Background technology
The important measure that nondestructive inspection detection is to ensure that locomotive safety running is carried out to rail using ultrasonic wave.Chinese patent
A kind of wheel seach unit for hand propelled supersonic detecting vehicle disclosed in CN20181765Y, including ultrasonic transducer, support,
Couplant, colyliform couplant container and fixed to the support shaft on car body, described support has middle for plane, plane
The first inclined plane and the second inclined plane that both sides are sequentially connected respectively, installation ultrasonic transducer is vertically offered on its end face
The circle or square window of screw and transmission ultrasonic wave, ultrasonic wave caused by the ultrasonic transducer installed in support mid-plane
Refraction angle of the beam in rail is 0 degree (refraction angle is the angle of the wave beam and vertical direction reflected in rail), and it is in steel
Wave beam vertically downward is produced in rail, mainly for detection of the horizontal crackle of rail；The first of support mid-plane both sides tilts
Refraction angle of the ultrasonic beam in rail caused by the ultrasonic transducer of relative tilt installation is distinguished on the end face in face is 37
~45 degree, mainly for detection of the waist of rail；Relative tilt is installed on the end face of second inclined plane of adjacent first inclined plane
Ultrasonic transducer caused by refraction angle of the ultrasonic beam in rail be 65~75 degree, mainly for detection of the head of rail
Portion.Because ultrasonic beam caused by three pairs of ultrasonic transducers of relative tilt installation on the end face of the inclined plane of support second is in steel
Refraction angle in rail is identical, and the direction of propagation of ultrasonic beam and the traveling of rail caused by three pairs of ultrasonic transducers
It is parallel during direction, correspond respectively to rail it is interior, in, it is outer, and the both sides of rail's end portion are then arcs, therefore even if installation
Ultrasonic transducer on the outside of the end face of the inclined plane of support second and on inner side respectively laterally and medial movement, caused by it
Ultrasonic beam can not effectively enter the both sides of arc rail's end portion, therefore the ultrasonic transducer is in the head of detection rail
Part blind area during portion be present, be especially exactly the both sides of rail's end portion.
