DEVICE FOR MOVING A MECHANO-ACOUSTIC BLOCK DURING ULTRASONIC NON-DESTRUCTIVE TESTING OF WELDED COMPOUNDS

摘要

Usage: to detect and characterize defects in welded joints and the base metal of the main gas pipelines, as well as to determine the residual wall thickness of the main gas pipeline (MG). The essence of the utility model is that the device for moving the mechanoacoustic block during ultrasonic non-destructive testing of welded joints consists of a base made of a metal channel with two U-shaped metal plates welded to it, interconnected by a third U-shaped metal plate, through holes in two plates using a bolt-nut connection, a thrust bearing is fixed, a U-shaped mount is welded to the third plate with through a bolt-nut connection with a threaded rod with thumbscrews mounted on it, a movable metal plate with a metal corner welded to it through a loop connection is welded to the base, through the hole in which the angle of inclination is adjusted with the wing screws this U-shaped mount is welded to the movable plate on which the guide of the bypass roller is fixed through the bolt-nut connection, the angle of inclination of which is regulated by a threaded sleeve mounted on a threaded rod th fixed on the second U-shaped mount welded to the movable plate. EFFECT: provision of the possibility of moving the mechanoacoustic unit of an ultrasonic measuring apparatus over the surface of a gas pipeline in a mechanized manner. 3 ill.
