Definitions
- the invention relates to a device for elongating a, a coupling lever having screw coupling between two railway vehicles, with a frame, with at least one driver for the coupling pivot, provided with a frame between driver and carrier guide having a trained for circulating the screw clutch guide rail, and with a drive connected to the cam guide for moving the cam along the track of the cam track.
- the invention is therefore based on the task of structurally simplifying a device for elongating a screw coupling of the type described and also to increase their stability.
- the invention solves this problem by the fact that the cam guide has an open sprocket, on the outside of a toothing for coupling with the drive and the inside of the driver is provided, wherein the sprocket opening of the sprocket in their width for introducing and removing the screw in or is formed from the sprocket.
- the driver guide has an open toothed ring, wherein the toothed rim opening of the toothed rim is designed to insert and remove the screw coupling in or out of the ring gear
- the driver guide can be positioned around the screw coupling-without any parts of the device having to be positioned relative to one another to be placed. It can therefore be omitted the relatively complex measure to adjust and close ring halves to each other, as is required in the prior art.
- the constructive effort on the device is considerably reduced.
- the constructive effort can be further reduced if externally a toothing for coupling with the drive and inside the driver are provided on the open sprocket.
- Such an embodiment of the device in the region of the toothed rim can additionally ensure reliable guidance of the driver about the screw coupling. According to the invention thus a structurally simple, yet very stable device for elongating a screw is created.
- the cam guide may have two oppositely-oriented drivers, whereby an orientation-independent device can be created.
- the driver guide has at least one bearing roller which, mounted on the frame, supports the sprocket on the inside, then the sprocket can be rotated by any desired angle - and in the course of this always remain supported on the driver guide. A particularly flexible and reliable device is thus guaranteed.
- the device can be made even more reliable in its function when the bearing roller rolls on rolling surfaces of the cam guide for supporting the ring gear.
- the drive has at least one drive pinion, which engages fixedly on the frame in the toothing of the ring gear and thus outsides the ring gear, a secure mounting and also a simple, stable drive of the ring gear can take place in a structurally simple manner.
- a plurality of drive pinions are provided, they can advantageously be positioned so that a drive of the ring gear in each angular position is possible and dead centers in the drive can be avoided. A device increased in its reliability can be created in this way.
- the stability of the device can be further increased if the frame has two parallel, U-shaped frame parts, between which the driver guide is arranged.
- a particularly stable mounting of the ring gear can be achieved, whereby the driver guide can remove high loads stable.
- the width of the frame opening and the width of the sprocket opening are substantially the same, a simple and error-free positioning of the device can be ensured which makes their use easy and safe to handle.
- a more reliable device for elongating a screw coupling can be provided if the device has a device with at least one lever for aligning the coupling swivel. If the lever is also rotatably mounted about an axis of rotation extending normal to the longitudinal axis of the screw coupling, the device can align the coupling swivel in the direction of the driver of the device. Due to the correct alignment of the coupling swivel, the device can reliably make a screw coupling reliably independent of the position of the coupling swivel.
- a device for aligning the coupling swivel is provided before and after the driver guide, a device for elongating can be provided which can reliably align the coupling slider in all possible positions and directions.
- the reliability of the device can be further increased if the device has two mutually laterally offset levers which are rotatably mounted on the same axis of rotation opposite curved. Clutch handle of all possible configurations and shapes can be aligned reliably.
- a device 1 for elongating a screw coupling 2 is shown.
- the screw coupling 2 - which is arranged, for example, between two railway vehicles - has a coupling pivot 3 for screwing on or for making the screw coupling 2 longer.
- the device 1, 101 comprises a frame 4, on which at least one driver 5 for the coupling pivot 3 is mounted via a driver guide 6.
- the driver guide 6 is provided between the frame 4 and driver 5 - in the representational example between these also arranged, but this need not necessarily be the case.
- the driver guide 6 forms a guideway 7 for the driver 5, based on which the driver 5, the screw coupling 2 can rotate. In the illustrated variant, there is a circular orbit.
- a drive 8 is connected to the driver guide 6 in order to move the carrier 5 along the guideway 7 - in the illustrated variant circular.
- the driver guide 6 may have two oppositely oriented driver 5, whereby the device 1, 101 can be made independent of the orientation of the screw coupling 2. The screwing of the screw coupling 2 can therefore take place by moving the coupling swivel 3 both counterclockwise and clockwise.
- this invention has an open sprocket 9.
- the toothing 10 of the ring gear 9 is on the outside for coupling with the drive 8, while the driver 5 is provided on the inside.
- the outer toothing 10 on the outside of the ring gear 9 can drive-connected and fixed to the frame 4 drive pinion 15 engage with a motor 14 - which not only a simple drive, but also a stable outside storage of the ring gear 9 are ensured. In this way, so the driver can be reliably moved around the screw coupling.
- the width of the sprocket opening 11 of the ring gear 9 is also dimensioned so that the screw coupling 2 can be easily inserted into the sprocket 9 and removed from it.
- the device 1, 101 is designed to be particularly easy to handle - among other things, since none of their parts must be positioned to each other.
- the cam guide 6 has a plurality of mounted on the frame 4 and rotatably mounted bearing rollers 12 which rotatably support the sprocket 9 on its inside.
- the ring gear 9 forms a rolling surface 13 on the inside, on which the bearing rollers 12 roll for the storage of the ring gear 9. Such stability and reliability of the device 1, 101 are increased.
- the frame 4 two parallel arranged, U-shaped frame members 16, which have the frame opening 17 to the bottom of the frame 4 out - the frame members 16 are therefore arranged congruent.
- the driver guide 6 is mounted between the U-shaped frame parts 16.
- the widths of frame opening 17 and sprocket opening 11 are substantially equal. In this way, a simple and disability-free insertion of the screw coupling 2 into the device 1, 101 by the frame or ring gear opening 17, 11 are made possible.
- Fig. 3 shows a device 101 for elongating a screw coupling 2 according to the in Fig. 1 and Fig. 2 features shown.
- the device 101 in each case along the longitudinal axis of the screw coupling 2 before and after the driver guide 6, a device 18 for aligning the coupling pivot 3.
- the device 18 has at least one lever 19, which is rotatably mounted about a normal to the longitudinal axis of the screw coupling 2 extending axis of rotation 20.
- two levers 19 are arranged in the device 18, which are mounted on the common axis of rotation 20, but have an opposite curvature.
- the levers 19 are thereby driven independently of the drive 8 of the device 101 via corresponding motors 21.
- the device 18 may also have a plurality of motors 21, each lever 19 being driven by its own motor, so that the levers 19 can be moved independently of each other, which has not been shown in detail in the figures.
- the device 18 has for attachment to the frame 4 of the device 101 on an L-shaped mounting frame 22, which positions the device 18 relative to the screw coupling 2 such that a reliable alignment of the coupling pivot 3 is made possible.

Description
Die Erfindung betrifft eine Vorrichtung zum Langmachen einer, einen Kupplungsschwengel aufweisenden Schraubenkupplung zwischen zwei Eisenbahnfahrzeugen, mit einem Gestell, mit zumindest einem Mitnehmer für den Kupplungsschwengel, mit einer zwischen Gestell und Mitnehmer vorgesehenen Mitnehmerführung, die eine zum Umlaufen der Schraubenkupplung ausgebildete Führungsbahn aufweist, und mit einem Antrieb, welcher mit der Mitnehmerführung verbunden ist, um den Mitnehmer entlang der Führungsbahn der Mitnehmerführung zu bewegen.The invention relates to a device for elongating a, a coupling lever having screw coupling between two railway vehicles, with a frame, with at least one driver for the coupling pivot, provided with a frame between driver and carrier guide having a trained for circulating the screw clutch guide rail, and with a drive connected to the cam guide for moving the cam along the track of the cam track.
Aus dem Stand der Technik (
Die Erfindung hat sich daher die Aufgabe gestellt, eine Vorrichtung zum Langmachen einer Schraubenkupplung der eingangs geschilderten Art konstruktiv zu vereinfachen und auch in ihrer Standfestigkeit zu erhöhen.The invention is therefore based on the task of structurally simplifying a device for elongating a screw coupling of the type described and also to increase their stability.
Die Erfindung löst die gestellte Aufgabe dadurch, dass die Mitnehmerführung einen offenen Zahnkranz aufweist, an dem außenliegend eine Verzahnung zur Kopplung mit dem Antrieb und innenliegend der Mitnehmer vorgesehen ist, wobei die Zahnkranzöffnung des Zahnkranzes in ihrer Weite zum Einbringen und Entfernen der Schraubenkupplung in bzw. aus dem Zahnkranz ausgebildet ist.The invention solves this problem by the fact that the cam guide has an open sprocket, on the outside of a toothing for coupling with the drive and the inside of the driver is provided, wherein the sprocket opening of the sprocket in their width for introducing and removing the screw in or is formed from the sprocket.
Weist die Mitnehmerführung einen offenen Zahnkranz auf, wobei die Zahnkranzöffnung des Zahnkranzes in ihrer Weite zum Einbringen und Entfernen der Schraubenkupplung in bzw. aus dem Zahnkranz ausgebildet ist, kann die Mitnehmerführung - ohne dass irgendwelche Teile der Vorrichtung zueinander positioniert werden müssen -, um die Schraubenkupplung platziert werden. Es kann daher die vergleichsweise aufwändige Maßnahme unterlassen werden, Ringhälften zueinander zu justieren und zu schließen, wie dies beim Stand der Technik erforderlich ist. Somit ist nicht nur die Handhabung, sondern auch der konstruktive Aufwand an der Vorrichtung erheblich reduzierbar.
Der konstruktive Aufwand kann sich weiter verringern, wenn am offenen Zahnkranz außenliegend eine Verzahnung zur Kopplung mit dem Antrieb und innenliegend der Mitnehmer vorgesehen sind. Eine derartige Ausführung der Vorrichtung im Bereich des Zahnkranzes kann zusätzlich auch eine zuverlässige Führung des Mitnehmers um die Schraubenkupplung sicherstellen.
Erfindungsgemäß ist somit eine konstruktiv einfache, aber dennoch besonders standfeste Vorrichtung zum Langmachen einer Schraubenkupplung geschaffen.If the driver guide has an open toothed ring, wherein the toothed rim opening of the toothed rim is designed to insert and remove the screw coupling in or out of the ring gear, the driver guide can be positioned around the screw coupling-without any parts of the device having to be positioned relative to one another to be placed. It can therefore be omitted the relatively complex measure to adjust and close ring halves to each other, as is required in the prior art. Thus, not only the handling, but also the design effort on the device is considerably reduced.
The constructive effort can be further reduced if externally a toothing for coupling with the drive and inside the driver are provided on the open sprocket. Such an embodiment of the device in the region of the toothed rim can additionally ensure reliable guidance of the driver about the screw coupling.
According to the invention thus a structurally simple, yet very stable device for elongating a screw is created.
Im Allgemeinen wird festgehalten, dass die Mitnehmerführung zwei gegengesetzt orientierte Mitnehmer aufweisen kann, wodurch eine orientierungsunabhängige Vorrichtung geschaffen werden kann.In general, it is noted that the cam guide may have two oppositely-oriented drivers, whereby an orientation-independent device can be created.
Weist die Mitnehmerführung mindestens eine Lagerrolle auf, die am Gestell befestigt den Zahnkranz innenliegend lagert, so kann der Zahnkranz um beliebige Winkel rotiert werden - und im Zuge dessen stets an der Mitnehmerführung gelagert bleiben. Eine besonders flexibel einsetzbare und zuverlässige Vorrichtung ist damit gewährleistbar.If the driver guide has at least one bearing roller which, mounted on the frame, supports the sprocket on the inside, then the sprocket can be rotated by any desired angle - and in the course of this always remain supported on the driver guide. A particularly flexible and reliable device is thus guaranteed.
Die Vorrichtung kann in ihrer Funktion noch zuverlässiger gestaltet werden, wenn die Lagerrolle an Walzflächen der Mitnehmerführung zur Lagerung des Zahnkranzes abwälzt.The device can be made even more reliable in its function when the bearing roller rolls on rolling surfaces of the cam guide for supporting the ring gear.
Weist der Antrieb mindestens ein Antriebsritzel auf, das am Gestell befestigt in die Verzahnung des Zahnkranzes eingreift und damit den Zahnkranz außenliegend lagert, können auf konstruktiv einfache Weise zugleich eine sichere Lagerung und auch ein einfacher, standfester Antrieb des Zahnkranzes erfolgen. Insbesondere, wenn mehrere Antriebsritzel vorgesehen sind, können diese vorteilhafterweise derart positioniert werden, dass ein Antrieb des Zahnkranzes in jeder Winkelstellung möglich ist und Totpunkte im Antrieb vermieden werden. Eine in ihrer Zuverlässigkeit erhöhte Vorrichtung kann derart geschaffen werden.If the drive has at least one drive pinion, which engages fixedly on the frame in the toothing of the ring gear and thus outsides the ring gear, a secure mounting and also a simple, stable drive of the ring gear can take place in a structurally simple manner. In particular, if a plurality of drive pinions are provided, they can advantageously be positioned so that a drive of the ring gear in each angular position is possible and dead centers in the drive can be avoided. A device increased in its reliability can be created in this way.
Die Standfestigkeit der Vorrichtung ist weiter erhöhbar, wenn das Gestell zwei parallel angeordnete, u-förmig Rahmenteile aufweist, zwischen denen die Mitnehmerführung angeordnet ist. Dadurch kann eine besonders stabile Lagerung des Zahnkranzes erreicht werden, wodurch die Mitnehmerführung hohe Belastungen standfest abtragen kann. Im Speziellen ist es dadurch möglich, beim Einwirken großer Kräfte - etwa beim Aufschrauben einer Schraubenkupplung - eine Verwindung der erfindungsgemäßen Vorrichtung zu vermeiden, wodurch deren fehlerfreie Betrieb gewährleistbar ist.The stability of the device can be further increased if the frame has two parallel, U-shaped frame parts, between which the driver guide is arranged. As a result, a particularly stable mounting of the ring gear can be achieved, whereby the driver guide can remove high loads stable. In particular, it is thereby possible to avoid distortion of the device according to the invention when large forces act, for example when screwing on a screw coupling, as a result of which error-free operation can be ensured.
Sind die Weite der Gestellöffnung und die Weite der Zahnkranzöffnung im Wesentlichen gleich, kann ein einfaches und fehlerfreies Positionieren der Vorrichtung sichergestellt werden, wodurch deren Einsatz leicht und sicher handhabbar gestaltet werden kann.If the width of the frame opening and the width of the sprocket opening are substantially the same, a simple and error-free positioning of the device can be ensured which makes their use easy and safe to handle.
Eine zuverlässigere Vorrichtung zum Langmachen einer Schraubenkupplung kann geschaffen werden, wenn die Vorrichtung eine Einrichtung mit mindestens einem Hebel zum Ausrichten des Kupplungsschwengels aufweist. Ist der Hebel zudem um eine normal zur Längssachse der Schraubenkupplung verlaufende Drehachse drehbar gelagert, so kann durch die Einrichtung eine Ausrichtung des Kupplungsschwengels in Richtung des Mitnehmers der Vorrichtung erfolgen. Durch das korrekte Ausrichten des Kupplungsschwengels kann die Vorrichtung dabei unabhängig von der Lage des Kupplungsschwengels eine Schraubenkupplung zuverlässig langmachen.A more reliable device for elongating a screw coupling can be provided if the device has a device with at least one lever for aligning the coupling swivel. If the lever is also rotatably mounted about an axis of rotation extending normal to the longitudinal axis of the screw coupling, the device can align the coupling swivel in the direction of the driver of the device. Due to the correct alignment of the coupling swivel, the device can reliably make a screw coupling reliably independent of the position of the coupling swivel.
Ist vor und nach der Mitnehmerführung je eine Einrichtung zum Ausrichten des Kupplungsschwengels vorgesehen, so kann eine Vorrichtung zum Langmachen geschaffen werden, die Kupplungsschwengel in allen möglichen Lagen und Richtungen zuverlässig ausrichten kann.If a device for aligning the coupling swivel is provided before and after the driver guide, a device for elongating can be provided which can reliably align the coupling slider in all possible positions and directions.
Die Zuverlässigkeit der Vorrichtung kann weiter erhöht werden, wenn die Einrichtung zwei seitlich zueinander versetzte Hebel aufweist, die an derselben Drehachse drehbar gelagert entgegengesetzt gekrümmt verlaufen. Kupplungsschwengel aller möglichen Ausgestaltungen und Formen können dadurch zuverlässig ausgerichtet werden.The reliability of the device can be further increased if the device has two mutually laterally offset levers which are rotatably mounted on the same axis of rotation opposite curved. Clutch handle of all possible configurations and shapes can be aligned reliably.

Die Mitnehmerführung 6 bildet eine Führungsbahn 7 für den Mitnehmer 5 aus, anhand welcher der Mitnehmer 5 die Schraubenkupplung 2 umlaufen kann.
