Definitions

  • the invention relates to a demolition device for breaking and crushing, in particular, reinforced concrete, consisting of two scissor-like interacting, hydraulically driven jaws, one of which has at least two, the other at least three working bars with crushing teeth, all of which are arranged parallel to one another and alternately in the closed position mesh.
  • Demolition devices of the aforementioned construction are primarily used on site to demolish any type of structure, technical systems, etc.
  • reinforced concrete is a very heterogeneous material made of extremely hard aggregates, cement and steel reinforcement. While the steel reinforcement can be separated comparatively easily with scissors, the concrete has to be reduced primarily by sheer compressive forces. The compressive forces must be applied in an order of magnitude higher than the compressive strength of the concrete. This crushing the concrete must also be done first before the steel reinforcement is exposed and can be separated.
  • Devices of a similar design are then used to separate the steel reinforcement, but their jaws are equipped with cutting tools (DE-A-27 22 258, 36 23 061).
  • the jaws or the cutting tools attached to them are arranged with respect to one another in such a way that, when the jaws close, they shear past each other and cut the reinforcement by a cutting movement.
  • the object of the invention is to provide an education with which concrete can be crushed effectively and in an energy-saving manner. It should also be possible to break and shred reinforced concrete of any quality and it should finally be possible to use the demolition device on site without endangering the excavator's stick.
  • the crushing teeth lie in different planes perpendicular to the closing movement of the jaws and are consequently effective at different times.
  • the two outer work bars on the jaw with the greater number of work bars take effect together with the work bars on the other jaw.
  • the component to be broken off or shredded is built between the two outer work strips considerable bending forces that lead to breakage.
  • the work bars on the jaws with the smaller number have passed the outer work bars of the other jaw, the inner work bars and thus primarily pressure forces are effective. So it is a multi-stage breaking process through combined bending and compressive forces.
  • the one jaw has three, the other jaw four work strips, of which the two middle ones are set back, while in the other jaw the middle work strip is set forward in relation to the two outer ones.
  • the breaking teeth on the two outer working strips of one jaw and the breaking teeth of the middle working strip on the other jaw are effective.
  • the middle part of the area of the demolition material lying between the jaws is stressed, namely between the middle bar of one jaw and the two inner work bars of the other jaw.
  • the outer parts of the area between the jaws are acted upon between the outer work strips of both jaws.
  • a conventional scrap shear can then be used to separate the reinforcement.
  • a further preferred embodiment of the invention is characterized, however, in that cutting tools are arranged on the sides facing one another in the closed position of at least two adjacent working strips of the two jaws between the crushing teeth, which are set back in the direction of the closing movement with respect to the crushing teeth and towards the end run past each other shearing the closing movement.
  • the cutting tools are preferably arranged on the middle of the three working bars of one jaw and on one of the two middle working bars of the other jaw, so that the cutting tools only become effective when all of the breaking teeth have become effective. This is the best way to protect the cutting tools against the concrete.
  • the cutting tools can also be provided on the mutually facing sides of all work strips.
  • a further preferred embodiment is characterized in that the crushing teeth on the work bars of at least one jaw are pointed and a rounded depression is arranged between the flanks of adjacent crushing teeth of these work bars, and that the effective shear edge of the cutting tools roughly affects the deepest point of the depression.
  • breaking teeth have roughly linear breaking edges transverse to the direction of movement of the jaws with tooth flanks falling off to both sides.
  • breaking teeth inevitably displace the steel reinforcement outwards into the recesses on the one jaw, so that controlled cutting conditions are available, as with special scissors.
  • the crushing teeth are advantageously arranged so that they can be replaced on the work bars.
  • the crushing teeth rest with a back facing the work bar, a flat abutment on the work bar and have at least one guide part engaging in a recess on the work bar abutment, by means of which they are fastened to the work bar.
  • the crushing teeth are positioned correctly on the one hand, and on the other hand, the forces from the crushing tooth are introduced into the jaws.
  • the crushing teeth can be easily replaced with the corresponding wear in the embodiment according to the invention.
  • the cutting tools are also interchangeably arranged on the work strips so that they can be replaced when worn.
  • the training is made so that the cutting tools are designed as square cutting plates, which are attached to the center of the work strips and whose all edges form sheared edges.
  • the cutting tools are designed in the manner of indexable inserts. All longitudinal edges on both sides of the cutting plates act as shaving edges, so that each side has four shearing edges, that is to say the cutting plate has a total of eight shearing edges.
  • the shaving edges on one side become effective one after the other simply by turning the cutting plate, while after turning the cutting plate the shaving edges on the other side can be used.
  • the cutting inserts are preferably arranged recessed in the work strips so that on the one hand they can be positioned correctly and on the other hand they can better absorb the forces.
  • the crushing teeth are arranged in such a way that the common plane of the crushing edges of the crushing teeth of opposing work bars does not intersect the axis of the scissor joint.
  • the common plane of the breaking edges of the breaking teeth and the shearing edges of the cutting tools on opposite working strips is preferably offset in the same direction with respect to the axis of the scissors joint.
  • a constructively and in terms of strength particularly favorable design is characterized in that the work strips are clamped at their inner end with the interposition of spacer rings on an axle bolt of the scissor joint of the jaws and are rigidly connected to one another at their outer end by a connecting strip.
  • the stability is further improved in accordance with a further exemplary embodiment in that the work strips are approximately triangular in shape, the scissor joint being arranged in the region of one, the connecting strip in the region of a further and a further connecting piece in the region of the third corner.
  • the jaws of the demolition device are driven hydraulically.
  • An advantageous embodiment provides that in the region of the third corner of one jaw a hydraulic cylinder engages, which is supported on an extension having the other jaws and extending beyond the scissor joint.
  • the extension of one jaw is expediently designed as a housing and is set up for connection to the arm of an excavator.
  • This design has the advantage that the most sensitive functional part of the demolition device, namely the piston rod, is always protected in the housing and cannot be damaged by external forces, falling parts or the like. Because the jaws are not driven by the bucket-tilt cylinder forth, the demolition device can assume any position relative to the dipper stick, so that the demolition device can attack in any location on the structure, in particular on-site, even without precise starting of the excavator.
  • a rotary connection and a rotary motor is provided between the housing and the dipper stick of the excavator, the turning axis of which is approximately perpendicular to the axis of the scissor joint.
  • the demolition device can therefore be rotated in any position in relation to the excavator's dipperstick in order to enable an effective attack on the structure or component.
  • the demolition device according to FIGS. 1 and 2 has a housing 1, which is formed from two side walls 3 and a wall connecting them on the side 2 and is open on the side opposite the side 2.
  • a connection part 4 is arranged on the upper part of the housing 1 via a rotary connection, in which a rotary motor 5 for rotating the demolition device about the axis 6 is arranged.
  • the demolition device has two jaws 7, 8, which are essentially triangular.
  • the jaw 8 is rigidly connected to the housing 1, while the other jaw 7 is articulated on the scissor bearing 9.
  • the jaws 7 can be pivoted from the open position shown in FIG. 1 into the closed position according to FIG. 2 by means of the hydraulic cylinder 10. During this movement, the piston rod 14 of the hydraulic cylinder 10 is always inside the housing in which the hydraulic cylinder 10 engages the joint 12. The hydraulic supply takes place in the area of the bearing 11 via corresponding channels in the piston rod 14.
  • the pivotable jaw 7, as can be seen from FIG. 3, has three parallel working strips 15, 16 and 17, the fixed jaw 8 four parallel parallel working strips 18, 19, 20 and 21. All work strips are equipped with a plurality of crushing teeth 22 and 23 arranged one behind the other in the direction of extension of the jaws.
  • the crushing teeth 22 of the jaw 7 and the crushing teeth 23 of the jaw 8 each lie on common radii with respect to the pivot bearing 9, so that they act directly against one another during the closing movement.
  • the crushing teeth are triangular and have a cutting edge 24 running perpendicular to the plane of movement of the jaws 7, 8, from which the flanks 25 drop towards the jaws.
  • the triangular breaking teeth are interchangeably arranged on the jaws.
  • the breaking teeth 22 on the jaws 7 and the breaking teeth 23 on the jaws 8 are not arranged with their cutting edges in the same plane.
  • the breaking teeth 23 on the two outer working strips 18 and 21 of the jaw 8 lie in one plane, while the breaking teeth 23 on the two intermediate working strips 19, 20 are set back.
  • the crushing teeth 22 on the middle working bar 16 of the jaw 7 are offset from the crushing teeth 22 of the two outer working bars 15, 17 of this jaw.
  • the breaking teeth 22 on the middle working bar 16 of the jaw 7 and the breaking teeth 23 on the two outer working bars 18, 21 of the jaw 8 are effective first. The component clamped between the jaws is therefore subjected to pressure and bending.
  • the working strips 15, 16, 17 of the one jaw 7 and the working strips 18-21 on the jaw 8 are clamped to one another on the pivot bearing 9 via spacer rings, while at the outer end they are rigidly connected to one another via connecting strips 29.
  • the work strips are, as already indicated, triangular and in the area of the third corner at 30 again clamped together by means of a bolt and spacer rings passing through a sieve.
  • the middle work bar 16 on the jaw 7 and one of the middle work bars on the jaw 8 - in the embodiment shown the work bar 19 - are equipped with cutting tools 31, 32 which are designed as square cutting plates.
  • the cutting plates 31, 32 are sunk into corresponding recesses on the work strips 16 and 19 and fixed by means of a releasable fastening means 33.
  • Each edge 34 of each cutting tool 31, 32 forms a shear edge, so that a total of eight shear edges are available by turning the cutting plates 31, 32 and by turning.
  • the cutting tools 31, 32 are, as I said, arranged on the middle work strips 16 and 19, which thus become effective when the jaws 7, 8 are closed. They sit on the mutually facing sides of the two work strips below the breaking teeth 22 and 23.
  • the shear edges 34 of the cutting tools 31 on the work bar 16 of the jaw 7 practically form the tooth base between the breaking teeth 22.
  • the tooth base therefore runs linearly.
  • rounded recesses 35 adjoin the flanks 25 of the crushing teeth 23.
  • the cutting tools 32 on the work bar 19 of the jaw 8 touch the recess 35 at their deepest point with their shear edge 34.
  • the common plane of the effective shear edges 34 of the cutting tools 31, 32 is eccentric to the pivot bearing 9.
  • the common planes of the breaking teeth 22, 23 of the different ones Work strips in a position offset to the pivot bearing 9 on the same side.
