Abstract
The utility model discloses a safety interlocking device for refueling vehicle in airport, comprising an air braking interlocking device, one end of the air storing cylinder of the braking interlocking device is connected with the inlet of a clutch power controlling valve via rubber tube passing through a safety valve, the other end of the air storing cylinder is connected with the inlet of the clutch power controlling valve via rubber tube passing through a two-position three-way controlling valve, the two-position three-way air controlling valve is connected with one end of the tee through rubber tube, another end of the tee is connected with the outlet of a final braking interlocking valve of the wheel braking system, the other end of the tee is connected with an overrunning braking interlocking valve. The utility model has advantages of simple structure, being safe and reliable, and low technical transformation cost.
Description
Utility model relates to the braking inter locking gear, belongs to a kind of aircraft gas refueller safety interlock.
At present, CGJ5270GJYST type aircraft gas refueller adopts " Steyr 91 series " car chassis to convert.What the safe-guard system of this car refueling process adopted is gas control braking inter locking gear, and promptly when filling car was implemented refueling operation, the pressurized air of braking locking system was bled off, and wheel is in braking mode and can't travels.But should the design of braking inter locking gear have deficiency, when the chain inefficacy of braking, filling car is in operating condition, and vehicle still can be started to walk and travel; Though brake chain working, can not be with wheel lockup, vehicle still can start to walk to travel during driver's open the throttle wide, and causes drawing the flying coffin oiling to connect the generation of mouth accident.Development along with the civil aviation cause, aircraft in unit time landing number of times continues to increase, sortie that fuels a plane and delivery quality also strengthen thereupon, and the possibility of drawing the flying coffin oiling to connect the generation of mouth accident is also strengthening, and bring serious future trouble for " CAAC fuel " safety in production.
The purpose of this utility model provides a kind ofly can fundamentally stop the generation that filling car draws flying coffin to refuel to connect the mouth accident, simple in structure, safe and reliable aircraft gas refueller safety interlock.
The purpose of this utility model is to realize like this, comprise gas control braking inter locking gear, air receiver one end of its braking inter locking gear is joined through safety valve and clutch power-assisted control cock import by India rubber tube, the air receiver other end is joined through two-position three way Pneumatic valve and clutch power-assisted control cock import by India rubber tube, the two-position three way Pneumatic valve is joined by India rubber tube and threeway one end, the final braking interlocking valve outlet of the another end of threeway and wheel brake system is joined, the other end of threeway by India rubber tube with surmount the braking interlocking valve and join.
The improvement of the utility model on the gas control inter locking gear; also lock-up clutch when making refueling operation and brake wheel; play the dual security protection effect; connect mouth and do not take off as long as refuel on the aircraft; vehicle just can not be started to walk certainly, has fundamentally stopped to draw the flying coffin oiling to connect the generation of mouth accident.Because this apparatus structure is simple, the technological transformation cost is low, and is safe and reliable, applicable to the airport pot type filling car of similar fuel loading system.
Below in conjunction with drawings and Examples the technical solution of the utility model is described.
Fig. 1 is the structural representation of the utility model embodiment
What the filling car power-transfer clutch adopted is the air pressure assisted steering unit of mechanical drive, and clutch control valve is opened when the chaufeur let slip the clutch, and power-transfer clutch could normal operation under the effect of air pressure.Gas control braking inter locking gear is the final braking interlocking valve that comprises air receiver, clutch power-assisted control cock, wheel brake system, surmount braking interlocking valve or the like parts is prior art.Referring to Fig. 1, air receiver 5 one ends of braking inter locking gear at gas control are joined through safety valve 6 and clutch power-assisted control cock 7 imports by India rubber tube, and air receiver 5 other ends are joined through two-position three way Pneumatic valve 4 and clutch power-assisted control cock 7 imports by India rubber tube; Two-position three way Pneumatic valve 4 other ends are joined by India rubber tube and threeway 2 one ends, and threeway 2 another ends are joined by final braking interlocking valve 1 outlet of India rubber tube and wheel brake system, threeway 2 other ends by India rubber tube with surmount braking interlocking valve 3 and join.The internal diameter of used India rubber tube is 5mm between two-position three way Pneumatic valve 4 and the threeway 2, and rated insulation voltage is 8Kg.Safety valve 6 must carry out lead sealing, and safety valve 6 is a hand valve.Working process: it is that pneumatic control system is passed through the logic gas circuit that filling car is finished five kinds of operations; make oil pump systems finish various normal operations; braking chain simultaneously also is to change the chain spool position of braking under air operated control; cut off source of the gas; wheel braking (principle of energy storage type brake); chain lamp is bright; the clutch mechanism transmission gas control system of assisteding control dies; power-transfer clutch is in " locked " state; power-transfer clutch can't be worked; vehicle is hung and is not performed, and reaches the purpose that vehicle can not start to walk to travel, and plays the effect of dual security protection.After refueling process finishes, as long as the oiling personnel connect mouth with oiling and take off from aircraft, and be placed on the machine control valve, brake chain effect and remove, at this moment, clutch power-assisted control cock also obtains pressurized air, and power-transfer clutch recovers normal working again.If improved clutch control gas circuit et out of order can be opened safety valve 6, but vehicle cruising.
