Description
Technical field
The utility model 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.The pulsed ultrasonic wave 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 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 the transducer successively, to obtain precise information.The verification test distance then directly draws with straight steel ruler or tape measure under the prior art, and the method efficient of this verification test distance is low, error is big, so that the final degree of accuracy that detects data of influence.
Summary of the invention
The purpose of this utility model be to solve under the prior art the Ultrasound Instrument verification test apart from the time efficient low, problem that error is big, and provide a kind of calibrating frame of Ultrasound Instrument easy to operate, simple in structure.
The utility model is achieved by the following technical programs:
A kind of calibrating frame of surveying air sound velocity method calibration Ultrasound Instrument, it is characterized in that comprising and arrange one by the fixing scale of bracing frame, scale one end is provided with fixed bar, fixed bar top is provided with first transducer, and scale one end also is provided with carriage release lever, and carriage release lever top is provided with second transducer, carriage release lever and scale are slidingly matched, scale is provided with keeper, and keeper forms the location with carriage release lever and cooperates, and also is provided with thermometer on the scale.
Described keeper comprises rocking bar, and one section of rocking bar is fixed on the scale by bearing seat, and another section of rocking bar and carriage release lever are by being threaded.
Described first transducer must be coaxial with the radiating surface axis of second transducer.
Described first transducer and second transducer can be the plane sound wave transducer, are the existing product that the market can be buied, and one of them is transmitting terminal plane sound wave transducer, another is receiving terminal plane sound wave transducer.
It is simple in structure, easy to operate that the beneficial effects of the utility model are, when improving calibrating efficient, reduced measuring error, guaranteed the accuracy and reliability that detects.
Following constipation closes drawings and Examples the utility model is further specified:

Embodiment
As shown in Figure 1, a kind of calibrating frame of surveying air sound velocity method calibration Ultrasound Instrument that the utility model provides, comprise a scale 8 of fixing by bracing frame 1 is set, scale one end is provided with fixed bar 6, fixed bar top is provided with first transducer 7, scale one end also is provided with carriage release lever 5, and carriage release lever top is provided with second transducer 4, and carriage release lever 5 is slidingly matched with scale 8; A rocking bar 3 is set, and one section of rocking bar is fixed on the scale 8 by bearing seat 2, and another section of rocking bar and carriage release lever 5 also are provided with thermometer 9 by being threaded on the described scale.
The course of work
When Ultrasound Instrument is examined and determine, earlier two plane sound wave transducers are separately fixed at the top of fixed bar and carriage release lever, driving carriage release lever by rotating rocker then slides at scale, thereby change two between plane sound wave transducer radiating surface distance (as 50,60,70,80,90,100mm ...), under the condition that keeps the first wave amplitude unanimity, read the corresponding sound of each spacing duration t
