Description

Kombiniertes Straßenfräs-Fugenschneid-Anbaugerät für Hydraulikbagger, Baggerlader und FrontladerCombined road milling joint cutting attachment for hydraulic excavators, backhoe loaders and front loaders

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 loader.

Es gibt selbstfahrende Straßenfräsen und Anbau-Straßenfräsen für Traktoren, und es gibt selbstfahrende Fugenschneider mit Diamantscheiben. Es gibt eine Anzahl von Anbaugeräten für Bagger, Baggerlader und Frontlader für verschiedene Einsatzzwecke, aber nicht für Fräsen und Fugenschnei- den. 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. 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 surface milling machines for tractors, and there are self-propelled floor saws with diamond discs. There are a number of attachments for excavators, backhoe loaders and front loaders for a variety of applications, but not for milling and Fu g enschnei- to. The novelty of 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 loader. With this device, every hydraulic excavator, backhoe loader and front loader can now also be used as a road milling machine or as a joint cutter. This makes these devices more universal and economical to use. At almost every deep and road construction site there is an excavator, backhoe loader or front loader, which is often underutilized. During this time, these devices can use the combined surface-mounted road milling cutter to perform the joint cutting and road milling work that occurs on the site. The milling drum must be replaced within a few minutes against the milling disc and vice versa. By installing a trench cutter, in which the drive wheel for the trench cutter 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 machine.

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 Fräsarbeit 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 pipe builders can cut the joints on their construction sites with this device first with the milling disc. After digging the trench, laying the pipes, the trench backfilled and the substructure material has been introduced, they can then mill the edges with the milling drum to 10 to 20 cm wide 2 - 3 cm deep, so that a better bond between the old and the new ceiling is made. Cable makers no longer need to cut twice on footpaths where most cables are routed. Many footpaths are only provided with a thin wear layer of about 2 cm. Underneath is a bituminous gravel layer of approx. 8 - 10 cm. The device described here can mill out the entire wear and bituminous layer with the milling drum in a single 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 walk on footpaths are too light and do not have enough power. Large milling machines can not drive on footpaths. In the device described here such work is possible because the excavator drive on the road and at the same time with swung-out boom on which the device described here is mounted, can perform the milling work on the footpath. Then the ditch can be dug with the trencher. In addition, in this case, another rationalization effect, namely that the finely shredded ceiling material can be used again as a substructure for the new wear blanket.

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. 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.The road builder can now carry out his ceiling repairs with his excavator equipped with the device described here, the milling of grooves, the milling of markings and the making of connections. The operator can now perform joint cutting and milling work in places where equipment could not be used due to the fact that the excavator can work with its boom over obstacles. Apart from the technical possibilities offered by this attachment, 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 Vor-. teile: 1. die Verschleißkosten von einem Satz Rundschaftmeissel betragen nur 1/10 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. 1.500 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 with a Milling disc equipped. This consists of a steel disc, are welded to the holder for round shank chisel in such a lateral angle, that the inserted into this holder round shank chisel free the steel disc. The two halves of the steel disc are screwed onto the flanges of the drive shaft (Fig. 1, item 8). The work with the milling disc has the following advantages compared to a diamond disc. Parts: 1. The wear cost of one set of pick bits amount to only 1/10 as much as the wear costs when using diamond joint cutters. Here in the Federal Republic the costs for a set of round chisel DM 300, -. The service life with a cutting depth of 15 cm is approx. 1,500 m. That is wear costs of about DM -, 20 per running meter. A diamond disc in size for a depth of cut of 15 cm costs about DM 1,200, -. The service life is approx. 600 m. These are wear costs per running meter of about DM 2, -. 2. The diamond joint cutter requires water to cool the diamond wheel. The milling disc does not require cooling by water. The entrepreneur thus saves the costs and the time spent on water procurement and water conservation. 3. The diamond wheel is used to cut a gap of 3 - 5 mm width. The result is that very often occur when removing the cut surface with the excavator deadlocks. The joint of the rounding chisel equipped milling disc is at least 3 cm. It therefore occurs here no jamming.

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 powered excavators, backhoe loaders and front loaders can mill or cut by moving forward, either on their own or, after installing a flow regulator, driving slowly enough to perform cutting and milling work (about 100-200 meters per hour) Hour) The device described can therefore be mounted on the frame or on 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 hydrau As a result, it is possible for the excavators to drive on the road and mill and cut on the sidewalk, or to 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 is mounted on the back of the frame. In addition, the additional hydraulic lifting device is saved in both cases, which would otherwise 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, as the speed 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 into extreme reach. Then the milling drum or milling disc is pressed into the road surface and then the boom is used on the machine up to the machine next point. In order to be able to mill cold, it is necessary to have as much weight as possible on the milling drum or milling disc. At the same time, however, there must be a device which ensures the desired milling depth. Such a support and Tiefenverstelleinrichtung is located on the device described here. The essential thing about this support and Tiefenverstelleinrichtung is that it is mounted freely swinging around the drive shaft. Only thereby it is possible that the rollers of this jacking and Tiefenverstelleinrichtung constantly pressed onto the road surface and thus the milling drum or the milling disc can be pressed into the desired depth in the road surface, while the boom brought from the outermost range to the machine next point becomes.
