Description
Werkzeug zum Auseinandernehmen von Rohrleitungen Die Rohre von Rohrleitungen, insbesondere für Heizungszwecke, werden bekanntlich unter Einfügung von Dichtungen fest zusammengeschraubt. Befinden sich solche Rohre jahrelang in diesem Zustand, so wird die Dichtung hart, und sie verbindet sich so fest mit dem Metall der Rohre, da:ß ein Auseinandernehmen nur durch Eintreiben von Keilen zwischen die Dichtungsflächen :einen ETfolg verspricht. Diese Arbeit ist lohne Beschädigung der Dichtungsflächen sielten auszuführen.Tool for dismantling pipelines The pipes of pipelines, especially for heating purposes, are known to include the insertion of seals firmly screwed together. If such pipes are in this condition for years, so the gasket becomes hard, and it bonds so firmly to the metal of the pipes, because: ß can only be taken apart by driving wedges between the sealing surfaces : promises an ET success. This work is without damaging the sealing surfaces they were supposed to carry out.
Dieser Nachteil wird durch das den Gegenstand der Erfindung bildende Werkzeug, das in der Zeichnung in einem Ausführungsbeispiel dargestellt ist, vermieden. Das neue Werkzeug besteht aus zwei an. .den voneinander zu trennenden Rohren zu befestigenden Schiellen, die mit Muttern in Verbindung stehen, in die eine Rechts- und Linksgewinde aufweisende Gen rindespindel eingeschraubt ist. Durch Drehen der Gewindespindel werden die Muttern und die Schellen sowie dadurch die von den Schellen. fest umklammerten Rohre zwangsläufig auseinandergezogen.This disadvantage is caused by that which forms the subject of the invention Tool, which is shown in the drawing in one embodiment, avoided. The new tool consists of two. .to the pipes to be separated from each other fastening straps, which are connected with nuts, into which a right and left-hand threaded gene corkscrew is screwed in. By turning the The nuts and the clamps as well as the clamps are threaded spindle. tightly gripped pipes inevitably pulled apart.
Die Zeichnung zeigt das an zwei Rohren a. befestigte Werkzeug in Seitenansicht (Fig. i ) und in einem Schnitt (Fig. 2). Die Fig.3 und .4 zeigen Einzelheiten eines weiteren @#lusführungsbeispiels.The drawing shows that on two pipes a. fortified tool in side view (Fig. I) and in a section (Fig. 2). The Fig.3 and .4 show details of a further @ # example.
An jedem Rohr a beiderseits einer Flatischverbindun:g wird nach Lösen ihrer Verschraubung eine Schelle b befestigt. Jede aus zwei 'feilen zusammengesetzte Schelle b ragt in einen Ausschnitt d eines Armes c hinein, der an seinem Ende in eine Mutter e übergeht. Zum Zusammenn:ehen der Schelle b und zum Befestigen der Schelle in der Aussparung d des Armes e d:lenen drei Schraubenbolzcn f mit Muttern ä. In die beiden am Ende der Arme c befindlichen Muttern e ist eine mit Rechts- und Linksgewinde versehene Gcwindespindel lt eingeschraubt, die z. B. mittels eines am Kopf i angreifenden Schraubenschlüssels gedreht werden kann. Wird die Gewindespindel in Richtung des in Fig. 2 eingezeichneten Pfeiles x gedreht, so werden di;-Muttern e und die damit in fester Verbindtiii;; stehenden Schellen .b nach außen bewegt, bis der Zusammenhalt zwischen dien Rohren a an dier früheren Flanschverbiladungsstelle aufgehoben ist.After loosening its screw connection, a clamp b is attached to each pipe a on both sides of a flat connection. Each clamp b, composed of two files, protrudes into a section d of an arm c, which at its end merges into a nut e. To assemble the clamp b and to fix the clamp in the recess d of the arm ed: len three screw bolts f with nuts Ä. A screw spindle lt with right and left threads is screwed into the two nuts e at the end of the arms c , the z. B. can be rotated by means of a wrench acting on the head i. If the threaded spindle is rotated in the direction of the arrow x drawn in FIG. 2, then di; nuts e and the securely connected thereto; standing clamps .b moved outwards until the cohesion between the pipes a at the earlier flange connection point is canceled.
Jede Schielle b kann, wie die Fig. 3 und .f in: Seiten- und Stirnansicht zeigen, auch aus zwei am Arm c um einen an#,-enietetcn Bolzen k schwenkbaren Schellenhälften in bestehen, die .am freien Ende mittels B0,1zrii und Mutter zusammengezogen werden können. Diese Ausführungsfarm der Erfindung hat den Vorteil, daß man für die Befestigung des Werkzeugs nur zwei Schrauben zu hisen hat, um die Klappschelle an. den Roltr#,n a anbringen zu können.Each tray b can, like FIGS. 3 and .f in: side and front view show, also of two clamp halves pivotable on arm c around a bolt k on #, - riveted in exist, which are pulled together at the free end by means of B0,1zrii and nut can. This embodiment of the invention has the advantage that one for the attachment of the tool only has to hoist two screws to attach the hinged clamp. den Roltr #, n a to be able to attach.
