Description

Rüttel- und Stampfvorrichtung mit Wechselstromantrie6 Die Erfindung betrifft eine Rüttel- oder Stampfvorrichtung mit Wechselströmantrieb. Derartige Vorrichtungen sind hohen Beanspruchungen in der Benutzung ausgesetzt. Da sie im wesentlichen nur im Freien, wie auf Baustellen usw., henutzt werden!, urnberd@i,egen sie allen Witterungseinflüssen. Bei Nichtgebrauch werden sie auf den Boden gestellt oder umgelegt. Sie müssen allen Beanspruchungen, die ein rauher Betrieb, wie z. B. der Straßenbau, mit sich bringt, gerecht werden. Andererseits wird verlangt, daß die Bedienungsperson gegen die in Anwendung kommenden Starkströme auch bei nassem Wetter genügend geschützt wird. Schließlich wird gerade bei Rüttelvorrichtungen, so bei Innenrüttlern, eine hohe Arbeitsfrequenz gefordert; nur bei Anwendung hoher Arbeitsfrequenzen entsteht eine Rüttlung, die die Betonmassen vollkommen zum Fließen bringt bzw. verdichtet.Vibrating and tamping device with alternating current drive6 The invention relates to a vibrating or tamping device with an alternating current drive. Such Devices are exposed to high stresses in use. Since they are in essentially only be used outdoors, such as on construction sites, etc. !, urnberd @ i, egen them all weather influences. When not in use, they are placed on the floor or turned over. They have to withstand all stresses caused by rough operation, such as B. the road construction, brings with it, be fair. On the other hand, it is required that the operator against the high currents in use even when it is wet Weather is sufficiently protected. After all, when it comes to vibrating devices, so with internal vibrators, a high working frequency is required; only when using higher Working frequencies create a vibration that allows the concrete to flow completely brings or condenses.

Die Erfindung beschränkt sich dabei auf Rütbe,l- oder Stampfvonnichtun!gen mit Wwchselstromantrieb. Erfindungsgemäß ist dem mit dem Gerät gekuppelten oder in anderer Übertragungsform (z. B. Biegewelle) zusammengebauten Antriebsmotor ein Umformer vorgeschaltet, der die Frequenz des Wechselstromes zwecks Erreichens einer hohen Arbeitsfrequenz atrf 15o Hvrtz erhöht und glet.ich,zeitig die Spannung auf eine das Leben der Bedienungsperson nicht gefährdende Spannung,. z. B. unter 65 Volt, herabsetzt. An Stelle des vorhandenen Netzes und des Umformers kann auch ein entsprechender Stromerzeuger Verwendung finden.The invention is limited to rubbing, oil or tamping devices with alternating current drive. According to the coupled with the device or a drive motor assembled in another form of transmission (e.g. flexible shaft) Upstream converter that adjusts the frequency of the alternating current in order to achieve a high working frequency atrf 15o Hvrtz increases and glet.ich, early the voltage a voltage that does not endanger the life of the operator. z. B. under 65 Volts, lowers. Instead of the existing network and the converter, a find appropriate power generator use.

Es ist bekannt, daß zur Sicherheit der Bedienungsperson besondere Schutzmaßnahmen notwendig sind, sofern die Spannung gegen Erde 65 Volt überschreiten kann.It is known that for the safety of the operator special Protective measures are necessary if the voltage to earth exceeds 65 volts can.

Man hat ferner bei transportablen Elektrowerkzeugen, wie Schleif- und Bohrmaschinen, die Vorschaltung von Umformern vorgeschlagen, die die Speisefrequenz auf ein Vielfaches der Netzfrequenz erhöhen. Diese Maßnahme diente aber in erster Linie zur Herabsetzung des Gewichtes des Motors. Die geinäll der Erfindung in hombinationeil angewendeten Maßnahmen sind bei Stampf- und Rüttelmaschinen neu und besonders vor- teilhaft. Der Umformer oder im zweiten Fall dur Stromerzeuger kann in beliebiger Eiltferiitli:1 von dem Antriebsmotor und damit dem Ger'" aufgestellt werden, da auch das Zuleite ' kabel zum Gerät die Vorteile der Erfin ::ie genießt. Damit wird der Bedieilungsperso9''_i ., einem verhältnismäßig grol'@eii ArbeitsrAg geie Bewegiiti-sinöglielil:eit in für Elektro- geräte ungünstigen Verhältnissen bei größt- möglicher Sicherheit geschalten, und es kann gleichzeitig leicht die notwendige holte Rüt- telfrequenz erreicht werden. It has also been proposed in portable power tools, such as grinding and drilling machines, the upstream connection of converters that increase the supply frequency to a multiple of the mains frequency. This measure primarily served to reduce the weight of the engine. The whole of the invention in combination applied measures are for ramming and vibrating machines are new and especially partaking. The converter or, in the second case, major The generator can be operated at any rate: 1 from the drive motor and thus the Ger '" be set up, since the supply line ' cable to the device the advantages of the invention enjoy. This means that the operator will be 9 '' _ i ., a relatively large @ eii ArbeitsrAg geie moviiti-sinöglielil: ever in for electrical equipment in unfavorable conditions with the greatest possible security switched, and it can at the same time easily got the necessary Rüt- telfrequency can be reached.
