Description

Die Erfindung betrifft eine Laufkatze mit mindestens einem Laufrad und diesem zugeordneten Führungsrollen, die an übereinanderliegenden, vorzugsweise senkrechten Führungsflächen eines Schienenträgers anliegen.The invention relates to a trolley with at least one running wheel and guide rollers associated therewith, which rest on superimposed, preferably vertical guide surfaces of a rail support.

Eine Laufkatze dieser Art ist durch die DE-AS 23 53 622 bekannt und hat für jedes Laufrad bzw. Laufradpaar acht Führungsrollen, die die Laufkatze im geraden und gekrümmten Schienenbereich einwandfrei an den Führungsflächen des Schienenträgers führen. Bei einer Laufkatze mit als Diabolorolle ausgebildetem Laufrad nach der DE-AS 18 08 210 ersetzt die Diabolorolle obere Führungsrollen, so daß an einem Fahrwerk nur vier untere Führungsrollen erforderlich sind. Bei einem stark gekrümmten Schienenträger kommt es zu Zwängungen zwischen dem Rand der Diabolorolle und den oberen Führungsflächen des Schienenträgers einerseits und den unteren Führungsflächen des Schienenträgers mit den unteren Führungsrollen andererseits. Diese Zwängungen lassen sich nur durch einen großen Abstand zwischen den Führungsflächen und den Führungsrollen vermeiden, die dann aber die Laufkatze auf einer geraden Strecke nicht mehr ausreichend führen. Eine ungenaue Führung bedeutet, daß die Stromabnehmer aufwendig sind und daß für die Steuerung der Laufkatze nur Schaltgeräte eingesetzt werden können, die einen sehr großen Schaltabstand zulassen und deshalb sehr teuer sind.A trolley of this type is known from DE-AS 23 53 622 and has eight guide rollers for each wheel or pair of wheels, which guide the trolley perfectly in the straight and curved rail area on the guide surfaces of the rail support. In a trolley with a wheel designed as a diabolo roller according to DE-AS 18 08 210, the diabolo roller replaces upper guide rollers, so that only four lower guide rollers are required on a trolley. In the case of a strongly curved rail support, there are constraints between the edge of the diabolo roller and the upper guide surfaces of the rail support on the one hand and the lower guide surfaces of the rail support with the lower guide rollers on the other hand. These constraints can only be avoided by a large distance between the guide surfaces and the guide rollers, which then no longer adequately guide the trolley on a straight track. Inaccurate guidance means that the pantographs are complex and that only switching devices can be used to control the trolley that allow a very large switching distance and are therefore very expensive.

Aufgabe der Erfindung ist es daher, eine Laufkatze so zu gestalten, daß mit geringem Aufwand eine einwandfreie Führung der Laufkatze am Schienenträger ermöglicht ist. Diese Aufgabe wird dadurch gelöst, daß an der Laufkatze für die oberen und unteren Führungsflächen jeweils zwei sich diagonal gegenüberliegende Führungsrollen gelagert sind, wobei sich gedachte Verbindungslinien zwischen allen Führungsrollen kreuzen. Es sind trotz einwandfreier oberer und unterer Führung nur insgesamt vier Führungsrollen erforderlich, nämlich auf jeder Seite eine obere und eine untere, wobei eine am vorderen und die andere am hinteren Ende der Laufkatze angeordnet ist. Es liegen sich keine Führungsrollen direkt gegenüber. Die oberen Führungsrollen verhindern zusammen mit den unteren ein Kippen der Laufkatze am Schienenträger und die vorderen Führungsrollen gewährleisten zusammen mit den hinteren die einwandfreie Führung der Laufkatze in Längsrichtung des Schienenträgers. Somit wurde trotz einwandfreier Führung die Hälfte der sonst üblichen Führungsrollen eingespart. Zwischen den Führungsflächen und den Führungsrollen kann ein kleiner Zwischenraum von etwa 1 mm zum Ausgleichen von Toleranzen am Abstand der Führungsflächen des Schienenträgers voneinander vorhanden sein. Dieser Zwischenraum kann bei Anlagen mit großen Radien etwas kleiner und bei Anlagen mit sehr engen Radien etwas größer gehalten sein.The object of the invention is therefore to design a trolley so that the trolley can be guided correctly on the rail support with little effort. This object is achieved in that two diagonally opposite guide rollers are mounted on the trolley for the upper and lower guide surfaces, with imaginary connecting lines crossing between all guide rollers. Despite proper upper and lower guidance, only a total of four guide rollers are required, namely an upper and a lower one on each side, one at the front and the other at the rear end of the trolley. There are no leadership roles directly opposite. The upper guide rollers, together with the lower ones, prevent the trolley from tipping on the rail support, and the front guide rollers, together with the rear ones, ensure that the trolley is guided properly in the longitudinal direction of the rail support. Thus, despite flawless leadership, half of the usual leadership roles were saved. Can between the guide surfaces and the guide rollers there should be a small space of about 1 mm to compensate for tolerances on the distance between the guide surfaces of the rail support. This space can be kept somewhat smaller in systems with large radii and somewhat larger in systems with very narrow radii.

In einer weiteren Ausgestaltung der Erfindung können jeweils die oberen und unteren Führungsrollen mit ihren Achsen in Lagerbohrungen von Längsträgern gelagert sein. Der obere und der untere Längsträger sind dann über einen senkrechten Stegträger miteinander verbunden, der als Drehstabfeder ausgebildet sein kann.In a further embodiment of the invention, the upper and lower guide rollers can each be mounted with their axes in the bearing bores of longitudinal members. The upper and the lower longitudinal beams are then connected to one another via a vertical web beam, which can be designed as a torsion bar spring.

In einer anderen Ausgestaltung der Erfindung sind die oberen Führungsrollen über einen Längsträger miteinander verbunden, der an den den Führungsrollen gegenüberliegenden längsseitigen Enden senkrechte Stegträger für die unteren Führungsrollen hat, wobei die Stegträger als Blattfedern ausgebildet sein können. Bei Ausbildung der Stegträger als Drehstabfeder oder Blattfeder muß der erwähnte Zwischenraum zwischen den Führungsflächen und den Führungsrollen nicht vorhanden sein, da nötigenfalls der federnde Stegträger ein Nachgeben der Führungsrollen zuläßt. Die Achsen der Führungsrollen können auch unter dem Druck von Federn in Richtung auf die Führungsflächen in den Längsträgern verschiebbar gelagert sein. Bei allen denkbaren Bauformen der Laufkatze werden vier der sonst üblichen acht Führungsrollen ohne Beeinträchtigung des Fahrverhaltens eingespart.In another embodiment of the invention, the upper guide rollers are connected to one another via a longitudinal support which has vertical web supports for the lower guide rollers at the longitudinal ends opposite the guide rollers, wherein the web supports can be designed as leaf springs. When the web carrier is designed as a torsion bar spring or leaf spring, the space mentioned between the guide surfaces and the guide rollers does not have to be present, since the resilient web carrier allows the guide rollers to yield if necessary. The axes of the guide rollers can also be displaceably supported in the longitudinal beams under the pressure of springs in the direction of the guide surfaces. In all conceivable designs of the trolley, four of the otherwise usual eight guide rollers are saved without impairing driving behavior.

Zum Transportieren größerer Lasten können in Fahrtrichtung hintereinander angeordnete Laufkatzen über einen Lastenträger gelenkig miteinander verbunden sein.To transport larger loads, trolleys arranged one behind the other in the direction of travel can be articulated to one another via a load carrier.

Drei Ausführungsbeispiele der Erfindung sind in der Zeichnung dargestellt und im folgenden erläutert. Es zeigen:

  • Fig. 1 eine am Schienenträger angeordnete Laufkatze in perspektivischer Darstellung,
  • Fig. 2 ein Teilstück eines Schienenträgers mit einer einfachen Laufkatze in der Seitenansicht,
  • Fig. 3 die Stirnansicht von Fig. 2, jedoch ohne Fahrmotor
  • Fig. 4 einen gekrümmten Schienenträger mii Führungsrollen in der Draufsicht.
  • Fig. 5 ein Teilstück eines Schienenträgers mit einer Doppel-Laufkatze in der Seitenansicht,
  • Fig. 6 eine Draufsicht auf Fig. 5.
  • Fig. 7 eine andere einrädrige Laufkatze.
Three embodiments of the invention are shown in the drawing and explained below. Show it:
  • 1 is a perspective view of a trolley arranged on the rail support,
  • 2 shows a section of a rail support with a simple trolley in a side view,
  • Fig. 3 is the front view of Fig. 2, but without the drive motor
  • Fig. 4 shows a curved rail support mii guide rollers in plan view.
  • 5 shows a section of a rail support with a double trolley in a side view,
  • 6 is a top view of FIG. 5.
  • 7 shows another single-wheeled trolley.

Bei beiden Ausführungsbeispielen fährt auf der Lauffläche la des Schienenträgers 1 eine Laufkatze 2 mit einem Tragrad 3. Dieses wird, mit Ausnahme der hinteren Laufkatze nach Fig. S von einem Fahrmotor 4 angetrieben. An oberen und unteren senkrechten Führungsflächen 1b des Schienenträgers 1 liegen mit geringem Zwischenraum Führungsrollen 5 der Laufkatze 2 an.In both exemplary embodiments, a trolley 2 with a carrying wheel 3 travels on the running surface la of the rail carrier 1. With the exception of the rear trolley according to FIG. S, this trolley is driven by a traction motor 4. Guide rollers 5 of the trolley 2 rest on the upper and lower vertical guide surfaces 1b of the rail support 1 with a small gap.

In Fig. 2 sind die Führungsrollen rechts oben und links unten gestrichelt und die Führungsrollen rechts unten und links oben mit Vollinien gezeichnet, d.h., die erstgenannten liegen hinter dem Schienenträger 1. Nur diese vier, die beiden sichtbaren und die beiden unsichtbaren Führungsrollen 5 gewährleisten die einwandfreie Führung der Laufkatze'2 am Schienenträger 1. In den Fig. 1 bis 3 sind oberhalb und unterhalb des Schienenträgers 1 Längsträger 8 mit Lagerbohrungen 7 für die Achsen 6 der Führungsrollen 5 erkennbar. Vom oberen Längsträger 8 führt ein senkrechter Stegträger 9 zum Längsträger. Der obere Längsträger 8 hat eine Ausnehmung für das Tragrad 3 zum Abrollen auf der Lauffläche la.In Fig. 2, the guide rollers are dashed at the top right and bottom left and the guide rollers at the bottom right and top left are drawn with solid lines, ie, the former are behind the rail support 1. Only these four, the two visible and the two invisible guide rollers 5 ensure that perfect guidance of the trolley 2 on the rail support 1. In FIGS. 1 to 3, longitudinal members 8 with bearing holes 7 for the axes 6 of the guide rollers 5 can be seen above and below the rail support 1. A vertical web support 9 leads from the upper side member 8 to the side member. The upper side member 8 has a recess for the support wheel 3 for rolling on the tread la.

In der Fig. 4 ist der Schienenträger 1 übertrieben stark gebogen gezeichnet. Diese Figur zeigt aber deutlich, daß etwaige in Fahrzeugmitte vorhandene Führungen - ob Spurkränze oder weitere Führungsrollen - zu Zwängungen führen.4, the rail support 1 is drawn in an exaggeratedly curved manner. However, this figure clearly shows that any guides present in the center of the vehicle - whether wheel flanges or other guide rollers - lead to constraints.

Beim Ausführungsbeispiel nach den Fig. 5 und 6 haben die Laufkatzen 2 unter dem am Stegträger 9 befestigten Längsträger 8 senkrechte Zapfen 11 für Lageraugen 12 eines Lastenträgers 13, der über die Laufkatzen 2 hinausragt und am Ende ösen 10 zum Einhängen langer Teile hat.In the embodiment according to FIGS. 5 and 6, the trolleys 2 have vertical pins 11 for bearing eyes 12 of a load carrier 13 which protrude above the trolleys 2 and have eyelets 10 at the end for hanging long parts under the longitudinal member 8 fastened to the web carrier 9.

Die Laufkatze nach Fig. 7 mit angedeutetem Fahrmotor 4 hat nur einen oberen Längsträger 8 mit zwei Stegträgern 9 für die unteren Führungsrollen 5, von denen die rechts gezeichnete vor dem Schienenträger 1 liegt.The trolley according to FIG. 7 with the traction motor 4 indicated has only one upper longitudinal beam 8 with two web carriers 9 for the lower guide rollers 5, of which the one shown on the right lies in front of the rail carrier 1.
