Description
Technical field
The invention belongs to the 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 mainly is the deadweight that utilizes road roller, with pavement compaction, improves service life of road surface through pressure roller.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 road-this three phases of mechanical oscillation road roller.Compound road roller overcome around the smooth roll road roller road pavement salient point can not compacting shortcoming; Thereby increased the compaction rate on whole road surface; Vibratory roller then is to utilize the impact force acting; Thereby improved the normal pressure of pressure roller road pavement greatly, made the compaction rate on road surface obtain further raising.Yet vibratory roller is to lean on the circular motion of eccentric month block teeth to produce 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 the material granule motion state is pressed in influence,, changes vibration frequency under certain condition; 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 descends; Intergranular mutual filling effect is strengthened, and consolidation effect is good.The vibration frequency of existing vibratory roller is about 20-100Hz, and vibration frequency is difficult to significantly improve.Moving back and forth realization road roller pressure roller vibration prior art at a high speed as straight line does not also have, but straight line moves back and forth the problem lubricated and sealing that exists at a high speed.Under the bigger situation of linear velocity, its seal form is a clearance seal, the big lubricating fluid leakage problem that exists in clearance seal gap; The gap is little, and lubricant effect is bad, is prone to produce metal semi-dry friction or dry friction; Calorific value is big, and it is stuck to be prone to expand, and lubricated middle solid particle entering also is prone to stuck.The pressure roller weight of road roller is heavier, and deflection appears in the fairlead of existing reciprocating rod member easily, makes during rod member can not decide, and causes driving the easy flexural deformation of rod member of pressure roller, can't operate as normal.
Summary of the invention
For solving the above-mentioned defective that prior art exists, the object of the present invention is to provide a kind of compact conformation, volume is little; Cost is low; Concentrate on vibration force relatively and to exert oneself, vibration frequency is adjustable continuously and can reach upper frequency, the directional vibration road roller that available power is high.
For realizing above-mentioned purpose; The technical scheme that the present invention adopts: this directional vibration road roller; Have pressure roller and the hydraulic vibration device that is connected with pressure roller; It is characterized in that: said hydraulic vibration device is made up of vibration oil cylinder, oil cylinder control device for reversing and Hydraulic Station, and Hydraulic Station is connected with the oil cylinder control device for reversing, and the oil cylinder control device for reversing is connected the control switching-over with the vibration oil cylinder; The moving oily output of said Hydraulic Station is made up 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 connects through oil pipe, and said one way valve outlet is provided with pilot operated compound relief valve; Said oil cylinder control device for reversing is the zero lap two-position four-way valve, and the valve body two ends of said zero lap two-position four-way valve are provided with the feedback oil groove, is provided with the rapid reversal valve core in the feedback oil groove; The in-oil cylinder piston of said vibration two ends are provided with the supercharging boss, and cylinder block is provided with the supercharging groove that adapts with the supercharging boss, and the supercharging groove is connected with said feedback oil groove through oil pipe; The piston rod of said vibration oil cylinder connects pressure roller, and the piston rod of vibration oil cylinder is combined with fairlead.
The internal circular surfaces of said fairlead is provided with a plurality of cannelures, and the cross section of said cannelure is triangular in shape.
Said fairlead is provided with the oil input channel and the oil road that can lead to the fairlead fitting face.
Said oil input channel is positioned at the centre position of fairlead, and said oil road is positioned at the both sides of fairlead.
Said vibration oil cylinder and pressure roller are that vertical direction is arranged.
Said pressure roller is located on the support with the vibration oil cylinder, and said support is connected on the road roller frame through hydraulic cylinder.
Adopt the beneficial effect of technique scheme: the hydraulic vibration press-roller device of this directional vibration road roller is made up of with the hydraulic vibration device that is connected with pressure roller pressure roller; Hydraulic vibration device is made up of vibration oil cylinder, oil cylinder control device for reversing and Hydraulic Station; Oil cylinder control device for reversing control vibration oil cylinder is realized straight reciprocating motion; The vibration oil cylinder is vertical layout in concrete the installation, realizes the up-down vibration compacting so it drives pressure roller.Through regulating adjustable throttling, the big I of this hydraulic vibration device hydraulic fluid flow rate changes thereupon, thereby changes the commutating frequency of vibration oil cylinder, realizes that the pressure roller vibration frequency can be adjustable continuously between 1-300Hz, and jolt ramming efficient is high.Piston rod at the vibration oil cylinder is combined with fairlead, and fairlead has played the effect of guide-localization to the bigger piston rod of load.On the internal circular surfaces of fairlead, be provided with a plurality of cross sections cannelure triangular in shape, can store oil in the cannelure, the store oil meeting produces irregular flowing in reciprocating motion, plays sealing function, has also ensured lubricated between fairlead and the piston rod simultaneously.When getting into granule foreign in the gap, triangular groove can be stored impurity, prevent because of the obstruction of granule foreign stuck.Store oil in the triangular groove can be played the effect of static pressure in fixed, has ensured piston rod reliable work under the operating mode of high frequency heavy load.
