The bogie brake is stepped on the brake tile style mechanical brake device and electromagnetic brake brake apparatus using foot；The foot is stepped on the brake watt
Formula mechanical brake device is mounted on chauffeur position, prevents from being controlled by what artificial foot was stepped on；The electromagnetic brake braking
Device controls start and stop by the bogie brake control button；The servomechanism installation is controlled by the servomechanism installation control button
Start and stop；It is described sweep stone implement by it is described sweep stone implement control button control start and stop；
The spray coupling device controls start and stop by the spray coupling device control button, is connected with water tank by pipeline；
Coupling liquid in the water tank is sprayed at rail surface by spray head by the spray coupling device, make ultrasonic energy preferably into
Enter rail interiors, to guarantee that the ultrasonic wave visits the coupling for taking turns to rail to the lossless propagation for neutralizing ultrasonic wave.
9. double rail type ultrasonic fault detection system as described in claim 1, it is characterised in that: the ultrasonic wave, which visits wheel, has a pair
And the vehicle frame bottom side of the trolley body is mounted on by spy wheel support；It is pre- that each ultrasonic wave spy wheel is also equipped with centering
Tight device, the centering pre-tightening apparatus are mounted on above the spy wheel support；The centering pre-tightening apparatus is additionally provided with described in control
Ultrasonic wave visits the spring of pressure between wheel and rail, is visited between wheel and rail by adjusting the spring to adjust the ultrasonic wave
Pressure.
10. double rail type ultrasonic fault detection system as claimed in claim 2, it is characterised in that: the ultrasonic wave sends and receives
Data collecting plate card also equipped with echo and depth of defect Real time displaying software, passes through the echo and depth of defect Real time displaying
Software can immediately judge rail hurt；
The echo and depth of defect Real time displaying software mainly include data acquisition module, A sweeps drafting module, defect calculates mould
Block, defect buffer zone module and defect memory module；
The data acquisition module is used to carry out data acquisition to ultrasonic echo signal, by the A/D conversion module by mould
Quasi- echo-signal is converted into digital signal and is stored and transmitted；
The A sweeps drafting module for the digital signal after converting the A/D conversion module by way of Image Rendering, real
When be shown on the panel of the echo and depth of defect Real time displaying software, image horizontal axis represent detection depth, the longitudinal axis represent
Echo wave height；
The defect computing module is used to analyze echo-signal and default defect gate parameter comparison, judges that echo whether there is
Defect information, if it is present defect information is kept in defect buffer area；
The defect buffer zone module, when buffer area is full, sends buffer area full scale will for caching the defects of echo information
Signal；
The defect memory module expires marking signal for receiving buffer area, when defect buffer area is full, reads in buffer area
Defect information is simultaneously packaged into system disk space, flush buffers, and waiting is read next time.
