Description
Die Erfindung betrifft ein Fahrwerk einer schienenverfahrbaren Hebevorrichtung gemäß
dem Oberbegriff des Anspruches 1.The invention relates to a chassis of a rail-traveling lifting device according to
the preamble of
Ein derartiges Fahrwerk ist in der DE 1288269 beschrieben.Such a chassis is described in DE 1288269.
Es ist allgemein bekannt, bei der Überführung behinderter oder kranker Personen
Deckenlifte einzusetzen, die den Boden frei halten und nicht im Wege sind. Diese werden
an im Bereich der Decke angebrachten beispielsweise hohlprofilförmigen Schienen geführt.
Das Verfahren des Deckenliftes längs der Schiene erfolgt mittels eines Fahrwerks, das eine
Antriebseinheit und eine Trageinheit aufweist, die durch eine Gelenkstange miteinander
verbunden sind. Die Antriebseinheit verfügt über auf Laufflächen der Fahrschiene
abrollbare Laufräder, die sich an der Schiene abstützen und an einem gemeinsamen
Träger drehgelagert sind. Als Antriebselement ist ein Motor vorgesehen, dessen
Antriebskräfte über ein an einer Reibfläche der Schiene anliegendes Reibrad auf das
Fahrwerk übertragen werden. Die Laufflächen und die Reibfläche sind meist parallel
zueinander angeordnet.
Die Trageinheit verfügt ebenfalls über ein Fahrwerk mit Laufrädem, die wie die Laufräder
der Antriebseinheit auf den Laufflächen der Schiene abrollen. Sie sind ebenfalls an einem
gemeinsamen Träger drehgelagert. Der Träger ist unterhalb der Schiene mit der
Hebevorrichtung verbunden.It is generally known to use ceiling lifts in the transfer of disabled or sick persons, which keep the ground clear and are not in the way. These are guided on, for example, hollow-profile rails attached in the area of the ceiling. The ceiling lift is moved along the rail by means of a trolley which has a drive unit and a support unit which are connected to one another by an articulated rod. The drive unit has wheels that can be rolled on the running surfaces of the running rail, which are supported on the rail and are rotatably mounted on a common carrier. A motor is provided as the drive element, the drive forces of which are transmitted to the chassis via a friction wheel abutting a friction surface of the rail. The tread and the friction surface are usually arranged parallel to each other.
The support unit also has a running gear with wheels that roll on the running surfaces of the rail like the wheels of the drive unit. They are also pivoted on a common carrier. The carrier is connected to the lifting device below the rail.
Bei derartigen Fahrwerken für Deckenlifter liegt das Reibrad kraftbeaufschlagt an der Reibfläche. Die Anpreßkraft ist dabei so zu wählen, daß auch bei maximaler Last einwandfreie Antriebseigenschaften gewährleistet sind. So darf das Reibrad auch bei maximaler Belastung nicht durchdrehen. Bei einem derartigen Fahrwerk kann das Reibrad einem hohen Verschleiß unterliegen. Weiter erfährt das elastische Reibrad durch das kraftbeaufschlagte Anliegen an der Reibfläche bei längerer Nichtbenutzung des Deckenlifters eine Deformation, die bei Wiederinbetriebnahme des Liftes zunächst mit einem ungleichmäßigen Lauf verbunden sein kann. Ferner ist das Fahrwerk aufgrund der Federbeaufschlagung oft nur schwer von Hand verschiebbar. In such undercarriages for ceiling lifts, the friction wheel is pressurized on the Friction surface. The contact pressure is to be chosen so that even at maximum load impeccable drive properties are guaranteed. So the friction wheel can also Do not turn the maximum load. With such a chassis, the friction wheel subject to high wear. The elastic friction wheel experiences further through the Force-applied concerns on the friction surface if the Ceiling lift a deformation that initially occurs when the lift is restarted may be associated with an uneven run. Furthermore, the chassis is due to the Spring loading is often difficult to move by hand.
Aus der DE 26 18 516 C2 ist eine Laufkatze einer schienenverfahrbaren Hebevorrichtung bekannt, das ein Laufrad aufweist, welches als Trag- und Antriebsrad dient. Das Laufrad rollt auf einer sich in Längsrichtung einer Fahrschiene erstreckenden Lauffläche ab, die als Reibfläche des Laufrades dient. Als weiteres Laufrad ist ein Zusatzrad vorgesehen, das in Fahrtrichtung gesehen mit Abstand zum angetriebenen Laufrad an einem Hebelende eines schwenkbaren Hebels drehbar gelagert ist. Dieses Zusatzrad rollt im Betriebszustand der Laufkatze nicht auf der Lauffläche der Schiene ab; es befindet sich bei Normalbetrieb in einer Parkposition. Erst bei Ausfall oder bei Störungen am Antrieb wird das Stützrad durch Betätigung des Hebels auf die Lauffläche aufgesetzt, indem das freie Hebelende des als Doppelhebel ausgebildeten Hebels vertikal nach unten gezogen wird. Der Hebel wird hierzu soweit nach unten gezogen, daß das Zusatzrad seine Arbeitsposition einnimmt, wobei die Achse des Zusatzrades von der senkrechten unterhalb der Schwingachse zum Laufrad hin versetzt ist. In der Arbeitsposition des Zusatzrades wirkt dieses mit einem Stützrad, das in Fahrtrichtung gesehen dem Laufrad gegenüberliegt, derart zusammen, daß das Zusatzrad und das Stützrad auf der Lauffläche der Schiene abrollen, während das angetriebene Laufrad von der Lauffläche abgehoben ist. Auf diese Art und Weise wird es ermöglicht, die Laufkatze auch bei Ausfall des Antriebes zu verfahren.DE 26 18 516 C2 is a trolley of a lifting device that can be moved by rail known, which has an impeller, which serves as a supporting and drive wheel. The impeller rolls on a tread extending in the longitudinal direction of a running track, which as The friction surface of the impeller is used. An additional wheel is provided as a further impeller Driving direction seen at a distance from the driven impeller at one end of a lever pivotable lever is rotatably mounted. This additional wheel rolls in the operating state of the Trolley not on the tread of the rail; it is in normal operation a parking position. The jockey wheel is only activated in the event of failure or malfunctions in the drive Actuation of the lever placed on the tread by the free end of the lever as Double lever trained lever is pulled down vertically. The lever becomes this pulled down so far that the auxiliary wheel assumes its working position, the Axis of the auxiliary wheel from the vertical below the swing axis to the impeller is offset. In the working position of the auxiliary wheel, this works with a support wheel that is in Seen in the direction of travel opposite the impeller, together such that the additional wheel and roll the jockey wheel on the tread of the rail while the driven one Impeller is lifted off the tread. In this way it is possible to To move the trolley even if the drive fails.
Schließlich ist noch aus der US 1,367,522 ein Fahrwerk bekannt, das allerdings zum Antrieb kein an einer Lauffläche einer Fahrschiene kraftbeaufschlagt anliegendes Reibrad aufweist. Der Antrieb erfolgt hierbei über ein Zahnrad, welches beispielsweise in eine Zahnstange der Schiene eingreift. Der Antrieb über ineinandergreifende Zähne benötigt keine Anpreßkraft, wie das bei einem zum Antrieb des Fahrwerks an einer Reibfläche anliegenden Reibrad der Fall ist.Finally, a chassis is known from US 1,367,522, which, however, for Drive does not have a friction wheel applied to a running surface of a running rail having. The drive takes place via a gear, which, for example, in a Rack of the rail engages. The drive via interlocking teeth is required no contact pressure, like that for driving the undercarriage on a friction surface adjacent friction wheel is the case.
Die Aufgabe der Erfindung ist es, ein Fahrwerk der im Oberbegriff des Anspruchs 1
genannten Art so auszubilden, daß das Reibrad einem geringen Verschleiß unterliegt und
trotz Wartungsfreundlichkeit auch bei maximaler Last einen gleichmäßigen Antrieb
gewährleistet.The object of the invention is a chassis in the preamble of
Die Lösung dieser Aufgabe ergibt sich lösungsgemäß durch die in dem Patentanspruch 1
angegebenen Merkmale.
Durch die kennzeichnenden Merkmale der Unteransprüche 2 bis 9 ist das Fahrwerk in
vorteilhafter Weise weiter ausgestaltet. This object is achieved according to the solution by the features specified in
Due to the characterizing features of
Die Lösung sieht u.a. vor, daß daß der Hebel ein Doppelarmhebel ist, an dem auf einer
Seite das Reibrad gelagert ist und von dem auf der anderen Seite die Hebevorrichtung
gestützt ist.
Ein derartig ausgebildetes Fahrwerk stellt sicher, daß das Reibrad lastabhängig an die
Reibfläche der Fahrschiene angepreßt ist. Bei einer großen Last wird das Reibrad also mit
einer großen Kraft kraftbeaufschlagt, ist keine Last vorhanden, so erfolgt die
Kraftbeaufschlagung des Reibrades nur durch die Eigengewichtskraft der Hebevorrichtung.
Diese ist üblicherweise gering. Eine Verformung des Reibrades insbesondere bei längerer
Nichtbenutzung wird bei dem erfindungsgemäßen Fahrwerk vermieden.The solution provides, inter alia, that the lever is a double-arm lever on which the friction wheel is mounted on one side and from which the lifting device is supported on the other side.
Such a chassis ensures that the friction wheel is pressed depending on the load on the friction surface of the rail. In the case of a large load, the friction wheel is thus subjected to a large force; if there is no load, the friction wheel is only loaded by the weight of the lifting device. This is usually low. A deformation of the friction wheel, especially when not used for a long time, is avoided in the chassis according to the invention.
Eine leichte Konstruktion eines Deckenlifters wird dadurch erzielt, daß die Fahrschiene einen nach unten offene hohlprofilförmige Schiene mit im Innern angeordneten Laufflächen ist.A light construction of a ceiling lift is achieved in that the running rail a downwardly open hollow profile-shaped rail with treads arranged inside is.
Eine stabile Konstruktion des Deckenlifters ergibt sich, wenn eine T-förmige oder doppel-T-Schiene als Fahrschiene verwendet wird, an deren einem Flansch die Lauffläche und die Reibfläche ausgebildet sind.A stable construction of the ceiling lifter results when a T-shaped or double-T rail is used as a rail, on one flange of the tread and Friction surface are formed.
Zweckmäßigerweise sind das Reibrad und die Hebevorrichtung am Doppelhebel fliegend gelagert. Dies ermöglicht aufgrund der guten Zugänglichkeit der Bauteile eine einfache Reparatur und einen einfachen Austausch verschlissener Bauteile.The friction wheel and the lifting device on the double lever are expediently flying stored. Due to the good accessibility of the components, this enables simple Repair and easy replacement of worn components.
Um ein leichtes manuelles Verschieben des Fahrwerks zu erreichen, wird vorgeschlagen, daß der Doppelhebel unterhalb der Schwenkachse ein im wesentlichen horizontales Langloch aufweist, das sich zu beiden Seiten einer gedanklich durch die Schwenkachse gelegten vertikalen Ebene erstreckt.In order to achieve easy manual displacement of the undercarriage, it is proposed that that the double lever below the pivot axis is essentially horizontal Has elongated hole, which is on both sides of one mentally through the pivot axis laid vertical plane extends.
Vorteilhafterweise ist das Langloch zur Schwenkachse hin konvex ausgebildet, so daß keine nachträgliche, selbsttätige Verschiebung der Hebevorrichtung zur anderen Seite hin erfolgt.The elongated hole is advantageously convex toward the pivot axis, so that no subsequent, automatic displacement of the lifting device to the other side he follows.
Um beim Transport von Personen eine hohe Flexibilität zu erreichen, ist der Doppelhebel in seiner Mitte über ein Gelenk nach kardanischer Art mit dem Träger verbunden. Dadurch ist sichergestellt, daß bei einem Pendeln der Last in Fahrtrichtung sich der Hebelarm des Trägers und damit die relative Anpreßkraft des Reibrades sich nur geringfügig ändert und außerdem ein gefahrloses einfaches seitliches Schwenken der Hebevorrichtung möglich ist. In order to achieve a high degree of flexibility when transporting people, the double lever is in its middle connected to the girder via a gimbal-like joint. This is ensures that when the load swings in the direction of travel the lever arm of the Carrier and thus the relative contact pressure of the friction wheel changes only slightly in addition, a safe, simple lateral pivoting of the lifting device is possible.
Es wird vorgeschlagen, daß die Hebevorrichtung um eine vertikale Achse drehbar gelagert ist, so daß die zu transportierende Person in die jeweils günstigste Position gedreht werden kann.It is proposed that the lifting device be rotatably supported about a vertical axis is so that the person to be transported is turned into the most favorable position can.

Fig. 1 zeigt ein Fahrwerk 1 einer auf einer Fahrschiene 2 verfahrbaren Hebevorrichtung 3.
Das Fahrwerk 1 weist in Schienenlängsrichtung gesehen hintereinanderliegende Laufräder
4 auf, die paarweise nebeneinander angeordnet sind. Die Laufräder 4 sind über einen
gemeinsamen Träger 5 miteinander verbunden und an diesem frei drehbar gelagert. Auf
sich in Längsrichtung der Fahrschiene 2 erstreckenden und im wesentlichen horizontalen
Laufflächen 6 stützen sich die Laufräder 4 abrollbar ab.1 shows a
Der Träger 5 erstreckt sich zwischen den Laufrädern 4 teilweise bis unterhalb der
Fahrschiene 2 und ist über einen schwenkbaren, am Träger 5 abgestützten Doppelhebel 7
mit einem Reibrad 8 verbunden. Das Reibrad 8 ist an einem freien Ende des Doppelhebels
7 fliegend drehbar gelagert und durch einen Motor 9 (s. Fig. 3) antreibbar. An dem anderen
Ende des Doppelhebels 7 ist die Hebevorrichtung 3 fliegend schwenkbar befestigt.The
Durch das an einem Ende des Doppelhebels 7 angreifende Eigengewicht der
Hubvorrichtung 3 wird das Reibrad 8 bereits im lastfreien Zustand gegen eine Reibfläche 10
der Fahrschiene 2 gedrückt. Die Anpreßkraft entgegen wirkt nur das Eigengewicht des
Reibrades 8 und des antreibenden Motors 9. Sie hängt von den gewählten
Hebelverhältnissen des Doppelhebels 7 ab und kann über die Wahl des Aufhängepunktes
so eingestellt werden, daß das Reibrad 8 im lastfreien Zustand jeweils unter leichtem Druck
an der Reibfläche 10 anliegt. Im belasteten Zustand ist die Anpreßkraft der Last jeweils
proportional. Due to the dead weight acting on one end of the
Wie Fig. 1 weiter erkennen läßt, ist ein Paar von Laufrädem 4 dem Reibrad 8
gegenüberliegend angeordnet. Hierdurch wird eine Querwanderung des Reibrades in der

gedanklich gelegten vertikalen Ebene erstreckt. Das Langloch 12 ist
zur Schwenkachse hin konvex ausgebildet. Hierdurch läßt sich die Hebevorrichtung 3
jeweils von der einen Seite der vertikalen Ebene (von der einen Seite des Drehpunktes der
Schwenkachse) zur anderen Seite verschieben. Befinden sich die Hebevorrichtung 3 und
das Reibrad 8 auf derselben Seite, ist das Reibrad 8 entlastet und ein besonders leichtes
