Embodiment approach

[0050] Mobile platform 0:

[0051] see Figure 2A and Figure 2B , the translation track 01 of the mobile platform 0 has two guide rails 001 parallel to each other, the translation support 003 is arranged on the two guide rails 001, and one end of the guide rail 001 has a drive motor that can be controlled by the control and acquisition device 5 004, the drive motor 004 drives the translation support 003 to move linearly along the guide rail 001 through the lead screw 002.

[0052] Furthermore, the two ends of the two guide rails 001 of the translation track 01 of the mobile platform 0 are respectively pinned with a fixed block 005, and the fixed block 005 is fixed to the table top 006 of the mobile platform 0, and the translation support 003 is passed through the These two guide rails 001 and their bottom surfaces are suspended on the platform 006 of the mobile platform 0. The bottom surface of the translation support 003 also has two pulleys that can bear the gravity of th...

Abstract

The present invention relates to a magnetic memory scan detection apparatus of a cylindrical ferromagnetic component, comprising: a mobile platform; a lifting mechanism with one end fixed on the mobile platform, wherein the lifting mechanism includes a fixed portion and a lifting portion; a cross arm walking beam mechanism with one end fixed on the lifting portion, wherein the cross arm walking beam mechanism includes a fixed end and a guide rail beam, and the guide rail beam is provided with a movable block; a rotation mechanism arranged at the movable block, wherein the rotation mechanism is provided with a vertical shaft and the rotation mechanism can rotate by taking the vertical shaft as an axis; a rotation detection arm mechanism with a fixed end fixed on the rotation mechanism, wherein a rotating arm extends from the fixed end, the other end of the rotating arm is provided with a detection arm extending downwardly, and the detection arm is provided with a magneto-dependent sensor; and a control and acquisition device arranged at the fixed portion of the lifting mechanism. The magnetic memory scan detection apparatus is suitable for assembly lines, can perform early diagnosis and prediction for microscopic damage of the cylindrical ferromagnetic member, thereby preventing the generation of major failure of mechanical equipments and preventing security incidents.

Description

technical field [0001] The invention relates to a non-destructive testing device applied in the petrochemical field, in particular to a magnetic memory scanning testing device for a cylindrical ferromagnetic component. Background technique [0002] In the field of oil and gas exploration and development, there are many large-scale mechanical equipment with hydraulic systems, and most of them will be applied to cylindrical ferromagnetic castings or forgings as common components of hydraulic systems. As the service life of mechanical equipment increases, such castings or forgings will suffer early damage due to the long-term exposure to high temperature, high pressure and alternating loads, such as microcracks in the cylinder caused by stress concentration. If these early damages cannot be detected during the periodical maintenance of mechanical equipment, when the work is restarted, the re-stressing of these tiny cracks is likely to cause cracking of the cylinder, causing ser...
