the intended height of the finished road surface in such a way that the correct material is metered at every height of the ceiling. This is achieved by a scraper control 55 according to FIG. 4. A support 40 with a bearing sleeve 39 is fastened on the crown web 38 of the base part 3. A shaft 41 is pivotally mounted in the bearing sleeve 39. At one end of the shaft 41, a lever 44 carrying the scraper 8 is fastened. The connection between the lever 44 and the pre-scraper 8 takes place via a tab 42 and an annular bolt 43 fastened in the pre-scraper 8. An arm 45 is fastened to the other end of the shaft 41, the free end of which is by means of a pin 46 in one of the bores 47 of a support 48 is pivotally mounted. Support 48 is on

If a specific ceiling height, for example A or B, is now prescribed, the corresponding settings a or b of the scraper 8 are set by the lever 44, which represent the correct dosage for the relevant height. If a fine adjustment is desired, this can be achieved by means of a spindle which is mounted on the arm 45 and acts on a lever attached to the sleeve 39.
Mit der beschriebenen Vibrationsbohle 1 kann die vorge¬ schriebene Deckenhöhe genau eingehalten werden, da die Verdichtungsplatte 15 an ihrem Rand 17 mit dem Basisteil 3 fest verbunden ist. Der Vibrationshub wird durch den formschlüssigen Exzenterantrieb in jedem Falle gewähr¬ leistet, wobei das Bandgelenk 18 eine einfache Lösung 'zur Vermeidung von Ueberbea-nspruchungen an der Biegestelle darstellt. -With the vibrating screed 1 described, the prescribed ceiling height can be maintained exactly, since the compression plate 15 is firmly connected at its edge 17 to the base part 3. The vibration stroke is guaranteed by the positive eccentric drive in each case, the hinge 18 being a simple solution for avoiding excessive stresses at the bending point. -
Durch das Walzengelenk 19 wird erreicht, dass die Gelenk- achse genau mit der Unterseite 25 der Verdichtungsplatte 15 fluchtet, so dass dadurch die Einstellung der Bombie¬ rung erleichtert wird. Eine weitere Vereinfachung tritt dadurch ein, dass die Einstellung des Vorabstreifers 8 selbsttätig entsprechend der am Basisteil 3 eingestellten Deckenhöhe erfolgt. The roller joint 19 ensures that the joint axis is exactly aligned with the underside 25 of the compression plate 15, so that the setting of the bombing is thereby facilitated. A further simplification occurs in that the setting of the preliminary scraper 8 takes place automatically in accordance with the ceiling height set on the base part 3.
