Description

Die Erfindung betrifft eine Befestigungsvorrichtung für das bandförmige Tragmittel eines Hebezeuges mit einem spiralförmig auf eine Bandtrommel aufwickelbaren bandförmigen Tragmittel, das an einem Ende an einem Lastaufnahmemittel und an seinem anderen Ende an der Bandtrommel befestigt ist.The invention relates to a fastening device for the band-shaped suspension element of a hoist with a band-shaped suspension element which can be spirally wound onto a belt drum and which is fastened at one end to a load-carrying means and at the other end to the belt drum.

Beispielsweise bei Kleinhebezeugen ist es bekannt, u.a. auch aus Textilmaterial hergestellte Flachbänder als Tragmittel zu verwenden. Ein solches bandförmiges Tragmittel muß sowohl auf der Bandtrommel als auch an dem Lastaufnahmemittel,etwa einem Hakengeschirr, so befestigt sein, daß mit Sicherheit die geforderte Haltekraft erreicht wird und ein Ausreißen des Tragmittels ausgeschlossen ist. Außerdem soll das Tragmittel bei Verschleiß schnell und einfach ausgewechselt werden können.For example, it is known for small hoists, e.g. to use flat belts made of textile material as a suspension element. Such a band-shaped suspension element must be fastened both on the belt drum and on the load suspension means, such as a hook harness, in such a way that the required holding force is achieved with certainty and tearing out of the suspension element is impossible. In addition, the suspension element should be quick and easy to replace when worn.

Aus der DE-AS 23 12 604 ist ein Kleinhebezeug mit einem spiralförmig auf eine Wickelrolle aufwickelbaren Flachbandtragmittel in Gestalt eines Textilbandes bekannt, das an seinen Enden Schlaufen trägt und an einem Haltebolzen befestigt ist, wobei die Bandtrommel eine mit Eingangsrundungen versehene Ausnehmung zur Aufnahme des Haltebolzens mit der Bandschlaufe aufweist. Zur Bildung dieser .Schlaufen ist das Band an den Enden entsprechend vernäht oder vernietet. Dies bedeutet, daß ein Ersatzband in fixen Längen bereitgehalten werden muß, damit der Austausch in kurzer Zeit erfolgen kann. Außerdem ist es je nach der Beschaffenheit des Bandes schwierig, die Schlaufen mit der notwendigen Haltbarkeit auszubilden, weil die Nieten oder Nähte u.U. ausreißen können.From DE-AS 23 12 604 a small hoist with a spiral flat ribbon support means in the form of a textile ribbon is known, which carries loops at its ends and is attached to a retaining bolt, the ribbon drum one has recesses provided with entrance curves for receiving the retaining bolt with the band loop. To form these loops, the tape is sewn or riveted accordingly at the ends. This means that a replacement tape in fixed lengths must be kept ready so that the replacement can be done in a short time. In addition, depending on the nature of the band, it is difficult to form the loops with the necessary durability because the rivets or seams can tear out.

Bei einer aus der DE-PS 682 482 bekannten gekapselten Blockwinde sind die als Trag- oder Zugmittel verwendeten Flachbänder endseitig mittels Klemmteilen in sich verjüngenden Ausnehmungen des Hakengeschirres festgeklemmt. Solche Ausnehmungen exakt herzustellen ist schwierig und deshalb in der Regel zu teuer. Davon abgesehen besteht die Gefahr, daß sich die Klemmkeile bei unbelastetem Lasthaken lösen, womit die Bandbefestigung unsicher wird.In an encapsulated log winch known from DE-PS 682 482, the flat belts used as support or traction means are clamped at the end by means of clamping parts in tapering recesses in the hook and tackle. It is difficult to produce such recesses exactly and is therefore usually too expensive. That being said, there is a risk that the clamping wedges will come loose when the load hook is not under load, making the strap fastening unsafe.

Schließlich ist noch aus der DE-OS 21 36 540 ein Aufzug bekannt geworden, bei dem als Trag-. mittel ebenfalls ein Band verwendet ist, das endseitig zwischen zwei Halteplatten festgeklemmt ist, wobei eine zusätzliche Sicherung durch Keilstücke vorgesehen ist. Eine solche Konstruktion ist für Kleinhebezeuge wesentlich zu aufwendig; sie hat auch einen zu großen Platzbedarf, um beispielsweise an dem Hakengeschirr vorgesehen werden zu können.Finally, an elevator has become known from DE-OS 21 36 540, in which as a support. medium also a band is used, which is clamped at the end between two holding plates, with additional securing provided by wedge pieces. Such a construction is much too complex for small hoists; it also takes up too much space, for example, to be provided on the hook tackle.

Aufgabe der Erfindung ist es deshalb, eine Befestigungsvorrichtung für das bandförmige Tragmittel, insbesondere bei Kleinhebezeugen, zu schaffen, die sich bei einwandfreier Gewährleistung der erforderlichen Sicherheit gegen Ausreißen durch einen einfachen, platzsparenden und wirtschaftlich herstellbaren Aufbau auszeichnet und ein schnelles, einfaches Auswechseln des Tragmittels bei Verschleiß gestattet.The object of the invention is therefore to provide a fastening device for the band-shaped suspension element, in particular for small hoists, which is characterized by a simple, space-saving and economically producible structure and a quick, simple replacement of the suspension element while ensuring the required security against tearing out properly Wear allowed.

Zur Lösung dieser Aufgabe ist die eingangs genannte Befestigungsvorrichtung erfindungsgemäß dadurch gekennzeichnet, daß das Lastaufnahmemittel und/oder die Bandtrommel eine einen Einführschlitz für das Tragmittel aufweisende, quer zu dem Tragmittel ausgerichtete Bohrung aufweist, in der ein in seiner Querschnittsgestalt der Bohrung angepaßtes Klemmelement angeordnet ist, das in seinem Außendurchmesser mittels eines Spannelementes veränderbar ist und daß das endseitig um das Klemmelement herumgeführte Tragmittel zwischen der Bohrungswand und dem aufgeweiteten Klemmelement verklemmbar ist.To achieve this object, the fastening device mentioned at the outset is characterized according to the invention in that the load-carrying means and / or the tape drum has a bore which has an insertion slot for the suspension means and is oriented transversely to the suspension means and in which a clamping element which is adapted to the cross-sectional shape of the bore is arranged, the outside diameter of which can be changed by means of a tensioning element and that the suspension means guided around the end of the clamping element can be clamped between the bore wall and the expanded clamping element.

Da nach dem Lösen des Spannelementes das Bandende ohne weiteres aus der Bohrung herausgenommen werden kann und das Ende eines neuen Bandes lediglich um das Klemmelement herumgelegt werden muß, ist das Auswechseln des bandförmigen Tragmittels bei dieser Befestigungsvorrichtung besonders einfach. Auf der anderen Seite bewirkt das Klemmelement aber eine großflächige Verklemmung des Bandendes zwischen der Bohrungswand und der Außenumfangsfläche des Klemmelementes, womit eine einwandfreie reibschlüssige Halterung des Bandendes gewährleistet ist.Since after the release of the tensioning element the band end can easily be removed from the bore and the end of a new band only has to be put around the clamping element, the replacement of the band-shaped suspension element is particularly simple with this fastening device. On the other On the side, however, the clamping element causes a large-area jamming of the band end between the bore wall and the outer peripheral surface of the clamping element, which ensures that the band end is held in a frictionally locking manner.

Das Klemmelement kann in einer Ausführungsform eine aufweitbare Klemmbüchse, bspw. aus Metall oder Kunststoffmaterial, aufweisen, die auf ihrer Innenseite wenigstens eine konische Spannfläche trägt, welche auf einer entsprechenden Konusfläche des axial einpreßbaren Spannelementes abgestützt ist. Dabei kann das Spannelement mittels einer axialen Spannschraube in das Klemmelement einpreßbar sein.In one embodiment, the clamping element can have an expandable clamping bush, for example made of metal or plastic material, which carries at least one conical clamping surface on its inside, which is supported on a corresponding conical surface of the axially press-in clamping element. The clamping element can be pressed into the clamping element by means of an axial clamping screw.

Um eine gleichmäßige Aufweitung der Klemmbüchse über ihre Länge bei breiteren Bändern zu gewährleisten, kann das Spannelement zweiteilig ausgebildet sein, wobei seine beiden Teile jeweils eine mit einer entsprechenden konischen Spannfläche des Klemmelementes zusammenwirkende Konusfläche tragen und die beiden Teile des Spannelementes durch die Spannschraube gegensinnig axial bewegbar sind. Ähnlich wie bei einem Spreizdübel lassen sich mit einer solchen Anordnung sehr große radial nach außen gerichtete Kräfte auf die Klemmbüchse übertragen, mit dem Ergebnis, daß das Bandende mit entsprechend großer Kraft zwischen der Bohrungswand und der Klemmbüchse verklemmt wird.In order to ensure a uniform expansion of the clamping sleeve over its length in the case of wider belts, the clamping element can be formed in two parts, both of its parts bearing a conical surface which interacts with a corresponding conical clamping surface of the clamping element and the two parts of the clamping element can be moved axially in opposite directions by the clamping screw are. Similar to an expansion dowel, very large radially outward forces can be transmitted to the clamping bush with such an arrangement, with the result that the band end is clamped with a correspondingly large force between the bore wall and the clamping bush.

Bei einer anderen Ausführungsform, die sich durch besondere Einfachheit auszeichnet, ist die Anordnung derart getroffen, daß das Klemmelement durch wenigstens ein aus elastischem Material bestehendes bolzen- oder hülsenartiges Federelement gebildet ist, das durch das Spannelement axial zusammenpreßbar ist. Das Spannelement selbst kann auch hier wiederum eine das Spannelement durchdringende Spannschraube sein. Beim Festziehen des Spannelementes wird das elastische Material in Axialrichtung zusammengepreßt, so daß es radial ausweicht und mit großer Kraft das Bandende gegen die Bohrungswand anpreßt. Der verhältnismäßig hohe Reibbeiwert des elastischen Materiales des Federelementes trägt dabei zur weiteren Steigerung der erzielbaren Haltekraft für das Bandende bei.In another embodiment, which is characterized by particular simplicity, the arrangement is such that the clamping element is formed by at least one bolt-like or sleeve-like spring element made of elastic material which can be axially compressed by the tensioning element. The tensioning element itself can also be a tensioning screw penetrating the tensioning element. When the tensioning element is tightened, the elastic material is pressed together in the axial direction, so that it deviates radially and presses the band end against the bore wall with great force. The relatively high coefficient of friction of the elastic material of the spring element contributes to a further increase in the achievable holding force for the band end.

In die Bohrung kann ein hülsenartiges Einlegeteil eingesetzt sein, durch das gegebenenfalls auch der Einführungsschlitz zumindest ausgekleidet ist und in dem das Klemmelement angeordnet ist. Dieses vorzugsweise aus Kunststoffmaterial bestehende Einlegeteil schützt das bandförmige Tragmittel an der Stelle, wo es durch den Einführschlitz in die Bohrung eingeführt wird. Außerdem kann durch dieses Einlegteil die maximal erzielbare Haltekraft noch erhöht werden, während an die Toleranzen bei der Herstellung der Bohrung nur geringe Anforderungen gestellt werden müssen.A sleeve-like insert can be inserted into the bore, through which the insertion slot may also be at least lined and in which the clamping element is arranged. This insert, which is preferably made of plastic material, protects the band-shaped suspension element at the point where it is inserted into the bore through the insertion slot. In addition, the maximum achievable holding force can be increased by this insert, while the tolerances in the production of the bore only have to meet minimal requirements.

Im übrigen kann die Wand der Bohrung oder des Einlegeteils eine die Halterung des Endes des Tragmittels verbessernde Profilierung aufweisen.Otherwise, the wall of the bore or of the insert can have a profiling which improves the mounting of the end of the suspension element.

Die praktische Erfahrung hat gezeigt, daß die mit einer solchen Befestigungsvorrichtung erzielbare Haltekraft so groß ist, daß das Tragmittel bis zur Bruchgrenze belastet werden kann, ohne daß seine Enden sich aus der Halterung lösen könnten.Practical experience has shown that the holding force that can be achieved with such a fastening device is so great that the suspension element can be loaded up to the breaking point without its ends being able to come loose from the holder.

Wie bereits erwähnt, kann das Tragmittel bei Verschleiß einfach und schnell ausgewechselt werden, wobei das Ersatzband von einer größeren Vorratsrolle abgeschnitten und ohne zusätzliche endseitige Bearbeitung eingesetzt werden kann. Die ganze Vorrichtung baut sehr klein und kompakt; sie ist einfach und wirtschaftlich herstellbar.As already mentioned, the suspension element can be replaced quickly and easily when worn, the replacement band being cut off from a larger supply roll and being able to be used without additional end processing. The whole device is very small and compact; it is simple and economical to manufacture.

In Fig. 1 ist ein Lastaufnahmemittel eines Kleinhebezeuges in Gestalt eines Lasthakens 1 dargestellt, der in der üblichen Weise drehbar an einem Gehäuse 2 gelagert ist, das seinerseits an einem Tragmittel in Form eines aus Kunststoff-Textilmaterial bestehenden Bandes 3 befestigt ist. Das Band 3 ist anderenends an einer in Fig. 4 im Ausschnitt veranschaulichten Bandtrommel 4 verankert, auf der es in an sich bekannter Weise spiralförmig aufgewickelt werden kann.In Fig. 1, a load suspension device of a small lifting device is shown in the form of a load hook 1, which is rotatably mounted in the usual manner on a housing 2, which in turn is attached to a suspension element in the form of a band 3 made of plastic-textile material. The tape 3 is anchored at the other end to a tape drum 4 illustrated in FIG. 4, on which it can be spirally wound in a manner known per se.

Die Verbindung der Enden des Bandes 3 mit dem Gehäuse 2 und der Bandtrommel 4 geschieht jeweils mit einer Befestigungsvorrichtung 5, deren Aufbau in mehreren Ausführungsformen insbesondere in den Fig. 2,3 und 5 veranschaulicht ist:

  • In dem Gehäuse 2 bzw. der Bandtrommel 4 ist eine quer zu dem Band 3 verlaufende zylindrische Bohrung 6 vorgesehen, die bei der Bandtrommel 4 parallel zu deren Drehachse ausgerichtet ist.
The ends of the band 3 are connected to the housing 2 and the band drum 4 with a fastening device 5, the structure of which is illustrated in several embodiments, in particular in FIGS. 2, 3 and 5:
  • Provided in the housing 2 or the tape drum 4 is a cylindrical bore 6 extending transversely to the tape 3, which is aligned parallel to the axis of rotation of the tape drum 4.

In die als Sackbohrung ausgebildete Bohrung 6 führt ein Einführschlitz 7, der - wie insbesondere aus Fig. 4 zu ersehen - von abgerundeten Einführflächen 8 begrenzt ist. In der Bohrung 6 ist ein außen zylindrisches Klemmelement 9 (Fig. 2) oder 9a (Fig. 3,5) eingefügt, das mittels eines Spannelementes 10 in Gestalt einer Spannhülse in seinem Außendurchmesser veränderbar ist.An insertion slot 7, which - as can be seen in particular from FIG. 4 - is delimited by rounded insertion surfaces 8 leads into the bore 6 designed as a blind bore. An externally cylindrical clamping element 9 (FIG. 2) or 9a (FIG. 3.5) is inserted in the bore 6 and its outer diameter can be changed by means of a clamping element 10 in the form of a clamping sleeve.

Das Ende des Bandes 3 ist jeweils durch den Einführschlitz 7 in die Bohrung 6 eingeführt, sodann um das zylindrische Klemmelement 9 bzw. 9a herumgeführt (vergl. Fig. 1,4,5) und zwischen der Wand der Bohrung 6 und der Außenumfangsfläche des mittels der Spannhülse 10 aufgeweiteten Klemmelementes 9 bzw. 9a reibschlüssig verklemmt.The end of the band 3 is inserted through the insertion slot 7 into the bore 6, then around the cylindrical clamping element 9 or 9a (see. Fig. 1,4,5) and between the wall of the bore 6 and the outer peripheral surface of the means the clamping sleeve 10 expanded clamping element 9 or 9 a frictionally jammed.

Bei der Ausführungsform nach Fig. 2 ist das Klemmelement 9 in Gestalt einer längsgeschlitzten Klemmbüchse aus Metall- oder Kunststoffmaterial ausgebildet, die auf ihrer Innenseite zwei gegenläufige konische Spannflächen 11 trägt, die ihrerseits auf entsprechenden Konusflächen des zweiteiligen Spannelementes 10 abgestützt sind.In the embodiment according to FIG. 2, the clamping element 9 is designed in the form of a longitudinally slotted clamping sleeve made of metal or plastic material, which carries on its inside two opposing conical clamping surfaces 11, which in turn are supported on corresponding conical surfaces of the two-part clamping element 10.

Wird eine in ein Gewindeloch 13 im Boden.der Bohrung 6 eingeschraubte Spannschraube 100 festgezogen, so werden die beiden Teile des Spannelementes 10 - von denen eines ein Gewinde trägt - axial aufeinander zubewegt, mit dem Ergebnis, daß über die konischen Spannflächen 11 und die Konusflächen 12 das Klemmelement 9 in Gestalt der Klemmbüchse aufgeweitet und das Ende des Bandes 3 in der bereits beschriebenen Weise mit der Wand der Bohrung 6 verklemmt werden.If a clamping screw 100 screwed into a threaded hole 13 in the bottom 6 of the bore 6 is tightened, the two parts of the clamping element 10 - one of which carries a thread - are axially moved towards one another with the The result is that the clamping element 9 is expanded in the form of the clamping sleeve via the conical clamping surfaces 11 and the conical surfaces 12 and the end of the band 3 is clamped to the wall of the bore 6 in the manner already described.

Bei der Ausführungsform nach Fig. 3 besteht das Klemmelement 9a aus einem hülsenartigen Federelement aus elastischem Material, durch dessen Bohrung die in das Gewindeloch 13 eingeschraubte Spannschraube 100 verläuft. Die Spannschraube 100 stützt sich über einen Federteller 14 gegen das Klemmelement 9a ab. Wird sie festgezogen, so wird das elastische Material des Klemmelementes 9a axial zusammengepreßt, womit das Klemmelement eine entsprechende radiale Aufweitung erfährt, die in bereits erläuterter Weise die Verklemmung des Endes des Bandes 3 mit der Wandung der Bohrung 6 bewirkt.In the embodiment according to FIG. 3, the clamping element 9a consists of a sleeve-like spring element made of elastic material, through the bore of which the clamping screw 100 screwed into the threaded hole 13 runs. The clamping screw 100 is supported via a spring plate 14 against the clamping element 9a. If it is tightened, the elastic material of the clamping element 9a is axially compressed, so that the clamping element experiences a corresponding radial expansion, which causes the end of the band 3 to be clamped to the wall of the bore 6 in the manner already explained.

Bei der Ausführungsform nach Fig. 5 ist in die Bohrung 6 ein hülsenartiges Einlegeteil 15 eingesetzt, das beispielsweise aus Kunststoffmaterial besteht und bei 16 auch den Einführungsschlitz 7 vollständig auskleidet, wobei bei 8 wiederum die abgerundeten Einführungsflächen für das Band 3 vorhanden sind. In das Einlegeteil 15 ist das Klemmelement 9a nach Fig. 3 eingesetzt, durch das beim Festziehen der Spannschraube 100 das Ende des Bandes 3 in bereits beschriebener Weise mit der Innenwand des Einlegeteils 15 verklemmt wird.In the embodiment according to FIG. 5, a sleeve-like insert 15 is inserted into the bore 6, which consists, for example, of plastic material and also completely lines the insertion slot 7 at 16, the rounded insertion surfaces for the band 3 also being present at 8. The clamping element 9a according to FIG. 3 is inserted into the insert 15 , by which the end of the band 3 is clamped to the inner wall of the insert 15 in the manner already described when the clamping screw 100 is tightened.

Die Innenwand des Einlegeteiles 15 weist eine bei 17 angedeutete Profilierung auf, durch die die erzielbare maximale Haltekraft der Befestigungsvorrichtung 5 erhöht wird. Es wäre auch denkbar, bei den Ausführungsformen nach Fig. 2,3 eine solche Profilierung unmittelbar auf der Wand der Bohrung 6 vorzusehen, worauf der Ordnung halber hingewiesen sei.The inner wall of the insert part 15 has a profile indicated at 17, by means of which the achievable maximum holding force of the fastening device 5 is increased. It would also be conceivable to provide such a profiling directly on the wall of the bore 6 in the embodiments according to FIG. 2, which is pointed out for the sake of order.

Während bei den dargestellten Ausführungsformen die Spannschraube 100 jeweils in das im Boden der Sackbohrung 6 vorgesehene Gewindeloch 13 eingeschraubt ist, wäre es auch denkbar, die Anordnung derart zu treffen, daß die Bohrung 6 als Durchgangsbohrung ausgebildet ist und die Spannschraube 100 eine Gewindemutter trägt, die auf der dem Schraubenkopf abgewandten Seite gegen das Klemmelement 9 bzw. 9a abgestützt ist.While in the illustrated embodiments, the clamping screw 100 is screwed into the threaded hole 13 provided in the bottom of the blind hole 6, it would also be conceivable to make the arrangement such that the hole 6 is designed as a through-hole and the clamping screw 100 carries a threaded nut which is supported on the side facing away from the screw head against the clamping element 9 or 9a.
