Technical Field
[0001] The utility model relates to the technical field of weld detection, and particularly relates to a rotary film shooting device for RT ray detection. Background Art
[0002] After the pipe fittings are welded, in order to ensure the welding firmness, the welds need to be detected. When detecting the welds of pipe fittings, an RT ray film shooting instrument is often used. The quality of the welds is judged by observing the imaging of the RT ray film shooting instrument on the film. However, when detecting large pipe fittings, this structure test is very troublesome. It is necessary to manually adjust the positions of the RT ray film shooting instrument, the film and the lead plate continuously, and the test efficiency is very low. Moreover, radiation will inevitably be generated during the test of the RT ray film shooting instrument. Therefore, there are great safety hazards in the way of manually adjusting the position for a long time. Therefore, it is particularly important to design a rotary film shooting device for RT ray detection to solve the above problems. Summary of the Invention

The rotary seat is driven to rotate by a rotary driving mechanism, so as to automatically complete the adjustment of the positions of the RT ray film shooting instrument, the film and the lead plate, greatly improving the test efficiency. Moreover, since there is no need for manual adjustment, the safety performance is improved, and the practical performance is increased.
[0004] To solve the above technical problems, the utility model provides a rotary film shooting device for RT ray detection, which is characterized in that: it includes a base, a test outer seat body, a rotary seat, an RT ray film shooting instrument, a film and a lead plate. The test outer seat body and the rotary seat are both cylindrical. The inner diameter of the test outer seat body matches the outer diameter of the rotary seat. The rotary seat is rotationally connected in the test outer seat body under the action of a rotary driving mechanism. A plurality of groups of roller assemblies are further arranged in the test outer seat body on the front and rear sides of the rotary seat. The RT ray film shooting instrument is fixed on the inner wall of the rotary seat through a first bracket and rotates with it. The film and the lead plate are detachably installed on a fixing plate. The RT ray film shooting instrument is arranged opposite to the film and the lead plate on the fixing plate. The fixing plate is fixed on the inner wall of the rotary seat through a second bracket and rotates with it. The pipe fitting to be tested passes through a plurality of groups of roller assemblies horizontally in and out of the test outer seat body and is subjected to weld detection by the RT ray film shooting instrument.
[0005] Further: Each group of roller assemblies is composed of two rollers, and the two rollers are respectively connected to the left and right inner walls at the lower end of the test outer seat body through a fixing frame.
[0006] Furthermore: The rotation driving mechanism includes a servo motor, a driving gear, and an external gear ring arranged on one side of the rotating seat. The driving gear is installed on the top of the test outer seat body through a connecting frame. The servo motor is installed on the connecting frame. The driving gear is connected to the output shaft of the servo motor and rotates driven by it. A notch for the driving gear to pass through is opened at the top of the test outer seat body, and the lower end of the driving gear passes through the test outer seat body along the notch and meshes with the external gear ring.
[0007] Still further: The lead plate is fixed on the fixing plate by bolts. The bolts sequentially pass through the clamping pieces and are connected to the threaded holes on the fixing plate through the lead plate. The film is pressed on the lead plate by the clamping pieces.
[0008] After adopting the above structure, the beneficial effects of the present utility model are as follows:
