Abstract
Description
Die Erfindung betrifft eine Kranschiene als bereichsweise nach unten offenes Kastenprofil oder C-Profil aus extrudiertem Kunststoff mit Laufschienen für die Kranrollen bildenden Stegen und inneren Stromschienen.The invention relates to a crane rail as a region box profile or C-profile made of extruded, open at the bottom Plastic with rails for the crane rollers webs and inner busbars.
Derartige Kranschienen sind in unterschiedlichen Gestaltungen bekannt ebenso als Stahlprofile als auch als Kunststoffprofile, wobei es insbesondere bei letzteren bekannt ist, diese Kunststoffprofile mit Aufnahmenuten im Inneren zu versehen, in die dann Kupferstäbe als Stromschienen eingeschoben werden. Durch das Einschieben der Kupferleiter sind die Längen derartiger Stromschienen begrenzt, so daß es zwangsläufig zu vergleichsweise vielen Schienenstößen kommt, wenn längere Kranbahnen verlegt werden. Zum Stand der Technik sei hier beispielsweise verwiesen auf: DE-U-80 24 772, DE-GM 69 08 221, WO-A-84 00 348 oder FR-A-25 67 819.Such crane rails are in different designs known as steel profiles as well as Plastic profiles, especially in the latter is known, these plastic profiles with grooves in the To provide inside, then copper bars as busbars be inserted. By inserting the Copper conductors, the lengths of such busbars are limited, so that inevitably there are comparatively many Rail joints occur when longer crane runs are laid become. The state of the art, for example referred to: DE-U-80 24 772, DE-GM 69 08 221, WO-A-84 00 348 or FR-A-25 67 819.
Aufgabe der Erfindung ist die Schaffung einer Lösung, mit der wenigstens theoretisch eine Endlosherstellung derartiger Kranschienen aus Kunststoff möglich ist.The object of the invention is to provide a solution with at least theoretically an endless production of such Crane rails made of plastic is possible.
Bei einer Kranschiene der eingangs bezeichneten Art wird diese Aufgabe gemäß der Erfindung dadurch gelöst, daß die Stromschienen als coextrudierte Leiterbahnen ausgebildet sind. In the case of a crane rail of the type mentioned at the beginning solved this problem according to the invention in that the Busbars designed as co-extruded conductor tracks are.
Dadurch, daß die Leiterbahnen bei der Herstellung des Kunststoffkranschienenprofiles gleichzeitig mitextrudiert werden, ist es möglich, diese Kranschienen in großen Längen herzustellen.The fact that the conductor tracks in the manufacture of Plastic crane rail profile extruded at the same time it is possible to use these crane rails in great lengths to manufacture.
Dabei ist es möglich, in den Extruderkopf für die Kunststoffkranschienen die Stromschienen als Kupfermetallbänder mit einzuspeisen und dem Vorschub der Extrusionen der Kranschiene anzupassen.It is possible in the extruder head for the plastic crane rails the busbars as copper metal strips with feed and the feed of the extrusions of the Adjust crane rail.
Eine spezielle Besonderheit der Erfindung besteht darin, die Stromschiene aus elektrisch leitendem Kunststoffmaterial auszubilden. Ein derart elektrisch leitendes Kunststoffmaterial macht es möglich, bei der Extrusion der Kranschiene dieses gleichzeitig an den gewünschten Stellen mit zu extrudieren.A special feature of the invention is the busbar made of electrically conductive plastic material to train. Such an electrically conductive plastic material makes it possible when extruding the Crane rail this at the desired places at the same time to extrude with.
Je nach Einsatzart der Schiene kann es auch möglich sein, Wandbereiche der Kranschiene aus elektrisch leitendem Material unter Zwischenlage von isolierendem Kunststoff auszubilden, wobei eine besondere Möglichkeit durch die Art der Herstellung darin besteht, daß zur Kenntlichmachung unterschiedlicher Leiter das elektrisch leitende Kunststoffmaterial farblich unterschiedlich ausgestaltet wird, etwa in den für Leiter üblichen nach der DIN-Norm vorgeschriebenen Farben. Depending on the type of use of the rail, it may also be possible Wall areas of the crane rail made of electrically conductive material with the interposition of insulating plastic train, with a special possibility through the Type of manufacture is that of identification different conductors the electrically conductive Plastic material in different colors is, for example in the usual for conductors according to the DIN standard prescribed colors.
