The embodiment of the invention provides a suspension structure of a damper, a tower tube buffering device, a tower tube and a wind generating set. The suspension structure of the damper comprises a first flange and a hoisting beam, the neck portion of the first flange and the tower tube wall are fixedly connected in an annular face mode, and the end, provided with a bolt hole, of the first flangeextends out towards the inner side of the tower tube. The hoisting beam is erected at the end of the first flange and fixedly connected with the end. According to the suspension structure of the damper and the tower tube buffering device, the first flange with the annular face fixed to the tower tube wall is designed to mount the hoisting beam so as to enable the suspension structure and the tower tube wall to be fixedly connected in the annular face mode, so that impacting force of the damper on the hoisting beam is not transmitted to the tower tube wall in a point distribution mode, is dispersed to the annular periphery of the tower tube wall and thus is prevented from generating single-point or multi-point impacting and tearing on the tower tube wall.
