Description

Bei einer aus Stahl hergestellten Seillührung nach der CH-A 22 0559 wird das Seil von einer Rolle in die Seilrille gedrückt. Das Seil kann sich aus den Seilrillen herausheben. z. B. wenn der Lasthaken oder die Unterflasche auf einen Gegenstand aufgesetzt wird, der dicht unterhalb der Seiltrommel liegt. Dieses Herausheben des Seils aus den Seilrillen wird bei einer Seilführung nach der DE-C 23 16 930 durch einen Kunststoff-Spannring verhindert. der jedoch zu einer groben Baulänge führt. Die gesamte Seilführung überdeckt 6 Seilwindungen. Die Ringhälften sind aus Stahl hergestellt, die im Bereich des Seilschlitzes durch eine Verbindungslasche miteinander verbunden sind. Die aus Stahl hergestellten Ringhälften sind schwer und teuer; das grobe Gewicht ist bei der Montage und vor allem bei Reparaturen von Nachteil. Der Rand der Verbindungsiasche hat auf der Seite des Schlitzes scharfe Kanten, die einen Schrägzug des Seils begrenzen oder beim Überschreiten des möglichen Schrägzuges das Seil beschädigen können bzw, von diesem beschädigt werden. Ein weiterer Nachteil ist, daß die aus Stahl hergestellten Ringhälften zum Gleiten in den Seilrillen mit Schmierfett versehen werden müssen.In the case of a rope guide made of steel according to CH-A 22 0559, the rope is pressed into the groove by a roller. The rope can lift out of the rope grooves. e.g. B. when the load hook or the bottom block is placed on an object that lies just below the rope drum. This lifting of the rope out of the rope grooves is prevented in a rope guide according to DE-C 23 16 930 by a plastic tension ring. which, however, leads to a rough overall length. The entire rope guide covers 6 turns of rope. The ring halves are made of steel, which are connected to each other in the area of the cable slot by a connecting strap. The ring halves made of steel are heavy and expensive; the coarse weight is disadvantageous during assembly and especially when carrying out repairs. The edge of the connecting liner has sharp edges on the side of the slot, which limit an inclined pull of the rope or, if the possible inclined pull is exceeded, can damage or be damaged by the rope. Another disadvantage is that the ring halves made of steel must be provided with lubricating grease for sliding in the cable grooves.

Aufgabe der Erfindung ist es daher, eine kostengünstige, leichte und damit montagefreundliche Seilführung zu schaffen, die wartungsarm und schmiermittelfrei ist und auch außergewöhnlich große Seilablenkungen ohne Beschädigung von Teilen zuläßt, wobei die Baulänge trotz sicheren Haltens des Seiles auf der Trommel kurz ist. Diese Aufgabe wird ausgehend von der Seilführung nach der DE-C 23 16 930 dadurch gelöst, daß die Seilführung einen Aufbau entsprechend den Merkmalen im Anspruch 1 aufweist.The object of the invention is therefore to provide an inexpensive, light and therefore easy-to-assemble cable guide, which is low-maintenance and lubricant-free and also allows extraordinarily large cable deflections without damage to parts, the overall length being short despite the safe holding of the cable on the drum. This object is achieved on the basis of the cable guide according to DE-C 23 16 930 in that the cable guide has a structure corresponding to the features in claim 1.

Die Länge der Seillührung erstreckt sich nur über ca. 5 Seilwindungen, so daß die Länge der Seiltrommel bei vorgegebenem Hakenweg gegenüber der Seillührung nach der DE-C 23 16 930 um eine Seilwindung kürzer sein kann. Die federnd gelagerte Rolle drückt das Seil in die Seilrille. Selbst beim Einschieben des Seiles in den Seileinlauf gleitet es unter normalen Betriebsbedingungen nicht unter der Rolle an der Seilrille entlang, da der Reibwiderstand zwischen Seil und Seilrille sehr groß ist gegenüber dem Widerstand zwischen dem Seil und der Rolle. Sollte es dennoch hochgeschoben werden so verhindern der Seilniederhalter und der Führungsbügel ein weiteres Aufschieben bzw. Herausspringen des Seiles aus den Seilrillen. Die Rolle umfaßt zusammen mit dem Seilniederhalter und dem Führungsbügel annähernd den gesamten Seiltrommelumfang.The length of the rope guide extends only over about 5 turns of rope, so that the length of the rope drum can be shorter by one rope turn for a given hook path than the rope guide according to DE-C 23 16 930. The spring-loaded roller presses the rope into the rope groove. Even when the rope is inserted into the rope inlet, it does not slide under the roller along the rope groove under normal operating conditions, since the frictional resistance between the rope and the rope groove is very large compared to the resistance between the rope and the roller. Should it nevertheless be pushed up, the cable hold-down device and the guide bracket prevent the cable from being pushed further or jumping out of the cable grooves. Together with the cable hold-down device and the guide bracket, the roller covers almost the entire circumference of the cable drum.

Der Kunststolf ist vorzugsweise Polyamid mit einem gefüllten Zusatz von MoS2. Polyamid 6.6 mit dem Zusatz Molybdändisulfid hat bei ausreichender Festigkeit eine Elastizität, die auch größere Verformungen schadlos ermöglicht und wegen des MoS2-Zusatzes keine Schmierung erfordert. so daß auch keine Schmiermittelreste vom Kran herunterfallen und Schäden anrichten können, z. B. bei Lebensmitteln, Kleidung usw. Das Gewicht der Kunststolf-Seilführung beträgt nur etwa 10 bis 15 % der bisher üblichen. aus Stahl hergestellten Seillührung und ist daher wesentlich leichter zu montieren. Dies ist bei nachträglichen Änderungen und Reparaturen auf einer Kranbrücke von besonderer Bedeutung. Der Kunststoff ist in einem Temperaturbereich von -40 bis + 100 °C einsetzbar. Durch die lösbare Befestigung des Führungsbügels am Führungssegment und durch dessen Trennung vom Haltesegment kann die Seilführung in einfacher Weise gelöst werden, so daß das Seil leicht gewechselt werden kann.The plastic is preferably polyamide with a filled addition of MoS2. With sufficient strength, polyamide 6.6 with the addition of molybdenum disulphide has an elasticity that also allows larger deformations without damage and requires no lubrication due to the MoS2 addition. so that no lubricant residues can fall off the crane and cause damage, e.g. B. for food, clothing, etc. The weight of the Kunststolf rope guide is only about 10 to 15% of the usual. rope guide made of steel and is therefore much easier to assemble. This is particularly important for subsequent changes and repairs on a crane bridge. The plastic can be used in a temperature range from -40 to + 100 ° C. By releasably attaching the guide bracket to the guide segment and separating it from the holding segment, the cable guide can be released in a simple manner, so that the cable can be changed easily.

In weiterer Ausgestaltung der Erfindung haben das Führungssegment und das Haltesegment sich überlappende Enden mit Bohrungen für Verbindungsbolzen. Die den Seileinlauf bildenden Flächen des Führungsbügels und des Führungssegmentes haben Einlaufschrägen, die einen Schrägzugwinkel des Seiis von ± 4° ohne Berührung zulassen. Falls die Gefahr eines gröberen Schrägzugwinkels besteht, kann an dem Führungsbügel auf der dem Schlitz gegenüberliegenden Seite ein aus Stahl hergestellter Verstärkungswinkel befestigt sein, der ein übermäßiges Verbiegen des Kunststoff-Führungsbügels verhindert. Bei Varwendung des Verstärkungswinkels kann die Seilablenkung biszu± 100 betragen. Es liegt dann an den Einlaufschrägen an und gleitet, ohne daß Teile beschädigt werden. Das Führungssegmentwird bei dieser starken Ablenkung in die Seilrillen gedrückt. Beim starken Ablenken des Seils über den Führungsbügel verformt dieser sich bis zum Aufliegen auf der Sellwindung. Das Führungssegment und der Führungsbügel können an den einander abgekehrten Flächen von Stegen begrenzte Ausnehmungskammern haben, die außer dem Vorteil einer Material- und Gewichtseinsparung zur Steigerung der Elastizität dieser Teile beitragen.In a further embodiment of the invention, the guide segment and the holding segment have overlapping ends with bores for connecting bolts. The surfaces of the guide bracket and the guide segment that form the cable entry have run-in bevels that allow a bevel pull angle of the screen of ± 4 ° without contact. If there is a risk of a coarse oblique pull angle, a reinforcement angle made of steel can be fastened to the guide bracket on the side opposite the slot, which prevents the plastic guide bracket from bending excessively. If the reinforcement angle is used, the cable deflection can be up to ± 100. It then lies against the run-in slope and slides without damaging parts. The guide segment is pressed into the cable grooves during this strong deflection. When the rope is strongly deflected via the guide bracket, it deforms until it rests on the sell turn. The guide segment and the guide bracket can have recessed chambers delimited on the surfaces facing away from one another, which, in addition to the advantage of saving material and weight, contribute to increasing the elasticity of these parts.

In weiterer Ausgestaltung der Erfindung sind die Rollen auf Achsen in U-förmigen Rollen böcken unter Belassung eines Zwischenraumes gelagert sind. Dieser Zwischenraum ermöglicht das Verschieben der Rollen in den Rollenböcken und die Rollen passen sich selbsttätig etwaigen Toleranzen in der Rillensteigung und Seillage an und wirken auch ausgleichend bei einem übermäßigen Seilschrägzug.In a further embodiment of the invention, the rollers are supported on axles in U-shaped rollers and are left with an intermediate space. This space allows the rollers to be moved in the roller stands and the rollers automatically adapt to any tolerances in the groove pitch and rope position and also have a compensating effect in the event of excessive cable pull.

Die Rollen der Lagerbolzen. die Rollenböcke. die Achsen und die Feder sind aus Stahl hergestellt. Die Rollen sind gehärtet und mit Wälzlagern auf den Achsen gelagert, damit sie beim Aufwickeln und Abwickeln des Seils einen geringen Drehwiderstand haben.The roles of the bearing bolts. the roller blocks. the axles and the spring are made of steel. The rollers are hardened and have roller bearings on the axles so that they have little resistance to rotation when winding and unwinding the rope.

Der Kunststolf-Federbügel ist mit einer Kunststoff-Führungsklaue an einer Schiene der Seilwinde axial verschiebbar geführt und am Mitdrehen beim Drehen der Seiltrommel gehindert. Die Führungsklaue geht in einen unteren Einlaufbegrenzer über. der zusammen mit einem oberen Einlaufbegrenzer die Verbindung vom Führungsbügel zum Führungssegment bildet. Durch die Verbindung führt eine Schraube. Der gewählte Werkstoff - Kunststoff mit MoS2 gefüllt - gestattet den Einsatz der Seilführung im extremen Temperaturbereich. Die Form, insbesondere die Gestaltung des Seilschlitzes sowie die axiale Verschiebbarkeit der das Seil in die Seilrillen drückenden Rollen sowie die Anordnung des Seilniederhalters am Gegensegment sind so gestaltet, daß auch bei außergewöhnlichem Schrägzug keine übermäßige Beanspruchung und Verschleiß der Bauteile eintritt, so daß keine Störungen im Betriebsablauf an einer mit dieser kurzen Kunststoff-Seilführung ausgerüstete Seilwinde auftritt.The plastic spring clip is axially displaceably guided on a rail of the cable winch with a plastic guide claw and is prevented from rotating when the cable drum rotates. The guide claw passes into a lower inlet limiter. which, together with an upper inlet limiter, forms the connection from the guide bracket to the guide segment. A screw runs through the connection. The selected material - plastic filled with MoS2 - allows the cable guide to be used in the extreme temperature range. The shape, in particular the design of the cable slot as well as the axial displaceability of the rollers pressing the cable into the cable grooves and the arrangement of the cable hold-down device on the counter-segment are designed in such a way that excessive stress and wear on the components does not occur, even with an unusual inclined pull, so that no faults occur in the Operating sequence occurs on a cable winch equipped with this short plastic cable guide.

Ein durch eine strichpunktierte Linie angedeutetes Seil 1 wird beim Aufwickeln auf eine Seiltrommel 2 durch einen Schlitz 3 eines Führungsbügels 4 geführt, der mit einem Verstärkungswinkel 5 versehen und mit einem Führungssegment 6 verbunden ist. Dieses ist mittels zweier durch sich überlappende Enden 11 geführter Bolzen 10 mit einem Haltesegment 7 verbunden und ebenso wie das Führungssegment 6 mit Gewindeprofil 8 an den Seilrillen der Seiltrommel 2 geführt. Das Haltesegment 7 hat neben dem Gewindeprofil 8 einen Seilniederhalter 9, der auf der dem Schlitz 3 gegenüberliegenden Seite der Seiltrommel 2 zwei Windungen des Seils 1 abdeckt, wie in Fig. 4 zu erkennen ist. Diese Fig. zeigt auch. daß der Verstärkungswinkel 5 in der Endlage der Seilführung über eine gestrichelt gezeichnete Seilklammer 26 der Seiltrommel 2 mit seinem Schenkel 5a ragt und damit die wirksame Breite reduziert, womit ein besonders kleines Anfahrmaß zur Seilbefestigung erreicht wird.A rope 1 indicated by a dash-dotted line is passed through a slot 3 of a guide bracket 4 when wound onto a rope drum 2, which is provided with a reinforcement angle 5 and is connected to a guide segment 6. This is connected to a holding segment 7 by means of two bolts 10 guided through overlapping ends 11 and, like the guide segment 6 with a thread profile 8, is guided on the cable grooves of the cable drum 2. In addition to the threaded profile 8, the holding segment 7 has a cable hold-down device 9, which on the side of the cable drum 2 opposite the slot 3 covers two turns of the cable 1, as can be seen in FIG. 4. This figure also shows. that the reinforcement angle 5 in the end position of the rope guide protrudes with a dashed rope clip 26 of the rope drum 2 with its leg 5a and thus reduces the effective width, thus achieving a particularly small approach dimension for rope attachment.

Das Seil 1 wird oberhalb des mit Einlaufschrägen 22 versehenen Schlitzes 3 mit am Führungssegment 6 angeordneten Rollen 12 in die Seilrillen geleitet. Hierzu trägt ein im Führungssegment 6 befestigter Lagerbolzen 13 zwei Rollenböcke 14 mit Achsen 16 für die Rollen 12. Diese werden von einer Feder 17 auf das einlaufende Seil 1 gedrückt, wobei sich die Feder 17 an sich gegenüberliegenden Stützkanten 15 der Rollenböcke 14 abstützt. Aus den Stützkanten 15 vorstehende Zapfen bilden Führungen für die schraubenförmige Feder 17. Damit das Andrücken des Seils 1 auch bei schrägem Seileinlauf gewährleistet ist, sind, wie Fig. 5 zeigt, zwischen den Rollen 12 und den Wänden der U-förmigen Rollenböcke 14 Zwischenräume 18 vorhanden, die ein Verschieben der Rollen 12 auf ihren Achsen 16 ermöglichen. Das Führungssegment 6 ist für links- und rechtgängige Seiltrommeln verwendbar; die Rollenböcke 14 für die Rollen 12 müssen dann lediglich umgesetzt werden.The rope 1 is guided above the slot 3 provided with run-in slopes 22 with rollers 12 arranged on the guide segment 6 into the rope grooves. For this purpose, a bearing pin 13 fastened in the guide segment 6 carries two roller blocks 14 with axes 16 for the rollers 12. These are pressed by a spring 17 onto the incoming rope 1, the spring 17 being supported on opposite supporting edges 15 of the roller blocks 14. Pins protruding from the supporting edges 15 form guides for the helical spring 17. In order to ensure that the cable 1 is pressed on even when the cable entry is at an angle, 14 spaces 18 are provided between the rollers 12 and the walls of the U-shaped roller blocks, as shown in FIG. 5 available, which allow the rollers 12 to be moved on their axes 16. The guide segment 6 can be used for left-handed and right-handed rope drums; the roller blocks 14 for the rollers 12 then only have to be implemented.

Beim Drehen der Seiltrommel 2 bewegt sich die gesamte Seilführung entsprechend der Drehrichtung und der Steigung der Seilrillen wegen der dahineinragenden Gewindeprofils 8 nach links oder rechts. Ein Mitdrehen der Seilführung wird durch eine mit dem Führungsbügel verbundene Führungsklaue 19 verhindert, die eine nicht gezeichnete Schiene der Winde umfaßt und daran entlanggleitet. Die Führungsklaue 19 geht in eine untere Einlaufschräge 23 über, die zusammen mit einer oberen Einlaufschräge 24 die mittels Schrauben 25 herstellbare Verbindung zum Führungssegment bildet.When the cable drum 2 is rotated, the entire cable guide moves to the left or right in accordance with the direction of rotation and the gradient of the cable grooves because of the thread profile 8 protruding there. A co-rotation of the cable guide is prevented by a guide claw 19 connected to the guide bracket, which includes a not shown rail of the winch and slides along it. The guide claw 19 merges into a lower run-in slope 23 which, together with an upper run-in slope 24, forms the connection to the guide segment which can be produced by means of screws 25.

Der Führungsbügel 4 und das Führungssegment 6 haben zur Materialeinsparung und, zum Erhöhen der Elastizität auf der dem Schlitz 3 gegenüberliegenden Seite Ausnehmungskammern 20, die durch Stege 21 voneinander getrennt sind.The guide bracket 4 and the guide segment 6 have, in order to save material and to increase the elasticity on the side opposite the slot 3, recess chambers 20 which are separated from one another by webs 21.
