Specific embodiment
Below in conjunction with the accompanying drawings the specific embodiment of the present invention is described further:
See Fig. 1-Fig. 6, be the structural representation of the present invention, a kind of present invention coke oven main chimney flue panel turnover device, including fixation
Split sealing frame on main chimney flue 15 inwall, can rotate around rotating plate shaft 6 and can be with double panel turnover mechanisms of sealing frame fitted seal
With the turnover panel operating mechanism positioned at main chimney flue 15 top, described pair of panel turnover mechanism is symmetrical set, and can operate machine by turnover panel
Structure realizes linkage.
Described pair of panel turnover mechanism includes left panel turnover mechanism and right panel turnover mechanism, and left and right turnover panel 4,5 passes through rotating plate shaft 6 respectively
It is fixed in main chimney flue 15, the shaft extension side at rotating plate shaft 6 top is provided with bearing spider 8, and rotating plate shaft 6 is propped up by bearing 7 and bearing
Seat 8 connection.
Described split sealing frame is made up of top sealing frame 1, side seal frame 2 and sealed bottom frame 3.
Described pair adopts metal covering hard between panel turnover mechanism and sealing frame and between the left and right turnover panel 4,5 of double panel turnover mechanism
Sealing.
Described turnover panel operating mechanism is formed 9 and connecting rod 10 by removing, and left and right removing is fixed on left and right turnover panel 4,5 axle tops respectively
9, connecting rod 10 two ends respectively with left and right remove hinged 9.
Described left and right removing is respectively arranged below with graduated disc 12 9, on graduated disc 12 along remove 9 rotation directions are provided with multiple
Location hole, left and right removing is provided with pin hole correspondence position on 9, and left and right removing passes through joining of fastening screw 13 and location hole 9
Conjunction connects the positioning that may be implemented in different angles and fixes.
Described graduated disc 12 two ends are provided with backstop apparatus 14, to the left and right rotary spacing removed 9.
In the present invention, split sealing frame is made up of top sealing frame 1, side seal frame 2 and sealed bottom frame 3, and top is close
Envelope frame 1 is fixed on main chimney flue 15 upper surface, and side seal frame 2 is fixed on main chimney flue 15 side wall, and sealed bottom frame 3 is fixed on total cigarette
Road 15 bottom, forms a complete sealing mount structure after three's combination.
Left and right two turnover panels 4,5 to be sealed in the form of the hard sealing of metal covering with the sealing frame of respective side, left turnover panel 4
The metal covering that sealing and right turnover panel 5 between also depends on each other seals realization firmly.
Rotating plate shaft 6 has two, is respectively used to connect left turnover panel 4 and right turnover panel 5, becomes each of left turnover panel 4 and right turnover panel 5
From independent gyroaxis.
Bearing spider 8 is fixed on main chimney flue 15 upper surface, and rotating plate shaft 6 is connected with bearing spider 8, for limiting by bearing 7
The radial and axial motion of rotating plate shaft 6 processed, the bottom of rotating plate shaft 6 is stretched in the axis hole of sealed bottom frame 3, to increase rotating plate shaft 6
Rigidity.
Left and right removing is connected with the spindle nose of two rotating plate shafts 6 respectively 9, for applying moment of torsion to rotating plate shaft 6.
