Definitions

  • the invention relates to an adapter for a quick-change system according to the preamble of claim 1.
  • the invention also relates to a quick-change system with an adapter of this type.
  • Such quick-change systems are used for easy and convenient changing of different attachments on construction machines.
  • quick-change systems e.g. swivel buckets, grabs, shears, compactors, magnets, hydraulic hammers or other attachments can be coupled or uncoupled in a few seconds and with a high safety standard from a driver's cab, e.g.
  • the attachment side usually contain an adapter on the attachment side and a quick coupler arranged on the construction machine, which has, for example, jaw-shaped first receptacles on one side for retaining a first coupling element and on the other side second receptacles with at least one locking element that can be moved between a release position and a locking position for releasable retaining having a second coupling element.
  • a quick coupler arranged on the construction machine, which has, for example, jaw-shaped first receptacles on one side for retaining a first coupling element and on the other side second receptacles with at least one locking element that can be moved between a release position and a locking position for releasable retaining having a second coupling element.
  • an adapter for such a quick-change system is known. This has to connect the adapter with a quick coupler.
  • a coupling element carrier for holding adapter-side coupling elements for a coupling with quick-change coupling elements is fastened to one of the two bolt-shaped coupling elements.
  • connecting webs provided with mounting holes for screws are welded to one of the two bolt-shaped coupling elements.
  • a holder of the coupling element carrier provided with openings for the coupling elements can be screwed onto these connecting webs via holding webs welded to the holder.
  • the attachment of the connecting webs to the bolt-shaped coupling element and the attachment of the retaining webs to the bracket is done via welded joints, which is associated with a significant manufacturing effort.
  • the object of the invention is to create an adapter and a quick-change system with such an adapter that allow a simplified attachment of the coupling element carrier.
  • the coupling element carrier is connected directly to the bolt-shaped coupling element via a releasable form-fitting connection, secured against rotation, and can be releasably attached to the coupling element, e.g. using screws or other fastening elements.
  • a connection between the coupling element and the coupling element carrier that is secured against rotation and can be easily released if necessary can also be created without connection elements that can be attached to the coupling element in a complex manner. In the event of any damage to the coupling element carrier, it can therefore be easily replaced without any time-consuming alignment work.
  • the screws can be used to achieve a frictional connection between the coupling element carrier and the coupling element, while the form-fitting connection ensures exact alignment and a holder that is secured against twisting. Even if there are any changes or adjustments to the coupling element carrier, it can simply be dismantled and replaced with a correspondingly modified coupling element carrier.
  • the form-fitting connection between the coupling element carrier and the coupling element can be formed by a form-fitting contour worked into the coupling element and a corresponding counter-contour on the coupling element carrier.
  • the form-fitting contour on the coupling element can expediently be formed by a plurality of groove-shaped indentations with different contact surfaces.
  • the groove-shaped depressions can be worked into the outside of the coupling element with differently inclined contact surfaces.
  • the mating contour on the coupling element carrier that matches the form-fitting contour on the coupling element can be arranged expediently on laterally protruding fork-shaped holding webs of the coupling element carrier.
  • the holding webs can be arranged on a strip-shaped holder provided with receptacles for coupling elements.
  • the holding webs can preferably be formed in one piece with the strip-shaped holder.
  • the counter-contour can preferably be formed by differently inclined counter-surfaces on the inside of a fork-shaped recess.
  • connection between the coupling element and the side walls can be made, for example, via a positive connection with a special contour on the coupling element and a matching counter-contour on at least one side wall.
  • the coupling element carrier can be fastened to the bolt-shaped coupling element in a non-positive manner by means of screws.
  • the screws can, for example, engage in threaded holes on the coupling element carrier through transverse bores in the bolt-shaped coupling element.
  • the invention also relates to a quick-change system with an adapter described above and a quick-change device that can be coupled to the adapter for easy changing of an attachment on vehicles.
  • FIG. 1 and 2 is a quick-change system consisting of an adapter 1 and an associated quick-change device 2 for easy changing of an attachment 3, which is only partially shown, on vehicles, in particular construction machines, in a still separate position ( figure 1 ) and a coupled position ( figure 2 ) shown.
  • a quick-change system swivel buckets, grippers, shears, magnets, compactors, hydraulic hammers or other mechanical or hydraulic attachments can be easily and conveniently coupled to or decoupled from a driver's cab on a boom or other attachment of a construction vehicle.
  • the adapter 1 arranged on the attachment 3 contains two mutually parallel side walls 4 spaced apart from one another, between which a first bolt-shaped coupling element 5 and a second bolt-shaped coupling element 6 arranged at a predetermined distance therefrom are held for the detachable connection to the quick coupler 2.
  • the two parallel bolt-shaped coupling elements 5 and 6 are inserted into corresponding openings 7 and 8 in the two side panels 4 of the adapter 1 and fixed there.
  • the quick coupler 2 which can be mounted, for example, on a boom of an excavator, contains, on one side, open, fork-shaped or jaw-shaped first receptacles 9 for receiving and holding the first bolt-shaped coupling element 5, and on the other side, second receptacles 10 open downwards with a figure 2 movable locking element 11 shown for receiving and holding the second bolt-shaped Coupling element 6.
  • the receptacles 10, which are open at the bottom, have a curved contact surface 12 for contacting the second bolt-shaped coupling element 6.
  • the quick coupler 2 contains a carrier 13 which contains two fork-shaped or jaw-shaped receptacles 9 for the first coupling element 5 on one side and two receptacles 10 for the second coupling element 6 on the other side.
  • continuous receiving openings 15 for fastening bolts (not shown) for fastening the quick coupler 2 to a boom of an excavator or a connection part of another construction vehicle are provided on two parallel side parts 14 arranged on the upper side of the carrier 13 .
  • the locking elements 11, designed as locking bolts in the embodiment shown are hydraulically connected between an in figure 1 retracted release position shown and a in figure 2 shown extended locking position slidably arranged.
  • the second receptacles 10 which are open at the bottom, are closed by the bolt-shaped locking elements 11 on the underside, so that the locking element 11 reaches under the second bolt-shaped coupling element 6 and the adapter 1 can be held on the quick coupler 2.
  • the quick coupler 2 which is usually arranged on a boom of an excavator, is first moved in such a way that the first bolt-shaped coupling element 6 on the adapter 1 is moved into the jaw-shaped receptacles 10 on one side of the quick coupler 2 . Then, with the locking elements 11 still pulled back, the quick coupler 2 is pivoted about the first bolt-shaped coupling element 5 in such a way that the second bolt-shaped coupling element 6 on the adapter 1 comes to rest on the contact surfaces 12 of the receptacles 10, which are open at the bottom, on the other side of the quick coupler 2.
  • a coupling element carrier 16 for holding adapter-side coupling elements for a coupling with quick coupler-side coupling elements 2 is releasably attached to the second bolt-shaped coupling element 6 of the adapter 1 .
  • the adapter-side coupling elements (not shown) arranged on the coupling element carrier 16 can be used to automatically connect energy connections provided on the adapter 1 with corresponding energy supply lines on the quick coupler 2 to supply energy to the attachment 3 when coupling the adapter 1 to the quick coupler 2 .
  • the attachment 3 can be supplied with hydraulic fluid, electrical energy or another energy source, for example.
  • the coupling element carrier 16 has a strip-shaped holder 18 , which is provided with hole-shaped receptacles 17 for coupling elements and is arranged parallel to the coupling element 6 , with holding webs 19 and 20 arranged thereon for the detachable connection to the bolt-shaped coupling element 6 .
  • two forked outer holding webs 19 and a forked inner holding web 20 are arranged on the strip-shaped holder 18 .
  • the coupling element carrier 16 is non-positively fastened to the coupling element 6 by means of screws 21 via the fork-shaped holding webs 19 and 20 that overlap the coupling element 6 .
  • the screws 21 engage in threaded bores 23 of the holding webs 19 and 20 through transverse bores 22 in the coupling element.
  • the coupling element 6 has opposite flattened areas 24 on at least one end for engagement with corresponding mating surfaces 25 on the corresponding opening 8 in the side wall 4 .
  • the bolt-shaped coupling element 6 has an incorporated positive-locking contour 26 on its outside for positive-locking engagement with a corresponding counter-contour 27 on the fork-shaped retaining webs 19 and 20 of the coupling element carrier 16 that protrude in relation to the holder 18 .
  • the form-fitting contour 26, designed as an outer contour with indentations, on the coupling element 6 is also figure 3 recognizable groove-shaped depressions 28, 29 and 30 formed, which are incorporated at different angles in the outside of the bolt-shaped coupling element 6 and different inclined contact surfaces 31, 32 and 33 for contact with corresponding mating surfaces 34, 35 and 36 of the coupling element carrier 16 form.
  • the mating surfaces 34, 35 and 36 are provided on the inside of a fork-shaped recess 37 on the laterally projecting holding webs 19 and 20 of the coupling element carrier 16.
