Description

Technical Field

[0001] This invention relates to the field of materials technology, specifically a quality inspection device for the production of galvanized steel pipes, which involves measuring the physical properties of materials to test or analyze them. Background Technology

[0002] Galvanized steel pipe is a type of metal pipe with a zinc layer coated on the surface of ordinary carbon steel pipe (or low alloy steel pipe) through a galvanizing process. Its core function is to protect the steel pipe substrate by utilizing the chemical properties of zinc, which greatly improves its corrosion resistance, while retaining the high strength and easy processing advantages of the steel pipe itself. It is widely used in fluid transportation, structural support and other scenarios.

[0003] Existing quality inspection devices for galvanized steel pipe production have the following shortcomings: Traditional inspection devices mostly adopt a single external inspection or segmented internal inspection mode. External inspection is easily affected by environmental factors such as stains on the steel pipe surface and light, leading to misjudgments of defects such as uneven zinc layer thickness and surface scratches. Internal inspection often requires manual assistance to push the inspection components, making it difficult to achieve full-length and uniform inspection. Moreover, the inspection data needs to be manually summarized and analyzed, which is inefficient. In addition, the steel pipe positioning stability is poor during the inspection process, and the inspection point is easily shifted due to shaking, which further affects the inspection accuracy. Therefore, it cannot meet the needs of rapid and accurate quality inspection of galvanized steel pipes in large-scale production.

[0004] Therefore, we propose a quality inspection device for the production of galvanized steel pipes to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to provide a quality inspection device for the production of galvanized steel pipes. It addresses the problems of low detection accuracy, poor efficiency, and insufficient stability of traditional galvanized steel pipe inspection devices by using multiple mechanisms in synergy to achieve simultaneous and accurate detection of the internal and external quality of galvanized steel pipes, while improving the degree of automation and data processing efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a quality inspection device for the production of galvanized steel pipes, comprising an overall support frame, a transport pipeline mechanism, an internal rotation detection mechanism, a propulsion transmission mechanism, an external inspection mechanism moving part, and an external inspection mechanism. The transport pipeline mechanism is installed at the bottom of the overall support frame. The internal rotation detection mechanism is connected to the propulsion transmission mechanism and can extend into the body of the galvanized steel pipe. The external inspection mechanism moving part is fixed to the top of the overall support frame. The external inspection mechanism is connected to the external inspection mechanism moving part and surrounds the outside of the body of the galvanized steel pipe. The internal rotation detection mechanism of the pipeline includes a transmission rod, a transmission sleeve sleeved on the outer side of the transmission rod, a connecting seat fixed to one end of the transmission sleeve, and transmission support fixing rods symmetrically installed on both sides of the connecting seat. The outer wall of the transmission support fixing rod is wrapped with a flexible protective ring, which reduces frictional damage between the transmission support fixing rod and the inner wall of the galvanized steel pipe, and enhances the stability of the detection mechanism inside the steel pipe. One end of the transmission support fixing rod is connected to a rotating mounting seat, and a set of annular mounting seats is provided on each side of the rotating mounting seat. An annular connecting limit plate is installed on the inner side of each set of annular mounting seats. The plate is rotatably embedded in the groove and is connected to an annular connecting limiting plate. A two-sided annular limiting plate separator is provided between the two sets of annular connecting limiting plates to prevent mutual interference between the two sets of annular connecting limiting plates during rotation. A sensor mounting ring is fixed to the inner side of the annular connecting limiting plate. A first detection sensor and a pipe inner wall position probe are evenly distributed on the sensor mounting ring. The first detection sensor is used to detect the zinc layer thickness, surface defects, and zinc layer adhesion on the inner wall of the galvanized steel pipe. The pipe inner wall position probe is used to provide real-time feedback on the position coordinates of the detection mechanism inside the steel pipe, avoiding detection blind spots.

[0007] Preferably, the sensor mounting ring is also connected to a data transmission pipe, the end of which extends away from the sensor mounting ring to an external data processing terminal for transmitting detection data to the terminal for analysis in real time. The end of the transmission rod away from the connecting seat is connected to a propulsion transmission mechanism, which includes a mounting fastener.

[0008] Preferably, the mounting fastener is fixedly connected to the overall support frame. A propulsion bearing seat is installed on the inner side of the mounting fastener. A drive shaft runs through the inside of the propulsion bearing seat. One end of the drive shaft is connected to a drive rod. Propulsion helical blades are surrounded on the outer side of the drive shaft. The propulsion helical blades are used to push the internal rotation detection mechanism of the pipe to smoothly extend into or withdraw from the galvanized steel pipe body when the drive shaft rotates. A clamping component is symmetrically provided at the end of the drive shaft away from the drive rod. The clamping component is used to fix the position of the drive shaft and assist in transmission to prevent the drive shaft from deviating during operation.

[0009] Preferably, a transport pipe mechanism is installed at the bottom of the overall support frame. The transport pipe mechanism includes a transport guide rail, which is fixed to the bottom of the overall support frame. A transport slider is slidably connected to the transport guide rail. The transport slider is electrically connected to a drive motor, which drives the transport slider to move along the transport guide rail.

[0010] Preferably, a lifting support column is vertically installed on the top of the transport slider, and a pipe lifting arc frame is fixed at the top of the lifting support column. The arc surface of the pipe lifting arc frame is adapted to the outer wall of the galvanized steel pipe body to lift and fix the galvanized steel pipe body. At the same time, the height of the lifting support column can be adjusted to accommodate galvanized steel pipes of different diameters.

[0011] Preferably, an external detection mechanism moving part is fixed to the top of the overall support frame. The external detection mechanism moving part includes a mounting top plate, which is fixed to the top of the overall support frame. A moving groove is opened on the bottom surface of the mounting top plate, and a control moving seat is slidably connected in the moving groove.

[0012] Preferably, the control moving seat is electrically connected to the synchronous moving control component, which is used to control the moving trajectory of the control moving seat to ensure that its moving speed is synchronized with the transport speed of the transport pipeline mechanism; a moving action connecting component is fixed on the control moving seat, and an external pipeline detection mechanism is connected to the end of the moving action connecting component away from the control moving seat.

[0013] Preferably, the external pipeline inspection mechanism includes an annular frame, which is connected to a control moving seat via a movable connecting member. Adjustable telescopic blocks are evenly distributed on the inner side of the annular frame, and a second detection sensor is installed at the end of each adjustable telescopic block.

[0014] Preferably, the adjustable telescopic block can adjust its length according to the outer diameter of the galvanized steel pipe body, so that the second detection sensor always maintains the optimal detection distance with the outer wall of the steel pipe; the second detection sensor is connected to a first information transmission line, and the end of the first information transmission line away from the second detection sensor passes into the inside of the line sleeve and is connected to the second information transmission line inside the line sleeve.

[0015] Preferably, the line sleeve is used to protect the information transmission line and prevent the line from being damaged; the end of the second information transmission line away from the first information transmission line is connected to the information processing integration chamber, and the information processing integration chamber is connected to the external data processing terminal for integrating the detection data transmitted by the first detection sensor and the second detection sensor, and generating a detection report to be fed back to the external terminal.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention overcomes the limitations of traditional single-detection modes by constructing a collaborative system of internal and external synchronous detection and automated transmission, achieving precise and efficient quality inspection of galvanized steel pipes. At the internal detection end, the multi-component cooperation of the internal rotating detection mechanism, along with a flexible protective ring, prevents frictional damage to the inner wall of the steel pipe and enhances the stability of the mechanism within the pipe. The combination of a ring-shaped connecting limit plate and a separator ensures flexible and interference-free rotation of the detection components. The first detection sensor, in conjunction with the pipe inner wall position probe, comprehensively covers the detection of zinc layer thickness, surface defects, and adhesion, accurately locating the detection area and eliminating blind spots. At the external detection end, the external detection mechanism's moving component, through a synchronous movement control component, keeps the external detection mechanism synchronized with the transported steel pipe at the same speed. An adjustable telescopic block adapts to steel pipes of different diameters, ensuring the second detection sensor is always at the optimal detection distance. Internal and external detection data are integrated into the information processing chamber and fed back in real time, significantly reducing environmental interference and human error, and significantly improving detection accuracy.

[0017] 2. This invention integrates modular design with automation technology, achieving both adaptability and high efficiency to meet the needs of large-scale production. In the transport pipeline mechanism, the combination of the lifting support column and the pipeline lifting arc frame allows for height adjustment according to the steel pipe diameter, achieving stable positioning and preventing point displacement caused by steel pipe swaying during inspection. The propulsion transmission mechanism relies on propulsion spiral blades and clamping components to achieve smooth insertion and extraction of the internal inspection mechanism, eliminating the need for manual assistance and reducing labor costs. In the data transmission stage, the data transmission pipeline and information transmission line work together to transmit inspection data to the terminal in real time, eliminating the need for manual summarization and analysis, and significantly improving inspection efficiency. Simultaneously, each mechanism operates independently yet collaboratively, allowing for flexible adjustments according to inspection needs to adapt to the inspection of galvanized steel pipes of different specifications, reducing equipment limitations and providing efficient and reliable technical support for quality control in galvanized steel pipe production.

[0020] 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.

[0021] This invention addresses the problems of low detection accuracy, poor efficiency, and insufficient stability of traditional galvanized steel pipe testing devices, which cannot meet the needs of rapid and accurate testing in large-scale production. Traditional testing devices often employ single external testing or segmented internal testing, which are susceptible to environmental interference, require manual assistance, have low data processing efficiency, and result in unstable steel pipe positioning and easy displacement of testing points. This invention was developed to address the problems of the prior art by setting up an internal rotation detection mechanism 100 and an external detection mechanism moving part 400. Through multi-sensor collaboration and synchronous movement control, it achieves accurate detection of the internal and external parts simultaneously. In conjunction with the propulsion transmission mechanism 200 and the transport pipeline mechanism 300, it improves the degree of automation. At the same time, it adapts to steel pipes of different specifications through an adjustable structure.

[0022] Example 1, please refer to Figure 1 and Figure 7 As shown, the present invention provides a technical solution: a quality inspection device for the production of galvanized steel pipes, comprising an overall support frame 6, a transport pipeline mechanism 300, an internal rotation inspection mechanism 100, a propulsion transmission mechanism 200, an external inspection mechanism moving part 400, and an external inspection mechanism 500. The transport pipeline mechanism 300 is installed at the bottom of the overall support frame 6. The internal rotation inspection mechanism 100 is connected to the propulsion transmission mechanism 200 and can extend into the interior of the galvanized steel pipe body 7. The external inspection mechanism moving part 400 is fixed to the top of the overall support frame 6. The external inspection mechanism 500 is connected to the external inspection mechanism moving part 400 and surrounds the outside of the galvanized steel pipe body 7.

[0023] In some embodiments, such as Figures 3-6As shown, the internal rotation detection mechanism 100 of the pipeline includes a transmission rod 102, a transmission sleeve 103 is sleeved on the outside of the transmission rod 102, a connecting seat 104 is fixed at one end of the transmission sleeve 103, and transmission support fixing rods 105 are symmetrically installed on both sides of the connecting seat 104. The outer wall of the transmission support fixing rod 105 is wrapped with a flexible protective ring 106. The flexible protective ring 106 is used to reduce the frictional damage between the transmission support fixing rod 105 and the inner wall of the galvanized steel pipe body 7, and at the same time enhance the stability of the detection mechanism inside the steel pipe. One end of the transmission support fixing rod 105 is connected to a rotating mounting seat 111. A set of annular mounting seats 107 are respectively provided on both sides of the rotating mounting seat 111. Annular connecting limiting plates 108 are installed on the inner side of each set of annular mounting seats 107. The limiting plates are rotatably connected to the annular connecting limiting plates 108 within the rotating insertion groove 112. A two-sided annular limiting plate separator 114 is provided between the two sets of annular connecting limiting plates 108 to prevent mutual interference between the two sets of annular connecting limiting plates 108 during rotation. A sensor mounting ring 110 is fixed to the inner side of the annular connecting limiting plate 108. A first detection sensor 109 and a pipe inner wall position probe 113 are evenly distributed on the sensor mounting ring 110. The first detection sensor 109 is used to detect the zinc layer thickness, surface defects, and zinc layer adhesion of the inner wall of the galvanized steel pipe body 7. The pipe inner wall position probe 113 is used to provide real-time feedback to the detection mechanism. The internal coordinates of the steel pipe are used to avoid blind spots in detection. The sensor mounting ring 110 is also connected to a data transmission pipe 101. The end of the data transmission pipe 101 away from the sensor mounting ring 110 extends to the external data processing terminal for transmitting detection data to the terminal for analysis in real time. The end of the transmission rod 102 away from the connecting seat 104 is connected to a propulsion transmission mechanism 200. The propulsion transmission mechanism 200 includes a mounting fastener 201, which is fixedly connected to the overall support frame 6. A propulsion bearing seat 203 is installed on the inner side of the mounting fastener 201. A transmission shaft 204 runs through the inside of the propulsion bearing seat 203. One end of the transmission shaft 204 is connected to the transmission rod 102. A propulsion spiral blade 202 surrounds the outer side of the transmission shaft 204. The propulsion spiral blade 202 is used to push the internal rotation detection mechanism 100 to smoothly extend into or withdraw from the galvanized steel pipe body 7 when the transmission shaft 204 rotates.A clamping component 205 is symmetrically provided at the end of the drive shaft 204 away from the drive rod 102. The clamping component 205 is used to fix the position of the drive shaft 204 and assist the transmission, preventing the drive shaft 204 from shifting during operation. A transport pipe mechanism 300 is installed at the bottom of the overall support frame 6. The transport pipe mechanism 300 includes a transport guide rail 302, which is fixed to the bottom of the overall support frame 6. A transport slider 303 is slidably connected to the transport guide rail 302. The transport slider 303 is electrically connected to the drive motor 301. The drive motor 301 is used to drive the transport slider 303 to move along the transport guide rail 302. A lifting support column 304 is vertically installed on the top of the transport slider 303. A pipe lifting arc frame 305 is fixed at the top of the lifting support column 304. The arc surface of the pipe lifting arc frame 305 is adapted to the outer wall of the galvanized steel pipe body 7, and is used to lift and fix the galvanized steel pipe body 7. At the same time, the height of the lifting support column 304 can be adjusted to accommodate galvanized steel pipes of different diameters.

[0024] When using, such as Figure 1 and Figures 3-8 As shown, the device has a frame structure. Before use, the height of the lifting support column 304 in the transport pipeline mechanism 300 needs to be adjusted according to the diameter of the galvanized steel pipe body 7 to be tested, so that the arc surface of the pipeline lifting arc frame 305 is in close contact with the outer wall of the steel pipe, ensuring the stability of the steel pipe. Then, the galvanized steel pipe body 7 is placed on the pipeline lifting arc frame 305, the drive motor 301 is turned on, and the transport slider 303 is driven to move along the transport guide rail 302 to transport the steel pipe to the testing station, that is, between the internal rotating testing mechanism 100 and the external testing mechanism 500. Then, the propulsion transmission mechanism 200 is started. The transmission shaft 204 rotates under the support of the propulsion bearing seat 203, and the outer surrounding propulsion spiral blades 202 rotate synchronously, generating a smooth propulsion force, which pushes the transmission rod 102 to drive the internal rotating testing mechanism 100 to slowly extend into the galvanized steel pipe body 7. During this process, the flexible protective ring 106 on the outer wall of the transmission support fixing rod 105 contacts the inner wall of the steel pipe, which reduces frictional damage and ensures the stability of the detection mechanism inside. When the rotating detection mechanism 100 inside the pipe extends into the steel pipe, the rotating mounting seat 111 drives the annular mounting seats 107 on both sides to rotate. The annular connecting limit plate 108 rotates synchronously in the limit plate rotation embedding groove 112. The annular limit plate separator 114 between the two sets of annular connecting limit plates 108 effectively avoids mutual interference during rotation. The first detection sensor 109 on the sensor mounting ring 110 starts to work, detecting the zinc layer thickness, surface defects and zinc layer adhesion of the inner wall of the steel pipe in real time. The pipe inner wall position detection head 113 continuously feeds back the position coordinates of the detection mechanism to ensure no detection blind spots. The detection data is transmitted to the external data processing terminal in real time through the data transmission pipeline 101.

[0025] In some embodiments, such as Figures 1-3 and Figure 5 As shown, an external detection mechanism moving part 400 is fixed to the top of the overall support frame 6. The external detection mechanism moving part 400 includes a mounting top plate 401, which is fixed to the top of the overall support frame 6. A moving groove 402 is opened on the bottom surface of the mounting top plate 401. A control moving seat 403 is slidably connected in the moving groove 402. The control moving seat 403 is electrically connected to a synchronous moving control component 404. The synchronous moving control component 404 is used to control the moving trajectory of the control moving seat 403 to ensure that its moving speed is synchronized with the transport speed of the transport pipeline mechanism 300. A moving part is fixed on the control moving seat 403. The movable action connector 405 is connected to an external pipeline detection mechanism 500 at one end away from the control movable seat 403. The external pipeline detection mechanism 500 includes an annular frame 501, which is connected to the control movable seat 403 via the movable action connector 405. Adjustable telescopic blocks 502 are evenly distributed on the inner side of the annular frame 501. A second detection sensor 503 is installed at the end of the adjustable telescopic block 502. The adjustable telescopic block 502 can adjust its length according to the outer diameter of the galvanized steel pipe body 7, so that the second detection sensor 503 always maintains the optimal detection distance with the outer wall of the steel pipe. The second detection sensor 503 is connected to a first information transmission line 504. The end of the first information transmission line 504 away from the second detection sensor 503 passes through the inside of a line sleeve 505 and is connected to the second information transmission line 506 inside the line sleeve 505. The line sleeve 505 is used to protect the information transmission line and prevent it from being damaged. The end of the second information transmission line 506 away from the first information transmission line 504 is connected to an information processing integration chamber 507. The information processing integration chamber 507 is connected to an external data processing terminal for integrating the detection data transmitted by the first detection sensor 109 and the second detection sensor 503 and generating a detection report to be fed back to the external terminal.

[0026] When using, such as Figures 1-3 , Figure 5 and Figure 7As shown, when the galvanized steel pipe body 7 moves under the drive of the transport pipeline mechanism 300, the synchronous movement control component 404 controls the moving seat 403 to move along the moving groove 402 on the bottom surface of the mounting top plate 401. Its moving speed is consistent with the steel pipe transport speed, ensuring that the pipeline external inspection mechanism 500 always surrounds the outside of the steel pipe for synchronous inspection. Simultaneously, the length of the adjustable telescopic block 502 inside the annular frame 501 is adjusted according to the outer diameter of the steel pipe to maintain the optimal detection distance between the second detection sensor 503 and the outer wall of the steel pipe, avoiding the impact on detection accuracy due to excessive or insufficient distance. The second detection sensor 503 detects the zinc layer thickness and surface defects on the outer wall of the steel pipe. The detection data is transmitted to the line sleeve 505 through the first information transmission line 504. After docking with the second information transmission line 506, it is sent to the information processing integration chamber 507. The information processing integration chamber 507 integrates the data transmitted by the internal first detection sensor 109 and the external second detection sensor 503, removes redundant information and abnormal data, generates a complete detection report, and feeds it back to the external data processing terminal. Staff can view the detection results in real time and mark unqualified products. After processing and inspection, the propulsion transmission mechanism 200 drives the transmission shaft 204 to rotate in the opposite direction, and the propulsion spiral blade 202 generates a reverse thrust, which smoothly pulls the internal rotating inspection mechanism 100 out of the galvanized steel pipe body 7. The transport pipeline mechanism 300 then transports the inspected steel pipe to the next station, completing one inspection process. This device effectively improves the accuracy and efficiency of galvanized steel pipe quality inspection through internal and external synchronous inspection, automated propulsion and data integration. It is compatible with steel pipes of different specifications and meets the needs of large-scale production. (The first inspection sensor 109 and the external second inspection sensor 503 are both composed of an eddy current thickness sensor (used to detect zinc layer thickness), a laser micro-camera (used to capture surface scratches, bubbles and other defects), and an ultrasonic probe (used to evaluate the bonding force between the zinc layer and the substrate through echo signals).

[0027] In further preferred solutions, such as Figure 5 In addition to connecting to the rotating mounting base 111, the end of the transmission support fixing rod 105 can also be hinged to an adaptive support arm according to actual operating conditions. The adaptive support arm embeds a pressure sensor and a miniature linear motor. The miniature linear motor pushes the adaptive support arm, causing its end rollers to gently press against the inner wall of the steel pipe. Multiple pressure sensors provide real-time pressure feedback to an external data processing terminal, which analyzes and dynamically adjusts the thrust of the miniature linear motor to ensure the detection mechanism remains centered on the steel pipe, achieving active centering. The overall structure allows it to adapt to minor non-roundness changes in the inner wall of the steel pipe and completely eliminates vibration, providing a stable platform for high-precision detection.

[0028] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
