Abstract

A current contact line arrangement includes a plurality of energy and control current contact lines for engagement with current collectors of a movable energy consumer such as a crane, trolley carriage or the like which is not intended to pass beyond a predetermined point and is characterized by the fact that at least one of the energy or control current contact lines (5) is covered by an insulator (9) which is longer than the brake path of the movable energy consumer.

Description

Die Erfindung betrifft eine Schleifleitungsanordnung mit Energie- und Steuer-Schleifleitungen für Stromabnehmer eines auf Fahrschienen verfahrbaren Energieverbrauchers, der vorbestimmte Stellen bzw. Schienenabschnitte nicht überfahren darf. Eine solche Anordnung ist aus dem Dokument FR-A-2 583 901 bereits bekannt.The invention relates to a conductor line arrangement with energy and control conductor lines for pantographs of an energy consumer which can be moved on rails and which must not drive over predetermined locations or rail sections. Such an arrangement is already known from document FR-A-2 583 901.

Bisher sind bei Kranen, Katzen oder dgl. Endschalter angeordnet, die nicht überfahren werden, damit das Anfahrmaß eingehalten wird. Derartige Endschalter müssen durch zusätzliche Leitungen mit der Steuerelektrik verbunden werden und sind daher zum Verhindern des Überfahrens einer bestimmten Stelle unnötig teuer.So far, limit switches have been arranged on cranes, cats or the like, which are not run over so that the approach dimension is maintained. Such limit switches have to be connected to the control electronics by means of additional lines and are therefore unnecessarily expensive in order to prevent them from crossing a certain point.

Aufgabe der Erfindung ist es daher, eine gegenüber einem Endschalter weniger aufwendige Anordnung zum Verhindern des Überfahrens einer vorbestimmten Stelle zu schaffen.It is therefore an object of the invention to provide a less complicated arrangement for preventing a predetermined position from being passed over than a limit switch.

Diese Aufgabe wird durch die im kennzeichnenden Teil des Patentanspruchs 1 angegebenen Merkmalen gelöst.This object is achieved by the features specified in the characterizing part of patent claim 1.

Ein derartiges Isolierstück ist je nach dem Anhalteweg des Krans, der Katze oder dgl. 0,2 bis 0,4 m lang und ist weniger aufwendig als der bisherige Endschalter.Depending on the stopping distance of the crane, the cat or the like, such an insulating piece is 0.2 to 0.4 m long and is less expensive than the previous limit switch.

Das Isolierstück ist vorzugsweise nur auf der Signal-Schleifleitung angeordnet und bewirkt das Abfallen der Schütze und der verfahrbare Energieverbraucher bleibt stehen.The insulating piece is preferably arranged only on the signal conductor line and causes the contactors to drop out and the movable energy consumer stops.

In weiterer Ausgestaltung der Erfindung ist das Isolierstück aus einem Kunststoff mit einem elektrischen Oberflächenwiderstand von mindestens 10¹⁰ Ohm hergestellt und hat die Form eines U- oder T-Profiles, das zum Erhöhen des Kriechstromschutzes gewellt oder mit Rippen versehen ist.In a further embodiment of the invention, the insulating piece is made of a plastic with an electrical surface resistance of at least 10¹⁰ ohms and has the shape of a U or T profile, which is corrugated or provided with ribs to increase the leakage current protection.

Das Material des Isolierstücks kann so auf die Eigenschaften der Stromabnehmerkohle abgestimmt werden, daß sich eine gute Gleitpaarung ergibt und der Verschleiß am Isolierstück vernachlässigt werden kann. Es kann mit Schnappnasen in Hinterschneidungen von Schleifleitungsnuten eines Schleifleitungsträgers eingreifen oder, wenn die Schleifleitung ein U- oder C-förmiges Profil ist, an dem die Stromabnehmer von außen entlanggleiten, kann das Isolierstück ein die Schleifleitung klemmend umfassendes C-Form-Profil sein. Zum guten Abheben des Stromabnehmers von den Schleifleitungen hat das Isolierstück abgeschrägte Enden, wobei die Abschrägung ca. 30 Grad beträgt.The material of the insulating piece can be matched to the properties of the current collector carbon in such a way that a good sliding pairing results and the wear on the insulating piece can be neglected. It can engage with undercuts in the undercuts of conductor rail grooves in a conductor rail carrier or, if the conductor rail is a U-shaped or C-shaped profile along which the pantographs slide from the outside, the insulating piece can be a C-shaped profile that encompasses the conductor rail. The insulating piece has bevelled ends for good lifting of the pantograph from the conductor lines, the beveling being approximately 30 degrees.

Falls die Gefahr besteht, daß das Isolierstuck auf der Schleifleitung verschoben werden kann, kann es durch eine Verklebung gesichert sein, bei die Verklebung mit einem Klebeband erreicht wird, das mit der Seite der größeren Klebekraft zunächst an das Isolierstück geklebt wird und dann auf der Schleifleitung gesichert wird. Wenn dann das Isolierstück wieder entfernt oder an einer anderen Stelle angebracht werden muß, löst man beim Abnehmen des Isolierstückes auch gleichzeitig die Verklebung von der Schleifleitung.If there is a risk that the insulating piece can be moved on the conductor rail, it can be secured by gluing, which is achieved with an adhesive tape that is first glued to the insulating element with the side of the greater adhesive force and then on the conductor rail is secured. If the insulating piece then has to be removed again or attached at another location, the adhesive is also detached from the conductor rail when the insulating piece is removed.

An einem Kranträger 1 ist eine Katze 3 verfahrbar, deren Stromabnehmer 4 zur Versorgung des Hubwerkmotors und Fahrwerkmotors mit Strom und Steuersignaien an Schleifleitungen 5 entlanggleiten. Damit das Anfahrmaß X der Katze 3 an den Kopfträger 2 nicht unterschritten wird, ist an der Signal-Schleifleitung für den Fahrmotor für Fahrtrichtung 5 "links" ein Isolierstück 9 über der Schleifleitung 5 angeordnet, wie in den Fig. 5 und 6 sowie 7 und 8 dargestellt. Die Länge Y des Isolierstückes 9 ist größer als der Anhalteweg der Katze 3. Da nur das Signal für die Fahrtrichtung links unterbrochen wird, ist es weiterhin möglich, mit dem Signal Fahrtrichtung "rechts" die Katze wieder aus dem Endbereich hinauszufahren. Bei Katzen mit einer zusätzlichen schnellen Fahrgeschwindigkeit werden Isolierstücke der Länge Z, die das Signal für die Schnellfahrt unterbrechen, vor den Bereich Y gesetzt. Dadurch kann im Bereich Z noch mit langsamer Fahrgeschwindigkeit gefahren werden und der Bereich Y kann so kurz gewählt werden, wie für das Anhalten aus der Langsamfahrt erforderlich.A trolley 3 can be moved on a crane girder 1, its pantographs 4 sliding along conductor lines 5 to supply the hoist motor and chassis motor with power and control signals. So that the approach dimension X of the trolley 3 to the head carrier 2 is not undershot, an isolating piece 9 is arranged on the signal conductor line for the drive motor for the direction of travel 5 "left" above the conductor line 5, as in FIGS. 5 and 6 and 7 and 8 shown. The length Y of the insulating piece 9 is greater than the stopping distance of the cat 3. Since only the signal for the direction of travel to the left is interrupted, it is still possible to drive the cat out of the end area again with the signal to the direction of travel "right". In cats with an additional fast driving speed, insulating pieces of length Z, which interrupt the signal for fast driving, are placed in front of area Y. As a result, the area Z can still be driven at a slow speed and the area Y can be selected to be as short as is necessary for stopping from the slow travel.

Als zusätzliche Sicherheitsmaßnahme ist es möglich, durch Anordnung von Isolierstücken auf den Energie-Schleifleitungen im Bereich X die Stromversorgung des Fahrmotors zu unterbrechen, falls der Bereich Y als Folge eines Fehlers überfahren wurde. Die hier für das linke Katzbahnende beschriebenen Maßnahmen sind entsprechend für das rechte Katzbahnende zu wiederholen.As an additional safety measure, it is possible to interrupt the power supply to the traction motor by arranging insulating pieces on the energy conductor lines in area X if area Y has been overrun as a result of a fault. The measures described here for the left end of the trolley track must be repeated for the right end of the trolley track.

Das Isolierstück 9 ist nach Fig. 2 ein U-Profil und hat an den Enden Abschrägungen 12, die ein Anstoßen des Stromabnehmers 4 bei Überfahren des Isolierstückes 9 verhindern. Es ist mit Schnappnasen 13 an Hinterschneidungen 8 in Nuten 7 eines Schleifleitungsträgers 6 eingesetzt und durch eine Verklebung gegen Verschieben gesichert. In die Schleifleitungsnut 7 kann auch ein T-förmiges Isolierstück nach Fig. 4 eingesetzt sein, dessen Steg 9c mit Rippen 11 versehen ist. Die Auflagefläche 10 des Isolierstückes 9 rastet mit den Seiten des Flansches 9b in die Hinterschneidungen 8 des Schleifleitungsträgers 6 ein.The insulating piece 9 is a U-profile according to FIG. 2 and has bevels 12 at the ends which prevent the pantograph 4 from bumping when the insulating piece 9 is passed over. It is inserted with snap lugs 13 on undercuts 8 in grooves 7 of a conductor rail support 6 and secured against displacement by an adhesive. A T-shaped insulating piece according to FIG. 4, the web 9c of which is provided with ribs 11, can also be inserted into the conductor line groove 7. The contact surface 10 of the insulating piece 9 engages with the sides of the flange 9b in the undercuts 8 of the conductor rail carrier 6.

Die Schleifleitung 5 A ist nach den Fig. 7 und 8 ein C-Profil, das von dem entsprechend geformten isolierstück 9 A klemmend umfaßt wird. In allen Fällen haben die Enden der Isolierstücke an den Enden Abschrägungen 12 in einem Winkel von etwa 30 Grad zur Fahrtrichtung des Stromabnehmers.The conductor rail 5 A is according to FIGS. 7 and 8 a C-profile, which is clamped by the correspondingly shaped insulating piece 9 A. In all cases, the ends of the insulating pieces have bevels 12 at the ends at an angle of approximately 30 degrees to the direction of travel of the pantograph.
