Abstract
The invention relates to the field of radiological inspection of nuclear power cast steel members and discloses a multi-station inspection stand designed aiming at radiation sources of iridium 192, cobalt 60, thulium 170 and the like. The inspection table uses the radiation sources as the center and performs radiography inspection on a plurality of cast steel members, each cast steel member can move forwards and backwards in radial mode relative to the center of the radiation sources and can rotate surrounding axial leads of the cast steel members, thereby facilitating photo distribution. Theradiography inspection stand has the advantages of improving utilization rate of the radiation sources, reducing opening times of the radiation sources and radiation of gamma rays, reducing working intensity of operators, greatly improving working efficiency, stabilizing shooting quality, and ensuring a radiographic test (RT) process to be more convenient and reliable.
Description
Technical field
The present invention has announced a kind of manufacture method of nuclear power steel-casting radiographic examination (complete) platform, relate to steel-casting radioscopy field, be applicable to that many steel-castings check simultaneously, can be simultaneously accurate location, significantly improve work efficiency, guarantee that check obtains identical effect with single-piece.
Background technology
The steel-casting quality requirements of used in nuclear power station is very high, and quality policy is " quality first, safety first ", and quality objective is to meet nuclear safety codes and nuclear industry code requirement, can safe and reliable use.Along with greatly developing of domestic and international nuclear energy uses, being on the increase of newly-built nuclear power station needs a large amount of nuclear power steel-castings.In order to guarantee nuclear power steel-casting qualification rate 100%, zero-fault.This just requires every nuclear power steel-casting is carried out 100% RT check.Present situation is the single-piece Radiographic test RT, also wants open and close radiographic source and sealing chamber once, can only obtain an examination and test of products sheet position, and the film making plant factor is low.
Summary of the invention
The purpose of this invention is to provide a kind of nuclear power steel-casting radiographic examination (complete) platform, when mainly solving the RT check, low at single-piece radiography efficient, operator's labour intensity is big, radiographic source, sealing chamber switch frequency height, the difficult problem of the easy radiation of ray, set multistation at this check-out console, the ray that utilizes radiographic sources such as iridium 192, cobalt 60, thulium 170 to produce is the characteristics of launching to all around, once checks a plurality of foundry goods, and operation once can obtain a plurality of castings examination sheet position result.Reach and improve checkability greatly, convenient focal length, rotation foundry goods, the layout film adjusted during operation.Reduce radiographic source, sealing chamber switch number of times, reduce the x radiation x degree.
The objective of the invention is to realize with following technical scheme, integral body is by uniform a plurality of stations on the disc base, hanging on the disc centre position radiographic source equates to each station center position, each station connection is being detained planker, roll supporting with circle between planker catching groove and the base riser, the relative motion lead screw transmission, center line is installed with panoramic table on the planker, the four-jaw chuck that lengthens is being assembled in panoramic table central shaft upper surface, and the worm gear main member on the worm mesh panoramic table main shaft of locating on the planker face connects to be formed.Hanging radiographic source on the disc base center, to be equipped with equal distance to each station centre bit be 500-1200mm, and planker displacement is fixed point with the station center, moves radially distance along disc base and be ± 200mm.The four-jaw chuck that lengthens is being assembled in panoramic table central shaft upper surface, and elongated clamping jaw part material is nylon or tetrafluoroethene engineering plastics.Worm gear on the worm mesh panoramic table main shaft of locating on the planker face, the number of teeth of worm gear is Z2=72, and number of threads is Z1=1, when handwheel on the worm shaft rotates less than a circle, worm gear rotates less than a number of teeth, and the foundry goods slewing area on the panoramic table is 0 °-5 °.During operation, small-sized foundry goods manually is placed on the check-out console; Heavy castings can be lifted on the check-out console with driving, with clamping foundry goods on the four-jaw chuck.Handwheel on the rotational lead screw axle, the foundry goods center of adjusting respectively on each station meets the requirement of film making focal length to disc centre apart from reaching, film is arranged on each castings examination position, after once film making finishes, pull the handwheel on the worm screw more respectively, drive the worm gear drives panoramic table and rotate, select satisfied angle, the cloth sheet check of taking a picture again, up to the foundry goods full volumetric all check finish till.
The invention has the beneficial effects as follows compact conformation, the clamping foundry goods is firm, and the protection radiographic source is safe and reliable, and many stations just can double efficient more on the chassis, and quality inspection is stable, and the inspection cost expense descends significantly.
Description of drawings
Fig. 1 is front view of the present invention, wherein: 1, disc base, 2, radiographic source, 3, four-jaw chuck, 4, panoramic table, 5, worm screw, 6, worm gear, 7, planker 8, leading screw, 9 circles roll, and 10, riser.Fig. 2 is vertical view of the present invention, wherein: 11, lead screw shaft handwheel, 12, the worm shaft handwheel.
Embodiment
The present invention shows embodiment by its principle of work, opens the gate of check sealing chamber during use, lays out foundry goods at each station of indoor check-out console, clamps with four-jaw chuck 3.8 of 7 times leading screws of rotary planker are gone up handwheel 11, adjusting on each station the foundry goods center respectively reaches to the disc centre distance and meets the requirement of film making focal length, film is arranged on each castings examination position, after once film making finishes, shake the handwheel 12 on 5 of each worm screws more respectively, drive worm gear 6 drive panoramic tables 4 and rotate, select satisfied angle, the cloth sheet is taken a picture and is checked again.One-tailed test finish back upset foundry goods fixing after, more successively to the other end film making of taking a picture, up to the foundry goods full volumetric all check finish till.
