Description

Technical Field

[0001] The utility model relates to the technical field of detection devices, in particular to a PT detection device for rough tubes. Background Technique

[0002] A rough tube is a blank tube rolled out by a tube rolling mill. After the rough tube is manufactured, it needs to be detected. Currently, the commonly used detection instrument is ultrasonic flaw detection.

[0003] In the prior art, a wall thickness detection and flaw detection device for a pressure pipeline with the publication number of CN214893181U adopts the scheme of "including a flaw detector body, a detection probe and a positioning ring. A wire is connected between the flaw detector body and the detection probe. A transmission mechanism is arranged between the positioning ring and the detection probe, and positioning mechanisms are arranged on both sides of the outer wall of the positioning ring. The positioning mechanism includes a limiting rod slidably inserted into the outer wall of the positioning ring. One end of the limiting rod corresponding to the center of the positioning ring is fixedly connected with a connecting plate, and two symmetrical concave frames are fixedly connected to the end of the connecting plate away from the limiting rod".
