Description
Ziehkopf für die Verlegung elektrischer Kabel, der insbesondere für schwere Mehrleiterstarkstromkabel geeignet ist Die Erfindung betrifft einen Ziehkopf für die Verlegung elektrischer Kabel, der insbesondere für schwere Mehrleiterstarkstromkabel, wie beispielsweise ölkabel oder Gasdruckkabel, geeignet ist. Um eine sichere Erfassung der Adern zu gewährleisten und dabei eine Beschädigung des Mantels zu verhüten, sind in dem Ziehkopf erfindungsgemäß die Kabeladern, der Kabelmantel und gegebenenfalls die Bewehrung gesondert eingespannt und gemeinsam am Zug beteiligt. Vorzugsweise werden dabei die Kabeladern mit Hilfe von Keilen in dem Ziehkopf eingespannt.Pulling head for laying electrical cables, especially for Heavy multi-conductor power cables are suitable. The invention relates to a pulling head for laying electrical cables, especially for heavy multi-conductor high-voltage cables, such as oil cables or gas pressure cables, is suitable. To ensure a safe capture to ensure the veins and to prevent damage to the sheath, are in the pulling head according to the invention, the cable cores, the cable sheath and optionally the reinforcement is clamped separately and jointly involved in the pull. Preferably the cable cores are clamped in the pulling head with the help of wedges.
Die Erfindung ist an Hand der Zeichnung näher erläutert, die einen Querschnitt durch ein Ausführungsbeispiel eines Ziehkopfes gemäß der Erfindung darstellt.The invention is explained in more detail with reference to the drawing, which one Represents cross section through an embodiment of a pulling head according to the invention.
Der Ziehkopf nach dieser Zeichnung besteht im wesentlichen aus einem zylindrischen Mittelteil 1, in dem das Kabel abgefangen ist und auf den eine Kappe 2 aufgeschraubt ist, an der das Zugseil 3 angreift. In der nach vorn konisch erweiterten Bohrung des Mittelteiles 1 sind die abgemantelten Adern 4 des Kabels mit Hilfe eines konischen Mittelkeiles 5 und dreier Außenkeile 6 eingespannt. Der Mittelteil 1 des Ziehkopfes hat an seinem kabelseitigen Ende eine konische Ansatzfläche 7, auf der das Ende des Metallmantels 8 des Kabels mit Hilfe eines Klemmringes 9 und einer überwurfmutter 10 eingespannt ist. Falls das Kabel außerdem mit einer zugfesten Bewehrung versehen ist, kann diese Bewehrung 11 ebenfalls zwischen zwei weiteren Klemmringen 12 und 13 mittels einer weiteren überwurfmutter 14 im Ziehkopf erfaßt und am Zug beteiligt werden.The pulling head according to this drawing consists essentially of a cylindrical central part 1 in which the cable is intercepted and on which a cap 2 is screwed, on which the pulling cable 3 engages. The stripped cores 4 of the cable are clamped with the aid of a conical central wedge 5 and three outer wedges 6 in the bore of the central part 1, which is widened conically towards the front. The middle part 1 of the pulling head has a conical attachment surface 7 at its cable-side end, on which the end of the metal jacket 8 of the cable is clamped with the aid of a clamping ring 9 and a union nut 10. If the cable is also provided with tensile reinforcement, this reinforcement 11 can also be grasped between two further clamping rings 12 and 13 by means of a further union nut 14 in the pulling head and involved in the pulling.
Um eine gegenseitige Verdrehung zwischen Kabel und Zugseil zu ermöglichen und dadurch Torsionsbeanspruchungen des Kabels beim Ziehen zu vermeiden, empfiehlt es sich, die Spitze der Kappe 2, an der das Seil 3 angreift, drehbar zu befestigen, was bei dem dargestellten Ausführungsbeispiel durch das Kugellager 15 erreicht ist.In order to allow a mutual twisting between the cable and the pulling rope and thereby avoid torsional stresses on the cable when pulling, it is advisable to fasten the tip of the cap 2, on which the rope 3 engages, rotatably, which in the illustrated embodiment by the ball bearing 15 is reached.
Der Ziehkopf kann durch die Entlüftungsschraube 16 nach vollendeter Montage entlüftet sowie an ein öldruckausgleichsgefäß angeschlossen werden. Die Montage und Demontage ist also an keine Zeit gebunden.The pulling head can be vented through the vent screw 16 after assembly is complete and connected to an oil pressure equalization vessel. The assembly and disassembly is therefore not tied to any time.
Um ein sicheres Erfassen der Kabeladern im Zichkopf zu erzielen, empfiehlt sich, die Innenbohrung des Mittelteiles 1 zu rillen. Gegebenenfalls können auch die Keile mit einer rauhen Oberfläche versehen werden.In order to achieve a secure gripping of the cable cores in the drawing head, it is advisable to groov the inner bore of the middle part 1. If necessary, the wedges can also be provided with a rough surface.
Der Zichkopf gemäß der Erfindung kann am Montageort ohne Schwierigkeiten angebracht werden, da zu seiner Montage keinerlei Wärmeanwendung für Lötarbeiten erforderlich ist. Ein Ziehkopf gemäß der Erfindung gestattet außerdem die Durchführung der Verlegearbeiten unter vollem Betriebsdruck des Kabels.The drawing head according to the invention can be used at the installation site without difficulty be attached, since no heat is used for soldering to assemble it is required. A pulling head according to the invention also allows implementation the laying work under full operating pressure of the cable.
