A support 18 is fixedly connected to one side, far away from the cylinder 1, of the mounting seat 2, a displacement encoder 19 is installed on the outer side of the support 18, a roller 20 is installed on an output shaft of the displacement encoder 19, and the surface of the roller 20 is in contact with the surface of the output shaft of the cylinder 1. The displacement encoder 19 is used for recording scanning displacement of the scanning device on the palm tree type blade root 21, and can produce C scanning imaging on the ultrasonic phased array detector, so that detection data can be stored and traced.
The working principle is as follows: when the palm tree type blade root ultrasonic phased array detection scanning device of the power station steam turbine is used:
in the first case, when the protrusions 211 are all detected: firstly, fixing a palm tree type blade root 21, then adjusting the tightness of a limiting bolt 7, and adjusting an included angle between two fixing seats 5, wherein the palm tree type blade root 21 is symmetrical up and down along a transverse central line A-A, so after adjustment, the two fixing seats 5 are also symmetrical up and down along the transverse central line A-A, and the outer diameter of the palm tree type blade root 21 is larger at a position closer to a blade body 22 and smaller at a position farther from the blade body 22, so that the angle between the two fixing seats 5 can be adapted to the appearance of the palm tree type blade root 21 after adjustment;
then, after the angles of the two fixing bases 5 are fixed, if some ultrasonic phased array probes 16 in all the ultrasonic phased array probes 16 are not aligned with the protrusions 211, the fixing bolt 12 can be loosened, the ultrasonic phased array probes 16 are moved, so that the probe ends of the ultrasonic phased array probes 16 are aligned with the protrusions 211, and then the fixing bolt 12 is screwed. The redundant ultrasonic phased array probe 16, which is closer to the tip part of the palm tree blade root 21, can be removed during adjustment.
And finally, the cylinder 1 is driven to move, the ultrasonic phased array probe 16 is connected with the ultrasonic phased array detector through a cable and a connector, the surface crack position of the palm tree type blade root 21 can be confirmed in a C scanning image generated on the ultrasonic phased array detector, whether the palm tree type blade root 21 is qualified or not can be directly judged, and because the output shaft of the displacement encoder 19 is provided with the roller 20, the surface of the roller 20 is in contact with the surface of the output shaft of the cylinder 1. The displacement encoder 19 is used for recording scanning displacement of the scanning device on the palm tree type blade root 21, and can produce C scanning imaging on the ultrasonic phased array detector, so that detection data can be stored and traced.
In the second case all the grooves 212 are tested: firstly, fixing a palm tree type blade root 21, then adjusting the tightness of a limiting bolt 7, and adjusting an included angle between two fixing seats 5, wherein the palm tree type blade root 21 is symmetrical up and down along a transverse central line A-A, so after adjustment, the two fixing seats 5 are also symmetrical up and down along the transverse central line A-A, and the outer diameter of the palm tree type blade root 21 is larger at a position closer to a blade body 22 and smaller at a position farther from the blade body 22, so that the angle between the two fixing seats 5 can be adapted to the appearance of the palm tree type blade root 21 after adjustment;
then, after the angles of the two fixing seats 5 are fixed, if some ultrasonic phased array probes 16 in all the ultrasonic phased array probes 16 are not aligned with the groove 212, the fixing bolt 12 can be loosened, the ultrasonic phased array probes 16 are moved, and the fixing bolt 12 is screwed after the probe end of the ultrasonic phased array probe 16 is aligned with the groove 212. The redundant ultrasonic phased array probe 16, which is closer to the tip part of the palm tree blade root 21, can be removed during adjustment.
And finally, the cylinder 1 is driven to move, the ultrasonic phased array probe 16 is connected with the ultrasonic phased array detector through a cable and a connector, the surface crack position of the palm tree type blade root 21 can be confirmed in a C scanning image generated on the ultrasonic phased array detector, whether the palm tree type blade root 21 is qualified or not can be directly judged, and because the output shaft of the displacement encoder 19 is provided with the roller 20, the surface of the roller 20 is in contact with the surface of the output shaft of the cylinder 1. The displacement encoder 19 is used for recording scanning displacement of the scanning device on the palm tree type blade root 21, and can produce C scanning imaging on the ultrasonic phased array detector, so that detection data can be stored and traced.
Third case both protrusion 211 and recess 212 are detected: since the protrusions 211 and the grooves 212 may be arranged in a random manner or alternatively in a regular manner, but compared with the two cases, it is inconvenient to remember to scan the third case, and there may be protrusions 211 and grooves 212 repeatedly scanned, so that it is generally not recommended to do so.
