Definitions

  • the invention relates to quick couplers for connecting tools Machines with simultaneous connection of hydraulic lines.
  • the invention is based on the object Hydraulic coupling elements in the locking parts of the quick coupler to integrate, and thus a secure, protected and centered at the same time Ensure coupling of work equipment and hydraulic lines.
  • the Locking parts thus form an external protection against dirt and Damage to the hydraulic coupling elements and lead to a correctly positioned merging of them in the course of the Locking way.
  • One or more can be per locking part Hydraulic couplings and lines can be integrated.
  • the quick changer can have one or more locking parts. The shape and the Any location for the locking parts in the quick coupler.
  • the hydraulic coupling elements of the quick coupler and the attachments can be fixed, elastic or spring loaded.
  • the hydraulic clutch elements correspond to usual matching male / female Clutch parts.
  • the quick coupler 1 shown for loading machines is through cylinder 4 hydraulically lockable, but it can also be mechanically or be operated electromagnetically.
  • an implement e.g. a High tip bucket to be picked up with the quick coupler 1 one grabs the hook 15 of the upper quick coupler holder 3 Bucket holder 2.
  • the parts brought to the system are then locked by the hydraulic cylinder 4 by the First move the locking bolt 5 into the locking openings 13.
  • the way of the locking bolts 5 is limited by the stop 39.
  • the counter-coupling member 25 is with Spring force 26 constantly pressed against the locking bolt 5, so that too an occurring movement between attachment and quick coupler is balanced.
  • the counter-coupling elements can also without Spring-loaded, fixed or flexible storage. The hydraulic connection is therefore securely closed. Due to the internal construction of the Hydraulic coupling elements minimize the risk of external damage and ensures a centered moving together. As a rule, an inlet 17 and an outlet 16 are sufficient for a loader a hydraulic work function of the attachment. However, it can also Locking parts (Fig.6, Fig.7) used with multiple couplings to enable multiple hydraulic work functions. It can also use multiple locking parts with single couplings become.
  • the invention is for excavator quick couplers in FIGS. 4 and 5 presented in a self-explanatory manner.
