Definitions

  • the invention relates to a drive frame in an elevator installation.
  • Such drive frames are used to store a drive roller in the elevator system can.
  • Elevator installations usually comprise an elevator car, a counterweight, a drive unit, a drive roller and a support element.
  • the support element couples the elevator car and the counterweight.
  • the support element may be guided in an upper region of the elevator installation via the drive roller. It is customary to let segments of the support element, which lead from the drive roller to a suspension on the elevator car on the one hand and to a suspension on the counterweight on the other hand, run almost parallel.
  • a distance roller A distance of these two parallel segments of the support element is referred to as support element spacing.
  • drive units can be replaced with respective associated drive roller and optional spacer roll by drive frame on which these functional units are stored.
  • the drive frames can be designed so that the support element spacing can be varied. This makes it possible to use drive frame of the same type in elevator systems, which differ from each other by different support element distances. It is important that in any case a sufficiently high wrap of the drive roller is present through the support member to ensure sufficient traction between the drive roller and the support member.
  • WO 2006010785 shows a drive frame with a drive unit consisting of a prime mover, a drive and deflection roller, and a spacer roller unit.
  • a drive unit consisting of a prime mover, a drive and deflection roller, and a spacer roller unit.
  • a support element spacing is variable.
  • the deflection roller is arranged under the drive roller to ensure a constant wrap of the drive roller regardless of the preset carrier element spacing.
  • EP 0 763 495 A1 discloses an elevator installation according to the preamble of claim 1.
  • the object of the invention is therefore to provide a drive frame with adjustable roller spacing, the maintenance cost is lower.
  • the object is achieved by an elevator installation with a drive frame and a drive unit, wherein a support element couples an elevator car with a counterweight, whereby a drive roller and a spacer roller are mounted on an associated holding device on the drive frame, the support element being guided over the spacer roller and the drive roller wherein at least one of the holding devices is fixable to at least two positions on the drive frame, thereby varying a horizontal support element spacing, wherein an entire course of the support element between the drive roller and the spacer roller is substantially rectilinear.
  • the invention is based on the finding that independent of the carrier element spacing, a constant and sufficiently high looping of the drive roller through the carrier element leads to the best possible mode of operation. It is advantageous that moving parts are reduced to a minimum. Thus, the maintenance and installation costs can be reduced. Assemblies that can be fixed on the drive frame at different locations for varying the distance between the carrier elements are reduced to a minimum in size. A possible avoidance of a counterbending of the support element in this way also increases the service life of the support element.
  • the at least two positions for fixing the at least one holding device along a straight line are arranged substantially parallel to the rectilinear course of the supporting element. This makes it possible regardless of the chosen location of the fixation to make a course of the support element identical.
  • the support element thus forms independent of the support element spacing at deflection points in the region of the drive frame always the same angle. This allows a drive frame to be optimally adapted to all conditions.
  • the holding device for the distance roller can be fixed to at least two positions on the drive frame.
  • the at least one holding device is fixed to the drive frame by screw connections or frictionally engaged connections.
  • the holding devices on the drive frame can be quickly released or fixed by a fitter or service specialist.
  • a support element spacing can be adjusted on site in the elevator system.
  • both segments of the support element which are arranged directly on the drive roller and run essentially in a straight line, form an acute angle.
  • a high wrap or a blunt wrap of the support member can be achieved to the drive roller.
  • this acute angle has a size within a range of 10 ° to 80 °.
  • At least one end of the support element is fixed by means of a fixed point device to the drive frame, wherein the fixed-point device is arranged on one of the holding devices.
  • a measuring device for determining a measured variable is arranged on the fixed point device.
  • a drive unit is attached to the drive frame.
  • FIG. 1 shows an elevator installation 2 in an elevator shaft 4.
  • the elevator shaft 4 is bounded by shaft walls 6.
  • the elevator installation 2 comprises an elevator cage 10 and a counterweight 8.
  • the elevator cage 10 and the counterweight 8 are suspended on a support element 12.
  • the support element 12 is guided in an upper region of the elevator shaft 4 via a drive roller 20 and a spacer roller 22.
  • the drive roller 20 is coupled to a drive unit 18 and operatively connected thereto.
  • the drive roller 20 and the spacer roller 22 are mounted on a drive frame 16.
  • the drive frame 16 may be fixed on a load surface 14.
  • the support element spacing 34 can be dimensioned differently in different elevator systems.
  • FIG. 2 and FIG. 3 show a drive frame 16 according to the invention with arranged thereon Elements.
  • the drive frame 16 is arranged in an upper area of the elevator installation 2 and constitutes a load-bearing structure.
  • a projection of the drive frame 16, according to FIGS FIG. 3 shown side view, has a shape similar to a right triangle.
  • On the drive frame 16 are holding devices 30, 32 fixed, which are arranged near the acute-angled vertices of this projected right triangle. These holding devices are a drive roller storage unit 30 and a spacer roller storage unit 32.
  • a drive roller 20 is supported on the drive roller storage unit 30.
  • On the drive roller storage unit 30, a drive unit 18 may be attached. The drive unit 18 is operatively connected to the drive roller 20.
  • a spacer roller 22 is mounted at the pitch roller bearing unit 32.
  • the counterweight and the elevator car are not shown.
  • the support member 12 extends upwardly from the elevator car, is deflected by the drive roller 20 and the spacer roller 22 down to the counterweight.
  • the course of a first segment 12.1 of the support element 12 from the drive roller 20 to the spacer roller 22 is substantially rectilinear and inclined.
  • a fixed point device 28.2 may be arranged on the drive roller side on the drive frame 16.
  • the drive roller support unit 30 can be fastened to the drive frame 16 by means of screw connections 44.
  • a use of frictional connections is another way to fix one of the holding devices 30, 32 on the drive frame 16, whose position on the drive frame 16 is variable.
  • FIG. 2 shows the drive frame 16 in a perspective view.
  • the drive frame 16 may also have pitch roller fixing holes 42 for securing the pitch roller bearing unit 32 to the drive frame 16.
  • the spacer roller bearing unit 32 can thus be fastened to the drive frame 16 with screw connections 44.
  • the Abstandsrollenlagerungstechnik 32 may be secured by other known fasteners or fastening methods on the drive frame 16.
  • the support member 12 may be partially covered by covers 24.
  • FIG. 3 shows the drive frame 16 in a side view. From the elevator car to the drive roller 20, a cabin-side segment 12.2 of the support element 12 extends substantially vertically. From the counterweight to the spacer roller 22 is a gegenconsistss workedes Segment 12.3 of the support member 12 also substantially perpendicular. A support element spacing 34 corresponds to a distance between the cabin-side segment 12.2 of the support element 12 and the counterweight-side segment 12.3 of the support element 12. The essentially straight course of the first segment 12.1 of the support element 12 forms an acute angle 50 to the cabin-side segment 12.2 of the support element 12. Both segments 12.1, 12.2 are arranged directly on the drive roller 20.
  • the acute angle 50 of the support element 12 on the drive roller 12 leads to a looping of the support member 12 on the drive roller 20.
  • the wrap is characterized by the wrap angle 26 which is blunt corresponding to the acute angle 50.
  • the wrapping angle 26 corresponds to an angle 180 ° minus the acute angle 50.
  • the angle 180 ° corresponds to half the full angle.
  • the acute angle 50 is preferably in a range between about 10 ° and about 80 °. The result is a sufficiently high angle of wrap 26 and a limitation of a height of the drive frame 16 to a reasonable degree.
  • the drive frame 16 may have drive roller fixing holes 40. These drive roller fixing holes 40 are provided to fix the drive roller support unit 30 to the drive frame 16 by means of the screw connections 44.
  • the drive roller fixing holes 40 are made multiple, so that the drive roller support unit 30 can be fixed at different positions on the drive frame 16. The positions extend along a straight line, which are arranged substantially parallel to the rectilinear course of the support element 12, that is, the first segment 12.1 thereof.
  • the drive roller support unit 30 may alternatively be secured to the drive frame 16 by other fasteners or attachment methods.
  • the drive roller supporting unit 30 can be mounted on the drive frame 16 at the various positions without changing the wrap angle 26 thereby.
  • a selective attachment of the drive roller bearing unit 30 results in a variability of the support member spacing 34.
  • a constant angle of wrap 26 of the support member 12 on the drive roller 20 with simultaneous variability of the support element spacing 34 in different elevator systems guarantees a well-defined operation.
  • the fixed point devices 28.1, 28.2 are intended to fix one of the ends of the support element 12 in the elevator installation 2.
  • the fixed point devices 28.1, 28.2 are arranged on the holding devices 30, 32. If the support element spacing 34 is changed according to the drive frame 16 according to the invention, this essentially vertical course is unaffected.
