Abstract

Disclosed is a drive unit comprising a positioning rod (2) which is connected to the switch blades and is movable between two final positions by means of a drive unit (1), e.g. a cylinder-piston arrangement. A mechanical lock (3) is provided that is effective in the final positions of the positioning rod (2). In order to obtain a great degree of safety, the mechanical lock (3) acts directly upon the positioning rod (2) while a catch (4) that is equipped with a separately controllable cylinder-piston arrangement (6) is supplied for said lock (3). The catch (4) blocks a movement of the lock in the direction of the unlocked position when the positioning rod (2) is in a final position.

Description

Technisches UmfeldTechnical environment

Die Erfindung bezieht sich auf ein Antriebssystem für eine Schienenweiche gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a drive system for a rail switch according to the preamble of claim 1.

Mit einem derartigen Antriebssystem ist es möglich, eine Weichenschiene eines Schienenabschnitts für Eisenbahnen von einer Stellung in eine andere Stellung zu bringen. Derzeit sind verschiedene Antriebssysteme wie mechanische Antriebe über einen Stellmotor und verschiedene Kurvenscheiben oder elektrohydraulische Antriebe bekannt.With such a drive system, it is possible to bring a switch rail of a rail section for railways from one position to another position. Currently, various drive systems such as mechanical drives via a servomotor and various cams or electro-hydraulic drives are known.

Dabei ist es auch bekannt (siehe z.B. die DE 3227203 A ), bei einem elektrohydraulischen Antrieb eine einfache Stellstangen-Verriegelung vorzusehen, die bei einer Verstellung der Stellstange über verschiedene mechanische Elemente wie Steuerkurven oder voreilende Steuernocken entriegelt wird. Dabei ergibt sich jedoch der Nachteil, dass es beim Auftreten von Vibrationen zu einer ungewollten Bewegung des Antriebs der Stellstange kommen kann, was in weiterer Folge auch zu einer Bewegung der über ein Kupplungssystem verbundenen Stellstange führen kann. Da die Entriegelungseinrichtungen über den Bewegungsablauf gesteuert sind, bleibt die Stellstange in ihrer Endstellung nicht mehr gesichert, wodurch sich die mit der Stellstange verbundene Weiche ebenfalls bewegen kann. Die bekannte Verriegelung funktioniert also nur dann zuverlässig, wenn der Antrieb in der geplanten Position verbleibt und nur auf die Weiche Kräfte wirken. Bei Kräften auf den Antrieb kann diese Art der Verriegelung versagen.It is also known (see eg the DE 3227203 A ), in an electro-hydraulic drive to provide a simple locking rod lock, which is unlocked in an adjustment of the control rod via various mechanical elements such as cams or leading control cam. However, this results in the disadvantage that it can come to the occurrence of vibration to an unwanted movement of the drive of the control rod, which can subsequently result in a movement of the connected via a coupling system control rod. Since the unlocking devices are controlled via the movement sequence, the adjusting rod is no longer secured in its end position, as a result of which the switch connected to the adjusting rod can likewise move. Thus, the known locking only works reliably when the drive remains in the planned position and only act on the soft forces. With forces on the drive, this type of locking can fail.

Offenbarung der ErfindungDisclosure of the invention Technisches ProblemTechnical problem

Ziel der Erfindung ist es, diese Nachteile zu vermeiden und ein Antriebssystem der eingangs erwähnten Art vorzuschlagen, bei dem eine sichere Verriegelung gewährleistet ist.The aim of the invention is to avoid these disadvantages and to propose a drive system of the type mentioned, in which a secure locking is ensured.

Technische LösungTechnical solution

Erfindungsgemäß wird dies durch die kennzeichnenden Merkmale des Anspruchs 1 erreicht.This is achieved by the characterizing features of claim 1 according to the invention.

Durch die vorgeschlagenen Maßnahmen ergibt sich der Vorteil, dass die Verriegelung erst dann aus der verriegelten Stellung bewegt werden kann, wenn die Sperre aus ihrer Sperrstellung durch den der Sperre zugeordneten Antrieb bewegt wurde. Allenfalls auftretende Vibrationen können daher nicht zu einer Entriegelung der Verriegelung führen, sodass eine mit einem erfindungsgemäßen Antriebssystem versehene Weiche auch in einem solchen Fall nicht aus ihrer jeweiligen Stellung gebracht werden kann.The proposed measures, there is the advantage that the lock can only be moved from the locked position when the lock has been moved from its blocking position by the drive associated with the lock. Any occurring vibrations therefore can not unlock the lock lead, so that provided with a drive system according to the invention switch can not be brought out of their respective position in such a case.

Durch die Merkmale des Anspruchs 2 ergibt sich der Vorteil, dass die Sperre nur in einer Endstellung der Stellstange wirksam werden kann. Sobald die Stellstange ein Stück bewegt wurde, hat der Rastvorsprung die Rastausnehmung verlassen, sodass die Sperre nicht mehr in die Sperrstellung zurückkehren kann. Es ist daher nicht notwendig, den Antrieb der Sperre während des gesamten Stellvorgangs zu betätigen, es genügt, dies zu Beginn des Stellvorgangs zu tun. Nur wenn sich die Stellstange in einer ihrer Endstellungen befindet, kann die Sperre in die Rastausnehmung der Stellstange einrasten und dabei mit ihrem Ansatz eine Bewegung der Verriegelung in Richtung deren entriegelter Stellung verhindern.Due to the features of claim 2, there is the advantage that the lock can be effective only in an end position of the control rod. Once the control rod has been moved a piece, the locking projection has left the recess, so that the lock can not return to the locked position. It is therefore not necessary to actuate the drive of the lock during the entire setting process, it is sufficient to do this at the beginning of the setting process. Only when the control rod is in one of its end positions, the lock can engage in the recess of the control rod, thereby preventing with their approach movement of the lock in the direction of its unlocked position.

Zur Steuerung der Verriegelung ist es vorteilhaft, die Merkmale des Anspruchs 3 vorzusehen. Auf diese Weise ist eine einfache Steuerung der Bewegung der Verriegelung sowie auch deren Blockierung in den Endstellungen der Stellstange möglich.To control the lock, it is advantageous to provide the features of claim 3. In this way, a simple control of the movement of the lock as well as their blocking in the end positions of the control rod is possible.

Durch die Merkmale des Anspruchs 4 ergibt sich eine sehr einfache Konstruktion für den Antrieb der Stellstange und der Verriegelung. Dabei ist durch das Spiel zwischen der Mitnehmeranordnung und dem Antrieb der Stellstange sichergestellt, dass bei in der Freigabestellung befindlicher Sperre die Verriegelung durch eine Bewegung des Antriebs gelöst werden kann, bevor die Stellstange bewegt wird. Das Spiel zwischen der Rastausnehmung des Verriegelungskörpers und dem Riegelkörper dient zum Toleranzausgleich, d.h. die Stellstange kann noch ein kleines Stück bewegt werden, nachdem die Sperre wirksam wurde. Durch die vorgeschlagenen Maßnahmen wird jeder Endstellung der Stellstange eine separate Sperre zugeordnet. Dadurch wird ein besonders hohes Maß an Sicherheit erreicht.Due to the features of claim 4 results in a very simple construction for driving the control rod and the lock. It is ensured by the game between the driver assembly and the drive of the control rod that when in the release position befindlicher lock the lock can be solved by a movement of the drive before the control rod is moved. The play between the locking recess of the locking body and the locking body is used for tolerance compensation, i. The control rod can still be moved a little bit after the lock has taken effect. The proposed measures each end position of the control rod is assigned a separate lock. This achieves a particularly high degree of safety.

In diesem Zusammenhang ist es zweckmäßig, die Merkmale des Anspruchs 5 vorzusehen.In this context, it is expedient to provide the features of claim 5.

Durch die Merkmale des Anspruchs 6 ergibt sich der Vorteil, dass eine Energiezufuhr zum Antrieb der Stellstange nur dann erfolgen kann, wenn die beiden Sperren sich in ihren Entriegelungsstellungen befinden, sodass eine Beschädigung der Sperren verhindert wird.Due to the features of claim 6, there is the advantage that a power supply to drive the control rod can only take place when the two locks are in their unlocked positions, so that damage to the locks is prevented.

Um eine ständige Information über den jeweiligen Status der Weiche und deren Verriegelungszustand zu ermöglichen, ist es vorteilhaft, die Merkmale des Anspruchs 7 vorzusehen. So kann man z.B. die Stellung des Signals auf "frei" davon abhängig machen, dass alle Weichen gesperrt sind.In order to allow continuous information about the respective status of the switch and its locking state, it is advantageous to provide the features of claim 7. So you can, for example make the position of the signal "free" dependent on the fact that all switches are locked.

Durch die Merkmale von Anspruch 8 ergibt sich ein hydraulischer Verschluss. Wie in der Figurenbeschreibung noch genauer ausgeführt werden wird, kann sich in diesem Fall der Antrieb nur bewegen, wenn zuvor die Zylinder-Kolbenanordnung ihren Anschlag erreicht hat. Zufällige Druckschwankungen im hydraulischen System bleiben unwirksam.Due to the features of claim 8 results in a hydraulic closure. As will be explained in more detail in the figure description, the drive can only move in this case, if previously the cylinder-piston assembly their Has reached the stop. Random pressure fluctuations in the hydraulic system remain ineffective.

Kurze Beschreibung von ZeichnungenShort description of drawings

Die Erfindung wird nun anhand der Zeichnung näher erläutert, die schematisch ein erfindungsgemäßes Antriebssystem für eine Weiche zeigt.The invention will now be explained in more detail with reference to the drawing, which schematically shows an inventive drive system for a switch.

Das erfindungsgemäße Antriebssystem weist einen Antrieb 1 in Form einer Zylinder-Kolbenanordnung auf, die mit einem unter Druck stehenden Fluid beaufschlagbar ist. Dabei ist die Kolbenstange 1.1 ortsfest gehalten und der Zylinder 1.4 ist auf dieser verschiebbar. Dabei ist dieser Zylinder 1.4 mit einem Mitnehmer 1.2 versehen, der in eine Ausnehmung 2.3 eines Verriegelungskörpers 2.1 mit Spiel eingreift.The drive system according to the invention has a drive 1 in the form of a cylinder-piston arrangement, which can be acted upon by a fluid under pressure. The piston rod 1.1 is held stationary and the cylinder 1.4 is slidable on this. In this case, this cylinder 1.4 is provided with a driver 1.2, which engages in a recess 2.3 of a locking body 2.1 with game.

Dieser Verriegelungskörper 2.1 ist fest an einer Stellstange 2 angeordnet und weist weiters zwei Rastausnehmungen 2.2 auf, die mit Riegeln 3.1 (z.B. in Form von Stiften) von Verriegelungen 3 zusammenwirken, die mit Spiel in die Rastausnehmungen 2.2 in deren Verriegelungsstellung eingreifen. Die Riegel 3.1 sind durch eine Feder nach unten vorgespannt.This locking body 2.1 is fixedly arranged on an adjusting rod 2 and further comprises two locking recesses 2.2, which cooperate with latches 3.1 (for example in the form of pins) of latches 3 which engage with play in the recesses 2.2 in their locking position. The bolt 3.1 are biased by a spring down.

Der Zylinder 1.4 des Antriebs 1 ist weiters mit einem Ansatz 1.5 fest verbunden, der mit einer Steuerkurve 1.3 versehen ist. An dieser liegt ein Tastorgan 3.3 der Verriegelung 3 an, wobei dieses als Rolle ausgebildete Tastorgan 3.3 an einem Arm 3.4 der Verriegelung 3 angeordnet ist. Dabei wirkt die andere Seite 3.2 des Arms 3.4 mit einem Ansatz 4.1 einer Sperre zusammen. Die Verriegelung 3 ist senkrecht zur Stellstange 2 bewegbar.The cylinder 1.4 of the drive 1 is further firmly connected to a shoulder 1.5, which is provided with a control cam 1.3. At this is a feeler 3.3 of the lock 3, which is designed as a roller feeler 3.3 is disposed on an arm 3.4 of the latch 3. In this case, the other side 3.2 of the arm 3.4 interacts with a shoulder 4.1 of a barrier. The lock 3 is perpendicular to the control rod 2 movable.

Die Sperre 4 weist im Wesentlichen eine Stange 4.6 auf, die mit einem Rastvorsprung 4.5 versehen ist, der - wenn sich die Stellstange 2 in der zugeordneten Endstellung befindet - in eine Rastausnehmung 4.7 der Stellstange 2 eingreift. Zu diesem Zweck ist er nach unten bzw. seitlich federbelastet, oder aber sein Gewicht ist ausreichend hoch. Dabei ist die Stange 4.6 mit einer (z.B. pneumatischen) Zylinder-Kolbenanordnung 6 nach oben anhebbar (bzw. seitlich verschiebbar).The lock 4 essentially has a rod 4.6, which is provided with a latching projection 4.5, which - when the control rod 2 is in the assigned end position - engages in a recess 4.7 of the control rod 2. For this purpose, it is spring-loaded downwards or laterally, or its weight is sufficiently high. In this case, the rod 4.6 is liftable (or displaced laterally) with a (for example pneumatic) cylinder-piston arrangement 6.

Besonders günstig ist es, die Zylinder-Kolbenanordnung 6 ebenfalls (so wie den Antrieb 1) hydraulisch zu betätigen und den Antrieb 1 über einen Druckminderer parallel zur Zylinder-Kolbenanordnung 6 anzuschließen. Wenn nun die Leitung beauf schlagt wird, bekommt zunächst nur die Zylinder-Kolbenanordnung 6 Druck und wird dadurch verschoben. Solange sich die Stange 4.6 bewegen kann, wird nur ein geringer Druck aufgebaut, der vom Druckminderer nicht an den Antrieb 1 weitergeleitet wird. Erst wenn die Stange 4.6 den Anschlag erreicht, wird ein Gegendruck aufgebaut. Sobald der Grenzwert des Druckminderers (z.B. 6 oder 8 bar) überschritten wird, leitet dieser den (entsprechend reduzierten) Druck an den Antrieb 1 weiter, der sich daraufhin entsprechend bewegt. Auf diese Weise ist rein hydraulisch sichergestellt, dass sich der Antrieb 1 nur bewegen kann, wenn die Stange 4.6 ihren Anschlag erreicht hat. Außerdem ist wegen des Druckminderers ausgeschlossen, dass sich der Antrieb 1 infolge unbeabsichtigter Druckschwankungen im hydraulischen System bewegt. (Derartige Druckschwankungen sind nie größer als z.B. 6 bar.)It is also particularly advantageous to hydraulically actuate the cylinder-piston arrangement 6 (such as the drive 1) and to connect the drive 1 via a pressure reducer parallel to the cylinder-piston arrangement 6. Now, if the line beauf beat, initially gets only the cylinder-piston assembly 6 pressure and is thereby displaced. As long as the rod 4.6 can move, only a low pressure is built up, which is not forwarded by the pressure reducer to the drive 1. Only when the rod 4.6 reaches the stop, a back pressure is built up. As soon as the limit value of the pressure reducer (eg 6 or 8 bar) is exceeded, it forwards the (correspondingly reduced) pressure to the drive 1, which moves then moved accordingly. In this way, it is ensured purely hydraulically that the drive 1 can only move when the rod 4.6 has reached its stop. In addition, due to the pressure reducer ruled out that the drive 1 moves due to unintentional pressure fluctuations in the hydraulic system. (Such pressure fluctuations are never greater than eg 6 bar.)

Von der Stange 4.6 steht ein Ansatz 4.1 ab, der mit dem Arm 3.2, 3.4 der Verriegelung 3 zusammenwirkt und in der dargestellten Sperrstellung eine Bewegung der linken Verriegelung 3 in deren Freigabestellung, in der der Riegel 3.1 außer Eingriff mit der Rastausnehmung 2.2 kommt, verhindert.From the rod 4.6 is an approach 4.1 from which cooperates with the arm 3.2, 3.4 of the lock 3 and in the illustrated blocking position, a movement of the left lock 3 in its release position, in which the bolt 3.1 is out of engagement with the recess 2.2, prevented ,

Die Stange 4.6 steuert über Ansätze 4.2 und 4.3 elektrische Schalter 5.1 und 5.2. Dabei steuert der Schalter 5.2 über nicht dargestellte Steuerorgane die Energiezufuhr bzw. die Zufuhr von unter Druck stehendem Fluid; nur wenn beide Schalter 5.2 betätigt sind, darf der Antrieb 1 betätigt werden. Der Schalter 5.2 ist mit einer nicht dargestellten Anzeigeeinrichtung oder mit Sicherheitseinrichtungen verbunden und signalisiert "Weiche verriegelt und gesperrt".The rod 4.6 controls via approaches 4.2 and 4.3 electrical switches 5.1 and 5.2. In this case, the switch controls 5.2 via control means, not shown, the power supply or the supply of pressurized fluid; only if both switches are operated 5.2, the drive 1 may be actuated. The switch 5.2 is connected to a display device, not shown, or with safety devices and signals "Soft locked and locked".

Um die Stellstange 2 von der dargestellten verriegelten Stellung in deren zweite, im dargestellten Fall rechte Stellung zu bringen, ist es erforderlich, die linke Zylinder-Kolbenanordnung 6 mit Druckmedium zu beaufschlagen, wodurch die Stange 4.6 der Sperre 4 angehoben (und deren Rastvorsprung 4.5 aus der Rastausnehmung 4.7 der Stellstange 2 gehoben) und der Ansatz 4.1 nach oben bewegt wird, wodurch eine Bewegung der Verriegelung 3 nach oben ermöglicht wird.In order to bring the actuating rod 2 from the illustrated locked position into its second, in the illustrated case right position, it is necessary to pressurize the left cylinder-piston assembly 6 with pressure medium, whereby the rod is raised 4.6 of the lock 4 (and its locking projection 4.5 off the locking recess 4.7 of the control rod 2 lifted) and the approach 4.1 is moved upward, whereby a movement of the lock 3 is made possible upwards.

Gleichzeitig gibt der Schalter 5.2 ein Signal und die Zufuhr von unter Druck stehendem Fluid zum Antrieb 1 frei. Dadurch beginnt sich der Zylinder 1.4 nach rechts zu bewegen. Dadurch bewegt sich auch der Ansatz 1.5, der die Steuerkurve 1.3 trägt, wodurch das Tastorgan 3.3 angehoben und dadurch der Riegel 3.1 aus der Rastausnehmung 2.2 des Verriegelungskörpers 2.1 gehoben wird. Dadurch ist die Verriegelung der Stellstange 2 gelöst, und der Verriegelungskörper 2.1 wird vom Mitnehmer 1.2 des Zylinders 1.4 mitgenommen, sobald dieser das Spiel zwischen dem Mitnehmer 1.2 und der Begrenzung der Ausnehmung 2.3 durchlaufen hat. Da der Verriegelungskörper 2.1 mit der Stellstange 2 fest verbunden ist, wird dadurch auch die Stellstange 2 bewegt.At the same time, the switch 5.2 releases a signal and the supply of fluid under pressure to the drive 1. As a result, the cylinder begins to move 1.4 to the right. As a result, also moves the approach 1.5, which carries the cam 1.3, whereby the feeler organ 3.3 is raised and thereby the bolt 3.1 is lifted from the locking recess 2.2 of the locking body 2.1. As a result, the locking of the control rod 2 is released, and the locking body 2.1 is taken from the driver 1.2 of the cylinder 1.4 as soon as it has passed through the game between the driver 1.2 and the boundary of the recess 2.3. Since the locking body 2.1 is firmly connected to the control rod 2, thereby also the control rod 2 is moved.

Nachdem der Verriegelungskörper 2.1 den Riegel 3.1 der rechten Verriegelung 3 erreicht hat, läuft dieser auf der Auflauffläche 2.4 auf und wird dadurch angehoben, was ohne weiters erfolgen kann, da der Rastvorsprung 4.5 der rechten Sperre 4 auf der Stellstange 2 aufliegt und daher angehoben ist. Sobald die rechte Rastausnehmung 2.2 des Verriegelungskörpers 2.1 erreicht ist, sinkt der Riegel 3.1 in diese ein. Danach hat dann die Stellstange 2 ihre rechte Endstellung erreicht und der Rastvorsprung 4.5 sinkt in die Rastausnehmung 4.7 der Stellstange 2 ein, wodurch der Ansatz 4.1 der rechten Sperre 4 zur Anlage an dem Arm 3.2, 3.4 der rechten Verriegelung 3 kommt, wodurch deren Bewegung nach oben verhindert wird und die Stellstange 2 sicher verriegelt bleibt.After the locking body has reached 2.1 the latch 3.1 of the right lock 3, this runs on the ramp surface 2.4 and is thereby raised, which can be done without further, since the locking projection 4.5 of the right lock 4 rests on the control rod 2 and is therefore raised. As soon as the right-hand recess 2.2 of the locking body 2.1 has been reached, the bolt 3.1 drops into it. Thereafter, the control rod 2 has reached its right end position and the locking projection 4.5 drops into the recess 4.7 of the control rod 2, whereby the approach 4.1 the right Barrier 4 to rest on the arm 3.2, 3.4 of the right lock 3 comes, whereby their movement is prevented upwards and the control rod 2 remains securely locked.

Dabei kommt es auch zur Betätigung der Schalter 5.1 und 5.2 der rechten Sperre 4, die dadurch eine sichere Verriegelung an die Weichenüberwachung melden.It also comes to the operation of the switches 5.1 and 5.2 of the right lock 4, which thereby report a secure locking to the points monitoring.
