Abstract
The utility model provides a hydraulic driving device of an air compressor, which comprises a hydraulic motor, a driving shaft of which is connected with a main shaft of an air compressor, and is characterized in that an oil inlet of the hydraulic motor is connected with an oil inlet pipe, the oil inlet pipe is sequentially provided with a solenoid directional valve, a check valve and a hydraulic pump, wherein the oil inlet end of the oil inlet pipe is connected with an oil tank, an oil outlet of the hydraulic motor is connected with an oil outlet pipe, and after being connected with the same solenoid directional valve on the oil inlet pipe, the oil outlet pipe is connected with the oil tank. The traditional air compressor driven by a motor is changed to be driven by the hydraulic motor, therefore, only a vehicle-mounted 24V direct-current power supply for a special vehicle for railway maintenance machines needs to be used to cause the whole hydraulic motor system to start working, so as to drive an air brake system to brake the special vehicle for the railway maintenance machines, more electric power is not needed any more, not only vehicle-mounted diesel amount is reduced, and the operation load of the whole vehicle is reduced, but also fuel is saved, cost is reduced, and railway maintenance is facilitated.
Description
Technical field
The utility model relates to a kind of drive unit, and particularly a kind of fluid pressure drive device that drives air compressor belongs to design of air compressor drive unit and manufacturing technology field.
Background technique
Railway maintenance machinery is the special-purpose vehicle of maintenance railway, and what the braking system on it adopted is air braking system.Because air braking system need drive by cleaning dry pressure air, pressure air is produced by the air compressor unit again.Because existing air compressor unit is all driven by AC motor, and large-scale maintenance machinery equipment is the self-operating vehicle, by Diesel Driven, only be loaded with the 24V DC electrical source of finite energy on the car, the ac power supply of no 220V, need the optional equipment Vehicular electric generator to drive air compressor work for this reason, and existing Vehicular electric generator adopts diesel generator substantially, so just need be equipped with enough diesel oil onboard and just can be used for driving power system and power generation system, increased the operating load of railway maintenance vehicle greatly, make troubles to railroad maintenance, and increase cost.Therefore be necessary prior art is improved.
Summary of the invention
Excessive for solving the air braking system that has railway maintenance machinery now because of the diesel oil amount of carrying that adopts electric drive to bring, railway maintenance vehicle operating load is overweight, railroad maintenance inconvenience, problems such as cost height, the utility model provides a kind of air compressor fluid pressure drive device.
What its technical problem that solves the utility model adopted is a kind of like this air compressor fluid pressure drive device, it comprises the oil hydraulic motor that its live axle is connected with the air compressor main shaft, it is characterized in that the oil hydraulic motor filler opening links to each other with oil inlet pipe, be provided with solenoid directional control valve on the oil inlet pipe successively, one-way valve, oil hydraulic pump, the oil inlet pipe oil inlet end links to each other with fuel tank, the oil hydraulic motor oil outlet links to each other with oil outlet tube, oil outlet tube is with after same solenoid directional control valve on the oil inlet pipe links to each other, link to each other with fuel tank, send into oil inlet pipe so that hydraulic oil is extracted out from fuel tank by oil hydraulic pump, send in the oil hydraulic motor through one-way valve and solenoid directional control valve, send into oil outlet tube again, get back in the fuel tank through solenoid directional control valve, finishing driving, thereby make the work of fluid motor-driven air compressor oil hydraulic motor.
Oil inlet pipe between described oil hydraulic pump and the fuel tank is provided with filter, so that hydraulic oil is filtered.
Oil inlet pipe between described oil hydraulic motor filler opening and the solenoid directional control valve is provided with flow control valve, so that control the flow of hydraulic oil by flow control valve.
Be connected an other pipe of overflow of establishing relief valve on it between the oil outlet tube between oil inlet pipe between described one-way valve and the oil hydraulic pump and solenoid directional control valve and the fuel tank, with convenient oil inlet pipe internal pressure when excessive, open relief valve and make the pressure oil in the oil inlet pipe drain into fuel tank, to guarantee safety through the other pipe of overflow.
Described flow control valve, solenoid directional control valve and oil hydraulic pump all are connected with external power supply by lead, so that they are controlled.
The utlity model has following advantage and effect: adopt such scheme, with traditional motor-driven air compressor of using, change into oil hydraulic motor and driving, so only need to use the vehicle-mounted 24V DC electrical source on the railway maintenance machinery special-purpose vehicle, whole hydraulic motor system is started working, thereby the driving air braking system is finished the braking to railway maintenance machinery special-purpose vehicle, no longer need more electric power, not only reduced vehicle-mounted diesel oil amount, reduced the running load of car load, fuel saving reduces cost simultaneously, makes things convenient for railroad maintenance.Be a desirable air compressor drive unit in fact.
