With air lock door transmission system integral installation quality.
Brief description of the drawings
Fig. 1 is nuclear power station access lock schematic diagram.
Fig. 2 is the nuclear power station access lock transmission system overall structure diagram that the present invention is implemented.
Fig. 3 is nuclear power station access lock position line schematic diagram in embodiment.
Fig. 4 is that nuclear power station access lock simulates axle scheme of installation in embodiment.
Embodiment
With reference to specific implementation the invention will be further described with accompanying drawing, add in the de-scription more details with
It is easy to more fully illustrate and understands the present invention, but the present invention obviously can be come in fact with a variety of other modes different from this description
Apply, those skilled in the art can make similar popularization according to practical situations in the case of without prejudice to intension of the present invention, drill
Unravel silk, therefore should not be limited the scope of the invention with the content of this specific embodiment.
Illustrate the specific embodiment of the present invention referring to the drawings.
As shown in Figure 1 and Figure 2, the nuclear power station access lock that this example is implemented is by the inside and outside He of two fan structures identical hermatic door 01
Middle cabin 02 forms, and knife switch is divided into manual and electronic two states, and the effect of wherein final drive shaft 03 is close by inner side
Closure door commutator 04 transfers a torque to inner seal door hinge mechanism 05, lifting body 06, retaining mechanism 07, anti-reverse mechanism 08
Ensure the normal switch of gate.To ensure the steady of moment of torsion transmission, increase spring between final drive shaft and commutator input shaft
Shaft coupling 09.
As shown in figure 3, throwing of the gate tubular axis in horizontal plane and vertical plane is determined on sealing door frame polished surface
Hachure, and final drive shaft elevation line L2 is determined according to floor projection line L1.The projection line is moved in access lock sleeve again
On wall.Projection line L4 of the final drive shaft in vertical plane is determined according to vertical plane projection line L3.L2 and L4 intersection point is final drive shaft
Axle center.
Final drive shaft elevation line can use self-control divider calipers H1 to be translated.One piece of level is set below main shaft elevation line
Plate H2 simultaneously ensures the horizontal plate level, and divider calipers base can draw pin and final drive shaft elevation line on this level board slidably
Overlap, rotate divider calipers and the projection line is moved into main transmission axis hole and middle cabin inwall.
Piece simulation axle M1 of processing, its diameter is identical with gate final drive shaft diameter, and length is that final drive shaft joins with spring
Axle device length sum, one end processing axle sleeve can input axis connection with keyway with inside door commutator, and the other end can pass through main biography
Moving axis flange M2.
Simulation axle passes through final drive shaft flange, such as Fig. 4 axle sleeves one end and commutator input axis connection, now unclamps commutator
Carrier setting bolt, the installation site of adjustment simulation axle, makes its axis be overlapped in horizontal plane with the position location of vertical plane with projection line,
Adjusting commutator position and final drive shaft flange position simultaneously enables final drive shaft freely to rotate, and no bite abnormal sound is extremely existing
As.
Commutator support position, main transmission flange position after the completion of fixed-analog axial adjustment.Simulation axle is removed, first will
Spring coupling and commutator input axis connection, then final drive shaft is connected with spring coupling.Main transmission now, flange,
Commutator installation site is best position.
It was verified that using the nuclear power station access lock final drive shaft installation method of the present invention, replaced by a simulation axle
