Bridge internal crack nondestructive testing equipment

The invention is applicable to the technical field of nondestructive testing, and provides bridge internal crack nondestructive testing equipment which comprises two symmetrically arranged supportingplates, the two supporting plates are connected through a connecting plate, and pulleys are mounted at the bottoms of the supporting plates; supporting stand columns are fixed to the upper surfaces ofthe two supporting plates, and a height adjusting mechanism is installed between the two supporting stand columns. The height adjusting mechanism comprises a lifting plate, and a translation detection mechanism is arranged at the bottom of the lifting plate and comprises an ultrasonic transmitting end. According to the invention, cracks and defects in a bridge can be detected; the ridge internalcrack nondestructive testing equipment can detect the condition of the bridge in real time, does not affect normal use of the bridge, can adjust the height of the ultrasonic transmitting end and the height of the bridge body in
