Definitions
- the invention relates to an elevator device with an in an elevator shaft movable elevator car and with a movable in the elevator shaft counterweight, wherein the speed of the elevator car by means of a Speed limiter device is monitored and the Speed limiter device at Overspeed of the elevator car the elevator car shut down by means of a safety gear, with a Locking device is provided, which in a buffer drive the elevator car, the safety gear of the elevator car locks.
- a disadvantage of the known device is that the elevator car must be released from the catch.
- the Safety gear must be reset and the Guides checked at the trap and the Surface to be edited.
- the evacuation of Elevator passengers can only be carried out by qualified personnel become.
- 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 device by means of false alarms the safety gear can be avoided.
- Fig. 1 shows an elevator device with a in a Elevator shaft 1 movable elevator car 2, which has a Rope 3 is connected to a counterweight 4.
- the rope 3 is in operation by means of a traction sheave 5 a Drive unit 6 driven.
- Elevator car 2 and Counterweight 4 will be by means of the shaft height extending guide rails 7 out.
- the Elevator device has a top floor with a Top floor door 8, a second upper floor with a second upper floor door 9, more floors with further floor doors 10 and a lowest floor with a lowermost floor door 11.
- a shaft head 12 is the drive unit 6 and a Speed limiter 13, which arranged the Speed of the elevator car 2 monitored and at Overspeed stops the elevator car 2.
- the endless governor rope 19 is by means of a in a Well pit 20 arranged deflection pulley 21 tensioned, wherein a roller axle 22 at one end at a pivot point 23rd hinged and the other end carries a tension weight 24.
- a locking lever 25 is at the pivot point 15 with the one Double lever 14 connected.
- the locking lever 25 When triggered, as above mentions one side 14.1 of a double lever 14 after deflected above. At the same time, the locking lever 25th deflected in the counterclockwise direction.
- Fig. 1 shows the started on the top floor Elevator car 2 on the way down, with a stop on the second lowest floor and then on the the lowest floor is provided.
- the ride from the second lowest floor to the lowest Floor runs at less than overspeed and the elevator car 2 on the lowest floor not stops, the elevator car 2 on their onward journey to collected from buffers 26 below.
- a blocking element 27 which controls the movement of the Lock lever 25 blocked as soon as the elevator car 2 or the counterweight 4 the lowest floor down overruns.
- the upper blocking element 27 prevents a triggering the safety gear 16 at the upper end of the shaft.
- the Blocked locking lever 25 blocks the one double lever 14th and via the linkage 18 the other double lever 14. Die Triggering the safety gear 16 is thus prevented.
- At least one blocking element 27 is also at the top Shaft end provided if the upper shaft end also Buffer has.
- Fig. 1 shows a machine room-less elevator device.
- the Inventive device for the evacuation of Elevator passenger can also access an elevator be applied with engine room.
- Fig. 2 shows details of the locking lever 25 and Locking element 27 formed locking device for locking the Safety catch 16 during buffer travel.
- the one with undressed Line locking lever 25 is shown capable of at the elevator car on the lowest floor stands.
- the dash-dotted line Lock lever 25 is shown capable of in the Safety gear 16 is engaged.
- the movement of the Locking lever 25 is not by the blocking element 27 blocked.
- the broken line Lock lever 25 is shown capable of in the Elevator car 2 the lowest floor down has run over.
- the movement of the locking lever 25 is blocked by the blocking element 27.
- the movement of the connected to the locking lever 25 at the pivot point 15 Double lever 14 is thus blocked.
- the trigger the safety gear 16 is thus prevented.
