Hydraulic tight type ultrasonic guided wave damage detecting device for stranded wire structure

Abstract

The invention discloses a hydraulic tight type ultrasonic guided wave damage detecting device for a stranded wire structure. The hydraulic tight type ultrasonic guided wave damage detecting device ischaracterized by comprising an annular base module, a hydraulic tight module, an ultrasonic probe module, a micro laser radar module and a film pressure sensor, wherein the annular base module is of an annular structure formed by a first annular base and a second annular base, the film pressure sensor is arranged at the connection position between the first annular base and the second annular base, the inside of the annular structure is a hollow structure and is filled with hydraulic oil, a one-way valve and the micro laser radar module are arranged outside the annular structure, the hydraulictight module is arranged in the annular structure, and the hydraulic tight module is connected with the ultrasonic probe module. The hydraulic tight type ultrasonic guided wave damage detecting device disclosed by the invention can quickly detect cylindrical detected parts of metal stranded wires and the like, and the detecting efficiency is remarkably improved.

Description

Technical field [0001] The invention relates to the technical field of non-destructive testing, in particular to a hydraulic tight ultrasonic guided wave damage detection device facing a stranded wire structure. Background technique [0002] Metal stranded wire is a slender structure formed by spirally twisting one or more layers of single wires around a center line. It has the advantages of high strength, superior electrical performance, and strong carrying capacity. It is often used as an effective load-bearing component and is widely used in bridges. In large-scale environments such as ports, railways, and buildings, the health monitoring of stranded structures has become a research hotspot at home and abroad. [0003] At present, researches on defect detection for stranded wire structures have been carried out at home and abroad, and non-destructive testing techniques are mainly used to detect the internal and external structure and mechanical strength of stranded wires.

AI Technical Summary

Problems solved by technology

[0004] When performing structural damage ultrasonic guided wave detection on non-ferromagnetic material stranded wires, adhesives are generally used to bond PZT piezoelectric ceramics to the surface of the stranded wires. Since the adhesive needs a certain amount of time to harden, this method is used for a large number of detection targets. In-service detection of metal strands is very inefficient
