Abstract
Description
Die Erfindung bezieht sich auf eine Einrichtung zum Verstellen und Verriegeln von beweglichen Weichenteilen mit einem von einer Stange gebildeten hydraulischen Kolben, welcher über Kopplungs- bzw. Verriegelungsglieder mit einer axial verschiebbaren Hülse für die Aufnahme der radial verschieblichen Kopplungs- bzw. Verriegelungsglieder zusammenwirkt, wobei die verschiebbare Hülse mit dem beweglichen Weichenteil gekoppelt ist, und mit einem außenliegenden, die Hülse und die Stange zumindest teilweise übergreifenden Rohr.The invention relates to a device for adjusting and locking movable switch parts with a piston formed by a hydraulic piston, which cooperates via coupling or locking members with an axially displaceable sleeve for receiving the radially displaceable coupling or locking members, wherein the slidable sleeve is coupled to the movable switch part, and with an outer, the sleeve and the rod at least partially cross-tube.
Einrichtungen zum Verriegeln der Endlagen von beweglichen Weichenteilen sind in unterschiedlicher Ausbildung bekannt geworden. Die EP 0 603 156 A1 zeigt und beschreibt hierbei eine Endlagensicherung von beweglichen Weichenteilen, und insbesondere einen Weichenverschluß, bei welchem in einem Rohr ein Bolzen bzw. eine Stange geführt wird, wobei die Stange und das Rohr axial verschieblich in einem Außenrohr gehalten sind. Das Rohr weist hierbei Durchbrechungen für in radialer Richtung verlagerbare Verriegelungsglieder auf, welche bei der bekannten Ausbildung von Kugeln oder Walzen gebildet wurden. Der Mantel der Stange weist gleichfalls in vorbestimmten axialen Abständen entsprechende Ausnehmungen auf, sodaß es gelingt, durch relative Verschiebung der Stange zum die Verriegelungsglieder tragenden Rohr diese Verriegelungsglieder entweder in eine auswärtige Verriegelungsposition zu verschieben, in welcher sie mit Anschlägen im Außenrohr zusammenwirken, oder einwärts zu verschieben, sodaß die Relativverschiebung von Rohr und Stange in axialer Richtung ermöglicht wird. Bei diesen bekannten Ausbildungen war das die Verriegelungsglieder tragende Rohr mit den zu verstellenden Weichenteilen gekoppelt. In Abwandlung dieser Ausbildung wurde in der WO 98/54041 eine Verschlußeinrichtung vorgeschlagen, bei welcher ein Hydraulikaggregat angekoppelt ist, die Verschlußeinheit selbst jedoch nicht Teil des hydraulischen Verstellelementes ist und in einem gesonderten, abgedichteten Gehäuse geführt ist. Um bei der Verstellung der Stange in der Folge auch eine Verstellung der beweglichen Weichenteile zu bewirken, muß über einen vorbestimmten axialen Verschiebeweg die die Verriegelungsglieder tragende Hülse bzw. das die Verriegelungsglieder tragende Rohr entsprechend von der Stange mitgenommen werden, wobei die Verschiebekräfte von den von Kugeln gebildeten Kupplungs- bzw. Verriegelungsgliedern zur Verschiebung der Hülse aufgenommen werden müssen. Zur Verbesserung der Verriegelungswirkung wurde bereits vorgeschlagen, an den Kugeln Ringsegmente zu lagern, sodaß in der Verriegelungslage die Kräfte nicht mehr als Linienpunktberührung der Kugel sondern als auf die Ringflächen der Verriegelungssegmente wirksame Kräfte aufgenommen werden können. In der Verriegelungslage war damit gewährleistet, daß die großen Verriegelungskräfte in der Größenordnung von 100 000 Newton an den entsprechenden Ringflächen sicher aufgenommen werden können.Means for locking the end positions of movable switch parts have become known in various forms. EP 0 603 156 A1 shows and describes a limit switch securing of movable switch parts, and in particular a switch lock, in which a bolt or a rod is guided in a tube, wherein the rod and the tube are held axially displaceably in an outer tube. The tube in this case has openings for displaceable in the radial direction locking members, which were formed in the known design of balls or rollers. The skirt of the rod also has corresponding recesses at predetermined axial intervals, so that it is possible to displace these locking members either by moving the rod relative to the locking members carrying tube into an outward locking position in which they cooperate with stops in the outer tube or inwardly move, so that the relative displacement of the tube and rod is made possible in the axial direction. In these known embodiments, the tube carrying the locking members was coupled to the switch parts to be adjusted. In a modification of this training, a closure device has been proposed in WO 98/54041, in which a hydraulic unit is coupled, the closure unit itself, however, not part of the hydraulic adjusting element is and is guided in a separate, sealed housing. In order to effect in the adjustment of the rod in the sequence and an adjustment of the movable switch parts, the locking members bearing sleeve and the locking members carrying pipe must be taken along by a predetermined axial displacement corresponding to the rod, the displacement forces of the balls formed coupling or locking members must be added to move the sleeve. To improve the locking effect has already been proposed to store ring segments on the balls, so that in the locking position, the forces can not be taken as a line point contact of the ball but as effective on the annular surfaces of the locking segments forces. In the locking position was thus ensured that the large locking forces in the order of 100 000 Newton can be safely absorbed on the corresponding annular surfaces.
Neben diesen Ausbildungen sind aus der AT 403 683 B und der AT 406 038 B unterschiedliche Ausgestaltungen einer Umstellhilfe zu entnehmen, bei welcher über einen Teilbereiches des Verschiebeweges eine entsprechend federnd ausgelegte Unterstützung der Verstellbewegung ermöglicht wurde. Zu diesem Zweck waren entweder die Verriegelungsglieder oder die die Verriegelungsglieder tragende Hülse über Federn abgestützt, sodaß je nach Position der jeweiligen Koppel- bzw. Verriegelungsglieder die Hülse über einen Teil des Verschiebewegs durch die Kraft der Feder unterstützt verschoben werden konnte. Bei derartigen Ausführungen ist die innenliegende Stange mit entsprechenden Kopplungsgliedern für die beweglichen Weichteile verbunden.In addition to these designs, AT 403 683 B and AT 406 038 B show different embodiments of a changeover aid, in which a corresponding resilient support of the adjustment movement was made possible over a partial region of the displacement path. For this purpose, either the locking members or the sleeve carrying the locking members were supported by springs, so that depending on the position of the respective coupling or locking members, the sleeve could be moved over part of the displacement supported by the force of the spring. In such embodiments, the inner rod is connected to corresponding coupling members for the movable soft parts.
Die Erfindung zielt nun darauf ab, eine Einrichtung zum Verstellen und Verriegeln von beweglichen Weichenteilen der eingangs genannten Art zu schaffen, welche besonders kompakt baut und eine verbesserte Verschleißsicherheit gewährleistet. Ausgehend von dem bekannten Prinzip, bei welchem in einem feststehenden Rohr zwei zueinander relativ verschiebliche Teile, nämlich wenigstens ein Rohr und eine Stange, geführt sind und die beweglichen Weichenteile mit dem Rohr gekoppelt sind, sollen erfindungsgemäß alle Elemente innerhalb des Außenrohres integriert werden können, wobei weiters die Möglichkeit einer kontinuierlichen Schmierung von dem Verschleiß unterworfenen Teilen erzielt werden soll. Weiters sollen die Koppelglieder, und insbesondere von Kugeln gebildete Koppelglieder effizient gegen Überlastung gesichert werden.The invention now aims to provide a device for adjusting and locking movable switch parts of the type mentioned, which is particularly compact and ensures improved wear resistance. Starting from the known principle, in which in a fixed Pipe two relatively mutually displaceable parts, namely at least one pipe and a rod, are guided and the movable switch parts are coupled to the pipe, according to the invention, all elements can be integrated within the outer tube, wherein further the possibility of continuous lubrication of the parts subject to wear should be achieved. Furthermore, the coupling members, and in particular formed by balls coupling members should be efficiently secured against overload.
Zur Lösung dieser Aufgabe besteht die Erfindung im wesentlichen darin, daß eine Hydraulikleitung an einer der Koppelstelle für den beweglichen Weichenteil abgewandten Stirnfläche der Hülse im außenliegenden Rohr mündet. Dadurch, daß eine Hydraulikleitung an einer der Koppelstelle für den beweglichen Weichenteil abgewandten Stirnfläche der Hülse im außenliegenden Rohr mündet, kann das außenliegende Rohr zur Gänze als Zylinder eines hydraulischen Antriebes gesichert werden, wobei sowohl die innenliegende Stange als auch die die Stange umgebende Hülse, welche die Koppelglieder und die Verriegelungsglieder trägt, mit Fluid beaufschlagt werden können. Auf diese Weise wird neben der Stirnfläche der Stange auch die Ringfläche der Hülse entsprechend mit Druck beaufschlagt, wobei nur ein geringer Teil der Umstellkraft über die Stirnfläche der innenliegenden Stange und ein vergleichsweise wesentlich höherer Teil der Verschiebekraft unmittelbar über die Stirnfläche des innenliegenden Rohres zur Wirkung gelangt. Für die Mitnahme des Rohres zum Zwecke der Verstellung des beweglichen Weichenteiles sind somit nicht mehr ausschließlich Kräfte wirksam, welche über die Koppelglieder bzw. Kugeln von der innenliegenden Stange auf das Rohr übertragen werden, sondern es werden zusätzliche Kräfte unmittelbar in das Rohr eingeleitet, sodaß die Kugeln bzw. Koppel- oder Verriegelungsglieder entsprechend entlastet werden. Auf diese Weise wird die Gefahr einer Überlastung und eines vorzeitigen Verschleißes wesentlich herabgesetzt, wobei dann, wenn als Fluidmedium beispielsweise Hydraulikflüssigkeit oder Öl verwendet wird, unmittelbar eine entsprechende Führung aller Teile in einem Ölbad erfolgt, sodaß ein mechanischer Verschleiß wesentlich herabgesetzt werden kann. Insgesamt gelingt es durch diese Anordnung, die Koppel- bzw. Verriegelungsglieder wesentlich zu entlasten und ein besonders hohes Maß an Betriebssicherheit zu gewährleisten.To solve this problem, the invention essentially consists in the fact that a hydraulic line opens at one of the coupling point for the movable switch part facing away from the end face of the sleeve in the outer tube. Characterized in that a hydraulic line opens at one of the coupling point for the movable switch part end face of the sleeve in the outer tube, the outer tube can be completely secured as a cylinder of a hydraulic drive, wherein both the inner rod and the sleeve surrounding the rod, which carries the coupling members and the locking members, can be acted upon with fluid. In this way, in addition to the end face of the rod and the annular surface of the sleeve is correspondingly pressurized, with only a small part of the Umstellkraft over the end face of the inner rod and a comparatively much higher part of the displacement force passes directly over the end face of the inner tube to the effect , For the entrainment of the tube for the purpose of adjustment of the movable switch part are thus not only exclusively effective forces which are transmitted via the coupling members or balls of the inner rod to the tube, but additional forces are introduced directly into the tube, so that the Spheres or coupling or locking members are relieved accordingly. In this way, the risk of overloading and premature wear is substantially reduced, in which case when hydraulic fluid or oil is used as fluid medium, for example, immediately a corresponding leadership of all parts is done in an oil bath, so that mechanical wear can be significantly reduced. Overall, it is possible by this arrangement to relieve the coupling or locking members significantly and to ensure a particularly high level of operational safety.
Prinzipiell können eine oder mehrere Verriegelungsebenen in jeder Umstelleinheit vorgesehen sein. Für eine Umstellvorrichtung eines beweglichen Herzstückes können derartige Einheiten unmittelbar miteinander verbunden werden, wobei die verschieblichen Innenrohre mit einer entsprechenden Koppeleinrichtung verbunden sind. Insgesamt gelingt es in diesem Falle, eine sehr starre, schwingungsarme Stellvorrichtung zu verwirklichen.In principle, one or more locking levels can be provided in each changeover unit. For a changeover device of a movable center piece such units can be connected directly to each other, wherein the displaceable inner tubes are connected to a corresponding coupling device. Overall, it is possible in this case to realize a very rigid, low-vibration actuator.
In bevorzugter Weise ist die erfindungsgemäße Ausbildung so getroffen, daß die Hülse dichtend im außenliegenden Rohr geführt ist, sodaß Leckölverluste weitestgehend vermieden werden können.Preferably, the inventive design is such that the sleeve is sealingly guided in the outer tube, so that leakage oil losses can be largely avoided.
Wie bei anderen Ausbildungen bereits an sich bekannt, ist die Ausbildung bevorzugt so getroffen, daß die Kopplungs- bzw. Verriegelungsglieder von Kugeln gebildet sind, welche mit von Ringsegmenten gebildeten Verriegelungsgliedern zusammenwirken. Während des Umstellvorganges werden, wie eingangs erwähnt, die Kugeln entsprechend entlastet, wobei in der Verriegelungslage die entsprechende Flächenberührung, wie sie von Ringsegmenten, welche in entsprechende Ausnehmungen des Außenrohres eintauchen, ausgebildet werden kann, gewährleistet werden kann.As already known per se in other embodiments, the design is preferably such that the coupling or locking members are formed by balls which cooperate with locking members formed by ring segments. During the changeover process, as mentioned above, the balls are relieved accordingly, in the locking position, the corresponding surface contact, as can be formed by ring segments, which dive into corresponding recesses of the outer tube, can be ensured.
Prinzipiell ist es bei derartigen Einrichtungen wünschenswert, entsprechende Kontroll- oder Schaltelemente in den Verstell- und Verriegelungsmechanismus zu integrieren, wobei auf diese Weise auch eine sichere Überwachung der jeweiligen Endstellung ermöglicht wird. Bevorzugt kann ein derartigen Schalt- oder Überwachungselement im Boden des Zylinderraumes untergebracht werden, wobei bei der erfindungsgemäßen Ausbildung zu berücksichtigen ist, daß dieser Boden des Zylinderraumes, in welchem sowohl die Stange als auch die Hülse als Kolben verfahrbar sind, vom Druckmedium beaufschlagt ist. Ein entsprechend hoher Arbeitsdruck kann daher prinzipiell bei konventionellen Stellgliedern bereits eine Verschiebung des Stellgliedes im Boden des Zylinders bewirken, wodurch Fehlanzeigen nicht ausgeschlossen werden könnten. Prinzipiell kann naturgemäß eine entgegen der Verschieberichtung des Stellgliedes des Schalters oder Schaltventiles wirksame Feder hinreichend stark dimensioniert sein, um dem Fluiddruck im Arbeitsraum standzuhalten. In solchen Fällen würde allerdings die Betätigung des Schalters oder Umschaltventils in der Endstellung hohe Kräfte erfordern. Gemäß einer bevorzugten Weiterbildung der erfindungsgemäßen Einrichtung ist die Ausbildung daher so getroffen, daß im Boden des den Hydraulikanschluß tragenden Arbeitszylinders der Stange und der Hülse ein Stössel axial verschieblich gelagert ist, wobei dieser Stössel bevorzugt als Differentialkolben ausgebildet ist. Bei Ausbildung des Stössels als Differentialkolben werden bei im Arbeitsraum unter Druck stehendem Fluid Verstellbewegungen des Stössels verhindert und die für die sichere Anzeige der Endlage erforderlichen Stellkräfte entsprechend reduziert. Mit Vorteil ist die Ausbildung hierbei so getroffen, daß der Stössel mit einem elektrischen Schalter und/oder einem Schaltventil zusammenwirkt.In principle, it is desirable in such devices to integrate appropriate control or switching elements in the adjustment and locking mechanism, in this way, a safe monitoring of the respective end position is made possible. Preferably, such a switching or monitoring element housed in the bottom of the cylinder chamber be taken into account in the inventive design that the bottom of the cylinder chamber, in which both the rod and the sleeve are moved as a piston, is acted upon by the pressure medium. Therefore, a correspondingly high working pressure can in principle already cause a displacement of the actuator in the bottom of the cylinder in conventional actuators, whereby false readings could not be excluded. In principle, an effective counter to the direction of displacement of the actuator of the switch or switching valve spring can be sufficiently large dimensioned to withstand the fluid pressure in the working space. In such cases, however, the operation of the switch or changeover valve in the end position would require high forces. According to a preferred embodiment of the device according to the invention, the training is therefore made so that in the bottom of the hydraulic connection bearing working cylinder of the rod and the sleeve, a plunger is mounted axially displaceable, said plunger is preferably designed as a differential piston. When the ram is designed as a differential piston, adjusting movements of the ram are prevented in the fluid under pressure in the working space and the adjusting forces necessary for the reliable indication of the end position are correspondingly reduced. Advantageously, the training is made here so that the plunger cooperates with an electrical switch and / or a switching valve.

Das innenliegende Rohr 5 weist Durchbrechungen 7 für die Aufnahme von Verriegelungs- bzw. Koppelgliedern 8 auf, wobei die innenliegende Stange 6 eine entsprechende Anschlagschulter 9 für die Kopplung mit den Kopplungs- und Verriegelungsglied 8 aufweist. Die Einrichtung 3 ist hierbei an den mit 10 schematisch angedeuteten Enden ortsfest festgelegt. Es ist weiters ein Hydraulikanschluß 11 ersichtlich, welcher in einen Arbeitsraum 12 mündet, wobei die entsprechenden Anschlüsse bei der Darstellung nach Fig.1 symmetrisch ausgelegt sind.In FIG. 1, 1 denotes a movable center piece, which is optionally displaced into contact with two
Bei der Darstellung nach Fig.1 ist das Herzstück 1 in seine rechte Endposition verschoben, wobei die Verriegelungsglieder 8 durch Auflaufen auf den entsprechend vollen Querschnitt der Stange 6 in entsprechende Verriegelungsnuten des außenliegenden Rohres 4 eingreifen, wodurch das innenliegende Rohr 5 gegen eine weitere Verschiebung gesichert ist und das Herzstück 1 gesichert in der Anlagestellung gehalten wird. Dies entspricht der in Fig.2 vergrößert dargestellten Position, in welcher auch erkennbar ist, daß die Koppel- und Verriegelungsglieder von innenliegenden Kugeln 13 und die Kugeln übergreifenden Ringsegmenten 14 gebildet sind, sodaß in der Verriegelungslage eine Flächenberührung der Ringsegmente mit den Flanken der Nut 15 ermöglicht wird. Das im Arbeitsraum 12 über die Anschlüsse 11 zugeführte Druckmedium beaufschlagt bei der Verstellbewegung in Richtung des Pfeiles 16 nicht nur die Stirnfläche 17 der Stange 6 sondern auch die als Ringfläche ausgebildete Stirnfläche 18 des innenliegenden Rohres 5.In the illustration of Figure 1, the core 1 is moved to its right end position, the
Im Boden des mit dem außenliegenden Rohres 4 verbundenen Zylinders, welcher mit 19 bezeichnet ist, befindet sich ein Stössel 20, welcher als Betätigungsglied für einen elektrischen Schalter 21 und/oder Schaltventil wirkt. Das Außenrohr 4 ist dichtend mit diesem Boden 19 verbunden, wobei bei der vergrößerten Darstellung in Fig.2 hier zusätzlich ein weiteres Flanschrohr 22 über einen Teilbereich der axialen Länge des Außenrohres 4 vorgesehen ist, welches mit entsprechenden Verschraubungen ausgestattet sein kann, um eine sichere Verankerung und einen dichtenden Anschluß des außenliegenden Rohres 4 an den Boden 19 zu gewährleisten. Das Betätigungsglied bzw. der Stössel 20 ist in der Darstellung nach Fig.3 vergrößert dargestellt, und es ist ersichtlich, daß eine axiale Bohrung 23 den Arbeitsraum 12 mit dem Federraum 24 des Stössels 20 verbindet. Der Stössel selbst ist über eine Feder 25 abgestützt und weist einen Kolben 26 auf, dessen federraumseitige Ringfläche von dem über den Arbeitsraum 12 und die axiale Bohrung 23 in den Federraum 24 austretenden Fluid entsprechend beaufschlagt wird, sodaß der Stössel 20 in seiner ausgefahrenen Position auch dann verbleibt, wenn im Arbeitsraum 12 ein entsprechend hoher Druck ansteigt. Der Stössel 20 wirkt wiederum mit dem Schalter 21 zusammen, wobei mit 27 entsprechende Entlüftungsbohrungen bezeichnet sind.In the bottom of the cylinder connected to the

Bei einem geteilten Außenrohr 4, wie es in Fig.2 dargestellt ist, ist eine weitere Dichtung 32 zwischen dem inneren Außenrohr 33 und dem äußeren Außenrohr 34 vorgesehen. Die Verriegelungsglieder 13 und 14 und die verstellbaren Backenbrücken können somit in einem Ölbad geführt werden, sodaß die Verschleiß- und Reibungskräfte wesentlich herabgesetzt werden.The
