Description

Die Erfindung betrifft ein kombiniertes Fugenschneid-Straßenfräs-Anbaugerät für Hydraulikbagger, Baggerlader und Frontlader.The invention relates to a combined joint cutting road milling attachment for hydraulic excavators, backhoe loaders and front loaders.

Es gibt selbstfahrende Straßenfräsen und Anbau-Straßenfräsen für Traktoren, und es gibt selbstfahrende Fugenschneider mit Diamantscheiben (z. B. nach der DE-A-2 040 890). Es gibt eine Anzahl von Anbaugeräten für Bagger, Baggerlader und Frontlader für verschiedene Einsatzzwecke (z. B. gemäß DE-A-2 741 114), aber nicht für Fräsen und Fugenschneiden. Das Neue an diesem Gerät ist die Kombination von Fugenfräsen und Straßenfräsen in einem Gerät in Verbindung mit der Anbringung dieses Gerätes als Anbaugerät an Hydraulikbagger, bzw. Baggerlader, bzw. Frontlader gemäß Anspruch 1. Mit diesem Gerät kann jeder Hydraulikbagger, Baggerlader und Frontlader jetzt auch als Straßenfräsgerät bzw. als Fugenschneider eingesetzt werden. Dadurch werden diese Geräte universeller und wirtschaftlicher einsetzbar. Auf fast jeder Tief- und Straßenbaustelle befindet sich ein Bagger, Baggerlader oder Frontlader, der sehr oft nicht voll ausgelastet wird. Während dieser Zeit können diese Geräte mit dem kombinierten Anbau-Straßenfräs-Fugenschneidgerät die auf der jeweiligen Baustelle anfallenden Fugenschneid- bzw. Straßenfräsarbeiten ausführen. Die Fräswalze ist innerhalb weniger Minuten auszuwechseln gegen die Frässcheibe und umgekehrt. Durch den Anbau einer Grabenfräseinrichtung, bei der das Antriebsrad für die Grabenfräskette von der Antriebswelle für die Fräswalze bzw. die Frässcheibe angetrieben wird, können. auch zusätzlich mit diesem Gerät Grabenfräsarbeiten ausgeführt werden.There are self-propelled road milling machines and add-on road milling machines for tractors, and there are self-propelled joint cutters with diamond disks (e.g. according to DE-A-2 040 890). There are a number of attachments for excavators, backhoe loaders and front loaders for various purposes (e.g. according to DE-A-2 741 114), but not for milling and joint cutting. The new thing about this device is the combination of joint milling and road milling in one device in connection with the attachment of this device as an attachment to hydraulic excavators, or backhoe loaders, or front loaders according to claim 1. With this device, every hydraulic excavator, backhoe loader and front loader can now can be used as a road milling machine or as a joint cutter. This makes these devices more universal and more economical to use. There is an excavator, backhoe loader or front loader on almost every underground and road construction site, which very often is not fully utilized. During this time, these devices can use the combined add-on road milling joint cutting device to carry out the joint cutting or road milling work at the respective construction site. The milling drum can be replaced with the milling disk and vice versa within a few minutes. By installing a trench milling device, in which the drive wheel for the trench milling chain is driven by the drive shaft for the milling drum or the milling disk. trench milling work can also be carried out with this device.

Kanal- und Rohrleitungsbauer können auf ihren Baustellen mit diesem Gerät zunächst mit der Frässcheibe die Fugen schneiden. Nachdem der Graben ausgehoben, die Rohre verlegt, der Graben wieder verfüllt und das Unterbaumaterial eingebracht worden ist, können sie dann die Ränder mit der Fräswalze auf 10 bis 20 cm Breite 2-3 cm tief abfräsen, damit ein besserer Verbund zwischen der alten und der neuen Decke hergestellt wird. Kabelbauer brauchen auf Fußwegen, wo die meisten Kabel verlegt werden, nicht mehr zweimal schneiden. Viele Fußwege sind nur mit einer dünnen Verschleißschicht von ca. 2 cm versehen. Darunter befindet sich eine Bitumenkiesschicht von ca. 8-10 cm. Das hier beschriebene Gerät kann mit der Fräswalze in einem Arbeitsgang auf einer Breite von 20 cm und einer Tiefe bis zu 12 cm die gesamte Verschleiß- und Bitukiesschicht herausfräsen. Dieses ist mit herkömmlichen Geräten nicht möglich. Kleinfräsen, die auf Fußwegen fahren können, sind zu leicht und haben nicht genügend Kraft. Großfräsen können nicht auf Fußwegen fahren. Bei dem hier beschriebenen Gerät ist eine solche Arbeit möglich, weil der Bagger auf der Straße fahren und gleichzeitig mit ausgeschwenktem Ausleger, an dem das hier beschriebene Gerät angebracht ist, die Fräserarbeit auf dem Fußweg ausführen kann. Anschließend kann mit der Grabenfräse der Graben ausgehoben werden. Hinzu kommt in diesem Fall ein weiterer Rationalisierungseffekt, nämlich der, daß das fein zerkleinerte Deckenmaterial wieder als Unterbau für die neue Verschleißdecke verwendet werden kann.Sewer and pipeline builders can first use this device to cut the joints on their construction sites using the milling disk. After the trench has been excavated, the pipes laid, the trench filled again and the substructure material has been brought in, you can then mill the edges with the milling drum to a depth of 10 to 20 cm to a depth of 2-3 cm so that a better bond between the old and the new blanket is manufactured. Cable builders no longer need to cut twice on footpaths where most cables are laid. Many footpaths are only covered with a thin wear layer of approx. 2 cm. Below this is a layer of bitumen gravel of approx. 8-10 cm. With the milling drum, the device described here can mill out the entire wear and bituminous layer in one operation over a width of 20 cm and a depth of up to 12 cm. This is not possible with conventional devices. Small milling machines that can drive on footpaths are too light and do not have enough power. Large milling machines cannot drive on footpaths. With the device described here, such work is possible because the excavator can drive on the road and at the same time can carry out the milling work on the footpath with the boom pivoted out, to which the device described here is attached. The trench can then be dug out. In addition, there is another rationalization effect in this case, namely that the finely shredded ceiling material can be used again as a substructure for the new wear ceiling.

Der Straßenbauer kann mit seinem Bagger ausgerüstet mit dem hier beschriebenen Gerät jetzt auch seine Deckenreparaturen ausführen, das Ausfräsen von Nuten, das Abfräsen von Markierungen und das Herstellen von Anschlüssen.With his excavator equipped with the device described here, the road builder can now also carry out ceiling repairs, milling grooves, milling markings and making connections.

Der Unternehmer kann aufgrund der Tatsache, daß der Bagger mit seinem Ausleger über Hindernisse hinweg arbeiten kann, jetzt Fugenschneid- und Fräsarbeiten an Stellen ausführen, wo bisher Geräte nicht eingesetzt werden konnten. Abgesehen von den technischen Möglichkeiten, die dieses Anbaugerät bietet, spart der Unternehmer gegenüber den bisherigen Methoden die Anschaffung von 2 bzw. 3 sehr viel teureren, selbstfahrenden Geräten.Due to the fact that the excavator can work with its boom over obstacles, the contractor can now carry out joint cutting and milling work in places where equipment could not previously be used. Apart from the technical possibilities that this attachment offers, the entrepreneur saves the purchase of 2 or 3 much more expensive, self-propelled devices compared to the previous methods.

Bisher wurden Fugenschneidarbeiten mit Diamantfugenschneidern ausgeführt. Das hier beschriebene Gerät ist mit einer Frässcheibe ausgerüstet. Diese besteht aus einer Stahlscheibe, auf die Halter für Rundschaftmeißel in einem solchen seitlichen Winkel aufgeschweißt werden, daß die in diese Halter hineingesteckten Rundschaftmeißel die Stahlscheibe freischneiden. Die beiden Hälften der Stahlscheibe werden auf die Flansche der Antriebswelle aufgeschraubt (Fig. 1, Ziffer 8). Die Arbeit mit der Frässcheibe hat im Vergleich zu einer Diamantscheibe folgende Vorteile: 1. die Verschleißkosten von einem Satz Rundschaftmeißel betragen nur 1/jo soviel wie die Verschleißkosten beim Einsatz von Diamantfugenschneidern. Hier in der Bundesrepublik betragen die Kosten für einen Satz Rundschaftmeißel DM 300,-. Die Standzeit bei einer Schneidtiefe von 15 cm beträgt ca. 1500 m. Das sind Verschleißkosten von ca. DM -,20 pro laufenden Meter. Eine Diamantscheibe in der Größe für eine Schnittiefe von 15 cm kostet ca. DM 1.200,-. Die Standzeit beträgt ca. 600 m. Das sind Verschleißkosten pro laufenden Meter von ca. DM 2,-. 2. Beim Diamantfugenschneider wird für die Kühlung der Diamantscheibe Wasser benötigt. Die Frässcheibe benötigt keine Kühlung durch Wasser. Der Unternehmer spart also die Kosten und den Zeitaufwand für die Wasserbeschaffung und die Wasservorhaltung. 3. Mit der Diamantscheibe wird eine Fuge von 3-5 mm Breite geschnitten. Die Folge ist, daß sehr oft beim Herausnehmen der geschnittenen Fläche mit dem Bagger Verklemmungen auftreten. Die Fuge der mit Rundschaftmeißeln ausgerüsteten Frässcheibe beträgt mindestens 3 cm. Es tritt deshalb hier keine Verklemmung auf.So far, joint cutting work has been carried out with diamond joint cutters. The device described here is equipped with a milling disc. This consists of a steel disc on which holders for picks are welded at such a lateral angle that the picks inserted into these holders cut out the steel disc. The two halves of the steel disc are screwed onto the flanges of the drive shaft (Fig. 1, number 8). Working with the milling disc has the following advantages compared to a diamond disc: 1. The wear costs of a set of round shank chisels are only 1 / jo as much as the wear costs when using diamond joint cutters. Here in the Federal Republic, the cost of a set of round chisels is DM 300. The tool life at a cutting depth of 15 cm is approx. 1500 m. That is wear costs of approx. DM -, 20 per running meter. A diamond wheel in the size for a cutting depth of 15 cm costs approx. DM 1,200. The service life is approx. 600 m. That is wear costs per running meter of approx. DM 2, -. 2. With the diamond joint cutter, water is required to cool the diamond disc. The milling disc does not require water cooling. The entrepreneur thus saves the costs and the time required for water procurement and water supply. 3. A gap of 3-5 mm width is cut with the diamond disc. The result is that jamming occurs very often when the excavated area is removed with the excavator. The joint of the milling disc equipped with round shank chisels is at least 3 cm. There is therefore no jamming here.

Hydrostatisch oder hydraulisch angetriebene Bagger, Baggerlader und Frontlader können fräsen bzw. schneiden, indem sie vorwärtsfahren, da sie entweder von sich aus oder nach Einbau eines Mengenreglers langsam genug fahren können, um Schneid- und Fräsarbeiten ausführen zu können (etwa 100-200 Meter pro Stunde). Das beschriebene Gerät kann deshalb am Rahmen oder am Ausleger, bzw. Arm dieser Maschinen angebracht werden. Es ist allerdings vorteilhafter, es am Ausleger bzw. Arm anzubringen, als am Rahmen. Bei den Hydraulikbaggern besteht dadurch die Möglichkeit, daß der Bagger auf der Straße fahren und auf dem Fußweg fräsen und schneiden kann, bzw. über Hindernisse hinweg Fräs- und Schneidarbeiten ausführen kann. Bei dem Frontlader besteht eine viel bessere Sicht des Fahrers auf das hier beschriebene Gerät, als wenn es hinten am Rahmen angebracht wird. Außerdem wird in beiden Fällen die zusätzliche hydraulische Hubeinrichtung gespart, die sonst das hier beschriebene Gerät bewegen müßte. Bei mechanisch angetriebenen Baggern und Baggerladern kann das hier beschriebene Gerät nur am Ausleger angebracht werden, da bei allen auf dem Markt befindlichen Geräten die Vorschubgeschwindigkeit im ersten Gang zu hoch ist. Die Baggerlader arbeiten folgendermaßen: Der Ausleger mit dem hier beschriebenen Gerät wird in äußerste Reichweite gebracht. Dann wird die Fräswalze bzw. Frässcheibe in die Straßenoberfläche gepreßt und anschließend der Ausleger an die Maschine herangezogen bis zum maschinennächsten Punkt. Um kalt fräsen zu können, ist es erforderlich, möglichst viel Gewicht auf der Fräswalze bzw. Frässcheibe zu haben. Gleichzeitig muß aber eine Einrichtung vorhanden sein, die die gewünschte Frästiefe sicherstellt. Eine solche Abstütz- und Tiefenverstelleinrichtung befindet sich an dem hier beschriebenen Gerät. Das wesentliche an dieser Abstütz- und Tiefenverstelleinrichtung ist, daß sie freischwingend um die Antriebswelle gelagert ist. Nur dadurch ist es möglich, daß die Rollen dieser Abstütz- und Tiefenverstelleinrichtung ständig auf die Straßenoberfläche gepreßt und damit die Fräswalze bzw. die Frässcheibe in der gewünschten Tiefe in die Straßenoberfläche gepreßt werden können, während der Ausleger von der äußersten Reichweite bis zum maschinennächsten Punkt gebracht wird.Hydrostatically or hydraulically driven excavators, backhoe loaders and front loaders can mill or cut by driving forward, because they can either drive on their own or after installing a volume controller slowly enough to carry out cutting and milling work (about 100-200 meters per hour). The device described can therefore be attached to the frame or to the boom or arm of these machines. However, it is more advantageous to attach it to the boom or arm than to the frame. With the hydraulic excavators there is the possibility that the excavator can drive on the road and mill and cut on the footpath, or can carry out milling and cutting work over obstacles. The front loader gives the driver a much better view of the device described here than if it were attached to the rear of the frame. In addition, the additional hydraulic lifting device is saved in both cases, which would otherwise have to move the device described here. In the case of mechanically driven excavators and backhoe loaders, the device described here can only be attached to the boom, since the rate of advance in first gear is too high for all devices on the market. The backhoe loaders work as follows: The boom with the device described here is brought within the maximum reach. Then the milling drum or milling disk is pressed into the road surface and then the boom is pulled towards the machine to the point closest to the machine. In order to be able to mill cold, it is necessary to have as much weight as possible on the milling drum or milling disk. At the same time, a device must be available to ensure the desired milling depth. Such a support and depth adjustment device is located on the device described here. The essential thing about this support and depth adjustment device is that it is freely suspended around the drive shaft. This is the only way that the rollers of this support and depth adjustment device can be pressed constantly onto the road surface and thus the milling drum or the milling disk can be pressed into the road surface at the desired depth, while the boom is brought from the outermost reach to the point closest to the machine becomes.
