Definitions
- the invention relates to a safety device for an elevator with a movable in an elevator shaft Elevator car and a movable in the elevator shaft Counterweight, being a the speed of Elevator car or counterweight monitoring Speed limiter is provided at Over speed the elevator car or that Counterweight actuating trigger mechanism actuated.
- From JP2000219450 is a device for Triggering one arranged on an elevator car Safety gear with wedges become known.
- On Governor rope one the speed of the elevator car monitoring speed limiter is in Connection with one arranged on a first axis first lever. If the elevator car overspeeds the governor rope is blocked, the first lever because of the relative movement of the elevator car compared to that Limiter rope rotates the first axis.
- On A second lever is arranged on the first axis Connected to the safety gear and by means of Rotational movement of the first axis the wedges of the Safety gear engages.
- a disadvantage of the known device is that the tension spring the trigger mechanism in the starting position holds until the governor rope overcomes the spring force. A second catch immediately following the first catch is not feasible with this trigger mechanism.
- the invention seeks to remedy this.
- the invention as characterized in claim 1 solves the problem to avoid the disadvantages of the known device and to create a facility by means of which Safety gear of an elevator car or one Counterweight can be engaged in any case.
- the advantages achieved by the invention are in essential to see that the security of Elevator passengers can be significantly improved.
- the after a catch triggered by the governor rope ensures that the safety gear at a through the counterweight triggered pulse is re-engaged.
- the Trigger mechanism according to the invention causes that afterwards the wedges are immediately reinserted. Further It is advantageous that the previous construction of the Trigger mechanism is still usable and only with additional elements must be added. Another Certification is not necessary.
- Fig. 1 shows an elevator with one in an elevator shaft 1 movable elevator car 2 with a rope 3 with a counterweight 4 is connected.
- the rope 3 is in Operating case by means of a traction sheave 5 Drive unit 6 driven.
- Elevator car 2 and Counterweight 4 are by means of the shaft height extending guide rails 7 out.
- the elevator system has a top floor with a top floor Floor door 8, a second top floor with a second top floor door 9, further floors with further floor doors 10 and a lower floor with a lowest floor door 11.
- a shaft head 12 is the drive unit 6 and a Speed limiter 13 arranged the Speed of elevator car 2 monitored and at The elevator car 2 stops at excessive speed.
- ever Side of the elevator car 2 is a double lever 14, 14.1 provided that is hinged to a fulcrum 15, 15.1.
- Safety gear 16, 16.1 is by means of a first linkage 17,17.1 with one side of the double lever 14,14.1 connected, one side of the first double lever 14 with a governor rope 19 of the speed limiter 13 is connected.
- the other side of the first double lever 14 is by means of a second linkage 18 with the second Double lever 14.1 connected. If one side of the first Double lever 14 moves up, so the Safety gear 16,16.1 indented, with the Guide rail 7 wedging locking elements Stop elevator car 2 in an emergency.
- the elevator car 2 drives the governor rope 19 by means of the first double lever 14. If the speed is too high The elevator car 2 is blocked by the speed limiter 13 the governor rope 19. This makes the first double lever 14 deflected upwards and the second double lever 14.1 actuated, the safety gear 16,16.1 on both sides of the Elevator car 2 is engaged.
- the endless limiter rope 19 is by means of a Pit 20 arranged deflection roller 21 tensioned, wherein a roller axis 22 at one end at a pivot point 23 is articulated and carries a tension weight 24 at the other end.
- the first double lever 14 has one Cantilever 26 on which a bolt 27 is arranged.
- the Bolt 27 locked to one on a support frame 28 arranged retaining spring 29, which ensures that Rope vibrations or inertial forces of the governor rope 19 do not operate the first double lever 14.
- the first Pivotal point 15 mounted first double lever 14 has one first leg 14.01, which is articulated on the limiter rope 19 and a second leg 14.02 on which the second Linkage 18 is articulated. On the first leg is 14.01 also the first linkage 17 articulated, which as a catch wedge 30 trained locking element actuated.
- the second double lever articulated at the second pivot point 15.1 14.1 has a first leg 14.11 on which the first linkage 17.1 is articulated, that as a catch wedge 30.1 trained locking element actuated.
- a second Leg 14.12 of the second double lever 14.1 is articulated connected to the second linkage 18.
- a tense Tension spring 31 is at one end with the second leg 14.12 and at the other end with the support frame 28 of the elevator car 2 connected. The force emanating from the tension spring 31 can the first held by means of retaining spring 29 Do not operate double lever 14 during normal operation.
- Fig. 3 shows the trigger mechanism 25 when catching, the locking elements wedging with the guide rail 7 30.30.1 shut down elevator car 2 in an emergency.
- blocked limiter rope 19 becomes the first double lever 14 and the second double lever 14.1 in one with the arrows P0, P1 symbolized rotary movement offset, the first Double lever 14 is released from the retaining spring 29 and the wedges 30,30.1 in the arrows P01, P11 symbolized direction to be moved and with the Wedge the guide rail 7.
- Fig. 4 shows an embodiment of the Trigger mechanism.
- the double lever 14 is on a housing 28.1 arranged, which is arranged on the support frame 28.
- the Trigger mechanism compact.
- the tension spring is also 31 visible together with the retaining spring 29.
- Fig. 1 shows a machine room-less elevator system.
- the Device according to the invention for stopping the Elevator cabin can also be used on an elevator system Machine room can be applied.
- the trigger mechanism 25 can also be applied to the counterweight 4 be applied.
