When, firstly, whole device is connected extraneous power supply, start third motor 21, third motor 21 is made by chain 19 and sprocket wheel 20
The rotation of first directional wheel 6 by the elongation of electric hydaulic bar 4, can pass through fixed frame so that device is moved forward and backward
5 make the second directional wheel 18 contact ground, to support whole device, device can be made to carry out by the second directional wheel 18 left
It moves right, as procedure described above, device can be moved to the road for needing to smooth out by the moving process of control device all around
On face；
When device is gone forward positioned at road surface, need to carry out the working width of regulating device, herein mistake according to the width for smoothing out road surface
Cheng Zhong can be such that device is moved left and right, move backward the supportive body 2 of device two sides, just by the second directional wheel 18
It can change the size between supportive body 2, to make the contour length of support rod 8 change, when the structure of support rod 8 changes
When change, the position for smoothing out main body 11 can be changed correspondingly by fixing axle 10, make to smooth out spread length of the main body 11 on support rod 8
Meet the width needed for highway smoothes out, and when the contour length of support rod 8 changes, above fixed link 22 can lead to
It crosses movable axis 9 and carries out position change, so that the distance between adjacent fixed link 22 be made to change, contraction pole 23 will be made in fixed link
Position change on 22, and then make the length of fixed link 22 and contraction pole 23 and meet the length of support rod 8 always, while can also
To reinforce the stability of support rod 8；
When the working size of device is adjusted to when smoothing out size with highway and being consistent, first motor 1 can be started, first is electric
Machine 1 can be changed to control the lifting work of link block 7 by the positive and negative rotation of control threaded rod 17 and smooth out main body 11
Operating position height touches the wiping tablet 14 for smoothing out 11 lower end of main body and the road surface smoothed out is needed then to start each floating
The second motor 15 in main body 11, the second motor 15 rotate wiping tablet 14 in protective fence 13 by rotation axis 12, are smoothing out
Under 14 rotary state of plate, can road pavement carry out floating work, while start third motor 21 make the first directional wheel 6 rotate,
Can be so that whole device be moved along highway, in device moving process, each wiping tablet 14 can be easily accomplished
The floating work of road pavement, the content for being above the course of work of whole device, and being not described in detail in this specification, example
Such as first motor 1, electric hydaulic bar 4, the second motor 15, third motor 21, belong to well known to professional and technical personnel in the field
The prior art.
