Description
Technical field
The present invention relates to a kind of equipment of detection architecture inside concrete defective, particularly a kind of calibrating frame of Ultrasound Instrument.
Background technology
At present, the detection of structural concrete inherent vice, using is ultrasonic pulse method the most widely.Ultrasonic method is by the speed of utilizing sound pulse to propagate in the concrete of technical conditions identical (concrete raw material, match ratio, the length of time and measuring distance are consistent), the relative variation of the parameters,acoustics such as amplitude and frequency that receives ripple, judges concrete inherent vice.The process need of calibrating Ultrasound Instrument changes the measuring distance between transducer successively, to obtain precise information.Under prior art, the verification test distance directly draws with straight steel ruler or tape measure, and the method efficient of this verification test distance is low, error is large, so that the final degree of accuracy that detects data of impact.
Summary of the invention
The object of the invention is to solve under prior art the Ultrasound Instrument verification test apart from the time efficient low, problem that error is large, and provide a kind of calibrating frame of Ultrasound Instrument easy to operate, simple in structure.
The present invention is achieved by the following technical programs:
A kind of sound velocity method prover calibrating frame, it is characterized in that comprising a scale of fixing by bracing frame is set, scale one end is provided with fixed bar, fixed bar top is provided with the first transducer, and scale one end also is provided with carriage release lever, and carriage release lever top is provided with the second transducer, carriage release lever and scale are slidably matched, scale is provided with keeper, and keeper forms the location with carriage release lever and coordinates, and also is provided with thermometer on scale.
Described keeper comprises rocking bar, and one section of rocking bar is fixed on scale by bearing seat, and another section of rocking bar is threaded connection with carriage release lever.
Described the first transducer must be coaxial with the radiating surface axis of the second transducer.
Described the first transducer and the second transducer can be the plane sound wave transducer, are the commercially available existing product in market, and one of them is transmitting terminal plane sound wave transducer, another is receiving terminal plane sound wave transducer.
Beneficial effect of the present invention is simple in structure, easy to operate, when improving calibrating efficient, has reduced measuring error, has guaranteed the accuracy and reliability that detects.
Following constipation closes drawings and Examples, and the present invention is further described:
