Description
Technical field
This utility model is related to a kind of attitude control system, more particularly to a kind of paver screed gesture stability system
System, belongs to technical field of paver control.
Background technology
At present, when paver is normally floated paving operation, as shown in figure 1, screed is acted on by many power, there is large arm
Pull strength F1, stockpile resistance F2, frictional resistance F3, the counteracting force F4 that vibrates, in the face of backplanes support power F5 and screed gravity
F6, these power are in screed during dynamic equilibrium and stablize in certain position, once wherein some power produces change, will destroy
The stress balance of screed, makes the position of the screed hinge around before large arm swing up or down, changes.Dynamically putting down
Under weighing apparatus quick condition, screed base plate and paver basic unit road surface define an angle, the referred to as elevation angle；Ironing Board position and its
The stability at the elevation angle is towed the impact that a location A fluctuates up and down and multiple power suffered by screed itself change.
Elevation angle size indicates the stress of screed, generally 1 °～2 ° of the normal optimum range of elevation angle numerical value, faces upward
Angle is too small or the excessive surface evenness that satisfies the need is all bad, the elevation angle be less than 0 ° of referred to as negative elevation angle, i.e. screed base plate tailing edge leave and pave
Layer surface, the elevation angle shows that more greatly the impact to screed dynamic equilibrium attitude for the material resistance change is bigger.
Ideally, if keeping the screed elevation angle constant in floating paving process, then the road surface paving out is
Definitely smooth；But in actual floating paving process, by basic unit road surface is uneven and material resistance suffered by screed is become
Change, lead to the screed elevation angle to vary constantly, the change at the elevation angle is especially widely varied can be put down to paving concrete pavement
Whole degree causes serious adverse effect.
Current attitude control method is usually, in paver direction of advance, in screed installed in front surface level-meter or
Equalizer bar, the surface level-meter being caused with the change of material resistance suffered by screed by the uneven change in basic unit road surface by measurement or
Angle or change in displacement at equalizer bar mount point, export up and down action control signal to levelling oil cylinder, to realize overcoming interference fringe
The elevation angle change coming；This two kinds of interference variations can cause the elevation angle to change, and then leads to angle or displacement at surface level-meter mount point to become
Change, interference variations more big-elevation change fluctuation is also bigger.But, due to not having to the amplitude that the elevation angle changes in this control process
Limit, when leading to be widely varied, can still cause serious adverse effect to paving concrete pavement flatness.
