Abstract

A self-propelled aggregate crusher has a chassis (8) supported on a crawler drive comprising two tracked drives. The chassis supports an input hopper (9) which feeds the aggregate between pairs of crusher plates (10) in a vertical configuration and driven by a drive unit (11). The crushed aggregate drops onto the bottom end of a conveyor (12) which lifts the crushed material to a discharge point. The whole chassis can be lifted to tilt about a tilt axis (15) parallel to the wheel axes and near to one end of the tracked drives. This provides access to the crusher mechanism and the drives and transporter i.e. to areas which suffer heavy wear.

Description

Die Erfindung bezieht sich auf eine fahrbare Brecheinrichtung mit einem Raupenfahrwerk, einem vom Raupenfahrwerk getragenen Chassis, in dem ein motorbetriebenes Brechwerkzeug, beispielsweise in Form von paarweise angeordneten, gegeneinander schwingenden Brechplatten in im wesentlichen aufrechter Anordnung und mindestens ein Antriebsaggregat für das Brechwerkzeug vorgesehen sind und an dem ein Einfüllschacht festgelegt ist, und mit einem das gebrochene Material austragenden Förderband, das am Chassis angeordnet ist und das mit seinem materialaufnehmenden Ende unter das Chassis ragt, und Einfüllschacht und Förderband, bezogen auf das Raupenfahrwerk, an einander gegenüberliegenden Seiten angeordnet sind.The invention relates to a mobile crushing device with a crawler track, a chassis supported by the crawler chassis, in which a motor-driven Breaking tool, for example in the form of pairs, oppositely vibrating crushing plates in substantially upright Arrangement and at least one drive unit provided for the breaking tool are and on which a feed chute is fixed, and with the broken one Material discharge conveyor belt which is arranged on the chassis and that protrudes under the chassis with its material-absorbing end, and filler shaft and conveyor belt, based on the crawler track, on opposite one another Pages are arranged.

Einrichtungen dieser Art sind in verschiedenen Ausführungsformen bekannt (EP 0 547 440 B1; DE-OS 39 04 501 A1; DE-A-32 27 834; DE-U-85 34 877.5; DE-A-36 37 389).Devices of this type are known in various embodiments (EP 0 547 440 B1; DE-OS 39 04 501 A1; DE-A-32 27 834; DE-U-85 34 877.5; DE-A-36 37 389).

Die Brechwerkzeuge bei solchen Brecheinrichtungen und die darunter befindlichen Maschinenteile, insbesondere das Förderband, sind hoch beanspruchte Maschinenteile, die einer eingehenden Wartung bedürfen und die einem hohen Verschleiß unterworfen sind. Bei all diesen bekannten Brecheinrichtungen sind diese hoch beanspruchten Maschinenteile jedoch nur sehr schwer zugänglich. Bei der Brecheinrichtung nach der EP 0 547 440 B1 ist der Einfüllschacht zwar gegenüber dem Chassisrahmen verschwenkbar gelagert, doch dient diese Maßnahme dafür, die Brecheinrichtung mit einem Sattelschlepper auf öffentlichen Verkehrsflächen transportieren zu können. Auch bei der Brecheinrichtung nach DE-OS 39 04 501 A1 kann der Einfüllschacht gegenüber dem Chassisrahmen abgesenkt werden. Auch diese Maßnahme dient dazu, die Höhe der Brecheinrichtung für den Straßentransport derselben zu verringern, ohne daß dadurch die Brechwerkzeuge bzw. die darunter befindlichen Maschinenteile leichter zugänglich würden.The crushing tools in such crushers and those below Machine parts, especially the conveyor belt, are highly stressed Machine parts that require thorough maintenance and high ones Are subject to wear. All of these known crushing devices are however, these highly stressed machine parts are very difficult to access. In the crushing device according to EP 0 547 440 B1, the feed chute is indeed pivoted relative to the chassis frame, but this measure serves for it, the crushing device with a semitrailer on public To be able to transport traffic areas. Even with the crushing device after DE-OS 39 04 501 A1 can the filling shaft opposite the chassis frame be lowered. This measure also serves the height of the crushing device to reduce the same for road transport without the Breaking tools and the machine parts underneath are more easily accessible would.

Von diesem Stand der Technik geht die Erfindung aus, und sie zielt darauf ab, eine Einrichtung der eingangs genannten Art so konstruktiv zu gestalten, daß im Bedarfsfalle für Wartungs- und Instandhaltungszwecke die hoch beanspruchten Maschinenteile leicht zugänglich werden. Die Erfindung löst diese Aufgabe dadurch, daß das Chassis als Ganzes und mit den von ihm getragenen und aufgenommenen Aggregaten um eine horizontale, parallel zu den Achsen der Räder des Raupenfahrwerkes liegende Schwenkachse verschwenkbar ist. Dank dieser Maßnahme kann das Chassis mit allen von ihm getragenen Aggregaten gegenüber dem Raupenfahrwerk angehoben werden, so daß die hoch beanspruchten und einem erheblichen Verschleiß unterworfenen Maschinenteile direkt von unten für das Montage- und Servicepersonal zugänglich werden. Diese erwähnten Montage- und Wartungsarbeiten können daher gegenüber früher unter erheblicher Zeiteinsparung abgewickelt werden, wodurch sich die Wartungs- und Instandhaltungskosten nicht unerheblich reduzieren.The invention is based on this state of the art and aims at to design a device of the type mentioned so constructively that in Trap for maintenance and repair purposes the highly stressed Machine parts become easily accessible. The invention solves this problem by that the chassis as a whole and with the ones it supports and supports Aggregates around a horizontal, parallel to the axes of the wheels of the crawler track lying pivot axis is pivotable. thanks to this The chassis can measure against all the aggregates it supports the crawler chassis are raised so that the highly stressed and machine parts subject to considerable wear directly from below become accessible to assembly and service personnel. This mentioned assembly and maintenance work can therefore be considerably more than in the past Time savings are processed, which increases the maintenance and repair costs not insignificantly reduce.

Nach einem weiteren Merkmal der Erfindung ist vorgesehen, daß die Schwenkachse innerhalb des zwei Rahmen aufweisenden Raupenfahrwerkes liegt, um die hier vorgesehene Konstruktion möglichst einfach ausführen zu können, und zwar unter Beiziehung von Bauelementen, die eine Brecheinrichtung bereits aufweist.According to a further feature of the invention it is provided that the pivot axis is within the two-frame crawler chassis to the to be able to carry out the construction provided here as simply as possible, namely involving components that a crushing device already has.

Ist dabei die Schwenkachse durch einen die beiden Rahmen des Raupenfahrwerkes verbindenden Holm gebildet, so kann dieses beim Raupenfahrwerk bereits vorhandene Bauelement in zweckmäßiger Weise in die neue Konstruktion integriert werden.Is the swivel axis through one of the two frames of the crawler track connecting spar formed, this can already with the crawler chassis existing component in a convenient manner in the new construction to get integrated.

Damit für den Transport der Brecheinrichtung auf einem dafür geeigneten Fahrzeug die beim betriebsmäßigen Einsatz der Brecheinrichtung hochliegende obere Kante des Einfüllschachtes relativ weit absenkbar ist, liegt die Schwenkachse nahe einem Umlenk- oder Antriebsrad des Raupenfahrwerkes. Dabei liegt die Schwenkachse bevorzugt zwischen den Umlenk- oder Antriebsrädern des Raupenfahrwerkes.So for the transport of the crushing device on a suitable vehicle the upper one lying high during operational use of the crushing device The swivel axis lies on the edge of the filler shaft near a deflection or drive wheel of the crawler track. Here lies the Swivel axis preferably between the deflection or drive wheels of the crawler track.

Bei einer praktischen Ausführungsform der Brecheinrichtung ist unmittelbar unterhalb des Einfüllschachtes ein fest angeordnetes, waagrecht liegendes Förderband angeordnet, das der Vorsortierung des Materials dient und dessen Abgabeseite oberhalb der Aufnahmeseite des schräg angeordneten, austragenden Förderbandes liegt. Die der Querversteifung des den Einfüllschacht tragenden Chassis dienenden Mittel sind daher unterhalb des ersterwähnten Förderbandes anzuordnen. Es ist daher vorgesehen, daß das Chassis unterhalb des Einfüllschachtes und gegebenenfalls des Antriebsaggregates nach unten hin durch eine im wesentlichen gerade verlaufende Kontur begrenzt ist, welche auf der dem Einfüllschacht abgewandten Seite zur Bildung von Lagerschalen nach unten gezogen ist und die gerade verlaufende Kontur in der Betriebsstellung der Brecheinrichtung im wesentlichen horizontal verläuft, um auf diese Weise für die erwähnten Mittel hinreichend Platz zu schaffen.In a practical embodiment of the crushing device is immediately below the feed chute a fixed, horizontal conveyor belt arranged, which serves the pre-sorting of the material and its delivery side above the receiving side of the obliquely arranged, discharge conveyor belt lies. The cross bracing of the chassis supporting the filler shaft serving means are therefore to be arranged below the first-mentioned conveyor belt. It is therefore envisaged that the chassis will be below the filler shaft and possibly the drive unit downwards by an in essentially straight contour is limited, which on that of the feed chute opposite side pulled down to form bearing shells and the straight contour in the operating position of the crushing device runs essentially horizontally in this way for those mentioned Means to create sufficient space.

Andererseits ist für die Zugänglichkeit der zu wartenden Baukomponenten hinreichend Platz vorzusehen und ein ausreichender Freiraum dafür zu schaffen. Dies wird dadurch erreicht, daß in der Betriebsstellung des Chassis die untere, gerade verlaufende Kontur desselben oberhalb des Raupenfahrwerkes liegt.On the other hand, the accessibility of the components to be serviced is sufficient Provide space and create sufficient space for it. This is achieved in that the lower, straight in the operating position of the chassis running contour of the same lies above the crawler track.

Ist nach einem weiteren Merkmal der Erfindung vorgesehen, daß am Raupenfahrwerk auf der der Schwenkachse des Chassis abgewandten Seite mindestens eine Kolben-Zylinder-Einheit angeordnet ist, deren eine Ende am Chassisrahmen festgelegt ist, so dient dies ebenfalls zur Vereinfachung der Konstruktion. Am Raupenfahrwerk ist in dem hier angesprochenen Bereich eine die beiden Raupenfahrwerke verbindende Querversteifung vorgesehen. An dieser Querversteifung, die für die Raupenfahrwerke erforderlich ist, kann dabei die Kolben-Zylinder-Einheit angelenkt werden.Is provided according to a further feature of the invention that on the crawler track at least on the side facing away from the pivot axis of the chassis a piston-cylinder unit is arranged, one end of which on the chassis frame is fixed, this also serves to simplify the construction. At the Crawler undercarriage is one of the two crawler undercarriages in the area mentioned here connecting cross stiffener provided. At this cross bracing, The piston-cylinder unit can be used for the crawler tracks be articulated.

Liegt der Anlenkpunkt der Kolben-Zylinder-Einheit am Chassis seitlich des Raupenfahrwerkes - bezogen auf dessen Längsachse - so dient dies ebenfalls zur Vereinfachung der Konstruktion. In dem erwähnten Bereich des Chassis ist dessen Querversteifung vorgesehen, an welcher die Kolben-Zylinder-Einheit mit ihrem einen Ende anlenkbar ist.The pivot point of the piston-cylinder unit is on the chassis to the side of the crawler track - Based on its longitudinal axis - this also serves for Simplification of construction. In the mentioned area of the chassis is its Cross stiffening provided on which the piston-cylinder unit with its one end is articulated.

Brecheinrichtungen der gegenständlichen Art haben erhebliche Abmessungen und ein außerordentliches Gewicht. In der Regel ist eine solche Brecheinrichtung über 11 m lang und besitzt ein Gewicht von 28 t. Um für ein derartiges Gerät eine ausreichende Beweglichkeit und Manövrierbarkeit zu erzielen, ist vorgesehen, daß das Chassis das Raupenfahrwerk beidseitig überragt.Crushing devices of the type in question have considerable dimensions and an extraordinary weight. As a rule, such a breaking device over 11 m long and has a weight of 28 t. In order for such a device It is intended to achieve sufficient mobility and maneuverability that the chassis projects beyond the crawler tracks on both sides.

Wird die Brecheinrichtung auf einem dafür geeigneten Fahrzeug auf öffentlichen Verkehrswegen transportiert, so darf eine vorgegebene Höhe nicht überschritten werden. Um eine aufwendige Konstruktion zu vermeiden, mit deren Hilfe das geneigt angeordnete, austragende Förderband für Transporzwecke evtl. verkürzbar ist, ist vorgesehen, daß das Abwurfende des Förderbandes in der Betriebsstellung des Chassis unterhalb einer gedachten Horizontalebene liegt, die die Oberkante des Einfüllschachtes beinhaltet.If the crushing device is on a suitable vehicle on public Transport routes, a predetermined height may not exceed become. To avoid a complex construction, with the help of which inclined arranged, discharge conveyor belt for transport purposes may be shortenable is provided that the discharge end of the conveyor belt in the operating position of the chassis is below an imaginary horizontal plane, which is the top edge of the filler shaft.

Um zum Verschwenken des Chassis eine Kolben-Zylinder-Einheit mit großem Hub einsetzen zu können, liegt der Anlenkpunkt der Kolben-Zylinder-Einheit am Raupenfahrwerk unterhalb einer Horizontalebene, die die Achsen der Umlenk- oder Antriebsräder des Raupenfahrwerkes enthält. Trotz der sehr beengten Platzverhältnisse im erwähnten Bereich kann dadurch ein verhältnismäßig großer Schwenkwinkel erzielt werden.To swivel the chassis, a piston-cylinder unit with a large To be able to use the stroke, the articulation point of the piston-cylinder unit is on Crawler under a horizontal plane that the axes of the deflection or Contains drive wheels of the crawler chassis. Despite the very limited space in the area mentioned, this can result in a relatively large one Swivel angle can be achieved.

Ist weiter vorgesehen, daß die Schwenkachse des Chassis seitlich der Brechwerkzeuge liegt, so sind im Bedarfsfalle die zu wartenden Teile der Brecheinrichtung leicht zugänglich.It is also provided that the pivot axis of the chassis laterally of the crushing tools is, if necessary, the parts of the crushing device to be serviced easily accessible.

Ist das Chassis, bezogen auf seine Betriebsstellung, sowohl nach oben wie auch nach unten verschwenkbar, so werden dadurch nicht nur Instandhaltungs-, Wartungs- und Reparaturarbeiten erleichtert, es ist auch möglich, für den Straßentransport der Brecheinrichtung deren Höhe etwas zu reduzieren, so daß die für solche Transporte zulässige Höhe von 400 cm nicht überschritten wird, widrigenfalls der Transport der Einrichtung auf öffentlichen Verkehrswegen nicht nur mit kostspieligen Sondergenehmigungen verbunden wäre, sondern auch mit Einschränkungen, was die Transportwege betrifft.Is the chassis, based on its operating position, both upwards as well Swiveling downwards, this not only makes maintenance, servicing and repair work easier, it is also possible for road transport the crushing device to reduce its height somewhat, so that for such transports permissible height of 400 cm is not exceeded, otherwise the transportation of the facility on public roads not only with expensive special permits, but also with restrictions, as far as the transport routes are concerned.

    • Die Brecheinrichtung weist ein Raupenfahrwerk 1 auf, das zwei voneinander distanzierte Rahmen besitzt, welche - bezogen auf die Darstellung nach den Fig. 1 bis 3 - rechtwinkelig zur Zeichenebene gesehen hintereinander liegen. Diese beiden Rahmen 2 sind durch Querholme 3 und 4 miteinander verbunden. An den Stirnseiten der beiden Rahmen 2 sind jeweils Umlenk- oder Antriebsräder 5 und 6 vorgesehen, über welche die Raupenkette 7 geführt ist.The breaking device has a crawler track 1 which has two spaced apart Has frame, which - based on the representation of FIG. 1st to 3 - seen one behind the other at right angles to the drawing plane. This both frames 2 are connected to each other by cross bars 3 and 4. To the End faces of the two frames 2 are deflection or drive wheels 5 and 6, respectively provided, over which the crawler belt 7 is guided.

    Dieses Raupenfahrwerk 1 trägt ein Chassis 8 mit einem Einfüllschacht 9, mit Brechplatten 10 und einem Antriebsaggregat 11 für den Betrieb der Brechplatten 10, des weiteren ist ein Förderband 12 vorgesehen, das ebenfalls mit dem Chassis 8 verbunden ist und dessen materialaufnehmendes Ende bis unter das Chassis 8, vorzugsweise bis unter die Brechplatten 10 ragt. Die Brechplatten 10 sind im wesentlichen aufrecht angeordnet.This crawler chassis 1 carries a chassis 8 with a feed chute 9 Crushing plates 10 and a drive unit 11 for the operation of the crushing plates 10, a conveyor belt 12 is also provided, which is also connected to the chassis 8 is connected and its material-receiving end to below the chassis 8, preferably protrudes below the crushing plates 10. The crushing plates 10 are arranged essentially upright.

    Unterhalb des Einfüllschachtes 9 und auch zum Teil unterhalb des Antriebsaggregates 11 ist das Chassis 8 nach unten hin durch eine im wesentlichen gerade verlaufende Kontur 13 begrenzt, welche auf der dem Einfüllschacht abgewandten Seite zur Bildung von Lagerlaschen nach unten gezogen ist und dabei eine Art Lasche 14 bildet. In der Betriebsstellung der Brecheinrichtung liegt diese gerade verlaufende Kontur 13 im wesentlichen horizontal (Fig. 1) und oberhalb des Raupenfahrwerkes 1.Below the filling shaft 9 and also partially below the drive unit 11, the chassis 8 is downward through a substantially straight running contour 13 limited, which on the side facing away from the filler shaft Side to form bearing brackets is pulled down and a kind Tab 14 forms. In the operating position of the crushing device, it is straight running contour 13 substantially horizontally (Fig. 1) and above the crawler track 1.

    Die nach unten gezogene Lasche 14 des Chassis 8 ist am Holm 4 des Raupenfahrwerkes 1 festgelegt, und zwar in der Weise, daß das Chassis 8 als Ganzes mit allen von ihm getragenen Aggregaten um die Achse dieses Holmes 4 schwenkbar ist, so daß dieser Holm 4 eine Schwenkachse 15 bildet. Diese Schwenkachse 15 liegt somit innerhalb des die beiden Rahmen 2 aufweisenden Raupenfahrwerkes 1. Der Holm 4 bzw. die durch ihn gebildete oder definierte Schwenkachse 15 liegt dabei nahe dem einen Umlenk- oder Antriebsrad 6.The downward tab 14 of the chassis 8 is on the spar 4 of the crawler track 1 set, in such a way that the chassis 8 as a whole with all the aggregates he carries around the axis of this spar 4 is pivotable so that this spar 4 forms a pivot axis 15. This Pivot axis 15 is thus within the two frame 2 Crawler undercarriage 1. The spar 4 or the one formed or defined by it The pivot axis 15 is close to the one deflection or drive wheel 6.

    Auf der der Schwenkachse 15 bzw. dem einen Holm 4 abgewandten Seite des Chassis 8 ist eine Kolben-Zylinder-Einheit 16 vorgesehen, die zwischen den beiden Rahmen 2 des Raupenfahrwerkes 1 liegt und deren eine Ende 17 am Chassis 8 festgelegt ist. Der Anlenkpunkt der Kolben-Zylinder-Einheit 16 am Chassis 8 liegt seitlich des Raupenfahrwerkes 1 - bezogen auf dessen Lenkachse. Das Chassis 8 überragt das Raupenfahrwerk 1 beidseitig.On the pivot axis 15 or the one spar 4 side of the Chassis 8 is a piston-cylinder unit 16 provided between the two Frame 2 of the crawler chassis 1 is located and one end 17 on the chassis 8 is set. The articulation point of the piston-cylinder unit 16 on the chassis 8 is on the side of the crawler chassis 1 - based on its steering axis. The Chassis 8 projects beyond the crawler chassis 1 on both sides.

    Das Abwurfende 18 des Förderbandes 12 liegt in der Betriebsstellung des Chassis 8 (Fig. 1) unterhalb einer gedachten Horizontalebene, die die Oberkante 19 des Einfüllschachtes 9 beinhaltet.The discharge end 18 of the conveyor belt 12 is in the operating position of the chassis 8 (FIG. 1) below an imaginary horizontal plane, which is the upper edge 19 of the feed chute 9 includes.

Dies ist gleichzeitig die größte Höhe der Brecheinrichtung. Sind an den hoch beanspruchten, unten liegenden Maschinenteilen Wartungs- und Servicearbeiten durchzuführen, so wird die Kolben-Zylinder-Einheit 16 beaufschlagt, wodurch das Chassis als Ganzes mit all seinen Aggregaten um seine Schwenkachse 15 im Uhrzeigersinn (Fig. 2) verschwenkt wird. Dadurch wird die Unterseite des Chassis frei, und die hier liegenden Maschinenteile werden für das Wartungspersonal zugänglich, ohne daß große Demontagearbeiten verrichtet werden müssen.1 shows the operating position of the chassis 8. The height H of the crushing device, based on the upper edge 19 of the feed chute 9, is approximately 350 cm. This is also the greatest height of the crushing device. Are at the highly stressed machine parts underneath maintenance and service work perform, so the piston-cylinder unit 16 is acted on, whereby the Chassis as a whole with all its units around its pivot axis 15 in Clockwise (Fig. 2) is pivoted. This will underside the chassis free, and the machine parts lying here are accessible to the maintenance personnel, without major disassembly work.

    Dank der erfindungsgemäßen Maßnahme wird aber noch ein weiterer Vorteil erzielt: Für den Transport auf der Straße wird die Brecheinrichtung als Ganzes auf einen Tieflader 20 gestellt, dessen Ladefläche ca. 86 cm über Niveau liegt. Für diesen Transport wird nun die Kolben-Zylinder-Einheit 16 entlüftet, und dadurch kann das Chassis 8 nach unten abgesenkt werden (Fig. 3), so daß die gesamte Höhe (Tieflader plus Brecheinrichtung) die für einen solchen Transport zulässige Höhe von 400 cm nicht überschreitet. In dieser abgesenkten Stellung des Chassis 8 (Fig. 2) liegt kein Punkt der Brecheinrichtung höher, als es dem erwähnten zulässigen Maß entspricht.Thanks to the measure according to the invention, yet another advantage is achieved: The crusher is opened as a whole for transport by road placed a low loader 20, the loading area is about 86 cm above level. For this transport, the piston-cylinder unit 16 is now vented, and thereby the chassis 8 can be lowered (Fig. 3) so that the entire Height (low loader plus crushing device) the permissible for such a transport Height of 400 cm. In this lowered position of the chassis 8 (Fig. 2) is no point of the crushing device higher than that mentioned permissible dimension corresponds.

    Die Aufbauten am Chassis 8 und die von ihm getragenen Aggregate wurden vorstehend nicht im einzelnen erörtert, dies deswegen, da sie die Erfindung als solche nicht unmittelbar betreffen. Wesentlich für die Erfindung ist die schwenkbare Lagerung des Chassis 8 als Ganzes mit all seinen Aggregaten um eine Schwenkachse 15, die seitlich der Brechwerkzeuge liegt, so daß die unten liegenden Maschinenteille für das Wartungspersonal zugänglich werden.The structures on the chassis 8 and the units carried by it were protruding not discussed in detail because it is the invention as such not directly affect. The pivotable is essential for the invention Storage of the chassis 8 as a whole with all of its units around a swivel axis 15, which is to the side of the crushing tools, so that the machine parts below become accessible to maintenance personnel.

    Aus den vorstehenden Darlegungen und den Zeichnungen ist ersichtlich, daß das Chassis 8 gegenüber seiner normalen Betriebsstellung, die in Fig. 1 gezeigt ist, sowohl nach oben für Wartungszwecke und Reparatureinsätze sowie nach unten für den Transport verschwenkt werden kann. From the above statements and the drawings it can be seen that the Chassis 8 in relation to its normal operating position, which is shown in FIG. 1, both upwards for maintenance purposes and repairs as well as downwards can be pivoted for transport.
