Description
Technical field
The present invention relates to detection technique, is a kind of center support system and method for steel rail flaw detection device concretely.
Background technology
The function of rail is that guided vehicle wheel advances, and bears the immense pressure from wheel.In-service rail bears repeatedly rolling of wheel for a long time, inevitably there is fatigue defect and defect.Therefore in order to ensure the safe operation of locomotive, need often to carry out carrying out flaw detection to in-service rail, there is the hurt in rail in Timeliness coverage, to adopt remedial measures, takes precautions against in possible trouble.
Ultrasonic rail inspection car detects rail defects and failures according to the ultrasonic echo of rail defects and failures reflection, when using ultrasonic probe to carry out rail examination, 0 degree of ultrasonic probe must be made to aim at the geometric center lines of rail section.When ultrasonic probe aims at rail section center line, as shown in Figure 1, if rail does not have hurt, ultrasonic probe can receive stronger flange of rail echo (end ripple) signal, if rail has hurt ultrasonic probe will receive hurt echoed signal, thus detects the hurt of rail; And when ultrasonic probe departs from rail, as shown in Figure 2, end ripple signal intensity will weaken and even disappears, be thus just difficult to even can not detect rail defects and failures.
Due to circuit irregularity and take turns right serpentine locomotion, rail-defect detector car is detected a flaw when advancing on the line inevitably yaw, yaw motion, if ultrasonic probe is directly contained on inspection car car body, this transverse movement of car body makes ultrasonic probe be difficult to aim at rail, and the catenary motion of car body is also very large, ultrasonic probe is also difficult to adapt to.
In prior art, for reducing the vertical and transverse movement of car body to the impact of ultrasonic inspection, ultrasonic probe is generally all arranged on flaw detection traveling dolly, and the transverse direction of traveling dolly and catenary motion are much smaller compared with the motion of inspection car car body.Rail is aimed at, the mechanical expanding wheel construction of low speed flaw detection trolley many employings changeable wheelbase for making ultrasonic probe.As shown in Figure 3, the pressure gas that cylinder 301 rear end passes to certain pressure is followed the tracks of when giving, cylinder just acts on the wheel that rises on 302 pressure, thus the right wheel rim of wheel that makes to rise is close to inside the rail head of rail 303 all the time, the wheel that rises like this aims at rail center all the time to center, and visit wheel carrier Shang Tanlun center and Zhang Lundui center is in same longitudinal surface, therefore ensure that and visit wheel central plane and rail central plane overlaps, thus realize probe centering.
Adopt the mode centering of mechanical expanding wheel, though simple and reliable for structure, good centering requirement can be realized when detecting a flaw traveling dolly slow running, but along with the raising of travelling speed, the lateral movement velocity of taking turns that rises improves thereupon, because transverse acceleration increases with the square law of speed, so the horizontal centering acting force of probe needed for centering is along with the raising meeting increase fast of speed.When inspection car travelling speed brings up to 80km/h by 40km/h, the lateral movement velocity of dolly is original 2 times, and horizontal centering acting force is then original 4 times, and this very large transverse force is very disadvantageous for the safe traveling of flaw detection trolley.
Further, in prior art, for realizing rail examination under high-speed cruising condition, steel rail flaw detection device is arranged on below bogie, and adopt electromagnetic sensor to measure to visit the position deviation of wheel and rail center line, servo control mechanism controls to visit the lateral attitude of wheel on rail.
Electromagnetic sensor may have current vortex sensor group and differential transformer two kinds of modes, the group of current vortex sensor shown in Fig. 4 centering schematic diagram, differential transformer centering schematic diagram as shown in Figure 5 by metering system.
The horizontal centering sensor of the current vortex sensor group of Fig. 4 is adopted to reflect horizontal relative deviation by the output signal deviation of two current vortex sensors, when sensor group is to rail center, the output voltage of two eddy current probes is consistent, voltage deviation is 0, the output signal that sensor group departs from two eddy current probes in rail center just has deviation, it is more that sensor departs from rail center, then deviation output voltage is larger, and such two current vortex sensors just constitute a centering sensor.
When adopting the differential transformer of Fig. 5, rail has just become to do the dynamic iron core of differential transformer, as added driving voltage on intermediate coil, when sensor is to rail center, the induced voltage of two secondary windings is identical, when sensor departs from rail, the induced voltage of two secondary windings will be variant, and two limit induced voltage signals are carried out processing the output signal that just can obtain a reflection relative deviation.
In prior art, adopt electromagnetic sensor measuring position deviation, servo control mechanism controls to visit the mode that wheel position realizes centering, because in-service steel rail line is laid on field, expose to the sun and rain, invariably cannot can produce corrosion, electromagnetic sensor, owing to having ferromagnetism, therefore can attract iron rust to come up and glue on a sensor, through after a while, electromagnetic sensor will be stained with iron rust, cause electromagnetic sensor to lose efficacy, thus cause center support system to lose efficacy.
Summary of the invention
