Description
Technical field
The present invention relates to the one detection tool that rail vehicle truck is produced and used in maintenance process, particularly a kind of multi-functional wheel tread contour detects model.
Background technology
Wheel is the critical component that rail vehicle runs, and directly affects the safety of vehicle operating.And the profile of the tread portions that wheel coordinates with rail and size are even more important.
When wheel track is in operation generation abrasion or abnormal defect, tread contour and size will be caused to change.The change of tread contour and size, just may cause wheel track abnormal vibrations even to derail once transfinite.Therefore run goal regularly strictly to monitor wheel, check tread surface state, measure overall size.
Tread contour and dimension inspection, the usual project that need detect has: whether Qr value transfinites, whether flange height exceedes, flange thickness whether within specialized range, whether rim surface has heaves and heave whether superelevation, and whether the defect length of tread surface transfinites etc.
In prior art, for detecting above-mentioned various project, once maintenance need carry multiple testing tool, as the vernier caliper and the dedicated test measurer detecting end item use etc. of ruler, Multiple Type.
The above-mentioned testing tool that prior art uses, in practice maintenance process, also exists following deficiency:
1. inconvenience is carried in an aspect, detects loaded down with trivial details, and part dedicated test measurer is expensive, complicated operation, rapid wear, needs special messenger's special storehouse preservation, regularly censorship.
2. on the other hand, above-mentioned detection tool is measurer, is quantitative measurment, can detects concrete numerical value.For detecting the result of some projects, need the time cycle that cost is longer.And when overhauling, vehicle fleet size is many, also limits if having time the repair time, for finishing the maintenance of all items in official hour, needing to drop into more manpower, indirectly adding human cost, and artificial error in measurement is comparatively large, reliability is on the low side.
All test items of tread contour and dimension inspection, when analysis and assessment, the general time is longer, estimates half a year more than, just needs to carry out a quantitative measurment, need detect concrete numerical value.In daily maintenance, we only need observational measurement, also namely judge whether wheel tread surface state and size transfinite, and do not need concrete numerical value.
Therefore, if can develop a kind of detection model, this detection sample is easy to carry, can measure on simple and fast ground, through type, without the need to reading, when also namely detecting, only need judge whether profile or size transfinite, and not transfiniting, it is qualified to be.Like this, significantly can improve overhaul efficiency, reduce the cost of overhaul, marketing and using value high.
