Abstract

The hydraulic milling tool (0), for attachment to a construction or mining machine, has at least one cutting roller (11), at least one flywheel (12) to take up kinetic energy, and at least one hydraulic motor (6) to rotate the cutting roller and flywheel. The flywheel is rotated at a higher rotary speed than the cutting roller, to give the cutter an increased moment of inertia. A gearing (2) sets a fixed rotary speed ratio between them.

Description

Die vorliegende Erfindung betrifft eine Hydraulikfräse zum Anbau an die Ausrüstung einer Bau- oder Bergbaumaschine, mit mindestens einer Schneidwalze, mindestens einer Schwungmasse zur Aufnahme kinetischer Energie und mindestens einem hydraulischen Motor zum rotatorischen Antreiben der Schneidwalze und der Schwungmasse.The present invention relates to a hydraulic milling machine for attachment to the Equipment of a construction or mining machine, with at least one Cutting roller, at least one flywheel for receiving kinetic Energy and at least one hydraulic motor for rotary Driving the cutting roller and the flywheel.

Derartige Hydraulikfräsen sind vielseitig nutzbar. So werden sie unter anderem zum Abbruch von Bauwerken, zum Anlegen von Gräben, zum Streckenvortrieb oder in der über- und untertägigen Gewinnung eingesetzt. Für den jeweiligen Einsatz werden Hydraulikfräsen in unterschiedlichen Leistungsklassen und mit geeigneten Zahnbestückungen angeboten. Eine gattungsgleiche Hydraulikfräse zum Anbau an die Tieflöffelausrüstung eines Standard-Baggers ist aus der der US 6 438 874 bekannt.Such hydraulic milling machines are versatile. So they become, among others for the demolition of structures, for the creation of ditches, for the drifting of roads or used in over and underground mining. For the respective The use of hydraulic milling machines in different performance classes and with offered suitable tooth fillings. A generic hydraulic tiller for attachment to the bucket equipment of a standard excavator is from the US 6,438,874.

Häufig arbeitet die Fräse in inhomogenen Material. Dies kann etwa in Grenzbereichen von unterschiedlichen Gesteinsschichten oder beim Rückbau von Stahlbeton der Fall sein. Beim Vorschub durch solches Material ist die Fräse schlagartigen Belastungen ausgesetzt, welche ihr Antriebsmoment übersteigen können; in diesem Fall droht die Fräse zu blockieren.Often the router works in inhomogeneous material. This can be about in Boundary areas of different rock strata or during dismantling of reinforced concrete to be the case. When feeding through such material is the Tiller exposed to sudden loads, which their driving torque can exceed; In this case, threatens to block the router.

Aus diesem Grunde sollte die rotierende Schneidwalze ein möglichst hohes Trägheitsmoment aufweisen. Hierdurch erhält die rotierende Schneidwalze eine hohe kinetische Energie, welche ihr bei der Überwindung von Widerstandsspitzen behilflich ist. Die installierte Antriebsleistung der Fräse kann dadurch vergleichsweise gering ausfallen. For this reason, the rotating cutting roller should be as high as possible Have moment of inertia. This gives the rotating cutting roller a high kinetic energy, which helps you to overcome resistance peaks is helpful. The installed drive power of the mill can thereby comparatively low.

Das vorgenannte Patent lehrt unter anderem, das Trägheitsmoment der Schneidwalze dadurch zu steigern, daß auf ihrer Innenseite Schwungmassen angeordnet werden. Nachteilig bei dieser Lösung ist, daß mit dem Trägheitsmoment der Schneidwalze auch die Gesamtmasse der Hydraulikfräse unverhältnismäßig ansteigt. Hierdurch wird in dem vorliegendem Einsatzbeispiel der nutzbare Arbeitsbereich der Fräse verkleinert, da die Standsicherheit des Baggers auch bei voller Ausladung stets gewährleistet werden muß.The aforementioned patent teaches, among other things, the moment of inertia of To increase cutting roller thereby that on its inside flywheel masses to be ordered. The disadvantage of this solution is that with the Moment of inertia of the cutting roller and the total mass of the hydraulic cutter disproportionately increases. This is in the present application example the usable working area of the mill is reduced because the stability of the mill Baggers must always be guaranteed even at full load.

Aufgabe der vorliegenden Erfindung ist es daher, eine Hydraulikfräse zu schaffen, deren Schneidwalzen-Trägheitsmoment in einem günstigen Verhältnis zum Gesamtgewicht der Hydraulikfräse steht.Object of the present invention is therefore to a hydraulic milling machine create their cutting roller moment of inertia in a favorable ratio to the total weight of the hydraulic cutter stands.

Diese Aufgabe wird von einer Hydraulikfräse eingangs genannter Art gelöst, deren Schwungmasse mit einer höheren Winkelgeschwindigkeit als die Schneidwalze rotiert.This object is achieved by a hydraulic milling machine of the type mentioned, their momentum with a higher angular velocity than the Cutting roller rotates.

Der Vorteil dieser Lösung gegenüber dem Stand der Technik ist eindeutig: Eine proportionale Steigerung der Winkelgeschwindigkeit der Schwungmasse hat eine quadratische Steigerung der in der Schwungmasse gespeicherten kinetischen Energie zur Folge, dagegen bewirkt eine proportionale Steigerung des Trägheitsmoments der Schwungmasse lediglich eine lineare Steigerung der Energie. Das höhere Drehzahlniveau der Schwungscheibe wirkt sich dagegen nicht direkt auf die Gesamtmasse der Fräse aus.The advantage of this solution over the prior art is clear: a proportional increase in the angular velocity of the flywheel has a quadratic increase in the stored in the flywheel kinetic energy, however, causes a proportional increase the moment of inertia of the flywheel only a linear increase of Energy. The higher speed level of the flywheel affects it not directly on the total mass of the cutter.

Technisch realisieren lassen sich unterschiedliche Winkelgeschwindigkeiten von Schneidwalze und Schwungmasse mit Hilfe eines Getriebes, welches die beiden Winkelgeschwindigkeiten in ein festes Verhältnis setzt. Unter festem Verhältnis ist in diesem Zusammenhang zu verstehen, daß sich das Verhältnis der Winkelgeschwindigkeiten nicht ungewollt durch Betriebseinflüsse wesentlich ändert. Ein Schlupf des Getriebes von bauartbestimmter Größe kann nicht vollständig ausgeschlossen werden. Auch ist es denkbar, ein Getriebe mit variablen Übersetzungsverhältnis zu verwenden, um beispielsweise die Charakteristik der Fräse entweder in Richtung einer guten Anfahr- und Bremsdynamik einerseits oder zu Gunsten eines hohen Energiespeichervermögens andererseits zu beeinflussen. Technically realize different angular velocities of Cutting roller and flywheel with the help of a transmission, which the sets both angular velocities in a fixed relationship. Under firm Ratio is to be understood in this context that the ratio The angular velocities are not unintentional due to operational influences changes. A slip of the gearbox of design size can not be completely excluded. It is also possible to use a gearbox variable ratio to use, for example, the Characteristic of the router either in the direction of a good start-up and Braking dynamics on the one hand or in favor of a high energy storage capacity on the other hand.

Im Allgemeinen stimmt die Nenndrehzahl des Hydraulikmotors, bei welcher dieser einen guten Wirkungsgrad erreicht, nicht mit den gewünschten Drehzahlen der Schwungmasse oder der Schneidwalze überein. Daher wird die Schwungmasse beziehungsweise die Schneidwalze im Allgemeinen nicht direkt angetrieben werden. So wird meist neben dem ersten Getriebe, welches Schneidwalze und Schwungmasse verbindet, ein weiteres Getriebe notwendig, welches beispielsweise Motor und Schneidwalze verbindet. Um die Hydraulikfräse möglichst kompakt aufzubauen und zielverfolgend Masse einzusparen, schlägt eine Weiterbildung der Erfindung vor, beide Getriebe in ein Getriebe zu integrieren und so auch die Winkelgeschwindigkeit des hydraulischen Motors in festes Verhältnis zu denen der Schneidwalze und der Schwungmasse zu setzen.In general, the rated speed of the hydraulic motor is correct at which this achieved a good efficiency, not with the desired Speeds of the flywheel or the cutting roller match. Therefore, the Flywheel or the cutting roller generally not directly are driven. So is usually next to the first gear, which Cutting roller and flywheel connecting, another gear necessary which connects for example motor and cutting roller. To the hydraulic milling machine to build up as compact as possible and to save mass in a targeted manner, proposes a development of the invention, both transmissions in a transmission integrate and so does the angular velocity of the hydraulic motor in fixed relationship to those of the cutting roller and the flywheel too put.

Für diese Bewegungsaufgabe ist ein Standrädergetriebe mit Stirnradverzahnung gut geeignet.For this movement task is a standard gearbox with spur gear teeth well suited.

Eine besonders vorteilhafte Ausführung der Erfindung ist eine mit den Merkmalen des Anspruches 5. Eine mögliche Konzeption einer Hydraulikfräse mit den Merkmalen des Anspruchs 5 soll nun anhand der Figur näher erläutert werden. Die Figur zeigt:

A particularly advantageous embodiment of the invention is one with the features of claim 5. A possible concept of a hydraulic milling cutter with the features of claim 5 will now be explained in more detail with reference to the figure. The figure shows:
FIG. 1:
Symbolic structure of a hydraulic milling machine according to claim 5 in longitudinal section.

Die tragende Struktur der Hydraulikfräse 0 bildet ein Gehäuse 1, in welchem der gesamte Antriebsstrang untergebracht ist. Kern des Antriebsstrangs bildet ein Getriebe 2, welches über einen Antrieb 3 und zwei Abtriebe 4, 5 verfügt. Der Antrieb 3 der Hydraulikfräse 0 erfolgt über zwei Hydraulikmotore 6, welche koaxial auf einer gemeinsamen Motorwelle 7 angeordnet sind. Ebenfalls auf dieser Motorwelle 7 angeordnet ist ein Antriebsrad 8.The supporting structure of the hydraulic mill 0 forms a housing 1, in which the entire drive train is housed. Core of the powertrain forms Transmission 2, which has a drive 3 and two outputs 4, 5. The Drive 3 of the hydraulic cutter 0 via two hydraulic motors 6, which are arranged coaxially on a common motor shaft 7. Also on arranged this motor shaft 7 is a drive wheel. 8

Neben dem Antriebsrad 8 befinden sich zwei Nachbarräder 9, 10, die beide mit dem Antriebsrad 8 kämmen. Jedes der Nachbarräder 9, 10 begründet einen Stirnradzug, der jeweils an einem der beiden Abtriebe 4, 5 endet. Dem erstem Abtrieb 4 ist eine Schneidwalze 11 zugeordnet, dem zweiten Abtrieb 5 eine Schwungmasse 12.In addition to the drive wheel 8 there are two neighboring wheels 9, 10, both with the drive wheel 8 comb. Each of the neighboring wheels 9, 10 establishes a Stirnradzug which ends at one of the two outputs 4, 5 respectively. The first Output 4 is associated with a cutting roller 11, the second output 5 a Flywheel 12.

Die Schneidwalze 11 setzt sich aus zwei Halbschalen 11a, 11b zusammen, die beiderseits des Gehäuses 1 auf einer gemeinsamen Schneidwalzenachse 13 angeordnet sind. Auf der Außenseite der Halbschalen 11a, 11b befinden sich Zähne 14, deren Beschaffenheit und geometrische Lage und Ausrichtung sich nach dem Einsatzzweck der Hydraulikfräse 0 richtet.The cutting roller 11 is composed of two half-shells 11 a, 11 b, the on both sides of the housing 1 on a common cutting roller axis thirteenth are arranged. On the outside of the half-shells 11a, 11b are located Teeth 14, their texture and geometrical position and alignment directed according to the intended use of the hydraulic cutter 0.

Die Schwungmasse setzt sich aus zwei Teilmassen 12a, 12b zusammen, die beiderseits des Getriebes 2 auf einer gemeinsamen Schwungmassenachse 15 angeordnet sind. Die Schwungmassenachse 15 ist mit einer Verzahnung versehen, die als Schwungmassen-Abtriebsrad 17 dient.The flywheel is composed of two sub-masses 12a, 12b, the on both sides of the transmission 2 on a common flywheel mass 15 are arranged. The flywheel mass axis 15 is with a toothing provided, which serves as flywheel output gear 17.

Der Stirnradzug beginnend von dem linken Nachbarrad 9 besteht lediglich aus einer Zahnpaarung zwischen dem ersten Nachbarrad 9 und einem Schneidwalzen-Abtriebsrad 16. Das Schneidwalzen-Abtriebsrad 16 ist zentral auf der Schneidwalzenachse 13 angeordnet und nimmt das Antriebsmoment der Hydraulikmotore 6 für die Schneidwalze 11 entgegen. Die Übersetzung des Getriebes 2 zwischen dem Antrieb 3 und dem Abtrieb 4 der Schneidwalze 11 liegt im vorliegenden Beispiel geringfügig unter Eins. Die Motordrehzahl wird demnach in Richtung der Schneidwalze 11 herabgesetzt, das Drehmoment erhöht.The Stirnradzug starting from the left neighboring wheel 9 consists only of a tooth pairing between the first adjacent wheel 9 and a Cutting roller driven gear 16. The cutting roller driven gear 16 is central arranged on the cutting roller axis 13 and takes the drive torque of Hydraulic motors 6 for the cutting roller 11 against. The translation of the Getriebes 2 between the drive 3 and the output 4 of the cutting roller 11th is slightly less than one in this example. The engine speed is Accordingly, reduced in the direction of the cutting roller 11, the torque elevated.

Die Übersetzung des Getriebes 2 zwischen dem Antrieb 3 und dem Abtrieb 5 der Schwungmasse 12 ist dagegen deutlich größer als Eins, die Drehzahl der Schwungmasse 12 ist liegt somit deutlich über der Motor- und der Scheidwalzendrehzahl. Die Übersetzung zwischen dem Antrieb 3 und dem Abtrieb 5 der Schwungmasse 12 erfolgt über drei Stufen, indem das zweite Nachbarrad 10 mit einem Ritzel 18 auf einer Zwischenwelle 19 kämmt und wiederum das Rad 20 der Zwischenwelle 19 mit dem Schwungmassen-Abtriebsrad 17 in Eingriff steht.The translation of the transmission 2 between the drive 3 and the output 5 the flywheel 12, however, is significantly greater than one, the speed of Flywheel 12 is thus significantly above the engine and the Scheid roller speed. The translation between the drive 3 and the Downforce 5 of the flywheel 12 takes place via three stages, by the second Neighboring wheel 10 meshes with a pinion 18 on an intermediate shaft 19 and turn the wheel 20 of the intermediate shaft 19 with the flywheel output gear 17 is engaged.

Indem das Getriebe 2 die Winkelgeschwindigkeiten der Schneidwalze 11, der hydraulischen Motoren 6 und der Schwungmasse 12 zueinander in ein festes Verhältnis setzt, stellt es eine direkte Verbindung zwischen der Schneidwalze 11 und der Schwungmasse 12 her. Wird die rotierende Schneidwalze 11 durch einen Schlag von Außen belastet, wird dieser über den Antriebstrang entlang der Zahnräder 16, 9, 8, 10, 20, 17 in die Schwungmasse 12 weiter gegeben und von der dort gespeicherten kinetischen Energie absorbiert.By the transmission 2, the angular speeds of the cutting roller 11, the hydraulic motors 6 and the flywheel 12 to each other in a solid Ratio sets, it provides a direct connection between the cutting roller 11th and the flywheel 12 ago. If the rotating cutting roller 11 through a shock loaded from the outside, this is along the drive train along the gears 16, 9, 8, 10, 20, 17 further given in the flywheel 12 and absorbed by the kinetic energy stored there.
