Description

Die Erfindung betrifft einen Gleitschalungsfertiger mit einem in der Höhe verstellbaren Maschinenrahmen und einer am Maschinenrahmen angeordneten Montageeinheit zur Befestigung einer Betonmulde. Darüber hinaus betrifft die Erfindung einen Gleitschalungsfertiger mit einer Betonmulde.The invention relates to a slipform paver with a height-adjustable machine frame and an assembly unit arranged on the machine frame for fastening a concrete trough. In addition, the invention relates to a slipform paver with a concrete trough.

Mit den bekannten Gleitschalungsfertigern können Bauteile aus einem fließfähigen Material, insbesondere Beton, kontinuierlich hergestellt werden. Die Gleitschalungsfertiger verfügen über eine Vorrichtung, in der das fließfähige Material in die gewünschte Form gebracht wird. Eine derartige Vorrichtung zum Formen des fließfähigen Materials wird auch als Betonmulde bezeichnet. Zur Herstellung von Bauteilen mit unterschiedlichem Querschnitt müssen die Betonmulden ausgewechselt werden. Daher verfügen die bekannten Gleitschalungsfertiger über eine Montageeinheit, an der Betonmulden unterschiedlicher Ausbildung befestigt werden können.With the known slipform pavers, components made of a flowable material, in particular concrete, can be manufactured continuously. The slipform pavers have a device in which the flowable material is brought into the desired shape. Such a device for shaping the flowable material is also referred to as a concrete trough. To produce components with different cross sections, the concrete troughs must be replaced. Therefore, the known slipform pavers have an assembly unit to which concrete troughs of different designs can be attached.

Der Maschinenrahmen der bekannten Gleitschalungsfertiger ist über Hubsäulen mit Kettenlaufwerken verbunden. Durch Ein- bzw. Ausfahren der Hubsäulen kann der Maschinenrahmen in der Höhe verstellt werden. Dabei kann der Maschinenrahmen an der in Arbeitsrichtung linken oder rechten Seite angehoben bzw. abgesenkt und/oder an der in Arbeitsrichtung vorderen und hinteren Seite angehoben bzw. abgesenkt werden. Da die Betonmulde fest mit dem Maschinenrahmen verbunden ist, bestimmt die Ausrichtung des Maschinenrahmens auch die Ausrichtung der Betonmulde.The machine frame of the known slipform pavers is connected to chain drives via lifting columns. The height of the machine frame can be adjusted by retracting or extending the lifting columns. The machine frame can be raised or lowered on the left or right side in the working direction and / or raised or lowered on the front and rear side in the working direction. Since the concrete trough is firmly connected to the machine frame, the orientation of the machine frame also determines the orientation of the concrete trough.

Die US-A-6 109 825 beschreibt einen Gleitschalungsfertiger mit einer Betonmulde, dessen Maschinenrahmen an Hubsäulen in der Höhe verstellbar ist.The US-A-6 109 825 describes a slipform paver with a concrete trough, the machine frame of which can be adjusted in height on lifting columns.

Die EP 1 264 943 A2 beschreibt einen Gleitschalungsfertiger, der einen in der Höhe verstellbaren Maschinenrahmen und eine Antriebseinheit mit Antriebsmitteln zur Ausführung von translatorischen und/oder rotatorischen Bewegungen aufweist. Der Gleitschalungsfertiger verfügt über verschiedene Arbeitseinheiten. Diese Arbeitseinheiten umfassen jeweils Bauteile, die an den Seitenteilen des Maschinenrahmens unbeweglich oder schwenkbar befestigt sind. Die Bauteile einer Arbeitseinheit bilden das Oberteil einer Form für Beton. Bei der Ausfuhrungsform, bei der die Bauteile schwenkbar an dem Maschinenrahmen befestigt sind, kann das Profil des zu fertigenden Betonteils verändert werden. Für die Herstellung eines Betonteils mit einem schrägen Dachprofil werden die beiden Bauteile schräggestellt. Die Betonform wird von verschiedenen Teilen gebildet, die mit dem Maschinenrahmen verbunden sind.The EP 1 264 943 A2 describes a slipform paver which has a height-adjustable machine frame and a drive unit with drive means for executing translatory and / or rotary movements. The slipform paver has different working units. These work units each comprise components which are fixed immovably or pivotably on the side parts of the machine frame. The components of a work unit form the upper part of a mold for concrete. In the embodiment in which the components are pivotally attached to the machine frame, the profile of the concrete part to be manufactured can be changed. For the production of a concrete part with an inclined roof profile, the two components are inclined. The concrete form is made up of various parts that are connected to the machine frame.

Aus der DE 27 39 452 A1 ist eine Baumaschine zum Auskleiden eines Grabens bekannt, die über einen seitlichen Rahmen verfügt, der schwenkbar an dem Maschinenrahmen der Baumaschine befestigt ist. Der seitliche Rahmen umfasst eine Betonform zur Herstellung einer Auskleidung eines Grabens. Der Rahmen besteht aus einer Anzahl starrer rohrförmiger Elemente, die in einer im Wesentlichen rechtwinkligen Konfiguration zusammengeschweißt sind. Die schwenkbare Befestigung des seitlichen Rahmens an dem Maschinenrahmen dient allein der Ausrichtung des Rahmens in Bezug auf die Neigung des Grabens (Hang).From the DE 27 39 452 A1 a construction machine for lining a trench is known, which has a side frame which is pivotally attached to the machine frame of the construction machine. The side frame comprises a concrete mold for producing a trench lining. The frame consists of a number of rigid tubular members welded together in a substantially rectangular configuration. The pivotable attachment of the side frame to the machine frame only serves to align the frame with respect to the inclination of the trench (slope).

Eine Baumaschine zum Auskleiden eines Grabens, die einen an dem Maschinenrahmen der Baumaschine schwenkbar befestigten seitlichen Rahmen aufweist, ist auch aus der GB 1 513 615 A bekannt.A construction machine for lining a trench, which has a side frame pivotably attached to the machine frame of the construction machine, is also from the GB 1 513 615 A. known.

Die US 3 625 121 A beschreibt eine Vorrichtung zur Herstellung von Schichten aus Bitumen. Die Vorrichtung verfügt über eine profilierte Führungsplatte und eine Schleppplatte, die der Herstellung einer Schicht aus Bitumen dienen. Die Führungsplatte ist schwenkbar an einer weiteren Platte festigt. Zum Einstellen oder Justieren der Winkelstellung der Führungsplatte ist ein Mechanismus vorgesehen.
Die bekannten Gleitschalungsfertiger erlauben die Herstellung von Bauteilen mit einer sich über deren Länge kontinuierlich verändernden Ausrichtung. Dabei ändert sich auch die Kontur bzw. der Querschnitt der Bauteile kontinuierlich über die Länge, wenn man voraussetzt, dass der Boden, auf den das Bauteil errichtet werden soll, eben ist. Mit den bekannten Gleitschalungsfertigern lassen sich beispielsweise Wasserrinnen herstellen, die unter anderem eine dem Verkehrsweg zugewandte innere Flanke aufweisen und deren Neigung sich entlang des Verkehrsweges kontinuierlich ändert. Im Bereich der Abläufe liegt die innere Flanke in der Ebene des Verkehrsweges, während die Flanke zwischen den Abläufen gegenüber dem Verkehrsweg nach innen geneigt ist. Auf der halben Strecke zwischen den Abläufen kann die Flanke die größte Neigung haben.The US 3,625,121 A describes an apparatus for producing layers of bitumen. The device has a profiled guide plate and a drag plate, which are used to produce a layer of bitumen. The guide plate is pivotally attached to another plate. A mechanism is provided for adjusting or adjusting the angular position of the guide plate.
The known slipform pavers allow the production of components with an orientation that changes continuously along their length. The contour or cross-section of the components also changes continuously over the length if one assumes that the floor on which the component is to be built is level. With the known slipform pavers, for example, water channels can be produced which, among other things, have an inner flank facing the traffic route and the inclination of which continuously changes along the traffic route. In the area of the processes, the inner flank lies in the level of the traffic route, while the flank between the processes is inclined inwards with respect to the traffic route. The flank can have the greatest slope halfway between the processes.

Zur Fertigung von Wasserrinnen mit einer sich kontinuierlich verändernden Ausrichtung ist es erforderlich, die Ausrichtung des Maschinenrahmens während des Vorschubs des Gleitschalungsfertigers kontinuierlich zu verändern. Während sich der Gleitschalungsfertiger entlang einer Referenz, beispielsweise entlang eines Leitdrahtes bewegt, werden die in Arbeitsrichtung rechten bzw. linken Hubsäulen fortlaufend ein- bzw. ausgefahren, um die Betonmulde in die gewünschte Position zu kippen. Nachteilig ist, dass schon geringe Neigungen der Betonmulde aufgrund des relativ großen Abstandes zu den Hubsäulen zu verhältnismäßig großen Kippbewegungen des Maschinenrahmens führen. Das fortlaufende Kippen des Maschinenrahmens während des Arbeitseinsatzes erschwert nicht nur die Arbeitsbedingungen des Maschinenführers, sondern führt auch zu einem unnötigen Verschleiß der die relativ großen Hubbewegungen ausführenden Hubsäulen. Des Weiteren führen die Kippbewegungen des Maschinenrahmens zu einer unerwünschten Schrägstellung des Förderbandes der Fördereinrichtung des Gleitschalungsfertigers zum Beschicken der Betonmulde mit Beton.In order to produce water channels with a continuously changing orientation, it is necessary to continuously change the orientation of the machine frame during the advance of the slipform paver. While the slipform paver moves along a reference, for example along a guide wire, the right and left lifting columns in the working direction are continuously extended or retracted in order to tilt the concrete trough into the desired position. The disadvantage is that even slight inclinations of the concrete trough lead to relatively large tilting movements of the machine frame due to the relatively large distance from the lifting columns. The continuous tilting of the machine frame during use not only complicates the operating conditions of the machine operator, but also leads to unnecessary wear and tear on the lifting columns which carry out the relatively large lifting movements. Furthermore, the tilting movements of the machine frame lead to an undesired inclination of the conveyor belt of the conveyor device of the slipform paver for loading the concrete trough with concrete.

Der Erfindung liegt die Aufgabe zugrunde, einen Gleitschalungsfertiger zu schaffen, der insbesondere eine Verbesserung der Arbeitsbedingungen für den Maschinenführer erlaubt.The invention has for its object to provide a slipform paver which allows in particular an improvement in the working conditions for the machine operator.

Die Antriebsmittel der Antriebseinheit können die bekannten Kettenlaufwerke und Hubsäulen umfassen.The slipform paver according to the invention has a drive unit with drive means for executing translatory and / or rotary movements and a control unit which is designed in such a way that the drive means of the drive unit are controlled to carry out the translatory and / or rotary movements. The drive means of the drive unit can include the known chain drives and lifting columns.

Der erfindungsgemäße Gleitschalungsfertiger zeichnet sich dadurch aus, dass die Montageeinheit zur Befestigung einer Betonmulde um eine in Arbeitsrichtung des Gleitschalungsfertigers verlaufende Achse schwenkbar am Maschinenrahmen gelagert ist. Der Gleitschalungsfertiger verfügt über eine Schwenkeinheit, die Antriebsmittel zum Verschwenken der Montageeinheit um die in Arbeitsrichtung verlaufende Schwenkachse aufweist. Zur Fertigung von Bauteilen mit einer sich über deren Länge verändernden Ausrichtung wird die an der Montageeinheit befestigte Betonmulde mittels der Schwenkeinheit um die Schwenkachse verschwenkt, während der Maschinenrahmen seine Ausrichtung beibehält. Folglich erfordert die Fertigung des Bauteils nicht eine Veränderung der Ausrichtung des Maschinenrahmens. Da der Maschinenrahmen seine Ausrichtung beibehält, werden die Arbeitsbedingungen für den Maschinenführer verbessert. Darüber hinaus ist der Verschleiß an den Hubsäulen geringer, da die Hubsäulen nicht ein- bzw. ausgefahren werden müssen. Des Weiteren wird eine unerwünschte Schrägstellung des Förderbandes der Fördereinrichtung zum Beschicken der Betonmulde mit Beton vermieden.The slipform paver according to the invention is characterized in that the assembly unit for fastening a concrete trough is pivotally mounted on the machine frame about an axis running in the working direction of the slipform paver. The slipform paver has a swivel unit which has drive means for swiveling the assembly unit about the swivel axis running in the working direction. To manufacture components with an orientation that changes over their length, the concrete trough fastened to the assembly unit is pivoted about the pivot axis by means of the pivot unit, while the machine frame maintains its orientation. As a result, the manufacture of the component does not require a change in the orientation of the machine frame. Since the machine frame maintains its orientation, the working conditions for the machine operator are improved. In addition, there is less wear on the lifting columns, since the lifting columns do not have to be retracted or extended. In addition, an undesired inclination of the conveyor belt of the conveyor for loading the concrete trough with concrete is avoided.

Unter der Montageeinheit zur Befestigung der Betonmulde wird insbesondere eine Einheit verstanden, mit der sich Betonmulden unterschiedlicher Ausbildung schnell auswechseln lassen. Derartige Wechselvorrichtungen für Betonmulden sind dem Fachmann bekannt. Unter einer Montageeinheit kann aber auch eine Einheit verstanden werden, die keinen schnellen Wechsel der Betonmulde erlaubt. Die Betonmulde kann also grundsätzlich auch mit dem Maschinenrahmen verbunden sein, ohne ausgewechselt werden zu können.The assembly unit for fastening the concrete trough is understood in particular to mean a unit with which concrete troughs of different designs can be exchanged quickly. Such changing devices for concrete troughs are known to the person skilled in the art. An assembly unit can also be understood to mean a unit that does not allow the concrete trough to be changed quickly. In principle, the concrete trough can also be connected to the machine frame without being able to be replaced.

Zur Ausführung von Schwenkbewegungen der Montageeinheit werden die Antriebsmittel der Schwenkeinheit vorzugsweise von der zentralen Steuereinheit des Gleitschalungsfertigers angesteuert, mit der auch die Antriebsmittel der Antriebseinheit zur Ausführung der translatorischen und/oder rotatorischen Bewegungen angesteuert werden.To execute swivel movements of the assembly unit, the drive means of the swivel unit are preferably operated by the central control unit of the Controlled slipform paver, with which the drive means of the drive unit for controlling the translatory and / or rotary movements are also controlled.

Eine bevorzugte Ausführungsform sieht vor, dass die Antriebsmittel der Schwenkeinheit zur Ausführung der Schwenkbewegungen nach einem vorgegebenen Bewegungsablauf angesteuert werden, um den zu fertigenden Bauteilen die gewünschte Form zu geben. Zur Fertigung von Wasserrinnen umfasst der vorgegebene Bewegungsablauf eine Schwenkbewegung der Montageeinheit um die in Arbeitsrichtung des Gleitschalungsfertigers verlaufende Schwenkachse aus einer Neutralstellung, die einer horizontalen oder im Wesentlichen horizontalen Ausrichtung der Betonmulde entsprechen kann, in eine Schrägstellung und aus der Schrägstellung wieder in die Neutralstellung. Der vorgegebene Bewegungsablauf kann auch eine Folge von derartigen Schwenkbewegungen umfassen. Damit können Wasserrinnen gefertigt werden, deren dem Verkehrsweg zugewandte Flanken zwischen den Abläufen geneigt und an den Abläufen nicht geneigt sind.A preferred embodiment provides that the drive means of the swivel unit for executing the swivel movements are controlled according to a predetermined movement sequence in order to give the components to be manufactured the desired shape. For the production of water channels, the specified movement sequence comprises a pivoting movement of the assembly unit about the pivot axis running in the working direction of the slipform paver from a neutral position, which can correspond to a horizontal or essentially horizontal orientation of the concrete trough, into an inclined position and from the inclined position back into the neutral position. The predetermined movement sequence can also include a sequence of such pivoting movements. This allows water channels to be produced whose flanks facing the traffic route are inclined between the drains and are not inclined at the drains.

Eine besondere bevorzugte Ausbildung der Steuereinheit sieht vor, dass die einzelnen Schwenkbewegungen der Folge von Schwenkbewegungen innerhalb eines Zeitintervalls ausgeführt werden, in dem der Gleitschalungsfertiger eine vorgegebene Wegstrecke zurückgelegt hat. Bei der Fertigung von Wasserrinnen kann die vorgegebene Wegstrecke zwischen den einzelnen Schwenkbewegungen den Abständen der Abläufe an den Wasserrinnen entsprechen.A particularly preferred embodiment of the control unit provides that the individual pivoting movements resulting from the pivoting movements are carried out within a time interval in which the slipform paver has traveled a predetermined distance. When water channels are manufactured, the specified distance between the individual swiveling movements can correspond to the intervals between the processes on the water channels.

Die Antriebsmittel der Schwenkeinheit können unterschiedlich ausgebildet sein. Die Schwenkeinheit kann beispielsweise hydraulische und/oder pneumatische und/oder elektromotorische Antriebsmittel aufweisen. Vorzugsweise weist die Schwenkeinheit hydraulische Antriebsmittel auf.The drive means of the swivel unit can be designed differently. The swivel unit can have, for example, hydraulic and / or pneumatic and / or electromotive drive means. The swivel unit preferably has hydraulic drive means.

Die Montageeinheit weist Befestigungsmittel auf, die mit komplementären Befestigungsmitteln einer Montageeinheit einer Betonmulde zusammenwirken, um die Betonmulde auswechseln zu können. Die Befestigungsmittel sind vorzugsweise an einer Montageplatte der Montageeinheit angeordnet, die um eine in Arbeitsrichtung des Gleitschalungsfertigers verlaufende Achse schwenkbar gelagert ist, wobei die Antriebsmittel der Schwenkeinheit an der Montageplatte angreifen.The assembly unit has fastening means which interact with complementary fastening means of an assembly unit of a concrete trough in order to be able to replace the concrete trough. The fastening means are preferably on one Arranged mounting plate of the mounting unit, which is pivotally mounted about an axis running in the working direction of the slipform paver, the drive means of the pivot unit engaging the mounting plate.

Neben der Schwenkbewegung um die in Arbeitsrichtung des Gleitschalungsfertigers verlaufende Achse kann die Montageeinheit auch in der Höhe und/oder längs einer quer zur Arbeitsrichtung des Gleitschalungsfertigers verlaufenden Achse verstellbar an dem Maschinenrahmen angeordnet sein, um die Montageeinheit bzw. die Betonmulde unabhängig von den Schwenkbewegungen verfahren zu können.In addition to the pivoting movement about the axis running in the working direction of the slipform paver, the assembly unit can also be arranged on the machine frame so as to be adjustable in height and / or along an axis transverse to the working direction of the slipform paver, in order to move the assembly unit or the concrete trough independently of the pivoting movements can.

Eine bevorzugte Ausbildung der Steuereinheit sieht vor, dass eine Einrichtung zur Verstellung der Montageeinheit längs einer quer zur Arbeitsrichtung des Gleitschalungsfertigers verlaufenden Achse und/oder zur Verstellung der Montageeinheit in der Höhe angesteuert werden kann.A preferred embodiment of the control unit provides that a device for adjusting the assembly unit can be controlled along an axis running transversely to the working direction of the slipform paver and / or for adjusting the height of the assembly unit.

Eine besondere bevorzugte Ausbildung der Steuereinheit sieht weiterhin vor, dass die Steuereinheit derart ausgebildet ist, dass durch die Verstellung der Montageeinheit ein beliebiger Referenzpunkt der Betonmulde einen konstanten horizontalen und/oder vertikalen Abstand zu einer Referenz einhält. Dadurch können Abweichungen von dem gewünschten horizontalen und/oder vertikalen Abstand, die durch das Verschwenken der Montageeinheit hervorgerufen sind, kompensiert werden. In der Folge schwenkt die Betonmulde quasi um eine in Arbeitsrichtung des Gleitschalungsfertigers verlaufende Achse dieses beliebig wählbaren Referenzpunktes.A particularly preferred embodiment of the control unit further provides that the control unit is designed such that any reference point of the concrete trough maintains a constant horizontal and / or vertical distance from a reference by adjusting the assembly unit. This allows deviations from the desired horizontal and / or vertical distance, which are caused by the pivoting of the mounting unit, to be compensated. As a result, the concrete trough swings around an axis of this arbitrary reference point that runs in the working direction of the slipform paver.

Im Folgenden wird ein Ausführungsbeispiel der Erfindung anhand der Zeichnungen näher erläutert.An exemplary embodiment of the invention is explained in more detail below with reference to the drawings.

Fig. 1 zeigt den Gleitschalungsfertiger in der Rückansicht. Da Gleitschalungsfertiger als solche zum Stand der Technik gehören, werden hier nur die für die Erfindung wesentlichen Komponenten der Baumaschine beschrieben. Fig. 1 shows the slipform paver in the rear view. Since slipform pavers as such are part of the prior art, only the components of the construction machine that are essential to the invention are described here.

Der Gleitschalungsfertiger 1 weist einen Maschinenrahmen 2 auf, der von einem Fahrwerk getragen wird. Das Fahrwerk weist ein in Arbeitsrichtung des Gleitschalungsfertigers vorderes linkes und ein Arbeitsrichtung hinteres linkes Kettenlaufwerk 4A sowie ein in Arbeitsrichtung vorderes rechtes und ein in Arbeitsrichtung hinteres rechtes Kettenlaufwerk 4B auf, die an vorderen und hinteren linken Hubsäulen 5A sowie an vorderen und hinteren rechten Hubsäulen 5B befestigt sind. Die Arbeitsrichtung des Gleitschalungsfertigers zeigt in die Zeichenebene.The slipform paver 1 has a machine frame 2 which is supported by a chassis. The undercarriage has a front left and a working direction rear left chain drive 4A in the working direction of the slipform paver and a right and working right rear chain drive 4B in the working direction, which are attached to front and rear left lifting columns 5A and to front and rear right lifting columns 5B are. The working direction of the slipform paver points to the drawing level.

Die Kettenlaufwerke 4A, 4B und Hubsäulen 5A, 5B bilden die Antriebsmittel einer Antriebseinheit 3 zur Ausführung von translatorischen und/oder rotatorischen Bewegungen des Gleitschalungsfertigers. Durch Anheben bzw. Absenken der Hubsäulen 5A, 5B kann der Maschinenrahmen 2 gegenüber dem Boden in der Höhe verstellt werden. Dabei kann der Maschinenrahmen 2 gegenüber dem Boden in unterschiedliche Richtungen geneigt werden. Mit den Kettenlaufwerken 4A, 4B kann die Baumaschine in unterschiedliche Richtungen bewegt werden.The chain drives 4A, 4B and lifting columns 5A, 5B form the drive means of a drive unit 3 for executing translatory and / or rotary movements of the slipform paver. By raising or lowering the lifting columns 5A, 5B, the machine frame 2 can be adjusted in height relative to the floor. The machine frame 2 can be inclined in different directions with respect to the ground. With the chain drives 4A, 4B, the construction machine can be moved in different directions.

Die Antriebsmittel 4A, 4B, 5A, 5B der Antriebseinheit 3 werden zur Ausführung der translatorischen und/oder rotatorischen Bewegungen von einer in Fig. 1 nicht dargestellten zentralen Steuereinheit angesteuert. Die Steuereinheit steuert die Antriebsmittel derart an, dass der Gleitschalungsfertiger einem in Arbeitsrichtung gespannten Leitdraht 6 folgt. Anstelle eines Leitdrahtes kann der Gleitschalungsfertiger auch einer anderen Referenz folgen, die auch im Gelände bereits vorhanden sein kann, beispielsweise einem Bordstein oder einer Leitwand. Der Gleitschalungsfertiger weist eine nur andeutungsweise dargestellte Abtasteinrichtung 7 mit einem horizontalen und einem vertikalen Abtastelement 7A, 7B auf, die den Leitdraht 6 in horizontaler und vertikaler Richtung abtasten. Ein Gleitschalungsfertiger mit einer derartigen Abtasteinrichtung ist beispielsweise aus der US-A-4 041 623 bekannt.The drive means 4A, 4B, 5A, 5B of the drive unit 3 are used to perform the translatory and / or rotary movements of one in Fig. 1 controlled central control unit, not shown. The control unit controls the drive means in such a way that the slipform paver follows a guide wire 6 stretched in the working direction. Instead of a guidewire, the slipform paver can also follow another reference that may already be present in the field, for example a curb or a guide wall. The slipform paver has a scanning device 7, which is only indicated, with a horizontal and a vertical scanning element 7A, 7B, which scan the guide wire 6 in the horizontal and vertical directions. A slipform paver with such a scanning device is from, for example US-A-4 041 623 known.

Der Gleitschalungsfertiger verfügt über eine Betonmulde 8. Die auswechselbare Betonmulde 8 ist an der in Arbeitsrichtung linken Seite des Gleitschalungsfertigers mit einem Schnellwechselsystem 9 lösbar am Maschinenrahmen 2 befestigt.The slipform paver has a concrete trough 8. The exchangeable concrete trough 8 is detachably fastened to the machine frame 2 on the left side of the slipform paver in the working direction with a quick-change system 9.

Die Betonmulde 8 weist eine Schütte 8A auf, die der Zufuhr von Beton mit einer nicht dargestellten Fördereinrichtung des Gleitschalungsfertigers dient, und eine unterhalb der Schütte angeordnete Form 8B auf, die von seitlichen Platten 8C, 8D begrenzt ist.
Das Muldenschnellwechselsystem 9 weist eine dem Maschinenrahmen 2 zugeordnete Montageeinheit 10 und eine der Betonmulde 8 zugeordnete Montageeinheit 11 auf. Die Montageeinheit 10 des Maschinenrahmens 2 und die Montageeinheit 11 der Betonmulde 8 weisen jeweils eine Montageplatte 10A bzw. 11A auf, an denen jeweils Befestigungsmittel 10B bzw. 11B angeordnet sind, die ineinander greifen, wenn die Betonmulde am Maschinenrahmen 2 verriegelt ist. Ein Gleitschalungsfertiger mit einem derartigen Schnellwechselsystem zur Befestigung der Betonmulde ist beispielsweise in der DE 196 44 397 A1 beschrieben.The concrete trough 8 has a chute 8A, which is used to supply concrete with a conveyor device of the slipform paver, not shown, and a shape 8B arranged below the chute, which is delimited by side plates 8C, 8D.
The trough quick-change system 9 has an assembly unit 10 assigned to the machine frame 2 and an assembly unit 11 assigned to the concrete trough 8. The assembly unit 10 of the machine frame 2 and the assembly unit 11 of the concrete trough 8 each have a mounting plate 10A or 11A, on each of which fastening means 10B or 11B are arranged, which engage with one another when the concrete trough is locked on the machine frame 2. A slipform paver with such a quick-change system for fastening the concrete trough is, for example, in the DE 196 44 397 A1 described.

Die Montageeinheit 10 des Gleitschalungsfertigers ist am Maschinenrahmen 2 mit einer Einrichtung 12 sowohl in der Höhe als auch längs einer quer zur Arbeitsrichtung verlaufenden Achse verstellbar. Die Seitenverstellung erfolgt mittels einer horizontalen Kolbenzylinderanordnung 12A und die Höhenverstellung mit einer vertikalen Kolbenzylinderanordnung 12B. Damit kann die Betonmulde derart verfahren werden, dass ein beliebig wählbarer Referenzpunkt (R) der Betonmulde einen konstanten horizontalen Abstand (h) und/oder einen konstanten vertikalen Abstand (v) zu dem Leitdraht 6 einhält. Die Betonmulde kann dabei aber in Bezug auf den Maschinenrahmen nicht schräg gestellt werden.The assembly unit 10 of the slipform paver can be adjusted on the machine frame 2 with a device 12 both in height and along an axis running transversely to the working direction. The lateral adjustment is carried out by means of a horizontal piston cylinder arrangement 12A and the height adjustment by means of a vertical piston cylinder arrangement 12B. The concrete trough can thus be moved in such a way that an arbitrarily selectable reference point (R) of the concrete trough maintains a constant horizontal distance (h) and / or a constant vertical distance (v) from the guide wire 6. However, the concrete trough cannot be tilted in relation to the machine frame.

Der Gleitschalungsfertiger dient insbesondere zur kontinuierlichen Herstellung von Bauteilen, deren Ausrichtung sich in Arbeitsrichtung fortlaufend verändert. Dazu gehören insbesondere Wasserrinnen 13, die eine dem Verkehrsweg zugewandte innere Flanke 13A und eine dem Verkehrsweg abgewandte äußere Flanke 13B aufweisen.The slipform paver is used in particular for the continuous production of components, the orientation of which continuously changes in the working direction. This includes in particular water channels 13 which have an inner flank 13A facing the traffic route and an outer flank 13B facing away from the traffic route.

Die Montageeinheit 10 des Gleitschalungsfertigers ist am Maschinenrahmen 2 um eine in Arbeitsrichtung des Gleitschalungsfertigers verlaufende Achse 14 schwenkbar gelagert. Der Gleitschalungsfertiger weist eine Schwenkeinheit 15 auf, mit der die Betonmulde 8 um die Schwenkachse 14 verschwenkt werden kann. Die Schwenkeinheit 15 weist ein Lager 15A auf, mit dem die linke Seite der Montageplatte 10A der Montageeinheit 10 schwenkbar mit der linken Seite einer Befestigungsplatte 15B befestigt ist, die mit dem Kolben der horizontalen Kolbenzylinderanordnung 12A der Einrichtung 12 zum Verstellen der Betonmulde verbunden ist. Darüber hinaus weist die Schwenkeinheit 15 Antriebsmittel, insbesondere eine hydraulische Kolbenzylinderanordnung 15C auf, deren Kolben an der in Arbeitsrichtung rechten Seite der Montageplatte 10A und deren Zylinder an der rechten Seite der Befestigungsplatte 15B befestigt ist. Durch Ein- bzw. Ausfahren des Kolbens der Kolbenzylinderanordnung 15C kann die Betonmulde 8 um die Schwenkachse 14 verschwenkt werden.The assembly unit 10 of the slipform paver is pivotally mounted on the machine frame 2 about an axis 14 running in the working direction of the slipform paver. The slipform paver has a swivel unit 15 with which the concrete trough 8 can be swiveled about the swivel axis 14. The pivot unit 15 has a bearing 15A, with which the left side of the mounting plate 10A of the mounting unit 10 is pivotally attached to the left side of a mounting plate 15B which is connected to the piston of the horizontal piston-cylinder arrangement 12A of the device 12 for adjusting the concrete trough. In addition, the swivel unit 15 has drive means, in particular a hydraulic piston-cylinder arrangement 15C, the piston of which is fastened to the right side of the mounting plate 10A in the working direction and the cylinder of which is fastened to the right side of the fastening plate 15B. By moving the piston of the piston cylinder arrangement 15C in and out, the concrete trough 8 can be pivoted about the pivot axis 14.

Fig. 1 zeigt die Neutralstellung, in der die Betonmulde 8 nicht verschwenkt ist. Wenn der Kolben- der Kolbenzylinderanordnung 15C vollständig eingefahren ist, befindet sich die Betonmulde in der in Fig. 2 gezeigten Schrägstellung, während sich die Betonmulde in der in Fig. 3 gezeigten Schrägstellung befindet, wenn der Kolben vollständig ausgefahren ist. Die Betonmulde kann auch alle anderen Zwischenstellungen einnehmen. In der in Fig. 2 gezeigten Stellung hat die innere Flanke der Form 8B der Betonmulde 8 eine geringere Neigung als in der in Fig. 3 gezeigten Schrägstellung. Durch Ein- bzw. Ausfahren des Kolbens der Kolbenzylinderanordnung 15C kann also die der Form 8B der Betonmulde 8 entsprechende Ausrichtung der Wasserrinne 13 während des Vorschubs des Gleitschalungsfertigers kontinuierlich verändert werden. Fig. 1 shows the neutral position, in which the concrete trough 8 is not pivoted. When the piston of the piston cylinder assembly 15C is fully retracted, the concrete trough is in the in Fig. 2 shown inclination, while the concrete trough in the Fig. 3 shown inclination when the piston is fully extended. The concrete trough can also assume all other intermediate positions. In the in Fig. 2 shown position, the inner flank of the shape 8B of the concrete trough 8 has a lower inclination than in that in Fig. 3 shown inclination. By retracting or extending the piston of the piston-cylinder arrangement 15C, that of the shape 8B of the concrete trough 8 corresponding alignment of the water channel 13 can be changed continuously during the advance of the slipform paver.

Die Kolben- Zylinderanordnung 15C der Schwenkeinheit 15 wird von der zentralen Steuereinheit des Gleitschalungsfertigers angesteuert. Die zentrale Steuereinheit ist derart ausgebildet, dass für die Schwenkbewegung der Montageeinheit 10 ein bestimmter Bewegungsablauf vorgegeben werden kann. Dieser Bewegungsablauf ist eine Folge von Schwenkbewegungen, wobei die Betonmulde 8 innerhalb jeder Schwenkbewegung kontinuierlich aus der in Fig. 2 gezeigten Position in die in Fig. 3 gezeigte Position und aus der Position von Fig. 3 in die Position von Fig. 2 usw. verschwenkt wird, sodass die Neigung der inneren Flanke 13B der Regenrinne 13 beim Vorschub des Gleitschalungsfertigers kontinuierlich verändert wird. Die Daten, die den Bewegungsablauf kennzeichnen, können in einem Speicher der zentralen Steuereinheit gespeichert sein. Auch können die Daten mit einer Ein- und Ausgabeeinheit in den Speicher der Steuereinheit ein- und/oder ausgelesen werden.The piston-cylinder arrangement 15C of the swivel unit 15 is controlled by the central control unit of the slipform paver. The central control unit is designed such that a specific movement sequence can be specified for the pivoting movement of the assembly unit 10. This sequence of movements is a sequence of pivoting movements, with the concrete trough 8 continuously moving out of the position within each pivoting movement Fig. 2 position shown in the in Fig. 3 shown position and from the position of Fig. 3 in the position of Fig. 2 etc. is pivoted so that the inclination of the inner flank 13B of the rain gutter 13 is continuously changed when the slipform paver is advanced. The data that characterize the movement sequence can be stored in a memory of the central control unit. The data can also be read in and / or read out into the memory of the control unit using an input and output unit.

Darüber hinaus ist die Steuereinheit derart ausgebildet, dass die Schwenkbewegung aus der Position von Fig. 2 in die Position von Fig. 3 oder umgekehrt in einem Zeitintervall erfolgt, in dem der Gleitschalungsfertiger eine vorgegebene Wegstrecke zurückgelegt hat. Diese Wegstrecke entspricht dem vorgegebenen Abstand der Abläufe an der Wasserrinne. Die für die Bestimmung der zurückgelegten Wegstrecke erforderlichen Daten werden der Steuereinheit über einen in den Figuren nicht dargestellten Wegstreckenaufnehmer zur Verfügung gestellt, der in den bekannten Gleitschalungsfertigern im Allgemeinen ohnehin vorhanden ist.In addition, the control unit is designed such that the pivoting movement from the position of Fig. 2 in the position of Fig. 3 or vice versa takes place in a time interval in which the slipform paver has covered a predetermined distance. This distance corresponds to the specified distance of the drains on the water channel. The data required for determining the distance covered are made available to the control unit via a distance pickup, not shown in the figures, which is generally present in the known slipform pavers anyway.
