The specific embodiment
As shown in Figure 1, the automatically controlled pneumatic pipeline system of railway hopper car of the present utility model, comprise pneumatic supervisor 1, the first cut out cock 2, the second cut out cock 20, dirt collector 3, to wind, adjust valve 4, storage reservoir 6, dust filter 9, two-position five-way solenoid directional control valve 8, two way cylinder 7, on pneumatic supervisor, connect a wind path arm 10, on wind path arm, be connected in series successively the first cut out cock, dirt collector, to wind, adjust valve, wind path arm is divided into Liang Ge branch afterwards, Yi Ge branch is connected with storage reservoir, another branch is by the second cut out cock, dust filter is connected with two-position five-way solenoid directional control valve, the two ends of two way cylinder are connected with two-position five-way solenoid directional control valve respectively.In storage reservoir exit, be connected with compression indicator 5, to measure the air pressure in storage reservoir.
Before unloading, open all cut out cocks, wind regime is responsible for by wind path and wind path arm fills wind to storage reservoir, and when compression indicator reaches specified value, power available is switched on and is carried out the open and close door action of bottom door to electromagnetic valve.When two-position five-way electromagnetic switch valve coil II 19 when electric, the wind of storage reservoir enters two way cylinder A end through two-position five-way solenoid directional control valve, B end cylinder compressed air is through two-position five-way solenoid directional control valve discharged to atmosphere, and two way cylinder push rod is released, and then controls door-opening mechanism and realize the action of opening the door.When two-position five-way electromagnetic switch valve coil I obtains when electric, the wind of storage reservoir enters two way cylinder B end through two-position five-way solenoid directional control valve, and A end cylinder compressed air is through electromagnetic valve discharged to atmosphere, and two way cylinder push rod shrinks, and realizes the action of closing the door.
Two-position five-way electromagnetic switch valve coil obtains the electric circuit as shown in Figure 3 that is subject to and controls, and this circuit comprises that two-position five-way electromagnetic switch valve coil I 17, two-position five-way electromagnetic switch valve coil II 19, first are subject to electrical contact 11, second to be subject to electrical contact 13, diode 12,14,15,16 and track (or car body, the earth) 18.The negative pole anodal and 15 of diode 14 is connected by wire with being subject to electrical contact 11,13, the negative pole of diode 14 is connected with two-position five-way electromagnetic switch valve coil II, diode 12 is in parallel with two-position five-way electromagnetic switch valve coil II, and negative pole is connected with the negative pole of diode 14; The positive pole of diode 15 is connected with two-position five-way electromagnetic switch valve coil I, and diode 16 is in parallel with two-position five-way electromagnetic switch valve coil I, and positive pole is connected with the positive pole of diode 15; Two two-position five-way electromagnetic switch valve coils are connected by wire and track (or car body, the earth).
When first segment hopper car enters behind loading dock, the positive pole contact first of first group of power supply is subject to electrical contact, negative pole joining rails, flow through diode 14 and two-position five-way electromagnetic switch valve coil II of electric current, and with first be subject to electrical contact and track to form loop, now two-position five-way electromagnetic switch valve coil II obtains electricly, and reservoir push rod is released, and realizes the unlatching of hopper wagon bottom door.Be subject to electrical contact to leave moment of first group of power supply when first, two-position five-way electromagnetic switch valve coil II forms larger inducing current, and direction of current is identical with the front direction of current of power-off.12 of diodes have played shunting action, make most of electric current flow through diode 12 and two-position five-way electromagnetic switch valve coil II, and only has the less electric current two-position five-way electromagnetic switch valve coil I of flowing through, stem position in two-position five-way solenoid directional control valve still keeps the front state of power-off like this, guarantees the reliability of power-off moment door opening state.
After discharged, vehicle enters the district of closing the door, the anodal joining rails of second group of ground power supply, negative pole contact second is subject to electrical contact, flow through two-position five-way electromagnetic switch valve coil I and diode 15 of electric current, and with second be subject to electrical contact and track to form loop, now two-position five-way electromagnetic switch valve coil I obtains electric, reservoir push rod shrinks, and realizes closing of hopper wagon bottom door.Be subject to electrical contact to leave the moment of second group of power supply when second, the effect of diode 16 is identical with the effect of diode 14, keeps two-position five-way solenoid directional control valve state constant, guarantees the close the door reliability of state of power-off moment.
Repeat said process, can realize permutation hopper car and uninterruptedly unload, and complete the action of closing the door.
When ground power supply cannot supply regular power, can people be to press the open and close that hand push button on two-position five-way solenoid directional control valve is realized hopper wagon bottom door.
