Definitions

  • the invention relates to a device for breaking off piles, said device being provided with a frame built up of a plurality of links, which are interconnected at both their ends, to form a closed loop, by means of hinge pins and ears forming part of the links, said loop forming a passage for accommodating a pile to be broken off, whilst at least some of the links each support a setting cylinder, by means of which a cutter can be moved to and fro, such that a part of the pile located inside the passage can be broken by the cutters.
  • Such a device is e.g. known from NL-A-8,400,404 or DE-A-3,541,786 ( Figures 6, 7).
  • the object of the invention is to obtain a device of the above kind, wherein the above risk can be simply avoided.
  • this objective can be accomplished in that the links are provided with co-operating stops for limiting the pivoting of the links in a direction in which the free ends of the cutters supported by the links in question move towards each other, all this such that the cutters cannot touch each other in the position in which they are completely moved out.
  • said supporting parts form an essentially rigid annular means, which is pivotal forwards and backwards about its central axis in order to allow the tools to act on a concrete covering of a pipe.
  • the device shown in Figure 1 is built up, in a manner similar to the manner which is described in the above-mentioned Dutch Patent Application No. 8,400,404, of a plurality of links 1, which are each provided with a block 2 in which a cutter 3 is movably guided in its longitudinal direction.
  • a hydraulic setting cylinder 4 On one side of the block 2 there is mounted a hydraulic setting cylinder 4, by means of which the cutter 3 can be moved to and from in its longitudinal direction.
  • a pressurized fluid can be supplied to the setting cylinder 4 in question by means of pipes (not shown).
  • a number of such links 1 are interconnected by means of hinge pins 5, in order to form a closed loop-shaped unit.
  • the device thus built up of a number of links can e.g. be suspended from a crane or the like by means not shown, and be moved by means of said crane over the upper end of a concrete pile 6 which has been driven into the ground.
  • the cutter into the concrete of the pile by means of the setting cylinders 4, as is illustrated for one of the cutters by means of dotted lines in the Figure, the concrete of the pile can be broken in order to expose the reinforcement present in the pile.
  • the links are provided with stops 7 on both sides of the blocks 2.
  • Said stops 7 are formed and arranged such that when two adjacent links 1 pivot about the hinge pin 5 interconnecting said links in a direction in which the ends of the cutters 3 move towards each other, said stops will touch each other at a certain moment and thus prevent further pivoting in that direction.
  • stops 7 will also depend on the length of the stroke of the cutters 3 or the lengths of the cutters 3 that can be used in the device.
