Definitions
- the invention relates to a round sling or endless sling of the type previously described in the preamble of claim 1 and known from DE-B No. 2129837.
- the core only fills the cross-section of the protective tube to about 50-70% and is therefore freely longitudinally movable in relation to the protective tube and that the individual windings of the core are also not fixed in relation to the protective tube and to one another. It is only in this way that it is possible for the different windings to move in relation to one another under a load attack and to have the same length as a result of the load, so that overloading of a single thread winding is avoided.
- a feature of such a round sling also consists in the fact that in the unloaded state the protective tube is somewhat longer than the core, so that the protective tube lies in slight folds along the core.
- the prefabricated protective tube is placed on a tube that is open on one side in the longitudinal direction over a circumferential area of approximately 180 °, i.e. pushed onto a gutter and pushed or compressed in the longitudinal direction to less than half of its length so that the tube surrounds the tube with a strong fold.
- a thread of textile yarn, plastic or the like is drawn in the longitudinal direction through the tube interior or through the interior of the protective tube.
- the end of the thread drawn through is then drawn back on the outside of the protective tube back to the insertion end and again drawn through the protective tube or the groove in the longitudinal direction. This process is repeated many times in such a way that a thread roll consisting of many layers of thread circles, but formed from only one thread, is created.
- the protective tube is pushed from the groove in the longitudinal direction onto the thread winding or threads.
- the thread wrap is then removed from the trough so that it is also free.
- the compressed protective tube is then pushed over the entire circumference of the thread winding. Its ends are inserted into each other and preferably sewn together.
- the protective tube has an initial length such that, in the final state, it is still somewhat longer than the thread wrap or the threads around it. As a result, he surrounds the thread winding (s) with a light drapery.
- the invention is based on the object of designing a round sling of the type mentioned at the outset in such a way that the very flat cross-sectional shape which arises under load, in particular in the system areas, is as far as possible predetermined by the construction of the round sling, or that such a flat cross-sectional shape is also taken even before a load attack, in particular under load, if possible, is already stimulated by design.
- This object is achieved by the characterizing part of claim 1 and is given an additional support effect by the characterizing part of claim 2.
- the flat webs could theoretically also be formed by sewing two strips lying one on top of the other in the edge regions to form a tube.
- the flat webs can advantageously be easily incorporated when the protective tube is being woven.
- a tube is a two-layer weave, the two layers of which are not connected to one another.
- known two-ply webbing straps are produced, which differ from woven hoses only in that their two ply layers are connected to one another by a binding chain incorporated during weaving.
- Such two-ply webbing straps can also be used according to the invention.
- said flat web or flats are formed by incorporating or running in a binding chain in the desired flat web regions when weaving the protective tube. The chain-free areas of the two-layer fabric then form the actual hose.
- the flat webs also have the effect of a wear protection strip on both sides.
- the further invention relates to a sling formed from such a round sling.
- Stropp is used to denote round slings in which two round sling parts lying opposite one another are combined or connected to one another in an intermediate region between two hanging eyes.
- the further invention now consists in the mutual connection of the two round sling parts by sewing their opposing flat webs to one another. This ensures that the sewing needle used to produce the connecting seam does not pierce the thread winding and can damage its individual threads. This also ensures that the free movement of the individual threads relative to the protective tube and relative to one another, which is so important for the functionality of the round sling or the sling, is not impaired by the seam.
- the inventive design of the sling enables the application of an abrasion protection pad - also called a work surface - also without damaging the load-bearing thread winding or without impairing the round loop or thread winding function according to the characterizing part of claim 5.
- the invention makes it possible, in accordance with the characterizing part of claim 6, to securely fasten protective tubes for the hanging eyes of the slings in a simple manner.
- the round sling designated overall by 1, consists of a core 2 in the form of one or more thread windings and a seamlessly woven protective tube 3 surrounding the core 2 in its entirety with considerable slack. At least one flat web 4 protruding laterally from its cross section is attached to the protective tube 3 woven.
- the thread winding of the core 2 consists of monofilament plastic threads drawn endlessly into the tube 3.
- the flat web 4 is formed during the tube weaving process simply by incorporating a binding chain over its width 5 into the two-layer fabric, as is familiar to every weaving specialist.
- the round sling 1 shown in FIG. 2 has an woven flat web 4 or 6 on two diagonally opposite sides of the hose cross section.
- the abutting flat webs 4 of two adjacent parts of the protective tube 3 are sewn to one another by the seam 7.
- the strop 12 is formed in that in the intermediate area 8 between the hanging eyes 9 two round sling parts 10, 11 are grouped together.
- an abrasion protection pad 13 in the form of e.g. a textile band can be sewn or fastened by sewing (seams 7, 14) with at least one of the flat webs 4, 6.
- FIG. 5 shows a round loop mat 18 produced using three round slings 3 or 12, with the hanging eyes 9 suspended in a lifting harness 17.
- the round slings 3 are placed next to one another in the manner of strops 12. They are connected to one another by seams 7 and 14, which in turn are introduced into the flat webs 4 and 6, respectively.

Description
Die Erfindung betrifft eine Rundschlinge bzw. endlose Schlinge der im Oberbegriff des Anspruches 1 näher gekennzeichneten, aus DE-B Nr. 2129837 vorbekannten Art.The invention relates to a round sling or endless sling of the type previously described in the preamble of
Wesentlich für derartige Rundschlingen ist es, dass der Kern den Querschnitt des Schutzschlauches nur zu etwa 50-70% ausfüllt und somit im Verhältnis zum Schutzschlauch frei längsbeweglich und dass die einzelnen Wicklungen des Kerns im Verhältnis zum Schutzschlauch und zueinander ebenfalls nicht fixiert sind. Nur dadurch ist es nämlich möglich, dass die verschiedenen Wicklungen sich unter Lastangriff im Verhältnis zueinander bewegen und infolge der Belastung die gleiche Länge erhalten, so dass eine Überbelastung einer einzelnen Fadenwicklung vermieden wird.It is essential for round slings of this type that the core only fills the cross-section of the protective tube to about 50-70% and is therefore freely longitudinally movable in relation to the protective tube and that the individual windings of the core are also not fixed in relation to the protective tube and to one another. It is only in this way that it is possible for the different windings to move in relation to one another under a load attack and to have the same length as a result of the load, so that overloading of a single thread winding is avoided.
Ein Merkmal einer solchen Rundschlinge besteht auch darin, dass in unbelastetem Zustand der Schutzschlauch etwas länger ist als der Kern, so dass der Schutzschlauch längs des Kerns in leichten Falten liegt.A feature of such a round sling also consists in the fact that in the unloaded state the protective tube is somewhat longer than the core, so that the protective tube lies in slight folds along the core.
Das Herstellungsverfahren einer solchen Rundschlinge ist ebenfalls in DE-B Nr. 2129837 näher beschrieben.The manufacturing process of such a round sling is also described in more detail in DE-B No. 2129837.
Hierzu wird der vorgefertigte schutzschlauch auf ein einseitig in Längsrichtung über einen Umfangsbereich von etwa 180° durchgehend offenes Rohr, d.h. auf eine Rinne aufgeschoben und dabei so in Längsrichtung auf weniger als die Hälfte ihrer Länge zusammengeschoben bzw. gestaucht, dass der Schlauch unter starkem Faltenwurf das Rohr umgibt. Sodann wird ein Faden aus Textilgarn, Kunststoff o. dgl. in Längsrichtung durch den Rohrinnenraum bzw. durch den Innenraum des Schutzschlauches hindurchgezogen. Das hindurchgezogene Ende des Fadens wird dann auf der Aussenseite des Schutzschlauches wieder zu dem Einführungsende zurück und erneut durch den Schutzschlauch bzw. die Rinne in Längsrichtung hindurchgezogen. Dieser Vorgang wiederholt sich vielfach derart, dass ein aus vielen Fadenkreislagen bestehender, jedoch nur aus einem Faden gebildeter Fadenwickel entsteht. Infolge der grossen Anzahl von nebeneinanderliegend dem Schutzschlauch durchsetzenden Lagen des Fadens ist es nicht notwendig, die Enden des Fadens miteinander zu verknoten oder zu verbinden. Die Enden können vielmehr lose sein, ohne dass dadurch die Zugfestigkeit des Fadenwickels beeinträchtigt wird. Nach der derartigen Herstellung des Fadenwickels wird der Schutzschlauch von der Rinne in Längsrichtung auf den bzw. die Fadenwickel abgeschoben. Der Fadenwickel wird sodann aus der Rinne herausgenommen, so dass auch er frei ist. Sodann wird der gestauchte Schutzschlauch über den gesamten Umfang des Fadenwickels hinübergeschoben. Seine Enden werden ineinandergesteckt und vorzugsweise miteinander vernäht. Der Schutzschlauch weist eine solche Ausgangslänge auf, dass er im Endzustand immer noch etwas länger ist als der bzw. die von ihm umgebenen Fadenwickel. Dadurch umgibt er mit leichtem Faltenwurf den bzw. die Fadenwikkel.For this purpose, the prefabricated protective tube is placed on a tube that is open on one side in the longitudinal direction over a circumferential area of approximately 180 °, i.e. pushed onto a gutter and pushed or compressed in the longitudinal direction to less than half of its length so that the tube surrounds the tube with a strong fold. Then a thread of textile yarn, plastic or the like is drawn in the longitudinal direction through the tube interior or through the interior of the protective tube. The end of the thread drawn through is then drawn back on the outside of the protective tube back to the insertion end and again drawn through the protective tube or the groove in the longitudinal direction. This process is repeated many times in such a way that a thread roll consisting of many layers of thread circles, but formed from only one thread, is created. Due to the large number of layers of thread passing through the protective tube side by side, it is not necessary to knot or connect the ends of the thread. Rather, the ends can be loose without the tensile strength of the thread winding being impaired thereby. After the thread winding has been produced in this way, the protective tube is pushed from the groove in the longitudinal direction onto the thread winding or threads. The thread wrap is then removed from the trough so that it is also free. The compressed protective tube is then pushed over the entire circumference of the thread winding. Its ends are inserted into each other and preferably sewn together. The protective tube has an initial length such that, in the final state, it is still somewhat longer than the thread wrap or the threads around it. As a result, he surrounds the thread winding (s) with a light drapery.
Ein wesentliches Merkmal derartiger bekannter Rundschlingen besteht darin, dass sie in den Anlagebereichen am Kran haken oder an der Last eine sehr flach-ovale Querschnittsform einnehmen, bei der die Einzelfäden des bzw. der Fadenwickel weitgehend nebeneinander- und nicht aufeinanderliegen. Gerade dieser Umstand sorgt für eine gleichmässige Lastverteilung auf die einzelnen Wicklungen des Fadenwickels.An essential feature of such known round slings is that they hook in the system areas on the crane or take on a very flat oval cross-sectional shape in which the individual threads of the thread winding (s) lie largely side by side and not on top of each other. It is precisely this fact that ensures an even load distribution on the individual windings of the thread winding.
Der Erfindung liegt die Aufgabe zugrunde, eine Rundschlinge der eingangs genannten Art so auszubilden, dass die sehr flache, unter Lastangriff insbesondere in den Anlagebereichen sich einstellende Querschnittsform möglichst weitgehend bereits durch die Konstruktion der Rundschlinge vorgegeben ist, bzw. dass die Einnahme einer solchen Flachquerschnittsform auch schon vor einem Lastangriff, insbesondere aber unter Last möglichst bereits durch konstruktive Vorgabe stimuliert wird. Diese Aufgabe wird durch das Kennzeichen des Anspruchs 1 gelöst und erfährt durch das Kennzeichen des Anspruchs 2 noch eine zusätzliche Unterstützungswirkung. Bei der Lösung gemäss Anspruch 2 könnten die Flachstege auch theoretisch durch gegenseitiges Vernähen zweier aufeinanderliegender Bänder in deren Randbereichen zu einem Schlauch gebildet sein. Die Flachstege lassen sich jedoch vorteilhaft leicht bereits bei der Webeherstellung des Schutzschlauches mit einarbeiten. Hierbei ist zu berücksichtigen, dass webtechnisch ein Schlauch ein Zweilagengewebe ist, dessen beide Lagen nicht miteinander verbunden sind. In ähnlicher Weise werden bekannte Zweilagen-Gurtbänder hergestellt, die sich von gewebten Schläuchen nur dadurch unterscheiden, dass ihre beiden Gewebelagen durch eine beim Weben eingearbeitete Bindekette miteinander verbunden sind. Auch solche Zweilagen-Gurtbänder lassen sich nach der Erfindung verwenden. Erfindungsgemäss wird der genannte Flachsteg bzw. werden die genannten Flachstege dadurch gebildet, dass man beim Weben des Schutzschläuches in den gewünschten Flachstegbereichen eine Bindekette einarbeitet bzw. einlaufen lässt. Die bindekettenfreien Bereiche des Zweilagengewebes bilden dann den eigentlichen Schlauch.The invention is based on the object of designing a round sling of the type mentioned at the outset in such a way that the very flat cross-sectional shape which arises under load, in particular in the system areas, is as far as possible predetermined by the construction of the round sling, or that such a flat cross-sectional shape is also taken even before a load attack, in particular under load, if possible, is already stimulated by design. This object is achieved by the characterizing part of
Die Flachstege haben auch die Wirkung einer, beidseitigen Verschleissschutzleiste.The flat webs also have the effect of a wear protection strip on both sides.
Die weitere Erfindung betrifft einen aus einer derartigen Rundschlinge gebildeten Stropp. Mit Stropp bezeichnet man solche Rundschlingen, bei denen zwei einander gegenüberliegende Rundschlingenteile in einem Zwischenbereich zwischen zwei Einhängeaugen aneinanderliegend zusammengefasst bzw. miteinander verbunden sind. Die weitere Erfindung besteht nun darin, dass die gegenseitige Verbindung der beiden Rundschlingenteile durch Vernähung ihrer einander ge- ' genüberliegenden Flachstege miteinander erfolgt. Damit ist sichergestellt, dass die zur Herstellung der Verbindungsnaht verwendete Nähnadel nicht in den Fadenwickel einstechen und deren einzelnen Fäden beschädigen kann. Weiterhin ist dadurch sichergestellt, dass durch die Naht die freie, für die Funktionsfähigkeit der Rundschlinge bzw. des Stropps so wichtige Beweglichkeit der einzelnen Fäden gegenüber dem Schutzschlauch und relativ zueinander nicht beeinträchtigt ist.The further invention relates to a sling formed from such a round sling. Stropp is used to denote round slings in which two round sling parts lying opposite one another are combined or connected to one another in an intermediate region between two hanging eyes. The further invention now consists in the mutual connection of the two round sling parts by sewing their opposing flat webs to one another. This ensures that the sewing needle used to produce the connecting seam does not pierce the thread winding and can damage its individual threads. This also ensures that the free movement of the individual threads relative to the protective tube and relative to one another, which is so important for the functionality of the round sling or the sling, is not impaired by the seam.
Die erfindungsgemässe Ausbildung des Stropps ermöglicht die Aufbringung einer Abriebschutzauflage - auch Arbeitsfläche genannt - ebenfalls ohne Beschädigung des tragenden Fadenwickels bzw. ohne Beeinträchtigung der Rundschlingen- bzw. Fadenwickelfunktion nach dem Kennzeichen des Anspruchs 5.The inventive design of the sling enables the application of an abrasion protection pad - also called a work surface - also without damaging the load-bearing thread winding or without impairing the round loop or thread winding function according to the characterizing part of
Weiterhin ist es durch die Erfindung möglich, gemäss dem Kennzeichen des Anspruchs 6 in einfacher Weise Schutzschläuche für die Einhängeaugen des Stroppsverschiebesicher zu befestigen.Furthermore, the invention makes it possible, in accordance with the characterizing part of
Nach dem Kennzeichen des Anspruchs 7 ist es in einfacher Weise möglich, durch mehrere nebeneinander gelegte und erfindungsgemäss miteinander verbundene Rundschlingen oder Stropps eine Rundschlingenmatte ähnlich solcher herzustellen, wie diese z.B. zum Verlegen von Rohrleitungen verwendet wird.According to the characterizing part of claim 7, it is possible in a simple manner to produce a round sling mat similar to such as those e.g. is used to lay pipes.
