Definitions

  • the invention relates to a facade elevator with a movable on a building roof on rails carriage, which carries two pivotable about vertical axes boom over which lifting cables are guided, on which a gondola hangs.
  • Facade lifts of this type are used for the maintenance and cleaning of facades and windows, in particular of very tall buildings.
  • one or more operators enter the gondola, which is then pivoted by the cantilevers in front of the outside of the building and moved with the lifting cables along the facade in the vertical direction and by moving the carriage on the rails in the horizontal direction.
  • the brackets can be pivoted about horizontal axes and are arranged at such a distance from one another that the gondola can be guided between the two brackets when swinging out or in.
  • the gondola hanging in front of the facade is always in the same plane as the car, orthogonal to the facade.
  • the facades can be used sufficiently for maintenance and cleaning purposes, but difficulties arise in the corner areas of the building, which often cannot be reached by the gondolas or the operators located therein, because it is considered the rail guidance on the roof of the building is not possible to guide the nacelle horizontally around a corner of the building.
  • you can help yourself by placing the entire structure on a slewing ring and rotating it around a horizontal axis; Although this improves the positioning of the gondola, it rarely leads to satisfactory results.
  • the object of the invention is to improve the possible uses of a facade elevator of the type described and, in particular, to improve driving on the corner areas of building facades.
  • the gondola can be brought into a position in which it is arranged orthogonally to the building facade.
  • the length difference of the cantilevers in particular can correspond to the distance of the lifting cables on the nacelle.
  • the facade elevator according to the invention to drive over corner areas of building facades without a special rail guide having to be provided and / or the arms having to be particularly long.
  • the rest position of the gondola of the facade elevator according to the invention placed on the building roof is in the direction of movement in front of or behind the carriage.
  • the gondola can also be placed in front of the superstructure parallel to the direction of movement, as in known facade elevators.
  • the static conditions in the facade elevator according to the invention are more favorable because on special supports, e.g. Lift cylinder arrangements in the known facade elevators, can be dispensed with, and the cantilevers are mounted in simple pivot bearings with a vertical pivot axis, which in particular absorb the vertical forces, so that there is greater security against the gondola falling. Stability is also improved, since the balance of gravity between work position and rest position is approximately the same.
  • Each boom can have its own swivel drive. If, according to a preferred embodiment of the invention, the swivel drives are actuated independently of one another, the positions of the arms can be adjusted independently of one another. This allows e.g. move the nacelle to a position where it is no longer parallel, but at an angle to the building facade. This can also be advantageous when working on corner areas of the building facade. On the other hand, it is possible to change the outreach of the outrigger beyond the building facade and thus the distance of the nacelle from the building facade by means of synchronous or diverging boom movement.
  • the gondola can be moved almost without restriction if, according to a further proposal of the invention, the two arms are arranged at different heights and / or have different inclinations. Then the booms can also be brought into positions where they cross, and the gondola can change its operational position practically continuously, without the car having to be moved on the roof of the building.
  • booms of different lengths which also differ Lich arranged high, the possibility that when the gondola is parallel to the facade in the right or left offset to the superstructure, the distance to the facade can be changed and that this possibility is also given when the gondola is transverse to the facade.
  • aisles that are narrower than the usual width of the gondola can be used advantageously, even if they are behind the facade.
  • the arms can also be pivoted about a horizontal axis.
  • the distance between the pivot axes of the boom can be adapted to the particular circumstances. It can be larger or smaller than the distance between the hoisting ropes on the nacelle, and an embodiment is also possible in which the arms can be pivoted about a common pivot axis.
  • the facade elevator shown in Figure 1 has a carriage 1, which can be moved in a manner known per se with a drive 2 on rails 3, which are laid on supports 4.
  • the supports rest on the roof 5 of a building with a parapet 7, the facade 6 of which is to be serviced and / or cleaned.
  • the carriage 1 has two bearings 8, 9 with a vertical bearing axis for pivot pins 10, 11 held therein, two brackets 12, 13, over which lifting cables 14, 15 are guided, the ends of which are attached to the sides of a nacelle 16.
  • the booms 12, 13 are assigned swivel drives, not shown, which are accommodated in the carriage 1 and which, if appropriate, can be actuated independently of one another.
  • the lifting ropes 14, 15 are guided into the carriage 1 and wound there on driven drums, not shown.
  • the inclination of the arms 12, 13 with respect to the horizontal is approximately 30 °.
  • the inclination and length of the arms 12, 13 are set up in such a way that the nacelle 16 can easily be lifted over the parapet 7.
  • FIG. 3 shows the so-called rest position of the arms 12, 13, in which the nacelle can be set down in front of or behind the carriage 1 in the region of the rails 3 in the direction of movement of the carriage. This operating position corresponds approximately to the operating position shown in Figure 2.
  • the gondola 16 can also be brought into the corner region 17 of the facade 6 with a corresponding pivoting position of the arms 12, 13, although the rails 3 for the carriage 1 do not extend into this region, but in Arch 18 are led away from the corner region 17. It goes without saying that the gondola 16 can be brought closer to the facade or further away from it by separately actuating the pivot drives of the arms 12, 13. In particular, in the exemplary embodiment according to FIG. 3, by pivoting the arm 12 clockwise, the nacelle 16 can be pivoted closer to the corner area and partially pivoted around the corner.
  • the boom 12, 13 in turn have different lengths.
  • Their bearings 8, 9 are, however, arranged at a distance which is smaller than the distance of the lifting cables on the nacelle 16, i.e. smaller than the length of the nacelle 16.
  • the bearings 8, 9 practically lie side by side.
  • the boom support alone provides mobility that is otherwise only possible with additional elements (e.g. slewing ring on the superstructure).
  • a corresponding operating position is indicated by dash-dotted lines in Figure 4.
  • the boom 12, 13 have different lengths, ie the boom 12 is shorter than the boom 13.
  • the gondola 16 is at a certain distance from the facade 6.
  • the boom 12 extends essentially orthogonally to the facade 6 in the projection shown. If the nacelle 16 is to be brought further to the facade 6 without its position relative to the facade 6 being changed, then the swivel drives of the arms 12, 13 are actuated in such a way that that the boom 12, 13 assume the operating position shown with dash-dotted lines.
  • This position which can be changed parallel to the facade 6, can also be offset laterally if the arms 12, 13 are moved in the same direction, but with different swivel angles (arm 12 is smaller, arm 13 is larger).
  • the booms 12, 13 are ge relative to each other spreads, the hoisting ropes 14, 15 also being spread.
  • the gondola 16 is brought closer to the facade 6.
  • the gondola 16 can also be pivoted through 180 ° and brought into an operating position, for example, which is indicated by dashed lines in FIG. 5.
  • facade elevator shown all types of facades, in particular facades with offset sections, half-open shafts and the like, can be used without difficulty.
  • the corner areas of facades can be easily reached with the facade elevator shown.
