Abstract

A high-speed elevator guide rail vibration reduction device, wherein an inner pad, a constraint plate, a single-wave pad and a wall pad are sequentially arranged on both sides of a vibration reduction plate in a box body, and the cross-sectional shapes of the vibration reduction plate and the constraint plate, and the shape of the side of the single-wave pad facing the vibration reduction plate are all sinusoidal waves, the cross-sectional shape of the inner pad is a triangular waveform, and the wall pad is a flat plate; bracket-shaped side reduction plates are also installed on both sides of the vibration reduction plate, and side pads are arranged between the side reduction plates and the inner wall of the box body. Through the shape setting of the inner pad and the side pad, different deformation moduli can be provided under different vibration conditions, thereby providing a stable, accurate and wider range of vibration reduction effects, so that the elevator has better working stability, and at the same time, the setting of the constraint plate is used to make the deformation of each elastic vibration reduction pad more balanced, so as to better utilize the vibration reduction effect of all elastic vibration reduction pads, improve the vibration reduction capacity, and make the operation of the elevator more stable, and also improve the working safety and service life of the elastic vibration reduction pads.
