Definitions

  • the invention relates to a device for excavating individually laid paving stones according to the preamble of independent claim 1.
  • the invention has for its object to provide a device with which the lifting of individual paving stones or paving slabs, which are also laid in an association, is facilitated.
  • one or two lamellae which are so thin that they can be inserted into the existing joints between laid stones or slabs, are pressed so deeply into this joint that they have a resilient abutment knob under the reach for the lifting stone.
  • These abutment knobs are preferably punched out and bent out of the material of the lamella, spring steel, so that not only the abutment knobs under the stone become effective, but also the resilient abutment knobs pressing against the stone to be lifted in the area of the stone joint bring about frictional resistance, which, when lifting the slat, can result in the stone to be lifted out without a slat reaching under the stone.
  • a lifting device acts on the plungers connected to the lamellae, preferably a hydraulic cylinder, which acts on the plunger with the interposition of a yoke beam, so that the stone to be lifted is now evenly lifted.
  • the actual lifting device is supported on the floor by a support frame, this support frame surrounding the stone to be lifted, so that different support frame sizes are provided depending on the stone or plate sizes.
  • the support frame has a bracket on which a hydraulic cylinder is arranged, the pump of which can be actuated via a hand lever, this hydraulic cylinder engaging under a transverse yoke beam which engages on the tappets via lifting arms. This enables the stone or slab to be lifted quickly and without any problems and, above all, evenly.
  • a paving is shown and a stone P to be lifted out of this paving composite.
  • a device is provided which essentially consists of one, but preferably two, slats 1, 6, each of which can be displaced in a C-shaped guide 2, 7 with carrier 30.
  • These slats 1, 6 consist of thin spring steel, for example from a 0.8 mm thick spring steel sheet, from which abutment knobs 3 are punched out and bent out, the outermost end of each abutment knot being about 2 cm above the front plane of the slat 1 or 6 stands out.
  • each lamella 1 or 6 a plunger 4 or 5 guided in the carrier 30 engages, each of which has a thickened end 9, 10.
  • This plunger is attached in the simplest manner to the lamella 1 in that the plunger 4 or 5 has a lower thickened end 25, the thickened end 25 being fixed on the lamella 1 by screwing means 26. This makes it easy to replace the slat.
  • Each C-shaped guide 2 or 7 also has a support surface 8 with which the C-shaped guide 2, 7 is supported on the stone not to be lifted.
  • a support frame 11 which surrounds the stone P to be lifted and is supported on the surrounding stones, this support frame 11 having a base frame 12 which, in the exemplary embodiment shown, carries a base frame bracket 14 on which a lifting cylinder 15 is supported which is preferably designed as a hydraulic cylinder, the pump of which can be actuated via a hand lever 24.
  • the piston rod of the lifting cylinder 15 engages under a yoke beam 16 which carries lifting arms 17 and 18 in a displaceable manner.
  • the lifting arms are displaceable in that they encompass the yoke beam 16 by means of sleeves 27, 28, the sleeves 27, 28 each being able to be fixed in position by means of screws 29.
  • each lifting arm 17 or 18 a holding device 19, 20 is provided, each consisting of a bracket 22, which has a slot 23.
  • the open ends of the slots 23 are oriented differently, so that the brackets 22 can be guided with their slots 23 over the plunger 4 by a rotational movement of the yoke beam 16, the thickened end 9 of each plunger 4 or 5 via the console 22 takes hold.
  • the tappets 4 and 5 can also be raised, and thus the lamellae 1 and 6 can be raised and finally thereby raised of the stone P.
  • the stone P By carefully operating the hand lever 24, the stone P can be slowly and gently lifted, so that this stone can be lifted out without disturbing the surrounding stone compound.
  • the operation with the device according to the invention is as follows: After, as shown in FIG. 3, the C-shaped guide 2 is placed over a stone joint, the lamella 1 is driven into the stone joint by striking the thickened end of the plunger 4 with a striking tool, the abutment knobs 3 being bent outwards being bent deform a little inwards and thereby cause a high frictional resistance when lifting the stone later.
  • the lamella 1 can be driven in until the lowermost abutment knob 3 comes out of the stone joint and engages under the stone P to be lifted.
