Abstract
Description
Die Erfindung bezieht sich auf eine Bearbeitungseinrichtung zur Bearbeitung der Innenwand eines, insbesondere von der Kreisform abweichenden Profiles eines Erdbauwerkes, mit einem motorisch angetriebenen Werkzeug und Stützen zum Abstutzen der Einrichtung im Erdbauwerk.The invention relates to a processing device for processing the inner wall of a profile of an earth structure, in particular a profile that deviates from the circular shape, with a motor-driven tool and supports for supporting the device in the earth structure.
Bei Sanierungen von z.B. Kanälen wird häufig in der Weise vorgegangen, daß im Inneren des zu sanierenden Kanalprofiles entweder durch vorgefertigte Profilstücke, die selbsttragend im Inneren des alten Profiles aufgestellt werden, oder durch entsprechende verlorene Schalstücke praktisch im Inneren des alten Kanales ein neuer Kanal errichtet wird, wobei in letzterem Falle der Raum zwischen der verlorenen Schalung und der Innenwand des alten Kanalprofiles hinterfüllt wird.When renovating e.g. Channels are often proceeded in such a way that a new channel is built in the interior of the sewer profile to be renovated either by prefabricated profile pieces that are set up self-supporting in the interior of the old profile, or by appropriate lost formwork pieces in the interior of the old channel, the latter in the latter If the space between the lost formwork and the inner wall of the old sewer profile is backfilled.
Beispielsweise zeigt die DE-A-3 715 653 eine Vorrichtung zum Sanieren eines Kanalrohres, wobei ein über Laufstutzen an der Kanalrohrinnenwandung abgestützter Sanierwagen im Kanalrohr verfahren wird. Ein sich drehender Arbeitskopf, der eine selektiv in radialer Richtung bewegbare Testrolle umfaßt, dient der Auftragung von Sanierungsmaterial.For example, DE-A-3 715 653 shows a device for the renovation of a sewer pipe, wherein a renovation car supported on the inner wall of the sewer pipe is moved in the sewer pipe. A rotating working head, which comprises a test roller that can be moved selectively in the radial direction, is used to apply renovation material.
Anstelle einer verlorenen Schalung wird hier durch Auftragen einer Schicht über eine Auftragsdüse und Glätten desselben mittels einer Spachtel das Sanieren des Kanals durchgeführt.Instead of lost formwork, the canal is renovated by applying a layer over an application nozzle and smoothing it with a spatula.
Mit diesen Maßnahmen läßt sich zwar der Kanal relativ rasch und einfach sanieren, doch nimmt dessen Querschnitt entsprechend ab. Bei Kanälen mit sehr großen Querschnitten ist dies meist nicht besonders störend, da aufgrund der glatteren Wände das Schluckvermögen des Kanals kaum abnimmt. Bei kleineren Kanälen ergibt sich jedoch trotz glatteren Wänden und eines wesentlich geringeren Strömungswiderstands keine ausreichende Kompensation für den verminderten Querschnitt.With these measures, the canal can be renovated relatively quickly and easily, but its cross-section decreases accordingly. In the case of channels with very large cross sections, this is usually not particularly disruptive, since the swallowing capacity of the channel hardly decreases due to the smoother walls. With smaller channels, however, despite smoother walls and a significantly lower flow resistance, there is no adequate compensation for the reduced cross-section.
Um diese Querschnittsverminderung zu vermeiden, wird daher vorgeschlagen den Querschnitt des zu sanierenden Kanals vor dem Einbau des neuen Kanals zu vergrößern, z.B. durch Ausfräsen oder Ausschleifen des alten Querschnittes.In order to avoid this reduction in cross-section, it is therefore proposed to enlarge the cross-section of the sewer to be renovated before installing the new sewer, for example by milling or grinding the old cross-section.
Ziel der Erfindung ist es daher eine Bearbeitungseinrichtung der eingangs erwähnten Art vorzuschlagen, die ein einfaches, profilgenaues, erschütterungsarmes und rasches Vergrößern des lichten Querschnittes eines zu sanierenden Erdbauwerkes ermöglicht.The aim of the invention is therefore to propose a processing device of the type mentioned at the outset which enables a simple, precise, low-vibration and rapid enlargement of the clear cross section of an earthwork to be renovated.
Erfindungsgemäß wird hiezu vorgeschlagen, daß ein Gestell vorgesehen ist, das einen im wesentlichen in Längsrichtung des zu bearbeitenden Profiles verlaufenden Träger und mit diesem verbundene Spreizfüße zur Lagefixierung des Trägers im Erdbauwerk aufweist, an welchem Gestell ein Bearbeitungswerkzeug, z.B. eine Fräse, Schleifscheibe od. dgl., entsprechend dem Umriß des zu bearbeitenden Profils, vorzugsweise entlang einer Kulisse, bewegbar gehalten ist, wobei die Kulisse dem zu bearbeitenden Profil ähnlich ist und im wesentlichen senkrecht zur Längsachse des zu bearbeitenden Kanals steht.According to the invention it is proposed that a frame is provided which has a carrier running essentially in the longitudinal direction of the profile to be machined and spreading feet connected thereto for fixing the position of the carrier in the earthwork, on which frame a machining tool, for example a milling cutter, grinding wheel or the like ., according to the outline of the profile to be machined, preferably along a backdrop, is held movably, the backdrop being similar to the profile to be processed and being substantially perpendicular to the longitudinal axis of the channel to be processed.
Die Führung des Bearbeitungswerkzeuges entlang einer Kulisse führt zu einer relativ einfachen Konstruktion, erfordert allerdings für jedes zu bearbeitende Profil eine entsprechend gestaltete Kulisse. Es ist aber auch möglich das Bearbeitungswerkzeug an einem frei geführten Roboterarm zu halten, dessen Bewegungen mit einer entsprechenden Software profilkonform gesteuert werden kann. Auf diese Weise läßt sich die Bewegung des Bearbeitungswerkzeuges an jedes Profil auf einfache Weise anpassen.Guiding the machining tool along a backdrop leads to a relatively simple construction, but requires a correspondingly designed backdrop for each profile to be machined. However, it is also possible to hold the processing tool on a freely guided robot arm, the movements of which can be controlled with the appropriate software in accordance with the profile. In this way, the movement of the machining tool can be easily adapted to each profile.
Dabei ist es auch möglich eine der gewünschten Querschnittsform entsprechende Vergrößerung des Querschnittes des zu sanierenden Kanales vorzusehen.It is also possible to provide an enlargement of the cross-section of the duct to be renovated that corresponds to the desired cross-sectional shape.
In diesem Zusammenhang ist es vorteilhaft, wenn Spreizfüße an den beiden Enden des Gestells kreuz- bzw. sternförmig angeordnet sind. Hiedurch können die bei der Bearbeitung der Innenwand des Kanals auftretenden Kräfte optimal abgestützt werden. Außerdem wird durch diese Maßnahmen auch auf einfache Weise eine Einstellung des Gestelles in bezug auf die Längsachse des zu sanierenden Kanals ermöglicht.In this context, it is advantageous if spreading feet are arranged in a cross or star shape at the two ends of the frame. In this way, the forces occurring when machining the inner wall of the channel can be optimally supported. In addition, these measures also make it easy to adjust the frame with respect to the longitudinal axis of the sewer to be renovated.
Zur Schnittiefeneinstellung des Werkzeuges kann in Weiterbildung der Erfindung vorgesehen sein, daß das Werkzeug auf einem im wesentlichen parallel zum Träger verlaufenden und relativ zu diesem, vorzugsweise mittels eines Antriebes, verstellbaren Halterahmen angeordnet ist.In order to adjust the depth of cut of the tool, in a further development of the invention it can be provided that the tool is arranged on a holding frame which runs essentially parallel to the carrier and is adjustable relative thereto, preferably by means of a drive.
In Weiterbildung der Erfindung kann so vorgegangen werden, daß mit dem Halterahmen und/bzw. oder einer Halterung des Werkzeuges Antriebselemente, wie z.B. angetriebene Ketten-, Zahn- oder Reibräder, verbunden sind, die mit in den Kulissen gehaltenen Gegenelementen, wie z.B. Ketten, Zahnstangen oder Reibflächen, Zusammenwirken.In a further development of the invention can be done so that with the holding frame and / or. or a holder of the tool drive elements, such as driven chain, toothed or friction wheels, which are connected to counter elements held in the backdrop, e.g. Chains, racks or friction surfaces, interacting.
Insbesondere bei einem Antrieb mittels Kettenrädern und Ketten ergibt sich der Vorteil einer einfachen Ausbildung solcher Antriebe und der Vorteil einer weitgehenden Schlupffreiheit eines solchen Antriebes.In particular in the case of a drive by means of chain wheels and chains, there is the advantage of a simple design of such drives and the advantage of such a drive being largely free of slippage.
Mit einem solchen Antrieb kann ein sicherer und entlang der beiden Kulissen gleichmäßiger Vorschub des Werkzeuges sichergestellt werden.With such a drive, a safe and uniform feed of the tool can be ensured along the two scenes.
Weiters kann vorgesehen sein, daß der Halterahmen an den Kulissen in deren Umfangsrichtung, z.B. mittels dreier Rollen, einem Gleitschlitten od.dgl., verschiebbar geführt ist. Bei Verwendung von Rollen kann gegebenenfalls eine dieser Rollen in deren radialer Richtung federnd gehalten sein.Furthermore, it can be provided that the holding frame on the scenes in their circumferential direction, e.g. is slidably guided by means of three rollers, a sliding carriage or the like. When using rollers, one of these rollers can optionally be held in a springy manner in its radial direction.
Dadurch wird eine sichere Führung des Werkzeuges, bez. dessen Führung, entlang der Kulissen sichergestellt.This ensures safe guidance of the tool. its leadership, ensured along the scenes.
Eine solche Führung des Werkzeugs weist auch den Vorteil auf, daß sie mit verschiedenen Kulissen problemlos verwendet werden kann.Such a guide of the tool also has the advantage that it can be used with different scenes without any problems.
Um das Fortschreiten des Gestelles besonders einfach zu gestalten, kann weiters vorgesehen sein, daß der Träger mittels eines Antriebes an einem Schreitgestell verschiebbar gehalten ist, das im wesentlichen durch, vorzugsweise zwei, über einen Balken miteinander verbundene teleskopartig verstellbare Standfüße gebildet ist.In order to make the progress of the frame particularly simple, it can further be provided that the carrier is held displaceably by means of a drive on a walking frame, which is essentially formed by, preferably two, telescopically adjustable feet connected to one another via a beam.
Damit ist es möglich, mehrere der Breite des Werkzeuges, z.B. eines Fräskopfes, entsprechende, in Umfangsrichtung des Querschnittes des Kanals verlaufende Abschnitte desselben dadurch zu bearbeiten, daß der Träger auf dem Schreitgestell in Bearbeitungsrichtung vorgerückt wird. Damit kann eine entsprechende Verminderung der Rüstzeiten bei der Sanierung des Kanales erreicht werden. Hiedurch ist es ferner möglich, das Schreitgestell bei noch verspreiztem Gestell gegenüber diesem um etwa die Trägerlänge zu verstellen, wodurch eine einfache Vorschubmöglichkeit der Bearbeitungseinrichtung längs des zu sanierenden Erdbauwerkes geschaffen wird.This makes it possible to cover several of the width of the tool, e.g. a milling head to process corresponding sections of the same in the circumferential direction of the cross section of the channel in that the carrier is advanced on the walking frame in the machining direction. This enables a corresponding reduction in set-up times when renovating the sewer. In this way, it is also possible to adjust the walking frame with the frame still spread over it by about the carrier length, which creates a simple possibility of advancing the processing device along the earthwork to be renovated.
Um ein sicheres Verspreizen des Gestelles sicherzustellen, kann weiters vorgesehen sein, daß die Spreizfüße des Gestelles ausfahr- und verrastbare Stellfüße aufweisen.In order to ensure a secure spreading of the frame, it can further be provided that the spreading feet of the frame have adjustable feet that can be extended and locked.
Damit können die Spreizfüße auch an Stellen abgestützt werden, an denen sich Vertiefungen und Auskolkungen oder Ausbrüche befinden.This means that the spreading feet can also be supported in places where there are depressions and hollows or outbreaks.
Als besonders zweckmäßig hat es sich erwiesen, wenn die Spreizfüße des Gestelles ausfahr- und verrastbare Stellfüße aufweisen.It has proven to be particularly expedient if the spreading feet of the frame have adjustable feet that can be extended and locked.
Dies ermöglicht relativ kleine Antriebe, die relativ große Kräfte entwickeln können.This enables relatively small drives that can develop relatively large forces.

- FIG. 2 shows a side view of the device according to FIG. 1.
In dem zu sanierenden Kanal 1 ist ein Gestell 2, das im wesentlichen durch zwei Paare von kreuzweise angeordneten Spreizfüßen 3 und einem diese miteinander verbindenden Träger 4 gebildet ist, sodaß das Gestell 2 gegen die Innenwand des Erdbauwerkes verspreizbar ist. Naturgemäß ist die Erfindung auf vier kreuzförmige Spreizfüße nicht beschränkt, deren Zahl und Art der gegenseitigen Anordnung, z.B. sternförmig, wird im wesentlichen durch die besondere Form des Profilquerschnittes des zu bearbeitenden Erdbauwerkes bestimmt sein.In the channel 1 to be renovated there is a
An den kreuzweise angeordneten Spreizfüßen, die mittels Zylinder-Kolbenanordnungen 5 ausfahrbar sind, sind Kulissen 6 angeordnet, deren Umrißform dem Querschnitt des zu sanierenden Kanales 1 ähnlich ist und die senkrecht zu dem sich im wesentlichen in Richtung der Längsachse des zu sanierenden Kanals 1 erstreckenden Träger 4 angeordnet sind.On the crosswise arranged spreading feet, which can be extended by means of cylinder-
Auf diesen Kulissen 6 sind Ketten 7 angeordnet, mit denen Kettenräder 8 kämmen, die über weitere Kettenräder 9 und eine Kette 19 von einem Motor 10 angetrieben sind. Die Kettenräder 8 und der Motor 10 sind mit einem Halterahmen 11 verbunden bzw. von diesem gehalten. Anstelle des Kettenantriebes ist auch ein Zahnstangen- oder Reibradantrieb möglich. Weiters sind von diesem Halterahmen 11 noch drei weitere Rollen 18 gehalten, von denen eine in radialer Richtung federnd angeordnet sein kann. Diese Rollen gleiten längs der Kulissen 6, sodaß der Halterahmen 11 den Kulissen entlang bewegt werden kann. Anstelle der Rollen können auch ein Gleitschlitten od. dgl. zum Einsatz kommen.On these scenes 6
Der Halterahmen 11 ist zweiteilig ausgebildet. Auf dem Halterahmen 11a ist ein Bearbeitungswerkzeug, z.B. eine Fräse 12 oder ein Schleif- bzw. Hobelwerkezug, samt zugehörigem Antrieb 13 angeordnet, wobei auch eine Kühlwasserleitung 27 für das Werkzeug vorgesehen ist. Der Halterahmenteil 11b trägt die Rollen 18 und ist bei 25 am Halterahmenteil 11a verschiebbar gehalten. Durch ein Zylinder-Kolbenaggreagt 24 sind die Halterahmenteile 11a und 11b relativ zueinander verstellbar, wodurch die Einstellung der Schnittiefe des Bearbeitungswerkzeuges in einfacher Weise erreicht werden kann. Der mögliche Verstellweg kann durch einen Anschlag, z.B. durch eine Anschlagschraube 26, begrenzt werden.The holding frame 11 is formed in two parts. A processing tool, for example a milling cutter 12 or a grinding or planing tool, together with the associated drive 13 is arranged on the
Gleichfalls im Rahmen der Erfindung liegt eine konstruktive Ausgestaltung, bei welcher keine Kulissen vorgesehen sind und das Werkzeug 12 an einem frei geführten Roboterarm angeordnet ist, dessen sowohl Radial- als auch Längsbewegungen relativ zum Erdbauwerk von einer Software, insbesondere profilkonform gesteuert sind.Likewise within the scope of the invention is a constructive embodiment in which no scenes are provided and the tool 12 is arranged on a freely guided robot arm, the radial and longitudinal movements of which are controlled relative to the earth structure by software, in particular in accordance with the profile.
In dem Träger 4, der durch ein Hohlprofil gebildet ist, ist ein Schreitgestell 14 geführt, das im wesentlichen durch zwei miteinander über einen Balken 15 verbundene Standfüße 16 gebildet ist. Die Verstellung des Trägers 4 am Schreitgestell 14 erfolgt durch eine weitere Zylinder-Kolbenanordnung 20. Diese Standfüße 16 sind teleskopartig ausgebildet und jeweils mittels einer Zylinder-Kolbenanordnung 5 verstellbar.In the
Nach dem Verspreizen der Stützfüße 3 gegen die Wand des zu bearbeitenden Kanals 1 kann die Fräse 12 zunächst unter Abarbeitung des Kanals in Schneidrichtung 21 längs der Kulissen 6 bis zur Stirnseite 22 der Kanalsohle 23 bewegt werden, von wo sie wieder in ihre Ausgangslage entgegen der Schneidrichtung 21 zurücktransportiert wird. Sodann werden die Stützfüße 3 eingezogen und die Fräse um die Breite des Werkzeugs 12 unter Schnittiefenanpassung dadurch verstellt, daß der Träger 4 samt Halterahmen 11 längs des Balkens 15 des Schreitgestelles 14 verschoben wird. Nunmehr werden die Stützfüße 3 ausgefahren und neuerlich der Halterahmen 11 samt dem Werkzeug den Kulissen in Schneidrichtung 21 entlang geführt werden. Bei neuerlichem Erreichen von 22 erfolgt der Rücktransport, sodann die Versetzung des Werkzeuges usf., solange bis eine Endstellung des Gestells 2 in Bezug auf den Balken 15 erreicht ist.After the support feet 3 have been spread out against the wall of the channel 1 to be machined, the milling cutter 12 can first be moved in the cutting direction 21 along the scenes 6 up to the
Nunmehr kann bei arretiertem Gestell 2 und entarretiertem Schreitgestell 14 letzteres gegenüber dem Gestell 2 mittels der Zylinder-Kolbenanordnung 20 in Bearbeitungsrichtung des Kanals 1 verschoben werden, wonach die Stützfüße 16 des Schreitgestelles in Kontakt mit dem Boden des Kanals gebracht werden können, sodaß das Schreitgestell aufsteht. Anschließend kann die Abarbeitung des Erdbauwerkes in der weiter oben erläuterten Weise fortgesetzt werden.Now, with the
