Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of steel pipe processing, in particular to a detection device for production and processing of precision steel pipes. Background Art
[0002] During the production and processing of precision steel pipes, inspecting the surface quality of the pipes is a key step in ensuring product performance. However, existing inspection technologies have significant shortcomings in batch inspection and are unable to meet the needs of modern industrialized production.
[0003] Currently, most steel pipe inspection methods rely primarily on manual visual inspection or single-pipe inspection equipment. Manual visual inspection is not only inefficient but also susceptible to operator experience and fatigue, resulting in unstable test results. Furthermore, manual inspection cannot be automated or performed continuously, making it difficult to meet the demands of large-scale production. While existing single-pipe inspection equipment has improved detection accuracy to a certain extent, its efficiency remains low and it is unable to inspect multiple steel pipes simultaneously, making the inspection process cumbersome and time-consuming.
[0004] In practice, precision steel pipes are typically produced in large batches, and traditional testing methods cannot keep pace with the production pace. However, existing testing equipment is mostly limited to individual steel pipes, and cannot perform simultaneous or continuous testing of multiple pipes. This not only increases testing costs but also extends production cycles, severely impacting production efficiency.
[0005] In summary, the prior art lacks a device that can quickly and batch-detect the surface quality of precision steel pipes. Summary of the Invention
[0006] In view of the shortcomings of the existing technology, the present invention provides a detection device for the production and processing of precision steel pipes, which solves the problem mentioned in the background technology that the existing detection device has low efficiency and cannot achieve automated and continuous operation.
[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions: A detection device for the production and processing of precision steel pipes, comprising:
[0008] soaking pools;
[0009] A controller is installed on one side of the soaking tank;
[0010] Also includes:
[0011] A conveying mechanism, electrically connected to the controller, installed inside the immersion tank, and used for conveying the steel pipe;
[0012] A pressure measuring mechanism, installed outside the immersion tank, for testing the pressure of the steel pipe;
[0013] The detection mechanism is located above the immersion tank and connected to the top of the immersion tank, and is used for detecting the outer wall of the steel pipe.
[0014] Preferably, the conveying mechanism includes a first motor, which is installed on one side of the immersion tank by bolts, and a transmission shaft is mounted on the outside of the output end of the first motor, and the transmission shaft is connected to the conveyor belt. The surface of the conveyor belt is provided with a convex structure, and the convex structures on the surface of the conveyor belt are distributed at equal intervals; the conveying mechanism drives the transmission shaft through the first motor, thereby driving the conveyor belt to move. The equidistant convex structures on the surface of the conveyor belt can effectively clamp and stably convey the steel pipe, ensuring that the steel pipe moves accurately during the detection process, avoiding detection errors caused by unstable transportation, wherein a sensor is provided inside the immersion tank to feedback the real-time position of the steel pipe.
[0015] Preferably, the pressure measuring mechanism includes a sealing assembly and a pressurizing assembly. The sealing assemblies are installed on both sides of the immersion tank. The sealing assemblies are used to seal the two ends of the steel pipe. The sealing assembly is connected to the pressurizing assembly. The pressurizing assembly is installed on the outside of the immersion tank. The pressurizing assembly is used to perform pressurized testing on the inside of the steel pipe. Through the synergistic effect of the sealing assembly and the pressurizing assembly, the pressure measuring mechanism can effectively seal the two ends of the steel pipe and inject high-pressure gas into the interior of the steel pipe for pressurized testing. The sealing assembly ensures that the steel pipe will not leak during the testing process, and the pressurizing assembly accurately controls the air pressure to accurately test the compressive performance of the steel pipe, thereby effectively detecting whether the steel pipe has cracks or damage, thereby improving the accuracy and reliability of the test.
[0016] Preferably, the sealing assembly includes a first hydraulic cylinder, which is mounted on the surface of the immersion tank by bolts, and a first slider is mounted on the telescopic end of the first hydraulic cylinder, and a first sealing block is mounted on the top of the first slider, and the first sealing block is rotatably connected to the first slider. There are multiple first sealing blocks, and the first sealing blocks are connected to each other by belt transmission. One end of the first sealing block is in a contraction-shaped structure, and the surface of the first sealing block is made of rubber. The interior of the first sealing block is connected to the output end of the second motor by splines, and the second motor is mounted on the surface of the immersion tank by bolts; the sealing assembly pushes the first slider to move through the telescopic action of the first hydraulic cylinder, thereby driving the first sealing block to accurately contact the two ends of the steel pipe. The rubber surface of the first sealing block can effectively fit the steel pipe to form a good sealing effect and prevent gas leakage. Multiple first sealing blocks are connected by belt transmission to ensure that they can move synchronously under the drive of the second motor to achieve simultaneous sealing of multiple steel pipes.
[0017] Preferably, the pressurizing component includes a second hydraulic cylinder, which is installed on one side of the immersion tank by bolts. The telescopic end of the second hydraulic cylinder is provided with a second slider, and the surface of the second slider is rotatably connected to the second sealing block. There are multiple second sealing blocks distributed in a straight line with equal spacing. One end of the second sealing block is provided with a hole groove connected to the interior, and the second sealing block is connected to the interior of the second slider. The interior of the second slider is a hollow structure. The interior of the second slider is connected to the connecting pipe at the other end, and the connecting pipe is connected to the air pump at the other end. The pressurizing component pushes the second slider to move through the telescopic action of the second hydraulic cylinder, thereby driving the second sealing block to be in close contact with the steel pipe, ensuring that the air path inside the steel pipe is connected to the outside. The equally spaced distribution design of the second sealing block can pressurize multiple steel pipes at the same time, thereby improving the detection efficiency. The hole groove and hollow structure design inside it enable the air pump to inject high-pressure gas into the interior of the steel pipe through the connecting pipe, thereby realizing pressurized detection of the interior of the steel pipe.
[0018] Preferably, the detection mechanism includes a vacuum component, an infrared detection component and a sealing cover. The infrared detection component is provided in multiple groups, and each group of the infrared detection components corresponds to a steel pipe. The infrared detection component is located above the sealing cover, and both ends of the sealing cover are connected to the immersion tank. A vacuum component is installed on the top of one end of the sealing cover, and the vacuum component is connected to the inside of the sealing cover. The detection mechanism realizes efficient and accurate detection of the surface quality of the steel pipe through the synergistic effect of the vacuum component, the infrared detection component and the sealing cover. The vacuum component can evacuate the inside of the sealing cover to a vacuum state, allowing the liquid in the immersion tank to enter the sealing cover, providing a stable environment for detection. The design of the sealing cover isolates the detection area from the outside world, ensuring that the detection process is not disturbed by the outside world. At the same time, the partition structure inside it can separate multiple steel pipes to achieve independent detection. The multiple groups of infrared detection components can correspond to multiple steel pipes, and the displacement changes of the steel pipe surface are monitored in real time by the infrared distance sensor, thereby accurately detecting the curvature defects of the steel pipe surface.
[0019] Preferably, one end of the bottom of the sealing cover is located inside the immersion tank, and the top of the sealing cover is in a sloped structure. A partition is provided inside the sealing cover, and the partition divides the inside of the sealing cover into a plurality of cavities, and each cavity corresponds to a steel pipe; one end of the bottom of the sealing cover extends to the inside of the immersion tank, which can effectively utilize the liquid resources in the immersion tank. Under the action of the vacuum component, the liquid in the immersion tank can be drawn into the sealing cover to form a liquid level detection environment. This design not only saves the amount of liquid used, but also ensures a stable supply of liquid during the detection process, avoiding detection failure due to insufficient liquid; the sloped structure at the top of the sealing cover helps to evenly distribute and quickly discharge the air. When air enters the sealing cover, the sloped structure can guide the air to flow smoothly to the top of the sealing cover, accumulate at the top, and then be detected by the liquid level sensor, wherein the liquid medium can be oil-immersed, which can reduce the effects of corrosion and rust on the steel pipe.
[0020] Preferably, the infrared detection assembly includes a bracket, wherein one bottom end of the bracket is connected to the sealing cover, one top end of the bracket is connected to both ends of a connecting plate, a plurality of micro switches are embedded within the connecting plate, the bottom of the connecting plate is connected to a connecting block via a telescopic rod, a spring is disposed between the bottom of the connecting plate and the connecting block, one end of the connecting block is connected to one side of a slide, a plurality of slides are linearly and evenly spaced, the slides are in sliding contact with the sealing cover, a rubber ring is disposed between the slides and the sealing cover, one top end of the slide is rotatably connected to the detection plate, a torsion spring is disposed between the slides and the detection plate, a through hole is defined within the detection plate, and an infrared distance sensor is mounted on one side of the bracket, the infrared distance sensor being aligned with the through hole within the detection plate, a roller is rotatably connected to one bottom end of the slide, one bottom end of the roller contacts the surface of the steel pipe; the roller contacts the surface of the steel pipe and is capable of rolling as the steel pipe rotates. When the steel pipe surface is curved or otherwise uneven, the roller moves up and down accordingly, driving the connecting plate up and down via the slide, thereby changing the relative position between the infrared distance sensor and the detection plate. This dynamic detection mechanism can monitor changes in the surface of the steel pipe in real time and accurately capture the defect location even when the steel pipe is rotating at high speed. The micro switch can also use a micro cylinder, which can be used to push the detection plate.
[0021] Preferably, the vacuum assembly includes a vacuum pump, which is connected to the inside of the sealing cover. A liquid level sensor is installed on the top of the sealing cover. There are multiple liquid level sensors, and each liquid level sensor corresponds to an independent cavity inside the sealing cover. The liquid level sensor is connected to the controller signal. The vacuum pump is connected to the inside of the sealing cover and can extract the air in the sealing cover to form a vacuum environment. This allows the liquid in the immersion pool to be sucked into the sealing cover to form a stable liquid level. The setting of the liquid level sensor can monitor the liquid level changes of each independent cavity in the sealing cover in real time to ensure that the liquid level reaches the preset initial line. This precise liquid level control and monitoring mechanism can provide a stable environment for the detection process and avoid misjudgment due to liquid level fluctuations. A solenoid valve is provided at one end of the vacuum pump to cut off the connection between the sealing cover and the outside when the liquid level reaches the initial line.
[0022] The present invention provides a detection device for the production and processing of precision steel pipes. It has the following beneficial effects:
[0023] When operating this inspection device for precision steel pipe production and processing, the steel pipe is first placed on the sloped structure at one end of the immersion tank. Driven by the first motor, the conveyor belt moves the steel pipe sequentially between the first and second sealing blocks. Subsequently, the first and second hydraulic cylinders work together to push the first and second sealing blocks to seal the ends of the steel pipe. Then, the vacuum pump starts, evacuating the interior of the sealing cover to a vacuum state, causing the liquid in the immersion tank to be drawn into the sealing cover through the vacuum effect. The liquid level sensor monitors the changes in the liquid level in the sealing cover in real time to ensure that the liquid level reaches the preset initial line.
[0024] In this state, the air pump injects high-pressure air into the second slider through the connecting pipe. The air enters the steel pipe through the through hole at one end of the second sealing block, and performs internal pressurization testing on the steel pipe to evaluate the pressure resistance of the steel pipe. Subsequently, the second motor starts, driving the first sealing block to rotate, thereby rotating the steel pipe in a sealed state. During the rotation of the steel pipe, if there are cracks or damage on the surface of the steel pipe, the high-pressure air inside the steel pipe will be quickly discharged from the cracks, and bubbles will form in the liquid in the sealing cover and float up, causing the liquid level in the corresponding cavity in the sealing cover to drop. The liquid level sensor can accurately monitor this liquid level change and feed back the signal to the controller in real time. Based on the feedback signal, the controller determines whether there are defects on the surface of the steel pipe, thereby realizing rapid batch detection of multiple steel pipes, effectively identifying the damage on the surface of the steel pipe, and ensuring the efficiency and accuracy of the detection.

[0043] Example 3:
[0044] See also Figures 1-10 , the embodiment of the present invention provides a technical solution: a detection device for the production and processing of precision steel pipes, the infrared detection component includes a bracket 502, one end of the bottom of the bracket 502 is connected to the sealing cover 501, the top end of the bracket 502 is connected to the two ends of the connecting plate 503, a plurality of micro switches 504 are embedded in the connecting plate 503, the bottom of the connecting plate 503 is connected to the connecting block 506 through a telescopic rod, a spring 505 is provided between the bottom of the connecting plate 503 and the connecting block 506, one end of the connecting block 506 is connected to one side of the slide 507, and the slide 507 is straight and equidistant. There are multiple sliders 507 distributed in a pitch shape, the sliders 507 are in sliding contact with the sealing cover 501, and a rubber ring is provided between the sliders 507 and the sealing cover 501. One end of the top of the slider 507 is rotatably connected to the detection plate 508, and a torsion spring is provided between the slider 507 and the detection plate 508. A through hole is opened inside the detection plate 508, and an infrared distance sensor 509 is installed on one side of the bracket 502. The infrared distance sensor 509 is aligned with the through hole inside the detection plate 508. One end of the bottom of the slider 507 is rotatably connected to the roller 511, and one end of the bottom of the roller 511 is in contact with the surface of the steel pipe;
[0045] In this embodiment, the slide plate 507 can be pushed downward by the action of the spring 505, so that the slide plate 507 can drive the roller 511 to move downward, and the roller 511 can fit the surface of the steel pipe. At the same time, the holes and grooves inside the multiple detection plates 508 will be aligned with each other. The laser emitted by the infrared distance sensor 509 can pass through the holes and grooves inside the multiple detection plates 508. When the steel pipe rotates, when the surface bends, it will trigger the roller 511 to move up and down. When the roller 511 moves up and down, it can drive the connecting plate 503 to move up and down through the slide plate 507. When the connecting plate 503 moves up and down, the holes and grooves inside each other will be misaligned, thereby causing the infrared distance sensor 509 to move upward and downward. The emitted laser will be obstructed, and the distance will be fed back to the controller 2 through the infrared distance sensor 509. The bending position of the steel pipe surface can be quickly determined based on the distance, and then the detection plate 508 is pushed to one side through the micro switch 504 to prevent the dislocated detection plate 508 from obstructing the laser of the infrared distance sensor 509, so that the infrared distance sensor 509 can detect the next bending point on the steel pipe surface. In this way, the curvature of multiple steel pipe surfaces can be detected in batches until the distance fed back by the infrared distance sensor 509 can directly detect that it exceeds the length of the steel pipe, and then it can be directly determined that there is no curvature on the steel pipe surface, which is conducive to rapid and accurate detection of the curvature of the steel pipe surface in batches.
[0046] The overall workflow of the testing device for precision steel pipe production and processing in this solution is as follows:
[0047] The steel pipe to be tested is placed on the sloped structure at one end of the immersion tank 1. The first motor 301 is activated, driving the conveyor belt 303 via the drive shaft 302. The raised structures on the surface of the conveyor belt 303 can stably clamp the steel pipe and transport it sequentially between the first sealing block 403 and the second sealing block 406.
[0048] The first hydraulic cylinder 401 and the second hydraulic cylinder 405 respectively push the first sealing block 403 and the second sealing block 406 toward the steel pipe. The rubber surfaces of the first and second sealing blocks 403 and 406 fit tightly against the ends of the steel pipe, creating a sealed environment. The first sealing block 403 is connected to the second motor 404 via an internal spline, driving the steel pipe.
[0049] Vacuum pump 510 starts, evacuating the interior of sealing enclosure 501. Under the vacuum, the liquid in immersion tank 1 is drawn into sealing enclosure 501. Liquid level sensor 513 monitors the liquid level in each individual cavity within sealing enclosure 501 in real time. When the liquid level reaches a preset initial level, vacuum pump 510 stops, completing liquid filling.
[0050] The air pump 407 injects high-pressure air into the second slider 409 through the connecting pipe 408. The air enters the steel pipe through the through hole at one end of the second sealing block 406. The pressurizing component performs a pressurization test on the steel pipe to evaluate its compressive performance.
[0051] The second motor 404 starts, driving the first sealing block 403 to rotate, thereby rotating the steel pipe in a sealed state. During the steel pipe's rotation, the infrared detection component begins to operate. The roller 511 contacts the surface of the steel pipe. When cracks or damage exist on the surface of the steel pipe, the high-pressure air inside the steel pipe will be rapidly discharged from the cracks, forming bubbles that float to the surface of the liquid in the sealing cover 501, causing the liquid level in the corresponding cavity to drop. After the liquid level sensor 513 detects the change in liquid level, it feeds the signal back to the controller 2.
[0052] Controller 2 receives feedback from liquid level sensor 513 and analyzes the test data. If the liquid level drops below a preset threshold, it determines that the steel pipe surface is damaged or cracked and records the specific location. After the test is complete, controller 2 outputs the test results, identifying qualified and unqualified steel pipes.
[0053] After the inspection is completed, the air pump 407 stops working, the reset device returns the first sealing block 403 and the second sealing block 406 to their initial positions, and the conveyor belt 303 moves the inspected steel pipes out of the inspection area to prepare for the next batch of inspections.
[0054] Through the above process, this solution can realize the automated and continuous detection of precision steel pipes, quickly judge the surface quality of steel pipes in batches, and meet the needs of large-scale production.
[0055] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
