Definitions

  • the invention relates to an elevator installation with an elevator car and at least one drive unit and a counterweight with counterweight, wherein the elevator car and the counterweight are connected to each other by means of at least one support means, and the at least one support means is deflected by at least one rotating disc or roller.
  • the drive regardless of the type of drive, either arranged in a separate machine room or it is a so-called machine room elevator in which the drive is immovable in the shaft, arranged on the elevator car or counterweight, such as from the US-A-6138799 known.
  • the arrangement in the counterweight has several disadvantages, for example, that a special design of the drive is required and that the space above the drive in the counterweight can not be used for the installation of weights and the counterweight must therefore have correspondingly larger dimensions.
  • the suspension elements may be suspension cables, chains, belts or the like.
  • the rotating disk may be formed by a traction sheave, a sprocket, a pulley or the like.
  • the invention has for its object to provide an elevator system of the type mentioned, in which the material requirements for the balance weight is reduced, the dimensions are as small as possible and can be used in the freely available on the market drives.
  • the drive of such a lift system can be with or without gear z.
  • the drive can have a single-speed, pole-scarfable or a regulated drive motor.
  • the counterweight can be dimensioned correspondingly smaller.
  • the separation of the rotating disc or roller and drive has the further advantage that access to the drive for maintenance or repair is facilitated.
  • the disc or roller and the drive by a transmission element in driving connection preferably via a belt, stand. It is then e.g. also possible that the drive connection is a gear drive or a V-belt drive.
  • Such a design has the advantage of a simple connection of drive and rotating disc or roller.
  • suspension of the elevator car and the suspension of the drive unit takes place in such a way that the traveling speed of the elevator car is higher than that of the drive unit.
  • Such an embodiment may e.g. be realized that the one end of the over the counterweight and at least one stationarily mounted roller guided support means is fixed in place and the other end of the support means is attached directly to the elevator car.
  • the suspension can be realized in such an embodiment in the manner of a pulley, ie in a simple pulley the drive means or suspension is attached to the elevator car and at least one fixed roller and then guided the rotating disc or roller of the balance weight.
  • the opposite end of the drive or support means is in turn stationary, ie, for example, fixed at the upper end of the elevator shaft.
  • a simple 1: 2 pulley is realized.
  • the balance weight with the drive unit thus lays halfway back as the elevator car. A resulting advantage is that the shaft for the balance weight can be made shorter.
  • the invention relates to a generic elevator installation, in which the drive and the rotating disc or roller form part or all of the balance weight and are connected to the counterweight to a drive unit and the suspension of the elevator car and the suspension of the drive unit is such that the driving speed of Elevator car is higher than that of the drive unit.
  • This is achieved, for example, in that the at least one suspension element is guided via the drive unit and via at least one stationarily mounted roller, wherein one end of the suspension element is stationary and the other end of the suspension element is fastened directly to the elevator car.
  • Such a suspension of elevator car and drive unit can also be done by pulley mechanisms.
  • the drive and the rotating disc or roller are mounted on the top of the counterweight or in another embodiment, when the drive and the rotating disc or roller are mounted on the underside of the counterweight.
  • Such an arrangement of drive and rotating disc or roller has the advantage of a particularly simple mounting on the counterweight.
  • the driven by the drive rotating disc or roller on the upper side and the drive are mounted on the underside of the counterweight or that the driven by the drive rotating disc or roller attached to the underside and the drive at the top of the counterweight are.
  • access to the drive is facilitated due to the separation to the rotating disc or roller.
  • the drive of the counterweight engages via a drive element on a rail arranged fixed in space.
  • a drive element on a rail arranged fixed in space.
  • Such an arrangement can, for example, be realized in that the drive between the drive element and rail via a friction wheel or in another embodiment in that the drive between the drive element and rail via pinion and rack is done.
  • the drive is then no longer on the rotating disc or roller as in some of the upper embodiments, but directly over the elevator shaft in which, for example, a friction wheel of the drive acts on a stationary rail and the counterweight moves up and down, which also the elevator car participates in the opposite upward and downward movement.
  • a friction wheel drive can be realized, for example, in that two wheels clamp a rail in the middle and by opposite rotation of the wheels, the movement takes place along the rail.
  • the pinions engage the rack and thereby move the counterweight up or down.
  • Both drive mechanisms may be known in the art, i. Other drive mechanisms are possible.
  • the at least one support means is a rope.
  • a suspension element is particularly easy to maintain and assemble.
  • Such a rope can be designed in a manner known per se, for example as a steel cable.
  • FIG. 1 shows an embodiment of the elevator installation 10 with an elevator car 12, which is connected by means of suspension 14 to a drive unit 16.

  • the first end 24 and the second end 26 of the support means 14 are stationary, i. fixed to the building, for example, fixed to the ceiling of the elevator shaft 34.
  • the support means 14 are also deflected in a conventional manner to a rotating disc or roller 20, the 22b z. B. formed by one or more belts, is connected to a drive 22.
  • the drive 22 is mounted on the bottom and the rotating disc 20 on the top of the counterweight 17.
  • the drive unit 16 which also represents the balancing weight at the same time, is composed of the counterweight 17, the drive 22 of the rotating disc or roller 20 and, in this embodiment, the transmission element 22b, for example a belt which transfers the energy from the drive 22 to the rotating one Disc or roller 20 transmits.
  • Fig. 2 shows an embodiment of the elevator installation 10 with an elevator car 12; which is connected by means of suspension 14 with a drive unit 16.
  • the suspension means 14, e.g. formed by cables are deflected about one or more stationary rollers 18 and also about one or more rollers 28, which are provided on the elevator car 12.
