Floating probe structure of detector in steel pipe

The utility model relates to a floating probe structure of a detector in a steel pipe. The floating probe structure comprises a probe, a pin shaft, a probe arm, a wear-resistant sheet and a floating torsion spring, one end of the probe is movably connected with one end of the probe arm through a pin shaft; the floating torsional spring is arranged between the probe and the probe arm, one end of the floating torsional spring is fixedly connected with the probe, and the other end of the floating torsional spring is fixedly connected with the probe arm; and the probe arm is fixedly connected with a wear-resistant sheet for limiting the lifting angle of the probe. The device mainly solves the problem that a probe of an existing detector is damaged at a small-magnification elbow, the probability that the probe of the detector in a pipeline is damaged at the elbow is greatly reduced, the success rate of equipment detection is improved, and the reliability and economic benefits of detector equipment operation are im
