Definitions

  • the present invention relates to a quick coupling for the temporary attachment of work tools to a boom of a construction machine according to the preamble of claim 1.
  • the present invention has for its object to provide a quick coupling of the type described above, which eliminates the disadvantages of the known solutions and which is simple to use and their Functionality is not questioned by complicated mechanisms.
  • FIG. 1 you can see an essentially commercially available spoon 1, such as is used for example on excavators and similar construction machinery.
  • This bucket 1 differs from the usual work tools of this type only in that the means with which it is connected to the excavator boom differ from the commercially available connecting means, since they are part of the quick coupling according to the invention and essentially form a frame 2 which comprises two side frame walls 3 and 4, which are connected to one another by two bolts 5 and 6.
  • the frame 2 is advantageously along the welded side frame walls 3 and 4 along on the bucket 1 in order to be able to transmit large forces and moments from this to the excavator boom.
  • Fig. 2 illustrates how the counterpart of the frame 2, a box 7, can be connected to the end of an excavator boom 8.
  • the box 7 comprises two side box walls 9 and 10, which are connected to one another by a slide housing 11 and two half-shells 12 and 13.
  • Each box wall 9 and 10 has two pin eyes 14 and 15, one of which is used to receive a bucket pin 16 and the other to receive a bucket cylinder pin 17, by means of which the box 7 with the excavator boom 8 and a bucket cylinder 18, respectively.
  • a slide 20 is accommodated in the slide housing 11, the function of which is described below.
  • the expert recognizes the box 7 in partial longitudinal section, which is placed so that the slide housing 11 and the slide 20 and a support structure 21 for a pivotable unlocking bolt 22 are cut.
  • the box wall 9 shown the two bolt eyes 14 and 15 are visible.
  • the two half-shells 12 and 13 can be connected to the box walls 9, 10, which also applies to the slide housing 11, or its top and bottom plates 23 and 24.
  • the slide 20 is arranged in a spring-loaded manner, in such a way that advantageously two spiral springs 25, of which only one is visible, continuously push it out of the slide housing 11.
  • a bolt 6 of the frame 2 coming into the half-shell 13 can be fixed in the latter.
  • the slide 20 can be pushed against the spring force under the half-latch 13 in such a way that it becomes accessible for the bolt 6 of the box 7, respectively.
  • the bolt 6, usually fixed therein by means of the slide 20, from the latter can be pulled out.
  • the unlocking bolt 22 can be mounted in two side walls 26 of the supporting structure 21 by means of a shaft 27. But it can also be pivotally connected to the box 7 in any other appropriate manner. In order to facilitate the handling of the slide 20, it can be slightly beveled in its front area, which also makes it possible to absorb any play between the bolt 6 and the half-shell 13 and the slide 20.
  • the slide housing 11 extends from one box wall 9, 10 to the other, it is not absolutely necessary that the slide 20 is also as wide. Its width can be limited to part of the box width. If necessary, its front area can also be toothed in order to increase the functional reliability of the quick coupling according to the invention, in particular in the case of solid contamination.
  • An eccentric can take the place of the unlocking bolt 22, in particular if for some reason it is to be avoided that the normal position of the slide 20 is the closed position. Any other mechanism that enables the slide 20 to be moved can also be provided on the box 7. So it is easily possible to use a pneumatically or hydraulically remote-controlled slide unlocking and locking device.
  • FIG. 4 shows a frame 2 according to the invention, as can be connected to an excavator bucket 1, for example according to FIG. 1, in a side view.
  • the two side frame walls 3, 4 each have a recess 28, which ensure that the bolt eyes 15 of the box 7 do not collide with the frame 2.
  • FIG. 5 illustrates how the connection of a bucket 1 with an excavator boom 8 is made from the side by means of a quick coupling according to the invention.
  • connection of the two quick coupling parts frame 2 and box 7 is done most simply by attaching the box 7, which is attached to the excavator boom 8 and the deflector 19, to the bucket 1, or. the associated frame 2 is moved up so that the half-shell 12 more or less encompasses the bolt 5 from below, so that the latter comes to rest in the former.
  • the bucket 1 By lifting the bucket 1 by means of the excavator boom 8 and extending the bucket cylinder 18, it is then caused that the bolt 6 of the frame 2 and the half-shell 13 of the box 7 meet.
  • the half-shell 13 is subsequently or simultaneously opened when the spoon 1 is received and the box 7 is pivoted in such a way that the bolt 6 due to the heavy weight of the spoon 1 suspended on the bolt 5 in the half-shell 12 of the box falls into the half-shell 13 by itself.
  • the bolt 6 is fixed in the half-shell 13 by a subsequent manual or automatic advancement of the slide 20. Work with the work tool connected to the excavator boom 8 in this way can begin.
  • the quick coupling according to the invention has a very simple, reliable mechanical structure that is not susceptible to malfunctions. It enables quick and easy connection and disconnection of work tools to any type of machine tool boom. Thanks to the simple construction of the quick coupling according to the invention, it can easily be adapted to the specific requirements of certain work tools and booms, because it should generally suffice to shape the frame walls 3 and 4 so that the frame 2 can be welded onto the work tool. Since the box 7 is advantageously designed so that it can be connected to the boom of the individual machines by means of the bolts 16 and 17 without modifications to the booms instead of the conventional work tools, only the box width, respectively. adapt the length of the half-shells 12 and 13 and the arrangement of the bolt eyes 14 and 15 in the box walls 9 and 10 to the specific circumstances.
