Description
Technical field
The present invention relates to a kind of double-manipulator rail vehicle flaw detection equipment, especially a kind of do not fall under wheel situation to a wheel on two wheels carry out the defectoscope of UT (Ultrasonic Testing) simultaneously.
Background technology
Recent domestic has been developed one and has not been fallen to taking turns ultrasonic test equipment, wheel need not be removed, but under the normal mounted in a vehicle state of wheel, carry out automatic flaw detection by defectoscope mobile in trench at the bottom of car.Existing ultrasonic flaw-detecting machine has two kinds of forms.One is that defectoscope chassis middle part arranges a lift master, and a track parallel with stock rail is arranged at lift master top, and a planker that tread wheel rim associating probe holder is housed moves on this track.Mechanical arm on planker leans against probe holder on wheel simultaneously, and support roller drives vehicle wheel rotation just can detect a flaw again.The defectoscope of this form subject matter is in use that its moving component is mainly arranged in lift master top, complex structure, highly higher, in probe movement process, can interfere collision with the bottom of some type of vehicle, make can not use this ultrasonic flaw-detecting machine in a part of vehicle, be difficult to the various vehicle of compatible domestic model.
The defectoscope of the second form has a tread probe holder and two wheel rim probe holders.There is a rotary disk at its chassis middle part, on rotary disk lift master after, the mechanical arm of a clamping tread probe holder is housed, two wheel rim probe holders are arranged on respectively chassis both sides.The major defect of this defectoscope is because mechanical arm is at the rear side of lift master, and two wheels of a bogie between do not have mechanical arm to turn round required space, so can only wheel detect a flaw to outside.Make to survey the wheel of another direction of bogie, defectoscope can only be moved to beyond a train end, then defectoscope rotary disk is rotated after 180 degree, make mechanical arm forward lift master front side to, chassis negative line feed could be detected a flaw.
Two kinds of defectoscopes of the prior art can only be detected a flaw to the wheel of upper one end to a wheel at every turn above, can not survey two ends wheel simultaneously, operation inconvenience, and efficiency is low.These problems are only improved and cannot thoroughly be solved current equipment, need to invent a kind of different defect-detecting equipment.
