The sound insulation elevator comprises a damping plate and a buckle plate, the buckle plate is provided with a filling cavity, the damping plate is arranged on the side close to the filling cavity and connected with the buckle plate through a connecting piece, and an asphalt layer is arranged on the outer wall of the damping plate; the filling cavity is sequentially provided with a base plate, sound-absorbing cotton and a cement plate from inside to outside, the base plate abuts against the inner wall of the filling cavity, and the cement plate abuts against the damping plate; a plurality of keels are arranged in the filling cavity at intervals, the keels vertically extend to be connected with the inner wall of the filling cavity, and the sound-absorbing cotton is divided into a plurality of blocks which are arranged between the adjacent keels; the asphalt layer arranged on the outer wall of the damping plate can effectively absorb vibration energy, and when noise is transmitted to the filling cavity through the damping plate and the cement plate, the noise is transmitted along the pipeline, so that the elastic piece can extend to drive the buffer ball to further abut against the air bag after being vibrated by the noise, and therefore the amplitude and the noise are reduced; and noise is finally isolated through the arranged sound insulation felt, and the sound insulation and noise reduction effects are good.
本发明公开了一种隔音电梯及隔音降噪装置,包括减震板和扣板,扣板具有填充腔,减震板设置在靠近填充腔一侧,并通过连接件与扣板连接,减震板外壁设置有沥青层;填充腔从内至外依次设置有垫板、吸音棉和水泥板,垫板与填充腔内壁抵紧,水泥板与减震板抵紧;填充腔内间隔设置有多个龙骨,龙骨竖向延伸与填充腔内壁连接,且吸音棉有分割为多块,设置于相邻的龙骨之间;本发明在减震板外壁设置的沥青层,可有效可吸收振动能量,当噪音通过减震板、水泥板传递至填充腔时,噪音沿管道传递,使得弹性件受到噪音震颤后可伸长带动缓冲球对气囊进一步抵紧,从而减少振幅和噪声,并通过设置的隔音毡对噪音进行最后的隔离,隔音降噪效果好。
