Description

Die Erfindung betrifft eine Maschine zum Eintreiben und Ziehen von Stützwandelementen, z. B. von Spundbohlen, beim Vortreiben von Gräben mit Hilfe eines Baggers. Die Gräben, die unter Verwendung einer solchen Maschine vorgetrieben werden, sind nur im Bereich der Maschine und der eingetriebenen Stützwandelemente offen, so daß im Schutz der Maschine in dem offenen Graben vorgegebene Arbeiten gefahrlos ausgeführt werden können. Auch können im Bereich des offenen Grabens Rohrleitungsschüsse, z. B. von Kanalisationsrohren, eingesenkt und aneinander angeschlossen werden. In Vortriebsrichtung hinter der Maschine wirft der Bagger den Graben wieder zu und in Vortriebsrichtung wird die Maschine nach Maßgabe des Baggeraushubes vorgeführt. Es versteht sich, daß häufig zusätzlich Stirnwandelemente vorgesehen sind und manipuliert werden müssen, die besonders angeordnet und eingerichtet sind. Das ist nicht Gegenstand dieser Erfindung.The invention relates to a machine for driving and pulling support wall elements, for. B. sheet piles, when digging trenches with the help of an excavator. The trenches that are driven using such a machine are only open in the area of the machine and the driven support wall elements, so that predetermined work can be carried out safely in the protection of the machine in the open trench. Pipeline sections, e.g. B. of sewer pipes, sunk and connected to each other. In the direction of advance behind the machine, the excavator throws the trench back and in the direction of advance, the machine is shown in accordance with the excavator excavation. It goes without saying that end wall elements are often provided and have to be manipulated, which are specially arranged and furnished. That is not the subject of this invention.

Bei der bekannten Maschine, von der die Erfindung ausgeht (EP 0 075 453 B1), sind die Treibbalken Doppelfunktionstreibbalken. Sie bedienen in der einen Funktion eintreibend bzw. ziehend die Stützwandelemente, in der anderen Funktion eintreibend und ziehend die Gegenrahmenelemente. Dazu sind die Stützwandelemente an die Treibbalken anschließbar, die entsprechende Stützwandelementaufnahmen aufweisen. Dazu sind an die Gegenrahmenelemente im Bereich ihrer Enden und im Bereich der Ecken des Gegenrahmens vertikale, statisch als Zug- und Druckbalken ausgelegte Profilelemente, die z. B. als Kastenprofile ausgeführt sind, angeschlossen, die andererseits durch Ausnehmungen im Bereich der Treibelemente hindurchgeführt sowie an diese anschließbar sind. Das Anschließen der Stützwandelemente bzw. der Profilelemente an die Treibbalken erfolgt mit Hilfe von Verbindungsbolzen, die in entsprechende Bolzenaufnahmen eingeführt sind. - Die bekannten Maßnahmen sind in montagetechnischer Hinsicht und in bedienungstechnischer Hinsicht aufwendig. In funktioneller Hinsicht sowie in bezug auf den Arbeitsablauf beim Grabenvortrieb stört insbesondere, daß während des Eintreibens und Ziehens der Stützwandelemente die Gegenrahmenelemente nicht bedient werden können - und umgekehrt. Hinzu kommt, daß der Gegenrahmen als ein geschlossenes, vorgeformtes Rahmenbauwerk ausgeführt ist, mit dem die Profilelemente entsprechend winkelsteif verbunden sind, wie es die Führung der Profilelemente in den Treibbalken verlangt.In the known machine from which the invention is based (EP 0 075 453 B1), the drive bars are double-function drive bars. They operate the retaining wall elements in one function, driving or pulling, in the other function driving and pulling the counter frame elements. For this purpose, the support wall elements can be connected to the drive beams, which have corresponding support wall element receptacles. For this purpose, the counter frame elements are in the area of their ends and in the area of the corners of the counter frame vertical, statically designed as tension and compression beams profile elements, which, for. B. are designed as box profiles connected, which on the other hand passed through recesses in the area of the driving elements and can be connected to these. The support wall elements or the profile elements are connected to the drive beam with the aid of connecting bolts which are inserted into corresponding bolt receptacles. - The known measures are complex in terms of assembly and in terms of operation. From a functional point of view as well as in relation to the workflow when digging trenches, it is particularly disturbing that the counter frame elements cannot be operated during the driving in and pulling of the support wall elements - and vice versa. In addition, the counter frame is designed as a closed, preformed frame structure, with which the profile elements are connected in an angle-resistant manner, as required by the guidance of the profile elements in the drive beam.

Demgegenüber liegt der Erfindung die Aufgabe zugrunde, eine Maschine des eingangs beschriebenen Aufbaus und der eingangs beschriebenen Zweckbestimmung in montagetechnischer und bedienungstechnischer Hinsicht zu vereinfachen, und zwar so, daß im Bedarfsfall und vorzugsweise während des Eintreibens und des Ziehens der Stützwandelemente auch die Gegenrahmenelemente bedient werden können - und umgekehrt.In contrast, the invention has for its object to simplify a machine of the construction described and the intended purpose in terms of assembly and operation, in such a way that, if necessary and preferably during the driving and pulling of the support wall elements, the counter frame elements can also be operated - and vice versa.

Zur Lösung dieser Aufgabe ist Gegenstand der Erfindung eine Maschine zum Eintreiben und Ziehen von Stützwandelementen, z. B. von Spundbohlen, beim Vortreiben von Gräben mit Hilfe eines Baggers, - mit

  • einem Maschinengestell, welches zwei in Grabenlängsrichtung verlaufende, längs des Grabenrandes angeordnete Bodenrahmenelemente und die Bodenrahmenelemente verbindende Traversen aufweist, sowie zur Führung der Stützwandelemente eingerichtet ist,
  • einem Gegenrahmen, der zwei in dem ausgehobenen Graben angeordnete, in Grabenlängsrichtung verlaufende, im Graben heb- und senkbare Gegenrahmenelemente aufweist, an denen die Stützwandelemente abstützbar sind,
  • einem in dem Maschinengestell angeordneten Treibbalken an jeder Grabenrandseite, die sich in Grabenlängsrichtung erstrecken und an den einzutreibenden oder zu ziehenden Stützwandelementen mit Verbindungseinrichtungen einzeln oder gemeinsam anschließbar sind,
wobei die Treibbalken in dem Maschinengestell angeordnet sowie mit Hilfe von Antriebseinrichtungen heb- und senkbar sind und wobei die Kombination der folgenden Merkmale verwirklicht ist:
  • a) die Treibbalken sind Einfunktionstreibbalken und besitzen für die Treibbalkenfahrt eine Antriebseinrichtung aus im Bereich der Enden der Treibbalken angeordneten Stelltrieben, die einerseits an die Treibbalken angeschlossen und andererseits in dem Maschinengestell abgestützt oder aufgehängt sowie für die Treibbalkenfahrt steuerbar sind,
  • b) die Gegenrahmenelemente sind frei von den Treibbalken und im Bereich ihrer Enden an Heb- und Senkantriebe angeschlossen sowie von diesen geführt, welche Heb- und Senkantriebe andererseits an dem Maschinengestell befestigt sowie für die Gegenrahmenfahrt steuerbar sind,
wobei die Gegenrahmenelemente quer zu ihrer Längsrichtung über Spreizelemente verbunden sind. - Das Merkmal a) ist an sich bekannt (US 3 729 938).To achieve this object, the invention relates to a machine for driving and pulling support wall elements, for. B. sheet piles, when digging trenches with the help of an excavator, - with
  • a machine frame which has two floor frame elements which run in the longitudinal direction of the trench and which are arranged along the edge of the trench and cross members which connect the floor frame elements, and is designed to guide the supporting wall elements,
  • a counter frame which has two counter frame elements which are arranged in the excavated trench and run in the longitudinal direction of the trench and can be raised and lowered in the trench and on which the supporting wall elements can be supported,
  • a drive beam arranged in the machine frame on each side of the trench, which extends in the longitudinal direction of the trench and can be connected individually or jointly to the supporting wall elements to be driven in or pulled, with connecting devices,
wherein the drive beams are arranged in the machine frame and can be raised and lowered with the aid of drive devices, and the combination of the following features is realized:
  • a) the drive beams are single-function drive beams and have a drive device for driving the drive beam from actuators arranged in the area of the ends of the drive beams, which are connected to the drive beam on the one hand and are supported or suspended in the machine frame and can be controlled for the drive beam travel,
  • b) the counter frame elements are free of the drive beams and connected to lifting and lowering drives in the region of their ends and are guided by these, which lifting and lowering drives are attached to the machine frame and can be controlled for the counter frame travel,
wherein the counter frame elements are connected transversely to their longitudinal direction via expansion elements. - The feature a) is known per se (US 3,729,938).

Bei der erfindungsgemäßen Maschine kann der Anschluß der Stützwandelemente an die Treibbalken über Verbindungsbolzen und entsprechende Bolzenaufnahmen erfolgen. Es kann aber auch mit, z. B. hydraulisch betätigten, Klemmeinrichtungen gearbeitet werden, die in die Treibbalken integriert sind. An ihre Stelltriebe sind die Treibbalken permanent angeschlossen. Entsprechend können die Gegenrahmenelemente permanent an die Heb- und Senkantriebe angeschlossen sein, was eine beachtliche montagetechnische und bedienungstechnische Vereinfachung bedeutet. - Treibbalkenfahrt meint die eintreibende und die ziehende Bewegung der Treibbalken, wie es für die Manipulation der Stützwandelemente erforderlich ist. Gegenrahmenfahrt meint entsprechend die heb- und senkende Bewegung der Gegenrahmenelemente. Es versteht sich, daß diese Bewegungen mit den Kräften durchgeführt werden müssen, die erforderlich sind, um die Stützwandelemente bzw. die Gegenrahmenelemente wie beschrieben zu bewegen.In the machine according to the invention, the support wall elements can be connected to the drive beams via connecting bolts and corresponding bolt receptacles. But it can also with, for. B. hydraulically operated, clamping devices are integrated, which are integrated in the drive beam. The drive beams are permanently connected to their actuators. Accordingly, the counter frame elements can be permanently connected to the lifting and lowering drives, which is a considerable one assembly and operational simplification means. - Driving beam means the driving and pulling movement of the driving beam, as is necessary for the manipulation of the support wall elements. Counterframe travel accordingly means the lifting and lowering movement of the counterframe elements. It is understood that these movements must be performed with the forces that are required to move the support wall elements or the counter frame elements as described.

Im einzelnen bestehen im Rahmen der Erfindung mehrere Möglichkeiten der weiteren Gestaltung und Ausbildung der erfindungsgemäßen Maschine. So können die Stelltriebe der Treibbalken als Zylinder/Kolben-Anordnungen ausgeführt sein. Auch die Heb- und Senkantriebe der Gegenrahmenelemente können als Zylinder/Kolben-Anordnungen ausgeführt sein. Man kann aber auch mit Zahnstangen und Zahnradantrieben bzw. Schraubenspindel und Spindelantrieben arbeiten. In Rahmen der Erfindung liegt es, die Anordnung so zu treffen, daß die Heb- und Senkantriebe der Gegenrahmenelemente ihrerseits an bereits eingetriebenen Stützwandelementen mit Hilfe von Führungshilfselementen geführt sind. Es können aber auch die Heb- und Senkantriebe der Gegenrahmenelemente ihrerseits an bereits eingetriebenen zusätzlichen Stützen mit Hilfe von Führungshilfselementen geführt sein.In particular, there are several possibilities for further design and development of the machine according to the invention within the scope of the invention. For example, the actuators of the drive beams can be designed as cylinder / piston arrangements. The lifting and lowering drives of the counter frame elements can also be designed as cylinder / piston arrangements. But you can also work with racks and gear drives or screw spindles and spindle drives. It is within the scope of the invention to make the arrangement such that the lifting and lowering drives of the counter frame elements are in turn guided on support wall elements that have already been driven in with the aid of guide auxiliary elements. However, the lifting and lowering drives of the counter frame elements can in turn be guided on additional supports that have already been driven in with the aid of auxiliary guide elements.

Nach einer bevorzugten Ausführungsform der Erfindung sind die Stelltriebe der Treibbalken einerseits und die Heb- und Senkantriebe der Gegenrahmenelemente andererseits als baulich selbständige und funktionell unabhängige Antriebe ausgeführt. Es kann aber auch die Anordnung so getroffen sein, daß die Stelltriebe der Treibbalken und die Heb- und Senkantriebe als baulich einheitlich, funktionell differenzierte Antriebe ausgeführt sind, die für die sogenannte Treibbalkenfahrt einerseits und die Gegenrahmenfahrt andererseits unterschiedlich steuerbar sind. Nach einem spezielleren Vorschlag der Erfindung sind in diesem Zusammenhang die Stelltriebe der Treibbalken und die Heb- und Senkantriebe als Doppelzylinder/Kolben-Anordnungen mit jeweils zwei Kolbenstangen ausgeführt, deren eine an den zugeordneten Treibbalken und deren andere an das zugeordnete Gegenrahmenelement angeschlossen sind. Man kann dabei den Treibbalken bei Gegenrahmenfahrt funktionslos mitführen. Ein anderer Vorschlag der Erfindung geht dahin, daß die Gegenrahmenelemente bei Treibbalkenfahrt von den Antrieben abkuppelbar sind.According to a preferred embodiment of the invention, the actuators of the drive beams on the one hand and the lifting and lowering drives of the counter frame elements on the other hand are designed as structurally independent and functionally independent drives. However, the arrangement can also be such that the actuators of the drive beam and the lifting and lowering drives are designed as structurally uniform, functionally differentiated drives which can be controlled differently for the so-called drive beam travel and the counterframe travel on the other hand. According to a more specific proposal of the invention, the actuators of the drive beam and the lifting and lowering drives are designed as double cylinder / piston arrangements, each with two piston rods, one of which is connected to the associated drive beam and the other to the associated counter frame element. You can carry the drive beam without function when driving the counter frame. Another proposal of the invention is that the counter frame elements can be uncoupled from the drives during driving beam travel.

Von besonderer Bedeutung ist eine Ausführungsform der erfindungsgemäßen Maschine, bei der die Gegenrahmenelemente im Bereich ihrer Enden an vertikale Gegenrahmenprofile angeschlossen sind, die ihrerseits im Maschinengestell geführt sind, und wobei die Heb- und Senkantriebe zwischen dem Maschinengestell und den Gegenrahmenprofilen angeordnet sind. Im Rahmen dieser Grundkonzeption kann das Maschinengestell auf verschiedene Weise ausgebildet sein. Nach bevorzugter Ausführungsform der Erfindung weist hier das Maschinengestell die Bodenrahmenelemente und daran über Stützen angeschlossene Führungstraversen für die Gegenrahmenprofile auf, wobei die Heb- und Senkantriebe im Bereich der Enden der Führungsrahmentraversen angeordnet sind. Im Rahmen der Erfindung liegt es bei dieser Ausführungsform, die vertikalen Gegenrahmenprofile als Stützwandelemente auszubilden. Auch bei dieser Ausführungsform der Erfindung können die Heb- und Senkantriebe unterschiedlich ausgeführt sein. Im einfachsten Falle wird man die Heb- und Senkantriebe als Zylinder/Kolbenanordnungen ausführen. Durch Einfachheit und Funktionssicherheit ausgezeichnet ist eine Ausführungsform der Erfindung des zuletzt beschriebenen Aufbaus, wobei der Gegenrahmen und die vertikalen Gegenrahmenprofile zu einem ausreichend winkelsteifen Rahmenprofil vereinigt sind, in welches im Verbundzustand die Führungstraversen, vorzugsweise wiederum winkelsteif, integriert sind, - während die Treibbalken von dem Rahmentragwerk unabhängig zu betätigen sind, - und umgekehrt.Of particular importance is an embodiment of the machine according to the invention, in which the counter frame elements are connected in the region of their ends to vertical counter frame profiles, which in turn are guided in the machine frame, and the lifting and lowering drives are arranged between the machine frame and the counter frame profiles. As part of this basic concept, the machine frame can be used in different ways Be trained. According to a preferred embodiment of the invention, the machine frame here has the base frame elements and guide cross members connected thereto via supports for the counter frame profiles, the lifting and lowering drives being arranged in the region of the ends of the guide frame cross members. It is within the scope of the invention in this embodiment to design the vertical counter frame profiles as supporting wall elements. In this embodiment of the invention, the lifting and lowering drives can be designed differently. In the simplest case, the lifting and lowering drives will be designed as cylinder / piston arrangements. An embodiment of the invention of the structure described last is distinguished by simplicity and functional reliability, the counterframe and the vertical counterframe profiles being combined to form a sufficiently angularly rigid frame profile, in which the guide crossbars, preferably again angularly rigid, are integrated in the bonded state, while the drive beams from it The framework must be operated independently, and vice versa.

Aus einer vergleichenden Betrachtung der Fig. 1 und 2 bzw. 3 entnimmt man, daß die Treibbalken 7 Einfunktionstreibbalken sind. Sie besitzen für die Treibbalkenfahrt, d. h. die Aufundniederbewegung der Treibbalken 7, eine Antriebseinrichtung 9 aus im Bereich der Enden der Treibbalken 7 angeordneten Stelltrieben 10, die einerseits an die Treibbalken 7 angeschlossen und andererseits in dem Maschinengestell 2 abgestützt oder aufgehängt sowie für die Treibbalkenfahrt steuerbar sind. Zum grundsätzlichen Aufbau gehören fernerhin Gegenrahmenelemente 6, die frei von den Treibbalken 7 sind und im Bereich ihrer Enden an Heb- und Senkantriebe 11 angeschlossen sind. Sie sind außerdem von diesen geführt. Die Heb- und Senkantriebe 11 sind an dem Maschinengestell 2 befestigt sowie für die Gegenrahmenfahrt steuerbar. Die Anordnung ist im übrigen so getroffen, daß die Gegenrahmenelemente 6 quer zu ihrer Längsrichtung über Spreizelemente 12 verbunden sind. Diese Spreizelemente 12 können so ausgeführt sein, daß damit die Gegenrahmenelemente 6 gegen die Stützwandelemente 1 fahrbar sind.From a comparative view of FIGS. 1 and 2 and 3, it can be seen that the drive beams 7 are single-function drive beams. They have a drive device 9 for the drive beam travel, ie the up and down movement of the drive beams 7, of actuators 10 arranged in the region of the ends of the drive beams 7, which are connected on the one hand to the drive beam 7 and on the other hand supported or suspended in the machine frame 2 and controllable for the drive beam travel . The basic structure also includes counterframe elements 6, which are free from the drive beam 7 and are connected to lifting and lowering drives 11 in the region of their ends. They are also led by them. The lifting and lowering drives 11 are fastened to the machine frame 2 and can be controlled for the counter frame travel. The arrangement is otherwise made so that the counter frame elements 6 are connected transversely to their longitudinal direction via expansion elements 12. These expansion elements 12 can be designed so that the counter frame elements 6 are movable against the support wall elements 1.

Im Ausführungsbeispiel und nach bevorzugter Ausführungsform der Erfindung sind die Stelltriebe 10 der Treibbalken 7 als Zylinder/Kolben-Anordnungen ausgeführt. Andererseits sind Heb- und Senkantriebe 11 der Gegenrahmenelemente 6 als Zylinder/Kolben-Anordnungen ausgeführt. Die Anordnung ist konkret so getroffen, daß die Heb- und Senkantriebe 11 der Gegenrahmenelemente 6 ihrerseits an bereits eingetriebene Stützwandelemente 1 mit Hilfe von Führungshilfsmitteln 13 geführt sind. Man könnte aber auch die Heb- und Senkantriebe 11 der Gegenrahmenelemente 6 über zusätzliche Stützen, die eingetrieben sind, mit Hilfe von Führungshilfselementen führen.In the exemplary embodiment and according to a preferred embodiment of the invention, the actuators 10 of the drive beam 7 are designed as cylinder / piston arrangements. On the other hand, lifting and lowering drives 11 of the counter frame elements 6 are designed as cylinder / piston arrangements. The arrangement is specifically such that the lifting and lowering drives 11 of the counter frame elements 6 are in turn guided to support wall elements 1 that have already been driven in with the aid of guide aids 13. However, one could also guide the lifting and lowering drives 11 of the counter frame elements 6 via additional supports which are driven in with the aid of guide auxiliary elements.

Bei der Ausführungsform nach den Fig. 1 und 2 sind die Stelltriebe 10 der Treibbalken 7 einerseits und die Heb- und Senkantriebe 11 der Gegenrahmenelemente 6 andererseits als baulich selbständige und funktionell unabhängige Antriebe ausgeführt. In den Fig. 3 und 4 erkennt man, daß die Stelltriebe 10 der Treibbalken 7 und die Heb- und Senkantriebe 11 als baulich einheitliche, jedoch funktionell differenzierte Antriebe ausgeführt sind, die für die sogenannte Treibbalkenfahrt einerseits und die Gegenrahmenfahrt andererseits unterschiedlich steuerbar sind.In the embodiment according to FIGS. 1 and 2, the actuators 10 of the drive beam 7 on the one hand and the lifting and lowering drives 11 of the counter frame elements 6 on the other hand are designed as structurally independent and functionally independent drives. 3 and 4 it can be seen that the actuators 10 of the drive beam 7 and the lifting and lowering drives 11 are designed as structurally uniform, but functionally differentiated drives which can be controlled differently for the so-called drive beam travel on the one hand and the counter frame travel on the other hand.

In der Fig. 3 wurde angedeutet, daß die Stelltriebe 10 der Treibbalken 7 und die Heb- und Senkantriebe 11 als Doppelzylinder/Kolben-Anordnungen 14 mit jeweils zwei Kolbenstangen 15 ausgeführt sind, deren eine an den zugeordneten Treibbalken 7 und deren andere an das zugeordnete Gegenrahmenelement 6 angeschlossen ist. Die Treibbalken 7 können bei Gegenrahmenfahrt funktionslos mitgeführt werden, wobei die Gegenrahmenelemente 6 bei Treibbalkenfahrt von den Antrieben abkuppelbar sind.In Fig. 3 it was indicated that the actuators 10 of the drive beam 7 and the lifting and lowering drives 11 are designed as double cylinder / piston assemblies 14, each with two piston rods 15, one of which on the assigned drive beam 7 and the other of which is connected to the assigned counter frame element 6. The drive beam 7 can be carried functionless when driving the counter frame, the counter frame elements 6 can be uncoupled from the drives when driving the beam.

Eine Ausführungsform einer erfindungsgemäßen Maschine, die sich in montagetechnischer und bedienungstechnischer Hinsicht durch besondere Einfachheit auszeichnet, zeigt die Fig. 4. Man erkennt, daß die Gegenrahmenelemente 6 im Bereich ihrer Enden an vertikale Gegenrahmenprofile 17 angeschlossen sind, die ihrerseits im Maschinengestell 2 geführt sind, wobei die Heb- und Senkantriebe 11 zwischen dem Maschinengestell 2 und den Gegenrahmenprofilen 17 angeordnet sind. Dabei kann das Maschinengestell 2 die Bodenrahmenelemente 3 und daran über Stützen 18 angeschlossene Führungstraversen 19 für die Gegenrahmenprofile 17 aufweisen, wie es die Figur darstellt. Die Heb- und Senkantriebe 11 sind im Bereich der Enden der Führungstraversen 19 angeordnet. - In Abweichung von der in Fig. 4 dargestellten Ausführungsform können die vertikalen Gegenrahmenprofile 17 als Stützwandelemente ausgebildet sein. Die Heb- und Senkantriebe 11 sind im Ausführungsbeispiel Zylinder/Kolbenanordnungen. Im Ausführungsbeispiel der Fig. 4 und nach bevorzugter Ausführungsform der Erfindung sind der Gegenrahmen 5 und die vertikalen Gegenrahmenprofile 17 zu einem ausreichend winkelsteifen Rahmentragwerk 5, 17 vereinigt, in welches im Verbundzustand die Führungstraversen 19, vorzugsweise ebenfalls winkelsteif, integriert sind. Man entnimmt aus der Fig. 4, daß die Treibbalken 7 von dem Rahmentragwerk 5, 17, 19 unabhängig zu betätigen sind, - und umgekehrt.An embodiment of a machine according to the invention, which is particularly simple in terms of assembly and operation, is shown in FIG. 4. It can be seen that the counter frame elements 6 are connected in the region of their ends to vertical counter frame profiles 17, which in turn are guided in the machine frame 2, wherein the lifting and lowering drives 11 are arranged between the machine frame 2 and the counter frame profiles 17. In this case, the machine frame 2 can have the base frame elements 3 and guide crosspieces 19 for the counter frame profiles 17 connected thereto via supports 18, as shown in the figure. The lifting and lowering drives 11 are arranged in the region of the ends of the guide cross members 19. - In deviation from the embodiment shown in Fig. 4, the vertical counter frame profiles 17 can be designed as supporting wall elements. The lifting and lowering drives 11 are cylinder / piston arrangements in the exemplary embodiment. In the exemplary embodiment of FIG. 4 and according to a preferred embodiment of the invention, the counter frame 5 and the vertical counter frame profiles 17 are combined to form a sufficiently angularly rigid frame structure 5, 17, in which, in the connected state, the guide cross members 19, preferably also angularly rigid, are integrated. It can be seen from FIG. 4 that the drive beams 7 can be operated independently of the frame structure 5, 17, 19, and vice versa.

Zum weiteren Verständnis der Ausführungsform nach Fig. 4 wird auf die Fig. 2 verwiesen, aus der der Fachmann entnimmt, wie die Ausführungsform nach Fig. 4 in einem der Fig. 2 entsprechenden Schnitt aussehen würde.For a further understanding of the embodiment according to FIG. 4, reference is made to FIG. 2, from which the person skilled in the art will see how the embodiment according to FIG. 4 would look in a section corresponding to FIG. 2.
