Definitions

  • the invention relates to a device for breaking off chimneys made of masonry, concrete or reinforced concrete, in particular of high chimneys, by means of a demolition tool which gradually removes the chimney shaft from the chimney head to the chimney foot, e.g. is already known from patent application EP-A-0133630.
  • the invention has for its object to provide a device which allows chimneys and in particular tall chimneys to be broken off by machine with optimum safety and in a rational or economical manner.
  • the generic device is characterized by a work platform that can be attached to the mouth end of the chimney shaft and suspension devices distributed over the circumference of the stage, each with at least one vertically guided lowering piston that can be locked in different height positions, in that the work platform is suspended in the interior of the chimney shaft and that a suspension arm is pivotally mounted on the upper piston end of the lowering piston, which engages over the chimney wall in the pivoted-out position.
  • the invention further teaches that the work platform has supporting devices distributed over the circumference of the stage with support arms which can be adjusted against the inside of the chimney.
  • the invention is based on the knowledge that an excavator with a demolition tool can then be used with sufficient freedom of movement and optimal safety for demolition of chimneys if a work platform is installed for this excavator, which is gradually lowered from the chimney head to the chimney base in accordance with the progress of demolition can be.
  • a work platform can be lifted to the level of the chimney mouth in the same way as the excavator by means of an approved conveyor scaffold and hung there in the chimney shaft.
  • the work platform is suspended from the chimney wall using the all-round suspension devices. Then the lowering pistons are extended, so to speak, ie the work platform hangs at the lower end the lowering piston and the suspension arms overlap the chimney wall.
  • the suspension arms are swiveled in or back in individually and one after the other, so that the chimney wall can be demolished shortly above the level of the work platform.
  • the lowering piston in question is then moved down or retracted by the extent of the demolition progress and the relevant suspension arm is pivoted out again, so it then overlaps the chimney wall at the demolition point that has migrated downward.
  • the work platform which regularly has a polygon-like circumference, is moved on each suspension arm or lowering piston, so that finally all working pistons with their suspension arms are retracted by the degree of progress of the dismantling or moved down.
  • the extent of the demolition progress corresponds to the maximum piston stroke.
  • the invention provides that the support devices are connected in a radial extension to the suspension devices and the suspension devices with the support devices with the interposition of cantilever arms in the radial direction can be moved forward or can be seized.
  • the cantilever arms can be designed as profile supports, rack and pinion drives or cylinder piston arrangements with screwable connecting flanges.
  • profile beams can be successively connected to one another via their connecting flanges and inserted between the suspension devices and the working platform.
  • the suspension devices each have a guide tube flanged directly to the working platform or to an intermediate cantilever arm in a vertical orientation for the lowering piston which is height-adjustable and lockable in the guide tube, and that the guide tube and the lowering piston are in predetermined height distances aligned cross holes to the have locking bolts. In this way, the extent of the demolition progress can vary over the height of the piston stroke, so that the working platform only has to be lowered after several demolition steps that have taken place over the chimney circumference.
  • the guide tube is designed as a rectangular tube and the lowering piston as an I-profile and longitudinal guides, for example ball guides or roller guides, are arranged as ladder-shaped flat cages or roller carriages for the lowering piston.
  • the lowering piston expediently has a footplate at its lower end as a stop for the guide tube and consequently the work platform, as well as suspension eyes at its upper end.
  • the work platform can be attached to a conveyor frame in the chimney mouth.
  • the vertically guided lowering piston carries two horizontal bearing cheeks at its upper end and the suspension arm is pivotally mounted on a horizontal bearing pin between these bearing cheeks and can be locked in a horizontal position by means of locking pins which can be inserted into aligned cross holes on one or both sides of the bearing pin.
  • the bearing cheeks and the suspension arm can consist of U-profiles. Each suspension arm can at its resting end have a height-adjustable support plate in order to achieve perfect support on the demolition surface of the chimney shaft.
  • the inner ends of the suspension arms and the guide tubes are connected to one another in the region of their inner connecting flanges via chain or cable pulls and thereby the working platform by means of Chain or cable pulling devices can be lowered on the suspended lowering pistons. Lowering the platform in this way is necessary before each demolition cycle. The lowered working platform then rests on the base plates of the lowering pistons and is supported against the inner wall of the shaft.
  • each guide tube is surrounded by a double collar with a connecting flange for the working platform or the intermediate cantilever arm and one or two support arms are pivotably mounted in a horizontal plane between the two collars and can be fixed in a position against the inner chimney wall, e.g. by means of a chain hoist or linkage connecting both support arms, so that the support arms cannot swing out independently and the support is thereby lost.
  • the support arms can have support plates which can be pivoted or articulated at the end.
  • the figures show a device for breaking off chimneys made of masonry, concrete or reinforced concrete, in particular free-standing chimneys of great height.
  • the chimney is broken off by means of a successive removal of the chimney shaft 1 from the chimney head to the chimney foot Demolition tool 2, which is attached to the cantilever arm 3 of an excavator 4 according to the embodiment.
  • a work platform 5 is suspended in the chimney shaft 1 at its mouth end, specifically with suspension devices 6 distributed over the circumference of the stage, each with at least one vertically guided lowering piston 7, which can be locked in different height positions, and a suspension arm 8 pivotably mounted at the upper piston end, which in the pivoted-out position Spread over chimney wall.
  • the work platform 5 also has support devices 9 distributed over the circumference of the stage, with support arms 10 which can be adjusted against the inside of the chimney.
  • the support devices 9 adjoin the suspension devices 6 in a radial extension.
  • the suspension devices 6 can be advanced or pre-attached with the support devices 9 with the interposition of cantilever arms 11 in the radial direction in order to always allow adaptation to the chimney diameter which increases from the chimney head to the chimney foot.
  • the working platform 5 has a polygon-like circumference, consists essentially of cross-beam-shaped profile beams 12 and a platform 13 carried by them.
  • the cantilever arms 11 are designed as profile beams with screwable connecting flanges 14.
  • the working platform 5 and the suspension devices 6 have such connecting flanges 14.
  • Catwalks 15 can be fastened on the cantilever arms 11.
  • Safety nets 16 can be suspended between the cantilever arms 11, which is only indicated.
  • the suspension devices 6 each have a directly on the work platform 5 or on an intermediate cantilever 11 in a vertical orientation flanged guide tube 17 for the lowering piston 7 which is height-adjustable in the guide tube and lockable at different heights.
  • the guide tube 17 and the lowering piston 7 have aligned cross bores 18 for inserting locking bolts at predetermined height intervals.
  • the guide tube 17 is designed as a rectangular tube and the lowering piston 7 as an I-profile. Roller guides 19 for the lowering piston 7 are arranged in the guide tube 17.
  • the lowering piston 7 has a base plate 20 at its lower end and suspension eyes at its upper end. In the lowered position, the working platform 5 rests on the base plates 20 of the lowering piston 7.
  • Each of the distributed lowering pistons 7 carries two horizontal bearing cheeks 21 at its upper end. Between the bearing cheeks 21, the suspension arm 8 is pivotably mounted on a horizontal bearing pin 22 and can be locked in a horizontal position by means of locking pins which can be inserted into aligned cross bores 23 on one or both sides of the bearing pin 22, when the suspension arm 8 overlaps the chimney wall and the working platform 5 is suspended with the lowering piston 7 interposed.
  • the bearing cheeks 21 and the suspension arm 8 consist of U-profiles.
  • Each suspension arm 8 has a height-adjustable support plate 24 at its resting end for adaptation to the respective demolition surface.
  • each Guide tube 17 is surrounded by a double collar 26 with a connecting flange 14.
  • one or two support arms 10 are pivotally mounted in the horizontal plane and can be fixed in the position against the chimney inner wall, for example by means of a chain hoist 27 or linkage connecting the two support arms.
  • the support arms 10 are pivoted apart.
  • the support arms 10 have pivotable or articulated support plates 28 in order to achieve perfect support against the chimney inner wall.
  • a chimney is demolished as follows:
  • the excavator 4 begins its demolition work in the region of a suspension arm 8 which is pivoted back or in. After the demolition has taken place Over a predetermined height, which must not exceed the maximum piston stroke of the lowering piston 7, the suspension arm 8 in question is pivoted back into its starting position spanning the chimney wall. The lowering piston 7 in question is then automatically in the retracted position.
  • the lowering pistons 7 touch the ground. Ultimately, this also applies to the work platform.
  • cantilever arms 11 are increasingly used between the working platform 5 and the guide tubes 17 for the lowering pistons 7 with the support arms 10, so that the support arms 10 can always be positioned properly against the increasing chimney inner wall and for centering and movement-free support of the work platform 5.
  • substructures 31 which can be covered with carriages 30 can be connected to the cantilever arms 11 in order to achieve an expansion of the work platform 5 into the region of the chimney wall, so that the excavator 4 moves forward from the center of the chimney and can carry out demolition work from the outside with demolition tool 2 spanning the chimney wall.
  • use is on the catwalks 15 and safety nets 16 are dispensed with. This is only indicated in some areas in FIG. 6.
