Description
Technical field
The invention belongs to road construction work field of mechanical technique, be specifically related to a kind of hydraulic vibration press-roller device of directed road roller.
Background technology
The road roller of road construction work machinery is mainly the deadweight that utilizes road roller, by pressure roller, by pavement compaction, improves service life of road surface.Worldwide road roller has experienced first generation road roller-light roller road roller, second generation road roller-compound road roller (light roller and the combination of glue roller), the third generation and has pressed this three phases of road-mechanical oscillation road roller.Compound road roller has overcome the shortcoming that smooth roll road roller road pavement salient point can not compacting around, thereby increased the compaction rate on whole road surface, vibratory roller is to utilize impact force acting, thereby greatly improved the normal pressure of pressure roller road pavement, made the compaction rate on road surface obtain further raising.Yet vibratory roller is the circular motion by eccentric month block teeth produces vibration force, and its power all produces power to sextuple space, but only downward power just can be done useful work, thereby this mode of vibration available power is low, and vibration frequency is also low.The vibration frequency of vibratory roller is the important parameter that material granule motion state is pressed in impact, under certain condition, change vibration frequency, pressed the degree of compaction of material to change thereupon, under high vibration frequency effect, pressed the acceleration of motion of material granule to increase, interior frictional resistance sharply declines, intergranular mutual filling effect is strengthened, and consolidation effect is good.The vibration frequency of existing vibratory roller is in 20-100Hz left and right, and vibration frequency is difficult to significantly improve.As straight line, move back and forth at a high speed and realize road roller pressure roller vibration prior art and also do not have, but straight line moves back and forth at a high speed the problem lubricated and sealing that exists.If in the larger situation of linear velocity, its seal form is clearance seal, the large lubricating fluid leakage problem that exists in clearance seal gap, gap is little, and lubricant effect is bad, easily produces metal semi-dry friction or dry friction, calorific value is large, easily expands stuck, and lubricated middle solid particle enters also easily stuck.The pressure roller weight of road roller is heavier, and deflection easily appears in the fairlead of existing reciprocating rod member, makes during rod member can not determine, to cause driving the easy flexural deformation of rod member of pressure roller, cannot normally work.
Summary of the invention
The above-mentioned defect existing for solving prior art, the object of the present invention is to provide a kind of compact conformation, and volume is little, cost is low, vibration force is relatively concentrated on and exerted oneself, and vibration frequency is continuously adjustable and can reach upper frequency, the directional vibration road roller that available power is high.
For achieving the above object, the technical solution used in the present invention: this directional vibration road roller, there is pressure roller and the hydraulic vibration device being connected with pressure roller, it is characterized in that: described hydraulic vibration device forms by vibrating oil cylinder, oil cylinder control device for reversing and Hydraulic Station, Hydraulic Station is connected with oil cylinder control device for reversing, and oil cylinder control device for reversing is connected and controls commutation with vibration oil cylinder; The moving oily output of described Hydraulic Station consists of hydraulic oil container, oil filter, pump motor group, one way valve, manual two position three-way valve and adjustable throttling successively, and each parts connect by oil pipe, and described one way valve outlet is provided with pilot operated compound relief valve; Described oil cylinder control device for reversing is zero lap two-position four-way valve, and the valve body two ends of described zero lap two-position four-way valve are provided with feedback oil groove, in feedback oil groove, is provided with rapid reversal valve core; The in-oil cylinder piston of described vibration two ends are provided with supercharging boss, and cylinder block is provided with the supercharging groove adapting with supercharging boss, and supercharging groove is connected with described feedback oil groove by oil pipe; The piston rod of described vibration oil cylinder connects pressure roller, and the piston rod of vibration oil cylinder is combined with fairlead.
