Abstract
Description
Die Erfindung bezieht sich auf eine Vorrichtung zur mechanischen Verriegelung eines doppeltwirkenden Hydraulikzylinders in Endlagen durch eine druckfederbeaufschlagte zwischengeschaltete Schiebemuffe durch einstellbare Verriegelungskugeln zwischen Schiebemuffe und Kolbenstange.The The invention relates to a device for mechanical locking a double-acting hydraulic cylinder in end positions by a spring-loaded Interposed sliding sleeve by adjustable locking balls between sliding sleeve and piston rod.
Derartige Anordnungen zur mechanischen Verriegelung über Schiebemuffen sind grundsätzlich bekannt, um eine formschlüssige Verbindung zwischen Zylinder und Kolbenstange herzustellen. In der Praxis hat sich herausgestellt, daß die bekannten Selbstverriegelungen unter Berücksichtigung von Lasten starke Beschädigungen in den Bauteilen hervorrufen und somit nur bedingt einsatzfähig sind.such Arrangements for mechanical locking via sliding sleeves are known in principle, a form-fitting Make connection between cylinder and piston rod. In practice it turned out that the known self-locking, taking into account loads strong damage cause in the components and thus are only partially operational.
Die Aufgabe der Erfindung ist es, einfache Vorrichtungen zur Vermeidung von Überbelastungen auf einfache Weise zu schaffen und ohne zusätzliche Elektronik eine funktionsfähige Einheit zu gewährleisten.The The object of the invention is to avoid simple devices from overloading on easy way to create and without any additional electronics a functional unit to ensure.
Die Lösung dieser Aufgabe erfolgt erfindungsgemäße dadurch, daß im Zylinderendbereich ein Hydraulikanschluß über eine Steuereinheit angeordnet ist, die druckgesteuerten Steuerkolben mit Steuerstangen aufweist und die Steuerstangen auf die Schiebehülse zur Entriegelung einwirken sowie der Hydraulikanschluß mit einer Einlaßleitung sowie einer Auslaßeinleitung über jeweils ein Rückschlagventil mit dem Kolbenraum des Zylinders verbunden ist, wobei die Einlaß- oder Auslaßleitung über mindestens einen Steuerkolben entsprechend einer entriegelten oder verriegelten Position freigebbar ist.The solution This object is achieved according to the invention in that in the Zylinderendbereich a Hydraulic connection via a Control unit is arranged, the pressure-controlled control piston Having control rods and the control rods on the sliding sleeve for Unlocking act as well as the hydraulic connection with a inlet line as well as an outlet initiation over each a check valve is connected to the piston chamber of the cylinder, wherein the inlet or Outlet pipe over at least a control piston according to an unlocked or locked Position is releasable.
Hierdurch ist es möglich, auch unter Last eine gedämpfte Verriegelung vorzunehmen.hereby Is it possible, even under load a subdued Lock to make.
Ferner wird vorgeschlagen, daß die Steuerstange des Steuerkolbens für die Steuerung der Einlaß- und Auslaßleitung einen größeren Durchmesser als die Steuerstange des weiteren Steuerkolbens aufweist.Further It is suggested that the Control rod of the control piston for the control of the intake and outlet pipe a larger diameter than having the control rod of the further control piston.
Zur einfachen Handhabung und Nachrüstung wird vorgeschlagen, daß die Steuereinheit als aufsetzbares Element für den Zylinder ausgebildet ist.to easy handling and retrofitting It is suggested that the Control unit is designed as an attachable element for the cylinder.
