Abstract
The utility model provides a nondestructive testing device for an oxide layer on the inner wall of a boiler pipe, which belongs to the technical field of boiler pipe detection and comprises a connecting box, a stable mounting component and a quick replacement component, the stable mounting component comprises limiting rods arranged on two sides of one end of the inner wall of the connecting box, and screw rods are rotationally connected to two sides of the other end of the inner wall of the connecting box; the pipeline fixing device has the advantages that the two fixing rings are aligned to a pipeline and cover the pipeline, the worm rotates by rotating the rotating rings, the worm rotates to drive the turbine to rotate, the turbine rotates to drive the rotating rod to rotate, and the rotating rod rotates to drive the lead screws to rotate. A lead screw is matched with a limiting rod through external threads to enable two moving strips to be close to the middle, the moving strips move to drive a supporting device to move through a connecting plate, the supporting device moves to drive a fixing ring to clamp a pipeline, then the supporting device is rapidly installed on the pipeline, the situation that arms are ache due to manual supporting is avoided, and stable installation is achieved.
