The two groups of motors 28 installed on both sides of the operating table 1 can perform a synchronous rotation mode under the same group of controllers, thereby ensuring that the two groups of screw rods 26 rotate synchronously.

[0036] Working principle: After the pipeline 15 to be tested is installed, it should be ensured that the mounting frame 19 is moved to the rightmost side of the operating table 1, and the two sets of motors 28 are driven to rotate synchronously to realize the synchronous rotation of the two sets of screw rods 26, so that the mounting frame 19 is driven to move to the left along the two sets of screw rods 26 through the two sets of threaded sleeves 25, so as to realize the movement of the three sets of fixed seats 22 on the pipeline 15 to be tested, so that the detection plate 24 installed in the fixed seat 22 can be used to perform flaw detection on the pipeline 15 to be tested. Before the fixed seat 22 moves, the nozzle 30 installed on the cleaning tank 29 can first clean the surface of the pipeline 15 to be tested.
