초록 ▼

The invention is a carriage type sonic or ultrasonic testing apparatus for flaw and deterioration detection testing in a structure, especially concrete. The apparatus detects both location and type of flaw in a structure. The carriage unit incorporates a rolling pond feature which includes: i) foam-covered tracks and rollers, this soft foam material in addition to its primary function prevents vibration of the transducers while traversing rough surfaces such as weathered concrete. The tracks and rollers form a water-tight seal with each other and the specimen surface; ii) an air-removal brush assembly which maintains contact with a specimen surface to facilitate transmission and reception of ultrasonic energy into and out of a test specimen; iii) an ultrasonic isolator element and optional wave absorbers; and iv) the ultrasonic transducer suspension system. A transducer water bed is continuously maintained while the system is in motion across the concrete. A sealed space surrounds the transducer system, and that space is continuously flooded with water so as to keep the bottom sections of the transducers submerged. This sealed space continuously transports a sufficient amount of fluid (water) along the concrete surface for proper acoustic coupling. The ultrasonic transducer includes a granite wedge as an impedance-matching transducer faceplate material for concrete structural examinations.

[ We claim:] [1.] Apparatus for simultaneously transporting acoustical testing mechanisms across the surface of a solid specimen while analyzing the condition of the interior of that specimen by acoustic waves traveling within the specimen and reflecting from surface boundaries within the specimen comprising:an assembly within a frame for acoustically communicating with the specimen including at least a single pair of planar type acoustical communicating elements and an acoustic isolation device placed between the pair of elements that is in contact with the specimen surface,a fluid sealing roller-traction means including a pair of outer belts and front and back rollers for rolling on the external surface of the specimen that is attached to the frame for allowing movement in a direction of the frame over the surface of the specimen with a relatively constant spacing therefrom,a pulse encoder means for actuation of the acoustical communicating assembly that is mechanically coupled to the roller-traction means,an acoustical-transmissive fluid maintained and sealed within a base portion of the fluid sealing roller-traction means between said belts and roller and a bottom portion of the at least a single pair of planar acoustical communicating elements and the specimen surface such that said fluid is carried across the specimen, andmeans for attaching the assembly to the frame to suspend the assembly above the specimen surface as the frame is motivated over the specimen surface for establishing acoustical communication with the interior of the specimen, the attaching means including means for physical adjustment of each of the acoustical communicating elements.
