Definitions
- the invention relates to an elevator installation with an elevator car and at least a drive unit and a balance weight with counterweight, wherein the Elevator car and the balance weight by means of at least one support means are interconnected, and the at least one support means to at least one rotating disc or roller is deflected.
- the drive regardless of the type of drive, either arranged in a separate engine room or it is a so-called machine room-less elevator, in which the drive in the shaft immovable, is arranged on the elevator car or counterweight.
- the Counterweighting has several disadvantages, e.g. that a special one 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 that Counterweight therefore must have correspondingly larger dimensions.
- the suspension elements may be suspension cables, chains, belts or the like act.
- the rotating disk can be made of a traction sheave, a sprocket, a Pulley or the like may be formed.
- the invention has the object, a To provide elevator installation of the type mentioned, in which the material requirement for the balance weight is reduced, the dimensions are as small as possible and at the freely available on the market drives can be used.
- the at least one Drive and the rotating disk or roll a part or the whole Compensating weight and with the counterweight to a drive unit connected to and driven by the drive rotating disc or roller the top and the drive are mounted at the bottom of the counterweight or that the driven by the drive rotating disc or roller on the Bottom and the drive are mounted at the top of the counterweight.
- the drive of such a lift system can be with or without gear z.
- the drive can have a single-speed, polumschalibaren or a regulated drive motor.
- the counterweight can be correspondingly lower be dimensioned.
- the separation of rotating disc or roller and drive has the further advantage that access to the drive for maintenance or Repair is easier.
- the disc or roller and the drive by a transmission element in drive connection preferably over 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.
- the Suspension of the elevator car and the suspension of the drive unit takes place in such a way that the driving speed of the elevator car is higher than that of the drive unit.
- Such an embodiment may e.g. be realized by the one end of the guided over the counterweight and at least one stationary mounted role Supporting means is fixed in place and the other end of the suspension means directly to the Elevator car is attached.
- the suspension can in such a variant of the type Pulley to be realized, i. in a simple pulley is the Drive means or suspension means attached to the elevator car and at least one fixed roller and then the rotating disc or roller of the balance weight guided.
- the opposite end of the drive or support means is in turn stationary, i. e.g. fixed at the upper end of the elevator shaft.
- the balance weight with the drive unit So it's half way back like the elevator car. A resulting The advantage is that the shaft is dimensioned shorter for the balance weight can.
- the invention relates to a generic elevator system in which the Drive and the rotating disk or roll a part or the whole Compensating weight and with the counterweight to a drive unit be connected and the suspension of the elevator car and the suspension of the Drive unit is made such that the driving speed of the elevator car higher is as the drive unit.
- This is achieved, for example, by the fact that the at least one support means via the drive unit and at least one stationary mounted roller is guided, wherein the fixed one end of the support means and the other end of the suspension element is attached directly to the elevator car.
- Such a suspension of elevator car and drive unit can also done by pulley mechanisms. Conveniently it turned out, though the drive and the rotating disc or roller at the top of the Counterweight are appropriate or in another variant, if the drive and the rotating disc or roller at the bottom of the Counterweight are appropriate.
- 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 at the top and the drive at the bottom of the Are mounted counterweight or that the driven by the drive rotating Disc or roller at the bottom and the drive at the top of the Counterweight are appropriate.
- the drive of the Counterweight via a drive element on a spatially fixed rail attacks has e.g. the advantage that no connection of Drive to rotating disc or roller is required. Especially with a Spatial separation of drive and rotating pulley or roller is this advantageous.
- Such an arrangement can, for example, be realized by the drive between the drive element and rail via a friction wheel or in another Variant in that the drive between the drive element and rail done via pinion and rack.
- 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 a stationary rail attacks and moves the counterweight up and down, whereby the elevator car the opposite upward and downward movement participates.
- a friction wheel drive can, for example, be realized in that two Clamp a rail in the middle and by opposite rotation of the Wheels move along the rail. For a drive with rack and pinions engage the pinions in the rack and thereby move the Counterweight up or down. Both drive mechanisms can after Known prior art, i. also other drive mechanisms are possible.
- the at least one Supporting means is a rope.
- a suspension is particularly easy to maintain and Assembly.
- Such a rope can be carried out in a conventional manner, for example. as a steel cable.
