  • a machine element or hole or recess or groove or limit or stop surface on the guide body is referred to as engagement here with a locking surface which is transverse to the sliding direction and interacts positively with the locking end 22 of the locking bolt in its socket wrench.
  • the object of the invention is to design a locking device according to the preamble in such a way that a sliding body can be fixed positively on or on its guide body without having to take steps which are attached to the sliding body and / or guide body from the outside which the Increase structural dimensions or which hinder the handling, operation and function of the sliding body and / or guide body.
  • This task arises, for example, and in particular on a turnout drive for the turnout of a railroad track, which is connected to the turnout tongues of the turnout for shifting into one of the end positions - referred to as contact positions on the turnout - by an actuating rod that is axially displaceable perpendicular to the railway track and which is each of the end positions / contact positions by means of a stationary blocking device can be determined and must also be determined for security.

  • This switch has the disadvantage that it is not "blunt", which means that it can be opened in the opposite direction. Either the switch has to be adjusted for driving in the opposite direction or devices have to be provided to break the positive connection between the adjacent tongue and the track, for example to release a clamping. These devices are to be installed in addition to the point machine and also to be accommodated locally.

  • the form fit is canceled and the sliding body can be moved more or less freely on the guide body in the sliding direction.
  • the engagement (12) of the guide body (4) is designed on both sides as a conical hole or groove with tapered flanks 30, so that the locking bolt moves with every relative movement of the guide body (4) and sliding body (2) is driven into its neutral position (10).
  • the invention also solves the problem of positively securing a movable body in an end position between two stops, but allowing the body to move freely out of the end position without breaking the interlock in the event of a particularly sudden external force.
  • This situation occurs especially in point machines when a form-fitting and fixed point is driven over from behind without actuating the point machine, i.e. is driven on.
  • the sliding body is moved into the end position by driving the guide body with a force-fit connection with the sliding body and actuating the socket wrench in such a way that the locking pin is driven out into its locking position. Since the guide body is now fixed in a form-fitting manner, there is a form-fitting flow of force from the sliding body to the guide body.
  • the socket wrench By moving the socket wrench in the other direction by means of external force and then driving the locking pin into its neutral position, the positive locking is canceled and the sliding body can be pulled out of the end position by the socket wrench.
  • This invention is applied according to claim 5 to a point machine.
  • the locking key and the locking device according to one of the preceding claims are doubled by mirroring, so that the socket wrenches are mirror-inverted at the ends and exercise the same functions in opposite directions in one and the other sliding body.
  • the socket wrenches 13L and 13R are connected by a central body and can be moved and driven in both insertion directions and sliding directions.
  • the central body is connected to the guide body 4 in a force-locking manner. This is movably guided parallel to the direction of movement of the sliding body and equipped with a linear drive, for example a rack 24 aligned in the sliding direction.
  • the rack is geared to a drive motor.
  • the guide body 4 is therefore movable between the end positions of the switch tongues and in each of the end positions is positively fixed by a locking tongue 26 of a blocking device in such a way that the switch tongue, which is in a form-fitting manner on the track, is positively locked in the opposite direction via the sliding body connected to it and the blocking bolt guided in it is held with the guide body.
  • the form fit between the locking pin and the guide body is established in that the socket wrench dips far into the insertion end of the sliding body, thereby driving out the locking pin and holding it in the locking position 11 there by the locking surface 19.
  • the active edges / active surfaces in the pockets and on the locking pins which are aligned at 45 °, are inclined so that the locking pin is driven out into its locking position when the socket wrench is immersed to a greater depth and is drawn into its neutral position at a lower immersion depth.
  • the other sliding body connected to the non-abutting switch tongue remains freely movable for a dead path, which is defined by the free space of the locking bolt, which is guided straight on this sliding body, in its pocket of the socket wrench.
  • the switch tongue that is not in contact can therefore move over this dead path when the switch is opened bluntly.
  • the locking bolt which is straight in its sliding body, engages behind the pushing edge 16 in the socket wrench's pocket after the dead travel, pulls it out of the insertion end of the other positively fixed sliding body, thereby pulling the locking surface 19 under the locking bolt, and pulls the locking bolt by sliding off the driving surface 20 back into the contour of the sliding body and thereby releases the positive locking of the non-abutting switch tongue.

  • the relative position of the socket wrench 13 in the sliding body is such that (see Fig.1B and 2 B ) the locking pin 7 is driven out into its locking position 11 by the interaction of the expulsion edge 17 on the socket wrench 13 and the expulsion surface 18 inclined at about 45 ° to the sliding direction and straight guidance of the locking pin on the front of the locking pin 7, each seen in the direction of movement of the sliding body 2.
  • the locking pin in Fig.1 is a short plate of sufficient thickness extending perpendicular to the plane of the drawing; it must be able to withstand the bending and shear forces, which occur in the slideway during the relative movement of the guide and sliding bodies. It is bent by about 45 ° at about half its height.
  • the rear side of the bent area, which faces the expulsion edge 17, forms the expulsion surface 18, which interacts with the expulsion edge 18 and forms the expulsion-effective pairing.

Description

Die Erfindung betrifft eine Verriegelungseinrichtung an zwei relativ zu einander an einer Führungsbahn gleitend beweglichen Körpern nach dem Oberbegriff des Anspruch 1, wie in der DE102013009116A1 beschrieben. Von diesen Körpern gleitet der eine, der Gleitkörper, relativ zu dem anderen auf der Gleitbahn des anderen, des Führungskörpers. In Gleitrichtung ist der Gleitkörper beweglich bis zu einer Endlage. Dort wird er mit dem Führungskörper durch die Verriegelungseinrichtung in seiner Gleitrichtung und/oder gegen seine Gleitrichtung verriegelt und formschlüssig verbunden.The invention relates to a locking device on two bodies which can slide relative to one another on a guide track according to the preamble of claim 1, as in FIG DE102013009116A1 described. One of these bodies, the sliding body, slides relative to the other on the sliding path of the other, the guide body. In the sliding direction, the sliding body can be moved up to an end position. There it is locked and positively connected to the guide body by the locking device in its sliding direction and / or against its sliding direction.

Es ist eine gängige Technik, dass die Verriegelungseinrichtung einen Sperrbolzen aufweist, welcher in dem Gleitkörper quer zur Führungsbahn in einer Geradführung geführt und in Austreibrichtung beweglich ist zwischen einer Neutralstellung, in welcher er in die Kontur des Gleitkörpers im Bereich der Führungsbahn zurücktritt, und einer Sperrstellung, in welcher das Sperrende 22 des Sperrbolzens mit einem Eingriff 12 des Führungskörpers die Gleitrichtung 5 formschlüssig sperrend zusammenwirkt. Als Eingriff wird hier ein Maschinenelement oder Loch oder Aussparung oder Nut oder Begrenzungs- oder Anschlagfläche an dem Führungskörper bezeichnet mit einer Sperrfläche, welche quer zur Gleitrichtung liegt und mit dem Sperrende 22 des Sperrbolzens in dessen Steckschlüssel formschlüssig zusammenwirkt.It is a common technique that the locking device has a locking bolt, which is guided in the sliding body transversely to the guideway in a straight line and is movable in the expulsion direction between a neutral position, in which it steps back into the contour of the sliding body in the area of the guideway, and a locking position , in which the locking end 22 of the locking pin interacts with an engagement 12 of the guide body in a form-fitting locking manner in the sliding direction 5. A machine element or hole or recess or groove or limit or stop surface on the guide body is referred to as engagement here with a locking surface which is transverse to the sliding direction and interacts positively with the locking end 22 of the locking bolt in its socket wrench.

Man denke z.B. an eine durch einen Riegel verschließbare Tür.Think, for example, of a door that can be locked with a bolt.

Nun ist eine Tür frei zugänglich, so dass der Riegel -in dieser Anmeldung als Sperrbolzen bezeichnet- von Hand oder mittels eines in die Tür steckbaren Schlüssels aus seinem Eingriff gezogen werden kann. Diese Zugänglichkeit ist bei Maschinen nicht gegeben. Insbesondere ist bei vielen Maschinen die Handbetätigung nicht möglich, wenn es darum geht, ein gleitend bewegliches Teil mit einem anderen formschlüssig zu verbinden. Aufgabe der Erfindung ist es, eine Verriegelungseinrichtung nach dem Oberbegriff so auszugestalten, dass ein Gleitkörper auf bzw. an seinem Führungskörper formschlüssig festgelegt werden kann, ohne dass hierzu Anstalten getroffen werden müssen, welche von außen an Gleitkörper oder/und Führungskörper angebracht sind, welche die Bauausmaße vergrößern oder welche die Handhabung, Bedienung und Funktion von Gleitkörper und/oder Führungskörper zu behindern.A door is now freely accessible, so that the bolt - referred to as a locking pin in this application - can be pulled out of its engagement by hand or by means of a key that can be inserted into the door. Machines do not have this accessibility. In particular, manual operation is not possible with many machines when it comes to positively connecting one slidingly movable part with another. The object of the invention is to design a locking device according to the preamble in such a way that a sliding body can be fixed positively on or on its guide body without having to take steps which are attached to the sliding body and / or guide body from the outside which the Increase structural dimensions or which hinder the handling, operation and function of the sliding body and / or guide body.

Diese Aufgabe ergibt sich z.B. und insbesondere an einem Weichenantrieb für die Weiche eines Eisenbahngleises, der mit den Weichenzungen der Weiche zur Verschiebung in eine der Endlagen -bei der Weiche als Anlagepositionen bezeichnet- durch eine senkrecht zum Eisenbahngleis axial verschieblich gelagerte Stellstange verbunden ist, welche in jeder der Endlagen/ Anlagepositionen mittels einer ortsfesten Blockiereinrichtung formschlüssig festlegbar ist und zur Sicherheit auch festgelegt sein muß. Eine solche Weiche hat denThis task arises, for example, and in particular on a turnout drive for the turnout of a railroad track, which is connected to the turnout tongues of the turnout for shifting into one of the end positions - referred to as contact positions on the turnout - by an actuating rod that is axially displaceable perpendicular to the railway track and which is each of the end positions / contact positions by means of a stationary blocking device can be determined and must also be determined for security. Such a switch has the

Vorteil, dass sie nach den Sicherheitsvorschriften mit hoher Frequenz befahren werden darf, da durch den Formschluß sichergestellt ist, dass die anliegende Weichenzunge sich nicht durch Verbiegung oder Erschütterung der Geleise unbeabsichtigt abheben kann. Diese Weiche hat den Nachteil, dass sie nicht "stumpf", das bedeutet in Gegenrichtung aufgefahren werden kann. Entweder muß zum Befahren in Gegenrichtung die Weiche umgestellt werden oder es müssen Einrichtungen vorgesehen sein, um den Formschluß zwischen der anliegenden Zunge und dem Gleis aufzuheben, z.B. eine Verklammerung zu lösen. Diese Einrichtungen sind zusätzlich zu dem Weichenantrieb anzubringen und auch örtlich unterzubringen. Für Weichenantriebe, die zwischen den Schienen der Weiche angebracht und daher besonders kompakt sind -siehe z.B. DE102013009395A1 und DE102013009116A1 - und überdies statt Wartung oder Reparatur einfach ausgetauscht werden können, sind derartige äußere, d.h. nicht in den Antrieb integrierte Einrichtungen nicht nur störend sondern auch sicherheitstechnisch bedenklich. Auf die Beschreibung der DE102013009395A1 und DE102013009116A1 wird in und mit dieser Anmeldung ausdrücklich Bezug genommen, da die Erfindung namentlich diese Weichentriebe fortbildet und die Anbringung des Weichenantriebs zwischen den Schienen der Weiche ermöglicht.. Die Lösung ergibt sich für ein allgemein brauchbares Maschinenelement aus Anspruch 1, für dessen Anwendung an einem Weichenantrieb aus Anspruch 5.The advantage is that it can be driven on with high frequency according to the safety regulations, since the form fit ensures that the adjacent switch tongue cannot unintentionally lift off due to bending or shaking of the tracks. This switch has the disadvantage that it is not "blunt", which means that it can be opened in the opposite direction. Either the switch has to be adjusted for driving in the opposite direction or devices have to be provided to break the positive connection between the adjacent tongue and the track, for example to release a clamping. These devices are to be installed in addition to the point machine and also to be accommodated locally. For point machines that are installed between the rails of the points and are therefore particularly compact - see e.g. DE102013009395A1 and DE102013009116A1 and, moreover, can be simply exchanged instead of maintenance or repair, such external devices, ie devices not integrated into the drive, are not only disruptive but also questionable in terms of safety. On the description of the DE102013009395A1 and DE102013009116A1 is expressly referred to in and with this application, since the invention specifically develops these switch drives and enables the switch drive to be attached between the rails of the switch. The solution results for a generally useful machine element from claim 1, for its use on a switch drive Claim 5.

  • Das Einziehen/Eintreiben des Sperrbolzens aus seiner Sperrstellung in seine Neutralstellung. Hierzu dient eine Entsperr-Wirkpaarung (30,20) aus zwei relativ auf einander gleitend bewegbaren Kanten und/oder Flächen, welche in der durch Geradführung (8) des Sperrbolzens und Gleitbahn (3) des Gleitkörpers aufgespannten Ebene liegen und welche eine zur Geradführung des Sperrbolzens -vorzugsweise- unter 45° geneigte Wirkrichtung haben,
    Eine solche Eintreibfläche kann an dem Betätigungsende des Sperrbolzens oder an dem Führungskörper gebildet werden. (Anspruch 2) Durch Einziehen des Steckschlüssels taucht der Sperrbolzen in die Kontur des Gleitkörpers ein, indem er in eine Aussackung der Tasche gerät und nur noch in die Geradführung des Gleitkörpers hineinragt, nicht darüber hinausragt. Es besteht also in einer Richtung der Relativbewegung Gleitkörper/Steckschlüssel über die Schubkante und den Sperrbolzen Formschluß. Die Aussackung geht auf ihrer anderen Seite in die oben erwähnte Schubkante über
The pocket in the socket wrench has surfaces and edges in the cross-section in the direction of insertion, which interact with the socket wrench depending on the position and direction of movement of the socket wrench and exercise different functions on the locking pin, namely:
  • a pushing effect in the direction of movement of the relative movement between the socket wrench and the sliding body, eg the insertion direction. For this purpose an active pairing, called Thrust-active pairing of surfaces and / or edges, one of which is a thrust edge running transversely to the relative direction of movement, which engages the straight area of the locking pin with positive locking in the insertion direction and through this locking pin a the sliding body and the socket wrench in one of the relative directions of movement connects.das expulsion of the locking pin from the contour of the sliding body into its locking position for the positive connection of the sliding body with the guide body in at least one direction of movement of the relative movement between the guide body and the sliding body. For this purpose, an effective pairing, called a locking-effective pairing, consists of surfaces and / or edges on the actuating end of the locking bolt on the one hand and the pocket on the other. This active pairing has a drive-out surface which is inclined to the drive-out direction, preferably at 45 °. The expulsion surface lies on the locking pin and / or the pocket. In any case, the pairing of surfaces includes a drive-out edge which lies on the side of the pocket facing away from the pushing edge in the direction of insertion. The blocking of the retraction movement of the locking bolt in its blocking position. For this purpose, an active pairing, called a locking-active pairing, consists of surfaces and / or edges, one of which is a locking surface, which adjoins the drive edge and is oriented transversely to the straight line of the locking pin and engages under the end of the locking pin in its locking position.
  • Retraction / driving of the locking pin from its locking position into its neutral position. For this purpose, an unlocking-active pairing (30, 20) consisting of two edges and / or surfaces that can slide relative to one another and which lie in the plane spanned by the straight guide (8) of the locking bolt and slide (3) of the sliding body and which are a straight line of the Locking bolt -preferably- have an effective direction inclined at 45 °,
    Such a drive-in surface can be formed on the actuating end of the locking pin or on the guide body. (Claim 2) By pulling in the socket wrench, the locking bolt dips into the contour of the sliding body by getting into a recess in the pocket and only protruding into the straight guide of the sliding body, not protruding beyond it. So there is a positive fit in one direction of the relative movement of the sliding body / socket wrench over the sliding edge and the locking bolt. The bulge merges on its other side into the abovementioned sliding edge

Bei entsprechender Relativbewegung des Steckschlüssels zu dem Gleitkörper nimmt die Schubkante den Sperrbolzen und dieser nimmt den Gleitkörper mit, so dass bei der Bewegung des Gleitkörpers dieser an der Einziehfläche in Richtung seiner Geradführung abgleitet und in der Aussackung der Tasche verschwindet. Damit ist der Formschluß aufgehoben und der Gleitkörper kann an dem Führungskörper in Gleitrichtung durch mehr oder weniger frei bewegt werden. Um zu verhindern, dass der Sperrbolzen eine undefinierte Stellung einnimmt, wird nach Anspruch 3 der Eingriff (12) des Führungskörpers (4) doppelseitig ausgebildet ist als kegeliges Loch bzw. Nut mit spitz zulaufenden Flanken 30, so dass der Sperrbolzen bei jeder Relativbewegung von Führungskörpers (4) und Gleitkörper (2) in seine Neutralstellung (10) eingetrieben wird.With a corresponding relative movement of the socket wrench to the sliding body, the pushing edge takes the locking pin and this takes the sliding body with it, so that when the sliding body moves, it is on the retraction surface in the direction of its straight line slides off and disappears into the pouch. Thus, the form fit is canceled and the sliding body can be moved more or less freely on the guide body in the sliding direction. In order to prevent the locking bolt from assuming an undefined position, the engagement (12) of the guide body (4) is designed on both sides as a conical hole or groove with tapered flanks 30, so that the locking bolt moves with every relative movement of the guide body (4) and sliding body (2) is driven into its neutral position (10).

In der Weiterbildung nach Anspruch 4 löst die Erfindung auch das Problem, einen beweglichen Körper in einer Endlage zwischen zwei Anschlägen fomschlüssig festzulegen, bei einer insbesondere plötzlichen Einwirkung einer äußeren Kraft jedoch die freie Bewegung des Körpers aus der Endlage ohne Aufhebung des Formschlusses zuzulassen. Diese Situation tritt insbesondere in Weichenantrieben auf, wenn eine formschlüssig Anliegende und festgelegte Weiche ohne Betätigung des Weichenantriebs von hinten befahren, d.h. aufgefahren wird. Zur Lösung erfolgt die Bewegung des Gleitkörpers in die Endlage durch Antrieb des Führungskörpers bei kraftschlüssiger Verbindung mit dem Gleitkörper und Betätigung des Steckschlüssels derart, dass der Sperrbolzen in seine Sperrstellung ausgetrieben wird. Da nunmehr der Führungskörper formschlüssig festgelegt wird, entsteht ein formschlüssiger Kraftfluß von dem Gleitkörper zu dem Führungskörper. Durch Bewegung des Steckschlüssels in der anderen Richtung mittels äußerer Kraft und dementstrechen eintreiben des Sperrbolzens in seine Neutralstellung wird der Formschluß aufgehoben und der Gleitkörper ist durch den Steckschlüssel aus der Endlage herausziehbar.In the development according to claim 4, the invention also solves the problem of positively securing a movable body in an end position between two stops, but allowing the body to move freely out of the end position without breaking the interlock in the event of a particularly sudden external force. This situation occurs especially in point machines when a form-fitting and fixed point is driven over from behind without actuating the point machine, i.e. is driven on. To solve this, the sliding body is moved into the end position by driving the guide body with a force-fit connection with the sliding body and actuating the socket wrench in such a way that the locking pin is driven out into its locking position. Since the guide body is now fixed in a form-fitting manner, there is a form-fitting flow of force from the sliding body to the guide body. By moving the socket wrench in the other direction by means of external force and then driving the locking pin into its neutral position, the positive locking is canceled and the sliding body can be pulled out of the end position by the socket wrench.

Diese Erfindung wird nach Anspruch 5 auf einen Weichenantrieb angewandt.This invention is applied according to claim 5 to a point machine.

Dabei gilt es, zwei relativ zu einander an einer Führungsbahn gleitend bewegliche Gleitkörper mit einander derart zu verbinden, dass jeweils einer formschlüssig mit dem gemeinsamen Führungskörper verbindbar ist, dass der jeweils andere lediglich mit Kraftschluß festgelegt ist und nach dessen Überwindung beweglich bleibt und dass durch seine Bewegung der Formschluß des anderen gelöst und beide Gleitkörper synchron bewegbar sind.It is important to connect two sliding bodies, which can slide relative to one another on a guide track, with one another in such a way that in each case one can be positively connected to the common guide body, that the other is only fixed with frictional connection and remains movable after overcoming it and that by its Movement of the form fit of the other released and both sliding bodies can be moved synchronously.

In dieser Lösung werden der Sperrschlüssel und die Verriegelungseinrichtung nach einem der vorhergehenden Ansprüche durch Spiegeln verdoppelt, so dass die Steckschlüssel an den Enden spiegelbildlich ausgebildet sind und dieselben Funktionen aber gegenläufig jeweils in dem einen und dem anderen Gleitkörper ausüben.In this solution, the locking key and the locking device according to one of the preceding claims are doubled by mirroring, so that the socket wrenches are mirror-inverted at the ends and exercise the same functions in opposite directions in one and the other sliding body.

Bei dem oben genannten Weichenantrieb ergibt sich dabei das weitere Problem, nicht nur die zuvor beschriebene Beweglichkeit bzw. den Formschluß für jede der beiden Weichenzungen zu gewährleisten sondern auch den Antrieb für die normale Synchronbewegung beider Weichenzungen bei der regulären Weichenverstellung einzubringen. Hierzu sind der Steckschlüssel 13L und 13R durch einen Mittelkörper verbunden und in beiden Steckrichtungen und Gleitrichtungen beweglich und antreibbar. Dazu wird der Mittelkörper kraftschlüssig mit dem Führungskörper 4 verbunden. Dieser wird beweglich parallel zur Bewegungsrichtung der Gleitkörper geführt und mit einem Linearantrieb, z.B. einer in Gleitrichtung ausgerichteten Zahnstange 24 ausgestattet. Die Zahnstange ist getrieblich mit einem Antriebsmotor verbunden. Der Führungskörper 4 ist also zwischen den Endlagen der Weichenzungen beweglich und in jeder der Endlagen durch jeweils eine Sperrzunge 26 einer Blockiereinrichtung derart formschlüssig festgelegt, dass die am Gleis formschlüssig anliegende Weichenzunge in der Gegenrichtung über den mit ihr verbundenen Gleitkörper und den in ihm geradgeführten Sperrbolzen formschlüssig mit dem Führungskörper gehalten wird. Dabei wird der Formschluß zwischen Sperrbolzen und Führungskörper dadurch hergestellt, dass der Steckschlüssel in das Einsteckende des Gleitkörpers weit eintaucht, dadurch der Sperrbolzen ausgetrieben und durch die Sperrfläche 19 dort in der Sperrstellung 11 gehalten wird. Dabei sind die unter 45° ausgerichteten Wirkkanten/Wirkflächen in den Taschen und an den Sperrbolzen so geneigt, dass durch größere Eintauchtiefe des Steckschlüssels der Sperrbolzenin seine Sperrstellung ausgetrieben und bei geringerer Eintauchtiefe in seine Neutralstellung eingezogen wird.In the case of the switch drive mentioned above, the further problem arises of not only ensuring the previously described mobility and positive locking for each of the two switch blades but also the drive for the normal synchronous movement of both switch blades during the regular switch adjustment bring in. For this purpose, the socket wrenches 13L and 13R are connected by a central body and can be moved and driven in both insertion directions and sliding directions. For this purpose, the central body is connected to the guide body 4 in a force-locking manner. This is movably guided parallel to the direction of movement of the sliding body and equipped with a linear drive, for example a rack 24 aligned in the sliding direction. The rack is geared to a drive motor. The guide body 4 is therefore movable between the end positions of the switch tongues and in each of the end positions is positively fixed by a locking tongue 26 of a blocking device in such a way that the switch tongue, which is in a form-fitting manner on the track, is positively locked in the opposite direction via the sliding body connected to it and the blocking bolt guided in it is held with the guide body. The form fit between the locking pin and the guide body is established in that the socket wrench dips far into the insertion end of the sliding body, thereby driving out the locking pin and holding it in the locking position 11 there by the locking surface 19. The active edges / active surfaces in the pockets and on the locking pins, which are aligned at 45 °, are inclined so that the locking pin is driven out into its locking position when the socket wrench is immersed to a greater depth and is drawn into its neutral position at a lower immersion depth.

Der andere mit der nicht-anliegenden Weichenzunge verbundene Gleitkörper bleibt für einen Totweg frei beweglich, welcher durch den Freiraum des an diesem Gleitkörper geradgeführten Sperrbolzen in seiner Tasche des Steckschlüssels definiert ist. Die nicht-anliegende Weichenzunge kann sich also über diesen Totweg bewegen, wenn die Weiche stumpf aufgefahren wird. Bei dieser Bewegung hintergreift der in ihrem Gleitkörper geradgeführte Sperrbolzen nach dem Totweg die Schubkante 16 in der Tasche des Steckschlüssels, zieht diesen aus dem Einsteckende des anderen formschlüssig festliegenden Gleitkörper hinaus, zieht dadurch die Sperrfläche 19 unter dem Sperbolzen weg, zieht den Sperrbolzen durch Abgleiten an der Eintreibfläche 20 in die Kontur des Gleitkörpers zurück und löst dadurch den Formschluß der nicht-anliegende Weichenzunge . Auch diese kann nunmehr stumpf bis in die andere Endlage der Weiche aufgefahren werden, wobei sich der Kraftschluss zwischen Führungskörper und Mittelkörper mit Steckschlüsseln löst. Durch seinen Antrieb wird nunmehr der Führungskörper ebenfalls in seine andere Endlage gefahren, dort der Kraftschluß zu dem Steckschlüssel wieder hergestellt, dabei der Steckschlüssel in den Gleitkörper der nicht-anliegende Weichenzunge gesteckt und der Formschluß nunmehr an der jetzt anliegenden Weichenzunge hergestellt, wie zuvor beschrieben.The other sliding body connected to the non-abutting switch tongue remains freely movable for a dead path, which is defined by the free space of the locking bolt, which is guided straight on this sliding body, in its pocket of the socket wrench. The switch tongue that is not in contact can therefore move over this dead path when the switch is opened bluntly. During this movement, the locking bolt, which is straight in its sliding body, engages behind the pushing edge 16 in the socket wrench's pocket after the dead travel, pulls it out of the insertion end of the other positively fixed sliding body, thereby pulling the locking surface 19 under the locking bolt, and pulls the locking bolt by sliding off the driving surface 20 back into the contour of the sliding body and thereby releases the positive locking of the non-abutting switch tongue. This can now also be moved up to the other end position of the switch, the frictional connection between the guide body and the central body being released with socket wrenches. By its drive, the guide body is now also moved to its other end position, where the frictional connection to the socket wrench is restored, the socket wrench is inserted into the sliding body of the non-abutting switch tongue and the form-fit is now established on the now abutting switch tongue, as described above.

Figur 1 und 2 zeigen eine Verriegelungseinrichtung 1 für einen Gleitkörper 2 in Gestalt einer Stellstange. Der Gleitkörper ist geradgeführt in dem Führungskörper 4, einem Maschinenteil mit einer Führungsbuchse. Der Gleitkörper 2 ist beweglich von Endlage 6 nach -in Fig.1 und 2- links. In der Endlage 6 ist der Gleitkörper formschlüssig festgelegt. Hierzu dient

  • in Fig.1C die Verriegelungseinrichtung im Zusammenwirken des Sperrbolzens 7 mit einem Fixierloch (Eingriff 12) in der Gleitbahn 3 des Führungskörper 4,
  • in Fig.2C die Verriegelungseinrichtung im Zusammenwirken des Anschlags 27 -hier eine unter 45° geneigte Anschlagfläche des Sperrbolzens 7 - mit der Rückseite des Führungskörpers 4 -hier Sperrfläche 19, unter 45° gleichsinnig wie Anschlagfläche 27 geneigt.
Figure 1 and 2 show a locking device 1 for a sliding body 2 in the form of an adjusting rod. The sliding body is guided in a straight line in the guide body 4, a machine part with a guide bushing. The sliding body 2 is movable from the end position 6 to -in Fig.1 and 2 - Left. In the end position 6, the sliding body is positively fixed. Serves for this
  • in Fig.1C the locking device in the interaction of the locking bolt 7 with a fixing hole (engagement 12) in the slide 3 of the guide body 4,
  • in Fig. 2C the locking device in the interaction of the stop 27 - here a 45 ° inclined stop surface of the locking pin 7 - with the back of the guide body 4 - here the locking surface 19, inclined at 45 ° in the same direction as the stop surface 27.

Zur Betätigung des Sperrbolzens 7 in Richtung der Geradführung weist die Verriegelungseinrichtung einen Steckschlüssel 13 auf, der von der Bedienungsseite des Gleitkörper her in Bewegungsrichtung des Gleitkörpers in Steckrichtung in den Steckschlüssel tiefer hinein gesteckt -große Eintauchtiefe- und anders herum weiter herausgezogen -geringere Eintauchtiefe- werden kann.To actuate the locking pin 7 in the direction of the straight guide, the locking device has a socket wrench 13 which is inserted deeper into the socket wrench from the operating side of the sliding body in the direction of movement of the sliding body in the plugging direction - large immersion depth - and the other way round pulled out further - smaller immersion depth can.

Dabei ist die Relativlage des Steckschlüssels 13 in dem Gleitkörper so, dass (siehe Fig.1B und 2B) der Sperrbolzen 7 in seine Sperrstellung 11 ausgetrieben ist durch Zusammenwirken der Austreibkante 17 am Steckschlüssel 13 und der zur Gleitrichtung und Geradführung des Sperrbolzens unter ca 45° geneigten Austreibfläche 18 an der Vorderseite des Sperrbolzens 7, jeweils in Bewegungsrichtung des Gleitkörpers 2 gesehen.The relative position of the socket wrench 13 in the sliding body is such that (see Fig.1B and 2 B ) the locking pin 7 is driven out into its locking position 11 by the interaction of the expulsion edge 17 on the socket wrench 13 and the expulsion surface 18 inclined at about 45 ° to the sliding direction and straight guidance of the locking pin on the front of the locking pin 7, each seen in the direction of movement of the sliding body 2.

Der Sperrbolzen 7 ist in dem Gleitkörper in vorzugsweise senkrechter Richtung zur Bewegungsrichtung des Gleitkörpers geradgeführt und frei beweglich zwischen zwei Endstellungen, und zwar

  • Der Sperrstellung 11, in der er aus der Kontur des Gleitkörpers 2 in die Gleitbahn 3 des Führungskörpers 4 ragt und
  • Der Neutralstellung 10, in der er in die Kontur des Gleitkörpers 2 zurückgezogen wird und die Relativbewegung zwischen Führungskörper 4 und Gleitkörper 2 freigibt.
The locking pin 7 is in the sliding body in a straight line, preferably perpendicular to the direction of movement of the sliding body and freely movable between two end positions, namely
  • The locking position 11, in which it protrudes from the contour of the sliding body 2 into the sliding track 3 of the guide body 4 and
  • The neutral position 10, in which it is pulled back into the contour of the sliding body 2 and releases the relative movement between the guide body 4 and the sliding body 2.

Der Sperrbolzen in Fig.1 ist eine sich senkrecht zur Zeichenebene erstreckende, jedoch kurze Platte von ausreichender Dicke; sie muß die Biege- und Scherkräfte ertragen können, die in der Gleitbahn bei der Relativbewegung von Führungs- und Gleitkörper auftreten. Sie ist etwa auf der Hälfte ihrer Höhe um etwa 45° abgeknickt.The locking pin in Fig.1 is a short plate of sufficient thickness extending perpendicular to the plane of the drawing; it must be able to withstand the bending and shear forces, which occur in the slideway during the relative movement of the guide and sliding bodies. It is bent by about 45 ° at about half its height.

Sie bildet mit dem abgeknickten Bereich auf der der Schubkante 16 zugewandten Seite die Eintreibfläche 20, welche mit der Eintreibkante 30 am inneren Ende der Schubfläche zusammenwirkt (Fig.1D) und die Eintreib-Wirkpaarung bildet.Together with the bent area on the side facing the pushing edge 16, it forms the driving surface 20, which interacts with the driving edge 30 at the inner end of the pushing surface ( Fig.1D ) and forms the driving-action pairing.

Die Rückseite des abgeknickten Bereichs, welche der Austreibkante 17 zugewandt ist, bildet die Austreibfläche 18, welche mit der mit der Austreibkante 18 zusammenwirkt und die Austreib-Wirkpaarung bildet.The rear side of the bent area, which faces the expulsion edge 17, forms the expulsion surface 18, which interacts with the expulsion edge 18 and forms the expulsion-effective pairing.

Der Sperrbolzen in Fig.2 ist runder zylindrischer Bolzen von ausreichender Dicke; er muß die Biege- und Scherkräfte ertragen können, die in der Gleitbahn bei der Relativbewegung von Führungs- und Gleitkörper auftreten. An beiden Endflächen, jedoch begrenzt durch dieselben Zylindermantellinien, besitzt der Sperrbolzen jeweils eine die jeweilige Endfläche anschneidende sich senkrecht zur Zeichenebene erstreckende Anfasung von etwa 45°. Die Anfasung an dem einen Sperrende 22 bildet die Eintreibfläche 20, welche mit dem Eingriff 12 an dem Führungskörper als Eintreibkante 30 zusammenwirkt und die Eintreib-Wirrkpaarung bildet. (Fig.2D)The locking pin in Fig. 2 is round cylindrical bolt of sufficient thickness; it must be able to withstand the bending and shear forces that occur in the sliding path during the relative movement of the guide and sliding body. At both end faces, but limited by the same cylinder surface lines, the locking bolt has a chamfer of approximately 45 ° which intersects the respective end face and extends perpendicular to the plane of the drawing. The chamfer at the one locking end 22 forms the drive-in surface 20, which interacts with the engagement 12 on the guide body as a drive-in edge 30 and forms the drive-in active pairing. ( Fig. 2D )

Die Anfasung an dem anderen Betätigungsende 21des Sperrbolzens dient als Austreibfläche 18, welche mit der Austreibkante 17 der Tasche zusammenwirkt und die Austreib-Wirkpaarung bildet (Fig.2B).The bevel on the other actuating end 21 of the locking pin serves as a drive-out surface 18, which interacts with the drive-out edge 17 of the pocket and forms the drive-out / active pairing ( Fig.2B ).

Es sei hervorgehoben, dass die geschilderten Eintreib- und Austreibpaarungen jeweils aus einer Fläche und zumindest einer damit zusammenwirkenden Kante bestehen. Beide sind regelmäßig austauschbar -Kante statt Fläche und umgekehrt. Eine Paarung kann jedoch auch aus zwei gleich gerichteten Flächen bestehen.It should be emphasized that the described drive-in and drive-out pairs each consist of a surface and at least one edge that interacts with it. Both are regularly interchangeable - edge instead of surface and vice versa. A pairing can, however, also consist of two surfaces facing the same direction.

Um die Wirkfunktion Eintreiben/Austreiben des Sperrbolzens relativ zu der Relativbewegung Steckschlüssel/Gleitkörper festzulegen, erfolgt eine horizontale Spiegelung der Verriegelungseinrichtung.In order to establish the operative function of driving in / driving out the locking pin relative to the relative movement of the socket wrench / sliding body, the locking device is mirrored horizontally.

Zur Ausübung seiner Verriegelungsfunktionen besitzt der Steckschlüssel 13 eine Tasche 15, in welche das Betätigungsende 14 des Sperrbolzens hineinragt. Die Kontur dieser Tasche in der Axialebene der Gleitrichtung 5 ist in Fig. 1 und 2 vergrößert dargestellt und die Funktionen der Kanten bzw. Flächen der Tasche im folgenden anhand der Fig.1,2 beschrieben.To exercise its locking functions, the socket wrench 13 has a pocket 15 into which the actuating end 14 of the locking pin protrudes. The contour of this pocket in the axial plane of the sliding direction 5 is in Fig. 1 and 2 shown enlarged and the functions of the edges or surfaces of the pocket below with reference to the Fig.1 , 2 described.

In den Fig.1A,2A ist der Sperrbolzen 7 eingezogen, so dass er nicht mit dem Führungskörper zusammenwirkt. Durch Bewegen des Steckschlüssels in Gleitrichtung 5 hintergreift die Schubkante 16 der Tasche den geraden, geradgeführten Bereich des Sperrbolzens und dieser hintergreift seine Geradführung 8 in dem Gleitkörper 2. Steckschlüssel, Sperrbolzen und Gleitkörper sind formschlüssig gegen die relative Gleitrichtung 5 verbunden und sind daher in Gleitrichtung 5 synchron bewegbar.In the Fig.1A , 2A the locking pin 7 is retracted so that it does not interact with the guide body. By moving the socket wrench in the sliding direction 5, the sliding edge 16 of the pocket engages behind the straight, straight-line area of the locking pin and this engages behind its straight guide 8 in the sliding body 2.Socket wrench, locking bolt and sliding body are positively connected against the relative sliding direction 5 and are therefore in the sliding direction 5 synchronously movable.

In den Fig.1B,2B wird der Sperrbolzen in Sperrrichtung aus der Tasche ausgetrieben. Dazu wird der Steckschlüssel in Schließrichtung 29 bewegt, so dass die der Schubkante 16 gegenüberliegende Austreibkante 17 mit der unter 45° geneigten Austreibfläche 18 am Sperrende 22 des Sperrbolzen 7 im Austreibsinne zusammenwirkt bis -wieIn the Fig.1B , 2 B the locking pin is driven out of the pocket in the locking direction. For this purpose, the socket wrench is moved in the closing direction 29 so that the drive edge 17 opposite the push edge 16 interacts with the drive surface 18 inclined at 45 ° at the locking end 22 of the locking bolt 7 in the drive direction

In den Fig.1C,2C gezeigt- der Sperrbolzen 7 vollständig aus der Kontur des Gleitkörper herausgefahren ist, in den Eingriff 12 (Fig.1C) am Führungskörper 4 formschlüssig eingreift bzw. an der Anschlagfläche 12 (Fig.2C) am Führungskörper 4 formschlüssig angreift, dabei durch die Sperrfläche19 am Eintreiben in die Tasche gehindert wird und so die Relativbewegung zwischen Gleitkörper und Führungskörper gegen die angezeigte Relativbewegung 5 formschlüssig sperrt.In the Fig.1C , 2C shown - the locking pin 7 has moved completely out of the contour of the sliding body, into engagement 12 ( Fig.1C ) engages positively on the guide body 4 or on the stop surface 12 ( Fig. 2C ) engages the guide body 4 in a form-fitting manner, thereby being prevented by the blocking surface 19 from being driven into the pocket and thus locks the relative movement between the sliding body and the guide body in a form-fitting manner against the indicated relative movement 5.

In den Fig.1D,2D wird gezeigt, dass allein der Steckschlüssel 13 in Entsperr-Richtung 31 - also gegen die Schließrichtung 29 bewegt wird.In the Fig.1D , 2D it is shown that only the socket wrench 13 is moved in the unlocking direction 31 - that is, against the closing direction 29.

In Fig.1D gerät dadurch die an die Schubfläche 16 anschließende Eintreibkante 30 in Wirkverbindung mit der -vorzugsweise- unter 45° zur Geradführung 8 des Sperrbolzens liegenden Eintreibfläche 20.In Fig.1D As a result, the drive-in edge 30 adjoining the thrust surface 16 comes into operative connection with the drive-in surface 20, which is preferably at 45 ° to the straight-line guide 8 of the locking bolt.

In Fig.2D gerät dadurch die Anschlagfläche 12 an dem Führungskörper als Eintreibkante 30 in Wirkverbindung mit der -vorzugsweise- unter 45° zur Geradführung 8 des Sperrbolzens liegenden Eintreibfläche 20 am Sperrende 22 des Sperrbolzens 7.In Fig. 2D As a result, the stop surface 12 on the guide body as a drive-in edge 30 comes into operative connection with the drive-in surface 20 on the locking end 22 of the locking pin 7, which is preferably at 45 ° to the straight-line guide 8 of the locking pin.

Der Sperrbolzen wird wieder eingezogen bis er die in Fig.1A,2A gezeigte Position (s.o.) erreicht hat.The locking pin is retracted until it reaches the in Fig.1A , 2A position shown (see above).

Die Fig.3A-3D und 4A-4D zeigen Gleitkörper, Führungskörper und Verriegelungseinrichtung in denselben Positionen wie vor. In Fig. 3 ist der Eingriff 12 im Führungskörper 4 ein Kegeliges Loch oder eine Nut mit Flanken 30, die kegelig spitz auf einander zulaufen im Querschnitt, der in der Bewegungsebene liegt. Wenn der Sperrbolzen durch Sperrfläche 19 untergriffen wird (Fig.3A), hindert er die Relativbewegung zwischen Gleitkörper und Führungskörper in beiden Richtungen formschlüssig, wenn nicht, wirken die beiden Flanken als Eintreibkanten, die ihn in seine Neutralstellung drücken (Fig.3B).The Figures 3A-3D and 4A-4D show sliding body, guide body and locking device in the same positions as before. In Fig. 3 the engagement 12 in the guide body 4 is a conical hole or a groove with flanks 30 which conically taper towards each other in a cross section that lies in the plane of movement. If the locking pin is engaged by locking surface 19 ( Fig.3A ), it prevents the relative movement between the sliding body and the guide body in both directions with a positive fit, if not, the two flanks act as driving edges that push it into its neutral position ( Fig.3B ).

In Fig 4 ist gezeigt, daß die Relativbewegung zwischen Führungskörper 4 und Gleitkörper 2 in einer Endlage (Fig.4A) einerseits durch einen am Gleitkörper befestigten Anschlag 27 und andererseits durch den an seiner anderen Seite anliegenden Sperrbolzen 7 -hier in der Ausführung nach Fig.2- relativ zu dem Gleitkörper in beiden Richtungen formschlüssig festgelegt wird bei geringer Eintauchtiefe des Steckschlüssels in dem Gleitkörper. Durch Vergrößerung der Eintauchtiefe durch eine auf den Steckschlüssel wirkende Kraft 31 kann der Sperrbolzen in die Neutralstellung eingezogen werden (Fig.4B-C) und der Gleitkörper durch de auf den Steckschlüssel wirkende Kraft 31 in Entsperr-Richtung 31 in dieser Richtung relativ zu dem Führungskörper bewegt werden.,In Fig 4 it is shown that the relative movement between guide body 4 and sliding body 2 in an end position ( Fig.4A ) on the one hand by a stop 27 attached to the sliding body and on the other hand by the locking pin 7 resting on its other side - here in the execution Fig. 2 - Is fixed positively in both directions relative to the sliding body with a small immersion depth of the socket wrench in the sliding body. By increasing the immersion depth by applying a force 31 to the socket wrench, the locking pin can be pulled into the neutral position ( Fig. 4B-C ) and the sliding body can be moved in this direction relative to the guide body by de force 31 acting on the socket wrench in the unlocking direction 31.

Figur 6 zeigt in Aufsicht eine Weiche. Die Weichenzungen 102 können durch den Weichenantrieb 103 abwechselnd zur Anlage an die linke Schiene oder rechte Schiene 101 - so in Figur 6 - gebracht werden.To build the switch, the DE102013009395A1 and DE102013009116A1 the representation of the principle of a switch, the associated switch drive as Fig. 6 and the following description adopted:
Figure 6 shows a switch in plan view. The switch tongues 102 can alternately rest against the left rail or right rail 101 by the switch drive 103 - see FIG Figure 6 - to be brought.

Der Weichenantrieb liegt bei dieser Ausführung, die sich insbesondere für beengte Verhältnisse eignet, zwischen den beiden Weichenzungen. Die Stellstange 108 des Weilchenantriebs 103 ist mit beiden Weichenzungen verbunden. Der Weichenantrieb 103 ist in einem Antriebsgehäuse 104 untergebracht. Gezeigt ist der geschlossene Zustand. Daher sind die Einzelteile des Weichenantriebes, nämlich Antriebsmotor 105, Getriebezug 107.1, Stellkraftbegrenzungskupplung 106 und Getriebezug 107.2 sowie die Blockier- Einrichtung 109 nur angedeutet. Diese Teile werden in den DE102013009395A1 und DE102013009116A1 beschrieben und es wird hierauf in Gänze Bezug genommen. Dieser gezeigte Weichenantrieb kann nach der Erfindung umgebaut werden durch Austausch der Stellstangen, im folgenden als Gleitkörper bezeichnet und beschrieben, das Einfügen der erfindungsgemäßen Verriegelungseinrichtung 1, bestehend aus doppelseitigem Steckschlüssel 13 und Sperrbolzen 7 -wie anhand der Figur 5 nunmehr beschrieben.In this version, which is particularly suitable for confined spaces, the point drive is located between the two switch blades. The control rod 108 of the little drive 103 is connected to both switch blades. The point drive 103 is accommodated in a drive housing 104. The closed state is shown. Therefore, the individual parts of the switch drive, namely drive motor 105, gear train 107.1, actuating force limiting clutch 106 and gear train 107.2 as well as the blocking device 109 are only indicated. These parts are in the DE102013009395A1 and DE102013009116A1 and incorporated herein by reference in its entirety. This point drive shown can be rebuilt according to the invention by exchanging the control rods, referred to and described below as sliding bodies, inserting the locking device 1 according to the invention, consisting of double-sided socket wrench 13 and locking bolt 7 -as based on the Figure 5 now described.

Die nachfolgende Bezugszeichenaufstellung benennt als Synonyme die funktionsgleichen Elemente und Teile aus den in Bezug genommenen DE102013009395A1 und DE102013009116A1 (siehe oben).The following list of reference symbols names as synonyms the functionally identical elements and parts from those referred to DE102013009395A1 and DE102013009116A1 (see above).

Es erfolgt hierzu eine Spiegelbildliche Verdoppelung der zuvor beschriebenen Verriegelungseinrichtungen und Steckschlüssel, wobei die Spiegelebene die mittlere Radialebene der Stellstange des bekannten Weichenantriebs ist. Dabei ist die Stellstange in zwei Gleitkörper 2L und 2R geteilt, die sich mit ihren Einsteckenden 23L und Einsteckende 23R mit Abstand gegenüber liegen. Die Einsteckenden werden durch die Steckschlüssel 13L bzw. 13R an den beiden Endflächen des Mittelkörpers 113 verbunden, der ebenfalls an der besagten Spiegelebene -also mittig zwischen den Ösen 108.1 und 108.2 gespiegelt ist. Dadurch sind die Weichenzungen und die damit fest verbundenen Gleitkörper (2L,2R) mit einander derart verbunden sind, dass sie durch den Weichenantrieb bei -bis auf einen kleinen Totweg -nachfolgend beschrieben- konstant bleibendem Abstand synchron zwischen den Anlagepositionen verschiebbar sind und durch die beim Auffahren der Weiche auf die Weichenzungen ausgeübte Kraft in den Grenzen der durch die Verriegelungen vorgegebenen Relativbeweglichkeit von Steckschlüssel und Gleitkörper auch unabhängig von einander bewegbar sind.For this purpose, the locking devices and socket wrenches described above are duplicated in a mirror image, the mirror plane being the central radial plane of the control rod of the known switch drive. The control rod is divided into two sliding bodies 2L and 2R, which are at a distance from one another with their insertion ends 23L and insertion end 23R. The insertion ends are connected by the socket wrench 13L or 13R on the two end faces of the central body 113, which is also mirrored on the said mirror plane - that is, centered between the eyes 108.1 and 108.2. As a result, the switch tongues and the sliding bodies (2L, 2R) firmly connected to each other are connected to each other in such a way that they can be moved synchronously between the contact positions by the switch drive at a constant distance - except for a small dead path - described below - and by the When the switch moves onto the switch tongues, the force exerted on the switch tongues can also be moved independently of one another within the limits of the relative mobility of socket wrench and sliding body predetermined by the locks.

In den Gleitkörpern 2L und 2R sind Sperrbolzen 7L und 7R geradgeführt, die wie oben zu Fig.1,2 beschrieben, jedoch an der Spiegelebene gespiegelt ausgeführt und eingesetzt sind.In the sliding bodies 2L and 2R locking pins 7L and 7R are straight out, which as above Fig.1 , 2 described, but executed and used mirrored at the mirror plane.

Die Sperrbolzen 7L und 7R ragen mit ihren Betätigungsenden in die Taschen 15L bzw.15R an dem jeweiligen linken und rechten Ende der Steckschlüssel. Die Taschen 15L bzw.15R sind -wie beschrieben ausgeführt, jedoch an der Spiegelebene gespiegelt. Dabei sind die Taschen so angeordnet, dass die Schubkanten 16L bzw. 16R zur gemeinsamen Spiegelebene weisen. Der bekannte Blockierblock fungiert hier als Führungskörper 4. Er ist über eine kraftschlüssige Einrastpaarung (StdT.: 13) -hier schematisch dargestellt und mit 113 für Einrastrolle, Einrastkerbe, Führungsbahn und Andruckfeder bezeichnet- anstelle mit der Stellstange mit dem zwischen den Einsteckenden der Gleitkörper in der Spiegelebene liegenden Bereich des Steckschlüssels 13 kraftschlüssig verbunden.The locking pins 7L and 7R protrude with their actuating ends into the pockets 15L and 15R at the respective left and right ends of the socket wrench. The pockets 15L and 15R are designed as described, but mirrored on the mirror plane. The pockets are arranged so that the sliding edges 16L and 16R point to the common mirror plane. The well-known blocking block functions here as guide body 4. It is shown here schematically via a force-fit snap-in pairing (StdT .: 13) and designated with 113 for snap-in roller, snap-in notch, guide track and pressure spring - instead of the control rod with the sliding body between the insertion ends of the slide body in the area of the socket wrench 13 lying on the mirror plane.

Der Führungskörper4 ist auch selbst in Gleitrichtung 5 beweglich zwischen zwei Endstellungen, welche durch Blockierzungen 109L und 109R formschlüssig festgelegt sind. Die Blockierzungen 109 werden -wie im StdT beschrieben vor die Stirnseiten des Führungskörpers 4 gefahren, um die Endlage der anliegenden Weichenzunge formschlüssig ortsfest festzulegen. Als Antrieb des Führungskörper 4 ist eine Zahnstange und ein Getriebe angedeutet.The guide body 4 is itself movable in the sliding direction 5 between two end positions which are positively fixed by locking tongues 109L and 109R. The blocking tongues 109 are moved in front of the end faces of the guide body 4, as described in the StdT, in order to fix the end position of the adjacent switch tongue in a form-fitting manner. A toothed rack and a gear mechanism are indicated as the drive for the guide body 4.

In Fig. 5A ist dargestellt, dass der Führungskörper 4 nach links bewegt wurde, um die linke Weichenzunge formschlüssig festzulegen. Dazu wird der Führungskörper 4 durch die eingefahrene Blockierzunge 109R rechts hintergriffen; der Sperrbolzen 7L ist ausgefahren und wird durch die Sperrfläche 19 am Einziehen gehindert. Er liegt an dem Eingriff 12L links am Führungskörper 4 an. Es versteht sich, dass die Beweglichkeit der anliegenden Weichenzunge selbst und damit auch der Gleitkörper durch die anliegende Schiene, an welcher die eine Weichenzunge anliegt, formschlüssig begrenzt ist.In Figure 5A it is shown that the guide body 4 has been moved to the left in order to fix the left switch tongue in a form-fitting manner. For this purpose, the guide body 4 is engaged from behind on the right by the retracted blocking tongue 109R; the locking pin 7L is extended and is prevented from being drawn in by the locking surface 19. It rests against the engagement 12L on the left on the guide body 4. It goes without saying that the mobility of the adjacent switch tongue itself, and thus also the sliding body, is positively limited by the adjacent rail on which the one switch tongue rests.

Fig.5 C und D zeigen den Vorgang, dass die Weiche nach recht umgelegt wird. Dazu wird der Führungskörper 4 durch den Antrieb unter Beibehaltung der kraftschlüssigen Verbindung mit dem Steckschlüssel 13 durch Einrastpaarung 113 B mittels Zahnstange nach rechts verfahren, nachdem zuvor die Blockierzunge 109R gelöst wurde. Der Zwischenzustand ist in Fig. 5C, die Endlage rechts in Fig.5D gezeigt. Nunmehr wird die Blockierzunge 109L vor die Stirnseite des Führungskörper 4 gefahren und Sperrbolzen 7R stützt sich auf der rechten Seite des Führungskörper 4 an dessen Eingriff 12R ab. Fig. 5 C and D show the process that the switch is turned to the right. For this purpose, the guide body 4 is moved to the right by the drive while maintaining the non-positive connection with the socket wrench 13 by latching pairing 113 B by means of a toothed rack after the blocking tongue 109R has been released beforehand. The intermediate state is in Figure 5C , the right end position in Fig.5D shown. The blocking tongue 109L is now moved in front of the end face of the guide body 4 and the locking bolt 7R is supported on the right side of the guide body 4 at its engagement 12R.

Fig. 5B zeigt, dass die Weiche bei links anliegender Weichenzunge stumpf aufgefahren wird. Figure 5B shows that the switch is opened bluntly when the switch tongue is on the left.

Dabei wird zuerst auch die nicht-anliegende (=abliegende) rechte Weichenzunge in Richtung auf das ihr zugeordnete Geleis bewegt. Diese Bewegung überträgt sich auf den Gleitkörper 2R, der mittels Sperrbolzen 7R und Schubkante 16R auch den Steckschlüssel nach rechts mitnimmt. Durch die Bewegung des Steckschlüssels 11 nach rechts gelangt die Eintreibkante 30R der Tasche 15R in Wirkverbindung mit der Eintreibfläche 20R des Sperrbolzen 7R. Der Sperrbolzen 7R wird daher hinter die Kontur des Gleitkörpers 2R zurückgezogen und nunmehr ist Formschluß zwischen Gleitkörper 2R und Steckschlüssel 13R hergestellt.In doing so, the non-adjacent (= remote) right switch tongue is first moved in the direction of the track assigned to it. This movement is transmitted to the sliding body 2R, which also takes the socket wrench with it to the right by means of the locking pin 7R and the pushing edge 16R. By moving the socket wrench 11 to the right, the driving edge 30R of the pocket 15R comes into operative connection with the driving surface 20R of the locking pin 7R. The locking pin 7R is therefore behind the contour of the sliding body 2R withdrawn and now a form fit between sliding body 2R and socket wrench 13R is established.

Da der Führungskörper 4 noch durch die Blockierzunge 109R festgelegt ist, wird die Einrastpaarung 113 überwunden. Durch die Bewegung des Steckschlüssels 11 nach rechts gelangt die Eintreibkante 30L der Tasche 15L in Wirkverbindung mit der Eintreibfläche 20L des Sperrbolzen 7L. Der Sperrbolzen 7L wird daher hinter die Kontur des Gleitkörpers 2L zurückgezogen und nunmehr ist der Formschluß der anliegenden Weichenzunge 25L aufgehoben und auch sie kann stumpf aufgefahren werden.Since the guide body 4 is still fixed by the blocking tongue 109R, the latching pair 113 is overcome. By moving the socket wrench 11 to the right, the driving edge 30L of the pocket 15L comes into operative connection with the driving surface 20L of the locking bolt 7L. The locking bolt 7L is therefore withdrawn behind the contour of the sliding body 2L and now the form fit of the adjacent switch tongue 25L is canceled and it can also be opened bluntly.

Der Weichenantrieb gewährleistet, daß alle sicherheitsrelevanten Teile und insbesondere die Sperrbolzen auch bei Normalbetrieb betätigt werden, so daß sie beweglich bleiben und ihre Beweglichkeit ständig überwacht wird. Eine Ausnahme bilden die Sperrbolzen z.B. 7R in der Betätigungsphase nach Fig.5A. In dieser Relativlage des Gleitkörpers 2R und des Steckschlüssels hat der Sperrbolzen in Richtung seiner Gleitführung eine undefinierte Stellung. Um das zu vermeiden, kann der Eingriff 12R und 12L am Führungskörper 4 auch doppelseitig ausgebildet werden als kegeliges Loch bzw. Nut mit spitz zulaufenden Flanken 30, wie dies anhand Fig.3, insbesondere 3B gezeigt und beschrieben ist. Dadurch wird durch jede Relativbewegung zwischen Gleitkörper 2R/2L und Führungskörper der Stellbolzen jedenfalls in seine Neutralstellung eingefahren.The switch drive ensures that all safety-relevant parts and in particular the locking bolts are actuated even during normal operation, so that they remain movable and their mobility is constantly monitored. The locking bolts, e.g. 7R, are an exception in the actuation phase Fig.5A . In this relative position of the sliding body 2R and the socket wrench, the locking bolt has an undefined position in the direction of its sliding guide. In order to avoid this, the engagement 12R and 12L on the guide body 4 can also be formed on both sides as a conical hole or groove with tapering flanks 30, as shown in FIG Fig. 3 , particularly Figure 3B is shown and described. As a result, every relative movement between the sliding body 2R / 2L and the guide body moves the adjusting bolt into its neutral position.

Für Weichen, die mit großer Frequenz befahren werden, sind im genannten StdT Einrichtungen genannt (elektrischer Detektor 26.3 in Fig.3B gegenüber der Kulissenplatte 14 liegend an dem Blockierblock befestigt, der mit Taststiften 26.4 die radiale Relativlage der Einrastwellen abtastet) deren elektrisches Ausgangssignal das Stumpf-Auffahren signalisieren und sodann der Steuereinrichtung 32 des Weichenantriebs aufgegeben, um die Weiche aufzufahren und wieder in ihre Ausgangslage zurückzufahren. Diese Einrichtung wird hier für das Stumpfauffahren überflüssig.
