Definitions

  • the present invention relates to an elevator arrangement as defined in the preamble of claim 1.
  • a common solution in elevators without machine room is to mount the elevator machine on guide rails attached to the walls of the elevator shaft. Via the guide rails, the load imposed by the weight is transmitted to the bottom of the shaft. Thus, the weight of almost all of the elevator structures rests on guide rails attached to the wall. As both the machine, the car, the counterweight, all diverting pulleys and the ends of the elevator ropes are supported directly or indirectly on the guide rails, this places strict requirements on the guide rails and the manner in which they are fixed to the wall .
  • the guide rails need to be of a robust design, which in itself may increase the manufacturing costs.
  • the guide rails must be attached to the wall of the elevator shaft with fixtures placed at relatively short distances from each other, which is often difficult because there are only a limited number of points where the guide rails can reasonably be attached. In many cases, it is only at the floors that the guide rails can be sufficiently firmly fixed to the building. Increasing the number of points of guide rail attachment means an extra increase in both material costs and installation expenses.
  • EP 849209 also presents a prior-art application which uses a separate pole of a height ex- tending through the whole shaft, the machine being mounted on the upper end of the pole so that the entire weight of the machine is transmitted via the pole to the bottom of the shaft.
  • this application requires complex pole structures and supports and it is therefore not a realistic alternative to other known structures .
  • the object of the invention is to eliminate the above- mentioned drawbacks.
  • a specific object of the invention is to disclose a new type of elevator arrangement which, being relatively independent of the elevator shaft, allows correct application of the effect of the forces acting in the elevator shaft as well as optimal design of the structures used in respect of both size, weight and costs.
  • a further object of the invention is to achieve simpler and faster installation of the various components of the elevator in the elevator shaft.
  • the elevator arrangement of the invention comprises an elevator shaft with at least one guide rail extending vertically in the elevator shaft, said guide rail serving to guide an elevator car moving in the shaft.
  • the elevator arrangement comprises a counterweight with possible guide rails as well as an elevator machine with elevator ropes and diverting pulleys for moving the elevator car and counterweight in the elevator shaft.
  • the elevator machine is mounted on the guide rail and the machine preferably consists of a discoid flat permanent magnet synchronous motor which can be mounted in the space be- tween the elevator car and the wall of the elevator shaft.
  • the elevator arrangement comprises an auxiliary support between the elevator shaft and the elevator machine, preferably a mainly vertical structure extending in the longitudinal direction of the shaft and bearing part of the weight of the elevator machine.
  • the auxiliary support may be an element separate from the guide rail or it may be a sup- porting element attached to the guide rail, designed to receive a vertical load.
  • auxiliary support preferably rests in the lower part of the elevator shaft, e.g. on the bottom of the elevator shaft, but other points of support are also possible.
  • the auxiliary support may also pass the load of the machine to other points along the vertical dimension of the shaft.
  • the elevator shaft may be provided with several auxiliary supports according to the invention, with e.g. one support on either side of the elevator car and one on either side of the counterweight.
  • the number of auxil-sammlungy supports may vary from case to case, in such manner that a sufficient proportion of the vertical loads otherwise applied to the guide rails can be passed via the auxiliary supports past the guide rails to the structures of the elevator shaft, preferably to its bottom.
  • all vertical forces applied to the auxiliary supports by the auxiliary supports themselves and the loads supported by them are applied to the bottom of the elevator shaft.
  • the auxiliary supports are braced using lateral supports attached to the walls of the elevator shaft at vertical distances from each other, said lateral supports only keeping the auxiliary support upright without support- ing it vertically in any way.
  • Such lateral supports may consist of e.g. sleeve-like or collar-like fixtures placed around the auxiliary support to hold it, yet without preventing movement of the auxiliary support through the collar or sleeve.
  • Such collars or sleeves can then be attached to the wall of the elevator shaft so that only insignificant horizontal supporting forces are applied to the wall .
  • auxiliary supports can be used to support various structures and parts of the elevator.
  • one end or both ends of the elevator rope can be attached directly or indirectly to an auxiliary support.
  • one or more of the car or counterweight guide rails may be completely or partially supported by an auxiliary support.
  • the elevator machine mounted on a guide rail or the ends of the ropes can be attached to this bracing structure, through which a significant proportion of the loads is passed to the auxiliary supports and further e.g. to the bottom of the elevator shaft.
  • the elevator arrangement of the invention comprises only one auxiliary support.
  • the largest and most significant vertical loads of the elevator structure can be passed to the auxil- iary support.
  • the guide rail itself can be at least partially supported by the auxiliary support.
  • both ends of the elevator rope can be connected to the same auxiliary support to reduce the loads applied to the guide rails and certain parts of the elevator shaft and to apply the loads to more appropriate points .
  • the auxiliary supports used may consist of various steel and/or concrete structures.
  • a preferred structural solution for the auxiliary support is a straight steel tube filled with concrete.
  • other auxiliary support structures that are sufficiently rigid and have a sufficient load-bearing capacity may be used as well .
  • the elevator arrangement of the invention has significant advantages:
  • an elevator can be installed in a space which does not provide sufficient possibilities for mounting the elevator components in the traditional manner, - since constructing an elevator is made less dependent on the environment in which it will be used, i.e. the elevator shaft, the elevator manufacturer will be able to produce in a controlled factory environment easy-fit elevator packages, larger assemblies to be installed at once, thus allowing faster installation of the elevator in the elevator shaft and reducing the error potential.
  • the elevator arrangement presented in the drawing comprises an elevator shaft 1 with a bottom 10 and walls. Placed in the elevator shaft are two guide rails 2 de- signed to guide an elevator car 3 moving along them. Mounted on one of the guide rails 2 is an elevator machine 5, which consists of a permanent magnet synchronous motor. In addition, the shaft is provided with another pair of guide rails 11, designed to guide a coun- terweight 4 moving along them. Although the elevator machine 5 is attached to the guide rail 2, its weight is not applied exclusively to the guide rail but the machine is supported by a separate auxiliary support 9 on the bottom 10 of the elevator shaft.
  • the auxiliary support 9 consists of a vertical pole extending directly down from the elevator machine to the bottom of the elevator shaft. Therefore, the guide rail or its fixtures need not be designed to withstand all the loads produced by the elevator car 3 , the counterweight 4 or the elevator machine 5, because part of the stress caused by these loads is transmitted via the auxiliary support 9 directly to the bottom 10 of the elevator shaft .
  • the auxiliary support 9 is preferably fastened to the wall of the elevator shaft via sleeve-like or collarlike lateral supports so that only slight horizontal supporting forces are applied to the wall of the elevator shaft.
  • one end of the elevator rope 6 is fixed to the upper end of one 2 of the guide rails for the car 3. From there, the elevator rope runs to diverting pulleys 7 at the bottom of the elevator car and upward again to the traction sheave of the elevator machine 5 mounted on the other guide rail 2. From here, the elevator rope runs downward via a diverting pulley 8 on the counterweight 4 and further up toward the upper end of one of the guide rails 11 for the counterweight 4, where the rope end is fixed.
  • a significant proportion of the loads acting in the elevator arrangement, imposed by the car 3 , the counterweight 4 and the elevator machine 5, is applied via the auxiliary support 9 to the bottom 10 of the elevator shaft. The stress caused by these loads is therefore not applied to the guide rails and via these to the walls of the elevator shaft.
  • the elevator arrangement presented in the diagram may also be provided with several auxiliary supports, which can be used to support the points of anchorage of the rope 6 on the guide rails 2 and 11.
  • the auxiliary support 9 supporting the elevator machine may be provided with additional structures to transmit the stresses applied to the guide rails by the rope 6 to the auxiliary support and via it to the bottom 10 of the shaft.
