Description
Technical field：
The present invention relates to a kind of device that carrying out flaw detection is carried out to conical pipeline, and in particular to a kind of conical pipeline is with making by oneself
Position x-ray inspection device.
Background technology：
X-ray inspection, industrially has a very wide range of applications, and it is both used for metal inspection, is also used for nonmetallic inspection
Look into.X-ray flaw detector is divided to two kinds of directed radiation, circumferential radiation.Directed radiation is fixed, and beam radiation coning angle typically exists
40 °~45 ° scopes.Circumferential radiation beam is being penetrated into X is radiated on 360 ° of circumference of vertical direction simultaneously with X-ray tube axis
Line, this can complete the spy of whole weld seam by single exposure for detection large-caliber pipe fittings and the circular weld of spherical container
Wound photograph work, thus can greatly improve detection efficiency.
Generally needed from circumferential radiation x-ray flaw detector, existing circumferential radiation X-ray for the detection of metallic conduit
Defectoscope requires that defectoscope needs to be placed on pipeline the inside in the course of the work, and requires that radiographic source can inside revolving body
Accurate focusing, this sets different support focusings for the pipeline of reducing, in practical operation and bothers very much, causes detection to be imitated
Rate is low.
In order to solve the above problems, Chinese patent CN201320535949 discloses a kind of revolving body x-ray inspection device,
It includes mounting platform, and circumferential radiation x-ray flaw detector is installed on described mounting platform, and described circumferential radiation X-ray is visited
The radiation center for hindering machine is located at the center of described mounting platform, and adjusting knob is provided with described mounting platform, described
The coaxially connected driving gear of adjusting knob, described driving gear is engaged with driven gear one, described driven gear one with from
Moving gear two is engaged, and screw rod one is installed in the inside of described driven gear one, and the described top of screw rod one installs, it is described from
Screw rod two is installed in the inside of moving gear two, and road wheel is installed in the described bottom mounting seat of screw rod two, described base bottom, described
The top taken over a business taken over a business on screw rod one identical with described base, described to described mounting platform distance with it is described
Road wheel bottom to described mounting platform distance it is equal.It is convenient that the revolving body x-ray inspection device solves focusing
Problem, but for conical pipeline more long, its internal diameter is being continually changing, it is necessary to regulation focusing at any time, is adjusted by manual
Do not it has been shown that, and patent CN201320535949 cannot also realize regulation manually for pipeline more long.
The content of the invention：
The purpose of the present invention is directed to a kind of conical pipeline of above-mentioned problem offer and is filled with self-positioning x-ray inspection
Put, in the detection of conical pipeline, focusing can be automatically positioned, easy to use, detection efficiency is high.
Above-mentioned purpose is realized by following technical scheme：
Conical pipeline self-positioning x-ray inspection device, including walking dolly, pass through screw rod one on described walking dolly
Connecting screw rod set, circumferential radiation x-ray flaw detector is connected on described screw sleeve by bearing holder (housing, cover), described screw sleeve with it is described
Circumferential radiation x-ray flaw detector center on same horizontal line, described screw sleeve inside lower portions are and described spiral shell
The internal thread that bar one coordinates, the top of described swivel nut bar is provided with inside spin groove, described screw sleeve top connection top
Feeler lever, is provided with the dome-type projection with described inside spin groove fit on described top feeler lever, described inside spin is recessed
Groove is opposite with the internal thread hand of spiral of described screw sleeve bottom and pitch is equal.
Described conical pipeline is provided with drive motor with self-positioning x-ray inspection device on described walking dolly.
Described conical pipeline with self-positioning x-ray inspection device, the height of described screw rod one and described walking dolly
Degree is only and equal to the height of described top feeler lever.
Described conical pipeline is provided with circumferential radiation X and is penetrated with self-positioning x-ray inspection device on described walking dolly
The anti-steering pin of line defectoscope.
Described conical pipeline is provided with for described with self-positioning x-ray inspection device on described walking dolly
The track of top feeler lever motion, is provided with the card article in described track on described top feeler lever.
Beneficial effect：
The present invention first adjusts equipment so that circumferential radiation x-ray flaw detector is exactly in for the detection of conical pipeline
The vertical centred position of equipment, is then placed on the heavy caliber end of conical pipeline, in the mistake that walking dolly driving device is integrally advanced
Cheng Zhong, caliber is gradually reduced, and top feeler lever is subject to the pressure of pipeline to act on so that top feeler lever push during dome-type
Projection is moved in the inside spin groove of screw sleeve, and fortune can not be rotated because top feeler lever can only be moved up and down by fixation in track
It is dynamic, therefore the athletic meeting in the inside spin groove of screw sleeve of dome-type projection drives screw sleeve rotation during top feeler lever is pushed
Turn, screw sleeve drives circumferential radiation x-ray flaw detector to decline during rotating and the center of equipment is conveniently focused all the time.
