Description

Die Erfindung betrifft ein Fahrwerk für Hebezeuge, insbesondere für auf Einschienenflanschträgern geführte Hebezeuge, wobei die Einschienenflanschträger-Fahrwege neben geraden Abschnitten Höhen- und/oder Seitenkurven-Abschnitte aufweisen, mit sich gegenüberliegenden Seitenschildern, an denen jeweils zumindest ein Laufrad gelagert ist und Paare von Seitenführungsrollen, zwischen denen die Laufräder angeordnet sind, sowie mit einen Fahrantrieb und einer Kurvenfahreinrichtung, die mittels Federn gegen den Einschienenflanschträger anstellbar ist.The invention relates to a trolley for hoists, in particular for hoists guided on monorail flange supports, the monorail flange guideways in addition to straight sections having height and / or side curve sections, with opposing side plates, on each of which at least one impeller is mounted and pairs of side guide rollers , between which the wheels are arranged, and with a travel drive and a cornering device which can be adjusted by means of springs against the monorail flange carrier.

Ein derartiges Fahrwerk ist bekannt (DE-41 09 971 A1) und dient dem Transport von Lasten, Gütern und/oder Personen auf ebenen und geneigten Einschienen-Kurvenbahnen bei Doppel-T- und kastenförmigem Trägerprofil mit beliebigem Flanschprofil. Obwohl sich das bekannte Einschienenbahn-Unterflansch-Fahrwerk bewährt, treten dann Problem beim Einsatz des bekannten Fahrwerks auf, wenn der Krümmungsradius der Bahn von der horizontalen in die vertikale Ebene übergeht. Es ist daher mit dem bekannten Fahrwerk noch nicht möglich, alle Fahrbahnformen zu befahren.Such a chassis is known (DE-41 09 971 A1) and is used to transport loads, goods and / or people on flat and inclined monorails with double-T and box-shaped support profiles with any flange profile. Although the known monorail underflange undercarriage has proven itself, problems arise with the use of the known undercarriage when the radius of curvature of the track changes from the horizontal to the vertical plane. It is therefore with the known chassis not yet possible to drive on all road types.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, die Durchfahrt von Kurven in horizontaler und vertikaler Ebene zu ermöglichen, wobei gleichzeitig die Unterseite des Fahrflansches (z.B. zum Einsatz eines Reibradantriebs) freibleibt und nicht durch z.B. eine Schraubenfeder belegt wird.The present invention has for its object to enable the passage of curves in a horizontal and vertical plane, while the underside of the travel flange (e.g. for use of a friction wheel drive) remains free and not by e.g. a coil spring is occupied.

Die gestellte Aufgabe wird auf der Grundlage der eingangs bezeichneten Gattung erfindungsgemäß dadurch gelöst, daß die Kurvenfahreinrichtung an zumindest einem Seitenschild als drehgelagerter, gefederter einarmiger Schwenkhebel ausgebildet ist, an dessen freiem Schwenkhebel-Ende eine Zusatz-Seitenführungsrolle drehgelagert ist. Das Führungssystem arbeitet somit unabhängig von der Form des Trägers in horizontalen und vertikalen Ebenen bzw. Kurven. Ferner wird durch die Erfindungsmaßnahme die Möglichkeit geschaffen, alle Fahrbahnformen zu befahren.The stated object is achieved according to the invention on the basis of the type described at the outset in that the cornering device is designed on at least one side plate as a pivoted, spring-loaded, single-arm pivoting lever, on the free end of which pivoting arm an additional side guide roller is pivoted. The guidance system therefore works in horizontal and vertical planes or curves regardless of the shape of the carrier. Furthermore, the measure of the invention creates the possibility of driving on all types of lanes.

Nach weiteren Merkmalen wird vorgeschlagen, daß der Schwenkhebel mit einem Gabelende auf einer Achse einer Seitenführungsrolle eines der an den Seitenschildern vorgesehenen Paare von Seitenführungsrollen drehgelagert und mittels einer Torsionsfeder drehgefedert ist. Vorteilhafterweise kann für die Anlenkung des Schwenkhebels, der Seitenführungsrolle und der Torsionsfeder eine einzige Achse vorgesehen werden, ohne also einen größeren Aufwand zu erfordern.According to further features, it is proposed that the pivot lever with a fork end on an axis of a side guide roller of one of the pairs of side guide rollers provided on the side plates is rotatably supported and torsionally sprung by means of a torsion spring. Advantageously, a single axis can be provided for the articulation of the pivot lever, the side guide roller and the torsion spring, without requiring a greater outlay.

In Ausgestaltung der Erfindung ist vorgesehen, daß an dem Schwenkhebel der Kurvenfahreinrichtung mittig zwischen einer Seitenführungsrolle und der Zusatz-Seitenführungsrolle ein Paar Kippführungsrollen angeordnet ist. Durch die mittige Anordnung wird erreicht, daß die Laufrichtung der Fahrbahntangente entspricht und kein Schroten auftritt.In an embodiment of the invention it is provided that a pair of tilting guide rollers is arranged on the pivot lever of the cornering device between a side guide roller and the additional side guide roller. The central arrangement ensures that the direction of travel corresponds to the road tangent and that no crushing occurs.

Als Weiterentwicklung ist vorgesehen, daß zumindest eine Kippführungsrolle auf unterschiedliche Einschienenflanschträger einstellbar ist. Damit kann auf unterschiedliche Abmessungen Rücksicht genommen werden.As a further development, it is provided that at least one tilting guide roller can be set on different monorail flange supports. This means that different dimensions can be taken into account.

Eine weitere Verbesserung der Erfindung besteht darin, daß die an den Seitenschildern angeordneten Seitenführungsrollen den gleichen Durchmesser aufweisen wie die am Schwenkhebel der Kurvenfahreinrichtung angeordnete Zusatz-Seitenführungsrolle. Damit wird gewährleistet, daß die Laufrichtung der Rollen parallel zum Träger verläuft.Another improvement of the invention is that the side guide rollers arranged on the side plates have the same diameter as the additional side guide roller arranged on the pivoting lever of the cornering device. This ensures that the running direction of the rollers runs parallel to the carrier.

Eine weitere Ausgestaltung besteht ferner darin, daß zwischen den an den Seitenschildern angeordneten Paaren von Seitenführungsrollen jeweils nur ein Laufrad vorgesehen ist.Another embodiment also consists in that only one impeller is provided between the pairs of side guide rollers arranged on the side plates.

Das Fahrwerk für Hebezeuge, wie z.B. Einschienenbahn-Unterflanschfahrwerke, läuft auf einem Einschienenflanschträger 1 (vgl. Fig. 4) mit Höhen- und/oder Seitenkurven-Abschnitten 2. Das Fahrwerk wird durch ein Seitenschild 3a und ein verbundenes Seitenschild 3b getragen. An den Seitenschildern 3a und 3b sind Laufräder 4a, 4b und Seitenführungsrollen 5a, 5b bzw. 6a, 6b drehgelagert. Das Fahrwerk wird über einen Fahrantrieb 7, der z.B. aus einem Reibradantrieb besteht, angetrieben. Eine besondere Kurvenfahreinrichtung 8 (vgl. Fig. 2) ist mittels Feder 9 ständig an den Einschienenflanschträger 1 anstellbar und folgt dem jeweiligen Kurvenverlauf.The undercarriage for hoists, such as monorail underfloor trolleys, runs on a monorail flange support 1 (see FIG. 4) with height and / or side curve sections 2. The undercarriage is supported by a side plate 3a and a connected side plate 3b. On the side plates 3a and 3b are impellers 4a, 4b and Lateral guide rollers 5a, 5b and 6a, 6b pivoted. The undercarriage is driven by a travel drive 7, which consists, for example, of a friction wheel drive. A special curve driving device 8 (cf. FIG. 2) can be continuously adjusted to the monorail flange support 1 by means of spring 9 and follows the respective course of the curve.

Die Kurvenfahreinrichtung 8 wird an z.B. nur einem Seitenschild 3a (oder 3b) als drehgelagerter, gefederter einarmiger Schwenkhebel 10 ausgeführt.The cornering device 8 is e.g. only a side plate 3a (or 3b) designed as a pivoted, spring-loaded, single-arm pivot lever 10.

An dem freien Schwenkhebel-Ende 10a, das als Gabelende 10b ausgebildet ist, ist eine Zusatz-Seitenführungsrolle 11 drehgelagert, die dem Verlauf der Seitenfläche des Einschienenflanschträgers 1 folgt.On the free swivel lever end 10a, which is designed as a fork end 10b, an additional side guide roller 11 is rotatably mounted, which follows the course of the side surface of the monorail flange carrier 1.

Der Schwenkhebel 10 ist hierzu mit einem Gabelende 10b auf einer Achse 12 einer Seitenführungsrolle 6a, 6b eines der an den Seitenschildern 3a, 3b vorgesehenen Paare von Seitenführungsrollen drehgelagert und mittels einer Torsionsfeder 9a gefedert. Die Torsionsfeder 9a besitzt Federschenkel 9b, die sich am Schwenkhebel 10 und am Seitenschild 3a abstützen.For this purpose, the pivot lever 10 is rotatably supported with a fork end 10b on an axis 12 of a side guide roller 6a, 6b of one of the pairs of side guide rollers provided on the side plates 3a, 3b and is sprung by means of a torsion spring 9a. The torsion spring 9a has spring legs 9b which are supported on the pivot lever 10 and on the side plate 3a.

Weiterhin ist an dem Schwenkhebel 10 der Kurvenfahreinrichtung 8 mittig zwischen einer Seitenführungsrolle 6a und der Zusatz-Seitenführungsrolle 11 ein Paar Kippführungsrollen 13a, 13b drehgelagert. Eine der beiden Kippführungsrollen 13a (13b) ist mit ihrer Achse 23 in einem Langloch 24 auf die Abmessungen des Einschienenflanschträgers 1 einstellbar.Furthermore, a pair of tilting guide rollers 13a, 13b is rotatably mounted on the pivot lever 10 of the cornering device 8 centrally between a side guide roller 6a and the additional side guide roller 11. One of the two tilting guide rollers 13a (13b) can be adjusted with its axis 23 in an elongated hole 24 to the dimensions of the monorail flange carrier 1.

Die an den Seitenschildern 3a,3b drehgelagerten Seitenführungsrollen 5a,5b;6a,6b weisen den gleichen Durchmesser auf wie die am Schwenkhebel 10 der Kurvenfahreinrichtung 8 angeordnete Zusatz-Seitenführungsrolle 11. Zwischen den an den Seitenschildern 3a,3b vorgesehenen Paaren von Seitenführungsrollen 5a,5b; 6a,6b ist jeweils nur ein Laufrad 4a bzw. 4b drehgelagert.The side guide rollers 5a, 5b; 6a, 6b rotatably mounted on the side plates 3a, 3b have the same diameter as the additional side guide roller 11 arranged on the pivoting lever 10 of the cornering device 8. Between the pairs of provided on the side plates 3a, 3b Side guide rollers 5a, 5b; 6a, 6b, only one impeller 4a or 4b is rotatably supported.

Die beiden Seitenschilder 3a,3b sind wie üblich mittels Zwischenträgern 14a,14b verbunden, wobei durch Einstellschrauben 15a,15b und Einstellmuttern 16a,16b die jeweilige Breite des Einschienenflanschträgers 1 berücksichtigt werden kann. Eine Breitenänderung kann durch Entnehmen von Abstandsscheiben 18 bzw. durch zusätzliches Einlegen vorgenommen werden. Für die Laufräder 4a,4b sind Lagerzapfen 17 in den aus Blech hergestellten Seitenschildern 3a,3b befestigt. Der Zwischenträger 14a (14b) und die Einstellschraube 15a (15b) können einstückig ausgeführt sein - wie gezeichnet.As usual, the two side plates 3a, 3b are connected by means of intermediate supports 14a, 14b, the respective width of the monorail flange support 1 being able to be taken into account by means of adjusting screws 15a, 15b and adjusting nuts 16a, 16b. A change in width can be made by removing spacers 18 or by additional insertion. For the impellers 4a, 4b, bearing journals 17 are fastened in the side plates 3a, 3b made of sheet metal. The intermediate carrier 14a (14b) and the adjusting screw 15a (15b) can be made in one piece - as shown.

Wie Fig. 4 zeigt, liegt eine Laufrichtung 19 für die Kippführungsrollen 13a,13b parallel zu einer Tangente 21 an den Verlauf des Einschienenflanschträgers 1, so daß zwischen der Laufrichtung 19 und der Tangente 21 eine Parallelität 20 gewährleistet ist. Diese Parallelität 20 sichert daher einen gewünschten Lauf der Kippführungsrollen 13a,13b. Den Lagerzapfen 17 sind ferner Zusatz-Lagerzapfen 22a und 22b zugeordnet, auf denen noch weitere Laufrollen angeordnet werden können, falls eine andere Laufrollen-Anordnung wünschenswert ist.As shown in FIG. 4, a running direction 19 for the tilting guide rollers 13a, 13b lies parallel to a tangent 21 to the course of the monorail flange carrier 1, so that a parallelism 20 is ensured between the running direction 19 and the tangent 21. This parallelism 20 therefore ensures a desired run of the tilt guide rollers 13a, 13b. Additional bearing journals 22a and 22b are also associated with the bearing journals 17, on which additional rollers can be arranged if a different arrangement of the rollers is desirable.
