Definitions

  • the invention relates to a facade elevator for walls with recessed parts with a suspension structure suspended on cables for a gondola rotatably mounted thereon about a vertical axis, the length of which is greater than its width.
  • Facade lifts are used for cleaning windows on buildings, for carrying out repairs and for checking facades.
  • the ropes on which the gondola hangs are generally guided via swiveling brackets to a carriage which can be moved on the building roof and which can be moved parallel to the facade.
  • the lift and undercarriage are controlled from the nacelle. Limit switches limit the lift of the facade lift up and down. After the work on the facade has been completed, the gondola can be lowered onto the roof of the building using the swivel arm.
  • the gondola is connected to the end of a support arm belonging to a pantograph guide.
  • the pantograph guide is in turn connected to a pivot bearing of the supporting structure.
  • recessed facade parts in particular windows, can also be reached from the gondola.
  • the well-known facade elevator is structurally complex and the control of the gondola is difficult.
  • the invention is based on a prior art as disclosed in DE-A-208660. It is a facade elevator with a frame-like support structure that has a horizontal floor crossmember on which the gondola is rotatably mounted.
  • the gondola must be at least shorter than the supporting structure, which thus determines the main dimensions of the facade elevator. In many cases, this proves to be unfavorable because the components of the supporting structure hinder work that is to be carried out from the nacelle. If the width of the supporting structure is also greater than the width of the gondola, the possible uses of this known facade elevator on walls with recessed parts are further impeded.
  • the invention is based on the object of constructively improving a facade elevator of the type described at the outset in such a way that the supporting structure no longer impedes the operation of the facade elevator and working from the gondola.
  • the supporting structure is a traverse suspended from the ropes on which the nacelle, which has a frame-like structure, is directly rotatably suspended, the frame-like structure of the nacelle arranged at the corners of the nacelle and one on whose free corners have a fixed roof structure, which is mounted on and under the crossbar.
  • the supporting structure which is designed as a simple traverse, can neither interfere with the operation of the facade elevator nor when working from the nacelle, and not even if, according to the preferred embodiment, the truss has a width which corresponds to the width of the nacelle or Corresponds to the width of the gondola roof. With the gondola hanging freely under the crossbar, work can be carried out in any operating position of the gondola without having to take the relative position of the crossbar into account.
  • recessed facade parts can be achieved by rotating the nacelle so that its longitudinal axis extends essentially orthogonally to the facade, the shorter side of the nacelle then being in front of the recessed facade part.
  • the inclination of the gondola due to one-sided weight loading when working on the facade remains low because the gondola is pivoted about a central axis of rotation.
  • Remaining angles of inclination can e.g. can be compensated for by carrying counterweights in the nacelle and arranging them accordingly.
  • a counterweight e.g. serve a water tank, which is required anyway when cleaning the window.
  • the traverse is also stored in a substantially rectangular plan and in the area of its corners on the ropes, i.e. is connected to a total of four ropes, the ropes can be loaded unevenly if the nacelle rotated by 90 ° C is loaded on one side.
  • the pivot bearing for the nacelle can be pivotally mounted on the crossbar about a horizontal axis. If necessary, the horizontal pivotability of the pivot bearing can be limited by stops.
  • At least the crossmember receiving the pivot bearing should have a width corresponding to the width of the gondola and a length which is greater than the length of the gondola, the pivot or pivot bearings for the gondola having a diameter substantially corresponding to the crossmember width.
  • the pivot bearing for the nacelle can be a slewing ring. This makes it possible to transmit the moments occurring when the nacelle is twisted relative to the crossbar and the gondola is loaded on one side without difficulty into the bearing and from there into the crossbar.
  • stops can be arranged on the gondola and the supporting structure.
  • a device for locking the nacelle relative to the supporting structure can be provided.
  • Fig. 1 the facade 1 of a building is shown, which has one or more facade parts 2 recessed relative to the facade 1.
  • a facade elevator In front of the facade 1 or in front of the facade part 2 there is a facade elevator with a gondola 4 which is suspended on ropes 5 and which can be moved vertically and horizontally in a plane parallel to the facade 1.
  • the gondola 4 shown has a box shape with side walls 6 reaching up to about waist height and a railing 7 fastened above the upper edge of the outer side wall 6 and reaching up to about chest height.
  • the nacelle 4 also has a floor 8 and has vertical stems 21-24 at its corners, which are connected at their upper ends to a roof structure 25.
  • the roof structure 25 forms with the stems 21-24 and the nacelle 4 a frame-like construction, which is connected via a bearing 9 designed as a slewing ring to a crossbar 15 suspended on the cables 5.
  • the slewing ring is designed so that it can also absorb the tensile forces resulting from the weight load. It can be seen that the nacelle 4 can be rotated about the axis 17 of the bearing 9 relative to the crossmember 9 until it assumes the position shown in broken lines.
  • the part of the bearing 9 belonging to the cross member 15 is mounted in a joint 26 with a horizontal axis 27 on the cross member 15.
  • the cross member 15 has a recess 28 in which the bearing part associated with the cross member 15 is movably arranged, and this bearing part is suspended on a pivot pin 29 which is held on both sides in brackets 30, 31. If necessary, stops 18, 19 can be provided which limit the pivoting movement about the horizontal axis 27.
