Definitions

  • the present invention relates to a guide device for an elevator system, to an elevator system and to a method for operating an elevator system.
  • Linear drives or linear motors are used to generate linear movements.
  • linear motors can be imagined as a one-level rotary motor.
  • Such a linear motor comprises a primary part and a secondary part.
  • the primary part is comparable with a stator of a rotary motor and can, for example, be designed as a current-carrying coil.
  • the secondary part, or reaction part is comparable with a rotor or rotor of a Rotati onsmotors and can be designed as a magnet, for example. As a permanent magnet or solenoid.
  • the primary part or the secondary part of the linear motor is designed as a stationary element, while the other part of the linear motor is movable and can be moved along the stationary element.
  • the primary part is stationary.
  • Linear drives can also be used as drives for elevator systems for moving cars in a hoistway.
  • a multi-car elevator system for example, several cars can be moved independently of one another in an elevator shaft with such linear drives. It is also possible that the cars change between different elevator shafts.
  • the stationary part of the linear drive usually runs together with a guide rail over the entire delivery height of the elevator system.
  • the other part of the Linear drive, which interacts with the stationary part, is located on each of the cars.
  • an elevator system with a linear drive in which the stationary part of the linear drive is designed as a rail with rack structure. Brake coils are applied to the teeth of the rail, by means of which a car can be braked by interaction with the car-side part of the linear drive.
  • a guide device can be used in an elevator system with at least one car movable along the guide device by means of a linear drive, wherein the guide device has a guide rail on which the at least one car can be guided and a stationary part of the linear drive.
  • the guide means at least partially along the guide means extending guide means which are arranged such that at along them a car can be moved by means of an alternative drive different from the linear drive on.
  • the guide means allow the use of a car with an alternative drive, which is independent of the linear drive.
  • this car with alternative drive may be an additional car that is not used in regular operation.
  • a failure of the linear drive which is in particular an electric linear drive or linear motor
  • there is still the possibility of a car eg. A service car basket for assembly work or a car to evacuate people to the Move to the defective section of the linear actuator.
  • a stuck car with a service car or a rescue car can be towed.
  • Such failures can occur, for example, in a part of the stationary part of the linear drive.
  • the guide means are formed on the guide rail. This allows a particularly space-saving arrangement.
  • the guide means can, for example, be mounted prior to installation of the guide rail to this and then installed together with this in a hoistway. In addition, the assembly time can be reduced.
  • the guide means on a rail which allows a positive contact with the alternative drive.
  • a rail is easy to manufacture and, on the other hand, it can also be easily mounted on the guide rail.
  • a positive contact with the alternative drive can be produced by a positive contact in a particularly simple manner.
  • the rail has alternating teeth and gaps.
  • the rail can therefore be a kind of rack.
  • Such a rail is, for example, particularly low maintenance. This is particularly advantageous because this rail is not used during normal operation of the elevator.
  • the alternative drive has at least one toothed wheel and / or a chain for producing a positive contact with the rail.
  • a gear may, for example, be a pinion, which is in operative connection with a motor of the alternative drive.
  • a contact between rail and alternative drive can be made particularly easy in this way.
  • a chain which, for example, acts over a certain distance on the rail, in particular on the teeth of the rail, on the other hand enables a more effective contact between rail and alternative drive.
  • the guide means are formed of a different material from the guide rail.
  • the guide rail is usually made of aluminum, for example in the form of an extruded profile
  • the guide means may be made of steel or other material which is more resistant to wear than aluminum. This is on the one hand advantageous because between the guide means and the alternative drive preferably a mechanical contact is necessary, in particular, for example, between a pinion and the guide means formed as a rack, while the guide rail only serves as a support for roles of the car.
  • the guide means offers the possibility to use the guide means as an attack surface for a safety gear of the cars. Since safety gears usually have a covering that damages the rail on which it acts, it makes sense not to let a safety gear act on the guide rail, but on a more wear-resistant further rail.
  • the guide means and the guide rail may be formed of the same material. This is, for example, then advantageous if already the guide rail is formed of a wear-resistant material or if the guide means should not be used as a target surface for a safety gear.
  • the guide means along the guide means on several, each spaced-apart parts. This allows for a simpler installation of the guide means and on the other hand a simpler exchange of individual sections, for example.
  • a section is strongly closed by a safety gear. In particular, then not the entire guide rail must be replaced.
  • An elevator system according to the invention has a guide device according to the invention and at least one car which can be moved along the guide device by means of a linear drive. It should be noted at this point that an elevator system according to the invention, in addition to a guide device according to the invention as a second guide device, can also have a guide rail only with a stationary part of a linear drive. However, it is also possible and also advantageous if an elevator system, if a second guide device is necessary, has a further guide device according to the invention.
  • the at least one car has a safety device, which is arranged so that it can engage the guide means.
  • the elevator system has a car with an alternative drive different from the linear drive, by means of which the car can be moved along the guide means. It is advantageous if the car with the alternative drive is different from the at least one car which can be moved by means of the linear drive.
  • a method according to the invention serves to operate an elevator system with at least one car which can be moved along a guide device by means of a linear drive.
  • a car is moved by means of an alternative drive, which is different from the linear drive, along guide means which are encompassed by the guide device and extend at least partially along the guide device.
  • the moving by means of the alternative drive car is used in at least partial failure of the linear drive.
  • the at least one car on a safety gear wherein the guide means are used as an attack surface for the safety gear.
  • Figure 1 shows a guide device according to the invention in a preferred embodiment in a perspective view.
  • Figure 2 shows a guide device according to the invention in a preferred embodiment in side view.
  • Figure 3 shows a guide device according to the invention in a preferred embodiment with an alternative drive.
  • Figure 4 shows guide device according to the invention in a preferred embodiment with another alternative drive.
  • FIG. 5 shows a lift system according to the invention in a preferred embodiment in a side view.
  • FIG. 1 shows a section of a guide device 100 according to the invention in a preferred embodiment, schematically and in a perspective view.
  • a guide device can be arranged in an elevator shaft of an elevator system and extend over the full height of the elevator shaft.
  • Such an elevator system can, for example, also have several elevator shafts, each with a plurality of cars, which are moved by means of linear drives. Accordingly, a guide device according to the invention can then be provided in each elevator shaft.
  • the guide device 100 has a guide rail 110 which, for example, may be made of aluminum. In particular, this may be an extrusion molding Profile made of aluminum.
  • a guide rail 110 On the guide rail 110 are usually guide rollers of a car, which is moved in the elevator shaft up and down to.
  • the guide device 100 has a stationary part 120 of a linear drive.
  • This stationary part 120 can be, for example, adjacent permanent magnets or coils.
  • a corresponding counterpart to the stationary part 120 of the linear drive is mounted at a suitable location on a car.
  • the exact configuration of the linear drive is not important in the context of this invention.
  • the guide device 100 comprises guide means 130, which is designed for example as a rail.
  • the rail 130 alternately has teeth 131 and gaps.
  • the rail 130 is attached to the guide rail 110, for example. Screwed.
  • FIG. 2 shows a side view of a guide device according to the invention.
  • the configuration of the rail 130 is shown as a juxtaposition of a plurality of similar parts 132. Between two adjacent parts 132 each have a gap or a gap 133 is formed. Through these gaps 133, a different thermal behavior of the rail 130, in particular the length extension, can be taken into account by the guide rail 110.
  • the gaps 133 may also be designed as expansion joints.
  • the formation of the rail 130 as a plurality of parts 132 allows easier and faster mounting of the rail 130 to the guide rail 110.
  • individual parts 132 can be replaced more easily than a long rail. This is particularly advantageous if the rail 130 is used as a contact surface for a safety gear of a car.
  • the rail 130 is, for example, off Steel, since steel is much more resistant to wear than the aluminum of the guide rail 110.
  • FIG. 3 shows a guide device according to the invention in a preferred embodiment with an alternative drive.
  • the part of the guide device shown comprises the guide rail 110 and the rail 130 and corresponds to the illustration in FIG. 2.
  • an alternative drive 140 which by way of example has two gears 150, which are connected to a chain 151.
  • one of the gears 150 by means of a motor, eg. An electric motor driven.
  • a positive contact between the alternative drive 140 and the rail 130 can be made.
  • FIG. 4 shows a guide device according to the invention in a preferred embodiment with another alternative drive.
  • the alternative drive 140 in FIG. 4 differs from that in FIG. 3 in that only one gear 150 is provided, for example a pinion.
  • the positive-fit contact between the alternative drive 140 and the rail 130 is produced directly by the gear 150 and the teeth of the rail 130.

  • the alternative drives are each mounted on two opposite sides of the top and bottom of the car 200.
  • the car 200 can be moved along the rails 130 and thus along the guide means.
  • a guide of the car 200 can be done as usual by guide rollers which rest against the guide rails 110.
  • the stationary part of the linear drive not visible in FIG. 5 is not required for a movement of the car 200 by means of the alternative drives 140.
  • the car 200 can be used in particular as a service car when a defect in the stationary part of the linear drive is present and a conventional car that can only be moved by means of the linear drive, no longer usable or no longer movable.
  • a car 200 does not necessarily have to have four alternative drives, it is also conceivable to provide only two or even only an alternative drive. Accordingly, under certain circumstances, it may also be sufficient to provide only one guide device according to the invention in the elevator shaft and to provide a second guide device, if necessary at all, only as a guide rail with a stationary part of the linear drive.
