[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-4 This utility model provides a technical solution: a pressure-bearing special equipment inspection device, including a base 1, an installation plate 9 fixedly connected to one side of the top of the base 1, a second electric slide rail 15 fixedly installed on one side of the installation plate 9, a second slider 16 installed at the output end of the second electric slide rail 15, a third motor 17 fixedly installed on one side of the second slider 16, a gear 21 fixedly connected to the output end of the third motor 17, the end of the gear 21 away from the third motor 17 rotatably connected to the inside of the second slider 16, an arc-shaped rack 18 meshing with the tooth end of the gear 21, an arc-shaped plate 19 fixedly connected to the bottom of the arc-shaped rack 18, a second detection head 20 installed at both ends of the arc-shaped plate 19, an arc-shaped groove 22 opened on one side of the second slider 16, the outer wall of the arc-shaped plate 19 slidably connected to the arc-shaped groove 22 of the second slider 16, a fixed clamping structure installed on one side of the base 1, and an endoscopic detection structure fixedly installed on the other side of the installation plate 9.

[0029] Specifically, the pressure pipe or tank is clamped and fixed by a fixed clamping structure. The operation of the third motor 17 drives the gear 21 to rotate inside the second slider 16, thereby driving the arc-shaped rack 18 to rotate. This causes the arc-shaped plate 19 to slide within the arc-shaped groove 22 of the second slider 16, thereby causing the second detection head 20 to move around the pressure pipe or tank as the axis. The second detection head 20 then inspects the outer circumference of the pressure pipe or tank. The operation of the second electric slide rail 15 causes the second slider 16 to move horizontally within the second electric slide rail 15, thereby driving the arc-shaped plate 19 to move horizontally, and thus driving the second detection head 20 to move horizontally. This allows for a comprehensive inspection of the outer circumference of the pressure pipe or tank. The endoscopic inspection structure also inspects the interior of the pressure pipe or tank, providing a comprehensive inspection. This solves the problem of blind spots in traditional pressure-bearing special equipment inspection devices, which affect the efficiency of the inspection.

[0030] Please see Figure 1 , Figure 2 , Figure 4The fixed clamping structure includes a first motor 2, one side of which is fixedly mounted on one side of the base 1. The output end of the first motor 2 passes through one side of the base 1 and is fixedly connected to a first bidirectional lead screw 8. The end of the first bidirectional lead screw 8 away from the first motor 2 is rotatably connected to one side of the base 1. A moving block 3 is symmetrically threaded to the outer wall of the first bidirectional lead screw 8. A second motor 4 is fixedly mounted on one side of the moving block 3. A second bidirectional lead screw 23 is fixedly connected to the output end of the second motor 4. A clamping block 5 is symmetrically threaded to the outer wall of the second bidirectional lead screw 23. The bottom of the clamping block 5 is slidably connected to the top of the moving block 3. The bottom of the moving block 3 is slidably connected to the top of the base 1. A support seat 6 is fixedly connected to the top of the moving block 3. A ball bearing 7 is provided on the top of the support seat 6.

[0031] Specifically, the operation of the first motor 2 drives the first bidirectional lead screw 8 to rotate inside the base 1, thereby causing the two moving blocks 3 to move closer or further apart to accommodate pressure pipes or tanks of different lengths. The support base 6 supports the pressure pipes or tanks, facilitating the second detection head 20 to inspect their outer circumference. The operation of the second motor 4 drives the second bidirectional lead screw 23 to move closer or further apart inside the moving blocks 3, thereby clamping and fixing the pressure pipes or tanks at the top of the support base 6. The ball bearings 7 at the top of the support base 6 allow the first motor 2 to adjust the position of the moving blocks 3 according to the inspection requirements, facilitating the inspection of the pressure pipes or tanks and enhancing the practicality of the device.

[0032] Please see Figure 1 , Figure 2 The endoscopic detection structure includes a first electric slide rail 10, one side of which is fixedly mounted on the other side of the mounting plate 9. A first slider 11 is provided at the output end of the first electric slide rail 10. An electric push rod 12 is fixedly mounted on one side of the first slider 11. A connecting plate 13 is fixedly connected to the output end of the electric push rod 12. A first detection head 14 is installed on the side of the connecting plate 13 away from the electric push rod 12.

[0033] Specifically, the operation of the electric push rod 12 drives the connecting plate 13 to move, which in turn drives the first detection head 14 to move horizontally, thereby inspecting the inside of the pressure pipeline or tank. The operation of the first electric slide rail 10 drives the first slider 11 to move inside the first electric slide rail 10, which in turn drives the electric push rod 12 to move up and down, thereby driving the connecting plate 13 and the first detection head 14 to move up and down. This facilitates the inspection of the inside of pressure pipelines or tanks of different diameters, thus enhancing the applicability of this device.

[0034] Working principle: When using this device, the pressure pipe or tank is placed on the support base 6. The ball bearings 7 on the top of the support base 6 facilitate the movement of the first bidirectional lead screw 8 inside the base 1 via the first motor 2, thereby moving the two moving blocks 3 closer or further apart to adjust their position to accommodate pressure pipes or tanks of different lengths. Then, the second motor 4 drives the second bidirectional lead screw 23 to move inside the moving blocks 3, clamping and fixing the pressure pipe or tank at the top of the support base 6. Finally, the third motor 17 drives the gear 21 to rotate inside the second slider 16, causing the arc-shaped rack 18 and arc-shaped plate 19 to slide within the arc-shaped groove 22 of the second slider 16, thus moving the second detection head 20 over the pressure pipe or tank. The device moves along a central axis, while simultaneously driving the second slider 16 to move horizontally within the second electric slide rail 15. This, in turn, drives the arc plate 19 and the second detection head 20 to move horizontally, allowing the second detection head 20 to perform a comprehensive inspection of the outer circumference of the pressure pipe or tank. Then, the first slider 11 moves within the first electric slide rail 10, driving the electric push rod 12 to move up and down, which in turn drives the connecting plate 13 and the first detection head 14 to move up and down. Finally, the electric push rod 12 drives the connecting plate 13 to move, which in turn drives the first detection head 14 to move horizontally, thus inspecting the interior of the pressure pipe or tank. This facilitates the inspection of the interior of pressure pipes or tanks of different diameters.
