Abstract

The invention relates to a chassis (1) for a cable or pipeline trolley (2), for traveling along a carrier rail, the chassis including at least one pair of carrier rollers (3) having a horizontal axis of rotation and at least one pair of guide rollers (4) having a vertical axis of rotation. The disadvantage of known chassis of this type is that they jolt at uneven sections of the carrier rail and a significant supply of replacement parts is required for repairs. The aim of the invention is to develop a chassis with improved driving characteristics, whilst at the same time reducing production and inventory costs. To achieve this, the carrier rollers (3) and guide rollers (4) are essentially arranged symmetrically to a vertical axis.

Description

Fahrwerk für einen Leitungswagen Suspension for a cable trolley
Die Erfindung betrifft ein Fahrwerk für einen Leitungswagen zum Verfahren längs einer Tragschiene nach dem Oberbegriff des Anspruchs 1 sowie einen mit einem derartigen Fahrwerk ausgestatteten Leitungs wagen.The invention relates to a chassis for a cable trolley to process along a support rail according to the preamble of claim 1 and a coach equipped with such a chassis.
Ein Leitungswagen, der ein solches Fahrwerk beinhaltet ist Gegenstand der DE 44 36 520 Cl und auch der DE 44 36 519 C2 sowie der DE 26 28 112 C2. Entsprechende Leitungswagen finden beispielsweise bei Schleppleitungsvorrichtungen Verwendung oder auch bei Kranauslegern, also bei allen Anwendungen, bei denen Strom- und/oder Gasführende Leitungen entlang einer Schiene zu einem beweglichen Verbraucher, z. B. einer Laufkatze eines Krans, geführt werden müssen. Die genannten Druckschriften beschreiben sowohl passive Leitungswagen, also solche ohne eigenen Antrieb, als auch aktive Leitungs wagen, also solche mit eigenem Antrieb.A cable trolley, which includes such a chassis is the subject of DE 44 36 520 Cl and also DE 44 36 519 C2 and DE 26 28 112 C2. Corresponding cable car find, for example, in towing line devices use or crane jibs, so in all applications in which power and / or gas-carrying lines along a rail to a mobile consumer, eg. B. a trolley of a crane, must be performed. The cited documents describe both passive cable trolleys, ie those without their own drive, as well as active trolley, ie those with their own drive.
Die Leitungswagen bestehen in der Regel aus drei Hauptelementen, nämlich dem oder den Fahrwerken, dem Mittelteil bzw. Mittelblech und der eigentlichen Aufhängevorrichtung für die zu transportierenden Leitungen. Die Fahrwerke hängen an in der Regel Doppel-T-förmigen Laufschienen, welche auch als I-Träger bezeichnet werden. An der Unterseite der Fahrwerke ist das Tragblech befestigt, an dessen Unterseite wiederum die eigentliche Aufhängevorrichtung für die zu transportierenden Leitungen befestigt ist. In der Regel ist ein Leitungswagen mit zwei Fahrwerken bzw. einem Fahrwerk, bestehend aus vier Seitenschildern, ausgestattet. Von denen jedes über ein Paar Tragrollen verfügt, welche einander gegenüberliegend und mit im wesentlichen horizontaler Drehachse auf der Tragschiene verfahren und die Gewichtskraft aufnehmen. Ferner weist jedes Fahrwerk ein Paar einander gegenüberliegende Führungsrollen mit im wesentlichen vertikaler Drehachse auf, die schwächer dimensioniert sind als die Tragrollen, da sie nicht das Gewicht des Leitungswagens aufnehmen müssen, sondern nur der Führung entlang des vertikalen Mittelschenkels der I-förmigen Tragschiene dienen. Bei allen bekannten Fahrwerken für Leitungswagen ist jeweils eine Tragrolle und eine Führungsrolle auf einer Trägerplatte angeordnet und die beiden Trägerplatten sind zusammengeschraubt. Aus Symmetriegründen muss also jede Trägerplatte spiegelsymmetrisch zur anderen Trägerplatte ausgestaltet sein, so dass zwei verschiedene Trägerplatten hergestellt und auf Lager gehalten werden müssen, nämlich eine linke und eine rechte.The cable trolleys usually consist of three main elements, namely the or the trolleys, the middle part or center plate and the actual suspension for the cables to be transported. The trolleys hang on usually double T-shaped rails, which are also referred to as I-beam. At the bottom of the trolleys, the support plate is attached, on its underside, in turn, the actual suspension for the cables to be transported is attached. As a rule, a cable trolley with two trolleys or a chassis, consisting of four side plates, equipped. Each of which has a pair of support rollers, which move opposite each other and with a substantially horizontal axis of rotation on the support rail and absorb the weight. Furthermore, each chassis has a pair of opposing guide rollers with a substantially vertical axis of rotation, which are dimensioned weaker than the support rollers, since they do not have to take the weight of the festoon carriage, but only serve the guide along the vertical center leg of the I-shaped mounting rail. In all known trolleys for cable trolleys each a support roller and a guide roller is arranged on a support plate and the two support plates are screwed together. For reasons of symmetry, therefore, each support plate must be configured mirror-symmetrically to the other support plate, so that two different carrier plates must be produced and kept in stock, namely a left and a right.
Ferner weisen die aus dem Stand der Technik bekannten Fahrwerke für Leitungswagen den Nachteil auf, dass sie bei Unebenheiten in der Tragschiene holpern, weil beide Tragrollen die Unebenheit zur gleichen Zeit passieren. Außerdem ist die Führung dieser bekannten Fahrwerke an der Tragschiene nicht optimal, da die Führungsrollen versetzt zu den Tragrollen angeordnet sein müssen.Furthermore, the known from the prior art suspensions for cable trolleys have the disadvantage that they bump in unevenness in the support rail, because both support rollers pass the unevenness at the same time. In addition, the leadership of these known trolleys on the mounting rail is not optimal, since the guide rollers must be arranged offset to the support rollers.
Es besteht daher die Aufgabe, ein Fahrwerk für einen Leitungswagen sowie einen mit einem solchen Fahrwerk ausgestatteten Leitungswagen so weiterzubilden, dass bessere Fahreigenschaften erzielt werden, wobei gleichzeitig eine Kostenreduzierung in Herstellung und Lagerhaltung stattfinden soll.There is therefore the task of developing a chassis for a cable trolley and equipped with such a chassis trolley so that better driving characteristics are achieved, at the same time a cost reduction in production and storage should take place.
Gelöst wird diese Aufgabe mit den kennzeichnenden Merkmalen des Anspruchs 1. Vorteilhafte Ausgestaltungen sind den Unteransprüchen 2 und 3 entnehmbar. Ein mit einem erfindungsgemäßen Fahrwerk ausgestatteter Leitungswagen dem Anspruch 4.This object is achieved with the characterizing features of claim 1. Advantageous embodiments are the dependent claims 2 and 3 can be removed. A equipped with a chassis according to the invention cable trolley according to claim 4.
Ein Ausführungsbeispiel der Erfindung wird im folgenden unter Bezugnahme auf die begleitenden Zeichnungen näher erläutert. Diese zeigen:An embodiment of the invention will be explained in more detail below with reference to the accompanying drawings. These show:

Fig. 6: eine Darstellung des Fahrwerks gemäß Figuren 4 und 5 von oben.6 shows an illustration of the chassis according to FIGS. 4 and 5 from above.
Der in den Figuren 1 bis 3 dargestellte Leitungswagen (2) besteht aus einem Mittelteil bzw. Mittelblech (9), welches zwei Fahrwerke (1) mit einer Trägervorrichtung (10) für die zu transportierenden (nicht dargestellten) Elektrizitäts- und/oder Gasleitungen verbindet. An den in Fahrtrichtung einander gegenüberliegenden Enden weist das Mittelblech (9) Zellpuffer (11) auf, die bei einem Aufprall benachbarter Leitungswagen dämpfend wirken und einen Stoßpuffer bilden. An seiner Oberseite weist das Mittelblech (9) im dargestellten Ausführungsbeispiel 2, in Fahrtrichtung hintereinander angeordnete Fahrwerke (1) auf. Diese Fahrwerke (1) sind identisch ausgebildet und in den Figuren 4 bis 6 im Detail dargestellt.The cable trolley (2) shown in Figures 1 to 3 consists of a central part or center plate (9), which connects two carriages (1) with a support device (10) for the transportable (not shown) electricity and / or gas lines , To the In the direction of travel opposite ends, the center plate (9) cell buffer (11), which act in a collision impact of adjacent cable trolleys and form a shock buffer. On its upper side, the middle plate (9) in the illustrated embodiment 2, in the direction of travel successively arranged trolleys (1). These suspensions (1) are identical in design and shown in detail in Figures 4 to 6.
Jedes Fahrwerk (1) weist zwei einander gegenüberliegende Trägerplatten (6) und (7) aus Stahl oder ggf. aus einem geeigneten Kunststoff auf, welche in der Draufsicht sich nach unten verjüngend ausgebildet sind und in ihrem unteren Bereich mehrere Verbindungsbohrungen (12) aufweisen, durch welche Schraubverbindungen (13) geführt sind, um die beiden Trägerplatten (6) und (7) miteinander zu verbinden, wie es am besten aus Figur 5 ersichtlich ist. An ihrem Oberbereich tragen die beiden Trägerplatten (6) und (7) jeweils eine Tragrolle (3) mit im wesentlichen horizontaler Drehachse und eine Führungsrolle (4) mit im wesentlichen vertikaler Drehachse.Each chassis (1) has two mutually opposite support plates (6) and (7) made of steel or possibly of a suitable plastic, which are tapered downwards in plan view and have in its lower region a plurality of connecting holes (12), through which screw connections (13) are guided in order to connect the two support plates (6) and (7) together, as is best seen in FIG. At their upper region, the two support plates (6) and (7) each carry a support roller (3) with a substantially horizontal axis of rotation and a guide roller (4) with a substantially vertical axis of rotation.
Allerdings sind die beiden Tragrollen (3) im zusammengeschraubten Zustand der beiden Trägerplatten (6) und (7) nicht einander gegenüberliegend angeordnet, ebenso wenig die Führungsrollen (4). Vielmehr liegt die linke Tragrolle (3) der rechten Führungsrolle (4) gegenüber und die rechte Tragrolle (3) der linken Führungsrolle (4) wie es in den Figuren 4 bis 6 ersichtlich ist, insbesondere in Figur 6. Im Gegensatz zu den aus dem Stand der Technik bekannten Fahrwerken ist die Anordnung der Trag- und Führungsrollen (3) und (4) also nicht spiegelsymmetrisch zu einer Ebene längs der (nicht dargestellten) Tragschiene, sondern vielmehr achsensymmetrisch zu einer vertikalen Achse (5), die etwa in der Mitte des Fahrwerks (1) liegt.However, the two support rollers (3) in the bolted state of the two support plates (6) and (7) are not arranged opposite to each other, nor the guide rollers (4). Rather, the left support roller (3) of the right guide roller (4) opposite and the right support roller (3) of the left guide roller (4) as can be seen in Figures 4 to 6, in particular in Figure 6. In contrast to the Prior art known suspension is the arrangement of the support and guide rollers (3) and (4) so not mirror-symmetrical to a plane along the support rail (not shown), but rather axisymmetric to a vertical axis (5), which is approximately in the middle of the chassis (1) is located.
Wie aus den Figuren 4 bis 6 ersichtlich ist können damit die beiden Trägerplatten (6) und (7) identisch zueinander ausgebildet werden. Mit anderen Worten besteht zwischen der linken Trägerplatte (6) und der rechten Trägerplatte (7) kein Unterschied mehr; es handelt sich um vollständig austauschbare Einzelteile, die auch nur einmal auf Lager vorgehalten werden müssen.As can be seen from Figures 4 to 6 so that the two support plates (6) and (7) are formed identical to each other. In other words, there is no difference between the left support plate (6) and the right support plate (7); These are completely interchangeable parts that need to be stocked only once.
Im dargestellten Ausführungsbeispiel weist das Fahrwerk (1) noch zusätzliche Stützrollen (8) bzw. Gegendruckrollen auf, welche eine im wesentlichen horizontale Drehachse aufweisen und an den Tragerplatten (6) und (7) angeordnet sind Diese dienen dazu, das Fahrwerk (1) gegen ein Abheben von der Tragschiene zu sichernIn the illustrated embodiment, the chassis (1) on additional support rollers (8) or counter-pressure rollers, which have a substantially horizontal axis of rotation and are arranged on the support plates (6) and (7) These serve to secure the chassis (1) against lifting from the mounting rail
Das erfindungsgemaße Fahrwerk weist jedoch auch in Betπeb erhebliche Vorteile gegenüber den aus dem Stand der Technik bekannten Fahrwerken auf. Da die Tragrollen (3) nicht einander gegenüber, sondern in Fahrtrichtung zueinander versetzt angeordnet sind, werden Unebenheiten des Tragerprofils wesentlich besser abgefangen und ausgeglichen, weil in der Regel immer eine Tragrolle (3) zuverlässig auf dem Tragerprofil aufliegt. Ferner ergibt sich eine verbesserte Fuhrung des Fahrwerks (1) und damit des Leitungswagens (2) durch die direkte Gegenüberstellung von Tragrolle (3) und Fuhrungsrolle (4). Außerdem ergibt sich ein verbesserter Kraftfluss zwischen den Fuhrungsrollen (4) und dem Mittelbleich (9) aufgrund eines geπngeren seitlichen Versatzes der Krafteeinleitung in das Mittelblech Schließlich ist als Vorteil die Gewichtsreduktion durch eine entsprechende Teilereduktion zu nennen und damit geπngere Herstellkosten sowie geringere Laufgerausche. Außerdem wird die Montage und Demontage aufgrund der geπngeren Anzahl der benotigten Teile vereinfacht und es werden Fehler bei der Monatage vermieden, da die beiden Tragerplatten (6) und (7) zueinander identisch ausgebildet sind However, the suspension according to the invention also has considerable advantages in terms of the bogies known from the prior art. Since the support rollers (3) are not offset from each other, but offset in the direction of travel to each other, unevenness of the support profile are much better intercepted and compensated, because usually always a support roller (3) rests reliably on the carrier profile. Furthermore, there is an improved leadership of the chassis (1) and thus the festooned carriage (2) by the direct comparison of carrier roller (3) and Fuhrungsrolle (4). In addition, there is an improved power flow between the guide rollers (4) and the middle bleaching (9) due to a more lateral offset of the force introduction into the center plate Finally, to give an advantage weight reduction by a corresponding reduction in parts and thus niger manufacturing costs and lower Laufgerausche. In addition, the assembly and disassembly is simplified due to the larger number of benotigten required parts and errors in the Monatage be avoided because the two Tragerplatten (6) and (7) are identical to each other
