Fixing device of ultrasonic transducer for detecting quality of medium-small-sized concrete test block

Abstract

The invention discloses a fixing device of an ultrasonic transducer for detecting the quality of a medium-small-sized concrete test block. The fixing device comprises a horizontal connecting rod, two vertical connecting rods and two transducer spring clips for fixing the ultrasonic transducer, wherein the tops of the two vertical connecting rods are respectively connected to the horizontal rods, are positioned on two sides of a detected concrete test block and can horizontally move along the horizontal connecting rods; the two transducer spring clips are respectively and correspondingly connected to the lower ends of the two vertical connecting rods; a front-rear-through sliding chute is formed in each horizontal connecting rod; a through hole is formed in the upper end of each vertical connecting rod; each vertical connecting rod can be connected to the corresponding horizontal connecting rod adjustably through an outer-hexagonal adjusting screw which sequentially penetrates through each through hole and each sliding chute, and a hand-screwed adjusting nut which is in threaded connection with the end part of each outer-hexagonal adjusting screw. According to the fixing device disclosed by the invention, the structure is simple, detection error can be reduced, and the waste of human resources is avoided; the whole ultrasonic detection item can be finished by an instrument operator.

Description

technical field [0001] The invention relates to a transducer fixing device. In particular, it relates to an ultrasonic transducer fixing device for detecting the quality of small and medium-sized concrete test blocks. Background technique [0002] Concrete non-destructive testing technology mainly refers to the use of ultrasonic method to detect relevant acoustic parameter values ​​(wave velocity, amplitude and frequency) and internal defects of small and medium-sized concrete test blocks and other related quality problems. [0003] Ultrasonic testing technology for concrete quality is an important aspect in the field of non-destructive testing technology for construction projects, including using ultrasonic testing for concrete strength, ultrasonic testing for internal defects in concrete, and ultrasonic testing for concrete crack depths. In the actual production test, there are two situations that require ultrasonic testing of the concrete test block. One is that after t...

Problems solved by technology

[0005] As we all know, 2-3 people are often required to complete the ultrasonic testing process in actual engineering, of which 1 person operates the ultrasonic detector, and 1-2 people hold the radial transducer (there are 2 radial transducers); There are many vertical measuring points in the ultrasonic testing process, so the inspectors who hold the radial transducer are often fatigued, resulting in a large deviation in the vertical position of the radial transducer; in addition, ultrasonic testing requires more extensive Practical operating experience, which requires the instrument operator to practice more; but if 2-3 people are needed for each practice, it will definitely cause a large waste of human resources and bring inconvenience to others
