Definitions

  • the invention relates to a braking device of an elevator car which brakes the elevator car at least when an inadmissibly high speed of the elevator car occurs.
  • Out JP06092568 is such a braking device in which a speed limiter with a pulley via a speed limiter rope activates a brake unit on an elevator car.
  • the speed governor rope circulates in the form of a closed loop, on the one hand, the pulley of the speed limiter arranged in the upper area of the car travel and, on the other hand, a cable deflection pulley present in the lower area of the car travel, one strand of the cable loop being coupled to an actuating element of the brake unit attached to the elevator car and thus to the elevator car is.
  • the lower Seilumlenktech is arranged vertically movable and loaded in the downward direction by a weight so that the cable loop is stretched by the lower SeilumlenkMIC.
  • a monitoring device with a detector monitors the position of this lower Seilumlenkusion to influence the elevator control in case of breakage or excessive elongation of theklasbe bayeauseils.
  • the invention has for its object to provide a braking device of the type described above, which does not have the disadvantages of the cited as prior art device.
  • a braking device for elevator cars is to be created in which, after a failure of the coupling between the speed governor cable and the brake unit of the elevator car, the elevator system does not remain in operation in a safety-related impermissible state.
  • the advantage achieved by the invention is essentially to be seen in the fact that the reliability of the elevator system is increased by an operating condition is avoided in a failure of the coupling (operative connection) between the traction means and the elevator car or the brake unit of the elevator car, in which the elevator car people are transported, although the prescribed fuse through the braking device is no longer functional.
  • the traction means of the braking device forms a Switzerlandstoffumlenkusionn circumferential closed loop, both ends of the traction means are fixed to a coupling element which simultaneously couples the traction means with the actuating element of the brake unit.
  • the coupling element has a weight that is sufficient in the case of failure of the coupling between the traction means and the elevator car to move the traction means together with the Switzerlandstoffumlenkimin in motion, so that the coupling element drops.
  • the monitoring device comprises a mounted in the lower Switzerlandstoffumlenkus detector which detects the coupling element, if this after a failure of the coupling between the traction means and the brake unit or the elevator car to the level of the detector has dropped.
  • the monitoring device comprises a detector mounted on the elevator car, which detects in normal operation whether the coupling element is in its normal position relative to the elevator car located, and signals a failure of the coupling between the traction means and the elevator car as soon as he no longer recognizes the coupling element.
  • the detector is a switch with galvanic contacts, which detects the presence of the coupling element by means of a mechanical probe element.
  • a reliable and easy to install braking device is achieved with a detector comprising a sensor that detects the presence of the coupling element without contact.
  • a detector comprising a sensor that detects the presence of the coupling element without contact.
  • inductive sensors, capacitive sensors or light sensors are used for this purpose.
  • the braking device according to the invention is designed such that the detector of the monitoring device is connected to an elevator control, which interrupts the operation of the elevator in the event of a detected failure of the coupling between the traction means and the brake unit or the elevator car.
  • the elevator control is designed so that it interrupts the operation of the elevator after the detected failure of said coupling only when the elevator car has reached a floor. This avoids that passengers unnecessarily remain trapped in the elevator car and need to be evacuated with outside help.
  • the attached to the elevator car 5 brake units 15 may be designed as a conventional elevator safety brakes.
  • brake wedges or eccentric discs are brought into frictional contact with the car guide rails 4 via an actuating lever 16 and a - not shown here - mechanical system of levers, whereupon the brake wedges or the eccentric discs due to the existing between them and the car guide rails relative movement and the friction effect in a position be brought in which they themselves or an intermediate brake body are pressed so strong against the car guide rails that the elevator car is braked.
  • the brake units 15 may, for example, also contain hydraulically actuated brake pistons, which press the brake plates against the car guide rail and thereby brake the elevator car.
  • the actuating lever 16 acts on valves that control the pressurization of the brake piston and thus the pressing of the brake plates against the guide rails.
  • these can slow down the travel of the elevator car in two or only in one direction of travel.
  • An activation system activates the brake units 15 in the event of an impermissibly high speed - hereinafter referred to as overspeed - or in other situations recognized by the elevator control 30, which require immediate and safe braking of the elevator car.
  • the activation system comprises a traction means 17 with two Anlagenstofftrumen extending parallel to the direction of travel of the elevator car, the traction means at least one upper Werstoffumlenkharimen 18 and a lower Werstoffumlenkusion 19 circulates and is connected at its two ends with a coupling element 23. This coupling element is coupled to the actuating lever 16 of the attached to the elevator car 5 brake unit 15 which is held in normal operation by a centering device 25 in its normal position.
  • a blocking device 20 which blocks the traction means when detected overspeed of the traction means 17 and the elevator car, or adjacent, generated by the elevator control 30 blocking signal, which depending on the embodiment of the blocking device blocking by direct braking of the traction means 17 or by blocking the upper Switzerlandstoffumlenkhari 18 can be done.
  • a pulling means 17 for the braking device for example, wire ropes, flat belts, toothed belts or link chains of all kinds are used.
  • the coupling element 23 of the traction mechanism 21 sinks with the strand of the traction means fixed to it in the direction of the lower traction sheave 19.
  • the coupling element 23 is designed sufficiently heavy for this purpose, so that its weight can move the traction means and the two Werschumlenkharin 18, 19 despite friction losses in motion.
  • This situation is in the lowest part of the Fig. 1 shown where the detector 27 shown as an electrical switch with a mechanical probe element 27.1 and the sunken coupling element 23 shown in dashed lines is.
  • the detector 27 signals the presence of the coupling element in its sunken position and thus the failure of said coupling between the coupling element 23 of the traction mechanism 21 and the elevator car 5 to the elevator control 30, which shuts down the elevator system, advantageously as soon as the elevator car has reached a floor.
  • Fig. 2 shows a second embodiment of the inventive braking device 2, in which the position of the coupling element 23 is monitored with respect to the elevator car 5 by a detector connected to the car 28.
  • a detector is used which detects the coupling element without contact, ie, which contains, for example, an inductively or capacitively operating sensor or an infrared light sensor.
  • the detector 28 signals the failure of said coupling to the elevator control, which stops the elevator system, preferably only in this embodiment of the braking device when the elevator car has reached a floor. It makes sense to alert the service organization responsible for the elevator installation at the same time.
  • Fig. 2 is already related to Fig. 1 mentioned centering device 25 particularly well recognizable, the operating lever 16 of the mounted on the elevator car 5 brake unit 15 is fixed in its normal position during normal operation of the elevator system to ensure that a strand of the circulating traction means 17 in the Normal operation moves synchronously with the elevator car up and down.
  • the centering of the actuating lever 16 in its normal position is realized in that a guided in a bore ball is pressed by a compression spring into a notch of a disc which is rotatable in solidarity with the actuating lever 16 about a common lever axis 26.
