Definitions

  • the invention relates to an attachment tool for construction equipment with a receptacle via which the attachment tool is connectable to a quick-change adapter of a construction machine, consisting of two receiving plates.
  • a fork carriage 10 is shown as an example of an attachment tool, which has a receptacle 14 consisting of two receiving plates 14, to which a quick-change adapter 16 of an excavator not shown here can be coupled.
  • the fork carriage 10 is conventional in itself and has two forks 18.
  • the quick-change adapter 16 is usually pivoted with its hook and a running between the receiving plate 12 tube 22 during Einkoppelvorgangs until it is bolted with a pin 24 with the receiving plates 12.
  • FIG. 3 which also represents the prior art, the mounting situation of the fork carriage 10 is shown to a hydraulic excavator 5, in which case the handle 7 of the hydraulic excavator is shown in two different positions. Once in a position in which the fork carriage 10 is discontinued (lower position) and a position in which the fork carriage 10 is moved as far as possible upwards (upper position).
  • the fork carriage 10 In its neutral position, the fork carriage 10 is aligned at a certain angle ⁇ with respect to the quick-change adapter. From the FIG. 3a results in how the angle ⁇ is set.
  • the stack height which is given by the lower end position of the fork carriage 10 is 1000 mm.
  • the position of the stem 7 the achievable stack height.
  • Object of the present invention is therefore to improve a generic attachment tool such that the attachment tool can be optimally adapted to use in the construction machine.
  • an attachment tool of construction machines has a receptacle via which the attachment tool can be connected to a quick-change adapter of a construction machine.
  • This receptacle consists of two receiving plates, wherein a receiving box in a predetermined angular position relative to the attachment tool with the receiving plates is connectable and wherein the quick-change adapter can be coupled to the receiving box.
  • the hole patterns of the fastening bores can be provided in the mounting plates in such a way that the mounting box can be connected to the mounting plates in three different main angular positions.
  • the attachment tool is a fork carriage.
  • a first angular position of the fork carriage is adjustable, in which a larger stack height can be accommodated on the fork carriage.
  • a second angular position a comparatively higher load capacity can be absorbed.
  • a mean stack height or load can be recorded in a middle angular position lying between them.
  • the invention thus consists in that now a modular system is provided to create a receiving box, via which a special attachment tool in different angular positions can be brought, so that the particular desired optimal use of the attachment to a specific construction machine is specifically adjustable.
  • the receiving plates can advantageously have a plurality of mounting holes which are arranged so that the receiving box in the predetermined angular position relative to the attachment tool with the receiving plates is connectable.
  • the receiving box but also on one side rotatably connected to the receiving surfaces, while on the other side relative to the receiving plates is adjustable to adjust the predetermined angular position relative to the attachment tool.
  • This angle adjustment can be done for example via a threaded spindle. Any other adjustment mechanism is also suitable here.
  • the recording plates are welded to the attachment tool.
  • the mounting plates are only screwed to the attachment tool, as this different mounting plates could be screwed in exchange for the attachment tool for different recording conditions.
  • the receiving box by Verbolzache or heavy-duty pins with the receiving plates connectable.
  • the hole patterns in the receiving plates can be selected so that the receiving box can take intermediate positions between the main angular positions.
  • FIG. 7 an embodiment of the present invention is shown, in which a fork carriage 10 is exemplified as a receiving tool.
  • the fork carriage 10 has two forks 18. These are slidably guided on a transverse traverse 26. At the transversely extending traverse and two receiving plates 12 are arranged, welded in the embodiment shown here.
  • FIGS. 4, 5 or 6 Depending on the appropriate mounting situation of the receiving box 30 then results in the FIGS. 4, 5 or 6 corresponding different kinematics or load or stacking height for the fork carriage 10th
  • the receiving box 30 consists of two side walls 34 and 36, which are interconnected via a tube 38 (advantageously as a welded joint).
  • a tube 38 in the upper region of the receiving box 30 is a receiving rod 22 for the hook 20 (not shown here) of the quick-change adapter 16 (also not shown here) provided.
  • the receiving holes 31 In the lower region of the receiving box 30 are the receiving holes 31 through which the Verbolzept or heavy-duty pins 32 are inserted to fix the receiving box 30.
