Abstract

The invention discloses an advanced turbine blade supporting device. The advanced turbine blade supporting device comprises a rotation wheel and a main shaft extending left and right on the rotation wheel. Cone grooves with leftward openings are distributed in the left end face in the rotation wheel in the circumferential direction and penetrate through the outer surface of the circumference of the rotation wheel. Annular grooves penetrating through the cone grooves are formed in the rotation wheel. The rotation wheel is internally provided with first cavities, wherein the first cavities are located in the cone grooves and are close to the center end of the rotation wheel. A second cavity is formed in the right ends of the first cavities. A cone head is embedded in each cone groove and internally provided with a third cavity. A first guiding sliding groove is formed in the left end of each third cavity. Symmetric second guiding sliding grooves are formed in the front inner wall and therear inner wall of each third cavity in a communication manner. Third guiding sliding grooves penetrating through the second guiding sliding grooves are formed in the front inner wall and the rear inner wall of each third cavity in a communication manner. Each third cavity is internally connected with a radial-extending first rotation shaft in a rotation fit manner.
