Multi-channel probe rack for ultrasonic and automatic thick-walled pipe detection system

The utility model relates to a multi-channel probe rack for an ultrasonic and automatic thick-walled pipe detection system and belongs to the field of detection equipment. According to the multi-channel probe rack, a traveling wheel is arranged between a rail and an automatic detection vehicle; the lower part of the automatic detection vehicle is provided with a motor; the head of the motor is provided with a gear; the gear is meshed with a rack; a detection host is arranged on the automatic detection vehicle; a movable rack can vertically move below the automatic detection vehicle; and the probe rack is arranged on the movable rack. Due to the left and right supporting arms, defect scanning and position detection of the detected pipes along the radial direction are respectively realized by multiple ultrasonic probes, the defect scanning and position detection in the circumferential direction are realized through a transverse wave probe rack, and the detection efficiency is improved. When the defect of the outer wall of the pipe is detected during longitudinal wave detection by employing a probe mounting arm, a vortex probe arm is adopted. The multi-channel probe rack is suitable for detecting pipes of different diameters with the caliber of more than 59mm, and the probe rack can be automatically adjusted, so that each probe is respectively positioned at the transverse wave and longitudinal wave detection positions of different pipes.
