The utility model content
The defects that exists for solving prior art, the purpose of this utility model is to provide a kind of compact conformation, and volume is little, cost is low, vibration force concentrated on relatively exert oneself, vibration frequency is adjustable and can reach upper frequency, the directional vibration road roller that available power is high continuously.
For achieving the above object, the technical solution adopted in the utility model: this directional vibration road roller, have pressure roller and the hydraulic vibration device that is connected with pressure roller, it is characterized in that: described hydraulic vibration device is made of vibration oil cylinder, oil cylinder control device for reversing and Hydraulic Station, Hydraulic Station is connected with the oil cylinder control device for reversing, and the oil cylinder control device for reversing is connected the control commutation with the vibration oil cylinder; The moving oily output of described Hydraulic Station is made 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 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 the 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 the feedback oil groove, is provided with the rapid reversal valve core in the feedback oil groove; The in-oil cylinder piston of described 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 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.
The internal circular surfaces of described fairlead is provided with a plurality of cannelures, and the cross section of described cannelure is triangular in shape.
Described fairlead is provided with oil input channel and the oil road that can lead to the fairlead fitting face.
Described oil input channel is positioned at the centre position of fairlead, and described oil road is positioned at the both sides of fairlead.
Described vibration oil cylinder and pressure roller are that vertical direction is arranged.
Described pressure roller and vibration oil cylinder are located on the support, and described support is connected on the road roller frame by hydraulic cylinder.
Adopt the beneficial effect of technique scheme: the hydraulic vibration press-roller device of this directional vibration road roller is made of with the hydraulic vibration device that is connected with pressure roller pressure roller, hydraulic vibration device is made 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, therefore its band dynamic pressure roller is realized the up-down vibration compacting.By regulating adjustable throttling, the large 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 larger piston rod of load.Internal circular surfaces at fairlead is provided with a plurality of cross sections cannelure triangular in shape, can store oil in the cannelure, and 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 entering 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 that piston rod works under the operating mode of high frequency heavy load reliably.
