Description

Vorrichtung zum Entfernen des Kesselsteins von der Innenwandung von Dampfkesselröhren. Die Erfindung bezieht sich auf eine Vorrichtung zum Entfernen des Kesselsteins von der Innenwandung von Dampfkesselröhren mit auf einer in schnelle Umdrehung versetzten Spindel angeordneten fräserartigen Werkzeugen.Device for removing the scale from the inner wall of Steam boiler tubes. The invention relates to a device for removing of the boiler stone from the inner wall of steam boiler tubes with on one in rapid Rotation offset spindle arranged milling cutter-like tools.

Das Neue gegenüber Vorrichtungen ähnlicher Art besteht darin, da$ die die Werkzeuge aufnehmende Spindel -aus mehreren gegeneinander versetzt angeordneten elliptischen Teilen zusammengesetzt ist, die senkrecht zur Längsachse gegeneinander verschiebbar sind.The novelty compared to devices of a similar type is that $ the spindle accommodating the tools - made up of several offset from one another elliptical parts is composed, which are perpendicular to the longitudinal axis against each other are movable.

Die Verschiebung kann dabei in schwalbenschwanzartigen Führungen geschehen.The shift can take place in dovetail-like guides.

Diese Ausbildung .hat gegenüber Bekanntem den Vorteil, daB die Werkzeuge gleichachsig auf der Spindel angebracht werden können, da sie sich bei der Umdrehung von selbst exzentrisch gegeneinander einstellen.This training has the advantage over familiar ones that the tools can be mounted coaxially on the spindle, since they are rotating when rotating automatically adjust eccentrically to each other.

Bei den bekannten Vorrichtungen dieser Art sind u. a. die Werkzeuge um i8o° versetzt an-_ geordnet. Wenn sie daher einzelne Stücke des Kesselsteins absprengen, so setzen diese sich in den Werkzeugen fest und verhindern die Drehung. Der Umdrehungswiderstand des Fräserkopfes wird daher erheblich erhöht, und ein Brechen der biegsamen Antriebswelle kann dadurch herbeigeführt werden.In the known devices of this type, inter alia. the tools arranged offset by 180 °. Therefore, if they have individual pieces of the boiler stone blast off, they get stuck in the tools and prevent rotation. The rotation resistance of the cutter head is therefore greatly increased, and breakage the flexible drive shaft can thereby be brought about.

Bei der Benutzung dieser Vorrichtung werden auch Erschütterungen der Rohrwände vermieden, da, .die Werkzeuge nach beiden Seiten arbeiten.When using this device, vibrations of the Pipe walls avoided because the tools work on both sides.

In der Zeichnung ist eine Ausführungsform der Vorrichtung dargestellt. Es zeigen Abb. i -einen Längsschnitt, Abh. 2 eine Seitenansicht, Abb. 3 einen Querschnitt durch die Arbeitsspindel, Abb. q. eine Draufsicht.In the drawing, an embodiment of the device is shown. Fig. 1 shows a longitudinal section, Fig. 2 shows a side view, Fig. 3 shows a cross section through the work spindle, Fig. q. a top view.

Die Werkzeugspindel, die mittels einer biegsamen Welle angetrieben-wird, besteht aus den elliptischen Teilen a, b und c, d, wovon die Teile a, b bzw. c, d gleich angeordnet und mittels Bolzen i - gegen Verdrehen gesichert sind, während die Teile b und c gegeneinander versetzt angeordnet sind. Die Verschiebung ' der Teile b und c gegeneinander erfolgt durch die schwalbenschwanzartigen Führungen e. Die zwischen den Teilen a und b bzw. c und d angeordneten fräserartigen Werkzeuge f und g sind auf den Bolzen h gelagert und mittels der Stifte i mit den Bolzen h fest verbunden.The tool spindle, which is driven by means of a flexible shaft, consists of the elliptical parts a, b and c, d, of which the parts a, b and c, d are arranged identically and secured against rotation by means of bolts i - while the Parts b and c are arranged offset from one another. The displacement of parts b and c relative to one another takes place through the dovetail-like guides e. The milling cutter-like tools f and g arranged between parts a and b or c and d are mounted on bolts h and are firmly connected to bolts h by means of pins i.
