The invention discloses a rubber vibration reduction device for noise reduction of an elevator machine room. The rubber vibration reduction device comprises an upper supporting plate, a rubber vibration reduction pad and a lower supporting plate, all of which are sequentially arranged from top to bottom. Double-head screws are arranged on the two sides of the top of the upper supporting plate, the two double-head screws sequentially penetrate through the upper supporting plate, the rubber vibration reduction pad and the lower supporting plate from top to bottom, the bottoms of the two double-head screws are in screw joint with the lower supporting plate and are tightly welded to the lower supporting plate, and the upper portions of the two double-head screws are sequentially connected with rubber sound insulation pads and gaskets from bottom to top in a sleeved manner. In the rubber vibration reduction device, the vibration reduction device is connected with embedded iron, I-shaped steel or channel steel of the elevator machine room in a welded manner, vibration can be directly isolated through the vibration reduction pad, loads can be averagely distributed according to different stress loads, a main engine has the advantages of being stable in running, good in vibration reduction performance, resistant to aging, long in service life and the like, a split nut and split pin manner is adopted for connection, and nut falling caused by vibration and buckle moving can be avoided.

    本发明公开了一种电梯机房降噪用橡胶减震装置,包括从上往下依次设置的上支撑板、橡胶减震垫和下支撑板,所述上支撑板顶部两侧均设有双头螺杆,且两根双头螺杆从上往下依次贯穿上支撑板、橡胶减震垫和下支撑板,两根所述双头螺杆的底部与下支撑板螺接并紧密焊接,两根所述双头螺杆的上部均从下往上依次套接有橡胶隔音垫和垫片。本发明中,减震装置与电梯机房预埋铁、工字钢或槽钢采用焊接连接,直接可将震动通过减震垫隔离,可根据不同的受力载荷,能平均分配载重,使主机运行平稳,减震性能好,耐老化,寿命长等优点,采用开口螺母与开口销的方式连接,可防止因发生震动移扣引起的螺母脱落。
