[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0035] A testing device for pressure-bearing equipment, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the device includes a base 10, which is fixedly placed on the ground. Two detection probes 21 are movably mounted on the base 10. A clamping structure is movably mounted on one side of the base 10. The clamping structure includes an electric forward / reverse lead screw 15, a slide bar 16, and a clamping plate 17. The electric forward / reverse lead screw 15 and the slide bar 16 are symmetrically arranged on the base 10, and the clamping plate 17 is slidably mounted on one side of the base 10. Figure 3As shown, the electric forward and reverse lead screw 15 and the slide bar 16 are symmetrically arranged with the first electric lead screw 14 as the center. There are two clamping plates 17, which are symmetrically arranged vertically. One end of the clamping plate 17 is threaded to the electric forward and reverse lead screw 15, and the other end of the clamping plate 17 is slidably engaged with the slide bar 16.

[0036] Specifically, this device features a clamping structure. The clamping plate 17 consists of an arc-shaped plate and two square plates. The two square plates are respectively located on both sides of the arc-shaped plate. Threaded holes and round holes are respectively opened in the two square plates. When the electric forward and reverse screw 15 is activated, the clamping plates 17 on the upper and lower sides slide up and down between the slide rod 16 and the electric forward and reverse screw 15, approaching the outer wall of the pipe to clamp and fix the outer wall of the pipe, helping to stabilize the pipe and avoid bumps and wear.

[0037] The support structure is slidably mounted on the base 10. The support structure includes a support plate 11, a retaining ring 29, and a support block 31. The support plate 11 is slidably mounted on the base 10, the support block 31 is movably mounted within the support plate 11, and the retaining ring 29 is fixedly mounted within the support plate 11. Figure 3 and Figure 6 As shown, the support plate 11 is a square plate structure, and it is slidably mounted on the inner bottom surface of the base 10. A square opening is provided inside the support plate 11, and a retaining ring 29 is fixedly installed inside the square opening. The retaining ring 29 passes through the square opening. A fixing ring 24 is fixedly installed at one end of the slide rail 20, and the fixing ring 24 rotates within the retaining ring 29. The support plate 11 is limited by the retaining ring 29 to position the fixing ring 24. Figure 6 As shown, there are two support blocks 31. Both support blocks 31 are L-shaped blocks. The left and right sides of the support blocks 31 are provided with arc surfaces corresponding to the pipe wall. A spring 30 is fixed between the support block 31 and the retaining ring 29. The pulley 19 is elastically connected to the support block 31 through the spring 30.

[0038] Specifically, this device, through the setting of a support structure, firstly, the pipe needs to pass through the moving block and be clamped and fixed by the clamping structure. Then, the cylinder 12 is activated to push the support plate 11 to slide on the inner wall of the base 10, close to the fixed end of the pipe. At this time, the slide rail 20 passes through the inside of the retaining ring 29, thus supporting the rotation of the slide rail 20 later. When the two support blocks 31 on both sides abut against the inner wall of the pipe, the diameter of the inner wall of the pipe automatically and synchronously squeezes the two support blocks 31 on both sides, squeezing the spring 30. Under the action of the spring 30, the two support blocks 31 on both sides can automatically adapt to the diameter of the inner wall of the pipe. The two clamping plates 17 are vertically clamped, while the two support blocks 31 are horizontally supported, realizing the support of the inner wall of the pipe, thereby stabilizing the pipe.

[0039] The detection structure is movably mounted on the base 10. The detection structure includes a movable detection structure and a surrounding detection structure. The movable detection structure includes a movable block 13, a first electric lead screw 14, a slide rail 20, a slider 22, and a second electric lead screw 23. The movable block 13 is slidably mounted on the base 10. The first electric lead screw 14 and the slide rail 20 are both rotatably mounted within the base 10. The second electric lead screw 23 is mounted within the slide rail 20, and the slider 22 is slidably mounted within the slide rail 20. The surrounding detection structure includes a pulley 19, an internal gear ring 25, a ring slide frame 27, a gear 28, and a belt 32. The pulley 19 is driven within the belt 32. The internal gear ring 25 is fixed within the movable block 13. The ring slide frame 27 slides around the movable block 13, and the gear 28 rotatably mounts within the ring slide frame 27. Figure 1 and Figure 2 As shown, the base 10 has an L-shaped structure. A cylinder 12 is fixedly installed on one side of the base 10. The output end of the cylinder 12 passes through one side of the base 10 and is connected to the wall of the support plate 11. The support structure and the clamping structure are symmetrically arranged at both ends inside the base 10. Figure 2 , Figure 4 and Figure 7 As shown, a groove 18 is formed on the inner bottom surface of the base 10. The first electric lead screw 14 is disposed in the groove 18, and the moving block 13 is slidably disposed in the groove 18. A cavity is formed on the side of the base 10 near the clamping structure. The pulleys 19 and the belt 32 are driven in the cavity. There are two pulleys 19, which are respectively fixedly connected to the first electric lead screw 14 and the slide rail 20. The two pulleys 19 drive the same belt 32. Figure 4 As shown, one end of the slide rail 20 is fixedly connected to the pulley 19, which is rotatably mounted within the base 10. The slider 22 is threadedly engaged with the second electric lead screw 23, and one of the detection probes 21 is fixedly mounted on the top surface of the slider 22. Figure 5 and Figure 7 As shown, the movable block 13 is threadedly engaged with the first electric lead screw 14. An internal gear ring 25 is fixedly installed inside the movable block 13, and a gear 28 meshes with the internal gear ring 25. Annular grooves are respectively formed on the curved surfaces of both sides of the movable block 13. The sliding frame 27 corresponds to the shape of the inner ring of the movable block 13 and the annular grooves. The sliding frame 27 has a U-shaped structure and slides around the inner ring of the movable block 13. Figure 5 and Figure 7 As shown, another detection probe 21 is fixedly installed on the side of the ring slide 27 near the circular side of the moving block 13. A motor 26 is fixedly installed on one side plane of the ring slide 27. The output end of the motor 26 passes through the ring slide 27 and is connected to one side of the gear 28.

[0040] Specifically, this device employs a detection structure. The first electric lead screw 14 and the second electric lead screw 23 have similar structures but different sizes. Both consist of a drive motor and a lead screw. A pulley 19 is fixedly mounted on one curved surface of the first electric lead screw 14 and on one side of the slide rail 20. Both are driven by the same belt 32. The rotation of the first electric lead screw 14 synchronizes the rotation of the slide rail 20, causing the second electric lead screw 23 and the slider 22 within the slide rail 20 to rotate accordingly. In use, first ensure the pipe is securely fixed, then start the motor 26, then start the second electric lead screw 23, and finally start the first electric lead screw 14. Following this sequence, when the first… When the electric lead screw 14 is started, the moving block 13 drives the connected ring slide 27, motor 26 and gear 28 to move horizontally. At the same time, the slide rail 20 rotates. Simultaneously, the motor 26 drives the gear 28 to mesh with the internal gear ring 25, so that the ring slide 27 drives the connected detection probe 21 to rotate around the outer wall of the pipe for detection. Simultaneously, the second electric lead screw 23 drives the slider 22 to move horizontally within the slide rail 20. At this time, the detection probe 21 connected to the slider 22 rotates in the center of the pipe. By using uniform movement and smooth circling motion, the two detection probes 21 can simultaneously detect the inner and outer walls of the pipe, ensuring that every part is detected evenly and avoiding the occurrence of detection dead zones.
