DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand: the present invention is further explained below in conjunction with specific implementation methods.

[0023] like Figures 1 to 7As shown, the present invention provides a technical solution: a special equipment detection auxiliary positioning device, comprising a workbench 1, a placing table 2 is fixedly installed on the top of the workbench 1, a pressure vessel 3 is placed on the top of the placing table 2, clamping components are arranged on both sides of the pressure vessel 3, the clamping components clamp and position the pressure vessel 3 before detection, a detection instrument 4 is arranged above the pressure vessel 3, a moving component is arranged outside the detection instrument 4, the moving component is used to drive the detection instrument 4 to move, and detect the outer wall surface of the pressure vessel 3, two groups of linkage components are arranged between the clamping component and the moving component, the linkage component is used to drive the pressure vessel 3 to rotate, so that the undetected area of ​​the pressure vessel 3 is rotated to the bottom of the detection instrument 4 for detection.

[0024] During operation: When the existing device detects the pressure vessel, it is often necessary to fix the pressure vessel and then detect the surface of the pressure vessel through the detection instrument. However, since the pressure vessels are mostly cylindrical, the detection probe cannot detect the entire outer wall surface of the pressure vessel at one time during the detection, and multiple detections are required in different areas. Therefore, after completing one detection, it is necessary to adjust the relative position of the pressure vessel and the detection probe to complete a comprehensive inspection of the pressure vessel. This not only prolongs the inspection period, but also increases the complexity and risk of the operation, affecting the accuracy and reliability of the detection results. Through the implementation example of this scheme, when it is used specifically, the pressure vessel 3 to be inspected is first placed on the top of the placement table 2, and the pressure vessel 3 to be inspected is clamped and positioned by the clamping assembly. In the initial state, the detection instrument 4 is located on one side above the pressure vessel 3. After positioning, the moving assembly is started, and the moving assembly will drive the detection instrument 4 to move from the left side above the pressure vessel 3 to the right side, and the pressure The outer wall surface of the container 3 is inspected for a circle close to 90 degrees. After the inspection is completed, the inspection instrument 4 will move from the right to the left, and at this time it will touch the linkage component on the right, so that the clamping component rotates 90 degrees, and the clamping component will drive the pressure vessel 3 to rotate 90 degrees, so that the pressure vessel 3 rotates the outer wall surface of the 90-degree circle that has not been inspected to the bottom of the inspection instrument 4. When the inspection instrument 4 is reset from right to left, the 90-degree area is inspected, and after the inspection is completed again, the inspection instrument 4 will continue to move from the left to the right, and at this time it will touch the linkage component on the left. The clamping component allows the pressure vessel 3 to rotate again 90 degrees according to the last rotation direction, so that the outer wall surface of the other 90-degree circle that has not been inspected rotates to the bottom of the inspection instrument 4. This cycle is repeated twice, and the entire 360-degree outer wall surface of the entire pressure vessel 3 is inspected, so that the inspection range of the inspection instrument 4 can cover the entire outer wall area of ​​the pressure vessel 3, achieving a comprehensive inspection effect.

[0025] like Figure 2 and Figure 4As shown, the clamping assembly includes two opening seats 6, the inner walls of the two opening seats 6 are rotatably connected with a bidirectional threaded rod 8, the outer walls of the bidirectional threaded rod 8 are symmetrically threadedly connected with an inner slider 7, the outer walls of the two inner sliders 7 are slidably connected to the inner walls of the opening seats 6, one end of the two bidirectional threaded rods 8 is fixedly connected with a motor 9, and one end of each inner slider 7 is fixedly connected with a plastic clamp 5.

[0026] During operation: when the pressure vessel 3 is placed directly above the placement table 2, the two motors 9 are started, and their output shafts will respectively drive the connected bidirectional threaded rods 8 to rotate. When the bidirectional threaded rods 8 rotate, the two inner sliders 7 will be driven to slide inside the opening seat 6, so that the two inner sliders 7 are close to each other until the two plastic clamps 5 completely wrap and clamp the outer wall of the pressure vessel 3. Then, the motor 9 is stopped. At this time, the two groups of plastic clamps 5 outside the pressure vessel 3 tightly wrap and clamp the pressure vessel 3, and the plastic clamps 5 are made of plastic, so the detection instrument 4 will not be affected by obstruction during scanning and detection.

[0027] like Figure 3 to Figure 4 As shown, the outer sides of the two bidirectional threaded rods 8 are each provided with an inner groove ring 11, and the inner walls of the inner groove rings 11 are symmetrically slidably connected with arc-shaped sliders 10 and adapted to each other, wherein one arc-shaped slider 10 is fixedly connected to the top of the motor 9, and the other arc-shaped slider 10 is rotatably connected to the top of the bidirectional threaded rod 8, and the bottoms of the two inner groove rings 11 are fixedly connected with tripods 12, and the two tripods 12 are placed on the top of the workbench 1.

[0028] During operation: whenever the detection instrument 4 completes the detection through the moving component, the opening seat 6 will rotate along the inside of the inner groove ring 11 through the linkage component, and the opening seat 6 will not be out of position when sliding along the inside of the inner groove ring 11 through the motor 9 and the arc-shaped slider 10 under the bidirectional threaded rod 8. When the opening seat 6 rotates, it will drive the plastic clamp 5 to rotate, thereby achieving the effect of driving the pressure vessel 3 to rotate, so that the undetected area of ​​the pressure vessel 3 can be directly under the detection instrument 4.

[0029] like Figures 5 and 6 As shown, the moving assembly includes a tilting fixed seat 25, the inner wall of the tilting fixed seat 25 is rotatably connected to a threaded rod 24, the outer wall of the threaded rod 24 is threadedly connected to an inner slider 23, the outer wall of the inner slider 23 is slidably connected to the inner wall of the tilting fixed seat 25 and is adapted to each other, one end of the threaded rod 24 is fixedly connected to a motor 26, the motor 26 is fixed on one side of the tilting fixed seat 25, the bottom of the inner slider 23 is fixedly connected to the top of the detection instrument 4, the top of the tilting fixed seat 25 is fixedly connected to a fixing frame 27, and the fixing frame 27 is fixedly installed on the top of the workbench 1.

[0030] During operation: after the pressure vessel 3 is fixed by the clamping assembly, the motor 26 is started, and its output shaft will drive the threaded rod 24 to rotate. When the threaded rod 24 rotates, it will drive the inner slider 23 to move from the left side above the pressure vessel 3 to the right side. During the movement of the inner slider 23, the detection instrument 4 will scan the 90-degree outer wall surface of the pressure vessel 3, thereby realizing the detection of the outer wall surface of the pressure vessel 3 close to a 90-degree circumference. When the inner slider 23 moves to the rightmost end of the inclined fixing seat 25, the motor 26 is used to move the inner slider 23 to the leftmost end of the inclined fixing seat 25 for the next round of detection.

[0031] like Figure 3 and Figure 5 As shown, a rack plate 33 is provided above the inner slider 23, and the linkage assembly includes two column gears 20. The teeth of the rack plate 33 are meshed with the teeth of the two column gears 20. The number of teeth of the rack plate 33 is one-fourth of the number of teeth of the two column gears 20. The bottoms of the two column gears 20 are fixedly connected with bevel gears 2 19. The teeth of the two bevel gears 2 19 are meshed with bevel gears 1 18. A transmission assembly is provided between the two bevel gears 18 and the opening seat 6. The transmission assembly makes the opening seat 6 rotate in the same manner as the bevel gear 18.

[0032] During operation: when the detection instrument 4 moves from left to right and the detection is completed, the detection instrument 4 will move from the right to the left. At this time, the rack plate 33 will mesh with the column gear 20 on the right, so that the column gear 20 on the right rotates 90 degrees, and the bevel gear 18 on the right is driven to rotate 90 degrees through the bevel gear 2 19. Since the opening seat 6 rotates in the same way as the bevel gear 18, the bevel gear 18 on the right will cause the opening seat 6 to rotate 90 degrees, thereby driving the pressure vessel 3 to rotate 90 degrees, and rotating the undetected outer wall surface to the bottom of the detection instrument 4. When the detection instrument 4 is reset from right to left, the 90-degree area is detected. After the detection is completed again, the detection instrument 4 will continue to move from the left to right. The rack plate 33 moves to the right side, at which time the rack plate 33 will mesh with the column gear 20 on the left, causing the column gear 20 on the left to rotate 90 degrees, and the bevel gear 18 on the left to rotate 90 degrees through the bevel gear 2 19. Similarly, the pressure vessel 3 continues to rotate 90 degrees, and the undetected outer wall surface is rotated to the bottom of the detection instrument 4. Among them, when the rack plate 33 is meshed with the two column gears 20, the rotation directions of the two column gears 20 are opposite, but after the meshing transmission of the bevel gear 2 19 and the bevel gear 1 18, the rotation directions of the two bevel gears 18 are always the same, so that the direction of rotation of the pressure vessel 3 is the same each time, avoiding the pressure vessel 3 from rotating the detected surface to the bottom of the pressure vessel 3.

[0033] like Figures 2 to 3As shown, the transmission assembly includes two connecting rods 17, the two connecting rods 17 are rotatably connected to the inner wall of one side of the inner groove ring 11, the two connecting rods 17 are fixedly connected to the outer walls of the two bevel gears 18, one end of the two connecting rods 17 is fixedly connected to the transmission ring 16, the outer walls of the two transmission rings 16 are fixedly connected to the transmission belts 15, the other ends of the two transmission belts 15 are transmission connected to the transmission ring 14, one end of the two transmission rings 14 are fixedly connected to the connecting rod 13, and the two connecting rods 13 are fixedly connected to the outer walls at the center of the two opening seats 6.

[0034] During operation: when the bevel gear 18 rotates, it will drive the transmission ring 2 16 to rotate. When the transmission ring 2 16 rotates, it will drive the transmission ring 14 to rotate through the transmission belt 15. The rotation of the transmission ring 14 will drive the opening seat 6 to rotate through the connecting rod 13, and the connecting rod 13 is connected to the center of the opening seat 6, so that the opening seat 6 can rotate along the inner wall of the inner groove ring 11.

[0035] like Figures 2 to 3 As shown, the outer walls of the two column gears 20 are rotatably connected with clamping parts 21, and the clamping parts 21 are fixedly installed on the top surface of the inner groove ring 11. The outer walls of the two connecting rods 13 are rotatably connected with clamping parts 22, and the clamping parts 22 are fixedly installed on the outer side of the inner groove ring 11.

[0036] During operation: the positions of the connecting rod 2 17 and the connecting rod 1 13 are fixed by the clamping member 1 21 and the clamping member 2 22 to improve the stability of the device during the transmission process.

[0037] like Figure 6 to Figure 7 As shown, the top of the inner slider 23 is fixedly connected with a sliding sleeve 28, the outer wall of the sliding sleeve 28 is symmetrically fixedly connected with a connecting piece 29, the tops of the two connecting pieces 29 are fixedly connected with a fixing seat 31, the inner walls of the two fixing seats 31 are provided with a sliding groove 32, the inner walls of the two sliding grooves 32 are slidably connected with an inner slider 35, a sliding rod 30 is fixedly connected between the two inner sliders 35, one end of the sliding rod 30 is fixedly connected to one end of a rack plate 33, and a magnetic component is arranged on one side of the rack plate 33, and the magnetic component is used to drive the rack plate 33 to move.

[0038] During operation: when the rack plate 33 moves from left to right first, the rack plate 33 will first mesh with the column gear 20 on the right side. When the rack plate 33 moves from right to left, the magnetic component will make the rack plate 33 and the inner slider 35 move to the right, and the inner slider 35 will move to the rightmost end inside the fixed seat 31. Therefore, when the rack plate 33 moves from right to left, it will not mesh with the column gear 20 on the right side, avoiding meshing with it, so that the pressure vessel 3 will immediately rotate and return to its original position. When the rack plate 33 moves to the middle position above the pressure vessel 3, The magnetic component will move the inner slider three 35 to the leftmost position inside the fixed seat 31. At this time, the rack plate 33 can mesh with the column gear 20 on the left when it is close to the column gear 20 on the left. Similarly, after the rack plate 33 meshes with the column gear 20 on the left, the magnetic component will move the inner slider three 35 to the rightmost end. When the rack plate 33 moves from left to right, it will not mesh with the column gear 20 on the left. When it reaches the middle position above the pressure vessel 3, the rack plate 33 is moved again to a position where it can mesh with the column gear 20 on the right through the magnet block three 38.

[0039] like Figure 6 to Figure 7 As shown, the magnetic assembly includes magnet block 2 37, magnet block 38 and magnet block 4 39. The bottoms of magnet block 2 37, magnet block 38 and magnet block 4 39 are fixedly connected with connecting frames 36. Connecting frames 36 are fixedly installed on the top surface of inclined fixing seat 25. The top of sliding rod 30 is fixedly connected with magnet block 1 34. The surfaces of magnet block 1 34 and magnet block 2 37 that are close to each other are of the same pole, the surfaces of magnet block 1 34 and magnet block 38 that are close to each other are of different poles, and the surfaces of magnet block 1 34 and magnet block 4 39 that are close to each other are of the same pole.

[0040] During operation: when the rack plate 33 is meshed with the right column gear 20 to rotate the pressure vessel 3 by 90 degrees, the magnet block 1 34 is close to the magnet block 2 37. Since the adjacent surfaces are of the same pole, the same poles repel each other, so that the magnet block 1 34 drives the inner slider 3 35 to move to the rightmost end inside the fixed seat 31. When the rack plate 33 moves from right to left, it will not mesh with the right column gear 20 again. When the rack plate 33 moves to the middle of the upper part of the pressure vessel 3, the magnet block 1 34 is close to the magnet block 3 38. Since the opposite poles attract each other, the magnet block 1 34 drives the inner slider 3 35 to move to the leftmost end inside the fixed seat 31. When the rack plate 33 moves from right to left, the inner slider 3 35 moves to the leftmost end inside the fixed seat 31. When the rack plate 33 moves from left to right, it will mesh with the column gear 20 on the left, causing the pressure vessel 3 to rotate 90 degrees again. After the rack plate 33 meshes with the column gear 20 on the left, the magnet block 1 34 approaches the magnet block 4 39. Since the adjacent surfaces are of the same polarity, the same poles repel each other, causing the magnet block 1 34 to drive the inner slider 35 to move to the rightmost end inside the fixed seat 31. When the rack plate 33 moves from left to right, it will not mesh with the column gear 20 on the left again. This process is repeated to avoid the situation where the column gear 20 continues to rotate immediately when resetting after the rack plate 33 meshes with the column gear 20 on one side, resulting in the pressure vessel 3 being reset before detection after rotation.

[0041] like Figure 1 As shown, a data panel 40 is fixedly installed on the top of the workbench 1 .

[0042] During operation: the data panel 40 is used to collect data obtained after each detection of the pressure vessel 3, and analyze whether the data report of the pressure vessel 3 is normal.

[0043] Working process: First, place the pressure vessel 3 to be inspected on the top of the placing table 2, start the two motors 9, and their output shafts will drive the connected bidirectional threaded rods 8 to rotate. When the bidirectional threaded rods 8 rotate, they will drive the two inner sliders 7 to slide inside the opening seat 6, so that the two inner sliders 7 are close to each other until the two plastic clamps 5 completely wrap and clamp the outer wall of the pressure vessel 3. Stop starting the motor 9. At this time, the two groups of plastic clamps 5 on the outside of the pressure vessel 3 tightly wrap and clamp the pressure vessel 3, and the plastic clamps 5 are made of plastic, so the detection instrument 4 will not be affected by obstruction during scanning and detection.

[0044] After the pressure vessel 3 is fixed by the clamping assembly, the motor 26 is started, and its output shaft drives the threaded rod 24 to rotate. When the threaded rod 24 rotates, it drives the inner slider 23 to move from the left side above the pressure vessel 3 to the right side. During the movement of the inner slider 23, the detection instrument 4 scans the 90-degree outer wall surface of the pressure vessel 3, thereby realizing the detection of the outer wall surface of the pressure vessel 3 close to a 90-degree circumference. When the inner slider 23 moves to the rightmost end of the inclined fixing seat 25, the motor 26 moves the inner slider 23 to the leftmost end of the inclined fixing seat 25 for the next round of detection.

[0045] When the detection instrument 4 moves from left to right and the detection is completed, the detection instrument 4 will move from the right to the left. At this time, the rack plate 33 will mesh with the column gear 20 on the right, so that the column gear 20 on the right rotates 90 degrees, and the bevel gear 18 on the right is driven to rotate 90 degrees through the bevel gear 2 19. Since the opening seat 6 rotates in the same way as the bevel gear 18, the bevel gear 18 on the right will cause the opening seat 6 to rotate 90 degrees, thereby driving the pressure vessel 3 to rotate 90 degrees, and rotating the undetected outer wall surface to the bottom of the detection instrument 4. When the detection instrument 4 is reset from right to left, the 90-degree area is detected. After the detection is completed again, the detection instrument 4 will continue to move from the left side. When the rack plate 33 is moved to the right side, the rack plate 33 will mesh with the column gear 20 on the left side, so that the column gear 20 on the left side rotates 90 degrees, and the bevel gear 18 on the left side is driven to rotate 90 degrees through the bevel gear 2 19. Similarly, the pressure vessel 3 continues to rotate 90 degrees, and the undetected outer wall surface is rotated to the bottom of the detection instrument 4. Among them, when the rack plate 33 is meshed with the two column gears 20, the rotation directions of the two column gears 20 are opposite, but after the meshing transmission of the bevel gear 2 19 and the bevel gear 1 18, the rotation directions of the two bevel gears 18 are always the same, so that the direction of rotation of the pressure vessel 3 is the same each time, avoiding the pressure vessel 3 from rotating the detected surface to the bottom of the pressure vessel 3.

[0046] When the rack plate 33 is meshed with the column gear 20 on the right side so that the pressure vessel 3 rotates 90 degrees, the magnet block 1 34 is close to the magnet block 2 37. Since the adjacent surfaces are of the same pole, the same poles repel each other, so that the magnet block 1 34 drives the inner slider 3 35 to move to the rightmost end inside the fixed seat 31. When the rack plate 33 moves from right to left, it will not mesh with the column gear 20 on the right side again. When the rack plate 33 moves to the middle of the upper part of the pressure vessel 3, the magnet block 1 34 is close to the magnet block 3 38. Since the opposite poles attract each other, the magnet block 1 34 drives the inner slider 3 35 to move to the leftmost end inside the fixed seat 31. When the rack plate 33 moves from right to left, The rack plate 33 meshes with the column gear 20 on the left, causing the pressure vessel 3 to rotate 90 degrees again. After the rack plate 33 meshes with the column gear 20 on the left, the magnet block 1 34 approaches the magnet block 4 39. Since the adjacent surfaces are of the same polarity, the same poles repel each other, causing the magnet block 1 34 to drive the inner slider 35 to move to the rightmost end inside the fixed seat 31. When the rack plate 33 moves from left to right, it will not mesh with the column gear 20 on the left again. This process is repeated to avoid the situation where the column gear 20 continues to rotate immediately after the rack plate 33 meshes with the column gear 20 on one side during resetting, resulting in the pressure vessel 3 being reset before detection after rotation.

[0047] Finally, the data panel 40 is used to collect data obtained after each detection of the pressure vessel 3 and analyze whether the data report of the pressure vessel 3 is normal.
