Definitions

  • Subject matter of the invention is quick coupling for changing excavator tools or type of closing for quick changing of excavator tools, which applies to the field of mechanical engineering, and solves the problem of tool breakage and also increases working force on bucket teeth.
  • Movable part (6) is inserted into the coupling main plate (5) so as to enable smooth movement, which is provided by the hydraulic cylinder (1), which is fixed to the coupling main plate (5) through the cylinder holder 2 (10) with the bolt (11). Movable part (6) is fixed through the cylinder holder 1 (9) with the bolt (11). And the coupling main plate (5) is welded by two lamellas (4), which are also the connecting joint with the arm of the machine, through holes (1a). Lamellas (4) are also reinforced by reinforcement (8), round reinforcement (12) and wedge reinforcement (14), whereas the ring with hole (13) provides positioning of bolts.
  • Female part (figure 16) is installed on various tools for working with the excavator, such as excavator buckets, couplings for hydraulic hammers, various rakes, etc...
  • Female part (figure 16) is composed of the bucket main plate (2), which has holes which catch hold of movable wedges (15) during coupling.
  • Cone part (3) which has a specific angle providing self-closeness of the joint between male (figure 17) and female part (figure 16), is welded into the holes of the bucket main plate (2).
  • Quick coupling for changing excavator tools operates in the following way: lamella in the form of a wedge first catches holes on the female part of the coupling, then the male and the female part are placed in a closed position and pressure in the cylinder is released, which causes the movable part to engage in the remaining two holes of the female part.
  • Figure 18 represents the diagram of the complete coupling composition.

Abstract

L'invention concerne un système d'accouplement rapide comprenant une partie femelle constituée d'une plaque principale à godets (2) et d'une partie conique (3); et et une partie mâle constituée d'une partie mobile (6) qui est soudée au support de cylindre (9) et d'une cale mobile (15) qui est renforcée par une cale de renforcement (7). La partie mobile (6) est insérée dans la plaque principale d'accouplement (5). Le cylindre hydraulique (1) est fixé à la plaque principale d'accouplement (5) par le support de cylindre (10) à l'aide d'un boulon (11). La partie mobile (6) est fixée par le support de cylindre (9) à l'aide du boulon (11). La plaque principale d'accouplement (5) est soudée par des lamelles (4) qui constituent le joint de liaison avec le bras de la machine, par des trous (1a). Les lamelles (4) sont renforcées par un renforcement (8), un renforcement circulaire (12) et un renforcement formant cale (14). Des anneaux (13) entourant des trous permettent d'obtenir des positionnements de boulons.
