Definitions

  • the invention relates to an elevator system.
  • the invention is based on an object To propose the elevator system of the type mentioned at the beginning, which does not have the aforementioned disadvantages and a Reduction of drive and / or braking torques enabled. It will be a slow or low gear translation allows.
  • One advantage is that it is small, light as well as inexpensive drive unit and brake unit can be applied. This also results from the Fact that the peripheral speed of the traction sheave the drive unit higher than the absolute Driving speed of the elevator is.
  • the elevator system is thus saving space. No machine room is needed.
  • Another advantage is the fact that the elevator system according to the invention both the Drive unit / brake unit as well as the traction device on the driven / braked will move.
  • Another advantage is the fact that forces and Accelerations are initiated upwards as well as downwards can. So it can be over 1 g in both directions be accelerated.
  • Another advantage of the whole shaft tense cabin is the stopping accuracy of the cabin. The means the vertical displacement of the cabin as a result Loading / unloading is significantly reduced.
  • the drive speed and the stopping accuracy are increased.
  • FIG. 1 shows one designed as an elevator car 1 moving element, which, preferably directly, with a revolving traction means 2, for example as a rope is formed, is connected.
  • the traction device 2 is on the Cabin 1 attached.
  • the cabin 1 travels up and down in an elevator shaft, not shown.
  • the traction device 2 is at one of its ends with the roof or upper frame 3 of the Cabin 1 attached. In this embodiment it is Traction means 2 at the other of its ends with the floor or lower frame 4 of the cabin 1 attached.
  • the traction device 2 is not fixed in the elevator shaft, for example on a wall of it, attached.
  • the traction device 2 thus moves together with the cabin 1. Apart from the elasticity of the There is therefore no relative movement in traction means 2 in Direction of travel between the traction mechanism 2 and the cabin 1.
  • the traction means runs around a deflection roller 5 and one additional pulley 6 around.
  • the deflection roller 5 is located itself above the cabin 1 and is preferably on the roof of the Elevator shaft, also called shaft head, attached.
  • the additional pulley 6 is located below the cabin 1 and is preferably at the bottom of the elevator shaft, too Called Schacht ground, fastened.
  • a first section 2.1 of the traction device 2 extends from the attachment point of the traction device 2 on the roof or upper frame 4 of the cabin 1 until it is deflected around the deflection roller 5.
  • a second Section 2.2 of the traction device 2 extends over the whole Manhole length between the deflection roller 5 and the deflection of the traction device 2 around the additional deflection roller 6.
  • the second section 2.2 thus runs, in the operating state of the Elevator, in opposite directions with respect to the direction of the first section 2.1 of the traction means 2. For example when the first section 2.1 moves up, Direction A, the second section 2.2 moves inevitably in the opposite direction, i.e. in direction B.
  • a drive unit 7 is arranged on the cabin 1 and acts on the counter-moving second section 2.2 of the traction means 2.
  • the drive unit 7 thus acts from an element moving with the traction means 2, ie in this case from the cabin 1, on yourself counter-moving section 2.2 of the traction device 2. This causes a reduction, also translation into slow called. The moment of the drive unit 7 is thereby significantly reduced.
  • the orbital velocity of a Traction sheave of the drive unit 7 is higher than that absolute speed of the cabin 1.
  • the traction device 2 is, for example, by additional wraps around rollers 8 performed. Other Geometric arrangements are also possible for this purpose.
  • a brake unit 9 is also located on the cabin 1 and also acts on the opposite moving second section 2.2 of the traction means 2. This causes that the torque of the braking unit 9 is significantly reduced.
  • Counterweight 10 Since the drive unit 7 on the opposite traction mechanism 2 drives, this can not be used as a suspension for Counterweight 10 can be used.
  • the counterweight is 10 therefore via a further deflection roller 11 with a suspension element 12 separately from the traction device 2 attached to the cabin 1.
  • FIG. 2 shows a further traction device guide arrangement, which causes a 3: 1 hanging.
  • two others Deflection rollers 13 used on the cabin 1.
  • the first Section 2.1 of the traction device 2 acts with the roof / upper Frame of the cabin 1 together via the upper pulley 13. That means the roof or the upper frame of the cabin 1 is standing with the traction mechanism 2 via the upper deflection roller 13 in Connection.
  • the same elements are designated the same as in FIG. 1 and also perform the same functions. Through this Arrangement becomes a third of the driving and braking force exercised.
  • FIG. 3 shows yet another traction device guide arrangement, which causes a 4: 1 hanging. There will be more for that fixed pulleys 14 in the shaft head and shaft pit used. The same elements become the same as in Figure 1 and Figure 2 denotes and also practice the same Functions. With this arrangement, a quarter of the Driving and braking force exerted.
  • FIG. 4 shows an embodiment with a 2: 1 suspension as in Figure 1 indicated, wherein the drive unit 7 is not on the cabin 1, but on the counterweight 10.
  • the same principle applies here as in Figure 1. Therefore there is no need for a more detailed description here. Also are the same in this embodiment Traction device guides and reductions applicable in the Figures 1, 2 and 3 are shown.
  • FIG. 5 shows a further arrangement according to the invention Elevator system that causes a 2: 1 suspension, the upper one End of the traction device 2 is attached above the cabin 1 and the lower end of the traction means 2, for example on the Shaft base is attached.
  • the lower end of the traction device 2 can also be loosely attached to the bottom of the shaft or with a Spring.
  • a memory for the traction device 2 is provided be in which the traction device 2 can be collected if the The cab moves up.
  • the lower end of the traction device 2 exercises always a minimum force greater than zero down, so the traction device 2 cannot jump in the drive unit.
  • the counterweight 10 should be lighter than the empty cabin 1 his. This arrangement also halves the Drive and braking force reached.
  • Figure 6 illustrates another embodiment of the invention represents, the traction means 2 at one of its ends with the Cabin 1 and at the other of its ends on a drum 15 is attached.
  • the traction device 2 is depending on the movement of the Cabin 1, up on the drum 15 or settled.
  • the drum 15 is located on the cabin 1.
  • the counterweight 10 should be lighter than that empty cabin 1 This arrangement also results in a 2: 1 Suspension, by halving the drive and the Braking force is reached.
  • the traction means 2 can be used, for example, as a rope, toothed belt, Be flat ribbon or chain.
  • the drive unit can basically be attached anywhere become: On the roof, below the load, sideways. Decisive for the positioning can Traction mechanism and the space available.
  • the brake unit can be integrated in the drive unit and thus also arranged on the moving element his. It can also be decoupled from this but still be on the moving element.
  • the brake unit is stationary in the elevator shaft, for example on a pulley.
  • the Drive unit can be built as small as possible, for example Drive unit short, but large scope or scope small, but long drive unit.
  • requirements also apply to Brake unit.
  • the elevator installation according to the invention nevertheless an increase in stopping accuracy (less Elasticity achieved with variable cabin load).
