A laying directly out of a stack or an automatable laying device except as part of a larger track renewal train are not yet known.
Von daher liegt der Erfindung das Problem zugrunde, eine automatisierbare Vorrichtung zum gezielten Auslegen von Y-Schwellen, insbesondere von beim Transport gestapelten Schwellen, vorzuschlagen.
Das problem wird erfindungsgemäß durch die Merkmale der Ansprüche 1 und 17 gelöst. Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen beschrieben.The invention is therefore based on the problem of proposing an automatable device for the targeted laying out of Y-sleepers, in particular of sleepers stacked during transport.
The problem is solved by the features of
Die Lösung umfasst eine Vorrichtung zum Auslegen von Y-Schwellen von einem Transporfinragen in Solllage auf ein Gleisbett mittels eines Kranes, der mit einem um 180 ° drehbaren Lastaufnahmemittel für die Schwellen ausgestattet ist, mit einer motorisch bewegbaren Traverse mit Koppeleinrichtung zum Kran, mindestens ein mit der Traverse drehfest verbundenes Querhaupt, mindestens zwei von einander beabstandete und von dem Querhaupt vertikal sich nach unten erstreckende Schenkel für ein Umgreifen zumindest der untersten einer Mehrzahl aufeinander gestapelter Y-Schwellen, die mit dem Querhaupt verbunden sind und eine mit dem Schenkel verbundenen Halteeinrichtung für zumindest die unterste der gestapelten Schwellen. Eine weitergehende Lösung umfasst einen Bagger oder Kran, ausgestattet mit einer derartigen Vorrichtung.The solution comprises a device for laying out Y-thresholds of a Transportinragen in desired position on a track bed by means of a crane which is equipped with a 180 ° rotatable load-carrying means for the thresholds, with a motor-movable crossbar with coupling device to the crane, at least one with the traverse rotatably connected crosshead, at least two spaced from each other and from the crosshead vertically downwardly extending leg for embracing at least the bottom of a plurality of stacked Y-thresholds, which are connected to the crosshead and connected to the leg holding device for at least the lowest of the stacked sleepers. A further solution includes an excavator or crane equipped with such a device.
Obwohl Y-Schwellen aus unterschiedlichen Materialien hergestellt werden können, werden im Folgenden zur Darstellung der Erfindung nur Y-Stahlschwellen betrachtet.
Die Y-Stahlschwelle besteht aus vier Teilen, Abschnitten aus Breitflanschträgern, von denen zwei lange Teile S-förmig gebogen und zwei gegenläufig gebogene Breitflanschträger zu einer Gabel zusammengesetzt werden. Am Gabelende werden parallel dazu zwei kurze Breitflanschträger positioniert. Sowohl am stabförmigen Ende der Schwelle, an dem die beiden gebogenen Breitflanschträger zusammenkommen, als auch dem Gabelende werden die Träger untereinander durch Querriegel verbunden, so dass sich bei jeder Y-Stahlschwelle drei Doppellauflager und drei Schienenbefestigungspunkte ergeben. Die Enden der Breitflanschträger sind abgeschrägt. Querriegel und Breitflanschträger werden miteinander verschweißt.Although Y-sills can be made of different materials, only Y-steel sleepers will be considered below to illustrate the invention.
The Y-steel sleeper consists of four parts, sections of wide-flange girders, of which two long parts are bent in an S-shape and two counter-bent wide-flange girders are assembled into a fork. At the fork end, two short wide flange beams are positioned parallel to it. Both at the rod-shaped end of the threshold, at which the two curved Breitflanschträger come together, as well as the fork end, the carriers are interconnected by crossbars, so that each Y-steel sleeper three double bearing and three Schienenbefestigungspunkte arise. The ends of the Breitflanschträger are chamfered. Crossbar and wide flange are welded together.
In Richtung Gleisachse werden dann jeweils ein Gabelende und nachfolgend ein Stabende positioniert, wodurch sich die Notwendigkeit ergibt ,jede zweite Y-Stahlschwelle um 180° versetzt zu der vorhergehenden auf dem Gleisbett anzuordnen.In the direction of the track axis, a fork end and subsequently a rod end are then positioned in each case, which results in the need to place every second Y steel sleeper offset by 180 ° to the preceding one on the track bed.
Derartige Y-Schwellen werden in der Regel mit den Befestigungsteilen in Vormontagestellung ausgeliefert, wobei sechs oder mehr Schwellen gleichsinnig übereinander gestapelt und durch Umgreifungsbänder in ihrer Position gehalten werden.Such Y-thresholds are usually shipped with the fasteners in pre-assembly, with six or more thresholds are stacked in the same direction and held by Umgreifungsbänder in position.
Die Lösung sieht eine kreuzförmige Anordnung einer Traverse mit einem Querhaupt vor, wobei mindestens von dem Querhaupt sich vertikal nach unten erstreckende Schenkel vorgesehen sind, die von einem Stapel mindestens die unterste Schwelle greifen oder fixieren kann.The solution provides a cross-shaped arrangement of a traverse with a crosshead, wherein at least from the crosshead are provided vertically downwardly extending legs, which can grab or fix at least the lowest threshold of a stack.
Wenn das Querhaupt so gestaltet ist, dass die Schenkel am Gabelende die parallelen Haupt- und Nebenträger erfassen, könnte ein weiterer Schenkel am anderen Ende der Traverse das stabförmige Ende bzw. die beiden S-förmig gebogenen Hauptträger umgreifen.If the crosshead is designed so that the legs detect the parallel main and secondary beams at the fork end, another leg could engage around the other end of the traverse the rod-shaped end or the two S-shaped curved main carrier.
Im Regelfall ist jedoch vorgesehen, dass die Traverse mit zwei Querhaupten mit jeweils zwei Schenkeln verbunden wird, wobei die Schenkel an dem einen Querhaupt das stabförmige Ende der Y-Schwelle seitlich umgreifen, während die anderen beiden Schenkel an dem zweiten Querhaupt das Gabelende der Y-Schwelle seitlich umgreifen. Die Schenkel an der Traverse oder die Traverse an dem Querhaupt können auch verschieblich angeordnet sein, beispielsweise wenn die Vorrichtung für Schwellen für Gleise breiterer und schmalerer Spurweite auszulegen ist.As a rule, however, it is provided that the traverse is connected with two cross-heads, each with two legs, the legs on one cross-head laterally embrace the rod-shaped end of the Y-threshold, while the other two legs on the second crosshead, the fork end of the Y- Embrace threshold laterally. The legs on the traverse or the traverse on the crosshead can also be arranged displaceably, for example if the device is to be designed for sleepers for tracks wider and narrower gauge.
In einer Ausformung der Erfindung ist die Halteeinrichtung für die Schwelle am Schenkel so ausgebildet, dass sie im unteren Bereich der Schenkel angeordnet, aus in horizontaler Richtung bewegbaren Bolzen besteht, wobei gemäß einer weiteren Variante der Erfindung an jedem Schenkel zwei Halteeinrichtungen für zwei untereinander bzw. übereinander angeordnete Schwellen eines Schwellenstapel bestimmt sind. Dadurch wird die Schwelle von jeder Seite her gehalten, vorzugsweise mittels je zwei Bolzen an zwei Schenkeln.In one embodiment of the invention, the holding device for the threshold on the leg is formed so that it is arranged in the lower region of the legs, consists of horizontally movable pin, wherein according to a further variant of the invention on each leg two holding devices for two with each other or stacked thresholds of a threshold stack are determined. Thereby, the threshold is held from each side, preferably by means of two bolts on two legs.
Die Bolzen können ausgefahren sein und untergreifen dann die Schwellen bzw. liegen an der Unterseite einer Schwelle an. Vorzugsweise die Schwellensohle oder auch ein Flansch ruht auf dem ausgefahrenen Bolzen. Wenn die Bolzen eingefahren werden, wird demzufolge die Schwelle freigegeben und nicht mehr gehalten. Bei zwei übereinander angeordneten Bolzen würde in einem Stapel nur die untere Schwelle freigegeben werden, während die darüber liegende Schwelle von den zweiten Bolzen der Halteeinrichtung in Position gehalten wird. Die Bolzen können als elektrisch oder hydraulisch beaufschlagbare Teleskope ausgebildet sein, also beispielsweise wie ein normaler Hydraulikzylinder.The bolts may be extended and then engage under the thresholds or lie at the bottom of a threshold. Preferably, the threshold sole or a flange rests on the extended bolt. As a result, when the bolts are retracted, the threshold is released and no longer held. With two bolts arranged one above the other, only the lower threshold would be released in a stack, while the overlying threshold would be held in position by the second bolts of the holding device. The bolts can be designed as electrically or hydraulically loadable telescopes, so for example as a normal hydraulic cylinder.
Vorzugsweise werden gemäß einer Variante der Erfindung die bewegbaren Bolzen an ihrem Kopf als Kugel oder Rolle ausgebildet damit, beim Zurückziehen des Bolzens der Verschleiß aufgrund Reibung zwischen Schwelle und Bolzen minimiert wird.Preferably, according to a variant of the invention, the movable bolts are formed on their head as a ball or roller so that when retracting the bolt, the wear due to friction between the threshold and bolt is minimized.
In einer grundsätzlich von der bisher beschriebenen Halteeinrichtung divergierenden Ausführungsform der Erfindung ist vorgesehen, dass die an dem Querhaupt bzw. der Traverse angeordneten und mit diesem verbundenen Schenkel schwenkbeweglich zum Querhaupt bzw. zur Traverse ausgebildet sind und die Halteeinrichtung einen Schwenkantrieb für den Schenkel umfasst, der den Schenkel relativ zum Querhaupt bzw. zur Traverse um einen vorgebbaren Winkelbetrag im Bereich von 5 bis 30° vorzugsweise etwa 15° oder weniger schwenkbar macht. In dieser Bauweise sollten die Schenkel an der der Schwelle zugewandten Seite mit einem rutschfesten elastischen Belag beschichtet sein, damit beim Schwenken der Schenkel diese an den Kanten z. B. der Breitflanschträger, aus denen die Schwelle zusammengesetzt ist, keine Beschädigung erfahren, jedoch andererseits Schwellen zwischen den Schenkeln eingeklemmt werden können sobald der Schwenkantrieb der Halteeinrichtung einen entsprechenden Schwenkwinkel überschritten hat. Der Belag besteht vorzugsweise aus Kunststoff, vorzugsweise einem Elastomer oder aus Gummi, welcher die geforderten rutschfesten und elastischen Eigenschaften besitzt.In a fundamentally diverging from the holding device described so far embodiment of the invention, it is provided that the arranged on the crosshead or the traverse and connected to this leg are pivotally adapted to the crosshead or to Traverse and the holding device comprises a pivot drive for the leg, the makes the leg relative to the crosshead or to the cross member by a predetermined angular amount in the range of 5 to 30 °, preferably about 15 ° or less pivoting. In this design, the legs should be coated on the side facing the threshold with a non-slip elastic coating, so when swiveling the legs this at the edges z. B. the wide flange, from which the threshold is composed, experience no damage, however, thresholds between the legs can be clamped once the pivot drive of the holding device has exceeded a corresponding pivoting angle. The covering is preferably made of plastic, preferably an elastomer or of Rubber, which has the required non-slip and elastic properties.
Anstelle der Aufnahme eines Stapels durch die zuvor beschriebene Form der Vorrichtung, bei der die Halteeinrichtung in Form von bewegbaren Bolzen unter die unterste Schwelle greift, wird bei dieser Ausführungsform der Schwenkantrieb in Funktion gesetzt, um die Schenkel geringfügig auswärts zu spreizen, also den Schenkelabstand an ihren Spitzen vergrößern und sodann nach Umgreifen eines oder zweier übereinander angeordneter Schwellenstapel die Schenkel zurück geschwenkt, sodass die Enden der Schenkel näher zusammen kommen, als am Querhaupt bzw. der Traverse. Der Schwenkantrieb wird so lange in Funktion gelassen, bis die Schenkel bzw. ihr rutschfester Belag an der untersten Schwelle anliegt und ein gewisser Hydraulikdruck oder eine gewisse Stromaufnahme zu verzeichnen ist, sodass der Bediener sicher ist, dass die Schenkel bei einem Anheben der Schwellen pakete mit der Vorrichtung ihre Soll-Lage nicht verlassen und die Schwellen mit angehoben werden. Diese Überwachung des Elektroantriebes oder Hydraulikantriebes kann auch automatisch durch entsprechende Regel- oder Lastbegrenzungseinrichtungen geschehen.Instead of receiving a stack by the previously described form of the device in which the holding device engages in the form of movable bolts below the lowest threshold, in this embodiment, the pivot drive is put into operation to spread the legs slightly outwards, so the leg distance enlarge their tips and then after embracing one or two superimposed threshold stack, the legs pivoted back, so that the ends of the legs come closer together than on the crosshead or the traverse. The rotary actuator is left in operation until the legs or their non-slip coating is at the lowest threshold and a certain hydraulic pressure or a certain power consumption is recorded, so that the operator is sure that the legs with a lifting of the threshold packages with the device does not leave its desired position and the thresholds are raised with. This monitoring of the electric drive or hydraulic drive can also be done automatically by appropriate control or load limiting devices.
In weiterer Ausführung der Erfindung kann nunmehr eine einzelne Schwelle oder auch ein Schwellenstapel, der von der Vorrichtung angehoben wurde mit Hilfe eines zwischen Traverse und Kran angeordneten Drehmotors durch eine Schwenkbewegung der Traverse um 180° gedreht werden, um dann wechselweise eine Schwelle abzulegen und die nächste in Gleisrichtung, um 180° gedreht zu der abgelegten Schwelle, zu positionieren.In a further embodiment of the invention, now a single threshold or a threshold stack, which has been raised by the device using a arranged between Traverse and crane rotary motor can be rotated by a pivoting movement of the crosshead by 180 °, then alternately store a threshold and the next in the track direction, rotated 180 ° to the stored threshold position.
Damit sichergestellt ist, dass die Schwellenstapel oder einzelne Schwellen stets in der gleichen Position aufgenommen werden, ist gemäß einer weiteren Ausführungsform der Erfindung eine Anschlag vorzusehen, der die Schwelle an einer vorbestimmten Stelle kontaktiert und so eine Ausrichtung der Vorrichtung relativ zur Schwelle gestattet. Ein derartiger Anschlag könnte beispielsweise als vertikales Schwert ausgebildet sein, wobei das Schwert selbst an der Traverse oder an dem Querhaupt angeordnet ist und vertikal in den Schwellenstapel eingefahren wird beim Ansetzen der Vorrichtung zur Aufnahme des Schwellenstapels. Es kann jedoch auch vorgesehen werden Anschläge an den Schenkeln direkt anzuordnen.In order to ensure that the threshold stacks or individual thresholds are always received in the same position, according to a further embodiment of the invention, a stopper is provided which contacts the threshold at a predetermined location and thus permits alignment of the device relative to the threshold. Such a stop could for example be designed as a vertical sword, the sword itself is arranged on the traverse or on the crosshead and is moved vertically into the threshold stack when applying the device for receiving the threshold stack. However, it can also be provided to arrange stops on the legs directly.
Zur lagegenauen Positionierung der Schwellen auf Gleisbett ist in einer Ausführungsform der Erfindung vorgesehen, dass mindestens an einem Ende der Traverse eine Kamera zur Überwachung der Schwellenposition angebracht ist. Bei Bedarf kann auch eine zweite Kamera am anderen Traversenende oder z.B. einem Querhaupt angeordnet werden.For positionally accurate positioning of the sleepers on trackbed is provided in one embodiment of the invention that at least at one end of the traverse a camera is mounted to monitor the threshold position. If necessary, a second camera may also be provided at the other end of the truss or e.g. a crosshead can be arranged.
Die erfindungsgemäße Vorrichtung kann erfindungsgemäß an der Baustelle an einem handelsüblichen Kran oder Bagger, vorzugsweise einen bereits mit Hydraulikantrieb ausgestatteten mobilen Bagger angebracht werden. Das erspart Investkosten, wenn der häufig vorhandene Bagger damit ausgerüstet wird. Seltener könnte jedoch ein derartiger Kran als Spezialkran mit einer erfindungsgemäßen Vorrichtung ausgerüstet, wobei alle Antriebe und Teile der Vorrichtung mit einer Fernsteuerung beispielsweise für Drehmotor, Schwenken der Schenkel, Bewegen der Kamera, Ausfahren oder Einfahren der Bolzen der Halteeinrichtung, bedienbar sind. Andererseits kann die Vorrichtung einfach als Vorsatzeinrichtung an einem auf jeder Baustelle verfügbaren Bagger Verwendung finden. Dabei wird der Schwenkantrieb vorzugsweise als Teil der Traverse montiert sein und kann seinerseits mit entsprechend fernsteuerbaren Elektro- oder Hydraulikantrieben und Steuerungen des Baggers gekoppelt und somit vom Baggerfahrer von seinem Sitz aus ferngesteuert werden. Alternativ kann der Bagger oder Kran mit einem separaten, zwischen Traverse und Bagger gekoppeltem, Schwenkantrieb ausgestattet sein.The device according to the invention can be mounted according to the invention at the construction site on a commercial crane or excavator, preferably an already equipped with hydraulic drive mobile excavator. This saves investment costs when equipping the often available excavator with it. Rarely, however, could such a crane as a special crane equipped with a device according to the invention, all drives and parts of the device with a remote control, for example, for rotary motor, swinging the legs, moving the camera, extending or retracting the bolts of the holding device, can be operated. On the other hand, the device can be used simply as an attachment to an excavator available on every construction site. In this case, the pivot drive is preferably mounted as part of the traverse and in turn can be coupled with correspondingly remotely controlled electric or hydraulic drives and controls of the excavator and thus remotely controlled by the excavator driver from his seat. Alternatively, the excavator or crane may be equipped with a separate pivot drive coupled between the traverse and the excavator.

Die Vorrichtung 2 weist eine Traverse 20 auf, die mittels Koppeleinrichtung 21 mit einem nicht dargestellten Hydraulikbagger verbunden ist. Diese Einrichtung kann beispielsweise als ein Drehmotor für das Schwenken der Vorrichtung 2 um eine vertikale Achse mit Eingangs- und Ausgangswelle gestaltet sein. Quer zur Traverse 20 sind ein Querhaupt 23 für das Gabelende 12 der Y-Schwelle 1 und ein Querhaupt 23' für das Stabende 11 der Y-Schwelle 1 angeordnet und mit der Traverse 20 drehfest verbunden. Jedes Ende eines Querhauptes 23, 23' ist mit einem vertikal sich erstreckenden Schenkel 22, 22', 22", 22'" fest verbunden. An der Traverse 20 oder dem Querhaupt 23 können ein oder mehrere Schwerter 25 angebracht sein, die eine Führung der Vorrichtung 1 genau vertikal zu einem Stapel Y1, Y2 von Y-Stahlschwellen 1 erlauben. Außerdem kann die Traverse 20 oder ein Querhaupt 23, 23' oder ein Schenkel 22, 22', 22",22"' mit einer Kamera 24, 24' ausgestattet sein. Damit kann ein Bediener der Vorrichtung 1 gezielter operieren, wobei in der Regel eine nicht dargestellte Fernsteuerung zur Bedienung der Vorrichtung 1 verwendet werden kann, soweit nicht der Baggerfahrer von seinem Sitz aus operiert und dabei mit der Kamera auf die an den Schienen S1 und S2 markierten Schwellenpositionen erfasst.
Eine Halteeinrichtung H umfasst an jedem der Schenkel einen unteren Bolzen A in Ebene A und einen oberen Bolzen B in Ebene B. Die Bolzen sind zueinander beabstandet um das Maß des Abstandes der gestapelten Y-Schwellen 1, hier im Stapel Y1 bzw. im Stapel Y2 (
The
A holding device H comprises at each of the legs a lower bolt A in plane A and an upper bolt B in plane B. The bolts are spaced apart by the amount of the distance of the stacked Y-
Schritt 1: Zum Transport von einem Wagen zum Gleis werden die Bolzen A, B der Halteeinrichtungen H in zwei übereinander liegenden Ebenen A und B der Schenkel 22, 22', 22", 22'" ausgerückt; sie halten einen Stapel Y-Schwellen 1, hier durchnummeriert mit I , II, II, IV usw. und arretieren die Y-Schwelle I und II von unten.Step 1: For transport from a car to the track, the bolts A, B of the holding devices H are disengaged in two superimposed planes A and B of the
Schritt 2: Die erste Schwelle I, wird abgesetzt indem:
- die
Vorrichtung 2 mit dem Stapel Y1 mit Y-Schwellen auf das Schotterplanum P abgesenkt wird; die unterste Schwelle I steht dabei auf dem Schotter P auf; - der Bolzen A in Ebene A wird eingerückt (Pfeil) ;
- der Bolzen B in Ebene B bleibt ausgerückt (Pfeil);
- der Stapel Y1 mit restlichen Schwellen II -VI wird angehoben.
- the
device 2 with the stack Y1 with Y-thresholds is lowered onto the gravel surface P; the lowest threshold I stands on the gravel P; - the bolt A in plane A is engaged (arrow);
- the bolt B in level B remains disengaged (arrow);
- the stack Y1 with residual threshold II -VI is raised.
Bis zum erneuten Aufgreifen eines neuen Stapels Y2 Y-Schwellen wird der Bolzen A in Ebene A nicht mehr bewegt.Until a new stack of Y2 Y-sleepers is picked up again, the bolt A in level A is no longer moved.
Schritt 3: Die Vorrichtung 2 wurde um 180 ° gedreht wegen der Geometrie Y-Schwelle:Step 3: The
Schritt 4: Absetzen der nächsten Schwelle II:
- die
Vorrichtung 2 setztmit den Schenkeln 22, 22' auf dem Schotter-Planum P auf; - der Bolzen B der Ebene B wird eingerückt;
- der Stapel Y1 mit Y-Schwellen rutscht bis auf das Schotter-Planum P durch, dabei entsteht keine schlagartige Belastung der Vorrichtung 2, weil die Energie vom Schotterplanum P aufgefangen wird. Somit wird auch das
Material der Vorrichtung 2 geschont.
- the
device 2 sets with thelegs 22, 22 'on the ballast Planum P; - the B bolt B of the B level is engaged;
- the stack Y1 with Y-threshold slips through to the ballast planum P, there is no sudden loading of the
device 2, because the energy is absorbed by the gravel planum P. Thus, the material of thedevice 2 is spared.
Schritt 5: Der Bolzen B der Ebene B rückt wieder aus und hält somit die restlichen Y-Schwellen im Stapel Y1.
Die Vorrichtung 2 hebt ab, dreht um 180° und setzt erneut auf Schotter-Planum P auf, usw. bis alle Schwellen abgesetzt sind.Step 5: The level B bolt B exits again, thus keeping the remaining Y-thresholds in the stack Y1.
The
Schritt 6, nicht dargestellt: Ein neuer Stapel Y3 (nicht dargestellt) mit Schwellen ist zu laden:
- hierzu werden die Bolzen A, B der Ebenen A und B eingerückt;
- der Stapel Y3 Schwellen wird durch Absenken der Vorrichtung 2 über dem Stapel Y3 aufgenommen;
- dann rücken die Bolzen A, B der Ebene A und B wieder aus.
Der Vorgangkann ab Schritt 1 erneut beginnen.
- for this purpose, the bolts A, B of the planes A and B are indented;
- the stack Y3 sleepers is received by lowering the
device 2 above the stack Y3; - then the bolts A, B of plane A and B move out again.
The process can start again fromstep 1.
Eine Traverse mit Querhaupt 33 der Vorrichtung 3 ist mittels Koppeleinrichtung 31 mit dem nicht gezeigten Bagger verbunden.
Über zwei Schwenkgelenke 36 sind die Schenkel 32, 32' mit dem Querhaupt schwenkbeweglich verbunden. Ein antreibbarer Zylinder 35 kann über nicht sichtbare Kniehebel die Schenkel 32, 32' um den Winkel W einwärts um z.B. 15°, aber auch auswärts schwenken, spreizen gemäß Pfeil SP.
Zur Aufnahme eines Stapels Y-Schwellen 1 - die unterste ist mit I bezeichnet -, hier mit ihrer Gabelseite 12 gezeigt, werden die Schenkel 32, 32' senkrecht gestellt, die Vorrichtung 3 über den Stapel abgesenkt und sodann die Schenkel 32, 32' mit dem Zylinder einwärts geschwenkt um den Winkel W und solange Druck D ausgeübt, bis die unterste Schwelle I von den Schenkeln klemmend gehalten wird. Dabei kommen die Schwellen mit einer Kunststoffleiste 34 der Schenkel in Kontakt, die die Schwellen unter Reibschluss zusätzlich halten. Die Leiste 34 ist bei Verschleiß auswechselbar.
