Abstract

The invention discloses a manual ultrasonic flaw detection scanning device for defect detection of train wheels, which comprises components such as a scanning arm, a carrier mounting frame, a probe fixture, and a scanning auxiliary positioning mechanism. The scanning arm adopts a retractable mechanical structure, its length can be adjusted, and it has an automatic locking function. The carrier mounting frames are respectively installed at both ends of the scanning arm, and the probe fixtures are respectively mounted on the carrier mounting frames The fixture is installed on the crossbeam, which can be moved and fixed on the fixture installation beam according to the detection needs. The scanning auxiliary positioning mechanism is installed on the inner side of the carrier mounting frame and rolls along the top of the rim during the detection process, which can scan stably device. The present invention can be used in the ultrasonic detection mode of sending and receiving and spontaneous receiving at the same time, and has the advantages of convenient manual operation, adjustable probe distance, fixed relative position, stable detection effect and the like.

Description

technical field

[0001] The invention relates to the field of train wheel detection, specifically a manual ultrasonic flaw detection and scanning device for defect detection of train wheels. Background technique

[0002] The detection of train wheel defects is divided into two types: automatic detection and manual detection. Automatic detection generally uses mechanical auxiliary equipment to automatically realize the relative movement between the workpiece and the probe, and is equipped with a multi-channel ultrasonic flaw detector to achieve high-speed and rapid detection. Defects detected by automatic flaw detection often require manual scanning to assist detection to determine the equivalent size and position of the defect. Therefore, manual detection still plays an important role in the detection of train wheel defects.

[0003] The traditional manual ultrasonic detection of train wheel defects uses a single probe and adopts a self-generating and self-receiving detection...
