Description

Die Erfindung betrifft eine Vorrichtung zur Erneuerung von Aufnahmemitteln für Gleisbefestigungsmaterial an Eisenbahnschwellen.The invention relates to a device for renewing receiving means for track fastening material on railway sleepers.

Bei Bau und Betrieb von Gleisanlagen für den Eisenbahnverkehr hat sich in Europa die Verwendung von Stahlbetonschwellen auf breiter Front durchgesetzt. Die Verwendung von Stahl- und Holzschwellen findet bei der Deutschen Bahn AG nur noch in einem eng begrenzten und durch technische Spezialfälle (z.B. Weichenschwellen oder Bereiche mit speziellen Anforderungen an eine geringe Bauhöhe des Gleisoberbaus) definierten Rahmen statt. Unter der Voraussetzung einer betontechnologisch ordnungsgemässen Fertigung erreichen Stahlbetonschwellen sehr hohe Liegezeiten und sind extrem belastbar. Das für die Lagefixierung der Schienen erforderliche Befestigungsmaterial (Rippenplatten) wird mittels Schraubverbindungen mit der Schwelle verbunden. Hierfür sind in der Stahlbetonschwelle Bohrungen mit eingelagerten Dübeln zur Aufnahme der Befestigungsschrauben vorhanden. Diese Dübel jedoch unterliegen einem belastungsabhängigen Verschleiss und haben eine geringere Standzeit als die eigentliche Stahlbetonschwelle. Aus dieser Problematik resultiert die Notwendigkeit, die Stahlbetonschwellen durch Erneuerung der Dübel aufzuarbeiten.In the construction and operation of railway track systems, the use of reinforced concrete sleepers has become widespread in Europe. At Deutsche Bahn AG, the use of steel and wooden sleepers only takes place in a narrowly defined framework defined by special technical cases (for example, sleepers or areas with special requirements for a low structural height of the track superstructure). Under the condition of a technologically correct production of concrete reinforced concrete sleepers reach very high lay times and are extremely resilient. The fastening material (ribbed plates) required for fixing the position of the rails is connected to the sleeper by means of screw connections. For this purpose, holes are available in the reinforced concrete sleeper with embedded dowels for receiving the mounting screws. However, these anchors are subject to a load-dependent wear and have a shorter life than the actual reinforced concrete threshold. This problem results in the need to work up the reinforced concrete sleepers by renewing the dowels.

So sind beispielsweise aus dem Stand der Technik transportable Schwellenschraubund Bohrmaschinen (sogenannter "Schraubpflug") bekannt, welche mit Laufrädern versehen sind und beim Arbeitseinsatz im verlegten Gleis von Schwelle zu Schwelle verschoben werden (Quelle: z.B. Lieferprogramme der Fa. Cemafer oder Fa. Robel). Hierbei werden zunächst die Befestigungsschraube aus der Schwelle ausgedreht und anschliessend der verschlissene Dübel mittels Dreh- und / oder Zerspanungswerkzeugen aus der Schwelle entfernt. Über eine Parallelogrammführung wird bei diesen Schraubpflügen sichergestellt, dass die Bohr- und Schraubspindel dieses Werkzeuges jeweils in vertikaler Ausrichtung an der Schwelle ansetzen. Dieses Verfahren ist weit verbreitet, jedoch kann es nur während Betriebspausen im Gleis zum Einsatz kommen. Zudem weist es auf Grund des eher niedrigen Mechanisierungsgrades ein geringe Produktivität auf. Beide Faktoren führen dazu, dass diese Vorrichtung bzw. dieses Verfahren nur bei einer Bearbeitung kleiner Losgrössen oder der Einzelfehlerbeseitigung wirtschaftlich vertretbar ist.
Weiterentwicklungen dieses technischen Ansatzes hatten bislang stets zum Ziel, manuelle Prozessbestandteile zu mechanisieren und damit eine höhere Produktivität innerhalb des vorgegebenen zeitlichen Rahmens für die im Gleis stattfindende Arbeitstätigkeit (Sperrpause) zu erzielen. So lehrt beispielsweise DE 20 05 111 einen gleisfahrbaren Tragrahmen mit einem um eine vertikale verschwenkbaren Träger für Bearbeitungswerkzeuge, bei dem mittels einer Zwangsführung das Aufsuchen des Dübels und das Zentrieren des Werkzeuges beschleunigt werden soll. In ähnlicher Weise offenbart US 4 522 127 eine selbstfahrende Vorrichtung für das taktweise Ausbohren bzw. Dübeln von Schraubenlöchern, welche sogar noch zusätzlich im Betriebsgleis verlegte Hilfsschienen erfordert. Dies ist mit den Betriebsbedingungen in Mitteleuropa jedoch gänzlich unvereinbar. Noch einen Schritt weiter in dieselbe Richtung geht AT 358 086, welche den Fachmann gar die Verwendung einer hochmechanisierten und vollautomatischen Gleisbaumaschine lehrt, welche beim Befahren des Arbeitsgleises die Schienenbefestigungen löst, die nunmehr losen Schienen aufnimmt, anhebt und auseinander spreizt sowie in der solchermassen erwirkten Arbeitszone Bearbeitungswerkzeuge - z.B. für das Einbringen von Dübeln in die Schraublöcher - zum Einsatz bringt. Grundsätzlich ändert sich an der hier verfolgten technologischen Linie nichts daran, dass diese Vorrichtungen bzw. Verfahren uanbhängig von ihrer jeweiligen Produktivität auf einen Einsatz im Betriebsgleis hin ausgerichtet sind und damit zwangsläufig Sperrpausen benötigen.
Zur Überwindung der damit einhergehenden Probleme und zur Erzielung wirtschaftlicher Vorteile durch eine verbesserte Auslastung des für die Schraubloch-Sanierung erforderlichen Maschinenparks hat es sich bei grösseren Losen etabliert, die erneuerungsbedürftigen Schwellen z.B. im Rahmen eines Gleisumbaus komplett gegen neue oder erneuerte Schwellen auszutauschen und die derart gewonnenen Schwellen einer zentralisierten Aufarbeitungsstelle mit ortsfest installierter Maschinerie (z.B. in zentralen Bauhöfen) zuzuführen. Dort werden die Schwellen auf ein Förderband aufgelegt und durchlaufen die für den Dübelaustausch erforderlichen Arbeitsstationen. Dieses Verfahren wiederum erfordert hinsichtlich der notwendigen Transportvorgänge zu / von den zentralen Aufarbeitungsstellen sowie Zwischenlagerplätzen hohe Aufwendungen für die logistische Koordination der Transporte, für die kaptialintensiven Transportfahrzeuge sowie für die Bewirtschaftung und Disposition der Zwischenlager.
DE 203 06 701 beschreibt schliesslich eine gleisverfahrbare Vorrichtung, welche die ausgebauten Schwellen am Bearbeitungsort aufnimmt und diese einer Sanierung unterzieht. Aber auch dieser Ansatz vermag nicht die bereits bekannten Nachteile in Form von erforderlichen Sperrpausen und hoher Kapitalbindung der eingesetzten Maschinen zu überwinden.Thus, for example, known from the prior art transportable Schwellenschraubund drills (so-called "Schraubpflug"), which are provided with wheels and are moved during operation in the laid track from threshold to threshold (Source: eg delivery programs of the Fa. Cemafer or Fa. Robel) , Here, first the fastening screw are turned out of the threshold and then removed the worn dowels by means of turning and / or cutting tools from the threshold. By means of a parallelogram guide, it is ensured in these screw plows that the drilling and screwing spindle of this tool are each set in vertical alignment at the threshold. This method is widely used, but it can only be used during breaks in the track. In addition, it has a low productivity due to the rather low degree of mechanization. Both factors mean that this device or this method is economically justifiable only when processing small batch sizes or the individual error removal.
Further developments of this technical approach have up to now always been aimed at mechanizing manual process components and thus achieving higher productivity within the given timeframe for work taking place on the track (lock-up break). For example, DE 20 05 111 teaches a track-mounted vehicle Support frame with a vertical pivotable about a carrier for processing tools in which by means of a positive guide, the prospecting of the dowel and the centering of the tool to be accelerated. Similarly, US 4 522 127 discloses a self-propelled device for the intermittent drilling of screw holes, which even requires additional auxiliary rails laid in the operating track. However, this is completely incompatible with the operating conditions in Central Europe. AT 358 086 goes one step further in the same direction, which even teaches the skilled person the use of a highly mechanized and fully automatic track-laying machine which solves the rail fastenings when driving on the working track, which now picks up loose rails, raises them and spreads them apart and in the working zone thus obtained Processing tools - eg for the introduction of dowels in the screw holes - brings to use. In principle, the technological line pursued here does not change the fact that these devices and / or processes are oriented, irrespective of their respective productivity, to use in the operating track and thus inevitably require blocking pauses.
In order to overcome the associated problems and to achieve economic advantages through improved utilization of the required for the screw hole rehabilitation machinery, it has become established in larger lots to replace the need for renewal thresholds, for example as part of a track renewal completely new or renewed thresholds and thus won To supply sleepers to a centralized processing station with stationary installed machinery (eg in central construction yards). There, the sleepers are placed on a conveyor belt and go through the necessary work stations for the dowel replacement. This method, in turn, requires high costs for the logistical coordination of the transports, for the capital intensive transport vehicles as well as for the management and disposition of the interim storage facilities with regard to the necessary transport processes to / from the central processing stations and intermediate storage areas.
Finally, DE 203 06 701 describes a track-movable device which picks up the removed sleepers at the processing location and subjects them to remediation. But even this approach can not overcome the already known disadvantages in the form of required lock pauses and high capital commitment of the machines used.

Der Erfindung liegt deshalb die Aufgabe zugrunde, eine Vorrichtung zur Erneuerung von Aufnahmemitteln für Gleisbefestigungsmaterial an Eisenbahnschwellen bereitzustellen, bei der auf eine Gleisbelegung zur Durchführung der Dübelerneuerung und zugleich auf logistisch aufwendige und kostenintensive Transportvorgänge verzichtet werden kann. Ganz besonders ist ein Verzicht auf hochspezialisierte und kapitalintensive Maschinentechnologien anzustreben. Es ist eine Lösung erforderlich, die eine kostengünstige Durchführung des Gewerkes "Dübelerneuerung" und damit ein wettbewerbsfähiges Anbieten parallel zu grösseren Gleis-Umbau- bzw. Erneurungsvorhaben ermöglicht.The invention is therefore based on the object of providing a device for renewing receiving means for track fastening material on railway sleepers, in which can be dispensed with a track occupancy to carry out the anchor renewal and at the same time logistically complex and costly transport operations. In particular, a renunciation of highly specialized and capital-intensive machine technologies should be striven for. A solution is needed that enables a low-cost implementation of the "dowel renewal" trade and thus a competitive offering in parallel with major track renewal or renovation projects.

Diese Aufgabe wird in Verbindung mit dem Oberbegriff des Patentanspruches 1 erfindungsgemäss dadurch gelöst, dass die Vorrichtung aus

  • einer Auflagervorrichtung zur Aufnahme der zu bearbeitenden Schwellen,
  • jeweils einer zur Längsachse der Auflagervorrichtung parallelen Fahrschiene entlang beider äusserer Längsseiten der Auflagervorrichtung, wobei beide Fahrschienen um mindestens das Längenmass der längsten zu bearbeitenden Gleisschwelle zueinander beabstandet sind,
  • mindestens einer auf mindestens einer der beiden Fahrschienen längsverfahrbaren und von der Fahrschiene abnehmbaren Vorrichtung zum Lösen und Entfernen von mit der Schwelle lösbar verbundenem Gleisbefestigungsmaterial,
  • mindestens einer auf mindestens einer der beiden Fahrschienen längsverfahrbaren und von der Fahrschiene abnehmbaren Vorrichtung zum Entfernen von mit der Schwelle nicht-lösbar verbundenen Dübeln,
  • mindestens einer auf mindestens einer der beiden Fahrschienen längsverfahrbaren und von der Fahrschiene abnehmbaren Vorrichtung zum Einbringen neuer Dübel sowie zum Anbringen und Befestigen von mit der Schwelle lösbar verbindbarem Gleisbefestigungsmaterial
aufgebaut ist. Dadurch wird ein modularer Aufbau einer Anlage zur Schwellenbearbeitung bzw. Dübelsanierung geschaffen, bei der die Schwellen unter Wegfall aufwendiger Transportvorgänge noch in unmittelbarer räumlicher Nähe zur Baustelle gelagert und anschliessend bearbeitet werden können. Der Aufbau dieser Anlage aus leicht zueinander fügbaren bzw. unkompliziert wieder voneinander trennbaren Modulbaugruppen ermöglicht ein problemloses Montieren bzw. Demontieren der Anlage, sodass diese Tätigkeit von dem auf der Baustelle ohnehin anwesenden Personal ohne grössere Anlern-Aufwendungen vorgenommen werden kann. Dies unterstützt in wirkungsvoller Weise einen flexiblen Personaleinsatz.This object is achieved in conjunction with the preamble of claim 1 according to the invention characterized in that the device
  • a support device for receiving the sleepers to be processed,
  • in each case a travel rail parallel to the longitudinal axis of the support device, along both outer longitudinal sides of the support device, wherein both travel rails are spaced apart from one another by at least the length dimension of the longest track sill to be processed,
  • at least one longitudinally movable on at least one of the two rails and removable from the running rail device for releasing and removing detachably connected to the threshold track fastening material,
  • at least one longitudinally movable on at least one of the two rails and removable from the running rail device for removing non-detachably connected to the threshold dowels,
  • at least one on at least one of the two rails longitudinally movable and removable from the running rail device for introducing new dowels and for attaching and attaching of the threshold detachably connectable track fastening material
is constructed. As a result, a modular structure of a system for threshold processing or anchor remediation is created, in which the thresholds can be stored in the immediate vicinity of the construction site, eliminating complex transport processes and subsequently processed. The construction of this system of easily accessible to each other or easily separable module assemblies allows easy assembly and disassembly of the system so that this activity can be made by the staff present on site anyway without major Anlern-expenses. This effectively supports a flexible workforce.

Somit kann diese Anlage auch kurzfristig zu wechselnden örtlichen Aufkommensschwerpunkten disponiert werden und ohne grössere Aufrüstmassnahmen in Betrieb genommen werden.Thus, this plant can also be arranged at short notice to changing local sources and be put into operation without major upgrading measures.

Dies wird wirkungsvoll dadurch unterstützt, dass die Auflagervorrichtung als eine aus Stahlprofilen gefügte Rahmenkonstruktion ausgeführt ist, die über Vorrichtungen zur Aufnahme von Hebegeschirren und / oder zur Aufnahme des Schwenkarmes eines Abrollkippers verfügt. In Verbindung mit form- und / oder kraftschlüssigen Verbindungsvorrichtungen zur modularen Erweiterung in Längsrichtung um weitere erfindungsgemässe Auflagervorrichtungen sowie bodenseitige Nivelliervorrichtungen zum Ausrichten in der horizontalen Ebene ist eine schnelle Montage bzw. Demontage mit den üblichen baustellenseitig verfügbaren Hilfsmitteln möglich. Es versteht sich von selbst, dass der Aufbauort idealerweise über einen hinreichend festen und ebenen Untergrund verfügen sollte. Dies ist im Nahbereich von Eisenbahnstrecken in Form von Ladestrassen oder sonstigen befestigten Zu- oder Randwegen oftmals gegeben. Im Bedarfsfall ist ein solcher Stellplatz auch durch Abschieben des Mutterbodens und Herstellung eines temporären Kiesplanum kurzfristig herrichtbar.This is effectively assisted by the fact that the support device is designed as a frame structure made of steel profiles, which has devices for receiving lifting harnesses and / or for receiving the swivel arm of a roll-off tipper. In conjunction with positive and / or non-positive connection devices for modular extension in the longitudinal direction to further inventive support devices and bottom leveling devices for aligning in the horizontal plane fast assembly or disassembly is possible with the usual tools available on site. It goes without saying that the construction site should ideally have a sufficiently firm and even surface. This is often the case in the vicinity of railway lines in the form of loading lanes or other fixed access or edge paths. If necessary, such a parking space can be prepared in the short term by pushing off the topsoil and producing a temporary gravel planum.

Eine Abwandlung des Erfindungsgedankens sieht vor, dass die Auflagervorrichtung in Form eines Schwellenbettes ausgeführt ist, welches aus ohne Zwischenabstand nebeneinander sowie in einer näherungsweise horizontalen Ebene angeordneten Schwellen besteht. Dies stellt eine einfache, aber zweckmässige Variante dar, wenn eine als starres Bauteil ausgeführte Auflagervorrichtung nicht zugeführt werden kann oder anderweitig nicht verfügbar ist.A modification of the inventive concept provides that the support device is designed in the form of a threshold bed, which consists of without intermediate space next to each other and arranged in an approximately horizontal plane thresholds. This represents a simple but expedient variant, if a bearing device designed as a rigid component can not be supplied or is otherwise unavailable.

Es ist besonders zweckmässig, wenn die Vorrichtung zum Lösen und Entfernen von mit der Schwelle lösbar verbundenem Gleisbefestigungsmaterial aus mindestens einem auf den Fahrschienen verfahrbaren und die zu bearbeitenden Gleisschwellen rechtwinklig zur Längsachse der Fahrschienen überspannenden Portal sowie mindestens einer auf diesem Portal um eine zur Längsachse des Portals parallele Achse kippbar sowie um eine zur durch die Auflagervorrichtung aufgespannten näherungsweise horizontalen Ebene vertikalen Achse kippbar gelagerten Schwellen-Schraubmaschine besteht. Auf diese Weise kann die Anlage besonders kostengünstig mit in der Baustellenpraxis ohnehin vorhandenen bzw. relativ kostengünstig einkaufbaren handelsüblichen Schwellen-Schraubmaschinen ausgerüstet werden. Deren bewegliche Lagerung um die genannten beiden Raumachsen stellt sicher, dass die zu bearbeitenden Schraubenlöcher auch bei nicht exakt rechtwinkliger bzw. lagegenauer Ausrichtung der zu bearbeitenden Schwellen durch das Bedienpersonal angesteuert werden können. Zusätzlich ist von Vorteil, dass der Umgang mit diesem Standard-Werkzeug dem Baustellen-Personal vertraut ist und deshalb keine Anlern-Aufwendungen anfallen. Die gesamte Anlage kann in flexibler Weise von wechselndem Personal aufgebaut und bedient werden. Idealerweise weist das Portal zwei Schraubpflüge auf, und zwar links bzw. rechts jeweils oberhalb des Bereiches der Schraublöcher für die Befestigungsmittel der linken bzw. rechten Schiene. Bei einer vereinfachten Ausführung kann ein längs des Portals querverschiebbarer Schraubpflug vorgesehen werden, jedoch ist dieses Querverschieben eine mühsame Bedienhandlung, die die Produktivität der Anlage erheblich mindert.It is particularly useful if the device for releasing and removing detachably connected to the threshold track fastening material from at least one movable on the rails and to be processed sleepers at right angles to the longitudinal axis of the rails spanning portal and at least one on this portal to a longitudinal axis of the portal tiltable parallel axis and a tiltable mounted about the support device formed by the support device approximately horizontal plane vertical axis sleeper mounted screwdriver. In this way, the system can be equipped particularly cost with existing in construction site practice anyway or relatively inexpensively purchasable commercial threshold screwdrivers. Their movable mounting around the two spatial axes ensures that the screw holes to be machined can be controlled by the operator even when not exactly right-angled or position-accurate alignment of the thresholds to be processed. In addition, it is advantageous that the handling of this standard tool is familiar to the site personnel and therefore no Anlern-expenses incurred. The entire system can be set up and operated in a flexible manner by changing personnel. Ideally, the portal has two Schraubpflüge, namely left or right respectively above the range of screw holes for the fasteners of the left and right rail. In a simplified embodiment, a transversely displaceable Schraubpflug can be provided along the portal, however, this transverse displacement is a tedious operation that significantly reduces the productivity of the system.

Es ist sinnvoll, die Vorrichtung zum Einbringen neuer Dübel in analoger Weise hierzu auszustatten.It makes sense to equip the device for introducing new dowels in an analogous manner to this.

In Ergänzung hierzu ist es sinnvoll, wenn die Vorrichtung zum Entfernen der Dübel als eine auf den Führungsschienen verfahrbare Rahmenkonstruktion, in die eine der Anzahl der zu bearbeitenden Dübelbohrungen einer Schwelle korrespondierende Anzahl von Werkzeugträgern mit an sich bekannten Vorrichtungen zum Vorschneiden, Ausdrücken und / oder Ausspülen der verschlissenen Dübel integriert ist, aufgebaut ist. Zweckmässigerweise weist diese Vorrichtung jeweils eine die Schwellen im Bereich ihrer beidseitig über das Auflagegestell hinaus auskragenden Teile unterfassende und dem durch Einwirken der Werkzeuge zum Vorschneiden, Ausdrücken und / oder Ausspülen ausgeübten Kippmoment entgegenwirkende Abstützvorrichtung auf. Ebenso ist es für den Arbeitsablauf hilfreich, wenn eine in analoger Weise angeordnete Auffangvorrichtung zur Aufnahme der ausgestossenen Alt-Dübel vorhanden ist.In addition, it makes sense if the device for removing the dowel as a movable frame on the guide rail construction, in the one of the number of to be machined dowel holes of a threshold corresponding number of tool carriers with known devices for pre-cutting, expressing and / or rinsing the worn dowel is integrated, is constructed. Expediently, this device in each case has a supporting device which counteracts the thresholds in the region of its parts projecting beyond the support frame on both sides and counteracts the tilting moment exerted by the action of the tools for pre-cutting, expressing and / or rinsing. Likewise, it is helpful for the workflow, if a arranged in an analogous way catching device for receiving the ejected old dowels is present.

Der Erfindungsgedanke wird in nachfolgender Figur verdeutlicht. Es zeigt:

The idea of the invention is illustrated in the following figure. It shows:
FIG. 1
Section view of the device according to the invention; Section transverse to the longitudinal axis of the support device through the device for removing the worn dowels

Anhand dieser Figur lässt sich folgendes Ausführungsbeispiel nachvollziehen:Based on this figure, the following embodiment can be understood:

Im Rahmen einer Baumassnahme sollen die derzeit im Gleis eingebauten Stahlbetonschwellen einer Dübelsanierung unterzogen werden. Es wird zu diesem Zweck im näheren räumlichen Umfeld der Baustelle ein geeigneter hinreichend standfester und ebener Bearbeitungsplatz (4) hergerichtet. Auf diesem wird die mittels LKW-Abrollkipper angelieferte Aufnahmevorrichtung (1) abgesetzt und durch Auskeilen oder ähnliche Massnahmen nivelliert. Auf die beiderseits entlang der Aufnahmevorrichtung (1) verlegten und mindestens um das Längsmass der zu bearbeitenden Schwelle (2) beabstandeten Führungsschienen (Leerschienen) (3) werden drei längsverfahrbare, auf Laufrollen gelagerte Portale gesetzt.
Die zu sanierenden Schwellen (2) werden nach ihrem Ausbau aus dem Betriebsgleis mittels eines mit einer Traverse ausgestatteten Baggers auf die Auflagervorrichtung (1) aufgelegt, so dass die kopfseitigen Schwellenbereiche mit dem Kleineisen zur Schienenbefestigung jeweils über die Aufnahmevorrichtung (1) hinausragen. Ein vorauslaufendes Portal dient zum Ausbau des noch auf den Schwellen befindlichen Kleineisens (im wesentlichen Rippenplatten). Unmittelbar darauf folgt das zum Verfahren in Längsrichtung motorisch antreibbare mittlere Portal (7) zur Entfernung der Dübel. Dieses weist Ausdrückzylinder (8) zum Ausdrücken der in den Befestigungslöchern (13) der Schwelle (2) sitzenden Dübel auf. Die Feinausrichtung der Ausdrückzylinder (8) in der zur Schwellenoberläche horizontalen Arbeitsebene erfolgt manuell durch einen Bediener. Alternativ können in fachüblicher Weise die Dübel - je nach Konstruktionsweise der Schwelle (Bohrung (13) als Durchgangsloch oder Sackloch) - auch mittels am Portal (7) angebrachter zerspanender Arbeitsvorrichtungen und / oder Hochdruck-Spülvorrichtungen aus der Schwelle ausgetrieben bzw. entfernt werden. Ein nachlaufendes Portal dient zum Wiedereinbringen neuer Dübel (sog. "Sanierungsdübel"). Die vor- und nachlaufenden Portale sind weitgehend baugleich ausgeführt. Sie umfassen eine in geringer Höhe oberhalb der zu bearbeitenden Schwellen (2) verlaufende Quer-Traverse, auf welcher jeweils zwei Schwellen-Schraubmaschinen (sog. "Schraubpflug") montiert sind. Beide Schraubpflüge sind jeweils so angebracht, dass die linke bzw. rechte Reihe der Befestigungsbohrungen in deren Arbeitsbereich liegen. Die Schraubpflüge sind hierzu um eine zur Längsachse des Portals parallele Achse sowie um eine zur durch die Auflagervorrichtung (1) aufgespannte, näherungsweise horizontale Ebene vertikale Achse kippbar gelagert. Mittels der Schraubpflüge des vorauslaufenden Portals entfernt das Bedienpersonal das Kleineisen, speziell die Rippenplatten, von den Schwellen; mittels der Schraubpflüge des nachlaufenden Portals bringt das Bedienpersonal die neuen Schraubdübel in die Schwelle ein und befestigt erneut die Rippenplatten. Vorteilhafterweise können für diese Vorrichtungen altbrauchbare Schwellen-Schraubmaschinen eingesetzt werden.As part of a construction project, the reinforced concrete sleepers currently installed in the track are to undergo an anchor rehabilitation. It is for this purpose in the immediate vicinity of the site a suitable sufficiently stable and level Processing station (4) prepared. On this delivered by means of truck hookloader receiving device (1) is discontinued and leveled by wedging or similar measures. On the both sides along the receiving device (1) and laid at least by the Längsmass of the threshold to be processed (2) spaced guide rails (empty rails) (3) three longitudinally movable, mounted on rollers portals are set.
After their removal from the operating track, the sleepers (2) to be rehabilitated are placed on the support device (1) by means of an excavator equipped with a crossbeam, so that the head-end sleeper areas protrude beyond the receiving device (1) with the iron for rail fastening. A leading portal is used to remove the still on the threshold iron (essentially ribbed plates). Immediately thereafter followed by the process in the longitudinal direction motor driven central portal (7) for removing the dowels. This has ejection (8) for expressing the anchoring in the mounting holes (13) of the threshold (2) dowels. The fine alignment of the Ausdrückzylinder (8) in the working surface horizontal to the threshold surface is done manually by an operator. Alternatively, the dowels - depending on the design of the threshold (hole (13) as a through hole or blind hole) - also driven by means of portal (7) attached cutting work devices and / or high-pressure flushing devices from the threshold or removed in the usual way. A trailing portal serves to reintroduce new dowels (so-called "renovation dowels"). The leading and trailing portals are largely identical. They comprise a transverse cross-member extending at a slight height above the sleepers (2) to be machined, on each of which two sleeper screwdrivers (so-called "screw-type plow") are mounted. Both Schraubpflüge are each mounted so that the left and right row of mounting holes are in their working area. For this purpose, the screw plows are mounted so as to be tiltable about an axis parallel to the longitudinal axis of the portal as well as about an axis which is vertical about the vertical axis which is spanned by the support device (1). By means of the screw plows of the leading portal, the operator removes the iron, especially the ribbed plates, from the sleepers; By means of the screw plows of the trailing portal, the operator brings the new screw dowels in the threshold and fastened again the ribbed plates. Advantageously, old-use threshold screwdrivers can be used for these devices.
