A kind of HTGR reactor pressure vessel check device
Technical field
The technology belongs to pressure vessel check device field, and in particular to a kind of HTGR reactor pressure vessel inspection Look into device.
Background technology
HTGR is to make cooling agent, the high nuclear reactor of outlet temperature with helium.In the support of national " 863 " plan Under, from last century the eighties mid-term, China has carried out the research of high-temperature gas-solid two-phase flow, exploitation, the advanced nuclear energy system of forth generation One of technology of system.The heap-type equally exists nuclear reactor pressure container (the reactor pressure of similar presurized water reactor vessel).Reactor pressure vessel is placement nuclear reaction and bears the closed container of its huge operating pressure, is HTGR Key equipment in nuclear power station, have the characteristics that manufacturing technology standard is high, difficulty is big and the cycle is long, and be non-exchange set It is standby, it is necessary to assure it is perfectly safe reliable in lifetime of the nuclear power station more than 40 years.
In nuclear power station running, reactor pressure vessel is in high temperature, high pressure, the high environment radiated.With operation The increase of time, the metallicity of container material can be reduced gradually, and metal discontinuity can also produce, so being extremely necessary pair Pressure vessel is detected, and to find defect risk therein in time, can be handled as early as possible, so as to safeguard and protect Hinder the safety of nuclear power facility, avoid the occurrence of serious safe operation and nuclear leakage accident.
It is high radioactivity region inside container, because high temperature nuclear reactor uses helium after nuclear reactor pressure container is run in power station Gas makees cooling agent, and in the absence of the characteristics of opening container unloading shutdown.The inspection of HTGR reactor pressure vessel is from container Implement in outside.Summary situation needs the device of a set of reactor pressure vessel inspection that can implement with Remote, at present The world is not on HTGR commercialization power station reactor pressure vessel Examined effect, it is necessary to go out for the heap-type independent design A kind of nuclear power plant reactor pressure vessel check device, the check device are implemented to check outside pressure vessel.
The content of the invention
It is an object of the invention to:A kind of HTGR reactor pressure vessel check device is provided, implements nuclear power station Nuclear reactor pressure container inspection.
Technical scheme is as follows:A kind of HTGR reactor pressure vessel check device, check device position Between pressure vessel outer tube wall and cabin barrel, check device includes ring-shaped guide rail, track operation dolly, elevating lever, two axles Scanner, alignment pin directing mechanism, ring-shaped guide rail are to be spliced into whole annulus by multi-disc arc guide rail;Track operation dolly is located at , can orbital motion on ring-shaped guide rail;Elevating lever is installed in track transportation trolley, elevating lever lower end carries alignment pin and pointed to Mechanism, it can be fixed with pressure vessel bottom alignment pin control so that whole elevating lever keeps vertical state, realizes track operation dolly Accurate subregion on container excircle, two axle scanners are arranged on elevating lever, scanning module are installed thereon, available for examining Look into.
The elevating lever uses the aluminium section bar of quadrangle column, is assembled by more piece, so as to be formed from reactor cabin Long rack lead of the top to lower vessel portion.
The axle scanner is circular arc type structure, including preceding jacking mechanism, rear jacking mechanism, motor, scanning module, vertical Guide rail, two axle scanners are arranged on elevating lever, motor-driven gear, two axle scanners is moved up and down along elevating lever; The preceding jacking mechanism of two axle scanners is tentacle shape structure, positioned at the left and right sides of two axle scanner circular arc type structures, be can be used for Stretch pressure container outer tube wall, it is rear jacking mechanism on rear side of the middle part of two axle scanner circular arc type structures, it is backward Two tentacle shape structures, available for cabin barrel is held out against, upright guide rail is located on the circular arc of two axle scanners, can be on circular arc Horizontal movement, and scanning module is located on upright guide rail, can be moved up and down along upright guide rail.
The two axles scanner is arranged on elevating lever, is mediated between elevating lever by rack-and-pinion, and guide wheel rolls branch Support.
The remarkable result of the present invention is:Forms of motion is simple, and Bit andits control is accurate, it is not necessary to which additional coordinates are changed.Together When track operation dolly on arrange elevating lever automatic lifting component, the combination of two directions of motion, realize that scanning axle is implemented outside container Surface any position checks.
