Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
See Fig. 1-Fig. 6, it is structural representation of the present utility model, a kind of coke oven main flue of the utility model panel turnover device, comprise the split sealing frame be fixed on main flue 15 inwall, can around rotating plate shaft 6 rotate and can with two panel turnover mechanism of sealing frame fitted seal and the turnover panel operating mechanism be positioned at above main flue 15, described pair of panel turnover mechanism is symmetrical set, and realizes interlock by turnover panel operating mechanism.
Described pair of panel turnover mechanism comprises left panel turnover mechanism and right panel turnover mechanism, and left and right turnover panel 4,5 is fixed in main flue 15 respectively by rotating plate shaft 6, and the shaft extension side at rotating plate shaft 6 top is provided with bearing spider 8, and rotating plate shaft 6 is connected with bearing spider 8 by bearing 7.
Described split sealing frame is made up of top seal frame 1, side seal frame 2 and sealed bottom frame 3.
Described pair adopts metal covering firmly to seal between panel turnover mechanism and sealing frame and between the left and right turnover panel 4,5 of two panel turnover mechanism.
Described turnover panel operating mechanism forms 9 and connecting rod 10 by removing, and left and right turnover panel 4,5 axle top is fixed respectively and left and rightly removed 9, connecting rod 10 two ends respectively with left and right remove 9 hinged.
Described left and right removing is respectively equipped with scale card 12 below 9, scale card 12 is provided with multiple pilot hole along removing 9 turning directions, left and right removing is provided with pin hole correspondence position on 9, and left and right removing is fixed by the be connected location that can realize on different angles of fastening screw 13 with pilot hole 9.
Described scale card 12 two ends are provided with backstop apparatus 14, to the left and right rotary spacing removed 9.
In the utility model, split sealing frame is made up of top seal frame 1, side seal frame 2 and sealed bottom frame 3, top seal frame 1 is fixed on main flue 15 upper surface, side seal frame 2 is fixed on main flue 15 sidewall, sealed bottom frame 3 is fixed on bottom main flue 15, and three combines the complete sealing frame structure of rear formation one.
The form that the sealing frame of left and right two turnover panels 4,5 and respective side adopts metal covering firmly to seal seals, and the sealing between left turnover panel 4 and right turnover panel 5 also relies on metal covering each other firmly to seal realization.
Rotating plate shaft 6 has two, is respectively used to connect left turnover panel 4 and right turnover panel 5, becomes the respective independent rotating shaft of left turnover panel 4 and right turnover panel 5.
Bearing spider 8 is fixed on main flue 15 upper surface, and rotating plate shaft 6 is connected with bearing spider 8 by bearing 7, and for limiting the radial and axial motion of rotating plate shaft 6, the bottom of rotating plate shaft 6 is stretched in the axis hole of sealed bottom frame 3, to increase the rigidity of rotating plate shaft 6.
Left and right removing is connected with the spindle nose of two rotating plate shafts 6 respectively 9, applies moment of torsion for giving rotating plate shaft 6.
