Abstract
A separate vibration control device of full hydraulic double steel roller consists of electromagnetic valves, a vibrating pump, vibrating motors, an overflow valve and an oil feed valve; the vibrating pump and two vibrating motors are combined to a series loop; a flushing valve is connected on the series loop consisting of the vibrating pump and two vibrating motors; two electromagnetic valves are respectively connected with the vibrating pump and two vibrating motors; the overflow valve is in parallel connected with the oil feed valve; the overflow valve is connected with the working oilchannel of vibrating motors; the oil feed valve is connected with the vibrating pump. The device enlarges the application scope of double steel roller and can not only achieve the simultaneous vibration of double steel roller but also easily switch to a separate vibrating mode when the small-scope road compaction or the compacting joint requires a monowheel vibration function, thereby improving power utility ratio, saving energy-consumption, reducing the thermal equilibrium temperature of the hydraulic system and improving the reliability of the hydraulic system.
Description
Technical field
The utility model relates to a kind of independent vibration control apparatus of dual-steel wheel road roller.
Background technology
Present all-hydraulic dual-steel wheel road roller does not have independent vibration control apparatus, all control and finish by hydraulic system, the bimotored series connection closed systems of single pump that adopt more, realize reaching the switching of the high short arc of vibrating wheels by positive and negative rotation of motor by electrical equipment two point control plunger displacement pumps, this system only can realize that two-wheel vibrates simultaneously or stops, do not reach ideal effect for the pavement compaction joint part, reduced the scope of application of dual-steel wheel road roller, therefore pressed the road effect low, power consumption is big.
Summary of the invention
The purpose of this utility model provide a kind of energy-saving and cost-reducing, press road effect height, all-hydraulic dual-steel wheel road roller independence vibration control apparatus that the scope of application is wide.
The purpose of this utility model is achieved in that by electromagnetic valve, oscillating column pump, vibrating motor, overflow valve, Fill valve to be formed, oscillating column pump and two vibrating motors are formed series loop, flushing valve is connected oscillating column pump and two vibrating motors are formed in the series loop, two electromagnetic valves are connected with oscillating column pump, two vibrating motors respectively, overflow valve and Fill valve also connect, overflow valve is connected with the vibrating motor working oil path, and Fill valve is connected with oscillating column pump.
Two electromagnetic valves in this device are connected with oscillating column pump, two vibrating motors respectively, realize two switchings that vibrating motor works independently; Overflow valve is connected with the vibrating motor working oil path, controls two vibrating motor operating pressures, plays safety effect; Fill valve is connected with oscillating column pump, runs into when impacting and can in time give system's repairing by slippage pump at vibrating motor; The fluid in the loop is changed in flushing valve when work, play the effect of heat radiation simultaneously.
Because the utility model adopts said structure, enlarge the scope of application of dual-steel wheel road roller, can not only realize that two steel wheels vibrate simultaneously, and when pavement compaction or compacting joint part need the single-wheel vibrating function among a small circle, can easily switch to independent mode of vibration, improve power utilization, saved energy consumption, reduced the thermal equilibrium temperature of hydraulic system and the reliability of raising hydraulic system.
Description of drawings
Fig. 1 is the structure chart of the utility model embodiment.
1 hydraulic oil container, 2 oscillating column pumps, 3 overflow valves, 4 Fill valves, 5 first electromagnetic valves, 6 second electromagnetic valves, 7 flushing valves, 8 first vibrating motors, 9 second vibrating motors among the figure.
The specific embodiment
Embodiment: the oscillating column pump 2 and first vibrating motor 8 and second vibrating motor 9 are formed series loop, flushing valve 7 is connected in the series loop that oscillating column pump 2 and first vibrating motor 8 and second vibrating motor 9 form, first electromagnetic valve 5 is connected with oscillating column pump 2, first vibrating motor 8 and second vibrating motor 9 respectively with second electromagnetic valve 6, overflow valve 3 and Fill valve 4 also connect, overflow valve 3 is connected with second vibrating motor, 9 working oil path with first vibrating motor 8, and Fill valve 4 is connected with oscillating column pump 2.
The slippage pump S mouth of oscillating column pump 2 inside is connected with hydraulic oil container 1, and oil suction is used for the vibration loop from hydraulic oil container 1; Oscillating column pump 2 working hole B link to each other with VB mouth in the independent vibration control apparatus (abbreviation self-contained unit), oscillating column pump 2 working hole A link to each other with VA mouth in the self-contained unit, the M mouth of the slippage pump of oscillating column pump 2 inside links to each other with VH mouth in the self-contained unit, the working hole B of first vibrating motor 8 links to each other with VF mouth in the self-contained unit, the working hole B while of the working hole A of first vibrating motor 8 and second vibrating motor 9 links to each other with the VM mouth in the self-contained unit, the working hole A of second vibrating motor 9 links to each other with VR mouth in the self-contained unit, and the VL mouth in the self-contained unit links to each other with hydraulic oil container 1.
When first electromagnetic valve 5 and second electromagnetic valve 6 were not charged, oil circuit by first electromagnetic valve 5 and second electromagnetic valve 6, do not work simultaneously in the loop at this moment by first vibrating motor 8 and second vibrating motor 9, realizes the function of two-wheel vibration; 5 charged when first electromagnetic valve, when second electromagnetic valve 6 is not charged, first vibrating motor 8 quits work because of two ends working oil path short circuit, at this moment second vibrating motor 9 works independently; Same reason, 6 charged when second electromagnetic valve, when electromagnetic valve a 5 is not charged, second vibrating motor 9 quits work because of two ends working oil path short circuit, and at this moment first vibrating motor 8 works independently.Therefore, first electromagnetic valve 5 and the different charged mode of second electromagnetic valve 6 determine the different vibration modes of vibrating wheels.
