Technical field
The utility model relates to a kind of road roller hydraulic system, specifically is a kind of double-steel wheeled vibratory roller front and back wheel branch hydraulic system of shaking, and belongs to the hydraulic system field of road roller steel wheeled vibratory.
Background technology
Double-steel wheeled vibratory roller is the indispensable machinery of road construction work, and is more smooth than the compacting of single-drum road roller road pavement, and the compacting on roadbed and road surface is played an important role; Traditional double-steel wheeled vibratory roller is that front and back wheel is vibrated simultaneously; Though it is relatively good that front and back wheel is vibrated the compacting effect of road pavement simultaneously, when repairing for repair the roads last time compacting and short less highway section, the operating mode that front and back wheel is vibrated simultaneously just is restricted; In addition; Compacting for last time of repairing the roads does not need too big exciting force, and exciting force is excessive then can to cause adverse influence to the road surface that approaches completion, and a leveling also need be carried out in the road surface that often causes tamping completion; Cause spinning out of operation, wasted the time, the man power and material.
Summary of the invention
Problem to above-mentioned prior art existence; The utility model provides a kind of double-steel wheeled vibratory roller front and back wheel branch hydraulic system of shaking; Through the single steel wheeled vibratory of HYDRAULIC CONTROL SYSTEM realization double-steel wheeled vibratory roller, the effect of the quiet stone roller leveling of another steel wheel has reduced operation; Save great amount of time, man power and material, improved operating efficiency effectively.
To achieve these goals; The utility model is realized through following technical scheme: a kind of double-steel wheeled vibratory roller front and back wheel branch hydraulic system of shaking; Involving vibrations pump, vibration electromagnetic valve and vibrating motor; The high pressure hydraulic fluid port A of oscillating column pump, B are connected with high pressure hydraulic fluid port C, the D of vibration electromagnetic valve respectively; The high pressure hydraulic fluid port C1 of vibration electromagnetic valve is connected with the high pressure hydraulic fluid port F1 of vibrating motor, and the high pressure hydraulic fluid port D1 of vibration electromagnetic valve is connected with the high pressure hydraulic fluid port E2 of vibrating motor, and the high pressure hydraulic fluid port P of vibration electromagnetic valve is connected with high pressure hydraulic fluid port E1, the F2 of vibrating motor respectively.
Oscillating column pump is a shaft orientation plunger variable pump.
The vibration electromagnetic valve comprises two three position four-way electromagnetic valves, is made up of solenoid operated directional valve, high-pressure overflow valve and flushing valve.
Vibrating motor has two, is the axial plunger fixed displacement motor.
The beneficial effect of the utility model is: system's components and parts are few, compact conformation, and control is simple; With low cost, be convenient to investigate fault and plant maintenance, reduced flow chart; Great amount of time, man power and material have been saved; Improve operating efficiency effectively, enlarged the scope of application of double-steel wheeled vibratory roller, be applicable to various road conditions.
Description of drawings
Fig. 1 is the hydraulic control theory diagram of the utility model.
Among the figure: 1, oscillating column pump, 2, the vibration electromagnetic valve, 3, vibrating motor.
The specific embodiment
To combine accompanying drawing that the utility model is further specified below.
As shown in Figure 1; A kind of double-steel wheeled vibratory roller front and back wheel branch hydraulic system of shaking; Involving vibrations pump 1, vibration electromagnetic valve 2 and vibrating motor 3; The high pressure hydraulic fluid port A of oscillating column pump 1, B are connected with high pressure hydraulic fluid port C, the D of vibration electromagnetic valve 2 respectively; The high pressure hydraulic fluid port C1 of vibration electromagnetic valve 2 is connected with the high pressure hydraulic fluid port F1 of vibrating motor 3, and the high pressure hydraulic fluid port D1 of vibration electromagnetic valve 2 is connected with the high pressure hydraulic fluid port E2 of vibrating motor 3, and the high pressure hydraulic fluid port P of vibration electromagnetic valve 2 is connected with high pressure hydraulic fluid port E1, the F2 of vibrating motor 3 respectively.
Oscillating column pump 1 is a shaft orientation plunger variable pump.
Vibration electromagnetic valve 2 comprises two three position four-way electromagnetic valves, is made up of solenoid operated directional valve, high-pressure overflow valve and flushing valve.
Vibrating motor 3 has two, is the axial plunger fixed displacement motor.
The course of work of the utility model is: motor passes to oscillating column pump 1 with mechanical energy, and oscillating column pump 1 is converted into hydraulic pressure with mechanical energy can pass to vibration electromagnetic valve 2 and vibrating motor 3 with energy through hydraulic oil; Vibration electromagnetic valve 2 is two point control; Two vibrating motors 3 are installed on the front-wheel and the trailing wheel of road roller respectively.
Under the prerequisite of oscillating column pump 1 work, it is electric that a position that vibrates electromagnetic valve 2 is got, and just cut off the oil circuit of trailing wheel, realizes the independent vibration of front-wheel; When vibrating electromagnetic valve 2 at meta, front and back wheel is vibrated simultaneously; It is electric that the b position that vibrates electromagnetic valve 2 is got, and just cut off the oil circuit of front-wheel, realizes the independent vibration of trailing wheel.It is the control electromagnetic valve realization by oscillating column pump that the height of vibrating wheels 8 amplitudes shakes.
