Frame is connected to outer climb on vehicle guide rail with fixing axle bolster and slides, and motor driven speed reducer rotation, band movable sprocket rotates, sprocket wheel occlusion
Be fixed on and climb guiding chain above vehicle guide rail outside, carry out chain conveyer so that climbed outside X-ray production apparatus outside vehicle and imager climb vehicle along
Circular orbit synchronizing moving.
3. a kind of outer exposure type pipeline digital imaging detection device for detecting of X-ray according to claim 1, it is characterised in that：Outside
Vehicle guide rail is climbed using steel spring plate machine-shaping, but is not limited to steel spring plate, is also possible to stainless steel plate, cold-rolled steel sheet.
4. a kind of detection method of the outer exposure type pipeline digital imaging detection device for detecting of X-ray according to claim 1, special
Sign is：The first step will climb vehicle guide rail opening and be placed in steel pipe to be detected close to commissure, passes through chain briquetting with screw outside annular
Guiding chain is fastened on outer climb above vehicle guide rail；Second step, mounting and adjusting adjustable support seat, so that climbing vehicle guide rail position outside
It sets concentric with outer diameter of steel pipes, is tensed to lock with guide rail pinch grip and be connected and fixed outer vehicle guide rail of climbing；Third step adjusts live bearing
Frame will climb outside vehicle and imager the bearing groove of climbing vehicle upper bearing (metal) frame outside X-ray production apparatus and climb vehicle guide rail with outer and be engaged, and synchronous adjustment X is penetrated
The sprocket wheel for climbing vehicle outside vehicle and imager is climbed outside line machine to be engaged with chain is oriented to；4th step installs X-ray production apparatus and imager, adjustment
X-ray machine X window center is aligned with imager center with weld seam；5th step, open distal end controller pass through wireless module and driving
Module, which controls to climb outside vehicle and imager outside mobile X-ray production apparatus respectively, climbs vehicle into 180 degree relative position, synchronizes and opens X-ray machine X work
It opens imaging plate to work, is climbed outside vehicle and imager outside control X-ray production apparatus and climb vehicle circumferentially track synchronous rotation, carry X-ray
Machine is synchronous with imager to be relatively rotated one week along steel pipe；6th step, imager receive the X-ray that other side transillumination comes and turn
It changes picture into, signal is sent to by remote controller by wireless module in real time, carry out Real-time Imaging and achieve to put on record；7th
Step stops operating after the detection for completing whole weld seam for one week of walking, and X-ray and imager are closed in control, completes this section of weld seam
Detection；8th step after detection, removes adjustable support seat, will climb vehicle guide rail and is moved to together together with the vehicle of climbing above it
Lower commissure to be detected together, reinstalls adjustment adjustable support seat, repeats the 5th step, the 6th step is detected.
