Definitions

  • the present invention relates to a demolition tool and a method for demolition of rock.
  • Rock within the meaning of the invention is both natural rock and artificial rock, such as concrete.
  • Rocks are currently usually broken down by blasting, by hydraulic hammer or by the Bohr-Spalt technique.
  • the drilling and slitting technique rows of holes are drilled in the rock to be excavated, into which are subsequently introduced wedge-shaped splitting tools to split the rock.
  • the EP 2 489 823 B1 describes an apparatus and method for fracturing solid materials, such as rock and concrete, using the Bohr-Spalt technique.
  • the device comprises a carriage with a work head which can be displaced transversely on the carriage along a first axis and which is rotatable about a second axis relative to the carriage.
  • On the working head a drilling device and a splitting device are mounted, which are alternately brought into working position.
  • the DE 10 2013 206 565 B4 shows a hydraulically operated splitting device in the form of a wedge lance, which uses the Bohr-gap method for the degradation of rock.
  • This mining machine comprises means for producing horizontal slots in the material to be excavated, means for producing a vertical slit which intersects the horizontal slits to form columns, and picking means arranged between the means for producing the horizontal slits to cut off portions of the column.
  • the demolition with excavator tillage is economical and reasonable only up to a uniaxial compressive strength of the rock of 60 MPa.
  • Excavator tillage mills are therefore mainly used for the degradation of soft and medium-hard rock, such as limestone or gypsum.
  • the object of the present invention is therefore a demolition tool and a method for demolition of rock to provide, which allows a more effective demolition of rock while working shake-free. Slippage of the demolition tool during breakage should be effectively avoided.
  • the piece size of the broken fragments should be controllable in order to adapt them in particular to the size of a crusher.
  • the demolition site should still have a largely flat surface as possible without further post-processing.
  • the demolition tool according to the invention serves to demolish rock.
  • several slots are incorporated, between whichShierides material stops.
  • two or more substantially parallel slits of a predetermined depth and a predetermined distance from each other are introduced.
  • the slots can also run at an angle to each other, if this is advantageous at the termination point.
  • the demolition tool is insertable into each of the slots to break the rock between the slots by establishing transverse forces acting substantially perpendicular to the slot planes.
  • the demolition tool has a base body with a first free end portion and an opposite second end portion. The second end portion is formed to exert a compressive force on a second wall portion of the slot. The second wall portion extends from a bottom of the slot opposite the bottom.
  • the main body is fixedly connected at its second end region with a mounting bracket for mounting the demolition tool to a movable support arm of a construction machine, in particular an excavator.
  • the Demolition tool can preferably be attached to the same construction machine, to which a cutting wheel used for milling the slots can be grown, in exchange with this.
  • the construction machine is preferably equipped with an automatic quick-change device.
  • the support arm of the construction machine or excavator applies the necessary forces to move the demolition tool to the desired position and to move it into the slots in the rock.
  • At least one scoring tool is arranged at the first end region of the main body, which serves for introducing a parallel to the bottom of the slot extending scratch in the first, lower-lying wall portion of the slot.
  • the introduced scratch extends only over a defined depth into the wall section, preferably less than half the thickness of the wall section.
  • the Ritz thus does not cut through the rock completely, so that the wall section initially stops. There is no cutting of the rock in the region of the first wall section into the adjacent slots. This saves cutting performance and enables the targeted breaking off of the material at the desired time.
  • Via the second end region a compressive force is exerted on the second wall section of the slot, which then causes the material to break off in the region of the scribe.
  • the demolition tool according to the invention has several advantages compared to the known demolition tools. Thus, larger amounts of rock can be broken efficiently with the demolition tool according to the invention. In addition, the demolition is shake-free. This is a significant advantage compared to blasting.
  • the scratch produced by the scoring tool creates a predetermined breaking point which ensures a controlled breaking of the rock. At the bottom of the slot creates a relatively smooth fracture surface.
  • the demolition tool comprises a plurality of scoring tools.
  • Several scribing tools allow for quick and consistent scoring.
  • An advantageous embodiment uses a demolition tool with a cylindrical base body, which in each case has an elliptical cross-sectional widening in the first and the second end region.
  • Two opposing first cross-sectional areas of the elliptical cross-sectional widening have a larger diameter than two opposing second cross-sectional areas of the elliptical cross-sectional widening.
  • the at least one scoring tool arranged in the first end region is arranged on one of the first cross-sectional regions.
  • a preferred embodiment further utilizes a plurality of scoring tools in each of the first two cross-sectional areas.
  • the diameter of the second cross-sectional areas corresponds approximately to the width of the slots, wherein the diameter is to be selected slightly smaller in order to introduce the demolition tool in the slot can.
  • the demolition tool can be inserted either from above or laterally into the slot.
  • the demolition tool inserted into the slot is subsequently rotated, with the at least one scoring tool coming into contact with the first wall portion and creating the score.
  • a compressive force is applied by the second end portion to the second wall portion to break the material between the slots.
  • This embodiment of the demolition tool is particularly suitable for compact and hard rock.
  • the demolition tool has, according to an alternative embodiment, a base body with a convexly curved longitudinal side.

  • the first end region of the main body is preferably equipped with a plurality of scoring tools, which preferably extend as an extension of the first end region from the first end region.
  • the first end portion of the demolition tool has a slightly greater width than the slot. The so executed demolition tool is introduced laterally with its first end portion in the slot and moved linearly through the slot.
  • the scoring tools come into contact with the first wall section and generate the score.
  • the rock between the slots is broken by the pressing force exerted by the second wall section.
  • This pressure force acts due to the increasing in the longitudinal direction of the body cross-section of the body.
  • This embodiment can preferably be used in medium-hard or fissured material.
  • the second end region which is closer to the mounting bracket than the first end region, has a breaking tool for exerting a compressive force on the second, less deeply situated wall section of the slot.
  • the due in the longitudinal direction of the body Increasing cross-section of the body on the second wall portion acting pressure force is amplified by the arranged in the second end region of the body crusher.
  • This embodiment has the advantage that slippage of the demolition tool through the slot can be effectively prevented by the longitudinally widening cross section of the base body and by the pressure force exerted by the breaking tool.
  • a preferred embodiment utilizes a breaking tool designed as a breaking wedge.
  • the crushing wedge is partially wider than the base body formed. It has proved to be favorable to carry out the broad side of the crushing wedge about 30% to 40% wider than the main body, with no restriction to the said range of values, wider or narrower crushing wedges are quite possible.
  • the crushing wedge is preferably hydraulically driven by the construction machine, for example by a bucket cylinder of the excavator.
  • the compressive force exerted by the breaking wedge acts in addition to the compressive force generated by the basic body and ensures that the rock is broken and completely detached from a mining wall.
  • the crushing wedge is preferably provided on its outer circumference with a plurality of plates, which serve for stiffening and are preferably exchangeable as wearing parts. Designs with four plates, which extend on both sides of the Brechkeilspitze in the direction of the body, have proven to be favorable.
