Description of the drawings
Fig. 1 is the structural schematic diagram of the present invention.
In figure, 1- yokes, 2- excitation coils, 3- Hall sensor arrays, 4- turntables, 5- turntable motors, the deceleration of 6- turntables
Device.
Specific implementation mode
Technical scheme of the present invention is described in further detail below in conjunction with the accompanying drawings：
As shown in Figure 1, the invention discloses a kind of devices carrying out high speed cruising inspection using turntable simulation rail cracks, including magnetic
Yoke, excitation coil, Hall sensor array, turntable, turntable motor and turntable retarder；
The turntable is made of ferrimagnet, and wall surface is for simulating rail cracks；
The output shaft of the turntable motor is connected by deceleration mechanism and the shaft of the turntable, is carried out for controlling the turntable
Rotation；
The turntable retarder makes it stop operating for slowing down to high-speed rotating turntable；
The yoke takes the shape of the letter U, and is open towards the turntable；
The excitation coil is wrapped in the yoke and is electrically connected with external power supply；
Wall surface of the yoke for when excitation coil is powered towards turntable sends out magnetic signal；
The Hall sensor array is arranged in the yoke, is parallel to the wall surface setting of the turntable, for collecting turntable
Magnetic leakage signal on wall surface.
Specific implementation step is：When turntable works, turntable can generate rotation, turntable surface meeting due to turntable motor
Form one of circumference.If turntable surface has crackle, circumference can be followed and generate movement.On the other hand, due to Hall sensor
Array parallel is arranged in the wall surface of turntable, and in turntable high-speed motion, turntable surface crackle can be when close to electromagnetic probe, a flash
Between it is parallel with Hall sensor array.Angle when detecting rail with Hall sensor array at this time is consistent.Due to high speed turntable
It is formed for ferrimagnet, by applying exciting current to excitation coil, can detect the crack information of turntable surface at this time.
Meanwhile the collected useful signal of Hall sensor array is very faint, and additional hardware blocking amplifying circuit is needed to handle letter
Number.After external hardware processing of circuit, collected in host computer by capture card.Using MATLAB processing, three-dimensional imaging,
It more can clearly observe position and the distribution of defect.
The present invention can be embodied in many different forms, and should not be assumed that be limited to the embodiments described herein.On the contrary,
These embodiments are provided so that the disclosure is thorough and complete, and the model for the present invention being given full expression to those skilled in the art
It encloses.In the accompanying drawings, for the sake of clarity it is exaggerated component.
