Detailed implementation manners

[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners. The invention of the present invention is given for the purpose of illustration and description, and is not exhaustive or limited to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The invention is selected and described to better illustrate the principles and practical applications of the present invention, and enable those of ordinary skill in the art to understand the present invention and thus design various inventions suitable for specific purposes with various modifications.

[0028] Please refer to Figures 1 to 8, a nondestructive testing device for special equipment installation is provided in the present invention, including a fixed seat 1 and a side plate 2. On the upper end face of the fixed seat 1, a U-shaped seat 11 is installed. On the upper end face of the U-shaped seat 11, an adjusting cylinder 12 is installed. The output end of the adjusting cylinder 12 is installed with an upper cavity 13. On the left end face of the inner side of the upper cavity 13, a first lead screw 14 is rotatably installed through a bearing. On the outer side wall of the first lead screw 14, first sliders are symmetrically screwed on the left and right. The bottom of the first slider is installed with a side plate 2. On the front end face of the side plate 2, a first scale 15 is installed. On the front end face of the upper cavity 13, a second scale 16 is installed. The left and right symmetric thread directions of the first lead screw 14 are opposite. During work, place the pressure vessel on the fixed seat 1, extend the side plate 2 into the pressure vessel, start the adjusting motor, drive the upper cavity 13 to move downwards, so that the bottom of the side plate 2 abuts against the inner bottom of the pressure vessel. Through the first scale 15, the height of the pressure vessel can be detected and processed. Drive the first lead screw 14 to rotate, so that the side plate 2 moves outwards and abuts against the inner side wall of the pressure vessel, so that the diameter of the inner side wall of the pressure vessel can be detected and processed, and then judge whether the production of the pressure vessel meets the standard.

[0029] An arc-shaped plate 17 is installed on the outer end face of the side plate 2. A first motor 18 is installed on the right end face of the first lead screw 14. During work, the arc-shaped part of the arc-shaped plate 17 can closely adhere to the inner side wall of the pressure vessel, and the first motor 18 can drive the first lead screw 14 to rotate.

[0030] Sliding holes are symmetrically opened at the front and rear of the inner end of the side plate 2. A connecting frame 19 is installed in the sliding holes by means of sliding fit. An outer plate 21 is installed on the outer end of the connecting frame 19. During work, the outer plate 21 fits on the upper end face of the pressure vessel, so as to facilitate judging the value of the first scale 15 through the outer plate 21 and accurately measuring the height of the pressure vessel.

[0031] A front position hole is opened on the front end face of the side plate 2. A first guiding needle 22 is installed on the front end face of the connecting frame 19. The front position hole passes through the first guiding needle 22. During work, the value of the first guiding needle 22 on the first scale 15 plays a guiding role.

[0032] A plurality of first pressure sensors 23 are embedded in the outer end of the arc-shaped plate 17 from top to bottom. A first warning lamp 24 is installed on the outer end of the U-shaped seat 11. A control panel 25 is arranged below the first warning lamp 24. The first pressure sensors 23 and the first warning lamp 24 are electrically connected to the control panel 25. During work, a PLC program is written in the control panel 25 to control the operation of each device. When the arc-shaped plate 17 closely adheres to the inner side wall of the pressure vessel, when all the first pressure sensors 23 sense pressure, the first warning lamp 24 lights up to ensure the close adhesion effect of the arc-shaped plate 17 on the inner side wall of the pressure vessel, and further guarantee the accuracy of the diameter detection of the pressure vessel.

[0033] A second pressure sensor 26 is embedded at the bottom of the side plate 2, and a second warning light 27 is arranged in front of the first warning light 24. The second pressure sensor 26 and the second warning light 27 are both electrically connected to the control panel 25. During operation, when the side plate 2 abuts against the inner bottom of the pressure vessel, the second pressure sensor 26 senses the pressure, causing the second warning light 27 to light up, ensuring the pressing effect of the side plate 2 on the inner bottom of the pressure vessel, and thus guaranteeing the accuracy of the height detection of the pressure vessel.

[0034] A upper hole is opened on the front side end face of the upper cavity 13. A second guiding pin 28 is installed on the front side end face of the first slider. The second guiding pin 28 passes through the upper hole. During operation, the second guiding rod guides the second scale 16, facilitating the auxiliary judgment of the diameter of the pressure vessel.

[0035] Fixing frames 29 are symmetrically installed on the left and right side walls of the upper cavity 13. The other ends of the fixing frames 29 are connected to the inner ends of the C-shaped seats 11 in a sliding fit manner. During operation, the structure of the fixing frames 29 is adopted to ensure the stability of the up and down movement of the upper cavity 13.

[0036] The fixed seat 1 is a cavity structure with a hollow interior. Electric sliders 291 are symmetrically installed on the left and right sides of the inner side wall of the fixed seat 1. A placement plate 292 is installed at the inner ends of the electric sliders 291. A limiting ring is installed on the upper end face of the placement plate 292. An annular hole 293 is opened on the upper end face of the fixed seat 1. The electric sliders 291 are linear guide rail slider structures, and the device is controlled to move linearly by driving the lead screw to rotate by a motor. During operation, the pressure vessel is placed in the limiting ring of the placement plate 292, and the electric sliders 291 are started. After the detection is completed, the placement plate 292 is controlled to move downward, facilitating the removal of the pressure vessel for replacement.

[0037] A support rod 294 is installed at the inner bottom of the fixed seat 1 in a sliding fit manner. A spring rod 295 is installed on the outer side wall of the support rod 294 by plugging. A connecting plate is installed on the right side end face of the spring rod 295, and the connecting plate is installed at the inner bottom of the fixed seat 1. During operation, the support rod 294 supports the bottom of the placement plate 292. By pressing the spring rod 295 outward, the support rod 294 can be driven to slide outward, thereby driving the placement plate 292 to move up and down.

[0038] During specific operation, the pressure vessel is placed on the fixed seat 1, the side plate 2 extends into the pressure vessel, the adjustment motor is started to drive the upper cavity 13 to move downward, so that the bottom of the side plate 2 abuts against the inner bottom of the pressure vessel. The height of the pressure vessel can be detected through the first scale 15. The first lead screw 14 is driven to rotate, so that the side plate 2 moves outward to abut against the inner side wall of the pressure vessel, thereby enabling the detection of the inner side wall of the pressure vessel, and further judging whether the production of the pressure vessel meets the standards.

[0039] Obviously, the described invention is only a part of the present invention, rather than the whole invention. All other inventions obtained by those of ordinary skill in the art and related fields based on the invention in the present invention without creative work shall fall within the scope of protection of the present invention. Structures, devices, and operation methods not specifically described and explained in the present invention shall be implemented by conventional means in the art without special instructions and limitations.
