Abstract
Vorrichtung zum Sichern der Rotor- und Statorseite von Drehverbindungen bei Versagen und/oder Bruch, wobei dass die Vorrichtung an der Rotor- und Statorseite ein Profil hat, welches formschlüssig Rotor- und Statorseite axial und gegen Kippen festhält, wenn sich Rotor- und/oder Stator voneinander entfernen.Device for securing the rotor and stator side of rotary joints in case of failure and / or breakage, wherein the device on the rotor and stator side has a profile which positively holds rotor and stator side axially and against tilting when rotor and / or Remove the stator from each other.
Description
Vorrichtung zum Sichern der Rotor- und Statorseite von Drehverbindungen bei Versagen und/oder Bruch, wobei die Vorrichtung an der Rotor- und Statorseite ein Profil besitzt, welches formschlüssig Rotor- und Statorseite axial und gegen Kippen fixiert, wenn sich Rotor- und/oder Stator voneinander entfernen.Device for securing the rotor and stator side of rotary joints in case of failure and / or breakage, wherein the device on the rotor and stator side has a profile which positively locking rotor and stator side axially and against tilting when rotor and / or stator remove each other.
Bei mobilen Arbeitsmaschinen, besonders bei Hydraulikbaggern, Drehbohrgeräten, Raupenkranen oder sonstigen Maschinen ist der Aufbau so, dass sich der Unterwagen welcher meistens verfahrbar ist und der Oberwagen meistens endlos drehen können. Der Unterwagen besteht meistens aus zwei Kettenfahrschiffen (
Die erfindungsgemäße Vorrichtung ist notwendig aus dem Bedarf, dass immer mehr ungeeignete Hydraulikbagger, sprich mobile Arbeitsmaschinen mit Erdbauausleger, umgebaut werden. Dies geschieht teilweise nicht vom Hersteller, der für die Haltbarkeit der Maschine und Komponenten garantieren kann, sondern durch Händler oder Sondermaschinenbaubetrieben, die eine Standardmaschine erweitern. Durch diese Erweiterungen, zum Beispiel für eine lange Abbruchausrüstung, wird die Standardmaschine deutlich mehr belastet, als der Hersteller für den Standardbetrieb vorgesehen hat. Ein Schaden im Auslegerbereich, besonders wenn dieser nah am Arbeitswerkzeug ist, ist meistens wenig gefährlich, da im Bereich des Werkzeugs normalerweise abgebrochen wird und Material vom Gebäude herunterfällt. Wenn jedoch die Verbindung zwischen Ober- und Unterwagen einen Schaden erfährt, kann die gesamte Maschine umkippen, dies findet in der Praxis teilweise regelmäßig statt. Dies kann von Schäden an der Maschine bis hin zu Todesfällen reichen, wenn zum Beispiel ein Bagger mit langer Abbruchausrüstung in der Nähe einer Straße umkippt und dort beim Umkippen Passanten trifft. Die erfindungsgemäße Vorrichtung soll dem Betreiber der umgebauten Maschinen, der aus wirtschaftlichen Gründen, keine andere Maschine anschaffen kann, die Möglichkeit geben die Maschine abzusichern. Wenn die Drehverbindung zum Beispiel an der Kugelbahn (
Die erfindungsgemäße Vorrichtung wir auf dem Unterwagen (
Zum bessere Verständnis wird die Erfindung nachfolgend anhand 3 Figuren mit einer sinnbildlichen Beispielzeichnung, welche an jedem Unterwagen einer mobilen Arbeitsmaschine verwendbar ist, näher erläutert. Es zeigen die:For better understanding, the invention will be explained in more detail below with reference to three figures with a symbolic example drawing, which can be used on any undercarriage of a mobile work machine.
