Definitions
- the invention relates to an elevator device with a an elevator car movable with and a counterweight movable in the elevator shaft, whereby the speed of the elevator car or Counterweight by means of a Speed limiter device is monitored and the Speed limiter device at Excess speed of the elevator car or the Counterweight the elevator car or the counterweight stops using a safety gear.
- 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 Checked the guide rails at the catch point and the Surface can be processed.
- the evacuation of the Elevator passengers can only be carried out by specialist staff become.
- 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 the false triggers the safety gear can be avoided.
- the advantages achieved by the invention are in essential to see in the fact that the Safety gear is not triggered.
- the elevator passengers this will not cause extreme delays in the Elevator cabin suspended.
- the implementation of the Evacuation of elevator passengers no specialist staff necessary.
- the elevator car can be used after the buffer run can be moved manually to the neighboring floor, so that the elevator passengers leave the elevator car can.
- the mechanics of the safety gear and of the speed limiter and the guide rails spared.
- the safety gear is not used for buffer tests triggered the considerable effort to release the catch is spared.
- the safety gear is used for acceptance tests usually blocked, so with unusual Test runs no catch cases in the shaft end areas may occur. With the device according to the invention is security even with acceptance tests over the entire Shaft height guaranteed.
- Fig. 1 shows an elevator device with one in one Elevator shaft 1 movable elevator car 2, the one Rope 3 is connected to a counterweight 4.
- the rope 3 is in operation 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 device has a top floor with a top 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.
- 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.
- a locking lever 25 is at the fulcrum 15 with one Double lever 14 connected.
- the one side 14.1 of a double lever 14 after deflected above.
- the locking lever 25 deflected counterclockwise.
- Fig. 1 shows that started on the top floor Elevator car 2 on the way down, with a stop on the second lowest floor and then on the lowest floor is provided. If, for example the journey from the second lowest floor to the lowest Floor runs with less than overspeed and the elevator car 2 on the lowest floor is not stops, the elevator car 2 will continue on caught below by buffers 26.
- the can Safety gear 16 due to the inertia of the Speed limiter 13 and the governor rope 19 are triggered, the catch elements of the Wedge the safety gear 16 with the guide rails 7.
- At least one locking element 27 is also on the upper one Provided shaft end, if the upper shaft end also Has buffer.
- the Device according to the invention for evacuating Elevator passengers can also access an elevator facility be used with machine room.
- Fig. 2 shows details of the locking lever 25 and Locking element 27 formed locking device for locking the Safety gear 16 during buffer travel.
- the one with the undressed Lock lever 25 shown in line is shown capable where the elevator car is on the bottom floor stands.
- the one shown with a dash-dotted line Locking lever 25 is shown in the position where the Safety gear 16 is engaged.
- the movement of the Locking lever 25 is not by the locking element 27 blocked.
- the one shown with a broken line Locking lever 25 is shown in the position where the Elevator car 2 down the bottom floor has run over.
- the movement of the locking lever 25 will blocked by means of the blocking element 27.
- the movement of the connected to the locking lever 25 at the pivot point 15 Double lever 14 is also blocked. The trigger the safety device 16 is thus prevented.
