Definitions

  • the present invention relates to a concrete crusher according to the preamble of claim 1.
  • Such concrete crushing tongs are used to break off structures made of reinforced concrete.
  • the pliers move the concrete crusher on the one hand the concrete is broken and on the other hand in the same sequence of movements the reinforcing iron is cut.
  • Such concrete crushing tongs are known.
  • a concrete crusher is shown in US-A-5 183 216.
  • WO-A-96/02708 shows a concrete crushing tongs according to the preamble of the independent claim, the two Pliers jaws, each with concrete crushing areas and Cutting edges are provided.
  • the concrete crushing areas are over the Cutting edges protruding, which is to avoid breaking of the concrete is triggered by the cutting edges used to cut the Reinforcing iron are provided and therefore have a relatively sharp edge should.
  • the breaking edge and the cutting edge are all-round, i.e. In order to be able to optimally cut the reinforcing bars, the concrete breaking edge may do not protrude too much beyond the cutting edge. This allows do not avoid the cutting edge by breaking the concrete is heavily used, which can result in severe wear and tear expresses itself in declining cut quality for the reinforcing iron.
  • the object of the present invention is now a To create concrete crushing pliers, in which the renewal of the cutting edges can be carried out without long downtimes of these pliers, and in which an optimal refraction of the concrete is achieved.
  • each of one with a Bend block are formed on the side areas of the first Pliers jaw and the second pliers jaw attached.
  • the convex surface in the provided with a corresponding support surface
  • Another advantageous embodiment of the invention consists in that a guide rib on the convex surface of the previously described block attached, which is aligned in the longitudinal direction to the convex surface is and runs in the middle, the respective support surface of the receiving pocket is equipped with a groove corresponding to the guide rib, in which the guide rib in the inserted state of the block in the pliers jaw intervenes.
  • the block is optimally in the pocket of the respective jaws.
  • Another advantageous embodiment of the invention consists in that elements at the end regions of the support surfaces of the receiving pockets are attached, which are provided with stop surfaces on which the End faces of the blocks are in the inserted state in the receiving pockets are.
  • the jaws on each side area two each arranged in series, formed by the blocks Cutting elements are provided, which can be screwed onto the pliers jaw Teeth are kept in the receiving pockets.
  • the tips of the teeth are protruding beyond the cutting edges of the cutting elements, causing breakage of the concrete is at least introduced through these teeth and the Cutting edges are thus protected.
  • Another advantageous embodiment of the invention consists in that the bend of the block forming the cutting elements is circular is, which makes the contact surface optimal and the production of the blocks and the Recording bags is simplified.
  • the one between the two cutting edges lying concave surface of the blocks has a curvature and the wedge angle the cutting edge becomes larger than 90 °.

  • Another advantageous embodiment of the invention consists in that on the frontal area of the first and second jaws of each a plate forming the second cutting element is attached, each with a side surface on a corresponding support surface of the receiving pocket rests and thus optimal power transmission to the jaws is achieved becomes.
  • This plate is supported on the support surface adjacent wall of the first jaw or the second jaw and is screwed against it. So this plate is also easier Way interchangeable.
  • the two side surfaces of the plate are advantageously provided with indentations and protrusions along which the cutting edge runs.
  • the plate can be inserted into the receiving pocket in such a way that one or the other of the two cutting edges is in use. Also in this way the material is optimally used.
  • Another advantageous embodiment of the invention consists in that the plate between the two front teeth of the first and the second pliers jaw is arranged, the tips of the teeth over the Cutting edge of the plate are protruding. This will break the concrete in turn at least initiated via the teeth, the cutting edge of the This protects the plate.
  • the teeth are advantageously arranged in the jaws of the pliers in such a way that when the pliers are closed, the back teeth on the impact the concrete part to be broken off and the concrete is broken in this area and only then engage the front teeth. This will make it Breaking the concrete easier.

Centered between the two front teeth 14 of the second Pliers jaw 2, an additional tooth 15 is attached.
  • This additional Tooth 15 projects over the two front teeth, which can be reached thereby Effect will be described in detail later. It is also between the rear Teeth 13 of this second jaw 2 an additional tooth 16 attached, which is not visible in FIG. 1, but in particular is taken from FIG. 17 can be.

They are kept Blocks 18 in the receiving pockets 23 in each case on the end faces 25 thereof Stop surfaces 26 abut. These stop surfaces 26 are on the one hand through the rear and front teeth 9 and 10 of the first jaw 1 or 14 and 15 of the second jaw 2 formed during the stop surface 26, which lies in the area of the joint 3, on the first jaw 1 or the second jaw 2 is formed.
  • the first cutting elements 17 forming blocks 18 in a simple manner in the jaw 1 or 2 used and by screwing the rear teeth 9, 13, or front teeth 10, 14 attached to the corresponding jaw 1 or 2 become.
  • a replacement of these blocks 18 can thus be carried out very quickly only the rear tooth 9 or 13 has to be removed become.
  • the blocks 18 of the first jaw 1 and the second jaw 2 are identical. You can thus freely among each other be replaced. This is a confusion when inserting the Blocks 18 in the jaws 1 and / or 2 excluded, a different Wear and tear can be compensated for by mutual exchange become.
  • FIGS. 3-5 The cutting process with these first cutting elements 17, the formed by blocks 18 is shown in FIGS. 3-5.

  • the reinforcing iron 27 lies first on the domes 31 of the cooperating blocks 18, like this 4 can be seen.
  • the reinforcing iron 27 is thereby held before the cutting edges 30 begin their cutting process. This will avoid that when the concrete crusher is closed further, the reinforcing iron 27 can be drawn into the cutting gap.
  • the on the Block 18 forces are cheaper, the cutting process, as shown in Fig. 5, is done in an optimal manner, since that to be cut Reinforcing iron 27 does not have the tendency to become jammed in the cutting gap which in turn would tend to expand. As a result, the cutting edges 30 are optimally stressed, the service life the first cutting elements 17 is extended.
  • each block 18 equipped with a guide rib 32 in the area of the convex surface 22, which engages in a groove 33 in the respective receiving pocket of the first Pliers jaw 1 and the second pliers jaw 2 is molded. This will an optimal mounting of the blocks 18 in the corresponding pockets the first jaw 1 and the second jaw 2 received.

  • these plates 21, which are the second cutting elements 20 form can be exchanged in a simple manner. Since the plates 21 are symmetrical, they can also be rotated so that the one or the other of the cutting edges 36 is in use.
  • the reinforcing bars 27 are pushed into the indentations 39, and then clamped by the side surfaces 35 as shown in FIG. 7 is.
  • the reinforcement bars 27 are closed the cutting edges 36 are cut, the forces acting on the plates 21 which want to pull the plates together.

  • the additional tooth 16, which is centered between the rear teeth 13 of the second jaw 2 is located and protrudes above this, also presses on the concrete slab 41. As can be seen from Fig. 10, this causes a bending effect on the concrete slab generated, the concrete begins to break under the bending forces that occur, as shown schematically in Fig. 10.
  • the closing movement of the concrete crushing tongs continues as 13 and 14, the concrete breaking process, which in particular through the rear teeth 9 and 13, through the front teeth 10 and 14 and through the additional teeth 15 and 16 of the first jaw 1 and the second jaw 2 was almost completed.
  • the first cutting elements 17 and the second cutting elements 20 have been little involved in the concrete crushing process and are therefore spared.
  • the wedge shape of the teeth now causes the reinforcing iron to the area of the first cutting elements 17 is pressed, as shown in FIG. 13 is shown. When closing the reinforcing iron 27, the are located in the area of the first cutting elements 17.
