Anti-vibration device for prevention of falling of elevator hoist

摘要

The present invention relates to a vibration damping device for absorbing vibration of a traction machine installed in a machine room above a hoistway of an elevator and preventing the elevator hoist machine from being turned off.;To achieve the above object, according to the present invention, a hoisting machine is fixed to an upper surface of one side of a pair of upper frames parallel to each other by a base, an auxiliary sheave is provided at a bottom of the other side, , A vibration plate is formed at four points between the upper and lower frames, a channel is fixed to the upper surface of the lower frame by a fastening member made of bolts, washers and nuts, a support plate is fixed to the upper part of the channel, Wherein upper and lower upper and lower plates of the vibration-proof rubber are fixed, and a hole is opened up and down at the center of the vibration-proof rubber, and the vibration-A vibration proof pipe formed of a rigid rubber material harder than rubber is inserted to be projected to each of the upper frame bottom and the support plate, and a bolt formed with upper and lower tabs And a fastening member made of nuts and lock nuts are fixed to the tabs. The lower surface of the upper frame and the bottom surface of the support plate are fixed with a rubber ring inserted and seated in the vibration-proof pipe interposed therebetween .
