Background

The hand-push flaw detector is more flaw detection equipment used for detecting flaw of steel plates in steel mills at present, is used for carrying out full-width flaw detection on the steel plates, and comprises a flaw detection vehicle and a flaw detector arranged on the flaw detection vehicle. In the process of flaw detection of the steel plate, the edges of the steel plate are at positions with multiple internal defects (the internal defects of the steel plate are concentrated to the two sides of the steel plate in the rolling process), and the edges of the steel plate are at welding positions, so that the flaw detection requirement is high (the edges must be subjected to 100% flaw detection), but when the current hand-push type flaw detector moves linearly on the steel plate, the flaw detection vehicle is easy to deviate, and the problem of incomplete flaw detection is caused. The main reasons for the deviation include: 1. the edge of the steel plate is not trimmed and 100 percent of flaw detection of the edge cannot be really achieved. 2. Because the thickness of the steel plate is different from the plate (the thickness is different), the surface of the steel plate is uneven, and the deviation of the flaw detection vehicle can be caused. Therefore, it is desirable to provide a flaw detection vehicle and a hand-push type flaw detector capable of preventing the deviation.
