Definitions

  • the invention relates to an elevator, in particular an elevator for the disabled, which can be installed in private houses, with a car guided in an elevator shaft, which is connected to a carrying train guided via at least one upper deflecting roller with a first ascending and a second descending run, with a counterweight at least partially compensating for its mass is that is operatively connected to a drive via a drive train with the first and second run.
  • Elevators are known for the vertical transport of people and loads in buildings, in which a car in a shaft on one Tragyak is hanging vertically moved, the mass of the car is at least partially compensated for by a counterweight; the elevator car, which is guided in track rails in an elevator shaft, is connected to the counterweight as upper ropes via the supporting ropes. It is advantageous if the mass of the counterweight between "mass car empty” and “mass car with maximum permissible load” is selected, advantageously in the middle between them. This ensures maximum relief for all load conditions.
  • Conventional lifts are driven via a drive arranged above the elevator shaft, which acts on the support cables of the elevator car, which then form the drive train. This design requires a machine room in the area of the shaft head of the elevator shaft, usually even a machine room set on the roof.
  • a continuous train is provided as the drive train, one end of which is fixed in the head and the other end in the foot of the elevator shaft.
  • This drive train is independent of the actual carrier train, which connects the car and the counterweight. This separation of driving operation and drive means that the load of the car and counterweight are absorbed by the deflecting pulleys of the suspension cable and do not act on the drive with its drive gear.
  • the upper run of this drive train is guided via upper rollers and the lower run via lower rollers on the counterweight, these two rollers representing loose rollers which are coupled via the body of the counterweight.
  • the ends of the drive train are each deflected via fixed rollers arranged in the head and foot of the elevator shaft in such a way that the strand connecting the two fixed rollers forms the continuous train with the other two strands.
  • the drive is provided in the area of this connecting strand.
  • the weight of the car and counterweight is essentially borne by the carrier train and its deflection rollers; the drive train is free from such loads.
  • Each of the ends of the two runs of the drive train connected to the counterweight is fixed in the head or foot of the elevator shaft.
  • Both runs are connected by the third section so that the drive train forms a continuous train, which is deflected on the counterweight with loose rollers and in the area of the shaft head or shaft foot with fixed rollers.
  • the drive train is guided in the manner of a pulley system, the first and the second strand each forming an opposing pulley system, since the first strand and the second strand are each guided by a movable roller on the counterweight and in the area of the shaft head or foot with each a fixed role.
  • the path length that the first pulley releases is used up exactly by the second pulley; this enables the operation of this continuous drive train. This affects the power of the drive motor to be made available for the drive, which can be kept smaller in accordance with the pulley reduction.
  • This connecting part of the drive train is operatively connected to the drive.
  • the fixed rollers preferably the lower ones, are designed as drive rollers;
  • this connecting strand out of the shaft area as a drive loop via two fixed rollers and to guide an output wheel of the drive motor.
  • the driven wheel is turned, one strand gets exactly as much train as is released by the other.
  • the counterweight is thus raised or lowered depending on the direction of rotation of the drive; the car connected to the counterweight via the carrier train then just shifts in the opposite direction.
  • the drive train is a chain hoist, the fixed and the loose rollers and the driven wheel of the drive motor being chain wheels.
  • the drive train is formed by a double chain, the two chains being independent of one another. Since both chains are independent of each other and the drive train must be kept taut, the fixed rollers and the loose rollers must be independent sprockets, while the driven wheel is designed as a double toothed disc, in which both sprockets are inevitably moved together. At least the loose rollers must have the same number of teeth for the same module, so that the chains connected in parallel are loaded equally and fetched or released by the same distance.
  • the total mass of the "car / counterweight" system (including the weight of the pulling rope for the first run) can only be taken up by the upper idlers of the first train.
  • the upper deflection roller of the rotating second train absorbs the weight of the chain, the portion of the weight of the counterweight and reaction forces transmitted to the second run of this train via the double spring, and is largely relieved.
  • the lower deflection rollers interact with the drive directly or via a corresponding reduction gear.
  • a further pair of deflection rollers is provided in the region of the lower deflection roller in such a way that the connecting strand part of the drive train is led out to a drive motor arranged laterally next to the elevator shaft, forming a loop.
  • a lower cable connecting the car and the counterweight is superfluous with this elevator and the drive can be arranged next to the elevator shaft, advantageously in the area of the lower end of the elevator shaft, which means additional, statically unfavorable machine rooms in the area of the roof or even on this can become superfluous.
  • the introduction of force into the system "Counterweight / car" is such that jerk-free start-up and braking is permitted, which is particularly important when transporting disabled people.
  • the load-bearing train does not require any additional tension, as the upper rope it is always tensioned.
  • the drive train can be tensioned over the upper or lower deflection roller, so that this drive train transfers the drive force to the "car / counterweight" system without dead play being able to take effect.
  • the fixed points can also be provided with tensioning means, for example with spring balancers.
  • a tensioning lever device can also be provided in the area of the elevator shaft foot, in which the drive train is held tensioned by means of weighted tensioning levers. It goes without saying that a combination of spring balancer and tension lever lever can also be used. Another possibility of tensioning the second train lies in the area of the drive or the drive motor itself. If a multiple train is provided as the drive train, each individual partial train is expediently kept tensioned with separate tensioning means; a different length of the individual partial trains is thus counteracted.
  • Figures 1 and 2 show a partially sectioned elevator shaft 1 in front view and in side view.
  • the elevator car 2 In the elevator shaft 1 with its upper end - the head 1.1 of the elevator shaft 1- and its lower end - the foot 1.2 of the elevator shaft 1, the elevator car 2 is vertically movable suspended from a carrier train 3, at the other end of which a counterweight 6 carries. The movement is transmitted from the counterweight 6 to the car 2 via the carrier train 3.
  • This carrier train 3, with one end attached to the car 2 and the other end attached to the counterweight 6, is and is guided with its ascending strand 3.1 attached to the elevator car 2 and its descending strand 3.2 attached to the counterweight 6 via fixed deflection rollers 4 and 5 redirected accordingly.
  • the counterweight 6 is connected to the drive train 9.
  • the upper deflection roller 7 is provided at its upper end with a roller holder 7.1 fastened to the counterweight and the lower deflection roller 8 is provided at its lower end with a further roller holder 8.1.
  • the upper deflection roller 7 is operated by the upper run 9.1 and the lower roll 8 by the lower run 9.2 of the drive train 9, these runs 9.1 and 9.2 being fixed at one end in the upper fixed point 10 and in the lower fixed point 13, respectively.
  • a spring balancer 10.1 or 13.1 (FIG. 1) is provided, which keeps the drive train or its individual partial trains tensioned, with individual, independent clamping means advantageously being provided for each of the partial trains.
  • FIG. 1 a spring balancer 10.1 or 13.1
  • a lever cable 18 is provided for tensioning the lower part 9.2 of the drive cable 9 instead of the spring cable at the lower fixed point 13.
  • a lever 18.3 is hinged to a U-shaped lever holder 18.1 with a bolt 18.2, the free end of which is loaded with a weight 18.4.
  • a turnbuckle 18.5 connects the lever 18.3 to the lower run 9.2 of the drive train 9 to be tensioned and tensions it, the tensioning force being given by the mass of the weight and the selected lever ratio.
  • separate clamping levers 18 can be provided for each of the partial trains of the drive train 9.
  • each roller provided in the course of the drive train 9 is designed as a sprocket when using chains, the deflection sprockets of the deflection rollers arranged on one axis being rotatable relative to one another, except for the sprockets which interact with the drive; these are fixed against each other so that they are forced to run synchronously. This compensates for any unevenness in the individual chains, such as uneven lengths in operation.
  • the respective second ends of the drive train 9 are guided via an upper deflection roller 11 or a lower deflection roller 17 and connected to one another by a strand 9.3 guided between these two deflection rollers 12 and 17, so that a continuous drive train which is fixed at both ends and which has fixed, in Area of the head 1.1 or the foot 1.2 of the elevator shaft 1, or rollers 12 and 17, respectively, and loose rollers 7 and 8, which are arranged or firmly connected to an elevator frame, are formed in the manner of a block and tackle, the loose rollers 7 and 8, over the counterweight 6 coupled, although they also have fixed distances from one another, but can be changed with respect to the respectively assigned fixed roller, as a result of which the two pulleys are formed in opposite directions (the figure shows the roller spacings unequally, only for better clarification, as a result of which hidden strand parts are otherwise hidden) are recognizable).
  • the drive can be provided in the area of this connecting strand 9.3; in the illustration, the lower deflection rollers 17 are connected to the drive motor 14 via the output shaft 16 of the output gear 15. Because of this pulley-like arrangement, the force to be exerted by the drive motor — here with a loose roller — is halved, so that the motor can be designed smaller with regard to its connected load and its power consumption even without the interposition of a reduction gear; the output gear 15, which also causes a change in direction of the axis of rotation as an angular gear, is sufficient. It goes without saying that pulley guides with two or three loose rollers are also conceivable, which result in a further reduction in force (with a longer path).
  • FIG. 3 shows a detail of an embodiment of the upper fixed point 10, at which the free end of the upper run 9.1 — shown here as a double chain — is fixed.
  • the fixed point is formed by an angle 10.1 arranged in the area of the head 1.1 of the elevator shaft 1 on its wall or on the elevator frame, through which the bolts 10.2 are guided, at the ends of which the ends of the two chain hoists of the upper strand 9.2 are fastened.
  • These bolts 19.1 can be tensioned individually by means of the nut arrangements 10.3, with lock nuts (not designated in more detail) serving for securing.
  • Figures 4 show the lower fixed point 13 with lever 18 in an enlarged view:
  • the ends of the lower run 9.2 are connected via a turnbuckle 18.5 to a weight train 18 which, by means of the lever 18.3, is designed in the form of a fork on a lever holder 18.1 provided at the lower fixed point 13 and attached to the bottom of the foot 1.2 of the elevator shaft 1, is pivotally articulated about the axle pin 18.2;
  • the lever cable 18 is shown in Fig. 4a in front and in Fig. 4b in side view.
  • a weight 18.4 acts on the lever 18.3 and generates a torque acting around the axis of the axle pin 18.2.
  • This torque translated in the ratio of the arms of this one-armed lever, acts via the turnbuckles 18.5 on the ends of the lower runs 9.2 and keeps them taut; it goes without saying that in addition to the weight or instead of the weight, a spring tension can also act on the lever, it also goes without saying that a double-armed lever can also be used instead of a single-armed lever 18.3.
