Description

Technical Field

[0001] This utility model relates to the field of steel structure defect detection technology, specifically to an intelligent detection device for steel structure surface defects. Background Technology

[0002] Magnetic particle testing is generally used to detect surface defects in steel structure components. An external magnetic field is applied to magnetize the workpiece. If there are no defects on the magnetized workpiece, the magnetic properties of each part are basically the same. However, when there are defects such as cracks, pores, or non-metallic inclusions, a leakage magnetic field will be formed on the surface of the workpiece, which will attract magnetic powder to form magnetic powder accumulation at the defect site—magnetic traces. This allows us to analyze and determine whether the defect exists, its location, and its size.

[0003] Chinese Patent No. CN215727877U discloses a surface defect detection device for steel structures, including a flaw detector. A magnetic suspension fluid storage assembly and two probes are disposed below the flaw detector. The probes are located at both ends of the flaw detector, and the magnetic suspension fluid storage assembly is located between the probes and connected to the flaw detector. This provides a novel surface defect detection device, allowing for adjustment of the relative positions of the probes as needed to meet the flaw detection requirements of different locations on the steel structure. This invention solves the problem that existing magnetic particle flaw detection equipment cannot adjust its structure according to work requirements, thus affecting the flaw detection work.

[0004] The shortcomings of the above-mentioned existing technical solutions are that the device is handheld and is inconvenient when inspecting large steel plates, and there is still room for improvement in its applicability. Utility Model Content

[0030] Both sides of the mechanism threaded rod 72 are provided with parallel mechanism slide rods 73, and both ends of the mechanism slide rods 73 are fixedly connected to the mechanism mounting plate 71.

[0031] In some specific implementations, two mechanism mounting plates 71 are provided.

The movable frame 74 is threadedly connected to the threaded rod 72 of the mechanism through the threaded sleeve 75. A sliding sleeve 76 is threaded through and fixedly connected to the movable frame 74. The movable frame 74 is slidably mounted on the sliding rod 73 of the mechanism through the sliding sleeve 76.

A rotating baffle 11 is fixedly connected to the upper end of the rotating plate 10. A drive motor 9 for driving the rotating plate 10 to rotate is provided on one of the fixed side plates 8.

[0035] A bearing 2 is embedded and fixedly connected through the fixed side plate 8. The outer ring of the bearing 2 is fixedly connected to the fixed side plate 8.
