Definitions

  • the invention relates to an elevator system with a drive, which cooperates via a transmission means with an elevator car and a counterweight to move the elevator car and the counterweight by transmitting a force in an elevator shaft.
  • Elevator systems of this type usually have an elevator car which is movable in an elevator shaft or freely along a guide device. To generate the movement, the elevator system has a drive, which interacts via transmission means with the elevator car and a balance weight (also called a counterweight).
  • a balance weight also called a counterweight
  • FIG PCT Patent Application WO 99/43602 An example of a flat transmission elevator system is shown in FIG PCT Patent Application WO 99/43602 known.
  • the elevator car according to this patent application is moved by a drive, which on the Balance weight sits and moves in solidarity with the weight.
  • the system described has the disadvantage that the belt used as a transmission means does not have the optimum traction behavior achievable with certain other belt-type transmission means, and that the power supply to the drive motor as well as the transmission of signals from associated control and regulation devices must be made over long, flexible cables ,
  • Another elevator system with schwriemenartigem transmission means is from the PCT Patent Application WO 99/43592 known.
  • the drive is integrated in the counterweight, and a timing belt-like transmission means fixed in the elevator shaft serves to transmit the driving force between the counterweight and the elevator shaft. Since the elevator car and the balance weight depend on an actual suspension element separate from said timing belt transmission means, the drive and transmission means transmit only the differential force between the counterweight and the weight of the elevator car.
  • This system has the same disadvantages as described above and has the additional disadvantage that a toothed belt is used for the drive function and another means for the support function. Compared to a system where the drive and support functions are done by the same means, this system requires a larger number of pulleys or pulleys.
  • a different elevator system with timing belt-like transmission means is from the U.S. Patent 5,191,920 known.
  • the timing belt-like transmission means is stationary in the elevator shaft.
  • the drive unit is located on the elevator car or on the so-called load-receiving means.
  • WO2002 / 059028 discloses an elevator system having a drive which cooperates via a transmission means with an elevator car and a counterweight to move the car and the counterweight by transmitting a force in a hoistway.
  • a suspension a suspension order greater than 2: 1 is selected.
  • the drive is provided with a drive pulley and is carried by a support structure arranged at the top in the elevator shaft, as well as further deflection pulleys, which are necessary for the high suspension order.
  • the transfer means is guided via the drive pulley, via different deflection pulleys, via a carrying pulley of the elevator car and a carrying pulley of the counterweight.
  • WO 1999/43593 also sets itself the task of saving space and to allow the use of a smaller drive.
  • an elevator system with a 2: 1 elevator suspension with a flat belt-type transmission means is disclosed.
  • the transmission means is guided laterally of the cabin wall via a drive pulley of a drive, a deflection pulley arranged below the drive, and in each case a deflection roller of the car and a deflection roller of the counterweight.
  • the belts disclosed in the cited documents have certain disadvantages.
  • Flat belts have insufficient traction capability in elevator facilities with elevator cabins that are lightweight relative to the payload.
  • the problem with timing belts is that they do not slip on the drive pulley when the elevator car or counterweight is resting on its limit buffers due to a control failure.
  • the centering of the belt on the Riemenpulleys is not easy to implement. Special measures may need to be taken on the pulleys to prevent the belt from running out of the central position.
  • the object of the invention is thus seen to provide an improved elevator system of the type mentioned, which reduces or avoids the disadvantages of the known systems.
  • the elevator system comprises an elevator car, a drive, belt-like transmission means, preferably a V-ribbed belt, and a counterweight.
  • the drive is stationary and the transfer means cooperate with the drive to move the elevator car by transmitting a force.
  • V-ribbed belts - also called V-ribbed belts - are used.
  • Such a V-ribbed belt can advantageously be used as a frictional (adhesive) support and / or drive element (transmission means) for an elevator car with counterweight.
  • the V-ribbed belt allows, with similar running characteristics as a flat belt, by its shape a higher rope force ratio.
  • a high rope force ratio means that the tension in the belt pulley running (pulled) strand of the belt can be substantially higher than in the belt running from the belt pulley at the same time.
  • the V-ribbed belt 13 a plurality of longitudinally parallel wedge-shaped grooves 5 and V-ribs 6. These wedge-shaped grooves 5 and V-ribs 6 allow by their wedge effect a cable force ratio of more than 2 at a wrap angle of 180 degrees.
  • V-ribbed belt 13 it centers itself on the pulley driving or guiding it itself, preferably the V-ribbed belt 13 on the rear side (ie on the side which has no wedge-shaped grooves 5 or V-ribs 6) provided with a guide rib 2, as in Fig. 15 shown.
  • This guide rib 2 has the task in a counter-bending of the V-ribbed belt, that is, when this rotates a pulley with directed against the pulley belt back, to guide the V-ribbed belt in an existing in the running surface of the pulley guide groove.
  • the wedge-shaped grooves 5 of the V-ribbed belts 13 have a groove angle b of 80 degrees to 100 degrees.
  • the groove angle b is about 90 degrees.
  • This groove angle b is much larger than in conventional V-ribbed belts.
  • the larger groove angle b achieves a reduction of the running noise.
  • the self-centering property as well as an increased cable force ratio (defined above) are retained.
  • the V-ribbed belt 13 is on the backside, as in FIG Fig. 13 shown provided with a layer 4, which preferably has good sliding properties.
  • This layer 4 may be, for example, a fabric layer. For multiple suspended elevator systems this facilitates the assembly.
  • V-ribbed belt 13 is in Fig. 14 shown.
  • This V-ribbed belt has both wedge-shaped grooves 5 and ribs 6 applied longitudinally, as well as lateral grooves 3. These transverse grooves 3 enhance the bending flexibility of the V-ribbed belt so that it can interact with reduced diameter belt pulleys.
  • the transmission means in the longitudinal direction oriented tensile carrier 1 contains, from Metallic strands (eg steel strands) or non-metallic strands (eg made of chemical fibers) exist.
  • Such tension members 1 impart the required tensile strength and / or longitudinal rigidity to the transfer means according to the invention.
  • a preferred embodiment of the transmission means comprises tension members 1 made of Zylon fibers.
  • Zylon is a trade name of Toyobo Co. Ltd., Japan, and refers to manmade fibers of poly (p-phenylene-2,6-benzobisoxazole) (PBO).
  • the tension members 1 should be embedded in the V-ribbed belt so that adjacent fibers or strands do not touch each other.
  • the ideal is a degree of filling, d. H. a ratio between the total cross section of all tension members and the cross section of the belt, proven by at least 20%.
  • Fig. 16 shows an embodiment of the V-ribbed belt 13, which is likewise suitable as transmission means for elevator systems.
  • tensile carrier of metallic or non-metallic strands here forms a flat tension layer 51 the core of the V-ribbed belt 13, said tension layer 51 extends substantially over the entire belt length and the entire belt width.
  • the tension layer 51 can consist of an unreinforced material layer, for example of a polyamide film, or be formed of a film reinforced with synthetic fibers.
  • Such a reinforced film could, for example, contain the aforementioned Zylon fibers embedded in a suitable plastic matrix.
  • the tension layer 51 gives the flat belt the required tensile and creep resistance, but is also sufficiently flexible to withstand a sufficiently high number of bending operations when deflecting around a belt pulley.
  • the V-ribbed layer 53 can be made, for example, of polyurethane or of an NBR elastomer (nitrile butadiene rubber) and is connected over the whole or part of the surface, directly or via an intermediate layer, to the tension layer 51.
  • the back side of the V-ribbed belt has a cover layer 54 connected to the tension layer 51 like the V-ribbed layer, which is advantageously designed as a sliding covering.
  • Intermediate layers may be present between said major layers to provide the necessary adhesion between said layers and / or increase the flexibility of the transfer medium.
  • This provided with a full-area tension layer V-ribbed belt can also be as already associated with Fig. 15 have described guide rib.
  • FIG. 17 another transfer means which can be used in elevator systems is shown, which is suitable for the solution of the task according to the invention.
  • the flat belt contains at least one flat tensile layer 51 in the core, which, for example, is consists of an unreinforced polyamide film, or of a plastic film reinforced with chemical fibers embedded in the plastic matrix.
  • This tension layer 51 gives the flat belt the required tensile and creep resistance, but is also sufficiently flexible to withstand a sufficiently high number of bending operations when deflecting around a belt pulley.
  • the flat belt 50 also has an outer, front-side friction layer 55, for example made of an NBR elastomer (nitrile butadiene rubber), as well as an outer, back-side cover 54, which, depending on the elevator system, is designed as a friction or sliding coating.
  • Intermediate layers 56 may be present between said main layers to provide the required adhesion between said layers and / or to increase the flexibility of the flat belt.
  • friction layers are available with coefficients of friction of 0.5 to 0.7 compared to steel pulleys, which are also very resistant to abrasion.
  • the lateral guidance of the flat belt 50 is usually, as in Fig. 18 represented, ensured by mounted on the pulleys 16 flanges 57, possibly in combination with a crowning of the pulley treads.
