Description

Die Erfindung betrifft eine Seilführung für ein Windwerk gemäß dem Oberbegriff von Anspruch 1, 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 Führungselementen, die über Kopplungsmittel gegenläufig miteinander verbunden und von den aufwickelbaren oder abwickelbaren Seilsträngen antreibbar sind, wobei die Schiene zumindest zwei sich in Schienenlängsrichtung erstreckende und parallel zueinander in Richtung der Seilstränge gesehen hintereinander angeordnete Spuren aufweist, in denen die Führungselemente jeweils geführt und abgestützt sind.The invention relates to a cable guide for a winch according to the preamble of claim 1, 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 with respect to the guide elements provided for the assigned rope groove, which are connected in opposite directions via coupling means and by the windable or unwindable rope strands can be driven, the rail at least two extending in the longitudinal direction of the rail and parallel to each other in Seen in the direction of the rope strands arranged one behind the other, in which the guide elements are each guided and supported.

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; derartige 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; Such 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 und eine besonders schonende antriebslose Führung der Seilstränge ermöglicht. Die Schiene weist zwei übereinander angeordnete voneinander beabstandete und als seitlich offene Kanäle ausgebildete Spuren zur Führung je eines Führungselementes auf, wobei die Spuren mit in Längsrichtung der Schiene verlaufenden Nuten für darin geführte Gleitleisten versehen sind. Aufgrund der zur stabilen Führung mit entsprechender Stützwirkung erforderlichen relativ großen Länge der Gleitleisten, durch welche die Kräfte über die Führungselemente auf die Schiene übertragen werden, ist eine kompakte Bauweise nur begrenzt möglich; die Führungselemente lassen sich bei dieser Seilführung insbesondere nicht über die gesamte Länge der Schiene bewegen.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 and a particularly gentle one drive-free guidance of the rope strands enabled. The rail has two on top of each other arranged spaced apart and designed as laterally open channels Tracks for guiding one guide element each, the tracks with in Provide grooves running in the longitudinal direction of the rail for slide rails guided therein are. Due to the stable guidance with appropriate support required relatively large length of the slide rails, through which the forces on the Guide elements are transferred to the rail is a compact design only possible to a limited extent; the guide elements can be with this rope guide in particular, do not move the entire length of the rail.

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 aber eine sehr kompakte Bauform aufweist und dabei trotzdem sehr wartungsfrei ist. Insbesondere sollten sich die Führungselemente über die gesamte Länge der Schiene bewegen lassen.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, but at the same time has a very compact design and still very is maintenance free. In particular, the guide elements should cover the entire Let the length of the rail move.

Die Lösung dieser Aufgabe ist erfindungsgemäß gekennzeichnet durch die im Patentanspruch 1 angegebenen Merkmale. Durch die kennzeichnenden Merkmale der Unteransprüche 2 bis 9 ist die Seilführung in vorteilhafter Weise weiter ausgestaltbar.The solution to this problem is characterized by the im Claim 1 specified features. Due to the characteristic features of the Subclaims 2 to 9 can be further configured in an advantageous manner.

Erfindungsgemäß umfassen die Kopplungsmittel in Schienenlängsrichtung gegenläufig zueinander bewegbare Kopplungslängsträger, die jeweils in einer der Spuren geführt und längs der Spur an zumindest zwei beabstandeten Punkten abgestützt sind, wobei jeder Kopplungslängsträger mit einem der Führungselemente starr verbunden ist. Jeweils ein Kopplungslängsträger ist also mit genau einem Führungselement starr verbunden und bildet mit diesem eine in Schienenlängsrichtung bewegbare Einheit, die an zumindest vier Punkten abgestützt ist, wobei die Beabstandung der Stützpunkte relativ groß gewählt werden kann. Die starr verbundene Einheit aus Kopplungslängsträger und Führungselement ist über das Führungselement in verschiedenen Spuren geführt und abgestützt, wobei die Abstützung und Führung der Einheit über den Kopplungslängsträger deutlich verstärkt wird. Die Beabstandung der Abstützpunkte des Kopplungslängsträgers kann dabei relativ groß gewählt werden, so daß insbesondere eine exzellente horizontale Stabilisierung des Führungselements erfolgt, die ein Verklemmen des Führungselements auch bei großen Seilkräften wirkungsvoll verhindert. Dabei ist die erfindungsgemäße Seilführung in sehr kompakter Bauweise ausführbar. Insbesondere ermöglicht es die erfindungsgemäße Bauweise, die Führungselemente über die gesamte Länge der Schiene zu bewegen.According to the invention, the coupling means comprise opposing directions in the longitudinal direction of the rail Coupling longitudinal members movable relative to each other, each guided in one of the tracks and are supported along the track at at least two spaced apart points, wherein each coupling longitudinal member is rigidly connected to one of the guide elements. Each coupling longitudinal member is rigid with exactly one guide element connected and forms a movable unit in the longitudinal direction of the rail is supported at at least four points, the spacing of the support points can be chosen relatively large. The rigidly connected unit Coupling longitudinal member and guide element is in via the guide element led and supported various tracks, the support and guidance of the Unit is significantly strengthened via the coupling side member. The spacing of the Support points of the longitudinal coupling member can be chosen to be relatively large, so that in particular an excellent horizontal stabilization of the guide element takes place, the jamming of the guide element even with large rope forces effectively prevented. The rope guide according to the invention is very compact Construction feasible. In particular, the construction method according to the invention enables to move the guide elements over the entire length of the rail.

Vorteilhafterweise sind die Kopplungslängsträger als Zahnstangen ausgebildet, in die ein in der Schiene frei drehbar gelagertes, die Kopplungslängsträger verbindendes Zahnrad eingreift. Auf diese Weise wird mit sehr einfachen Mitteln die gegenläufige Bewegung der Führungselemente sichergestellt.The coupling longitudinal beams are advantageously designed as toothed racks into which a freely rotatably mounted in the rail, connecting the coupling longitudinal members Gear engages. In this way, the opposite is the case with very simple means Movement of the guide elements ensured.

Dabei sind die Zapfen des Zahnrads mit Spiel in eine in der Schiene vorgesehene Öffnung einsetzbar, was die Fixierung der in den Spuren angeordneten Kopplungslängsträger bei nahezu jeder Lage relativ zueinander ermöglicht, und zwar nahezu ohne Justageaufwand.The pins of the gear are provided with play in one in the rail Opening can be used, which fixes the arranged in the tracks Coupling longitudinal beams made possible in almost any position relative to each other almost without any adjustment effort.

Zweckmäßigerweise ist jeder Kopplungslängsträger jeweils im Bereich der Kopplungslängsträgerenden über horizontal frei drehbar gelagerte Laufräder in der Spur abgestützt. Der hierbei mögliche große Abstand der Laufräder sorgt dabei für eine sehr gute horizontale Stabilisierung des Führungselements; der Einsatz von Laufrollen stellt einen leichtgängigen Lauf des Führungselementes sicher.Each coupling longitudinal beam is expediently in the area of the Coupling longitudinal beam ends via horizontally freely rotatable wheels in the Track supported. The possible large distance between the wheels ensures very good horizontal stabilization of the guide element; the use of Rollers ensure smooth running of the guide element.

Zusätzlich ist jeder Kopplungslängsträger zur Verbesserung der Führung und Abstützung des Führungselements an dem Führungselement abgewandten Kopplungslängsträgerende zumindest über eine vertikal frei drehbar gelagerte Stützrolle in der Spur geführt.In addition, each coupling longitudinal member to improve the leadership and Support of the guide element facing away from the guide element Coupling longitudinal beam end at least via a vertically freely rotatable Support roller guided in the track.

Eine sehr gute Führung und Abstützung ergibt sich, wenn jedes Führungselement jeweils mittels zweier am Führungselement angeordneter Stützrollen in dem in Richtung der Seilstränge gesehen hintereinander angeordneten Spuren abgestützt ist. A very good guidance and support results when each guide element in each case by means of two support rollers arranged on the guide element in the in Direction of the rope strands seen behind one another is supported tracks.

Vorteilhafterweise bilden die Spuren selbst im Querschnittsgrund und/oder an den Seitenflächen Stützflächen.The traces advantageously form themselves in the cross-sectional base and / or on the Side surfaces support surfaces.

Zusätzlich ist es vorteilhaft, die Spuren mit Halteelemten zu versehen, die vertikal angeordnete, in Schienenlängsrichtung verlaufende Stützflächen und/oder Laufflächen und horizontal angeordnete in Schienenlängsrichtung verlaufende Stützflächen und/oder Laufflächen bilden. Diese gewährleisten eine einwandfreie Führung und Abstützung des Führungselements innerhalb der Schiene.In addition, it is advantageous to provide the tracks with holding elements that are vertical arranged support surfaces and / or running surfaces running in the longitudinal direction of the rail and horizontally arranged support surfaces running in the longitudinal direction of the rail and / or form treads. These ensure proper guidance and Support of the guide element within the rail.

Eine besonders schmutzunempfindliche Bauweise der Seilführung wird dadurch gewährleistet, daß die Laufräder und die Stützrollen zumindest teilweise durch Gleitelemente ersetzt sind.This makes the rope guide particularly dirt-resistant ensures that the wheels and support rollers at least partially Sliding elements are replaced.
