  • This tool change is time-consuming and always involves two Operator ahead, namely the operator, the boom arm in the appropriate position to the tool, and a second operator who uses the connecting bolts.
  • AU-B-633 242 is a generic device known, in which a front jaw and a rear Recording slot are provided, the opening down is directed while the mouth open to the front is. Furthermore, this device is slidable Sled with a locking hook available, the Opening is directed towards the rear. To connect one The front connecting bolt is now in the tool attached to the front opening mouth, then the rear connecting pin in the open Inserted slot and there with the locking hook of the sled locked.
  • the object of the invention is a propose generic device that a play-free Guaranteed fit of the tool to be picked up.
  • the clamping screw acts as a real clamping element, since this the connecting bolt to be tensioned between the lower one Leg of the U-shaped mounting mouth and the side wall wedged itself as the top clamping surface, with the amazing Result that such a reversal of the power flow in the mobile Mouth in the side wall can no longer take place and thus game is excluded.
  • the Back pressure plate firmly in the receiving and Fastening device arranged.
  • the counter pressure plate designed as a pivoting locking plate in the release position.
  • the slidable mouth with the Piston rod of a hydraulically operated cylinder connected.
  • the movable jaw is advantageous connected in such a way with a prestressed spring that the Jaw by the force of the preloaded spring in Release position is moved.
  • FIGS. 2 and 3 show, one according to the invention Recording and fastening device 2 at a distance parallel mutually standing receiving tabs 1 and 2 have opposite through openings 3.
  • Through openings 3 are in a known manner Connecting bolts can be used, the assigned recesses reach through an excavator arm, not shown, so that the mounting and fastening device with the excavator arm connected is.
  • the recording and Fastening device with a front receiving mouth 4 essentially U-shaped cross section and a rear Receiving mouth 5 with a substantially U-shaped Cross section, the openings of the two receiving mouths 4 and 5 are directed in opposite directions.
  • the rear Receiving mouth 5 an arm 6, which in a guide 7 Recording and fastening device slidably held is.
  • FIG. 4 further shows, there is a recess 8 in the arm 6 arranged with an internal thread in which a clamping screw 9 is held screwable.
  • the clamping screw 9 is rotatable held in a locking plate 10, which in turn is pivotable is, like this the double arrow designated 11 in FIG. 5 displays.
  • FIGS. 1 and 2 show, that is sliding rear mouth 5 with the piston rod 12 one hydraulically actuated pressure cylinder 13 connected.
  • the movable mouth 5 is so with a biased Spring 14 connected that it is biased by the force of Spring is moved to the release position.
  • a Excavator bucket 15 also two at a distance and parallel mutually extending receiving tabs 16, each with two opposite openings in the Connection bolts 17 are used in a known manner.
  • the clamping screw 9 When using the recording and Fastening device, the clamping screw 9 is loosened and the locking plate 10 pivoted to the left in which it can slide between the guides 7, as shown in Fig. 5th is shown.
  • the biased spring 14 that slidable receiving mouth 5 in the direction of the front Recording mouth 4 moved to the release position. Subsequently the cradle with the front jaw 4 in the front connecting bolt 17 of the excavator bucket 15 hooked, as shown in Fig. 1.
  • the locking plate 10 is after right by 90 ° in the position shown in Figs. 4 and 5 pivoted, in which it rests on the guides 7.
  • the clamping screw 9 By Tightening the clamping screw 9 is a secure connection guaranteed.
  • the receiving and Fastening device also with tools different distance between the connecting bolts 17th applicable.
  • the receiving mouths 4, 5 are themselves widened towards its opening in a wedge shape. This means that a safe, backlash-free fit is guaranteed because the locating bolts jam in the receiving mouths.
  • FIG. 2 further shows that the receiving mouth 5 at an angle of approx. 15 ° to the connecting line of the Muzzle 4 and 5 inclined downwards the receiving and fastening device is arranged.
  • the Hydraulic cylinder further up in the intake and Fastening device may be arranged so that between a free space is created for the reception mouths. This makes possible the inclusion of tools between the Studs hump or the like. have, as shown in FIG. 2 shows.
  • the aim of this invention is to address this recognized disadvantage eliminate and develop a quick change device which is a quick change for marketable unchanged Tools.
  • the usual tools on the market are in the Usually two hinge pins between two side plates as Articulation points for a quick-change device for Available. Usually extends between the Hinge pin is a stiffening plate with its highest Survey on the direct connecting line of the Hinge pin centers protrudes.
  • the Hinge pin diameters and positions can be found in the the usual tools available on the market Areas fluctuate, and are also subject to the same Types not inconsiderable fluctuations.
  • these boundary conditions are elegant Execution and arrangement of the components of the Quick-change device is taken into account and lead to a solution that is amazing for a very large Number of common tools can be used.
  • the mouth can be wedge-shaped, different Bolt diameters are gripped, the bolts not strike the back of the mouth by one To achieve adjustment effect in the event of pin wear.
  • the special embodiment of the mouth causes that in Operation of soil cultivation tools when inserting the quick-change device on the Bolts can dodge into the corners of the mouth and one Mismatch is prevented by the effect of dirt.
  • the movable mouth that acts on the second hinge pin is designed according to the invention so that the actuating means, Hydraulic cylinder with return spring and tension screw in are inclined so that the usual Reinforcement plates on the tools between the Pivot pins are not an obstacle when coupling.
  • the thread of the clamping screw is through a shaft seal protected against external influences.
  • the movable mouth is wedge-shaped designs and clamps the hinge pin between the wedge and Housing.
  • the orientation of the actuating means was changed According to the invention chosen so that the actuating force direction acts towards the center of the bolt and still the guide arm together with the wedge from a single part consists.
  • Control element e.g. hydraulic cylinder
  • clamping screw leads to the following advantages: If the remote control fails Control element, the tool remains securely locked.
  • the quick-change device remains functional, i.e. According to the invention, tools can this arrangement continues to be solved by the device and can also be coupled again.
  • the bias spring cleverly arranged so that on the one hand the Tension screw does not buckle when opening the lock is claimed, and that on the other hand, the locking of the Tool supported by the remote control is not from the spring, because when locking due to imprecise Positioning it is necessary to use the pre-positioned tool to pull into position.
  • a remote control with Clamping screw resulting difficulty that an operator Must adjust the clamping screw by long distances, synonymous with many turns on the turnbuckle before that remote-controlled actuating element (e.g. hydraulic cylinder) can use is achieved according to the invention in that a locking plate is pivotally arranged so that one the clamping screw in and out of engagement in no time can bring to e.g. hydraulically adjustable.
  • actuating element e.g. hydraulic cylinder
  • a disc spring between the tension screw head and the locking plate additionally serves according to the invention, the clamping screw keep under tension to loosen the screw prevent and additionally serves the externally visible Spring travel of the disc spring as a visual control for the Operator, who then correctly pre-tensioned the screw, when the full spring travel of the disc spring is being used has been.
