KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die vorliegende Erfindung betrifft ein Werkzeug zum Rohrausziehen bezw. zum leichteren Entfernen von Röhren aus Röhrenkesseln u. dgl.The present invention relates to a tool for pipe extraction BEZW. for the easier Removal of tubes from tubular boilers and the like.
In der beiliegenden Zeichnung ist die Erfindung zur Darstellung gebracht worden.The invention has been illustrated in the accompanying drawing.
Fig. ι zeigt eine Seitenansicht der Angriffsstelle des Rohrausziehers innerhalb eines im Schnitt gezeichneten Rohres; Fig. 2 zeigt eineFig. Ι shows a side view of the point of attack of the pipe extractor within an im Cut of drawn pipe; Fig. 2 shows a
ίο Seitenansicht des Rohrausziehers; Fig. 3 zeigt eine Ansicht des ganzen Ausziehbolzens, und die Fig. 4, 5 und 6 zeigen die exzentrisch gelagerten geriffelten Angriffsscheiben des Rohrausziehers.ίο side view of the pipe extractor; Fig. 3 shows a view of the entire extraction bolt, and FIGS. 4, 5 and 6 show the eccentric grooved attack disks of the pipe extractor on bearings.
Der Rohrauszieher besteht aus einem Schaft a mit einem als Führung dienenden Bund b und einem als Vierkant ausgebildeten Kopfe c. Von den Angriffsscheiben d, e und f sind die mittlere Scheibe e fest bezw. nicht drehbar, die beiden anderen Scheiben dundf dagegen drehbar, und zwar exzentrisch auf dem Schaftende angeordnet, und werden hier mittels der Platte g und Schraubenmutter i in Stellung gehalten.The pipe extractor consists of a shaft a with a collar b serving as a guide and a square head c. Of the attack disks d, e and f , the middle disk e are fixed respectively. not rotatable, the other two disks dundf, on the other hand, rotatable, namely eccentrically arranged on the shaft end, and are held in position here by means of plate g and screw nut i.
In Fig. ι ist gezeigt, wie der Rohrauszieher zur Anwendung kommt, k stellt eine Wand dar, in welcher ein Rohr / hineingeschraubt worden ist. Soll nun dies Rohr / entfernt bezw. herausgezogen werden, so wird der Rohrauszieher so weit in das Rohr hineingesteckt, daß der Führungsansatz b mit der Rohrmündung abschließt, und das Werkzeug wird mittels einer auf das Vierkant c gesteckten Kurbel o. dgl. in der Pfeilrichtung gedreht. Durch diese Drehung des Werkzeuges greifen die geriffelten Scheiben die Innenwandung des Rohres an bezw. klemmen sich fest und bewirken, daß das hineingeschraubte Rohrende so weit zurückgedreht wird, daß nach Aufhören des Schraubengewindes das Rohr schlank herausgezogen werden kann.In Fig. Ι it is shown how the pipe extractor is used, k represents a wall in which a pipe / has been screwed. Should this pipe / removed respectively. be pulled out, the Rohrauszieher is so far inserted into the tube, that the guide projection b is flush with the pipe opening, and the tool is rotated on the square c plugged crank o. the like. in the direction of the arrow by means of a. Through this rotation of the tool, the corrugated disks attack the inner wall of the pipe and / or. clamp and cause the screwed-in pipe end to be turned back so far that after the screw thread has ceased, the pipe can be pulled out slim.
Dasselbe Werkzeug kann zum Hineinbringen der Rohre verwendet werden, indem die entgegengesetzte Drehrichtung ebenfalls die Angriffsscheiben mit der Rohrwand in feste Verbindung zu bringen vermag.The same tool can be used to bring the pipes in by the opposite one Direction of rotation is also able to bring the attack disks into firm connection with the pipe wall.
