The present invention relates to a device for inspecting the cooling flow path of a gas turbine which can detect the defect of a cooling flow path efficiently as an eddy current probe can be inserted deep into the cooling flow path by enabling the eddy current probe to rotate and move forward or backward using the driving force of a driving motor. The device for inspecting the cooling flow path of a gas turbine according to an embodiment of the present invention comprises: a main body case; forward and backward moving blocks installed to be able to move forward and backward inside the main body case; an eddy current probe installed to be able to rotate forward and backward in front of the main body case and detecting the defect of the cooling flow path of a gas turbine; a guide cap installed in front of the main body case to be able to be attached and detached and guiding the eddy current probe inserted into the cooling flow path; a driving motor installed and fixed onto the forward moving block to generate a driving force and having a driving axis in the shape of a pipe; a power transmission part for rotating and moving the eddy current probe forward and backward by transmitting the driving force of the driving motor to the eddy current probe; and a drive controlling part for controlling the operation of the driving motor to be able to restrict the rotation and movement of the eddy current probe, which rotates and moves forward and backward using the driving force of the driving motor. |
