Abstract

A railroad track brake in which a piston track brake is shifted out of an active state into an inactive state by a track-brake lowering device with a length of structural section extending along the piston track brake and having drag bars attached thereto while engaging the piston track brake. The active and inactive states are produced without contacting the housing of the piston track brake, and the braking process is free of acceleration forces. The drag bars contact the piston track brake only when it is in an inactive state to prevent acceleration forces.

Die am Beginn der Richtungsgleise durch Gleisbremsen verzögerten Waggons beschleunigen sich sonst auf unzulässige Geschwindigkeiten, so dass beim Auflaufen dieser Waggons erhebliche Schäden an den Waggons selbst oder am Ladegut entstehen können.The wagons decelerated at the beginning of the directional tracks by track brakes otherwise accelerate to impermissible speeds, so that when these wagons hit the wagons themselves or the load can be seriously damaged.
Eine Gleisbremse der eingangs beschriebenen Gattung ist bekannt (DE 19635467). Der konstruktive Aufbau der Kolbengleisbremse ist in DE 3031173 beschrieben. Bei der bekannten Gleisbremse sind die längs der Fahrschiene angeordneten Kolbengleisbremsen zwischen einer aktiven und einer inaktiven Stellung um eine sich parallel zur Fahrschiene erstreckende Achse verschwenkbar gelagert und können durch einen Stelltrieb verschwenkt werden. Das Verschwenken der Kolbengleisbremsen in eine inaktive Stellung kann jederzeit erfolgen, also auch dann, wenn sich Laufräder von Schienenfahrzeugen im Bremsenabschnitt befinden. Die Kolbengleisbremsen können aber nur dann in die aktive Stellung verschwenkt werden, wenn sich imA track brake of the type described above is known (DE 19635467). The design of the piston rail brake is described in DE 3031173. In the known track brake, the piston track brakes arranged along the travel rail are pivotably mounted between an active and an inactive position about an axis extending parallel to the travel rail and can be pivoted by an actuator. The piston track brakes can be pivoted into an inactive position at any time, that is to say also when the wheels of rail vehicles are in the brake section. The piston track brakes can only be pivoted into the active position if the
Bremsenabschnitt keine Laufräder von Schienenfahrzeugen befinden, weil sonst die Kolbengleisbremsen seitlich gegen die Laufräder gedrückt werden. Deswegen muß der Bremsenabschnitt zusätzlich mit Hilfe von Gleisschaltmitteln, z.B. in Form eines Gleiskreises überwacht werden. Dadurch entstehen zusätzliche Kosten.Brake section are no wheels of rail vehicles, because otherwise the piston rail brakes are pressed against the side of the wheels. For this reason, the brake section must also be monitored with the aid of track switching means, for example in the form of a track circuit. This creates additional costs.
In der Praxis sind auch Ausführungen bekannt, bei denen ein Pneumatikzylinder parallel zum längsverschieblichen Kolbenrohr der Kolbengleisbremsen angeordnet ist. Die Kolbenstange des Pneumatikzyiinders ist an ihrem Ende hakenförmig ausgebildet und greift über den Kolbenrohrkopf. Anstelle eines Pneumatikzylinders kann auch ein Hydraulikzylinder oder ein kleines Getriebe verwendet werden, um mit einer hakenförmig ausgebildeten Kolbenstange das Kolbenrohr einzuziehen bzw. abzusenken. Die jeweilige Energieversorgung kann für einzelne Kolbengleisbremsen oder auch für Gruppen von z.B. 10 Kolbengleisbremsen erfolgen.

Der Nachteil dieser Ausführung besteht allerdings in der Anordnung einer Vielzahl von Bauteilen, die am Gehäuse der Kolbengleisbremse angebracht werden müssen. Diese Bauteile müssen extrem hohe Beschleunigungskräfte aufnehmen, die beim Auftreffen der Laufräder auf die Kolbenrohrköpfe entstehen. Es wurden Stöße mit 1.000-facher Erdbeschleunigung gemessen.

Aufgabe der Erfindung ist es, eine Gleisbremse der eingangs beschriebenen Gattung so zu verbessern, dass die Kolbengleisbremsen auch dann aus der inaktiven in die aktive Stellung gebracht werden können, wenn sich Laufräder eines Schienenfahrzeuges im Bremsenbereich befinden, wobei gleichzeitig die Funktionalität verbessert und eine bahnfeste, robuste Konstruktion entstehen soll.The object of the invention is to improve a track brake of the type described in the introduction in such a way that the piston track brakes are then also brought from the inactive to the active position can, if there are wheels of a rail vehicle in the brake area, while at the same time improving functionality and creating a track-stable, robust construction.
Diese Aufgabe wird dadurch gelöst, dass die Einrichtung als Absenkvorrichtung ausgebildet ist, die ein sich längs der Kolbengleisbremsen erstreckendes Profil aufweist, an dem Mitnehmerlaschen befestigt sind, welche die Kolbengleisbremsen beaufschlagen. Diese Absenkvorrichtung wird in Höhe der Kolbenrohrköpfe angeordnet. Veränderungen an den Kolbengleisbremsen selbst sind nicht notwendig. Die Mitnehmerlaschen erstrecken sich bis über die Kolbenrohrköpfe und drücken bei Betätigung der Absenkvorrichtung die Kolbenrohre der Kolbengleisbremsen gegen deren Dämpferfederkraft nach unten, bis die Kolbenrohrköpfe der Kolbenrohre eine Stellung eingenommen haben, in der sie von den Laufrädern des Schienenfahrzeuges nicht mehr beaufschlagt werden. In dieser Stellung ist die Gleisbremse wirkungslos und kann ungehindert von Schienenfahrzeugen passiert werden.This object is achieved in that the device is designed as a lowering device, which has a profile extending along the piston track brakes, to which driver plates are attached, which act on the piston track brakes. This lowering device is arranged at the level of the piston tube heads. Changes to the piston rail brakes themselves are not necessary. The driver plates extend over the piston tube heads and, when the lowering device is actuated, press the piston tubes of the piston track brakes down against their damper spring force until the piston tube heads of the piston tubes have reached a position in which they are no longer acted upon by the wheels of the rail vehicle. In this position, the track brake is ineffective and can be passed by rail vehicles unhindered.
Bei einer bevorzugten Ausführung der Erfindung ist das Profil um seine Profilachse drehbar gelagert. Das Profil kann ein Rohr oder ein Vielkantrohr sein. Als Stelltrieb kann vorzugsweise ein elektrischer Rohrmotor eingesetzt werden. Auch andere Antriebe, wie z.B. ein elektrischer Getriebemotor oder ein Linearantrieb kommen mit Seilzug und Umlenkrollen als Stelltrieb infrage, um die Verdrehung in eine aktive und inaktive Stellung zu ermöglichen. Bei einem Linearantrieb mit Seilzug und Umlenkrolle erfolgt die Verdrehung des Profils in die aktive Stellung durch die Einwirkung der Dämpferfederkräfte auf die Mitnehmerlaschen, wenn der Linearantrieb den Seilzug nachläßt.

Other drives, such as an electric geared motor or a linear drive with cable pull and deflection pulleys, can also be used as actuators in order to enable the rotation into an active and inactive position. In the case of a linear drive with cable pull and deflection roller, the profile is rotated into the active position by the action of the damper spring forces on the driving lugs when the linear drive slackens the cable pull.

Bei der bevorzugten Ausführung tragen das Profil und/oder der Rohrmotor Lagerzapfen, die sich in zugeordneten Lagern abstützen. Die Lager sind zweckmäßig an Konsolen angeordnet, die an der Fahrschiene, insbesondere an deren Steg, befestigt sind. Wesentlich für die Funktionalität der Gleisbremse ist, dass die Mitnehmerlaschen in aktiver Stellung der Absenkvorrichtung sich außerhalb des Regellichtraumes für das Schienenfahrzeug befinden, - aber dennoch an den Kolbenrohrköpfen angreifen. Zur Verbesserung der Funktionalität trägt auch bei, wenn die Mitnehmerlaschen an ihren an den Kolbengieisbremsen angreifenden Enden einen Abwälzradius aufweisen, - mit dem sie beim Verdrehen des Profils auf der Oberseite der Kolbenrohrköpfe gleichsam abrollen.In the preferred embodiment, the profile and / or the tubular motor carry trunnions which are supported in associated bearings. The bearings are expediently arranged on brackets which are fastened to the running rail, in particular to its web. It is essential for the functionality of the track brake that the driver plates are in the active position of the lowering device outside the standard light room for the rail vehicle, but still act on the piston tube heads. The functionality also improves if the driver plates have a rolling radius at their ends engaging the piston cast iron brakes - with which they roll, as it were, on the top of the piston tube heads when the profile is rotated.
Das Profil ist zweckmäßig mit den Mitnehmerlaschen zwischen Gleismitte und Kolbengleisbremse im Hubbereich der Kolbenrohre angeordnet.The profile is expediently arranged with the driver lugs between the middle of the track and the piston track brake in the stroke area of the piston tubes.
In weiterer Ausgestaltung können die Mitnehmerlaschen mit Befestigungsschrauben und dadurch vorgespannten Tellerfedern am Profil befestigt sein. Wegen der leichten Austauschbarkeit von Mitnehmerlaschen hat das auch den Vorteil, dass schlagartige Belastungen des Stelltriebes verhindert werden. Derartige schlagartige Belastungen entstehen, wenn gleichzeitig mit der Betätigung der Absenkvorrichtung der Bremsenabschnitt von Schienenfahrzeugen befahren wird und die Mitnehmerlaschen in einer Zwischenstellung von hochschnellenden Kolbenrohren beaufschlagt werden. Die Mitnehmerlaschen bestehen zweckmäßigerweise aus gehärtetem Flachstahl und können eine Dicke von ca. 10 - 20 mm sowie eine Breite von ca. 70 - 120 mm aufweisen. Die Länge der Mitnehmerlaschen kann 100 - 200 mm betragen, um genügend Überdeckung mit den Kolbenrohrköpfen zu haben, wenn die Kolbengleisbremsenabstände stärker differieren.In a further embodiment, the driving lugs can be fastened to the profile with fastening screws and thus pre-tensioned disc springs. Because of the easy interchangeability of drive plates, this also has the advantage that sudden loads on the actuator are prevented. Such sudden loads occur when the brake section of rail vehicles is operated simultaneously with the actuation of the lowering device and the driving plates are acted upon in an intermediate position by high-speed piston tubes. The drive plates advantageously consist of hardened flat steel and can have a thickness of approximately 10-20 mm and a width of approximately 70-120 mm. The length of the driver plates can be 100 - 200 mm to ensure sufficient overlap with the To have piston tube heads if the piston track brake distances differ more.
Anstelle einer Drehbewegung, die das Profil der Absenkvorrichtung ausführt, könnte auch eine Hubbewegung die gleiche Aufgabe erfüllen. Hierzu wird das Profil mit senkrechten Führungen und/oder mit Hubelementen, z.B. Verstelispindeln oder Hydraulikzylindern versehen, die ein senkrechtes Verstellen bzw. Herunterziehen der Kolbenrohre durch das mit Mitnehmerlaschen besetzte Profil ermöglichen.Instead of a rotary movement that executes the profile of the lowering device, a lifting movement could also perform the same task. For this purpose, the profile with vertical guides and / or with lifting elements, e.g. Provide adjusting spindles or hydraulic cylinders that allow the piston tubes to be adjusted vertically or pulled down by means of the profile fitted with driving plates.
Im übrigen können verstellbare Endschalter zum Einstellen und Überwachen der aktiven bzw. der inaktiven Stellung sowie einer Wartungsstellung der Kolbengleisbremsen vorgesehen sein.In addition, adjustable limit switches can be provided for setting and monitoring the active or inactive position and a maintenance position of the piston track brakes.
Es kann außerdem günstig sein, dass das Profil als Teleskopprofil ausgebildet ist und/oder die Mitnehmerlaschen auf dem längs der Kolbengleisbremsen sich erstreckenden Profil an beliebiger Stelle bzw. in beliebigen Abständen klemmbar angeordnet sind.It can also be favorable for the profile to be designed as a telescopic profile and / or for the catch tabs to be clamped on the profile extending along the piston rail brakes at any point or at any spacing.
Bei der Montage der erfindungsgemäßen Gefälleausgleichsbremsen können die Bohrungen im Schienensteg für die Aufnahme der Kolbengleisbremsen und die Lagerkonsolen der Absenkvorrichtung in den jeweiligen Schweilenfächern gebohrt werden, ohne die Schwellenteilung zu berücksichtigen. Nach dem Anschrauben der Kolbengleisbremse wird das Teleskopprofil angeschraubt, wobei das Teleskopprofil soweit auseinander gezogen wird, dass die beiden Lagerkonsolen in die dafür vorgesehenen Bohrungen passen. Danach erfolgen die Ausrichtung und das Festklemmen der Mitnehmerlaschen am Teleskopprofil nach den tatsächlichen Einbaupositionen der Kolbengleisbremsen.

Erfindungsgemäß ist es auch möglich, entweder nur das Teleskopprofil zu verwenden oder bei Verzicht auf das Teleskopprofil die Mitnehmerlaschen auf dem Profil in beliebigen Abständen anzuklemmen.omitted. According to the invention, it is also possible to either use only the telescopic profile or, if the telescopic profile is dispensed with, to clamp the catch tabs on the profile at any desired intervals.
Das Teleskopprofil kann aus zwei oder mehreren ineinander verschiebbaren Vierkantrohren oder sonstigen Vielkantrohren mit beliebiger Form bestehen. Wichtig ist hierbei, dass die einzelnen Rohre des Teleskopprofiles sich nicht gegeneinander verdrehen können. An den jeweiligen Kopfseiten des Teleskopprofiles sind Lagerzapfen mit Lagern angeordnet, die auf Lagerkonsolen geschraubt sind. Entsprechend den Bohrungsstichmaßen für die Befestigung der Lagerkonsoien im Schienensteg lässt sich die Länge des Teleskopprofiles problemlos einstellen, bevor es festgeschraubt wird.The telescopic profile can consist of two or more square tubes that can be slid into one another or other polygonal tubes of any shape. It is important that the individual tubes of the telescopic profile cannot twist against each other. On the respective head sides of the telescopic profile, bearing journals with bearings are screwed onto bearing brackets. The length of the telescopic profile can be easily adjusted in accordance with the hole dimensions for the mounting of the bearing bracket in the rail web before it is screwed down.
Die Mitnehmerlaschen können vorzugsweise mit Hilfe von U-förmig ausgebildeten Befestigungsschellen, die der äußeren Kontur des Teleskopprofiles angepasst sind, an das Profil angeklemmt werden. Die Mitnehmerlaschen können winkelförmig ausgebildet sein, wobei ein Schenkel über eine kleine drehbare Rolle das Kolbenrohr derThe drive tabs can preferably be clamped to the profile with the aid of U-shaped fastening clips which are adapted to the outer contour of the telescopic profile. The drive tabs can be angular, with one leg of the piston tube of the small rotatable roller
Kolbengleisbremse beaufschlagt. Der andere Schenkel ist als Grundplatte ausgebildet und stützt sich auf einer Seitenfläche des Teleskopprofiles ab. Die Grundplatte der Mitnehmertasche ragt mit ihren Kanten über das Teleskopprofil hinaus, damit die Enden der Schellen, die das Profil umschliessen, mit ihren offenen Enden mit der Grundplatte verschraubt werden können. Vorzugsweise zwei U-förmig gebogene Schellen, die das Profil umschliessen, haben an den offenen Enden Gewinde, sodass eine Verschraubung mit der Grundplatte und dadurch ein Festklemmen der Mitnehmerlaschen an jeder beliebigen Stelle des Teleskopprofiles möglich ist. Stark unterschiedliche Einbaupositionen der Kolbengleisbremsen können so ohne zusätzlichen Aufwand ausgeglichen werden. - 7 -Piston track brake applied. The other leg is designed as a base plate and is supported on a side surface of the telescopic profile. The edges of the base plate of the drive pocket protrude beyond the telescopic profile so that the ends of the clamps that surround the profile can be screwed to the base plate with their open ends. Preferably two U-shaped clamps, which enclose the profile, have threads at the open ends, so that they can be screwed to the base plate and thereby clamp the drive tabs at any point on the telescopic profile. Very different installation positions of the piston rail brakes can be compensated for without additional effort. - 7 -
In einer bevorzugten Ausgestaltung können zwischen einer Grundplatte der Mitnehmerlasche und einer Seitenfläche des Teleskopprofiles ein oder mehrere Dämpfungsplatten angeordnet sein, um eventuell schlagartig auftretende Beanspruchungen dämpfen zu können. Das Teleskopprofil kann auch mehrstufig ausgebildet bzw. an beiden Enden eines Profilrohres vorhanden sein.In a preferred embodiment, one or more damping plates can be arranged between a base plate of the driving lug and a side surface of the telescopic profile in order to be able to dampen suddenly occurring stresses. The telescopic profile can also be designed in several stages or be present at both ends of a profile tube.
Die mit der Erfindung erreichten Vorteile werden zusammengefaßt darin gesehen, dass die Kolbengieisbremsen unabhängig davon, ob sie gerade von dem Laufrad eines Schienenfahrzeuges niedergedrückt sind oder nicht, aus einer inaktiven in eine aktive Stellung oder umgekehrt gebracht werden können. Wird eine Kolbengleisbremse von einem sich darüber befindlichen Laufrad am selbsttätigen Ausschieben gehindert, so kann die Absenkvorrichtung trotzdem betätigt werden und alle übrigenThe advantages achieved with the invention are summarized in the fact that the piston gas brakes, regardless of whether they are currently depressed by the wheel of a rail vehicle or not, can be brought from an inactive to an active position or vice versa. If a piston rail brake is prevented from automatically pushing out by an impeller located above it, the lowering device can still be operated and all others
Kolbengleisbremsen können eine aktive Stellung einnehmen. Die Mitnehmerlaschen und das Profil sind außerhalb des Regellichtraumes für das Schienenfahrzeug angeordnet, so dass diese Bauteile nicht mit den Laufrädern des Schienenfahrzeuges in Berührung kommen können. Eine Überwachung des Bremsenabschnittes mit Gleisschaltmitteln kann entfallen.Piston track brakes can take an active position. The driver tabs and the profile are arranged outside the standard light space for the rail vehicle, so that these components cannot come into contact with the wheels of the rail vehicle. Monitoring of the brake section with track switching means can be omitted.
Die Erfindung wird anhand der beigefügten Figuren 1 bis 5 beispielsweise näher erläutert:The invention is explained in more detail, for example, with the aid of the attached FIGS. 1 to 5:

Zu dem in der Zeichnung dargestellten Abschnitt eines Richtungsgieises gehören Fahrschienen 1 , 2, die in üblicher weise auf Gleisschwellen 3 mit Rippenplatten 19 und Hakenschrauben 20 befestigt sind (Fig. 1). An den Fahrschienen 1 sind jeweils in einem Schwellenfach 22 zweiThe section of a directional track shown in the drawing includes rails 1, 2 which are fastened in a conventional manner to track sleepers 3 with ribbed plates 19 and hook screws 20 (FIG. 1). There are two in each sleeper compartment 22 on the rails 1
Kolbengleisbremsen 4 im Schienensteg 23 mit Schrauben 24 befestigt. Sie entsprechen sonst einem an sich bekannten Aufbau. Gefäileausgleichsbremsen sind zweckmäßig über drei bis fünf Schwellenfächer 22 angeordnet.Piston track brakes 4 fastened in the rail web 23 with screws 24. Otherwise they correspond to a structure known per se. Compensation brakes are expediently arranged over three to five sleeper compartments 22.
In der dargestellten Ausführung mit fünf besetzten Schwellenfächern 22 wird parallel zur Fahrschiene 1 ein als drehbar gelagertes Achtkantrohr 7 ausgebildetes Profil, das mit Mitnehmeriaschen 8 besetzt ist, angeordnet.In the illustrated embodiment with five occupied sleeper compartments 22, a profile which is configured as a rotatably mounted octagonal tube 7 and which is equipped with driving lugs 8 is arranged parallel to the travel rail 1.
An einem Ende des drehbar gelagerten Achtkantrohres ist einAt one end of the rotatable octagonal tube is a
Lagerzapfen 15 angebracht. An dem anderen Ende des Achtkantrohres ist ein elektrischer Rohrmotor 13 angeordnet, der ebenfalls einen Lagerzapfen 15 besitzt. Beide Lagerzapfen 15 stützen sich in drehbaren Lagern 14 ab, die auf Konsolen 16 aufgeschraubt oder angeschweißt sind. Die Konsolen 16 werden im Schienensteg 23 angeschraubt. Es ist selbstverständlich auch möglich, die Konsolen 16 auf den Gleisschwellen 3 abzustützen.Bearing journal 15 attached. At the other end of the octagonal tube, an electric tubular motor 13 is arranged, which also has a bearing pin 15. Both journals 15 are supported in rotatable bearings 14 which are screwed or welded onto brackets 16. The brackets 16 are screwed into the rail web 23. It is of course also possible to support the consoles 16 on the track sleepers 3.
Auf dem Achtkantrohr 7 sind auf einer Seitenfläche 25 Mitnehmerlaschen 8 mit jeweils zwei Durchgangs-Befestigungsschrauben 9 aufgeschraubt (Fig. 2). Die Befestigungsschrauben 9 sind mit Tellerfedern 11 durch eine - y -On the octagonal tube 7 25 drive tabs 8 are screwed on each side surface with two through-fastening screws 9 (Fig. 2). The mounting screws 9 are with disc springs 11 through a - y -
Verspannung zwischen Mutter 12 und dem Achtkantrohr 7 vorgespannt, um bei schlagartiger Beanspruchung der Mitnehmerlaschen 8 eine Dämpfung zu erzielen. Die Mitnehmerlaschen 8 bestehen aus gehärtetem Stahl und haben zum Kolbenrohrkopf 21 hin einen Radius 17, um sich besser abwälzen zu können. In den Mitnehmerlaschen 8 sind für die Befestigungsschrauben 9 Langlöcher 10 vorgesehen, damit nach der Gleismontage noch Justierungen in Längsrichtung zur Fahrschiene 1 möglich sind oder beim Verschleiß der Mitnehmerlaschen 8 ein neuer Kontaktpunkt eingestellt werden kann, was die Einsatzdauer der Mitnehmerlaschen 8 beträchtlich verlängert.Tension between the nut 12 and the octagonal tube 7 is prestressed in order to achieve damping in the event of sudden stress on the driving plates 8. The driver plates 8 are made of hardened steel and have a radius 17 towards the piston tube head 21 in order to be able to roll off better. Elongated holes 10 are provided in the catch plates 8 for the fastening screws 9, so that adjustments in the longitudinal direction to the rail 1 are still possible after the track assembly or a new contact point can be set when the catch plates 8 wear, which considerably extends the service life of the catch plates 8.
In der aktiven Stellung der Gefälleausgieichsbremse (Fig. 2) ist das Laufrad 5 mit Spurkranz 6 eines nicht dargestellten Schienenfahrzeuges mit gestrichelten Linien dargestellt, wie es den Kolbenrohrkopf 21 des Kolbenrohres 18 befährt.In the active position of the gradient compensating brake (FIG. 2), the impeller 5 with the flange 6 of a rail vehicle (not shown) is shown with dashed lines as it travels the piston tube head 21 of the piston tube 18.
Es kommt dabei zu keiner Behinderung durch die Mitnehmerlaschen 8 und das Achtkantrohr 7.There is no hindrance from the driver plates 8 and the octagonal tube 7.
Zur Erreichung der inaktiven Stellung der Gefälleausgieichsbremse (Fig. 3) wird das mit Mitnehmerlaschen 8 bestückte Achtkantrohr 7 durch Betätigung des elektrischen Rohrmotors 13 in Richtung des Pfeiles 26 verdreht. Dabei nehmen die Mitnehmerlaschen 8 die längsverschieblichen Kolbenrohre 18 mit, bis die (in Fig. 3) dargestellte Position erreicht ist. Das Laufrad 5 mit Spurkranz 6 kann damit ungehindert die Gleisbremse passieren. Nicht dargestellte sind verstellbare Endschalter zum Einstellen und Überwachen der aktiven und inaktiven Stellung der Kolbengleisbremse 4.In order to achieve the inactive position of the gradient compensating brake (FIG. 3), the octagonal tube 7 equipped with driving lugs 8 is rotated in the direction of arrow 26 by actuation of the electric tubular motor 13. The driver plates 8 take the longitudinally displaceable piston tubes 18 with them until the position shown in FIG. 3 is reached. The impeller 5 with flange 6 can thus pass the track brake unhindered. Adjustable limit switches for setting and monitoring the active and inactive position of the piston track brake 4 are not shown.
Die Drehrichtung des Rohrmotors 13 erfolgt zweckmäßigerweise nur in Richtung des Drehpfeiles 26. Eine Umkehrung der Drehrichtung entgegen - 10 -The direction of rotation of the tubular motor 13 is expediently only in the direction of the arrow 26. The direction of rotation is reversed in the opposite direction - 10 -
des Drehrichtungspfeiles 26 ist ebenfalls möglich, aber elektrisch einfacher ist die Beibehaltung der Drehrichtung, wenn die Gleitbremse von der inaktiven Stellung (Fig. 3) wieder in die aktive Stellung (Fig. 2) gebracht werden soll. Nach dem Freigeben der Kolbenrohrköpfe 21 durch die Mitnehmerlaschen 8 schieben die Kolbenrohre 18 selbsttätig durch die innen in den Kolbenrohren 18 befindlichen Dämpfer aus, während das mit Mitnehmerlaschen 8 besetzte Achtkantrohr 7 weiterdreht und wieder die Ausgangsposition (Fig. 2) einnimmt.the direction of rotation arrow 26 is also possible, but maintaining the direction of rotation is electrically simpler if the sliding brake is to be brought back from the inactive position (FIG. 3) to the active position (FIG. 2). After the piston tube heads 21 have been released by the driving lugs 8, the piston tubes 18 automatically slide out through the dampers located inside the piston tubes 18, while the octagonal tube 7, which is equipped with driving lugs 8, continues to rotate and returns to the starting position (FIG. 2).
Nicht dargestellt ist eine Position der Mitnehmerlaschen 8 in der dieNot shown is a position of the driver tabs 8 in which the
Kolbenrohrköpfe 21 freigegeben sind, sodass zu Wartungszwecken die Kolbenrohre 18 aus den Kolbengleisbremsen 4 herausgezogen werden können. Die Wartungsposition wird ebenfalls durch einen Endschalter überwacht und kann bei Bedarf aktiviert werden.Piston tube heads 21 are released so that the piston tubes 18 can be pulled out of the piston rail brakes 4 for maintenance purposes. The maintenance position is also monitored by a limit switch and can be activated if necessary.
Die nach Figuren 4 und 5 an einer Seitenfläche 27 des Teleskopprofiles 29 aufgeklemmte Mitnehmeriasche 28 ist winkelförmig ausgebildet. Der Schenkel 32 der Mitnehmerlasche 28 beaufschlagt über eine kleine Rolle 34 das Kolbenrohr 18 der Kolbengleisbremse 4. Der Schenkel 33 der Mitnehmerlasche 28 dient als Grundplatte zur Verschraubung mit den das Teleskopprofil 29 U-förmig umschliessenden Befestigungsschellen 35 (Fig. 5). Diese Befestigungsschellen 35 haben an ihren offenen Enden Gewinde 36, sodass mit einer Mutter 37 nach entsprechender Ausrichtung in Richtung des Pfeiles 38 die erforderliche Klemmkraft zur Fixierung der Mitnehmerlasche 28 auf dem Teleskopprofil 29 erzeugt werden kann. Zwischen der Grundplatte 38 und der Seitenfläche 27 ist eine Dämpfungsplatte 40 angeordnet, um eventuell schlagartige Beanspruchungen der Mitnehmeriasche 28 durch die Kolbengleisbremse 4 zu vermeiden. In Fig. 5 besteht das Teleskopprofil 29 aus einem größeren Vierkantrohr 30 und einem kleineren Vierkantrohr 31 , das in Richtung des Pfeiles 39 in weiten Bereichen verschiebbar ist und damit große Stichmaßdifferenzen infolge unregelmäßiger Schwellenteilungen überbrücken kann. Die Kopfseiten der Vierkantrohre 30 und 31 sind jeweils mit einer Kopfplatte 41 verschlossen. Diese bilden die Aufnahme für die Lagerzapfen 42, die sich in einem drehbaren Lager 43 abstützen (Fig. 4) und auf Konsolen 44 angeschraubt oder angeschweißt sind. Die Konsolen 44 werden im Schienensteg 45 der Fahrschiene 1 , 2 angeschraubt. Die Schraubverbindung ist zeichnerisch nicht dargestellt. Es ist selbstverständlich auch möglich, die Konsolen 44 auf nicht dargestellten Gleisschwellen abzustützen. The drive plate 28 clamped on a side surface 27 of the telescopic profile 29 according to FIGS. 4 and 5 is of an angular design. The leg 32 of the driving plate 28 acts on the piston tube 18 of the piston track brake 4 via a small roller 34. The leg 33 of the driving plate 28 serves as a base plate for screwing with the fastening clips 35 which surround the telescopic profile 29 in a U-shape (FIG. 5). These fastening clamps 35 have threads 36 at their open ends, so that the necessary clamping force for fixing the driving lug 28 on the telescopic profile 29 can be generated with a nut 37 after appropriate alignment in the direction of the arrow 38. A damping plate 40 is arranged between the base plate 38 and the side surface 27, in order to avoid any sudden stresses on the driving plate 28 by the piston track brake 4. In Fig. 5, the telescopic profile 29 consists of a larger square tube 30 and a smaller square tube 31, which is displaceable in the direction of arrow 39 over a wide range and can therefore bridge large gauge differences due to irregular threshold divisions. The top sides of the square tubes 30 and 31 are each closed with a top plate 41. These form the receptacle for the bearing journal 42, which is supported in a rotatable bearing 43 (FIG. 4) and is screwed or welded onto brackets 44. The brackets 44 are screwed into the rail web 45 of the rail 1, 2. The screw connection is not shown in the drawing. It is of course also possible to support the consoles 44 on track sleepers, not shown.
