Abstract
The invention provides an X-ray flaw detection device for a tapered pipeline. The X-ray flaw detection device comprises a traveling trolley, wherein a screw sleeve is connected to the traveling trolley by virtue of a first screw; a circumferential radiation X-ray flaw detector is connected to the screw sleeve by virtue of a bracket; the centers of the screw sleeve and the circumferential radiation X-ray flaw detector are positioned on the same horizontal line; two sections of internal threads in the opposite directions are arranged inside the screw sleeve; the upper part of the screw sleeve is connected with a top contact block by virtue of a second screw; the length of the first screw is equal to that of the second screw; the height of the traveling trolley is equal to that of the top contact block; two sides of the screw sleeve are wound by pull ropes in the opposite directions. By virtue of the X-ray flaw detection device for the tapered pipeline, the axis position of the X-ray flaw detector on a revolved body can be conveniently adjusted, and flaw detection is facilitated.
Description
technical field:
The present invention relates to a kind of device tapered pipeline being carried out to carrying out flaw detection, be specifically related to a kind of tapered pipeline x-ray inspection device.
background technology:
X-ray inspection, industrially has a very wide range of applications, and it is both for metal inspection, also for nonmetal inspection.X-ray flaw detector divides directed radiation, circumferential radiation two kinds.Directed radiation is fixing, and beam radiation coning angle is generally 40 ° ~ 45 ° scopes.Circumferential radiation beam is becoming 360 ° of vertical direction circumferentially radiation X rays simultaneously, this is for the circular weld detecting large-caliber pipe fittings and spherical container, the flaw detection photograph work of whole weld seam can be completed by single exposure, thus can improve detection efficiency widely.
Detection for metallic conduit generally needs to select circumferential radiation x-ray flaw detector, existing circumferential radiation x-ray flaw detector requires that defectoscope needs to be placed on inside pipeline in the course of the work, and require that radiographic source can accurately be focused inside solid of revolution, this is for the pipeline of reducing, arrange different support focusings in practical operation to bother very much, cause detection efficiency low.
In order to solve the problem, Chinese patent CN201320535949 discloses a kind of solid of revolution x-ray inspection device, it comprises mounting platform, described mounting platform is installed circumferential radiation x-ray flaw detector, the radiation center of described circumferential radiation x-ray flaw detector is positioned at the center of described mounting platform, described mounting platform is provided with adjusting knob, described adjusting knob coaxially connects driving gear, described driving gear engages with follower gear one, described follower gear one engages with follower gear two, inside described follower gear one, screw rod one is installed, described screw rod one top installs, inside described follower gear two, screw rod two is installed, described screw rod two bottom mounting seat, described base bottom installed rows travelling wheel, described taking over a business is identical with described base, the top of taking over a business on described screw rod one is equal with the distance to described mounting platform bottom described road wheel to the distance of described mounting platform.This solid of revolution x-ray inspection device solves problem easily of focusing, but for longer pipeline, device is not easy to manually adjusting knob and regulates after entering pipe interior, therefore inapplicable with oversize tapered pipeline.
summary of the invention:
The object of the invention is to provide a kind of tapered pipeline x-ray inspection device for above-mentioned Problems existing, particularly for longer pipeline, be convenient to regulate focusing in the process detected.
Above-mentioned object is realized by following technical scheme:
Tapered pipeline x-ray inspection device, comprise walking dolly, by screw rod one connecting screw rod cover on described walking dolly, described screw sleeve connects circumferential radiation x-ray flaw detector by support, the center of described screw sleeve and described circumferential radiation x-ray flaw detector is on same horizontal line, there is inside described screw sleeve the internal thread that two sections of directions are contrary, described screw sleeve top connects top contact block by screw rod two, described screw rod one is equal with the length of described screw rod two, described walking dolly is equal with the height of described top contact block, the both sides of described screw sleeve are wound with the contrary stay cord in direction.
Described tapered pipeline x-ray inspection device, described walking dolly is provided with CD-ROM drive motor.
Described tapered pipeline x-ray inspection device, described top contact block is provided with pressure-detecting device.
Beneficial effect:
1. the present invention only needs to rotate swivel nut in the process of detecting a flaw to tapered pipeline, make the top of the bottom of walking dolly and top contact block can push up the inwall of pipeline, then pipeline is put into, circumferential radiation x-ray flaw detector is kept to be in pipeline center, when advancing to the position of pipeline reducing diameter, pull corresponding stay cord to make screw sleeve rotate thus make screw sleeve to move or moves down from the outside, drive circumferential radiation x-ray flaw detector to be in pipeline center.
2. top of the present invention contact block is provided with pressure-detecting device, be convenient to the situation of the Data Detection reducing transmitted according to pressure-detecting device, pressure increase represents that internal diameter of the pipeline reduces, at this moment need rotary screw cover that device whole height is diminished, pressure reduces to represent that internal diameter of the pipeline is in increase, reverse operating.
