Description

Technical Field

[0001] This utility model relates to the field of storage tank testing technology, and in particular to a storage tank wall thickness testing device. Background Technology

[0002] In industries such as petroleum and chemical engineering, storage tanks are important equipment for storing liquids or gases. The uniformity and integrity of the tank wall thickness are crucial for the safe operation of the tank. However, due to the long-term effects of media corrosion, pressure changes and other factors, the wall thickness of the tank may change, and defects such as local thinning or perforation may even occur. Therefore, it is of great significance to regularly inspect the tank wall thickness and promptly identify and deal with potential safety hazards to ensure the safe operation of the tank.

[0003] A search revealed a Chinese patent with publication number CN207923080U, which provides an ultrasonic device for measuring the wall thickness of storage tanks. During measurement, impurities on the surface of the storage tank are knocked off by a striking cylinder, and then the temperature of the tank wall is measured by the inspector. The appropriate probe can be replaced in time. It is easy to operate and is used for the detection of the wall thickness of atmospheric pressure storage tanks.

[0004] However, during use, it was found that the measurement error was large when using the handheld device to detect the wall thickness of the storage tank, which affected the detection accuracy. For large storage tanks or storage tanks that need to be tested in multiple parts, the operation is not convenient and the detection efficiency is low, which is not conducive to the detection of storage tank wall thickness. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a tank wall thickness detection device. The straight probe of the ultrasonic thickness gauge body is abutted against the outer wall of the tank. By emitting and receiving ultrasonic signals, the wall thickness of the tank is measured, avoiding the shaking and errors caused by hand operation and improving detection accuracy. The rotating component and detection component adapt to the needs of tank wall thickness detection at different heights and angles, thus improving detection efficiency.

[0006] To solve the above technical problems, the present invention provides the following technical solution: a tank wall thickness detection device, comprising a connecting block, two clamping blocks on the connecting block, a rotating component mounted on the top surface of the clamping block, a slider fixed on one of the clamping blocks, a sliding groove on the connecting block, the outer wall of the slider being slidably connected to the groove wall, a slide rail fixed on the top surface of the connecting block, and a detection component slidably connected on the slide rail;

[0007] The detection component includes a movable block, the lower end of which is slidably connected to the outer wall of the slide rail and the top surface of the connecting block, the upper end of which is slidably connected to a push block, the top surface of which is fixedly provided with a support block, the upper end of which is rotatably connected to a rotating shaft, and a rotating block is fixedly provided on the rotating shaft. An ultrasonic thickness gauge body is installed on one side of the outer wall of the rotating block, and a straight probe is electrically connected to the ultrasonic thickness gauge body. The straight probe is installed on the rear wall of one end of the rotating block.

[0008] Preferably, a rubber roller is rotatably connected inside the clamping block, and a first servo motor is mounted on the rear wall of the clamping block via a mounting base, with the output shaft of the first servo motor coaxially connected to the rubber roller.

[0009] The above technical solution uses the output shaft of the first servo motor to drive the rubber roller to rotate. By utilizing the friction between the rubber roller and the outer wall of the storage tank, the entire detection device can move up and down on the outer wall of the storage tank, thereby adjusting the detection height.

[0010] Preferably, a first lead screw is rotatably connected inside the connecting block, a second servo motor is installed on the side wall of the connecting block, the output shaft of the second servo motor is coaxially connected to the first lead screw, and the middle part of the slider is threadedly connected to the first lead screw through a threaded hole.

[0011] The above technical solution uses a second servo motor to drive the first lead screw to rotate, causing the slider to slide in the groove, thereby adjusting the distance between the two clamping blocks to accommodate storage tanks of different diameters.

[0012] Preferably, the upper end of the connecting block is provided with a second lead screw, the moving block is threadedly connected to the second lead screw through a threaded hole, and a third servo motor is mounted on the connecting block through a mounting base, the output shaft of the third servo motor being coaxially connected to the second lead screw.

[0013] The above technical solution uses the output shaft of the third servo motor to drive the second lead screw to rotate, causing the moving block to slide on the slide rail and adjust the position of the detection component on the connecting block, which facilitates the detection of different positions of the storage tank.

[0014] Preferably, the rotating assembly includes an L-shaped block, which is fixedly connected to the outer wall of the clamping block. A movable block is slidably connected to the L-shaped block, and a C-shaped block is fixedly mounted on the movable block. A first cylinder is mounted on the movable block via a mounting seat, and one end of the piston rod of the first cylinder is fixedly connected to the outer wall of the L-shaped block.

[0015] With the above technical solution, when the piston rod of the first cylinder extends or retracts, it pushes the movable block to move on the L-shaped block, thereby adjusting the position of the C-shaped block.

[0016] Preferably, two extrusion rollers are rotatably connected inside the C-shaped block. A pulley is sleeved on the outer peripheral wall of the central shaft of the extrusion roller. The two pulleys are driven by friction through a belt. A drive motor is mounted on the top surface of the C-shaped block through a mounting base. The piston rod of the drive motor is coaxially connected to the central shaft of one of the extrusion rollers.

[0017] The above technical solution enables the two extrusion rollers to rotate synchronously. The friction between the extrusion rollers and the outer wall of the storage tank causes the two rotating components to carry the detection device around the outer wall of the storage tank, thereby enabling the detection of wall thickness at different positions around the circumference of the storage tank.

[0018] Preferably, a second cylinder is mounted on the bottom surface of the push block via a mounting base, one end of the piston rod of the second cylinder is fixedly connected to the outer wall of the moving block, and a fourth servo motor is mounted on the outer wall of the support block via a mounting base, with the output shaft of the fourth servo motor coaxially connected to the rotating shaft.

[0019] The above technical solution uses a fourth servo motor to drive the rotating shaft, which in turn rotates the rotating block on the shaft, thereby adjusting the angle of the ultrasonic thickness gauge body and the straight probe.

[0020] Preferably, a grinding motor is mounted on the rotating block via a mounting base, the output shaft of the grinding motor is rotatably connected to the rotating block, and a grinding wheel is sleeved on the output shaft of the grinding motor.

[0021] The above technical solution uses the output shaft of the grinding motor to drive the grinding wheel to rotate, thereby grinding the surface of the tank wall and improving the contact effect between the straight probe and the tank wall.

[0022] Preferably, a semicircular block is installed on the rear wall of the rotating block, and two round rods are slidably connected on the semicircular block. One end of each round rod is fixed with a tension spring, and the two tension springs are respectively located inside the semicircular block. The other ends of the two tension springs are fixedly connected to the rotating block.

[0023] The above technical solution allows the retaining ring to engage with the outer peripheral wall of the straight probe by the restoring force of the tension spring after the retaining ring is released. This facilitates the installation of the straight probe, provides favorable conditions for the calibration of the straight probe on the ultrasonic thickness gauge body, and improves the detection accuracy.

[0024] Preferably, the rear end of the semicircular block is provided with a retaining ring, which is fixedly connected to two round rods respectively. The straight probe is inserted into the semicircular block, and the outer peripheral wall of the straight probe is engaged with the inner wall of the retaining ring.

[0025] The above technical solution facilitates the rapid installation and disassembly of the straight probe, making it easier to meet different testing needs.

[0026] The beneficial effects of this utility model are:

[0027] 1. The device is clamped to the outer wall of the storage tank by clamping blocks. The rotating component can rotate on the outer wall of the storage tank, facilitating the inspection of different parts of the storage tank. During the inspection process, the position of the inspection component is adjusted by sliding the moving block connected to the slide rail. The sliding connection of the push block on the moving block pushes the support block, rotating shaft and rotating block to move synchronously, so that the straight probe of the ultrasonic thickness gauge body abuts against the outer wall of the storage tank. The ultrasonic thickness gauge body emits and receives ultrasonic signals to measure the wall thickness of the storage tank. This avoids the shaking and errors caused by hand operation, improves the inspection accuracy. The rotating component and the inspection component adapt to the wall thickness inspection needs of storage tanks at different heights and angles, improving the inspection efficiency.

[0028] 2. The output shaft of the first servo motor drives the rubber roller to rotate, and the friction between the rubber roller and the outer wall of the storage tank enables the entire detection device to move up and down on the outer wall of the storage tank, thereby adjusting the detection height. The second servo motor drives the first lead screw to rotate, causing the slider to slide in the slide groove, thereby adjusting the distance between the two clamping blocks to accommodate storage tanks of different diameters. The output shaft of the third servo motor drives the second lead screw to rotate, causing the moving block to slide on the slide rail, adjusting the position of the detection component on the connecting block, facilitating the detection of different positions on the storage tank.

[0029] 3. When the piston rod of the first cylinder extends or retracts, it pushes the movable block to move on the L-shaped block, thereby adjusting the position of the C-shaped block. This causes the outer peripheral walls of the two extrusion rollers on both sides of the storage tank to abut against the outer wall of the storage tank. At this time, the outer peripheral wall of the rubber roller separates from the outer wall of the storage tank. The drive motor drives one of the extrusion rollers to rotate, causing one pulley to be driven by belt friction to the other pulley to rotate synchronously. This causes the two extrusion rollers to rotate synchronously. The friction between the extrusion rollers and the outer wall of the storage tank causes the two rotating components to rotate around the outer wall of the storage tank with the detection device, thereby realizing the wall thickness detection at different positions around the circumference of the storage tank and improving the accuracy and stability of the detection.

[0030] 4. The piston rod of the second cylinder causes the push block to slide along the moving block, moving the support block to a suitable position. The fourth servo motor drives the rotating shaft to rotate, causing the rotating block on the shaft to rotate, adjusting the angle of the ultrasonic thickness gauge body and the straight probe. Before testing, if there are rust, dirt, or other impurities on the tank wall surface, the output shaft of the grinding motor drives the grinding wheel to rotate, grinding the tank wall surface, improving the contact effect between the straight probe and the tank wall. After grinding, the rotating block rotates to rotate the straight probe to the area ground by the grinding wheel to test the tank wall thickness, improving the testing efficiency.

[0031] 5. When installing the straight probe, pull the retaining ring to slide the two round rods along the semicircular block. At this time, the tension spring is stretched. After inserting the straight probe into the semicircular block, release the retaining ring. The restoring force of the tension spring will cause the retaining ring to engage with the outer peripheral wall of the straight probe, which facilitates the installation of the straight probe and provides favorable conditions for the calibration of the straight probe on the ultrasonic thickness gauge body, thus improving the detection accuracy. When disassembling, pull the retaining ring outward to separate it from the straight probe, and the straight probe can be removed. This facilitates the quick installation and disassembly of the straight probe, making it easy to meet different detection needs and improving the convenience and efficiency of the detection work.

[0043] The detection component 7 includes a movable block 701. The lower end of the movable block 701 is slidably connected to the outer wall of the slide rail 6 and the top surface of the connecting block 1. A push block 702 is slidably connected to the upper end of the movable block 701. A support block 703 is fixedly provided on the top surface of the push block 702. A rotating shaft 704 is rotatably connected to the upper end of the support block 703. A rotating block 705 is fixedly provided on the rotating shaft 704. An ultrasonic thickness gauge body 706 is installed on one side of the outer wall of the rotating block 705. A straight probe 707 is electrically connected to the ultrasonic thickness gauge body 706. The straight probe 707 is installed on the rear wall of one end of the rotating block 705.

[0044] A rubber roller 8 is rotatably connected inside the clamping block 2. A first servo motor 9 is mounted on the rear wall of the clamping block 2 via a mounting base. The output shaft of the first servo motor 9 is coaxially connected to the rubber roller 8. The rubber roller 8 is rotated by the output shaft of the first servo motor 9. The friction between the rubber roller 8 and the outer wall of the storage tank is used to move the entire detection device up and down on the outer wall of the storage tank, thereby adjusting the detection height.

[0045] The connecting block 1 is rotatably connected to the first lead screw 10, and the connecting block 1 is equipped with a second servo motor 11 on its side wall. The output shaft of the second servo motor 11 is coaxially connected to the first lead screw 10. The middle part of the slider 4 is threadedly connected to the first lead screw 10 through a threaded hole. The second servo motor 11 drives the first lead screw 10 to rotate, so that the slider 4 slides in the slide groove 5, thereby adjusting the distance between the two clamping blocks 2 to accommodate storage tanks of different diameters.

[0046] The upper end of the connecting block 1 is provided with a second lead screw 12. The moving block 701 is threadedly connected to the second lead screw 12 through a threaded hole. A third servo motor 13 is mounted on the connecting block 1 through a mounting base. The output shaft of the third servo motor 13 is coaxially connected to the second lead screw 12. The output shaft of the third servo motor 13 drives the second lead screw 12 to rotate, so that the moving block 701 slides on the slide rail 6, adjusting the position of the detection component 7 on the connecting block 1, so as to facilitate the detection of different positions of the storage tank.

[0047] The rotating assembly 3 includes an L-shaped block 301, which is fixedly connected to the outer wall of the clamping block 2. A movable block 302 is slidably connected to the L-shaped block 301. A C-shaped block 303 is fixedly mounted on the movable block 302. A first cylinder 308 is mounted on the movable block 302 via a mounting seat. One end of the piston rod of the first cylinder 308 is fixedly connected to the outer wall of the L-shaped block 301. When the piston rod of the first cylinder 308 extends or retracts, it pushes the movable block 302 to move on the L-shaped block 301, thereby adjusting the position of the C-shaped block 303.

[0048] Two extrusion rollers 304 are rotatably connected inside the C-shaped block 303. A pulley 305 is sleeved on the outer peripheral wall of the central shaft of the extrusion roller 304. The two pulleys 305 are driven by friction through a belt 306. A drive motor 307 is mounted on the top surface of the C-shaped block 303 through a mounting base. The piston rod of the drive motor 307 is coaxially connected to the central shaft of one of the extrusion rollers 304, so that the two extrusion rollers 304 rotate synchronously. The friction between the extrusion rollers 304 and the outer wall of the storage tank causes the two rotating components 3 to rotate around the outer wall of the storage tank with the detection device, so as to realize the wall thickness detection at different positions in the circumference of the storage tank.

[0049] Working principle: First, the device is clamped to the outer wall of the storage tank by clamping block 2. The rotating component 3 can rotate on the outer wall of the storage tank, which is convenient for detecting different parts of the storage tank. During the detection process, the position of the detection component 7 is adjusted by sliding block 701 connected to slide rail 6. Push block 702 is slidably connected to sliding block 701, which pushes support block 703, rotating shaft 704 and rotating block 705 to move synchronously, so that the straight probe 707 of ultrasonic thickness gauge body 706 abuts against the outer wall of the storage tank. The ultrasonic thickness gauge body 706 transmits and receives ultrasonic signals to measure the wall thickness of the storage tank. This avoids the shaking and errors caused by hand operation and improves the detection accuracy. The rotating component 3 and detection component 7 adapt to the wall thickness detection needs of storage tanks at different heights and angles, which improves the detection efficiency.

[0050] The output shaft of the first servo motor 9 drives the rubber roller 8 to rotate. By utilizing the friction between the rubber roller 8 and the outer wall of the storage tank, the entire detection device can move up and down on the outer wall of the storage tank, thereby adjusting the detection height. The second servo motor 11 drives the first lead screw 10 to rotate, causing the slider 4 to slide in the slide groove 5, thereby adjusting the distance between the two clamping blocks 2 to adapt to storage tanks of different diameters.

[0051] The output shaft of the third servo motor 13 drives the second lead screw 12 to rotate, so that the moving block 701 slides on the slide rail 6, adjusting the position of the detection component 7 on the connecting block 1, so as to facilitate the detection of different positions of the storage tank;

[0052] When the piston rod of the first cylinder 308 extends or retracts, it pushes the movable block 302 to move on the L-shaped block 301, thereby adjusting the position of the C-shaped block 303. This causes the outer peripheral walls of the two extrusion rollers 304 on both sides of the storage tank to abut against the outer wall of the storage tank. At this time, the outer peripheral wall of the rubber roller 8 separates from the outer wall of the storage tank. The drive motor 307 drives one of the extrusion rollers 304 to rotate, causing one of the pulleys 305 to rotate synchronously through the friction transmission of the belt 306 to the other pulley 305. This causes the two extrusion rollers 304 to rotate synchronously. The friction between the extrusion rollers 304 and the outer wall of the storage tank causes the two rotating components 3 to rotate around the outer wall of the storage tank with the detection device, thereby realizing the wall thickness detection at different positions in the circumference of the storage tank and improving the accuracy and stability of the detection.

[0053] Example 2

[0054] like Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 7 As shown, based on Embodiment 1, a second cylinder 708 is mounted on the bottom surface of the push block 702 via a mounting base. One end of the piston rod of the second cylinder 708 is fixedly connected to the outer wall of the moving block 701. A fourth servo motor 709 is mounted on the outer wall of the support block 703 via a mounting base. The output shaft of the fourth servo motor 709 is coaxially connected to the rotating shaft 704. The fourth servo motor 709 drives the rotating shaft 704 to rotate, causing the rotating block 705 on the rotating shaft 704 to rotate, thereby adjusting the angle of the ultrasonic thickness gauge body 706 and the straight probe 707.

[0055] A grinding motor 710 is mounted on the rotating block 705 via a mounting base. The output shaft of the grinding motor 710 is rotatably connected to the rotating block 705, and a grinding wheel 711 is sleeved on the output shaft of the grinding motor 710. The grinding wheel 711 is driven to rotate by the output shaft of the grinding motor 710 to grind the surface of the tank wall, thereby improving the contact effect between the straight probe 707 and the tank wall.

[0056] A semicircular block 712 is installed on the rear wall of the rotating block 705. Two round rods 713 are slidably connected to the semicircular block 712. One end of the round rod 713 is fixed with a tension spring 714. The two tension springs 714 are located inside the semicircular block 712, and the other ends of the two tension springs 714 are fixedly connected to the rotating block 705. When the retaining ring 715 is released, the restoring force of the tension spring 714 causes the retaining ring 715 to engage with the outer peripheral wall of the straight probe 707, which facilitates the installation of the straight probe 707 and provides favorable conditions for the calibration of the straight probe 707 on the ultrasonic thickness gauge body 706, thereby improving the detection accuracy.

[0057] The rear end of the semicircular block 712 is provided with a retaining ring 715, which is fixedly connected to two round rods 713 respectively. The straight probe 707 is inserted into the semicircular block 712, and the outer peripheral wall of the straight probe 707 is engaged with the inner wall of the retaining ring 715. This facilitates the quick installation and disassembly of the straight probe 707 and makes it easy to meet different testing needs.

[0058] In use, the piston rod of the second cylinder 708 causes the push block 702 to slide along the moving block 701, moving the support block 703 to a suitable position. The fourth servo motor 709 drives the rotating shaft 704 to rotate, causing the rotating block 705 on the rotating shaft 704 to rotate, adjusting the angle of the ultrasonic thickness gauge body 706 and the straight probe 707.

[0059] Before testing, if there are rust, dirt or other impurities on the surface of the tank wall, the grinding wheel 711 is driven to rotate by the output shaft of the grinding motor 710 to grind the surface of the tank wall, which improves the contact effect between the straight probe 707 and the tank wall. After grinding, the straight probe 707 is rotated to the area after grinding by the grinding wheel 711 by the rotating block 705 to test the thickness of the tank wall, which improves the testing efficiency.

[0060] When installing the straight probe 707, pulling the retaining ring 715 causes the two round rods 713 to slide along the semicircular block 712. At this time, the tension spring 714 is stretched. After inserting the straight probe 707 into the semicircular block 712, releasing the retaining ring 715 allows the retaining ring 715 to engage with the outer peripheral wall of the straight probe 707 through the restoring force of the tension spring 714. This facilitates the installation of the straight probe 707 and provides favorable conditions for the calibration of the straight probe 707 on the ultrasonic thickness gauge body 706, improving the detection accuracy. When disassembling, pulling the retaining ring 715 outward separates it from the straight probe 707, allowing the straight probe 707 to be removed. This facilitates the quick installation and disassembly of the straight probe 707, making it easier to meet different detection needs and improving the convenience and efficiency of the detection work.
