Description
Technical field
The utility model relates to the rail locomotive brake system, refers to that especially the under-voltage train pipe in a kind of blast main road cuts off the air draft control setup automatically.
Background technology
The rail locomotive brake system is the critical component that guarantees track traffic safety, and the safety of brake system, reliability and stability are particularly important.Therefore brake system exists hidden danger constitute a serious threat for the application safety of locomotive.
Locomotive braking system is passed by general traction blockade and emergency braking or the parking brake implemented of low pressure protection to blast main at present.And in practice, not enough below existing: 1, existing locomotive blast main is passed by the low pressure protection train pipe air draft control setup is not set, and just implements corresponding braking safety method through the locomotive circuit logic control element; 2, when locomotive blast main hypotony, the electric component of locomotive circuit logic control element lost efficacy or the situation of fault under, locomotive braking system can not in time implement to brake accordingly safety method, brings great potential safety hazard for the normal operation of locomotive; When 3, locomotive used under heavy gang mould formula, multi-locomotive was not isolated the train pipe on gas circuit.
Summary of the invention
The utility model technical matters to be solved is; Not enough to prior art; Provide the under-voltage train pipe in a kind of blast main road to cut off the air draft control setup automatically; Also can isolate train pipe and air draft automatically when making inefficacy of brake system electric component or fault, thereby the safety and stability that guarantees locomotive braking system is reliable.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of blast main road is under-voltage, and the train pipe cuts off the air draft control setup automatically, comprises pneumatic valve and electromagnetic valve; The pneumatic valve left and right sides is provided with valve port; The valve port in pneumatic valve left side links to each other with the outlet of equalizing reservoir of motor vehicle relay valve train pipe, and the valve port on pneumatic valve right side links to each other with the import of locomotive distributing valve train pipe, and a side of pneumatic valve is provided with exhaust outlet; Link to each other with atmosphere, the pneumatic valve bottom is provided with and makes valve port; Electromagnetic valve is provided with admission port, air extractor duct and exhausr port, and the admission port at electromagnetic valve top links to each other with the locomotive blast main, and air extractor duct links to each other with making valve port, and admission port links to each other with air extractor duct, exhausr port and atmosphere; Electromagnetic valve is connected with the interior brak control unit of locomotive.Said pneumatic valve bottom is provided with micro-switch, and micro-switch is connected with brak control unit.
The utility model gets electric through control electromagnetic valve and dead electricity realizes that the connected sum of gas circuit between blast main road and pneumatic valve blocks; During the electromagnetic valve dead electricity; Air between emptying pneumatic valve and electromagnetic valve, the connected sum on pneumatic valve and blast main road blocks, or blast main road hypotony; Can make the pneumatic valve action, thereby isolate from the connected sum of gas circuit control train pipe.
Compared with prior art, the advantage of the utility model is: this device can be controlled the connection of train pipe, isolate and air draft automatically through the dead electricity that gets of electrically-controlled valve; The blast main hypotony that is communicated with pneumatic valve also can realize blocking of train pipe and air draft automatically from gas circuit.

Wherein:
1: pneumatic valve; 2,3: valve port; 4: exhaust outlet; 5: micro-switch; 6: make valve port; 7: electromagnetic valve; 8: air extractor duct; 9: admission port; 10: exhausr port; 11: brak control unit; 12: the train pipe; 13: blast main.
The specific embodiment
As shown in Figure 1; A kind of blast main road is under-voltage, and the train pipe cuts off the air draft control setup automatically; Comprise pneumatic valve 1, pneumatic valve 1 bottom is provided with the micro-switch 5 of monitoring pneumatic valve state, and said pneumatic valve 1 both sides are provided with valve port 2,3; Valve port 2 links to each other with 12 outlets of equalizing reservoir of motor vehicle relay valve train pipe, and valve port 3 links to each other with 12 imports of locomotive distributing valve train pipe; These pneumatic valve 1 one sides also are provided with exhaust outlet 4, itself and atmosphere.
When electromagnetic valve 7 was in power failure state, admission port 9, air extractor duct 8 and make valve port 6 keep being communicated with were crossed when low when total wind pressure, can make pneumatic valve 1 action; Or when locomotive is in heavy gang mould formula, brak control unit 11 let electromagnetic valve 7 electronic work, air extractor duct 8 is communicated with exhausr port 10, emptying air extractor duct 8 and the air pressure that makes 6 of valve ports are moved pneumatic valve 1.
During pneumatic valve 1 action, valve port 3 is communicated with exhaust outlet 4, blocks the equalizing reservoir relay valve and fills the path of wind to train pipe 12, and make 12 decompressions of train pipe keep braking mode or produce braking; Pneumatic valve 1 bottom is provided with micro-switch 5, can in time monitor pneumatic valve action state, gives brak control unit 11 with feedback of status.
The blast main road is under-voltage, and the train pipe cuts off the air draft control method automatically is:
1) when locomotive dead electricity and brak control unit not during control electromagnetic valve, electromagnetic valve is in power failure state, and the valve port that makes of electromagnetic valve admission port, air extractor duct and pneumatic valve keeps being communicated with, when total wind pressure is crossed when low the pneumatic valve action; When locomotive was in heavy gang mould formula, the brak control unit control electromagnetic valve got electronic work, and the electromagnetic valve air extractor duct is communicated with the electromagnetic valve exhausr port, and emptying solenoid valve air extractor duct and make the air pressure between valve port moves pneumatic valve;
When 2) pneumatic valve moves; Valve port is communicated with the pneumatic valve exhaust outlet; Block the locomotive relay valve fills wind to the train pipe path; And making the decompression of train pipe keep braking mode or generation braking, the operating state of the micro-switch monitoring pneumatic valve of pneumatic valve bottom feeds back to brak control unit with status information.
