Special shock-absorbing supporting device for pipeline elbow

The invention discloses a special shock-absorbing supporting device for a pipeline elbow. The device comprises a sleeve and a vertically-arranged stand column; the sleeve is fixedly mounted on the ground and has an upward opening; one end of the stand column is fixedly connected below the elbow; a flange shock-absorbing device is arranged in the middle of the stand column; the bottom end of the stand column is inserted in the sleeve and is in clearance fit with the sleeve; and a rubber shock-absorbing pad is arranged at the bottom of the sleeve. With the special shock-absorbing supporting device for the pipeline elbow, the flange shock-absorbing device is arranged in the middle of the stand column for first-time shock absorption, shocks of the pipeline elbow above are received, aftershock fluctuations are continuously downwards transferred, repeated vertical and transverse shock absorption is realized through second-time shock absorption by the aid of clearance fitting between the stand column and the sleeve
