Description

Technical Field

[0001] This utility model relates to the field of container testing technology, and in particular to a comprehensive non-destructive testing device for pressure vessels. Background Technology

[0002] Pressure vessels are widely used in production and daily life fields such as machinery, petroleum, and chemical industries. They are one of the high-risk pressure-bearing special equipment. Currently, when inspecting pressure vessels, the pressure vessel is generally placed on a workbench, and the operator holds a test probe to perform non-destructive testing on the surface of the pressure vessel. This testing method is prone to missing areas, thus failing to ensure comprehensive coverage of the testing range and affecting the accuracy of the test results. This poses certain safety hazards to the pressure vessel during subsequent use.

[0003] Current technology (CN212658686U) discloses a non-destructive testing device for pressure vessels, comprising a base plate, U-shaped frames, and a collar. U-shaped frames are symmetrically mounted at both ends of the base plate, and a guide rod is horizontally fixed between the two U-shaped frames. Sliding sleeves are mounted on both sides of the collar, slidingly fitted onto the guide rod. A gear ring is rotatably embedded inside the collar, and a detection probe is mounted on the gear ring. A second motor is mounted on the outer wall of the collar, and a gear that meshes with the gear ring is mounted at the output end of the second motor. A translation mechanism that drives the collar to slide horizontally is also installed between the two side supports. A support frame for supporting the pressure vessel is provided on the base plate. This non-destructive testing device for pressure vessels drives the detection probe to translate and rotate circumferentially simultaneously through the translation mechanism, thereby achieving omnidirectional testing of the pressure vessel. It provides wide testing coverage, avoids blind spots, improves the accuracy of testing results, and ensures product quality.

[0004] However, the fixed position of the support frame in the above scheme limits the detection range of the collar and makes it impossible to detect some longer or shorter pressure vessels. Utility Model Content

[0005] The purpose of this invention is to provide a comprehensive non-destructive testing device for pressure vessels, which aims to solve the problem that the fixed position of the support frame in existing non-destructive testing devices for pressure vessels limits the testing range of the collar and makes it impossible to test some longer or shorter pressure vessels.

[0006] To achieve the above objectives, this utility model provides an all-around non-destructive testing device for pressure vessels, comprising a base plate and a testing assembly. The testing assembly includes a support member, a testing component, a clamping motor, a bidirectional threaded shaft, two moving blocks, two support columns, and two limiting components. The support member is disposed on one side of the base plate, and the testing component is disposed on one side of the support member. The clamping motor is fixedly connected to the base plate and located on one side of the base plate. The bidirectional threaded shaft is fixedly connected to the output end of the clamping motor and located on one side of the clamping motor. The two moving blocks are respectively threadedly connected to the bidirectional threaded shaft and slidably connected to the base plate, and are respectively located on one side of the bidirectional threaded shaft. The two support columns are respectively fixedly connected to the moving blocks and are respectively located on the top of the moving blocks. The two limiting components are respectively disposed on one side of the limiting component.

[0007] The supporting structure includes two supporting members, a drive motor, a drive screw, and a connecting shaft. The two supporting members are fixedly connected to the base plate and are located at both ends of the base plate. The drive motor is fixedly connected to the supporting member and is located on the side of the supporting member. The drive screw is fixedly connected to the output end of the drive motor and is located on one side of the drive motor. The connecting shaft is fixedly connected to the supporting member and is located between the two supporting members.

[0008] The detection component includes a movable part, a collar, a sliding block, and a detection part. The movable part is threadedly connected to the drive screw and is located on one side of the drive screw. The collar is fixedly connected to the movable block and is located on one side of the movable block. The sliding block is fixedly connected to the collar and slidably connected to the connecting shaft and is located on one side of the collar. The detection part is disposed on one side of the collar.

[0009] The detection unit includes a mounting base, a detection motor, a gear, a toothed belt, and a detection probe. The mounting base is fixedly connected to the collar and located on the outer surface of the collar. The detection motor is fixedly connected to the mounting base and located on one side of the mounting base. The gear is fixedly connected to the output end of the detection motor and located on one side of the detection motor. The toothed belt is slidably connected to the collar and meshes with the gear, and is located on one side of the collar. The detection probe is fixedly connected to the toothed belt and located on one side of the toothed belt.

[0010] The limiting component includes a cylinder, a sliding column, and a limiting member. The cylinder is fixedly connected to the support column and located on one side of the support column. The sliding column is fixedly connected to the output end of the cylinder and slidably connected to the support column and located on one side of the support column. The limiting member is fixedly connected to the sliding column and located on one side of the sliding column.

[0011] This utility model discloses an all-around non-destructive testing device for pressure vessels. The clamping motor rotates, and the rotation of the output end of the clamping motor drives the bidirectional threaded shaft to rotate. The rotation of the bidirectional threaded shaft causes two moving blocks to move within the base plate. The movement of the moving blocks causes two supporting columns to expand or converge to accommodate pressure vessels of different lengths. Then, by adjusting the height of the limiting member, the pressure vessel is placed on the limiting member. By adjusting different heights, pressure vessels of different sizes can be supported at the center position of the collar. After the pressure vessel is adjusted, the testing member moves horizontally on the supporting member to perform non-destructive testing on the pressure vessel. This solution solves the problem in existing non-destructive testing devices for pressure vessels where the support frame is fixed in position, thus limiting the testing range of the collar and making it impossible to test some longer or shorter pressure vessels.

[0018] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

Figure 2 This is a structural schematic diagram of the entire utility model from another perspective. Figure 3 This is a top view of the entire utility model. Figure 4 This is a cross-sectional view of the entire utility model.

[0020] This utility model provides an all-around pressure vessel non-destructive testing device, including a base plate 101 and a testing component 102. The testing component 102 includes a support member 103, a testing component 104, a clamping motor 105, a bidirectional threaded shaft 106, two moving blocks 107, two support columns 108, and two limiting components 109. The support member 103 includes two support members 110, a drive motor 111, a drive screw 112, and a connecting shaft 113. The testing component 104 includes a moving member 114, a collar 115, a sliding block 116, and a testing part 117. The testing part 117 includes a mounting base 118, a testing motor 119, a gear 120, a toothed belt 121, and a testing probe 122. The limiting components 109 include a cylinder 123, a sliding column 124, and a limiting component 125. The aforementioned solution solves the problem in existing pressure vessel non-destructive testing devices where the position of the support frame is fixed, thus limiting the testing range of the collar 115 and making it impossible to test some longer or shorter pressure vessels.

[0021] In this specific embodiment, the support member 103 is disposed on one side of the base plate 101, the detection member 104 is disposed on one side of the support member 103, the clamping motor 105 is fixedly connected to the base plate 101 and located on one side of the base plate 101, the bidirectional threaded shaft 106 is fixedly connected to the output end of the clamping motor 105 and located on one side of the clamping motor 105, two moving blocks 107 are respectively threadedly connected to the bidirectional threaded shaft 106 and slidably connected to the base plate 101, and are respectively located on one side of the bidirectional threaded shaft 106, two support columns 108 are respectively fixedly connected to the moving blocks 107 and are respectively located on the top of the moving blocks 107, two limiting members 109 are respectively disposed on one side of the limiting member 109, and are rotated by the clamping motor 105. The rotation of the output end of the clamping motor 105... The movement will cause the bidirectional threaded shaft 106 to rotate, and the rotation of the bidirectional threaded shaft 106 will cause the two moving blocks 107 to move within the base plate 101. The movement of the moving blocks 107 will cause the two support columns 108 to unfold or converge to accommodate pressure vessels of different lengths. Then, by adjusting the height of the limiting member 109, the pressure vessel is placed on the limiting member 109. By adjusting different heights, pressure vessels of different sizes can be supported at the center position of the collar 115. After the pressure vessel is adjusted, the detection member 104 moves horizontally on the support member 103 to perform non-destructive testing on the pressure vessel. Through the above solution, the problem that the position of the support frame is fixed in the existing pressure vessel non-destructive testing device, thus limiting the detection range of the collar 115 and making it impossible to test some longer or shorter pressure vessels is solved.

[0022] Two support members 110 are fixedly connected to the base plate 101 and located at both ends of the base plate 101. The drive motor 111 is fixedly connected to the support member 110 and located on the side of the support member 110. The drive screw 112 is fixedly connected to the output end of the drive motor 111 and located on one side of the drive motor 111. The connecting shaft 113 is fixedly connected to the support member 110 and located between the two support members 110. The two support members 110 are located at both ends of the base plate 101 as supports for the detection component 104. The support members 110 are supported by the connecting shaft 113. The drive motor 111 drives the drive screw 112, which is also located between the support members 110. The drive screw 112 rotates due to the output end of the drive motor 111. The rotation of the drive screw 112 causes the detection component 104 to move horizontally, thereby performing non-destructive testing on the pressure vessel.

[0023] Secondly, the movable component 114 is threadedly connected to the drive screw 112 and located on one side of the drive screw 112. The collar 115 is fixedly connected to the movable block 107 and located on one side of the movable block 107. The sliding block 116 is fixedly connected to the collar 115 and slidably connected to the connecting shaft 113, and located on one side of the collar 115. The detection part 117 is disposed on one side of the collar 115. The movable block 107 is fixed to the outer surface of the collar 115. The movable component 114 is threadedly connected to the drive screw 112 and located on one side of the collar. The other end of 115 is fixed with the sliding block 116, which slides on the connecting shaft 113. When the drive screw 112 rotates, it will drive the moving part 114 to move. Since one end of the collar 115 is restricted by the sliding block 116, the collar 115 cannot rotate with the moving part 114 in place. Therefore, it can only slide with the rotation of the drive screw 112. The sliding of the moving part 114 will drive the collar 115 to move horizontally. During the movement, the pressure vessel is subjected to non-destructive testing by the detection unit 117.

[0024] Meanwhile, the mounting base 118 is fixedly connected to the collar 115 and located on the outer surface of the collar 115; the detection motor 119 is fixedly connected to the mounting base 118 and located on one side of the mounting base 118; the gear 120 is fixedly connected to the output end of the detection motor 119 and located on one side of the detection motor 119; the toothed belt 121 is slidably connected to the collar 115 and meshes with the gear 120, and is located on one side of the collar 115; the detection probe 122 is fixedly connected to the toothed belt 121 and located on one side of the toothed belt 121; and the mounting base 118 is located on the surface of the collar 115. The detection motor 119 is fixed on the mounting base 118. The output end of the detection motor 119 is fixed to the gear 120. The gear 120 meshes with the toothed surface of the toothed belt 121 inside the collar 115. The detection motor 119 drives the gear 120 to rotate. The toothed belt 121 meshes with the gear 120. The rotation of the gear 120 causes the toothed belt 121 to slide inside the collar 115. The other end of the toothed belt 121 has the detection probe 122. Driven by the gear 120, the detection probe 122 continuously detects the surface of the pressure vessel to ensure the accuracy of the detection data.

[0025] In addition, the cylinder 123 is fixedly connected to the support column 108 and located on one side of the support column 108. The sliding column 124 is fixedly connected to the output end of the cylinder 123 and slidably connected to the support column 108 and located on one side of the support column 108. The limiting member 125 is fixedly connected to the sliding column 124 and located on one side of the sliding column 124. During debugging, the limiting member 125 supports and limits the pressure vessel. However, the pressure vessels being tested may be of different sizes. Without height adjustment, the different axes of the collar 115 may easily cause collisions. The output end of the cylinder 123 drives the sliding column 124 to rise and fall within the support column 108, thereby adjusting the height of the limiting member 125 supporting the pressure vessel, thus ensuring that the pressure vessel is always at the same central axis height of the collar 115.

[0026] In using this utility model, the clamping motor 105 rotates, and the rotation of the output end of the clamping motor 105 drives the bidirectional threaded shaft 106 to rotate. The rotation of the bidirectional threaded shaft 106 drives the two moving blocks 107 to move within the base plate 101. The movement of the moving blocks 107 drives the two support columns 108 to unfold or converge to accommodate pressure vessels of different lengths. Subsequently, the cylinder 123, the output end of which drives the sliding column 124 to rise and fall, thereby adjusting the support height of the limiting member 125. Then, the pressure vessel is placed on the limiting member 125. By adjusting different heights, pressure vessels of different sizes can be supported at the center position of the collar 115. After the pressure vessel is adjusted, the drive motor 111 drives the drive screw 112 to rotate, and the rotation of the drive screw 112 drives the collar 115 to move horizontally. The collar 115 has a mounting base 118 on its surface, and a detection motor 119 is fixed on the mounting base 118. The output end of the detection motor 119 is fixed with a gear 120. The gear 120 meshes with the toothed surface of the toothed belt 121 inside the collar 115. The detection motor 119 drives the gear 120 to rotate, and the toothed belt 121 meshes with the gear 120. The rotation of the gear 120 causes the toothed belt 121 to slide inside the collar 115. The other end of the toothed belt 121 has a detection probe 122. Driven by the gear 120, the detection probe 122 continuously detects the surface of the pressure vessel, ensuring the accuracy of the detection data. Through the above solution, the problem of the fixed position of the support frame in the existing pressure vessel non-destructive testing device, which limits the detection range of the collar 115 and makes it impossible to detect some longer or shorter pressure vessels, is solved.
