Definitions

  • the invention relates to an access system according to the preamble of claim 1.
  • Such access systems are used in particular on buildings with a constant or variable circular floor plan, for example on chimneys, which act as circular cylinders or truncated cones, or on telecommunication towers, which act as rotational paraboloids, or cooling towers, as rotational hyperboloids are designed or similar structures.
  • the access systems can be used, for example, to carry out concrete renovations or on steel structures to renew the anti-corrosion protection.
  • the known access systems have a working platform, in particular made of light metal, which can be moved up and down on special cables on driving ropes.
  • an uppercarriage (as is known, for example, from DE-U-18 668 76) which can perform a circular drive.
  • the work platform is attached to the superstructure by means of travel and guide ropes.
  • the known access systems also have tensioning ropes that are tensioned and thus fix the working platform in its position in the event of wind and secure it against oscillation both radially and tangentially. These tension cables are attached to brackets on the base that can be moved on rails.
  • the pretensioning force required for safe operation essentially depends on the height between the uppercarriage and the lower rails. Increased pretensioning forces are required, for example, for access systems for the inner wall surfaces of cooling towers. In this case, an additional contact pressure of the work platform must be generated in the areas that are offset to the outside from the upper attachment point.
  • Such a work platform is known from DE-OS 20 14 102, which has blowers, by means of which a vacuum zone is created between the suspended platform and the wall in order to hold this working platform on the wall by suction.
  • these blowers can be used to blow against the wall in order to create a compressed air cushion between the wall and the work platform, which holds the work platform at a certain distance from the wall.
  • DE-G 85 31 513 U1 describes an auxiliary construction in which at least one turbomachine generating a thrust force is mounted on or in the work platform, the pressure side of which is arranged on the side of the work platform facing away from the wall and is directed away from the wall.
  • the invention has for its object to design the work platform of such an access system so that the known tensioning ropes are omitted, but the work platform is nevertheless reliably pressed against curved surfaces on the structure, can be moved in two mutually perpendicular directions and reliably prevents oscillation and swinging out becomes.
  • the magnetic plates which are articulated on both sides of the working platform by means of cantilevers, hold the working platform securely to building surfaces made of reinforced concrete or steel.
  • the magnetic plate is equipped with ball rollers, by means of which it is guided on the building surface.
  • the magnetic plate is advantageously designed as a permanent magnet. No feed is required in this embodiment.
  • an electromagnet and a power store are installed in the magnetic plate.
  • the power generator for the electromagnets is located in the work platform.
  • the power store or the power generator can advantageously also feed the drives for vertical and circular travel.
  • the arrangement of the power generator or power storage in the work platform has the particular advantage of being able to operate the access system without a supply cable.
  • the magnet strength depends on the respective working conditions. It is determined by the building parameters such as height, shape or material.
  • the work platform is equipped with swivel castors that can be placed sideways in horizontal travel and long ago in vertical travel. If the access system is used for curved building shapes, for example on cooling towers, an inclination compensation is carried out. In extreme building shapes, the castors are advantageously designed as ball casters.
  • the work platform 4 of an access system shown in FIG. 1 is only suspended from the superstructure 2 by means of the driving and guide ropes 3, which is mounted on the upper edge of a cylindrical structure. In a known manner, this superstructure 2 can make a circular trip around the edge of this cylindrical structure.
  • the work platform 4 has an articulated boom 5 on each side, which carries a magnetic plate 6 at each end.
  • the work platform 4 is held securely on the building surface 1 by means of the magnetic plates 6.
  • Each magnetic plate 6 is guided on the building surface 1 by means of ball rollers 7.
  • the work platform 4 has castors 8 which, as indicated schematically in FIG. 4, are placed transversely during horizontal travel. When moving vertically, these castors 8 are rotated by 90 °.
