The invention discloses anti-seismic sound insulation and noise reduction equipment for an elevator. The equipment structurally comprises a main machine, a lifting mechanism, a guide rail, a counterweight device, a buffer, a well ladder and a car, wherein the lifting mechanism is provided with fixed rods, movable rods, guide shoes, a car body, a buffer plate and compression rods. According to theequipment, force is transmitted to rubber shafts through stressed plates for buffering and damping again, sound transmission generated by vibration force is reduced, friction and vibration generated when the car stops sliding are prevented from being connected with a wall to form a sound bridge, hydraulic rods fix the stressed plates to enable the stressed plates to be stressed in balance, and meanwhile inertia force generated when the car stops is buffered by the compression rods and acts on the upper end of the buffer plate, so that noise is reduced while the car stops stably; and the noisegenerated by the vibration force is weakened in friction mechanisms, sponge rings attached into fixed plates are stressed to move, generated vibration is blocked in vibration openings which open rightwards and become smaller and smaller, the noise is prevented from being increased, sound transmission in the air is reduced, and the noise is lowered.
本发明公开了一种电梯用抗震隔音降噪设备,其结构包括主机、升降机构、导轨、对重器、缓冲器、井梯、轿箱,升降机构设有固定杆、移动杆、导靴、轿体、缓冲板、压缩杆,通过受力板传递至橡胶轴再次进行缓冲减震,减小振动力产生的声音传递,防止轿箱滑行停止时的磨擦及振动与墙体连成“声桥”,且液压杆对受力板进行固定,使受力板受力平衡,同时轿箱停止的惯性力被压缩杆缓冲,作用于缓冲板上端,使得轿箱平稳停止的同时减小噪音的产生,振动力产生的噪音在摩擦机构内部进行减弱,贴合在固定板内部的海绵环受力活动,产生的振动在向右的开口越来越小的振动口中进行阻,避免噪音进行扩大,减小空气中声音的传递,降低噪音的产生。
