Description
Technical field
The utility model belongs to bow-lifting device control technology field, particularly relates to a kind of auxiliary lift device for collector bow.
Background technology
In electric locomotive, high ferro and subway, bow-lifting device is used for providing enough compressed air gas sources for vehicle rising bow, ensure when main air source blast needed for rising bow is not enough, air can be supplemented timely and effectively, blast required during to provide pantograph rising bow, make pantograph be connected to high-voltage fence fast, the power that locomotive starts is provided.But there is following several weak point in existing bow-lifting device:
1, the auxiliary rising bow system on current locomotive used can not work alone, and need be controlled the mode of operation of auxiliary air supply unit, increase difficulty and the complexity of locomotive design by microcomputer system on car;
2, current auxiliary air supply unit is when carrying out dry blowback, electromagnetic valve dead electricity, switches to reproduced state by the mode of operation of dryer from drying regime, but often occurs leakage due to electromagnetic valve or block faults such as timing, thus cause auxiliary wind source system to leak gas, therefore can not normal rising bow;
3, the blowback of solenoid control dryer is adopted, taking cost into account not economical and practical.
Summary of the invention
In order to solve the problem, the purpose of this utility model is to provide a kind of more convenient actv. auxiliary lift device for collector bow.
In order to achieve the above object, the auxiliary lift device for collector bow control method that the utility model provides comprises: Air compressor, cooling vessel, dryer, blowback reservoir, safety valve, check valve, reservoir pressure switch and dryer pressure switch;
Wherein: Air compressor is connected with the admission port of dryer by cooling vessel, the air extractor duct of dryer is connected with supplementary reservoir by check valve, blowback reservoir is connected with the back blow port of dryer, safety valve is connected with the air extractor duct of dryer, reservoir pressure switch is connected with supplementary reservoir, and dryer pressure switch is connected with the control mouth of dryer.
Described dryer is tower adsorption dehumifier.
The feature of the auxiliary lift device for collector bow that the utility model provides:
1, the utility model adopts the mode of operation of internal system built-in dryer pressure switch monitoring dryer, and by this signal control contactless coil dead electricity, thus Air compressor is quit work, simple and practical, do not need to carry out logic control by main engine plants, thus reduce the work capacity of locomotive design, raise the efficiency.
2, the utility model carries out control circui by some pressure switches and contactless switch, and relative usage electromagnetic valve cost can carry out actv. control, and effectively can reduce the fault rate of bow-lifting device.
Accompanying drawing explanation
The composition schematic diagram of the auxiliary lift device for collector bow that Fig. 1 provides for the utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the auxiliary lift device for collector bow that the utility model provides is described in detail.
As shown in Figure 1, the auxiliary lift device for collector bow that the utility model provides comprises:
Air compressor U01, cooling vessel U02, dryer U03, blowback reservoir U04, safety valve U05, check valve U06, reservoir pressure switch U07 and dryer pressure switch U08;
Wherein: Air compressor U01 is connected with the admission port of dryer U03 by cooling vessel U02, the air extractor duct of dryer U03 is connected with supplementary reservoir F by check valve (U06), blowback reservoir U04 is connected with the back blow port of dryer U03, safety valve U05 is connected with the air extractor duct of dryer U03, reservoir pressure switch U07 is connected with supplementary reservoir F, and dryer pressure switch U08 is connected with the control mouth of dryer U03.
Described supplementary reservoir F is used for the compressed gas source for rising bow provides.
Described dryer U03 is tower adsorption dehumifier.
The working process of the auxiliary lift device for collector bow that the utility model provides is as follows: air sucks in Air compressor U01 cylinder by air-intake filter, through the crank motion of piston, contract air pressure output squeezing air, the gas compressed through Air compressor U01 enters dryer U03 through subcooler U02 cooling, pressurized air through dryer U03 drying enters blowback reservoir U04, enters supplementary reservoir F by check valve U06 simultaneously; When supplementary reservoir F compressed air reaches dryer U03 setting value, dryer U03 switches to reproduced state, dryer U03 is returned in pressurized air blowback in blowback reservoir U04, the moisture absorbed by desiccant is discharged by the sewage draining exit of dryer U03 to reach desiccant regeneration, reaches the object recycled thus; Meanwhile, dryer U03 exports a pressure makes Air compressor U01 quit work to dryer pressure switch U08, completes a working cycle.When the setting value of the pressure in supplementary reservoir F lower than reservoir pressure switch U07, Air compressor U01 starts, and enters next working cycle.
Pressure in the pipeline caused for preventing fault and reservoir is constantly increased beyond maximum pressure value, and between dryer U03 and check valve UO6, mounting safety valve U05 is used to ensure that gas circuit is no more than safety value.
