Abstract

The invention relates to a quick-change system for changing attachments on a construction machine. THE quick-change system for changing attachments on a construction machine includes a quick changer (1) mounted to rotate in a drive housing (4) of a rotary device (3) and rotatable relative to drive housing (4) by a rotary drive (9, 10), and a rotary joint (6) arranged in the drive housing (4) with a stator (7) and a rotor (8) rotatable within THE stator (7) to supply a working fluid to the quick changer (1). In order to permit simple and stable fastening of the rotary joint, the stator (7) of the rotary joint (6) arranged within a through-opening (30) of the drive housing (4) is radially supported against the drive housing (4) above an upper end surface (38) and beneath the upper end surface (38) of a drive wheel (10) of the rotary drive (10) arranged in the drive housing (4).

Description

technical field [0001] The invention relates to a quick-change system for replacing additional equipment on a construction machine according to the preamble of claim 1 . Background technique [0002] Such a quick-change system is known from DE 10 2013 206 574 A1 for the simple and convenient exchange of different additional devices on a construction machine. The quick change system has a quick changer which is rotatably mounted in the drive housing and can be rotated relative to the drive housing by rotating the drive, and has a swivel joint which is arranged in the drive housing and has a fastening part and a rotating part rotatable within the fixed part for feeding the working fluid to the quick changer. Additional equipment coupled to the quick changer via rotary drives, such as swing buckets, grabs, shears, compactors, magnets, hydraulic hammers, etc., are not only able to Rotate, but also can rotate around the axis of rotation orthogonal to the axis of swing. Via the...
