Definitions

  • the invention relates to an elevator installation with a linear drive system according to the preamble of claim 1 and a linear drive system for an elevator installation according to the preamble of claim 14.
  • FIGS. 1A, 1B and 2A, 2B various basic configurations of elevator systems with permanent magnet linear drive systems.
  • FIG. 1A and 1B a configuration is shown in which an elevator car 13 by means of a permanent magnet linear drive system 10, 11 is moved along a lift shaft in the y direction.
  • a permanent magnet linear drive system comprises a stationary part 10 fixed in the shaft and a movable part 11 fixed to the elevator car 13. From the top view in Fig. 1B It can be seen that in such a configuration no guidance takes place in the yz plane, so that additional guide shoes are to be provided on the elevator car 13, which guide the elevator car 13 along guide rails 12 arranged to the right and left of the elevator car 13.
  • a comparable elevator installation is the patent application EP 0 785 162 A1 refer to.
  • the permanent magnet linear drive system comprises a stationary part 10 and two movable parts 12. This achieves guidance in the yz plane.
  • guide rails are also required, or the elevator car 13 would be supported by further support means, such as a cable 12 'mounted centrally on the elevator car.
  • an elevator has become known with an elevator car which can be moved in an elevator shaft and two counterweights which are connected to the elevator car by means of carrying cables guided by deflection rollers.
  • the elevator car and the counterweights are driven by means of linear motors arranged at the rear shaft corners and cabin corners.
  • the known solutions are not or only partially suitable for elevator system in backpack configuration, which require only one wall of the elevator shaft for drive, suspension and guidance for structural or aesthetic reasons.
  • FIG. 3 Now the backpack principle is transmitted to an elevator system with permanent magnet linear drive system, which is a highly schematic representation.
  • the elevator car 14 sits on an L-shaped cabin frame on the upright leg of the movable part 11 of the permanent magnet linear drive system is fixed. Perpendicular in the elevator shaft, the stationary part 10 of the drive is attached (analogous to the in Fig. 1A shown arrangement). There are strong attractive forces between the moving part 11 and the stationary part 10, which are directed in the normal direction and designated F N.
  • the elevator car 14 can be moved up or down, as represented by the force vectors F on and F ab .
  • a backpack configuration of the type shown now comes - caused by the weight F K of the loaded or unloaded elevator car 14 - a torque D added to the permanent magnet linear drive system acts as indicated by a double arrow.
  • FIG. 4A is a schematic perspective view of a portion of a shaft rear wall 26 with the parts 20, 21 of the direct drive permanent magnet linear drive system shown.
  • the stationary part 20 (also called support column) of the drive system is attached to the shaft rear wall 26 and has a longitudinal axis L y , which extends parallel to the y-direction.
  • at least two inclined interaction surfaces a1, a2 arranged on the stationary part 20 are provided.
  • the drive system has at least two movable parts 21 (also called units), wherein each one of the movable parts 21 is associated with one of the interaction surfaces a1, a2.
  • Each interaction surface a1, a2 is associated with an interaction length b oriented in the y direction.
  • the interaction length b is the length between a terminal guide point and the center of a movable 21. While repulsive forces occur at the terminal guide point, take place in the center of the movable member 21 attractive forces.
  • the interaction length b is thus the effective length which prevents a tilting movement of the elevator car 24 in the xy plane.
  • the interaction length b extends over a portion of the elevator car 24, it is less than or equal to the height of the elevator car 24. If the drive system is controlled in a suitable manner, the elevator car 24 can be moved up or down, as by the force vectors F on and F ab are shown.
  • the ratio of attraction F N divided by force vectors F on and F ab is referred to as force ratio K.
  • the force ratio K is typically in the range of 2 to 20, preferably in the range of 3 to 10.
  • Fig. 4B It can be seen by way of indication that the elevator car 24 is arranged in a backpack configuration.
  • the axes of rotation D x , D y and D z engaging in the cabin center of gravity are in Fig. 4B shown.
  • F N The distance between the car's center of gravity and the interaction surfaces a1, a2 is referred to as the line of action L x .
  • the center connecting end of the interaction surfaces a1, a2 extending in the z direction is used as a reference.
  • the line of action L x is therefore the shortest distance between the car's center of gravity and this center connecting.
  • the parts 20, 21 by a small air gap from each other spaced.
  • the air gap is for example 1mm wide.
  • the air gap has the advantage that it allows non-contact guiding of each of the movable parts 21 on the corresponding stationary part 20. The vertical movement of the elevator car 24 is thus guided via the permanent magnet linear drive system via the moving parts 21 without contact on the stationary part.
  • the term permanent magnet linear drive system is used to describe a direct drive system that includes a permanent magnet excited synchronous linear motor.
  • the corresponding surfaces of the stationary part of the permanent magnet linear drive system are referred to as interaction surfaces, since there is an interaction between these surfaces and the movable units of the drive system.
  • a linear drive system with at least one permanent magnet it is also possible to use a linear drive system with at least one layer structure with at least one coil.
  • the movable part may be designed as a layered structure made by applying various layers to a substrate.
  • the layers can be applied one after the other and optionally structured appropriately. In this way, three-dimensional structures of materials with different properties can be applied to the substrate.
  • Individual layers may consist of an electrically insulating material or comprise regions of an electrically insulating material.
  • the conductor track can be composed of conductor track sections which are each formed in different layers of the layer structure. Individual sections of the conductor track may, for example, cross over in different planes and be separated by an electrically insulating layer in the region of the crossing. Furthermore, it is possible to arrange individual sections of the conductor track in different layers separated by an intermediate layer and to provide an electrically conductive region in the intermediate layer, which establishes an electrical connection between these sections of the conductor track.
  • Layers of the type mentioned can also be applied on both sides of the substrate and optionally structured. For example, it is provided that a first part of the conductor track on a first surface of the substrate and a second part of the conductor track on a second surface of the substrate Substrate is formed, wherein an electrical connection between the first and the second part is made. This makes it possible to give the track a particularly complex geometric structure.
  • At least a portion of the conductor track may have the form of a coil, wherein each coil comprises one or more windings.
  • the coil may be disposed on one side of the substrate, but it may also be composed of various portions of the trace disposed on different sides of the substrate and electrically connected together.
  • a plurality of serially arranged sections of the conductor track can each have the shape of a coil, the coils being designed such that adjacent coils generate magnetic fields with different polarity in the case of a current flow through the conductor track.
  • the track may be arranged such that upon supplying the track with a DC current to a surface of the movable member, a static magnetic field is generated whose polarity is a periodic reversal of polarity along the direction in which the movable member is movable relative to the static member is, has. In this way, a movable part can be formed to provide a large number of magnetic poles.
  • the area available on the substrate can be used efficiently. This is relevant for optimizing the efficiency of the linear drive system and the accuracy with which the Movement of the movable part relative to the static part during operation of the linear drive system can be controlled.
  • the two inclined interaction surfaces a1, a2 extend parallel to the longitudinal axis L y and lie in planes which enclose an angle W greater than 0 ° and less than 180 ° (ie 0 ° ⁇ W ⁇ 180 °).
  • the surface normals of the interaction surfaces a1, a2 are directed toward the elevator car 24.
  • the angle W is between 20 ° and 160 °.
  • the angle W for an eccentricity of 0.7 and a force ratio K of 4 is about 120 °.
  • the movable part comprises at least two units 21, which are arranged together on a rear side 27 of the elevator car 24 and positively connected to the elevator car 24 that when driving each of the two units 21 an upward or downward movement along one of the interaction surfaces a1, a2 causes. Thereby, the elevator car 24 can be moved up or down. Due to the oblique arrangement of the two interaction surfaces a1 and a2, the attractive forces F N of the drive system at least partially compensate each other. This helps to avoid the disadvantage of the very high attractive forces and associated friction losses of previous drive systems with permanent magnet linear drive.
  • FIG. 4B Next is in Fig. 4B to recognize that the elevator car 24 on the rear side 27 a cabin frame 25, or an equal acting means, on the one hand, the two units 21 are positively mounted, and on the other hand designed for eccentric carrying the elevator car 24.
  • the elevator installation is located in an elevator shaft, whereby according to the invention only one type of shaft rear wall 26 is required to accommodate the mechanical / technical elements of the elevator installation.
  • FIGs. 5A and 5B two plan views of parts of two other embodiments of elevator systems 1 according to the invention are shown.
  • a rear shaft wall 26 is shown.
  • the stationary part 20 of the drive system is arranged.
  • the stationary part 20 has at least two inclined interaction surfaces a1 and a2. While the interaction surfaces a1 and a2 in the embodiment according to Fig. 5A are inclined away from each other, they are in the embodiment according to Fig. 5B inclined towards each other.
  • the angle W is about 120 °.
  • the attractive forces F N of the drive system can be broken down into the force components F Q (transverse forces) and F H (holding forces).
  • the two transverse forces of the two units 21 compensate each other, since they are both directed parallel to the z-direction, but pointing in opposite directions. Effectively we carried the elevator car 24 by the holding forces F H. By this partial compensation of the forces, the otherwise existing friction between the stationary part 20 and the moving parts 21 is significantly reduced.
  • the stationary part 20 is according to the invention in cross-section perpendicular to the longitudinal axis L y preferably polygonal and the surface normals of the two interaction surfaces a1, a2 tend away from each other or tend towards each other. Both times they point to the elevator car 24.
  • the attractive forces of the permanent magnets of the permanent magnet linear drive system serve for stabilizing the eccentrically arranged elevator car 24 and for spatial stabilization and guidance.
  • the reaction forces are reduced to support the leadership of the drive system and thereby reduces the frictional forces.
  • the compensation of the transverse forces F Q , as well as the stabilization in the axis of rotation D z can be defined in the design of an elevator installation or a corresponding permanent magnet linear drive system.
  • the stationary part 20 of the permanent magnet linear drive system is thus used for the spatial guidance of the backpack elevator car 24.
  • the stationary part 20 has a niche or tray a3 in an upper area. As in Fig. 4A 7A and 7B, the tray a3 is located on the upper end of the stationary part 20. It is at least partially enclosed by the interaction surfaces a1, a2 and can be used for mounting manhole components. Thus, shaft components such as a position sensor, a brake partner of a holding brake or even a form-fitting retaining bolt can be attached here.
  • Embodiments in which the movable parts 21 of the drive system are fastened in the upper region of the rear of the cabin 27 are particularly advantageous.
  • the embodiments can be realized with or without further support means for supporting the elevator car 24.

Accordingly, the interaction length b extends from the terminal guide point of a first movable part 21 to the center of the second movable part 21 of the same interaction area a1, a2.
  • Fig. 7B shows an elevator system 1 with a main guide in moving parts 21 and an auxiliary guide in at least one guide shoe 22. While each of the movable parts 21 is guided on one of the two obliquely inclined interaction surfaces a, b, the guide shoe 22 laterally adjacent to the stationary part 20th guided on a guide rail. According to Fig.
