Description
Die Erfindung bezieht sich auf einen Heizstab für Straßenfertiger mit einer elektrischen Heizeinrichtung der im Oberbegriff von Anspruch 2 erläuterten Art.The invention relates to a heating element for paver with an electric heater explained in the preamble of
Ein derartiger Straßenfertiger ist aus der
Straßenfertiger sind mit einer Heizeinrichtung versehen, die die unterschiedlichsten Arbeitskomponenten beheizen, die mit dem erhitzten Einbaumaterial zum Herstellen von Fahrbahndecken in Berührung kommen, um einerseits ein verfrühtes Abkühlen des Einbaumaterials zu verhindern und um andererseits zu verhindern, dass Einbaumaterial an kalten Flächen der jeweiligen Arbeitskomponente erstarrt und haften bleibt. Diese Heizeinrichtungen enthalten normalerweise Heizstäbe, die direkt an der zu beheizenden Komponente angeordnet werden müssen. Naturgemäß sind nicht alle derjenigen Stellen, an denen ein Heizstab montiert werden muss, von außen leicht zugänglich. Oft ist eine komplette Abschaltung des Straßenfertigers und eine Auskühlung über Nacht erforderlich, bevor ein Heizstab zugänglich ist. Dies erschwert den Austausch und die Montage defekter Heizstäbe beträchtlich.Pavers are provided with a heating device that heats the various working components that come into contact with the heated paving material for making pavements, on the one hand to prevent premature cooling of the paving material and, on the other hand, to prevent paving material from solidifying on cold surfaces of the respective working component and sticks. These heaters usually contain heating elements that must be placed directly on the component to be heated. Of course, not all those places where a heating element must be mounted, easily accessible from the outside. Often a complete shutdown of the paver and a cooling overnight is required before a heating element is accessible. This considerably complicates the replacement and assembly of defective heating elements.
Der Erfindung liegt somit die Aufgabe zugrunde, einen Heizstab für Straßenfertiger mit einer elektrischen Heizeinrichtung bereitzustellen, bei der Defekte in der Heizeinrichtung besser kompensiert werden können.The invention is therefore based on the object to provide a heater for paver with an electric heater, can be compensated for the defects in the heater better.
Die Aufgabe wird durch die im Anspruch 1 angegebenen Merkmale gelöst.The object is solved by the features specified in claim 1.
Durch die erfindungsgemäße Ausgestaltung wird der Reparaturort im Falle eines Defekts an der Heizeinrichtung an eine Stelle verlagert, die vom Benutzer zugänglich ist, so dass ohne Abschalten des Straßenfertigers, gegebenenfalls im laufenden Betrieb, die Heizeinrichtung durch einfaches Umklemmen oder Umschalten repariert werden kann.The inventive design of the repair location is relocated in the event of a defect in the heater to a location that is accessible to the user, so that without switching off the paver, possibly during operation, the heater can be repaired by simply reconnecting or switching.
Vorteilhafte Weiterbildungen des Straßenfertigers sind dem Unteranspruch 3 zu entnehmen.Advantageous developments of the paver can be found in the
Ein Ausführungsbeispiel des erfindungsgemäßen Heizstabes wird nachfolgend anhand der Zeichnung 1 näher erläutert. Es zeigen:
- Fig. 1
- ein Ausführungsbeispiel eines erfindungsgemäßen Heizstabes zur Verwendung in einem Straßenfertiger, und
- Fig. 2
- eine schematische Darstellung eines Heizstabes, der nicht Teil der Erfindung ist zur Verwendung in einem Straßenfertiger.
- Fig. 1
- an embodiment of a heating element according to the invention for use in a paver, and
- Fig. 2
- a schematic representation of a heating rod, which is not part of the invention for use in a paver.
Im normalen Betrieb wird nur eine der Heizwendeln 3 oder 4 mit Strom versorgt und liefert die volle für die Heizeinrichtung notwendige Heizleistung. Die andere Heizwendel ist von der Stromversorgung getrennt, also beispielsweise durch einen entsprechend gestellten Schalter oder durch Abklemmen. Fällt nun die in Betrieb befindliche Heizwendel aus, so ist es lediglich notwendig, entweder die Zuleitungen umzuklemmen, oder den entsprechenden Schalter zu betätigen, damit die andere Heizwendel in Betrieb gesetzt wird und wiederum die volle Heizleistung bringt.In normal operation, only one of the
Abweichend von der Darstellung in
Bei diesem Heizstab ist es, wie
In Abwandlung der beschriebenen Heizstäbe kann die Anzahl der Heizwendeln erhöht werden. Statt Flachheizkörper kann die Erfindung auch bei anderen Heizeinrichtungen eingesetzt werden.In a modification of the heating elements described, the number of heating coils can be increased. Instead flat radiator, the invention can also be used in other heaters.
Claims (3)
- A heating rod (1) which has a predetermined nominal heating power corresponding to the full heating power and which is used for a heating unit of a road finisher for heating work components, comprising a plurality of heating spirals (3, 4) each having an electric lead (6, 7) of its own, characterized in that the heating power of each of said heating spirals (3, 4) corresponds to the nominal heating power of the heating rod (1).
- A road finisher provided with an electric heating unit used for heating work components and comprising at least one heating rod (1) according to claim 1, characterized in that the leads (6, 7) of each heating spiral (3, 4) are alternately clamped to a distributor of a user-accessible connection means (8) or are alternately connected to a user-accessible connection means (8) via a switch.
- A road finisher according to claim 2, characterized in that the heating rod (1) comprises a heating element, in particular a flat heating element.
