[0023] Specifically, the first motor 10 drives the first screw 9 to rotate, and the rotation of the first screw 9 causes the L-shaped seat 7 to slide inside the adjusting groove 8. The L-shaped seat 7 drives the moving platform 5 to move, making it easier to move the moving platform 5 to one side of the fixed frame 2 and the pressure plate 4. This facilitates the use of hoisting equipment to hoist the special equipment, avoiding the need for people to lift and move the special equipment, saving manpower, and improving its practicality.

[0024] Please see Figures 1-3 The adjustment mechanism includes a second motor 11 and a third motor 12. A rotating seat 13 is rotatably connected to the fixed frame 2. The second motor 11 is fixedly installed at the top of the fixed frame 2, and its output end is fixedly connected to the top of the rotating seat 13. A first sliding groove 14 is provided at the bottom of the rotating seat 13. A first sliding block 15 is slidably arranged inside the first sliding groove 14.

The bottom of the first sliding block 15 is fixedly connected to the top of the first hydraulic cylinder 3, which facilitates the adjustment of the position of the pressure plate 4 and facilitates pressure detection at different positions on special equipment.

[0025] Specifically, the second screw 16 is driven to rotate by the third motor 12. The rotation of the second screw 16 causes the first slide block 15 to slide inside the first slide groove 14. The first slide block 15 drives the first hydraulic cylinder 3 and the pressure plate 4 to move. At the same time, the second motor 11 drives the rotating seat 13 to rotate, which facilitates the adjustment of the position of the pressure plate 4. This allows the pressure plate 4 to be adjusted to the position on the special equipment where pressure testing is required, and facilitates pressure testing at different positions on the special equipment.

[0026] Please see Figure 5 The clamping mechanism includes a fourth motor 18. A fixed base 19 is fixedly connected to the top of the moving table 5. A second slide groove 20 is provided on the side of the fixed base 19. A bidirectional screw 21 is rotatably connected inside the second slide groove 20. Two second slide seats 22 are symmetrically threaded on the outside of the bidirectional screw 21. Both second slide seats 22 slide in sliding engagement with the second slide groove 20.

The two second slides 22 respectively drive the two clamping plates 23 to move, thereby clamping and fixing the special equipment. By adjusting the distance between the two clamping plates 23, it is convenient to clamp and fix special equipment of different sizes. The shape and size of the clamping plates 23 can be designed according to actual usage requirements.

[0028] Please see Figures 1-3 The fixed frame 2 is equipped with a protective cover 25 that slides on its exterior.

The telescopic end of the second hydraulic cylinder 28 is fixedly connected to the top of the fixed frame 2. The fixed frame 2 is provided with two notches 29. Two sliding plates 30 are fixedly connected to the protective cover 25. The two sliding plates 30 slide and engage with the two notches 29 respectively to ensure that the protective cover 25 slides up and down stably.

[0029] Specifically, before pressure testing the special equipment, the second hydraulic cylinder 28 drives the top plate 27 and the protective cover 25 to move downwards, and the bottom end of the protective cover 25 contacts the top end of the moving platform 5. The protective cover 25 covers the special equipment to be pressure tested, thus preventing residue from splashing during pressure testing and avoiding injury to the staff from the splashed residue.

[0030] In summary, when using the overall equipment: The first motor 10 drives the first screw 9 to rotate, causing the L-shaped seat 7 to slide inside the adjusting groove 8. The L-shaped seat 7 moves the moving platform 5 to one side of the fixed frame 2 and pressure plate 4. Then, the special equipment is hoisted onto the moving platform 5 by the hoisting equipment. The fourth motor 18 drives the bidirectional screw 21 to rotate, causing the two second slides 22 to move towards the middle. The two second slides 22 respectively drive the two clamping plates 23 to move, clamping and fixing the special equipment. Then, the first motor 10 is started, moving the moving platform 5 to the rearmost side. Then, the second hydraulic cylinder 28 drives the top plate 27 and the anti-collision plate 4 to move. The protective cover 25 moves downwards, bringing its bottom end into contact with the top of the moving platform 5. The protective cover 25 covers the special equipment to be pressure tested. The third motor 12 drives the second screw 16 to rotate, causing the first slide block 15 to slide inside the first slide groove 14. The first slide block 15 drives the first hydraulic cylinder 3 and the pressure plate 4 to move. At the same time, the second motor 11 drives the rotating seat 13 to rotate, adjusting the pressure plate 4 to the position on the special equipment where pressure testing is required. Then, the first hydraulic cylinder 3 pushes the pressure plate 4 downwards, pressing the special equipment to perform pressure testing.
