Fixing device for turbine blade vibration monitoring sensor

The utility model discloses a fixing device for a turbine blade vibration monitoring sensor, belongs to the field of turbines, and aims to solve the problem of lack of a tool scheme of a magnetic induction type sensor in a turbine low-pressure cylinder. According to the scheme, a stainless steel capillary tube of a wire harness protection tube is communicated with a central through hole of a discbase; a through hole is formed in the center of an upper cover of the protective sleeve; the cross section of the probe fixing frame is T-shaped, and a blind hole is formed in the center of the top end of the probe fixing frame and used for embedding the disc base; a vertical through hole is formed in the center of the probe fixing frame and communicated with the blind hole in the top end, and thediameter of the vertical through hole is smaller than that of the blind hole; a lower shell of the magnetic induction type sensor extends downwards into the protection sleeve from an upper cover of the protection sleeve, a bo
