Problems solved by technology

The fixed bed type magnetic detector is not conducive to outdoor work due to its large size
Therefore, in the wild or remote areas, portable magnetic detectors are often used. The length of the yoke chuck of portable magnetic detectors on the market is generally between 10 and 20 cm. When using a magnetic detector for flaw detection, only axial Magnetic field to detect transverse cracks, it is difficult to detect longitudinal cracks

Abstract

The invention discloses a portable magnetic detector magnet yoke clamp for a wind power stud. The portable magnetic detector magnet yoke clamp comprises a bearing inner disc, a bearing outer ring, an outer ring base, a positioning clamp base, a rubber positioning clamp, a magnet yoke positioning arm, a flaw detection clamp base and a magnetic flaw detection clamp, the bearing inner disc is located in the bearing outer ring, the two flaw detection clamp bases are fixed to the bearing inner disc, the magnet yoke positioning arms are arranged on the outer sides of the two flaw detection clamp bases, and the magnetic flaw detection clamps are arranged on the inner sides of the two flaw detection clamp bases; the bearing outer ring is fixed on the outer ring base, the positioning clamp base is fixed on the outer ring base, the rubber positioning clamp is connected to the positioning clamp base, and the clamp can detect longitudinal cracks.

Description

technical field [0001] The invention belongs to the field of non-destructive testing, and relates to a yoke clamp for a wind power stud portable magnetic detector. Background technique [0002] Bolts are one of the most important connection methods in wind turbines. If cracks occur on or near the surface of the bolts, it will cause huge hidden dangers to the safe production of power generation of the entire unit. At present, the magnetic particle detection method is mainly used for the detection of surface and near-surface cracks of wind power bolts. The equipment is mainly divided into fixed bed magnetic detectors and portable magnetic detectors. Fixed bed magnetic detectors are not conducive to outdoor operations due to their large size. Therefore, in the wild or remote areas, portable magnetic detectors are often used. The length of the yoke chuck of the portable magnetic detectors on the market is generally between 10 and 20 cm. When the magnetic detector is used for f...
