Fig. 2 is schematic circuit diagram schematic diagram of the present invention.
In figure: 1, reservoir push rod; 2, two way cylinder; 3,3 position-5 way electromagnetic valve; 4, ground power supply unit; 5, ECU (Electrical Control Unit); 6, wind regime; 7, storage reservoir; 8, upper electrical contact; 9, the reverse electrode corresponding with upper electrical contact; 10, power filter; 11, current-limiting inductance; 12, rectifying device; 13, relay; 14, two-way transient diode; 15, rectifier bridge; 16, chemical capacitor; 17,24V turns 5V power module; 18, micro controller system; 19, solid-state relay.
The specific embodiment
As shown in Figure 1, reservoir push rod 1 is for controlling the actuating unit of bottom door open and close, when needs open the door or at closing time, ground power supply unit 4 is powered for ECU (Electrical Control Unit) 5, makes ECU (Electrical Control Unit) 5 drive 3 position-5 way electromagnetic valve 3 to complete corresponding operating, and then completes opening or closing of bottom door.Wind regime 6 is whole system air feed (pressure air).Wind regime 6 communicates with storage reservoir 7, in the time of hopper car process ground power supply unit 4, direction during according to ground power supply electrifying, ECU (Electrical Control Unit) 5 can judge now for opening the door or closing the door instruction, and then drive 3 position-5 way electromagnetic valve 3 corresponding coils to obtain electric, connect the gas circuit between one of them epitrochoidal chamber and the storage reservoir 7 in two way cylinder 2, the corresponding epitrochoidal chamber pressurising of two way cylinder 2, in the time of rod chamber air intake in two way cylinder 2, reservoir push rod is regained, and completes the action of closing the door, in the time of rodless cavity air intake in two way cylinder 2, reservoir push rod is released, and completes the action of opening the door.
As shown in Figure 2, on vehicle, arrange one with the upper electrical contact 8 of the car body insulation electrode conductor as ECU (Electrical Control Unit) electric signal input end, track (or car body) in the circuit of control system of the present invention as reverse electrode 9.In the time will opening bottom door, ground power supply unit 4 positive poles are contacted with the upper electrical contact 8 on vehicle, ground power supply unit 4 negative poles contact with track (or car body).In the time will closing bottom door, ground power supply unit 4 negative poles contact with the upper electrical contact 8 on car, and ground power supply unit 4 is anodal to be contacted with track (or car body).The both positive and negative polarity mouth of upper electrical contact 8, track (or car body) and ground power supply unit 4 forms a loop, and to ECU (Electrical Control Unit) power supply, opening the door or needing at closing time power-on time is 1-2 second.Power filter 10 plays the electromagnetic interference and the spark interference that suppress energising and power-off moment, and current-limiting inductance 11 plays filtering radio-frequency interference, suppresses electric current fluctuation.Two-way transient diode 14 can restricted passage ECU (Electrical Control Unit) maximum instantaneous voltage, prevent that overvoltage from causing damage to ECU (Electrical Control Unit).By power filter 10, current-limiting inductance 11, two-way transient diode 14, the input end of ECU (Electrical Control Unit) is formed to three-level protective, made the ECU (Electrical Control Unit) can stable operation.In the time that ECU (Electrical Control Unit) powers on, due to circuit parallel connection, circuit is divided into two-way current signal, and a road electric current drives one of them relay 13 to work through rectifying device 12, sampled signal is provided to micro controller system 18, micro controller system 18 judge that by program this signal is that enabling signal is still closed gate signal after electric.Another road electric current charges and powers to power module 17 to after rectifier bridge 15 rectifications chemical capacitor 16, and after power module 17 conversions, the voltage signal that output can drive micro controller system 18 to work, makes its startup work.After micro controller system 18 work, collect the incoming signal of relay 13, the type that judges this signal by program is still closed bottom door signal for opening bottom door, then send corresponding control signal to solid-state relay 19, solid-state relay 19 will make the corresponding coil of 3 position-5 way electromagnetic valve 3 obtain electric after electric, connect two way cylinder work wind path, realize the object of opening bottom door or closing bottom door.After ground power supply unit power up finishes, chemical capacitor 16 continues micro controller system 18 to power, solid- state relay 19 and 3 position-5 way electromagnetic valve 3 are worked on, when reaching after the predetermined work-hours of 3 position-5 way electromagnetic valve 3, by micro controller system 18, solid-state relay 19 is sent to closing signal, it is quit work, meta is got back in 3 position-5 way electromagnetic valve 3 power-off simultaneously, wind path stops two way cylinder air feed, and bottom door keeps current state.So just complete the operation that bottom door is once opened or closed, realized the function of vehicle drive-through dumping material.
The present invention is including but not limited to above-mentioned embodiment; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
