Description
Die vorliegende Erfindung betrifft ein fahrbares materialabtragendes Bodenflächenbearbeitungsgerät gemäss Oberbegriff des Patentanspruches 1.The present invention relates to a mobile material-removing Soil cultivation device according to the preamble of patent claim 1.
Bodenflächenbearbeitungsgeräte werden von der Anmelderin bereits seit Jahrzehnten gefertigt und vertrieben. Es handelt sich hierbei immer um Geräte, bei denen ein oder zwei Rotortrommeln in rotierende Bewegung gesetzt werden. Die Rotortrommeln sind als Käfige gestaltet, auf deren Käfigstäbe eine Vielzahl von Bearbeitungselementen aufgereiht sind. Diese Bearbeitungselemente weisen eine Durchgangsbohrung auf, deren Durchmesser etliches grösser als der Durchmesser der Käfigstäbe ist. Durch die Rotation des Rotorkäfiges werden die Bearbeitungselemente nach aussen geschleudert und treffen hammerartig auf die zu bearbeitende Bodenfläche auf. Solche Geräte haben sich in vielen Anwendungen seit Jahren bewährt. Insbesondere werden hiermit verunreinigte Deckschichten auf Betonböden abgetragen, aber auch ganze Landebahnen auf Flughäfen bearbeitet, um die Griffigkeit der Landepiste zu erhöhen. Die Struktur einer solchen bearbeiteten Oberfläche ergibt ein Schlag- und Kratzbild. Insbesondere bei der Bearbeitung von betonierten Flächen wurden dadurch auch immer ganze Kiesel losgeschlagen. Ferner führte die Behämmerung der Bodenfläche oftmals auch zu Schäden an Rohrleitungen, die im Betonboden eingelegt waren, wie insbesondere Bodenheizungen und elektrische Leitungen. Zudem betrug die Abtragstiefe in einem Durchgang kaum mehr als 1-3 mm.Soil cultivation devices have been used by the applicant for decades manufactured and distributed. It is about this always around devices where one or two rotor drums are rotating Movement. The rotor drums are as Cages designed, on the cage bars a variety of processing elements are lined up. These editing elements have a through hole, the diameter of which is quite a bit is larger than the diameter of the cage bars. Through the rotation the machining elements of the rotor cage hurled outside and hit the one to be worked like a hammer Floor area. Such devices have appeared in many Applications proven for years. In particular, hereby contaminated surface layers removed on concrete floors, however Even entire runways at airports are machined to improve grip to increase the landing strip. The structure of such processed surface gives an impact and scratch image. Especially when working on concrete surfaces Whole pebbles are always struck off. Furthermore led the twisting of the floor surface often also causes damage Pipes that were inserted in the concrete floor, such as in particular Floor heating and electrical lines. In addition, was the removal depth in one pass is hardly more than 1-3 mm.
Flächenbearbeitungsgeräte sind als Weiterentwicklungen beispielsweise aus der EP-A-0'098'798, EP-A-0'241'417 oder US-A-3'063'690 bekannt. Dem gegenüber ist aus der DE-A-20'12'673 eine Strassenfräse bekannt, die mit zwei getriebenen Rotorwalzen bestückt ist, in denen Bearbeitungsstifte eingelassen sind. Das entsprechende Bearbeitungsbild ist ein reines Kratzbild. Das letztgenannte Gerät hat sich insbesondere zur Entfernung von Strassenmarkierungen und Asphaltunebenheiten bewährt. Auf Betonflächen lässt sich ein solches Gerät nicht einsetzen.Tillage equipment are as Further developments, for example from EP-A-0'098'798, EP-A-0'241'417 or US-A-3'063'690 are known. Is opposite from DE-A-20'12'673 a road milling machine known with is equipped with two driven rotor rollers, in which machining pins are let in.

Es sind dies Geräte, die insbesondere zum Abziehen von Parkettböden entwickelt worden sind.Furthermore, devices with a similar structure from the patents US-A-2'041'140, US-A-1'947'136 and US-A-2'014'626 known, with two rotor rollers arranged side by side work and equipped with abrasives or brushes are. These are devices that are particularly suitable for pulling off of parquet floors have been developed.
Ferner sind auch Nutenfräsmaschinen bekannt, die einen ähnlichen Aufbau aufweisen. Diesbezüglich wird insbesondere auf die US-A-2664281 verwiesen.Slot milling machines are also known which have a similar one Have structure. In this regard, in particular refer to US-A-2664281.
Ferner ist auch noch aus der SU-A-753'654 eine Schleifmaschine bekannt geworden, die zur Bearbeitung der Oberflächen von Steinplatten geeignet ist. Dieses Gerät arbeitet über die gesamte Arbeitsfläche flächendeckend mit zwei Wellen, auf denen je mehrere Keramikschleifscheiben versetzt zueinander angeordnet aufgereiht sind. Ein solches Gerät ergibt eine besonders feine Oberflächenstruktur und eine minimale Abtragungstiefe.Also from SU-A-753'654 is a grinding machine have become known for the machining of the surfaces of Stone slabs is suitable. This device works across the entire Work surface covering two shafts on which several ceramic grinding disks offset from each other are lined up. Such a device makes a special one fine surface structure and minimal removal depth.
Letzlich ist aus der DE-A-2'151'190 ein Flächenbearbeitungsgerät gemäss Oberbegriff des Patentanspruches 1 bekannt. Dieses zum Rillen von Betonplatten konzipierte Gerät weist eine Achse auf, die beidseitig im Gehäuse gelagert ist und auf dem eine von aussen beidseitig angetriebene Hohlwelle gedichtet und mit Wälzlagern versehen, läuft.Ultimately, DE-A-2'151'190 is a surface processing device according to the preamble of claim 1 known. This device, designed for grooving concrete slabs, shows an axis, which is supported on both sides in the housing and on which seals a hollow shaft driven from the outside on both sides and provided with rolling bearings, runs.
Die vorliegende Erfindung hat sich zur Aufgabe gestellt, ein Gerät der eingangs genannten Art zu schaffen, das einen ruhigeren Lauf als die Geräte mit hämmernder Arbeitsweise ergibt und eine extrem grosse Abtragstiefe in einem Durchgang ermöglicht, wobei eine in achsialer und radialer Richtung absolut korrekte Lagerung und einfache, steckbare Auswechselbarkeit der Rotortrommel gewährleistet sein muss.The present invention has for its object a To create device of the type mentioned that a quieter Run as the devices with hammering results and enables an extremely large removal depth in one pass, one in the axial and radial directions absolutely correct storage and simple, pluggable interchangeability the rotor drum must be guaranteed.
Diese Aufgabe löst ein Gerät mit den Merkmalen des Patentanspruches 1.This object is achieved by a device with the features of the patent claim 1.
Das ungewöhnliche der erfindungsgemässen Lösung besteht darin, dass die Bearbeitungselemente, in diesem Fall Diamanttrennscheiben, die bisher lediglich zum Schneiden eingesetzt wurden, nun für eine flächige Bearbeitung zum Einsatz kommen.The unusual of the solution according to the invention exists in that the editing elements, in this case Diamond cutting discs that were previously only used for cutting have now been used for surface processing Come into play.

Die Ansicht von unten des fahrbaren Bodenflächenbearbeitungsgerät
zeigt dessen wesentlichsten Bestandteile. Der eigentliche
Antrieb bestehend aus einem Motor und die Transmissionsmittel,
nämlich die Keilriemen, sind hier als erfindungsunwesentlich
weggelassen. Auch die Deichsel mit der Bezugszahl 0
ist nur noch im Ansatz erkennbar. Das gesamte fahrbare Gerät
steht auf seinen vier Laufrädern 1. Die beiden in Schubrichtung
vorderen Räder 1 sind auf einer starren Achse 2 zwischen
den beiden Seitenwänden des Gehäuses 4 gelagert. Die beiden in
Schubrichtung hinteren Räder 1 sind auf einer hinteren, höhenverschwenkbaren
Achse 3 montiert. Zwischen den beiden Seitenwänden
des Gehäuses 4 lagert die Rotorwelle 5. Auf der Rotorwelle
5 wiederum lagert die in Figur 2 im Detail dargestellte
Rotortrommel. Antriebsseitig ist in der Seitenwand des Gehäuses
4 eine Bohrung angebracht, in der ein Lagergehäuse 6
passt, welches selber wiederum mittels Schrauben an jeder
Seitenwand angeschraubt ist. Die Rotorwelle 5 hält mit Passsitz
in den beiden Kugellagern 8 und durchsetzt das Lagergehäuse 7,
so dass ein Zapfen verbleibt, auf dem ein Mehrfachkeilriemenrad
Platz findet. Mittels einer achsialen Lagerscheibe 9, auf
die eine Kontermutter 10 drückt, ist die Rotorwelle 5 achsial
gesichert.The bottom view of the mobile tillage implement
shows its most essential components. The actual
Drive consisting of a motor and the transmission means,
namely the V-belts are not essential to the invention here
omitted. Also the drawbar with the reference number 0
is only recognizable in the beginning. The entire mobile device
stands on its four wheels 1. The two in the direction of thrust
front wheels 1 are on a rigid axle 2 between
the two side walls of the
Auf der gegenüberliegenden Seite des Gehäuses lagert das
andere Ende der Rotorwelle 5 steckbar in einem Kugellager 13,
welches in einem zweiten Lagergehäuse 12 gesichert gehalten
ist, welches selber wiederum in einem wegnehmbaren Deckel 11
befestigt ist. Im Zapfen 14 der Rotorwelle 5, der im Kugellager
13 zu liegen kommt, ist eine Ringnut 15 eingelassen, in
dem ein O-Ring eingelegt ist. Will man den gesamten Rotor auswechseln,
so löst man den Deckel 11, in dem das Lagergehäuse
12 befestigt ist, und zieht das Lager direkt vom Rotorzapfen
14 der Rotorwelle 5 herunter. Erst wenn man den Konterring 29,
der auf dem Aussengewinde 32 der Rotorwelle 5 aufgeschraubt
ist, entfernt hat, lässt sich die gesamte Trommel von der
Rotorwelle abziehen.This is stored on the opposite side of the housing
other end of the
Die Rotortrommel besteht im wesentlichen aus einer Hohlwelle
20, auf der einseitig ein fester Flansch 21 aufgeschweisst
ist. Der feste Flansch 21 weist gleichmässig am Umfang verteilte
Gewindelöcher und Durchgangslöcher auf. In den Gewindelöchern
sind Haltestäbe 22 eingeschraubt, die parallel zur
Hohlwelle über dessen gesamte Länge hinaus sich erstrecken.
Auf diesen Haltestäben 22 sind in abwechselnder Reihenfolge
eine Vielzahl von Diamanttrennscheiben 23 und Distanzringen 24
aufgereiht. Die maximale Arbeitsbreite des Rotors ist folglich
etwas geringer als die Länge der Hohlwelle 20. Sowohl die
Diamanttrennscheiben 23 als auch die Distanzringe 24 müssen
selbstverständlich entsprechende Bohrungen aufweisen, durch
die die Haltestäbe 22 hindurchgehen. Auf der Gegenseite wird
auf der Hohlwelle 20 ein Konterflansch 25 aufgesetzt, der
mittels Mutter 28 unter Zwischenlage von Federscheiben 27 das
Paket von Diamanttrennscheiben und Distanzringen fest zusammenpresst.
Der Konterflansch 25 weist zusätzlich noch eine
Verdrehsicherung 26 in Form eines Stiftes auf, der eine verdrehsichere
Lagerung des Konterflansches 25 auf der Hohlwelle
20 garantiert. Wie bereits erwähnt, wird mittels einem Konterring
21 die Hohlwelle 20 auf der Rotorwelle 5 achsial gesichert.
Auch antriebsseitig ist die Hohlwelle 20, sowohl bezüglich
achsialen, wie auch'radialen Bewegungen, bezüglich der
Rotorwelle 5 gesichert. Hierzu dient ein Anschlagsflansch 34,
welcher mittels einem Keil 35 gesichert ist. Im Anschlagsflansch
34 sind Mitnehmerbolzen 36 mittels Pressitz gehalten,
deren vorstehendes freies Ende im festen Flansch 21 auf der
Hohlwelle 20 steckbar Aufnahme finden. Die Verwendung von Diamanttrennscheiben
verlangt sowohl eine achsiale, wie auch
radiale spielfreie Lagerung der gesamten Trommel. Nur so kann
sicher gestellt werden, dass während der Arbeit auf die Trennscheiben
keine Kräfte einwirken, die zu deren Bruch führen
würden. Eine solche spielfreie Lagerung ist nicht absolut einfach
zu erreichen, wenn andererseits aber eine einfach steckbare
Auswechselbarkeit der Rotortrommel gewährleistet sein
soll. Ein Teilproblem stellt die Lagerung des Rotorzapfens 14
im Kugellager 13 dar. Hier wurde das Spiel durch den Einbau
eines O-Ringes 16 aufgefangen. Um die Reibungskräfte der Hohlwelle
20 auf der Rotorwelle 5 zu verringern, entsprechen lediglich
die Endbereiche 30 der Rotorwelle 5 einem Gleitsitz,
während der gesamte mittlere Bereich zwischen den beiden Endbereichen
30 einen kleineren Durchmesser aufweist, und somit
berührungslos die Hohlwelle 20 durchsetzt.The rotor drum consists essentially of a
Erste Messungen mit dem erfindungsgemässen Gerät haben gezeigt, dass in einem erstmaligen Durchgang bereits eine Abtragstiefe bis zu 15 mm erreichbar ist. Entsprechend lassen sich mit einem solchen Flächenbearbeitungsgerät auch Nuten fräsen. Insbesondere für die Erstellung von relativ breiten Nuten, für die bisher kaum eine brauchbare Vorrichtung bestand, wird hier eine Lösung angeboten. Solche breite Nuten sind beispielsweise zur Verlegung von Leitsystemen in vollautomatischen Hohlregallagern erforderlich.First measurements with the device according to the invention have shown that in a first pass there is already a depth of cut can be reached up to 15 mm. Leave accordingly grooves with such a surface treatment device milling. Especially for the creation of relatively wide grooves, for which there was hardly a usable device so far offered a solution here. Such wide grooves are, for example for laying control systems in fully automatic Hollow rack storage required.
