Abstract

Eine Rundschlinge zum Heben von Lasten besteht aus einem zu einem Fadengelege gelegten Endlosstrang (1) als tragender Kern und aus einem den Endlosstrang (1) umgebenden textilen Schutzschlauch. Erfindungsgemäß führt der Endlosstrang (1) einen Prüfleiter (4) mit sich, der mit zwei die Wand des Schutzschlauches (2) durchsetzenden Anschlußkontakten für das Prüfmedium verbunden ist.A round sling for lifting loads consists of an endless strand (1) laid as a load-bearing core and a textile protective hose surrounding the endless strand (1). According to the invention, the endless strand (1) carries with it a test conductor (4) which is connected to two connecting contacts for the test medium which pass through the wall of the protective tube (2).

Description

Die Erfindung betrifft eine Rundschlinge zum Heben von Lasten mit den im Oberbegriff des Anspruches 1 aufgeführten Merkmalen. Der konstruktive Aufbau solcher auch als gewebte Hebebänder bezeichneter Rundschlingen ist Gegenstand von DIN 61 360. Der Faden des Endlosstranges besteht aus einem synthetischen, multifilen Werkstoff.The invention relates to a round sling for lifting loads with the features listed in the preamble of claim 1. The construction of such round slings, also known as woven lifting slings, is the subject of DIN 61 360. The thread of the endless strand consists of a synthetic, multifilament material.

Derartige Rundschlingen müssen in bestimmten Zeit­abständen immer wieder auf Unversehrtheit überprüft werden. Diese Überprüfung beschränkt sich notgedrungen weitgehend auf die Prüfung der Unversehrtheit des Schutzschlauches, weil das Fadengelege bzw. der Endlosstrang wegen der Umhüllung durch den aus nicht­durchsichtigem Textilwerkstoff bestehenden Schutz­schlauch durch Augenschein nicht überprüfbar ist, obwohl der Endlosstrang allein den tragenden Kern der Rundschlinge bildet.Such round slings have to be checked for integrity at certain intervals. This check is inevitably largely limited to checking the integrity of the protective hose, because the scrim or the endless strand cannot be checked visually due to the covering by the protective tube made of non-transparent textile material, although the endless strand alone forms the load-bearing core of the round sling.

Der Erfindung liegt die Aufgabe zugrunde, eine Rund­schlinge der eingangs genannten Art zu schaffen, die ohne besondere Sachkundigkeit eine Überprüfung der Unversehrtheit ihres Endlosstranges ermöglicht. Diese Aufgabe wird durch den kennzeichnenden Teil des Anspruches 1 gelöst.The invention has for its object to provide a round sling of the type mentioned, which allows a check of the integrity of its endless strand without special expertise. This object is solved by the characterizing part of claim 1.

Die Erfindung geht aus von der Erkenntnis, daß die Tragfähigkeit einer Rundschlinge dann beeinträchtigt ist, wenn eine der vielen Windungen des Fadengeleges bzw. des tragenden Endlosstranges beschädigt oder insbesondere durchtrennt ist. Eine solche Beschädigung oder Durchtrennung des Endlosstranges hat einen von außen meßbaren Einfluß auf den Durchgang des an die Enden des Prüfleiters angelegten Prüfmediums. Die Werkstoffeigenschaften des Prüfleiters sollen so beschaffen sein, daß bei einer Überlastung in Längsrichtung erst der Endlosstrang und dann der Prüfleiter reißt.The invention is based on the finding that the load-bearing capacity of a round sling is impaired when one of the many turns of the scrim or the supporting endless strand is damaged or is particularly severed. Such damage or severing of the endless strand has an externally measurable influence on the passage of the test medium applied to the ends of the test conductor. The material properties of the test conductor should be such that, in the event of an overload in the longitudinal direction, only the endless strand and then the test conductor breaks.

Besonders einfach läßt sich die Verbindung des Prüf­leiters an seinen beiden Enden mit dem Schutzschlauch herstellen. Durch das Kennzeichnungsmerkmal des Anspruches 4 ist sichergestellt, daß der Endlosstrang über seine gesamte Länge der Überprüfung seiner Unversehrtheit durch den Prüfleiter unterzogen werden kann. Dies läßt sich in einfacher Weise dadurch gewährleisten, daß der Prüfleiter gemeinsam mit dem Faden des Endlosstranges gesponnen wird. Dabei kann der Prüfleiter rundum in den Faden des Endlos­stranges eingebettet sein, wodurch in vorteilhafter Weise sichergestellt wird, daß er nicht in unmittelbaren Kontakt mit dem Prüfleiter einer benachbarten Windung des Endlosstranges kommt.The test conductor can be connected to the protective tube at both ends in a particularly simple manner. The identification feature of claim 4 ensures that the continuous strand can be checked over its entire length for its integrity by the test manager. This can be ensured in a simple manner in that the test conductor is spun together with the thread of the endless strand. The test conductor can be embedded all around in the thread of the endless strand, which advantageously ensures that it does not come into direct contact with the test conductor of an adjacent turn of the endless strand.

Die höhere Dehnfähigkeit des Prüfleiters im Verhältnis zur Dehnfähigkeit des Fadens des Endlosstranges läßt sich z.B. dadurch erreichen, daß der Endlosleiter wellen- oder wendelförmig in Längsrichtung des Fadens des Endlosstranges verläuft.The higher elasticity of the test conductor in relation to the elasticity of the thread of the endless strand can be e.g. thereby achieve that the endless conductor runs in an undulating or helical shape in the longitudinal direction of the thread of the endless strand.

Der Prüfleiter kann ein elektrischer Leiter für eine Stromdurchgangsprüfung sein. Hierzu kann er vorteilhaft von einer Isolierung ummantelt sein. Es ist jedoch in gleicher Weise möglich, daß der Prüfleiter ein Lichtleiter für eine Lichtdurchgangs­prüfung ist.The test conductor can be an electrical conductor for a continuity test. For this purpose, it can advantageously be encased in insulation. However, it is equally possible for the test conductor to be a light guide for a light continuity test.

Die Erfindung wird anhand eines in den Figuren dar­gestellten Ausführungsbeispiels näher erläutert. Es zeigen:

  • Fig. 1 die Gesamtansicht einer Rundschlinge der erfindungsgemäßen Art,
  • Fig. 2 den vergrößerten Teilausschnitt II in Fig. 1,
  • Fig. 3 einen Schnitt entsprechend der Linie III-III in Fig. 1 und 2.
The invention is explained in more detail with reference to an embodiment shown in the figures. Show it:
  • 1 is the overall view of a round sling of the type according to the invention,
  • 2 shows the enlarged partial section II in FIG. 1,
  • 3 shows a section along the line III-III in FIGS. 1 and 2.

Der tragende Kern der Rundschlinge besteht aus einem zu einem Fadengelege gelegten Endlosstrang 1 aus synthetischem, multifilem Fadenwerkstoff, z.B. aus einem Polyamid- und/oder Polyesterfaserfaden. Die Anzahl der einzelnen Windungen 11 von neben­einanderliegenden Strangabschnitten bestimmt die vom Fadengelege aufzunehmende Traglast der Rundschlinge. Das Fadengelege bzw. der Endlosstrang 1 ist von einem ihn lose umgebenden Schutzschlauch 2 umhüllt. Der Schutzschlauch 2 besteht aus einem textilen Schlauchgewebe oder aus einem vernähten Textilgewebe. Der Schutzschlauch ist nur zu etwa 60% bis 70% seiner maximalen Schlauchquerschnittsfläche vom Fadengelege bzw. vom Endlosstrang 1 gefüllt. Der Schutzschlauch 2 liegt darüber hinaus in Umfangsrichtung 3 der Rundschlinge leicht in Falten, damit eine im Belastungs­fall eintretende Dehnung und damit Vergrößerung der Umfangslänge des Fadengeleges bzw. des Endlos­stranges 1 immer noch nicht zur Einwirkung einer Zugbelastung auf den Schutzschlauch und damit zu einer Beschädigungsgefahr für diesen führt. Durch die Lose, mit der das Fadengelege bzw. der Endlosstrang 1 im Schutzschlauch 2 einliegt, ist sichergestellt, daß sich der Schutzschlauch 2 gegenüber dem Fadengelege bzw. Endlosstrang 1 und die einzelnen Fadenstränge bzw. Windungen 11 zum selbsttätigen Lastausgleich leicht gegeneinander verschieben können.The load-bearing core of the round sling consists of an endless strand 1 made of synthetic, multifilament thread material, for example of a polyamide and / or polyester fiber thread. The number of individual turns 11 of adjacent strand sections determines the load capacity of the round sling to be taken up by the laid scrim. The scrim or the endless strand 1 is encased by a protective tube 2 loosely surrounding it. The protective hose 2 consists of a textile hose fabric or a sewn textile fabric. The protective hose is only filled to about 60% to 70% of its maximum hose cross-sectional area by the scrim or the endless strand 1. The protective tube 2 is also slightly in the circumferential direction 3 of the round sling in folds, so that an expansion occurring in the event of a load and thus an increase in the circumferential length of the scrim or the endless strand 1 are still not to act on a tensile load on the protective tube and thus to damage it leads. The slack with which the scrim or the endless strand 1 lies in the protective tube 2 ensures that the protective tube 2 is opposite the scrim or endless strand 1 and the individual thread strands or windings 11 can easily shift against each other for automatic load balancing.

Der Endlosstrang 1 weist in seiner Mitte einen mit­geführten Prüfleiter 4 auf, dessen beide Enden 41,42 mit zwei Anschlußenden bzw. Anschlußkontakten 5,6 für das Prüfmedium verbunden sind, wobei die Anschluß­kontakte 5,6 die Wand des Schutzschlauches 2 durch­setzen, so daß sie von außen zugänglich sind. Sofern die Rundschlinge mehrere Endlosstränge 1 als Fadengelege aufweist, ist jedem Endlosstrang 1 ein Prüfleiter 4 mit zwei entsprechend aus dem Schutzschlauch 2 herausgeführten Anschlußenden bzw. -kontakten 5,6 zugeordnet. Zweckmäßig weist der Prüfleiter 4 dieselbe Länge wie der ihm zugeordnete Endlosstrang 1 auf, so daß er über dessen gesamte Länge mitgeführt ist.The endless strand 1 has in its center a carried test conductor 4, the two ends 41, 42 of which are connected to two connecting ends or connecting contacts 5, 6 for the test medium, the connecting contacts 5, 6 passing through the wall of the protective tube 2, so that they are accessible from the outside. If the round sling has a plurality of endless strands 1 as a scrim, each test strand 4 is assigned to each endless strand 1 with two connecting ends or contacts 5, 6 respectively led out of the protective tube 2. The test conductor 4 expediently has the same length as the continuous strand 1 assigned to it, so that it is carried over its entire length.

Der Prüfleiter 4 kann ein elektrischer Leiter für eine Stromdurchgangsprüfung sein. In einem solchen Falle ist der elektrische Leiter zweckmäßig mit einer Isolierung 12 ummantelt, um eine gegenseitige Kontaktierung der Prüfleiter von benachbart aneinander­liegenden Fäden bzw. Windungen 11 des Endlosstranges 1 zu vermeiden. Der Prüfleiter 4 kann jedoch auch ein Lichtleiter für eine Lichtdurchgangsprüfung sein.The test conductor 4 can be an electrical conductor for a continuity test. In such a case, the electrical conductor is expediently sheathed with an insulation 12 in order to avoid mutual contacting of the test conductors by threads or turns 11 of the endless strand 1 lying adjacent to one another. However, the test conductor 4 can also be a light guide for a light continuity test.

Solange der Prüfleiter 4 unbeschädigt ist, läßt sich leicht auch von einem nicht sachverständigen Benutzer mittels eines einfachen Durchgangsprüfgerätes feststellen, ob der Prüfleiter noch intakt oder aber durchtrennt ist. Ist keine Windung 11 des Endlosstranges 1 durchtrennt, so zeigt das Durch­ gangsprüfgerät Durchgang an. Liegt hingegen eine Durchtrennung vor, so wird dies vom Durchgangsprüfgerät angezeigt. Beispielsweise kommt bei einem elektrischen Prüfleiter ein Stromfluß nicht zustande. Ist der Prüfleiter ein Lichtleiter, so läßt sich selbst eine nur teilweise Durchtrennung desselben optisch in einfacher Weise feststellen. Jedenfalls ermöglicht die erfindungsgemäße Ausbildung der Rundschlinge eine einfache Überprüfung, ob der tragende Kern der Rundschlinge noch intakt ist.As long as the test manager 4 is undamaged, it can easily be determined even by an inexperienced user by means of a simple continuity tester whether the test manager is still intact or severed. If no turn 11 of the endless strand 1 is cut, the through shows gait tester continuity on. However, if there is a cut, this is indicated by the continuity tester. For example, a current does not flow with an electrical test conductor. If the test conductor is a light guide, even a partial separation of the same can be determined optically in a simple manner. In any case, the design of the round sling according to the invention enables simple checking whether the load-bearing core of the round sling is still intact.
