Description

Technical Field

[0002] Electromagnetic nondestructive testing is a technology that uses the principle of electromagnetic induction to detect internal defects, cracks, pores and other defects in materials. Its principle is to pass an alternating electric field through the material. When the electric field propagates inside the material, an induced current will be generated inside the material, so as to detect the internal defects of the material.

[0003] During actual use, the rail crack detection device needs to be fixed to the rail and then the transmitting coil is energized. As a result, an induced current is generated inside the rail. The probe of the rail crack detection device is fixed to the rail to detect the voltage generated by the rail, so as to detect the crack condition inside the rail.

[0004] However, in the existing rail crack detection device, since it cannot be fixed to the rail, the detection personnel need to manually adjust the distance between the transmitting coil and the rail, which greatly increases the workload of the detection personnel and is also likely to cause deviation of the detection result.
