AI Technical Summary

Technical Problem

Existing ultrasonic non-destructive testing equipment cannot effectively clean impurities on the outside of steel pipe concrete, resulting in inaccurate contact between the transducer and the outer wall of the steel pipe, affecting the testing accuracy. At the same time, manually drawing calibration lines is tedious and time-consuming, increasing the testing cost.

Method used

Design a device comprising a fixed frame, a self-propelled mechanism, a movable component, a transducer, an elastic cover, a collector, a cleaning component, and a material feeding component. The device cleans impurities mechanically and automatically applies coupling agent to ensure accurate bonding between the transducer and the steel-concrete composite tube.

Benefits of technology

The automated inspection process has been achieved, improving inspection accuracy, reducing labor costs, adapting to the inspection of steel pipe concrete of different diameters and heights, and ensuring the stability and accuracy of the inspection signals.

Abstract

This invention relates to the field of building construction technology, and more particularly to a non-destructive testing device for the construction quality of steel-concrete composite pipes based on ultrasound. The device includes a fixed frame, a self-propelled mechanism, a movable component, transducers, elastic covers, and collectors. The fixed frame is equipped with a self-propelled mechanism for moving the frame. The movable component is also mounted on the fixed frame. Several transducers for emitting and receiving ultrasound waves are connected to the movable component. Each transducer has an elastic cover on its detection surface for uniformly dispersing the coupling agent. Several collectors for cleaning the coupling agent adhering to the transducers are connected to the movable component. All collectors are combined into a ring shape. This invention achieves the removal of concrete blocks adhering to the outside of the steel-concrete composite pipe through a scraping part on a scraper, preventing the adhering concrete blocks from obstructing the adhesion between the transducer and the outside of the steel-concrete composite pipe, thus avoiding affecting the accuracy of subsequent testing.
