Description
Technical field
The utility model is related to a kind of paver horizontal slope instrument to assist accurate calibration device.
Background technology
With the fast development of China Higher grade highway, largely make in road subbase course, base and Construction of Asphalt Pavement
With having the function of the paver of Automatic Levelling, to ensure surface evenness, meet vehicle traveling to the property such as speed and comfort
It can requirement.
Paver can be divided into two class Automatic Levelling modes at present：Absolute standard is levelling and relative datum is levelling, wherein absolutely
Levelling benchmark is steel wire rope benchmark Automatic Levelling mode, and levelling relative datum is the levelling mode of equalizer bar benchmark.Using horizontal slope instrument
It is levelling be exactly paver wherein-side uses the absolute standard Automatic Levelling mode of steel wire rope benchmark, another-side passes through horizontal slope instrument
To set road gradient, the paving thickness of guarantee horizontal slope instrument place side, flatness, so this side of horizontal slope instrument is according to relatively another
The paving thickness of side carries out the mode of relative datum Automatic Levelling.Therefore, this method of paving is that absolute standard is levelling and phase
The combination of levelling two ways to benchmark.
Using horizontal slope instrument leveling method, typically after the complete stable native underlayment of laying of roadway, in opposed flattened work
It carries out using during base layer construction on face.
The advantages of horizontal slope instrument leveling method and defect：
The advantages of using horizontal slope instrument leveling method：（1）Because horizontal slope instrument cooperation side steel wire rope benchmark uses, so sharp
Steel wire rope is not needed to horizontal slope instrument side, without measuring, driving piles, unwrapping wire, greatly reduces workload.（2）It is if terraced
Shape paving operation, in the both sides on road using steel wire rope benchmark, the paver of the trapezoidal front that paves uses horizontal slope instrument at middle seam, after
The paver in face can be levelling using piston shoes or Sonar Probe in the face that paves of preceding machine at seam, does not have in road thus
Aluminium alloy nose girder is set up at longitudinal center joint, the work of reduce bracing wire, setting up, adjust, carrying aluminium alloy nose girder can greatly reduce
Operating personnel improves work efficiency.（3）In trapezoidal paving operation, front and rear two pavers must maintain a certain distance,
To set up aluminium alloy nose girder at the longitudinal seam between two machines, Field Force need to frequently be interspersed in paver and vehicle when setting up
Between, there are security risks, these problems are can effectively avoid using horizontal slope instrument.（4）It is too late because setting up aluminium alloy nose girder sometimes
When or because of site machinery, vehicle and personnel, knock aluminium alloy nose girder over, influence construction speed, the speed that paves can be improved using horizontal slope instrument
Degree.（5）Improve construction quality, aluminium alloy nose girder set up at road longitudinal seam, need to from both sides steel wire rope row bracing wire, as
Set up the datum grade of nose girder, due to exist from two side guys when by bracing wire tensile force not-and nose girder set up and adjust inaccurate people
To influence, it is sagging that bracing wire is also easy to produce amount of deflection, and nose girder absolute altitude is caused to be not allowed, and can effectively avoid these problems using horizontal slope instrument.
Although having above-mentioned advantage using horizontal slope instrument, also there are following defects in practice of construction：（1）The horizontal slope instrument gradient is set
Put, tuning performance it is relatively poor, needed after starting through measure pave after the left and right sides (absolute altitude) height difference calculate the gradient, further according to slope
The thickness of this side of degree adjustment horizontal slope instrument, until paving thickness is consistent with design grade, is at this moment susceptible to joystick
The gradient shown on (button) box and reality are inconsistent, can not be checked in time.（2）Horizontal slope instrument reaction speed is slower,
When normal straight section paves, the horizontal slope on road surface is generally 2%, in the case where the gradient and paving thickness are constant, by adjusting control
Handle (button) processed, makes gradient show value consistent with actual grade, horizontal slope instrument goes to auto state.But paver enters bend
When, it needs constantly to control the gradual change gradient by adjusting joystick (button), and horizontal slope instrument reaction speed is slow, makes control
The slope change value shown on box, often with practical inconsistent, operating personnel are often difficult to know the two actual error value, can not
Carry out real time calibration.（3）Horizontal slope instrument low precision, after horizontal slope instrument works normally, paver is according to level(l)ing bubble on screed
The variation of the gradient is observed in position, and precision is poor, it is impossible to accomplish precise calibration to the steel wire rope benchmark of opposite side.
