Embodiment Construction

[0022] Typical schemes for car vibration compensation methods are shown in FIGS. 1 to 4 . Figures 6 to 8 A typical embodiment of the car vibration compensation system is shown in . In the figure, the car 5 is guided along the guide rail 7 by the guide shoe 6 . The elevator car 5 is connected to the guide shoe 6 , for example via springs / dampers 11 and a car frame 12 . Guide shoe 6 rolls on guide rail by such as roller 6 '. exist Figure 6 and Figure 8 In the illustrated embodiment, the spring / damper 11 is fixed to the floor of the car; Figure 7 In the embodiment shown, the spring / damper 11 is fixed to the roof of the car.

[0023] When using this guide shoe 6 for guidance, vibrations can be generated in the elevator car 5, especially during high-speed guidance operation. This vibration is caused by the disturbance source 8 . Such disturbance sources 8 are, for example, uneven joints on the guide rail 7 or curvatures of the guide rail 7 , which cause impacts, centrifu...

Abstract

The present invention relates to a method and system for compensating vibrations in an elevator car (5), which elevator car (5) is guided on at least one guiderail (7), vibrations being detected by at least one first sensor (1, 1') at a source of disturbance (8), vibrations being detected by at least one second sensor (2) at the affected point on the elevator car (5), the detected vibrations being interpreted by a controlling means (3), a compensating mass 4 being systematically activated by the controlling means (3), and detected vibrations being neutralized by a.compensating force of opposite sign and equal amount.

Description

technical field [0001] The present invention relates to the transport of people using an elevator car, and more particularly to a method for compensating vibrations of an elevator car, wherein at least one sensor is used for detecting vibrations of the elevator car; and a control unit , the control unit is used to interpret the detected vibration and control at least one driver to move at least one compensation block on the elevator car, thereby realizing the compensation for the detected vibration, and relates to a compensation elevator car Vibration system consisting of at least one sensor for detecting vibrations of an elevator car and a control unit for interpreting the detected vibrations and controlling at least one drive At least one compensating mass on the elevator car is moved so that the detected vibrations are compensated. Background technique [0002] Systems for transporting people generally comprise an elevator car which is guided along guide rails by guide s...
