An electric double-track wheeled flaw detection vehicle

Abstract

The invention relates to an electric double-track wheel type flaw detection car. The electric double-track wheel type flaw detection car comprises a car frame, a detection device, a power supply device, a left scanning device, a right scanning device, a left driving wheel, a left driven wheel, a right driving wheel, a right driven wheel, a left coupling device and a right coupling device. The car frame comprises a car body, a left wing, a right wing, a motor assembly, a left extension coupler, a right extension coupler, a left guiding shaft, a left guiding sleeve, a right guiding shaft, a right guiding sleeve, a left guiding device and a right guiding device. The detection device, the power supply device, the motor assembly, the left guiding sleeve and the right guiding sleeve are arranged on the car body; the left driving wheel, the left scanning device, the left coupling device, the left driven wheel, the left guiding device, the right driving wheel, the right scanning device, the right coupling device, the right driven wheel and the right guiding device are arranged on the left wing and the right wing. The flaw detection car is convenient to arrange, disassemble and convey, and can be manually put away and extended, the detection accuracy is improved and the cost is low.

Description

technical field [0001] The invention relates to rail flaw detection equipment, in particular to an electric double-track wheeled flaw detection vehicle. Background technique [0002] When the train accelerates and brakes and passes through rail joints, curves and switches, it causes friction, extrusion, bending and impact on the rail. Under these repeated actions, the rail is easily damaged. At present, my country's railway transportation is busy, the line condition is poor, the rail damage rate is high, and the rails are broken due to damage, which directly endangers the driving safety. Therefore, in order to ensure the safe operation of the locomotive, the railway system needs to conduct flaw detection on the rails frequently to detect fatigue defects and welding defects in the rail head and rail waist range (including near the joint), as well as rail bottom corrosion and crescent block loss , rail head crushing and other damages, so that remedial measures can be taken in...

AI Technical Summary

Problems solved by technology

And this kind of large-scale rail ultrasonic flaw detection vehicle is a whole, very heavy, very inconvenient to carry, and the cost of carrying is quite high

[0007] In addition, the angles of the left scanning device and the right scanning device cannot be adjusted, and some damages on the rail cannot be found (such as transverse cracks at the bottom of the rail), and it is necessary to use a hand-push rail flaw detector for review, which reduces the detection efficiency

[0008] In addition, the static allowable deviation of rail lines, turnouts and curved gauges is -2~15mm. Since the above-mentioned large-scale rail ultrasonic flaw detection vehicle is integrated, the distance between the left scanning device and the right scanning device cannot be adjusted, and cannot adapt to the rail width. Flaw detection requirements for deviation changes
