Description
Technical field
The present invention relates to a kind of detection tool used in rail vehicle truck production and maintenance process, particularly one kind
Multi-functional wheel tread contour detects model.
Background technology
Wheel is the critical component of rail vehicle operation, directly affects the safety of vehicle operation.And match somebody with somebody on wheel with rail
The profile and size of the tread portions of conjunction are even more important.
When abrasion or abnormal defect occur in operation for wheel track, tread contour and size will be caused to change.Tread
The change of profile and size, once wheel track abnormal vibrations may can be caused or even derail by transfiniting.Therefore operation goal is determined
Phase is strictly monitored to wheel, checks tread surface state, measures overall size.
Tread contour and dimensional gaughing, the project that need to generally detect have：Whether Qr values transfinite, whether flange height exceedes,
Flange thickness whether within prescribed limit, rim surface whether have heave and heave whether superelevation, and tread surface lack
Whether sunken length transfinites etc..
In the prior art, it is the above-mentioned various projects of detection, once maintenance need to carry a variety of detection instruments, such as ruler, a variety of
Dedicated test measurer that the slide measure and detection end item of model use etc..
Above-mentioned detection instrument used in prior art, in practice maintenance process, there is following deficiency：
1. on the one hand it is inconvenient to carry, detection it is cumbersome, part dedicated test measurer is expensive, complex operation, rapid wear, it is necessary to
The special storehouse of special messenger preserves, regular censorship.
2. on the other hand, above-mentioned detection tool is measurer, is quantitative measurment, can detect specific numerical value.For detection
Some project as a result, it is desirable to spend the longer time cycle.And in maintenance, vehicle fleet size is more, also has to the repair time
Time restriction, to finish the maintenance of all items within the defined time, it is necessary to put into more manpower, manpower is added indirectly
Cost, and artificial error in measurement is larger, and reliability is relatively low.
Tread contour and all detection projects of dimensional gaughing, in analysis and assessment, typical time is longer, estimation half a year with
On, just need to carry out a quantitative measurment, specific numerical value need to be detected.In daily maintenance, we only need observational measurement,
Namely judge whether wheel tread surface state and size transfinite, and do not need specific numerical value.
If it is possible to develop a kind of detection model, the detection sample is easy to carry, can measure simple and fast,
By formula, without reading, namely during detection, it only need to judge whether profile or size transfinite, not transfinite as qualified.So, will
Overhaul efficiency can be greatly improved, reduces the cost of overhaul, marketing and application value are high.
The content of the invention
In view of the above-mentioned deficiencies of the prior art, the technical problem to be solved by the present invention is to provide a kind of multi-functional wheel is stepped on
