Description

Die Erfindung betrifft eine Vorrichtung zur Boden- und Asphaltverdichtung mit mindestens einer Rolle, die eine sich von einer seitlich außenliegenden Stirnebene aus konusartig verjüngende Kontur hat.The invention relates to a device for soil and Asphalt compaction with at least one roller, the one from a laterally outer end plane has a tapered contour.

Beim Verdichten von Boden ist es beispielsweise aus der DE-29 27 883 C2 bekannt, für die Bearbeitung eines Straßenrandes eine Rolle vorzusehen, die eine kegelstumpfartige Kontur hat. Mit dieser Rolle wird die Kante des Straßenbelages mit einer gewissen Abschrägung angedrückt. Diese Abschrägung ist beispielsweise gewünscht bei einem Übergang des Straßenbelages in einen Rinnstein etc.For example, when compacting soil, it is from the DE-29 27 883 C2 known for the processing of a Roadside to provide a role that is a truncated cone Has contour. With this roll, the edge of the road surface with a certain slope pressed. This bevel is desirable, for example when the road surface changes into one Gutter etc.

Falls kein separater Rinnstein vorgesehen ist, kann auch ohne eine derartige Andrückrolle mit der normalen Verdichtungswalze einer Straßenwalze bis dicht an eine seitliche Begrenzung des Straßenbelages, zum Beispiel in Form eines Bordsteines verdichtet werden. Ein derartiger Bordstein hat aber eine abgeschrägte Seitenfläche, so daß mit einer Straßenwalze dicht an ihm vorbeigefahren werden kann, ohne daß die Gefahr besteht, daß die Stirnfläche der Straßenwalze an den Bordstein schrammt. If there is no separate gutter, you can even without such a pressure roller with the normal one Compaction roller of a road roller close to one lateral limitation of the road surface, for example be compacted in the form of a curb. Such one But the curb has a bevelled side, so that a road roller passed close to him can become without the risk that the end face of the road roller to the curb scars.

Bei anderen Anwendungsfällen, zum Beispiel in Höfen, Durchfahrten etc. wird ein entsprechender Belag aber direkt bis an aufsteigendes Mauerwerk heran verlegt. Um diesen Belag zu verdichten, wird dann mit speziell ausgebildeten Verdichtungsmaschinen gearbeitet, bei denen eine Walze seitlich über den eigentlichen Maschinenkörper hinausragt und so dicht entlang der Mauer gefahren werden kann. Problematisch ist dabei aber, daß bereits leichte Fahrfehler mit diesen Maschinen dazu führen können, daß die seitlich herausragende Stirnkante der Walze an der Mauer Schrammen verursacht, was teure Reparaturen sowohl an der Wand als auch an der Maschine verursachen kann.In other applications, for example in courtyards, Passages etc. become a corresponding covering laid directly up to the ascending masonry. Around to compress this covering is then done with specially trained Compaction machines worked on those a roller laterally over the actual machine body protrudes and drove so close along the wall can be. It is problematic, however, that already minor driving errors with these machines can that the laterally protruding front edge of the Roller on the wall scarred, causing expensive repairs both on the wall and on the machine can cause.

Aufgabe der vorliegenden Erfindung ist es daher, eine entsprechende Vorrichtung zur Bodenverdichtung anzugeben, mit der eine größere Sicherheit gegeben ist gegen das Beschädigen einer direkt neben einer zu verdichtenden Bodenschicht aufsteigenden Wand.The object of the present invention is therefore a specify appropriate soil compaction equipment, with which there is greater certainty against damaging one right next to one to be compressed Soil layer ascending wall.

Diese Aufgabe wird erfindungsgemäß mit einer Vorrichtung mit den Merkmalen des Anspruches 1 dadurch gelöst, daß eine Rolle mit sich konusartig verjüngender Kontur verwandt wird, deren Stirnebene nach oben eine Neigung nach innen aufweist, das heißt von der Wand, an der die Rolle entlang geführt wird, oben weggekippt ist. Damit wird erreicht, daß nur im untersten Bereich der Rolle eine Kontaktstelle zwischen der Stirnebene der Rolle und der Wand auftreten kann. Der restliche Bereich der Stirnebene hat einen größeren Abstand zur seitlich neben ihr liegenden Wand und kann somit keine Beschädigungen mehr verursachen. This object is achieved with a device with the features of claim 1 in that a role related to a tapered contour is, whose frontal plane is inclined upwards facing inwards, i.e. from the wall on which the Roll is guided along, is tilted away at the top. In order to is achieved only in the lowest area of the role a contact point between the end plane of the roll and the wall can appear. The rest of the area The end plane has a greater distance to the side next to it your lying wall and can therefore no damage cause more.

Vorteilhafterweise ist dabei die Unterseite der Rolle im wesentlichen horizontal ausgerichtet, wodurch zu erreichen ist, daß zwischen verdichtetem Belag und seitlichem Mauerwerk ein exakter rechter Winkel erzielt wird.Advantageously, the bottom of the roll aligned essentially horizontally, thereby achieving is that between the compacted surface and the side Masonry achieved an exact right angle becomes.

Bezüglich der Befestigung der Rolle kann einerseits eine Lagerung vorgesehen sein, deren Achse um den Neigungswinkel der Stirnebene nach oben geschwenkt ist. Damit ist eine ausgesprochen exakte Kantenführung möglich.Regarding the attachment of the role on the one hand a bearing may be provided, the axis of which about the angle of inclination the end plane is pivoted upwards. This enables extremely precise edge guidance.

Es liegt aber auch im Rahmen der Erfindung, die Rolle über elastische Elemente an einer Lagerung zu befestigen, die eine horizontale Achse aufweist. Mit dieser Variante lassen sich auch bereits vorhandene Verdichtungsvorrichtungen auf die erfindungsgemäße Rolle umrüsten. Dabei können die elastischen Elemente dann sich in Axialrichtung verformende Gummipuffer sein, die rollenseitig an einem parallel zur Stirnebene verlaufenden Befestigungsflansch angreifen. Diese elastischen Elemente können den dabei zwischen Rolle und Achse auftretende Versatz in der Größenordnung von etwa 5°, vorzugsweise 1° bis 2° problemlos ausgleichen.But it is also within the scope of the invention, the role to be attached to a bearing via elastic elements, which has a horizontal axis. With this Already existing compression devices can also be used as a variant convert to the role according to the invention. The elastic elements can then be rubber buffers deforming in the axial direction, the roller side on a parallel to the forehead plane Attack the mounting flange. These elastic elements can be the one that occurs between the roller and the axle Offset of the order of about 5 °, preferably compensate for 1 ° to 2 ° without any problems.

Grundsätzlich kann eine derartige Rolle als Zusatzteil für eine Straßenwalze vorgesehen werden und als solches an einem separaten Kragarm befestigt werden.In principle, such a role can be used as an additional part be provided for a road roller and as such attached to a separate cantilever.

Es ist aber nur im Rahmen der hier vorliegenden Erfindung, die Verdichtungswalze einer Straßenwalze entsprechend auszubilden. But it is only within the scope of the present invention, the compaction roller to train according to a road roller.

Dabei hat es sich als besonders günstig herstellbar erwiesen, die Walze mittels einer Bandage herzustellen, die einen keilförmigen Querschnitt aufweist, was mit einer im wesentlichen zylindrischen Innenkontur der Walze einhergeht. Bei einer anderen Ausführungsform entspricht der Zuschnitt der Bandage insgesamt der Abwicklung eines Kegelstumpfmantels und ist somit über den gesamten Querschnitt gleich dick.It has proven to be particularly inexpensive to manufacture to manufacture the roller by means of a bandage, which has a wedge-shaped cross-section, what with a substantially cylindrical inner contour of the Roller goes along. In another embodiment the cut of the bandage corresponds to the overall processing of a truncated cone and is therefore over the entire cross-section of equal thickness.

Die erfindungsgemäßen Walzen lassen sich sowohl bei rein statischem Einsatz der Straßenwalze verwenden, als auch mit Vibrationen.The rollers according to the invention can be both use only static use of the road roller as even with vibrations.

Bei Straßenwalzen kann dabei eine über die gesamte Arbeitsbreite gehende Verdichtungswalze mit der sich konusartig verjüngenden Kontur vorgesehen sein. Dabei ist es auch möglich, bei einer Tandemwalze sowohl die vordere als auch die hintere Walze erfindungsgemäß auszubilden, wobei die Vorder- und Hinterwalze in entgegengesetzten Richtungen seitlich über den eigentlichen Maschinenkörper der Straßenwalze hinausragen. Die Achsen der Verdichtungswalzen sind dabei in entgegengesetzte Richtungen geneigt, so daß jeweils die außen liegenden Stirnebenen sowohl der Vorder- als auch der Hinterwalze in der Richtung nach oben nach innen geneigt sind.With road rollers, one can cover the entire working width going compacting roller with the cone-like tapered contour may be provided. It is it is also possible to use both the front one with a tandem roller as well as to design the rear roller according to the invention, the front and rear rollers in opposite Directions laterally over the actual one The machine body protrudes from the road roller. The axes the compaction rollers are in opposite Directions inclined so that each the outside lying frontal planes of both the front and the Rear roller inclined inward in the upward direction are.

Alternativ hierzu wird vorgeschlagen, an einer Achse der Straßenwalze, vorzugsweise vorne, zwei entgegengesetzt gerichtete erfindungsgemäße Rollen als Verdichtungswalzen zu montieren, bei denen die jeweils außen liegenden Stirnseiten ebenfalls seitlich über den Maschinenkörper hinausragen und in der Richtung nach oben nach innen geneigt sind. Da bei einer derartigen Ausbildung einer Straßenwalze wegen der dann innenliegenden Halterung für die beiden Walzen bei der Verdichtung ein mittlerer Bereich unbearbeitet bleibt, wird eine derartige Straßenwalze auch eine diesen mittleren Bereich bearbeitende Verdichtungswalze aufweisen. Diese weitere Verdichtungswalze ist dabei vorzugsweise eine an der anderen Achse montierte Verdichtungswalze herkömmlicher Bauweise, das heißt mit zylindrischer Außenkontur und einer Breite, die geringer ist als die der beiden Walzen an der erstgenannten anderen Achse.Alternatively, it is proposed to use an axis the road roller, preferably in front, two opposite directional rollers according to the invention as compaction rollers to mount, each with the outside lying end faces also laterally over the Protrude machine body and in the direction are inclined inwards at the top. Because with such Formation of a road roller because of the inside Bracket for the two rollers during compaction a middle area remains unprocessed such a road roller also a medium one Have area processing compaction roller. This another compacting roller is preferably a compacting roller mounted on the other axis is more conventional Construction, that is, with a cylindrical outer contour and a width that is less than that two rollers on the first other axis.

In Figur 1 wird eine Andrückrolle gezeigt, die als Anbauteil an einer bekannte Straßenwalze ausgebildet ist. Diese Straßenwalze hat eine Verdichtungswalze mit einer zylindrischen Bandage 1, mit der in bekannter Weise die Verdichtung eines Bodens oder Bodenbelages 2 erfolgt. Im dargestellten Beispiel wird der Bodenbelag bis an eine senkrecht aufsteigende Mauer 3 verlegt und soll bis zu der entsprechenden Anschlußstelle verdichtet werden. Üblicherweise wird dazu mit der Straßenwalze dicht entlang der Mauer 3 gefahren, wobei die Stirnkante 4 der Verdichtungswalze direkt parallel an der Mauer 3 entlang geführt wird. Leichte Fahrfehler führen dabei schon zu einer Beschädigung der Mauer 3 und damit zu teuren Reparaturen.A pressure roller is shown in FIG. the as an attachment to a known road roller is trained. This road roller has a compaction roller with a cylindrical bandage 1, with the in a known manner the compaction of a soil or Flooring 2 is done. In the example shown, the flooring up to a vertical wall 3 relocated and should go to the appropriate junction be compressed. Usually this is done with the road roller drove closely along the wall 3, the end edge 4 of the compacting roller directly is guided in parallel along the wall 3. light Driving errors already damage the Wall 3 and therefore expensive repairs.

Um dies zu verhindern, wird neben der zylindrischen Bandage eine Rolle 5 auf den Boden 2 gedrückt, die im. wesentlichen die Form eines Kegelstumpfes hat, das heißt eine Kontur, die sich von einer seitlich außenliegenden Stirnebene 6 konusartig verjüngt. Diese Rolle ist jetzt so geneigt, daß die Stirnebene 6 nach oben eine Neigung nach innen aufweist. - Soweit hier von außen oder innen gesprochen wird bezieht sich dies auf die Längsachse der Straßenwalze. -To prevent this, next to the cylindrical Bandage pressed a roller 5 on the floor 2, which in. essentially has the shape of a truncated cone that is the name of a contour that extends from the side on the outside Frontal plane 6 tapers conically. This role is now inclined so that the end plane 6 upwards has an inward slope. - So far from here speaking outside or inside refers to the longitudinal axis of the road roller. -

So wird erreicht, daß die Rolle 5 nur im unteren Bereich 7 Kontakt mit der Wand 3 haben kann, während sie ansonsten einen ausreichenden Abstand zu dieser einhält. Damit führen leichte Fahrfehler nicht zu einer Beschädigung des Gebäudes.This ensures that the Roller 5 only in the lower area 7 contact with the wall 3 can have, while otherwise a sufficient Maintains a distance from this. This leads to slight driving errors not damage the building.

Die Unterseite 8 der Rolle ist dabei horizontal ausgerichtet, so daß der gesamte Boden 2 eine einheitlich ebene Fläche bildet.The bottom 8 of the roll is aligned horizontally, so that the entire floor 2 one forms a flat surface.

Die Rolle 5 ist über eine starre Lagerung 9 an einem Kragarm 10 befestigt, mit dem sie in bekannter Weise in eine Betriebsposition und aus dieser herauszuschwenken ist. The roller 5 is on a rigid bearing 9 Cantilever arm 10 attached, with which they in a known manner an operating position and swing out of this is.

Die starre Lagerung 9 ist dabei so ausgebildet, daß ihre Achse 23 um einen Winkel nach oben geschwenkt ist, der dem Neigungswinkel 11 der Stirnebene 6 der Rolle entspricht. Aufgrund dieser starren Lagerung ist die Rolle exakt zu führen.The rigid bearing 9 is designed so that its axis 23 is pivoted upwards by an angle, the angle of inclination 11 of the end plane 6 of the roller equivalent. Because of this rigid storage, the To guide the roll exactly.

In der Figur 2 ist eine Ausführungsform der Erfindung dargestellt. Gleiche Gegenstände sind mit gleichen Bezugsziffern versehen.FIG. 2 shows an embodiment of the Invention shown. Same items are with provided with the same reference numbers.

Bei der in Figur 2 dargestellten Ausführungsform der Erfindung ist die Rolle als Verdichtungswalze 12 einer Straßenwalze ausgebildet. Von der Straßenwalze ist lediglich das Antriebsgehäuse 13 sowie ein Teil des dieses tragende Chassis gezeigt. Die Verdichtungswalze 12 hat ebenfalls eine Kontur, die sich von einer seitlich außenliegenden Stirnebene 14 aus konusartig verjüngt. Indem die Verdichtungswalze mit ihrem sich konusartig verjüngenden Mantel auf dem Boden 2 aufsteht, wird die genannte Stirnebene 14 leicht nach innen geneigt, wodurch auch mit einer derart ausgebildeten Verdichtungswalze 12 an einer Mauer 3 entlang gefahren werden kann, wobei nur in einem unteren Bereich 7 ein Kontakt zwischen der Verdichtungswalze 12 und der Mauer 3 auftreten kann.In the embodiment shown in Figure 2 Invention is the role of a compaction roller 12 Road roller trained. From the road roller is only the drive housing 13 and part of this supporting chassis shown. The compacting roller 12 also has a contour that extends from a side outer end plane 14 tapers from cone-like. By making the compacting roller cone-like tapered coat stands on the floor 2, the called end plane 14 slightly inclined inwards, whereby also with such a compacting roller 12 can be driven along a wall 3, only in a lower area 7 a contact between the compacting roller 12 and the wall 3 occur can.

Die sich konusartig verjüngende Kontur der Verdichtungswalze wird erreicht, indem die Bandage 16 der Walze im Querschnitt keilförmig ausgebildet ist. Im inneren hat die Verdichtungswalze 12 so eine zylinderförmige Ausgestaltung. The tapered contour of the compaction roller is achieved by the bandage 16 of the Roll is wedge-shaped in cross section. in the Inside, the compacting roller 12 has a cylindrical shape Design.

Zur Befestigung der Verdichtungswalze weist sie einen Befestigungsflansch 17 auf, der parallel zur Stirnebene 14 verläuft und über den sie an einen Antrieb oder ihre sonstige Lagerung an der Straßenwalze anzukoppeln ist. Dabei befinden sich zwischen diesem Befestigungsflansch 17 und der entsprechenden straßenwalzenseitigen Ankoppelscheibe 18 über den Umfang des Flansches verteilt eine Mehrzahl von elastischen Elementen 19, mit denen ein Winkelausgleich erfolgen kann zwischen der geneigten Mittelachse 20 der Verdichtungswalze 12 und der horizontal verlaufenden Achse 21 des Antriebes. Dieser Winkelunterschied beträgt etwa 1° bis 5°, vorzugsweise 1° bis 2°. Aufgrund dieser elastischen Ankoppelung ist es möglich, eine derart erfindungsgemäß ausgebildete Verdichtungswalze auch bei den bisher verwandten Straßenwalzen anzubringen. Selbstverständlich liegt es auch im Rahmen der Erfindung, die antriebsseitige Achse gemäß der geneigten Mittelachse der Verdichtungswalze auszurichten und die Verdichtungswalze dann starr zu befestigen.It has one for attaching the compacting roller Mounting flange 17, which is parallel to the end plane 14 runs and via which they are connected to a drive or their other storage must be coupled to the road roller. There are between this mounting flange 17 and the corresponding coupling roller on the road roller side 18 distributed over the circumference of the flange a plurality of elastic elements 19 with which an angle compensation can take place between the inclined Central axis 20 of the compacting roller 12 and horizontal axis 21 of the drive. This Angular difference is about 1 ° to 5 °, preferably 1 ° to 2 °. Because of this elastic coupling it is possible to design such a device according to the invention Compaction roller also in the previously used road rollers to install. Of course it is too in the context of the invention, the drive-side axis according to the inclined central axis of the compacting roller align and then the compacting roller rigidly Fasten.

Grundsätzlich kann dabei die Verdichtungswalze gemäß den bisher bekannten Methoden sowohl statisch eingesetzt werden oder aber mit Vibrationen.Basically, the compaction roller can the previously known methods are used both statically or with vibrations.

Während die in Figur 2 dargestellte Verdichtungswalze sich über die gesamte Breite einer Straßenwalze erstrecken kann, ist in Figur 3 eine Variante dargestellt, bei der zwei sich von außen zur Mitte hin konusartig verjüngende erfindungsgemäße Verdichtungswalzen zu erkennen sind. Diese sind wie in der Figur 2 dargestellt jeweils über elastische Elemente 19 an entsprechenden Ankoppelscheiben 18 befestigt, über die sie vom Antrieb 13 kommend angetrieben werden. Da die entsprechenden Mittelachsen 20 für beide Walzen nach oben geneigt sind, wird der Boden 2 insgesamt eben verdichtet. Dabei bleibt aber ein zwischen den beiden Verdichtungswalzen liegender Bereich 22 unbearbeitet. Er wird von einer weiteren, hier nicht dargestellten Verdichtungswalze der Straßenwalze nachverdichtet. Da die Stirnebenen 14 der beiden Verdichtungswalzen 12 jeweils nach innen geneigt sind, eignet sich eine derartige Walzenkombination, um alternativ oder aber gleichzeitig einen Boden bis an eine links oder rechts aufragende Wand 3 heran zu verdichten, ohne daß die Gefahr besteht, mit leichten Lenkfehlern an dieser Wand Schäden zu verursachen.While the compaction roller shown in Figure 2 extend across the entire width of a road roller a variant is shown in FIG. 3, where the two cone-like from the outside to the center tapering compaction rollers according to the invention are recognizable. These are as in FIG. 2 shown in each case via elastic elements 19 corresponding coupling discs 18 attached via the they are driven by the drive 13 coming. Since the corresponding central axes 20 for both rollers are inclined at the top, the bottom 2 becomes flat overall compacted. But there remains one between the two Compaction rollers lying area 22 unprocessed. He is from another, not shown here Compaction roller of the road roller post-compressed. There the end planes 14 of the two compaction rollers 12 are inclined inwards, one is suitable such roller combination, alternatively or at the same time a floor up to a left or right towering wall 3 to compress without the risk exists, with slight steering errors on this wall Cause damage.
