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.

Die weiteren Merkmale, Einzelheiten und Vorteile der Erfindung ergeben sich aufgrund der nachfolgenden Beschreibung sowie anhand der Zeichnung. Diese zeigt in

Fig. 1
eine vereinfachte perspektivische Darstellung eines Kranschienenprofiles im Austrittsbereich eines Extrusionswerkzeuges sowie in den
Fig. 2 bis 4
unterschiedliche Gestaltungen von Leiterbah nen in bzw. an einem solchen Profil.
The further features, details and advantages of the invention result from the following description and from the drawing. This shows in
Fig. 1
a simplified perspective view of a crane rail profile in the exit area of an extrusion tool and in the
2 to 4
different designs of tracks in or on such a profile.

Aus einem nur gestrichelt dargestellten Extruderkopf 1 tritt eine Kunststoffkranschiene 2 als nach unten offenes Kastenprofil aus, wobei Stege 3 als Laufschienen für nicht näher dargestellte Kranrollen gebildet sind.From an extruder head 1, shown only in broken lines occurs a plastic crane rail 2 as open at the bottom Box profile, with webs 3 as rails for Crane roles not shown are formed.

Im vorliegenden Beispiel weist die Kranschiene, ohne darauf beschränkt zu sein, vier innere Stromschienen auf, wobei diese Stromschienen als Kupferleiterbahnen 4' im Inneren des Extruders vor dem Extrusionskopf 1 in die Extrusionsanlage eingeführt und zusammen mit dem Kranschienenprofil extrudiert werden, was durch die Pfeile 5 in Fig. 1 angedeutet ist.In the present example, the crane rail points without pointing to it to be limited to four inner tracks, these busbars as copper conductor tracks 4 'in Inside the extruder in front of the extrusion head 1 in the extrusion system introduced and together with the crane rail profile are extruded, which is indicated by the arrows 5 in Fig. 1 is indicated.

Sind die Stromschienen bzw. Leiterbahnen aus elektrisch leitendem Kunststoff gefertigt, sind etwas einfachere Gestaltungen des Innenraumes der Kranschiene 2 möglich, einige derartiger Gestaltungen sind in Fig. 2 bis 4 dargestellt.Are the conductor rails or conductor tracks made of electrical? made of conductive plastic, are somewhat simpler designs the interior of the crane rail 2 possible, some such designs are shown in Figs. 2-4 shown.

Fig. 2 zeigt die Möglichkeit einer coextrudierten Stromschiene 4a aus Kunststoff, die so mit dem Profil 2a extrudiert wurde, daß sie bereichsweise in die mit 6 bezeichnete Profilwand eintaucht und bereichsweise über die Innenfläche dieser Wand hervorsteht.Fig. 2 shows the possibility of a coextruded busbar 4a made of plastic, so extruded with the profile 2a was that in some areas it was labeled 6 Immersed profile wall and in some areas over the The inner surface of this wall protrudes.

In Figur 3 sind die Kunststoffleiterbahnen 4b auf die Innenfläche der Profilwand 6 aufgebracht, während in Fig. 4 die Leiterbahnen 4c einen direkten Teil der Wand 6 des Profiles 2c bilden.In Figure 3, the plastic traces 4b are on the inner surface the profile wall 6 applied, while in Fig. 4th the conductor tracks 4c a direct part of the wall 6 of the Form profiles 2c.

Wie in Figur 1 angedeutet, kann, wie an sich bekannt, an der Außenfläche des Kunststoffprofiles eine farbige Kennzeichnung 7 angebracht sein, um gegebenenfalls einen der Leiter zu identifizieren bzw. das Einsetzen des Kranlaufwerkes in die Schiene so vornehmen zu können, daß beispielsweise der Nulleiter richtig getroffen wird, hierzu kann auch das Austrittsprofil der Schiene selbst beitragen, etwa wenn ein Schenkel 8 länger ausgebildet ist als der gegenüberliegende Schenkel 9, was für sich gesehen bekannt ist.As indicated in FIG. 1, as is known per se, can a colored marking on the outer surface of the plastic profile 7 may be appropriate to one of the Identify the ladder or insert the crane drive to be able to make in the rail so that, for example the neutral conductor is hit correctly, for this can also contribute to the emergence profile of the rail itself, about if a leg 8 is longer than the opposite leg 9 what seen in isolation is known.

Natürlich sind die beschriebenen Ausführungsbeispiele der Erfindung noch in vielfacher Hinsicht abzuändern, ohne den Grundgedanken zu verlassen. So können bei extrudierten elektrisch leitenden Kunststoffstromschienen 4a bis 4c diese selbst ebenfalls querschnittlich profiliert sein, um sich den darauf gleitenden Stromabnehmern gegebenenfalls besser anpassen zu können, die Kunststoffleiterbahnen können unterschiedlich gefärbt sein und dgl. mehr.Of course, the described embodiments of the Change invention in many ways without to leave the basic idea. So with extruded electrically conductive plastic busbars 4a to 4c this itself also profiled in cross section be to the pantographs sliding on it if necessary to be able to better adapt the plastic conductor tracks can be colored differently and the like. more.
