Definitions

  • the present invention relates to an elevator installation with a car movable in an elevator shaft, wherein a connection means is provided which has a first car-side end and a second end, wherein the first end of the connection means is fastened to a suspension provided on the car
  • the car In conventional elevator systems with a car which can be moved in an elevator shaft, the car is conveyed by means of a carrying device, e.g. B. at least one carrying cable or at least one carrying strap, which or which carrying strap is guided over a traction sheave and pulleys and is connected to a counterweight guided.
  • Car and counterweight are movable along respective guides in the elevator shaft.
  • the car is formed with guide rollers, which interact with the car guide.
  • connection means is connected to the car.
  • the connection means may be, for example, a suspension cable or a suspension rope weight compensation means.
  • Support rope weight compensation means is for example a balance chain, a bottom strap, a bottom strap or a bottom cable.
  • a suspension cable By means of a suspension cable the car is connected with e.g. supplied electrical energy.
  • data can be exchanged between the car and an external computer or control unit via the suspension cable.
  • a suspension rope weight compensation means By means of a suspension rope weight compensation means, the car with the counterweight
  • CONFIRMATION COPY connects, the changing load is compensated by the weight of the support cable with changing car position.
  • Both suspension cables and suspension rope weight compensation means as connecting means are typically attached to the underside of the car.
  • the weight of the connecting means acts on the car, which can lead to uneven loads on the guide rollers of the car.
  • the suspension cable is typically fastened on the one hand to the underside of the car and on the other hand to or in the elevator shaft.
  • the suspension rope weight compensation means is typically fastened to the underside of the car on the one hand and to the counterweight on the other hand.
  • the support rope weight compensation means may also be attached to or in the elevator shaft on the other side.
  • the connecting means acts e.g. due to the bending radius of the connecting means to be maintained mostly decentralized, so not on the central area or the center of gravity of the car. This results in an uneven force and torque distribution on the guide rollers of the car, depending on the position of the elevator car in the elevator shaft.
  • a balancing mass can be attached to the car.
  • a torque which exerts the connecting means on the guide rollers of the car can be compensated and the burden of the guide rollers can be reduced.
  • a compensation by means of balancing mass is optimal only in a certain position of the car, usually in the middle of the hoistway. In the other positions, there is still an uneven distribution of forces on the guide rollers.
  • the largest loads on the guide rollers are caused by the uneven forces and moments caused by the connecting means.
  • the entire weight of the connecting means acts on the car and thereby ultimately an undesirable force on the guide rollers.
  • a force is also present through the balancing mass, which leads to a torque and ultimately to an undesirable force on the guide rollers.
  • the elevator installation according to the invention has at least one car movable in an elevator shaft, wherein a connection means with the Car is connected and a first, car-side end of the connecting means is attached to a provided on the car suspension.
  • the second end of the connecting means is fastened, for example, in or on the elevator shaft. Alternatively, the second end of the connecting means is attached to the counterweight.
  • the elevator installation according to the invention furthermore comprises an additional cable, wherein the additional cable is fastened to the suspension in such a way that a force is exerted on the suspension, which counteracts a weight force acting on the suspension by the connection means.
  • the car is connected in particular via a suspension cable with a counterweight.
  • the carrying cable is guided in particular via at least one traction sheave and / or deflecting rollers or diverting rollers.
  • the connecting means is preferably a suspension cable.
  • the suspension cable is used in particular for supplying energy to the car.
  • the hanging cable has particular functions of a data cable. By means of the suspension cable thus in particular data are sent to the car or from the car and the car can be controlled via the hanging cable.
  • the hanging cable includes in particular several individual lines, which are combined to form the hanging cable.
  • connection means is a suspension rope weight compensation means.
  • the suspension rope weight compensation means serves to balance the masses of the suspension elements.
  • the weight force which acts on the traction sheave and / or deflection rollers or deflection rollers, changes depending on the car position.
  • the suspension means are located substantially on the car side. If the car on the other hand at the top of the shaft, then there are the Suspension means substantially on the side of the counterweight. This change causes the load on the traction sheave and the rollers to vary. Typically, this variation is compensated by a rider weight compensation means connecting the car to the counterweight.
  • the support rope weight compensation means now also changes depending on the car position between the car side and the counterweight side and compensated in this way the variation by the weight of the suspension element.
  • the invention is suitable for elevator systems with only one car as well as for elevator systems with several cars, especially several cars within a hoistway.
  • the first end of the connecting means is not fastened directly to the car but to a suspension formed thereon.
  • the suspension is at least partially decoupled from the car.
  • connection means is a suspension cable.
  • the suspension is in particular designed such that the suspension cable or the individual cables of the suspension cable are guided into the car.
  • the suspension cable or the individual cables are in the car and / or shaft side in particular with corresponding components, such as control devices connected.
  • the power supply or data transmission is ensured by means of the hanging cable.
  • a second end of the hanging cable is conventionally mounted in the hoistway, in particular on a wall or ceiling of the hoistway. It is particularly appropriate to attach the first end of the hanging cable to the wall in the middle of the vertical extent of the elevator shaft.
  • the connecting means exerts a weight force on the suspension due to its mass. This weight of the connecting means engages in the vertical direction down to the suspension.
  • a support device acts on the suspension, which exerts a force on the suspension, which is opposite to the weight of the connection means.
  • the force acting on the suspension by the support means is also referred to below as additional force.
  • the weight of the connecting means and the additional power are in particular in the balance of power.
  • a direction of the weight and the additional force are opposite to each other.
  • the amounts of the weight and the additional force are identical.
  • the carrying device is used to compensate for the weight of the connecting means.
  • the weight of the connecting means is absorbed. Any torque which a connecting means without such a support device could exert on a car is eliminated. Thus, it is prevented in particular that an uneven distribution of forces and / or torque distribution is exerted on a guide and / or guide rollers of the car. An uneven loading of the guide rollers by the connecting means is thus effectively compensated.
  • This compensation of the weight of the connecting means is optimal not only in a certain position of the car in the elevator shaft, but in every possible position of the car in the elevator shaft. This will e.g. increases the life of the guide rollers andrhythmt. Maintenance costs are reduced. Furthermore, it ensures that the car is precisely balanced in every possible position in the elevator shaft, which enhances driving characteristics and ride comfort.
  • the support means is at least partially outside or completely outside the vertical projection of the car. With this Measure the bottom of the car can be kept substantially free of means for fixing the connecting means.

  • the additional cable can be accommodated in a space-saving manner in the elevator shaft.
  • the deflection roller of the carrying device is preferably fastened in a machine room and / or in the shaft head of the elevator shaft.
  • the additional rope may also consist of several ropes or be designed in the form of a belt.
  • the suspension with respect to the car is movable, in particular vertically movable, is formed.
  • the connecting means is thus completely decoupled from the car, so that a guide, in particular guide rollers of the car, are not charged.
  • the car is in this case connected via the support cable and the traction sheave or one or more pulleys with the counterweight.
  • the counterweight connected to the connecting means. This ensures that no additional load on the guide rollers of the car acts.
  • a clamping mass is provided.
  • This clamping mass may preferably be attached to a fastener or a carriage of the suspension.
  • tensioning the additional rope is always optimally tensioned.
  • the additional cable is also tensioned (at least partially) by the connecting means or by the weight of the connecting means, this lower tension of the additional cable is less by the connecting means, the lower the position of the elevator car in the elevator shaft. If the car is in the lowermost position, a correspondingly small weight force of the connecting means acts on the additional cable. In the lowest position of the car, the additional cable is thus not or only very slightly tensioned by the connecting means.
  • the tensioning mass ensures that the additional rope is always under tension required for proper operation.
  • the additional rope is attached in a rope suspension ratio of 1: 1 to the counterweight.
  • 1: 1 to the counterweight.

This results in a large difference in the load of the additional rope through the connecting means between the highest and lowest position of the car. This difference leads in particular to an elongation of the additional rope. Carbon fibers are particularly suitable for withstanding these stresses.
