High-efficiency steel pipe flaw detection device

Abstract

The invention relates to the field of steel pipe flaw detection equipment and in particular relates to a high-efficiency steel pipe flaw detection device. The high-efficiency steel pipe flaw detection device comprises a detection stander, wherein a row of conveying wheels are arranged on the detection stander; liftable guide pressing wheels are arranged on the conveying wheels; flaw detection devices are arranged in the conveying directions of the conveying wheels and comprise flaw detectors and fixed boxes which are used for holding the flaw detectors and guiding steel pipes; a collection stander is also arranged at a position close to an outlet of the detection stander; a demagnetization device is arranged at an inlet of the collection stander; a row of bearing wheels positioned in the conveying directions of the conveying wheels are also arranged on the collection stander; collection frames are arranged on any one side or two sides of the bearing wheels along the conveying directions and comprise qualified product frames close to the bearing wheels and unqualified product frames away from the bearing wheels; collection rods for collecting the steel pipes are also arranged on the collection frames or the collection stander and are positioned in clearances between the bearing wheels. The high-efficiency steel pipe flaw detection device is firm in structure and very high in efficiency.

Description

technical field [0001] The invention relates to the field of steel pipe flaw detection equipment, in particular to an efficient steel pipe flaw detection device. Background technique [0002] Before the steel pipe leaves the factory, the steel pipe production enterprise must carry out flaw detection on the steel pipe to ensure the quality of the factory steel pipe. The eddy current flaw detection method has the characteristics of continuous, fast detection speed, no need to couple with the surface of the workpiece, and high detection sensitivity. The existing quality control method of steel pipe eddy current flaw detection line runs slowly, and after the flaw detection, the steel pipe is usually unloaded manually, which has the disadvantages of low work efficiency and high labor intensity, which has become an important factor that greatly restricts the speed of steel pipe eddy current flaw detection. Factors, of course, there is also the design of the blanking mechanism, bu...

[0002] Before the steel pipe leaves the factory, the steel pipe production enterprise must conduct flaw detection on the steel pipe to ensure the quality of the steel pipe. The eddy current flaw detection method is continuous, fast, and requires no The characteristics of coupling with the surface of the workpiece and high detection sensitivity have become an important quality control method in steel pipe production. The existing steel pipe eddy current flaw detection line runs slowly, and after the flaw detection, the steel pipe is often unloaded manually, which has low work efficiency and labor intensity. The big disadvantage has become an important factor that greatly restricts the detection speed of steel pipe eddy current flaw detection. Of course, there is also a design for the blanking mechanism, but the efficiency is not very high.
