Abstract
The utility model belongs to the technical field of railroad engineering work vehicle air compressor driving, particularly relates to an air compressor driving system, and overcomes defects in an existing railroad engineering work vehicle air compressor driving mode. The air compressor driving system comprises a hydraulic oil tank, an oil suction pump and a hydraulic motor connected with an air compressor through an elastic coupling, wherein the hydraulic oil tank, the oil suction pump and the hydraulic motor are sequentially connected, the hydraulic motor is in parallel connection with an electromagnetic relief valve, and the hydraulic motor and the electromagnetic relief valve are further connected with the hydraulic oil tank. The air compressor driving system has the advantages that operation of the air compressor can be effectively driven, stopping and operating of the air compressor can be controlled according to pressure of a main air reservoir, and power waste is avoided. Compared with an air compressor driven by a motor, the system is low in manufacturing cost, easy to install, and especially easy to achieve on a railroad engineering work vehicle. Compared with belt transmission, the system is stable, high in transmission efficiency, and easy to maintain, and greatly reduces work intensity of construction staff.
Description
Technical field
The utility model belongs to the technical field that railway engineering operating vehicle air compressor drives, and is specifically related to a kind of air compressor drive system.
Background technique
The used braking of track vehicle is air damping, and air compressor then provides the key equipment of wind regime on the car, so whether the working state of air compressor well is directly connected to the Safety performance of car load.Except the performance of air compressor itself, its driving mode also is very important factor.At present, used air compressor driving mode mainly contains two kinds on the track vehicle:
1, by the moving air compressor running of motor straight tape splicing, this driving mode can be air compressor stable rotating speed is provided, and working stability is beaten wind efficient height.But this mode need to provide the motor of relatively high power, and for machine operation provides sufficient power supply, this mode is used more general at electric locomotive, internal combustion locomotive.And as the Engineering vehicle, implement comparatively difficulty, and cost is very high.
2, by the bel-drivenn mode, drive the air compressor running by engine belt pulley by belt.This driving mode simple installation is to use the most general a kind of driving mode on the Engineering vehicle.But because belt can heating after work a period of time, the phenomenon such as occur easily skidding, thus greatly reduce transmission efficiency, and also need often to adjust in use the elasticity of belt.
Summary of the invention
Goal of the invention of the present utility model: solve the deficiency that existing railway engineering operating vehicle air compressor driving mode exists, the driving air compressor that realization can be efficient, safe.
The utility model adopts following technological scheme to realize: the air compressor drive system, it is characterized in that comprising hydraulic oil container, oil scavenge pump and the oil hydraulic motor that is connected by elastic coupling flexible coupling with air compressor, hydraulic oil container, oil scavenge pump are connected with oil hydraulic motor and are connected, oil hydraulic motor is parallel with electromagnetic relief valve, and oil hydraulic motor is connected with electromagnetic relief valve and is connected with hydraulic oil container.
The beneficial effects of the utility model: can effectively drive air compressor running, and can according to total reservoir pressure control stopping and turning of air compressor, avoided the waste of power.Compare than the motor drive mode air compressor, this system cost is low, installs simply particularly and realizes easily on the railway engineering vehicle.Compare than belt transmission, this system stability, transmission efficiency height are safeguarded simply, greatly reduce workmen's working strength.
Description of drawings
Fig. 1 is structural representation of the present utility model
Among the figure: 1-oil scavenge pump, 2-oil hydraulic motor, 3-elastic coupling flexible coupling, 4-air compressor, 5-electromagnetic relief valve, 6-pressure transducer, 7-operating console, 8-hydraulic oil container, 9-main air-duct.
Embodiment
As shown in Figure 1, the air compressor drive system, comprise hydraulic oil container 8, oil scavenge pump 1 and the oil hydraulic motor 2 that is connected by elastic coupling flexible coupling 3 with air compressor 4, hydraulic oil container 8, oil scavenge pump 1 are connected with oil hydraulic motor successively and are connected, oil hydraulic motor 2 is parallel with electromagnetic relief valve 5, and oil hydraulic motor 2 is connected with electromagnetic relief valve and is connected with hydraulic oil container 8.
The utility model is to provide power source by motor, and through a cover hydrostatic drive system, motor connects with air compressor by elastic coupling flexible coupling, thereby drives the air compressor running.Oil scavenge pump 1 is from hydraulic oil container 8 oil suctions, and then actuator oil hydraulic motor 2 moves, and oil hydraulic motor 2 connects with air compressor 4 by part elastic coupling flexible coupling 3, thereby drives the air compressor running, and hydraulic oil is through the return line oil sump tank.In this cover hydrostatic pressure system, electromagnetic relief valve 5 is set.
Relief valve is off-load in both cases: a kind of for commonly used when surpassing the setting pressure of relief valve itself, another kind then is when total reservoir pressure reaches 8 kilograms/cm2, by part pressure transducer 6, total reservoir pressure signal is converted to electrical signal, then control electromagnetic relief valve action off-load, can avoid the loss of power.
