Compared with prior art, the beneficial effect that the utility model had is: the utility model is informed driver's vehicle braked or relieved state by braking/alleviation indicator lamp on the one hand, make the driver can accurately judge the braking or the relieved state of vehicle parking brake equipment, alleviate indicatrix on the other hand and brake indicatrix and be linked into simultaneously in the traction control unit of locomotive, by the interlocking judgement correct with the locomotive traction control unit, solve the defective that the network transmission is interrupted, improved rolling stock reliability of operation and safety.Particularly:
1, the spring energy-storage stopping brake to vehicle adopts hard lead control, avoids network transmission interruption or microcomputer to crash and causes stop device control mistake, has improved serviceability;
2, the brake-pressure switch on the truck spring accumulation of energy stop device (connecing normally closed point) parallel connection, the switch of releasing the pressure (connecing normal battle) series connection can be judged brake equipment braking or relieved state accurately;
3, the status signal of stop device is connected with the locomotive traction control unit, provides braking or the relieved state of traction control unit to locomotive to judge soundly, and takes appropriate measures, and has guaranteed the safety in operation of rolling stock.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
As shown in Figure 1, the utility model comprises the power supply that is connected in locomotive 12 and runs through the braking instruction line 1 of each vehicle 13, alleviation order line 2, braking indicatrix 3, alleviation indicatrix 4 and zero line 5, and this braking instruction line 1, alleviation order line 2, braking indicatrix 3, alleviation indicatrix 4 and zero line 5 all are hard leads.Be connected with between alleviation order line 2 on each joint vehicle and the zero line 5 and can charge into compressed-air actuated alleviation electropneumatic valve 6 by the controlling spring loaded brake cylinder, be connected with the braking electropneumatic valve 7 of the pressurized air exhaust to atmosphere of energy controlling spring loaded brake cylinder between braking instruction line 1 and the zero line 5, being connected with operating value between this braking indicatrix 3 and the zero line 5 is the closed type brake-pressure switch 8 of low pressure, alleviates that operating value also is installed on the indicatrix 4 is the high-voltage open type switch 9 of releasing the pressure.Be positioned at braking indicator lamp 10 also is installed on the braking indicatrix 3 of locomotive, alleviate also to be equipped with on the indicatrix 4 and alleviate indicator lamp 11.This brake-pressure switch 8 and the switch 9 of releasing the pressure all are pressure operated switchs.This brake-pressure switch 8 is whether the indication parking brake takes place; The switch 9 of releasing the pressure is whether the indication parking brake is alleviated fully.When multi-section vehicles linked, brake-pressure switch 8 was designed to parallel connection, and the switch 9 of releasing the pressure is designed to series connection; If brake-pressure switch 8 closures on the joint vehicle are arranged, the indicator lamp on the braking indicatrix 1 promptly lights, and expression car team parking brake applies; Have only switch 9 closures of releasing the pressure on all vehicles, the indicator lamp of alleviating on the indicatrix 4 just lights, and the expression car team is parked alleviation.On the minor details vehicle, also need the alleviation indicatrix 4 and the zero line 5 of tail end are joined, make and alleviate indicatrix 4 formation loops.
When the utility model used, when the driver sent braking instruction, braking instruction line 1 was high level output, and the braking electropneumatic valve 7 on the vehicle 13 gets electric, the pressurized air exhaust to atmosphere of spring-loaded brake cylinder, and vehicle 13 parking brakes apply; And be contained in normally closed brake-pressure switch 8 closures on the vehicle 13 (because the compressed air pressure of braking front spring loaded brake cylinder is greater than the operating pressure of brake-pressure switch 8, thereby before the braking, the brake-pressure switch is open), the braking indicator lamp 10 on the braking indicatrix 3 lights.When the driver sent the alleviation instruction, alleviating order line 2 was high level output, and the alleviation electropneumatic valve 6 on the vehicle 13 gets electric, and spring-loaded brake cylinder charges into pressurized air, the alleviation of vehicle 13 parking brakes; And be contained in open type on the vehicle 13 switch 9 closures of releasing the pressure, the alleviation indicator lamp of alleviating on the indicatrix 4 11 lights.
This braking indicatrix 3 and alleviation indicatrix 4 are linked in the traction control unit 14 of locomotive simultaneously, this traction control unit 14 is by the internal logic computing, alleviate indicatrix 4 disconnections (promptly alleviating indicatrix 4 is low level output) when detecting, then traction control unit 14 is with automatic removal tractive force; In operational process (be speed greater than zero), if detect braking indicatrix 3 closures, then traction control unit 14 is automatic removal tractive force, and punishes braking.
