Description
Technical field
The present invention relates to wheel rim inspection technique field, especially relate to a kind of high ferro wheel rim and automatically detect immersion probe.
Background technology
Train is the important tool of current people trip, and the speed goes of train is fast.Along with improving constantly of train speed, the security of train running more and more causes the concern of people, it is also proposed higher requirement to the performance of train various piece, quality.Wheel is the important motion of train and load bearing component, and its quality good or not is to ensureing that the safe operation of train plays vital effect, once accidents caused, catastrophic often.Defect in train wheel, especially wheel tread crackle are accidents caused huge hidden danger.Undoubtedly, if this type of defect can not effectively detect as early as possible and take measures in time, along with the further speed-raising of train, wheel operation conditions worsen further, the accident caused thus can be on the increase, and consequence is hardly imaginable.
When current train generally raises speed, realize the flaw detection to in-service train wheel, in order to regularly to monitor wheel mass situation, eliminate accident potential, become the major issue that world is attracted attention jointly.
Traditional in-service train wheel inspection technique example inspection, Duan Jian, light maintenance, overhaul are the final routine business of railroad.And the quality testing of in-service wheel is generally carried out when overhaul.The wheel detection means of usual employing, based on UT (Ultrasonic Testing) and magnetic powder inspection.Traditional wheel UT (Ultrasonic Testing) adopts piezoelectric supersonic normal beam technique, there is significant limitation mainly for detection of inside wheel defect the method.First be low to the detection sensitivity of the radial defect of wheel, and the critical defect that radial defect causes wheel spalling even to burst apart exactly; Next operates too complexity, especially when train does not disintegrate, comprehensive scanning to be carried out difficult especially to wheel, due to wheel major part hide by miscellaneous part, thus flaw detection can only be carried out stage by stage, namely on one side motor-car is detected a flaw on one side, and a chassis need can complete flaw detection operation through repeatedly movement sometimes.And the more important thing is, for piezoelectric supersonic normal beam technique, under wheel tread and tread, 10mm inner region belongs to check frequency, cannot detect, still not have very good detection means to the inspection in this region.
Summary of the invention
The technical problem to be solved in the present invention is: too complicated in order to overcome the flaw detection operation of defect detection on ultrasonic basis traditional in prior art to train wheel, flaw detection difficulty is large, and 10mm inner region belongs to check frequency under wheel tread and tread, the problem that cannot detect, provides a kind of high ferro wheel rim automatically to detect immersion probe.
The technical solution adopted for the present invention to solve the technical problems is: a kind of high ferro wheel rim detects immersion probe automatically, comprise two tracks, flexible member and probes, described two parallel tracks are arranged, described two tracks all have groove, in described groove, flexible member is set, some described probes are single-row to be disposed side by side on flexible member, adjacent two described probe Contacts connect, the upper surface of some described probes is all higher than the upper surface of track, and the overall length of some described probes is more than or equal to the girth of high ferro wheel rim.
Further, the bottom shape of described groove is rectangle, the width of described groove equals the width of popping one's head in, the length of described groove equals the overall length of some described probes, some probes can be made like this to be embedded in groove, probe is only moved in the height direction, limit the movement of probe on width and length direction, pop one's head in more stable in flaw detection process, make detection more accurate.
Further, described flexible member is spring, and some described springs are fixedly distributed on groove lower surface.
In order to make installation simpler, quick, described flexible member is rubber blanket, and the shape of described rubber blanket is identical with bottom portion of groove shape.
The invention has the beneficial effects as follows: the length of the probe in the present invention is more than or equal to the length of high ferro wheel rim, after high ferro wheel rim rotates a circle, carrying out flaw detection also completes, simple and fast; Be provided with flexible member below probe, make probe be adjacent to high ferro wheel rim, detection more accurate; Utilize water to do medium, strong solve wheel tread and tread under 10mm inner region belong to check frequency, the problem that cannot detect.

Embodiment
The present invention will be further described in detail by reference to the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
Embodiment 1:
A kind of high ferro wheel rim as Figure 1-4 detects immersion probe automatically, comprise two track 1, flexible member and probes 2, article two, track 1 be arranged in parallel, article two, track 1 all has groove 3, the bottom shape of groove 3 is rectangle, the width of groove 3 equals the width of probe 2, the length of groove 3 equals the overall length of some probes 2, some probes 2 can be made like this to be embedded in groove 3, probe 2 is only moved in the height direction, limit the movement of probe 2 on width and length direction, probe 2 is more stable in flaw detection process, makes detection more accurate.
In groove 3, flexible member is set, flexible member is spring 5, some springs 5 are fixedly distributed on groove 3 lower surface, some probes 2 are single-row to be disposed side by side on spring 5, adjacent two probe 2 Contacts connect, the upper surface of some probes 2 is all higher than the upper surface of track 1, and the overall length of some probes 2 is more than or equal to the girth of high ferro wheel rim 4.
