Automatic flaw detection device suitable for detection of rail train wheelset

Abstract

The invention discloses an automatic flaw detection device suitable for detection of a rail train wheelset. The automatic flaw detection device comprises a detection trolley, a two-level lifting platform, a top rotary wheel mechanism, manipulators, probe carriers, an electrical control mechanism and a coupling water mechanism. The automatic flaw detection device is characterized in that the detection trolley moves in a trench along a rail; the two-level lifting platform comprises a large platform body and a rotary platform body; the large platform body is fixed to the detection trolley through stand columns and can do lifting motion along the stand columns; the rotary platform body is fixed to the large platform body through guide columns, and the top rotary wheel mechanism is fixed to the rotary platform body; and the manipulators are mounted on a fixing frame on one side of the top rotary wheel mechanism, the probe carrier is mounted on each manipulator, and the electrical control mechanism and a coupling water tank are correspondingly mounted at the two ends of the detection trolley. The automatic flaw detection device has the functions of automatic positioning of the carrier, two-level lifting of the platform and rotating of the platform, and according to the rail train overhauling trench environment and the vehicle bottom space, the height of the detection platform can be adjusted flexibly, and the detection position can be selected freely.

Description

technical field [0001] The invention relates to the technical field of wheel flaw detection, in particular to an automatic flaw detection device suitable for rail train wheel set detection. Background technique [0002] At present, on-line ultrasonic flaw detection of rail train wheelsets, on the basis of manual flaw detection, automatic flaw detection equipment is gradually introduced. Manual flaw detection is affected by the skills of flaw detectors, the level of equipment operators, and the status quo of the maintenance environment. The detection efficiency is low and it is easy to misjudge and miss judgment. , there are potential safety hazards, and the automatic flaw detection equipment is limited by the difference in the type of rail trains and the space change of the maintenance trench, which will cause poor adaptability of the detection platform to the scene, collision between the carrier and the bottom parts of the vehicle, and the inability to realize the positionin...

[0002] At present, on-line ultrasonic flaw detection of rail train wheelsets is gradually introducing automatic flaw detection equipment on the basis of manual flaw detection. Manual flaw detection is affected by the skills of flaw detectors, the level of equipment operators, and the status quo of the maintenance environment. The detection efficiency is low and it is easy to misjudge and miss judgment. , there are potential safety hazards, and the automatic flaw detection equipment is limited by the difference in the type of rail trains and the space change of the maintenance trench, which will cause poor adaptability of the detection platform to the site, collision between the carrier and the bottom parts of the vehicle, and the inability to realize the positioning of the carrier, etc.
