A front pedal internal contracting brake switch, a rear pedal loosing brake switch and a locomotive speed control system are connected with a PLC (Programmable Logic Controller); the PLC is connected with a first relay and a second relay; the first relay is corresponding to the front pedal internal contracting brake switch and the locomotive speed control system; the second relay is corresponding to the rear pedal internal contracting brake; the first relay and the second relay are connected with a brake motor forward and reverse controller which is connected with a brake motor; the brake motor is connected with an electric driving pushing rod; the current output end of the brake motor is connected with a direct current transformer which is connected with the PLC; the electric locomotive is provided with a red light signal acquisition card which is connected with the locomotive speed control system. The closed-loop braking system of the electric locomotive is sensitive in control and convenient to operate.
Description
Technical field
The utility model relates to the braking technology field of electric locomotive, relates in particular to a kind of electric locomotive closed loop brake system.
Background technology
The brake equipment of locomotive mostly adopts aerobraking and mechanical braking at present, and the greatest drawback of aerobraking is that pneumatic circuit often leaks gas, keeps in repair inconvenience and the large problem of work capacity; Mechanical brake device adopts handwheel, and by the braking of connecting rod brake shoe formula, empty moving stroke is large, operation is heavy, stopping distance is long and easily cause and slide, the requirement while being difficult to meet the locomotive emergency braking.
The utility model content
The utility model purpose is exactly in order to make up the defect of prior art, and a kind of electric locomotive closed loop brake system is provided.
The utility model is achieved through the following technical solutions:
A kind of electric locomotive closed loop brake system, include the front pedal band-type brake switch of electric locomotive, the rear treadle switch that declutches, the locomotive speed control system, the lock motor, lock positive and negative rotating controller for motor and electric pushrod, described front pedal band-type brake switch, the rear treadle switch that declutches is connected with the PLC controller respectively with the locomotive speed control system, described PLC controller also respectively with front pedal band-type brake switch, the corresponding relay one of locomotive speed control system with the rear treadle corresponding relay two of switch that declutches, be connected, described relay one is connected with the lock positive and negative rotating controller for motor respectively with relay two, the lock positive and negative rotating controller for motor is connected with the lock motor, the lock motor is connected with electric pushrod, current output terminal at described lock motor is connected with DC current transformer, described DC current transformer also is connected with the PLC controller, the red signal capture card is installed on locomotive, described red signal capture card is connected with described locomotive speed control system.
When needs mechanical braking band-type brake, can step on front pedal band-type brake switch, by the PLC controller, make one action of corresponding relay, drive the lock positive and negative rotating controller for motor and control the electric pushrod forward, play the effect of band-type brake, the output speed of frequency converter is zero simultaneously, in the band-type brake process, can control at any time the operating position of lock motor, can control at any time the stroke of electric pushrod.In order to detect lock motor action situation and to guarantee reliable band-type brake, at lock current of electric outgoing side, wear a direct current current transformer, when the lock positive and negative rotating controller for motor has electric current output, DC current transformer induces corresponding signal current, by the PLC programming control, when detecting the lock current of electric over setting value, the action of lock motor automatic stop band-type brake, thus realize reliable band-type brake.When the needs braking is declutched, now step on the rear treadle switch that declutches, by the PLC controller, make two actions of corresponding relay, drive lock positive and negative rotating controller for motor control signal and control the electric pushrod reversion, play the effect of declutching, also can control at any time the stroke of electric pushrod in the process of declutching.
When locomotive operation when the position of red signal is arranged, by the red signal capture card be contained on locomotive, the red light card data received is passed in the locomotive speed control system, call the subprogram of finishing in the locomotive speed control system, be the output speed of frequency converter zero, after five seconds, no matter whether locomotive stops, all pass through the PLC controller, make corresponding relay two, one action, drive lock positive and negative rotating controller for motor control signal and control the electric pushrod forward, play the effect of band-type brake, red eye extinguishes, when greensignal light is bright, call the program of cancelling the restriction of stopping in the locomotive speed control system, locomotive operation personnel just can be according to the speed of the situation manual control machine car of locomotive operation route,
Locomotive general supply dead electricity or other reasons cause electric braking to lose efficacy, and mechanical braking reliable stopping-down still under vehicle-mounted ups drives reaches the two wire system of braking control.
The utility model has the advantages that: what the utility model minimizing human operational error caused runs a red light, with electric locomotive speed, interlock, realize automatic speed-limiting, when outage suddenly, can realize stably stop, reduce the car accident of slipping, when running into sudden stop, and electric braking moves simultaneously, stops fast, control sensitive, easy to operate.
The accompanying drawing explanation
Fig. 1 is workflow block diagram of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of electric locomotive closed loop brake system, include the front pedal band-type brake switch 1 of electric locomotive, the rear treadle switch 2 that declutches, locomotive speed control system 3, lock motor 4, lock positive and negative rotating controller for motor 5 and electric pushrod 6, described front pedal band-type brake switch 1, the rear treadle switch 2 that declutches is connected with PLC controller 7 respectively with locomotive speed control system 3, described PLC controller 7 also respectively with front pedal band-type brake switch 1, the corresponding relay 1 of locomotive speed control system 3 with the rear treadle corresponding relay 29 of switch 2 that declutches, be connected, described relay 1 is connected with lock positive and negative rotating controller for motor 5 respectively with relay 29, lock positive and negative rotating controller for motor 5 is connected with lock motor 4, lock motor 4 is connected with electric pushrod 6, current output terminal at described lock motor 4 is connected with DC current transformer 10, described DC current transformer 10 also is connected with PLC controller 7, red signal capture card 11 is installed on locomotive, described red signal capture card 11 is connected with described locomotive speed control system 3.
