Abstract

The running gear has a rail which has web and flange sections, on opposite sides of which are travel and guide rollers in brackets joined together below the rail. Load-suspension equipment is provided on one or both brackets. The travel rollers (7) on one side of the rail are offset from those on the other side in the travel direction. The horizontal guide rollers (9) can be in pairs directly opposite each other, and can be pressed against the web (3) of the rail, and one of the travel rollers on one side can be directly motor-driven. The guide rollers can work in grooves in the web. The bracket arms (4a,b) can swing together and apart on a lengthwise axis below the rail, being held against the latter by the weight of the load.

Description

Die Erfindung betriffl ein Fahrwerk, insbesondere für Kettenzüge und/oder Schleppkabel, das einen aus Flansch- und Stegteilen bestehenden Fahrschienenquerschnitt umfaßt, mit sich gegenüberliegenden Laufrädem und Führungsrollen, die in seitlichen, unterhalb des Fahrschienenquerschnitts verbundenen Radträgern drehgelagert sind, wobei beidseitig der Schiene vor und hinter jedem sich auf den Flanschteilen aufstützenden Laufrad jeweils am Steg des Fahrschienenquerschnitts zur Führung anliegende Horizontalführungsrollenpaare angeordnet sind und an zumindest einem der Radträger eine Lasthängeeinrichtung vorgesehen ist.The invention relates to a trolley, in particular for chain hoists and / or trailing cables, which comprises a cross-section of the rail consisting of flange and web parts, with opposing wheels and guide rollers which are rotatably supported in side-mounted wheel carriers connected below the cross-section of the rail, with the rail on both sides in front and Behind each impeller that is supported on the flange parts, horizontal guide roller pairs lying on the web of the rail cross section for guidance are arranged and a load suspension device is provided on at least one of the wheel carriers.

Aus der DE 41 09 971 A1 ist ein gattungsgemäßes Fahrwerk mit Laufrädern auf beiden Seiten einer I-förmigen Fahrschiene bekannt, an der vordere und hintere seitliche, auf senkrechten Achsen gelagerte Führungsrollen einseitig anliegen. Dieses Fahrwerk läuft auch bei pendelnder Last stabil auf der Trägerschiene. Trotzdem ist die Fahrstabilität begrenzt; in kritischen Situationen neigt das Fahrwerk etwas zu Nickbewegungen und seitlichem Pendeln.From DE 41 09 971 A1 a generic undercarriage with running wheels on both sides of an I-shaped running rail is known, on which front and rear lateral guide rollers mounted on vertical axes rest on one side. This running gear runs stably on the carrier rail even with an oscillating load. Nevertheless, driving stability is limited; in critical situations, the chassis tends to pitch and swing sideways.

Es ist Aufgabe der vorliegenden Erfindung, ein Fahrwerk, insbesondere für Kettenzüge und/oder Schleppkabel anzugeben, das auch bei pendelnder Last stabil auf der Trägerschiene läuft, also nicht zu Nickbewegungen und seitlichem Pendeln des Fahrwerks neigt.It is an object of the present invention to provide a running gear, in particular for chain hoists and / or trailing cables, which runs stably on the support rail even with a swinging load, that is to say does not tend to pitching movements and lateral swinging of the running gear.

Die Lösung dieser Aufgabe ist erfindungsgemäß gekennzeichnet durch die im Patentanspruch 1 angegebenen Merkmale. Durch die kennzeichnenden Merkmale der Unteransprüche 2 bis 7 ist das Fahrwerk in vorteilhafter Weise weiter ausgestaltet.The solution to this problem is characterized by the features specified in claim 1. Due to the characterizing features of subclaims 2 to 7, the undercarriage is advantageously further developed.

Die Erfindung sieht vor, daß das oder die Laufräder auf der einen Seite der Schiene gegenüber dem oder den Laufrädern auf der anderen Seite der Schiene in Fahrtrichtung zueinander versetzt angeordnet sind.The invention provides that the one or more running wheels on one side of the rail are offset relative to the one or more running wheels on the other side of the rail in the direction of travel.

Das erfindungsgemäße Fahrwerk ermöglicht insbesondere bei pendelnder Last einen stabilen Lauf auf der Fahrschiene; Nickbewegungen und seitliches Pendeln des Fahrwerks werden durch den Versatz der Laufräder wirkungsvoll unterdrückt.The running gear according to the invention enables stable running on the running rail, in particular when the load is swinging; Pitching movements and lateral swinging of the chassis are effectively suppressed by the offset of the wheels.

Ein gleichmäßigerer Lauf des Fahrwerks auf der Fahrschiene wird erzielt, wenn die Horizontalführungsrollenpaare einander paarweise direkt gegenüberliegend angeordnet sind.A more even running of the running gear on the running rail is achieved if the horizontal guide roller pairs are arranged in pairs directly opposite one another.

Zweckmäßigerweise sollten die Horizontalführungsrollenpaare am Steg des Fahrschienenquerschnitts kraftbeaufschlagt anliegen, beispielsweise durch eine Federkraft hervorgerufen.The pairs of horizontal guide rollers should expediently bear on the web of the cross-section of the rail under the action of force, for example caused by a spring force.

Ein kompaktes und robustes Laufwerk mit einfachem Antriebsanbau ergibt sich, wenn bei zwei Laufrädern ein Laufrad unmittelbar motorisch angetrieben ist. Der Antrieb kann auf diese Weise weitestgehend wartungsfrei ausgeführt werden.A compact and robust drive with simple drive attachment results if one wheel is directly motor-driven with two wheels. In this way, the drive can be carried out largely maintenance-free.

Stabilitätsverbessernd wirkt es sich ferner aus, wenn die Führungsräder in am Steg des Fahrschienenquerschnitts angeordneten Führungsnuten geführt sind.It also improves stability if the guide wheels are guided in guide grooves arranged on the web of the rail cross section.

Die Laufstabilität des Fahrwerks läßt sich dadurch weiter verbessern, indem jeweils auf- oder zuschwenkbare Radträgerarme um eine sich in Richtung der Fahrschiene erstreckende und unter dem Fahrschienenquerschnitt verlaufende Achse schwenkbar gelagert sind, wobei auf Höhe oder unterhalb des gebildeten Gelenks der jeweils miteinander verbundenen Radträgerarme die Last an zumindest einem der Radträgerarme angreift und die Radträgerarme durch ein von der Last herrührendes Schließmoment von den am Steg beidseitig anliegenden Führungsrollen begrenzt am Fahrschienenquerschnitt eingeschwenkt gehalten sind. Außerdem ermöglicht es diese Maßnahme, das Fahrwerk im vormontierten Zustand mit wenigen Handgriffen an einer Fahrschiene mit korrespondierendem Fahrschienenquerschnitt aufzuhängen. Durch die sich selbsttätig spielfrei einstellenden Führungsrollen, die beidseitig am Steg anliegen, ist ein gleichmäßiger Parallellauf der Laufrollen sichergestellt, wodurch wiederum der Rollwiderstand und damit der Verschleiß der Laufrollen gering sind; auch die Führungsrollen unterliegen dabei einem sehr geringen Verschleiß. Das durch die Last eingeschwenkt gehaltene Fahrwerk erweist sich insbesondere bei Kurven als sehr vorteilhaft, da hierdurch bei Kurvenfahrten der Parallellauf der Laufrollen verbessert wird. Dabei sorgen die ständig anliegenden Führungsrollen auch bei pendelnder Last für eine stabile Führung des Fahrwerks. Durchmesseränderungen der Laufräder und der Führungsrollen aufgrund von unvermeidlichem Abrieb werden innerhalb eines großen Toleranzbereiches dadurch ausgeglichen, daß sich das Fahrwerk selbsttätig an die Fahrschiene anpaßt.The running stability of the undercarriage can be further improved in that wheel carrier arms which can be swiveled in or out are pivotably mounted about an axis which extends in the direction of the rail and extends under the rail cross-section, the load being at the level or below the joint formed of the wheel carrier arms which are in each case connected to one another engages on at least one of the wheel carrier arms and the wheel carrier arms are held in a pivoted manner on the guide rail cross section to a limited extent by a closing torque resulting from the load by the guide rollers resting on both sides of the web. In addition, this measure enables the running gear in the preassembled state to be carried out on a running rail with a corresponding action in a few simple steps Hang up the cross-section of the rails. The self-adjusting guide rollers, which rest against the web on both sides, ensure that the rollers run evenly in parallel, which in turn reduces rolling resistance and therefore wear on the rollers; the guide rollers are also subject to very little wear. The undercarriage pivoted in by the load proves to be very advantageous, particularly when cornering, since this improves the parallel running of the rollers when cornering. The constantly attached guide rollers ensure stable guidance of the undercarriage even when the load is swinging. Changes in the diameter of the running wheels and the guide rollers due to unavoidable abrasion are compensated for within a large tolerance range by the fact that the undercarriage automatically adapts to the running rail.

Mit der Erfindung wird ferner vorgeschlagen, das Verhältnis aus dem vertikalen Abstand M der Achsen der Laufräder und dem horizontalen Abstand L der Laufräder von der Schwenkachse größer als 5 und kleiner als 10 ist.The invention further proposes that the ratio of the vertical distance M of the axes of the impellers and the horizontal distance L of the impellers from the pivot axis is greater than 5 and less than 10.

An embodiment of the invention is shown in the drawing and will be described in more detail below. Show it

a front view of a chassis and
Fig. 2
2 shows a plan view of the undercarriage according to FIG. 1.

In Fig. 1 ist in Vorderansicht ein Fahrwerk dargestellt, das eine Fahrschiene 1 umfaßt, die aus Flanschteilen 2 und einem Steg 3 besteht. Das Fahrwerk selbst weist zwei Radträgerarme 4a, 4b auf, die als Rahmen 5a, 5b ausgebildet sind. Die Rahmen 5a, 5b sind um eine sich in Richtung der Fahrschiene 1 erstreckende und unter dem Fahrschienenquerschnitt verlaufende Achse 6 gegenläufig schwenkbar gelagert, was ein Auf- oder Zuschwenken der Rahmen 5a, 5b ermöglicht. Selbstverständlich ist das nur eine vorteilhafte Ausführungsform; die Radträgerarme 4a, 4b können auch starr miteinander verbunden und auf einen festen Abstand eingestellt sein. Darüberhinaus ist auch eine Kombination dieser beiden Varianten denkbar, die darin besteht, daß die schwenkbaren Radträgerarme 4a, 4b nach dem Einschwenken an der Fahrschiene 1 so fixiert werden, daß eine starre Verbindung zwischen den Radträgerarmen 4a, 4b hergestellt ist.In Fig. 1, a chassis is shown in front view, which comprises a rail 1, which consists of flange parts 2 and a web 3. The undercarriage itself has two wheel carrier arms 4a, 4b, which are designed as frames 5a, 5b. The frames 5a, 5b are pivotally mounted in opposite directions about an axis 6 which extends in the direction of the rail 1 and runs below the rail cross-section, which enables the frames 5a, 5b to be pivoted open or closed. Of course, this is only an advantageous embodiment; the wheel carrier arms 4a, 4b can also be rigidly connected to one another and set at a fixed distance. In addition, a combination of these two variants is also conceivable, which consists in that the pivotable wheel carrier arms 4a, 4b are fixed on the travel rail 1 after pivoting in such a way that a rigid connection is established between the wheel carrier arms 4a, 4b.

Fig. 1 läßt erkennen, daß im oberen Bereich der Rahmen 5a, 5b ein Paar sich gegenüberliegender Laufräder 7 angeordnet sind, deren Drehachsen horizontal verlaufen und in den Rahmen 5a, 5b abgestützt sind. Von den beiden Laufrädern 7 wird ein Laufrad unmittelbar durch einen Motor 7a angetrieben. Die Laufräder 7 rollen . auf den unteren Flanschteillaufflächen 8 ab. Die Rahmen 5a, 5b nehmen neben den im Rahmen 5a, 5b jeweils mittig angeordneten Laufrädern 7 vor und hinter den Laufrädern 7 angeordnete Horizontalführungsrollenpaare 9, 9 auf, die aus einzelnen Führungsrollen 9 bestehen, welche vertikal drehgelagert in dem Rahmen 5a, 5b abgestützt sind. Während die Laufräder 7 sich auf den unteren Flanschteilen 2 abstützen, liegen die Führungsrollen 9 paarweise am Steg 3 der Fahrschiene 1 an. Aus der Fig. 1 geht hervor. daß die Rahmen 5a. 5b so weit über den jeweiligen Flanschteil 2 des Fahrschienenquerschnitts der Fahrschiene 1 eingeschwenkt sind, daß die Laufräder 7 sich unmittelbar in Stegnähe des Stegs 3 bewegen. Auf Höhe des gebildeten Gelenks 10 der beiden miteinander verbundenen Rahmen 5a, 5b greift die Last an der Achse 6 an; das unterhalb der Fahrschiene 1 gebildete Gelenk ist also zugleich Aufhängemitte für die aufzuhängende Last.Fig. 1 shows that in the upper region of the frame 5a, 5b a pair of opposing wheels 7 are arranged, the axes of rotation of which run horizontally and are supported in the frame 5a, 5b. Of the two impellers 7, an impeller is driven directly by a motor 7a. The wheels 7 roll. on the lower flange part contact surfaces 8. The frames 5a, 5b accommodate, in addition to the wheels 7, which are arranged centrally in the frames 5a, 5b, in front of and behind the wheels 7, horizontal guide roller pairs 9, 9, which consist of individual guide rollers 9, which are supported in the frame 5a, 5b in a vertically rotatably mounted manner. While the running wheels 7 are supported on the lower flange parts 2, the guide rollers 9 rest in pairs on the web 3 of the running rail 1. 1 shows. that the frame 5a. 5b are pivoted so far over the respective flange part 2 of the cross-section of the running rail 1 that the running wheels 7 move directly in the vicinity of the web of the web 3. At the level of the formed joint 10 of the two interconnected frames 5a, 5b, the load acts on the axis 6; the joint formed underneath the running rail 1 is at the same time a suspension center for the load to be suspended.

Die Last erzeugt in den Rahmen 5a, 5b ein Schließmoment, das ein Zuschwenken der Rahmen 5a, 5b bewirkt, durch das die Führungsrollen 9 am Steg 3 des Fahrschienenquerschnitts eingeschwenkt gehalten werden. Die Winkelstellung zwischen den Rahmen 5a, 5b wird in Fig. 1 durch die am Steg 3 beidseitig anliegenden Führungsrollen 9 begrenzt; die Anlage der Führungsrollen 9 erfolgt kraftbeaufschlagt durch die Last selbst.The load generates a closing moment in the frames 5a, 5b, which causes the frames 5a, 5b to pivot, by means of which the guide rollers 9 are held pivoted in on the web 3 of the cross-section of the running rail. The angular position between the frames 5a, 5b is limited in FIG. 1 by the guide rollers 9 resting on the web 3 on both sides; the guide rollers 9 are placed under the force of the load itself.

Das Verhältnis aus dem vertikalen Abstand M der Achsen der Laufräder (7) und dem horizontalen Abstand L der Laufräder (7) von der Achse (Schwenkachse) 6 ist größer als 5 und kleiner als 10.The ratio of the vertical distance M of the axes of the impellers (7) and the horizontal distance L of the impellers (7) from the axis (swivel axis) 6 is greater than 5 and less than 10.

Alternativ zu der dargestellten Fahrschiene 1 ist es auch möglich, am Steg 3 sich in Längsrichtung der Schiene 1 erstreckende Führungsnuten vorzusehen, in denen die Führungsräder 9 geführt sind. Durch die zusätzlich angeordneten Führungsnuten wird bei pendelnder Last eine noch stabilere Führung des Fahrwerks sichergestellt.As an alternative to the travel rail 1 shown, it is also possible to provide guide grooves on the web 3 which extend in the longitudinal direction of the rail 1 and in which the guide wheels 9 are guided. The additionally arranged guide grooves ensure an even more stable guidance of the chassis when the load is swinging.

In Fig. 2 ist eine Draufsicht auf das Fahrwerk mit Fahrschiene gemäß Fig. 1 dargestellt. Das Laufrad 7 des einen Rahmens 5a oder 5b ist gegenüber dem Laufrad 7 des anderen Rahmens 5b bzw. 5a in Fahrtrichtung versetzt angeordnet, wie Fig. 2 deutlich zu entnehmen ist.FIG. 2 shows a top view of the undercarriage with the travel rail according to FIG. 1. The impeller 7 of the one frame 5a or 5b is offset from the impeller 7 of the other frame 5b or 5a in the direction of travel, as can be clearly seen in FIG. 2.
