The base plate has a rectangular structure with its four corners machined into arc shapes. A detector is installed on the top of the base plate. A bracket with an "L"-shaped structure is fixedly connected to one side of the top of the base plate. A first servo motor is fixedly connected to the top of the bracket. A first gear is fixedly connected to the output end of the first servo motor, and a second gear is meshed with the outer wall of the first gear. The base plate has two outer cylinders with circular structures on its upper sides. The inner walls of the two outer cylinders are rotatably connected to inner cylinders via bearings. The two inner cylinders are also circular. The bottoms of the two outer cylinders are respectively fixedly connected to a base and a sliding plate.

The top of the outer cylinder near the first servo motor is fixedly connected to the top of the bracket. The inner walls of the two inner cylinders are threaded with multiple torsion bars. The ends of the multiple torsion bars are rotatably connected to clamps via bearings. The multiple clamps are arc-shaped. The outer walls of the two inner cylinders are fixedly connected with arc-shaped rubber pads.

[0009] As a further optimization of this technical solution, the outer wall of the slide of the special equipment inspection and testing device of this utility model is fixedly connected to a connecting plate. The connecting plate has an English "P" shaped structure. The inner wall of the connecting plate is threadedly connected to a threaded rod that is rotatably connected to the top side of the base plate through a bearing. One end of the threaded rod is fixedly connected to a second servo motor, and the second servo motor is fixedly connected to the top side of the base plate. The bottom of the slide is slidably engaged with a slide rail that is fixedly connected to the top of the base plate.

[0010] As a further optimization of this technical solution, the bottom plate of the special equipment inspection and testing device of this utility model is fixedly connected to two lifting plates, and the top of the two lifting plates is fixedly connected to a top plate.

[0026] Furthermore, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] Please see Figures 1 to 4 This utility model provides a specific technical implementation scheme for a special equipment inspection and testing device:

[0028] A special equipment inspection and testing device includes: a base plate 1, a detector 2, a bracket 3, a first servo motor 4, a first gear 5, a second gear 6, an inner cylinder 7, a base 8, a clamping plate 9, a torsion bar 10, an outer cylinder 11, a sliding plate 12, a connecting plate 13, a threaded rod 14, a slide rail 15, a second servo motor 16, a lifting plate 17, a top plate 18, a third servo motor 19, a lead screw 20, and a mounting plate 21. The base plate 1 has a rectangular structure with its four corners machined into arc shapes. The detector 2 is installed on the top of the base plate 1. The bracket 3 is fixedly connected to one side of the top of the base plate 1, and the bracket 3 has an "L" shape. The first servo motor 4 is fixedly connected to the top of the bracket 3. The output end of the first servo motor 4 is fixedly connected to the first gear 5, and the outer wall of the first gear 5 is meshed with the first gear. The base plate 1 has a second gear 6. Two outer cylinders 11 with circular structures are provided on the upper sides of both sides of the base plate 1. The inner walls of the two outer cylinders 11 are rotatably connected to inner cylinders 7 via bearings. Both inner cylinders 7 are circular. The bottoms of the two outer cylinders 11 are respectively fixedly connected to a base 8 and a sliding plate 12. The bottom of the base 8 is fixedly connected to the top of the base plate 1. The inner wall of the second gear 6 is fixedly connected to the outer wall of the inner cylinder 7 on the side closest to the first servo motor 4. The top of the outer cylinder 11 on the side closest to the first servo motor 4 is fixedly connected to the top of the bracket 3. The first servo motor 4 can drive the second gear 6 to rotate via the first gear 5, thereby causing the inner cylinder 7 to rotate along the outer wall of the outer cylinder 11. This changes the angle of the pipe to be inspected, allowing for the inspection of the pipe's appearance and weld marks.

[0029] Both inner cylinders 7 have multiple torsion bars 10 threadedly connected to their inner walls. The ends of the multiple torsion bars 10 are rotatably connected to clamping plates 9 via bearings. The clamping plates 9 are all arc-shaped, and their outer walls are fixedly connected to arc-shaped rubber pads. Twisting the torsion bars 10 can change the position of the clamping plates 9, thereby using the multiple clamping plates 9 to clamp and fix the pipe to be inspected. The rubber pads can increase the friction between the clamping plates 9 and the pipe to be inspected, thereby improving the stability during clamping. It should be noted that when the torsion bars 10 are twisted, the clamping plates 9 will rotate with the torsion bars 10. Therefore, it is necessary to manually limit the clamping plates 9 when twisting the torsion bars 10. Alternatively, a limiting rod can be used to movably connect the clamping plates 9 and the inner cylinder 7 through the inner cylinder 7 and be fixed to the outer wall of the clamping plates 9 to limit the movement path of the clamping plates 9. The specific method can be selected according to the actual use situation to meet the technical features of this case.

[0030] A connecting plate 13 is fixedly connected to the outer wall of the slide plate 12. The connecting plate 13 has a "P" shaped structure. The inner wall of the connecting plate 13 is threadedly connected to a threaded rod 14 that is rotatably connected to the top side of the base plate 1 via a bearing. One end of the threaded rod 14 is fixedly connected to a second servo motor 16, and the second servo motor 16 is fixedly connected to the top side of the base plate 1. The bottom of the slide plate 12 is slidably engaged with a slide rail 15 that is fixedly connected to the top of the base plate 1. The second servo motor 16 can change the position of the slide plate 12 on the surface of the slide rail 15 through the threaded rod 14, thereby changing the position of the two inner cylinders 7. At this time, pipes of different sizes to be inspected can be installed and fixed.

[0031] Two lifting plates 17 are fixedly connected to the top of the base plate 1, and a top plate 18 is fixedly connected to the top of the two lifting plates 17. A third servo motor 19 is fixedly connected to one side of the top of the top plate 18. A lead screw 20 is fixedly connected to the output end of the third servo motor 19. The two ends of the lead screw 20 are rotatably connected to the top of the top plate 18 through bearings. A mounting plate 21 is threadedly connected to the outer wall of the lead screw 20. The outer wall of the mounting plate 21 is fixedly connected to the outer wall of the detector 2. The lifting plates 17 can change the height of the top plate 18, thereby changing the overall height of the detector 2, so as to meet the usage of different types of detectors 2. The third servo motor 19 changes the position of the detector 2 through the lead screw 20, so as to perform all-round inspection of the pipeline to be inspected.

[0032] The top of the top plate 18 has a groove with a rectangular strip structure, and the lower part of the outer wall of the mounting plate 21 is slidably engaged with the groove on the top of the top plate 18; the groove can limit the detector 2 through the mounting plate 21, so that the detector 2 can only achieve simple reciprocating motion.

[0033] Specifically, the models of detector 2, first servo motor 4, second servo motor 16, and third servo motor 19 are not limited, as long as they meet the usage requirements. Furthermore, the type of data that detector 2 detects can be selected according to the actual detection situation. This case does not restrict the type of detection data, data transmission method, or installation structure, and all of these are existing well-known technologies, so they will not be elaborated on here. Those skilled in the art should interpret them broadly. Workers can install electric push rods inside the lifting plate 17 to give the lifting plate 17 lifting ability. The specific installation structure and the specific selection of the drive equipment are not limited, as long as they meet the technical features of this case. Those skilled in the art should interpret them broadly.

[0034] Specific implementation steps:

[0035] In use, the operator turns on the second servo motor 16, which drives the threaded rod 14 to rotate. The threaded rod 14 then changes the position of the slide plate 12 on the surface of the slide rail 15 via the connecting plate 13, thereby changing the position of the two inner cylinders 7. When the distance between the two inner cylinders 7 is appropriate, the second servo motor 16 is turned off. The operator then inserts the pipe to be inspected between the clamping plates 9 inside the two inner cylinders 7 and twists the torsion bar 10. The torsion bar 10 then changes the position of the clamping plates 9. After the clamping plates 9 fix the pipe to be inspected, the detector 2 can then be used to inspect the pipe. When it is necessary to change the angle of the pipe to be inspected, the operator turns on the first servo motor 4. The first servo motor 4 then drives the second gear 6 to rotate via the first gear 5, which in turn drives the inner cylinder 7 to rotate along the inner wall of the outer cylinder 11, thus changing the angle of the pipe to be inspected. Then, the third servo motor 19 drives the lead screw 20 to rotate, which in turn changes the position of the detector 2 via the mounting plate 21, so as to perform a comprehensive inspection of the pipe to be inspected.

[0036] In summary, this special equipment inspection and testing device features a first servo motor that drives a second gear via a first gear to rotate the inner cylinder along the outer cylinder. This allows for comprehensive inspection of the pipe under inspection after it has been fixed, including inspection of appearance and weld marks. It does not interfere with strength testing or other inspections requiring pipe fixation, thus significantly expanding the inspection range. The second servo motor, via a threaded rod and connecting plate, moves a sliding plate along the outer wall of a slide rail, changing the position between the two inner cylinders to accommodate pipes of different sizes, further enhancing its usability. The third servo motor, via a lead screw, drives the detector in reciprocating motion, and a lifting plate alters the detector's height. This allows for changing the detector's position, thus changing the inspection location of the pipe. Multiple inspections at different locations improve the accuracy of the data and ensure inspection quality. This invention, through improvements to the special equipment inspection and testing device, offers advantages such as the ability to change the angle of the pipe under inspection, fix pipes of different sizes, and perform multiple inspections at different locations, effectively solving the problems and shortcomings of existing devices.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
