Description

Technical Field

[0001] This invention relates to the field of steel plate flaw detection technology, specifically to an array detection device and method for steel plate flaw detection. Background Technology

[0002] Steel plates are widely used as raw materials for steel processing in various fields, such as pipeline transportation, road and bridge construction, petrochemical industry, etc. However, defects are unavoidable in the steel plate production process. If steel plate defects are misdetected or missed, they may cause serious losses.

[0003] When inspecting steel plates using array-type flaw detection equipment, the steel plate is typically placed on a roller conveyor, and then the arrayed flaw detectors are attached to the surface of the steel plate. A couplant is then sprayed onto the surface, allowing the ultrasonic waves emitted by the flaw detector to penetrate the couplant and detect flaws on the steel plate surface. However, because the detectors are in contact with the steel plate surface, the couplant on the steel plate can lag due to the movement of the steel plate and the obstruction of the detectors. This can cause the couplant to flow backwards between the plate and the steel plate, resulting in uneven layer thickness and flow rate of the couplant between the steel plate and the flaw detectors. This leads to significant fluctuations in the flaw detection signal as it passes through the couplant, making stable detection difficult and causing errors or missed detections, thus affecting the efficiency of the flaw detection process. Summary of the Invention

[0004] The purpose of this invention is to provide an array inspection device and method for steel plate flaw detection, so as to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0006] This invention relates to an array inspection device for steel plate flaw detection, comprising a main body and a conveyor table, and further comprising:

[0007] The guiding mechanism is installed on the side wall of the main body to ensure the uniformity of the couplant layer thickness during steel plate flaw detection.

[0008] An auxiliary mechanism is installed on the side wall of the guide mechanism to prevent excessive shaking during operation of the guide mechanism, which could cause reciprocating fluctuations in the flow of the coupling agent.

[0009] Furthermore, the main body includes:

[0010] The limiting component is installed on the side wall of the main body to ensure stable transport of the steel plate during flaw detection.

[0011] Furthermore, the guiding mechanism includes several fixed frames disposed on the sidewall of the limiting component, and the guiding mechanism also includes:

[0012] The circulation component is installed inside the fixed frame 1.

[0013] Deformation assembly, installed on the side wall of the flow assembly, is used to guide the flow of the coupling agent during steel plate conveying;

[0014] The flexible component is installed on the side wall of the deformable component to prevent the coupling agent from remaining on the side wall of the deformable component during operation.

[0015] Furthermore, the auxiliary mechanism includes a rubber sheet disposed on the side wall of the deformation component, the rubber sheet having a square groove in the middle, and the auxiliary mechanism also includes:

[0016] A rotating assembly is mounted on the side wall of the rubber sheet;

[0017] The movable component is mounted on the side wall of the rotating component.

[0022] The circulation component includes a fixed frame two that is fixedly connected inside the fixed frame one, and a central rod is fixedly connected inside the fixed frame two;

[0023] The internal fixed connection of the second fixed frame has an auxiliary rod;

[0024] The deformation component includes an arc-shaped plate fixedly connected to the outer surface of the central rod. A rectangular frame is provided on the side wall of the arc-shaped plate. An elastic plate is fixedly connected to the inner wall of the rectangular frame away from the fixed frame. The bottom of the elastic plate is inclined. The central rod and the arc-shaped plate are eccentrically positioned.

[0025] The sidewall of the curved plate has several notches and grooves, and the curved plate is connected to the notches and grooves by a thin sheet so that the curved plate can be bent later.

[0026] Furthermore, the flexible component includes an elastic sheet fixedly connected to the side of the arc-shaped plate near the auxiliary rod, and the side of the elastic sheet near the arc-shaped plate is fixedly connected with several flexible layers;

[0027] Several flexible layers are arranged in pairs symmetrically around the notch groove. Several groups of flexible layers are arranged at equal distances. Several small holes are opened on the side wall of the elastic sheet. The small holes allow the coupling agent to flow slowly outward through the small holes, reducing the accumulation of coupling agent between two flexible layers when the flaw detector is not working.

[0028] Furthermore, one end of the rubber sheet near the fixed frame is fixedly connected to the side wall of the arc plate, a curved plate is fixedly connected to the side wall of the rubber sheet, the rubber sheet is slidably connected between the auxiliary rod and the arc plate, and the bottom of the rubber sheet is semi-circular.

[0029] The rotating assembly includes a conical plate rotatably connected inside the fixed frame 2, with limit plates rotatably connected to both the front and back sides of the conical plate;

[0030] The ends of the two limiting plates furthest from the conical plate are rotatably connected to the side wall of the arc-shaped plate;

[0031] A T-shaped rod is fixedly connected to the side of the conical plate closest to the elastic plate, and the side of the T-shaped rod away from the conical plate is in contact with the side wall of the elastic plate.

[0032] Furthermore, the active component includes an L-plate fixedly connected to the inner wall of the fixed frame two near the limiting plate, and a long rod is rotatably connected between the two L-plates;

[0033] Three connecting plates are fixedly connected to the outer surface of the long rod, and two conical plates are fixedly connected to the side of the three connecting plates near the conical plate;

[0034] The conical plate and the two conical pieces are fitted together.

[0035] Furthermore, a method for using an array inspection device for steel plate flaw detection, the method comprising the following steps:

[0036] S1: Placing the steel plate: First, place the steel plate to be inspected on the surface of the conveyor table, and then install a coupling agent spraying pipe at the front end of the main body and in the middle area of ​​the fixed plate.

[0037] S2: Spraying couplant: Then, multiple flaw detectors and conveyor stations are activated, and couplant is sprayed onto the steel plate surface through the couplant spray pipe, with a certain gap set between the bottom of the arc plate and the steel plate.

[0038] S3: Conveying Flaw Detection: When the conveyor is working, it will carry the steel plate to be conveyed. When the steel plate is being conveyed, multiple flaw detectors will perform flaw detection on the steel plate.

[0039] The present invention has the following beneficial effects:

[0040] 1. In this invention, the coupling agent folded back by the rubber sheet and elastic sheet, along with the coupling agent flowing over the outer surface of the arc-shaped plate, forms a laminar water curtain that reaches and covers the contact area between the flaw detector and the steel plate. This reduces the lag and reverse flow of the coupling agent caused by the probe obstructing the flow of the coupling agent as it flows with the steel plate. Consequently, it ensures uniform flow velocity and layer thickness of the coupling agent between the probe and the steel plate, while improving the stability and accuracy of the array of flaw detectors in flaw detection of the steel plate, thus increasing flaw detection efficiency.

[0041] 2. In this invention, when the couplant flows between the conical plate and the conical blade, the channel between the conical plate and the conical blade can reduce the flow velocity of the couplant. By reducing the flow height and velocity of the couplant laminar water curtain, the situation where air bubbles appear on the couplant on the steel plate and damage the coupling interface is reduced when the couplant falls between the steel plate and the flaw detector due to the high height and high velocity of the couplant water curtain. This ensures the stability of flaw detection while improving the detection efficiency.

[0042] 3. In this invention, when the flexible layer is compressed, the coupling agent inside the flexible layer will be ejected and flow in the direction of the coupling agent through the notch groove. This can reduce the situation where the coupling agent is scraped off by the curved plate during the transport of the steel plate, and the flow of the coupling agent is obstructed due to the curvature of the curved plate, resulting in less coupling agent or drying at the bottom of the flaw detector. This further ensures the integrity and strength of the detection while improving the accuracy of the flaw detection.

[0043] 4. This invention, through the contact between the bending plate and the elastic plate, can display the reset speed of the rubber sheet and the arc plate when the rubber sheet is reset at the top of the arc plate. This reduces excessive shaking of the arc plate and the rubber sheet during steel plate conveying. At the same time, the contact between the bending plate and the elastic plate can also reduce the reverse deformation of the bent part of the rubber sheet when pushed by the coupling agent. This ensures that the coupling agent can flow continuously while ensuring its flow strength and flow stability, thereby further enhancing the reliability and strength of the flaw detection.

[0044] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

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.

[0060] Please see Figure 1 - Figure 11 As shown, the present invention is an array inspection device for steel plate flaw detection, comprising a main body 1 and a conveyor table 4, and further comprising:

[0061] The guide mechanism 2 is installed on the side wall of the main body 1 to ensure the uniformity of the coupling agent layer thickness when inspecting steel plates.

[0062] Auxiliary mechanism 3 is installed on the side wall of guide mechanism 2 to prevent excessive shaking during operation of guide mechanism 2, which would cause reciprocating fluctuations in the flow of coupling agent.

[0063] Entity 1 includes:

[0064] The limiting component 11 is installed on the side wall of the main body 1 to ensure stable conveying of the steel plate during flaw detection.

[0065] The guiding mechanism 2 includes several fixed frames 201 disposed on the side wall of the limiting component 11, and the guiding mechanism 2 also includes:

[0066] Flow component 21 is installed inside the fixed frame 201;

[0067] Deformation component 22 is installed on the side wall of flow component 21 and is used to guide the flow of coupling agent during steel plate conveying;

[0068] Flexible component 23 is installed on the side wall of deformable component 22 to prevent coupling agent from being retained on the side wall of deformable component 22 during operation.

[0069] The auxiliary mechanism 3 includes a rubber sheet 301 disposed on the side wall of the deformation component 22. A square groove is formed in the middle of the rubber sheet 301. The auxiliary mechanism 3 also includes:

[0070] Rotating assembly 31 is mounted on the side wall of rubber sheet 301;

[0071] The movable component 32 is mounted on the side wall of the rotating component 31.

[0072] The limiting component 11 includes two fixing plates 111 fixedly connected to the inner wall of the top of the main body 1, and a limiting roller 112 is rotatably connected to the side of the fixing plate 111 away from the middle of the main body 1;

[0073] A fixing frame 113 is fixedly connected to the top inner wall of the main body 1, and several flaw detectors 114 are fixedly connected to the side wall of the fixing frame 113.

[0074] Several flaw detectors 114 are arranged in pairs at equal intervals.

[0075] The fixing frame is bolted to the side wall of the flaw detector 114;

[0076] The circulation component 21 includes a fixed frame 211 fixedly connected inside the fixed frame 201, and a central rod 212 is fixedly connected inside the fixed frame 211.

[0077] An auxiliary rod 213 is fixedly connected inside the fixed frame 211;

[0078] The deformation component 22 includes an arc-shaped plate 221 fixedly connected to the outer surface of the central rod 212. A rectangular frame 222 is provided on the side wall of the arc-shaped plate 221. An elastic plate 223 is fixedly connected to the inner wall of the rectangular frame 222 away from the fixed frame 201. The bottom of the elastic plate 223 is inclined. The central rod 212 and the arc-shaped plate 221 are eccentrically positioned.

[0079] The sidewall of the arc plate 221 has several notches and grooves. The arc plate 221 is connected to the notches and grooves by a thin sheet so that the arc plate 221 can be bent later. When the surface of the arc plate 221 is curved, the bending of the arc plate 221 will cause the multiple notches on the sidewall of the arc plate 221 to be open. At the same time, when the coupling agent flows through the surface of the arc plate 221, the area between the two flexible layers 232 will store the moving coupling agent.

[0080] The flexible component 23 includes an elastic sheet 231 fixedly connected to the side of the arc plate 221 near the auxiliary rod 213, and a plurality of flexible layers 232 are fixedly connected to the side of the elastic sheet 231 near the arc plate 221.

[0081] Several flexible layers 232 are arranged in pairs symmetrically around the notch groove. Several groups of flexible layers 232 are arranged at equal distances. Several small holes are opened on the side wall of the elastic sheet 231. The small holes allow the coupling agent to flow out slowly through the small holes, reducing the accumulation of coupling agent between two flexible layers 232 when the flaw detector 114 is not working. Since the elastic sheet 231 is inclined on the side wall of the arc plate 221, when the T-shaped rod 313 slides on the side wall of the elastic sheet 231, the T-shaped rod 313 will generate a pushing force on the elastic sheet 231. When the elastic sheet 231 is pushed, it will slide towards the arc plate 221 and squeeze the flexible layer 232.

[0082] One end of the rubber sheet 301 near the fixed frame 201 is fixedly connected to the side wall of the arc plate 221. A curved plate 302 is fixedly connected to the side wall of the rubber sheet 301. The rubber sheet 301 is slidably connected between the auxiliary rod 213 and the arc plate 221. The bottom of the rubber sheet 301 is semi-circular.

[0083] The rotating assembly 31 includes a conical plate 311 rotatably connected inside the fixed frame 211, and limit plates 312 are rotatably connected to both the front and back sides of the conical plate 311.

[0084] The ends of the two limiting plates 312 away from the conical plate 311 are rotatably connected to the side wall of the arc plate 221;

[0085] A T-shaped rod 313 is fixedly connected to the side of the conical plate 311 near the elastic plate 223. The side of the T-shaped rod 313 away from the conical plate 311 is in contact with the side wall of the elastic plate 223. When the conical plate 311 is pushed by the limiting plate 312, the conical plate 311 will rotate downward. At this time, the side wall of the conical plate 311 will separate from the fitted conical piece 322.

[0086] The active component 32 includes an L-plate 321 fixedly connected to the inner wall of the fixed frame 211 near the limiting plate 312, and a long rod is rotatably connected between the two L-plates 321.

[0087] Three connecting plates are fixedly connected to the outer surface of the long rod, and two conical pieces 322 are fixedly connected to the side of the three connecting plates near the conical plate 311.

[0088] The conical plate 311 is fitted into the two conical pieces 322.

[0089] A method for using an array inspection device for steel plate flaw detection, the method comprising the following steps:

[0090] S1: Placing the steel plate: First, place the steel plate to be inspected on the surface of the conveyor table 4, and then install a coupling agent spraying pipe at the front end of the main body 1 and in the middle area of ​​the fixed plate 111.

[0091] S2: Spraying couplant: Then, multiple flaw detectors 114 and conveyor 4 are activated, and couplant is sprayed onto the steel plate surface through the couplant spray pipe, and a certain gap is set between the bottom of the arc plate 221 and the steel plate.

[0092] S3: Conveying Flaw Detection: At the same time, the conveyor table 4 will drive the steel plate to be conveyed when it is working. When the steel plate is being conveyed, multiple flaw detectors 114 will perform flaw detection on the steel plate.

[0093] In use, the steel plate to be inspected is first placed on the surface of the conveyor table 4. Then, a coupling agent spraying pipe is installed at the front end of the main body 1 and in the middle area of ​​the fixed plate 111. Then, multiple flaw detectors 114 and the conveyor table 4 are started. At the same time, coupling agent is sprayed onto the surface of the steel plate through the coupling agent spraying pipe, and a certain gap is set between the bottom of the arc plate 221 and the steel plate. Meanwhile, the conveyor table 4 will drive the steel plate to be conveyed when it is working. When the steel plate is being conveyed, multiple flaw detectors 114 will perform flaw detection on the steel plate.

[0094] When the steel plate is conveyed on the surface of the conveyor table 4, there will be a certain gap between the arc plate 221 and the steel plate. At the same time, the curvature of the bottom of the rubber sheet 301 will come into contact with the surface of the steel plate under the action of the steel plate. At this time, the curved part of the bottom of the rubber sheet 301 will produce a convex deformation in the opposite direction of the steel plate conveying due to the obstruction of the steel plate. Since there is a gap between the bottom of the arc plate 221 and the steel plate, when the steel plate moves the coupling agent, the bottom of the arc plate 221 will scrape off the excess coupling agent on the steel plate when the steel plate moves. This allows some coupling agent to pass through the gap between the steel plate and the arc plate 221, leaving a thin and uniform coupling agent water film. At the same time, the scraped coupling agent will flow along the curvature of the outer surface of the arc plate 221 towards the space between the flaw detector 114 and the steel plate under the push of the subsequent coupling agent flow. Meanwhile, some coupling agent will flow in the opposite direction due to the obstruction of the flaw detector 114. When in motion, the reverse-flowing coupling agent flows to the concave arc surface of the bottom arc surface of the deformed rubber sheet 301 and flows along the arc of the rubber sheet 301 and the elastic sheet 231 to the inclined surface after the conical plate 311 and the conical sheet 322 are closed. It then turns back along the slope of the conical plate 311 to the position of the flaw detector 114. At this time, the coupling agent that turns back through the rubber sheet 301 and the elastic sheet 231 and the coupling agent that flows through the outer surface of the arc plate 221 will form a laminar water curtain that reaches and covers the contact area between the flaw detector 114 and the steel plate. This can reduce the lag and reverse flow of the coupling agent when it flows with the steel plate due to the obstruction of the probe. This can ensure that the flow rate and layer thickness of the coupling agent between the probe and the steel plate are uniform, while improving the stability and accuracy of the flaw detector 114 in the flaw detection of the steel plate and improving the flaw detection efficiency.

[0095] When the hysteresis and reverse flow of the coupling agent, caused by the obstruction of the flaw detector 114, impacts the curved portion at the bottom of the rubber sheet 301, the reverse flow of the coupling agent will cause the curved portion of the rubber sheet 301 to exert a pulling force on the top of the arc plate 221 under the impact of the coupling agent. When the top of the arc plate 221 is subjected to the pulling force of the rubber sheet 301, the arc of the arc plate 221 will undergo a bending deformation. At the same time, the top of the arc plate 221 will slide downward under the pull of the rubber sheet 301, reducing the distance between it and the L plate 321. Simultaneously, when the top area of ​​the arc plate 221 slides downward, the sliding of the top of the arc plate 221 will generate a downward pushing force on the side wall of the conical plate 311 through the limiting plate 312. When the conical plate 311 is pushed by the limiting plate 312, the conical plate 311 will rotate downward. At this time, the side wall of the conical plate 311 will separate from the fitted conical piece 322, presenting... Figure 9 In this state, a misaligned flow channel is formed between the surface of the conical plate 311 and the two conical plates 322. At the same time, when the distance between the top area of ​​the arc plate 221 and the conical plate 311 decreases, the couplant flowing through the arc plate 221 can reduce the couplant flow height. Meanwhile, when the couplant flows between the conical plate 311 and the conical plates 322, the channel between the conical plate 311 and the conical plates 322 can reduce the couplant flow velocity. By reducing the flow height and velocity of the couplant laminar water curtain, the situation where air bubbles appear on the couplant on the steel plate and damage the coupling interface when the couplant falls between the steel plate and the flaw detector 114 due to the high height and high velocity of the couplant water curtain can be reduced. This ensures the stability of flaw detection while improving the detection efficiency.

[0096] When the rubber sheet 301 is impacted by the returning coupling agent and pulls the top area of ​​the arc plate 221, the surface of the arc plate 221 will undergo arc deformation. When the surface of the arc plate 221 bends, the bending of the arc plate 221 will cause multiple notches on the side wall of the arc plate 221 to be open. At the same time, when the coupling agent flows through the surface of the arc plate 221, the area between the two flexible layers 232 will store the moving coupling agent. Meanwhile, when the top area of ​​the arc plate 221 slides downward and pushes the conical plate 311 to rotate through the limiting plate 312, the rotation of the conical plate 311 will drive the T-shaped rod 313 to rotate synchronously. When the T-shaped rod 313 rotates, it will slide on the side wall of the elastic sheet 231. At the same time, since the elastic sheet 231 is inclined on the side wall of the arc plate 221... When the T-shaped rod 313 slides on the side wall of the elastic sheet 231, the T-shaped rod 313 will generate a pushing force on the elastic sheet 231. When the elastic sheet 231 is pushed, it will slide towards the arc plate 221 and squeeze the flexible layer 232. When the flexible layer 232 is squeezed, the coupling agent inside the flexible layer 232 will be sprayed out and flow towards the coupling agent through the notch. This can reduce the situation where the coupling agent is scraped off by the arc plate 221 during the transport of the steel plate. Due to the curvature of the arc plate 221, the flow of the coupling agent is obstructed on the surface of the arc plate 221, resulting in less coupling agent or drying at the bottom of the flaw detector 114. This further ensures the integrity of the detection strength and improves the accuracy of the flaw detection.

[0097] When the curved portion at the bottom of the rubber sheet 301 contacts and bends against the steel plate surface due to the obstruction of the steel plate, the bending plate 302 on the side wall of the curved portion of the rubber sheet 301 will face the elastic plate 223 and contact its inclined surface. At the same time, when the curved portion of the rubber sheet 301 is pushed by the return coupling agent, the curvature of the bottom of the rubber sheet 301 will bend more. Meanwhile, when the bottom of the rubber sheet 301 bends, it will push the inclined surface of the elastic plate 223 through the bending plate 302. At this time, the elastic plate 223 will face the curvature direction of the deformed arc plate 221, thereby enabling the scraped coupling agent body 1 to flow further over the curvature of the arc plate 221 when flowing over the surface of the arc plate 221. Meanwhile, through the contact between the bending plate 302 and the elastic plate 223, the resetting speed of the rubber sheet 301 and the arc plate 221 can be displayed when the rubber sheet 301 is reset at the top of the arc plate 221. This can reduce the excessive shaking of the arc plate 221 and the rubber sheet 301 during steel plate conveying. At the same time, the contact between the bending plate 302 and the elastic plate 223 can also reduce the reverse deformation of the bent part of the rubber sheet 301 when it is pushed by the coupling agent. This can ensure that the coupling agent can flow continuously while ensuring its flow strength and flow stability, thereby further enhancing the reliability and strength of the detection and flaw detection.
