Definitions

  • the present invention relates to an elevator installation with reduced shaft pit depth.
  • the invention relates to the protection of the pit or the establishment of a temporary shelter in the pit.
  • the GB 518,044 discloses a lift cage with an emergency stop button that can be triggered or actuated on the passenger side. An actuation of this emergency stop button has an interruption of the electrical circuits and thus stopping the drive of the elevator cage result, so that the elevator cage comes to a halt immediately after an actuation of the emergency stop button.
  • the known safety gears are usually triggered by a speed limiter or a so-called slack rope detection.
  • the triggering can be done both mechanically and electrically, but also in other ways such as pneumatic or hydraulic.
  • the safety gear is actuated / triggered when a person wants to enter the shaft pit. This can on the one hand consciously by the person himself by pressing a correspondingly provided button, pulling a ni Levers or the like happened.
  • This particular electrical or mechanical device for triggering the safety gear (triggering device) is preferably arranged outside of the hoistway, and is operated by the person before entering the hoistway.
  • the access door of the elevator shaft for example by a so-called emergency release only openable, if previously the triggering device has been pressed.
  • the safety gear can be activated when the car is in a predetermined or predeterminable distance to the pit floor or the car falls below this minimum distance.
  • the triggering device is in operative connection with one of the lower access doors (and possibly other doors) to the elevator shaft, so that when the door is opened manually, the safety gear is automatically released.
  • the safety gear is triggered even when entering the shaft by a person who has no knowledge of a tripping device arranged outside the shaft.
  • the activation takes place when opening the door only when the car is in a predetermined or predeterminable height above the shaft floor. This height is given, for example, when a person can slip through between the front lower edge of the car and the shaft bottom of the door.
  • means for activating in the pit may be provided directly, which are automatically actuated upon entering the pit and trigger the safety gear.
  • tripping devices may be, for example, light barriers (with light in the visible or invisible region), sensor mats (contact or anti-tread mats), gratings or step plates, Tension wires, or other known triggering options that produce a signal to trigger the safety gear or trigger the safety gear directly when entering / interrupting or otherwise actuated.
  • Other triggering options include the use of ultrasound or radar, inductive and / or capacitive means or piezo-based means.
  • the mats / grates can be supported over the entire surface or only in areas and can have switches with displacement or pressure evaluation.
  • sensors are provided in the car bay, which cause a triggering of the safety gear when the car falls below a minimum height above the pit floor.
  • the sensors are activated only after opening the access door.
  • the tripping device advantageously comprises a circuit arrangement with two stable states, which is set from its first stable state to the second stable state upon actuation of the tripping device.
  • the safety gear is disabled again.
  • the switching device with the two stable states remains after closing the access door, leaving the treadmats, etc. in the second stable position, and can only be operated again from outside the shaft and returned to the starting position.
  • the safety gear is triggered, so that no driving movement of the car or no driving movement of the car in the bottom stop is possible.
  • the safety gear is triggered directly independently of upstream speed sensors or speed monitoring.
  • the invention is of course not limited to the use of safety devices on guide rails.
  • catch or brake devices on suspension or brake cables or a piston brake for hydraulic cylinders (hydraulic lifts) can be used.
  • a safety gear may also be used to hold or jam the shaft walls or brake rails. If the hoistway is designed as a shaft scaffold, then the safety gear can also act directly on parts of the scaffold.
  • a Fahrwegbe dictionary can be introduced into the train of the car after the blockage of the car by the safety gear in addition.
  • the introduction of the Fahrwegbeskyrs can be done manually or automatically.
  • the invention also encompasses a method for operating an elevator installation, in which a temporary shelter is set up under a car of the elevator installation in which a safety gear (already present in a cable lift) is activated.

Claims (10)

  1. Installation d'ascenseur comprenant une cabine ascenseur mobile dans une cage d'ascenseur avec une fosse de profondeur réduite, et un dispositif parachute agissant sur le mouvement de déplacement de la cabine d'ascenseur et déclenchable par des premiers moyens d'activation, caractérisée en ce qu'il est prévu des seconds moyens additionnels pour activer le dispositif parachute, étant défini par activation à l'aide des seconds moyens additionnels pour activer le dispositif parachute un espace de protection temporaire sous la cabine d'ascenseur.
  2. Installation d'ascenseur selon la revendication 1, dans laquelle le dispositif parachute est réalisé pour venir engager des rails, des câbles, des vérins hydrauliques, des parois de cage, ou d'autres surfaces de freinage appropriées.
  3. Installation d'ascenseur selon la revendication 1 ou 2, dans laquelle une activation du dispositif parachute a lieu lorsque le fond de la cabine d'ascenseur se trouve à une distance prédéterminée au-dessus du fond de la fosse de cage.
  4. Installation d'ascenseur selon la revendication 1 ou 2, dans laquelle une activation du dispositif parachute a lieu lorsque le fond de la cabine d'ascenseur passe au-dessous d'une distance prédéterminée par rapport au fond de la fosse de cage.
  5. Installation d'ascenseur selon l'une des revendications précédentes, comprenant un limiteur de déplacement mécanique, en supplément au dispositif parachute, susceptible d'être introduit dans la trajectoire de la cabine d'ascenseur.
  6. Installation d'ascenseur selon l'une des revendications précédentes, dans laquelle les moyens pour activer le dispositif parachute sont agencés dans la zone de la fosse de cage.
  7. Installation d'ascenseur selon l'une des revendications précédentes, dans laquelle activation a lieu par un limiteur de vitesse ou par un déclenchement à câble dormant.
  8. Installation d'ascenseur selon l'une des revendications précédentes, dans laquelle activation a lieu par voie électrique et/ou mécanique et/ou hydraulique et/ou pneumatique.
  9. Installation d'ascenseur selon l'une des revendications précédentes, dans laquelle activation a lieu quand les portes ou les volets servant d'accès à la cage dans la zone inférieure de la cage sont ouverts, alors que la cabine d'ascenseur se trouve à une hauteur prédéterminée.
  10. Procédé pour l'opération d'une installation d'ascenseur comprenant une cabine ascenseur mobile dans une cage d'ascenseur avec une fosse de profondeur réduite, et un dispositif parachute agissant sur le mouvement de déplacement de la cabine d'ascenseur et déclenchable par des premiers moyens d'activation, dans lequel par activation à l'aide de seconds moyens additionnels pour activer le dispositif parachute, il est défini un espace de protection temporaire sous la cabine d'ascenseur.
