Description

A kind of rail test block

Technical field

The utility model relates to inspection technique field, especially relates to a kind of rail test block being applied to railway engineering field rail examination dynamic test.

Background technology

UT (Ultrasonic Testing) is the most widely used general a kind of flaw detection mode in detection technique field, the exploitation of non-destructive detecting device and test, all be unable to do without detected object.The major function of ultrasonic rail flaw detection operation is exactly detect the hurt that rail itself exists, such as: the core of Rail head wound, vertically splitting, the Crack In Bolt Hole in web of the rail portion, flange of rail selenodont hurt, and various welding, hurt etc. caused by fatigue.Therefore, how to concentrate, complete, provide these hurt detected objects all sidedly, be an important ring of Ultrasonic Nondestructive.Domestic have a lot of mould producer to provide multiple hurt test block, but these hurt test blocks have a common feature, are exactly all can only carry out static test, and can not provide dynamic test.At present, the ultrasonic test equipment being applied to railway engineering field mainly contains: defectoscope and rail-defect detector car.Wherein, what rail-defect detector car flaw detection operation adopted is the wheel sensor detection mode that 30 passages are taken turns in 6 spies, framework composition is respectively arranged side by side 3 along the both sides perpendicular to rail-defect detector car traffic direction and visits wheel.At home, steel rail ultrasonic flaw detecting debugging builds a rail defects and failures test wire exactly with the Main Means demarcated, and rail defects and failures test wire simulates various rail defects and failures.Wherein, in the prior art, relevant to the utility model technical scheme master has rail defects and failures calibration line and disk rail test unit.

(1) rail defects and failures calibration line mode is the relatively straight railway line utilizing a section infrequently to use on non-main track, and it is made up of accelerating sections and test section two parts.Wherein, the distance of accelerating sections is at 4 ~ 6 kilometers, and test section adopts the rail of the prefabricated various hurt of 10 12.5 meters to form.Its principal feature is: the test mode adopting " it is motionless that car moves rail ", close to real test environment, has accelerating sections, longer between test section, is applicable to high speed test and its special calibrating.Its shortcoming is: need dedicated line, has requirement to line length, and rail replacement is inconvenient, does not utilize and is integrated in laboratory.In addition, the cost of which is very high, uses the impact being subject to railway dispatching.

(2) disk rail test unit utilizes a ring device, and device edge is the rail of simulation, is provided with various hurt thereon, and test timer centrally rotates, as shown in Figure 1.Disk rail test unit comprises annular rail 201, rail fixed support 202, driving motor 203, speed reduction gearing 204, ring protection wall 205, coupled water nozzle 206, visits wheel unit 207, drainage arrangement 208, coupling water source 209 and power supply and protective device 210.Its principal feature is: the test mode adopting " rail motor-car is motionless ", can reach certain speed, also can arrange a certain amount of hurt thereon.Its shortcoming is: circular rail has larger difference with the actual rail used, and is subject to constraint.Because circular rail can not design very large, use the rail that can not there is small curve radius like this in reality, this damage set-up mode has larger gap with the actual hurt object detected, and is also unfavorable for installing checkout equipment.

Therefore, exploitation one can dynamically provide omnibearing hurt experimental enviroment for rail examination operation, simultaneously easy and simple to handle, arrange flexibly, little, strong adaptability affected by environment, rail test block with low cost become current problem demanding prompt solution.
