Definitions

  • the present invention relates to a quick coupler for coupling a tool such as buckets, claw grippers or demolition tongs to a tool guide such as excavator handle or the like, with a Ankuppelability for receiving a first locking member and a locking receptacle for receiving a second locking member, wherein the Ankuppelage a preferably self-locking securing element for Catching and / or securing the first locking part is assigned in the Ankuppelage and the locking receptacle is associated with a pressure-medium-actuated locking element for locking the second locking part in the locking receptacle.
  • quick couplers are often used to couple various tools such as tedding spoons, claw grabs or demolition tongs to a digger handle or similar tool guides such as articulated arm jibs to use various tools without long changeover times.

  • the two coupling parts can be pivoted to each other, wherein the seated in the Ankuppelage locking axis forms the axis of rotation, so that the second locking axis retracts into the locking receptacle or is pivoted into, where said second locking axis then by a locking element such as an extendable wedge can be locked, so that at the same time it is no longer possible to move the first locking axle from the Ankuppelage.
  • a locking element such as an extendable wedge
  • the said locking axes on the one coupling part can thereby be formed by locking bolts, which may extend in particular parallel to each other on the corresponding coupling part, but instead of such bolts but possibly other structural parts of the coupling part such as projecting lugs, stub axles, engagement stumps in the form of projections or Recesses, for example in the form of pockets can serve as a locking part, which are adapted to the Ankuppelage or the locking receptacle of the other coupling part.
  • this fuse element When dismantling a tool after unlocking the locking receptacle and the first locking axle from the Ankuppelage drive out or unhook, this fuse element must be released or spent in its releasing position. This can be done with fluid pressure, for example, by a single-acting pressure cylinder, which can drive the fuse element against its spring bias in the locking or blocking position back to the releasing position. As a result, a dismount of the machine operator or a manual actuation can be avoided.
  • the unlocking or releasing of said Secured element on the Ankuppelage accomplished by a separate pressure medium circuit, which is independent of the pressure medium circuit for actuating the locking mechanism controllable or separately formed thereof.
  • This decoupling is done to prevent interference on the fuse element can not affect the actual locking mechanism and can cause unintentional release of the coupler lock during operation.
  • Such disturbances could be, for example, pressure losses on, for example, sealing elements which are provided in pressure circuit sections leading to the securing element of the coupling receptacle.

  • upstream is meant that said switching valve is disposed between a pressure source or a pressure source port and the pressure reducing valve so that pressure coming from the pressure source or pressure fluid coming from the pressure source first flows through the switching valve before reaching the pressure reducing valve becomes.
  • the valve means on the output side of said pressure reducing valve comprise a directional or switching valve, in a first switching position from the Pressure Reducing Valve conducts reduced pressure to the interlocking pressure port and, in a second switching position, directs the pressure reduced by the pressure reducing valve to the unlocking pressure port.
  • a further pressure reducing valve can be assigned to the locking pressure connection so that the pressure already reduced by the aforementioned first pressure reducing valve is reduced again and locking of the locking element of the locking receptacle takes place at a lower pressure than the unlocking.

  • a pressure reducing valve 28 is provided in the leading to the locking pressure port 17 line so that the pressure used for locking is lower than the pressure used for unlocking.
  • the said pressure reducing valve 28 is advantageously provided with a bypass 31 which is connected to a check valve 32 in order to avoid the resistance of the pressure reducing valve 28 when unlocking.
  • the provided for actuating the securing element 7 Stellaktor 8 is connected via a pressure switching valve 19 to the unlocking pressure port 16, said pressure switching valve 19 is designed such that the securing element 7 is shut off at the intended for unlocking the locking element 11 pressure from the rest of the pressure circuit , ie the pressure switching valve 19 opens only at a pressure p1, which is above the normal unlocking pressure for unlocking the locking element 11.
  • the valve device 18 comprises a corresponding pressure control device 20, according to the drawn embodiment according to Fig.
  • a pressure reducing valve 21 and a pressure reducing valve 21 upstream of the switching or switching valve or secondary switching valve 22 may include.
  • Said pressure reducing valve 21 and the secondary switching valve 22 upstream therefrom are advantageously preceded by the primary switching valve 23 described above, so that pressure coming from the pressure source P first reaches the secondary switching valve 22 and then the pressure reducing valve 21 before the first from the pressure reducing valve 21 reduced pressure then passes to the primary switching valve 23.
  • the pressure switching valve 19 is designed and adjusted such that the switching pressure is smaller than said input pressure p2, so that in this case, the pressure switching valve 19 opens and the pressure on the fuse element 7 and its Stellaktor 8 is given, whereby the Ankuppelage. 6 is unlocked.
  • a check valve 24 is provided, which is provided between the secondary switching valve 22 and the unlocking pressure port 16 in the bypass line to the pressure reducing valve 21 around.
  • This check valve 24 prevents upon actuation of the primary switching valve 23 for unlocking the locking receptacle 10 an unwanted pressure loss on the still un-actuated secondary switching valve 22 toward the tank T.
  • Another check valve is provided in the other connection line between the secondary switching valve 22 and the primary switching valve 23 to prevent the switching state for unlocking the securing element 7, ie for actuating the actuator 8, the pressure given to the unlocking pressure port 16 unintentionally flows back over the then open to the tank primary switching valve 23.
  • the full system pressure p2 is passed over the then switched on switching valve 22 on the pressure reducing valve 21 on said unlocking pressure port 16, while on the other hand, the primary switching valve 23 is switched to the unlocked position, so that the fully switched system pressure p2, so to speak backwards over the primary switching valve 23 and the pressure reducing valve 21 could flow to the tank, but this is prevented by the check valve 40.
  • Said check valve 40 may in this case be provided upstream or downstream of said pressure reducing valve 21 between the two switching valves 23 and 22.
  • FIG. 4 further shows, further check valves 25 and 26 are provided in relief lines that connect the Stellaktor 8 of the fuse element 7, bypassing the aforementioned pressure switching valve 19 with the unlocking pressure port 16 and the locking pressure port 17 and thus depending on the switching position of the main valve block with the tank, to allow a reflux of the pressed into the Stellaktor 8 fluid.
  • the said relief lines 33 and 34 are connected to a respective check valve 25 and 26, which check valves allow only a backflow of hydraulic fluid, but no actuation of the Stellaktors 8 forth from the pressurized pressure ports ago.
  • said relief lines 33 and 34 are provided with a flow obstruction 27 in the form of a diaphragm, see. Fig. 4 ,
  • the leading to the lock line relief line 33 here allows the relaxation of the hydraulic pressure in Stellaktor 8 of the fuse element 7, as soon as the secondary switching valve 22 is brought back into the starting position and thus the safety device of Ankuppelage 6 should be activated again, i. should be reset by the spring 9 again.
  • This will, so to speak, lock in the pressure at that location, i. prevents the area of Stellaktors 8 when the pressure switching valve 19 closes due to falling below the switching pressure in the unlocking again.
  • the switching pressure in the unlocking line or the unlocking pressure connection 16 is still initially present, so that it would not be possible to relieve this pressure without closing the pressure switching valve 19 in this way. In this case, however, the pressure above the lock-pressure port 17 and the still-actuated primary switching valve 23 can be reduced to the tank T.
  • the other discharge line 34 which goes from said aperture to the unlocking line or the unlocking pressure port 16, allows a pressure reduction when the primary switching valve 23 against a scheduled normal operation at the same time or very shortly after the secondary switching valve 22 back into the in Fig. 4 shown initial position is brought, for example, by incorrect operation or power failure.
  • the pressure on the Stellaktor 8 of the securing element 7 can then be reduced to the tank T via the then open unlocking line or the still open unlocking pressure port 16 and the primary switching valve, cf. Fig. 4 ,
