Quick change system for replacing additional equipment on engineering machinery
The invention relates to a quick-change system for changing additional equipment on a construction machine, comprising a quick-change device which is arranged on a connecting part (2) so as to be rotatable about a rotational axis by means of a hydraulic rotary drive (9) and to be rotatable about a pivot axis orthogonal to the rotational axis by means of a hydraulic pivot drive (12), the quick changer comprises a receptacle and at least one locking element which can be actuated by means of a hydraulic drive (27) for holding an additional device (46) coupled to the quick changer (1). The quick change system is characterized in that it comprises a hydraulic control device (44) comprising: a first control circuit (47) for actuating the rotary drive (9) and the pivot drive (12); at least one further control circuit (61) for supplying an additional device (46) coupled to the quick changer (1); and a shuttle valve device (64) for applying a higher pressure acting in the first or at least one further control circuit (47, 61) to the hydraulic drive (27) in order to actuate the at least one locking element (26).
本发明涉及一种用于更换工程机械上的附加设备的快换系统，具有一布置为在连接部件(2)上借助于液压转动驱动器(9)可绕转动轴线转动的且借助于液压枢转驱动器(12)可围绕与转动轴线正交的枢转轴线转动的快速更换器，该快速更换器包括接纳部以及至少一个借助于液压驱动器(27)能致动的锁定元件以用于保持耦联在快速更换器(1)上的附加设备(46)。该快换系统的特征在于包括一液压控制装置(44)，该液压控制装置包括：用于驱控转动驱动器(9)和枢转驱动器(12)的第一控制回路(47)；用于给耦联在快速更换器(1)上的附加设备(46)供给的至少一个另外的控制回路(61)；以及一梭阀装置(64)，用于向液压驱动器(27)加载在第一或至少一个另外的控制回路(47、61)中起作用的较高的压力以致动至少一个锁定元件(26)。
