Description
Technical field
The invention belongs to the making in road or other similar structure paving, machine, instrument or the auxiliary equipment technical field of reparation usefulness, be specifically related to vibratile compacter in the engineering machinery.
Technical background
According to the compacting theory, compacting can be divided into static(al) compacting, vibratory compaction and shock compaction; Vibratory compaction can be divided into single shaft, twin shaft and multiaxis vibrator according to vibrating wheels exciter structure difference, and the twin shaft vibrator is by relative rotation direction that changes twin shaft and the conversion that phase place reaches vibration mode, can realize that common vibratory compaction is that the twin shaft same-phase is rotated in the same way, oscillation compaction (twin shaft rotatable phase in the same way differs 180 °, the swing vibration force), horizontal vibration compacting (the double-axis reverse rotatable phase differs 180 °) and vertical vibration compacting (reverse rotation of twin shaft same-phase).
Common vibratory compaction be rely on that exciting device produces around exciting force, force to be compacted material granule resonance, make material do vertical vibration, sharply reduce the internal friction between soil particle, make particle close, compactness increases, thereby reaches the purpose of compacting.The characteristics of vibratory compaction are that its surface stress is little, and process time is short, and loading frequency is big, simultaneously can also be according to different pavers and shop layer thickness, and choose reasonable vibration frequency and amplitude to improve consolidation effect, reduce number of rolling.It is strong to have compaction capacity, and consolidation effect is good, characteristics such as production efficiency height.
Oscillation compaction is the principle that adopts soil mechanics soil alternation shear stress, (twin shaft rotatable phase in the same way differs 180 ° to the exciting eccentric block (axle) of symmetry installation and rotation synchronously in vibrating wheels, the swing vibration force), make vibrating wheels bear the change moment of torsion, to the ground continuous action, form the wave of oscillation of fore-and-aft direction, make material in horizontal plane, bear alternating shear power.Under the effect of this continuous alternating shear power, material will produce sharply distortion along the direction of shearing force, surface of shear slippage dislocation, and material granule is filled mutually, is rearranged, chimeric wedging thereby make, and reaches stable dense state.Realization is to being compacted the compacting of material at level and vertical both direction.Mainly be applicable to compacting bridge floor bituminous concrete shop layer, have compacting efficient height, consolidation effect good, bridge construction is destroyed characteristics such as little.
The horizontal vibration compacting is that symmetry is installed and 180 ° of twin shaft exciting eccentric blocks of reverse rotation phase phasic difference in vibrating wheels, when two eccentric block rotation certain positions, two eccentric forces that eccentric block produced are mutual superposition in the horizontal direction, make whole road roller steel wheel instantaneously present horizontal vibration trend, and to make a concerted effort on the horizontal direction be two exciting force sums that eccentric block produced at this.Make material bear alternating shear power in horizontal plane, material will produce sharply distortion along the direction of shearing force, surface of shear slippage dislocation, and material granule is filled mutually, is rearranged, chimeric wedging thereby make, and reaches stable dense state (rubbing the pressure effect).
The vertical vibration compacting is also referred to as the directional vibration compacting, it is the vertical orientation exciting force acting in conjunction that relies on mechanical sole mass and exciting device thereof to produce, reduce the internal friction of being pressed between material granule, and force soil particle resonance, make the soil particle redistribution, with the grogs wedging, reach the purpose of compacting soil.
At present domestic and international vibratory roller twin shaft vibrator, the relative rotation direction of twin shaft is single rotation in the same way (common vibratory compaction) or single reverse rotation (vertical vibration compacting), can not realize the mutual switching of these two kinds of functions, both there be not a kind of twin shaft vibrator can realize that twin shaft rotates relatively in the same way, also can realize the relative reverse rotation of twin shaft.This just defines the function performance of existing twin shaft vibrator.
Summary of the invention
Technical problem to be solved by this invention is to overcome the deficiency of the single exciting pattern of above-mentioned vibratory roller vibrating wheels vibrating device, provides a kind of vibratory roller twin shaft reasonable in design, simple in structure, that efficient is high, consolidation effect is good relative rotation direction mechanical switching exciter.
