APPARATUS FOR CONVEYING PROBE USED IN AUTOMATIC ULTRASONIC INSPECTION OF HORIZONTAL TUBE OF THERMAL POWER BOILER

摘要

PURPOSE: A probe conveying apparatus is provided to improve quality of a non-destruction inspection and to stably maintain power plant equipment by automatically performing an automatic ultrasonic inspection with respect to a horizontal tube. CONSTITUTION: A stepping motor(100) is installed on a supporting frame(300). A driving wheel(200) is mounted on a supporting shaft connected to the supporting frame(300). A power transmission shaft of the driving wheel(200) is coupled to a power transmission shaft of the stepping motor(100) through a power transmitting member. A probe holder is connected to ends of supporters attached to both lower ends of the supporting frame(300). First ends of the supporters are connected to an extension part, which is formed at a lower portion of the supporting frame(300), by means of an elastic member. A rotary frame(430) is attached to both ends of the supporting frame(300). A supporting roller(400) is installed on a supporting shaft connected to the rotary frame(430).
