Definitions

  • the invention relates to elevator systems for buildings with a car, which has a traction device is connected to a drive mechanism.
  • Known elevator systems essentially consist on the one hand of an elevator shaft with guide rails, shaft doors, a cabin including safety gear and magnetic switch, a counterweight and information-providing devices and on the other hand a machine room of the machine as electric motors or hydraulic drives, a speed limiter, a control and a main switch. Solutions of this type are described, inter alia, in the publications EP 0 955 262 A1 (hydraulic elevator), EP 0 957 060 A1 (hydraulic rope elevator), DE 198 51 726 A1 (elevator with a spindle lifting rope drive), DE 199 02 853 A1 (passenger rope elevator), DE 298 14 744 U1 (elevator with drive) and DE 298 19 566 U1 (elevator).
  • Elevator systems of this type are distinguished by a complicated and complex structure. The effort is very uneconomical, especially for buildings with a small number of floors. For example, there are additional high costs for the tenants, so that the rental costs increase significantly.
  • the drives are connected to the cars.
  • Such solutions are listed inter alia in EP 0 614 843 A1 (drive device for a self-propelled elevator car) and DE 198 34 994 A1 (elevator system with integrated machine unit). No counterweights and traction devices are used in these elevator systems. However, guide rails and cabin frames are also required. The effort for coupling the drives and the guide rails and thus for the transmission of motion between the drive and the cabin increases.
  • EP 0 550 904 A1 pneumatic vacuum elevator system
  • the cabin is moved in a shaft via a pneumatic pressure change.
  • the technological structure of such an elevator can only be implemented in a very complex manner due to the airtight guides between the cabin and the shaft, which are particularly necessary.
  • the effort increases with the loads to be transported. Accordingly, high pressure differences in the shaft are necessary for large loads.
  • An air exchange must be ensured when the occupied cabin moves in the shaft. This is not the case with the pneumatic vacuum lift system described.
  • the invention specified in claim 1 is based on the problem of a Easy to create elevator for building that continues to stand out distinguishes that this is both under construction and in existing buildings can be easily installed or attached.
  • the tubular body in a self-supporting and supportive and / or load-bearing construction with a closed inner wall according to the Further development of claim 2 ensures a separate and independent of the building Design of the elevator system.
  • the elevator system can easily both inside as well as placed outside of a building. Another advantage is there in that the elevator systems are also installed in existing buildings can without affecting the statics of this building.
  • the tubular body is dimensioned so that it all results from the operation of the elevator absorbs horizontal and vertical forces.
  • the tubular body is an assembly that is largely independent of other on-site trades. The realization of the tubular body in particular from several parts ensures easier installation, preferably in existing buildings.
  • At least one opening between either the top of the cabin and the Inner wall of the tubular body or the cover plate of the cabin after the Further development of claim 3 ensures the air balance between the interior the cabin and the volume of the tubular body above it movement or when the cabin is stationary in the tubular body.
  • the opening must be so large that there is always a sufficient one when the cabin is occupied Air exchange is guaranteed.
  • Air exchange means compression and suction during the movements of the cabin.
  • the element in particular a seal between the bottom plate of the cabin and the Inner wall of the tubular body according to the development of the claim 6 secures a compressible air cushion to brake the movement of the cabin in the event of an unwanted draining or tearing of the traction device.
  • a seal between the bottom plate of the cabin and the Inner wall of the tubular body secures a compressible air cushion to brake the movement of the cabin in the event of an unwanted draining or tearing of the traction device.
  • An electric synchronous motor or servo drive as a drive mechanism for the Cabin in the tubular body according to the development of claim 8 is characterized by freedom from maintenance and favorable heat development. Such Drive mechanisms can be controlled so that even at low speeds large transferable torques can be achieved. This is a direct drive for them Movement of the cabin is given in the tubular body. Conventionally necessary Counterweights including their structural necessities are not necessary.
  • Sliding bodies and / or rolling elements on the one hand on the cabin and on the other hand between the cabin and the inner wall of the tubular body after the training of claim 9 improve the leadership of the cabin in the tubular body. Tilting movements of the cabin, especially when moving off, are largely avoided excluded, so that safe operation is given.
  • the encoder and the device for position measurement after the training of Claim 11 is the automatic function of the elevator system according to the invention ge waterproofrleistbar.
  • the controllable valve can also be connected to it be, so that the associated advantages are guaranteed.
  • an elevator installation for buildings 15 essentially consists of a tubular body 1, a car 2, a drive mechanism 4, a traction mechanism 3 and a control system.
  • 1 is a sectional side view of an elevator system in principle.
  • the tubular body 1 is arranged in or on the building 15 vertically extending over all floors 16 (representations in FIGS. 4 and 5). It consists of one part or several parts that are assembled, assembled and connected during installation or attachment from above or below.
  • the tubular body 1 has a closed inner wall. Furthermore, this is realized in a self-supporting and supporting and / or supporting construction. For this purpose, the tubular body 1 has a suitable ribbing and / or is provided with additional supporting construction elements.
  • the ribs or the construction elements are arranged lengthways, diagonally and horizontally. Both variants ensure a low use of material with the same stiffness and strength of the tubular body 1.
  • the tubular body 1 consists of a metal, in particular a steel, a plastic, in particular a laminate, or a glass-like material.
  • the tubular body 1 has a closable opening as an access door 9.
  • the tubular body 1 is closed in the lower region and a free space 6 is present between this closure 5 and the lowest opening 11.
  • a cabin 2 for the vertical transport of at least two people and an ambulance.
  • the cabin 2 is a self-supporting construction with a lockable cabin door 10, a base 7 and a cover plate 8.
  • the cross sections of the tubular body 1 and at least the base plate 7 of the cabin 2 are of the same design, in particular square or circular.
  • the cabin door 10 is designed such that it can be moved into the interior of the cabin 2 or between a double wall as a cabin wall.
  • the constructions necessary for this are known.
  • the drive mechanism 4 is located in the upper region of or on the tubular body / body 1.
  • the drive mechanism is arranged on or in the vicinity of the tubular body / s 1, the traction means 3 being deflected via rollers in each case becomes.
  • the drive mechanism 4 is an electric synchronous motor or electric servo drive. In the synchronous motor, the electrically generated excitation field rotates in the stator depending on the speed.
  • Permanent magnets are in the rotor and three-phase windings for generating the rotating field are attached to the stator.
  • a frequency converter is used to control the synchronous motor.
  • the drive mechanism 4 is connected directly or via a gear to a traction device 3 and the traction device 3 to the cover plate 8 of the cabin 2.
  • an unlinked, for example as a rope, or an articulated, for example as a chain, is used as the traction means 3.
  • the cab 2 can be moved directly up or down, depending on the control, via the drive mechanism 4 and the traction means 3.
  • the traction device 3 is wound on a shaft or runs from this.
  • the tubular body 1 simultaneously represents the guidance of the cabin 2.
  • the tubular Body 1 sliding body and / or rolling elements.
  • balls can be used, which are held in at least one correspondingly shaped cage, which in turn is attached to the cabin 2.
  • the tubular body 1 can be installed in or on a building 15 both as a separate device and as an additional self-contained elevator system.
  • existing access doors 9 can also be used. However, it must be ensured that a lock is present between the openings of the tubular body 1 and the access doors 9 (illustration in FIG. 3).
  • the openings of the tubular body 1 can be closed by means of sliding doors (illustration in FIG. 2). The sliding doors are guided on the tubular body 1.
  • the free space 6 between the termination 5 of the tubular body 1 and the bottom opening 11 via a controllable valve be connected to the environment.
  • the control of the valve is connected to a computer. This ensures that during a normal up and down movement, that there is no suction or compression in the interior of the tubular body 1 takes place.
  • the valve is closed as quickly as possible, so that it is present under the cabin 2 Air volume can be compressed.
  • Position securing elements are present. These are form-fitting or friction-locking elements, which releasably engage the inner wall of the tubular body 1 and on the Base plate 7 and / or the cover plate 8 of the cabin 2 are attached.
