Description

VIBRATION CONTROL SYSTEM OF ELEVATOR CAGE}

The present invention relates to a vibration control device of an elevator cage, and more particularly, after the vibration control device of an elevator cage is configured as an active vibration damping device, the elevator can monitor the status of the remote control and actively control the status through an internet network. It relates to a vibration control device of the cage.

As is well known, elevators are usually driven at high speed in a narrow and confined space, so passengers feel severe anxiety even in the case of minute vibrations, so they are always required to run in a quiet state, especially in the case of high-speed elevators, the degree of vibration or ride comfort Has become a measure of quality.

Nevertheless, most buildings in which elevators are installed are not only geometrically deformed by self-weight and vertical compressive force of the facility, but also elastically deformed by wind pressure. Installed vertically in the hoistway, the side of the elevator cage is transmitted to the guide rail that is slidably, causing anxiety and discomfort of the passengers while generating lateral vibration during the running of the elevator cage.

Accordingly, in general, the elevator is provided with a plurality of vibration damping devices for reducing vibration in each corner of the upper and lower portions of the elevator cage.
