Description

Portalkran zum Transportieren von GleisjochenGantry crane for transporting track yokes
Die Erfindung betrifft einen Portalkran zum Transportieren von Gleisjochen gemäß den im Oberbegriff von Anspruch 1 angeführten Merkmalen.The invention relates to a gantry crane for transporting track yokes according to the features cited in the preamble of claim 1.
Es ist bereits - durch EP 0 505 240 A 1 - ein derartiger Portalkran zum Transportieren von Gleisjochen bekannt. Dieser weist einen Portalrahmen auf, der mit Hilfe von vier jeweils höhenverstellbaren Raupenfahrwerken ver¬ fahrbar ist. Am Portalrahmen sind in dessen Längsrichtung voneinander dis¬ tanziert Hebewerkzeuge zum Erfassen des Gleisjoches angeordnet. Außer¬ dem sind noch höhenverstellbare Spurkranzrollen vorgesehen, mit deren Hil¬ fe der Portalkran auch auf einem Gleis verfahrbar ist.It is already known - by EP 0 505 240 A 1 - such a gantry crane for transporting track yokes. This has a portal frame, which is ver¬ mobile with the help of four each height-adjustable crawler tracks. Lifting tools for detecting the track yoke are arranged in the longitudinal direction of each other on the portal frame. In addition, height-adjustable flange wheels are provided, with the help of which the gantry crane can also be moved on a track.
Es ist auch - gemäß DE 2 309 930 A 1 - ein weiterer Portalkran zum Verle¬ gen von Gleisjochen mit einer das zu transportierende Gleisjoch erfassenden Trageeinrichtung bekannt. Der Portalkran weist höhen- und seitenverstellbare Raupenfahrwerke sowie beidseits davon angeordnete höhenverstellbare Hubstempel aut. Mehrere dieser Portalkrane werden über Spurkranzrollen auf das abgelegte Gleisjoch verfahren und durch entsprechende Hebewerk¬ zeuge mit dem Gleisjoch in Verbindung gebracht. Anschließend wird das Gleisjoch durch Absenken der Hubstempel auf das Schotterbett angehoben und das Raupenfahrwerk durch Seiten- und Höhenverstellung unterhalb des Gleisjoches auf die Schotterbettung abgesenkt. Nach abschließendem Anhe¬ ben aller vier Hubstempel wird das Gleisjoch mit Hilfe der Raupenfahrwerke in die Umbaulücke verfahren.It is also known - according to DE 2 309 930 A 1 - another gantry crane for laying track rails with a carrying device which detects the track yoke to be transported. The gantry crane has height- and side-adjustable crawler tracks as well as height-adjustable lifting cams arranged on both sides thereof. Several of these gantry cranes are moved onto the deposited track yoke via flange rollers and brought into contact with the track yoke by means of appropriate lifting tools. Subsequently, the track yoke is raised by lowering the lifting ram on the ballast bed and the crawler undercarriage lowered by side and height adjustment below the track yoke on the ballast bedding. After a final lifting of all four lifting pistons, the track yoke is moved into the remover using the crawler tracks.
Schließlich ist noch durch DE 3340 739 A 1 eine Gleisbaumaschine für das Auswechseln eines Gleisjoches bekannt. Diese Gleisbaumaschine besteht im wesentlichen aus einem langgestreckten Träger, der endseitig wahlweise je¬ weils durch ein Schienen- oder Raupenfahrwerk abstützbar ist. Diese Aufgabe wird erfindungsgemäß mit einem eingangs genannten Portal¬ kran dadurch gelöst, dass jeder Fahrwerksrahmen durch eine mittig zwischen den beiden Raupenfahrwerken angeordnete, die beiden Querträger mit dem Längsträger verbindende vertikale Drehachse relativ zum Längsträger verdrehbar ausgebildet ist.Finally, DE 3340 739 A1 discloses a track-laying machine for exchanging a track yoke. This track laying machine consists essentially of an elongated carrier, which is optionally supported by a rail or track undercarriage. This object is achieved according to the invention with a portal crane mentioned above in that each chassis frame is rotatable relative to the longitudinal carrier by a centrally disposed between the two crawler tracks, the two cross members with the longitudinal beam connecting vertical axis of rotation.
Durch diese konstruktiv relativ einfache Ausbildung ist die Beweglichkeit des Portalkranes wesentlich verbessert, so dass das erfasste Gleisjoch problem¬ los auch quer bzw. schräg zur Gleislängsrichtung transportierbar ist. Dabei ist von besonderem Vorteil, dass die Rahmenstabilität in keiner Weise beein¬ trächtigt ist. Die Lenkbarkeit des Fahrwerksrahmens ist sehr einfach durch unterschiedliche Beaufschlagung der Fahrantriebe möglich.As a result of this structurally relatively simple design, the mobility of the gantry crane is substantially improved, so that the detected track yoke can also be transported transversely or obliquely to the track longitudinal direction in a problem-free manner. It is of particular advantage that the frame stability is in no way impaired. The steerability of the chassis frame is very easy by different loading of the drives possible.

Der in Fig. 1 ,2 und 3 ersichtliche Portalkran 1 weist einen mittigen Längsträ¬ ger 5 auf, der durch zwei Fahrwerksrahmen 24 mit Raupenfahrwerken 4 ver¬ bunden ist. Jeder Fahrwerksrahmen 24 ist jeweils durch zwei Vertikalträger 20 und zwei normal bzw. im Winkel zu einer Längsrichtung 2 des Längsträ¬ gers 5 verlaufende Querträger 6 gebildet. Jeder Fahrwerksrahmen 24 ist durch eine mittig zwischen den beiden Raupenfahrwerken 4 angeordnete, die beiden Querträger 6 mit dem Längsträger 5 verbindende vertikale Drehachse 25 relativ zum Längsträger 5 verdrehbar ausgebildet. Wie in Fig. 3 ersichtlich, ist ein maximaler Verdrehwinkel α ± 15° des Fahrwerkrahmens 24 in bezug auf die Längsrichtung 2 des Längsträgers 5 möglich. Die Drehachse 25 ver¬ läuft normal in bezug auf die Längsrichtung der beiden Querträger 6. Am Längsträger 5 sind im wesentlichen aus einem Verbrennungsmotor und einer Hydraulikpumpe gebildete Energiequellen 7 befestigt. Außerdem sind am Längsträger 5 in Rahmenlängsrichtung voneinander distanzierte Füh¬ rungskörper 8 höhenverstellbar gelagert und jeweils mit Antrieben 9 zur Hö¬ henverstellung verbunden. Das untere Ende jedes Führungskörpers 8 ist mit einem horizontal verlaufenden Träger 10 verbunden, der seinerseits mit zwei in Trägerlängsrichtung voneinander distanzierten Hebewerkzeugen 11 ver¬ bunden ist. Jeder Träger 10 ist um eine vertikale Achse 12 drehbar am ge¬ nannten Führungskörper 8 gelagert. Die Hebewerkzeuge 11 sind in der be¬ kannten Weise zangen- bzw. hakenförmig zum formschlüssigen Erfassen eines Schienenkopfes oder eines Schienenfußes eines zu transportierenden Gleisjoches 13 ausgebildet.The gantry crane 1 shown in FIGS. 1, 2 and 3 has a central longitudinal girder 5, which is connected by two chassis frames 24 with crawler tracks 4. Each chassis frame 24 is formed in each case by two vertical beams 20 and two transverse beams 6 running normal or at an angle to a longitudinal direction 2 of the longitudinal beam 5. Each chassis frame 24 is formed by a centrally disposed between the two crawlers 4, the two cross member 6 with the longitudinal member 5 connecting vertical axis of rotation 25 relative to the longitudinal member 5 rotatable. As can be seen in FIG. 3, a maximum angle of rotation α ± 15 ° of the chassis frame 24 with respect to the longitudinal direction 2 of the longitudinal member 5 is possible. The axis of rotation 25 ver¬ runs normal with respect to the longitudinal direction of the two cross member. 6 On the longitudinal member 5 are substantially formed of an internal combustion engine and a hydraulic pump energy sources 7 are attached. In addition, guide bodies 8 which are distanced from each other on the longitudinal member 5 in the longitudinal direction of the frame are mounted in a height-adjustable manner and in each case connected to drives 9 for height adjustment. The lower end of each guide body 8 is connected to a horizontally extending support 10 which in turn is connected to two lifting tools 11 which are spaced apart from each other in the longitudinal direction of the support. Each carrier 10 is rotatably mounted about a vertical axis 12 on ge called guide body 8. The lifting tools 11 are formed in the manner known per se or hook-shaped for the positive engagement of a rail head or a rail foot of a track yoke 13 to be transported.
Jedes der vier genannten Raupenfahrwerke 4 besteht aus zwei in Rahmen¬ längsrichtung bzw. in Längsrichtung des Längsträgers 5 voneinander distan¬ zierten Fahrwerkseinheiten 14,15. Beide Fahrwerkseinheiten 14,15 sind je¬ weils durch einen um eine normal zur Rahmenlängsrichtung verlaufende Ho¬ rizontalachse 16 verschwenkbar am Vertikalträger 20 gelagerten Fahrwerks- träger 17 miteinander verbunden. Jede Fahrwerkseinheit 14,15 ist ihrerseits um eine normal zur Rahmenlängsrichtung verlaufende Fahrwerk- Horizontalachse 18 verschwenkbar am Fahrwerksträger 17 gelagert. Jeder als Raupenfahrwerk 4 ausgebildeten Fahrwerkseinheit 14 bzw. 15 ist ein ei¬ gener Fahrantrieb 19 zugeordnet.Each of the four caterpillar tracks 4 consists of two chassis units 14,15 which are distanced from one another in the longitudinal direction of the frame or in the longitudinal direction of the longitudinal member 5. Both chassis units 14, 15 are each connected to one another by a chassis carrier 17 mounted pivotably on the vertical carrier 20 about a horizontal axis 16 extending normal to the longitudinal direction of the frame. Each chassis unit 14,15 is in turn mounted on a running normal to the frame longitudinal direction chassis horizontal axis 18 pivotally mounted on the chassis support 17. Each chassis unit 14 or 15 designed as a crawler track 4 is assigned an ei¬ gener travel drive 19.
Die beiden Fahrwerk-Horizontalachsen 18 der beiden Fahrwerkseinheiten 14,15 sind in einem Abstand von etwa 2,5 bis etwa 3,5 Meter, vorzugsweise 3 Meter voneinander distanziert angeordnet. Wie insbesondere in Fig. 2 er¬ sichtlich ist, sind zur Höhenverstellung jedes Führungskörpers 8 jeweils zwei Antriebe 9 am Längsträger 5 befestigt. Höhenverstellantriebe 3 sind innerhalb der teleskopartig in vertikaler Richtung verlängerbaren, zweiteiligen Vertikal¬ träger 20 angeordnet. Wie in der linken Hälfte der Fig. 2 ersichtlich, sind die unteren Enden jeweils zweier in vertikaler Richtung verstellbarer und jeweils einem Raupenfahrwerk 4 zugeordneter Vertikalträger 20 durch einen Verbin- dungsträger 21 miteinander verbunden. Auf diesem ist der genannte Fahr- werksträger 17 um die Horizontalachse 16 verschwenkbar befestigt. Die je¬ weils oberen Hälften der beiden zweiteilig ausgebildeten Vertikalträger 20 sind mit einem im Querträger 6 verschiebbar gelagerten Führungsrohr 22 verbunden. Dieses ist mit Hilfe eines Querverstellantriebes 23 mitsamt den Vertikalträgern 20 und den zugeordneten Fahrwerkseinheiten 14,15 in Längs¬ richtung des Querträgers 6 verstellbar.The two chassis horizontal axes 18 of the two chassis units 14,15 are spaced apart at a distance of about 2.5 to about 3.5 meters, preferably 3 meters apart. As can be seen in particular in FIG. 2, in each case two drives 9 are fastened to the longitudinal member 5 for adjusting the height of each guide body 8. Height adjustment drives 3 are arranged within the telescopically extendable in the vertical direction, two-part Vertikal¬ carrier 20. As can be seen in the left-hand half of FIG. 2, the lower ends of two vertical supports 20 which are each adjustable in the vertical direction and are each assigned to a crawler undercarriage 4 are connected by a link. carrier 21 connected to each other. On this said carriage support 17 is pivotally mounted about the horizontal axis 16. The respective upper halves of the two two-part vertical supports 20 are connected to a guide tube 22 which is displaceably mounted in the cross member 6. This is adjustable by means of a Querverstellantriebes 23 together with the vertical beams 20 and the associated chassis units 14,15 in Längs¬ direction of the cross member 6.
Zum Ausbau eines Gleisjoches 13 wird der Portalkran 1 mit Hilfe der Rau¬ penfahrwerke 4 auf dem seitlich an das verlegte Gleis anschließenden Be¬ reich der Schotterbettung bzw. des Erdplanums verfahren, bis die Umbaulü¬ cke erreicht ist. Anschließend erfolgt ein Absenken des Längsträgers 5 mit¬ samt den Querträgern 6 durch entsprechende Beaufschlagung der Höhen- verstellantriebe 3. Die Antriebe 9 werden darauffolgend so lange beauf¬ schlagt, bis die Hebewerkzeuge 11 unmittelbar oberhalb der Schienen des zu erfassenden Gleisjoches 13 zu liegen kommen. Nachdem die genannten He¬ bewerkzeuge 11 formschlüssig mit der zugeordneten Schiene in Eingriff ge¬ bracht wurden, erfolgt durch ein Beaufschlagen der Höhenverstellantriebe 3 und der Antriebe 9 ein Abheben des Gleisjoches 13 (s. Fig.1 ).To remove a track yoke 13, the gantry crane 1 is moved by means of the rough traveling trolleys 4 on the area of the ballast bed or ground plane which adjoins the laid track laterally, until the transom is reached. Subsequently, the longitudinal member 5 is lowered together with the transverse supports 6 by appropriate action on the height adjustment drives 3. The drives 9 are subsequently loaded until the lifting tools 11 come to lie directly above the rails of the track yoke 13 to be detected. After said lifting tools 11 have been positively engaged with the associated rail, lifting of the track yoke 13 (see FIG.
Durch Beaufschlagung der Fahrantriebe 19 kann nunmehr das angehobene Gleisjoch 13 abtransportiert werden, wobei infolge der speziellen Ausbildung und Lagerung der Raupenfahrwerke 4 eine verbesserte Anpassung an eine unebene Fahrfläche gewährleistet ist. Dabei sind die einzelnen Fahrwerks¬ einheiten 14,15 sowohl um die Fahrwerk-Horizontalachse 18 als auch um die Horizontalachse 16 verschwenkbar. Der Ausdruck "horizontal" bezieht sich auf jene Situation, in der der Portalkran 1 auf einer horizontalen Ebene steht. By applying the traction drives 19, the raised track yoke 13 can now be transported away, wherein due to the special design and storage of the crawler tracks 4 improved adaptation to an uneven running surface is ensured. The individual chassis units 14, 15 are pivotable both about the chassis horizontal axis 18 and about the horizontal axis 16. The term "horizontal" refers to the situation in which the gantry crane 1 stands on a horizontal plane.
