The invention discloses a rubber vibration isolation device which comprises an upper support plate and a lower support plate. The upper support plate is connected with the lower support plate through a damping vibration isolation plate, a damping spring piece is arranged in the damping vibration isolation plate, the damping spring piece penetrates through the top and the bottom of the damping vibration isolation plate, the damping vibration isolation plate is connected with the upper support plate and the lower support plate, the portions, close to the two ends, of the upper support plate are each vertically provided with an air bag, the top of each air bag penetrates through the upper support plate, an air bag connecting shaft is installed at the bottom of each air bag, the bottom of each air bag connecting shaft is located on a metal rubber sleeve, the air bag connecting shafts are movably connected with the corresponding metal rubber sleeves. By means of the rubber vibration isolation device, the purposes of energy absorption and vibration isolation can be achieved, the device is pressure proof and wear proof, the vibration period of the structure can be prolonged, the acceleration response of the upper structure can be reduced, sufficient flexibility is achieved in the horizontal direction, the vibration attenuation can be achieved, the structure displacement can be limited, and the usage is safer and more reliable.
