The main link 20 and the fixed block mount 40 can be easily connected by forming the fixed block mount 40 in a similar structure to the main link 20. As a result, When the operator manually or automatically moves the drive unit 10 in a state where the installed fixed block installation port 40 and the main link 20 are connected to each other, the main link 20 connected to the drive unit 10 and the fixed block installation As the sphere 40 is transferred along the outer circumferential surface of the turbine rotor wheel 2, the ultrasonic inspection apparatus installed on the upper surface of the fixed block installation tool 40 is positioned at an appropriate position on the turbine rotor wheel 2, The ultrasonic inspection can be continuously carried out while easily moving along the outer peripheral surface of the turbine rotor wheel 2 without changing the installation position of the turbine rotor wheel 2.

Then, the load of the driving unit 10 and the ultrasonic testing apparatus are moved to one side, so that the load is applied on the link mechanism, and the main block 20 is connected to the fixed block mount 40 provided with the ultrasonic inspection apparatus When the link mechanism of the present invention is installed on the turbine rotor wheel 2, the ultrasonic inspection apparatus is disposed so as to be positioned substantially on the opposite side of the drive unit 10.

Even when the fixed block mounting means 40 equipped with the ultrasonic inspection apparatus is installed on the opposite side of the drive unit 10 as described above, when the link mechanism is installed on the outer circumferential surface of the turbine rotor wheel 2, It may be difficult to install the link mechanism on the outer circumferential surface of the turbine rotor wheel 2 due to the uneven load due to the position of the link 20 and the fixed block installation port 40. Accordingly, A fixed block installation port 40 having the same structure as the fixed block installation port 40 is connected to an appropriate position between the link 20 and a balance weight is installed on the upper surface of the fixed block installation port 40 So that the link mechanism can be easily installed on the outer circumferential surface of the turbine rotor wheel 2.

7 (a), (b) and (c), the distance between the driving unit 10 and the rear end of the main link 20 is appropriately adjusted by using the link fixture 30, the first, second, and third gap adjusting links 50A, 50B, and 50C having different lengths are properly inserted between and connected to the plurality of main links 20 as shown in FIGS. And the rear end of the main link 20 may be further adjusted. In this case, the first spacing adjustment link 50A is formed in a arc shape and is used to connect a shorter interval than the main link 20, The three spacing adjusting links 50B and 50C are formed with a plurality of engaging holes 51B 'and 51C', respectively, while the conveying wheels 52 are provided at both ends thereof to change the installation direction of the main link 20, Can be used.
