Abstract
Description
"Gerät zum Lösen oder Schließen von festsitzenden"Device for loosening or closing stuck
Rohrverschraubungen" Die Erfindung betrifft ein Gerät zum Lösen oder Schließen von festsitzenden Rohrverschraubungen. Pipe fittings "The invention relates to a device for loosening or Closing stuck pipe fittings.
Festsitzende Verschraubungen kommen vor allen Dingen bei Heizanlagen, aber auch bei Pumpen etc. vor.Stuck screw connections are particularly common in heating systems, but also with pumps etc. before.
Um bei einer Reparatur solche, meist eingerostete Rohrverschraubungen zu lösen, (mit der Zange oder dem Schlüssel allein geht es nicht), setzt der Monteur einen Meisel an das Sechskant der Verschraubung an, ein paar kurze Schläge, und sc hon löst sich die Verschraubung. Dabei leidet natürlich die Verschraub= ung und muß von Fall zu Fall erneuert werden. Dieses Vorgehen verteuert natürlich die Montage erheblich.In order to repair such, mostly rusted, pipe fittings to solve (with the pliers or the key alone it is not possible), the fitter sets a chisel on the hexagon of the screw connection, a few short blows, and sc hon loosens the screw connection. Of course, the screwing also suffers must be renewed on a case-by-case basis. This procedure of course makes the assembly more expensive considerable.
Die Erfindung ist nun darauf abgestellt, diesen Vor= gang zu vereinfachen und das Lösen oder Befestigen einer solchen Verschraubung, ohne Meisel und ohne Beschädigung der Verschraubung zu bewerkstelligen.The invention is now aimed at simplifying this process and loosening or fastening such a screw connection without Chisel and can be done without damaging the screw connection.
Zu diesem Zweck ist ein Werkzeug vorgesehen, mit dem man das Sechskant der Verschraubung voll erfassen kann wie mit einer Zange oder einem Schlüssel, und die Lösung der Verschraubung mit ein paar Hammer= schläge auf den am Werkzeug angebrachten Dorn, schnell und bequem zu erreichen. Eine Beschädigung der Verschraubung ist dabei ausgeschlossen und die Arbeit geht schnett vonstatten.For this purpose a tool is provided with which you can remove the hexagon the screw connection can fully grasp like with a pair of pliers or a wrench, and the loosening of the screw connection with a couple of hammer blows on the one attached to the tool Dorn, quick and easy to reach. Damage to the screw connection is involved excluded and the work is going smoothly.
Die Zeichnung veranschaulicht das Gerät in bei= spielsweiser Ausführung. Es zeigen: Fig.l eine Seitenansicht, Fig.2 eine Draufsicht,bzw. Stirnansicht, Fig.3 eine Draufsicht auf das Werkzeug, angesetzt an einer Rohrverschraubung.The drawing illustrates the device in an example version. They show: FIG. 1 a side view, FIG. 2 a plan view, or Front view, Fig. 3 a top view of the tool attached to a pipe fitting.
Das Gerät besteht aus einer zweiteiligen Backe 1, die ein Gelenk 3 ha - w ..raubung 4 mit vlügelmutter.Die gescnlossenen backen 1 haben an (It:£ Innenseite einen Secbskaslt 2 entsprechend einer Rohrverschraubung 7, 8, 9. An einer Seite der Backen 1 ist ein Dorn 5 vorgesehen, der mittels Gewinde 6 am Backen befestigt ist. Die Richtung des Dorns weicht nur wenig ab von der Mittelachse der Backen 1.The device consists of a two-part jaw 1 that has a joint 3 ha - w .. screw connection 4 with wing nut. The closed jaws 1 have on (It: £ inside a Secbskaslt 2 corresponding to a pipe screw connection 7, 8, 9. On one side the jaw 1 is provided with a mandrel 5 which is fastened to the jaw by means of a thread 6 is. The direction of the mandrel deviates only slightly from the central axis of the jaws 1.
Die Funktion: Man öffnet die Backen 1, indem man die Verschraubung 4 löst, schiebt das Werkzeug über die Rohrverschraub= ung 9 so, daß das Sechskant 2 das Sechskant der Ver= schraubung 9 umschließt. Dann schließt man die Ver= schraubung 4 und Durch ein paar kurze Schläge mit dem 7cr auf den Dorn 5 läßt sich die Rohrverschraul)ung am Rohr 7 ganz leicht lösen. Der Dorn 5 steht nur in seiner Richtung ein wenig ab von der Mittelachse des Sechskants 2. Dies ist wichtig für die Wirkung der Hammerschläge auf das Lösen der Verschraubung9, da ja die DRehung der Ver= schraubung 9 beeinflußt werden soll.The function: You open the jaws 1 by loosening the screw connection 4, slide the tool over the pipe screw connection 9 so that the hexagon 2 surrounds the hexagon of the screw connection 9. Then you close the screw connection 4 and With a few short blows with the 7cr on the mandrel 5, the pipe screwing on the pipe 7 can be easily loosened. The mandrel 5 only protrudes a little from the central axis of the hexagon 2 in its direction. This is important for the effect of the hammer blows on the loosening of the screw connection 9, since the D-extension of the screw connection 9 is to be influenced.
Bei diesem Verfahren wird die Rohr verschraubung nicht beschädigt und die Arbeit geht zügig voran. Umgekehrt kann durch Aufsetzen des Werkzeugs in entgegengesetz= ter Richtung, auch eine Rohrverschraubung gut be= festigt werden, namentlich auch dann, wenn die beiden zusammenstoßenden Rohre 7 nicht genau achsial zu= einander ausgerichtet sind. Hier muß die Verschraubung 9 besonders gut festgezogen werden.This procedure does not damage the pipe fitting and the work is proceeding briskly. Conversely, by placing the tool in in the opposite direction, a pipe union must also be well fastened, especially when the two colliding tubes 7 are not exactly axially to = are aligned with each other. Here the screw connection 9 must be tightened particularly well will.
Der Dorn 5 besteht zweckmäßig aus gehärtetem Stahl.The mandrel 5 is expediently made of hardened steel.
Zur beliebigen Schrägstellung des Dornes 5 ist der= selbe hinter dem Gewinde 6 mit einem Gelenk versehen.For any inclination of the mandrel 5 is = the same behind the Thread 6 provided with a joint.
