Fig. 2 is a pantograph control circuit schematic diagram of the present utility model.
Embodiment
Below in conjunction with Figure of description the utility model is described in further detail:
See Fig. 1, industrial and mineral electric locomotive emergency exit interlock, this device comprises power supply, hyperbaric chamber, Machine Room door travel switch, fuse, chopper bar is confirmed sound prompt device, the pantograph push-button switch, the pantograph control circuit, the electric control door lock, power supply is connected with hyperbaric chamber, Machine Room door travel switch, hyperbaric chamber, Machine Room door travel switch is connected with fuse, form the chopper bar command signal and deliver to chopper bar affirmation sound prompt device, fuse connects chopper bar simultaneously and confirms sound prompt device and pantograph push-button switch, the pantograph push-button switch connects the pantograph control circuit, and the pantograph control circuit connects the electric control door lock.
See Fig. 2, the pantograph control circuit is to connect pantograph electromagnetically operated valve SV1, SV2, SV3, SV4 respectively by push-button switch 1SA, 2SA, 3SA, 4SA, also connect diode D1, D2, D3, D4 simultaneously respectively, pantograph electromagnetically operated valve SV1, SV2, SV3, the SV4 other end are connected to the GND power supply on the ground, and diode D1, D2, D3, D4 output link together and export to the electric control door lock.
The pantograph of industrial and mineral electric locomotive comprises that two are just being bent and two other bows, and just bend on 1 proper bow, 2 proper bows, 1 end side, 2 ends are other bends, and rises different pantographs in different places, but can only rise a pantograph.
Push-button switch 1SA, 2SA, 3SA, 4SA are respectively that 1 proper bow push-button switch, 2 is rectified bow push-button switches, other push-button switch, the other bow of the 2 ends push-button switches of bending of 1 end, they are on the cab on electric locomotive operating desk, but these 4 push-button switches can not be pressed simultaneously, can only have a push-button switch to press at every turn.Push-button switch 1SA, 2SA, 3SA, 4SA utilize the unilateral conduction of diode respectively by diode D1, D2, D3, D4 simultaneously, and it is electric to guarantee to have only a pantograph electromagnetically operated valve to get, and have only a pantograph action.
Pantograph electromagnetically operated valve SV1, SV2, SV3, SV4 are respectively that 1 proper bow button electromagnetically operated valve, 2 is rectified bow button electromagnetically operated valves, other button electromagnetically operated valve, the other bow of the 2 ends button electromagnetically operated valves of bending of 1 end.After 1 rectified bow push-button switch, 2 and rectifies a push-button switch in bow push-button switches, the other bow of 1 end push-button switch, the other bow of the 2 ends push-button switch and close, corresponding solenoid valve got electric, makes corresponding pantograph action, touches on the electrical network.
The course of work of this device is: comprise the chopper bar state and rise two kinds of processes of arciform attitude.
When the chopper bar state disconnects when pantograph push-button switch on the cab on electric locomotive operating desk, be positioned at the Machine Room simultaneously, the individual travel switch normally-closed contact of hyperbaric chamber door disconnects, behind overcurrent fuse, forming the chopper bar command signal makes chopper bar confirm that sound prompt device carries out voice suggestion, send voice suggestion locomotive driver and conductor and confirm chopper bar, make the corresponding solenoid valve outage, pass through diode simultaneously, make electric control door lock coil blackout remove gate inhibition's signal, automatically open electric control door lock, this moment is by electric-linked Machine Room, electric control door lock interlocking in hyperbaric chamber is opened, and the locomotive driver and conductor can enter the Machine Room, the hyperbaric chamber.
Rising arciform attitude is when the pantograph push-button switch closes on the cab on electric locomotive operating desk, be positioned at the travel switch normally-closed contact closure of Machine Room, hyperbaric chamber door, corresponding solenoid valve is got, simultaneously by diode, make electric control door lock coil get electric after, the iron-core coil action, stretch out, automatically pin Machine Room, hyperbaric chamber door, the electric control door lock is in gate inhibition's state, makes locomotive Machine Room, hyperbaric chamber door be in locking-in state, prevents that the locomotive driver and conductor from entering.
