Definitions

  • the invention relates to an elevator installation with a safety device for relative position monitoring of components according to the preamble of claim 1 and to a method for relative position monitoring of components in an elevator installation according to the preamble of claim 16.
  • the invention is intended to ensure monitoring of the operation of a deflection roller of a suspension element of the elevator installation.
  • the solution of the problem is defined by the features of claim 1.
  • This relates to an elevator installation with a safety device for the relative position monitoring of components in the elevator installation.
  • the elevator installation comprises a component to which a relatively fixed component is fastened in a predetermined desired position.
  • the safety device is designed and arranged such that a positional deviation of the fixed component from the desired position with respect to the component can be monitored, wherein when a predeterminable position deviation is exceeded by the safety device, an alarm signal can be generated.
  • the elevator installation is characterized in that the safety device is designed and arranged such that the positional deviation that can be monitored by the safety device comprises a rotation and / or a translation of the stationary component with respect to the component to which it is fastened.
  • a relatively fixed component is presently referred to a component which is rigidly mounted in the operative state with respect to the component to which it is attached.
  • a mobility relative to the component is provided neither during operation nor out of service.
  • the fixed component e.g. can be releasably secured for maintenance purposes.
  • Such components may for example be bolted to the component, riveted, welded or have an interference fit.
  • the component to which the component is fixed relatively fixed can be arranged movably in the elevator system.
  • Alarm signal here refers generally to a signal generated by the safety device, which can be utilized in different ways by other units of the elevator system.
  • the alarm signal can be forwarded to a control of the elevator installation, which blocks operation of the elevator system as a result of the alarm signal, for example in an emergency shutdown or an emergency stop.
  • the safety device may include an alarm device, which further processes the alarm signal. In principle, it is also conceivable, for example, to only register the alarm signal and, for example, store it in a memory.
  • a desired position of the relatively stationary component denotes a position in which it is attached to the component in the wide operating state within the scope of a manufacturing or installation tolerance.
  • positional deviations from this desired position may generally occur in the course of operation, which pose no safety risk and therefore do not have to result in an alarm signal.
  • Due to the predeterminable positional deviation at which the alarm signal is generated a range of tolerable positions around the desired position is thus definable. Only when the predeterminable positional deviation is reached, the alarm signal is generated according to the invention. It is understood that, for safety reasons, the tolerable range which can be predetermined by the predefinable positional deviations is generally narrow for safety reasons.
  • a corresponding safety device can be made particularly simple, since in the construction no relative movement has to be considered. Elements of the safety device can therefore be only mechanically negligible or not stressed during normal operation. This is also associated with little or negligible mechanical wear. Likewise, a comparatively low precision in the monitoring of a relatively fixed component is usually required. If such a component has once been released, this usually results in a comparatively significant change in position.
  • the monitoring provided by the safety device of the elevator installation according to the invention is thus fundamentally to be distinguished from known position monitors, in which components moving relative to one another, e.g. for the determination of a position of the car or its speed can be precisely monitored.
  • a rotation ie a rotation of the relatively fixed component with respect to the component to which it is attached
  • a translation ie a displacement of the component relative to the component and a combination of both position
  • the safety device is versatile in the elevator system used.
  • the safety device is also suitable for relatively fixed bearing parts of rotary bearings such as axle or bearing sleeves. On such bearing parts can act large torques in case of failure of the bearing, which can solve the attachment of the relatively fixed bearing part.
  • An additional monitoring of a translation ie a displacement of the component relative to the component, ensures additional security even with pivot bearings.
  • monitoring both rotation and translation, or a combination of both may be beneficial to any type of relatively stationary component. Depending on the type of component, eg with only statically loaded components, it may be sufficient to monitor only one translation.
  • the safety device of the elevator installation according to the invention is particularly suitable for monitoring fixed bearing parts of rotatingly mounted elements.
  • the fixed component is a bearing part of a pivot bearing, in particular an axle body, a deflection roller which is rotatably mounted on the bearing with respect to the component at this. It is understood that depending on the design of the pivot bearing, other relatively fixed parts of rolling bearings or plain bearings can be monitored such. Bearing sleeves.
  • the fixed component is a bearing part of a deflection roller for a support means for supporting an elevator car.
  • the support means is connected via the pulley to the elevator car and wraps around the pulley at least partially.
  • a support means for example, carrying ropes, straps or straps can be used.
  • Such pulleys are used, for example in 2: 1 installations for the application in which the support means is fixed with both ends to the ceiling (pit head) of the elevator shaft, while cabin and counterweight depending hang by means of pulleys on the support means.

  • the positional deviation from the desired position which can be monitored by the safety device preferably comprises a deviation component in the direction perpendicular to the direction of movement of the movable component.
  • This deviation component may in particular result from a rotation with respect to a geometric axis, which is arranged perpendicular to the direction of movement or else a translation.
  • the safety device comprises a detection element for detecting the positional deviation of the fixed component from the desired position and a triggering element, which can cooperate with the safety device for triggering the alarm signal.
  • Detection element and triggering element are arranged and designed such that they can cooperate at least when reaching the predetermined positional deviation of the fixed component of the desired position for triggering the alarm signal.
  • the elements can be arranged on different components of the elevator installation.
  • the detection element may for example be attached to the stationary component of a movable component, while the trigger element is arranged stationarily in the elevator installation.
  • the detection element and trigger element are arranged without contact to each other when a positional deviation of the fixed component is less than the predetermined position deviation. This is particularly advantageous in the case of movable components, since, given a suitable design and relative arrangement of the detection element and the triggering element, movement of the component is not hindered.

  • a tensile force in the trigger element can be generated during the interaction.
  • the triggering element may, in the manner of a ripcord, be able to be ripped from a fastening or separated at a predetermined breaking point due to the force effect for actuating a switching device.

  • a trip element designed as a wire is also used when the alarm signal is triggered mechanically.
  • no electrical conductivity is required, which is why, in principle, e.g. Also, a plastic wire or plastic rope can be used.
  • the formation of the trigger element as a wire in this case has the advantage that a mechanical interaction of detection element and trigger element also allows deformation of the trigger element.
  • the wire can be wound up by the detection element due to the positional deviation of the relatively stationary component, whereby a tensile force in the wire can be generated to trigger the alarm signal.
  • the wire may e.g. also be severed directly from the detection element.
