Description

Die Erfindung betrifft eine Hubvorrichtung der im Oberbegriff des Anspruchs 1 genannten Art.The invention relates to a lifting device referred to in the preamble of claim 1 Art.

Hubvorrichtungen der betreffenden Art sind durch EP 1 446 353 und DE-OS 25 53 221 bekannt. Sie weisen ein an Tragseilen aufgehängtes Lastaufnahmemittel und Mittel zum Auf- bzw. Abwickeln der Tragseile zum Anheben bzw. Absenken des Lastaufnahmemittels auf. Die bekannten Hubvorrichtungen werden zu verschiedenen Aufgaben im Logistikbereich eingesetzt, beispielsweise zum Ein- und Auslagern von Gütern an bzw. von Lagerplätzen eines Hochregallagers.Lifting devices of the type are by EP 1 446 353 and DE-OS 25 53 221 known. They have a load suspension means suspended on suspension cables and means for winding or unwinding the suspension cables for raising or lowering the load suspension means. The known lifting devices are used for various tasks in the logistics sector, for example, for storage and retrieval of goods to or from storage bins of a high-bay warehouse.

In der Praxis weisen die bekannten Hubvorrichtungen eine Notabschaltung auf, die bei einem Notfall die Mittel zum Auf- bzw. Abwickeln der Tragseile, die beispielsweise durch drehangetriebene Wickeltrommeln gebildet sein können, anhalten.In practice, the known lifting devices on an emergency stop, which in an emergency, the means for winding or unwinding of the support cables, which may be formed for example by rotationally driven winding drums, stop.

Durch NL 8 702 283 A ist im Zusammenhang mit einer Hubvorrichtung für Lasten ein Positioniergetriebe bekannt, mittels dessen eine Feinpositionierung des Lastaufnahmemittels bewirkt wird.By NL 8 702 283 A is in connection with a lifting device for loads a positioning known, by means of which a fine positioning of the lifting device is effected.

Durch EP 1 446 353 ist eine Hubvorrichtung für Lasten bekannt, die ein an Tragseilen aufgehängtes Lastaufnahmemittel aufweist. Verfahrbewegungen der Hubvorrichtung werden durch eine Steuerungseinheit gesteuert, die u.a. dazu ausgebildet ist, unerwünschte Pendelbewegungen des Lastaufnahmemittels während einer Verfahrbewegung zu verhindern.By EP 1 446 353 is a lifting device for loads is known, which has a suspension cables suspended on lifting cables. Traversing movements of the lifting device are controlled by a control unit, which is designed, inter alia, unwanted pendulum movements to prevent the lifting device during a movement.

Durch US5022543 ist eine Positioniervorrichtung bekannt, die als steuerbares Kupplungselement zwischen einem Lastaufnahmemittel und einem Tragseil der Hubvorrichtung angeordnet ist.By US5022543 a positioning device is known, which is arranged as a controllable coupling element between a load-receiving means and a supporting cable of the lifting device.

Der Erfindung liegt die Aufgabe zugrunde, eine Hubvorrichtung der im Oberbegriff des Anspruchs 1 genannten Art anzugeben, bei der im Falle einer Notabschaltung die Gefahr einer Beschädigung des Lastaufnahmemittels bzw. daran angeordneter Komponenten verringert ist.The invention has for its object to provide a lifting device referred to in the preamble of claim 1, in which in the event of an emergency shutdown, the risk of damage to the load handling device or components arranged thereon is reduced.

Diese Aufgabe wird durch die im Anspruch 1 angegebene Lehre gelöst.This object is achieved by the teaching defined in claim 1.

Die Erfindung beruht auf der Erkenntnis, daß beim Anheben des Lastaufnahmemittels eine dem Hubvorgang zugeordnete Antriebsvorrichtung, beispielsweise drehangetriebene Trommeln zum Aufwickeln der Tragseile, zwar schlagartig stillgesetzt werden kann, das Lastaufnahmemittel mit darauf aufgenommener Last sich jedoch aufgrund seiner Massenträgheit zunächst weiter aufwärts bewegt, so daß die Tragseile nicht mehr gespannt sind, sondern in gewissem Maße durchhängen. Nach dem Erreichen eines oberen Umkehrpunktes bewirkt die Erdanziehungskraft eine Abwärtsbeschleunigung des Lastaufnahmemittels, das schlagartig abgebremst wird, wenn das Lastaufnahmemittel in die Tragseile zurückfällt und diese somit wieder gespannt sind. Bei der schlagartigen Abbremsung des Lastaufnahmemittels besteht die Gefahr, daß das Lastaufnahmemittel, daran angeordnete Komponenten sowie ggf. die Last, beschädigt oder zerstört werden. Hiervon ausgehend liegt der Erfindung der Gedanke zugrunde, in dem geschilderten Fall die negative Beschleunigung des Lastaufnahmemittels zu begrenzen oder wenigstens zu vermindern. Dementsprechend sieht die Erfindung Mittel zum Vermindern und/oder Begrenzen einer negativen Beschleunigung des Lastaufnahmemittels vor.The invention is based on the finding that when lifting the lifting device associated with a lifting drive device, such as rotating drums for winding the suspension cables, although stopped abruptly, the load receiving means with it picked up load, however, initially moved further upward due to its inertia, so that the ropes are no longer stretched, but sag to some extent. After reaching an upper reversal point, the gravitational force causes a downward acceleration of the lifting device, which is decelerated abruptly when the load-carrying means falls back into the support cables and thus they are stretched again. In the sudden braking of the load-bearing means there is a risk that the load-carrying means, components arranged thereon and possibly the load, damaged or destroyed. On this basis, the invention is based on the idea to limit in the described case, the negative acceleration of the lifting device or at least diminish. Accordingly, the invention provides means for reducing and / or limiting negative acceleration of the load handling means.

Erfindungsgemäß ist somit die negative Beschleunigung des Lastaufnahmemittels in einem Notfall der oben geschilderten Art auf ein Maß begrenzt, bei dem Beschädigungen des Lastaufnahmemittels, daran angeordneter Komponenten bzw. der Last vermieden sind. Falls die negative Beschleunigung des Lastaufnahmemittels in einem Notfall so groß ist, daß sie nicht auf ein eine Beschädigung verhinderndes Maß begrenzt werden kann, so wird die negative Beschleunigung erfindungsgemäß wenigstens vermindert, so daß Beschädigungen des Lastaufnahmemittels sowie der daran angeordneten Komponenten und Last verringert sind.According to the invention, the negative acceleration of the load-receiving means in an emergency of the type described above is thus limited to a level at which damage to the load-carrying means, components arranged thereon or the load is avoided. If the negative acceleration of the load receiving means in an emergency is so great that it can not be limited to a damage preventing measure, the negative acceleration is at least reduced according to the invention, so that damage to the load receiving means and the components and load arranged thereon are reduced.

Auf diese Weise ist die Betriebssicherheit der erfindungsgemäßen Hubvorrichtung wesentlich erhöht. Dies gilt insbesondere für Fälle, in denen mit hohen Hubgeschwindigkeiten beispielsweise von ca. 60 m/min bis ca. 120 m/min, gearbeitet wird.In this way, the reliability of the lifting device according to the invention is substantially increased. This is especially true for cases in which high lifting speeds, for example, from about 60 m / min to about 120 m / min, worked.

Die erfindungsgemäß vorgesehenen Mittel zum Begrenzen und/oder Vermindern der negativen Beschleunigung können mechanisch einfach aufgebaut und damit kostengünstig gestaltet sein.The inventively provided means for limiting and / or reducing the negative acceleration can be constructed mechanically simple and thus designed cost.

Anstelle von Tragseilen können bei der erfindungsgemäßen Hubvorrichtung beispielsweise auch Tragketten oder andere flexible Tragmittel verwendet werden.Instead of carrying ropes, for example, carrying chains or other flexible carrying means can be used in the lifting device according to the invention.

Die Erfindung sieht vor, dass die Mittel zum Begrenzen und/oder Verringern an jedem Tragseil ein mit demselben verbundenes erstes Teil und ein mit dem Lastaufnahmemittel verbundenes zweites Teil aufweisen, die in Tragseilrichtung relativ zueinander verschiebbar mit Reibflächen aneinander anliegen, wobei die Reibkraft so bemessen ist, daß sich die Teile beim Erreichen oder Überschreiten einer vorbestimmten negativen Beschleunigung des Lastaufnahmemittels unter Überwindung der Reibkraft relativ zueinander verschieben. Bei dieser Ausführungsform wirken das erste und das zweite Teil nach Art einer Bremse zusammen.The invention provides that the means for limiting and / or reducing each support cable have a first part connected to the same and a second part connected to the load receiving means, which rest in the carrying cable direction relative to each other slidably with friction surfaces to each other, wherein the friction force so is dimensioned that move the parts relative to each other when reaching or exceeding a predetermined negative acceleration of the load receiving means, overcoming the frictional force. In this embodiment, the first and the second part cooperate in the manner of a brake.

Um die Bremswirkung zu erhöhen, sieht eine vorteilhafte Weiterbildung dieser Ausführungsform vor, daß wenigstens eine der Reibflächen nach Art eines Bremsbelages ausgebildet ist.In order to increase the braking effect, provides an advantageous development of this embodiment, that at least one of the friction surfaces is designed in the manner of a brake pad.

Eine andere vorteilhafte Weiterbildung der Erfindung sieht vor, daß die Reibkraft einstellbar ist. Bei einer geringen Reibkraft beginnt bei dieser Ausführungsform eine Relativverschiebung des ersten Teiles und des zweiten Teiles zueinander bereits bei einer relativ geringen negativen Beschleunigung des Lastaufnahmemittels, während einer höheren Reibkraft die Relativbewegung des ersten Teiles und des zweiten Teiles erst bei einer relativ hohen negativen Beschleunigung beginnt. Durch Einstellung der Reibkraft ist somit einstellbar, bei welcher negativen Beschleunigung die Mittel zum Begrenzen bzw. Verringern der negativen Beschleunigung des Lastaufnahmemittels wirksam werden. Damit ist beispielsweise und insbesondere einstellbar, auf welchen Wert die negativen Beschleunigung erfindungsgemäß begrenzt wird.Another advantageous embodiment of the invention provides that the friction force is adjustable. At a low frictional force in this embodiment, a relative displacement of the first part and the second part to each other already starts at a relatively low negative acceleration of the load receiving means, while a higher frictional force, the relative movement of the first part and the second part begins only at a relatively high negative acceleration. By adjusting the friction force is thus adjustable at which negative acceleration, the means for limiting or reducing the negative acceleration of the lifting device are effective. Thus, for example, and in particular adjustable, to which value the negative acceleration is limited according to the invention.

Um die Reibflächen sicher miteinander in Eingriff zu halten, sieht eine andere vorteilhafte Weiterbildung Federmittel zum Vorspannen der Reibflächen gegeneinander vor.To securely hold the friction surfaces engaged with each other, another advantageous embodiment provides spring means for biasing the friction surfaces against each other.

Um bei der vorgenannten Ausführungsform die Reibkraft auf einfache Weise einstellen zu können, sieht eine vorteilhafte Weiterbildung der vorgenannten Ausführungsform vor, daß die Vorspannkraft der Federneinstellbar ist.In order to adjust the frictional force in a simple manner in the aforementioned embodiment, provides an advantageous development of the aforementioned embodiment, that the biasing force of the spring adjustable is.

Um einen einfachen und zugleich mechanisch robusten Aufbau zu erzielen, sieht eine andere Weiterbildung vor, daß das erste Teil Backen aufweist, zwischen denen das zweite Teil aufgenommen ist. Bei dieser Ausführungsform kann das erste Teil beispielsweise und insbesondere zwischen den Backen des zweiten Teiles eingespannt sein. In hierzu entsprechender Weise ist es auch möglich, daß das erste Teil Backen aufweist, zwischen denen das zweite Teil aufgenommen ist.In order to achieve a simple and at the same time mechanically robust construction, another development provides that the first part has jaws between which the second part is received. In this embodiment, the first part can be clamped, for example, and in particular between the jaws of the second part. In this way, it is also possible that the first part has jaws, between which the second part is received.

Eine andere vorteilhafte Weiterbildung der Erfindung sieht vor, daß die Reibflächen mittels einer Schraubvorrichtung gegeneinander verspannbar oder verspannt sind. Haben sich bei dieser Ausführungsform bei einem Notfall das erste Teil und das zweite Teil in Tragseilrichtung relativ zueinander verschoben, so kann die Hubvorrichtung wieder in ihren normalen Funktionszustand versetzt werden, indem die Schraubvorrichtung gelöst, die Teile wieder in ihre Ausgangsposition gebracht und die Schraubvorrichtung dann wieder angezogen werden.Another advantageous embodiment of the invention provides that the friction surfaces by means of a screw against each other are braced or braced. Have shifted in this embodiment, in an emergency, the first part and the second part in the supporting cable relative to each other, the lifting device can be returned to its normal operating state by the screw solved, the parts returned to their original position and the screw then again be attracted.

Eine andere vorteilhafte Weiterbildung der Erfindung sieht vor, daß eines der Teile eine in Tragseilrichtung verlaufende Führung aufweist, in oder an der das andere Teil in Tragseilrichtung geführt ist.Another advantageous embodiment of the invention provides that one of the parts has a running in the direction of the cable guide, in or on the other part is guided in the direction of the cable carrier.

Die Erfindung wird nachfolgend anhand eines Ausführungsbeispiels unter Bezugnahme auf die beigefügte Zeichnung näher erläutert. Dabei bilden alle beschriebenen, in der Zeichnung dargestellten und in den Patentansprüchen beanspruchten Merkmale für sich genommen sowie in beliebiger Kombination miteinander den Gegenstand der Erfindung, unabhängig von ihrer Zusammenfassung in den Patentansprüchen und deren Rückbeziehung sowie unabhängig von ihrer Beschreibung bzw.

In Fig. 1 ist stark schematisiert ein Ausführungsbeispiel einer erfindungsgemäßen Hubvorrichtung 2 für Lasten dargestellt, die beispielsweise dazu dienen kann, Lasten an Lagerplätzen eines Hochregallagers einzulagern bzw. die Lasten auszulagern. Die Hubvorrichtung 2 weist ein Lastaufnahmemittel 4 auf, das bei diesem Ausführungsbeispiel an vier Tragseilen aufgehängt ist, von denen in Fig. 1 lediglich eines mit dem Bezugszeichen 6 versehen ist. Die Funktion der übrigen Tragseile ist zu dem Tragseil 6 entsprechend, so daß nachfolgend ausschließlich das Tragseil 6 näher erläutert wird.In Fig. 1 is a highly schematic representation of an embodiment of a lifting device 2 according to the invention for loads shown, for example, can serve to store loads at storage bins of a high-bay warehouse or outsource the loads. The lifting device 2 has a load-receiving means 4, which is suspended in this embodiment, four suspension cables, of which in Fig. 1 only one is provided with the reference numeral 6. The function of the remaining support cables is to the support cable 6 accordingly, so that subsequently only the support cable 6 is explained in more detail.

Die Hubvorrichtung 2 weist ferner Mittel zum Auf- und Abwickeln des Tragseiles 6 zum Anheben bzw. Absenken des Lastaufnahmemittels 4 auf, die bei diesem Ausführungsbeispiel durch eine Wickeltrommel 8 gebildet ist, die mittels eines nicht dargestellten Elektromotors um eine Drehachse 10 drehantreibbar ist. Bei Benutzung werden die dem Tragseil 6 sowie den übrigen Tragseilen zugeordneten Wickeltrommeln 8 synchron drehangetrieben, so daß entsprechend der jeweiligen Drehrichtung der Wickeltrommeln 8 das Lastaufnahmemittel 4 angehoben bzw. abgesenkt wird.The lifting device 2 further comprises means for winding and unwinding of the support cable 6 for raising or lowering of the load receiving means 4, which is formed in this embodiment by a winding drum 8, which is rotationally driven about an axis of rotation 10 by means of an electric motor, not shown. In use, the carrying rope 6 and the other supporting cables associated winding drums 8 are rotated synchronously, so that according to the respective direction of rotation the winding drums 8, the load-receiving means 4 is raised or lowered.

Bei Benutzung der Hubvorrichtung 2 erfolgt das Anheben bzw. Absenken des Lastaufnahmemittels 4 mit einer hohen Geschwindigkeit von etwa 60 m/min bis etwa 120 m/min. Falls beim Anheben des Lastaufnahmemittels 4 eine Notabschaltung wirksam wird, so werden die Wickeltrommeln 8 schlagartig stillgesetzt. Aufgrund seiner Massenträgheit bewegt sich das Lastaufnahmemittel dann über ein gewisses Stück weiter aufwärts, so daß die Tragseile 6 durchhängen. Nach einem Stillstand an einem oberen Umkehrpunkt bewegt sich das Lastaufnahmemittel 4 daran anschließend wieder abwärts, wobei zu dem Zeitpunkt, zu dem die Tragseile 6 wieder gespannt sind, eine erhebliche negative Beschleunigung des Lastaufnahmemittels 4 wirkt. Um zu verhindern, daß diese negative Beschleunigung zu einer Beschädigung des Lastaufnahmemittels 4 sowie darauf angeordneter Komponenten, beispielsweise eines Kanalfahrzeugs zum Einlagern von Lasten in einem Hochregallager bzw. zum Entnehmen von Lasten aus dem Hochregallager, sowie einer auf dem Lastaufnahmemittel 4 aufgenommenen Last, führt, sind erfindungsgemäß Mittel zum Vermindern und/oder Begrenzen der negativen Beschleunigung des Lastaufnahmemittels vorgesehen. Diese Mittel weisen bei dem dargestellten Ausführungsbeispiel an jedem der Tragseile eine Vorrichtung auf, die in Fig. 1 rein schematisch dargestellt und mit dem Bezugszeichen 12 versehen ist. Die Vorrichtung 12 ist dem Tragseil 6 zugeordnet. In hierzu entsprechender Weise sind den übrigen Tragseilen entsprechende Vorrichtungen zugeordnet.When using the lifting device 2, the lifting or lowering of the lifting device 4 takes place at a high speed of about 60 m / min to about 120 m / min. If an emergency stop is effective when lifting the lifting device 4, the winding drums 8 are stopped suddenly. Due to its inertia, the load-carrying means then moves upwards over a certain distance, so that the supporting cables 6 sag. After a standstill at an upper reversal point, the load-receiving means 4 then moves downwards again, wherein at the time at which the supporting cables 6 are again tensioned, a significant negative acceleration of the load-receiving means 4 acts. In order to prevent this negative acceleration leads to damage of the lifting device 4 and arranged thereon components, such as a canal vehicle for storing loads in a high-bay warehouse or for removing loads from the high-bay warehouse, as well as a recorded on the load-carrying means 4 load, According to the invention means are provided for reducing and / or limiting the negative acceleration of the lifting device. These means have in the illustrated embodiment on each of the support cables on a device which in Fig. 1 shown purely schematically and is provided with the reference numeral 12. The device 12 is associated with the support cable 6. In a corresponding manner, the other supporting cables corresponding devices are assigned.

Fig. 1 zeigt eine Perspektivansicht der Vorrichtung 12, die bei diesem Ausführungsbeispiel ein mit dem in Fig. 2 symbolisch angedeuteten Tragseil 6 verbundenes erstes Teil 14 und ein mit dem Lastaufnahmemittel verbundenes zweites Teil 16 aufweist, die in Tragseilrichtung 6 in Richtung eines Doppelpfeiles 18 relativ zueinander verschiebbar mit Reibflächen aneinander anliegen. Fig. 1 shows a perspective view of the device 12, which in this embodiment, a with the in Fig. 2 symbolically indicated support cable 6 connected first part 14 and connected to the load receiving means second part 16 which rest in the direction of a double arrow 18 in the direction of a double arrow 18 relative to each other slidably with friction surfaces to each other.

Bei dem dargestellten Ausführungsbeispiel weist das zweite Teil 16 Backen 20, 22 auf, die an ihren dem zweiten Teil 16 zugewandten Flächen nach Art von Bremsbelägen 24, 26 ausgebildet sind. Die Bremsbeläge 24, 26 bilden Reibflächen des ersten Teiles, mit denen dasselbe an Reibflächen 28, 30 des zweiten Teiles anliegt. Bei dem dargestellten Ausführungsbeispiel weist das zweite Teil 16 eine in Tragseilrichtung verlaufende Führung 32 auf, die bei dem dargestellten Ausführungsbeispiel durch einen Schlitz gebildet ist. In der Führung 32 sind bei dem dargestellten Ausführungsbeispiel Bolzen in Form von Schraubbolzen 36, 38 geführt, die sich durch in der Backe 22 gebildete Durchgangsbohrungen erstrecken und in Gewindebohrungen eingeschraubt sind, die in der Backe 20 gebildet sind. Die Bolzen 36, 38 bilden eine Schraubvorrichtung, mittels derer die Reibflächen 28, 30 des zweiten Teiles mit den durch die Bremsbeläge 24, 26 gebildeten Reibflächen des ersten Teiles 14 verspannbar sind.In the illustrated embodiment, the second part 16 jaws 20, 22 which are formed on their the second part 16 facing surfaces in the manner of brake pads 24, 26. The brake pads 24, 26 form friction surfaces of the first part, with which the same bears against friction surfaces 28, 30 of the second part. In the illustrated embodiment, the second part 16 has a guide 32 running in the direction of the cable, which is formed by a slot in the illustrated embodiment. In the guide 32 in the illustrated embodiment, bolts in the form of bolts 36, 38 are guided, which extend through through holes formed in the jaw 22 and are screwed into threaded holes formed in the jaw 20. The bolts 36, 38 form a screw device by means of which the friction surfaces 28, 30 of the second part with the friction surfaces of the first part 14 formed by the brake pads 24, 26 are clamped.

Fig. 3 zeigt eine Seitenansicht der Vorrichtung 12. Um die Reibflächen 24, 26 und die Reibflächen 30, 32 gegeneinander vorzuspannen, sind Federmittel vorgesehen, die bei diesem Ausführungsbeispiel durch Federn 40, 42 gebildet sind, die koaxial zu den Schraubbolzen 36 bzw. 38 angeordnet sind. Fig. 3 shows a side view of the device 12. In order to bias the friction surfaces 24, 26 and the friction surfaces 30, 32 against each other, spring means are provided, which are formed in this embodiment by springs 40, 42 which are arranged coaxially to the bolts 36 and 38, respectively.

In Abhängigkeit davon, wie stark die Reibflächen 24, 26 und die Reibflächen 28, 30 mittels der Schraubbolzen 36, 38 verspannt sind und wie die Federkonstante der Federn 40, 42 gewählt ist, wirkt zwischen den Reibflächen 24, 26 und den Reibflächen 28, 30 eine unterschiedliche starke Reibkraft.Depending on how strong the friction surfaces 24, 26 and the friction surfaces 28, 30 are clamped by means of the bolts 36, 38 and how the spring constant of the springs 40, 42 is selected, acts between the friction surfaces 24, 26 and the friction surfaces 28, 30 a different strong friction force.

Die Funktionsweise der erfindungsgemäßen Hubvorrichtung 2 ist wie folgt:

  • Bei Betrieb werden mittels der Hubvorrichtung 2 Lasten transportiert, wobei die Hubvorrichtung 2 durch entsprechendes Drehantreiben der Wickeltrommeln 8 angehoben oder abgesenkt wird. Auf diese Weise ist eine Bewegung des Lastaufnahmemittels 4 entlang einer vertikalen Hubachse realisiert. Eine Bewegung des Lastaufnahmemittels 4 in einer zu der Hubachse senkrechten Ebene kann dadurch realisiert sein, daß die Hubvorrichtung 2 an einer in einer Ebene verfahrbaren Krankatze oder dergleichen angeordnet ist.
The operation of the lifting device 2 according to the invention is as follows:
  • In operation, 2 loads are transported by means of the lifting device, wherein the lifting device 2 is raised or lowered by appropriate Drehantreiben the winding drums 8. In this way, a movement of the load-receiving means 4 is realized along a vertical lifting axis. A movement of the load-receiving means 4 in a plane perpendicular to the lifting axis can be realized in that the lifting device 2 is arranged on a movable in a plane trolley or the like.

Bei einer Notabschaltung der Hubvorrichtung 2 während einer schnellen Aufwärtsbewegung des Lastaufnahmemittels 4 bewegt sich dieses aufgrund seiner Massenträgheit zunächst über ein kurzes Stück weiter aufwärts, wobei die Tragseile 6 nicht mehr gespannt sind. Daran anschließend bewegt sich das Lastaufnahmemittel 4 abwärts.In an emergency shutdown of the lifting device 2 during a rapid upward movement of the lifting device 4, this moves due to its inertia initially over a short distance further up, the support cables 6 are no longer curious. Subsequently, the load-receiving means 4 moves downwards.

Wirkt dann, wenn die Tragseile 6 wieder gespannt sind, das Lastaufnahmemittel also in die Tragseile 6 zurückfällt, eine negative Beschleunigung auf das Lastaufnahmemittel 4, die größer ist als eine maximal zulässige negative Beschleunigung, so treten die vorrichtungen 12 in Funktion. Ist die auf das Lastaufnahmemittel 4 wirkende negative Beschleunigung so groß, daß die Reibkraft zwischen den Reibflächen 24, 26 und 28, 30 überwunden wird, so verschiebt sich das zweite Teil 16 in Tragseilrichtung relativ zu dem ersten Teil 14, wobei die Schraubbolzen 36, 38 in der Führung 32 geführt sind und die Reibflächen 26, 28 sowie die Reibflächen 24, 30 aneinander reiben. Da die Reibflächen 24, 26 nach Art von Bremsbelägen ausgebildet sind, wird hierbei die kinetische Energie des Lastaufnahmemittels 4 wenigstens teilweise in Wärme umgewandelt, bis die Beschleunigung des Lastaufnahmemittels 4 so gering ist, daß die Reibkraft zwischen den Reibflächen 26, 28 bzw. 24, 30 nicht mehr überwunden wird. Im Ergebnis wird das Lastaufnahmemittel 4 damit während seiner Abwärtsbewegung abgebremst, wobei die negative Beschleunigung des Lastaufnahmemittels 4 auf ein Maß begrenzt ist, bei dem eine Beschädigung des Lastaufnahmemittels 4 sowie daran angeordneter Komponenten vermieden ist.If the suspension cables 6 are tensioned again, that is, the load suspension device falls back into the suspension cables 6, a negative acceleration on the load suspension device 4, which is greater than a maximum permissible negative acceleration, then the devices 12 come into operation. If the negative acceleration acting on the load-receiving means 4 is so great that the frictional force between the friction surfaces 24, 26 and 28, 30 is overcome, the second part 16 shifts in the direction of the carrying cable relative to the first part 14, wherein the threaded bolts 36, 38 are guided in the guide 32 and the friction surfaces 26, 28 and the friction surfaces 24, 30 rub against each other. Because the friction surfaces 24, 26 are formed in the manner of brake pads, in this case the kinetic energy of the load receiving means 4 is at least partially converted into heat until the acceleration of the load receiving means 4 is so low that the friction between the friction surfaces 26, 28 and 24, 30 no longer is overcome. As a result, the load-receiving means 4 is thus braked during its downward movement, wherein the negative acceleration of the load-receiving means 4 is limited to a level at which damage to the load-receiving means 4 and arranged thereon components is avoided.

Durch die erfindungsgemäß vorgesehenen Mittel zum Vermindern und/oder Begrenzen einer negativen Beschleunigung des Lastaufnahmemittels 4 ist somit die Betriebssicherheit der Hubvorrichtung 2 wesentlich erhöht.By the inventively provided means for reducing and / or limiting a negative acceleration of the load receiving means 4 thus the reliability of the lifting device 2 is substantially increased.

Die Figuren 2 und 3 stellen die Teile 14, 16 relativ zueinander in einer Position dar, die ihrer normalen Betriebsposition entspricht. Hat sich bei einer Notabschaltung das zweite Teil 16 relativ zu dem ersten Teil 14 in Fig. 2 bzw. 3 nach unten bewegt, so können die Schraubbolzen 30, 38 gelöst und die Teile wieder in die in den Figuren 2 und 3 dargestellte Position gebracht werden. In dieser Betriebsposition können die Schraubbolzen 36, 38 dann wieder angezogen werden.The Figures 2 and 3 represent the parts 14, 16 relative to each other in a position corresponding to their normal operating position. Has in an emergency shutdown, the second part 16 relative to the first part 14 in Fig. 2 or 3 moves down, so the bolts 30, 38 can be solved and the parts back into the in the Figures 2 and 3 shown position. In this operating position, the bolts 36, 38 can then be tightened again.

Anstelle der in den Figuren 2 und 3 dargestellten Vorrichtung 12 können erfindungsgemäß auch beliebige andere Mittel verwendet werden, die zum Vermindern und/oder Begrenzen einer negativen Beschleunigung des Lastaufnahmemittels geeignet sind, beispielsweise pro Tragseil eine Feder/Dämpfer-Kombination. Die in den Figuren 2 und 3 dargestellte Vorrichtung 12 hat jedoch den Vorteil eines einfachen, kostengünstigen und robusten Aufbaus.Instead of in the Figures 2 and 3 12 may be used according to the invention also any other means which are suitable for reducing and / or limiting a negative acceleration of the lifting device, for example, per suspension rope a spring / damper combination. The in the Figures 2 and 3 However, device 12 shown has the advantage of a simple, inexpensive and robust construction.
