System- und ZeichnunpsbeschreibungSystem and drawing description
Es gibt diverse Systeme zum aktivierten Verdichten, Bohren, Abtragen, Fräsen, Schälen und dgl. von Gestein, Beton, Asphalt oder sonstigen Mineralien. Die erfindungsgemäßen Systeme haben den Vorteil, daß sie durch ihre Aktivierung einen um wenigstens 50 % geringeren Antriebs-, Andruck- und Vortriebsbedarf haben - in einer Version bei optimaler Auswuchtung sogar absolut schwingungsfrei laufen - wesentlich leichtere Maschinen erfordern, erfahrungsgemäß jegliche Gesteinsarten und -härten bearbeiten können und noch dazu mit vergleichsweise hohen Geschwindigkeiten arbeiten - als Walzen ausgebildet speziell geeignet sind zum Abtragen von Straßendecken - und in Kugelform besonders geeignet für sogenannte Teilschnitt- / Auslegermaschinen; - für beide Anwendungen wird gesonderter Schutz beantragt - insbesondere aber für die erfindungsgemäße extrem kompakte Konstruktion / Kombination, die andererseits aber auch eine besonders breite Arbeitsfläche ermöglicht. - Die Walzen, Kugeln oder dgl. erhalten ihren Schlageffekt über Exzenter und/oder Unwuchten einer angetriebenen schnellaufenden Kurbelwelle oder Hülse, z.B. mit 4.000 U/min = 4.000 Schläge/min bei einer Amplitude von z.B. 5 mm. Die auf der Kurbelwelle oder Exzenterhülse drehende, außen zweiseitig gelagerte Walze, Kugel von z.B. 400 mm Durchmesser kann hierbei getrennt angetrieben werden - z.B. mit 100 U/min - über Kette, Keilriemen, Zahnräder oder dgl.; aber auch ohne Antrieb rotieren z.B. mit Disken versehene Walzen langsam gegenläufig zur Drehrichtung der Exzenterwelle bzw. -hülse. -Gegengewichte zur Auswuchtung sind nachjustierbar - vorzugsweise von außen.There are various systems for activated compaction, drilling, ablation, milling, peeling and the like of rock, concrete, asphalt or other minerals. The systems according to the invention have the advantage that their activation means that they require at least 50% less drive, pressure and propulsion - in one version with optimal balancing they even run absolutely free of vibrations - require considerably lighter machines, experience has shown that they can process any type of rock and hardness can and also work at comparatively high speeds - designed as rollers are particularly suitable for removing road surfaces - and in spherical form particularly suitable for so-called partial cut / boom machines; - Separate protection is requested for both applications - but especially for the extremely compact construction / combination according to the invention, which on the other hand also enables a particularly wide working surface. - The rollers, balls or the like receive their impact effect via eccentrics and / or unbalances of a driven high-speed crankshaft or sleeve, e.g. at 4,000 rpm = 4,000 beats / min with an amplitude of e.g. 5 mm. The roller that rotates on the crankshaft or eccentric sleeve and has two bearings on the outside, e.g. 400 mm diameter can be driven separately - e.g. at 100 rpm - via chain, V-belt, gear wheels or the like; but also rotate without drive e.g. Discs with rollers slowly reverse to the direction of rotation of the eccentric shaft or sleeve. Counterweights for balancing can be readjusted - preferably from the outside.
