The self-positioning X-ray flaw detection device for the tapered pipeline 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 bearing sleeve; the centers of the screw sleeve and the circumferential radiation X-ray flaw detector are positioned on the same horizontal line; internal threads matched with the first screw are arranged inside the lower part of the screw sleeve; an inner spiral groove is formed in the upper part of the screw sleeve; the upper part of the screw sleeve is connected with a top contact rod; a hemispherical bulge matched with the inner spiral groove is arranged on the top contact rod; the spiral directions of the inner spiral groove and the internal threads at the lower part of the screw sleeve are opposite to each other, and the screw pitches are equal to each other. The axis position of the X-ray flaw detector on a tapered body can be automatically adjusted, and flaw detection is facilitated.
Description
technical field:
The present invention relates to a kind of device conical pipeline being carried out to carrying out flaw detection, be specifically related to the self-align x-ray inspection device of a kind of conical pipeline.
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 conical pipeline, its internal diameter, in continuous change, needs to regulate focusing at any time, rely on manual adjustments also not show, and longer pipeline patent CN201320535949 also cannot realize manual adjustments.
summary of the invention:
The object of the invention is to provide a kind of conical pipeline self-align x-ray inspection device for above-mentioned Problems existing, in the detection of conical pipeline, automatically can locate focusing, easy to use, detection efficiency is high.
Above-mentioned object is realized by following technical scheme:
The self-align x-ray inspection device of conical pipeline, 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 bearing holder (housing, cover), the center of described screw sleeve and described circumferential radiation x-ray flaw detector is on same horizontal line, described screw sleeve inside lower portions is the internal thread coordinated with described screw rod one, the top of described swivel nut bar is provided with inside spin groove, described connection top, screw sleeve top feeler lever, described top feeler lever is provided with the dome-type of described inside spin groove fit protruding, described inside spin groove is contrary with the internal thread hand of spiral of described screw sleeve bottom and pitch is equal.
The self-align x-ray inspection device of described conical pipeline, described walking dolly is provided with CD-ROM drive motor.
The self-align x-ray inspection device of described conical pipeline, the height of described screw rod one and described walking dolly only and equal the height of described top feeler lever.
The self-align x-ray inspection device of described conical pipeline, described walking dolly is provided with the anti-of circumferential radiation x-ray flaw detector and turns to pin.
The self-align x-ray inspection device of described conical pipeline, described walking dolly is provided with the track for described top feeler lever motion, described top feeler lever is provided with the card article being arranged in described track.
Beneficial effect:
The present invention is for the detection of conical pipeline, first adjust equipment, circumferential radiation x-ray flaw detector is made just in time to be in the vertical centred position of equipment, then the heavy caliber end of conical pipeline is placed on, in the process that walking dolly driving device entirety is advanced, caliber reduces gradually, top feeler lever is subject to the effect of the pressure of pipeline, in the process that top feeler lever is pressed down, dome-type projection is moved in the inside spin groove of screw sleeve, because top feeler lever can not rotary motion by fixing can only moving up and down in track, therefore in the process that presses down of top feeler lever dome-type protruding in the inside spin groove of screw sleeve athletic meeting drive screw sleeve to rotate, circumferential radiation x-ray flaw detector is driven to decline in the process that screw sleeve rotates and the convenient focusing in the center of equipment all the time.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention.
In figure: 1, walking dolly, 2, screw rod one, 3, screw sleeve, 4, bearing holder (housing, cover), 5, circumferential radiation x-ray flaw detector, 6, top feeler lever, 7, dome-type is protruding, 8, CD-ROM drive motor, 9, anti-ly turn to pin; 10, track; 11, card article.
