Detailed Description
The invention provides a support frame for eccentric exposure of the inner wall of a connecting pipe (hereinafter referred to as a support frame for short), which can fix a source 8 of a radiation source shown in fig. 1 on the inner wall of the connecting pipe, so that the support frame is suitable for eccentric exposure in radiation detection.
As shown in fig. 2 to 4, the support frame is provided with a frame structure surrounded by an upper transverse plate 2, a lower transverse plate 3, a left support plate 1 and a right support plate 4, and is also provided with a foot support 5; the fulcrum of one end of the foot support 5 is arranged on the left side of the left side support plate 1, and the fulcrum of the other end is arranged on the right side of the right side support plate 4 through an extension section in threaded connection.
Wherein, the upper transverse plate 2 is provided with a first through hole 21 for fixing the source 8 of the radio frequency source; correspondingly, a second through hole 31 is formed in the lower cross plate 3, and a pipe for fixing a radio frequency source (the source is sent to a source position through the pipe), and the like. After that, the threaded foot support 5 is stretched out and tensioned, and the support frame is fixed on the inner wall of the measured connecting pipe. During operation, eccentric exposure is carried out inside the measured connecting pipe through the source 8.
In this example, the upper cross plate 2 is provided with 3 first through holes 21 of 20mm in diameter at intervals, and the lower cross plate 3 is provided with corresponding 3 second through holes 31 of 30mm in diameter. Multiple groups of through holes are designed to be suitable for different eccentric distances during detection. Theoretically, a plurality of sources can be installed at the same time; but in general only one exposure spot is required, so it is preferred to use a corresponding set of first and second vias.
Exemplary dimensions of the support bracket are provided throughout fig. 2-4 to aid in understanding its assembly relationship with the source shown in fig. 1, and are not intended to be limiting as to the size of the components. During practical application, the source 8 is fixed through the upper transverse plate 2, so that the source 8 is positioned on the upper portion of the foot support 5 (the height of the source 8 is higher than that of the foot support 5), and the influence of the foot support 5 on the quality of a film during exposure is avoided.
The foot support 5 adopts a threaded extension section, and the length of the foot support can be changed by rotation so as to be adaptively fixed on the inner wall of a connecting pipe with different specifications. Preferably, the inner diameter of the joint pipe to which the present invention is applied ranges from 330mm to 480mm by screw rotation opening, but is not limited thereto.
The material of the main components (upper cross plate 2, lower cross plate 3, left side support plate 1, right side support plate 4, foot bracket 5) is preferably stainless steel 0Cr18Ni9. In order to avoid the foot support 5 from scratching the workpiece at the contact point with the pipe to be tested, all the contact points are wrapped with plastic PVC material parts. For example, at the fulcra of the two ends of the foot support 5, respective anti-slip rubber heads 6 are mounted by three countersunk screws 7, respectively.
Preferably, the coaxiality of the first through holes 21 and the second through holes 31 in the same group is not lower than phi 0.05; the verticality of each adjacent vertical surface in the frame structure is not lower than 0.05; each edge is subjected to blunting treatment; the fulcrum is also treated by stainless steel surface knurling 9.
In summary, in the eccentric exposure support frame for the inner wall of the connecting pipe, the foot support 5 with threads is telescopically fixed on the inner wall of the connecting pipe, so that the safe fixation and the reliable support of the radiation source are ensured, and the falling danger is avoided; the invention has simple structure, convenient and quick operation and low manufacturing cost, and ensures that the eccentric exposure measurement is more convenient and accurate.
While the present invention has been described in detail through the foregoing description of the preferred embodiment, it should be understood that the foregoing description is not to be considered as limiting the invention. Many modifications and substitutions of the present invention will become apparent to those of ordinary skill in the art upon reading the foregoing. Accordingly, the scope of the invention should be limited only by the attached claims.
