Description
Technical field
The invention belongs to locating device, be specifically related to a kind of welding seam ray detection and location device.
Background technology
Nuclear power station steam generator is used for the chilled water with the heat transferred secondary circuit of a circuit cools water, is used to produce steam and promotes the turbodynamo generating.Its low head is one and is cast into hemispheric spherical shell, interior compartment is separated into into end by a nickel-base alloy plate and goes out to hold two parts, every part all has the adapter of a manhole and the about 980mm of diameter of an about 406mm of diameter, about 50 ° of its angle, main pipe welding seam is positioned at the pipeline junction of taking over an ozzle and a circuit system, takes over wall thickness 95mm.
According to the requirement of coherence check standard, must carry out radiological survey X to the adapter safe end weld seam at this place, must use locating device and will finish radiological survey X.When carrying out sensitivity of film, radiographic source must be positioned on the central axis of trunk line inside, and film cassette is fixed on the weld seam outside, in order to improve image quality, the bearing accuracy of locating device has been proposed higher requirement.
At present domestic other unit does not have similar techniques and dedicated positioning device, external also have only the Framatome of France to research and develop the locating device that is used for similar position radiological survey X, but this technology is restricted to Chinese exports, because of finding the particulars of this cover orientation tool and the technology of use, so can't use for reference its design experiences.
Summary of the invention
The purpose of this invention is to provide a kind of bearing accuracy height, security performance is good, the main pipe welding seam ray detection and positioning device for nuclear power station steam generator of the high efficiency of inspection.
The present invention is achieved in that a kind of main pipe welding seam ray detection and positioning device for nuclear power station steam generator, it comprises the manhole stiff end that is installed on the manhole flange face, the manhole stiff end is by being connected with positioning end with spacing flexure spring axle, the positioning end outside connects pulley bracket, on described manhole stiff end, be provided with hoisting mechanism, hoisting mechanism connects the driving flexible strand, drive flexible strand and be connected on the pulley bracket, be connected with the guiding slip pipe at the head of positioning end along the sleeve outer wall of manhole stiff end.
Among the present invention, the manhole stiff end is fixed on an end of locating device on the manhole, make locating device increase an additional support, improved bearing accuracy, in addition, positioning end can utilize the position consistency of opening location and tested pipeline of pulley bracket, carries out the flexibility fine setting with stiff end, has improved bearing accuracy; Adopt the present invention, installation personnel needn't enter in the steam generator just can finish installation, has reduced the absorption of installation personnel to ray; Positioning end can once be finished by the position of using the guiding slip pipe to change radioactive source the transillumination that carries out repeatedly diverse location is installed, reduced the roentgen dose X that personnel receive, improved the work efficiency of checking, therefore remarkable advantage of the present invention is to have improved bearing accuracy, the work efficiency of security performance and inspection.
