Connecting device of compressor-end support of gas turbine

The utility model discloses a connecting device of a compressor-end support of a gas turbine. The connecting device is connected with an upper plate (10) of the gas turbine and the compressor-end support (70) and comprises a connecting block (20), a bushing (30), a spherical washer (40), a vertical bolt (50) and horizontal bolts (60). The connecting block is fixedly connected to the upper plate (10), a stepped hole is formed in the connecting block in the axial direction of the connecting block, a large hole is used as an adjusting portion (24), a small hole is used as a bushing portion (23), and horizontal bolt holes (26) are peripherally and uniformly formed in positions along the adjusting portion. The bushing can be embedded in the bushing portion, and the spherical washer is arranged between the bushing and the compressor-end support. A screw of the vertical bolt sequentially penetrates a connecting hole, the bushing and the spherical washer, extends into the compressor-end support and is screwed with a
