Description

Technical Field

[0001] This invention relates to the field of nondestructive testing technology, specifically to a device and method for detecting and predicting the aging state of tubular metals. Background Technology

[0002] Non-destructive testing (NDT) is the inspection, evaluation, and measurement of the integrity, uniformity, and presence of defects of the internal and surface of an object without damaging or affecting its normal function and service life. It is widely used in all stages of product manufacturing, installation, and operation and maintenance.

[0003] In the prior art, during the use of tubular metal, due to the long-term exposure to specific working conditions, the inner and outer walls of the tubular metal are in long-term contact with the surrounding medium, which causes chemical and electrochemical reactions. This results in metal atoms losing electrons and dissolving to form non-metallic compounds, thereby reducing the plasticity and toughness of the tubular metal and making it more prone to brittle fracture. If this is not detected in time and the tubular metal continues to be used, the integrity of the tubular metal will further deteriorate, leading to sudden structural failure.

[0004] Therefore, we propose a device and method for detecting and predicting the aging status of tubular metals in order to solve the problems mentioned above. Summary of the Invention

[0009] Preferably, the movable component includes a fixed cylindrical plate, the other outer surface of the second connecting plate is fixedly connected to the outer surface of the fixed cylindrical plate, rotating cylindrical plates are rotatably connected to the outer surface of the fixed cylindrical plate near both sides, two first mounting plates are fixedly connected to both sides of the outer surface of the fixed cylindrical plate, two second mounting plates are fixedly connected to both sides of the outer surface of the fixed cylindrical plate, two third mounting plates are fixedly connected to one side of the outer surface of the two rotating cylindrical plates, and two fourth mounting plates are fixedly installed on one side of the outer surface of the two rotating cylindrical plates.

[0010] Preferably, the inner walls of the four first mounting plates and the four second mounting plates are slidably connected with first positioning rods, and the inner walls of the four third mounting plates and the four fourth mounting plates are fixedly embedded with second positioning rods.

[0011] Preferably, a rotating shaft is movably embedded between the outer surfaces of the eight first positioning rods and the eight second positioning rods, and a plurality of evenly arranged rollers are fixedly sleeved on the outer surfaces of the eight rotating shafts. A rubber sleeve is fixedly sleeved on the outer surfaces of the plurality of rollers, and a connecting shaft is movably embedded in the inner walls of the two second positioning rods.

[0012] Preferably, one end of each of the two connecting shafts is fixedly connected to one end of one of the two rotating shafts, and the other end of each of the two connecting shafts is fixedly fitted with a first gear. A third connecting plate is fixedly connected between the outer surfaces of the two rotating cylinder plates, and the outer surface of the third connecting plate is slidably connected to the outer surface of the fixed cylinder plate.

[0015] The method of using the tubular metal aging condition detection and prediction device includes the following steps:

[0016] S1. During the use of tubular metal and its gradual aging, in order to detect and predict the aging state of the tubular metal, the staff needs to place the tubular metal inside multiple rollers. At this time, the hydraulic rod is activated to drive the rotating cylinder plate to rotate. The rotating cylinder plate will change the distance between multiple rollers until the distance between multiple rollers is appropriate. The tubular metal is then placed in multiple rollers and magnetic plates.

[0017] S2. At this time, the hydraulic rod is started again to drive the rotating cylinder plate to rotate and reduce the distance between the multiple rollers until the outer surface of the rubber sleeve is in contact with the tubular metal.

[0018] S3. At this time, multiple magnetic plates will attract the tubular metal. The motor will start and drive the output shaft to rotate. The output shaft will drive the second gear to rotate and the meshing first gear to rotate. The first gear will drive the roller to rotate. The roller will drive the outer surface of the rubber sleeve to rotate and move along the outer surface of the tubular metal, thereby driving the detection component to move along the outer surface of the tubular metal.

[0019] S4. During long-term use, tubular metal will generate non-magnetic and weakly magnetic oxides. The greater the aging degree of the tubular metal, the more non-magnetic and weakly magnetic oxides are generated over time, resulting in a weaker attraction of the magnetic plate to the tubular metal. The attraction between the magnetic plate and the tubular metal will cause the two first connecting plates to move towards each other. The distance sensor detects the distance between the two first connecting plates to determine the aging degree of the tubular metal at this time. By detecting the aging degree of the tubular metal at equal time intervals, the aging state of the tubular metal can be predicted.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. During use, by placing the tubular metal inside the detection component, the more non-metallic compounds are formed during the use of the tubular metal, the worse its plasticity and toughness become. At the same time, the magnetic force of the magnetic plate on the tubular metal is smaller, and the pressure of the two first connecting plates on the spring is smaller, thus the distance between the two first connecting plates is larger. The distance sensor detects the distance and transmits the data to the data analysis display to analyze and predict the aging state of the tubular metal. This solves the problem in the existing technology that the reduction in plasticity and toughness of the tubular metal is not detected in time, and the tubular metal is prone to brittle fracture. If it continues to be used, the integrity of the tubular metal will be further deteriorated, leading to sudden structural failure.

[0022] 2. In use, by setting a hydraulic rod to drive the rotating cylinder plate to rotate, the outer surface of the first positioning rod will slide along the inner wall of the first mounting plate and the second mounting plate, thereby driving multiple rollers to move and changing the distance between the multiple rollers. This change in the distance between the multiple rollers can clamp tubular metals of different diameters, improving the versatility of the tubular metal aging state detection and prediction device.

[0023] 3. In use, the motor drives the second gear to rotate, which in turn drives the first gear to rotate. The first gear then drives some of the rollers to rotate, which in turn drives the rubber sleeve to rotate and move along the outer surface of the tubular metal. This, in turn, moves the detection component along the path of the tubular metal, enabling comprehensive detection and prediction of the tubular metal. This ensures the reliability of the detection and prediction results of the aging state of the tubular metal. Attached Figure Description

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Reference Figure 1-8The device for detecting and predicting the aging state of tubular metal includes a detection component 1. A moving component 2 is provided on one outer surface of the detection component 1 to move the detection component 1 outside the tubular metal. The detection component 1 includes an arc plate 111 and multiple first connecting plates 101. The multiple first connecting plates 101 are grouped in pairs. A fixing rod 103 is slidably connected between the inner walls of each group of first connecting plates 101. A spring 102 is provided between the outer surfaces of each group of first connecting plates 101. First fixing shafts 104 are fixedly embedded near the two edges of the inner walls of the multiple first fixing shafts 101. First rotating plates 105 are movably sleeved on the outer surfaces of the multiple first fixing shafts 104. Second fixing shafts 107 are movably embedded near one edge of the inner walls of the multiple first rotating plates 105. Each adjacent second fixing shaft 107... Two are grouped together. In some groups, a first fixing plate 106 is fixedly sleeved between the outer surfaces of the second fixing shafts 107. In the remaining groups, a second fixing plate 108 is fixedly sleeved between the outer surfaces of the second fixing shafts 107. A magnetic plate 110 is provided on the outer surface of multiple first fixing plates 106. The two ends of multiple springs 102 are fixedly connected to the outer surfaces of multiple first connecting plates 101 respectively. A third fixing shaft 109 is fixedly embedded in the inner wall of multiple second fixing plates 108. The outer surfaces of multiple third fixing shafts 109 are fixedly embedded in the inner wall of the arc plate 111 near both ends. A distance sensor 112 is provided on the outer surface of some first connecting plates 101. A second connecting plate 113 is fixedly connected to the outer surface of the arc plate 111. A data analysis display 114 is provided on one side of the outer surface of the second connecting plate 113.

[0036] In this embodiment, during the detection of the aging state of the tubular metal, the operator first needs to activate the hydraulic rod 221 to drive the rubber sleeves 211 on multiple rollers 210 to clamp the tubular metal. At this time, the tubular metal is located inside multiple magnetic plates 110. During use, the ferromagnetic material in the tubular metal will oxidize and corrode when exposed to air and moisture for a long time, thus generating a layer of non-magnetic and weakly magnetic oxides. The greater the degree of aging of the tubular metal, the more non-magnetic and weakly magnetic oxides are generated over time, and thus the weaker the attraction of the magnetic plates 110 to the tubular metal. The less the degree of aging of the tubular metal, the less non-magnetic and weakly magnetic oxides are generated, and thus the weaker the attraction of the magnetic plates 110 to the tubular metal. The greater the attraction of the metal, the stronger the attraction between the magnetic plate 110 and the tubular metal, causing the magnetic plate 110 to move towards the outer surface of the tubular metal. The magnetic plate 110 then moves the first fixed plate 106, which in turn moves the two second fixed shafts 107 fixedly embedded in the inner wall. These two second fixed shafts 107 move two of the first rotating plates 105. One end of each first rotating plate 105 rotates along the outer surface of the second fixed shaft 107, while the other end rotates along the outer surface of the first fixed shaft 104, simultaneously moving the two first connecting plates 101. The inner walls of the two first connecting plates 101 slide along the outer surface of the fixing rod 103, moving towards each other and thus impacting the spring 102. When the tubular metal is compressed, the two first connecting plates 101 move, which in turn drives the two other first fixed shafts 104 to move. These two first fixed shafts 104 then drive the two other first rotating plates 105 to move. The inner wall of one side of each of the two first rotating plates 105 rotates along the inner wall of the first fixed shaft 104, and the inner wall of the other side rotates along the outer surface of the second fixed shaft 107 located on the second fixed plate 108. When the magnetic force between the tubular metal and the magnetic plate 110 is greater, the magnetic plate 110 moves closer to the tubular metal. At this time, the pressure of the two first connecting plates 101 on the spring 102 is greater, and the distance between the two first connecting plates 101 is smaller. When the magnetic force between the tubular metal and the magnetic plate 110 is greater... The smaller the force, the less the magnetic plate 110 will move closer to the tubular metal. At this time, the pressure of the two first connecting plates 101 on the spring 102 is smaller, and the distance between the two first connecting plates 101 is larger. The distance between the two first connecting plates 101 is detected by the distance sensor 112 to determine the degree of aging of the tubular metal. The degree of aging is displayed on the data analysis display 114. By detecting the degree of aging of the tubular metal at equal time intervals, the aging state of the tubular metal can be predicted. This device, by setting up a detection component 1, places the tubular metal inside the detection component 1. The more non-metallic compounds formed by the tubular metal during use, the worse its plasticity and toughness.Simultaneously, the weaker the magnetic force of the magnetic plate 110 on the tubular metal, the smaller the pressure of the two first connecting plates 101 on the spring 102, thus increasing the distance between the two first connecting plates 101. Distance sensor 112 detects the distance and transmits the data to the data analysis display 114 to analyze and predict the aging state of the tubular metal. This solves the problem in existing technologies where, if the reduced plasticity and toughness of the tubular metal are not detected in time, leading to brittle fracture and continued use, the integrity of the tubular metal will further deteriorate, resulting in sudden structural failure.

[0037] like Figure 1-8 As shown, the movable component 2 includes a fixed cylindrical plate 201. The outer surface of the second connecting plate 113 on the other side is fixedly connected to the outer surface of the fixed cylindrical plate 201. Rotating cylindrical plates 202 are rotatably connected to the outer surface of the fixed cylindrical plate 201 near both sides. Two first mounting plates 203 are fixedly connected to both sides of the outer surface of the fixed cylindrical plate 201. Two second mounting plates 204 are fixedly connected to both sides of the outer surface of the fixed cylindrical plate 201. Two third mounting plates 205 are fixedly connected to one side of the outer surface of each of the two rotating cylindrical plates 202. Two fourth mounting plates 205 are fixedly installed on one side of the outer surface of each of the two rotating cylindrical plates 202. 06. The inner walls of the four first mounting plates 203 and the four second mounting plates 204 are slidably connected with first positioning rods 207. The inner walls of the four third mounting plates 205 and the four fourth mounting plates 206 are fixedly embedded with second positioning rods 208. Rotating shafts 209 are movably embedded between the outer surfaces of the eight first positioning rods 207 and the eight second positioning rods 208. Multiple evenly arranged rollers 210 are fixedly sleeved on the outer surfaces of the eight rotating shafts 209. Rubber sleeves 211 are fixedly sleeved on the outer surfaces of the multiple rollers 210. Connecting shafts 212 are movably embedded in the inner walls of the two second positioning rods 208.

[0038] In this embodiment, before inspecting the tubular metal, the operator needs to activate the hydraulic rod 221 to move the fourth fixed shaft 219. As the fourth fixed shaft 219 moves, it rotates along the inner wall of the hydraulic rod 221. Simultaneously, the fourth fixed shaft 219 causes the outer surface of the rotating cylinder plate 202 to rotate along the inner wall of the fixed cylinder plate 201. The rotating cylinder plate 202 then causes multiple third mounting plates 205 and multiple fourth mounting plates 206 to rotate, and simultaneously causes the third connecting plate 214 to rotate and move. The third mounting plates 205 and fourth mounting plates 206 then cause the second positioning rods 208 to rotate and move. While the two second positioning rods 208 rotate and move, they also cause the connecting shaft 212 to rotate and move. The connecting shaft 212 drives the first gear 213 to rotate, while the third connecting plate 214 drives the motor 215 to move. The motor 215 drives the output shaft 216 to rotate, which in turn drives the second gear 217 to rotate. The first gear 213 and the second gear 217 rotate synchronously, ensuring that the first gear 213 is always meshed with the outer surface of the second gear 217. The outer surface of the second positioning rod 208 is fixed to the inner walls of the third mounting plate 205 and the fourth mounting plate 206, thus the second positioning rod 208 drives the rotating shaft 209 to move. The rotating shaft 209 then drives the external roller 210 to move, which in turn drives the external rubber sleeve. As the rotating shaft 209 moves, it drives the first positioning rod 207 at the other end to move as well. Since the first positioning rod 207 is externally slidably connected to the first mounting plate 203 and the second mounting plate 204, and the first mounting plate 203 and the second mounting plate 204 are fixedly mounted on the fixed cylindrical plate 201, the outer surface of the first positioning rod 207 slides along the inner walls of the first mounting plate 203 and the second mounting plate 204. This changes the distance between the multiple rollers 210 until the distance between the multiple rollers 210 is sufficient to accommodate a suitable external tubular metal. The operator then places the external tubular metal onto the multiple rollers 210 and the magnetic plate. In step 110, the hydraulic rod 221 is activated again to rotate the rotating cylinder plate 202, thereby reducing the distance between the multiple rollers 210 until the outer surface of the rubber sleeve 211 is in contact with the tubular metal. This device, by setting the hydraulic rod 221 to rotate the rotating cylinder plate 202, causes the outer surface of the first positioning rod 207 to slide along the inner wall of the first mounting plate 203 and the second mounting plate 204, thereby moving the multiple rollers 210 and changing the distance between them. This change in the distance between the multiple rollers 210 enables the clamping of tubular metals of different diameters, improving the versatility of the tubular metal aging condition detection and prediction device.

[0039] like Figure 1-8As shown, one end of each of the two connecting shafts 212 is fixedly connected to one end of each of the two rotating shafts 209. The other end of each of the two connecting shafts 212 is fixedly fitted with a first gear 213. A third connecting plate 214 is fixedly connected between the outer surfaces of the two rotating cylinder plates 202. The outer surface of the third connecting plate 214 is slidably connected to the outer surface of the fixed cylinder plate 201. A motor 215 is installed on the outer surface of the third connecting plate 214. An output shaft 216 is fixedly connected to the output end of the motor 215. A second gear 217 is fixedly fitted on the outer surface of the output shaft 216. The outer surfaces of the second gear 217 mesh with the outer surfaces of the two first gears 213. A connecting block 218 is fixedly connected to the outer surfaces of the two rotating cylinder plates 202. A fourth fixed shaft 219 is fixedly embedded between the inner walls of the two connecting blocks 218. A fourth connecting plate 220 is fixedly connected to one side of the outer surface of the second connecting plate 113. A hydraulic rod 221 is installed on one side of the outer surface of the fourth connecting plate 220. One end of the hydraulic rod 221 is rotatably connected to the outer surface of the fourth fixed shaft 219.

[0040] In this embodiment, during the detection of the aging state of the tubular metal, the operator first needs to activate the hydraulic rod 221 to drive the rubber sleeves 211 on multiple rollers 210 to clamp the tubular metal. At this time, the tubular metal is located inside the detection component 1. Then, the motor 215 is activated, which drives the output shaft 216 to rotate. The output shaft 216 drives the second gear 217 to rotate, which in turn drives the meshing first gear 213 to rotate. The rotation of the first gear 213 drives the connecting shaft 212 to rotate, which in turn drives the connected rotating shaft 209 to rotate. The rotating shaft 209 drives the rollers 210 to rotate, and the rollers 210 move the outer surface of the rubber sleeves 211 along the tubular metal. The outer surface of the tubular metal rotates and moves, and the rubber sleeve 211 increases the friction between the tubular metal and the tubular metal, thus enabling it to roll along the outer surface of the tubular metal. This drives the detection component 1 to move along the outer surface of the tubular metal. The device is equipped with a motor 215 that drives the second gear 217 to rotate, which in turn drives the first gear 213 to rotate. The first gear 213 drives some of the rollers 210 to rotate, and the rollers 210 drive the rubber sleeve 211 to rotate and move along the outer surface of the tubular metal, thereby driving the detection component 1 to move along the path of the tubular metal. This allows for comprehensive detection and prediction of the tubular metal, thus ensuring the reliability of the detection and prediction results of the aging state of the tubular metal.

[0041] In this invention, when inspecting tubular metal, the operator needs to activate the hydraulic rod 221 to move the fourth fixed shaft 219. As the fourth fixed shaft 219 moves, it rotates along the inner wall of the hydraulic rod 221. Simultaneously, the fourth fixed shaft 219 causes the outer surface of the rotating cylinder plate 202 to rotate along the inner wall of the fixed cylinder plate 201. The rotating cylinder plate 202 then causes multiple third mounting plates 205 and multiple fourth mounting plates 206 to rotate, and simultaneously causes the third connecting plate 214 to rotate and move. The third mounting plates 205 and fourth mounting plates 206 then cause the second positioning rods 208 to rotate and move. While the two second positioning rods 208 rotate and move, they also cause the connecting shaft 212 to rotate and move. The connecting shaft 212 then causes the first gear 213 to rotate. As the first gear rotates, the third connecting plate 214 drives the motor 215 to move, which in turn drives the output shaft 216 to rotate. The output shaft 216 then drives the second gear 217 to rotate. The first gear 213 and the second gear 217 rotate synchronously, ensuring that the first gear 213 is always meshed with the outer surface of the second gear 217. The outer surface of the second positioning rod 208 is fixed to the inner walls of the third mounting plate 205 and the fourth mounting plate 206, thus the second positioning rod 208 drives the rotating shaft 209 to move. The rotating shaft 209 then drives the external roller 210 to move, which in turn drives the external rubber sleeve 211 to move. Simultaneously, as the rotating shaft 209 moves, it also drives the first positioning rod 207 at the other end to move. As the first positioning rod 207 moves, it is externally slidably connected to the first mounting plate 203 and the second mounting plate 204, which are fixedly mounted on the fixed cylindrical plate 201. Since the fixed cylindrical plate 201 is fixed, the outer surface of the first positioning rod 207 slides along the inner walls of the first mounting plate 203 and the second mounting plate 204, thereby changing the distance between the multiple rollers 210. This continues until the distance between the multiple rollers 210 is sufficient to accommodate a suitable external tubular metal. The operator then places the external tubular metal between the multiple rollers 210 and the magnetic plate 110. At this point, the hydraulic rod 221 is activated again to rotate the rotating cylindrical plate 202, reducing the distance between the multiple rollers 210 until the distance between the multiple rollers 210 is reduced. When the outer surface of the rubber sleeve 211 comes into contact with the tubular metal, multiple magnetic plates 110 attract the tubular metal. Simultaneously, the motor 215 is activated, driving the output shaft 216 to rotate. The output shaft 216 drives the second gear 217 to rotate, which in turn drives the meshing first gear 213 to rotate. The rotation of the first gear 213 drives the connecting shaft 212 to rotate, which in turn drives the connected rotating shaft 209 to rotate. The rotating shaft 209 drives the roller 210 to rotate, causing the outer surface of the rubber sleeve 211 to rotate and move along the outer surface of the tubular metal. The rubber sleeve 211 rolls along the outer surface of the tubular metal, causing the detection component 1 to move along the outer surface of the tubular metal.During use, the ferromagnetic material within the tubular metal undergoes oxidation and corrosion when exposed to air and moisture for extended periods. This results in the formation of a layer of non-magnetic and weakly magnetic oxides. The greater the aging of the tubular metal, the more non-magnetic and weakly magnetic oxides are formed over time, thus weakening the attraction of the magnetic plate 110 to the tubular metal. Conversely, less aging of the tubular metal results in fewer non-magnetic and weakly magnetic oxides, leading to a stronger attraction between the magnetic plate 110 and the tubular metal. This attraction causes the magnetic plate 110 to move towards the outer surface of the tubular metal. The magnetic plate 110 drives the first fixed plate 106 to move, which in turn drives the two second fixed shafts 107 fixedly embedded in the inner wall to move. The two second fixed shafts 107 drive the two first rotating plates 105 to move. One end of each first rotating plate 105 rotates along the outer surface of the second fixed shaft 107, while the other end rotates along the outer surface of the first fixed shaft 104, simultaneously driving the two first connecting plates 101 to move. The inner walls of the two first connecting plates 101 slide along the outer surface of the fixed rod 103, moving towards each other and thus compressing the spring 102. When the connecting plate 101 moves, it drives the other two first fixed shafts 104 to move. The other two first fixed shafts 104 drive the other two first rotating plates 105 to move. The inner wall of one side of the other two first rotating plates 105 rotates along the inner wall of the first fixed shaft 104, and the inner wall of the other side of the other two first rotating plates 105 rotates along the outer surface of the second fixed shaft 107 located on the second fixed plate 108. When the magnetic force between the tubular metal and the magnetic plate 110 is greater, the magnetic plate 110 will move closer to the tubular metal. At this time, the pressure of the two first connecting plates 101 on the spring 102 is greater. The smaller the distance between the connecting plates 101, the weaker the magnetic force between the tubular metal and the magnetic plate 110, and the less the magnetic plate 110 will move towards the tubular metal. At this time, the pressure of the two connecting plates 101 on the spring 102 is smaller, and the greater the distance between the two connecting plates 101. The distance between the two connecting plates 101 is detected by the distance sensor 112 to determine the degree of aging of the tubular metal. The degree of aging is displayed on the data analysis display 114. By detecting the degree of aging of the tubular metal at equal time intervals, the aging state of the tubular metal can be predicted.

9. A device and method for detecting and predicting the aging state of tubular metals, characterized in that, The tubular metal aging state detection and prediction device according to claim 8 includes the following steps: S1. During the use of the tubular metal and its gradual aging, in order to detect and predict the aging state of the tubular metal, the operator needs to place the tubular metal inside multiple rollers (210). At this time, the hydraulic rod (221) is activated to drive the rotating cylinder plate (202) to rotate. The rotating cylinder plate (202) will change the distance between multiple rollers (210) until the distance between multiple rollers (210) is appropriate. The tubular metal is then placed in multiple rollers (210) and magnetic plate (110). S2. At this time, the hydraulic rod (221) is activated again to drive the rotating cylinder plate (202) to rotate and reduce the distance between the multiple rollers (210) until the multiple rollers (210) drive the outer surface of the rubber sleeve (211) to fit against the tubular metal. S3. At this time, multiple magnetic plates (110) will attract the tubular metal. The motor (215) will start and drive the output shaft (216) to rotate. The output shaft (216) will drive the second gear (217) to rotate and the meshing first gear (213) to rotate. The first gear (213) will drive the roller (210) to rotate. The roller (210) will drive the outer surface of the rubber sleeve (211) to rotate and move along the outer surface of the tubular metal, thereby driving the detection component (1) to move along the outer surface of the tubular metal. S4. During long-term use, tubular metal will generate non-magnetic and weakly magnetic oxides. The greater the aging degree of the tubular metal, the more non-magnetic and weakly magnetic oxides are generated over time, resulting in a smaller attraction force of the magnetic plate (110) on the tubular metal. The attraction force between the magnetic plate (110) and the tubular metal will drive the two first connecting plates (101) to move towards each other. The distance sensor (112) is used to detect the distance between the two first connecting plates (101) to determine the aging degree of the tubular metal at this time. By detecting the aging degree of the tubular metal at the same time interval, the aging state of the tubular metal can be predicted.
