Locating device of energy converter used for detecting crack depth of concrete member

Abstract

The invention discloses a locating device of an energy converter used for detecting the crack depth of a concrete member, wherein scales are marked at the side surface of a base ruler by taking 50mm as the minimum unit; a longitudinal slot (6) facilitating a connecting line of the energy converter to penetrate is arranged in the middle of the bottom surface of the base ruler; a first cursor sleeve (5) and a second cursor sleeve (2) that can slide freely are sheathed on the base ruler; the first cursor sleeve (5) and the second cursor sleeve (2) are respectively provided with a first fixing knob (3) and a second fixing knob (7) that are respectively used for fixing the first cursor sleeve (5) and the second cursor sleeve (2) on the base ruler; and the bottom surfaces of the first cursor sleeve (5) and the second cursor sleeve (2) are respectively provided with a mounting hole used for installing the energy converter. With the adoption of the locating device, the fast and accurate location for the energy converter in the crack depth detection site can be realized, thereby avoiding the trouble caused by the location by adopting a common steel ruler and a marking pen originally, saving the on-site operation time, improving the observation efficiency, improving the location accuracy and reducing the measured deviation.

Description

Technical field [0001] The invention relates to a transducer positioning device for detecting the crack depth of concrete components, in particular to a single-sided flat surface that can meet the requirements of the China Engineering Construction Standardization Association "Technical Regulations for Detecting Concrete Defects by Ultrasonic Method" (CECS21: 2000) Ultrasonic plane transducer used for rapid and accurate positioning device of ultrasonic concrete crack depth detection. Background technique [0002] In many infrastructure projects such as dams and bridges, concrete components, especially mass concrete structures, often have cracks on their surfaces due to various reasons. In order to ensure the safety of the engineering structure, it is often necessary to conduct detailed investigation and measurement of these cracks to provide an objective basis for evaluation and treatment. Especially the depth of crack development directly affects the quality and safety of compon...

AI Technical Summary

Problems solved by technology

Due to the presence of coupling agent between the transducer and the concrete surface, there may be slight sliding, and the actual distance between the transducers does not match the marked distance, which will cause deviations in the measurement results

And this method of steel ruler measuring distance, marking, and then finding some observations is also cumbersome and time-consuming on-site.
