If the bolt 28 is assembled by the bolt drive 42, as shown in FIGS. 5A and 5B, the side cheeks 46 of the tool parts 22, 23 are pivotally mounted on the outer bolt parts 28b. When the outer pin members 28b are separated by the pin driver 42 in opposite directions from the central pin member 28a (see FIGS. 6A-C), the side cheeks 46 of the tool members 22, 23 may be transverse (ie, downward, for example) to the longitudinal axis of the pin 28 in Fig. 6A) are released from the hinge 26 of the attachment 14.
- the outer pin parts 28b are preferably biased by the pin drive 42 into their positions connected to the middle pin part 28a.

- These side cheeks 48 are preferably formed integrally with the side cheeks 46, which have the through openings for the outer bolt parts 28b.
- the lifting cylinders 30, 31 each have a substantially rod-shaped first engagement element 36a.
- the rod-shaped first engagement elements 36a can be moved in the direction transverse to their longitudinal axis out of the hook-shaped second engagement elements 36b on the side cheeks 48 of the tool parts.
- the second linkages 36 are not limited to this embodiment only.
- the first engagement elements 36a may be formed on the lift cylinders 30, 31 as well as pin-shaped engagement elements, which are displaceable in the direction of its longitudinal axis.
- the second engagement elements 36b are formed as cylindrical engagement elements, for example in the form of passage openings in the side cheeks 48 of the tool parts 22, 23.
- the release of the connection of such a second articulation device 36 can, for example, take place in parallel with the release of the articulated connection, in that the pin drive 42 simultaneously moves the pin-shaped first engagement elements 36a of the second articulation devices 36.
- the construction of the second articulation devices 36 can also be carried out in a respectively reverse construction of the first and second engagement elements. That that, for example, the first engagement elements 36a on the lifting cylinders 30, 31 hook-shaped and the second engagement elements 36b on the side walls 48 of the tool parts 22, 23 may be configured rod-shaped.
- the bolt drive 42 is formed by hydraulic drive elements.
- the bolt drive 42 is also connected to the hydraulic supply lines of the attachment drive.
- a switching element eg manually or remotely controlled, not shown
- a rotary drive of the attachment 14 during a tool change is not required, can be dispensed with additional supply lines for the bolt drive 42.
- electromotive drive elements for the bolt drive 42 such switching is not necessary.
- 7A initially shows the initial state of the attachment 14, in which the tool parts 22, 23 are fastened to the frame 16 and the tool drive 20, so that the attachment 14 is ready for use.
- the outer bolt parts 28b are now pulled out of the joint 26 by means of the bolt drive 42 (see Fig. 7B), after possibly the drive supply lines have been switched accordingly. If the two outer bolt parts 28b are pulled out to the maximum, the side cheeks 46 of the tool parts 22, 23 can be removed from the joint 26. As shown in Fig. 7C, this is done by the piston rods of the lifting cylinders 30, 31 are extended and thus the frame 16 is pulled away from the tool 18.
- the second linkage means 36 are connected via rigidly formed levers 38, 40 to the central hinge 26 on the frame 16 and the first and second engagement elements 36a, 36b of the second linkage means 36 upon release of the tool 18 by means of the lifting cylinder 30th , 31 of the tool drive 20 are separated from each other.
- the levers 38, 40 may be designed to guide the movement of the second articulation means 36 relative to the hinge 26 as a length-adjustable lever.
- the drive for length change of these length-adjustable lever for example, hydraulic and / or electromotive drive elements have.
- hydraulic drive elements these can be used parallel to the Supply of the bolt drive 42 are switched to the hydraulic supply lines of the attachment drive.
- these length-adjustable lever When operating the attachment 14 with coupled tool 18, these length-adjustable lever must have a predetermined fixed length, so that an actuation of the lifting cylinder 30, 31 leads to a pivoting of the tool parts 22, 23 about the hinge 26.
- the first and second engagement elements 36a, 36b of the second Anlenkein- devices 36 can then be solved by means of a change in length of the length-adjustable lever from each other.
- the length-adjustable lever can also a game between the first and second engagement elements 36a, 36b of the second link 36, which can arise over time, be compensated. As a result, the secure attachment of the tool 20 to the tool drive 20 is permanently ensured.
