Description

Anlage zur Herstellung von Fahrwegelementen Plant for the production of track elements
Die vorliegende Erfindung betrifft eine Anlage zur Herstellung von Fahrwegelementen.The present invention relates to a system for producing guideway elements.
Fahrwege, insbesondere Schienenfahrwege und hier insbeson- dere Schienenfahrwege für Magnetschwebebahnen, werden aus einzelnen Fahrwegelementen zusammengesetzt. Bei vom Markt her bekannten Fahrwegelementen für eine Magnetschwebebahn handelt es sich um Betonteile, welche vor Ort hergestellt werden. Um die Fertigung zu vereinfachen und die Herstell- kosten zu senken, sollen die Fahrwegelemente künftig als Metallteile in einer Fabrik vorgefertigt werden. Diese Metallteile sollen dann an die Fahrwegbaustelle verbracht und dort so miteinander verbunden werden, daß ein möglichst kontinuierlicher Verlauf des Fahrweges auch bei unter- schiedlichen Geländeprofilen realisiert wird. Die für einTravel routes, in particular rail travel routes and in particular rail travel routes for magnetic levitation trains, are composed of individual travel route elements. Track elements known from the market for a magnetic levitation train are concrete parts which are manufactured on site. In order to simplify production and reduce manufacturing costs, the guideway elements are to be prefabricated as metal parts in a factory in the future. These metal parts are then to be brought to the track construction site and connected there in such a way that the course of the track is as continuous as possible, even with different terrain profiles. The one
Projekt einer Magnetschwebebahn geplanten Fahrwegelemente sind z.B. 62 m lang und werden auf Stützen oberhalb der Bodenoberfläche angeordnet. Bei diesen Fahrwegelementen handelt es sich um Stahlbauteile aus dickwandigem Stahlblech. Im Querschnitt verfügen diese Fahrwegelemente über ein trapezförmiges Kastenprofil mit zwei in Einbaulage oberen transversalen Auslegern, so daß man insgesamt einen in etwa T-förmigen Querschnitt erhält.Project of a magnetic levitation planned route elements are e.g. 62 m long and are arranged on supports above the ground surface. These guideway elements are steel components made of thick-walled sheet steel. In cross section, these guideway elements have a trapezoidal box section with two upper transverse brackets in the installed position, so that an approximately T-shaped cross section is obtained overall.
Zwar sind die besagten Fahrwegelemente alle in etwa gleich lang, sie unterscheiden sich jedoch hinsichtlich ihrer Detailgeometrie. Darunter ist z.B. eine individuelle Krümmung um eine vertikale Achse (Kurvenkrümmung) und um eine quer zur Längsachse des Fahrwegelements verlaufende horizontale Achse (Höhenprofil) zu verstehen. Diese geometrischen Ei- genschaften werden für jedes Fahrwegelement individuell entsprechend den geographischen Gegebenheiten an der Stelle festgelegt, an der das jeweilige Fahrwegelement verbaut werden soll.Although the said track elements are all of approximately the same length, they differ with regard to their detailed geometry. This includes, for example, an individual curvature about a vertical axis (curve curvature) and about a horizontal axis (height profile) running transverse to the longitudinal axis of the guideway element. This geometric egg Properties are individually defined for each route element in accordance with the geographical conditions at the point at which the respective route element is to be installed.
Trotz der auf diese Weise relativ komplexen und individuell unterschiedlichen Detailgeometrie der einzelnen Fahrwegelemente ist bei der Herstellung eine hohe Präzision gefordert. Bei den besagten Fahrwegelementen ist bei einer Ge- samtlänge eines Fahrwegelements von ungefähr 62 m an den Stoßstellen eine Fertigungstoleranz von maximal 1 mm gestattet . Um diesen hohen Genauigkeitsforderungen genügen zu können, werden an die Anlagen, in denen die einzelnen Fahrwegelemente vorgefertigt werden, ebenfalls sehr hohe Anfor- derungen gestellt. Dabei sollen die Anlagen selbst und auch die Herstellung der Fahrwegelemente möglichst preiswert sein. Die Fahrwegelemente werden zunächst auf einer Anlage, welche Spannvorrichtungen umfaßt, vormontiert. In einer weiteren Anlage sollen die Fahrwegelemente dann mechanisch bearbeitet, z. B. gebohrt, gefräst und entgratet werden. Hierfür ist die in Anspruch 1 angegebene erfindungsgemäße Anlage gedacht .Despite the relatively complex and individually different detail geometry of the individual guideway elements in this way, high precision is required during manufacture. With the said guideway elements, with a total length of a guideway element of approximately 62 m, a maximum manufacturing tolerance of 1 mm is permitted at the joints. In order to be able to meet these high accuracy requirements, the systems in which the individual guideway elements are prefabricated also have to meet very high requirements. The systems themselves and the production of the track elements should be as inexpensive as possible. The guideway elements are first preassembled on a system which includes clamping devices. In a further system, the guideway elements are then to be machined, e.g. B. drilled, milled and deburred. The system according to the invention specified in claim 1 is intended for this.
Die erfindungsgemäße Anlage ist aus einer Mehrzahl von in Anlagenlängsrichtung hintereinander angeordneten Haltevorrichtungen mit Auflagereinrichtungen aufgebaut . Die Aufla- gereinrichtungen sind dabei jeweils so in ihrer Position verstellbar, daß jede Auflagereinrichtung an die individuelle Geometrie und Position jenes Abschnitts eines Fahrwe- gelements angepaßt werden kann, der auf ihn aufgelegt werden soll. Die Auflagereinrichtung ist dabei so ausgebildet, daß das Fahrwegelement in seiner im wesentlichen der späteren Einbaulage entsprechenden Ausrichtung aufgelegt werden kann. Auf diese Weise wird eine Art "Bett" geschaffen, wel- ches die individuelle Detailgeometrie des jeweilige Fahrwe- gelements wiedergibt. Aufgrund der Verstellbarkeit können unterschiedliche Fahrwegelemente unter Benutzung der gleichen Anlage hergestellt werden, wodurch die Anlagenkosten und die Herstellkosten der einzelnen Fahrwegelemente erheb- lieh gesenkt werden.The system according to the invention is constructed from a plurality of holding devices with support devices arranged one behind the other in the longitudinal direction of the system. The support devices can each be adjusted in their position so that each support device can be adapted to the individual geometry and position of that section of a travel element that is to be placed on it. The support device is designed so that the guideway element can be placed in its orientation that essentially corresponds to the later installation position. In this way, a kind of "bed" is created, which the individual detailed geometry of the respective driving reproduces elements. Because of the adjustability, different guideway elements can be produced using the same system, whereby the system costs and the manufacturing costs of the individual guideway elements are significantly reduced.

Eine Anlage zur Herstellung von Fahrwegelementen trägt in Figur 1 insgesamt das Bezugszeichen 10. Sie umfaßt eine im Boden vorhandene längliche, in der Draufsicht rechteckige Vertiefung 12, in der über ihre Länge verteilt insgesamt 11 Haltevorrichtungen angeordnet sind.A system for the production of guideway elements has the overall reference number 10 in FIG. 1. It comprises an elongated depression 12, which is rectangular in plan view and in which a total of 11 holding devices are arranged over its length.
Die beiden Haltevorrichtungen an den jeweiligen Enden der Vertiefung 12 sowie die mittlere Haltevorrichtung sind als Hauptlager-Aufnahmevorrichtung 14 ausgebildet . Die zwischen zwei solchen Hauptlager-Aufnahmevorrichtungen 14 angeordneten Haltevorrichtungen sind als Spann- und Dämpfvorrichtung 16 ausgebildet. Die Länge der Vertiefung 12 ist etwas grö- ßer als die Länge eines Fahrwegelements (in Figur 1 nicht dargestellt) . Die Abstände zwischen den einzelnen Haltevorrichtungen, also den Hauptlager-Aufnahmevorrichtungen 14 und den Spann- und DämpfVorrichtungen 16, sind bei dem in Figur 1 dargestellten Ausführungsbeispiel gleich. Sie kön- nen jedoch, je nach Art des herzustellenden Fahrwegelements, auch variieren. Zu diesem Zweck sind die Hauptlager- Aufnahmevorrichtungen 14 und die Spann- und Dämpfvorrichtungen 16 auf Schienen 18 in Längsrichtung der Anlage 10 verfahrbar, wie weiter unten noch genauer erläutert ist.The two holding devices at the respective ends of the recess 12 and the middle holding device are as Main bearing receiving device 14 is formed. The holding devices arranged between two such main bearing receiving devices 14 are designed as tensioning and damping devices 16. The length of the depression 12 is somewhat greater than the length of a guideway element (not shown in FIG. 1). The distances between the individual holding devices, that is to say the main bearing receiving devices 14 and the tensioning and damping devices 16, are the same in the exemplary embodiment shown in FIG. However, they can also vary depending on the type of route element to be manufactured. For this purpose, the main bearing receiving devices 14 and the tensioning and damping devices 16 can be moved on rails 18 in the longitudinal direction of the system 10, as will be explained in more detail below.
Eine der Hauptlager-Aufnahmevorrichtungen 14 wird nun unter Bezugnahme auf die Figuren 2 und 3 im Detail erläutert . Es versteht sich, daß die einzelnen Hauptlager-Aufnahmevorrichtungen 14 der Anlage 10 alle identisch sein können.One of the main bearing receiving devices 14 will now be explained in detail with reference to FIGS. 2 and 3. It is understood that the individual main bearing receiving devices 14 of the system 10 can all be identical.
Die Hauptlager-Aufnahmevorrichtung 14 umfaßt ein Basiselement 20, ein auf diesem angeordnetes unteres Zwischenelement 22, ein mit dem unteren Zwischenelement 22 über insgesamt vier vertikale Stützelemente 24 verbundenes oberes Zwischenelement 26 und zwei oberhalb des Zwischenelements 26 angeordnete Auflagereinrichtungen 28. Auf diesen liegt ein Hauptlager 30 eines vormontierten Fahrwegelements 32 so auf, daß das Fahrwegelement 32 entsprechend seiner späteren Einbaulage ausgerichtet ist .The main bearing receiving device 14 comprises a base element 20, a lower intermediate element 22 arranged thereon, an upper intermediate element 26 connected to the lower intermediate element 22 via a total of four vertical support elements 24, and two bearing devices 28 arranged above the intermediate element 26. A main bearing 30 lies thereon a preassembled guideway element 32 so that the guideway element 32 is aligned according to its later installation position.
Beim Basiselement 20 handelt es sich um einen Laufwagen, welcher insgesamt vier Räder 34 aufweist, die in Radkästen 35 untergebracht sind und auf den Schienen 18 in der Vertiefung 12 laufen. Mindestens eines der Räder 34 wird von einem Elektromotor 36 angetrieben, so daß sich das Basiselement 20 auf den Schienen 18 bewegen kann. Das Basiselement 20 hat in der Draufsicht in etwa rechteckige Grundform und ist aus Doppel-T-Trägern 38 und einer unteren Deckplatte 40 sowie einer oberen Deckplatte 42 aufgebaut. An der unteren Deckplatte 40 ist ein sich in Anlagenlängsrichtung erstreckendes Führungsstück 44 befestigt, welches in einer aus einem U-Profil gebildeten Führungsschiene 46 geführt ist. Auf diese Weise wird die Hauptlager- AufnähmeVorrichtung 14 bei ihrer Bewegung auf den Schienen 18 in seitlicher Richtung zusätzlich sicher geführt.The base element 20 is a carriage which has a total of four wheels 34, which are accommodated in wheel housings 35 and run on the rails 18 in the depression 12. At least one of the wheels 34 is driven by an electric motor 36, so that the Base element 20 can move on the rails 18. The base element 20 has an approximately rectangular basic shape in plan view and is composed of double-T beams 38 and a lower cover plate 40 and an upper cover plate 42. A guide piece 44, which extends in the longitudinal direction of the system and is guided in a guide rail 46 formed from a U-profile, is fastened to the lower cover plate 40. In this way, the main bearing receiving device 14 is additionally guided securely when it moves on the rails 18 in the lateral direction.
Auf die obere Deckplatte 42 ist zwischen den seitlichen Radkästen 35 ein Führungsteil 48 montiert, welches einen mittigen, sich quer zur Anlagenlängsrichtung erstreckenden Steg 50 sowie zwei sich ebenfalls quer zur Anlagenlängsrichtung erstreckende seitliche Vorsprünge 52 und 54 aufweist. Auf dem Führungsteil 48 liegt das als Schlitten ausgebildete untere Zwischenelememt 22 auf, welches eine mittige Nut 56 aufweist, in die der mittige Steg 50 des Füh- rungsteils 48 eingreift, und dessen in Anlagenlängsrichtung gesehen vordere und hintere Randbereiche 58 und 60 so ausgebildet sind, daß sie die seitlichen Vorsprünge 52 und 54 des Führungsteils 48 übergreifen. Auf diese Weise ist das untere Zwischenelement 22 auf dem Basiselement 20 in in An- lagenlängsrichtung gesehen seitlicher Richtung verschieb- lich geführt .On the upper cover plate 42, a guide part 48 is mounted between the side wheel arches 35, which has a central web 50, which extends transversely to the longitudinal direction of the plant, and two lateral projections 52 and 54, which also extend transversely to the longitudinal direction of the plant. The lower intermediate element 22, which is designed as a slide, lies on the guide part 48 and has a central groove 56, into which the central web 50 of the guide part 48 engages and whose front and rear edge regions 58 and 60 are formed in the longitudinal direction of the system, that they overlap the lateral projections 52 and 54 of the guide member 48. In this way, the lower intermediate element 22 is displaceably guided on the base element 20 in the lateral direction as seen in the longitudinal direction of the plant.
Der Spalt zwischen dem unteren Zwischenelement 22 und den Radkästen 35 ist zu beiden Seiten durch Lamellenabdeckungen 62 geschlossen. Zur Bewegung des Zwischenelements 22 gegenüber dem Basiselement 20 ist ein Elektromotor vorgesehen, welcher jedoch in den Figuren nicht sichtbar ist.The gap between the lower intermediate element 22 and the wheel arches 35 is closed on both sides by lamella covers 62. An electric motor is provided for moving the intermediate element 22 relative to the base element 20, but is not visible in the figures.
Auf der Oberseite des Basiselements 20 sind im Bereich sei- ner vier Ecken vier elektrische Stellantriebe 64 angeord- net, welche auf die vertikalen Stützelemente 24 arbeiten, so daß diese vertikal verschieblich sind. Die elektrischen Stellantriebe 64 sind über Wellen 66 mit einem mittig auf dem unteren Zwischenelement 22 angeordneten zentralen Zwangs-Synchronisiergetriebe 68 verbunden. Auf diese Weise ist sichergestellt, daß sich die vertikalen Stützelemente 24 linear und mit jeweils identischem Hub bewegen.Four electrical actuators 64 are arranged on the top of the base element 20 in the area of its four corners. net, which work on the vertical support elements 24 so that they are vertically displaceable. The electric actuators 64 are connected via shafts 66 to a central forced synchronizing gear 68 arranged centrally on the lower intermediate element 22. This ensures that the vertical support elements 24 move linearly and with an identical stroke.
Auf dem unteren Zwischenelement 22 sind ferner ebenfalls im Bereich seiner Ecken angeordnete Führungsblöcke 70 vorgesehen, in denen am oberen Zwischenelement 26 befestigte vertikale Führungsstäbe 72 geführt sind. Die Vertikalbewegung der vertikalen Stützelemente 24 und der Führungsstäbe 72 nach unten wird durch in der Figur nicht sichtbare Durch- brüche in der oberen Deckplatte 42 des Basiselements 20 ermöglicht .Guide blocks 70 are also provided on the lower intermediate element 22 in the region of its corners, in which vertical guide rods 72 fastened to the upper intermediate element 26 are guided. The vertical movement of the vertical support elements 24 and the guide rods 72 downward is made possible by openings in the upper cover plate 42 of the base element 20 that are not visible in the figure.
Das obere Zwischenelement 26 ist ähnlich wie das Basiselement 20 aus in Längs- und Querrichtung verlaufenden Doppel- T-Trägern 74, einer unteren Deckplatte 76 und einer oberen Deckplatte 78 aufgebaut. Der zwischen oberem Zwischenelement 26 und unterem Zwischenelement 22 aufgespannte Raum ist seitlich durch in vertikaler Richtung elastische Faltwände 80 verschlossen.Similar to the base element 20, the upper intermediate element 26 is constructed from double T-beams 74 running in the longitudinal and transverse directions, a lower cover plate 76 and an upper cover plate 78. The space spanned between the upper intermediate element 26 and the lower intermediate element 22 is closed laterally by folding walls 80 which are elastic in the vertical direction.
Auf der oberen Deckplatte 78 des oberen Zwischenelements 26 liegt eine Grundplatte 82 für die Auflagereinrichtungen 28 auf. Diese weist eine mittige Lagerbuchse 84 auf, in die ein an die obere Deckplatte 78 des oberen Zwischenelements 26 festgeschweißter Lagerbolzen 86 eingreift. Auf dieseA base plate 82 for the support devices 28 rests on the upper cover plate 78 of the upper intermediate element 26. This has a central bearing bush 84, into which a bearing bolt 86 which is welded to the upper cover plate 78 of the upper intermediate element 26 engages. To this
Weise ist die Grundplatte 82 gegenüber dem oberen Zwischenelement 26 um eine vertikale Achse verschwenkbar. Die Gleitbewegung der Grundplatte 82 gegenüber der oberen Deckplatte 78 des oberen Zwischenelements 26 wird dabei durch in den Figuren nicht sichtbare Gleitlager erleichtert. Die Bewegung selbst wird durch einen Elektromotor 88 bewirkt, der eine Welle 90 antreibt.The base plate 82 is pivotable relative to the upper intermediate element 26 about a vertical axis. The sliding movement of the base plate 82 relative to the upper cover plate 78 of the upper intermediate element 26 is facilitated by plain bearings which are not visible in the figures. The movement itself is brought about by an electric motor 88 which drives a shaft 90.
Auf der Grundplatte 82 sind in der Nähe ihrer in Anlagen- längsrichtung gesehen seitlichen Ränder zwei Führungsplatten 92 montiert, die das unterste Element der jeweiligen Auflagereinrichtung 28 darstellen und in deren sich quer zur Anlagenlängsrichtung erstreckende horizontale Ränder jeweils eine Nut 94 eingebracht ist. In diese greifen jeweils seitliche Führungsabschnitte 96 eines Schlittens 98. Dieser trägt einen Elektromotor 100, der eine Spindel 102 antreibt, welche wiederum mit einem Gewindeabschnitt 104 der entsprechenden Führungsplatte 92 zusammenarbeitet. Auf diese Weise können die Schlitten 98 gegenüber den Führungsplatten 92 in in Anlagenlängsrichtung gesehen seitlicher Richtung unabhängig voneinander bewegt werden .Two guide plates 92 are mounted on the base plate 82 in the vicinity of their lateral edges, as seen in the longitudinal direction of the plant, which represent the lowest element of the respective support device 28 and in each of which a groove 94 is introduced, which extends transversely to the longitudinal direction of the plant. Lateral guide sections 96 of a slide 98 engage in each of these. This carries an electric motor 100 which drives a spindle 102, which in turn cooperates with a threaded section 104 of the corresponding guide plate 92. In this way, the carriages 98 can be moved independently of one another in relation to the guide plates 92 in the lateral direction as seen in the longitudinal direction of the system.
In die oberen Ränder der beiden Schlitten 98 ist eine kreissegmentförmige Ausnehmung 106 eingebracht, in der jeweils ein komplementärer Lagerabschnitt 108 eines Auflagerelements 110 gelagert ist. Längs der Begrenzungsfläche der kreissegmentförmigen Ausnehmung 106 können Wälz- oder Gleitlager vorhanden sein, welche die Relativ- bewegung des Lagerabschnitts 108 des Auflagerelements 110 gegenüber der Ausnehmung 106 des Schlittens 98 erleichtern. Hierdurch ist eine freie Bewegung der beiden Auflagerelemente 110 gegenüber dem jeweiligen Schlitten 98 um eine in Anlagenlängsrichtung gesehen quer und horizontal verlaufende Achse möglich.A circular segment-shaped recess 106 is made in the upper edges of the two slides 98, in each of which a complementary bearing section 108 of a bearing element 110 is mounted. Rolling or sliding bearings can be provided along the boundary surface of the segment 106 in the form of a circular segment, which facilitate the relative movement of the bearing section 108 of the bearing element 110 with respect to the recess 106 of the slide 98. This allows the two support elements 110 to move freely relative to the respective slide 98 about an axis running transversely and horizontally as seen in the longitudinal direction of the system.
Der obere Bereich eines jeden Auflagerelements 110 weist eine flache Auflagerplatte 112 und einen seitlichen, einen schrägen Einführabschnitt 114 aufweisenden Seitenabschnitt 116 auf. Der vertikale Abstand der Auflagerplatte 112 gegenüber dem Lagerabschnitt 108 eines jeden Auflagerelements 110 ist durch einen Elektromotor 118 auf in den Figuren nicht näher dargestellte Art und Weise einstellbar. Die Hauptlager 30 des Fahrwegelements 32 liegen auf den Auflagerplatten 112 der beiden Auflagerelemente 110 auf.The upper region of each support element 110 has a flat support plate 112 and a lateral side section 116 having an inclined insertion section 114. The vertical distance of the platen 112 opposite the bearing section 108 of each bearing element 110 can be adjusted by an electric motor 118 in a manner not shown in the figures. The main bearings 30 of the guideway element 32 rest on the bearing plates 112 of the two bearing elements 110.
In Figur 2 ist ferner eine Datenerfassungs- und Steuereinheit 120 dargestellt, welche die verschiedenen Elektromotoren ansteuert und Signale von Stellungssensoren 122, 124, 126, 128, 130 und 132 bei den Elektromotoren sowie von Kraftaufnehmern 134 und 136 erhält, welche die Auflager- kräfte an den beiden Auflagerelementen 110 erfassen.FIG. 2 also shows a data acquisition and control unit 120 which controls the various electric motors and receives signals from position sensors 122, 124, 126, 128, 130 and 132 for the electric motors and from force transducers 134 and 136 which apply the support forces capture the two support elements 110.
Nun werden die Spann- und Dämpfvorrichtungen 16 unter Be- zugnahme auf die Figuren 4 und 5 im Detail erläutert, wobei funktional zur oben beschriebenen Hauptlager-Aufnahmevorrichtung identische Teile im allgemeinen die gleichen Bezugszeichen tragen:The tensioning and damping devices 16 are now explained in detail with reference to FIGS. 4 and 5, parts which are functionally identical to the main bearing receiving device described above generally bearing the same reference numerals:
Jede Spann- und Dämpfvorrichtung 16 umfaßt ein als auf den Schienen 18 verfahrbarer Wagen ausgebildetes Basiselement 20 mit vier Rädern 34. Dieser Wagen 20 wird von einem in den Figuren nicht sichtbaren Elektromotor angetrieben. In einer mittigen Ausnehmung 142 des Wagens 20 sind quer zur Anlagenlängsrichtung laufende im wesentlichen horizontale Schienen 52 und 54 angeordnet. Auf diesen ist ein als Schlitten ausgebildetes Zwischenelement 22 über Führungsstücke 148 verschieblich gelagert. Auch das Zwischenelement 22 ist von einem in den Figuren nicht sichtbaren Elektromotor bewegbar.Each tensioning and damping device 16 comprises a base element 20, designed as a carriage which can be moved on the rails 18, with four wheels 34. This carriage 20 is driven by an electric motor which is not visible in the figures. In a central recess 142 of the carriage 20 running essentially horizontal rails 52 and 54 are arranged transversely to the longitudinal direction of the system. An intermediate element 22 in the form of a slide is slidably mounted thereon via guide pieces 148. The intermediate element 22 can also be moved by an electric motor that is not visible in the figures.
Der Zwischenelement 22 hat nach oben offene wannenför ige Gestalt mit einer Bodenplatte 150. An diese sind vier in einer sich quer zur Anlagenlängsrichtung erstreckenden Li- nie angeordnete Gabellaschen 152 angeformt, welche sich in Anlagenlängsrichtung erstreckende Schwenkachsen vorgeben. Zwei dieser Lagerlaschen 152 sind in der Nähe des seitlichen Randes des Zwischenelements 22 angeordnet. In ihnen ist jeweils ein Anschlussabschnitt 154 eines Zylindergehäu- ses 156 eines Hydraulikzylinders 157 über einen Bolzen 158 schwenkbar gehalten. Die Hydraulikzylinder 157 umfassen jeweils Kolbenstangen 159 und bilden vertikale Stützelemente 24. Die oberen Enden der Kolbenstangen 159 tragen jeweils eine Auflagereinrichtung 28, die vorliegend als Lagerwinkel ausgebildet ist.The intermediate element 22 has an upwardly open trough-shaped shape with a base plate 150. Four fork brackets 152, which are arranged in a line extending transversely to the longitudinal direction of the system, are molded onto the latter Specify swivel axes extending in the longitudinal direction of the system. Two of these bearing brackets 152 are arranged in the vicinity of the lateral edge of the intermediate element 22. In each of them, a connection section 154 of a cylinder housing 156 of a hydraulic cylinder 157 is pivotably held via a bolt 158. The hydraulic cylinders 157 each comprise piston rods 159 and form vertical support elements 24. The upper ends of the piston rods 159 each carry a bearing device 28, which in the present case is designed as a bearing bracket.
An die oberen Enden der Zylindergehäuse 156 sind jeweils sich in Anlagenlängsrichtung erstreckende LagerzapfenAt the upper ends of the cylinder housings 156 there are bearing journals extending in the longitudinal direction of the system
160 angeformt. In die Lagerzapfen 160 greifen Gabellaschen 162 ein, welche wiederum jeweils an das distale Ende der160 molded. Fork tabs 162 engage in the journals 160, which in turn each reach the distal end of the
Kolbenstange 164 eines Hydraulikzylinders 166 anmontiert sind. Dessen Zylindergehäuse 168 weist wiederum einen Anschlußabschnitt 170 auf, welcher jeweils mit einer der inneren Lagerlaschen 152 auf der Bodenplatte 150 verbunden ist. Durch die Lagerlaschen 152 und die Anschlußabschnitte 154 und 170 sind die Hydraulikzylinder 157 und 166 kippsicher gehalten.Piston rod 164 of a hydraulic cylinder 166 are mounted. Whose cylinder housing 168 in turn has a connection section 170, which is each connected to one of the inner bearing brackets 152 on the base plate 150. The hydraulic cylinders 157 and 166 are held against tipping by the mounting brackets 152 and the connecting sections 154 and 170.
Durch die Hydraulikzylinder 166 kann der Winkel zwischen den Hydraulikzylindern 157 und der Ebene der BodenplatteThrough the hydraulic cylinders 166, the angle between the hydraulic cylinders 157 and the plane of the base plate can
150 und hierdurch die seitliche Position der Lagerwinkel150 and thereby the lateral position of the bearing bracket
161 eingestellt werden.161 can be set.
Die Hydraulikzylinder 157 und 166 sind mit einem Ven- tilblock 174 verbunden, der wiederum von der Steuer- und Datenerfassungseinrichtung 120 angesteuert wird. Diese erhält auch Signale von Stellungs- bzw. Wegsensoren 176, 178, 180 und 182, durch die der tatsächliche Hub der Hydraulikzylinder 157 und 166 angezeigt wird. Die Anlage 10 wird folgendermaßen betrieben:The hydraulic cylinders 157 and 166 are connected to a valve block 174, which in turn is controlled by the control and data acquisition device 120. This also receives signals from position or displacement sensors 176, 178, 180 and 182, by means of which the actual stroke of the hydraulic cylinders 157 and 166 is displayed. Plant 10 is operated as follows:
Zunächst zur Einstellung der Hauptlager-Aufnahmevorrichtungen 14 :First, to adjust the main bearing receptacles 14:
Die in einem Speicher der Steuer- und Datenerfassungseinrichtung 120 abgelegten individuellen Einstelldaten werden für jede der drei Hauptlager-Aufnahmevorrichtungen 14 der Anlage 10 für das individuelle herzustellende Fahr- egelement 32 abgerufen. Dann werden von der Steuer- und Datenerfassungseinrichtung 120 die elektrischen Stellantriebe 64 der vertikalen Stützelemente 24 angesteuert, so daß sich diese vertikal verstellen und das obere Zwischenelement 26 und die Auflagereinrichtung 28 in die ge- wünschte vertikale Position verfahren. Dabei wird durch das Zwangs-Synchronisiergetriebe 68 sichergestellt, daß der Hub der vertikalen Stützelemente 24 gleich ist, das obere Zwischenelement 26 also in jeder vertikalen Lage parallel zum unteren Zwischenelement 22 ausgerichtet ist. Von der Steu- er- und Datenerfassungseinrichtung 120 werden ferner dieThe individual setting data stored in a memory of the control and data acquisition device 120 are called up for each of the three main bearing receiving devices 14 of the system 10 for the individual driving element 32 to be produced. Then the control and data acquisition device 120 controls the electric actuators 64 of the vertical support elements 24, so that they adjust vertically and move the upper intermediate element 26 and the support device 28 into the desired vertical position. The forced synchronizing gear 68 ensures that the stroke of the vertical support elements 24 is the same, that is to say the upper intermediate element 26 is aligned parallel to the lower intermediate element 22 in every vertical position. From the control and data acquisition device 120, the
Elektromotoren 88 der Hauptlager-Aufnahmevorrichtungen 14 so angesteuert, daß sich die Grundplatte 82 der jeweiligen Auflagereinrichtungen 28 in die gewünschte Position um die durch den Lagerbolzen 86 vorgegebene vertikale Achse ver- schwenkt.Electric motors 88 of the main bearing receiving devices 14 are controlled such that the base plate 82 of the respective bearing devices 28 pivots into the desired position about the vertical axis predetermined by the bearing pin 86.
In gleicher Weise werden auch die Elektromotoren 100 der jeweiligen Hauptlager-Aufnahmevorrichtungen 14 so angesteuert, daß der Abstand zwischen den Auflagerelementen 110 der jeweiligen Hauptlager-Aufnahmevorrichtung 14 dem individuellen Hauptlager 30 des jeweiligen Fahrwegelements 32 entspricht.In the same way, the electric motors 100 of the respective main bearing receiving devices 14 are controlled so that the distance between the bearing elements 110 of the respective main bearing receiving device 14 corresponds to the individual main bearing 30 of the respective track element 32.
Eine Überprüfung der tatsächlichen Einstellungen der ver- schiedenen elektrischen Stellelemente ist durch die Wegsen- soren 122 bis 132 möglich, welche die aktuellen Stellungen der Stellelemente der Steuer- und Datenerfassungseinrich- tung 120 anzeigen. Dies ist für die Erzielung der gewünschten hohen Fertigungsgenauigkeit und auf Grund der Anforde- rungen der Qualitätssicherung besonders hilfreich.A check of the actual settings of the various electrical control elements is possible through the sensors 122 to 132 possible, which display the current positions of the actuating elements of the control and data acquisition device 120. This is particularly helpful for achieving the desired high level of manufacturing accuracy and due to the requirements of quality assurance.
Nach den erfolgten Einstellungen wird das dieser Einstellung entsprechende Fahrwegelement 32 von oben so abgesenkt, daß die Hauptlager 30 auf den Auflagerplatten 112 der Auf- lagerelemente 110 der drei Hauptlager-Aufnahmevorrichtungen 14 der Anlage 10 zum Liegen kommen.After the settings have been made, the travel path element 32 corresponding to this setting is lowered from above such that the main bearings 30 come to rest on the bearing plates 112 of the bearing elements 110 of the three main bearing receiving devices 14 of the installation 10.
Von den Kraftaufnehmern 134 und 136 werden die Auflager- lasten eines jeden Auflagerelements 110 individuell be- stimmt. Von der Steuer- und Datenerfassungseinrichtung 120 werden dann die Elektromotoren 118 eines jeden Auf- lagerelements 110 so angesteuert und hierdurch die Höhe der Auflagerplatten 112 der jeweiligen Auflagerelemente 110 so feinjustiert, daß die gewünschte Verteilung der Auflagerkräfte vorliegt.The support loads of each support element 110 are individually determined by the force transducers 134 and 136. The electric motors 118 of each support element 110 are then controlled by the control and data acquisition device 120, and the height of the support plates 112 of the respective support elements 110 is thereby finely adjusted so that the desired distribution of the support forces is present.
Dann wird der Ventilblock 174 der Steuer- und Datenerfassungseinrichtung 120 so angesteuert, daß die Hydraulikzylinder 157 und 166 der insgesamt acht Spann- und Dämpfvor- richtungen 16 in die dem Verlauf des individuellen Fahrwegelements 32 entsprechende Position bewegt werden, in denen die jeweiligen Lagerwinkel 161 am Basiskörper 172 des Fahrwegelements 32 angreifen. Auf diese Weise wird der zwischen zwei Hauptlager-Aufnahmevorrichtungen 14 liegende Abschnitt des Fahrwegelements 32 zusätzlich gestützt. Dies hat denThen the valve block 174 of the control and data acquisition device 120 is actuated such that the hydraulic cylinders 157 and 166 of the total of eight tensioning and damping devices 16 are moved into the position corresponding to the course of the individual guideway element 32, in which the respective bearing angles 161 at Attack base body 172 of guideway element 32. In this way, the section of the guideway element 32 lying between two main bearing receiving devices 14 is additionally supported. This has the
Vorteil, daß durch die Bearbeitung des vormontierten Fahrwegelements 32 auftretende Schwingungen des Fahrwegelements 32 gedämpft oder gegebenenfalls ganz unterdrückt werden, wodurch die Herstellgenauigkeit erhöht wird. In einem nicht dargestellten Ausführungsbeispiel erstrecken sich die Schienen 18 durch verschiedene Bearbeitungsstationen hindurch, so daß der aus den drei Hauptlager-Aufnahmevorrichtungen 14, den acht Spann- und DämpfVorrichtungen 16 und dem Fahrwegelement 32 gebildete "Zug" als Ganzes zwischen Bearbeitungsstationen bzw. Rüststationen hin und her gefahren werden kann.Advantage that vibrations of the guideway element 32 occurring due to the processing of the preassembled guideway element 32 are damped or, if necessary, completely suppressed, which increases the manufacturing accuracy. In an embodiment not shown, the rails 18 extend through different processing stations, so that the "train" formed from the three main bearing receiving devices 14, the eight tensioning and damping devices 16 and the guideway element 32 as a whole goes back and forth between processing stations or set-up stations can be driven here.
Die geschilderten Einstellungen können für jede der Hauptlager-Aufnahmevorrichtungen 14 und Spann- und Dampfvorrichtungen 16 individuell vorgenommen werden, so daß ein Fahrwegelement 32 mit einer bestimmten Kurvenkrümmung hergestellt werden bzw. bearbeitet werden kann.The described settings can be made individually for each of the main bearing receiving devices 14 and tensioning and steaming devices 16, so that a guideway element 32 with a specific curve curvature can be produced or processed.
Es versteht sich, daß anstelle elektrischer oder hydraulischer Stellelemente auch pneumatische oder manuelle Stelleinrichtungen verwendet werden können.It goes without saying that pneumatic or manual actuating devices can also be used instead of electrical or hydraulic actuating elements.
Die beschriebene Anlage kann außer zu der erwähnten mechanischen Bearbeitung des Fahrwegelements auch zur dessen Endvermessung eingesetzt werden.In addition to the mechanical processing of the guideway element mentioned, the system described can also be used for its final measurement.
Die von den verschiedenen Stellelementen eingenommene Position kann den Verzug, der sich bei der Bearbeitung des Fahrwegelements ergibt, antizipierend berücksichtigen, sodaß der Verzug automatisch kompensiert wird. The position taken up by the various adjusting elements can anticipate the delay that arises when processing the guideway element, so that the delay is automatically compensated for.
