Abstract

Each of the two rims (1) of the reel are connected to a hub flange (3) by means of welded-on spokes (2). All the spokes (2) are screwed with drum segments (7). Side wall segments (29) consisting of glass-fibre-reinforced plastic are attached to the spokes (2), between the drum segments (7) and the rim (1). The drum segments (7) are covered with a plastic sheet (36). This design makes it possible for the reel to be dismantled, with the result that transport and storage volume as well as repair costs are small. The winding material is well protected. The reel can be lightly built by virtue of the favourable transmission of force. <IMAGE>

Description

Energiekabel werden im Herstellerwerk auf Spulen aufgewickelt und schliesslich auf Spulen versandt. Herkömmliche Spulen dieser Art sind verschweisste Stahlkonstruktionen mit zwei Radreifen, die zum Beispiel über Speichen mit inneren Ringen verbunden sind. Die inneren Ringe ihrerseits tragen eine Trommel, auf welche das Kabel aufgewickelt wird, und sind über zwei oder drei Zentralspeichen mit je einem Nabelflansch verbunden. Die Nabenflansche haben eine zentrale Bohrung, mit welcher sie auf einer Welle oder auf konischen Zapfen gelagert werden. Um die axialen Kräfte im letztgenannten Fall aufzunehmen, sind bei den bekannten Spulen die Nabenflansche in den Zentralspeichenebenen diagonal mit den inneren Ringen verstrebt.Energy cables are wound on spools in the manufacturing plant and then shipped on spools. Conventional coils of this type are welded steel structures with two wheel tires, which are connected to inner rings, for example, by spokes. The inner rings in turn carry a drum on which the cable is wound and are connected to two umbilical flanges via two or three central spokes. The hub flanges have a central hole with which they are mounted on a shaft or on conical pins. To absorb the axial forces in the latter case, the hub flanges in the central spoke planes are braced diagonally with the inner rings in the known coils.

Diese bekannten Spulen werden üblicherweise verzinkt. Sie sind robust und haben sich bewährt. Allerdings haben sie bei der Erstlieferung vom Herstellerwerk zum Spulenhersteller ein grosses Transportvolumen, was den Transport verteuert. Auch sind sie statisch nicht optimal dimensioniert.These known coils are usually galvanized. They are robust and have proven themselves. However, when they are delivered for the first time from the manufacturer to the reel manufacturer, they have a large transport volume Transport more expensive. They are also not optimally dimensioned statically.

Energiekabel haben in neuerer Zeit oft eine Abschirmung, um die Verluste zu vermindern. Die auf die Abschirmung in der letzten Operation der Kabelherstellung aufgebrachte Isolation braucht nur dünn zu sein. Solch dünne Isolationsschichten werden jedoch bei den bekannten Spulen häufig durch den Schlupf beschädigt, den das Kabel bei der Abkühlung von der Herstelltemperatur auf Raumtemperatur unvermeidlich auf der Trommel erleidet. Auch bei sorgfältiger Herstellung sind nämlich die Trommeln und die Seitenwände selten ideal glatt, weil kleine Schweissperlen kaum zu sehen sind und sich beim Verzinken, das heisst beim Herausziehen aus dem Zinkbad, unvermeidlich Schlackenteile von der Oberfläche des Zinkbades ablagern. Ausserdem ist der Zinkschicht die abschliessende Wärmebehandlung des Kabels zum Vernetzen der äusseren Isolationsschicht bei etwa 85°C und hoher Luftfeuchtigkeit nicht bekömmlich. Das Zink oxidiert unter diesen Bedingungen relativ rasch und wird pulverig, so dass die Oberfläche der Trommel und der Seitenwände rauh wird. Bei Schlupf des Kabels auf diesen Spulenteilen kann daher die dünne äussere Isolationsschicht, insbesondere im noch nicht vernetzten, relativ weichen Zustand, beschädigt werden. Dadurch geht die innerste Wicklung des Kabels verloren, was zu hohen Verlusten führt.In recent times, energy cables have often been shielded in order to reduce losses. The insulation applied to the shield in the last cable manufacturing operation need only be thin. In the known coils, however, such thin insulation layers are often damaged by the slippage which the cable inevitably suffers on the drum when it cools from the manufacturing temperature to room temperature. Even with careful manufacture, the drums and the side walls are rarely ideally smooth because small welding beads are hardly visible and when in galvanizing, i.e. when they are pulled out of the zinc bath, slag parts are inevitably deposited on the surface of the zinc bath. In addition, the zinc layer is not digestible by the final heat treatment of the cable for crosslinking the outer insulation layer at about 85 ° C and high humidity. The zinc oxidizes relatively quickly under these conditions and becomes powdery, so that the surface of the drum and the side walls becomes rough. If the cable slips on these coil parts, the thin outer insulation layer can therefore be damaged, in particular in the not yet cross-linked, relatively soft state. As a result, the innermost winding of the cable is lost, which leads to high losses.

Es sind bereits demontierbare Spulen bekannt. Deren Seitenwände sind als Faltensegmente ausgebildet, die sich zwischen einem Radreifen und einem inneren Ring erstrecken. Der innere Ring ist wiederum über drei Zentralspeichen mit einem Nabenflansch verbunden. Der Trommelmantel ist ein durchgehender Zylinder, der auf den inneren Ringen zentriert ist. Die gegenüberliegenden Zentralspeichen sind über Zuganker zusammengespannt. Diese bekannte Spule ist schwer und im demontierten Zustand immer noch recht sperrig. Ausserdem weist sie ebenfalls die zuvor ausgeführten Mängel auf.Removable coils are already known. The side walls are designed as fold segments which extend between a wheel tire and an inner ring. The inner ring is in turn connected to a hub flange via three central spokes. The drum shell is a continuous cylinder that is centered on the inner rings. The opposite central spokes are clamped together using tie rods. This known coil is heavy and still quite bulky when disassembled. In addition, it also shows the previously mentioned shortcomings.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, die obigen Nachteile des Standes der Technik zu beseitigen. Diese Aufgabe wird durch die in den Ansprüchen umschriebene Erfindung gelöst.The present invention has for its object to eliminate the above disadvantages of the prior art. This object is achieved by the invention described in the claims.

Nachfolgend wird ein Ausführungsbeispiel der Erfindung anhand der Zeichnung erläutert. Darin zeigt:

  • Fig. 1 einen Axialschnitt durch eine Kabelspule
  • Fig. 2 eine Stirnansicht der Spule,
  • Fig. 3 und 4 ein Detail einer Schraubverbindung, und
  • Fig.5 einen Teilschnitt durch ein Trommelsegment.
An exemplary embodiment of the invention is explained below with reference to the drawing. It shows:
  • Fig. 1 shows an axial section through a cable spool
  • 2 is an end view of the coil,
  • 3 and 4 a detail of a screw connection, and
  • 5 shows a partial section through a drum segment.

In Fig. 1 ist der besseren Uebersicht wegen nur ein Teil der Hälfte eines Axialschnittes durch die Spule dargestellt. Die Spule hat beidseits einen Radreifen 1 mit U-förmigem Querschnitt. Am Reifen 1 sind gleichmässig verteilt 12 radiale Speichen 2 aus C-Profilen angeschweisst. Innen sind sämtliche Speichen 2 mit zwei Nabenflanschen 3 verschweisst, die zentrisch einen tiefgezogenen Ansatz 4 zur Aufnahme eines Lagerzapfens haben. Ueber je eine Schraubverbindung 5 ist jede Speiche 2 mit einer zylindrischen Trommel 6 verbunden. Die Trommel 6 besteht aus vier Viertelkreissegmenten 7. Die Segmente 7 haben an ihren beiden Längsrändern parallel zur Achsrichtung eine U-förmig abgekantete, aneinander anliegende Versteifung 8 (Fig. 4) und an ihren beiden Stirnrändern angeschweisste Rippen 9.In FIG. 1, for the sake of a better overview, only part of the half of an axial section through the coil is shown. The coil has a wheel tire 1 with a U-shaped cross section on both sides. 12 radial spokes 2 made of C-profiles are welded evenly to the tire 1. Inside, all spokes 2 are welded to two hub flanges 3, which have a deep-drawn attachment 4 for receiving a bearing journal. Each spoke 2 is connected to a cylindrical drum 6 by a screw connection 5. The drum 6 consists of four quarter-circle segments 7. The segments 7 have, at their two longitudinal edges parallel to the axial direction, a U-shaped, stiffening stiffener 8 (FIG. 4) and ribs 9 welded to their two end edges.

Die Schraubverbindung 5 zwischen Speiche 2 und Rippe 9 ist in Fig. 3 und 4 detailierter dargestellt: An der Speiche 2 ist ein Auge 14 angeschweisst. In die Bohrung 15 des Auges 14 ist ein Arm 16 mit Nasen 17 an den freien Enden zweier federnder Schenkel 18 eingeschnappt. Dazu ist der der Speiche 2 abgewandte Rand der Bohrung 15 nur geringfügig dicker als der Abstand zwischen den Nasen 17. Der Arm 16 hat an seinem gegenüberliegenden Ende ein Vierkantloch 19. Im Loch 19 ist ein Halter 20 aus dünnem Blech eingeschnappt, der eine Vierkantmutter 21 umschliesst. Durch Durchgangsbohrungen 22, 23 in der Speiche 2 und der Rippe 9 ist eine Schraube 24 in die Mutter 21 eingeschraubt. Benachbart den Bohrungen 22, 23 sind Speiche 2 und Rippe 9 mit einem in der Speiche 2 festsitzenden Stift 25 zentriert. Diese Ausbildung der Schraubverbindung 5 ermöglicht eine einfache Montage. Durch die Zentrierung mit dem Stift 25 wird eine exakte Positionierung des Segmentes 7 erreicht. Nun wird die Mutter 21 mittels des Armes 16 eingeschwenkt und fluchtet damit automatisch mit den Bohrungen 22, 23, so dass die Schraube 24 bequem eingeschraubt werden kann. Beim Anziehen der Schraube 24 wirkt der Arm 16 zudem als Gegenhalteschlüssel.The screw connection 5 between the spoke 2 and the rib 9 is shown in more detail in FIGS. 3 and 4: an eye 14 is welded onto the spoke 2. An arm 16 with lugs 17 is snapped into the bore 15 of the eye 14 at the free ends of two resilient legs 18. For this purpose, the edge of the bore 15 facing away from the spoke 2 is only slightly thicker than the distance between the lugs 17. The arm 16 has a square hole 19 at its opposite end. A holder 20 made of thin sheet metal is snapped into the hole 19. which encloses a square nut 21. A screw 24 is screwed into the nut 21 through through bores 22, 23 in the spoke 2 and the rib 9. Spoke 2 and rib 9 are centered adjacent to the bores 22, 23 with a pin 25 stuck in the spoke 2. This design of the screw connection 5 enables simple assembly. By centering with the pin 25, an exact positioning of the segment 7 is achieved. Now the nut 21 is pivoted in by means of the arm 16 and is thus automatically aligned with the bores 22, 23, so that the screw 24 can be screwed in comfortably. When the screw 24 is tightened, the arm 16 also acts as a counter wrench.

Zwischen der Trommel 6 und der Peripherie des Radreifens 1 sind auf den Speichen 2 sechs Segmente 29 einer Seitenwand 30 mittels Schrauben 32 befestigt. Die Segmente 29 können stattdessen oder zusätzlich mit dem Radreifen 1 und/oder dem Kern 6 verbunden sein und haben Versteifungsrippen 31 in radialer und in Umfangsrichtung und bestehen aus faserarmiertem Kunststoff oder sind kunststoffbeschichtet.Between the drum 6 and the periphery of the wheel tire 1, six segments 29 of a side wall 30 are fastened to the spokes 2 by means of screws 32. The segments 29 can instead or additionally be connected to the wheel tire 1 and / or the core 6 and have stiffening ribs 31 in the radial and in the circumferential direction and consist of fiber-reinforced plastic or are plastic-coated.

Jedes Kernsegment 7 ist einzeln mit einer thermoplastischen Kunststoffolie 36 bespannt. Wie in Fig. 5 dargestellt, hat die Kunststoffolie 36 längs ihren beiden Längsrändern einen durch eine Schweissnaht 37 gebildeten Saum 38, in den ein Stab 39 zum Beispiel aus Aluminium oder GFK eingelegt ist.Each core segment 7 is individually covered with a thermoplastic plastic film 36. As shown in Fig. 5, the plastic film 36 has along its two longitudinal edges a seam 38 formed by a weld seam 37, in which a rod 39 is inserted, for example made of aluminum or GRP.

Der Stab 39 ist mit einer Reihe von Federn 40 gegen eine auf das Segment 7 aufgeschweisste Leiste 41 mit einer Serie von Bohrungen 42 abgespannt.The rod 39 is braced with a series of springs 40 against a bar 41 welded onto the segment 7 with a series of bores 42.

Durch die Kunststoffolie 36 und die Kunststoffwand 30 ist das Wickelgut optimal geschützt. Bei Beschädigung der Wand 30 oder der Folie 36 können diese Teile leicht ausgewechselt werden.The winding material is optimally protected by the plastic film 36 and the plastic wall 30. If the wall 30 or the film 36 is damaged, these parts can easily be replaced.

Gelegentlich werden Spulen beim Ab- oder Aufwickeln auf konischen Zapfen gelagert, die mit einer relativ grossen Kraft gegeneinander pressen. Um diese Kräfte aufnehmen zu können, hat die Spule ein zentrales Achsrohr 47, das mittels zweier Stifte 48 am inneren Nabenflansch 4 positioniert ist. Das Achsrohr 47 kann zusätzlich beidseits einen Endflansch haben und mit den Nabenflanschen 4 verschraubt sein. Mit diesem Achsrohr 47 werden einseitig wirkende Axialkräfte zum Beispiel bei hochkant stehender Spule auf beide Speichenkränze verteilt, so dass die Spule auch als Maschinenspule zum Beispiel beim Verseilen von Kabeln eingesetzt werden kann. Für diesen Anwendungsfall kann auch zusätzlich der in Fig. 1 dargestellte zentrale Speichenkranz 49 montiert werden. Das Achsrohr 47 hat mittig einen Mittelflansch 50. Mit dem Mittelflansch 50 sind kürzere Speichen 52 verschraubt. Jede Speiche 52 ist mit einer weiteren Schraubverbindung 5 gemäss Fig. 3 und 4 mit einer Mittelrippe 53 verbunden. Der Speichenkranz 49 stützt die Trommel 6 mittig ab und überträgt einen Teil der Axiallast auf die Trommel 6, so dass die Spule mit dieser Ergänzung auch bei schwererem Wickelgut als Maschinenspule verwendbar ist. Gelangt sie nur als Transportspule zum Einsatz, so kann das Achsrohr 47 und der Speichenkranz 49 weggelassen und somit das Taragewicht der Spule reduziert werden.Occasionally, spools are stored on conical pins during unwinding or winding, which press against one another with a relatively large force. In order to be able to absorb these forces, the coil has a central axle tube 47, which is positioned on the inner hub flange 4 by means of two pins 48. The axle tube 47 can additionally have an end flange on both sides and can be screwed to the hub flanges 4. With this axle tube 47, axial forces acting on one side, for example when the coil is upright, are distributed to both spoke rings, so that the coil can also be used as a machine coil, for example when stranding cables. For this application, the central spoke rim 49 shown in FIG. 1 can also be installed. The axle tube 47 has a central flange 50 in the center. Shorter spokes 52 are screwed to the central flange 50. Each spoke 52 is connected to a further screw connection 5 according to FIGS. 3 and 4 with a central rib 53. The spoke ring 49 supports the drum 6 in the middle and transmits it a part of the axial load on the drum 6, so that the spool can be used with this addition as a machine spool even with heavier winding material. If it is only used as a transport spool, the axle tube 47 and the spoke ring 49 can be omitted and the tare weight of the spool can thus be reduced.

Durch die beschriebene Ausbildung der Spule wird eine leichte Montier- und Reparierbarkeit erreicht. Die Kraftübertragung von den Lagerzapfen auf die Trommel ist durch die vielen Speichen gut, so dass die Speichen und die Endrippen der Trommel relativ leicht gebaut werden können. Die Spule beansprucht im demontierten Zustand sehr wenig Raum und kann daher zur Erstverwendung kostengünstig versandt und gelagert werden.The described design of the coil makes it easy to assemble and repair. The power transmission from the trunnion to the drum is good due to the many spokes, so that the spokes and the end ribs of the drum can be built relatively easily. The coil takes up very little space when disassembled and can therefore be inexpensively shipped and stored for first use.
