Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum senkrechten Anheben einer Last, vorzugsweise um einen Kran oder ein anderes Hebezeug. Die Last wird mittels eines Seiles angehoben, wobei das Seil ein Synthetikseil ist.The invention relates to a device for lifting a load vertically, preferably around a crane or another hoist. The load is lifted by means of a rope, the rope being a synthetic rope.
Der Einsatz von Synthetikseilen ist bereits in zahlreichen Anwendungen bekannt. Je weiter die Entwicklung solcher Seile fortschreitet, desto breiter werden ihre Einsatzmöglichkeiten. Besonders das im Verhältnis zu Stahlseilen geringe Gewicht und die hohe Festigkeit machen Synthetikseile besonders geeignet für zum Beispiel Sicherungsseile beim Sport, medizinische Anwendungen und technische Textilprodukte. Im Sportbereich und in der Lebensrettung kommen Synthetikseile seit langem zum Einsatz. In jüngerer Zeit werden Synthetikseile aber auch für industrielle Zwecke eingesetzt, so zum Beispiel zum Vertäuen von Schiffen im Hafen, beim kommerziellen Fischfang, im Forstwesen und beim Verlegen von Kabeln. Insbesondere beim Verlegen von Unterwasserkabeln haben sich die Synthetikseile bewährt, dass sie auf der Wasseroberfläche schwimmen und so nicht in die Schiffsschraube gelangen können. Das geringe Eigengewicht des Synthetikseils reduziert vorteilhafter Weise das Transportgewicht an Board und das Einzugsgewicht beim Einholen. Synthetikseile haben den weiteren Vorteil, dass sie bei entsprechender Konditionierung resistenter gegen das aggressive Salzwasser sind, als herkömmliche Stahlseile.The use of synthetic ropes is already known in numerous applications. The further the development of such ropes progresses, the broader their application possibilities become. In particular, the low weight and high strength compared to steel ropes make synthetic ropes particularly suitable for sports safety ropes, medical applications and technical textile products. Synthetic ropes have been used for a long time in sports and in lifesaving. Recently, synthetic ropes have also been used for industrial purposes, such as mooring ships in the harbor, commercial fishing, forestry and cable laying. Especially when laying underwater cables, the synthetic ropes have proven to float on the water surface and so can not get into the propeller. The low weight of the synthetic rope advantageously reduces the transport weight on board and the pull-in weight when catching. Synthetic ropes have the added benefit of being more resistant to aggressive saltwater when properly conditioned than traditional steel ropes.
Es ist eine Aufgabe der Erfindung eine Vorrichtung zum senkrechten Anheben einer Last bereitzustellen.It is an object of the invention to provide a device for lifting a load vertically.
Diese Aufgabe wird erfüllt durch eine Vorrichtung nach Anspruch 1.This object is achieved by a device according to claim 1.
Bei der Vorrichtung der Erfindung handelt es sich um eine Vorrichtung zum senkrechten Anheben einer Last, vorzugsweise um einen Kran. Der Kran kann ein mobiler Kran sein, der beispielsweise auf einem Fahrzeug montiert ist oder ein bekannter Baustellenkran, der transportiert und aufgebaut werden kann. Die Vorrichtung kann aber auch an oder in einem Gebäude oder einem Gerüst fest montiert sein und zum Beispiel einen Lasten- oder Personenaufzug anheben und senken. Unter senkrechtem Anheben wird im Sinne der Erfindung ebenfalls ein lineares Ziehen parallel zu einer schiefen Ebene verstanden, zum Beispiel das Bewegen eines Skiliftes, einer Bergbahn oder eines Lastenliftes an einem Berghang.The device of the invention is a device for lifting a load vertically, preferably around a crane. The crane can be a mobile crane mounted on a vehicle, for example, or a well-known construction crane that can be transported and set up. However, the device can also be firmly mounted on or in a building or a scaffold and, for example, raise and lower a load or passenger lift. For the purposes of the invention, vertical lifting also means a linear pulling parallel to an inclined plane, for example the movement of a ski lift, a mountain railway or a load lift on a mountainside.
Die Vorrichtung weist eine Basis auf und einen Ausleger, der von der Basis abragt. Weiterhin weist die Vorrichtung ein Seil auf, das von der Basis über die Spitze des Auslegers geführt ist und eine Vorrichtung zum Fassen oder Befestigen einer Last, die an dem über die Spitze des Auslegers geführten Ende des Seils befestigt oder befestigbar ist. Bei dem Seil handelt es sich um ein Synthetikseil.The device has a base and a cantilever that protrudes from the base. Furthermore, the device comprises a cable, which is guided from the base over the tip of the boom and a device for grasping or securing a load which is fastened or attachable to the end of the cable guided over the tip of the boom. The rope is a synthetic rope.
Bevorzugt kann der Ausleger relativ zu der Basis bewegt werden. Dabei kann er im Verhältnis zur Basis nach oben oder unten verschwenken werden oder sich relativ zur Basis um eine im Wesentlichen senkrecht zur Basisgrundfläche gerichteten Rotationsachse drehen. Ebenso ist es möglich, dass sich die Basis gemeinsam mit dem Ausleger um eine gemeinsame Rotationsachse dreht. Der Ausleger kann teleskopierbar sein.Preferably, the boom can be moved relative to the base. In this case, it can be pivoted upwards or downwards in relation to the base or rotate relative to the base about an axis of rotation oriented substantially perpendicular to the base base surface. It is also possible that the base rotates together with the boom about a common axis of rotation. The boom can be telescopic.
Bevorzugt handelt es sich bei dem Synthetikseil um ein Seil aus HMPE oder HPPE Fasern. Die Erfindung ist aber nicht auf den Einsatz dieser speziellen Synthetikfasern beschränkt, sondern umfasst vielmehr die Verwendung auch weiterer Synthetikfasern, die gleiche oder ähnliche Eigenschaften haben, wie die genannte.Preferably, the synthetic rope is a rope of HMPE or HPPE fibers. However, the invention is not limited to the use of these special synthetic fibers, but rather includes the use of other synthetic fibers having the same or similar properties as those mentioned.
Aus der Gruppe der HMPE (High Modulus Polyethylene) Stoffe werden synthetische Fasern hergestellt, die im Wasser schwimmen können, exzellente Eigenschaften bezüglich der Abriebs-, Knick- und Zugfähigkeit aufweisen und eine der besten UV-Beständigkeiten unter den synthetischen Fasern haben. HPME Fasern haben eine chemische Struktur die der von normalem Polyethylen vergleichbar ist, aber ein weit höheres Molekulargewicht und eine weit höhere Kristallinität aufweist.The group of HMPE (High Modulus Polyethylene) fabrics is made up of synthetic fibers that can float in the water, have excellent abrasion, buckling and tensile properties and one of the best UV resistance among synthetic fibers. HPME fibers have one chemical structure comparable to that of normal polyethylene, but with a much higher molecular weight and a much higher crystallinity.
Das Seil kann eine Ummantelung aufweisen, wobei das Seil und die Ummantelung aus der gleichen Synthetikfaser bestehen können oder aber die Ummantelung aus einer anderen Synthetik- oder Kunststofffaser besteht als das Seil selbst. Die letzter Möglichkeit kann insbesondere dann gewählt werden, wenn die Ummantelung gewisse Eigenschaften wie Gleitfähigkeit, Abriebfestigkeit, Lichtbeständigkeit oder zum Beispiel eine fluoreszierende Oberfläche aufweisen soll, die mittels der das Seil bildenden Synthetikfaser nicht oder nur mit großem Aufwand erreicht werden kann.The rope may have a sheath, wherein the rope and the sheath may consist of the same synthetic fiber or the sheath of a different synthetic or plastic fiber than the rope itself. The last possibility may be chosen in particular when the sheath certain properties such as lubricity, abrasion resistance, light resistance or, for example, should have a fluorescent surface, which can not be achieved or only with great effort by means of the synthetic fiber forming the rope.
Es kann auch sinnvoll sein, dass die Ummantelung, egal ob sie aus dem gleichen oder einem anderen Material als das Seil besteht, eine andere Einfärbung aufweist. Dabei kann die Ummantelung selbst wiederum verschiedene Schichten unterschiedlicher Farbe aufweisen. Auf diese Weise kann zum Beispiel einfach durch Augenschein ein Abrieb an dem Seil festgestellt werden. Kommt unter der Ummantelung das Seil zum Vorschein oder ist eine bevorzugt signalfarbene Schicht der Ummantelung sichtbar, so kann dies ein Indiz dafür sein, dass das Seil gewechselt werden muss.It may also be useful that the sheath, whether it is made of the same or a different material than the rope, has a different coloration. In this case, the casing itself may in turn have different layers of different colors. In this way, for example, simply by inspection, abrasion on the rope can be detected. If the rope appears under the sheathing or if a preferably signal-colored layer of the sheathing is visible, this can be an indication that the rope has to be changed.
In das Seil selbst können zusätzliche Fasern aus einem anderen Material, zum Beispiel einem metallischen oder nichtmetallischem Werkstoff, eingeflochten oder eingewoben sein. Dabei kann es sich beispielsweise um Glasfasern, Kohlefasern oder Kupferfasern handeln, die gewisse Eigenschaften wie die Zug- oder Knickfestigkeit des Seils verbessern. Insbesondere metallische bzw. andere elektrisch leitende Fasern können auch dazu benutzt werden, die Unversehrtheit des Seils zu überprüfen. So kann solch eine Faser über die gesamte Länge des Seils reichen, mit einem Anfang und einem Ende die mit einem Messgerät verbindbar sind. Mittels der Messung kann dann zum Beispiel festgestellt werden, ob die stromleitende Faser unversehrt oder vielleicht gebrochen ist, wobei Letzteres ein Indiz für eine Überdehnung des Seils oder eine andere Beschädigung, zum Beispiel durch Knicken, sein kann, die es erforderlich macht, das Synthetikseil zu wechseln. Um zu verhindern, dass gefälschte Synthetikseile verwendet werden, können in das Seil fälschungssichere Kennungen eingewoben werden, die beispielsweise Angaben über den Hersteller, das Herstellungsdatum und ein Ablaufdatum umfassen, die mittels eines elektronischen Gerätes, ähnlich der Kennzeichnungen an Lebensmitteln und Kleidungsstücken, abgefragt oder abgelesen werden können. Bei der Kennung kann es sich aber auch um zum Beispiel Pigmentierungen handeln, die mittels spezieller Lampen oder Sichtgeräte erfasst werden können und für die Echtheit des Produktes stehen.Additional fibers of another material, for example a metallic or non-metallic material, may be woven or woven into the rope itself. These may be, for example, glass fibers, carbon fibers or copper fibers which improve certain properties, such as the tensile or kink resistance of the rope. In particular, metallic or other electrically conductive fibers can also be used to check the integrity of the rope. Thus, such a fiber can extend over the entire length of the rope, with a beginning and an end connectable to a measuring device. By means of the measurement it can then be determined, for example, whether the conductive fiber is intact or perhaps broken, the latter being an indication of overstretching of the rope or other damage, for example kinking, which makes it necessary to attach the synthetic rope switch. To prevent fake synthetic ropes from being used, tamper-resistant identifiers may be woven into the rope, including, for example, manufacturer information, date of manufacture and an expiration date interrogated or read by means of an electronic device similar to food and clothing markings can be. The identification can also be, for example, pigmentations which can be detected by means of special lamps or viewing devices and represent the authenticity of the product.
Die farbliche Gestaltung der Ummantelung und des Seils ohne Ummantelung können auch die Corporate Identity des Nutzers aufgreifen und zum Beispiel die Unternehmensfarben des Herstellers oder des Anwenders aufweisen.The color scheme of the sheathing and the rope without sheathing can also take up the corporate identity of the user and have, for example, the corporate colors of the manufacturer or the user.
Die Fasern die das Synthetikseil bilden oder mitbilden, können mit einem Coating oder einem Finishing überzogen sein, um die Haltbarkeit insbesondere der Synthetikfasern gegenüber Umwelteinflüssen, wie Kälte (Vereisung), Feuchte und Sonnenlicht zu verbessern.The fibers which form or co-form the synthetic rope may be coated or finished to improve the durability, in particular of the synthetic fibers, against environmental influences such as cold (icing), moisture and sunlight.
Bevorzugt ist es, wenn die Dichte des Synthetikseils gleich oder kleiner 1,5kg/dm3 ist, besonders bevorzugt ist die Dichte gleich oder kleiner 1kg/dm3. Dabei soll das Synthetikseil einen Durchmesser von maximal 80mm aufweisen, bevorzugt einen Durchmesser von maximal 30 mm bis 60 mm.It is preferable that the density of the synthetic rope is equal to or smaller than 1.5kg / dm 3 , more preferably, the density is equal to or smaller than 1kg / dm 3 . The synthetic rope should have a maximum diameter of 80 mm, preferably a maximum diameter of 30 mm to 60 mm.
Da das Synthetikseil zum Beispiel das Stahlseil in einem Kran ersetzen kann, ist es in solchen Fällen bevorzugt, wenn das Synthetikseil im Wesentlichen den gleichen Durchmesser aufweist, wie das Stahlseil, das es ersetzt. Dadurch können alle Leitrollen und anderen seilführenden Teile des Kranes unverändert bleiben, was den Ersatz der Stahlseile durch Synthetikseile wirtschaftlich interessant macht, da keine zusätzlichen Kosten für den Austausch der seilführenden Teile anfallen.For example, since the synthetic rope can replace the steel cable in a crane, it is preferable in such cases when the synthetic rope has substantially the same diameter as the steel cable that replaces it. As a result, all guide rollers and other cable-carrying parts of the crane remain unchanged, which makes the replacement of the steel cables by synthetic ropes economically interesting because there are no additional costs for the replacement of the cable-carrying parts.
Dies bedeutet aber nicht dass bei einer Vorrichtung, zum Beispiel einem Kran, die speziell für den Einsatz von Synthetikseilen konstruiert ist, nicht an die Synthetikseile optimal angepasste Materialien für Flächen auf denen das Synthetikseil läuft (zum Beispiel Umlenkrollen) Verwendung finden. Auch die Dimensionen der seilführenden Teile und das Material aus dem sie gefertigt sind, wird bei solchen neuen Vorrichtungen an die Verwendung der Synthetikseile angepasst sein, so dass die Vorrichtung insgesamt leichter ausfallen kann, als eine Vorrichtung die für die Verwendung von Stahlseilen konstruiert wurde.This does not mean, however, that in a device, for example a crane specially designed for use with synthetic ropes, materials not optimally adapted to the synthetic ropes are used for surfaces on which the synthetic rope is running (for example pulleys). Also, the dimensions of the cable guiding parts and the material of which they are made will be adapted to the use of synthetic ropes in such new devices, so that the device as a whole may be lighter than a device designed for use with steel cables.
Da das Synthetikseil bei gleichen Anforderungen wie an das Stahlseil andere Maße, bezogen auf den Durchmesser, und andere Wickeleigenschaften aufweist, kann die Vorrichtung bevorzugt eine Winde oder mehrere Winden aufweisen, die speziell für das Aufwickeln von Synthetikseilen geeignet ist oder sind. Solche Winden sind beispielsweise speziell angepasste Doppelscheibenwinden (double capstan winch) oder Trommelwinden mit kleineren Durchmessern als für Stahlseile gleicher Seillänge, und damit reduziertem Gewicht.Since the synthetic rope has other dimensions, in relation to the diameter and other winding properties, with the same requirements as the steel cable, the device may preferably have one or more winches which are or are particularly suitable for winding synthetic ropes. Such winches are for example specially adapted double capstan winches or drum winches with smaller diameters than steel cables of the same rope length, and thus reduced weight.
Die Dichte von Stahl entspricht mit 7,85kg/dm3 etwa dem 8-fachen der Dichte eines bevorzugten Synthetikseils. Bei einer Seillänge von zum Beispiel 290m entspricht das einem Gewichtsunterschied von ungefähr 600kg. Durch das niedrigere Eigengewicht des Seils und eventuelle weitere Gewichtsvorteile durch leichtere Seiltrommeln kann vorteilhafter Weise die Traglast der Vorrichtung erhöht werden.The density of steel at 7.85kg / dm 3 is about 8 times the density of a preferred synthetic rope. With a rope length of for example 290m this corresponds to a weight difference of about 600kg. Due to the lower weight of the rope and any further weight advantages through lighter rope drums can advantageously be increased, the load of the device.
In oder neben der Basis weist die Vorrichtung ein Antriebsaggregat auf, das mit der oder den Seiltrommeln gekoppelt oder koppelbar ist und mittels dem das Synthetikseil auf die Seiltrommel aufgewickelt und von der Seiltrommel abgewickelt werden kann.In or next to the base, the device has a drive unit which can be coupled or coupled to the rope drum or drums and by means of which the synthetic rope can be wound onto the rope drum and unwound from the rope drum.
Synthetikfasern haben den weiteren Vorteil, dass sie aufgrund ihres geringen Gewichts leichter handhabbar sind als herkömmliche Stahlseile und dass im Gegensatz zum Stahlseil, zum Beispiel beim Anhängen einer Last keine Verletzungsgefahr durch vorstehende "Fleischhaken" für den Arbeiter besteht. Aufgrund ihres geringen Eigengewichts reduzieren sie insgesamt das Verletzungsrisiko im Einsatz.Synthetic fibers have the further advantage that they are easier to handle because of their low weight than conventional steel cables and that in contrast to the steel cable, for example when attaching a load there is no risk of injury to the worker by protruding "meat hooks". Due to their low weight, they reduce the overall risk of injury during use.
