Description

TECHNICAL FIELD

[0001] The utility model belongs to ultrasonic flaw detection vehicle technical field, concretely relates to a subway large -scale rail ultrasonic flaw detection vehicle. BACKGROUND

[0002] The subway large -scale rail ultrasonic flaw detection vehicle is a special vehicle for subway rail detection, which adopts advanced ultrasonic flaw detection technology and can accurately detect the internal cracks, defects and other safety hazards of subway rails.

[0003] The basic principle of the ultrasonic flaw detection vehicle is to use the reflection echo of multiple groups of ultrasonic waves of different angles incident on the rail to detect whether there is damage inside the rail. The ultrasonic flaw detection vehicle emits ultrasonic waves, and when the ultrasonic waves encounter cracks, defects and other abnormal conditions inside the rail, reflection, refraction and scattering occur. The receiving device of the flaw detection vehicle receives these reflected waves and converts them into electrical signals, which are then processed and analyzed by a computer system to determine the damage inside the rail.

[0004] When the flaw detection vehicle carries out flaw detection on the subway large -scale rail in the open track area, direct sunlight will bring many problems to the detection work. Strong light forms reflection on the surface of the data display screen, producing dazzling light spots, which seriously reflects the screen display content. At the same time, strong light also reduces the contrast of the display screen itself, making the text and image information unclear, greatly interfering with the line of sight of the detection personnel. In this case, the detection personnel cannot read the detection data of the subway large -scale rail from the data display screen in time and accurately. The fine damage information such as cracks and sand holes that may exist inside the rail cannot be analyzed and judged in time. UTILITY MODEL CONTENTS
