Abstract

To construct a ballastless permanent way (27), concrete is mechanically shaped directly by means of a paver slipform (6). At the same time, a longitudinal reinforcement consisting of a plurality of longitudinal-reinforcement wires (19) is introduced into the concrete. Welded onto these longitudinal-reinforcement wires (19) at equal distances are transverse-reinforcement stirrups (20). For this purpose, welding tongues (21) are fixed to a running carriage (4) and individual transverse-reinforcement stirrups (20) can be supplied to them from a stirrup magazine (16). During the welding of the stirrups with the longitudinal-reinforcement wires (19), the running gear (4) is drawn out counter to the travelling direction (26) and subsequently moved into the starting position by a restoring cylinder (13). It is thus possible to continue the concrete placement even during the welding operation. <IMAGE>

Description

Die Erfindung betrifft einen Gleitschalungsfertiger nach dem Oberbegriff des Anspruchs 1.The invention relates to a slipform paver the preamble of claim 1.

Ein Gleitschalungsfertiger dieser Art ist bekannt und in der Zeitschrift "Schweizer Journal", April 1993, Seite 33 beschrieben. Mit diesem Fertiger wird gleichzeitig mit dem Einbringen des Betons eine leichte Längsarmierung maschinell in den Beton eingebracht. Die Längsarmierung besteht aus mehreren parallel von einer Drahtauslegevorrichtung dem Fertiger zugeführten Drähten. Die Vorteile eines mit diesem Fertiger erstelltem schotterlosen Gleisoberbaus sind eine hohe Tragfertigkeit, ein minimaler Unterhalt und eine rationelle Ausführbarkeit. Ein mit diesem Fertiger erstellter Gleisoberbau genügt für den Personenverkehr, jedoch nicht für den Güterverkehr, bei dem auf die Schienen seitlich starke Schlagkräfte einwirken. Um auch diese seitlichen Kräfte aufnehmen zu können, wurden in solchen Fällen Armierungskörbe in den Beton eingebracht. Diese Körbe bestehen aus einzelnen miteinander verschweissten Armierungskörben. Das Verschweissen dieser einzelnen Körbe bedingt einen hohen Arbeitsaufwand.A slipform paver of this type is known and in of the journal "Schweizer Journal", April 1993, page 33 described. With this paver, the Applying the concrete a slight longitudinal reinforcement mechanically placed in the concrete. The longitudinal reinforcement exists from several parallel from a wire laying device Wire fed to paver. The advantages of one with this Finished, ballastless track superstructure are one high carrying capacity, minimal maintenance and rational Feasibility. One created with this paver Track superstructure is sufficient for passenger transport, but not for freight transport, on the side of the rails strong impact. To also this side In such cases, reinforcement cages were able to absorb forces placed in the concrete. These baskets are made up from individual welded reinforcement baskets. The welding of these individual baskets requires a high level Workload.

In der DE-A-2 347 636 ist eine Vorrichtung offenbart, mit der ein schotterloser Oberbau erstellt werden kann. Auf einer fahrbaren Einrichtung ist ein Schweissgerät angebracht, mit dem Querarmierungsbügel automatisch mit Längsarmierungsdrähten verschweisst werden. Die so fertiggestellte Bewehrung wird in eine vorbereitete Schalung eingelegt und anschliessend wird Beton für den Oberbau eingebracht. Bei dieser Vorrichtung handelt es sich nicht um einen Gleitschalungsfertiger und entsprechend sind hier auch keine Gleitschalungsformen vorgesehen.DE-A-2 347 636 discloses a device with who can build a ballastless superstructure. On A mobile device is a welding machine attached, with the cross reinforcement bracket automatically Longitudinal reinforcement wires are welded. The so Completed reinforcement is prepared in a Formwork is inserted and then concrete for the Superstructure introduced. This device is are not a slipform paver and are appropriate no slipform forms are provided here either.

Der Erfindung liegt die Aufgabe zugrunde, einen Gleitschalungsfertiger der genannten Art zu schaffen, mit dem für den Güterverkehr geeignete Gleisoberbauten rationeller erstellt werden können. The invention has for its object a slipform paver of the kind mentioned with which suitable rail superstructures are rationally created for freight transport can be.

Die Erfindung ist bei einem gattungsgemässen Gleitschalungsfertiger gemäss Kennzeichen des Anspruchs 1 gelöst. Der erfindungsgemässe Gleitschalungsfertiger erlaubt eine kontinuierliche und damit sehr rationelle und leistungsfähige Herstellung eines Gleisoberbaus mit einem Armierungskorb. Im Gegensatz zu einem Armierungskorb, der aus einzelnen Körben durch Stumpfschweissen der Längsarmierungsdrähte hergestellt ist, weist der mit dem erfindungsgemässen Gleitschalungsfertiger erstellte Armierungskorb in den Längsarmierungsdrähten keine solche Schweissungen auf, die nach dem Einbau brechen können. Da das Schweissgerät an einem Laufwagen angebracht ist, ist ein Anhalten des Betoneinbaus während den Schweissungen nicht erforderlich. Die Erfindung ermöglicht infolgedessen eine weitgehend maschinelle Erstellung eines schotterlosen Oberbaus mit einem endlosen Armierungskorb. Da die Längsdrähte nicht geschweisst sind und der Einbau kontinuierlich erfolgt, ist ein mit dem erfindungsgemässen Gleitschalungsfertiger erstellter Gleisoberbau besonders gleichmässig und stabil und genügt insbesondere für den Güterverkehr. Vorteilhafte Weiterbildungen der Erfindung ergeben sich aus den abhängigen Patentansprüchen.The invention is in a generic slipform paver solved according to the characterizing part of claim 1. The slipform paver according to the invention allows one continuous and therefore very efficient and efficient Production of a track superstructure with a reinforcement cage. In contrast to a reinforcement cage made from individual baskets by butt welding the longitudinal reinforcement wires is produced, the one with the inventive Slipform paver created reinforcement basket in no such welds on the longitudinal reinforcement wires, that can break after installation. As the welding machine on a carriage is stopping the concrete installation not required during the welds. As a result, the invention enables a largely mechanical one Creation of a ballastless superstructure with one endless armouring basket. Because the longitudinal wires are not welded and the installation is continuous a created with the slipform paver according to the invention Track superstructure particularly even and stable and is particularly sufficient for freight transport. Advantageous further training the invention result from the dependent Claims.

Fig. 2
2 shows a front view of the slipform paver according to FIG. 1.

Ein Grundrahmen 1 ist höhenverstellbar an einem Raupenfahrwerk 2 angebracht und mit einer an sich bekannten Fertigergleitschalung 6 verbunden. Der Fertigergleitschalung 6 wird mit einer hier nicht gezeigten Fördervorrichtung Beton zugeführt, aus dem ein hier nur andeutungsweise gezeigter schotterloser Gleisoberbau 27 erstellt wird. Der Beton wird durch die Fertigergleitschalung 6 in die vorgesehene Form gebracht und gleichzeitig wird ein endloser Armierungskorb 25 in den Beton eingebracht. Dieser Korb 25 besteht aus Querarmierungsbügeln 20, die gleich ausgebildet sind und in gleichen Abständen mit beispielsweise sechs parallelen Längsdrähten 19 verschweisst sind. Diese Längsdrähte 19 werden ab einer hier nicht gezeigten Bobine einer an sich bekannten Drahtauslegevorrichtung einer Drahtaufnahme 17 zugeführt. Diese Drahtaufnahme 17 weist entsprechend der Anzahl Längsdrähte Durchgänge 28 auf, durch welche Drähte 19 hindurchgezogen sind. Die Drahtaufnahme 17 ist an einem Gestell 9 eines Laufwagens 4 angebracht. Dieser Laufwagen 4 ist mittels Rollen 7 an zwei fest mit einer Aufhängekonsole 3 verbundenen Führungen 8 in Gegenrichtung zur Fahrrichtung des Fahrwerkes 2 ausziehbar gelagert. In Fig. 1 ist die Fahrrichtung mit dem Pfeil 26 angegeben. Der Laufwagen 4 kann infolgedessen in Fig. 1 nach links ausgezogen werden. Mittels Rückholzylindern 13 kann der Laufwagen 4 von der ausgezogenen Lage in die in Fig. 1 gezeigte Ausgangslage zurückgebracht werden.A base frame 1 is adjustable in height on a crawler track 2 attached and with a known prefabricated slipform 6 connected. The paver slipform 6 is Concrete supplied with a conveyor device, not shown here, from which one is only hinted at here ballast track 27 is created. The concrete will through the paver slipform 6 into the intended shape brought and at the same time an endless reinforcement basket 25 placed in the concrete. This basket 25 consists of Cross reinforcement brackets 20 which are of the same design and in equal distances with, for example, six parallel ones Longitudinal wires 19 are welded. These longitudinal wires 19th from a Bobine not shown here become one in itself Known wire laying device of a wire receptacle 17 fed. This wire receptacle 17 points accordingly Number of longitudinal wires passages 28 through which wires 19 are pulled through. The wire receptacle 17 is on one Frame 9 of a carriage 4 attached. This carriage 4 is fixed with rollers 7 to two with a hanging bracket 3 connected guides 8 in the opposite direction to the direction of travel of the chassis 2 stored extendable. 1 is the Direction of travel indicated by arrow 26. The carriage 4 can therefore be extended to the left in Fig. 1. The carriage 4 can be moved from the extended position in the starting position shown in Fig. 1 be brought back.

Am Laufwagen 4 ist über der Drahtaufnahme 17 ein Bügelmagazin 16 befestigt, das gemäss Fig. 1 in Fahrrichtung geneigt nach vorne ragt und das durch eine Bedienungsperson 15 mit Bügeln 20 beschickt werden kann. Durch die geneigte Anordnung des Bügelmagazins 16 gleiten die Bügel 20 nach unten, bis zu einer Bügelübergabe 18. Mit dieser Uebergabe kann jeweils der unterste Bügel 20' gefasst und an die Schweisszangen 21 übergeben werden, die unmittelbar vor einer Bügeleinführungsplatte 10 angeordnet sind. Die Schweisszangen 21 sind mit einem ebenfalls am Laufwagen 4 angeordneten Schweisstransformator über Schweisszangenkontakte 22 und 23 verbunden. Die Anzahl Schweisszangen 21 entspricht der Anzahl Längsdrähte 19. Wie die Fig. 2 zeigt, ist jeweils über jedem Längsdraht 19 eine Schweisszange 21 angeordnet. Jeder an die Schweisszangen 21 übergebene Querarmierungsbügel 20" wird durch die Schweisszangen 21 an die Längsdrähte 19 und gegen einen Schweisszangenkontakt 23 angepresst. Mit den Schweisszangen 21 kann somit der Querarmierungsbügel 20" mit jedem Längsdraht 19 an den anliegenden Stellen verschweisst werden. Die Steuerung erfolgt über eine in einem Steuerungskasten 11 angeordneten Steuervorrichtung.On the carriage 4 is an ironing magazine over the wire receptacle 17 16 attached, which is inclined according to FIG. 1 in the direction of travel protrudes forward and by an operator 15 with Iron 20 can be loaded. Due to the inclined arrangement the bracket magazine 16, the bracket 20 slide down, up to a handover 18. With this handover the bottom bracket 20 'is gripped and attached to the welding guns 21 are passed immediately in front of a bracket insertion plate 10 are arranged. The welding guns 21 are also arranged on the carriage 4 Welding transformer via welding gun contacts 22 and 23 connected. The number of welding guns 21 corresponds to the number Longitudinal wires 19. As shown in FIG. 2, each is over a welding gun 21 is arranged in each longitudinal wire 19. Everyone transverse arm 20 "transferred to the welding guns 21" is by the welding guns 21 to the longitudinal wires 19 and pressed against a welding gun contact 23. With the The welding arm 21 can thus the cross arm 20 " welded to each adjacent wire 19 at the adjacent points will. It is controlled by one in one Control box 11 arranged control device.

Während eines solchen Schweissvorganges bleibt der Laufwagen 4 durch die Verbindung der Schweisszangen 21 mit dem Armierungskorb 5 bezüglich des Bauuntergrundes 14 stehen. Das Laufwerk 2 mit dem Grundrahmen 1 sowie die Fertigergleitschalung 6 werden jedoch während eines solchen Schweissvorganges in Richtung des Pfeiles 26 ohne Geschwindigkeitsänderung weiter bewegt. Der Laufwagen 4 wird während einer Schweissung in Gegenrichtung des Pfeiles 26 ausgezogen. Nach Beendigung einer Schweissung wird der Laufwagen durch die Rückholzylinder 13 wieder zurück in die Ausgangslage bewegt. Während diesen Bewegungen des Laufwagens 4 wird die Bügeleinführungsplatte 10 mitbewegt, wobei eine Oeffnung 23 einen Durchtritt der Längsdrähte 19 und der angeschweissten Querarmierungsbügels 20" ermöglicht.The carriage remains during such a welding process 4 by connecting the welding guns 21 to the Reinforcement basket 5 stand with respect to the building base 14. The drive 2 with the base frame 1 and the paver slipform 6 will, however, during such Welding process in the direction of arrow 26 without changing the speed moved on. The carriage 4 is during a weld pulled out in the opposite direction of arrow 26. After a welding process is finished, the carriage will through the log cylinder 13 back to the starting position emotional. During these movements of the carriage 4, the bow insertion plate 10 is also moved, one Opening 23 a passage of the longitudinal wires 19 and the welded Cross arm 20 "allows.

Infolge des hohen Stromverbauches solcher Schweissungen werden die einzelnen Punktschweissungen eines Bügels paarweise im Taktschrittverfahren durchgeführt. Die gesamte Schweisszeit für einen Bügel beträgt etwa 12 Sekunden. Vorzugsweise werden gleichzeitig zwei parallel nebeneinander verlaufende Armierungskörbe 25 erstellt. Entsprechend weist der Wagen 4, wie aus Fig. 2 ersichtlich, die zum Auslegen der Längsarmierungsdrähte 19 und zum Verschweissen der Querarmierungsbügel 20 erforderlichen Teile und Geräte paarweise nebeneinander auf.As a result of the high power consumption of such welds the individual spot welds of a bracket are made in pairs carried out in a step-by-step process. The whole Welding time for a bracket is about 12 seconds. Preferably become two in parallel side by side extending reinforcement cages 25 created. Correspondingly points the carriage 4, as can be seen in Fig. 2, for laying of the longitudinal reinforcement wires 19 and for welding the Cross arm 20 required parts and equipment in pairs next to each other.

Die Querarmierungsbügel 20 werden in gleichen Abständen von beispielsweise 15 cm mit den Längsdrähten 19 verschweisst. Damit diese Abstände eingehalten werden, erfolgt die Bügelübergabe an die Schweisszangen 21 über einen Steuerungsimpuls, der von einem auf dem Raupenfahrwerk 2 befestigten Drehimpulsgeber 29 ausgelöst wird. Der Drehimpulsgeber 29 weist beispielsweise ein Rad 30 auf, das an einer Raupenkette 31 des Fahrwerks 2 anliegt und sich mit diesem dreht. Eine bestimmte Fahrstrecke entspricht dann einer bestimmten Anzahl Impulse des Drehimpulsgebers 29. Die Auslösung der selbsttätigen Bügelübergabe kann jedoch auch durch einen anderen geeigneten Geber erfolgen.The cross arm 20 are at equal intervals from welded for example 15 cm to the longitudinal wires 19. So that these distances are maintained, the stirrup is handed over to the welding guns 21 via a control pulse, the one attached to the crawler track 2 Angular pulse generator 29 is triggered. The rotary pulse generator 29 For example, has a wheel 30 on a crawler belt 31 of the chassis 2 rests and rotates with it. A certain route then corresponds to a certain one Number of pulses from the rotary pulse encoder 29. The triggering of the automatic transfer of hangers can also be done by a other suitable encoders.

Nachfolgend wird der Arbeitsablauf kurz erläutert.The workflow is briefly explained below.

Von der Drahtauslegevorrichtung werden ab Bobine die Längsarmierungsdrähte 19, in diesem Fall zwölf Drähte, auf den Unterbau ausgelegt. Die ausgelegten Armierungsdrähte werden nun in die Drahtaufnahme 17 eingeführt und gelangen einzeln zu den, in diesem Fall zwölf Schweisszangen 21. Ueber Steuerungsimpulse werden aus dem Magazin 16 nun einzeln Querarmierungsbügel 20 mittels der Uebergabe 18 an die Schweisszangen 21 übergeben. Jeder Bügel wird im Taktschrittverfahren durch Punktschweissung mit den Längsdrähten 19 verschweisst. Während eines solchen Schweissvorganges werden die Schweisszangen 21 über den Laufwagen 4 ausgezogen und nach dem Schweissen mit den Pneumatikzylindern 13 in die Ausgangslage zurückgebracht. Der fertig geschweisste Armierungskorb 25 wird über eine Korbaufnahme 30, die ähnlich wie die Platte 10 ausgebildet ist, in die Fertigergleitschalung 6 eingeführt.From the bobbin, the longitudinal reinforcement wires are removed from the wire laying device 19, in this case twelve wires, on the Substructure designed. The laid reinforcement wires are now inserted into the wire receptacle 17 and arrive individually to the, in this case twelve welding guns 21 Control impulses are now generated individually from magazine 16 Cross arm 20 by means of the transfer 18 to the Hand over welding guns 21. Each bracket is clocked by spot welding with the longitudinal wires 19 welded. During such a welding process the welding guns 21 are pulled out over the carriage 4 and after welding with the pneumatic cylinders 13 brought back to the starting position. The welded one Reinforcement basket 25 is a basket holder 30, which is similar to the plate 10, in the Paving slipform 6 introduced.
