Definitions

  • the invention relates to a device for stopping an elevator system consisting of one, the Speed of a carrying rope with a Counterweight connected elevator car monitoring Speed limiter, the movement of the Elevator cabin by means of a limiter rope on the Speed limiter is transferable, the at Overspeed of the elevator car in the downward direction a arranged on the elevator car safety gear actuated, wherein the safety gear, the elevator car shuts down.
  • a disadvantage of the known device is that the monitoring and shutdown of the elevator car only in the downward direction takes place.
  • a disadvantage of the known device is that the device is not suitable for retrofitting.
  • the invention aims to remedy this situation.
  • the invention as characterized in claim 1 solves the task to avoid the disadvantages of the known device and to create a facility that the elevator car in the Upstream and downlink monitored and shut down in an emergency.
  • the advantages achieved by the invention are in essential to see that the release forces after a Stopping in the upward direction are very low.
  • the Release from the catch is with the existing propulsion the traction sheave possible, which in particular machine room-less elevator systems is of importance.
  • no in the inventive device generates additional load on the drive and excessive Delays excluded.
  • With the inventive Facility may be lift systems without any changes to the Lift cabin can be easily retrofitted.
  • Figs. 1 to 4 is 1 in one not illustrated elevator shaft movable elevator car denoted by means of a via a traction sheave 2 guided carrying cable 3 connected to a counterweight 4 is.
  • To monitor the speed of the elevator car 1 or the counterweight 4 is for example a on the Pendulum lever principle working speed limiter 5 provided, wherein the movement of the elevator car 1 and the Counterweight 4 by means of a limiter 6 on the Speed limiter 5 is transmitted.
  • the Limiter rope 6 extends over the entire shaft height and is at the lower end of the shaft by means of a guide roller. 7 deflected and stretched and over at the upper end of the shaft a pulley of the speed limiter 5 out.
  • the ends of the Beskyrseiles 6 are rotatably on the elevator car 1 stored first trigger 8 moored, the one at the elevator car 1 in an emergency arranged catcher 9 actuated. After releasing the Elevator car 1 from the catch sets a return spring 10th the first trigger lever 8 and the safety gear 9 back.
  • a boom 11 is arranged, through the the governor rope 6 is guided. Close to the boom 11 carries a fixed to the governor rope 6 connected Spring base 12 a compensation spring 13, with their Spring force against the boom 11 presses. Cantilever 11, Spring base 12 and compensating spring 13 form a elastic rope coupling, the different rope strains can take up between the support cable 3 and 6 Besky.
  • a trigger mechanism 14 of the speed limiter. 5 actuated at overspeed of the elevator car 1 in Upward direction a rope brake 15.
  • FIG. 2 shows details of the speed limiter 5, the trigger mechanism 14 and the rope brake 15.
  • Das Limiter rope 6 is via a on a first axis 16th rotatably mounted pulley 17 with a rope groove guided.
  • the first axis 16 is of a housing 18th carried.
  • On the pulley 17 is a locking ring 19 with Sperrkranzähnen 20 and a cam 21 with cam 22nd arranged.
  • the housing 18 carries a second axis 23, on a pendulum lever 24 rotatable with a spherical roller 25 is stored.
  • At normal speed follows the Spherical roller 25 formed by the cam 22 Cam track of cam wheel 21.
  • At overspeed can the pendulum roller 25 due to the inertia of the Swing lever 24 of the cam track not to follow.
  • a first lug 26 is arranged at Normal speed of the elevator car 1 between two Sperrkranzzähne 20 is immersed when the pendulum roller 25 on a cam 22 stands and the off the track of the Sperrkranzzähne 20 is lifted when the pendulum roller 25th between two cams 22 is.
  • the Elevator car 1 in the downward direction remains the first nose 26th between two Sperrkranzzähnen 20 are, with the right Flank of the following locking ring tooth 20 at the first Nose 26 is pending and the locking ring 19 and thus the Sheave 17 blocked. Due to the relative movement of Elevator car 1 with respect to the blocked governor rope 6 is by means of the first trigger lever 8, the safety gear 9 engaged and the elevator car 1 to the Fixed guide rails.
  • an operating lever 27 At the opposite end of the spherical roller 25 of the Swing lever 24 is an operating lever 27 at one third axis 28 of the pendulum lever 24 rotatably disposed.
  • the operating lever 27 is by means of a Retaining device, for example by means of a Schnäppers relative to the pendulum lever 24 in a rest position held.
  • a second nose 29 of the operating lever 27th appears at normal speed of the elevator car. 1 between two ratchet teeth 20 when the pendulum roller 25 stands on a cam 22 and is off the track of Sperrkranzzähne 20 is lifted when the pendulum roller 25th between two cams 22 is.
  • the Brake shoe 34 moves down and is using the Compression spring 33 against at least one of the housing 18th arranged counterjaw pressed 35, the between the Baking 34, 35 running limiter rope 6 is braked.
  • the Braking force exerted on the governor rope 6 slows down the braking force Elevator car 1 and the counterweight 4 off gently and is depending on the spring force of the compression spring 33, the Surface of the jaws 34, 35 and from the surface of the Limiter Ropes 6.
  • the braking takes place via limiter rope 6, spring base 12, balance spring 13 and boom 11 on the counterweight 4.
  • 3 and 4 show a device for stopping the Elevator car 1 at overspeeding in the upward direction by means of a cable brake 15 acting on the carrying cable 3.
  • the movement of the second trigger lever 31, 32 is by means of a Bowden cable 36 on the second release lever 31.1, 32.1 of the rope brake 15 at the same functioning the rope brake 15 transmitted.
  • Speed limiter 5 used as a rope brake become.
  • this variant is at overspeed the elevator car 1 in the upward direction of the locking ring 19th by means of a further arranged on the pendulum lever 24 nose blocked. Due to the friction of the governor rope 6 in the specially trained rope groove of the blocked Sheave 17 creates a sufficiently large braking force, if the governor rope 6 is biased very high.
  • the monitor for overspeed of the Elevator car 1 used in the downward direction Speed limiter 5 with the pendulum lever 24 and the first nose 26 can easily be used to monitor Overspeed of the elevator car 1 in Upstream be retrofitted.
  • the cultivation of the Operating lever 27 and the rope brake 15 is light makeable.
