Embodiment
The present invention provides a kind of nozzle inner wall bias exposure support frame (hereinafter referred to as support frame), can be by shown in Fig. 1
The source 8 of radiographic source is fixed in nozzle inner wall, makes its eccentric exposure suitable for ray detection.
As shown in Figure 2 to 4, support frame is provided with by top transverse slat 2, bottom transverse slat 3, Left-side support plate 1, Right side support
The frame structure that plate 4 is surrounded, is additionally provided with foot support 5；The fulcrum of described one end of foot support 5 is arranged on Left-side support plate 1
The left side, the extension that the fulcrum of the other end is connected through a screw thread is arranged on the right of Right side support plate 4.
Wherein, top transverse slat 2 offers first through hole 21, for the source 8 in fixed RF source；Correspondingly, in institute
State bottom transverse slat 3 and offer the second through hole 31, for the pipeline (source is sent to source position by pipeline) in fixed RF source etc..
Afterwards, screwed foot support 5 is stretched out into tensioning, support frame is fixed to tested nozzle inner wall.During operation, pass through source 8
Eccentric exposure is carried out in tested nozzle interior.
In this example, the compartment of terrain of top transverse slat 2 offers 3 φ 20mm first through hole 21, and bottom transverse slat 3 offers correspondence
3 φ 30mm the second through hole 31.Multigroup through hole is designed, suitable for different eccentric distances when being to detect.In theory
Multiple sources can be installed simultaneously；But generally, exposure point only needs one, therefore preferably use one group corresponding first
Through hole and the second through hole.
The example sizes of support frame everywhere are provided in Fig. 2~Fig. 4, for helping to understand its dress with source shown in Fig. 1
With relation, and not as the concrete restriction to part dimension.During practical application, source 8 is fixed by top transverse slat 2,
Source 8 is set to be located at the top (height residing for source 8 is higher than foot support 5) of foot support 5, to avoid 5 pairs of bats of foot support during exposure
The influence of tablet quality.
Using the extension of threaded connection in foot support 5, its length can be changed by rotation, to be adaptively fixed on
The nozzle inner wall of different size.It is preferred that, opened by spiral rotating, the inside diameter ranges of the applicable adapter of the present invention are 330mm
To 480mm, but not limited to this.
The material of critical piece (top transverse slat 2, bottom transverse slat 3, Left-side support plate 1, Right side support plate 4, foot support 5) is excellent
Elect stainless steel 0Cr18Ni9 as.To avoid foot support 5 from scratching workpiece in the contact site of itself and tested adapter, by all contacts
Point is wrapped up with the part of plastic pvc material.For example, the fulcrum at the two ends of foot support 5, each via three sunk screws 7,
It is mounted with corresponding anti-slip rubber first 6.
It is preferred that, the axiality of the same group of through hole 31 of first through hole 21 and second is not less than φ 0.05；It is each in frame structure
The perpendicularity on neighboring vertical surface is not less than 0.05；Each seamed edge falls blunt processing；Also taken at stainless steel surfaces annular knurl 9 on fulcrum
Reason.
In summary, it is flexible solid by screwed foot support 5 in nozzle inner wall of the invention bias exposure support frame
It is scheduled on nozzle inner wall, it is ensured that the safety to radiographic source is fixed, and secure support, it is to avoid come off danger；The present invention is simple in construction, behaviour
Make convenient and swift, cost of manufacture is cheap, the eccentric measurement exposed is more facilitated, accurately.
Although present disclosure is discussed in detail by above preferred embodiment, but it should be appreciated that above-mentioned
Description is not considered as limitation of the present invention.After those skilled in the art have read the above, for the present invention's
