Definitions

  • the present invention relates to improvements to devices for attaching a tool to the end of the arm of a shovel hydraulic or the like.
  • a quick coupler has two parts, a first part, or hooking member, which is worn by the end of the arm and a second part which is rendered secured to the tool.
  • the second part consists mainly of a tree, or by two pins, fixed relative to the tool.
  • the first part which is articulated at the end of the arm, presents, in its form the simpler, a hook forming a semi-cylindrical cradle likely to be engaged on the tool shaft when the latter rests on the ground.
  • a device comprising a hooking member articulated on the end of the arm and comprising a cradle capable of grasping a rendered tree integral with the tool, the rotation of the fastening member being limited by two stops, one of which is located at the end of an extension of said attachment member, while the other is carried by the tool.
  • the locking of the tool on the latching member is achieved by joining the two stops together with a screw. Of this way, it is opposed to the tool shaft coming out of its cradle. However, nothing is planned to oppose the phenomenon of matting producing between the tree and the cradle.
  • the present invention which remedies this drawback, is relative to a device for attaching a tool to the end of the arm of a shovel hydraulic or the like using a quick coupler consisting of a hooking member articulated on the end of the arm and comprising a cradle likely to seize a tree, or trunnions, returned integral with the tool, and it is characterized in that the member hooking has a stop, capable of cooperating with a stop, arranged at the periphery of the shaft or of the tool journals, when the hooking member is locked on said tool.
  • 1 is the end of the usual arm of a charger on which it is advisable to fix a tool 2.
  • tool 2 is a jackhammer, i.e. a tool that is subjected to alternating forces.
  • the fastening member 3 is produced at by means of two identical hooks, forming cradles, joined together by, at least, a crosspiece 5. Each hook is located on the small branch of an L-shaped piece 6.
  • the attachment member 3 is articulated at the end of the arm 1 through a shaft 7 and can pivot around the axis of said tree through links 8 and 9 subjected to the action of a cylinder whose piston rod appears at 10 in the drawings.
  • the tool 2 has a susceptible tree to be gripped by the cradle formed by the hooks 4.
  • the aforementioned tree can be limited to two lateral pins 11.
  • Figure 1 shows the tool hooked under the arm 1.
  • the rod 10 By moving the rod 10 according to arrow F 1 we rotate the fastening member 3 in the same direction until the latter automatically locks to the part upper part of the tool (position shown in Figure 2).
  • the means for achieving this locking have not been shown but are described in the aforementioned European patent No. 438931.
  • the attachment member has a stop 12 likely to cooperate, when the tool is locked, with a stop 13 provided on the tool.
  • the stop 12 has a concave contact surface 14 and the stop 13 has a convex contact surface 15, stop 12 being fixed relative to member 3 and that 13 being fixed by compared to tool 2.
  • the two surfaces 14 and 15 move on a fictitious cylinder the axis of which coincides with that of the journals 11. In all rigor and for mechanical reasons, surfaces 14 and 15 operate on two separate fictitious cylinders, the difference radii between the two cylinders resulting from mechanical play necessary between the two surfaces. It is desirable that this game be as small as possible.
  • the stop 12 pivots in the same direction and comes to position, at the end of the locking, above the stop 13. In the latter position, the forces to which the tool is subjected (those exerted according to arrow F2) are transmitted to the latching member by the stop 13 which cooperates with that 12 and not by the pins 11. The efforts exerted in the opposite direction are collected by the semi-cylindrical cradle formed by the hooks 4.
  • the stops 12 and 13 are located in separate planes of those containing the brackets.
  • the stop 13 is disposed between the pins 11 and that 12 is made integral with cross 5.
  • Figure 3 shows the attachment of a bucket 16 using a attachment member 3.
  • the bucket 16 comprises a shaft 17, fixed relative to said bucket.
  • the shaft 17 has two stops 18 and 19, diametrically opposed, likely to cooperate, when the bucket is locked, with two stops 20 and 21 carried by the attachment member 3.
  • the stops have contact surfaces 22 and 23 similar to those 14 and 15.
  • stops 20 and 21 are arranged outwards relative to the axis of the shaft 17, but this provision can be reversed as shown in the figure 5.
  • the tree 17 has two stops 24 and 25 capable, when the tool is locked, of cooperate with two stops 26 and 27 carried by the member 3.
