Abstract
Mit einer Vorrichtung zum Kuppeln und Entkuppeln der Anschlußenden von Druckmittelleitungen, insbesondere von Hydraulikleitungen, mit einer ortsfesten und einer auf einem beweglichen Schlitten bewegbaren Kupplungshälfte, die in Kuppel- und/oder Entkuppelstellung bewegbar ist, insbesondere an Werkzeugschnellwechseleinrichtungen von Bau- oder Landmaschinen, soll eine Sicherung der Kupplungshälften im gekuppelten Zustand gewährleistet werden, wobei Großserien-Leitungskupplungen einsetzbar sind, so daß die Vorrichtung leicht bedienbar und kostengünstig herstellbar sowie robust und verschleißarm ist.With a device for coupling and uncoupling the terminal ends of pressure medium lines, in particular hydraulic lines, with a stationary and movable on a movable carriage coupling half, which is movable in dome and / or Entkuppelstellung, especially on quick-change tooling of construction or agricultural machinery, should a Securing the coupling halves are ensured in the coupled state, with high-volume line couplings are used, so that the device is easy to use and inexpensive to manufacture and robust and low-wear.
Dies wird dadurch erreicht, daß der Schlitten (112) durch eine Kolben-/Zylindereinheit (113,114) bewegbar und in der Kupplungsstellung durch den Druckkolben (114), dessen Druck durch ein entsperrbares Druckhalteventil (119) gehalten ist, in der Verriegelungsstellung fixierbar ist. This is achieved in that the carriage (112) by a piston / cylinder unit (113,114) movable and in the coupling position by the pressure piston (114), the pressure of which is held by a releasable pressure holding valve (119), in the locked position.
