Abstract

The invention provides a blade guiding rolling device for static frequency detection of large blades. The blade guiding rolling device is capable of solving the problems of difficult frequency detection mounting of existing huge and superheavy blades and easy damage of roots of blades during frequency detection mounting. The blade guiding rolling device comprises a guiding assembly and a rolling assembly; the guiding assembly comprises two guide blocks; the two guide blocks are mounted on two side surfaces of a top opening of a wheel slot of a frequency detector, respectively, and arranged to extend in a length direction of the wheel slot; the rolling assembly extending in the length direction of the wheel slot is mounted on a bottom surface of the wheel slot of the frequency detector.

Description

technical field [0001] The invention relates to the technical field of static frequency detection tooling for blades, in particular to the technical field of tooling for static frequency detection of super-long and overweight large blades, in particular to a blade guide rolling device for static frequency detection of large blades. Background technique [0002] With the increasing power of blade generators and the demand for high-power nuclear power units, the design and manufacture of blades tends to be super-long and over-weight, while the allowable assembly clearance between the blade root and the wheel groove of the frequency measuring device is still very small No change, due to reasons such as super long blade, overweight and no lifting hole of the blade itself, it is difficult for the operator to accurately control the orientation of the blade suspended in the air by the crane, and the blade is easily hit by the wheel groove block at the moment when the blade is insert...
