Description
Die Erfindung betrifft eine Vorrichtung zum Aufhängen einer Schiene, insbesondere einer nach unten offenen hohlprofilförmigen Schiene eines Hängekrans, gemäß dem Anspruch 1.The invention relates to a device for hanging a rail, in particular a downwardly open hollow-profile rail of a suspension crane, according to the Claim 1.
Aus dem Prospekt "Kranbaukasten KBK" der Mannesmann Demag Fördertechnik AG ist eine nach unten offene hohlprofilförmige Schiene einer Hängebahn bekannt, in deren Längsrichtung eine Hebevorrichtung mittels Fahrwerkschienen verfahrbar ist. Die Schiene ist dabei pendelnd, d. h. verschwenkbar, an einem Tragwerk oder einem Querträger mittels vertikal angeordneten länglichen Trägem oder Zugelementen aufgehängt, wobei jeweils die unteren Enden der Träger an der Schiene und die oberen Enden an dem Tragwerk oder dem Querträger befestigt sind. Die pendelnde Aufhängung stellt sicher, daß sich die Hängebahn selbsttätig in den Gleichgewichtszustand bringt; dies ist der Zustand, bei dem keine horizontalen Kräfte mehr wirksam sind, alle Kräfte sind vertikal nach unten gerichtet. Die pendelnde Aufhängung wird dadurch sichergestellt, daß die Träger an den Enden mit Kugelköpfen versehen und in dazu komplementäre Kugelpfannen an der Schiene bzw. am Tragwerk eingehängt sind. Bei der pendelnden Aufhängung werden insbesondere stoßartige Belastungen der Schienen in Schwingungsenergie umgewandelt; die Schienen begeben sich in Form von gedämpften Schwingungen wieder in ihre Ausgangslage zurück.From the brochure "KBK crane construction kit" from Mannesmann Demag Fördertechnik AG is a downwardly open hollow profile rail of a monorail known in the longitudinal direction of which a lifting device can be moved by means of chassis rails. The rail is swinging, i. H. pivotable, on a structure or a Cross beam using vertically arranged elongated beams or tension elements suspended, with the lower ends of the carrier on the rail and the upper ends are attached to the structure or the cross member. The commuting Suspension ensures that the overhead conveyor moves automatically into the Brings equilibrium; this is the state where there are no horizontal forces are more effective, all forces are directed vertically downwards. The commuting Suspension is ensured by the straps at the ends Ball heads and complementary ball sockets on the rail or are attached to the structure. With the pendulum suspension in particular shock loads on the rails in vibration energy converted; the rails take the form of damped vibrations back to their starting position.
Für einen Hängekran, insbesondere mit einem seitlich herausragenden Ausleger, ist die oben beschriebene pendelnde Aufhängung nicht geeignet, da die nach oben gerichteten vertikalen Kräfte nicht aufgenommen werden. For a suspended crane, especially with a jib protruding from the side the swinging suspension described above is not suitable as the upward directed vertical forces are not absorbed.
Folglich kommt als alternative Lösung bei einem derartigen Hängekran nur eine starre Aufhängung der Schienen in Frage. Diese hat allerdings den Nachteil, daß bei Stößen auftretende lmpulsspitzen die Hängebahn und die Deckenkonstruktion zerstören oder beschädigen können, da bei diesen neben den Kräften, welche vom Aufhängesystem gut aufgenommen werden, auch kurzfristig horizontale Kräfte mit sehr großer Amplitude auftreten. Horizontale Kräfte treten aber auch während des normalen Betriebs des Hängekrans auf, und zwar aufgrund der Durchbiegung der Schienen zwischen den einzelnen Aufhängungepunkten. Diese horizontalen Kräfte während des Normalbetriebes stellen ebenfalls eine starke Belastung der Hängebahn dar, welche sich im Laufe der Zeit in einem erhöhten Verschleiß bemerkbar macht.Consequently, only a rigid solution comes as an alternative solution for such a suspended crane Suspension of the rails in question. However, this has the disadvantage that with bumps Pulse peaks that appear destroy or destroy the overhead conveyor and the ceiling structure can damage, because in addition to the forces exerted by the suspension system well absorbed, even in the short term horizontal forces with very large Amplitude occur. However, horizontal forces also occur during normal Operation of the overhead crane due to the deflection of the rails between the individual suspension points. These horizontal forces during normal operation also places a heavy load on the overhead conveyor, which manifests itself in increased wear over time.
Die Aufgabe der Erfindung ist es, eine starre Aufhängung einer Schiene zu schaffen, bei der horizontale Kräfte, insbesondere impulsartige, stark gedämpft werden.The object of the invention is to provide a rigid suspension of a rail, in which horizontal forces, especially impulses, are strongly damped.
Die Lösung dieser Aufgabe ist erfindungsgemäß angegeben durch die in dem
Patentanspruch 1 angegebenen Merkmale. Durch die kennzeichnenden Merkmale
der Unteransprüche 2 bis 7 ist die Vorrichtung zum Aufhängen einer Schiene in
vorteilhafterweise weiterausgestaltet.The solution to this problem is specified by the in the
Claim 1 specified features. Due to the characteristic features
of
Die Erfindung sieht bei einer Vorrichtung zum Aufhängen einer Schiene an einem Tragwerk mit einem zwei Enden aufweisenden und mit einem Ende der Schiene befestigten Zugelement vor, daß zwischen dem Tragwerk und dem Zugelement ein Gummi-Metall-Element mit zwei voneinander beabstandeten im wesentlichen horizontalen Metallträgem vorgesehen ist, an deren aneinander zugewandten Innenflächen der Gummi befestigt ist, wobei das Tragwerk mit dem unteren Metallträger und das andere Ende des Zugelements mit dem oberen Metallträger fest verbunden ist. Der Kraftflluß geht über das Zugelement zum oberen Metallträger, der sich auf dem Gummi abstützt. Der als Zwischenschicht ausgebildete Gummi wiederum liegt auf dem unteren Metallträger auf, der an dem Tragwerk befestigt ist. Die innige Verbindung zwischen dem Gummi und der Innenfläche der Metallträger verhindert, daß sich die Metallträger frei gegeneinander verschieben können. The invention provides for a device for hanging a rail on a Structure with one end and one end of the rail fastened tension element before that between the structure and the tension element Rubber-metal element with two spaced apart essentially horizontal metal support is provided, on their facing each other Inner surfaces of the rubber is attached, the structure being with the lower Metal support and the other end of the tension element with the upper metal support connected is. The power flow goes through the tension element to the upper metal support, the is supported on the rubber. The rubber formed as an intermediate layer in turn rests on the lower metal support, which is attached to the structure. The intimate connection between the rubber and the inner surface of the metal carrier prevents the metal supports from moving freely against each other.
Gleichzeitig stellt diese Verbindung im Zusammenhang mit dem elastischen Gummi sicher, daß horizontale Kraftspitzen, die impulsartig auftreten, abgefangen, d. h. gedämpft werden. Sie werden auf diese Weise in gedämpfte Schwingungen mit sehr geringer Amplitude umgewandelt.At the same time, this connection is in connection with the elastic rubber ensure that horizontal force peaks that occur in a pulsed manner are intercepted, d. H. be dampened. You will be in dampened vibrations with very low amplitude converted.
Eine innige Verbindung zwischen dem Gummi und den Metallträgem wird dadurch erzielt, daß der Gummi an die Metallträger anvulkanisiert ist.This creates an intimate connection between the rubber and the metal supports achieved that the rubber is vulcanized to the metal carrier.
Ein kompaktes Gummi-Metall-Element mit gleichmäßiger Verteilung der Belastung wird durch eine Ausgestaltung erreicht, bei der das mit dem oberen Metallträger verbundene Ende des Zugelements unter Belassung eines Zwischenraumes durch eine vertikale Öffnung des Gummi-Metall-Elementes geführt ist.A compact rubber-metal element with even distribution of the load is achieved by an embodiment in which that with the upper metal support connected end of the tension element by leaving a space through a vertical opening of the rubber-metal element is guided.
Eine biegesteife Verbindung zwischen Zugelement und Metallträger erhält man durch Verwendung eines Abstandselements, das am oberen Metallträger anliegt und durch welches das Ende des Zugelementes geführt ist.A rigid connection between the tension element and the metal support is obtained by Use of a spacer, which rests on the upper metal support and through which is the end of the tension element.
Zweckmäßigerweise ist hierbei das Abstandselement zusätzlich an dem oberen Metallträger befestigt.The spacer element is expediently additionally on the upper one Metal bracket attached.
Bei einer einfachen Ausführungsform ist das Abstandselement ein vertikal angeordneter Hohlzylinder, dessen Stimfläche an dem oberen Metallträger befestigt ist.In a simple embodiment, the spacer is vertical arranged hollow cylinder, the end face attached to the upper metal support is.
Das mit dem oberen Metallträger festverbundene Ende des Zugelements ist im Bereich des unteren Metallträgers mit einem Außengewinde versehen, auf dem eine das Abstandselement gegen den oberen Metallträger pressende Mutter aufgeschraubt ist, um eine stabile und bei horizontalen Kräften nicht nachgiebige Verbindung zwischen Metallträger und Zugelement zu erreichen.The end of the tension element which is firmly connected to the upper metal support is in the Area of the lower metal support with an external thread on which one the spacer against the upper metal support nut is screwed on to a stable and non-compliant with horizontal forces To achieve connection between the metal support and tension element.

Fig. 1 und Fig. 2 zeigen eine Vorrichtung zum Aufhängen einer nach unten offenen
hohlprofilförmigen Schiene 1 z. B. für einen Hängekran. Die Schiene ist mittels eines
Zugelementes 2 über eine Gummi-Metall-Element 3 an einem als T-Träger 4a
ausgebildetem Tragwerk 4 befestigt. Zur Befestigung des Gummi-Metall-Elements 3
an dem T-Träger 4a dient ein U-förmiger Querträger 5, der mit seinen oberen Kanten
5a an der unteren Außenfläche 6 des T-Trägers 4a anliegt. Die feste Verbindung
zwischen dem Flansch 6a und dem Querträger 5 wird über Laschen 7 hergestellt, die
sich beidseitig des Stegs 8 jeweils auf der Innenseite des Flansches 6a und auf dem
sich über die Flanschbreite hinaus erstreckenden Querträger 5 abstützen. Die
Laschen 7 und der Querträger 5 sind jeweils mittels einer Schraube 9, welche durch
entsprechende Bohrungen in der Deckenlasche 7 und im Querträger 5 durchgesteckt
ist, fest miteinander verschraubt. Die gleichzeitig auf der Innenseite des Flansches 6a
aufliegende Lasche 7 bewirkt, daß dabei der Flansch 6a und der Querträger 5 fest
miteinander verbunden sind. Fig. 3 zeigt in einer vereinfachten Draufsicht, daß für
jede Aufhängung in Längsrichtung des T-Trägers 4 gesehen zwei Querträger 5
parallel und so beabstandet zueinander angeordnet sind, daß die Schrauben 9 die
Eckpunkte eines gedachten Quadrats (Rechteck ist selbstverständlich auch möglich)
bilden. Im Zentrum des Quadrats ist bei zwei Querträgem 5 ein Zugelement 2
befestigt.Fig. 1 and Fig. 2 show a device for hanging a downwardly open
hollow profile rail 1 z. B. for a suspended crane. The rail is by means of a
Der U-profilförmige Querschnitt der Querträger ist in Fig. 2 gut zu erkennen. In
Längsrichtung des T-Trägers vertikal unterhalb des Stegs sind die Querträger 5 fest
mit dem Gummi-Metall-Element 3 verbunden. The U-shaped cross section of the crossbeam can be clearly seen in FIG. 2. In

Das Gummi-Metall-Element 3 besteht aus zwei voneinander beabstandeten im
wesentlichen horizontalen Metallträgem 11a, 11b, die als Metallplatten ausgebildet
sind. Insbesondere Fig. 3 zeigt, daß der Metallträger 11a eine Kreisscheibe mit
zentraler Öffnung 12 ist. Die zentrale Öffnung 12 ist vertikal beabstandet über einer
zentralen Öffnung 13 des unteren Metallträgers 11b angeordnet. Von oben gesehen
erstreckt sich der untere Metallträger 11b in entgegengesetzten Richtungen über die
Außenkontur des Metallträgers 11a hinaus. Zwischen den Metallträgem ist an deren
einander zugewandten Innenflächen eine Gummiplatte 14 angeordnet und an diesen
befestigt. Die Befestigung erfolgt im Ausführungsbeispiel durch Anvulkanisieren des
Gummis an die Metallträger 11a, 11b. Selbstverständlich kann es sich bei dem
Gummi auch um ein beliebiges anderes elastisches Material handeln, das nicht
notwendig anvulkanisiert sein muß. Genauso gut ist es denkbar, daß das elastische
Material an die Innenflächen der Metallträger 11a 11b angeklebt ist. Auch das der
Gummi plattenförmig ausgebildet ist, ist nur eine spezielle Ausgestaltung des Gummi-Metall-Elements

Auch die Gummiplatte 14 weist eine zu den Öffnungen 13,14 fluchtende Öffnung auf,
so daß das Zugelement 2 durch die so gebildete, sich in vertikaler Richtung
erstreckende Gesamtöffnung durchsteckbar ist.The
Der untere Metallträger 11b ist mittels Schrauben 10 und Abstandselementen 15 an
den Querträgem 5 angeschraubt und damit über die Querträger 5 mit dem Tragwerk 4
fest verbunden. Das Zugelement 2 ist an einem Ende 2a mit einem Außengewinde 2b
versehen, mit diesem Ende 2a durch die Öffnungen 12 und 13 hindurchgesteckt und
an dem oberen Metallträger 11a befestigt. Die Befestigung erfolgt hier mittels einer
Mutter 16, die an das Ende 2a aufgeschraubt und außerdem an dem oberen
Metallträger 11a angelötet oder angeschweißt ist. Letzteres ist nicht unbedingt
erforderlich, erleichtert aber die Handhabung. Wie Fig. 1 und Fig. 2 entnehmbar ist, ist
zusätzlich ein als Hohlzylinder ausgebildetes Abstandselement 17 vorgesehen, durch
welches das Ende 2a des Zugelements 2 hindurchgesteckt ist und das an der
Innenfläche des oberen Metallträgers 11a mit seiner Stimfläche anliegt. Mittels einer
zweiten Mutter 18 ist das Abstandselement gegen den oberen Metallträger 11a
angepreßt, d.h. axial verspannt. Hierdurch ergibt sich eine biegesteife Verbindung
zwischen dem Zugelement 2 und dem oberen Metallträger 11a. An dem anderen
Ende des Zugelements 2 ist die Schiene 1 in bekannter Weise gelenkig befestigt.The
Während des Betriebs des Hängekrans werden die vertikal nach oben und unten
gerichteten Zug- und Druckkräfte durch das Gummi-Metall-Element 3 wie bei einer
starren Verbindung auf das Tragwerk übertragen. Insbesondere impulsartige
horizontale Kraftspitzen, beispielsweise aufgrund von Stößen, führen dazu, daß sich
der obere Metallträger 11a gegenüber dem unteren Metallträger 11b aufgrund der
elastischen Wirkung des Gummis 14 gegeneinander verschieben. Diese elastische
Deformation des Gummis 14 fängt hierbei die lmpulsspitzen ab. Das Gummi-Metall-Element
3 wirkt wie ein quasistarres Zwischenelement, das im wesentlichen nur bei
horizontalen Kräften seine elastischen Eigenschaften zeigt. During the operation of the overhead crane, they are vertically up and down
