Accompanying drawing explanation
Fig. 1 is the structural representation of rail vehicle skate control circuit;
Fig. 2 is the functional block diagram of rail vehicle skate control circuit.
Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with the utility model specific embodiment and corresponding accompanying drawing, technical solutions of the utility model are clearly and completely described.
With reference to Fig. 1 and 2, rail vehicle skate control circuit workflow is as follows:
A, when rail vehicle two ends skate all hangs on rail vehicle vehicle frame, two skates do not work, its workflow is: one end is started power lock SK1 and close, rectifier diode D1 forward conduction, rectifier diode D2 repercussion ends, skate gravity switch TXK1 and TXK2 disconnects, two indicator lamp LHZD1 and two indicator lamp LHZD2 power-off are extinguished, the normally closed main contact of normally closed DC contactor KM1 power-off is failure to actuate, one end forward/backward shelves universal seclector LW1 and two ends forward/backward shelves universal seclector LW2 keeps "on" position, and now driver at any time can motor-car.
B, when rail vehicle one end skate hangs on rail vehicle vehicle frame, skate gravity switch TXK1 does not work, when two end skates are beaten on rail surface, its workflow is: one end is started electric lock SK1 and close, rectifier diode D1 forward conduction, rectifier diode D2 repercussion ends, skate gravity switch TXK2 connects under the Action of Gravity Field of skate, two indicator lamp LHZD2 obtain electric lighting, normally closed DC contactor KM1 negative pole obtains and electric normally closed main contact is disconnected, one end forward/backward shelves universal seclector LW1 and two ends forward/backward shelves universal seclector LW2 power-off make rail vehicle start, thus play the effect stoping and drive to avoid unexpected generation.
C, when rail vehicle two skate is all beaten on rail surface, skate gravity switch TXK1 and TXK2 works, its workflow is: one end is started power lock SK1 and close, rectifier diode D1 forward conduction, rectifier diode D2 repercussion ends, skate gravity switch TXK1 and TXK2 connects → two indicator lamp LHZD1 and two indicator lamp LHZD2 and obtains electric lighting under the Action of Gravity Field of skate, normally closed DC contactor KM1 negative pole obtains and electric normally closed main contact is disconnected, one end forward/backward shelves universal seclector LW1 and two ends forward/backward shelves universal seclector LW2 power-off make rail vehicle start, thus play the effect stoping and drive to avoid unexpected generation.
D, situation about all damaging if there is two skate gravity switch TXK1 and TXK2, its workflow is: press emergency button YSB when skate is killed by rail vehicle wheel and indicator lamp LHZD is lighted, forward/backward shelves universal seclector LW is used rail vehicle to be advanced or retreats, the skate pushed down by rail vehicle wheel is taken out, recovers emergency button YSB and indicator lamp LHZD is extinguished.The principle of work of emergency button YSB is, its direct short circuit main contactor of normally closed DC contactor KM1, makes normally closed DC contactor KM1 ineffective.
Skate gravity switch TXK is arranged on inside the afterbody of skate, and uses HC704 silica gel sealing, can play the effect of damping and insulation, and can weather proof knock with anti-.Be parallel with skate gravity switch TXK1 and skate gravity switch TXK2 inside skate afterbody, one of them skate gravity switch has been broken and has been also had another to work, and so just substantially increases the stability of skate control circuit.Skate gravity switch being installed without the need to changing skate, greatly reducing cost of installation.This design on control circuit is succinct understandable easy to operate, and original paper number is few, cost is low, low in energy consumption, only just consume atomic electricity when track turner is done, this control circuit not power consumption when rail vehicle does not work at ordinary times.
Above-mentioned embodiment is used for explaining and the utility model is described; instead of the utility model is limited; in the protection domain of spirit of the present utility model and claim, any amendment make the utility model and change, all fall into protection domain of the present utility model.
