Fig. 9 has provided opposite planar position and the shape of installing plate 8-5, control box 8-20, round chute 8-7 and electric switch 8-9.Control box 8-20 by screw with the slide block 8-19 of screw rod 8-6 worm drive on.Roller 8-17a on the electric switch 8-9 and 8-17b are touched by square slide bar 8-13.Pointer 8-18 is installed on the control box 8-20, is used to indicate the position of control box 8-20 on scale 8-15.
Figure 10 is the control panel figure of control box 8-20.Pillar lifting hand switch 8-22 and lifting indicator lamp 8-21 and pointer 8-18 are installed on control panel.
Figure 11 has represented the connection of regulating wheel 8-12 and tensioning torsion spring 8-23.When square slide bar 8-13 rose or descend, backguy 8-1 drove regulating wheel 8-12 forward or reverse, and regulating wheel makes tensioning torsion spring 8-23 tighten or discharges, makes backguy 8-1 have pulling force all the time.Can change the pulling force of backguy 8-1 by the initial position of regulating tensioning torsion spring 8-23.
Figure 12 is the structure chart of square slide bar 8-13.Demifacet was processed with get out of a predicament or an embarrassing situation B and locating slot 0 after demifacet was processed with the A that tops bar, left side before the square slide bar 8-13 left side, and square slide bar 8-13 right side is equipped with rolling bearing 8-24 up and down.
Because square slide bar 8-13 will link with machine milling depth datum spare side striker plate 24 by backguy 8-1, so the square slide bar 8-13 on the vertical direction is equivalent to the reference line parallel with the road surface.Generally speaking, the height and position that milling rotor point of a knife is touched the side striker plate 24 when waiting to mill the road surface is the zero-bit of the milling degree of depth, at this moment.The pointer 8-16 of square slide bar 8-13 points to the zero-bit of milling scale of depth 8-15.
When milling degree of depth auto-manual control transposition 8 state of a controls when being manual, electric switch is not powered.Press the pillar lifting hand switch 8-22 on the control panel, pillar will rise or descend, and the milling rotor rises thereupon or descends, and rising or decline indicator lamp 8-21 are with shinny simultaneously.Pointer 8-18 indicates the milling rotor terrain clearance or the milling degree of depth thereupon.Under manual state of a control, shake handle 8-2 and make control box 8-20 be elevated to the upward predetermined milling degree of depth of milling scale of depth 8-15.Then, will control transposition 8 state of a controls and get to automatically, the milling rotor will carry out operation by the predetermined milling degree of depth automatically.
When milling degree of depth auto-manual control device 8 state of a controls when being automatic, when electric switch roller 8-17a and 8-17b aimed at the locating slot 0 of square slide bar 8-13, electric switch did not have signal of telecommunication output, and this moment is for setting rotor milling depth location.When square slide bar 8-13 descends, promptly when elevation rising in road surface is raised milling depth datum spare side striker plate 24, the milling degree of depth is with thickening, electric switch roller 8-17a can press topping bar during A of square slide bar 8-13, electric switch is exported the signal of telecommunication that pillar rises, and gets back to the locating slot 0 of square slide bar 8-13 up to electric switch roller 8-17a.Like this, the milling rotor will be raised and rise with side striker plate 24, be raised to up to rotor on the milling depth location of setting.Otherwise, when square slide bar 8-13 rises, promptly when elevation reduction in road surface descends milling depth datum spare side striker plate 24, the milling degree of depth is with attenuation, electric switch roller 8-17b can press topping bar during B of square slide bar 8-13, electric switch is exported the signal of telecommunication that pillar descends, and gets back to the locating slot 0 of square slide bar 8-13 up to electric switch roller 8-17a.Like this, the milling rotor will descend with the decline of side striker plate 24, drops to up to rotor on the milling depth location of setting.Under automatic control state, when shaking handle 8-2 and making control box 8-20 be elevated to milling scale of depth 8-15 to go up the milling degree of depth of anticipation, the lifting along with control box 8-20 lifting automatically of milling rotor.
Also can design the pavement milling machine of another concrete structure according to above-mentioned principle.
