In nuclear power station running, reactor pressure vessel is in high temperature, high pressure, the high environment radiated.Increase along with the time of operation, the metallicity of container material can be gradually lowered, metal discontinuity also can produce, so being extremely necessary pressure vessel is detected, to find defect risk therein in time, can be processed as early as possible, thus safeguarding and ensure the safety of nuclear power facility, it is to avoid serious safe operation and nuclear leakage accident occur.
Nuclear reactor pressure container is after power station is run, and internal tank is high radioactivity region, owing to high temperature nuclear reactor uses helium to make coolant, and is absent from out the feature of container unloading shutdown.HTGR reactor pressure vessel checks to be implemented from outside of containers.Summary situation need a set of can Remote implement reactor pressure vessel check device, the current world is not about HTGR commercialization power station reactor pressure vessel Examined effect, being required for this heap-type independent design and go out a kind of nuclear power plant reactor pressure vessel inspection device, this inspection device checks from outside enforcement of pressure vessel.
Summary of the invention
It is an object of the invention to: provide a kind of HTGR reactor pressure vessel to check device, implement Nuclear Power Station reactor pressure vessel and check.
Technical scheme is as follows: a kind of HTGR reactor pressure vessel checks device, check that device is between pressure vessel outer tube wall and cabin barrel, checking that device includes ring-shaped guide rail, track operation dolly, elevating lever, two axle scanners, alignment pin directing mechanism, ring-shaped guide rail is to be spliced into whole annulus by multi-disc arc guide rail；Track operation dolly is positioned on ring-shaped guide rail, can orbital motion；Track transportation trolley is installed elevating lever, alignment pin directing mechanism is carried in elevating lever lower end, can fix with pressure vessel bottom alignment pin control, whole elevating lever is made to keep vertical state, realize the track operation dolly accurate subregion on container excircle, two axle scanners are arranged on elevating lever, it installs scanning module, can be used for checking.
Described elevating lever adopts the aluminium section bar of tetragon column, more piece assemble, thus forming the long tooth bar lead from reactor compartment roof to lower vessel portion.
Described axle scanner is circular arc type structure, and including front jacking mechanism, rear jacking mechanism, motor, scanning module, upright guide rail, two axle scanners are arranged on elevating lever, motor-driven gear, makes two axle scanners can move up and down along elevating lever；The front jacking mechanism of two axle scanners is tentacle shape structure, it is positioned at the left and right sides of two axle scanner circular arc type structures, can be used for stretch pressure container outer tube wall, two axle scanner circular arc type structures middle part on rear side of be rear jacking mechanism, it is two tentacle shape structures backward, can be used for holding out against cabin barrel, upright guide rail is positioned on the circular arc of two axle scanners, can horizontal movement on circular arc, and scanning module is positioned on upright guide rail, can move up and down along upright guide rail.
Described two axle scanners are arranged on elevating lever, and are mediated by rack-and-pinion between elevating lever, guide wheel rolling support.
The remarkable result of the present invention is in that: forms of motion is simple, and Bit andits control is accurate, it is not necessary to additional coordinates is changed.Elevating lever automatic lifting assembly arranged by track operation dolly, two direction of motion combinations, it is achieved scanning axle is implemented container outer surface any position and checked simultaneously.
