Description

TECHNICAL FIELD

[0001] The utility model relates to eddy current testing equipment technical field, especially a probe lifting device. BACKGROUND

[0002] Eddy current testing is a non-destructive material testing technology widely used in industrial fields, which uses alternating electromagnetic field to induce eddy current in the material to be tested, and analyzes the change of eddy current to evaluate the properties, structure and defects of the material. The effect of eddy current testing largely depends on the distance between the probe and the surface of the material. If this distance is not properly controlled, it will directly affect the strength and accuracy of the detection signal.

[0003] In traditional eddy current testing, the operator holds the probe to perform detection. The influence of environmental vibration or operation error may change the distance between the probe and the object to be detected, thereby affecting the reliability of the detection result. Some use the probe fixed in the vicinity of the production equipment to detect the material to improve the reliability of the detection result. However, for different materials and working conditions, different detection distances are often required, and the probe is difficult to adapt to the detection requirements of different materials or working conditions after being fixed.

[0047] Further, the extrusion part 204 is detachably arranged at the top end of the lever 203 by the third bolt 211, and the extrusion part 204 extends from the top end of the lever 203 to the center position of the accommodation space 105.

[0048] The extrusion part 204 is detachably fixed at the top end of the lever 203 by the third bolt 211, which is convenient to disassemble, and further facilitates the disassembly of the probe 900 when adjustment is needed. The head of the third bolt 211 can be embedded on the upper surface of the extrusion part 204.
