Abstract

The system has a rail comprising flange (2) and web (3) sections, along which opposite travel wheels (7) and horizontal guide rollers (9) run. These rotate in brackets (4a,b) hinging together below the rail. The guide rollers are situated before and after the travel wheels which run along the flanges on opposite sides of the rail web. The guide rollers work in guides (11) running in the lengthwise direction between the flanges, and which are typically formed by grooves. The groove cross-section can match that of the guide rollers, being typically of trapezium shape with the edges radiused. The roller edges can run against the sloping groove sides, leaving a free space between the roller underside and the groove bottom. The rollers can be thrust under pressure into the grooves.

Description

Die Erfindung betrifft ein Fahrwerk, insbesondere für Kettenzüge, Lastaufnahmemittel und/oder Schleppkabel, das einen aus Flansch- und Stegteilen bestehenden Fahrschienenquerschnit umfaßt, an dem sich gegenüberliegende Laufräder und Führungsrollen abstützen, die in seitlichen, unterhalb des Fahrschienenquerschnitts verbundenen Radträgern drehgelagert sind und von denen die Führungsrolle beidseitig der Schiene vor und hinter jedem sich auf den Flanschteilen aufstützenden Laufrad jeweils am Fahrschienenquerschnitt zur Führung anliegende Horizontalführungsrollenpaare sind, an denen zumindest einer der Radträger eine Lasthängeeinrichtung aufweist.The invention relates to a trolley, in particular for chain hoists, load suspension devices and / or trailing cables, which comprises a rail cross-section consisting of flange and web parts, on which opposing running wheels and guide rollers are supported, which are rotatably mounted in lateral wheel carriers connected below the rail cross-section and of which the guide roller on both sides of the rail in front of and behind each impeller which is supported on the flange parts are horizontal guide roller pairs which are in contact with the guide rail cross section and on which at least one of the wheel carriers has a load suspension device.

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 9 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 9, the undercarriage is advantageously further developed.

Die Lösung sieht vor, daß die Führungsräder in zumindest an einer Seite des Stegs des Fahrschienenquerschnitts angeordneten Führungen zumindest abschnittsweise geführt sind. Das Fahrwerk ermöglicht insbesondere bei pendelnder Last einen stabilen Lauf auf der Fahrschiene; Nickbewegungen und seitliches Pendeln des Fahrwerks werden durch die Führungen wirkungsvoll verhindert.The solution provides that the guide wheels are guided at least in sections in guides arranged at least on one side of the web of the rail cross section. The running gear enables stable running on the running rail, especially when the load is swinging; The guides effectively prevent pitching movements and lateral swinging of the undercarriage.

Zur Vereinfachung der Herstellung sind die Führungen als Führungsnuten ausgebildet.To simplify production, the guides are designed as guide grooves.

Eine stabile und ruhige Führung wird dadurch erzielt, daß die Kontur der Führungsnuten zur Form der in den Führungsnuten laufenden Führungsräder komplementär ist.A stable and quiet guidance is achieved in that the contour of the guide grooves is complementary to the shape of the guide wheels running in the guide grooves.

Es wird vorgeschlagen, daß der Querschnitt der Führungsnuten im wesentlichen trapezförmig ausgebildet ist, um zusätzlich einen möglichst geringen Verschleiß der Führungsräder zu erzielen.It is proposed that the cross-section of the guide grooves be substantially trapezoidal in order to additionally minimize wear on the guide wheels.

Insbesondere wird vorgeschlagen, daß die Kanten der Führungsräder abgerundet ausgebildet sind, also nur teilweise auf den Flächen der Führungsnuten laufen.In particular, it is proposed that the edges of the guide wheels are rounded, so that they run only partially on the surfaces of the guide grooves.

Eine Stabilisierung der Führung bei geringem Verschleiß ergibt sich speziell dann, wenn die Rundung der Kanten der Führungsräder und die Form der trapezförmigen Führungsnuten derart ausgebildet ist, daß die Führungsräder auf den Schrägen der trapezförmigen Führungsnuten laufen, unter Belassung eines Zwischenraums zwischen den Führungsrädem und dem mittleren Bereich der zugehörigen Führungsnut.The guide is stabilized with little wear and tear if the rounding of the edges of the guide wheels and the shape of the trapezoidal guide grooves are designed such that the guide wheels run on the slopes of the trapezoidal guide grooves, leaving a space between the guide wheels and the middle one Area of the associated guide groove.

Ein gleichmäßiger Lauf wird auch dadurch erreicht, daß die Horizontalführungsrollenpaare in den Führungen am Steg des Fahrschienenquerschnitts kraftbeaufschlagt anliegen, beispielsweise durch eine Federkraft hervorgerufen.A smooth run is also achieved in that the horizontal guide roller pairs in the guides on the web of Contact rail cross section apply force, caused for example by a spring force.

Der Lauf wird insbesondere dadurch verbessert, daß paarweise 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 in den Führungen am Steg beidseitig anliegenden Führungsrollen begrenzt am Fahrschienenquerschnitt eingeschwenkt gehalten sind.The run is particularly improved in that wheel carrier arms which can be swiveled in or closed in pairs are pivotably mounted about an axis which extends in the direction of the rail and extends below the rail cross-section, the load on at least one at the level or below the joint formed in each case of the wheel carrier arms which are connected to one another the wheel carrier arms engages 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 originating from the load by the guide rollers resting on both sides in the guides on the web.

3 shows an enlarged section of the guide grooves together with the guide wheels 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 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 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 pivotably mounted about an axis 6 which extends in the direction of the travel rail 1 and runs below the cross section of the travel rail, 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. 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 running 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 10 ist also zugleich Aufhängemittel 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 impellers 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 that the frames 5a, 5b are pivoted so far over the respective flange part 2 of the cross-section of the rail 1 that the running wheels 7 move directly in the vicinity 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 10 formed below the running rail 1 is thus at the same time a suspension means 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.

In Fig. 2 ist eine Draufsicht auf das Fahrwerk mit Fahrschiene gemäß Fig. 1 dargestellt.FIG. 2 shows a top view of the undercarriage with the travel rail according to FIG. 1.

Wie Fig. 1 zu entnehmen ist, sind am Steg 3 der dargestellten Fahrschiene 1 sich in Längsrichtung der Schiene 1 erstreckende seitliche Führungen 11 für die Führungsräder 9 in Form von Führungsnuten 11a ausgebildet, in denen die Führungsräder 9 zur Erzeugung eines stabilen Fahrwerklaufs kraftbeaufschlagt geführt sind.As can be seen in FIG. 1, lateral guides 11 for the guide wheels 9, which extend in the longitudinal direction of the rail 1, are formed on the web 3 of the illustrated guide rail 1 in the form of guide grooves 11a, in which the guide wheels 9 are guided to generate a stable running gear .

Fig. 3 zeigt einen vergrößerten Ausschnitt der Führungsnuten 11a zusammen mit einem in die Führungsnuten 11a eingreifenden Führungsrad 9 mit abgerundeten Kanten 12 im Querschnitt. Wie Fig. 3 zu entnehmen ist, ist der Querschnitt der Führungsnuten 11a im wesentlichen trapezförmig mit zwei Schrägen 13 und einem Trapezdach 14 ausgebildet, wobei die Rundungen der Kanten 12 der Führungsräder 9 auf den Schrägen 13 der trapezförmigen Führungsnuten 11a laufen, und zwar unter Belassung eines Zwischenraums 15 zwischen dem mittleren Bereich des Führungsrads 9 und dem Trapezdach 14, d.h. die Berührungsflächen zwischen Führungsrad 9 und Führungsnut 11a sind relativ klein, was für einen verringerten Rollwiderstand des Fahrwerks sorgt. Selbstverständlich ist es auch möglich, die Kontur der Führungsnut 11a zur Form der in den Führungsnut 11a laufenden Führungsräder 9 zueinander nahezu komplementär auszubilden, um mit vergrößertem Aufwand die Führungsgenauigkeit weiter zu verbessern. Dem dient auch eine Ausführungsform, bei der die Laufrad 7 auf der einen Seite der Schiene 1 gegenüber dem Laufrad 7 auf der anderen Seite der Schiene 1 in Fahrtrichtung zueinander versetzt angeordnet sind.Fig. 3 shows an enlarged section of the guide grooves 11a together with a guide wheel 9 engaging in the guide grooves 11a with rounded edges 12 in cross section. As can be seen in FIG. 3, the cross section of the guide grooves 11a is essentially trapezoidal with two bevels 13 and a trapezoidal roof 14, the rounded edges 12 of the guide wheels 9 running on the bevels 13 of the trapezoidal guide grooves 11a, while leaving them an intermediate space 15 between the central region of the guide wheel 9 and the trapezoidal roof 14, ie the contact surfaces between the guide wheel 9 and guide groove 11a are relatively small, which ensures a reduced rolling resistance of the chassis. Of course, it is also possible to make the contour of the guide groove 11a almost complementary to the shape of the guide wheels 9 running in the guide groove 11a in order to further improve the guiding accuracy with increased effort. This is also served by an embodiment in which the impeller 7 on one side of the rail 1 is offset from one another in the direction of travel relative to the impeller 7 on the other side of the rail 1.

Das Verhältnis aus dem vertikalen Abstand M der Achsen der Laufräder 7 und dem horizontalen Abstand L der Laufräder 7 von der Achse 6 (Schwenkachse) ist größer als 3 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 6 (swivel axis) is greater than 3 and less than 10.
