Definitions

  • the present invention relates to a coupling device of a tool at the end of the boom of a machine such as a hydraulic shovel.
  • this coupling device has a number of disadvantages.
  • the gripping of the tool placed on the ground with a view to its coupling imposes an alternating movement of the coupler.
  • the coupler must be brought closer to the arrow so that the hooks grip the bar connected to the tool then, in a second step, the coupler must be moved away from the arrow to get closer to the interface and allow locking.
  • this reciprocating motion is relatively complex and time consuming to execute. This is accentuated by the fact that the visibility of the operator during this operation is reduced because the coupler hides the area of the hooks and the locking system.
  • the risk of losing the tool in the locking phase is important because the distance of the coupler relative to the arrow can lead to the output of the bar of the tool out of the hooks.
  • the present invention aims to overcome the disadvantages mentioned above.
  • the invention relates to a coupling device of the aforementioned type, in which the opening of the hooks is directed towards the outside of the device, opposite said coupling zones, in the coupled position. coupler and interface.
  • the hooks are arranged so that the pivoting of the coupler relative to the arrow about its pivot axis and in a given direction can cause the engagement of the bar connected to the tool in said hooks and the approximation of the coupling zones. by rotation about the axis of the interface bar relative to the coupler.
  • the coupling zone of the coupler forms a cavity and the coupling zone of the interface forms a protruding portion adapted to be engaged in said cavity, the protruding portion and the cavity having through orifices. aligned in the coupled position, in which is inserted at least one bolt belonging to the second locking means of the coupler, the bolt being arranged to press an end face of the projecting portion of the interface against the bottom of the cavity of the coupler in locking position.
  • the coupling operation of the interface and the coupler does not require reciprocating movement and does not involve any risk of loss of the tool. Indeed, "winding" of the hooks around the bar causes the relative movement of the interface and the coupler to the coupled position.
  • each hook has substantially the shape of a U, each leg of which comprises an arcuate entrance surface centered substantially on the pivot axis of the coupler, said input surfaces being angularly offset. relative to one another and intended to guide the bar towards the bottom of the hook when the coupler pivots relative to the arrow about its pivot axis.
  • the upper surface located foremost thus allows the initial positioning of the coupler relative to the tool and its guidance, while the lower rearmost surface allows, when the bar rests on it, to lift the tool after pivoting of the coupler.
  • each hook may comprise a first substantially flat portion and parallel to the median longitudinal plane of the coupler, intended to cooperate with a lateral face of the interface, extended by a second portion inclined towards said median longitudinal plane when one gets closer to the first flat part.
  • This allows to guide the movement of engagement of the bar in the hooks, as well as the lateral centering of the interface relative to the coupler.
  • This geometry is all the more interesting because the operator only has two degrees of freedom in rotation (boom and coupler) to perform the coupling operation of the tool to the arrow, and no longer three (the third degree of freedom corresponding to the rotation of the bucket with respect to the arm in the most usual case of a bucket quick coupler fixed at the end of the arm).
  • the first locking means of the coupler may comprise a bolt which, in the locking position, passes through the hook so as to form a retaining housing of the bar against the bottom of the hook.
  • first and / or second locking means may be movable in translation between their locking position and their release position.
  • locking means movable in rotation a much more compact system is obtained, requiring fewer parts and a simplified control system.
  • a face of the bolt intended to come into contact with the interface or the bar, opposite the coupler is inclined with respect to its direction of displacement, so that the displacement of said bolt towards the locking position plates a face. of the interface or a face of the bar against a face of the coupler. Thanks to this structure, it is possible to make up the existing clearance between the different parts and to obtain a satisfactory locking.
  • the ends of the bar, intended to be engaged in the hooks are each surrounded by a sleeve
  • the sleeve may have a flat surface intended to cooperate with the inclined face of the bolt of the first locking means.
  • the invention relates to a machine such as a hydraulic excavator, comprising on the one hand an arrow at the end of which is mounted a coupling device as previously described, the pivot axis of the coupler being located substantially in the central portion of the coupler, and secondly a cylinder mounted on the boom and connected to a first end portion of the coupler to pivot it relative to the arrow, the hooks being formed at the second end portion of the coupler.
  • the opening of the hooks is directed towards the arrow, which makes it possible to obtain very good visibility for the operator having to grip the tool.
  • the figure 1 represents a machine 1 such as a hydraulic excavator, having an arrow 2.
  • a coupler 3 intended to be coupled to an interface 4 itself mounted on a tool 5, in order to allow the coupling of this tool to the arrow.
  • the tool 5 illustrated on the figure 1 comprises an arm 6 and a bucket 7, but the invention applies to the coupling of other tools, such as hammers, hydraulic clamps, etc.

  • each hook 13 has substantially the shape of a U having first and second legs 15, 16 and a bottom 17.
  • the first leg 15 is located closer to the axis 9 than the second leg 16 and is more long as this last.
  • the branches 15, 16 have at their end opposite the bottom 17 an inlet surface 18, 19 in the form of a circular arc centered substantially on the pivot axis 9 of the coupler 3.
  • the input surfaces 18, 19 are angularly offset from one another by an angle ⁇ of the order of 15 to 25 °, the input surface 18 of the first branch being further away from the bottom 17 than the input surface 19 of the second limb 16.

  • each hook 13 When the coupler 3 is seen from the side (see figures 1 and 6 ), if a line is drawn between the axis 11 of the bearing 10 and the axis 20 of the bottom 17, the opening of each hook 13 is directed towards the line containing the pivot axis 9 of the coupler 3 In addition, in the embodiment shown, the branches 15, 16 of each hook 13 extend generally perpendicularly to this line.
  • the hooks 13 form two housing receiving an end portion of the bar 14, as illustrated in particular on the figure 4 .
  • Each housing is delimited by the bottom 17 of the hook 13, as well as the branches 15, 16, which are connected and closed laterally by a substantially longitudinal wall 24.
  • the receiving housing of the bar 14 is also provided with openings for the entry of said bar into the housing.
  • Orifices 27 are formed in the first and second branches 15, 16. Their function will be indicated later.
  • each branch 15, 16 has a substantially flat portion 28 and parallel to the median longitudinal plane of the coupler 3, here substantially in the form of a ring ( Figures 3 and 4 ), extended by an inclined portion 29 towards said median longitudinal plane when approaching the flat portion 28.

  • the coupling zone of the interface 4 forms a projecting portion 31 able to be engaged in the cavity 30 of the coupler 3 ( figure 6 ), and therefore preferably has a shape complementary to that of said cavity 30.
  • the projecting portion 31 and the cavity 30 comprise longitudinally-opening orifices, respectively 32, 33, which are aligned in the coupled position of the coupler 3 and the interface 4.
