Description

Die Erfindung betrifft eine Seilflasche gemäß dem Oberbegriff von Anspruch 1. Auch betrifft die Erfindung ein Verfahren zur Montage eines Abdeckelements an einer entsprechenden Seilflasche.The invention relates to a cable bottle according to the preamble of claim 1. The invention also relates to a method for mounting a cover to a corresponding cable bottle.

Aus dem europäischen Patent EP 1 457 455 B1 ist eine derartige Seilflasche in Form einer Unterflasche für Seilzüge bekannt. Die Unterflasche besteht im Wesentlichen aus einem zentralen Verbindungselement, das sowohl die Funktion einer Achse für hieran an beiden Enden drehbar gelagerte Seilrollen als auch die Funktion eines Aufnahmeelementes für einen Lasthaken in sich vereint. Der Lasthaken ist um eine vertikale Achse drehbar von unten in dem Verbindungselement gelagert. An gegenüberliegenden Seiten des Verbindungselements sind die beiden Seilrollen koaxial zueinander sowie drehbar gelagert. Über die Seilrollen sind eingescherte Lastseile geführt, die zu dem Seilzug laufen. Die Seilrollen sind mit Abdeckhauben als Unfallschutz versehen. Die Abdeckhauben sollen verhindern, dass die Finger beziehungsweise Hände eines Bedieners zwischen Seil und Seilrolle eingezogen und eingeklemmt werden. Entsprechend der Außenkontur der Seilrollen haben die Abdeckhauben annähernd eine kreisscheibenförmige Außenform und sind für die Montage in Axialrichtung der Seilrollen geteilt. Die Längsteilung verläuft so, dass ein deckelförmiges äußeres Haubenteil entsteht, dass seitlich von außen über die Seilrolle aufgesetzt wird, bis es an einem inneren Haubenteil zur Anlage kommt und dort befestigt wird. Die umlaufende Trennlinie der beiden Haubenteile verläuft in Radialrichtung der Seilrollen gesehen etwa in Bereich der Mitte einer Seilrille der Seilrolle. Das innere Haubenteil ist ringförmig und mit einem äußeren umlaufenden Rand ausgebildet, an dem das äußere Haubenteil zur Anlage kommt, und ist integraler Bestandteil des Verbindungselements. Jede der Abdeckhauben ist mit zwei Ein- und Austrittsöffnungen versehen, damit das um die Seilrolle geführte Lastseil in die Abdeckhaube eintreten sowie wieder aus dieser austreten kann.From the European patent EP 1 457 455 B1 Such a rope bottle in the form of a lower block for cables is known.

On opposite sides of the connecting element, the two pulleys are coaxial with each other and rotatably mounted. About the pulleys sheared load cables are guided, which run to the cable. The pulleys are provided with covers as accident protection. The covers are to prevent the fingers or hands of an operator between rope and pulley are fed and clamped. According to the outer contour of the pulleys, the covers have approximately a circular disk-shaped outer shape and are divided for mounting in the axial direction of the pulleys. The longitudinal pitch is such that a lid-shaped outer hood part is formed that is placed laterally from the outside on the pulley until it comes to an inner hood part to the plant and is fixed there. The circumferential parting line of the two hood parts extends in the radial direction of the pulleys seen approximately in the region of the center of a rope groove of the pulley. The inner hood part is annular and formed with an outer circumferential edge on which the outer hood part comes to rest, and is an integral part of the connecting element. Each of the cover hoods is provided with two inlet and outlet openings so that the load rope guided around the cable pulley can enter the cover hood and exit from it again.

Die Seilöffnungen weisen eine Breite auf, die etwa der Breite der Seilrille der Seilrolle und somit etwa dem 3-fachen des Lastseildurchmessers entsprechen. Die Länge der Seilöffnung beträgt bezogen auf den Umfang der Seilrolle beziehungsweise der Abdeckhaube etwa 90°, wobei im oberen Bereich der Abdeckhaube zwischen den beiden Ein- und Austrittsöffnungen ein Trennsteg verbleibt. Unter der Annahme, dass der Nullpunkt der Winkelangaben oben in die Mitte der Abdeckhaube gelegt wird, beginnt die erste Ein- und Austrittsöffnung etwa bei 15° und läuft bis 105° und die zweite Ein- und Austrittsöffnung erstreckt sich von 255° bis 345°. Die Ein- und Austrittsöffnungen weisen eine derartig große Längserstreckung in Umfangsrichtung der Seilrolle auf, da der Öffnungswinkel zwischen den beiden Trumen der Lastseilen in Abhängigkeit von der Ausgestaltung des Seilzugs und des Abstandes zwischen dem Seilzug und der Unterflasche etwa zwischen 0° und 30° variieren kann. Entsprechender Weise wandert der Ablaufpunkt des Lastseiles von der Seilrolle im Bereich der Ein- und Austrittsöffnungen und in Umfangsrichtung der Seilrolle. Da der Durchmesser des Seils nur einen Bruchteil der Länge der Ein- und Austrittsöffnung beträgt, ist in jede der Ein- und Austrittsöffnungen ein Abdeckelement eingesetzt, das die Ein- und Austrittsöffnung mit Ausnahme einer Öffnung für das Seil verschließt. Diese Öffnung ist nur geringfügig größer als der Durchmesser des Seils. Hierdurch wird verhindert, dass die Hand oder die Finger eines Bedieners der Unterflasche von dem Lastseil in den verbleibenden Freiraum der Ein- und Austrittsöffnung eingezogen werden kann. Dieses Abdeckelement ist in der schlitzförmigen Ein- und Austrittsöffnung in Umfangsrichtung der Seilrolle verschiebbar gehalten, um sich parallel mit der Wanderung der Seilablaufpunkte in der Ein- und Austrittsöffnung mitzubewegen. Hierbei überdeckt das Abdeckelement einerseits die Ein- und Austrittsöffnung von außen und umgreift andererseits in einem mittleren Bereich der der Ein- und Austrittsöffnung - in Umfangsrichtung der Seiltrolle und in einer Mittenstellung des Abdeckelements bezogen auf die Ein- und Austrittsöffnung gesehen - die Ränder der Seilöffnung u-förmig nach innen. Das Abdeckelement besteht im Wesentlichen aus einer oberen Grundleiste, einer schmalen Stegleiste und einer unteren Halteleiste, die zueinander einen H-förmigen Querschnitt aufweisen. Außerdem ist das Abdeckelement als Kunststoffspritzgusssteil einteilig ausgebildet. Für eine Montage des Abdeckelements ist dieses an einem Ende des Seils aufzuschieben und das äußere Haubenteil ist zumindest zu lockern, um die schlitzförmige Ein- und Austrittsöffnung für ein Einführen der unteren Halteleiste zu erweitern.The rope openings have a width which corresponds approximately to the width of the rope groove of the rope pulley and thus about 3 times the load rope diameter. The length of the Cable opening is based on the circumference of the pulley or the cover about 90 °, wherein in the upper part of the cover between the two inlet and outlet openings a divider remains. Assuming that the zero point of the angle data is placed at the top in the center of the cover, the first inlet and outlet opening starts at about 15 ° and runs to 105 ° and the second inlet and outlet opening extends from 255 ° to 345 °. The inlet and outlet openings have such a large longitudinal extent in the circumferential direction of the pulley, since the opening angle between the two strands of the load cables depending on the configuration of the cable and the distance between the cable and the bottom block can vary between about 0 ° and 30 ° , Correspondingly, the flow point of the load rope moves from the pulley in the region of the inlet and outlet openings and in the circumferential direction of the pulley. Since the diameter of the rope is only a fraction of the length of the inlet and outlet openings, a cover element is used in each of the inlet and outlet openings, which closes the inlet and outlet openings except for an opening for the rope. This opening is only slightly larger than the diameter of the rope. This prevents that the hand or the fingers of an operator of the bottom block of the load rope can be pulled into the remaining space of the inlet and outlet opening. This cover is slidably held in the slot-shaped inlet and outlet opening in the circumferential direction of the pulley in order to move in parallel with the migration of the cable drain points in the inlet and outlet opening. On the one hand, the cover element covers the inlet and outlet openings from the outside and, on the other hand, surrounds the edges of the rope opening u in a central area of the inlet and outlet opening, viewed in the circumferential direction of the cable pulley and in a central position of the cover element relative to the inlet and outlet openings -shaped inside. The cover consists essentially of an upper base strip, a narrow web bar and a lower retaining strip, which have an H-shaped cross section to each other. In addition, the cover is integrally formed as a plastic injection molded part. For an assembly of the cover this is postponed at one end of the rope and the outer hood part is at least loosen to expand the slot-shaped inlet and outlet opening for insertion of the lower retaining strip.

Aus der DE 10 2008 059 071 B3 ist eine Seilflasche mit einem teilbaren Abdeckelement bekannt. Das Abdeckelement ist in eine Ein- und Austrittsöffnung einer Abdeckhaube der Seilflasche unterhalb der Ein- und Austrittsöffnung so eingesetzt, dass das eingesetzte Abdeckelement die Abdeckhaube hierbei nicht von oben durch- oder hintergreift.From the DE 10 2008 059 071 B3 is a rope bottle with a divisible Cover known. The cover is inserted into an inlet and outlet opening of a cover of the cable bottle below the inlet and outlet openings so that the cover used here, the cover here not durchgreift from above or behind.

Der vorliegenden Erfindung liegt die Aufgabe zu Grunde, eine verbesserte und wartungsfreundliche Seilflasche, insbesondere Unterflasche, für Seilzüge, zu schaffen.The object of the present invention is to provide an improved and maintenance-friendly cable bottle, in particular a lower bottle, for cables.

Diese Aufgabe wird erfindungsgemäß durch eine Seilflasche mit den Merkmalen des Anspruchs 1 gelöst. In den abhängigen Ansprüchen sind vorteilhafte Ausgestaltungen der Seilflasche angegeben. Auch wird die Aufgabe durch ein Verfahren zur Montage eines Abdeckelements an einer Seilflasche nach Anspruch 10 gelöst.This object is achieved by a cable bottle with the features of claim 1. In the dependent claims advantageous embodiments of the rope bottle are given. The object is also achieved by a method for mounting a cover element on a cable bottle according to claim 10.

Erfindungsgemäß wird bei einer Seilflasche, insbesondere Unterflasche für Seilzüge, mit mindestens einer von einer Abdeckhaube mit Ein- und Austrittsöffnungen für ein Lastseil umgebenen Seilrolle, wobei in mindestens eine der Ein- und Austrittsöffnungen ein Abdeckelement eingesetzt und über eine einen Rand der Ein-und Austrittsöffnung hintergreifende Halteleiste in der Ein- und Austrittsöffnung gehalten ist, das Abdeckelement eine Öffnung für das Lastseil aufweist und die Öffnung in dem Abdeckelement kleiner als die Ein- und Austrittsöffnung in der Abdeckhaube ist, eine Wartungsfreundlichkeit dadurch erreicht, dass das Abdeckelement derart mindestens in ein erstes Abdeckteil und ein zweites Abdeckteil geteilt ist, dass für eine Montage des Abdeckelements an der Abdeckhaube das erste Abdeckteil und das zweite Abdeckteil bei eingeschertem Lastseil mit ihren Halteleisten in die Ein- und Austrittsöffnung einfügbar sind, dann den Rand der Ein-und Austrittsöffnung hintergreifen und abschließend zu dem Abdeckelement in einen montierten Einbauzustand zusammenfügbar sind. Somit kann vermieden werden, für die Montage das Lastseil neu einscheren zu müssen und Haubenteile der Abdeckhaube für eine Verbreiterung der Ein- und Austrittsöffnung öffnen zu müssen.According to the invention, in a cable bottle, in particular lower case for cables, with at least one pulley surrounded by a cover with inlet and outlet openings for a load rope, wherein inserted into at least one of the inlet and outlet openings a cover and an edge of the inlet and outlet opening engaging behind retaining strip is held in the inlet and outlet opening, the cover has an opening for the load rope and the opening in the cover is smaller than the inlet and outlet opening in the cover, a maintenance friendliness achieved in that the cover so at least in a first Cover part and a second cover is divided, that for mounting the cover to the cover, the first cover and the second cover are inserted with sheared load rope with their retaining strips in the inlet and outlet opening, then hintergre the edge of the inlet and outlet openings ifen and finally be joined to the cover in an assembled state installation. Thus, it can be avoided to recut the load rope for assembly and to have to open hood parts of the cover for broadening the inlet and outlet openings.

Das Abdeckelement mit seiner relativ kleinen Öffnung verhindert erfolgreich, dass eine Hand oder die Finger des Bedieners von dem Lastseil in die Seilöffnung der Abdeckhaube gezogen werden können. Außerdem wird in vorteilhafter Weise von dem Abdeckelement verhindert, dass das in die Abdeckhaube einlaufende und hieraus auslaufende Lastseil an dem Rand der Ein- und Austrittsöffnungen der Abdeckhaube schleift und somit verschleißt. Auch ist die Seilrolle besser gegen das Eindringen von Staub, Schmutz und Feuchtigkeit geschützt.The cover with its relatively small opening successfully prevents a hand or the operator's fingers can be pulled by the load rope in the cable opening of the cover. In addition, it is advantageously prevented by the cover, that the incoming and outgoing in the cover load rope grinds at the edge of the inlet and outlet openings of the cover and thus wears. Also, the pulley is better protected against the ingress of dust, dirt and moisture.

Vorteilhafter Weise ist vorgesehen, dass in Umfangsrichtung der Seilrolle gesehen an dem ersten Abdeckteil ein Teil der Halteleiste für den zugeordneten seitlichen Rand der Ein- und Austrittsöffnung und an dem zweiten Abdeckteil ein weiterer Teil der Halteleiste für den zugeordneten anderen seitlichen Rand der Ein- und Austrittsöffnung angeordnet ist. Hierdurch kann das Abdeckelement einfach an der Abdeckhaube im Bereich der Ein- und Austrittsöffnung befestigt werden.Advantageously, it is provided that seen in the circumferential direction of the pulley on the first cover part of the retaining strip for the associated lateral edge of the inlet and outlet and on the second cover another part of the retaining strip for the associated other lateral edge of the inlet and outlet opening is arranged. As a result, the cover can be easily attached to the cover in the region of the inlet and outlet opening.

Eine Austauschbarkeit der Abdeckelemente bei Verschleiß kann dadurch vereinfacht werden, dass das erste Abdeckteil und das zweite Abdeckteil lösbar im montierten Einbauzustand miteinander verbunden sind. Diese lösbare Verbindung kann insbesondere über eine Schraubverbindung erfolgen.Exchangeability of the cover when worn can be simplified, that the first cover and the second cover are detachably connected together in the assembled state. This releasable connection can be made in particular via a screw connection.

Eine besonders einfache Montage wird dadurch erreicht, dass das Abdeckelement in das erste Abdeckteil und das zweite Abdeckteil in einer Ebene geteilt ist, die in Radialrichtung der Seilrolle ausgerichtet ist und im Bereich der Öffnung des Abdeckelements verläuft.A particularly simple assembly is achieved in that the cover member is divided into the first cover member and the second cover member in a plane which is aligned in the radial direction of the pulley and extends in the region of the opening of the cover.

Eine besonders lange Haltbarkeit des Abdeckelements wird dadurch erreicht, dass die Ein- und Austrittsöffnung schlitzförmig ist und das Abdeckelement in der Ein- und Austrittsöffnung in Umfangsrichtung der Seilrolle verschiebbar ist.A particularly long durability of the cover is achieved in that the inlet and outlet openings are slot-shaped and the cover is displaceable in the inlet and outlet opening in the circumferential direction of the pulley.

Eine einfache Befestigung des Abdeckelements an der Abdeckhaube wird dadurch erreicht, dass das Abdeckelement die Ein- und Austrittsöffnung von außen überdeckt und nach innen die Ränder der Ein- und Austrittsöffnung mit der Halteleiste umgreift.A simple attachment of the cover to the cover is achieved in that the cover covering the inlet and outlet openings from the outside and surrounds the edges of the inlet and outlet openings with the retaining strip inwards.

In konstruktiver Hinsicht besonders einfach umfasst das Abdeckelement eine Grundleiste, eine Stegleiste und eine Halteleiste, die zusammen einen H-förmigen Querschnitt aufweisen, und die Halteleiste liegt mit ihrer Führungsfläche an der Innenfläche der Abdeckhaube im Bereich der Ein- und Austrittsöffnung an.In constructive terms, the cover element comprises a base strip, a web strip and a retaining strip, which together have an H-shaped cross-section, and the retaining strip lies with its guide surface on the Inner surface of the cover in the region of the inlet and outlet opening.

Um eine gute Führung über das Lastseil zu erreichen, ist vorgesehen, dass das Abdeckelement an einem Ende dreieckförmig zu einem Führungsbereich erweitert ist, der die als Kanal ausgebildete Öffnung für das Lastseil aufnimmt.In order to achieve a good guidance on the load rope, it is provided that the cover is widened at one end triangular to a guide portion which receives the opening formed as a channel for the load rope.

Es ist zum Erreichen der Montagefreundlichkeit ausreichend, wenn das Abdeckelement im Führungsbereich in das erste Abdeckteil und das zweite Abdeckteil geteilt ist und die Halteleiste im Führungsbereich an dem Abdeckelement angeordnet ist.It is sufficient to achieve ease of assembly when the cover is divided in the guide area in the first cover and the second cover and the retaining strip is arranged in the guide area on the cover.

Erfindungsgemäß wird eine einfache Montage des Abdeckelements an der Abdeckhaube dadurch erreicht, dass bei einem Verfahren zur Montage des Abdeckelements an der Seilflasche das erste Abdeckteil mit seinem Teil der Halteleiste in die Ein- und Austrittsöffnung entlang des Lastseils eingeführt wird, dann das erste Abdeckteil in Axialrichtung der Seilrolle verschoben wird, so dass der Teil der Halteleiste den zugeordneten Rand der Ein- und Austrittsöffnung hintergreift, dann das zweite Abdeckteil in einen nicht von dem ersten Abdeckteil belegten Teil der Ein-und Austrittsöffnung mit seinem Teil der Halteleiste eingeführt wird, dann das zweite Abdeckteil in Axialrichtung der Seilrolle verschoben wird, so dass der Teil der Halteleiste den anderen gegenüberliegenden und zugeordneten Rand der Ein- und Austrittsöffnung hintergreift, das zweite Abdeckteil in der Ein- und Austrittsöffnung in Umfangsrichtung der Seilrolle in Richtung des ersten Abdeckteils verschoben wird, so dass sich die Teile der Öffnung für das Lastseil zu einer gemeinsamen Öffnung ergänzen, dann das erste Abdeckteil und das zweite Abdeckteil in Axialrichtung der Seilrolle aufeinander zu geschoben werden und lösbar miteinander verbunden werden. Somit kann vermieden werden, für die Montage das Lastseil neu einscheren zu müssen und Haubenteile für eine Verbreiterung der Ein- und Austrittsöffnung öffnen zu müssen.According to the invention, a simple mounting of the cover to the cover is achieved in that in a method for mounting the cover on the cable bottle, the first cover is inserted with its part of the retaining strip in the inlet and outlet opening along the load rope, then the first cover in the axial direction the pulley is moved so that the part of the retaining strip engages behind the associated edge of the inlet and outlet openings, then the second cover is inserted into a not occupied by the first cover part of the inlet and outlet opening with its part of the retaining strip, then the second Cover member is displaced in the axial direction of the pulley, so that the part of the retaining strip engages behind the other opposite and associated edge of the inlet and outlet, the second cover is moved in the inlet and outlet opening in the circumferential direction of the pulley in the direction of the first cover, so that yourself complement the parts of the opening for the load cable to a common opening, then the first cover and the second cover are pushed toward each other in the axial direction of the pulley and are releasably connected together. Thus, it can be avoided to recut the load rope for assembly and to have to open hood parts for a broadening of the inlet and outlet opening.

Die Figur 1 zeigt eine perspektivische Ansicht einer erfindungsgemäßen als Unterflasche 1 ausgebildeten Seilflasche, die über zwei um Seilrollen 2 (siehe auch Figur 2) geführte Paare von Lastseilen 3 an einem nicht dargestellten Seilzug aufgehängt ist. In der Figur 1 sind nur drei der jeweils aus der Unterflasche 1 ausbeziehungsweise eintretenden Trume der beiden Paare von Lastseilen 3 dargestellt, da ein viertes von der Unterflasche 1 verdeckt ist. Die Unterflasche 1 besteht im Wesentlichen aus einem zentralen Verbindungselement 4 mit zwei seitlich hieran gelagerten Seilrollen 2 und einem von unten hieran aufgehängtem Lasthaken 5. Der Lasthaken 5 ist um eine vertikale Achse drehbar in einer Ausnehmung des Verbindungselements 4 über ein nicht dargestelltes Axiallager gelagert. Die koaxial zueinander angeordneten und über das Verbindungselement 4 voneinander beabstandeten Seilrollen 2 sind jeweils von Abdeckhauben 6 umgeben, die in Axialrichtung der Seilrolle 2 gesehen in ein äußeres Haubenteil 6a und ein inneres Haubenteil 6b in der Ebene der Seilrolle 2 geteilt sind. Die beiden Haubenteile 6a, 6b sind identisch ausgebildet. Das äußere Haubenteil 6a und das innere Haubenteil 6b sind jeweils als flache Ringscheiben mit einem außen umlaufenden und kreisbogenförmigen Rand 6c ausgebildet. Das äußere Haubenteil 6a und das innere Haubenteil 6b sind somit schalen- oder tellerförmig ausgebildet. Im montierten Zustand liegt das äußere Haubenteil 6a mit seinem Rand 6c an dem Rand 6c des inneren Haubenteils 6b an. Die beiden Haubenteile 6a, 6b begrenzen somit einen flachzylindrischen Hohlraum zur Aufnahme der Seilrolle 2. Die winkelrichtige Montage der beiden Haubenteile 6a, 6b zueinander wird durch eine Zentrierhülse erleichtert, die in entsprechende Aussparungen in den Rändern 6c der Haubenteile 6a, 6b eingelegt wird.The FIG. 1 shows a perspective view of a rope bottle according to the invention designed as a bottom bottle 1, the two about pulleys 2 (see also FIG. 2 ) guided pairs of load cables 3 is suspended from a cable, not shown. In the FIG. 1 only three of the respectively out of the bottom block 1 outgoing entering dreams of the two pairs of load cables 3 are shown, since a fourth of the bottom block 1 is hidden. The lower block 1 consists essentially of a central connecting element 4 with two laterally mounted thereon rope pulleys 2 and a hook suspended from below hook 5. The load hook 5 is rotatably mounted about a vertical axis in a recess of the connecting element 4 via a thrust bearing, not shown. The coaxially arranged and spaced apart on the connecting element 4 pulleys 2 are each surrounded by covers 6, which are seen in the axial direction of the pulley 2 divided into an outer hood part 6a and an inner hood part 6b in the plane of the pulley 2. The two hood parts 6a, 6b are identical. The outer hood part 6a and the inner hood part 6b are each formed as flat annular disks with an outer circumferential and arcuate edge 6c. The outer hood part 6a and the inner hood part 6b are thus dish-shaped or dish-shaped. In the assembled state, the outer hood part 6a abuts with its edge 6c on the edge 6c of the inner hood part 6b. The two hood parts 6a, 6b thus limit a flat cylindrical cavity for receiving the pulley 2. The correct angle mounting the two hood parts 6a, 6b to each other is facilitated by a centering, which is inserted into corresponding recesses in the edges 6c of the hood parts 6a, 6b.

In den Abdeckhauben 6 (siehe auch Figur 4) sind jeweils zwei Ein- und Austrittsöffnungen 7 für den Einlauf des Lastseils 3 auf die Seilrolle 2 und dessen Ablauf von der Seilrolle 2 angeordnet. Diese Ein- und Austrittsöffnungen 7 weisen in Umfangsrichtung der Seilrolle 2 beziehungsweise der Abdeckhaube 6 gesehen eine Länge L auf, die einem Mehrfachen des Durchmessers des Lastseils 3 entspricht und sind somit schlitzförmig. Die Länge L entspricht einem Sechstel des Umfangs der Abdeckhaube 6. Diese Länge L ist erforderlich, da - wie in der Beschreibungseinleitung zu dem Stand der Technik bereits erläutert - während des Betriebs des Seilzugs der Winkel zwischen den Trumen der Lastseile 3 variiert und somit der Ablaufpunkt 10 (siehe Figur 2) des Lastseils 3 von der Seilrolle 2 sich ändert. Die vorhandene Länge L der Ein- und Austrittsöffnungen 7 verhindert somit, dass das Lastseil 3 an den Rändern 7a der Ein- und Austrittsöffnungen 7 vorbeischleift und hierdurch die Abdeckhauben 6 oder die Lastseile 3 Schaden nehmen können.In the covers 6 (see also FIG. 4 ) are in each case two inlet and outlet openings 7 for the inlet of the load rope 3 on the pulley 2 and its outlet from the pulley 2 are arranged. These inlet and outlet openings 7 have in the circumferential direction of the pulley 2 and the cover 6 seen a length L, which corresponds to a multiple of the diameter of the load cable 3 and are thus slit-shaped. The length L corresponds to one sixth of the circumference of the cover 6. This length L is required because - as already explained in the introduction to the prior art - during operation of the cable the angle between the runs of the load cables 3 varies and thus the flow point 10 (see FIG. 2 ) of the load rope 3 of the pulley 2 changes. The existing length L of the inlet and outlet openings 7 thus prevents the load rope 3 at the edges 7a of the inlet and outlet openings 7 vorbeischleift and thereby the covers 6 or the load cables 3 can take damage.

Die somit verhältnismäßig großen Ein- und Austrittsöffnungen 7 sind jeweils mit einem Abdeckelement 8 zumindest teilweise verschlossen, das eine Öffnung 9 für die Durchführung des Lastseils 3 von der Seilrolle 2 oder zu der Seilrolle 2 aufweist. In der abgesenkten Position der Unterflasche 1, in der ein Bediener mit der Unterflasche 1 arbeitet, sind die Ein- und Austrittsöffnungen 7 jeweils vollständig von dem Abdeckelement 8 verschlossen. Wenige Meter vor der höchsten angehobenen Stellung der Unterflasche 1, wenn die Trume der Lastseile 3 sich dann spreizen, werden die Abdeckelemente 8 in Umfangsrichtung U nach unten verschoben und geben jeweils einen oberen Teil der Ein- und Austrittsöffnungen 7 frei. Da in der angehobenen Stellung kein Bediener mit der Unterflasche 1 arbeitet, ist in Hinblick auf die Sicherheit, die teilweise Freigabe der Ein- und Austrittsöffnung 7 unbedenklich.The thus relatively large inlet and outlet openings 7 are each at least partially closed with a cover 8, which has an opening 9 for the implementation of the load cable 3 of the pulley 2 or to the pulley 2. In the lowered position of the lower block 1, in which an operator works with the lower bottle 1, the inlet and outlet openings 7 are each completely closed by the cover 8. A few meters before the highest raised position of the lower block 1, when the dreams of the load cables 3 are then spreading, the cover elements 8 are moved in the circumferential direction U downwards and each release an upper part of the inlet and outlet openings 7. Since no operator works in the raised position with the lower bottle 1, in terms of safety, the partial release of the inlet and outlet openings 7 is safe.

Die Öffnung 9 für das Lastseil 3 ist geringfügig größer als der Durchmesser des Lastseils 3 und weist einen rechteckigen Querschnitt mit gerundeten Ecken auf, dessen Breite und Länge in einem Verhältnis von 2:1 bis 3:1 zu dem Durchmesser des Lastseils 3 stehen. Hierdurch wird erreicht, dass für den Bediener die Gefahr des Hineinziehens seiner Finger oder Hände durch das einlaufende Lastseil 3 in die Ein-und Austrittsöffnungen 7 beträchtlich verringert wird. Um der zuvor beschriebenen Tatsache Rechnung zu tragen, dass sich während des Betriebs der Unterflasche 1, d.h. beim Heben und Senken, der Ablaufpunkt 10 des Lastseils 3 von der Seilrolle 2 ändert, ist das Abdeckelement 8 in Umfangsrichtung U der Abdeckhaube 6 zwischen einer oberen und einer unteren Endpositionen hin und her verschiebbar.The opening 9 for the load rope 3 is slightly larger than the diameter of the load rope 3 and has a rectangular cross section with rounded corners whose width and length are in a ratio of 2: 1 to 3: 1 to the diameter of the load rope 3. This ensures that the risk of the operator Pulling his fingers or hands by the incoming load rope 3 in the inlet and outlet openings 7 is considerably reduced. To take account of the fact described above, that changes during operation of the lower block 1, ie during lifting and lowering, the drain point 10 of the load cable 3 of the pulley 2, the cover 8 in the circumferential direction U of the cover 6 between an upper and a lower end positions back and forth.

Das Abdeckelement 8 besteht im Wesentlichen aus einer entsprechend der Ränder 6c der Abdeckhauben 6 kreisförmig gebogenen oberen Grundleiste 8a, die flächig auf der Außenfläche 6d der Haubenteile 6a, 6b im Bereich der Ränder 6c der Haubenteile 6a, 6b aufliegt. Die Grundleiste 8a deckt somit jeweils die Ein- und Austrittsöffnungen 7 ab. In Umfangsrichtung U der Abdeckhaube 6 und beginnend von einem unteren Ende des Abdeckelements 8 gesehen erweitert sich die Grundleiste 8a etwa ab deren Mitte in der Art, dass ein Führungsbereich 8b für das Lastseil 3 in Form eines im Wesentlichen rechtwinkligen Dreiecks entsteht, dessen entsprechend dem Rand 6c der Haubenteile 6a, 6b gekrümmte Hypotenuse von der Grundleiste 8a gebildet wird. Außerhalb des Führungsbereichs 8b ist die Grundleiste 8a flach und leistenförmig ausgebildetThe cover element 8 consists essentially of a correspondingly to the edges 6c of the cover 6 circular curved upper base bar 8a, the surface on the outer surface 6d of the hood parts 6a, 6b in the region of the edges 6c of the hood parts 6a, 6b rests. The base strip 8a thus covers each of the inlet and outlet openings 7. As seen in the circumferential direction U of the cover 6 and starting from a lower end of the cover 8, the base strip 8a extends approximately from the center in such a way that a guide portion 8b for the load rope 3 in the form of a substantially right triangle, corresponding to the edge 6c of the hood parts 6a, 6b curved hypotenuse is formed by the base strip 8a. Outside the guide region 8b, the base strip 8a is flat and strip-shaped

Auch ist aus der Figur 1 ersichtlich, dass die Öffnung 9 für das Lastseil 3 in dem Abdeckelement 8 als Kanal 9a ausgebildet ist, der sich von der Grundleiste 8a zu einer oberen der beiden äußeren Kathetenseiten des Führungsbereichs 8b erstreckt. Die Längserstreckung des Kanals 9a verläuft in der Ebene der Seilrolle 2 in einem Winkel von 90° zu einer durch den Ablaufpunkt 10 des Lastseils 3 von der Seilrolle 2 und dem Mittelpunkt M der Seilrolle 2 verlaufenden gedachten Geraden.Also is from the FIG. 1 It can be seen that the opening 9 for the load rope 3 is formed in the cover 8 as a channel 9a extending from the base bar 8a to an upper of the two outer Kathetenseiten the guide portion 8b. The longitudinal extent of the channel 9a extends in the plane of the pulley 2 at an angle of 90 ° to an imaginary line passing through the drain point 10 of the load rope 3 from the pulley 2 and the center M of the pulley 2.

Des Weiteren ist der Figur 1 zu entnehmen, dass die Unterflasche 1 für eine leichtere Handhabung durch den Bediener eine nach oben offene und horizontal verlaufende Griffmulde 11 im Bereich des Verbindungselements 4 aufweist, dessen Breite dem Abstand zwischen den beiden Abdeckhauben 6 entspricht.Furthermore, the FIG. 1 can be seen that the lower block 1 for easier handling by the operator has an upwardly open and horizontally extending recessed grip 11 in the region of the connecting element 4, whose width corresponds to the distance between the two covers 6.

Ferner ist in der Figur 1 angedeutet, dass das Abdeckelement 8 in ein erstes Abdeckteil 8f und ein zweites Abdeckteil 8g geteilt ist. Diese Teilung ist im Führungsbereich 8b des Abdeckelements 8 vorgenommen und in einer zur Radialrichtung der Seilrolle 2 parallelen und den Mittelpunkt M der Seilrolle 2 schneidenden Ebene. Diese Ebene ist nicht mittig zum Abdeckelement 8 ausgerichtet sondern bezogen auf die Breite des Abdeckelements 8 etwa im Verhältnis von 2/3 zu 1/3 der Breite des Abdeckelements 8. Hierbei weist das erste Abdeckteil 8f eine Breite von 2/3 der Breite des Abdeckelements 8 auf. Entsprechender Weise, d.h. auf Grund der Lage der Schnittebene in der Mitte der Breite des Abdeckelements 8, ist in den Figuren 2 und 3 nur das erste Abdeckteil 8f im Schnitt dargestellt. Die Teilung des Abdeckelements 8 ermöglicht, in einem ersten Montageschritt das erste Abdeckteil 8f in die Ein- und Austrittsöffnung 7 einzuführen und in einem zweiten Montageschritt über ein Einführen des zweiten Abdeckteils 8g in die Ein- und Austrittsöffnung 7 dort zu verriegeln. Am Ende der Montage wird das zweite Abdeckteil 8g lösbar an dem ersten Abdeckteil 8f befestigt.Furthermore, in the FIG. 1 indicated that the cover 8 is divided into a first cover 8f and a second cover 8g. This division is made in the guide area 8b of the cover 8 and in a direction parallel to the radial direction of the pulley 2 and the center M of the pulley. 2 cutting level. This plane is not centered to the cover 8 but based on the width of the cover 8 approximately in the ratio of 2/3 to 1/3 of the width of the cover 8. Here, the first cover 8f has a width of 2/3 of the width of the cover 8 on. Correspondingly, ie due to the position of the cutting plane in the middle of the width of the cover 8, is in the Figures 2 and 3 only the first cover 8f shown in section. The division of the cover element 8 makes it possible to insert the first cover part 8f into the inlet and outlet opening 7 in a first assembly step and to lock it there in a second assembly step by inserting the second cover part 8g into the inlet and outlet opening 7. At the end of assembly, the second cover member 8g is detachably attached to the first cover member 8f.

Die Figuren 2 und 3 zeigen jeweils eine Schnittansicht durch eine der beiden Seilrollen 2 mit ihrer angrenzenden Abdeckhaube 6 und den Abdeckelementen 8 in zwei unterschiedlichen Winkelstellungen der Trume der Lastseile 3 zueinander und somit zwei unterschiedliche Verschiebestellungen der Abdeckelemente 8 in der Seilöffnung 7. Aus Gründen der Übersichtlichkeit sind die Lastseile 3 nicht dargestellt.The Figures 2 and 3 each show a sectional view through one of the two pulleys 2 with its adjacent cover 6 and the cover 8 in two different angular positions of the strands of the load cables 3 to each other and thus two different displacement positions of the cover 8 in the cable opening 7. For reasons of clarity, the load cables. 3 not shown.

In der Figur 2 sind die beiden Abdeckelemente 8 jeweils in einer sogenannten Normalstellung in den Ein- und Austrittsöffnungen 7 angeordnet, in der die Unterflasche 1 senkrecht unter dem Seilzug hängt und die beiden Trume des Lastseils 3 nahezu parallel zueinander verlaufen. In dieser Normalstellung hängt die Unterflasche 1 im Bereich eines Bedieners, der die Unterflasche 1 vorzugsweise an dem Griff 11 führt und/oder dirigiert. Hierbei sind die Ein- und Austrittsöffnungen 7 jeweils vollständig von den Abdeckelementen 8 überdeckt. Es ist ersichtlich, dass der Kanal 9a der Öffnung 9 nahezu senkrecht und somit parallel zu den Lastseilen 3 verläuft. Hierbei legt sich auf Grund der Schwerkraft die nach innen zur Seilrolle 2 gelegene Innenwand des Kanals 9a an der dem gegenüberliegenden Lastseil 3 zugewandte Seite des Lastseils 3 an, da das Abdeckelement 8 relativ reibungsarm in der Ein- und Austrittsöffnung 7 in Umfangsrichtung der Abdeckhaube 6 verschiebbar geführt ist. Die auftretende Reibung zwischen dem Lastseil 3 und dem Kanal 9a des Abdeckelements 8 ist gering, da das Abdeckelement 8 sehr leicht ist. Außerdem ist das Abdeckelement 8 als Kunststoffspritzgussteil aus einem Werkstoff mit einer hohen Verschleißfestigkeit hergestellt.In the FIG. 2 the two cover elements 8 are each arranged in a so-called normal position in the inlet and outlet openings 7, in which the bottom block 1 is suspended vertically under the cable and the two strands of the load rope 3 are almost parallel to each other. In this normal position, the lower block 1 hangs in the area of an operator who preferably guides and / or directs the lower block 1 on the handle 11. Here, the inlet and outlet openings 7 are each completely covered by the cover 8. It can be seen that the channel 9a of the opening 9 runs almost vertically and thus parallel to the load cables 3. In this case, due to gravity, the inner wall of the channel 9a located inwardly towards the pulley 2 engages the side of the load rope 3 facing the opposite load rope 3, since the cover element 8 is displaceable relative to the inlet and outlet openings 7 in the circumferential direction of the cover 6 is guided. The occurring friction between the load cable 3 and the channel 9a of the cover 8 is low, since the cover 8 is very light. In addition, the cover 8 is made as a plastic injection molded part made of a material having a high wear resistance.

Die Figur 3 zeigt die beiden Abdeckelemente 8 in einer von der in Figur 2 dargestellten Normalstellung abweichenden Verschiebestellung, in der die beiden Trume der Lastseile 3 etwa einen Winkel von 50° einschließen und somit sich die beiden Abdeckelemente 8 in einer unteren Verschiebestellung befinden. Die ist der Fall, wenn die Unterflasche 1 unter der Krankatze in der höchsten Stellung hängt und somit außerhalb des Zugriffs eines Bedieners. In der Verschiebestellung ist jeweils ein oberer Teil der Ein- und Austrittsöffnungen 7 nicht von dem Abdeckelement 8 überdeckt, da es aus Sicherheitsüberlegungen nicht notwendig ist. Grundsätzlich könnte das Abdeckelement 8 entsprechend verlängert werden, damit in Normalstellung und auch in Verschiebestellung die Ein- und Austrittsöffnungen 7 jeweils vollständig überdeckt sind.The FIG. 3 shows the two cover elements 8 in one of the in FIG. 2 shown normal position deviating displacement position in which the two strands of the load cables 3 include an angle of approximately 50 ° and thus the two cover elements 8 are in a lower displacement position. This is the case when the bottom block 1 hangs in the highest position under the trolley and thus out of the reach of an operator. In the displacement position, in each case an upper part of the inlet and outlet openings 7 is not covered by the cover element 8, since it is not necessary for safety reasons. In principle, the cover 8 could be extended accordingly, so that in the normal position and also in the displacement position, the inlet and outlet openings 7 are each completely covered.

In der Figur 4 ist eine einzelne Abdeckhaube 6 ohne ein Abdeckelement 8 in einer Ausrichtung einer senkrecht an dem Seilzug hängenden Unterflasche 1 dargestellt. Als Ansichtsebene ist die Vorder- beziehungsweise Rückseite der Unterflasche 1 und senkrecht zur Drehachse der Seilrolle 2 gewählt worden, so dass eine der Ein- und Austrittsöffnungen 7 gut zu erkennen ist. Die Ein- und Austrittsöffnung 7 hat die Form eines lang gestreckten Rechtecks mit abgerundeten Enden. Die Breite B der Ein- und Austrittsöffnung 7 entspricht etwa dem 2- bis 3-fachen des Durchmesser D des Lastseils 3 und die Länge der Ein- und Austrittsöffnung 7 entspricht etwa dem 10- bis 15-fachen des Durchmesser D des Lastseils 3 beziehungsweise etwa ein Sechstel des Umfangs der Abdeckhaube 6.In the FIG. 4 a single cover 6 is shown without a cover 8 in an orientation of a vertically hanging on the cable lower block 1. As a plane of view, the front and rear of the bottom block 1 and has been selected perpendicular to the axis of rotation of the pulley 2, so that one of the inlet and outlet openings 7 is clearly visible. The inlet and outlet opening 7 has the shape of an elongated rectangle with rounded ends. The width B of the inlet and outlet opening 7 corresponds approximately to 2 to 3 times the diameter D of the load rope 3 and the length of the inlet and outlet opening 7 corresponds approximately to 10 to 15 times the diameter D of the load rope 3 or about one sixth of the circumference of the cover 6th

Auch zeigt die Figur 4 in Verbindung mit Figur 2 oder 3, dass sich bezogen auf die Umfangsfläche der Abdeckhaube 6 und der Annahme, dass an der obersten Stelle der Abdeckhaube 6 der Winkel auf 0° gesetzt wird, die erste Ein- und Austrittsöffnung 7 etwa bei 40° beginnt und bis 100° läuft, die zweite Ein- und Austrittsöffnung 7 auf der gegenüberliegenden Seite im Bereich von 260° beginnt und bei 320° endet. Das Abdeckelement 8 ist in Bezug auf seine Länge so bemessen, dass in dessen extrem nach oben verschobenen Normalstellung das untere Ende der Ein- und Austrittsöffnungen 7 noch überdeckt wird. In der extrem nach unten verschobenen Verschiebestellung wird das obere Ende der Ein- und Austrittsöffnungen 7 nicht mehr überdeckt. In Bezug auf etwaige Verletzungsgefahren für den Bediener ist dieser obere Bereich jedoch üblicher Weise nicht im Bereich des Zugriffs und kann somit offen bleiben.Also shows the FIG. 4 combined with FIG. 2 or 3 in that, based on the peripheral surface of the cover 6 and the assumption that the angle is set to 0 ° at the uppermost point of the cover 6, the first inlet and outlet opening 7 starts at about 40 ° and runs to 100 °, the second Inlet and outlet opening 7 starts on the opposite side in the range of 260 ° and ends at 320 °. The cover 8 is dimensioned with respect to its length so that in its extremely shifted upward normal position, the lower end of the inlet and outlet openings 7 is still covered. In the extremely downwardly shifted displacement position, the upper end of the inlet and outlet openings 7 is no longer covered. However, with regard to any risk of injury to the operator, this upper area is usually not in the area of access and thus can remain open.

Die Figur 5 zeigt die Ansicht gemäß Figur 4, jedoch in einer senkrechten Schnittansicht, so dass das Abdeckelement 8 im Bereich seines Kanals 9a geschnitten wird. In Bezug auf den Kanal 9a ist zu erkennen, dass dieser sich quer zur Umfangsrichtung der Abdeckhaube 6 ausgehend von der Seilrolle 2 nach oben hin erweitert. Hierdurch kann das Lastseil 3 auch seitlich ausgelenkt werden, ohne dass eine zu starke Reibung zwischen dem Lastseil 3 und der Innenwand des Kanals 9a stattfindet. Wie aus den Figuren 2 und 3 ersichtlich ist, erweitert sich der Kanal 9a hingegen in Umfangsrichtung kaum, da hier eine Seilauslenkung über die Verschiebung der Abdeckelement 8 in der Ein- und Austrittsöffnung 7 kompensiert wird.The FIG. 5 shows the view according to FIG. 4 but in a vertical sectional view, so that the cover 8 is cut in the region of its channel 9a. With respect to the channel 9a, it can be seen that this widens transversely to the circumferential direction of the cover 6, starting from the pulley 2 upwards. In this way, the load cable 3 can also be deflected laterally, without too much friction between the load cable 3 and the inner wall of the channel 9a takes place. Like from the Figures 2 and 3 can be seen, the channel 9a, however, widens hardly in the circumferential direction, since a cable deflection on the displacement of the cover 8 in the inlet and outlet opening 7 is compensated.

Des Weiteren zeigt die Figur 5, dass das Abdeckelement 8 die Ränder der Ein- und Austrittsöffnung 7 außen mit seiner Grundleiste 8a überdeckt, die am oberen Ende als dreieckförmiger Führungsbereich 8b ausgebildet ist. Im Bereich des Führungsbereichs 8b ist die Grundleiste 8a über ihre Stegleiste 8d mit der Halteleiste 8c verbunden, die die Ränder 6c der Ein- und Austrittsöffnungen 7 hintergreift (siehe Figur 6). Dementsprechend ist die Halteleiste 8c über die mittige Stegleiste 8d an der Unterseite der Grundleiste 8a befestigt, so dass das Abdeckelement 8 in diesem Bereich einen H-förmigen Querschnitt aufweist. Hierdurch ist das Abdeckelement 8 in Umfangsrichtung der Abdeckhaube 6 verschiebbar an dieser. Die Halteleiste 8c liegt somit mit ihrer dem Rand 6c zugewandten Führungsfläche 8e an der Innenfläche 6e des Rands 6c an. Im Bereich der Öffnung 9 entfällt die Stegleiste 8d und die Halteleiste 8c ist über die Stegleiste 8d vor und hinter der Öffnung 9 gehalten. Der Figur 2 ist zu entnehmen, dass sich die Halteleiste 8c sich über einen Bereich von etwa 30° erstreckt. Der sich an den Führungsbereich 8b nach unten anschließende Teil der Grundleiste 8a ist nicht mit einer Halteleiste 8c und einer Stegleiste 8d versehen. Eine Führung erfolgt über das restliche Abdeckelement 8 mit seiner Halteleiste 8c im Bereich des Führungsbereichs 8b.Furthermore, the shows FIG. 5 in that the cover element 8 covers the edges of the inlet and outlet opening 7 externally with its base strip 8a, which is formed at the upper end as a triangular guide region 8b. In the region of the guide region 8b, the base strip 8a is connected via its web bar 8d to the retaining strip 8c, which engages behind the edges 6c of the inlet and outlet openings 7 (see FIG FIG. 6 ). Accordingly, the retaining strip 8c is attached via the central web strip 8d to the underside of the base strip 8a, so that the cover element 8 has an H-shaped cross section in this region. As a result, the cover 8 is displaceable in the circumferential direction of the cover 6 at this. The retaining strip 8c thus lies with its edge 6c facing the guide surface 8e on the inner surface 6e of the edge 6c. In the area of the opening 9, the web strip 8d is omitted and the retaining strip 8c is held in front of and behind the opening 9 via the web strip 8d. Of the FIG. 2 it can be seen that the retaining strip 8c extends over a range of about 30 °. The part of the base strip 8a that adjoins the guide area 8b downwards is not provided with a retaining strip 8c and a web strip 8d. A guide takes place via the remaining cover element 8 with its retaining strip 8c in the region of the guide region 8b.

Die Figur 6 stellt eine weitere Schnittansicht von Figur 4 dar, wobei der Schnitt durch die Achse 13 der Seilrolle 2 gelegt ist. Die Achse 13 ist Bestandteil des Verbindungselements 4. Auf der Achse 13 ist über ein Lager 14 die Seilrolle 2 gelagert. Die Achse 13 beziehungsweise das Verbindungselement 4 dient dazu, die kreisförmigen inneren und äußeren Haubenteile 6a, 6b, die als Blechformteile ausgebildet sind, abzustützen. Das innere als erstes auf die Achse aufgeschobene Haubenteil 6b stützt sich an einer die Achse 13 begrenzenden Schulter des Verbindungselements 4 ab, anschließend folgt das Lager 14 und dann das äußere Haubenteil 6a, das über einen Sicherungsring 15 auf der Achse 13 gehalten ist. Außerdem ist das ringförmige äußere Haubenteil 6a im Bereich der Achse 13 durch einen kreisrunden Deckel 19 verschlossen. Des Weiteren ist zu erkennen, dass die Grundleiste 8a im Querschnitt leistenförmig ist.The FIG. 6 represents another sectional view of FIG. 4 is, wherein the section through the axis 13 of the pulley 2 is placed. The axis 13 is part of the connecting element 4. On the axis 13, the pulley 2 is mounted on a bearing 14. The axis 13 or the connecting element 4 serves to the circular inner and outer hood parts 6a, 6b, as sheet metal parts are designed to support. The inner hood part 6b, which is first pushed onto the axle, is supported on a shoulder of the connecting element 4 delimiting the axle 13, followed by the bearing 14 and then the outer hood part 6a, which is held on the axle 13 via a securing ring 15. In addition, the annular outer hood part 6a is closed in the region of the axis 13 by a circular cover 19. Furthermore, it can be seen that the base strip 8a is strip-shaped in cross-section.

In der Figur 7 ist eine perspektivische Ansicht eines ersten Abdeckteils 8f des Abdeckelements 8 außerhalb einer Unterflasche 1 und somit in einen nicht montierten Zustand dargestellt. Wie zuvor beschrieben besteht das erste Abdeckteil 8f im Wesentlichen aus einer kreisbogenförmigen Grundleiste 8a, die im Einbauzustand an der Außenfläche 6d der Abdeckhaube 6 aufliegt. Etwa ab der Mitte des Abdeckelements 8 gesehen ist der obere Teil der Grundleiste 8a zu einem dreieckförmigen Führungsbereich 8b verbreitert beziehungsweise geht in diesen über. Der untere Teil der Grundleiste 8a bleibt leistenförmig und beginnt in Umfangsrichtung des Abdeckelements 8 gesehen in der Mitte im Querschnitt u-förmig, in dem sich Randleisten 8h seitlich an die Ränder der Grundleiste 8a anschließen. Diese Randleisten 8h nehmen in Richtung des unteren Endes der Grundleiste 8a ab und sind am Ende der Grundleiste 8a nicht mehr vorhanden. Zusätzlich sind an der Innenseite der Grundleiste 8a parallel und mit Abstand zueinander verlaufende Verstärkungsrippen 8i für die Grundleiste 8a vorgesehen, um ein sicheres Abdecken der Ein- und Austrittsöffnung 7 zu gewährleisten und Material zu sparen. Die Breite der Verstärkungsrippen 8i nimmt wie die der Randleisten 8h in Richtung des unteren Endes der Grundleiste 8a ab.In the FIG. 7 Fig. 3 is a perspective view of a first cover part 8f of the cover member 8 outside of a lower bottle 1 and thus in an unassembled state. As described above, the first cover part 8f essentially consists of an arcuate base strip 8a, which rests in the installed state on the outer surface 6d of the cover 6. As seen from the middle of the cover 8, the upper part of the base strip 8a widens or merges into a triangular guide region 8b. The lower part of the base strip 8a remains strip-shaped and begins in the circumferential direction of the cover 8 seen in the middle in cross-section U-shaped, in which the edge strips 8h laterally adjoin the edges of the base strip 8a. These edge strips 8h decrease in the direction of the lower end of the base strip 8a and are no longer present at the end of the base strip 8a. In addition, reinforcing ribs 8i extending parallel to one another and spaced from one another on the inside of the base strip 8a are provided for the base strip 8a in order to ensure reliable covering of the inlet and outlet openings 7 and to save material. The width of the reinforcing ribs 8i decreases like that of the edge strips 8h in the direction of the lower end of the base strip 8a.

Im Führungsbereich 8b ist die Öffnung 9 für das Lastseil 3 erkennbar. Im Bereich der ersten Trennfläche 8j des ersten Abdeckteils 8f sind flache zylinderförmige Noppen 12 rasterförmig angeordnet, die jeweils aus der ersten Trennfläche 8j hervor stehen. Auch sind in dem Führungsbereich 8b rechts und links neben der Öffnung 9 jeweils eine zylindrische Bohrung 16 für eine Schraube 17 (siehe Figur 9d) vorgesehen. Die Bohrung 16 verläuft mit ihrer Längserstreckung parallel zu der Drehachse der Seilrolle 2.In the guide area 8b, the opening 9 for the load rope 3 can be seen. In the region of the first parting surface 8j of the first cover part 8f, flat cylindrical nubs 12 are arranged in a grid shape, which projects from the first parting surface 8j. Also, in the guide area 8b to the right and left of the opening 9 are each a cylindrical bore 16 for a screw 17 (see FIG. 9d ) intended. The bore 16 extends with its longitudinal extent parallel to the axis of rotation of the pulley. 2

Zusätzlich zeigt die Figur 7, dass unten an der Grundleiste 8a sich im Bereich angrenzend an die Öffnung 9 und in Umlaufrichtung der Abdeckhaube 6 sich erstreckend die Stegleiste 8d mit der Halteleiste 8c anschließen. Im Bereich der Öffnung 9 ist die Stegleiste 8d unterbrochen, die Halteleiste 9c ist durchgehend. Es ist ersichtlich, dass die Halteleiste 8c nur etwa 1/3 der Länge des Abdeckelements 8 aufweist und somit die Führung und Verschiebung des Abdeckelements 8 in Umfangsrichtung der Abdeckhaube 6 möglich ist.In addition, the shows FIG. 7 that at the bottom of the base 8a in the area adjacent to the opening 9 and in the circumferential direction of the cover 6 extending the web bar 8 d with the retaining strip 8 c connect. In the area of the opening 9, the web bar 8d is interrupted, the retaining strip 9c is continuous. It can be seen that the retaining strip 8c has only about 1/3 of the length of the cover 8 and thus the leadership and displacement of the cover 8 in the circumferential direction of the cover 6 is possible.

Da das zweite Abdeckteil 8g nicht auf die erste Trennfläche 8j aufgesetzt ist, ist die Öffnung 9 nicht rohrförmig sondern offen rinnenförmig.Since the second cover part 8g is not placed on the first separation surface 8j, the opening 9 is not tubular but open groove-shaped.

Die Figur 8 zeigt eine perspektivische Ansicht eines zweiten Abdeckteils 8g des Abdeckelements 8, das vorgesehen ist, das erste Abdeckteil 8f nach einer entsprechenden Montage zu dem Abdeckelement 8 mit einer rohrförmigen Öffnung 9 zu komplettieren. In Bezug auf das erste Abdeckteil 8f in Figur 7 ist das zweite Abdeckteil 8g spiegelverkehrt dargestellt, um auch eine Ansicht auf eine zweite Trennfläche 8k zu erhalten. Im montierten Einbauzustand liegen die erste Trennfläche 8j des ersten Abdeckteils 8f und die zweite Trennfläche 8k des zweiten Abdeckteils 8g aufeinander. Um deren Ausrichtung zueinander zu erleichtern und deren Kontakt zueinander zu verbessern, sind in der zweiten Trennfläche 8k rasterförmig angeordnete zylindrische Aussparungen 18 angeordnet, die im montierten Einbauzustand der beiden Abdeckteile 8f, 8g formschlüssig die Noppen 12 der erste Trennfläche 8j aufnehmen. Auch nehmen die Aussparungen 18 im Eingriff mit den Noppen 12 Querkräfte auf und entlasten somit die Schrauben 17. Auch sind wie bei dem ersten Abdeckteil 8f rechts und links neben der Öffnung 9 jeweils eine Bohrung 16 für die Schraube 17 angeordnet. Das zweite Abdeckteil 8g ist von der Form vergleichbar mit dem Führungsbereich 8b also im Wesentlichen dreieckförmig. Wie an dem ersten Abdeckteil 8j ist auch im Bereich der Grundleiste 8a des zweiten Abdeckteils 8g über eine Stegleiste 8d eine Halteleiste 8c angeordnet. Die Stegleiste 8d und die Halteleiste 8c grenzen an die Öffnung 9 an und erstrecken sich hiervon ausgehend nur über einen Teil der Grundleiste 8a des zweiten Abdeckteils 8g. Im Bereich der Öffnung 9 ist die Stegleiste 8d unterbrochen. Im Bereich der Stegleiste 8d und der Halteleiste 8c sind das erste Abdeckteil 8f und das zweite Abdeckteil 8g so ausgebildet, dass sich im montierten Einbauzustand die jeweiligen Teile der Stegleiste 8d und der Halteleiste 8c des ersten Abdeckteil 8f und des zweiten Abdeckteils 8g zu einer kompletten Halteleiste 8c und einer kompletten Stegleiste 8d ergänzen, die dann den rechten und den linken Rand 7a der Ein- und Austrittsöffnung 7 hintergreifen.The FIG. 8 shows a perspective view of a second cover 8g of the cover 8, which is intended to complete the first cover 8f for a corresponding assembly to the cover 8 with a tubular opening 9. With respect to the first cover part 8f in FIG FIG. 7 the second cover part 8g is shown mirror-inverted in order to also obtain a view of a second parting surface 8k. In the mounted state of installation, the first separation surface 8j of the first cover part 8f and the second separation surface 8k of the second cover part 8g are in contact with each other. In order to facilitate their alignment with one another and to improve their contact with one another, cylindrical recesses 18 are arranged in the second separating surface 8k and receive the nubs 12 of the first separating surface 8j in a form-fitting manner in the fitted state of installation of the two cover parts 8f, 8g. Also take the recesses 18 in engagement with the nubs 12 transverse forces and thus relieve the screws 17. Also, as in the first cover 8f right and left of the opening 9 each have a bore 16 for the screw 17 is arranged. The second cover part 8g is thus substantially triangular in shape, similar to the guide area 8b. As on the first cover part 8j, a retaining strip 8c is also arranged in the region of the base strip 8a of the second cover part 8g via a web strip 8d. The web strip 8d and the retaining strip 8c adjoin the opening 9 and extend from this only over a part of the base strip 8a of the second cover part 8g. In the area of the opening 9, the web bar 8d is interrupted. In the area of the web strip 8d and the retaining strip 8c, the first cover part 8f and the second cover part 8g are formed so that the respective parts of the web strip 8d and the retaining strip 8c of the first cover part 8f and the second cover part 8g to a complete retaining strip in the assembled state 8c and a complete web bar 8d complement, which then engage behind the right and left edges 7a of the inlet and outlet opening 7.

In den Figuren 9a bis 9d ist eine Abfolge von perspektivischen Ansichten eines ersten und eines zweiten Abdeckteils 8f, 8g eines Abdeckelements 8 gezeigt, um die einzelnen erforderlichen Schritte für eine Montage des Abdeckelements 8 an der Abdeckhaube 6 einer Unterflasche 1 näher zu erläutern. In einer erstem Montageschritt wird das erste Abdeckteil 8f mit seiner Öffnung 9 auf den Bereich des Lastseils 3 geschoben, der aus der zu verschließenden Ein- und Austrittsöffnung 7 heraustritt (siehe Figur 9a). Zwischen dem Abdeckteil 8f und der Ein- und Austrittsöffnung 7 besteht ein Abstand. Nun wird in einem zweiten Montageschritt das erste Abdeckteil 8f entlang des Lastseils 3 in Richtung des Ein- und Austrittsöffnung 7 geschoben bis die Grundleiste 8a außen auf der Außenfläche 6d der Abdeckhaube 6 zur Auflage kommt. Da die Ein- und Austrittsöffnung 7 breiter als der an dem ersten Abdeckteil 8f befindliche Teil der Halteleiste 8c ist, kann beim Aufschieben die Halteleiste 8c an dem Rand 7 der Ein- und Austrittsöffnung 7 vorbeigleiten in das Innere der Abdeckhaube 6 hinein. Dann wir in einem dritten Montageschritt das auf der Außenfläche 6d der Abdeckhaube 6 ruhende erste Abdeckteil 8f seitlich nach links in eine Montagerichtung M2 geschoben, die parallel zu der Achse 13 der Seilrolle 2 verläuft (siehe Figur 9b). Hierdurch hintergreift der linke Teil der Halteleiste 8c den linken Rand 7a der Ein- und Austrittsöffnung 7 und ist somit in der Ein- und Austrittsöffnung 7 in Radialrichtung der Seilrolle 2 gehalten. Auch ist das erste Abdeckteil 8f hierbei in Richtung des unteren Endes der der Ein- und Austrittsöffnung 7 verschoben, so dass ein oberer Teil der Ein- und Austrittsöffnung 7 frei liegt. In diesen freien oberen Teil der Ein- und Austrittsöffnung 7 wird nun in einem vierten Montageschritt das zweite Abdeckteil 8g eingesetzt, bis die Grundleiste 8a außen auf der Außenfläche 6d der Abdeckhaube 6 zur Auflage kommt (siehe Figur 9c). Da die Ein- und Austrittsöffnung 7 breiter als der an dem zweiten Abdeckteil 8g befindliche rechte Teil der Halteleiste 8c ist, kann bei Aufschieben die Halteleiste 8c an dem Rand 7 der Ein- und Austrittsöffnung 7 vorbeigleiten in das Innere der Abdeckhaube 6 hinein. Dann wird in einem fünften Montageschritt das auf der Außenfläche 6d der Abdeckhaube 6 ruhende zweite Abdeckteil 8f seitlich nach rechts in eine Montagerichtung M3 geschoben, die parallel zu der Achse 13 der Seilrolle 2 verläuft. Hierdurch hintergreift der rechte Teil der Halteleiste 8c den rechten Rand 7a der Ein-und Austrittsöffnung 7. Nun folgt ein sechster Montageschritt, in dem das zweite Abdeckteil 8g entlang der Außenfläche 6d der Abdeckhaube 6 in einer Montagerichtung M4 auf den Führungsbereich 8b des ersten Abdeckteils 8f zu geschoben wird, bis das vordere Ende des zweiten Abdeckteils 8g an dem ersten Abdeckteil 8f zur Anlage kommt. Hierbei hintergreift der rechte Teil der Halteleiste 8c immer noch den rechten Rand 7a der Ein- und Austrittsöffnung 7. In einem siebten Montageschritt werden das rechte und linke Abdeckteil 8f, 8g in einer Montagerichtung M5, die parallel zu Achse der Seilrolle 2 verläuft, aufeinander zu geschoben, so dass die erste und zweite Trennfläche 8j, 8k zur Anlage kommen und die Noppen 12 jeweils in die Aussparungen 18 gleiten (siehe Figur 9d). Die Höhe der Noppen 12 ist so gewählt - etwa 0.5 mm bis 3.0 mm -, dass nach dem Aufeinanderschieben der beiden Abdeckteile 8f, 8g die rechte und auch die linke Halteleiste 8c den Rand 7a der Ein- und Austrittsöffnung 7 sicher hintergreifen und das Abdeckelement 8 mit einem geringen seitlichen Spiel, das mindestens der Höhe der Noppen 12 entspricht, in der Ein- und Austrittsöffnung 7 gehalten ist. Anschließend werden Schrauben 17 in die Bohrungen 16 gesteckt und das zweite Abdeckteil 8g mit dem ersten Abdeckteil 8f verschraubt.In the FIGS. 9a to 9d FIG. 3 shows a sequence of perspective views of a first and a second cover part 8f, 8g of a cover element 8, in order to explain in more detail the individual steps required for mounting the cover element 8 on the cover hood 6 of a lower block 1. In a first assembly step, the first cover 8f is pushed with its opening 9 on the region of the load cable 3, which emerges from the inlet and outlet opening 7 to be closed (see FIG. 9a ). There is a gap between the cover part 8f and the inlet and outlet opening 7. Now, in a second assembly step, the first cover part 8f is pushed along the load cable 3 in the direction of the inlet and outlet opening 7 until the base strip 8a comes to bear on the outside surface 6d of the cover 6 on the outside. Since the inlet and outlet opening 7 is wider than the part of the retaining strip 8c located on the first cover part 8f, the retaining strip 8c can slide past the edge 7 of the inlet and outlet opening 7 into the interior of the covering hood 6 when pushed on. Then, in a third assembly step, the first cover part 8f resting on the outer surface 6d of the cover 6 is pushed laterally to the left in an installation direction M2 which runs parallel to the axis 13 of the cable pulley 2 (see FIG FIG. 9b ). As a result, the left part of the retaining strip 8c engages behind the left edge 7a of the inlet and outlet opening 7 and is thus held in the inlet and outlet opening 7 in the radial direction of the pulley 2. Also, the first cover part 8f is displaced in the direction of the lower end of the inlet and outlet opening 7, so that an upper part of the inlet and outlet opening 7 is exposed. In this free upper part of the inlet and outlet opening 7, the second cover member 8g is now used in a fourth assembly step, until the base strip 8a outside of the outer surface 6d of the cover 6 comes to rest (see FIG. 9c ). Since the inlet and outlet opening 7 is wider than the right part of the retaining strip 8c located on the second cover part 8g, the retaining strip 8c can slide past the edge 7 of the inlet and outlet opening 7 into the interior of the covering hood 6 when pushed on. Then in a fifth assembly step, resting on the outer surface 6d of the cover 6 second cover 8f pushed laterally to the right in a mounting direction M3, which is parallel to the axis 13 of the pulley 2. As a result, the right part of the retaining strip 8c engages behind the right edge 7a of the inlet and outlet opening 7. Now follows a sixth assembly step, in which the second Cover member 8g along the outer surface 6d of the cover 6 is pushed in a mounting direction M4 on the guide portion 8b of the first cover 8f until the front end of the second cover 8g comes to rest on the first cover 8f. Here, the right part of the retaining strip 8c still engages behind the right edge 7a of the inlet and outlet opening 7. In a seventh assembly step, the right and left cover 8f, 8g in a mounting direction M5, which is parallel to the axis of the pulley 2, toward each other pushed, so that the first and second parting surface 8j, 8k come to rest and the nubs 12 each slide into the recesses 18 (see FIG. 9d ). The height of the knobs 12 is chosen - about 0.5 mm to 3.0 mm - that after pushing together the two cover parts 8f, 8g the right and left retaining strip 8c the edge 7a of the inlet and outlet 7 securely engage behind the cover and the eighth with a small lateral clearance, which corresponds at least to the height of the nubs 12, is held in the inlet and outlet opening 7. Subsequently, screws 17 are inserted into the holes 16 and the second cover 8g bolted to the first cover 8f.
