The invention provides an elevator vibration and noise reduction device, and belongs to the technical field of elevators. The elevator vibration and noise reduction device comprises a lift car, a first magnetic part, a containing groove, a second magnetic part, an elastic part and a noise isolation part. According to the elevator vibration and noise reduction device, the elastic part pushes the second magnetic part to move in the direction getting close to the containing groove until the elastic part abuts against the first magnetic part, the polarity of the second magnetic part is the same asthat of the first magnetic part, the second magnetic part can stretch into the containing groove under the combined action of repulsive force and elastic force, and a gap is formed between the secondmagnetic part and the first magnetic part. Due to the fact that the second magnetic part is arranged in the containing groove of the first magnetic part, skewing of the lift car can be avoided. Friction can be reduced through the gap between the first magnetic part and the second magnetic part, and vibration and noise of the lift car are reduced. When the lift car ascends or descends, the elasticpart can be extended and contracted, noise can be produced in the extending and contracting process of the elastic part, the noise isolation part can reduce the noise produced due to extension and contraction of the elastic part, and the noise reduction effect is improved.
本发明提供一种电梯减振降噪装置,属于电梯技术领域。该电梯减振降噪装置包括轿厢、第一磁性件、容置槽、第二磁性件、弹性件和噪声阻隔件。本发明中的弹性件推动第二磁性件朝着靠近容置槽的方向运动至抵接于第一磁性件,第二磁性件的极性和第一磁性件的极性相同,在排斥力和弹力的共同作用下使得第二磁性件伸入容置槽内并与第一磁性件之间形成间隙,通过第二磁性件设置于第一磁性件的容置槽以避免轿厢发生偏移,通过第一磁性件和第二磁性件之间的间隙实现减少摩擦,降低轿厢的振动和噪音,在轿厢上升或者下行时,弹性件会发生伸缩,在弹性件发生伸缩时会产生噪声,噪声隔绝件可以降低由弹性件伸缩形成的噪声,提高降噪效果。
