Definitions

  • the invention relates to a machine house-less elevator, in which the cabin, which is connected to a counterweight by means of a connecting cable running over a deflection roller, is provided with an engine which drives at least one friction wheel interacting with a stationary component of the elevator, and wherein the cabin has at least one safety device and a control device having.
  • Such an elevator is described in DE-B-12 51 925. It has a safety gear which is actuated by means of a rope, starting from the floor of the cabin and guided around a spring-loaded deflection roller in the shaft floor and returned to the cabin via a further deflection roller on the shaft ceiling.
  • the upper pulley interacts with a centrifugal acceleration controller, which responds to the rope movement when a predetermined speed is exceeded and tries to hold the rope.
  • the end of the rope that ends at the cabin ceiling is attached to a lever, when it is pivoted, a pinion can be rotated in the area of the shaft wall. This pinion cooperates with a rack mounted on a wedge, which in turn can slide on an inclined surface of the yoke.
  • the yoke is firmly connected to the cabin.
  • the wedges are moved on the inclined surface and come into contact with the shaft wall, which intercepts the cabin.
  • the invention aims to provide an improved safety device for such friction wheel operated elevators.
  • the safety gear of the cabin consists of a brake unit that is directly connected to the drive, which responds if there is an impermissible deviation from a target speed of the cabin, and that the deflecting pulley of the connecting cable to the counterweight also has a braking unit that responds if the deviation from a target speed is inadmissible , having.
  • the invention further relates to refinements of this basic idea.
  • FIGS. 1 and 2 show a longitudinal and a cross section through an elevator shaft and FIGS. 3 and 4 sections along and across the elevator shaft in the area of the drive.
  • the elevator shaft 1 extends according to FIG. 1 over three floors 2,3,4 and is provided at the top with a scaffold 5, which carries two deflection rollers 6,6 ', via which a connecting cable 7 from the conveyor 8 designed as a car to the counterweight 9 runs. 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, which prevents the cabin from being pulled upward by the counterweight.
  • the cabin 8 is guided on rails 10 with a T-shaped cross section, which engage in guide rollers 11. These are rotatably mounted on the roof of the cabin. There is also 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.
  • the friction wheels 21 are in driving connection with the motor 12 via a bevel gear 17 each. They are seated on shafts 22 which emanate from the bevel gear 17.
  • Each friction wheel 21 is covered with an elastic material that has a high coefficient of friction. With this coating, the wheels 21 roll on a counter track 23, which is formed by a projection in the masonry 24 of the shaft 1.
  • a rough covering 25 is applied to its end face in order to increase the coefficient of friction.
  • This The covering can be made of concrete or a mortar. Rough metal strips, especially with a textured surface, can also be used. Due to the inherent elasticity of the coating of the friction wheels 21, it is not necessary to support these wheels themselves elastically.
  • the cabin is guided by means of the wheels 11 and their flanges 18 in the direction transverse to the median plane given by the rails 10.
  • the friction wheels 21 ensure that the cabin is guided parallel to this central plane.
  • a speed controller 20, which acts on the motor shaft 15, is also provided on the cabin.
  • the control 26 of the elevator is also 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 such a way 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 can be lowered to the next stop.
  • the brake of the speed controller 20 is designed so that it makes movement of the cabin impossible even in the event of a cable break.
  • 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 guide rails 10 can also be used as a counter track. Such an embodiment is shown in FIGS. 3 and 4.
  • the guide rail 10 is fastened to the wall 24 of the elevator shaft. Your web 27 engages in a cutout 28 of the canopy 8 '.
  • On this roof is the drive motor 12, which drives a friction wheel 29 via the motor shaft 15, which is mounted in a bracket 30.
  • a pressure roller 31 is provided which is rotatably mounted in a rocker arm 32. This is pivotally mounted in a bracket 33.
  • the axis 34 of the pressure roller 31 is on the one side of the rocker arm 32 in front. On this projecting part of the axis 34, a tension spring 35 is suspended, which is anchored at 36 at its other end.
  • the rocker arm 32 is only slightly inclined so that the pressure force of the pressure roller on the web 27 is a multiple of the force of the spring 35.
  • the arrangement can also be made in such a way that the rocker arm 32 is replaced by a rocker arm 37, which is shown in broken lines in FIG. 3. It is pivotally mounted on the console 30, the rocker arm 32 and the console 33 are then omitted. However, the action of the spring 35 is the same.
  • the deflection roller 6 can be connected to a braking and / or safety device.
  • the connecting cable runs in a wedge groove of the deflection roller 6, so that sliding of the cable 7 with respect to the roller 6 is avoided.
  • the guide roller 6 ' can be set lower.
  • Another method of using the full wrap angle is that the deflection rollers 6, 6 'are connected to one another by a toothed chain gear, which has the transmission ratio 1: 1.
  • a further deflection roller can be provided between the deflection rollers 6 and 6 'and above the latter (not shown), the distance from the deflection rollers 6,6' is selected such that the connecting cable 7 runs along a wavy line. This additional pulley with V-groove can also be included in the chain gear.
  • the friction wheels can be assigned washing directions which, with the aid of chemical substances, move the peripheral surface of the friction wheels or the surface of the counter track from when the conveyor is moving Clean greasy or soapy substances.
  • the coatings of the friction wheels can consist of several layers, of which the outer wear layer has a different color than the layers arranged further inside.
  • the wear of the wear layer can be estimated from the remaining thickness of the colored ring that the wear layer forms in the end view.
  • the drive and control of the cabin can of course also be attached below the conveyor on the floor, which e.g. is required if the conveyor consists of a platform or a basket.
  • the invention is not limited to the illustrated and previously described embodiments. So it is not necessary that an elevator shaft is provided. Scaffolding can also be used, as is especially the case with construction lifts. The invention is also applicable to a system in which a single supporting column is provided, on which the conveyor is guided.
  • the pressure roller 31 can be replaced by a friction wheel which is driven, for example, via a cardan shaft, so that it pivots the rocking lever 32 can participate.
  • the invention can also be used retrospectively in existing elevator systems. If a device according to FIGS. 3 and 4 is used, no structural changes in the elevator shaft are necessary, the existing machine house can be removed. The deflection rollers 6, 6 'are sufficient. The rails 10 are used as counter-tracks according to the invention for the friction wheels 29. The drive and the safety devices can be attached to the conveyor at any time. The trailing cable required in the invention for supplying the drive motor 12 with electrical current and the control cables are not shown in the drawing.
