Abstract
The utility model relates to a nuclear power station reactor field of overhauing, concretely relates to inner hull carbon seal ring dismounting device on subassembly of reactor upper portion. The device includes semi -ring I, semi -ring II, handle I, handle II, and semi -ring I, semi -ring II constitute the ring, semi -ring I, its one end reciprocal anchorage of semi -ring II just can rotate relatively, handle I, handle II are installed to semi -ring I, the semi -ring II outside, there is the pusher dog at semi -ring I, semi -ring II inboard middle part. Application inner hull carbon seal ring dismounting device on subassembly of reactor upper portion can ensure the safe inner hull carbon seal ring that dismantles to eliminate the great risk of the sealed face fish tail of inner hull that former dismantlement method exists, avoid the direct economic loss that the parts replacement brought.
Description
Technical field
The utility model relates to nuclear power plant reactor maintenance field, is specifically related to pneumatic shell graphite grazing circle stripping assembly on a kind of reactor upper element.
Background technology
Nuclear power plant reactor upper element top cover have with lower linking tube: 121 rod drive mechanism adapters, 18 neutron temperature Measurement channel tube bank adapters, 1 reactor exhaust adapter and an exhaust for subsequent use adapter. Wherein, 121 rod drive mechanism adapters are provided with 103 rod drive mechanism pneumatic shells and 18 blind plates. Pneumatic shell and blind plate and adapter trim byThe pure graphite grazing circle of model andThe reinforced graphite grazing circle of model realizes sealing. The reactor disassembling overhaul of every every four year need to remove 103 pneumatic shells and 18 blind plates, removes graphite grazing circle simultaneously.
RightWhen the reinforced graphite grazing circle of model carries out dismantlement work, former method for dismounting inserts between sealing-ring and pneumatic shell trim by force with copper screwdriver and pries open sealing-ring, then takes off graphite grazing circle. This method is adopted to there is damage pneumatic shell trim and cause the material risk that pneumatic shell damages.
Summary of the invention
The technical problems to be solved in the utility model is to provide pneumatic shell graphite grazing circle stripping assembly on a kind of reactor upper element, avoids using brute-force dismounting pneumatic shell graphite grazing circle, eliminates pneumatic shell sealing face damage risk.
For solving the problems of the technologies described above, pneumatic shell graphite grazing circle stripping assembly on a kind of reactor upper element of the utility model, this device comprises semi-ring I, semi-ring II, handle I, handle II, and semi-ring I, semi-ring II form annulus; Semi-ring I, its one end of semi-ring II are mutually fixing and can relatively rotate; Handle I, handle II are installed outside semi-ring I, semi-ring II; Semi-ring I, semi-ring II middle inside have pusher dog.
Described semi-ring I and the non-coupling end of semi-ring II have the connecting pin bores and joint pin that cooperatively interact.
Semi-ring I and semi-ring II working face there are top positioning boss and bottom positioning boss.
Advantageous Effects of the present utility model is: use pneumatic shell graphite grazing circle stripping assembly on reactor upper element can guarantee dismounting pneumatic shell graphite grazing circle, and the pneumatic shell trim eliminating the existence of former method for dismounting draws the material risk of wound, avoids the direct economic loss that parts replacement brings.

In figure: bottom 1 pneumatic shell, 2 reinforced graphite grazing circles, 3 handle I, 4 semi-ring I, 5 semi-ring II, 6 handle II, 7 connecting pin bores, 8 fixed pin holes, 9 handle installing holes, 10 top positioning boss, 11 pusher dogs, 12 bottom positioning boss.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 2,3, 4, pneumatic shell graphite grazing circle stripping assembly on practical novel a kind of reactor upper element, this device comprises semi-ring I4, semi-ring II5, handle I3, handle II6, and semi-ring I4, semi-ring II5 form annulus; Semi-ring I4, its one end of semi-ring II5 are mutually fixed by pin and can be relatively rotated; At handle installing hole 9, handle I3, handle II6 are installed respectively outside semi-ring I4, semi-ring II5; Semi-ring I4, semi-ring II5 middle inside have pusher dog 11.
Semi-ring I4 and the non-coupling end of semi-ring II5 have the connecting pin bores 7 and joint pin 13 that cooperatively interact, play the role of positioning when dismantling operation.
Semi-ring I4 and semi-ring II5 working face there are top positioning boss 10 and bottom positioning boss 12. During the dismounting operation of pneumatic shell graphite grazing circle, top positioning boss 10 is close under pneumatic shell layer sealing surface upper step, and bottom positioning boss 12 is stuck in pneumatic shell foot end face, and both cooperations realize stripping assembly location.
During work, pneumatic shell suspender is connected with pneumatic shell top; Cantilever is used to sling pneumatic shell to correct position; Hold pneumatic shell graphite grazing circle stripping assembly two ends handle, break two semi-rings into two with one's hands, fixed stripping assembly according to reinforced graphite grazing circle present position; Two semi-rings are closed up, by stripping assembly under both hands, until graphite grazing circle drops after determining stripping assembly pusher dog alignment sealing-ring graphite part; Cleaning pneumatic shell trim, it is ensured that graphite grazing circle top stiffening web is removed.
Adopting does not occur pneumatic shell trim to damage event after pneumatic shell graphite grazing circle special demounting device dismounting pneumatic shell graphite grazing circle on reactor upper element, plays good equipment benefit and economic benefit.
