Closeness and the length (particularly length of tunnel) of just present domestic city track, maintenance, the quantity of maintenance engineering vehicle and production time, frequency are all very high, exist a large amount of diesel powerplant coasting time in the car inspection and maintenance operation of the type, vehicle is in dead ship condition in this part time, but because operation needs must allow again diesel powerplant keep power supply, fuel oil consumption is big, and exhaust emission is also many.
The utility model content
Goal of the invention of the present utility model is: at the problem of above-mentioned existence, provide a kind of oil electric mixed dynamic contact system Maintenance and Repair track engineering car, can improve at aspects such as stability, fuel oil consumption, exhaust emissions.
The technical solution adopted in the utility model is such: a kind of oil electric mixed dynamic contact system Maintenance and Repair track engineering car, comprise the engineering truck main body, described engineering truck main body top is provided with the service work platform, detect with pantograph and air-conditioning unit, afterbody arranges hoisting crane, the middle part arranges diesel powerplant, air compressor and air dryer, the front portion arranges traction electric machine, the traction electric machine ventilating set, also comprise by traction invertor and subordinate inverter inverter dimerous, the alternating current of described diesel powerplant output becomes direct current (DC) afterwards in parallel with a traction accumulator group through a rectifier rectification, link to each other with traction electric machine by traction invertor then, by subordinate inverter and traction electric machine ventilating set, air compressor, the air-conditioning unit links to each other.
As preferably, described rectifier, traction accumulator group and inverter all are arranged in the engineering truck main body middle part.
As preferably, also is provided with storage battery cooling blower and car body blower fan by the described traction accumulator group, this storage battery cooling blower also links to each other with subordinate inverter respectively with the car body blower fan.
As preferably, described subordinate inverter also respectively with the service work platform, detect and link to each other with pantograph, air dryer and hoisting crane.
In sum, owing to adopted technique scheme, the beneficial effects of the utility model are: adopted the oil electric mixed dynamic technology, the stability of car load is improved; In the time period of diesel engine running down, the work electricity consumption is provided by the traction accumulator group, has effectively reduced fuel oil consumption and the exhaust emission of vehicle, and the noise pollution problem also improves.
