Abstract
Description
Die Erfindung betrifft einen Teleskopkran bestehend aus einem Unterwagen, einem
drehbar darauf angeordneten Oberwagen, einem Gegengewicht und einem Ausleger
gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to a telescopic crane consisting of an undercarriage, a
Upper carriage rotatably arranged on it, a counterweight and a boom
according to the preamble of
Teleskopkrane sind im ausgefahrenen Zustand je nach Anstellwinkel unterschiedlich großen Belastungen ausgesetzt. In Steilstellung ist oftmals die seitliche Verformung des Hauptauslegers das traglastbegrenzende Kriterium. Bei einem flachen bzw. mittleren Anstellwinkel sind die in der Einspannung der ausgefahrenen Teleskopschüsse auftretenden Belastungen ein wesentliches Kriterium für die maximale Traglast. Für den letztgenannten Belastungsfall ist als Momentenentlastung der sog. Superliftbetrieb entwickelt worden.When extended, telescopic cranes differ depending on the angle of attack exposed to great stress. The lateral deformation is often in a steep position of the main boom the criterion limiting the load capacity. With a flat or mean angles of attack are those in the clamping of the extended Telescopic shots occurring loads an essential criterion for the maximum load. For the latter case of load is a moment relief the so-called super lift operation was developed.
Teleskopkrane mit Superliftbetrieb sind seit langem bekannt (s. Auszug
Firmenprospekt Mannesmann Demag Fördertechnik; Demag AC 1600; 04/96, Seiten
5, 17 und 27). Zur Erhöhung der Traglast und zur Minderung der Durchbiegung des
ausgefahrenen Hauptauslegers ist am Grundkasten des Hauptauslegers ein auf den
Grundkasten ablegbarer Abspannbock angeordnet, der mit einer nahezu
längenunveränderbaren Abspannung mit dem Fußbereich des Hauptauslegers
einerseits und mit einer weiteren Abspannung, die im Regelfall längenveränderbar ist,
mit dem Kopf bzw. Kragen eines der inneren Teleskopschüsse andererseits
verbunden. Diese versteifende Anordnung ist anwendbar für das Grundgerät allein,
aber auch in Verbindung mit der Anordnung eines aus Gittermastteilen gebildeten
starren oder wippbaren Hilfsauslegers. Telescopic cranes with superlift operation have been known for a long time (see excerpt
Company brochure Mannesmann Demag Fördertechnik; Demag AC 1600; 04/96,
Aufgabe der Erfindung ist es, einen Teleskopkran anzugeben, dessen seitliche Verformung des Auslegers, insbesondere in Steilstellung signifikant geringer ist als bei bekannten Teleskopkranen.The object of the invention is to provide a telescopic crane, the lateral Deformation of the boom, especially in the steep position, is significantly less than at known telescopic cranes.
Diese Aufgabe wird ausgehend vom Oberbegriff in Verbindung mit den
kennzeichnenden Merkmalen des Anspruches 1 gelöst. Vorteilhafte Weiterbildungen
sind jeweils Gegenstand von Unteransprüchen.This task is based on the generic term in conjunction with the
characterizing features of
Nach der Lehre der Erfindung ist am Ausleger mindestens eine gegenüber der Wippebene geneigte Abspannstütze angeordnet, die mit einem im Wesentlichen in Längsrichtung des Auslegers verlaufenden Spannmittel verbunden ist, wobei die Neigung der Abspannstütze so gewählt ist, dass die auf den Ausleger wirkende seitliche Belastung teilweise oder vollständig durch die Abspannung aufgenommen wird. Die Neigung der Abspannstütze kann quer zur Längsrichtung oder in Längsrichtung oder überlagernd quer zur und in Längsrichtung des Auslegers erfolgen.According to the teaching of the invention, at least one is opposite to the boom Rocker plane inclined guy support arranged with a substantially in Longitudinal direction of the boom extending clamping means is connected, the The angle of the guy support is selected so that it acts on the boom lateral or partial load is absorbed by the guying becomes. The inclination of the guy support can be transverse to the longitudinal direction or in Longitudinal direction or superimposed transversely to and in the longitudinal direction of the boom.
Vorzugsweise sind auf der Oberseite des jeweiligen Auslegerelementes zwei geneigte Abspannstützen vorgesehen, wobei im Regelfall die Winkelneigung beider Abspannstützen gleich ist. Sie kann aber je nach Richtung der am Ausleger angreifenden Kräfte auch verschieden sein. Die Fußenden beider Abspannstützen können an einer gemeinsamen Stelle mit der Oberseite des Auslegers verbunden sein, aber ebenso auch versetzt zueinander. Nach einem weiteren Merkmal der Erfindung ist das Fußende wenigstens einer Abspannstütze im Übergangsbereich zwischen Oberseite oder jeweiliger Seitenwand mit dem Ausleger verbunden. Alternativ gibt es auch die Möglichkeit, das Fußende wenigstens einer Abspannstütze auf einen quer zur Längsachse des Auslegers und über diesen hinauskragenden Träger anzuordnen.Preferably, two are inclined on the top of the respective boom element Guy braces are provided, usually the angular inclination of both Guy supports are the same. However, depending on the direction of the boom attacking forces may also be different. The foot ends of both guy supports can be connected to the top of the boom at a common location, but also offset from each other. According to a further feature of the invention is the foot end of at least one guy support in the transition area between Top side or respective side wall connected to the boom. Alternatively there is also the possibility to cross the foot end of at least one guy support To arrange the longitudinal axis of the boom and overhanging this beam.
Die vorgeschlagene Anordnung hat den Vorteil, dass je nach Winkelstellung der Abspannstützen der Anteil der Abspann kraft, der in die Seitenrichtung wirksam wird, stufenlos oder kontinuierlich verändert werden kann. Im Falle der Anordnung von zwei versetzt angeordneten Abspannstützen bedeutet dies, dass in der einen Extremlage, d. h. in der Vertikalstellung, die beiden parallel stehenden Abspannstützen die gleiche Wirkung im Sinne eines Superliftbetriebes haben wie der bekannte Abspannbock. In einer Winkelstellung <90° bis >0° für die beiden Abspannstützen wird die wirksame Spannkraft aufgeteilt in eine Komponente Superliftbetrieb und eine Komponente seitliche Abspannung. In der zweiten Extremlage, d. h. in der Horizontalstellung, bewirken die beiden Abspannstützen nur eine Verstärkung in beide Seitenrichtungen.The proposed arrangement has the advantage that, depending on the angular position Guy supports: the amount of guy force that acts in the lateral direction can be changed continuously or continuously. In the case of the arrangement of two this means that in one extreme position, d. H. in the vertical position, the two guy supports in parallel are the same Effect in the sense of a superlift operation like the well-known guy stand. In an angular position <90 ° to> 0 ° for the two guy supports becomes the effective one Clamping force divided into a superlift operation component and a component lateral guying. In the second extreme position, i.e. H. in the horizontal position, the two guy supports only reinforce in both directions.
Das jeweilig freie Kopfende der Abspannstütze ist über ein erstes Spannmittel wahlweise mit dem Unterwagen, dem Oberwagen, dem Fußbereich des Auslegers, dem festen oder separat geführten Gegengewicht oder dem Boden in Richtung Fußende des Auslegers und über ein weiteres Spannmittel mit einer ausgewählten Stelle des Auslegers in Richtung Auslegerkopf verbunden. Die jeweils gewünschte Winkelstellung der Abspannstützen kann stufenweise oder kontinuierlich über ein Verschwenken der Abspannstützen eingestellt werden. Damit ist auch eine asymmetrische Winkeleinstellung möglich. Dies bedeutet, dass bei einer angreifenden Seitenkraft nur an einer Seite die jeweilige Abspannstütze mehr in Richtung seitlicher Abspannung geneigt wird, während die zweite Abspannstütze in einer Mittellage verbleibt.The respective free head end of the guy support is over a first clamping device optionally with the undercarriage, the uppercarriage, the foot area of the boom, the fixed or separately guided counterweight or the floor in the direction Foot end of the boom and a further clamping device with a selected one Place the boom connected in the direction of the boom head. The one you want Angular position of the guy supports can be gradual or continuous Swiveling the guy supports can be adjusted. So that's one asymmetrical angle adjustment possible. This means that when attacking Lateral force only on one side the respective guy support more towards the side Guy is inclined while the second guy support is in a central position remains.
Da auch der Abstand der Spannmittel vom Ausleger Einfluss auf die gewünschte Verstärkung hat, ist vorgesehen, die Länge der Abspannstützen in Stufen oder kontinuierlich zu verändern. Die Spannmittel können als Seil oder als Stange ausgebildet sein. Das Spannmittel bzw. die Spannmittel können mit und ohne Vorspannung angeordnet werden. Im Falle einer Vorspannung und eines nachregulierbaren Spanngrades wirkt das Spannmittel mit einer Spannvorrichtung zusammen. Vorzugsweise ist dies eine Winde oder eine Kolben-Zylinder-Einheit. Aber auch die Winkelverstellung und/oder die Längenänderung der Abspannstütze kann im Sinne einer Spannvorrichtung genutzt werden. Die Spannvorrichtungen sind wahlweise an den Abspannstützen, am Ausleger, am Ober- oder Unterwagen oder am Gegengewicht anordenbar.Since the distance of the clamping devices from the boom also influences the desired Reinforcement has been provided, the length of the guy supports in steps or to change continuously. The clamping devices can be used as a rope or as a rod be trained. The clamping device or the clamping device can be with and without Preload can be arranged. In the case of a preload and one The clamping device can be adjusted with a clamping device together. This is preferably a winch or a piston-cylinder unit. But also the angle adjustment and / or the change in length of the guy support can in Can be used as a tensioning device. The jigs are either on the guy supports, on the boom, on the superstructure or undercarriage or on Counterweight can be arranged.
Vorzugsweise werden die Abspannstützen am Kauptausleger im Bereich des Grundkastens angeordnet, insbesondere im vorderen Bereich zwischen der Anlenkung des Wippzylinders und der vorderem Lagerung. Zur kontinuierlichen Verstellung der Abspannstützen ist vorzugsweise jede Abspannstütze mit einer auf dem Grundkasten sich abstützenden Kolben-Zylinder-Einheit verbunden. Zur Anordnung der Winde weist nach einem weiteren Merkmal der Erfindung die Abspannstütze zwei Holme auf, zwischen denen die Winde anordenbar ist. The guy supports on the main boom are preferably in the area of the Basic box arranged, especially in the front area between the Linkage of the luffing cylinder and the front bearing. For continuous Adjustment of the guy supports is preferably every guy support with one on the piston-cylinder unit supported on the basic box. For Arrangement of the winch has according to a further feature of the invention Guy support on two spars, between which the winch can be arranged.
Die Ausrüstung des Teleskopauslegers kann noch ergänzt werden mit der Anordnung eines aus Gittermastteilen gebildeten starren oder wippbaren Hilfsauslegers. Auch an diese Auslegerelemente kann die vorgeschlagene seitliche Abspannung angebracht werden.The equipment of the telescopic boom can be supplemented with the arrangement a rigid or luffing jib made of lattice boom parts. Also on the proposed lateral bracing can be attached to these cantilever elements become.
Besonders wirkungsvoll kann die seitliche Abspannung eingesetzt werden, wenn der Kran mit einem Messmittel zur Erfassung der seitlichen Verformung des Auslegers versehen ist. Überschreitet die Verformung einen festgelegten zulässigen Wert, wird das mit der Abspannung verbundene Spannmittel aktiviert und die Abspannung nachgespannt. Der Grad der seitlichen Verformung kann direkt oder indirekt über Krangrößen ermittelt werden. Beispielsweise sind dies die Seilspannung, die Seillänge und Seildehnung. Aber auch über die an den Ausleger angreifenden Kräfte in Form des seitlich auftretenden Windes, der Sonneneinstrahlung sowie der im Ausleger vorherrschenden Temperaturen kann eine Aussage über den Grad der seitlichen Verformung gemacht werden.The side guying can be used particularly effectively if the Crane with a measuring device to record the lateral deformation of the boom is provided. If the deformation exceeds a specified permissible value, the tensioning device connected to the guying is activated and the guying tightened. The degree of lateral deformation can be direct or indirect Crane sizes can be determined. For example, these are the rope tension, the rope length and rope elongation. But also about the forces acting on the boom in form the side wind, the sun and the boom prevailing temperatures can make a statement about the degree of lateral Deformation can be made.
