Definitions
- the invention relates to an elevator installation with at least one elevator car, which can be driven by a traction sheave by means of a traction mechanism, wherein a tensioning means clamped by a tensioning means under tension for the elevator car is provided next to the traction means.
- the invention relates to the field of elevator installations in which the occurrence of slippage of the traction means on the traction sheave is prevented.
- the invention also relates to a method for operating such a lift installation.
- EP 0 619 263 A2 discloses an elevator installation with an elevator car, a counterweight and a traction device which connects the elevator car to the counterweight.
- the movement of a traction sheave on the traction means on the elevator car and the counterweight transmits.
- clamping means are provided, via which the elevator car is acted upon against the force of the counterweight with a clamping force.
- in high-lift elevator systems can thereby be compensated by the weight of the traction means occurring imbalance on the traction sheave, so that slippage of the traction means is prevented at the traction sheave and the stress of the traction sheave driving drive unit is reduced.
- the elevator system known from EP 0 619 263 A2 has the disadvantage that in a state in which the counterweight rests in its end position on a buffer, a further lifting of the elevator car is possible.
- the weight of the traction means acting on the traction sheave from the side of the counterweight may be sufficient to ensure the friction on the traction sheave required for lifting the elevator cage. Since this represents a significant security risk, the height of the known elevator installation is limited for safe operation.
- the object of the invention is to provide an elevator system, in which the security is improved and in particular an excessive lifting of an elevator car is prevented.
- a traction means may also have the function of supporting the elevator car.

- the measuring device has path, speed or acceleration detection means.
- a measuring device with speed detecting means or a speed detecting device is used.
- the measuring voltage output by the speed detecting device increases in absolute value with increasing vertical speed of the clamping means.
- the detection of a speed of the weight of the clamping means has the advantage that changes in position of the weight of the clamping means occurring over relatively long periods have no influence on the detection. For example, the length of the traction means and the length of the lower clamping means may increase due to the continuous load, which may lead to changes in position of the clamping means weight.
- an inoperative movement of the elevator car relative to the counterweight for example when the counterweight is stationary, has an effect in a movement of the weight of the clamping means, so that the detection of the speed of the weight of the clamping means makes it possible to detect an undesired operating state independently of the initial position of the weight of the clamping means.
- Speed detecting device comprises a magnetic rod which is at least partially magnetically formed, and at least one coil element which encloses the magnetic rod in sections and that the magnetic rod and the coil element are arranged so that a movement of the Clamping weight causes a relative movement between the magnetic rod and the coil element.
- the magnetic rod can be connected by means of a bracket or the like with the clamping means weight, so that the magnetic rod moves together with the clamping means weight.
- the coil element can be arranged in a stationary manner and be connected, for example, via a carrier to a floor or wall of an elevator shaft or other limitation of the travel area of the elevator car, such as a foundation of a truss structure.
- a control device which is connected to the speed detection device, wherein the control device stops the elevator car when a threshold value is exceeded.
- This threshold value is predetermined in relation to a maximum permissible speed of movement of the weight of the clamping means.
- the control device can actuate, for example, a safety relay for a safety chain for triggering an emergency stop.
- the threshold value can be fixed to such an extent that the speed detection device, when the elevator car or the counterweight moves up onto a buffer or when the elevator car or the counterweight locks, is able to be fixed appeals.
- the speed detection device is connected to an evaluation device and that the control device is connected by means of a bus system with the evaluation device connected to the speed detection device. Via the bus system, the detected speed of the clamping means weight or a measured variable correlated with the speed of the clamping means weight can be output to the control device. Furthermore, the control device can also access the evaluation device and, if necessary, access the speed detection device, for example to carry out a functional check.
