Definitions

  • the invention relates to a quick changer according to the preamble of claim 1.
  • the invention also relates to a quick changer system with such a quick changer and an associated adapter.
  • Such quick couplers are used for simple and convenient changing of different attachments on construction machines.
  • a quick coupler e.g. swivel spoons, grippers, scissors, compressors, magnets, hydraulic hammers or other attachments can be coupled or uncoupled from a driver's cab, e.g. to a boom of an excavator, in a few seconds and with a high level of safety.
  • a generic quick coupler is known.
  • This contains a carrier which has first receptacles on one side for holding a first coupling element provided on an attachment and on the other side second receptacles with a locking element movable between a release position and a locking position for releasably holding a second coupling element.
  • the locking element is designed as a linearly movable hook slide that can be moved between an open and a closed position.
  • a display rod is attached to the hook slide, which is drawn into a housing in the closed position of the hook slide and protrudes with respect to the housing in the open position of the hook slide.
  • WO 2016/153360 A1 a visible display element for a quick hitch known.

  • the mechanical display device has a device for displaying a lack of engagement of the second coupling element on the second receptacles. Correct locking is therefore only indicated when the second coupling element is also in its position provided for correct locking. For the monitoring and display of a proper locking, not only the position of the at least one locking element but also the position of the second coupling element is included. This can improve control and increase security.
  • the device for displaying the lack of engagement of the second coupling element on the second receptacles comprises a display element movable between a locking position and an unlocking position and a coupling gear for moving the display element into the locking position when the at least one locking element is moved into the coupling position and for moving the display element backwards in the unlocking position in the event of a movement of the at least one locking element beyond the coupling position.
  • the coupling gear contains a control lever which can be pivoted about a joint on the carrier and which is connected to the display element via a joint rod and a linearly movable rod.
  • the control lever points preferably a control cam and a recess.
  • the linearly movable rod is expediently guided displaceably in a guide and is resiliently pretensioned.
  • the control lever can be rotatable by a cylinder for displacing the at least one locking element via an actuating device.
  • the actuating device can be a lever with a ball bearing.
  • the display element can be a flap which is pivotably arranged on a housing and which can be moved between a raised locking position and a lowered unlocking position via a linearly displaceable rod.
  • the display element can, however, also be a bolt that can be moved between an extended and retracted position or another suitable display element.
  • the coupling mechanism can contain a slide which can be displaced at right angles to the display element and is connected to it via a toothed drive, and an actuating element which is detachably connected to the slide.
  • the slide can be detachably connected to the actuating element, for example via a pivotable control lever.
