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-shaped rail of a suspension crane, according to 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 Trägern 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 beams by means of 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 monorail 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 transformed; 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 hanging 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.As a result, 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 occur destroy or destroy the overhead conveyor and the ceiling structure can damage, because in addition to the forces exerted by the suspension system be well received, 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 given by the in the Claim 1 specified features. Due to the characteristic features of claims 2 to 7 is the device for hanging a rail in advantageously refined.

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 Metallträgern 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 attached tension element before that between the structure and the tension element Rubber-metal element with two spaced apart essentially horizontal metal supports 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 flow of force 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 lies 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 related to the elastic rubber ensure that horizontal force peaks that occur in pulses are absorbed, d. H. be dampened. You will be in dampened vibrations with very low amplitude converted.

Eine innige Verbindung zwischen dem Gummi und den Metallträgern 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 that lies against 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 Stirnfläche 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 carrier 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 Querträgern 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 Traction element 2 via a rubber-metal element 3 on a as a T-beam 4a trained structure 4 attached. For fastening the rubber-metal element 3 on the T-beam 4a is a U-shaped cross member 5, which with its upper edges 5a abuts the lower outer surface 6 of the T-beam 4a. The firm connection between the flange 6a and the cross member 5 is made via tabs 7, the located on both sides of the web 8 on the inside of the flange 6a and on the cross beam 5 extending beyond the flange width. The Tabs 7 and the cross member 5 are each by means of a screw 9, which by Appropriate holes in the ceiling bracket 7 and in the cross member 5 inserted is firmly screwed together. The same time on the inside of the flange 6a The overlying tab 7 causes the flange 6a and the cross member 5 to be fixed are interconnected. Fig. 3 shows in a simplified plan view that for each suspension seen in the longitudinal direction of the T-beam 4 two cross beams 5th are arranged parallel and spaced apart so that the screws 9 Corner points of an imaginary square (rectangle is of course also possible) form. In the center of the square there is a tension element 2 in the case of two cross beams 5 attached.

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 In the longitudinal direction of the T-beam, vertically below the web, the cross beams 5 are fixed connected to the rubber-metal element 3.

Das Gummi-Metall-Element 3 besteht aus zwei voneinander beabstandeten im wesentlichen horizontalen Metallträgern 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 Metallträgern 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 3.The rubber-metal element 3 consists of two spaced apart essential horizontal metal beams 11a, 11b, which are designed as metal plates are. 3 shows in particular that the metal carrier 11a has a circular disc central opening 12 is. The central opening 12 is vertically spaced above one central opening 13 of the lower metal carrier 11b arranged. Seen from above the lower metal beam 11b extends in opposite directions across the Outside contour of the metal carrier 11a also. Between the metal supports is another mutually facing inner surfaces and a rubber plate 14 arranged attached. The attachment is done in the embodiment by vulcanizing the Rubbers on the metal supports 11a, 11b. Of course, it can Rubber can also be any other elastic material that is not must be vulcanized. It is equally conceivable that the elastic Material is glued to the inner surfaces of the metal carrier 11a 11b. That too Rubber is plate-shaped, is only a special embodiment of the rubber-metal element 3rd

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 rubber plate 14 also has an opening aligned with the openings 13, 14, so that the tension element 2 through the thus formed, in the vertical direction extending total opening can be pushed through.

Der untere Metallträger 11b ist mittels Schrauben 10 und Abstandselementen 15 an den Querträgern 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 11 a mit seiner Stirnfläche 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 lower metal support 11b is attached by means of screws 10 and spacer elements 15 the cross members 5 screwed and thus via the cross member 5 with the structure 4th firmly connected. The tension element 2 is at one end 2a with an external thread 2b provided with this end 2a through the openings 12 and 13 and attached to the upper metal support 11a. The attachment takes place here by means of a Nut 16, which is screwed onto the end 2a and also at the top Metal support 11a is soldered or welded. The latter is not essential required, but makes handling easier. As can be seen in FIGS. 1 and 2 additionally provided as a hollow cylinder spacer 17 by which is inserted through the end 2a of the tension element 2 and which at the Inner surface of the upper metal support 11 a rests with its end face. By means of a second nut 18 is the spacer against the upper metal support 11a pressed, i.e. axially clamped. This results in a rigid connection between the tension element 2 and the upper metal support 11a. The other End of the tension element 2, the rail 1 is articulated in a known manner.

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 11 b 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 directed tensile and compressive forces through the rubber-metal element 3 as in a rigid connection transferred to the structure. Especially pulse-like horizontal force peaks, for example due to impacts, cause the upper metal support 11a compared to the lower metal support 11b due to the move elastic effect of the rubber 14 against each other. This elastic Deformation of the rubber 14 intercepts the pulse peaks. The rubber-metal element 3 acts as a quasi-rigid intermediate element, which essentially only horizontal forces shows its elastic properties.
