Definitions

  • the invention relates to a coupling device for interchangeable attachment of a working device such as an excavator bucket on a boom or a vehicle, preferably a construction machine or a construction vehicle.
  • Such a coupling device is in all coupled to a boom or to a vehicle implements such.
  • excavator buckets digger signs, snow blades, various tools (spoons, drills, tilting paddles, chisel, milling cutter, support fork, ...), etc., useful.
  • the relatively high forces which are required to be stably taken over by this coupling device arise during the intended use.
  • the construction site operation with respect to moving parts is a very abrasive environment, which greatly increases the friction.
  • the invention relates in particular to coupling devices for implements with two mutually parallel and defined spaced cylindrical retaining bolts with exposed lateral surfaces, which are arranged on a mounting bar on the boom or on the vehicle, via a suitable acting linear actuator relative to each other adjustable coupling elements are locked behind engageable.
  • a coupling element as a solid gripping hook and the other coupling element as a movable closure hook, depending with matching recesses for engaging behind the retaining bolts, be formed.
  • Machine-actuated linear drives are also known.
  • hydraulic, pneumatic or electric linear drives are suitable as such. Since these are suitably remotely controllable from the cab from the rapid change of the implement is made possible.
  • EP1325196B1 discloses a related coupling device with hydraulic or pneumatic and electric linear drive, which acts on a displaceable in the plane of the retaining bolts, in guide rails locking slide, which extends and thereby locks one of the retaining bolts.
  • the disadvantage here is that the force that locks the retaining bolt, also jammed the locking slide in the guide rails so that it can be reliably solved in abrasive construction site operation only with a powerful linear drive, as he only hydraulically or pneumatically feasible in the available space , In particular, it can not be set in motion with a spatially fitting into the coupling device electric motor spindle drive.
  • a secure locking position is recognizable only by a non-unique visual inspection of the cab.
  • the object of the invention is to realize a robust and safe coupling device with integrated electric motor spindle drive, which overcomes the above disadvantages.
  • the object is achieved with the features of claim 1.
  • a coupling device for attachment of a working device at least two, by means of an electric linear drive relative to each other movable coupling elements and a locking means of the distance of the two coupling elements in the coupling position, wherein at least one coupling element is pivotally mounted and not rigidly connected to the linear drive
  • the linear drive is not rigidly connected to the pivotable coupling element, in particular via a knee joint connection, no harmful lateral forces and bending moments can be transferred from this to those.
  • a secure locking of the coupling position is ensured by means of the locking means on the electric linear drive.
  • this coupling element is free within the limits of its bearing clearance and its elasticity to snuggle the gripped retaining bolt, whereby a homogeneous power transmission takes place.
  • the pivotable coupling element has a stop surface which is perpendicular to the drive direction and against which the locking means in the form of a carriage displaceable via the linear drive strikes with suitable damping means in the coupling position.
  • the stop surface locks the distance between the two coupling elements located in the coupling position and thus secures them, but by the stop surface perpendicular to the drive direction and, avoided by the geometric definition of the pivotable coupling element, buckling force or other forces, in particular lateral forces and bending moments , which are transmitted from the pivotable coupling element on the carriage, the linear drive is subject to no buckling stress.
  • the carriage forms an at least partially concave driver, which engages with slight free play in an undercut of the pivotable coupling element, whereby it is pivotable by means of the linear drive in the open position. Since the force required for the opening / closing of the pivotable coupling element is directed perpendicular to the force transmitted from the retaining bolt, the tensile and compressive forces occurring on the linear drive are relatively low and thus also applied by an electric linear drive.
  • the axis of rotation of the pivotable coupling element is slightly offset in the opening direction, whereby jamming on the retaining bolt is additionally reduced.
  • the electric linear drive is a low-voltage (12V or 24V) operated spindle shaft motor, preferably with a corresponding reduction and in the execution of a rotating spindle on which the mother, which moves in a protected from external influences space, the necessary movement for fixing performs, which is realized in the abrasive construction site operation reliable operation of the coupling elements via a spatially integrated into the coupling device electric linear drive.
  • the carriage is assigned a suitable for detecting the coupling position electrical position sensor, whereby a corresponding coupling signal can be signaled in the cab.

  • the carriage 9 forms an at least partially concave driver 10, which engages with little free play in an undercut 11 of the pivotable coupling element 5b and thus forms a knee joint, whereby the pivotable coupling element 5b by means of a prestressed spring 13 in the form of a torsion spring and the Linear drive 4 in the coupling position (Fig. 5, 6) and by means of the linear drive 4 in the open position (Fig. 1, 3) is pivotable.
  • the carriage 9 is associated with an electrical position sensor 12 for detecting the coupling position (FIG. 5) in the form of a magnet and HALL sensor.
  • the electrical linear drive 4 which is completely spatially integrated into the coupling device 1, is realized as a 12-24 V self-locking spindle shaft motor 4 a with a sealed housing 4 b for the rotating spindle on which the running nut 4 c is mounted.
  • the control of the electric linear drive 4 and the signaling of the clutch signal takes place directly in the (not shown) cab of an excavator.
