Abstract

The invention relates to a rail brake system for marshalling yards, having at least one group of brake elements (5) which are attached one behind the other to the rail web and can be moved out of an inactive home position into an active braking position using an electric control, at least one control line which is common to all the brake elements (5) and to which actuator elements (9) which are assigned to the brake elements (5) are connected being provided. The electric connection power of such a rail brake system is substantially reduced by providing a locking line (V) and an unlocking line (E), by assigning to each actuator element (9) a locking switch (II) which is actuated thereby and arranged in the locking line (V), and an unlocking switch (I) which is actuated thereby and arranged in the unlocking line (E), and by connecting the actuator elements (9) electrically into the circuit which leads from the switches to a return line (R) in such a way that the actuator elements (9) are actuated successively in a cascade-like manner. Alternatively, the invention provides for the actuator elements (9) to engage on associated locking elements (8) which can be moved between a position of rest in which they are disengaged from the brake elements (5), and a locking position in which they hold the brake elements (5) in the inactive home position.

Description

Die Erfindung betrifft eine Gleisbremsanlage für Rangierbahnhöfe mit zumindest einer Gruppe aus mehreren hintereinander am Schienensteg befestigten Bremselementen, die mit einer elektrischen Steuerung aus einer inaktiven Grundstellung in eine aktive Bremsstellung bewegbar sind, wobei zumindest eine allen Bremselementen gemeinsame Leitung vorgesehen ist, an die den Bremselementen zugeordnete Stellelemente angeschlossen sind.The invention relates to a track brake system for marshalling yards with at least one group of a plurality of brake elements which are fastened one behind the other on the rail web and which can be moved from an inactive basic position into an active braking position by means of an electrical control, at least one line being provided to all the braking elements and to which the braking elements are assigned Control elements are connected.

Aus der Praxis sind Bremselemente bekannt, die an den Schienensteg angeschraubt sind und durch den Spurkranz eines rollenden Rades gegen die Wirkung eines Kolbens niedergedrückt werden. Die Bremselemente bzw. ihre Kolben sind auf eine bestimmte Ansprechgeschwindigkeit eingestellt. Ist die Geschwindigkeit des das Bremselement überrollenden Rades größer als die Ansprechgeschwindigkeit, dann läßt sich der Kolben nur mit großer Kraft eindrücken. Dabei wird Bremsarbeit geleistet, die als Geschwindigkeitsenergie dem überrollenden Rad entzogen wird. Ist die Geschwindigkeit des das Bremselement überrollenden Rades jedoch kleiner als die Ansprechgeschwindigkeit, dann läßt sich der Kolben relativ leicht eindrücken und dem überrollenden Rad wird nur eine kleine Energiemenge entzogen. Da die Bremselemente keine externe Steuerung besitzen, wird jedes überrollende Rad gebremst, wenn dessen Geschwindigkeit über der Ansprechgeschwindigkeit liegt. Das ist nicht immer erwünscht, zum Beispiel bei der Zugbildung aus einem Richtungsgleis oder bei Gegenausfahrten oder bei Einlauf leichter, langer Wagengruppen oder beim Einlauf in einen nur schwach geneigten Bereich.Brake elements are known from practice, which are screwed onto the rail web and are pressed against the action of a piston by the wheel flange of a rolling wheel. The brake elements or their pistons are set to a certain response speed. If the speed of the wheel rolling over the braking element is greater than the response speed, the piston can only be pressed in with great force. Braking work is carried out, which is extracted from the rolling wheel as speed energy. However, if the speed of the wheel rolling over the braking element is lower than the response speed, the piston can be pressed in relatively easily and only a small amount of energy is withdrawn from the rolling wheel. Since the braking elements have no external control, each wheel that rolls over is braked if its speed is above the response speed. This is not always desirable, for example when forming trains from a directional track or when making counter-exits or when entering light, long wagon groups or when entering a slightly inclined area.

Diese Nachteile vermeidet eine Gleisbremsanlage der eingangs beschriebenen Gattung (DE 0S 32 01 093), bei der jedem Bremselement ein Stellelement zugeordnet ist, mit dem das Bremselement aus seiner aktiven Bremsstellung, bei der es vom überrollenden Rad erfaßt wird, in eine inaktive Grundstellung bewegt werden kann, bei der es vom überrollenden Rad nicht erfaßt wird, und wobei alle Stellelemente an eine gemeinsame Steuerleitung angeschlossen sind. Über die Steuerleitung wird die zur Verstellung der Stellelemente benötigte Energie übertragen. Wenn alle Bremselemente einer Gruppe aus ihrer inaktiven Grundstellung in die aktive Bremsstellung oder umgekehrt bewegt werden sollen, muß eine verhältnismäßig große Energiemenge übertragen werden. Das setzt eine große Anschlußleistung voraus, denn systembedingt steht zur Verstellung der Stellelemente nur eine kurze Zeit von wenigen Sekunden zur Verfügung.These disadvantages are avoided by a track brake system of the type described at the outset (DE 0S 32 01 093), in which each brake element is assigned an actuating element with which the brake element is moved from its active braking position, in which it is detected by the rolling wheel, to an inactive basic position can, in which it is not detected by the rolling wheel, and wherein all actuators are connected to a common control line. The energy required to adjust the control elements is transmitted via the control line. If all brake elements of a group are out of their inactive Basic position to be moved to the active braking position or vice versa, a relatively large amount of energy must be transmitted. This requires a large connected load, because the system only allows a short time of a few seconds to adjust the control elements.

Aufgabe der Erfindung ist es, bei einer Gleisbremsanlage der eingangs beschriebenen Gattung die elektrische Anschlußleistung zu reduzieren.The object of the invention is to reduce the electrical connection power in a track brake system of the type described in the introduction.

Diese Aufgabe wird dadurch gelöst, daß eine Verriegelungsleitung und eine Entriegelungsleitung vorgesehen sind, daß jedem Stellelement ein davon betätigbarer, in der Verriegelungsleitung angeordneter Verriegelungsschalter sowie ein davon betätigbarer, in der Entriegelungsleitung angeordneter Entriegelungsschalter zugeordnet ist, wobei die Verriegelungsschalter in Entriegelungsstellung an eine gemeinsame Rückleitung angeschlossen sind sowie in Verriegelungsstellung die benachbarten Abschnitte der Verriegelungsleiter verbinden und wobei die Entriegelungsschalter im Verriegelungszustand an die gemeinsame Rückleitung angeschlossen sind und im Entriegelungszustand die benachbarten Abschnitte der Entriegelungsleitung verbinden, und daß die Stellelemente elektrisch in die von den Schaltern zur Rückleitung führenden Stromkreise geschaltet sind. Damit ist praktisch eine Kaskadenschaltung verwirklicht. Sollen zum Beispiel die Bremselemente der Gruppe aus ihrer aktiven Bremsstellung in die inaktive Grundstellung verstellt werden, dann wird der Verriegelungsleitung elektrische Energie zugeführt. Der dem ersten Bremselement zugeordnete Verriegelungsschalter liegt an der Rückleitung an, so daß der Stromkreis für das Stellelement dieses ersten Bremselementes geschlossen ist. Das Bremselement wird in die inaktive Grundstellung überführt und sein zugeordneter Verriegelungsschalter verbindet dann die benachbarten Abschnitte der Verbindungsleitung, so daß auch das nächste Bremselement in die inaktive Grundstellung überführt wird, - und so weiter fort, bis alle Bremselemente der Gruppe in die inaktive Grundstellung überführt sind. Entsprechendes gilt, wenn die Bremselemente aus der inaktiven Grundstellung in die aktive Bremsstellung überführt werden, wobei dann elektrische Energie über die Entriegelungsleitung zugeführt wird. Solange die betreffende Leitung unter Strom steht, werden einzelne Bremselemente, die sich aus welchen Gründen auch immer zurückgestellt haben, automatisch wieder in die gewünschte Stellung zurückgeführt, weil beim Verstellen der Bremselemente auch die Schalter bewegt werden. Die Anschlußleistung ist gegenüber dem Stand der Technik wesentlich verringert, weil über die Verriegelungsleitung bzw. die Entriegelungsleitung nur die zum Betätigen jeweils eines Stellelementes erforderliche Energiemenge übertragen werden muß.This object is achieved in that a locking line and an unlocking line are provided that each actuating element is assigned a locking switch which can be actuated and which is arranged in the locking line and an unlocking switch which can be actuated and is arranged in the unlocking line, the locking switch being connected to a common return line in the unlocking position are and in the locked position connect the adjacent sections of the locking conductors and the unlocking switches are connected to the common return line in the locked state and connect the adjacent sections of the unlocking line in the unlocked state, and that the actuating elements are electrically connected to the circuits leading from the switches to the return line. A cascade connection is thus practically implemented. If, for example, the brake elements of the group are to be moved from their active braking position to the inactive basic position, then electrical energy is supplied to the locking line. The locking switch assigned to the first braking element is applied to the return line, so that the circuit for the actuating element of this first braking element is closed. The braking element is transferred to the inactive basic position and its associated locking switch then connects the adjacent sections of the connecting line, so that the next braking element is also transferred to the inactive basic position, and so on until all the braking elements of the group have been transferred to the inactive basic position . The same applies if the braking elements are transferred from the inactive basic position to the active braking position, electrical energy then being supplied via the unlocking line. As long as the line in question is live, individual brake elements, which for whatever reason have reset, are automatically returned to the desired position because the switches are also moved when the brake elements are adjusted. The connected load is essential compared to the prior art reduced because only the amount of energy required to actuate one control element has to be transmitted via the locking line or the unlocking line.

Vorzugsweise weisen die Stellelemente eine im Stromkreis liegende Spule auf. Dabei kann in jedem der mit der Verriegelungsleitung bzw. der Entriegelungsleitung gebildeten Stromkreise eine Spule angeordnet sein. Es ist aber auch möglich, in jedem der mit der Verriegelungsleitung oder der Entriegelungsleitung gebildeten Stromkreise eine Spule anzuordnen und im anderen, dem jeweiligen Stellelement zugeordneten Stromkreis eine mit der Spule verbundene Diode anzuordnen.The control elements preferably have a coil located in the circuit. A coil can be arranged in each of the circuits formed with the locking line or the unlocking line. However, it is also possible to arrange a coil in each of the circuits formed with the locking line or the unlocking line and to arrange a diode connected to the coil in the other circuit associated with the respective actuating element.

Eine alternative Ausführung der Erfindung ist im Anspruch 5 angegeben. Insbesondere sollte jedes Verriegelungselement in Verriegelungsstellung auf der Oberseite des Bremselementes vorzugsweise über waagerecht angeordneten zylindrische Rollen abgestützt sein.An alternative embodiment of the invention is specified in claim 5. In particular, each locking element should be supported in the locking position on the upper side of the braking element, preferably via horizontally arranged cylindrical rollers.

Die erfindungsgemäße Anordnung hat den Vorteil, daß die Stellelemente und die Verriegelungselemente nicht die Kolbenkraft des Bremselementes überwinden müssen. Befinden sich die Bremselemente in der aktiven Bremsstellung und sollen sie in die inaktive Grundstellung überführt werden, dann geschieht das durch den Spurkranz des ersten die Bremselemente überrollenden Rades. Hat ein Bremselement seine inaktive Grundstellung erreicht, dann wird es vom Verriegelungselement erfaßt und gehalten. Dadurch kann die Anschlußleistung weiter reduziert werden.The arrangement according to the invention has the advantage that the actuating elements and the locking elements do not have to overcome the piston force of the braking element. If the brake elements are in the active braking position and are to be transferred to the inactive basic position, this is done by the wheel flange of the first wheel that rolls over the braking elements. If a braking element has reached its inactive basic position, it is gripped and held by the locking element. This can further reduce the connected load.

Federkraft und Remanenzkraft des Permanentmagneten sind so ausgelegt, daß ihre auf das Stellelement bzw. das Verriegelungselement einwirkenden Kräfte an einem Kipp-Punkt zwischen der Grundstellung und der Bremsstellung gleich sind, so daß die Stellelemente bzw. die Verriegelungselemente in stabilen Endlagen gehalten werden.The spring force and remanence force of the permanent magnet are designed so that their forces acting on the control element or the locking element at a tilt point between the basic position and the braking position are the same, so that the actuating elements or the locking elements are held in stable end positions.

Die in der Zeichnung wiedergegebene Schiene 1 gehört zu einer Gleisbremsanlage für Rangierbahnhöfe. Die Schiene 1 wird von einem Rad 2 mit Spurkranz 3 überrollt. An den Schienensteg ist ein Gehäuse 4 für den nicht dargestellten Kolben eines Bremselementes 5 angeschraubt. Das Bremselement 5 ist mit durchgezogenen Linien in einer inaktiven Grundstellung, bei der es vom Spurkranz 3 des überrollenden Rades nicht oder nur im Toleranzbereich erfaßt wird, und mit gestrichelten Linien in einer aktiven Bremsstellung gezeichnet, bei der es vom Spurkranz 3 des überrollenden Rades 2 gegen die Wirkung seines nicht dargestellten Kolbens niedergedrückt wird. In einem außenseitig an das Gehäuse 4 angeschlossenen weiteren Gehäuse 6, das zum Bremselement 5 hin teilweise offen ist, ist um eine horizontale Achse 7 schwenkbar ein Verriegelungselement 8 gelagert, das mit ausgezogenen Linien in einer Verriegelungsstellung wiedergegeben ist, bei der es sich auf der Oberseite des niedergedrückten Bremselementes 5 abstützt, und mit gestrichelten Linien in einer inaktiven Stellung, bei der es praktisch in das Gehäuse 6 eingeschwenkt ist und dabei die Bewegung des Bremselementes 5 nicht behindert.The rail 1 shown in the drawing belongs to a track braking system for marshalling yards. The rail 1 is overrun by a wheel 2 with a flange 3. A housing 4 for the piston, not shown, of a braking element 5 is screwed onto the rail web. The braking element 5 is drawn with solid lines in an inactive basic position, in which it is not detected by the wheel flange 3 of the rolling wheel or only within the tolerance range, and with dashed lines in an active braking position, in which it is opposed by the wheel flange 3 of the rolling wheel 2 the effect of its piston, not shown, is depressed. In a further housing 6, which is connected to the outside of the housing 4 and is partially open towards the braking element 5, a locking element 8 is pivotally mounted about a horizontal axis 7, which locking element 8 is shown in solid lines in a locking position in which it is on the top of the depressed brake element 5, and with dashed lines in an inactive position in which it is practically pivoted into the housing 6 and does not hinder the movement of the brake element 5.

Am Verriegelungselement 8 greift ein als Stellstange ausgebildetes Stellelement 9 an, das am anderen Ende auf einer Druckfeder 10 abgestützt ist und im übrigen in einem Permanentmagneten 11 mit zugeordneter Spule geführt ist.An actuating element 9 designed as an actuating rod acts on the locking element 8, which is supported at the other end on a compression spring 10 and is guided in a permanent magnet 11 with an associated coil.

Am Verriegelungselement 8 greift außerdem ein Schalthebel 12 zur Betätigung eines Mehrfach-Schalters 13 an. Zu diesem Mehrfach-Schalter führen Leitungen 14, die über eine Kabeldurchführung 15 in das Gehäuse 6 eingeführt sind.A shift lever 12 for actuating a multiple switch 13 also acts on the locking element 8. Lines 14, which are introduced into the housing 6 via a cable bushing 15, lead to this multiple switch.

Im Schaltbild der Figur 2 sind mehrere Einheiten 1 bis n dargestellt. Jede Einheit repräsentiert ein Bremselement 5 mit den in Figur 1 wiedergegebenen Aggregaten. Zu den in Figur 1 dargestellten Leitungen 14 gehören eine Verriegelungsleitung V, eine Entriegelungsleitung E und eine gemeinsame Rückleitung R. Die Mehrfach-Schalter 13 bestehen jeweils aus einem Verriegelungsschalter II und einem Entriegelungsschalter I.In the circuit diagram of Figure 2, several units 1 to n are shown. Each unit represents a braking element 5 with the units shown in FIG. 1. The lines 14 shown in FIG. 1 include a locking line V, an unlocking line E and a common return line R. The multiple switches 13 each consist of a locking switch II and an unlocking switch I.

Im einzelnen ist die Anordnung derart, daß jedem Stellelement 9 ein davon betätigbarer, in der Verriegelungsleitung V angeordneter Verriegelungsschalter II zugeordnet ist und außerdem ein vom Stellelement 9 betätigbarer, in der Entriegelungsleitung E angeordneter Entriegelungsschalter I zugeordnet ist. Die Verriegelungsschalter II sind in Entriegelungsstellung an die Rückleitung R angeschlossen und in den dadurch gebildeten Stromkreisen liegen die Spulen S der Permanentmagneten 11. Entsprechendes gilt für die Entriegelungsschalter I, jedoch mit der Maßgabe, daß diese im Verriegelungszustand an die gemeinsame Rückleitung R angeschlossen sind.In detail, the arrangement is such that each actuating element 9 is assigned a lock switch II which can be actuated and is arranged in the locking line V, and in addition an unlocking switch I which is actuated by the actuating element 9 and is arranged in the unlocking line E is assigned. The locking switches II are connected to the return line R in the unlocked position and the coils S of the permanent magnets 11 are in the circuits thus formed. The same applies to the unlocking switch I, but with the proviso that they are connected to the common return line R in the locked state.

Hinsichtlich der Spulen S sind zwei mögliche Anordnungen wiedergegeben. Im Bereich der Einheit 1 ist sowohl in dem mit der Verriegelungsleitung V als auch in dem mit der Entriegelungsleitung E gebildeten Stromkreis eine Spule S angeordnet. Bei der im Bereich der Einheit 2 wiedergegebenen Schaltung ist lediglich eine Spule S in dem mit der Verriegelungsleitung V gebildeten Stromkreis wiedergegeben, der allerdings eine Diode D1 vorgeschaltet ist, wobei zwischen der Diode D1 und der Spule eine Zweigleitung abgeht, die eine weitere Diode D2 enthält und die zum entsprechenden Schaltkontakt des Entriegelungsschalters I führt.With regard to the coils S, two possible arrangements are shown. A coil S is arranged in the area of the unit 1 both in the circuit formed with the locking line V and in the circuit formed with the unlocking line E. In the circuit shown in the area of the unit 2, only one coil S is shown in the circuit formed with the locking line V, which, however, is preceded by a diode D1, a branch line going off between the diode D1 and the coil and containing a further diode D2 and which leads to the corresponding switch contact of the unlocking switch I.

Die dargestellte Gleisbremsanlage arbeitet wie folgt:The track braking system shown works as follows:

Solange die Bremselemente 5 sich in ihrer gestrichelt dargestellten, oberen, aktiven Bremsstellung befinden, werden sie vom Spurkranz 3 jedes Rades niedergedrückt und üben dementsprechend eine Bremswirkung auf jedes Rad aus. Die Verriegelungselemente 8 befinden sich in der gestrichelt dargestellten, inaktiven Stellung. Sie werden dort durch die an den Stellelementen 9 wirkenden Remanenzkräfte der Permamentmagneten 11 gehalten.As long as the braking elements 5 are in their broken, upper, active braking position, they are depressed by the wheel flange 3 of each wheel and accordingly exert a braking effect on each wheel. The locking elements 8 are in the inactive position shown in dashed lines. They are held there by the remanence forces of the permanent magnets 11 acting on the adjusting elements 9.

Soll die Bremswirkung einer Gruppe von n Einheiten aufgehoben werden, dann wird Spannung an die Verriegelungsleitung V gelegt. Dabei wird der Stromkreis des Verriegelungsschalters II der Einheit 1 über die zugeordnete Spule S und die Rückleitung R geschlossen. Die Magnetkraft der Spule S überwindet die Remanenzkraft, so daß das Verriegelungselement 8 in die aktive, mit durchgezogenen Linien wiedergegebene Stellung ausgeschwenkt wird. Dabei wird auch der Schalter nach dem sogenannten Kipp-Punkt gelegt, so daß er die Verriegelungsleitung V mit dem entsprechenden Abschnitt der nächsten Einheit 2 verbindet, und so weiter fort, bis auch das letzte Verriegelungselement 8 der Einheit N ausgeschwenkt ist. Dann erfolgt eine Meldung, daß alle Verriegelungselemente 8 ausgeschwenkt sind. Das erste Rad eines Wagens oder einer Wagengruppe, die die Einheit 1 überfährt, drückt das Bremselement 5 nieder, wobei es das Verriegelungselement 8 beiseite drückt, welches jedoch unter der Wirkung der Druckfeder 10 wieder in die ausgeschwenkte Stellung zurückkehrt, nachdem der Kopf des Bremselementes 5 das Verriegelungselement 8 passiert hat. Danach wird das Bremselement 5 vom Verriegelungselement 8 in niedergedrückter Stellung gehalten. Die Konstruktion ist so eingerichtet, daß die auf das Bremselement 5 und damit das Verriegelungselement 8 wirkende Kolbenkraft das Verriegelungselement 8 in ausgeschwenkter Stellung hält. Die nächsten Räder des Wagens oder der Wagengruppe werden dann nicht mehr gebremst.If the braking effect of a group of n units is to be canceled, then voltage is applied to the locking line V. The circuit of the locking switch II of the unit 1 is closed via the associated coil S and the return line R. The magnetic force of the coil S overcomes the remanence force, so that the locking element 8 is pivoted out into the active position shown by solid lines. The switch is also placed after the so-called toggle point, so that it connects the locking line V to the corresponding section of the next unit 2, and so on, until the last locking element 8 of the unit N is swung out. Then there is a message that all locking elements 8 are pivoted out. The first wheel of a wagon or group of wagons that passes over the unit 1 depresses the braking element 5, pushing the locking element 8 aside, which, however, returns to the pivoted-out position under the action of the compression spring 10 after the head of the braking element 5 has passed the locking element 8. Thereafter, the braking element 5 is held by the locking element 8 in the depressed position. The construction is designed so that the piston force acting on the braking element 5 and thus the locking element 8 holds the locking element 8 in the pivoted-out position. The next wheels of the car or group of cars are then no longer braked.

Sollen die Bremselemente 5 wieder in ihre aktive Bremsstellung zurückgebracht werden, wird Spannung an die Entriegelungsleitung E gelegt Hier laufen die Vorgänge wie oben beschrieben ab, so daß alle Verriegelungelemente 8 nacheinander in ihre inaktive Stellung innerhalb des Gehäuses 6 zurückgeschwenkt werden. Im unteren Teil der Figur 2 ist der Endzustand wiedergegeben. Auch in diesem Fall erfolgt eine Vollzugsmeldung.If the braking elements 5 are to be brought back into their active braking position, voltage is applied to the unlocking line E Here the operations proceed as described above, so that all locking elements 8 are successively pivoted back into their inactive position within the housing 6. The final state is shown in the lower part of FIG. In this case, too, there is a notification of execution.

Sollte im einen oder anderen Fall das Bremselement 5 zum Beispiel durch Erschütterungen oder dergleichen seine vorbestimmte Stellung verlassen, dann wird dabei auch das Verriegelungselement 8 verschwenkt und über den Schalthebel 12 der Schalter 13 betätigt, womit die Kaskade an beliebiger Stelle wieder wirksam wird und das Bremselement 5 oder weitere Bremselemente in die gewünschte Stellung bringtIf, in one case or another, the braking element 5 leaves its predetermined position, for example due to vibrations or the like, then the locking element 8 is also pivoted and the switch 13 is actuated via the switching lever 12, as a result of which the cascade becomes active again at any point and the braking element Brings 5 or more brake elements into the desired position

Während bei Gleisbremsanlagen nach dem eingangs erläuterten Stand der Technik eine Energiemenge von etwa 400 J erforderlich ist, um ein Bremselement 5 aus der aktiven Bremsstellung in die inaktive Grundstellung zu überführen, genügt bei der erfindungsgemäßen Ausführung eine Energiemenge von 0,5 mJ.While an amount of energy of approximately 400 J is required to switch a brake element 5 from the active braking position to the inactive basic position in the case of track braking systems according to the prior art explained at the outset, an amount of energy of 0.5 mJ is sufficient in the embodiment according to the invention.
