Definitions

  • the invention relates to a grave tool, such as a spoon or a blade, or gripping tool with a gripper shell, to which at least one tooth tip is attached, according to the preamble of claim 1.
  • peel grab for material handling affected are used in particular for loading bulk materials, fine and coarse scrap, demolition material or for loading VA steels.
  • orange peel grabs for such a material change it has hitherto been customary in the applicant for worn gripper peeling tips to be severed and new gripper peeling tips to be welded on.
  • screw or plug tooth tips which are replaced after reaching the wear limit against new tips.
  • At least one Tooth tip is attached, wherein the digging or gripping tool at least one tooth holder is arranged, in which the at least one tooth tip inserted, trackable in length and securable by securing elements.
  • the tooth tip protrudes laterally or laterally out of the tooth holder to allow replacement and tracking by knocking.
  • Object of the present invention is to develop generic grave or gripping tools such that the replacement of the at least one tooth tip is inexpensive and easy.
  • At least one tooth holder is arranged on the digging tool or on the gripping tool, in which the at least one tooth tip can be inserted, tracked and secured in length.
  • a long tooth tip is provided at the lower end of the gripper shell, which is guided in an example welded-on tooth holder and is secured against failure.
  • the tooth holder is designed in a favorable shape, so that the penetration is not disturbed. Through the front opening of the tooth holder, the tooth tip protrudes outward to the extent that the gripper closes well.
  • the tooth tip is designed such that it is trackable in length and fixable after appropriate tracking, that is securable.
  • the tooth tip has on one side a plurality of stepped-like arranged pockets, wherein in the tooth holder at a corresponding point an opening is provided so that the pockets are accessible from the outside.
  • the tooth holder and / or the tooth tip of wear-resistant material such as cast steel exist.
  • a wear plate of wear-resistant material can advantageously be applied via the tooth holder.
  • the tooth tip can laterally have a plurality of bores, which forms a perforated grid for receiving securing elements.
  • screw or clamping elements such as wedges, clamping tongues or the like can be used.
  • FIG. 1 is a customary gripper shell 10 is shown, the tip is cut to length. Instead of the cut-to-length tip, a tooth holder 12 is welded to the gripper shell 10, which has a receiving bore for receiving a tooth tip 14.
  • the tooth tip 14 is made of wear-resistant cast steel.
  • the shape of the tooth tip results in particular from the sectional views according to the FIGS. 3 and 4 , This shows that the tooth tip has a series of juxtaposed holes 16, which form a hole pattern for receiving locking pins.
  • the locking pins 18 can, as in FIG. 4 shown on the one hand through the holes in the tooth tip 14 and on the other hand are inserted through corresponding holes in the tooth holder 12. Preferably, they are so-called Connex-Schwerstanntere. In the embodiment shown here, as in the FIGS. 1 . 3 and 4 shown two adjacent locking pins 18 provided.
  • the locking pins 18 can be removed and the tooth tip can be pulled out around a hole pattern, so that the locking pins can be taken again.
  • this has at one end step-like arranged pockets 20, which form a kind of stair gearing.
  • a tool for expelling the tooth tip can engage in the staircase toothing.
  • this tool not shown here, which can be designed similar to a chisel, and a hammer, the tooth tip 14 can be expelled.
  • a wear plate 24 can additionally be used.
