Vibration isolation structure for rotating shaft balance calibration system

The invention discloses a vibration isolation structure for a rotating shaft balance calibration system, and belongs to the field of balance calibration, the vibration isolation structure comprises an independent foundation buried underground, the independent foundation comprises a plurality of piles and a pile cap, and the vibration isolation structure is characterized in that a pit with a certain depth is formed in the middle of the pile cap; the upper plane of the pile cap and the upper plane of the pit serve as installation interfaces of the rotating shaft balance calibration system, vibration isolation ditches are arranged on the periphery of the pile cap, and vibration isolation sand is filled in the vibration isolation ditches. The purpose of vibration isolation of the balance static calibration table is achieved, and original surrounding environment interference vibration can be effectively isolated; the vibration isolation structure has the advantages that the construction method is simple and easy t
