Description
Technical field
The invention belongs to integral reactor heap roof construction, be specifically related to a kind ofly be fixed on turning guiding and the stack top cable crane span structure of no-mobile reactor top cable of being used for above heap roof construction on civil engineering platform.
Background technique
Integral reactor heap roof construction is positioned at the upper of reactor pressure vessel, primarily of formations such as pressure vessels top cover, control rod drive mechanisms (CRD) (CRDM), CRDM antidetonation bearing device, top cover suspender, stack top cable bracket and cable testing bridges.
Be provided with CRDM power cable above heap roof construction and measure in cable, heap and measure the various cable such as cable, vibration detection cable, these cables need to be connected with the cable connection panel be arranged on civil engineering platform after heap roof construction is drawn.And stack top cable crane span structure is just as the bridge between top, heap top and civil engineering platform, serves and stack top cable fixed and is directed to the effect on civil engineering platform.
During reactor operation, cable testing bridge is set level, thus stack top cable is directed on civil engineering platform, stack top cable is connected with the cable connection plate on civil engineering platform; And in reactor refuling/maintenance period, need the cable connection plate on stack top cable and civil engineering platform to remove, cable testing bridge is retracted into vertical position, then leaves whole heap roof construction under order reactor pit.
At present in domestic and international pressurized-water reactor nuclear power plant reactor roof construction, stack top cable is all be directed to civil engineering platform by cable testing bridge above heap roof construction, then be connected with wire board place, and the structure of cable testing bridge is one end fixes the other end turning mode freely, fixed end is positioned at above heap roof construction, free end is positioned on civil engineering platform, and when therefore cable testing bridge is retracted into vertical position, whole cable testing bridge is erected in the top of heap roof construction.
And due to cable testing bridge size larger, after this mode overturns, mainly will bring following problem: on reactor axial direction, highly higher when cable testing bridge is vertical, to the height of heap roof construction be increased, bring pressure to top cover suspender, the heap lifting of roof construction and the height of containment vessel; In radial directions, add the radial dimension above heap roof construction, affect the use of follow-up overall bolt stretching machine, and the Split type bolt stretcher ring gauge on top cover suspender is had an impact, namely need top cover suspender to remove before cable testing bridge is overturn, again suspender is installed to after cable testing bridge upset on heap roof construction, which adds the operating time, be unfavorable for Economy and the Security of reactor.
Summary of the invention
A kind of being fixed on is the object of the present invention is to provide turningly on civil engineering platform to be used for guiding and the stack top cable crane span structure of no-mobile reactor top cable, to overcome prior art above shortcomings above heap roof construction.
For achieving the above object, the technical solution used in the present invention is:
One is fixed on turnover stack top cable crane span structure on civil engineering platform, comprises cable connection plate, cable testing bridge, supporting base, fixed base and supporting frame; Reactor roof construction is positioned at the central authorities of civil engineering platform, and civil engineering platform is concrete structure; Supporting base is anchored in civil engineering platform; Cable testing bridge is between reactor roof construction and civil engineering platform, and its one end is flexibly connected with supporting base, and this end is turning is more than or equal to 90 degree; Be provided with supporting frame above cable testing bridge, supporting frame is made up of a frame structure and a pull bar, and frame structure side is connected with the top of cable testing bridge, and the opposite side of frame structure is connected with pull bar; Fixed base is anchored in civil engineering platform, is positioned at the outside of supporting base, and is positioned on the center line of cable testing bridge; The other end of cable testing bridge is provided with two supporting legs; Cable connection plate is arranged on the top of reactor roof construction; When cable bridge horizontal is placed, two supporting legs on cable testing bridge are supported on PRV head package superstructure; When cable testing bridge is turned to vertical position, supporting frame pull bar is connected with fixed base.
Described supporting base upper end is U-shaped block.
One end of described cable testing bridge is connected with the U-shaped block of supporting base by bearing pin.
Described cable testing bridge is double-deck or three layers of bridge-like structure.
The top of support frame as described above frame structure side and cable testing bridge is by pinned connection, and the opposite side of frame structure is connected with pull bar by screw thread.
The end of described pull bar is provided with U-shaped block structure.
Described fixed base upper end has an attachment hole, and when cable testing bridge is turned to vertical position, U-shaped block and this attachment hole of supporting frame pull bar pass through pinned connection.
Beneficial effect acquired by the present invention is:
The present invention is by changing traditional turning structure of cable testing bridge be fixed on heap roof construction into be fixed on civil engineering platform the turning structure of cable testing bridge, and cable connection plate is moved on on heap roof construction from civil engineering platform, thus reduce axis and the radial dimension of heap roof construction, decrease operating procedure and the operating time of heap roof construction, thus improve Economy and the Security of reactor.This is simple and reliable for structure, economic and practical.
