Definitions

  • the invention relates to an elevator installation with a shaft in which at least one car is vertically movable upwards and downwards and coupled to a counterweight via a cable or belt arrangement, the cable or belt arrangement having at least one cable or belt section, whose horizontal deflection can be limited by at least one limiting member.
  • Elevator systems with at least one car and at least one counterweight are known in various configurations.
  • the at least one car is still vertically up and down by means of a rope or belt arrangement in the shaft.
  • the cable or belt arrangement can be guided via a traction sheave, which forms a drive device for the car together with a drive motor which sets the traction sheave in rotation.
  • the car is coupled via the cable or belt assembly with a counterweight.
  • the cable or belt arrangement has a very long length. This can lead to the rope or belt arrangement being vibrated, for example, by a movement of the building in which the elevator installation is installed. Building movements of this kind can be caused by wind loads or, for example, by earthquakes. The vibrations lead to a deflection of the cable or belt assembly in the horizontal direction. In this case, there is the risk that a cable or belt section collides with a component of the elevator system, so that the cable or belt section or also the component of the elevator system is damaged.
  • WO 92/17396 proposes the use of a limiting member pivotable about a horizontal pivot axis, which can be positioned laterally on a cable or belt section in order to limit its horizontal deflection. If the limiting member is positioned laterally adjacent to a cable or belt portion while the car is traveling up or down, it may be the case that the cable or belt portion makes a movement relative to the limiting member and slides along the limiting member. This in turn may cause the rope or belt section to mechanically machine the limiting member. The limiting member must therefore have a high mechanical strength in order to avoid damage. In addition, the rope or belt section may also be damaged as it slides along the limiting member.
  • Object of the present invention is to develop an elevator system of the type mentioned in such a way that in the case of a horizontal deflection of a cable or belt section damage to a limiting member or the cable or belt section can be avoided.
  • At least one limiting member is designed as a limiting role, which is rotatably mounted laterally next to a rope or belt portion about an axis of rotation, wherein the limiting role of a controllable rotary drive in dependence on the speed and the direction of movement, which has the cable or belt portion arranged laterally next to the limiting roller relative to the axis of rotation of the limiting roller, can be set in rotation.
  • At least one limiting roller is used in the elevator installation according to the invention, which is rotatably mounted and can be rotated by a rotary drive.
  • a rotary drive This allows the speed of the side - - Has arranged next to the limiting role arranged rope or belt section with moving car relative to the limiting role to reduce.
  • the controllable rotary drive can set the limiting roller in rotation as a function of the speed and the direction of movement which the cable or belt section has relative to the axis of rotation of the limiting roller.
  • the rotary drive approximates the peripheral speed of the limiting roller, which in the case of vibration contacts the cable or belt section arranged laterally next to the limiting roller, approximating the relative speed of this cable or belt section, wherein the contact area of the limiting roller to which the cable is attached - or belt portion can be applied at a horizontal deflection, in the same direction moves up or down as the rope or belt section.
  • the cable or belt section and the contact area of the limiting roller thus have the same direction of movement. The greater the approach of the speeds, the smaller the speed at which the cable or belt section moves relative to the contact area of the restricting roller. This reduces the risk of damage to the rope or belt section and / or the limiting roller.
  • the controllable rotary drive can move the limiting roller clockwise and counterclockwise.
  • the direction of rotation and the circumferential speed of the limiting roller used to limit a vibration of a cable or belt section arranged laterally next to the limiting roller can be adapted to the speed and the direction of movement of this cable or belt section relative to the axis of rotation of the limiting roller , This has the consequence that the cable or belt section, if he performs a horizontal deflection during a ride of the car and contacted the adjacent limiting roller on the outer periphery, at best at low speed relative to - -
  • the peripheral speed of the limiting roller corresponds to the speed of the cable or belt section arranged laterally next to the limiting roller relative to the axis of rotation of the limiting roller.
  • the cable or belt section contacts the outer periphery of the limiting roller. If the limiting roller is rotated by its rotary drive in such a way that the circumferential speed of the limiting roller is identical to the speed which the cable or belt section has relative to the axis of rotation of the limiting roller, then the cable or belt section rolls upon contact with the outer circumference of the limiting roller without causing a sliding movement and a mechanical processing of the limiting roller. Damage to the limiting roller and / or the rope or belt section can thereby be reliably prevented.
  • the rotary drive which drives the limiting roller is coupled to an elevator control device, wherein the control device can provide the rotary drive with a control signal dependent on the speed and the direction of movement of the cable or belt section laterally adjacent to the limiting roller relative to the axis of rotation of the limiting roller is.
  • the elevator control device controls the travel of the car and, favorably, also determines the speed and the direction of movement which a cable or belt section arranged laterally next to a limiting roller has relative to the axis of rotation of the limiting roller.
  • the elevator control device can provide the rotary drive of the limiting roller a control signal under whose action the rotary drive drives the limiting roller to such a rotational movement that its direction of rotation and peripheral speed to the relative speed and the direction of the relative movement of the adjacent rope or Belt section are adjusted.
  • the peripheral speed and the direction of rotation of the restricting roller may change in accordance with the change in the relative speed and the change of direction of movement of the adjacent cable or belt section.
  • At least one limiting roller is rotatably mounted in a predetermined position in the shaft.
  • at least one limiting roller is arranged in the shaft center with respect to the vertical extent of the shaft.
  • the elevator system has a plurality of limiting rollers, which are arranged distributed uniformly in the shaft in an area between the uppermost stop of the at least one car and the lowermost stop of the at least one car.
  • At least one limiting roller is rotatably mounted on a car.
  • Such a positioning of at least one limiting roller on a car is particularly advantageous if a cable or belt section is guided along this car.
  • the at least one limiting roller can in this case limit a deflection in the direction of the car in the event of vibration of the cable or belt section, so that the cable or belt section can not impair the car even when vibrations occur.

Abstract

L'invention concerne une installation d'ascenseur comportant une cage dans laquelle au moins une cabine est apte à se déplacer vers le haut et vers le bas dans le sens vertical et est accouplée à un contrepoids par le biais d'un ensemble de câbles ou de courroies. L'ensemble de câbles ou de courroies comporte au moins une portion de câble ou de courroie dont la déviation horizontale peut être limitée par au moins un élément de limitation. Selon l'invention, pour perfectionner l'installation d'ascenseur de manière à pouvoir éviter d'endommager un élément de limitation en cas de déviation horizontale d'une portion de câble ou de courroie, au moins un élément de limitation est configuré en poulie de limitation qui est montée latéralement à côté d'une portion de câble ou de courroie de façon à pouvoir tourner sur un axe de rotation et qui peut être mise en rotation par un entraînement en rotation commandable en fonction de la vitesse et du sens de déplacement que la portion de câble ou de courroie, disposée latéralement à côté de la poulie de limitation, a par rapport à l'axe de rotation de la poulie de limitation.
