Problems solved by technology

[0017] Therefore, unnecessarily expanding the vibration frequency to be damped by the vibration damping device 12 will not only increase the size of the vibration damping device 12, but also reduce the vibration damping efficiency of the frequency band that requires vibration damping.
[0018] In addition, if the high-order harmonic vibration of the driving motor 13 generated in the vibration damping device 12 propagates to the car room 4, the passenger feeling inside the car room 4 will be deteriorated.
[0019] In addition, if foreign matter enters the moving parts such as the ball screw 14, the device will deteriorate, and it is likely to affect the smooth operation, resulting in a decrease in the vibration damping effect.

Embodiment Construction

[0103] An embodiment of the elevator vibration damping device of the present invention will be described in detail below with reference to FIGS. 1 to 6 . In addition, in the following description, the same reference numerals are often used for the same parts to omit repeated descriptions.

[0104] First, with reference to Fig. 1, the structure of the elevator to which the vibration damping device of the first embodiment is applied is briefly described. At the same time, the main cable 5 hanging down from the unshown winch is connected to the car frame 3 through the vibration insulator 6 and the car 1 is raised and lowered inside the hoistway 7.

[0105] And, the guide rollers 9 supported on the upper and lower corners of the car frame 2 by the vibration insulators (first vibration insulators) 8 are installed on the wall surface 7a of the hoistway 7 and extend in the vertical direction. Rotate on the guide rails 10L and 10R to guide the passenger car 1 to go up and down.

Abstract

A damping device of an elevator capable of improving riding comfortableness in a car by efficiently damping vibration generated in the car. A filter means is used to lower the gains of those frequency bands other than a frequency band including the lower natural frequencies of a vibration isolating means elastically supporting the car among signals obtained from a vibration measuring means installed in the car. Thus, the riding comfortableness in the car can be improved by intensively using a movable weight and a drive means for damping the vibration caused by the low natural frequencies of the vibration isolating means.

Description

technical field [0001] The present invention relates to a vibration damping device for reducing the vibration of the car room by driving a movable weight supported in the car room in a free displacement manner to move it. Vibration device improvement technology. Background technique [0002] As shown in Figure 7, the passenger car 1 of the elevator has the car room 4 supported on the car frame 2 by the vibration insulator 3, and the main cable 5 hanging down from the unshown hoist is passed by the vibration insulator 6 and the car frame 2 simultaneously. The car frame 2 is connected to the car 1 to move up and down in the hoistway 7 . [0003] In addition, the guide rollers 9 supported on the four upper and lower corners of the car frame 2 by the vibration insulator 8 rotate on the left and right pair of guide rails 10L, 10R installed on the wall surface 7a of the hoistway 7 and extend in the vertical direction to guide the car. Use car 1 to go up and down. [0004] At th...
