Definitions

  • the present invention relates to an elevator with two drives each with a traction sheave and with suspension cables, which over the Traction sheaves are guided and with an elevator car and one Counterweight are operatively connected.
  • a modular elevator is known from EP 0 846 645, in which two to expand the range of services Drive modules can be used.
  • the two drive modules enable operation with 1: 1 or 2: 1 suspension.
  • the elevator according to the invention is characterized in that a only common set of suspension cables is needed, which over both traction sheaves of the two drives is guided. Thereby two rope end fastenings with rope end fittings, springs, Rope plates and supports.
  • rope clamp which, determined by the Elevator controls that have open or closed states can.
  • the rope clamp is operated by a servomechanism actuated and their functions can be reproduced as often as required.
  • the rope clamp In a disposition with a looped cab and 1: 1 suspension the rope clamp can preferably be located below the cabin to be ordered.
  • the rope clamp can preferably at a stationary location, for example in the Shaft head can be arranged.
  • the rope clamp is designed so that it is closed Condition of the carrying ropes led through the rope clamp absolutely holds tight and two functional from the single suspension cable set forms independent suspension cable sets.
  • the carrying ropes have a detectable marking by means of which is a shift of the elevator car from the middle of the Suspension ropes are recognized.
  • the detector can be placed anywhere, but will preferably in the cable clamp itself or in its immediate vicinity Environment arranged.
  • the cabin is only one on the drive level above the route only pulley needed, which also, as a replacement for one Rope clamp, which can be equipped with a brake, which both the pulley and the one placed over the pulley Holding ropes holds.
  • the brake can be electromagnetic or be operated servomechanically.
  • FIG. 1 shows a first drive with 1 and the associated one Traction sheave designated 1.1. Are over the traction sheave 1.1 Carrying cables 1.2 out, on which a counterweight 1.4 and over a sprung rope end attachment 1.3 attached to a cabin 3 are.
  • a second drive 2 with a traction sheave 2.1 has suspension cables 2.2, a second spring-loaded cable end attachment 2.3 to the cabin 3 and a counterweight 2.4. This elevator presents the known and commented prior art.
  • the elevator in FIG. 2 has one for two drives 1 and 2 single set of suspension cables 4, which over both traction sheaves 1.1 and 2.1 are listed. Loop under the common suspension cables 4 the cabin 3 via two pulleys 5 and 6. For a permanent Equal positioning of the counterweights 1.4 and 2.4 relative to each other, the two drives 1 and 2 must always be together run exactly in sync. This permanent synchronous running of the drives 1 and 2 together requires extensive and costly Control and sensor technology and places high demands on accuracy and reliability of the corresponding technical Additional equipment. According to the law of probability you can therefore malfunctions occur more frequently than with conventional dispositions.
  • Detector 10 and marker 9 can also be in the form of a unit a conventional incremental encoder device provided and with a pulley 5 or 6 or 11, 12 or 15 can be combined.
  • an incremental encoder device of the type provided the path, direction and speed of a spinning Deflection pulley 5, 6, 11, 12 or 15 and thus also the drive cables 7 be included.
  • the cable clamp 8 is only opened when a drive 1 or 2, e.g. as a result of a control error or in the event of a failure component connected to the drive, no longer functional is. Then the rope clamp 8 is controlled by one superordinate, not shown monitoring logic by means of a conventional servo drive, also not shown opened (Fig. 4). If there is an occupied cabin 3 in the event of failure a drive, e.g. of drive 2, not on one floor is located, it is now possible to still use the cabin 3 functioning drive 1 to drive on one floor.
  • the Controlling this process is a subfunction of one here evacuation control explained in more detail. When executing or after completing such an evacuation trip, one is shown Situation as shown in Fig.4.
  • a leveling trip is also without detector 10 and Marking 9 possible.
  • the Cabin 3 for example, with drive 1 and smaller Speed moves up until the counterweight 1.4 den touched the appropriate buffer and pressed something.
  • the feedback of the buffer contact switches drive 1 and the second one off Drive 2 now proceeds in the same way until the second counterweight 2.4 second buffer contact actuated.
  • the cable clamp 8 can be closed and the Normal operation can be resumed.
  • Putting one on Counterweight 1.4, 2.4 on a buffer can also be used Motor control can be perceived, which then becomes a buffer contact would be superfluous.
  • the rope end fastenings 1.3 and 2.4 are on a stationary one Point, for example arranged in the shaft head.
  • the pulleys 5 and 6 are placed on the side of the cabin 3 at the bottom.
  • Through the 2: 1 suspension will be two more pulleys 11 and 12 required, which are preferably also installed in the shaft head.
  • the cable clamp 8 with the detector 8 must be at this point be arranged stationary between the deflection rollers 11 and 12.
  • At 13 and 14 are fictional Rope end fastenings indicated in the shaft ceiling. With that only shown how the disposition without rope clamp 8 look would, or what the dispositive effect of the closed Rope clamp 8 causes.
  • a 2 1 disposition without looping the Cabin 3 shown.
  • the two pulleys 5 and 6 are on the Cabin 3 arranged.
  • At the drive level is instead of the two Deflection rollers 11 and 12 in Figures 5 and 6, only a single one Deflection roller 15 is provided.
  • a blocking the pulley 15 and deblocking device is simplified here as a brake shown with brake shoe 16, spring 17 and spool 18.
  • Blocking and unblocking device can also be a servo-operated Device are provided which in one without energy expenditure which can remain blocked or unblocked.
  • the deflection roller 15 can the previously mentioned incremental encoder device contain.
  • the design of the cable clamp 8 can be for the intended Purpose of the application to be constructed very simply, since they are used in the described functions only operated when the elevator is at a standstill is and therefore does not perform a dynamic braking function.
  • the Servomechanics for operating the cable clamp 8 can for example as an electromagnetic toggle mechanism or as Motor spindle to be run here only the most important Opportunities to name.
  • the cable clamp 8 should be for the described function in both positions, open and closed, remain without energy supply.
  • the detector 10 and the marking 9 on the support cables 7 can be carried out according to one of the known principles.
  • the detection The mark 9 on the support cables 7 can therefore, for example with optoelectronic, magnetic or inductive means be carried out.
