Problems solved by technology

Because the existing elevator control of the elevator installation cannot evaluate the information provided for this purpose by the monitoring unit or even communicate the status information of the monitoring unit (such as the operating state of the elevator installation, the speed or position of the car)

Embodiment Construction

[0029] figure 1 An elevator installation 10 is shown. The elevator installation has a car 1 , a counterweight 2 , a support and drive mechanism 3 on which the car 1 and counterweight 3 are suspended in a ratio of 2:1, and also has a drive wheel 5.1. Drive wheel 5.1 with in figure 1 A drive unit, not shown for reasons of clarity, is coupled and remains in operative or effective contact with the support and drive mechanism 3 .

[0030]The car 1 and the counterweight 2 can be moved substantially along vertically oriented guide rails by means of the rotational movement of the drive wheels 5.1 which transmit the drive torque of the drive unit to the carrier and drive mechanism 3 . For overview reasons, in figure 1 The rails are not shown. The car 1 and the counterweight 2 are guided on guide rails by means of guide elements such as guide shoes or guide rollers.

[0031] Here, the counterweight 2 is suspended on first cables of the support and drive mechanism 3 . The first cab...

Abstract

The lift system has a sensor (8) for detecting the vibrations that are generated in the operation of the lift system. An evaluation circuit (9) is connected with the sensor for evaluating the vibrations detected by the sensor. The detected vibrations are compared with a predetermined operating value and a predetermined threshold value by the evaluation circuit. A quality value is calculated from the comparison of the vibrations with the operating value and with the threshold value by the evaluation circuit. An independent claim is included for a method for operating a lift system.

Description

technical field [0001] The invention relates to an elevator installation having a sensor for detecting vibrations and a method for operating such an elevator installation according to the subject matter of the claims. Background technique [0002] Elevator installations have movable mechanical parts such as drives, car doors and shaft doors, car door drives, car door closing mechanisms, guide rollers or guide shoes, and their correct and problem-free functioning should be ensured. For this reason, the individual components are maintained and serviced at regular intervals. The expenditure for such maintenance work is relatively inefficient, since the maintenance intervals are fixedly preset and are not adapted to the actual wear conditions of the specific elevator installation and its components. [0003] A reliable indicator of the degree of wear of movable mechanical parts is the degree of vibration. In normal reliable operation, the vibration does not exceed a certain le...
