Definitions

  • the invention relates to an elevator with a guided on two rails with their straight end teeth facing each other and connected by means of at least one deflecting rope with a counterweight car, which with braking device, motor and gearbox for driving two, mounted on the car, with the Gearing of the rail meshing gears is equipped.
  • auxiliary devices rather use the drive device of the elevator, only a handwheel or a hand crank occurs in the cabin instead of the electric motor.
  • the invention is therefore based on the object of creating an elevator of the type mentioned at the beginning, in which an auxiliary device is provided parallel to the actual drive device of the elevator and can be operated from the outside.
  • This object is achieved in that an auxiliary device to be actuated outside the shaft and driving the deflection roller is provided, by means of which the cabin can be moved up and down by hand independently of the engine and transmission which are attached to the cabin.
  • FIGS. 3 to 5 show a manually operated auxiliary device, etc.
  • Fig. 5 shows a detail on a larger scale.
  • the elevator shaft 1 extends over three floors 2, 3, 4 and is provided at the top with a frame 5 which carries two deflection rollers 6, via which a rope 7 runs from the car 8 to the counterweight 9. This is guided in rails 9a.
  • the counterweight preferably corresponds to the full cabin weight and approximately 40% of the payload. However, it can also be expedient to make the counterweight somewhat lighter than the cabin, so that the cabin is prevented from being pulled upward by the counterweight.
  • the cabin 8 is guided on rails 10 which are designed as toothed racks and have a T-shaped cross section, into which gear wheels 11 engage, which are rotatably mounted on the roof of the cabin.
  • a drive motor 12 with a flanged gear 13 and the prescribed brake 14 on the cabin.
  • This acts on the motor shaft 15, which extends on both sides of the motor and is mounted in bearings 16.
  • Via a bevel gear 17, the gears 11 are in drive connection with the motor.
  • the gearwheels 11 are provided on both sides with wheel flanges 18, so that there is reliable guidance transverse to the longitudinal axis of the shaft longitudinal axis defined by the longitudinal axes of the rack.
  • the cabin has no guides which are effective in directions which lie in the longitudinal center plane of the shaft.
  • a speed controller 20, which acts on the motor shaft 15, is also provided on the cabin.
  • this controller can also be provided in the floor of the cabin 8, and it can interact with the gear wheels 19, so that there is greater security because the cabin can be held by gear wheels 11 and 19 which are independent of one another.
  • the controller 21 of the elevator is located on the cabin roof and is fully electronic.
  • An emergency generator not shown, e.g. a battery can be provided in the building, which allows the cabin to be lowered to the nearest stop.
  • a control option provided outside the shaft can be provided here.
  • Another or further auxiliary device can be provided in the form that an emergency call button is provided in the cabin, which releases the brake and allows the cabin to be lowered into the next stop.
  • the speed controller is preferably set so that when the 1.4 times the cabin speed is reached, a brake fan blocks a brake disc seated on the motor shaft. This blockage should not be able to be removed from the cabin. Rather, the speed controller should only be operated by specialists so that the cabin in the next stop can be lowered.
  • the brake of the speed controller 20 is designed in such a way that it makes movement of the cabin impossible even if the cable breaks.
  • the elevator car can be lowered by hand or moved upwards in the event of a power grid failure.
  • a handwheel or a hand crank it is sufficient to use a handwheel or a hand crank to set the drive wheel wrapped in the elevator rope in rotation after the magnetic brake has been released by hand.
  • an auxiliary device must also be provided, by means of which the car can be raised or lowered to the nearest floor in the event of a power failure.
  • Such auxiliary devices can be operated both from the cabin and from the building. These two types of auxiliary device can be provided simultaneously.
  • the one deflecting roller 6 is formed into a conventional traction sheave for the rope 7 connecting the cabin to the counterweight and is seated on a shaft 31 which is rotatably mounted in the supporting frame 5 and in a bearing attached to the shaft wall.
  • a sprocket 32 which is wrapped in a drive chain 33, which creates a connection with a sprocket 34, which is overhung in a bearing, not shown, which is located in the wall of the shaft 1.
  • This sprocket 34 is rigidly connected to a bevel gear 35.
  • a second bevel gear 36 is axially displaceably mounted and can be brought into engagement with the bevel gear 35.
  • the other parts of the auxiliary device are shown in Fig.
  • the bevel gear 36 is seated on a shaft 37 which is provided with a collar 38 and is displaceably and rotatably mounted in the plates 39, 40. Between the shield 39 and the collar 38, a compression spring 41 is provided, which holds the shaft 37 and the bevel gear 36 in the position shown in the relaxed state.
  • the end shield 40 is located in a wall recess 42 which is closed by a cover 43.
  • the end of the shaft 37 located in the wall recess 42 is provided with a polygon 44, onto which a handwheel 45 shown in dash-dotted lines can be attached.
  • the hub 46 of this handwheel 45 is provided with a collar 47 which interacts with the button of a switch 48 in the wall recess 42.
  • Fig. 3 the device on the top floor is shown.
  • the chain drive 33 can, however, be extended so that the device shown in FIG. 5 can be arranged on a lower floor.
  • auxiliary device If the auxiliary device is to be arranged in the cabin, its design largely corresponds to the known auxiliary device in elevator machine rooms. The only difference is that this auxiliary device does not act on a drive wheel for the rope, but on the gear wheels 11. Both auxiliary devices can be provided at the same time.
  • auxiliary device described is only illustrated in a basic embodiment.
  • cardan shafts can be provided instead of a chain transmission and a hand crank can also be used instead of the handwheel. It is essential that the brake can only be released if there is an effective drive connection between the actuating member 45 and the elevator rope 7. If this is interrupted, the magnetic brake must also apply and secure the position of the cabin.

La cabine (8) est équipée de deux roues dentées (11) s'engrenant dans la denture des rails (10), d'un dispositif de freinage (14) et d'un moteur (12) pour l'actionnement des roues dentées. La cabine (8) est guidée par les rails (10), présentant de préférence une section en T transversalement au plan médian du puits défini par les axes longitudinaux des rails, au moyen de guides (18) placés sur elle, et dans ce plan exclusivement par les dentures bilatérales. Il est prévu un dispositif de secours permettant de déplacer manuellement la cabine vers le haut ou vers le bas. Moteur (12), engrenages (13), freins (14) et le cas échéant régulateur (20) sont groupés pour la commande et le réglage et, de préférence, placés sur le toit de la cabine.
