Definitions

  • the invention relates to an adapter according to the type specified in the preamble of claim 1 and a quick-change device according to the specified in the preamble of claim 6 Art.
  • the quick coupler is pivotally mounted on a hydraulically operated boom of the earthmoving machine about a horizontal axis and can be connected to the adapter.
  • the quick coupler has fixed, aligned in a first direction claws, two in the first direction for releasing and in a first direction opposite the second direction for locking sliding latch bolt and the claw remotely located abutment surface.
  • the adapter consists of a base plate on which at one end a latch plate and at the opposite end by means of fastening tabs a coupling lateral surface is provided.
  • the locking plate has, on the side facing the coupling lateral surface, a first clamping surface which is preferably perpendicular to a vertical surface inclined by 5 ° to 15 °.
  • the locking plate is further provided with two spaced-apart and conically shaped in cross section openings. The cone angle of limited by lateral surfaces breakthroughs is dimensioned according to the end of the locking bolt.
  • the clutch shell surfaces facing side of the latch plate forms a first clamping surface and the conical openings a second clamping surface.
  • the quick coupler comprises a limited by the claws cylinder jacket-shaped abutment surface for the purpose of support on the cylindrical coupling surface of the adapter.
  • the abutment surface of the quick coupler is flat, corresponding to the first clamping surface of the latch plate.
  • a disadvantage of this design is that when mounted on a working adapter a rotated by 180 ° mounting the implement relative to the quick coupler with the adapter is not possible.
  • the implement can always be coupled to the quick coupler only according to the installation of the adapter on the implement, as on the first side of the adapter, the claw of the quick coupler associated with the coupling surface and on the second side of the adapter the locking surface and the locking bolt associated latch plate is provided with the openings.
  • quick coupler devices which have a quick coupler having identically formed claws on each side.
  • the adapter has the cylindrical claw surfaces associated with the claws. Since all jaws are the same and only on one side of the claws for locking and unlocking are translationally reciprocated, the implement can be connected to the adapter in both rotated by 180 ° positions relative to the quick coupler with this.
  • the adapter has on a first side at least one jaw of the quick coupler associated clutch casing surface and on a second side of an abutment surface of the quick coupler associated first clamping surface and a locking bolt of the quick coupler associated second clamping surface. Both on the first and on the second page Thus, at least one of the claws associated clutch surface, one of the abutment surface associated first clamping surface and the locking bolt associated second clamping surface are provided.
  • the quick coupler is selectively connectable with its claws with respect to the first side of the adapter or with respect to the second side of the adapter aligned with the adapter.
  • the first clamping surfaces have an acute angle to each other.
  • the coupling lateral surface, the first clamping surface and the second clamping surface are arranged such that, in the locked state, a multiaxial clamping of adapter and quick coupler results.

  • the invention is based on the recognition in view of the adapter that realizes all surface shapes for the different functions when coupling and locking the quick coupler with the adapter on the first and on the second side of the adapter must be in order to enable a coupling in both rotated by 180 ° positions. It should preferably be avoided that several abutment surfaces cooperate with a common clamping surface.
  • the second clamping surface is formed by a depression in or by an increase on the bolt axis.
  • each surface has an optimized shape adapted to the conditions. Therefore, it is advantageous if the individual clamping surfaces and areas of the coupling lateral surfaces do not overlap, ie the area of the first clamping surface, the second clamping surface and the coupling lateral surfaces are different and have dedicated abutment surfaces on the quick coupler.
  • the second clamping surface is formed by a recess, for example by milling or the like in the bolt axis, or by an increase, for example by applying / fixing a plate on the bolt axis.
  • Each second clamping surface is preferably arranged in a recess or on an increase of the bolt axis.
  • at least two locking shafts are provided on each side of the adapter, each having the coupling lateral surfaces and the first and second clamping surfaces.
  • the bolt axes fulfill the function of a load-absorbing cross member.
  • both bolt axes are identical.
  • the second clamping surface is arranged in each case below the longitudinal central axis of the bolt axis.
  • centering means are provided on the adapter and / or quick coupler such that shortly before concerns of the quick coupler on the first clamping surface, the locking bolts are aligned to the second clamping surface.
  • the centering means can be formed by adjacently to the first clamping surface in the recess partially conically extending side surface areas - inlet guides -.
  • the centering means can also be formed by elevations and corresponding recesses in the quick coupler and adapter. This ensures that the locking bolts extending out of the quick coupler are precisely aligned by the centering means to the second clamping surface and the multiaxial clamping is optimized.

  • the second clamping surface is formed curved over an angle up to 180 °.
  • the bolt axis is formed symmetrically to a transverse center plane of the adapter.
  • the first and second clamping surfaces essentially form a common edge.

  • the distance between the two coaxial juxtaposed latch axes substantially corresponds to the working space and / or the field of view for an actuating means for the quick coupler - a hand-operated quick coupler - and a display means for the locking state of the quick-change device.
  • the bolt axis may be provided with a particular centrally arranged recess for an actuating means for the quick coupler, for example, to be able to comply with certain angles during operation of the actuating means.
  • the locking axle acting as a cross member may in particular be fastened laterally in tabs.
  • the tabs and the bolt axes form a torsion-resistant frame.

  • the claws are arranged so that each claw covers a recess and rests in the mounted state of the quick-change device on both sides of the associated recess. This will ensures that a stable and wide support surface is guaranteed.
  • the abutment surface of the quick coupler may be at least partially formed by a reinforcing plate.
  • the reinforcing plate is formed in particular from wear-resistant material and may be tempered.
  • the reinforcing plate is releasably connected to the quick coupler. In case of wear, this can then be easily replaced.
  • the abutment surfaces can be optimally formed according to their functions, according to one embodiment, these do not overlap in their lateral arrangement, i. the abutment surface of the quick coupler extends between the remote jaws, but not beyond. As a result, claws are over the entire surface over the entire pivot angle on the bolt axis.
  • the abutment surface is formed by an increase, whereby the area of the abutment surface can be defined exactly.
  • the quick coupler may have a mechanical and / or hydraulic drive.
  • the second clamping surface and the locking bolt of the quick coupler in the assembled state a flat contact on.
  • the second clamping surface and the corresponding region of the locking bolt of the quick coupler are formed corresponding to each other.
