The invention discloses a special multi-channel ultrasonic imaging system for a steel bridge U rib. The system includes a central processing system, the central processing system is in bidirectional connection with an ultrasonic imaging processing system in a wired manner; the input end of the central processing system is electrically connected with the output end of a probe processing system in awired manner; and the input end of the probe processing system is electrically connected with the output end of an ultrasonic probe selection module in a wired mode, and the input end of the ultrasonic probe selection module is electrically connected with the output end of a U rib plate inspection unit in a wired mode. The invention relates to the steel bridge U rib detection. Position calibration of the three ultrasonic probes can be used for detecting the weld joint on the U-shaped rib plate, the imaging quality of weld joint detection is improved through a multi-channel detection mode, theimaging speed is high, the reliability of ultrasonic nondestructive detection of the weld joint is further guaranteed, and the problem that the U-shaped rib plate cannot be used due to unqualified weld joint quality is solved.
Description
technical field [0001] The invention relates to the technical field of steel bridge U-rib detection, in particular to a special multi-channel ultrasonic imaging system for steel bridge U-ribs. Background technique [0002] The steel bridge is a bridge with steel as the main construction material. It has the characteristics of high strength and high rigidity. Compared with the concrete bridge, the beam height and self-weight can be reduced. The working conditions of the steel bridge are more consistent with the assumptions in the calculation diagram. In addition, the steel bridge is generally prefabricated in the factory, spliced on the site, the construction period is short, the processing is convenient, and it is not affected by the season. However, the fire resistance and corrosion resistance of the steel bridge are poor, and frequent inspection and maintenance are required. , high maintenance costs. [0003] When inspecting the weld seam of the steel bridge U-rib, the ...
