Definitions

  • the present invention relates to a quick-change coupling for attachment of work tools to a tool carrier of a digger boom, with a device for automatically connecting power lines, in particular hydraulic lines, wherein the quick-change coupling for connecting the tool carrier with the coupling element of the Arteitswerkzeugs a hook connection and a locking unit with one of an actuator actuated, displaceable locking element identifies, wherein on the tool carrier supply fittings and the corresponding Abilleran gleich publishede the coupling element of the working tool are fixed on a support, and wherein the lock connection is closed, the Ab recruitingan gleich publishede connected to the corresponding supply terminals, and are solved with open lock unit from the supply connection pieces.
  • Newer clutch systems try to avoid these disadvantages by integrating not only the quick-change coupling for the tool on the tool carrier but also its own automatic clutch for the hydraulic connections.
  • the supply fittings on the tool carrier are held on a common support structure, such as in the form of a plate, and are in a retracted and protected position when no tool (or a tool without hydraulics) is connected. If a tool with hydraulics to be connected to this system, then the plate is moved out of its retracted position after coupling the tool with its own setting unit, and pressed against corresponding arranged on the tool pick-up fittings so that the connection is made.
  • a quick-change coupling in which the supply fittings are moved on the tool carrier when locking the quick-change coupling with the locking unit, and thereby engage with the pick-up fittings which are fixedly mounted on the coupling element of the tool.
  • the hydraulic connections are located inside the quick-change coupling, between the tool carrier and the tool, so that the space available for the fittings is very limited. Even if, as is the case in the above-mentioned document, only two hydraulic connections are provided, a compact design of the quick-change coupling are set narrow limits when using this system.
  • the supply hydraulic fittings are also actuated by the lockout unit when tools without hydraulics are used. This leads to a fast soiling and wear of the fittings.
  • the EP 1 813 730 A2 discloses a coupling for a loading blade on a liftable rocker of a front loader, wherein a hydraulic clutch is provided, of which one coupling half is pivotally mounted about a fixed horizontal axis on one of the components and the other coupling half to one along a guide track slidable horizontal axis is mounted on the other component.
  • the guideway is designed so that a Zusamanenation the two coupling halves is tangential to the pivot axis of the two coupling halves. This requires a precise interaction of all parts that are movable relative to one another.
  • the present invention overcomes the above drawbacks of the prior art by movably supporting the carrier on the coupling member of the work implement between a forward and a retracted position, the carrier comprising a follower for engagement with an operating member coupled to the slidable latch member and wherein the direction of movement of the carrier corresponds to that of the locking element.
  • the actuator When swinging the quick-change coupling thus the actuator is connected via the locking element, the actuator and the driver element with the carrier and pulls it automatically when locking the locking unit in a position in which the connections are made.
  • a more compact dimensioning of the tool carrier is possible because the moving parts of the hydraulic coupling are not on the tool carrier but on the coupling element of the tool.
  • supply fittings that are fixedly mounted on the tool carrier can be covered very easily (eg with a protective cap) and are therefore optimally protected against wear, dirt and damage if the excavator is used over a long period without tools having a hydraulic function.
  • the need to supply or secure protruding or hanging hydraulic hoses when using hydraulic-free tool is eliminated. Even a frequent change between tools with and without hydraulics is made easier.
  • By the same direction of movement of the locking element and the carrier a controlled movement is achieved both in terms of the joining of the two power lines as well as the release thereof.
  • the carrier can be mounted with play in relation to the coupling element of the working tool.
  • position tolerances are compensated, which may exist due to contamination or wear between the tool carrier and the tool, since the carrier can automatically adjust when closing the hydraulic coupling to the location of the supply hydraulic connectors on the tool carrier.
  • the carrier may have a substantially plate-shaped base, which along a provided on the coupling element of the working tool linear guide, preferably along guide rails, movable and optionally can be set up with alignment pins.
  • the fittings are easy to install, remove, clean and maintain in this way.
  • the guide rails, on which the carrier is guided linearly, allow a substantially parallel displacement of the carrier even with a play-bearing.
  • the carrier may have a substantially plate-shaped base, which is pivotally mounted for connecting or disconnecting the connecting pieces on the coupling element of the working tool.
  • the space requirement for the carrier can be further reduced.
  • a locking device for holding the carrier in its slaughterbewegten position with uncoupled working tool.
  • the actuating element may have a T-slot, wherein the driving piece may be designed as a T-head matching the T-slot.
  • a T-slot connection is particularly insusceptible to tolerances due to tolerances, and allows a self-sliding adjustment of the T-slot coupling, such as when the tool carrier moves with respect to the tool during the locking process.
  • the driver piece on the carrier with respect to the distance of the T-head can be adjustably mounted by the carrier.
  • a further preferred embodiment of the invention provides that the locking element of the locking unit is designed as a transverse bar flattened in a wedge-shaped manner at least in the region of its ends, to which the actuating unit is attached centrally, wherein the wedge tip (s) runs (runs) parallel to the longitudinal axis of the transverse bar. and is oriented toward the actuator unit, wherein the actuator is secured to the wedge back centrally of the cross bar, and wherein the supply terminals of the tool carrier are arranged above the wedge midplane and behind the wedge back.
  • the advantage of this embodiment is that the supply connectors are arranged on the tool carrier in a protected position, and thereby also do not hinder the coupling of tools that do not have their own hydraulic connectors.

It is therefore also possible to provide the guide of the carrier 11 on the one hand, and the T-slot connection between the driver 12 and the actuator 13 on the other hand with a considerable play, since the carrier 11 is adjusted by the alignment bolt 8 and thereby, as As stated above, the customer connection pieces 9 automatically aligns with the supply connection pieces 6 located in the end plate 24.
  • the pulling direction of the actuating element 13 does not have to coincide exactly with the direction of movement of the carrier 11, since the T-head of the driving piece 12 can slide in the T-slot 28 due to the low tensile force and thereby compensate for positional tolerances.
  • the actuator 13 When opening the locking unit 4, the actuator 13 exerts pressure on the head of the driver 12, so that the carrier 11 is pushed back to the starting position. As a result, the customer connection pieces 9 are pulled out completely from the supply connection pieces 6 before the wedge bar 5 is pushed back over the end of the wedge contact surface 16 and the tool carrier 1 for releasing the quick-change coupling about the pivot axis of the hook connection 3, 3 'from the connection with the working tool. 2 can be folded out.
