Background technology
At present, the main coil of single form that adopts in the magnetization failure detector of wheel shaft quality inspection employing is reached magnetized purpose; Yet there are problems such as the magnetization scope is little, magnetization is even inadequately, do not reach the effect of whole flaw detection.ZL200920105990.X discloses right Magnitizing method of a kind of train wheel and magnetizing assembly thereof, by forming the resultant magnetization of train wheel to, wheel shaft closing up together open-close type solenoid; The effect of this resultant magnetization increases, but owing to form vertical resultant magnetization of week, still can have longitudinal magnetization complex structure, uneven problem, and since to train wheel to direct energising, bad because of the clamping electrode contact, can form sparking electric arc, the damage wheel shaft.
The utility model content
The purpose of this utility model is exactly for a kind of better magnetization effect, energy-conservation, train axle week vertically full induction resultant magnetization system that can realize Non-Destructive Testing to wheel shaft are provided.
The purpose of this utility model can be achieved through the following technical solutions: train axle week is vertically responded to the resultant magnetization system entirely, comprise the drive unit that makes tested wheel shaft rotation and make the magnetized magnetizable body of wheel shaft, described magnetizable body comprises longitudinal magnetization mechanism and circumferential magnetization mechanism.
Two groups of MT longitudinal coils that are provided with before and after described longitudinal magnetization mechanism comprises; Described circumferential magnetization mechanism comprises two groups of circumferential coils that draw magnetic sheet and be arranged on described U type magnetic head two arm places of two symmetries that are provided with on U type magnetic head, its yoke.
Described magnetizable body is arranged on can be along in the whole travel mechanism that guide rail moves.
Described magnetizable body is decided the dedicated trigger circuit supply by weighing apparatus.
The described drive unit that tested wheel shaft is rotated comprises the insulator support of supporting shaft.
Compared with prior art, the utility model beneficial effect is as follows:
1,, realizes full induction resultant magnetization by longitudinal coil method and circumferentially actinobolia combination
2, magnetizable body does not contact with wheel shaft, and wheel shaft need not switched on, and does not form sparking electric arc, and wheel shaft is realized Non-Destructive Testing, streamline continuous detecting; Simultaneously energy-conservation, realized full induction resultant magnetization, demagnetization with little electric current, once finish axle inspection and detect overall process.
