AI Technical Summary

Technical Problem

Existing ultrasonic detection devices for pile foundation reinforcement cages are prone to jamming or shifting with the inner wall of the reinforcement cage during use, and lack an effective guiding structure, which affects the detection stability and vertical lifting.

Method used

The system employs a guide bracket and lifting mechanism, including a spring support arm and roller structure for the guide bracket, combined with a conical guide head and adjustable counterweight, to ensure that the detection unit remains vertical and stable within the steel cage. The guide ribs and electromagnetic shielding layer reduce friction and electromagnetic interference.

Benefits of technology

It enables stable movement of the detection unit within the rebar cage, reduces friction and electromagnetic interference, improves detection stability and accuracy, adapts to rebar cages of different diameters, and ensures that the detection depth meets design requirements.
