Above-mentioned high speed train wheel can also detect the train operating conditions such as unbalance loading, overload, transverse force of train to dynamic detection system, concrete detection principle is that detection wheel is to the transverse force by the detection train operation, and then the derailing coefficient when doping the train high-speed cruising, and then can improve train traffic safety.
The high speed train wheel that the embodiment of the invention provides is gathered the data detection signal of wheel tread situation by detecting device on the rail to dynamic detection system, when train moves on rail, because wheel weight can make rail bend, its degree of crook is relevant with the power that wheel acts on the rail, thereby the laser beam that laser sensor is sent is offset, its departure distance is relevant with the sinuousness of rail, and then the power that acts on the rail with wheel is relevant, cross the deformation variation of car front and back and calculate the right defect information of wheel according to rail in conjunction with wheel rail relation, promptly can calculate the scratch of wheel tread, thread defects such as shelled tread and tread out of roundness can detect the super unbalance loading of train in addition, operation conditionss such as transverse force.The high speed train wheel that the embodiment of the invention provides is a detecting device on the rail to the core detection part of dynamic detection system, it is installed in the bottom of rail, need not rail is carried out destructiveness transformation, simultaneously, detecting device can acquire the relevant information of train on the rail when the train high-speed cruising, and its inner related device aseismicity is good, can adapt to the high-speed cruising environment, this system's testing process full automaticity carries out, the detection efficiency height, therefore can be applicable to the high-speed cruising train.
Referring to Fig. 2, the structural representation of detecting device on the rail that present embodiment provides, detecting device comprises on this rail: be successively set on system's upper electrical switch 11, axletree counter switch 12, laser sensor group 13, license number identification module 14 on the train direct of travel.
Described system upper electrical switch 11 is arranged on wherein one the inboard in two one steel rails 5, when train arrives, triggers described system and gets electricly, makes described system be in readiness for action, the preparation for acquiring data.
When the described system of train wheel process upper electrical switch 11, the electric signal of system's upper electrical switch 11 output can change, the electric signal of this variation can triggering system get electric, particularly, can realize by electromagnetic sensor, also can realize by laser sensor or edd current transducer.
Described laser sensor group 13 is made up of 12 laser sensors at least, and the laser sensor number that is provided with on two one steel rails is identical, is that example carries out laser sensor group 13 is described with 12 laser sensors:
Every one steel rail is provided with 6 laser sensors, each laser sensor is responsible for the detection of the wheel tread circumference of about 700mm length, 6 laser sensors just can detect the circumferential distance that is about 4200mm, and the circumferential length of a wheel is less than 4200mm, and promptly 6 laser sensors just can detect the tread distance of at least one circumference of wheel of arbitrary diameter.
Need to prove that the number of laser sensor is not limited to 12, as long as the distance of at least one circumference that can inspection vehicle wheel tread circumference; Number of sensors can detect two or more tread circumference of wheel like this more than 12, and then realizes that a plurality of sensor go out same wheel information, so that testing result is more accurate.
During concrete enforcement, referring to Fig. 3 and Fig. 4, Fig. 3 is the scheme of installation of a kind of laser sensor of the embodiment of the invention; Fig. 4 is the sectional structure scheme drawing of a kind of laser sensor of the embodiment of the invention.
Laser sensor comprises laser transimitter 6, laser pickoff 7 and pillar 8.As shown in Figure 3, laser transimitter 6 and laser pickoff 7 are installed on the bottom of an one steel rail by rail clip 9, and concrete, described rail clip 9 can be fixed on the rail foot by bolt of rear end plate, install simply, and do not need rail is done destructive the transformation.And laser pickoff 7 is arranged on the place ahead of laser transimitter 6, so that wheel is earlier through laser transimitter 6.Pillar 8 is used to protect described laser transimitter 6 and described laser pickoff 7 in-to-in optics.
Described laser sensor sensitivity is better, and the minimum load that can record is 10kg, obtains deformational displacement even finger also can be detected by laser sensor by the deformation quantity that rail is taken place.Simultaneously, the measurement range of the laser pickoff in the laser sensor is bigger, and when a column weight reached 10 tons train wheel process laser sensor top, the measured displacement of laser pickoff only accounted for 10% of its whole measurement range, therefore, this laser sensor can be applicable to the train of various load.
The concrete working process of above-mentioned laser sensor is as follows:
The laser beam that laser transimitter 6 sends under the normal circumstances is beaten the RC position at laser pickoff 7; Through out-of-date, cause rail distortion because wheel rolls rail as train, it is relevant that its degree of crook and wheel act on the distance and the wheel in-service time of application force, laser beam initial position and laser pickoff center-point of rail.Thereby, laser transimitter 6 emission laser beam directions are offset, make and beat in the generation displacement of the laser beam position of PSD laser pickoff 7 along plane, rail place.
Described laser pickoff 7 can be PSD (Position Sensitive Device, a high accuracy displacement sensor) laser pickoff, vertically is arranged on the rail, promptly can respond to laser beam out-of-position displacement up and down.Its fundamental diagram as shown in Figure 5, the output voltage of two ends up and down of described laser pickoff 7 is respectively U1 and U2, and U1 and U2 sum are constant.When laser beam is beaten positive center at laser pickoff 7, U1=U2; When laser beam offset downward, U1 increased, U2 reduces; When laser beam upwards was offset, U1 reduced, and U2 increases.
When train no show laser sensor, rail makes and the contacted rail of wheel is bent downwardly because wheel rolls, but the laser beam that the laser transimitter 6 that is positioned at wheel the place ahead sends is skew upwards, makes the U1 of laser pickoff 7 outputs reduce, and U2 increases; When wheel movement arrives the top of laser transimitter 6, because laser transimitter 6 and laser pickoff 7 are separately fixed at the rail place near sleeper, therefore the bearing capacity of wheel is mainly born by sleeper, and this moment, rail was not crooked substantially, so the laser beam non-migration that sends of laser transimitter; When wheel movement arrives the top of laser transimitter 6, because the wheel bearing capacity makes the rail that contacts with wheel produce deformation, promptly rail is bent downwardly, and the laser beam that causes laser transimitter 6 to send offsets downward, thereby the U1 of laser pickoff 7 outputs is increased, and U2 reduces.
Preferably, laser sensor offers described data processing unit 3 through the electric signal of out-of-date overall process through described rail limit adapter unit 2 with wheel, data processing unit utilizes following formula to calculate the corresponding curve of wheel tread circumference detected status according to U1 that receives and the numerical value of U2:
K is the direct proportion coefficient in the above-mentioned formula, and U1 and U2 are the magnitude of voltage of laser pickoff 7 outputs.
Because U1+U2 is a constant, it is a parabolical shape that Open Side Down that the measured wheel of laser sensor detects corresponding curve through hour wheel to the tread circumference.
When there is tread damage in wheel, promptly when flat sliding or shelled tread, the detection curve that corresponding laser sensor position obtains will produce moment waveform saltus step, rather than smooth parabola.When there is tread damage in wheel, during wheel tread injury region contact rail, this moment only be the tread damage place a bit contact rail, wheel is that fulcrum rotates with this point, wheel has the trend of soaring in rotation process, thereby the pressure that rail is subjected to wheel can diminish, the deformation of rail reduces, the side-play amount of the laser beam that laser transimitter sends reduces, and when the wheel tread injury region left rail, the downward impulsive force of wheel increased, the deformation of rail increases, the side-play amount of the laser beam that laser transimitter sends increases, and being reflected on the curve is exactly the variation that a waveform is jumped, rather than level and smooth parabolical shape.
Judge the size of the damage that produces according to the extreme value that produces saltus step place on the curve, can judge the number of wheel damage according to moment waveform saltus step number in the measured curve.
A laser sensor is responsible for the wheel tread circumference detection of about 700mm, 6 six measured curves of laser sensor just can reflect the tread circumference situation of whole wheel, when wheel during than out of roundness, six sensors record the cooresponding curve of data and are level and smooth parabolic shape, and these six basic in-lines in parabolical summit, when there is the defective of out of roundness in wheel tread, fluctuate up and down in described six parabolical summits, can calculate the size of wheel out of round degree according to these six parabolical summit fluctuation situations.
License number identification module 14 is arranged between two one steel rails 5, and this license number identification module 14 can be arranged on the place ahead of system's upper electrical switch 11, and in the present embodiment, license number identification module 14 is arranged on the place ahead of laser sensor group 13.
Since can be on every railway line through a lot of trains, this license number identification module 14 is used for determining that laser sensor group 13 detects the cooresponding train of wheel tread information that obtains.Concrete, train is provided with the electronic tag that comprises train license number essential information, license number identification module 14 can read this label and therefrom obtain the vehicle number information of train, thereby can determine that laser sensor group 13 detects the cooresponding train of wheel tread information that obtains, and this license number identification module 14 can obtain the license number of the train of high-speed cruising, is that detecting device is applicable to one of prerequisite of high speed train on the described rail.
Need to prove, laser pickoff in the embodiment of the invention 7 can be horizontally installed on the place ahead of laser transimitter 6, laser transimitter 6 emitted laser are beaten in the plane that is parallel to the sleeper place on laser pickoff 7, be that laser beam is offset in the horizontal direction, at this moment, can be used for detecting transverse force, when train is being turned or because cargo loading when inhomogeneous, wheel can produce and swing, and then generation transverse force, this transverse force produces rail to a certain extent and destroys, the derailing coefficient during therefore by the operation of detection transverse force predictable column overall height speed.
In addition, the high speed train wheel that the embodiment of the invention provides is to dynamic detection system, do not need to be equipped with the calibration train and come corrective system, has self-correcting function, this system can calibrate automatically by the known train of weight, when train passes through this system at every turn, system is with the load-carrying of train, in data such as temperature and the speed data-in storehouse, all can be when described system is calculated at every turn in conjunction with the data cases of nearest 100-200 train number of record, utilize correlation parameter such as train load parameter from dynamic correction when inferior testing result.
In sum, high speed train that the embodiment of the invention provides wheel is gathered the tread condition information of wheel to dynamic detection system by laser sensor, the data message that is collected through data processing unit handle and data analysis after can obtain train wheel tread information.The installation of described system is simple, and is easy to maintenance, and do not need railway roadbed and rail are done any destructive transformation, and this system goes for the speed range of 60-400km/h, and speed is applied widely; The testing process full automaticity of this system carries out, and has self-correcting function, the detection efficiency height, and the common train detection time is below 2min.Described system can also directly be presented at testing result on the display equipment, intuitively shows information such as defective wheel position and defect size, can also show testing result with the form of webpage.
