Description

Eisenbahnkran  Railway crane
Die vorliegende Erfindung betrifft einen Eisenbahnkran mit einem ersten Kranausleger an seinem einen Ende, einem zweiten Kranausleger an seinem anderen Ende und einer Transportaufnahme dazwischen, wobei der erste Kranausleger, der zweite Kranausleger und die Transportaufnahme jeweils auf einem Fahrgestell angeordnet sind, die gelenkig aneinandergekuppelt sind. The present invention relates to a railway crane with a first crane boom at one end thereof, a second crane boom at its other end and a transport receiver therebetween, the first crane boom, the second crane boom and the transport receptacle each being mounted on a chassis articulated to each other.
Eisenbahnkrane besitzen üblicherweise nur einen einzigen Kranausleger (Kranarm) . Für das Heben besonders schwerer Lasten wie Brückenteile, Lokomotiven od.dgl. werden manchmal zwei Ein- arm-Kräne eingesetzt, welche möglichst synchron verfahren und betätigt werden müssen, um die Einleitung gefährlicher Lateralkräfte in die Hebegeschirre zu vermeiden. Ein Transportieren der Last über längere Strecken ist mit zwei an den Enden der Last angreifenden Einarm-Kränen nur langsam möglich, da ein Aufbauen von gefährlichen Schwingungen unbedingt vermieden werden muss.  Railway cranes usually have only one crane jib (crane arm). For lifting particularly heavy loads such as bridge parts, locomotives or the like. sometimes two single-arm cranes are used, which must be moved and operated as synchronously as possible in order to avoid the introduction of dangerous lateral forces into the lifting gear. Transporting the load over longer distances is only possible slowly with two single-arm cranes acting on the ends of the load, since the building up of dangerous vibrations must absolutely be avoided.
In den 50-Jahren des letzten Jahrhunderts wurden Doppel- arm-Eisenbahnkräne eingesetzt, bei welchen an den Enden eines In the fifties of the last century, twin-arm railway cranes were used, at the ends of which a
Waggons jeweils ein Kranausleger gelagert ist, um z.B. Gleisjoche zu verlegen. Die bekannten Doppelarm-Eisenbahnkräne auf Waggonbasis sind jedoch nicht in der Lage, eine längere Last bis zu einer Abladestelle zu verfahren, z.B. ein vormontiertes Weichenstück von seiner Montagestelle zu seinem Verlegeort. Waggons each crane boom is mounted, for. To lay track yokes. The known wagon-based double-arm railway cranes, however, are unable to move a longer load to an unloading point, e.g. a pre-assembled turnout piece from its assembly point to its place of installation.
Die Schriften AT 292 256, EP 0 065 434 sowie GB 2 015 970 zeigen Eisenbahnkräne der einleitend genannten Art. Mit solchen Eisenbahnkränen ist jedoch ein synchronisiertes Manipulieren insbesondere langer Gleisjoche bzw. vormontierter Weichen- oder Kreuzungsstücke nicht zuletzt aufgrund der elastischen Eigenschaften und der beschränkten Torsionssteifigkeit solcher Lasten sehr schwierig und somit zeitraubend.  The documents AT 292 256, EP 0 065 434 and GB 2 015 970 show railway cranes of the aforementioned type. With such railway cranes, however, is a synchronized manipulation particular long track bumps or pre-assembled point or crossing pieces not least because of the elastic properties and the limited torsional rigidity such loads very difficult and therefore time consuming.
Die Erfindung setzt sich zum Ziel, die Nachteile des bekannten Standes der Technik zu überwinden und einen Eisenbahn- kran zu schaffen, welcher für besonders schwere und lange Las- ten geeignet ist, wie lange Gleisjoche, vormontierte Weichenoder Kreuzungsstücke od.dgl., und der ein rasches und sicheres Verfahren über längere Strecken bis zum Verlegeort gestattet. The object of the invention is to overcome the disadvantages of the known state of the art and to provide a railway crane which can be used for particularly heavy and long lasers. suitable, such as long track bumpers, pre-assembled switches or crossings or the like, and which allows a quick and safe method over long distances to the installation site.
Dieses Ziel wird mit einem Eisenbahnkran der einleitend genannten Art erreicht, der sich gemäß der Erfindung dadurch auszeichnet, dass die beiden Kranausleger gemeinsam eine Traverse mit Halteeinrichtungen für ein Gleisjoch, Weichenstück, Kreuzungsstück od.dgl. tragen.  This object is achieved with a railway crane of the aforementioned type, which is characterized according to the invention in that the two crane jibs together a traverse with holding devices for a track yoke, turnout piece, crossing piece or the like. wear.
Auf diese Weise wird ein Doppelarm-Kran in Form eines ge- lenkigen Zugs geschaffen, welcher eine große Länge einnehmen und damit auch lange Lasten wie vormontierte Weichen- oder Kreuzungsstücke transportieren kann. Gleichzeitig bildet der Eisenbahnkran eine einzige in Längsrichtung starr gekuppelte Einheit, die in einem Stück verfahren werden kann, wodurch kon- stante Abstände zwischen den Kranauslegern während der Fahrt gewährleistet sind. Dies minimiert die Einleitung von Querkräften in die Hebegeschirre der Kranausleger während des Transports. Über längere Strecken kann das Ladegut auch auf der Transportaufnahme abgestellt werden. Beides ermöglicht einen sicheren und schnellen Transport- und Verlegebetrieb. Der Eisenbahnkran der Erfindung eignet sich dadurch besonders für das Verlegen von vormontierten Weichenstücken, die meist von einem weiter entfernten Lager- oder Montageplatz bis zum Verlegeort herantransportiert werden müssen; eine hohe Transportgeschwin- digkeit minimiert die Belegungszeit des Transportgleises und damit Unterbrechungen des regulären Zugverkehrs auf dem Gleis.  In this way, a double-arm crane is created in the form of a articulated train, which occupies a large length and thus can also transport long loads such as pre-assembled turnout or crossing pieces. At the same time, the railroad crane forms a single, longitudinally rigidly coupled unit that can be moved in one piece, thus ensuring constant distances between the crane jibs while driving. This minimizes the introduction of shear forces into the jib boom hoists during transport. Over long distances, the load can also be parked on the transport receiver. Both allow a safe and fast transport and installation operation. The railway crane of the invention is thus particularly suitable for the laying of pre-assembled points pieces, which usually have to be transported from a more distant storage or assembly station to the installation site; A high transport speed minimizes the occupancy time of the transport track and thus interruptions of the regular train traffic on the track.
Die Traverse kann z.B. wie in dem Patent AT 505.402 beschrieben ausgebildet sein und ermöglicht, insbesondere wenn die Halteeinrichtungen, wie bevorzugt, hydraulisch betätigte Greifer aufweisen, ein rasches und sicheres Montieren, Verfahren und Verlegen eines Gleisjochs oder vormontierten Weichenoder Kreuzungsstücks.  The traverse can e.g. as described in the patent AT 505.402, and in particular when the holding devices, as preferred, comprise hydraulically actuated grippers, enable a rapid and secure mounting, moving and laying of a track yoke or pre-assembled turnouts or crossings.
Gemäß einer besonders bevorzugten Ausführungsform der Erfindung greift zumindest einer der Kranausleger an der Traverse über einen querverschieblichen Justierschlitten an, der bevor- zugt hydraulisch betätigt ist. Dadurch können geringfügige Justierbewegungen der Last unmittelbar beim Absetzen am Verlegeort durchgeführt werden, ohne dazu die gesamten Kranausleger synchronisiert betätigen zu müssen. According to a particularly preferred embodiment of the invention, at least one of the crane jibs engages the traverse via a transversely displaceable adjusting carriage, which preferably zugt hydraulically actuated. As a result, slight adjustment movements of the load can be carried out immediately when settling at the laying site, without having to operate the entire crane boom synchronized.
Besonders vorteilhaft ist es, wenn jeder Justierschlitten mit einem Neigungssensor ausgestattet ist. Mit solchen Neigungssensoren können entsprechende Anzeigen für den oder die Bedienungspersonen der Kranausleger angesteuert oder überhaupt die automatische Synchronisierung der Kranauslegerbewegungen geregelt werden, um das Auftreten von gefährlichen Kippmomenten bei der Betätigung der beiden Kranausleger zu vermeiden.  It is particularly advantageous if each adjusting slide is equipped with a tilt sensor. With such tilt sensors corresponding displays for the operator or operators of the crane boom can be controlled or even the automatic synchronization of the crane boom movements are regulated in order to avoid the occurrence of dangerous tilting moments in the operation of the two crane boom.
Gemäß einer weiteren bevorzugten Ausführungsform hat jeder Kranausleger an seinem Ende einen dreh- und schwenkbaren Kopf. Auch damit können weitere Justierbewegungen ohne die Notwendig- keit einer Bewegung der gesamten Kranausleger vorgenommen werden .  According to a further preferred embodiment, each crane boom has at its end a rotatable and pivotable head. This also allows further adjustment movements without the need for movement of the entire crane jib.
Die Justierschlitten können über Kettenglieder von den Köpfen abgehängt werden, um mehr Flexibilität erreichen zu können, falls die Hubhöhe wegen der Oberleitung dies erlaubt; um jegliche Schwingungstendenz zu unterbinden, können die Kettenglieder aber auch entfallen.  The adjusting carriages can be suspended from the heads via chain links in order to be able to achieve greater flexibility if the lifting height allows this because of the overhead line; But to prevent any tendency to vibrate, the chain links can also be omitted.
Gemäß einer bevorzugten Ausführungsform der Erfindung sind die Fahrgestelle über Abstandshaltestangen verbunden, die an ihren Enden jeweils gelenkig an einem Fahrgestell angreifen. Dadurch kann der Abstand zwischen den beiden Kranauslegern noch weiter erhöht werden, um noch längere Lasten transportieren und verlegen zu können, was besonders beim Verlegen von vormontierten Weichenstücken günstig ist.  According to a preferred embodiment of the invention, the chassis are connected by spacer rods which engage at their ends in each case articulated to a chassis. As a result, the distance between the two crane jibs can be further increased in order to transport and relocate even longer loads, which is particularly favorable when laying pre-assembled switch pieces.
Bevorzugt hat das Fahrgestell der Transportaufnahme Wag- gonlänge, wodurch standardisierte Transportwaggons mit offener Preferably, the chassis of the transport receptacle has wagon length, whereby standardized transport wagons with open
Ladefläche (sog. „Salmon Wagons") als Transportaufnahme eingesetzt werden können. Loading area (so-called "salmon wagons") can be used as a transport recording.
Die Erfindung wird nachstehend anhand eines in den beigeschlossenen Zeichnungen dargestellten Ausführungsbeispiels nä- her erläutert. In den Zeichnungen zeigt: Fig. 1 einen Eisenbahnkran gemäß der Erfindung in einer Seitenansicht ; The invention will be explained in more detail below with reference to an embodiment shown in the accompanying drawings.

In den Fig. 1 und 2 ist ein Eisenbahnkran 1 gezeigt, welcher auf einem Gleis 2 verfahrbar ist und zum Transportieren und Verheben einer Last 3 bestimmt ist. Die Last 3 ist bei- spielsweise ein Gleisjoch, vormontiertes Weichenstück, Kreuzungsstück, Brückenteil usw. Im gezeigten Fall ist die Last 3 ein Weichenstück, dass sich in an sich bekannter Weise aus Schienen 4 zusammensetzt, die auf Schwellen 5 vormontiert und z.B. mit entsprechenden Betätigungs- und Steuereinrichtungen (nicht gezeigt) für das Weichenherz ausgerüstet sind. Weichenstücke dieser Art können eine Länge von 20 - 30 m und ein Gewicht von 20 - 30 t und mehr erreichen.  In Figs. 1 and 2, a railway crane 1 is shown, which is movable on a track 2 and is intended for transporting and levying a load 3. The load 3 is, for example, a track yoke, pre-assembled turnout piece, crossing piece, bridge piece, etc. In the case shown, the load 3 is a turnout piece which is composed, in a manner known per se, of rails 4 which are pre-mounted on sleepers 5 and connected e.g. are equipped with appropriate actuation and control means (not shown) for the switch heart. Turnouts of this type can reach a length of 20-30 m and a weight of 20-30 t and more.
Der Kran 1 ist vom Doppelausleger- bzw. Doppelarm-Typ und umfasst einen ersten Kranausleger 7 und einen zweiten Kranaus- leger 8, zwischen denen eine Transportaufnahme 9 angeordnet ist. Die Kranausleger 7, 8 sind teleskopierend, um Horizontalachsen 10 schwenkbar und um Vertikalachsen 11 drehbar jeweils auf einem Fahrgestell 12, 13 gelagert.  The crane 1 is of the double-boom or double-arm type and comprises a first crane boom 7 and a second crane boom 8, between which a transport receptacle 9 is arranged. The crane jibs 7, 8 are telescoping, about horizontal axes 10 pivotally mounted and about vertical axes 11 rotatably mounted on a chassis 12, 13.
Die Fahrgestelle 12, 13 können selbstfahrend sein, bei- spielsweise mit einem Antrieb 14 ausgestattet, welcher von einer Führerkabine 15 aus gesteuert werden kann. Alternativ könnten die Fahrgestelle 12, 13 auch antriebslos sein und der Eisenbahnkran 1 z.B. mit Hilfe einer gesonderten Zugmaschine (nicht dargestellt) verfahren werden.  The chassis 12, 13 can be self-propelled, for example equipped with a drive 14, which can be controlled by a driver's cab 15. Alternatively, the chassis 12, 13 could also be unpowered and the railway crane 1 e.g. with the help of a separate tractor (not shown) are moved.
Auch die Transportaufnahme 9 ist auf einem eigenen Fahrgestell 16 angeordnet, das mit oder ohne Antrieb ausgestattet sein kann. Die Fahrgestelle 12, 13, 16 sind entweder über herkömmliche Kupplungseinrichtungen 17 direkt oder unter Zwischenschaltung von Abstandshaltestangen (Zug- und Druckstreben) 18 in der Art eines Zuges gelenkig aneinandergekuppelt . Der Eisen- bahnkran 1 kann daher trotz seiner beachtlichen Länge von z.B. 30 - 50 m üblichen Gleiskrümmungsradien gelenkig folgen. Zusätzlich können die Fahrgestelle 12, 13, 16 in herkömmlicher Art und Weise jeweils eine Mehrzahl um Vertikalachsen drehbar gelagerter Radsatzgruppen („Drehgestelle") 19 aufweisen, um den Krümmungsradien zu folgen. The transport receptacle 9 is arranged on a separate chassis 16, which can be equipped with or without drive. The chassis 12, 13, 16 are articulated either via conventional coupling devices 17 directly or with the interposition of spacer rods (tension and compression struts) 18 in the manner of a train hinged together. The iron therefore, track crane 1, despite its considerable length of, for example, 30-50 m, can follow conventional track radii of curvature. Additionally, the chassis 12, 13, 16 may each include a plurality of sets of wheels ("bogies") rotatably mounted about vertical axes in a conventional manner to follow the radii of curvature.
Die beiden Kranausleger 7, 8 mit ihren Fahrgestellen 12, 13 können auch als vorgefertigte Einheiten in der Art von Einzelarm-Kränen in den Eisenbahnkran 1 eingebaut werden. Beispie- le solcher vorgefertigten Einheiten sind Einarm-Eisenbahnkräne der Marke Multitasker 250 der Firma Kirow in Leipzig. Auch für die Transportaufnahme 9 mit ihrem Fahrgestell 16 können vorgefertigte Transportwaggons, z.B. sog. „Salmon Wagons", eingesetzt werden, welche die Länge üblicher Eisenbahnwaggons haben.  The two crane jibs 7, 8 with their chassis 12, 13 can also be installed as prefabricated units in the form of single-arm cranes in the railway crane 1. Examples of such prefabricated units are single-arm railway cranes of the Multitasker 250 brand from Kirow in Leipzig. For the transport receptacle 9 with its chassis 16, prefabricated transport wagons, e.g. so-called "salmon wagons" are used, which have the length of conventional railroad cars.
Die Abstandshaltestangen 18 werden für Belastungen im The spacer bars 18 are used for loads in the
Fahrbetrieb entsprechend den Gewichten der Kranausleger 7, 8 und Fahrgestelle 12, 13 einerseits und der Transportaufnahme 9 mit Fahrgestell 16 und Last 3 andererseits sowie unter Berücksichtigung von Gleissteigungen im Bereich von 1:30 bis 1:75 ausgelegt. Beispielsweise beträgt das Gewicht jedes Kranauslegers 7, 8 mit seinem Fahrgestell 12, 13 ca. 100 t, der Transportaufnahme 9 mit ihrem Fahrgestell 16 ca. 25 t, und der Last ca. 30 - 40 t, was eine statische theoretische Belastung der Abstandshaltestangen 18 im Bereich von ca. 5 t in Fahrtrichtung und eine Auslegung - mit Sicherheitsmarge - für ca. 8 t in Fahrtrichtung ergibt. Driving operation according to the weights of the crane boom 7, 8 and chassis 12, 13 on the one hand and the transport receptacle 9 with chassis 16 and load 3 on the other hand, and taking into account track gradients in the range of 1:30 to 1:75 designed. For example, the weight of each crane jib 7, 8 with its chassis 12, 13 is approximately 100 t, the transport receiver 9 with its chassis 16 approximately 25 t, and the load approximately 30-40 t, which is a static theoretical load on the spacer bars 18 in the range of about 5 t in the direction of travel and a design - with safety margin - for about 8 t in the direction of travel results.
Fig. 3 zeigt die Gestaltung der Enden der Kranausleger 7 und deren Hebegeschirre für die Last 3 im Detail. Jeder Kranausleger 7, 8 trägt an seinem Ende einen dreh- und schwenkbaren Kopf 20, von dem über Kettenglieder 21, z.B. Haken, Schäkel und Ösen, ein Justierschlitten 22 abgehängt ist. Die Justierschlitten 22 der beiden Kranausleger 7, 8 greifen an einer gemeinsamen Traverse 23 an, welche wiederum mit Einrichtungen 24, 25 zum Ergreifen der Last 3 ausgestattet ist. Die Einrichtungen 24, 25 können beispielsweise eine Vielzahl von Querbalken 24 mit jeweils - auch hydraulisch betätigbaren - Greifern 25, Klemmen, Zangen, Halteleisten usw. sein, um ein Gleisjoch oder vormontiertes Weichen- oder Kreuzungsstück mitsamt seinen Gleisen 4 und Schwellen 5 über seine ganze Länge abzustützen. Ein Beispiel einer derartigen Verlegetraverse 23 ist in der AT 505.402 derselben Anmelderin beschrieben. Fig. 3 shows the design of the ends of the crane boom 7 and their lifting harnesses for the load 3 in detail. Each crane boom 7, 8 carries at its end a rotatable and pivotable head 20, from which via chain links 21, such as hooks, shackles and eyelets, an adjusting slide 22 is suspended. The Justierschlitten 22 of the two crane boom 7, 8 engage a common cross member 23, which in turn is equipped with means 24, 25 for gripping the load 3. The devices 24, 25 may, for example, a plurality of crossbars 24th with each - also hydraulically operated - grippers 25, clamps, pliers, retaining strips, etc., to support a track yoke or pre-assembled point or crossing piece together with its tracks 4 and sleepers 5 over its entire length. An example of such a laying traverse 23 is described in the AT 505,402 of the same Applicant.
Die Justierschlitten 22 ermöglichen eine geringfügige horizontale Hin- und Herbewegung der Traverse 23 relativ zu den Kranauslegern 7, 8 bzw. deren Köpfen 20. Die Justierschlitten 22 können dabei Hydraulikzylinder enthalten, deren einer Teil an den Köpfen 20 abgehängt ist und deren anderer, dazu relativ- verschieblicher Teil die Traverse 23 trägt.  The Justierschlitten 22 allow a slight horizontal reciprocation of the crossbar 23 relative to the crane jibs 7, 8 and their heads 20. The Justierschlitten 22 may include hydraulic cylinders, one part of which is suspended from the heads 20 and the other, relative thereto - Sliding part of the crossbar 23 carries.
Die Justierschlitten 22 sind bevorzugt mit eingebauten Neigungssensoren 26 ausgerüstet, welche die Neigung der Traver- se 23 beispielsweise mit Hilfe eines Pendels messen. Die Neigungssensoren 26 können alternativ auch im Bereich der Kettenverbindung 21 angeordnet werden, z.B. in zwei Schäkel so eingebaut, dass sie Kippwinkel in allen drei Raumrichtungen erkennen können. Die Neigungssensoren 26 können eine Anzeigeeinrichtung für den bzw. die Bedienungspersonen steuern oder auch direkt die Antriebe der Kranausleger 7, 8 für deren Teleskop-, Schwenk- und Drehbewegung steuern, um eine möglichst waagrechte Lage der Traverse 23 zu erreichen.  The adjusting carriages 22 are preferably equipped with built-in inclination sensors 26, which measure the inclination of the traverses 23, for example with the aid of a pendulum. The inclination sensors 26 may alternatively be arranged in the region of the chain connection 21, e.g. installed in two shackles so that they can detect tilt angles in all three spatial directions. The inclination sensors 26 can control a display device for the operator (s) or also directly control the drives of the crane jibs 7, 8 for their telescopic, pivoting and rotary movement in order to achieve as horizontal a position as possible of the traverse 23.
Es versteht sich, dass beim Ausschwenken der Kranausleger 7, 8 von der Transportstellung über der Transportaufnahme 9 in die in Fig. 2 gezeigte Stellung seitlich des Gleises 2 zum Aufnehmen und Absetzen der Last 3 die Kranausleger 7, 8 entsprechend teleskopierend ausfahren, um die Einleitung von Querkräften in die Hebegeschirre 20 - 22 der Traverse 23 zu vermeiden, und beim Zurückschwenken entsprechend teleskopierend einfahren. It is understood that when swinging the crane boom 7, 8 from the transport position on the transport receptacle 9 in the position shown in Fig. 2 side of the track 2 for receiving and depositing the load 3, the crane boom 7, 8 extend telescopically according to the initiation of transverse forces in the lifting harnesses 20-22 of the traverse 23 to avoid, and retract when retracting telescoping accordingly.
Die Steuerungen der beiden Kranausleger 7, 8 können dazu auch elektronisch gekoppelt und bevorzugt durch die Sensoren 26 entsprechend geregelt werden. Ein einziges Steuerungssystem kann damit die volle Kontrolle über den gesamten Eisenbahnkran 1 und alle seine Bewegungen übernehmen. Die Erfindung ist nicht auf die dargestellten Ausführungsformen beschränkt, sondern umfasst alle Varianten und Modifikationen, die in den Rahmen der angeschlossenen Ansprüche fallen. The controls of the two crane jibs 7, 8 can also be electronically coupled and preferably controlled by the sensors 26 accordingly. A single control system can thus take full control of the entire railway crane 1 and all its movements. The invention is not limited to the illustrated embodiments, but includes all variants and modifications that fall within the scope of the appended claims.
