Definitions

  • the invention relates to a mounting bracket for releasably connecting an attachment to a basic device, e.g. a boom of an excavator with a construction machine or a construction vehicle, the mounting bracket consisting of two coupling parts, one of which is connected to the attachment and the other to the basic unit, and bolts are provided for connecting the coupling parts, which are parallel to one another at a radial distance are arranged.
  • a basic device e.g. a boom of an excavator with a construction machine or a construction vehicle
  • the invention is based on the object of designing such a mounting bracket in such a way that the connection of the two coupling parts to one another is as simple as possible and nevertheless a securing for fixing the two coupling parts to one another is possible.
  • the invention provides that the bolts are firmly connected to the one coupling part and that the second coupling part has claw-shaped supports for the bolts and at least one securing device for fixing at least one of the bolts.
  • This design has the advantage that one coupling part can be hooked into the second coupling part, for example, from above, or else can be initially fixed by gravity by means of a relative rotary movement of the one coupling part to the other.
  • An advantageous embodiment of the invention provides that at least one claw pivotally mounted on the second coupling part is provided as a safety device, which engages over one of the bolts in the working position.
  • Figures 1 to 6 show views or partial views of a first embodiment. 6 is an enlarged partial view for explaining the operation of the safety device.
  • first coupling member 1 and a second coupling member 2, e.g. the first coupling member is detachably connected to a construction machine and the second coupling member 2 is formed at the inner end of an excavator boom. It can be seen that the attachment of these coupling parts can also be interchanged.
  • the second coupling member 2 is presumably connected to the end piece 3 of an add-on part and, in addition to a support surface, comprises at least one upper retaining bolt 4 and one lower retaining bolt 5, the axial directions of which are essentially horizontal.
  • the first coupling part 1 comprises cross struts 6, at the ends of which cylindrical holding devices 7 are arranged, which can be hung on a construction vehicle or the like. It is also conceivable that such a holding part 7 also forms a vertical shaft about which the attachment 3 is to be pivotably held on a construction vehicle.
  • At least one holding flange 8 is fixedly connected to the cross struts 6, in the exemplary embodiment shown two such holding flanges are arranged at a horizontal distance from one another and work together with two corresponding flanges of the second coupling part, each of which carries two of the holding bolts 4 and 5.
  • Each coupling flange 8 has an upper support 9 and a lower support 10.
  • the upper support 9 overlaps the upper retaining pin 4 approximately over half of its circumference from above.
  • the lower support 1o has a curved support surface, which engages around the lower retaining bolt 5 from below at least to about a quarter of its circumference or supports it downward and towards the first coupling part.
  • the lower bolt 5 is secured after hanging the second coupling part in the coupling flange 8 by a pivotally mounted claw 11, which is pivoted downwards and engages around the lower bolt 5 from above about half of its circumference so that it without Play and immovable is held relative to the lower support 1o.
  • the claw 11 is dimensioned for all occurring loads. It is held in its working position shown in solid lines in FIG. 1 by a tension spring 12 which engages an extension 13 of the lower cross member 6.
  • the claw 11 is pivotally mounted on the coupling flange 8 about a bearing pin 14. This pivot pin is dimensioned for the greatest possible load, since it must absorb the forces acting on the i bearing pin 5 via the claw 11.
  • FIGS. 1 to 6 different securing devices are provided according to the invention, one of which is shown in the first exemplary embodiment according to FIGS. 1 to 6. To explain the mode of operation, reference is made particularly to FIGS. 5 and 6.
  • the coupling flange 8 has a bore 15 which is aligned with the bore of a hollow hub 16 on the claw 11 in the working position of the claw 11.
  • the outer end of this hollow hub is chamfered, so that two inclined surfaces 17 are formed, of which the one not visible in FIG. 5 lies above the plane of the drawing in FIG. 5 and is flush with the surface 17.
  • a locking pin 18 is slidably mounted, which is acted upon by a compression spring 19 which is supported in the hollow hub on a collar 20.
  • the compression spring 19 When the compression spring 19 is relaxed, the locking pin 18 engages in the bore 15 in the coupling flange 8, as shown in FIG. 5.
  • a pin 21 is screwed or welded to the outer end thereof, which carries a U-shaped tab 22 on which a pulling rope 23 engages.
  • This pull rope is shown in Figures 1 and 6 in solid lines in the position that the parts in Fig. 5 occupy in the locked position.
  • the pull rope 23 is actuated.
  • the pin 21 slides on the inclined surface 17 to the extreme end of the hollow hub 16, so that the locking pin 18 comes out of engagement with the coupling flange 8.
  • the claw can then be raised against the force of the spring 12 and the two coupling parts can be separated from one another.
  • a device visible in FIGS. 3 and 4 is provided for actuating the pull cable 23.
  • a protruding projection 24 is attached to the first coupling part.
  • On this an angle lever 25 is pivotally mounted about a pin 26 which carries on its inner lever arm 27 a device for holding the pull cable 23.
  • two coupling flanges 8 are arranged at a distance from one another on the first coupling part 1, each of these coupling flanges carrying a claw 11, so that two pull cables 23 are required to actuate the locking bolts.
  • These two traction ropes are integrally connected to one another and guided together via a roller 28 which is mounted on the inner leg 27 of the angle lever 25.
  • the pull rope 23 is tensioned and the locking bolts 18 are lifted out.
  • the angle lever is pivoted into the position shown in solid lines, the traction cables are relaxed and the locking bolts are thus brought into the locking position under the force of the spring 19.
  • a bore 29 is arranged both in the coupling flange 8 and in the claw 11, these bores corresponding on the one hand to the bore 15 and on the other hand to the hollow hub 16. Securing the claw 11 Against unintentional opening is done in this greatly simplified embodiment simply in that a locking pin is inserted by hand through the holes 29 aligned in the working position of the claw 11. Such a safety measure is sufficient where relatively light or lightly loaded parts are to be coupled to a vehicle and / or in which the coupling device is easily accessible.
  • a safety device schematically shown in side view in FIG. 8 is somewhat more complex and therefore safer.
  • the lower support 3o for the lower retaining bolt; 5 can encompass in a somewhat modified area compared to the exemplary embodiments otherwise shown. This essentially depends on the respective application.
  • the claw is preloaded in the locked position by means of a tension spring 12.
  • a locking pin 31 is attached to the lower support.
  • a securing claw 33 is pivotally mounted on the claw 11 about a bearing pin 32.
  • the hook-shaped end 34 of this securing claw engages in the locking position on the locking pin 31 and thus prevents the claw 11 from being raised unintentionally.
  • This locking claw is preloaded into its locking position by means of a tension spring 35 with respect to the first coupling element.
  • a traction rope 36 may also serve in this training f U currency, for example, which is connected to the outer lever arm of the securing claw 33rd
  • the second coupling part 2 is designed in the manner described above.
  • the first coupling part is rigidly connected to a construction vehicle 42 and essentially comprises only at least one coupling flange 44 and lower support and cooperates with the retaining bolts 4 and 5 of the second coupling part 41.
