Description

Die Erfindung betrifft eine Seilführung für ein Windwerk, insbesondere ein Hubwerk, mit einer gegenläufige Seilrillen aufweisenden und in einem Rahmen drehgelagerten Windentrommel, mit an zumindest einer Schiene parallel zur Drehachse der Windentrommel verfahrbaren und zur Ausrichtung von zumindest einem Paar Seilstränge in bezug auf die zugeordnete Seilrille vorgesehenen Führungsmitteln, die über Kopplungsmittel gegenläufig miteinander verbunden und von den aufwickelbaren oder abwickelbaren Seilsträngen antreibbar sind und Führungselemente aufweisen, wobei die Schiene quer zur Drehachse der Windentrommel um eine parallel zur Drehachse der Windentrommel verlaufende Schwenkachse verschwenkbar am Windwerk angeordnet ist.The invention relates to a cable guide for a winch, in particular a hoist, with counter-rotating rope grooves and rotatably mounted in a frame Winch drum, with at least one rail parallel to the axis of rotation of the Winch drum movable and for aligning at least one pair Rope strands in relation to the associated rope groove provided guide means that connected in opposite directions via coupling means and of the windable or unwindable rope strands can be driven and have guide elements, the rail transverse to the axis of rotation of the winch drum parallel to the The axis of rotation of the winch drum is pivotable on the pivot axis Windwork is arranged.

Derartige Seilführungen werden an Windwerken eingesetzt, die insbesondere Windentrommeln mit Seilrillen aufweisen, um eine Überschreitung der zulässigen seitlichen Ablenkung der Hubseile längs zur Drehachse der Windentrommel zu verhindern; diese Ablenkungen treten beispielsweise durch Pendeln der Last oder Schrägzug auf. Erfahrungsgemäß führt eine Verkleinerung der daraus resultierenden Ablenkungen zu einer Erhöhung der Aufliegezeit der Seile.Such rope guides are used on wind turbines, in particular Have winch drums with rope grooves to exceed the permissible lateral deflection of the hoisting ropes along the axis of rotation of the winch drum prevent; these distractions occur, for example, by swinging the load or Diagonal pull on. Experience has shown that the resulting result is reduced Distractions to increase the rope lay time.

Aus der DE 42 41 655 C1 ist eine gattungsgemäße Seilführung bekannt, bei der eine Schiene einschließlich der Führungselemente in unmittelbarer Nähe zu den tangentialen Ablaufpunkten der Seilstränge von der Windentrommel schwenkbar aufgehängt ist, was eine weitestgehende Anpassung der Schwenkbewegung der Schiene einschließlich der Führungselemente an die Auslenkbewegung der Seilstränge quer zur Drehachse der Windentrommel ermöglicht, wodurch eine besonders schonende antriebslose Führung der Seilstränge erzielt wird. Diese Seilführung ist robust und erfordert konstruktiv nur einen relativ geringen Aufwand; aufgrund der Verwendung von kugelgelagerten Führungsrollen ist die Robustheit, Schlagfestigkeit und Wartungsfreiheit jedoch begrenzt. Ferner ermöglichen die Führungsrollen nur eine begrenzte Anpassung der Seilführung an die unterschiedlichen Anforderungen oberhalb und unterhalb der Seilführung.From DE 42 41 655 C1 a generic rope guide is known in which one Rail including the guide elements in close proximity to the tangential run-off points of the rope strands can be swiveled by the winch drum is suspended, which is an extensive adjustment of the pivoting movement of the Rail including the guide elements to the deflection movement of the Rope strands transverse to the axis of rotation of the winch drum allows, thereby a particularly gentle drive-free guidance of the rope strands is achieved. This Rope guidance is robust and requires only a relatively small amount of construction work; due to the use of ball bearing guide rollers, the robustness, Impact resistance and freedom from maintenance are however limited. Furthermore, the Guide rollers only a limited adjustment of the rope guide to the different requirements above and below the rope guide.

Der Erfindung liegt die Aufgabe zugrunde, eine antriebslose Seilführung für ein Windwerk, insbesondere ein Hubwerk, zu schaffen, die ein schonendes Auf- oder Abwickeln des Seiles, insbesondere auch bei Schrägzug des Seiles, ermöglicht, gleichzeitig eine kompakte Bauform aufweist und dabei robust, schlagfest und wartungsfrei ist. Außerdem sollte die Seilführung besser an die unterschiedlichen Anforderungen oberhalb und unterhalb der Seilführung anpaßbar sein.The invention has for its object a drive-free cable guide for a Windwork, in particular a hoist, to create a gentle up or down Unwinding of the rope, especially when the rope is pulled at an angle, at the same time has a compact design and is robust, impact-resistant and is maintenance free. In addition, the rope guide should better match the different Requirements can be adapted above and below the rope guide.

Lösungen dieser Aufgabe sind erfindungsgemäß gekennzeichnet durch die in den Patentansprüchen 1 und 11 angegebenen Merkmale. Durch die kennzeichnenden Merkmale der Unteransprüche 2 bis 10 bzw. 12 bis 16 ist die Seilführung in vorteilhafter Weise weiter ausgestaltbar.Solutions to this problem are characterized in accordance with the invention in the Claims 1 and 11 specified features. By the characteristic Features of subclaims 2 to 10 and 12 to 16 is the cable guide in can be further configured in an advantageous manner.

Erfindungsgemäß umfassen die Führungselemente jeweils einen in einem Kanalträger ausgebildeten Seilführungskanal, der in einer ersten Ebene senkrecht zur Drehachse der Windentrommel einen Eingangsanlageabschnitt für ein Seil und einen gegenüberliegenden Ausgangsanlageabschnitt für das Seil und der in einer zweiten Ebene parallel zur Drehachse der Windentrommel einen Eingangsanlageabschnitt für. das Seil und einen gegenüberliegenden Ausgangsanlageabschnitt für das Seil aufweist, so daß der Seilstrang durch den zugeordneten Seilführungskanal für verschiedene Abzugswinkel des Seils bezogen auf den Wickelumfang der Windentrommel jeweils tangential geführt ist. Damit wird eine Erhöhung der Robustheit, der Schlagfestigkeit und der Wartungsfreiheit (keine Kugellager) erzielt. Darüber hinaus läßt sich durch entsprechende Gestaltung der Eingangsanlageabschnitte und der Ausgangsanlageabschnitte die Seilführung besser an die unterschiedlichen Führungsanforderungen, beispielsweise oberhalb und unterhalb der Führung, anpassen. So ist es beispielsweise möglich, den Eingangsanlageabschnitt schmaler auszuführen als den Ausgangsanlageabschnitt, und dies sogar in der Art und Weise, daß die Abschnitte in der ersten und zweiten Ebene unterschiedlich oder sogar gegensätzlich ausbildbar sind. Darüber hinaus ermöglicht die erfindungsgemäße Lösung der Aufgabe eine deutliche Vereinfachung des Führungselements und damit eine Verringerung des Herstellungsaufwandes.According to the invention, the guide elements each include one in a channel carrier trained cable guide channel, which is perpendicular to the axis of rotation in a first plane the winch drum an input system section for a rope and opposite exit section for the rope and that in a second Plane parallel to the axis of rotation of the winch drum an input system section for. the rope and an opposite exit section for the rope has, so that the rope strand through the associated rope guide channel for different withdrawal angles of the rope related to the circumference of the winding Winch drum is guided tangentially. This will increase the Robustness, impact resistance and freedom from maintenance (no ball bearings) achieved. In addition, by appropriate design of the Input system sections and the output system sections better the rope guide to the different management requirements, for example above and below the guide, adjust. For example, it is possible Entrance section to be made narrower than the exit section, and even in the way that the sections in the first and second Level can be trained differently or even oppositely. Furthermore enables the solution of the task a clear simplification of the guide element and thus a reduction in manufacturing costs.

Mit der Erfindung wird vorgeschlagen, daß der Eingangsanlageabschnitt und der Ausgangsanlageabschnitt der korrespondierenden Ebene unmittelbar aufeinanderfolgend angeordnet sind; beide Abschnitte gehen folglich kontinuierlich ineinander über, wodurch eine gute Anlage des Seiles an zwei sich gegenüberliegenden Seitenflächen erzielt wird, was wiederum eine genaue und schonende Führung des Seils ermöglicht.With the invention it is proposed that the input system section and Exit plant section of the corresponding level immediately are arranged in succession; consequently, both sections go continuously into each other, which allows the rope to attach itself well to two opposite side faces is obtained, which in turn is accurate and gentle rope guidance.

Insbesondere wird eine gute Führung des Seils dadurch erzielt, daß der Seilführungskanal derart ausgebildet ist, daß der geführte Seilstrang auf einer Seite der jeweiligen Eingangsanlageabschnitte und auf einer Seite der jeweiligen Ausgangsanlageabschnitte anliegt.In particular, good guidance of the rope is achieved in that the Cable guide channel is designed such that the guided rope strand on one side of the respective input system sections and on one side of the respective Output plant sections is present.

Besonders günstig ist es hinsichtlich der Seilführung, wenn die der Windentrommel zugewandten Fläche des Eingangsanlageabschnitts und die der Windentrommel abgewandten Fläche des Ausgangsanlageabschnitts im wesentlichen parallel zueinander ausgebildet sind, was insbesondere auch bei senkrechtem Seilzug nach unten eine gute Führung des Seils ermöglicht.It is particularly favorable with regard to the cable guide if the winch drum facing surface of the input system section and that of the winch drum facing away surface of the exit section substantially parallel are formed to each other, which is particularly true even with a vertical cable pull allows good rope routing at the bottom.

Um auch bei großem Abzugswinkel quer zur Drehachse der Windentrommel das Seil sicher zu führen, wird vorgeschlagen, daß die der Windentrommel abgewandte Fläche des Eingangsanlageabschnitts und die der Windentrommel zugewandte Fläche des Ausgangsanlageabschnitts im wesentlichen parallel zueinander ausgebildet sind.Around the rope even with a large take-off angle transverse to the axis of rotation of the winch drum to safely guide it is proposed that the surface facing away from the winch drum of the input system section and the surface of the winch drum facing the Output plant section are formed substantially parallel to each other.

Um die Unsymmetrie der Belastungen besser zu berücksichtigen, wird vorgeschlagen, daß der Seilführungskanal derart ausgebildet ist, daß der geführte Seilstrang in der zweiten Ebene parallel zur Drehachse der Windentrommel im Eingangsanlageabschnitt und im Ausgangsanlageabschnitt auf derselben Fläche anliegt. In order to take better account of the asymmetry of the loads, it is proposed that that the cable guide channel is designed such that the guided rope strand in the second level parallel to the axis of rotation of the winch drum in Inlet section and in the outlet section on the same area is applied.

Eine ruhige Führung des Seils wird erzielt, wenn der Seilführungskanal im mittleren Bereich seinen kleinsten Querschnitt hat, der zum Eingang und Ausgang hin wieder zunimmt. Der Seilführungskanal ist also bildlich gesprochen mit einer Taille versehen, die eine "fokussierende" Wirkung hinsichtlich der Lage des Seils hat, was zu einer Beruhigung von Seilschwingungen führt. Dadurch muß sich außerdem die Schwenkachse der Seilführung nicht mehr in Höhe der Drehachse der Windentrommel befinden. Der zwangsläufig auftretende schräge Durchlauf des Drahtseiles wird durch die spezielle Ausbildung der Form des Seilführungskanals nicht behindert.A smooth guidance of the rope is achieved if the rope guide channel in the middle Area has its smallest cross-section, that towards the entrance and exit again increases. The rope guide channel is therefore figuratively provided with a waist, which has a "focusing" effect on the position of the rope, resulting in a Calming of rope vibrations leads. This also means that Swivel axis of the cable guide no longer at the level of the axis of rotation of the winch drum are located. The inevitable oblique passage of the wire rope is through the special design of the shape of the cable guide channel is not hindered.

Den unterschiedlichen Anforderungen wird der Seilführungskanal dadurch gerecht, daß der Querschnitt des Seilführungskanals in der zweiten Ebene parallel zur Drehachse der Windentrommel zum Eingang hin um einen Wert zunimmt, der kleiner als der Querschnitt des Seils ist. Die im oberen Teil nahezu parallele Kontur führt zu einer großflächigen Abstützung des Seiles und dadurch zu einem großen Verschleißvolumen und sehr günstige Reibbedingungen in der Hauptbelastungsrichtung.The cable guide channel meets the different requirements that the cross section of the cable guide channel in the second plane parallel to The axis of rotation of the winch drum increases towards the entrance by a value that is smaller than the cross section of the rope. The almost parallel contour in the upper part leads to a large-scale support of the rope and thereby a large one Wear volume and very favorable friction conditions in the Main load direction.

Ferner wird vorgeschlagen, daß der Querschnitt des Seilführungskanals in der zweiten Ebene parallel zur Drehachse der Windentrommel zum Ausgang hin symmetrisch zur Symmetrieachse des Seilführungskanals zunimmt. Die stark gekrümmte untere Kontur ermöglicht große vorgebbare Krümmungsradien, ohne daß bedingt z.B. durch große Führungsrollen der Abstand der von der Seiltrommel ablaufenden Seile zu groß wird.It is also proposed that the cross section of the cable guide channel in the second Plane parallel to the axis of rotation of the winch drum towards the exit symmetrical to Axis of symmetry of the cable guide channel increases. The strongly curved lower contour enables large predefinable radii of curvature without conditionally e.g. by great Guide rollers the distance between the cables running from the cable drum becomes too large.

Der Verschleiß und die Belastung des Seils durch den Seilführungskanal läßt sich dadurch verringern, daß die Querschnittslinie des Seilführungskanals in der zweiten Ebene parallel zur Drehachse der Windentrommel im Ausgangsanlageabschnitt zum Ausgang hin bogenförmig mit zunehmendem Biegeradius ausgebildet ist.The wear and the load on the rope through the rope guide channel can be thereby reduce that the cross-sectional line of the cable guide channel in the second Plane parallel to the axis of rotation of the winch drum in the exit system section for Output is arched with increasing bending radius.

Die Seilführung für ein Windwerk, insbesondere ein Hubwerk, mit einer gegenläufige Seilrillen aufweisenden und in einem Rahmen drehgelagerten Windentrommel mit an zumindest einer Schiene parallel zur Drehachse der Windentrommel verfahrbaren und zur Ausrichtung von zumindest einem Paar Seilstränge in bezug auf die zugeordnete Seilrille vorgesehenen Führungsmitteln, die über Kopplungsmittel gegenläufig miteinander verbunden und von den aufwickelbaren oder abwickelbaren Seilsträngen antreibbar sind und Führungselemente aufweisen, wobei die Schiene quer zur Drehachse der Windentrommel um eine parallel zur Drehachse der Windentrommel verlaufende Schwenkachse verschwenkbar am Windwerk angeordnet ist, läßt sich konstruktiv sehr einfach und mit nur geringem Aufwand herstellen, wenn die Führungselemente jeweils einen in einem Kanalträger ausgebildeten Seilführungskanal umfassen, daß der Kanalträger aus zwei gleichen aneinanderliegenden Trägerhälften besteht und daß in den aneinanderliegenden Seitenflächen der Trägerhälften jeweils ein halber Seilführungskanal derart ausgebildet ist, daß das Seil nahezu biegungsfrei geführt ist in der die Trägerhälften trennenden Trennebene, die jeweils in der Schwenkebene oder parallel zu dieser liegt. Damit wird weiter eine Erhöhung der Robustheit, der Schlagfestigkeit und der Wartungsfreiheit (keine Kugellager) bei schonender Seilführung erzielt. Darüber hinaus läßt sich die Seilführung durch den mechanisch einfach herstellbaren Seilführungskanal nahezu beliebig an die unterschiedlichen Führungsanforderungen, beispielsweise oberhalb und unterhalb der Führung, anpassen. Darüber hinaus ermöglicht die erfindungsgemäße Lösung der Aufgabe eine deutliche Vereinfachung des Führungselements und damit eine Verringerung des Herstellungsaufwandes.The cable guide for a winch, in particular a hoist, with an opposing one Winch drum with rope grooves and rotatably mounted in a frame at least one rail movable parallel to the axis of rotation of the winch drum and for aligning at least one pair of rope strands with respect to the associated one Rope groove provided guide means that counter-coupling means connected to each other and from the windable or unwindable rope strands are drivable and have guide elements, the rail transverse to The axis of rotation of the winch drum is parallel to the axis of rotation of the winch drum extending pivot axis is pivotally arranged on the winch, can constructively very simple and with little effort if the Guide elements each formed in a channel support Rope guide channel include that the channel carrier made of two of the same adjacent halves of the support and that in the adjacent Side surfaces of the carrier halves each formed half a cable guide channel is that the rope is guided almost without bending in the separating the support halves Separation plane, which is in the swivel plane or parallel to it. So that will further increase in robustness, impact resistance and freedom from maintenance (no ball bearings) achieved with gentle rope guidance. In addition, the Rope guidance through the mechanically easy to manufacture rope guide channel almost any of the different management requirements, for example above and below the guide, adjust. In addition, the Solution according to the invention a significant simplification of the Guide element and thus a reduction in manufacturing costs.

Von Vorteil ist es insbesondere, wenn die Seitenflächen, die den aneinanderliegenden Seitenflächen der Trägerhälften jeweils gegenüberliegen, parallel zueinander ausgebildet und zusätzlich mit einem halben Seilführungskanal versehen sind, wenn also ein halber Seilführungskanal in diese Seitenfläche eingeformt ist. Damit ist es möglich, Trägerhälften mit verschlissenem Seilführungskanal dadurch zu erneuern, daß die Trägerhälften einfach seitenvertauscht wieder fest miteinander verbunden werden; man kann die Trägerhälften auf diese Weise doppelt so lange nutzen.It is particularly advantageous if the side faces that are adjacent to one another Side faces of the support halves are opposite each other, parallel to each other trained and additionally provided with a half cable guide channel, if half a cable guide channel is formed in this side surface. So that's it possible to replace beam halves with a worn cable guide channel, that the carrier halves simply swapped sides firmly connected again become; you can use the carrier halves twice as long in this way.

Konstruktiv ist es von Vorteil, wenn der aus zwei Trägerhälften bestehende Kanalträger quer zur Kanallängsachse mit einer fluchtenden Nut versehen ist, in die ein Verbindungselement formschlüssig eingesetzt ist und daß das Verbindungselement mit den beiden Trägerhälften verbunden ist, was die Stabilität der verbundenen Trägerhälften verbessert. In terms of design, it is advantageous if the beam consists of two beam halves Channel carrier is provided transversely to the longitudinal axis of the channel with an aligned groove into which a connecting element is positively inserted and that Connecting element is connected to the two support halves, which the stability of the connected carrier halves improved.

Darüberhinaus wird eine weitere verdrehsichere Verbindung der Trägerhälften dadurch erreicht, daß die Trägerhälften jeweils mit einem Nocken versehen sind, der formschlüssig in eine komplementäre Vertiefung der Führungsmittel eingreift.In addition, a further torsion-proof connection of the carrier halves is thereby achieved that the carrier halves are each provided with a cam, the engages positively in a complementary recess of the guide means.

Hinsichtlich der Gleiteigenschaften ist es von Vorteil, wenn der Kanalträger aus einem weicheren Material als das Seil ausgeführt ist.With regard to the sliding properties, it is advantageous if the channel carrier consists of one softer material than the rope.

Um Beschädigungen der auf der Windentrommel aufgewickelten Drahtseile während des Betriebes zu vermeiden, ist die der Windentrommel zugewandte Kante des Kanalträgers mit einer Abschrägung versehen.To prevent damage to the wire rope wound on the winch drum during To avoid operation, the edge of the winch drum facing the Channel holder with a bevel.

In Fig. 1 is a side view of a cable guide 1 for a hoist with both ends shown in a frame (not shown) rotatably mounted winch drum 2. The Winch drum 2 has two opposite rope grooves, not shown, each for one Rope 3 of a rope 4. The rope 4 or the rope strand 3 is at its beginning attached in the area of one end of the winch drum 2, runs from there through Rope grooves led to the winch drum 2 towards the center and leaves depending on Winding condition of the winch drum 2 at a point designated as the run-off point.

Anschließend läuft der Seilstrang 3 frei und wird dann von einem Seilführungskanal 5 geführt, der in einem Kanalträger 6 ausgebildet und Bestandteil eines Führungselements 7 ist. Nach Verlassen des Führungskanals 5 verläuft der Seilstrang 3 in Richtung einer Unterflasche (nicht gezeigt). Der aus der Unterflasche austretende Seilstrang wird in umgekehrter Reihenfolge zurück zum anderen Ende der Windentrommel 2 geführt. Die paarweise vorhandene Führungselemente 7 sind über Kopplungsmittel (nicht gezeigt) derart miteinander verbunden, daß sie nur gemeinsam, jedoch in entgegengesetzter Richtung auf einer Schiene 8 parallel zur Drehachse der Windentrommel 2 verfahrbar sind; die Schiene 8 ist quer zur Drehachse der Windentrommel 2 um eine parallel zur Drehachse der Windentrommel 2 verlaufende Schwenkachse 12 verschwenkbar am Windwerk aufgehängt. Die Schwenkachse 12 ist im Bereich der Enden der Windentrommel 2 am Rahmen angeordnet; in diesen Bereichen befindet sich der nicht benutzte Teil des aufgewickelten Seiles 4.The rope strand 3 then runs freely and is then guided by a rope guide channel 5 out, which is formed in a channel support 6 and part of a Guide element 7 is. After leaving the guide channel 5, the rope strand runs 3 towards a bottom block (not shown). The one emerging from the bottom block Rope will go back to the other end of the rope in reverse order Winch drum 2 out. The pair of guide elements 7 are over Coupling means (not shown) connected to one another in such a way that they only work together, however in the opposite direction on a rail 8 parallel to the axis of rotation of the Winch drum 2 are movable; the rail 8 is transverse to the axis of rotation of the Winch drum 2 around a parallel to the axis of rotation of the winch drum 2 Swivel axis 12 pivotally suspended on the winch. The pivot axis 12 is arranged in the region of the ends of the winch drum 2 on the frame; in these Areas of the unused part of the wound rope 4.

Fig. 1 läßt den Querschnitt des Seilführungskanals 5 in einer Ebene senkrecht zur Drehachse der Windentrommel 2 erkennen; dieser weist oben einen Eingangsanlageabschnitt 5a für das Seil 3 und unten einen gegenüberliegenden Ausgangsanlageabschnitt 5b für das Seil 3 auf, die - wie Fig. 2 besser erkennen läßt - unmittelbar ineinander übergehen. Dabei lassen Fig. 1 als auch Fig. 2 und Fig. 3 erkennen, daß das Seil 3 unabhängig von der Seilabzugsrichtung, die sich in allen drei Figuren unterscheidet, im Eingangsanlageabschnitt 5a auf der rechten Seite und im Ausgangsanlageabschnitt 5b auf der linken Seite des Seilführungskanals 5 anliegt. Dabei sind die der Windentrommel 2 zugewandte Fläche des Eingangsanlageabschnittes 5a und die der Windentrommel 2 abgewandte Fläche des Ausgangsanlageabschnittes 5b parallel zueinander ausgebildet, d. h. zumindest im Berührungsbereich des anliegenden Seiles 3 sind die Flächen zueinander parallel. Weiter sind auch die der Windentrommel 2 abgewandte Fläche des Eingangsanlageabschnittes 5a und die der Windentrommel 2 zugewandte Fläche des Ausgangsanlageabschnittes 5b im wesentlichen parallel zueinander ausgebildet. Der Seilführungskanal 5 hat im mittleren Bereich seinen kleinsten Querschnitt; zum Eingang und Ausgang hin nimmt der Querschnitt kontinuierlich zu.Fig. 1 leaves the cross section of the cable guide channel 5 in a plane perpendicular to Recognize the axis of rotation of the winch drum 2; this has one at the top Input system section 5a for the cable 3 and an opposite one below Output system section 5b for the rope 3, which - as can be seen better in FIG. 2 - merge directly into one another. 1 and also FIGS. 2 and 3 recognize that the rope 3 regardless of the direction of pull that is in all three Figures differs, in the input system section 5a on the right and in Output contact section 5b rests on the left side of the cable guide channel 5. The surface of the winch drum 2 facing Input system section 5a and the surface of the winch drum 2 facing away Output plant section 5b formed parallel to each other, i. H. at least in The contact area of the adjacent rope 3, the surfaces are parallel to each other. Furthermore, the surface of the winch drum 2 facing away Input system section 5a and the surface of the winch drum 2 facing Output system section 5b formed substantially parallel to each other. The Cable guide channel 5 has its smallest cross-section in the middle area; to the The cross section increases continuously at the entrance and exit.

In Fig. 4 ist ein Querschnitt des Kanalträgers 6 dargestellt (entspricht einer Ebene parallel zur Drehachse der Windentrommel 2). Wie Fig. 4 zeigt, weist der Seilführungskanal 5 in einer Ebene parallel zur Drehachse der Windentrommel 2 einen Eingangsanlageabschnitt 5c und einen gegenüberliegenden Ausgangsanlageabschnitt 5d für das Seil 3 auf; auch hier in dieser Querschnittsebene ist sicher gestellt, daß der Seilstrang 3 für verschiedene Abzugswinkel des Seils 3 bezogen auf den Wickelumfang der Windentrommel 2 jeweils tangential geführt ist. Der Eingangsanlageabschnitt 5c und der Ausgangsanlageabschnitt 5d gehen unmittelbar kontinuierlich ineinander über. In Fig. 4 liegt der geführte Seilstrang aufgrund der Querschnittsform des Seilführungskanals 5 in dieser Ebene auf der linken Seite des Eingangsanlageabschnittes 5c und als auch auf der linken Seite des Ausgangsanlageabschnittes 5d an, d. h. die Querschnittsform des Seilführungskanals in dieser Ebene stellt sicher, daß das Seil 3 jeweils auf derselben Seite (hier die linke Seite) anliegt. Bei Betrieb der Seilführung gleitet der Seilstrang 3 an derselben durchgehenden Fläche anliegend durch den Seilführungskanal 5. Nach oben, zum Eingang hin, nimmt der Querschnitt des Seilführungskanals 5 vom kleinsten Querschnittswert im mittleren Bereich ausgehend um einen Wert zu, der kleiner als der Querschnitt des Seils 3 ist. Zum Ausgang hin nimmt der Querschnitt des Seilführungskanals 5 symmetrisch zur Symmetrieachse 13 zu, wobei die Querschnittslinie 14 des Seilführungskanals 5 zum Ausgang hin bogenförmig mit zunehmendem Biegeradius R ausgebildet ist.4 shows a cross section of the channel support 6 (corresponds to a plane parallel to the axis of rotation of the winch drum 2). 4 shows, the Rope guide channel 5 in a plane parallel to the axis of rotation of the winch drum 2 Input system section 5c and an opposite output system section 5d for the rope 3; here too in this cross-sectional plane it is ensured that the Rope 3 for different withdrawal angles of the rope 3 based on the Winding circumference of the winch drum 2 is guided tangentially. The Inlet section 5c and outlet section 5d go immediately continuously into each other. In Fig. 4, the guided rope strand is due to the Cross-sectional shape of the cable guide channel 5 in this plane on the left side of the Input system section 5c and on the left side of the Output plant section 5d, i. H. the cross-sectional shape of the cable guide channel in this plane ensures that the rope 3 is always on the same side (here the left Side). When operating the cable guide, the cable strand 3 slides on the same continuous surface adjacent through the cable guide channel 5. Up to At the entrance, the cross section of the cable guide channel 5 is the smallest Cross-sectional value in the middle area increases by a value that is less than is the cross section of the rope 3. The cross section of the Cable guide channel 5 symmetrical to the axis of symmetry 13, the Cross-sectional line 14 of the cable guide channel 5 towards the exit with an arc increasing bending radius R is formed.

Die Führungselemente 7 bestehen aus Kanalträgern 6, die zweistückig aus zwei gleichen aneinanderliegenden Trägerhälften 6a, 6b ausgebildet sind, in deren jeweils aneinanderliegenden Seitenflächen 15, 16 ein halber Seilführungskanal 5 ausgebildet ist, und zwar so, daß das Seil 4 in der die Trägerhälften 6a, 6b trennenden Trennebene nahezu biegungsfrei geführt ist. Diese Trennebene liegt jeweils in der Schwenkebene oder zumindest parallel zu dieser. Zusätzlich sind die den aneinander anliegenden Seitenflächen 15, 16 der Trägerhälften 6a, 6b jeweils gegenüberliegenden Seitenflächen 16, 17 mit einem halben Seilführungskanal 5 versehen.The guide elements 7 consist of channel supports 6, which consist of two pieces the same abutting support halves 6a, 6b are formed, in their respective half side cable guide channel 5 is formed on adjacent side surfaces 15, 16 is so that the rope 4 in the separating the support halves 6a, 6b Parting plane is guided almost bend-free. This dividing plane lies in the Swivel plane or at least parallel to this. In addition, they are each other adjacent side surfaces 15, 16 of the carrier halves 6a, 6b each opposite side surfaces 16, 17 with half a cable guide channel 5 Mistake.

Die Fig. 5 zeigt, daß der Kanalträger 6 mit einer fluchtenden Nut 18 versehen, in die ein Verbindungselement 19 formschlüssig eingesetzt und mit mittels Schrauben 20 fest mit den beiden Trägerhälften 6a, 6b verbunden ist. Zusätzlich sind an den Trägerhälften 6a, 6b Nocken 21 befestigt, die - wie Fig. 1 zeigt - in eine komplementäre Vertiefung des Führungselementes 7 zur Erzeugung einer verdrehgegesicherten Verbindung eingreift. Zweckmäßigerweise weist der Kanalträger 6 an der der Windentrommel 2 zugewandten Kante eine Abschrägung 22 auf (Fig. 1 bis 3). Diese verläuft bei Anlage an das Seil 4 im wesentlichen parallel zur Tangentialebene der Außenfläche der Windentrommel 2 im Anlagepunkt der Abschrägung 22.Fig. 5 shows that the channel support 6 is provided with an aligned groove 18 in the a connecting element 19 is inserted in a form-fitting manner and by means of screws 20 is firmly connected to the two support halves 6a, 6b. In addition, the Carrier halves 6a, 6b attached cam 21, which - as shown in Fig. 1 - in a complementary recess of the guide element 7 to produce a interlocking connection engages. The channel carrier expediently points 6 on the edge facing the winch drum 2, a bevel 22 (FIG. 1 to 3). When running against the rope 4, this runs essentially parallel to Tangential plane of the outer surface of the winch drum 2 in the contact point Bevel 22.

Hinsichtlich der Gleiteigenschaften ist es von Vorteil, wenn der Kanalträger 6 aus einem weicheren Material als das Seil 4 ausgeführt ist. Hierfür kommen Kunststoff, insbesondere Polyamid, als auch relativ weiche Metalle, insbesondere Aluminium, in Betracht. With regard to the sliding properties, it is advantageous if the channel carrier 6 is made of a softer material than the rope 4. For this come plastic, especially polyamide, as well as relatively soft metals, especially aluminum, in Consideration.
