Steam turbine built-in fitting fixes device and method

The invention belongs to steam turbine technical field of construction.In order to solve during steam turbine built-in fitting is fixed, it is low with installation accuracy to there is a problem of that built-in fitting can not be adjusted precisely using conventional method, the invention discloses a kind of fixed device and methods of steam turbine built-in fitting.The steam turbine built-in fitting fixes device, including fixed bracket and adjustment device, built-in fitting are connect with adjustment device；Fixed bracket includes steel column and sample plate frame, and steel column is fixedly connected with sample plate frame；Sample plate frame includes crossbeam and stringer, is mutually permanently connected to form a general frame between crossbeam and stringer；Adjustment device is fixedly connected with sample plate frame, for adjusting the relative positional relationship between built-in fitting and sample plate frame.The present invention carries out the adjustment and fixation of position by using the fixed device of steam turbine built-in fitting to built-in fitting, Adjustment precision not only can be improved, and control during casting concrete to entire built-in fitting positional shift can be improved, to guarantee the installation accuracy of built-in fitting.
