Description

Die Erfindung betrifft eine Krananordnung mit einem Mast oder Kranausleger, an welchem mindestens eine Umlenkrolle angeordnet ist, über welche mindestens ein Kranseil im Wesentlichen vertikal nach unten geführt ist, wobei das Kranseil an seinem freien Ende ein Abschlusselement aufweist, einer Seilwinde zum Betätigen des Kranseils und einer Abschalteinrichtung zum Abschalten der Seilwinde bei Annäherung des Abschlusselementes des Kranseils an die Umlenkrolle, wobei die Abschalteinrichtung einen Anschlaghebel aufweist, durch den bei Kontakt mit dem Anschlusselement das Abschalten bewirkbar ist, gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a crane arrangement with a mast or crane boom, on which at least one guide roller is arranged, via which at least one crane rope is guided substantially vertically downwards, wherein the crane cable has at its free end a closing element, a winch for operating the crane rope and a shut-off device for switching off the winch when approaching the end element of the crane rope to the deflection roller, wherein the shut-off device has a stop lever, by the shutdown is effected upon contact with the connection element, according to the preamble of claim 1.

Eine gattungsgemäße Krananordnung geht beispielsweise aus der DE 28 46 394 A1 hervor. Diese bekannte Krananordnung offenbart einen Ladebaum, an welchem ein Kranseil mit einem Kranhaken vertikal verstellbar angehängt ist. Am Kopf des Ladebaums ist eine Abschalteinrichtung, auch Hubendschalter genannt, mit einem Anschlaghebel angeordnet. Der Anschlaghebel ist über eine Kette an einer Schalteinheit aufgehängt. An dem Anschlaghebel ist eine Öse angeordnet, durch welche das Kranseil hindurchgeführt ist. Bei einem nach oben Ziehen des Kranhakens wird der Anschlaghebel nach oben verschoben. Dadurch wird ein federgespannter Schalthebel der Schalteinheit entlastet, wodurch ein Abschalten der Seilwinde des Kranseils bewirkt wird.A generic crane arrangement is for example from the DE 28 46 394 A1 out. This known crane arrangement discloses a loading boom on which a crane cable with a crane hook is attached vertically adjustable. At the top of the ladle is a turn-off, also called stroke limit, arranged with a stop lever. The stop lever is suspended by a chain on a switching unit. At the stop lever, an eyelet is arranged, through which the crane cable is passed. When the crane hook is pulled upwards, the stop lever is moved upwards. As a result, a spring-loaded shift lever of the switching unit is relieved, causing a shutdown of the winch of the crane rope is effected.

Bei dieser bekannten Krananordnung kann es etwa bei einer Verschmutzung des Kranseiles oder beim Einsatz eines stärkeren Kranseiles zu unbeabsichtigten oder vorzeitigen Abschaltungen der Seilwinde kommen. Dies kann den Betriebsablauf erheblich stören.In this known crane arrangement, it can come about at a contamination of the crane rope or when using a stronger crane rope to unintentional or premature shutdowns of the winch. This can significantly disrupt the operation.

Aus der EP 0 677 479 A1 geht ein Gewicht für einen solchen Hubendschalter hervor.From the EP 0 677 479 A1 goes out a weight for such a limit switch.

Eine Krananordnung mit einer Abschalteinrichtung, bei welcher an dem Kranseil ein RFID-Transponder eingesetzt wird, geht aus der WO 2012/166864 A2 hervor. Die Abschalteinrichtung weist dabei ein entsprechendes elektronisches Lesegerät am Mastkopf auf. Elektronische Lesegeräte sind grundsätzlich empfindlich, was insbesondere beim Einsatz an exponierten Mastköpfen an Krananordnungen im Außenbereich kritisch ist und zu Problemen führen kann. Zudem ist am Kranseil positionsgenau ein entsprechender RFID-Chip vorzusehen. Beim Einsatz des Kranseiles etwa an Baugeräten besteht grundsätzlich die Gefahr einer Beschädigung, eines Versetzens oder eines Entfernens des Chips am Kranseil. Hierdurch kann die Funktionsfähigkeit der Abschalteinrichtung beeinträchtigt oder sogar außer Funktion gesetzt werden.A crane assembly with a shutdown device, in which an RFID transponder is used on the crane cable, goes out of the WO 2012/166864 A2 out. The shutdown device has a corresponding electronic reader on the mast head. Electronic readers are generally sensitive, which is particularly critical when used on exposed mast heads on outdoor crane arrangements and can cause problems. In addition, a corresponding RFID chip has to be provided on the crane rope with exact position. When using the crane rope, for example on construction equipment, there is always the risk of damage, staggering or removal of the chip on the crane rope. As a result, the functionality of the defeat can be impaired or even disabled.

Ein Überlaufen eines Kranseiles über eine vorgegebene Endposition hinaus kann jedoch zu Beschädigungen am Kranseil, dem Kranhaken, der Umlenkeinrichtung, dem Mastkopf und/oder der Seilwinde führen.However, overflowing a crane cable beyond a predetermined end position may result in damage to the crane cable, the crane hook, the deflection device, the mast head and / or the cable winch.

Der Erfindung liegt die Aufgabe zugrunde, eine Krananordnung mit einer Abschalteinrichtung vorzusehen, welche bei einem einfachen Aufbau besonders flexibel und zuverlässig einsetzbar ist.The object underlying the invention is to provide a crane arrangement comprising a switch-off device which is particularly flexible and can be used reliably with a simple structure.

Die Aufgabe wir nach der Erfindung durch eine Krananordnung mit den Merkmalen des Anspruchs 1 gelöst. Bevorzugte Ausführungsformen der Erfindung sind in den abhängigen Ansprüchen angegeben.The object we achieved according to the invention by a crane arrangement with the features of claim 1. Preferred embodiments of the invention are indicated in the dependent claims.

Die erfindungsgemäße Krananordnung ist dadurch gekennzeichnet, dass die Abschalteinrichtung mindestens einen ersten Anschlaghebel und einen zweiten Anschlaghebel aufweist, welche unter Ausbildung eines Durchganges voneinander beabstandet sind, dass der erste Anschlaghebel und der zweite Anschlaghebel zum Verändern des Durchgangs verstellbar sind und dass das Kranseil durch den verstellbaren Durchgang hindurchgeführt ist.The crane assembly according to the invention is characterized in that the shut-off device has at least one first stop lever and a second stop lever, which are spaced apart to form a passage that the first stop lever and the second stop lever for changing the passage are adjustable and that the crane cable through the adjustable Passage is passed.

Eine Grundidee der Erfindung kann darin gesehen werden, dass als Abschalteinrichtung weiterhin eine im Wesentlichen mechanische Schalteinrichtung mit Anschlaghebeln vorgesehen ist. Dabei sind mindestens zwei Anschlaghebel vorgesehen, welche zueinander verstellbar sind. Zwischen den beiden Anschlaghebeln ist ein Durchgang für das Kranseil gebildet. Durch die Verstellbarkeit der Anschlaghebel zueinander kann der Durchgang ohne weiteres verstellt und an unterschiedliche Kranseile oder Abschlusselemente, vorzugsweise Kranhaken, vorgesehen werden. Das Verstellen der Anschlaghebel zueinander kann durch das Bedienpersonal mittels herkömmlicher Werkzeuge erfolgen. Die erfindungsgemäße Krananordnung ist somit besonders flexibel und robust.A basic idea of the invention can be seen in the fact that a substantially mechanical switching device with stop levers is furthermore provided as the shutdown device. At least two stop levers are provided, which are mutually adjustable. Between the two stop levers a passage for the crane rope is formed. Due to the adjustability of the stop lever to each other the passage can easily be adjusted and provided to different crane ropes or end elements, preferably crane hooks. The adjustment of the stop lever to each other can be done by the operator by means of conventional tools. The crane arrangement according to the invention is thus particularly flexible and robust.

Grundsätzlich können die Anschlaghebel beliebig ausgebildet sein. Bevorzugt ist es nach einer Weiterbildung der Erfindung, dass die Anschlaghebel stangenförmig ausgebildet sind und parallel zueinander angeordnet sind. Die Stangen können dabei eine zylindrische oder eckige, insbesondere rechteckige Außenkontur aufweisen. Sie sind somit kostengünstig aus Standardprofilen herstellbar.In principle, the stop levers can be designed as desired. It is preferred according to a development of the invention that the stop lever are rod-shaped and are arranged parallel to each other. The rods can have a cylindrical or angular, in particular rectangular outer contour. They are thus inexpensive to produce from standard profiles.

Eine weitere bevorzugte Ausführungsform der Erfindung besteht darin, dass die Anschlaghebel an mindestens einer Querstange verstellbar gelagert sind. Die Anschlaghebel können so entlang der Querstange einfach verstellt und fixiert werden.A further preferred embodiment of the invention consists in that the stop levers are adjustably mounted on at least one crossbar. The stop levers can be easily adjusted and fixed along the crossbar.

Besonders vorteilhaft ist es dabei, dass zwei gegenüberliegende Querstangen vorgesehen sind, welche mit den Anschlaghebeln einen Anschlagrahmen bilden. Dabei sind vorzugsweise die Querstangen im Wesentlichen gleich zueinander ausgebildet. Es wird durch die zwei gegenüberliegenden Querstangen und die dazwischenliegenden zwei oder mehr Anschlaghebeln ein besonders stabiler Aufbau des Anschlagrahmens erreicht.It is particularly advantageous that two opposite transverse rods are provided which form a stop frame with the stop levers. In this case, preferably, the transverse rods are formed substantially equal to each other. It is achieved by the two opposite crossbars and the intermediate two or more stop levers a particularly stable construction of the stop frame.

Weiterhin ist es nach einer Ausführungsvariante der Erfindung bevorzugt, dass die Anschlaghebel und/oder der Anschlagrahmen an mindestens einer Schalteinheit aufgehängt sind, welche bei Entlastung ein Abschaltsignal abgibt. Das am Kranseil angebrachte Abschlusselement, welches jedoch nicht zwingend am Ende eines Kranseils angeordnet sein muss, sondern hiervon auch beabstandet sein kann, wird der an einer Schalteinheit aufgehängte Anschlaghebel beziehungsweise der aufgehängte Anschlagrahmen entlastet. Diese Entlastung kann durch ein entsprechendes elektrisches oder elektronisches Schaltelement erfasst werden, wodurch eine Abschaltung der Seilwinde bewirkbar ist.Furthermore, it is preferred according to an embodiment of the invention that the stop lever and / or the stop frame are suspended from at least one switching unit, which emits a shutdown signal upon discharge. The attachment element attached to the crane rope, which, however, does not necessarily have to be arranged at the end of a crane cable, but can also be spaced therefrom, is relieved of the stop lever suspended on a shift unit or of the suspended stop frame. This discharge can be detected by a corresponding electrical or electronic switching element, whereby a shutdown of the winch is effected.

Dies kann etwa durch Öffnen oder Schließen eines Schaltkreises bei einer entsprechenden Verschiebung der Anschlaghebel erreicht werden. Grundsätzlich ist auch durch einen sonstigen Sensor oder einen Kontaktsensor ein Abschaltsignal abgebbar, wodurch dann eine Abschaltung der Seilwinde über eine entsprechende Steuereinheit erfolgt.This can be achieved for example by opening or closing a circuit with a corresponding displacement of the stop lever. In principle, a switch-off signal can also be emitted by another sensor or a contact sensor, whereby then a shutdown of the winch via a corresponding control unit takes place.

Eine besonders gute Verstellmöglichkeit wird nach einer Weiterbildung der Erfindung dadurch erreicht, dass die mindestens eine Querstange mindestens eine Führung aufweist, entlang welcher mindestens ein Anschlaghebel verschiebbar und verstellbar gelagert ist. Die Führung kann dabei vorzugsweise eine Führungskulisse in der mindestens einen Querstange sein. Die Führungskulisse kann einen Verschiebeweg gegebenenfalls mit bestimmten Rastpositionen vorgeben.A particularly good adjustment is achieved according to a development of the invention in that the at least one crossbar has at least one guide along which at least one stop lever is slidably and adjustably mounted. The guide may preferably be a guide link in the at least one crossbar. The guide slot can optionally specify a displacement with certain locking positions.

Eine weitere bevorzugte Möglichkeit zur Verstellung bei einer erfindungsgemäßen Krananordnung besteht darin, dass die mindestens eine Querstange vorgegebene Justierpositionen aufweist, an denen mindestens ein Anschlagelement verstellbar ist. Die Justierpositionen können vorgegebene Bohrungen, Rastnasen oder andere Justierelemente sein, welche mit einer entsprechenden Ausbildung an den Anschlaghebeln korrespondieren. Insgesamt können so mehrere bestimmte Justierpositionen für mindestens einen Anschlaghebel vorgegeben sein.A further preferred possibility for adjustment in a crane arrangement according to the invention is that the at least one transverse rod has predetermined adjustment positions at which at least one stop element is adjustable. The adjustment positions may be predetermined bores, latching noses or other adjusting elements, which correspond to a corresponding training on the stop levers. Overall, so several specific adjustment positions can be specified for at least one stop lever.

Eine weitere vorteilhafte Ausführungsform der Erfindung kann darin gesehen werden, dass die mindestens eine Querstange ein erstes Querstangenelement und ein zweites Querstangenelement aufweist, welche zueinander verstellbar sind, und dass an dem ersten Querstangenelement der erste Anschlaghebel und an dem zweiten Querstangenelement der zweite Anschlaghebel angeordnet ist. Bei Anordnung von zwei oder mehr Querstangen können auch diese Querstangen entsprechend aus mehreren Querstangenelementen aufgebaut sein. Die Querstangenelemente können vorzugsweise verschiebbar oder verschwenkbar zueinander gelagert sein.A further advantageous embodiment of the invention can be seen in that the at least one crossbar has a first crossbar element and a second crossbar element, which are mutually adjustable, and that the first stop lever and the second crossbar element of the second stop lever is arranged on the first crossbar member. If two or more cross bars are arranged, these cross bars can also be constructed correspondingly from a plurality of crossbar elements. The crossbar elements can preferably be mounted displaceably or pivotably to one another.

Dabei besteht eine besonders bevorzugte Ausführungsform darin, dass die beiden Querstangenelemente zueinander teleskopierbar geführt sind. Dabei ist zumindest ein Querstangenelement rohrförmig ausgebildet, wobei das andere Querstangenelement in den Rohrhohlraum einführbar und verschiebbar gelagert ist. Eine Fixierung kann über entsprechende Rastelemente oder eine Klemmung, etwa durch eine Klemmschraube erfolgen.In this case, a particularly preferred embodiment is that the two crossbar elements are guided to each other telescopically. In this case, at least one crossbar element is tubular, wherein the other crossbar element is inserted and slidably mounted in the tube cavity. A fixation can be done via appropriate locking elements or a clamp, such as a clamping screw.

Eine weitere mögliche Ausführungsform der Erfindung besteht darin, dass die Querstangenelemente über ein Gelenk miteinander verstellbar verbunden sind. Es kann so eine scherenartige Verstellbewegung zwischen den Querstangenelementen ermöglicht sein. Weiterhin können auch die Anschlaghebel über Gelenke mit den Querstangen verbunden sein, so dass etwa eine trapezartige Verstellung der Querstangen und der Anschlaghebel und damit eine entsprechende Vergrößerung oder Verkleinerung des Durchganges zwischen den Anschlaghebeln einstellbar ist.Another possible embodiment of the invention is that the crossbar elements are connected to each other adjustable via a joint. It can so a scissor-like adjustment between the cross bar elements allows. Furthermore, the stop lever can be connected via joints with the cross bars, so that about a trapezoidal adjustment of the cross bars and the stop lever and thus a corresponding increase or decrease in the passage between the stop levers is adjustable.

Die Erfindung umfasst weiterhin ein Baugerät, insbesondere einen Kran, mit einer erfindungsgemäßen Krananordnung, wie diese zuvor beschrieben worden ist. Grundsätzlich kann die Krananordnung auch zu beliebigen anderen Zwecken eingesetzt werden.The invention further comprises a construction device, in particular a crane, with a crane arrangement according to the invention, as has been previously described. In principle, the crane arrangement can also be used for any other purposes.

Bei einer ersten erfindungsgemäßen Krananordnung 10 gemäß Fig. 1 ist von einem grundsätzlich vertikal angeordneten Mast 12, welcher beispielsweise an einem nichtdargestellten Baugerät, etwa einem Bohrgerät angeordnet ist, lediglich ein Teil eines Mastkopfes 14 dargestellt. Der am oberen Ende des Mastes 12 angeordnete Mastkopf 14 weist zwei Umlenkrollen 16 auf, welche um eine horizontal gerichtete Drehachse drehbar gelagert sind. Um die beiden Umlenkrollen 16 ist jeweils ein Kranseil 20 vom Mast 12 vertikal nach unten geführt. Vorzugsweise an einem freien Endbereich des mindestens einen Kranseiles 20 ist ein nicht-dargestelltes Abschlusselement befestigt, beispielsweise ein Kranhaken oder eine Seillasche, welche einen Nutzbereich des Kranseils begrenz oder abschließt.In a first crane arrangement 10 according to the invention Fig. 1 is of a basically vertically arranged mast 12, which is arranged for example on a construction equipment, not shown, such as a drill, only a part of a mast head 14 is shown. The arranged at the upper end of the mast 12 mast head 14 has two guide rollers 16 which are rotatably mounted about a horizontally directed axis of rotation. To the two pulleys 16 is a crane rope 20 from the mast 12 is guided vertically downwards. Preferably, at a free end portion of the at least one crane cable 20, a non-illustrated end element is attached, for example, a crane hook or a rope bag, which limits or closes a working area of the crane cable.

Um eine Kollision des Abschlusselementes mit den Umlenkrollen 16 oder dem Mastkopf 14 zu vermeiden, ist bei der erfindungsgemäßen Krananordnung 10 an am Mastkopf 14 vorgesehenen Tragarmen 18 eine schaukelartige Abschalteinrichtung 30 angebracht, welche nachfolgend näher beschrieben wird.In order to avoid a collision of the closing element with the deflection rollers 16 or the mast head 14, a rocking-type shut-off device 30 is mounted in the crane assembly 10 according to the invention provided on the mast head 14 support arms 18, which will be described in more detail below.

Die Abschalteinrichtung 30 weist einen ersten stangenförmigen Anschlaghebel 32a und einen parallel dazu und im Wesentlichen gleich ausgebildeten zweiten Anschlaghebel 32b auf. Unter Ausbildung eines Anschlagrahmens 38 sind die beiden Anschlaghebel 32a, 32b an ihren Enden in nut- oder kulissenartigen Führungen 40 von seitlichen Querstangen 36 verschiebbar gelagert. Zusätzlich kann der Durchgang 34 durch eine mittige Einstellleiste 35 eingestellt und fixiert sein. Über die Führungen 40 können die beiden Anschlaghebel 32 in ihrem Abstand zueinander verstellt werden, wobei zwischen den beiden Anschlaghebeln 32 ein Durchgang 34 für das mindestens eine Kranseil 20 gebildet ist. Durch entsprechende Feststellschrauben an den Enden der Anschlaghebel 32 können diese in ihrer gewünschten Position an den Querstangen 36 fixiert werden. Dabei wird eine Breite des Durchgangs 34 gemäß der Erfindung so eingestellt, dass das Kranseil 20 reibungsfrei oder zumindest weitgehend reibungsfrei hindurchläuft, während ein Abschlusselement am Kranseil 20 nicht durch den Durchgang 34 hindurchtreten kann.The shut-off device 30 has a first rod-shaped stop lever 32a and a second stop lever 32b which is parallel thereto and essentially identically designed. To form a stop frame 38, the two stop levers 32a, 32b are slidably mounted at their ends in groove or gate-like guides 40 of lateral cross bars 36. In addition, the passage 34 may be adjusted and fixed by a central adjustment bar 35. About the guides 40, the two stop lever 32 can be adjusted in their distance from each other, wherein between the two stop levers 32, a passage 34 for the at least one crane cable 20 is formed. By appropriate locking screws at the ends of the stop lever 32, these can be fixed in their desired position on the transverse rods 36. In this case, a width of the passage 34 is adjusted according to the invention so that the crane cable 20 passes frictionless or at least substantially without friction, while a closure element on the crane cable 20 can not pass through the passage 34.

Der so gebildete Anschlagrahmen 38 ist über seitliche Aufhängeseile 37 und jeweils einer Verbinderanordnung 39 an einer Schalteinheit 50 aufgehängt.The stop frame 38 thus formed is suspended by means of lateral suspension cables 37 and in each case one connector arrangement 39 on a switching unit 50.

Aufgrund des Gewichts des Anschlagrahmens 38 befinden sich die beiden Schalteinheiten 50 in einer ersten Schaltposition. Üblicherweise ist bei dieser ersten Schaltposition der Betrieb der Seilwinde zum Bewegen des Kranseiles 20 freigegeben. Schlägt das Abschlusselement des Kranseiles 20 an den Anschlaghebel 32 des Anschlagrahmens 38 an, so wird der Anschlagrahmen 38 angehoben und die Verbinderanordnung 39 mit der Aufhängung an den Schalteinheiten 50 entlastet. Durch diese Entlastung schaltet die Schalteinheit so jeweils in eine zweite Schaltposition, bei welcher ein Stopp der Seilwinde bewirkt wird. Hierzu sind die Schalteinheiten 50 in elektrischer oder elektronischer Weise drahtlos oder drahtgebunden mit einer Steuereinheit oder unmittelbar mit einem Antrieb der Seilwinde verbunden. Diese ist in der Fig. 1 nicht näher dargestellt.Due to the weight of the stop frame 38, the two switching units 50 are in a first switching position. Usually, in this first switching position, the operation of the winch for moving the crane cable 20 is released. If the end element of the crane cable 20 strikes against the stop lever 32 of the stop frame 38, the stop frame 38 is lifted and the connector assembly 39 is relieved of the suspension at the switching units 50. By this discharge, the switching unit switches so in each case in a second switching position, in which a stop of the winch is effected. For this purpose, the switching units 50 are connected in an electrical or electronic manner wireless or wired to a control unit or directly to a drive of the winch. This is in the Fig. 1 not shown in detail.

Wird ein anderes Kranseil 20 mit einem anderen Seildurchmesser verwendet, so kann der Abstand der Anschlaghebel 32 und damit die Breite des Durchgangs 34 durch entsprechendes Lösen der Feststellschrauben und Verschieben der Anschlaghebel 32 in den kulissenartigen Führungen 40 verstellt und angepasst werden. Nach Anpassung werden die Anschlaghebel 32 wieder fixiert, so dass ein entsprechend angepasster Durchgang 34 für das geänderte Kranseil 20 gegeben ist.If another crane cable 20 is used with a different rope diameter, the distance of the stop lever 32 and thus the width of the passage 34 can be adjusted and adjusted by correspondingly releasing the locking screws and moving the stop lever 32 in the slide-like guides 40. After adjustment, the stop lever 32 are fixed again, so that a correspondingly adapted passage 34 is given for the changed crane cable 20.
