An intelligent automatic magnetic particle flaw detection device for track switch detection

Abstract

The invention relates to an intelligent automated magnetic powder flaw detection device for track turnout detection. The intelligent automated magnetic powder flaw detection device comprises a water storage tank, a drying box, a magnetic powder box, a scouring mechanism, a lifting mechanism, a drying mechanism, a recovery mechanism and two support blocks; the lifting mechanism comprises a liftingplate and two lifting assemblies, and the scouring mechanism comprises a water pipe, a rotating rod, a spraying head, a hanging rod, a first motor, a first connecting rod and a second connecting rod;and the recovery mechanism comprises a recovery assembly, a recovery box and a horizontal-moving assembly, and the recovery assembly comprises a side rod, a second motor, a rotating disc and a plurality of second electromagnets. The intelligent automated magnetic powder flaw detection device for track turnout detection makes the spraying head swing back and forth and spray out high speed water flow through the scouring mechanism, impurities, such as oil dirt and dust, adhering to a turnout are scoured, the turnout restores to be clean, the situation that distribution of magnetic powder is affected by the impurities, and consequently, the equipment detection accuracy is reduced is prevented, not only that, the magnetic powder for testing is recovered through the recovery mechanism, reutilization of the magnetic powder is facilitated, and the practicability of equipment is improved.

Description

technical field [0001] The invention relates to the field of track detection equipment, in particular to an intelligent automatic magnetic particle flaw detection device for track switch detection. Background technique [0002] The rail is the part of the superstructure of the line that directly bears various loads of the rolling stock. The rails laid on the road are prone to various damages during use under the action of locomotives and due to different maintenance and climatic conditions. Therefore, strengthening flaw detection and replacing damaged rails in time is an important measure for the comprehensive mechanical and electrical construction department to ensure driving safety. Among the various links of the rail, the turnout is a line connection device that enables the rolling stock to transfer from one track to another. Turnouts are generally made of high-manganese steel cast turnouts. Due to their special grain structure, ultrasonic waves cannot be used to detect...

AI Technical Summary

Problems solved by technology

However, in the actual inspection process, since the turnout is exposed to the outside, it is easy to absorb various dust, oil and other impurities on the turnout. These impurities are also easy to leak into the defect gaps of the turnout, affecting the magnetic particle distribution during magnetic particle inspection, resulting in inaccurate defect display. , which reduces the detection accuracy of the existing magnetic particle flaw detection device
