Description

Es sind bereits Vorrichtungen zum Zentrieren von miteinander zu verschweißenden Rohren bekannt, die in die zu verbindenden Rohre eingeschoben werden und mittels an deren Innenwandung anzudrückender Klemmbacken die Rohre zentrieren. Bei diesen bekannten Vorrichtungen werden die Klemmbacken hydraulisch bewegt. Sie sind daher in ihrem Aufbau verwickelt, schwer von Gewicht und sind ihrer Bauart nach lediglich für Rohre größeren Durchmessers bestimmt.There are already devices for centering to be welded together Known pipes that are inserted into the pipes to be connected and by means of Center the pipes on the inner wall of the clamping jaws to be pressed. With these known devices, the jaws are moved hydraulically. You are therefore entangled in construction, heavy in weight, and mere construction intended for pipes of larger diameter.

Demgegenüber besteht die Vorrichtung zum Zentrieren von Flanschen und Rohren gemäß der Erfindung aus einer in Rohr und Flansch einzuschiebenden Trommel mit spreizkopfartig nach außen herausdrückbaren Klemmbacken, die durch Spindel und Mutter aus- und eingefahren werden können.In contrast, there is the device for centering flanges and pipes according to the invention from a drum to be pushed into the pipe and flange with clamping jaws that can be pushed outwards like an expanding head, which are driven by the spindle and Nut can be extended and retracted.

In der Zeichnung ist eine Ausführungsform der Vorrichtung nach der Erfindung wiedergegeben. Fig. r zeigt sie im Längsschnitt, Fig. 2 im Querschnitt; Fig. 3 zeigt die Vorrichtung eingefahren in Rohr und Flansch.In the drawing is an embodiment of the device according to Invention reproduced. Fig. R shows it in longitudinal section, Fig. 2 in cross section; Fig. 3 shows the device retracted in the tube and flange.

In einer Trommel r ist zentrisch eine Gewindespindel 2 gelagert. Durch Drehen der Spindel werden Muttern 3 in der Richtung der Spindelachse verschoben, die an mehreren versetzt angeordneten Hebeln 4 Klemmbacken 5 trägen, die durch Schlitze 6 der Trommel hindurchragen. Die Vorrichtung wird mit eingezogenen Klemmbacken in Rohr und Flansch eingeführt; durch Drehen der Spindel und das dadurch bewirkte Spreizen der Hebel 4 werden die Klemmbacken 5 nach außen gedrückt, bis sie sich an die Innenwände von Rohr 7 und Flansch 8 anlegen, diese damit gegeneinander zentrieren und festhalten. Durch Drehen der Spindel in umgekehrter Richtung werden die Klemmbacken wider eingezogen, so daß die Vorrichtung leicht aus Rohr und Flansch herausgezogen werden kann.A threaded spindle 2 is mounted centrally in a drum r. By Turning the spindle, nuts 3 are moved in the direction of the spindle axis, the 4 jaws 5 carry on several offset arranged levers, which through slots 6 of the drum protrude. The device is inserted with the jaws retracted in Tube and flange inserted; by turning the spindle and the spreading caused by it the lever 4, the jaws 5 are pressed outward until they touch the inner walls of pipe 7 and flange 8, center them against each other and hold them in place. By turning the spindle in the opposite direction, the clamping jaws are retracted again, so that the device can be easily pulled out of the tube and flange.

Das Gerät ist für verschiedene Rohrdurchmesser verwendbar.The device can be used for different pipe diameters.
