Description

Technical Field

[0001] This invention belongs to the field of testing equipment, and in particular relates to a testing device for pressure pipelines. Background Technology

[0002] Pressure pipelines refer to all pipelines that withstand internal or external pressure, regardless of the medium inside. They are a part of a larger pipeline system used for transporting, distributing, mixing, separating, discharging, metering, controlling, and stopping fluid flow. These pipelines are assemblies composed of pipes, fittings, flanges, bolted connections, gaskets, valves, other components or pressure-bearing parts, and supports. During the installation of pressure pipelines, to improve efficiency, construction companies often pre-weld parts of the pipelines in the storage facility. After welding, to ensure safety, ultrasonic testing is required. However, in practice, testing personnel have found this process inconvenient and inefficient. Utility Model Content

[0003] In view of this, the purpose of this utility model is to propose a testing device for pressure pipelines to solve the problem of inconvenient inspection of weld seams in pressure pipelines, so as to at least partially solve the problems in related technologies.

[0004] To achieve the above objectives, the technical solution created by this utility model is implemented as follows:

[0005] A pressure pipeline testing device, comprising:

[0006] A shelf with a storage section for holding the items to be tested;

[0007] A stop mechanism is provided on the shelf and located downstream of the shelf section along the conveying direction of the item to be tested, for stopping the item to be tested placed on the shelf section;

[0008] A fixing mechanism is provided on the shelf and located upstream of the shelf section along the conveying direction of the item to be tested, for fixing the item to be tested placed on the shelf section;

[0009] The shelf includes a first load-bearing plate and a support column;

[0010] The first support plate is provided with the placement part, and there are multiple support columns, which are all spaced apart at the edge of the lower surface of the first support plate to support the first support plate and the test piece placed on the placement part.

[0011] Furthermore, the placement section is configured with a plurality of conveying rollers spaced apart along the length of the first support plate. Each conveying roller is fitted with a rubber sleeve and has roller seats at both ends, so that the conveying roller is connected to the first support plate.

[0012] Furthermore, the rubber sleeve includes a first frustum portion, a second frustum portion, and a connecting portion;

[0013] The connecting portion is used to connect the first frustum portion and the second frustum portion. The cross-sectional area of ​​the first frustum portion gradually increases from the connecting portion to the roller seat, and the cross-sectional area of ​​the second frustum portion gradually increases from the connecting portion to the roller seat.

[0014] Furthermore, the shelf also includes a second support plate, which is used to connect the plurality of support columns and is located below the first support plate. The second support plate is provided with a first mounting plate for mounting the stop mechanism and a second mounting plate for mounting the fixing mechanism.

[0015] Furthermore, the stopping mechanism includes a first cylinder and a stopping component;

[0016] The stop member is connected to the output rod of the first cylinder, the first cylinder is connected to the first mounting plate, and the first bearing plate is provided with a first through groove for the stop member to pass through.

[0017] Furthermore, the fixing mechanism includes a second cylinder, a slide rail, a slider, a clamping component, an adapter plate, a push plate, and a connecting rod;

[0018] The output rod of the second cylinder is connected to the push plate. The slide rail is mounted on the second mounting plate. The slider is slidably connected to the slide rail. The end face of the slider away from the slide rail is connected to the adapter plate. The upper end of the adapter plate is connected to the clamping member. The connecting rod is disposed between the push plate and the adapter plate. The adapter plate is provided with a first fixing pin for rotatably connecting the connecting rod. The push plate is provided with a second fixing pin for rotatably connecting the connecting rod. Two sliders are slidably connected on the slide rail. Each slider is connected to the adapter plate for connecting the clamping member. The two clamping members are arranged opposite each other along the length direction of the slide rail to form a clamping and fixing part for clamping and fixing the object to be tested. The first bearing plate is provided with a second through groove for the clamping member to pass through.

[0019] Furthermore, the clamping member has a clamping plate at the end opposite to the adapter plate, and the clamping plate is constructed as a flange plate.

[0020] Furthermore, a gasket is provided at the end of the support column opposite to the first bearing plate.

[0021] Through the above technical solution, the rack supports the test piece, and the combined action of the stop mechanism and the fixing mechanism securely fixes the test piece to the rack. This effectively prevents the test piece from shaking, sliding, or shifting, thus ensuring the stability of the testing process and providing a good testing environment for the inspectors. The rack allows the test piece to be quickly and conveniently transported to the testing position, while the stop mechanism stops and positions the test piece to prevent it from being transported out of the rack. The fixing mechanism quickly secures the test piece. Especially for continuous operation with multiple test pieces, the coordinated action of the stop mechanism and the fixing mechanism effectively solves problems such as unstable fixation and inconvenient operation during the testing process. This not only improves the stability of the testing but also enhances the testing environment, enabling inspectors to perform ultrasonic testing on the test pieces conveniently and efficiently.

[0028] It should be noted that, without conflict, the embodiments and features in the embodiments of this utility model can be combined with each other.

Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0032] Pressure pipelines are piping systems that withstand internal or external pressure, used for the transmission, distribution, and control of fluids. Due to their pressure-bearing nature, these pipelines have extremely high requirements for strength and safety. In actual construction, to improve construction efficiency, contractors often choose to pre-weld parts of the pressure pipeline in the factory. After welding, the welded pressure pipeline can be transported to the construction site. Therefore, to ensure the long-term and stable operation of the pressure pipeline, rigorous non-destructive testing (such as ultrasonic testing) is required after welding to confirm the presence of defects (such as cracks, porosity, slag inclusions, etc.) in the welded area. However, in actual testing, testing efficiency is limited. For example, the storage environment in the factory where pressure pipelines are stored may lead to the pipelines being stacked tightly. The space constraints make it difficult for testing personnel to accurately position the testing equipment in the welded area, increasing the operational difficulty and making the testing process very inconvenient.

[0033] Based on this, in a specific embodiment provided by this utility model, a detection device for pressure pipelines is provided, for reference. Figures 1 to 3 As shown, the pressure pipeline testing device includes: a shelf 1, a stop mechanism 2, and a fixing mechanism 3. The shelf 1 has a placement part for supporting the test piece; the stop mechanism 2 is disposed on the shelf 1 and located downstream of the placement part along the conveying direction of the test piece, for stopping the test piece placed on the placement part; the fixing mechanism 3 is disposed on the shelf 1 and located upstream of the placement part along the conveying direction of the test piece, for fixing the test piece placed on the placement part.

[0034] Through the above technical solution, the shelf 1 carries the test piece, and the combined action of the stop mechanism 2 and the fixing mechanism 3 securely fixes the test piece to the shelf, effectively preventing the test piece from shaking, sliding, or shifting and affecting the accuracy of ultrasonic testing. This ensures stability during the testing process and provides a good testing environment for the testing personnel. The shelf allows the test piece to be quickly and conveniently transported to the testing position, while the stop mechanism 2 stops and positions the test piece to prevent it from being transported out of the shelf. At the same time, the fixing mechanism 3 can quickly fix the test piece. Especially for continuous operation of multiple test pieces, the coordinated action of the stop mechanism 2 and the fixing mechanism 3 effectively solves the problems of unstable fixation and inconvenient operation during the testing process. This not only improves the stability of the testing but also improves the testing environment, enabling the testing personnel to perform ultrasonic testing on the test pieces conveniently and efficiently.

[0035] In some implementations, reference Figure 1 and Figure 2As shown, the shelf 1 includes a first support plate 101 and support columns 103. The first support plate 101 is provided with a storage part, and there are multiple support columns 103. The multiple support columns 103 are spaced apart at the edge of the lower surface of the first support plate 101 to support the first support plate 101 and the test piece placed on the storage part. That is, the multi-point distribution of the support columns 103 ensures that the first support plate 101 can evenly bear the gravity from the test piece, reducing the stress concentration problem caused by single-point force, thereby improving the overall load-bearing capacity of the shelf 1, making it less prone to tipping over or deformation, and ensuring that the shelf 1 remains stable during the testing process.

[0036] In some implementations, reference Figure 1 and Figure 2 As shown, the placement section is configured with a plurality of conveying rollers 4 spaced apart along the length of the first bearing plate 101 for supporting and conveying the workpiece to be tested. Each conveying roller 4 is fitted with a rubber sleeve 6, which increases the surface friction and protects the outer wall of the workpiece from damage. At the same time, both ends of the conveying roller 4 are connected to the first bearing plate 101 through roller seats 5, thereby ensuring that the conveying roller 4 can rotate smoothly and support the workpiece to be tested.

[0037] In some embodiments, the conveying roller 4 enables the test piece to move efficiently and conveniently along the length of the first bearing plate 101, facilitating the transport of the test piece to the designated testing position by the testing personnel. This simplifies the transport operation of the test piece and effectively reduces the labor intensity of the testing personnel. At the same time, the rubber sleeve 6 fitted on the conveying roller 4 has good flexibility and anti-slip properties, which can effectively protect the outer wall of the test piece and prevent it from being scratched or worn due to direct contact with the hard roller during transport. It can also protect the conveying roller 4, reduce the wear of the conveying roller 4, and extend the service life of the conveying roller 4. Furthermore, the rubber sleeve 6 can also absorb a certain amount of vibration or impact, thereby reducing damage to the structure of the test piece during transport.

[0038] In some implementations, reference Figure 1 and Figure 2As shown, the rubber sleeve 6 includes a first frustum portion 601, a second frustum portion 602, and a connecting portion 603. The connecting portion 603 connects the first frustum portion 601 and the second frustum portion 602. The cross-sectional area of ​​the first frustum portion 601 gradually increases from the connecting portion 603 to the roller seat 5, and the cross-sectional area of ​​the second frustum portion 602 gradually increases from the connecting portion 603 to the roller seat 5. This allows the rubber sleeve 6 to provide a gradually increasing support area when in contact with the workpiece to be tested, thereby improving the stability of the workpiece and preventing it from sliding or tilting during transport or testing. At the same time, the connecting portion 603, located in the middle position, can provide additional positioning for the workpiece to be tested, preventing it from shifting during displacement.

[0039] In some embodiments, since the cross-sectional area of ​​the first frustum portion 601 and the second frustum portion 602 gradually increases (in the direction from the connecting portion 603 to the roller seat 5), the rubber sleeve 6 can adapt to test pieces of different diameters. That is, whether it is a pressure pipe with a smaller diameter or a pressure pipe with a larger diameter, it can obtain good support through the conical structure of the rubber sleeve 6, which significantly improves the versatility of the equipment. At the same time, the first frustum portion 601 and the second frustum portion 602, which are arranged opposite to each other along the length direction of the connecting portion 603, can naturally position the test piece (the pressure pipe to be tested after welding) to the optimal position of the rubber sleeve 6 (the connecting portion 603 is in the middle) when placed, reducing the need for manual adjustment and significantly speeding up the transport and test preparation of the test piece.

[0040] In some implementations, reference Figures 1 to 2 As shown, the shelf 1 also includes a second support plate 102. The second support plate 102 is used to connect multiple support columns 103 and is located below the first support plate 101. That is, the second support plate 102 can further enhance the stability of the overall structure of the shelf 1. In addition to enhancing stability, the second support plate 102 is also provided with a first mounting plate 7 for installing the stop mechanism 2 and a second mounting plate 8 for installing the fixing mechanism 3.

[0041] Meanwhile, the first mounting plate 7 and the second mounting plate 8 on the second bearing plate 102 provide stable mounting positions for the stop mechanism 2 and the fixing mechanism 3, respectively, ensuring that the functions of the stop mechanism 2 and the fixing mechanism 3 do not interfere with each other, and providing independent working space for their respective operation.

[0042] Furthermore, by installing the stop mechanism 2 on the first mounting plate 7 and the fixing mechanism 3 on the second mounting plate 8, the stop mechanism 2 and the fixing mechanism 3 can be prevented from being installed on the first bearing plate 101, reducing obstacles in the inspection area, optimizing the space for inspection operations, and facilitating the inspection personnel to quickly and efficiently perform ultrasonic inspection on the welded pressure pipeline.

[0043] In some implementations, reference Figure 2 As shown, the stop mechanism 2 includes a first cylinder 201 and a stop member 202. The first cylinder 201 is connected to the first mounting plate 7, and the stop member 202 is connected to the output rod of the first cylinder 201. When ultrasonic testing is required on the workpiece to be tested (a pressure pipe that needs to be tested after welding), the testing personnel can control the first cylinder 201 to extend the output rod of the first cylinder 201, and cause the stop member 202 and part of the output rod of the first cylinder 201 to extend through the first through groove 1011 to the top of the first bearing plate 101 and stop the workpiece to be tested.

[0044] In some implementations, reference Figure 1 and Figure 3 As shown, the fixing mechanism 3 includes a second cylinder 301, a slide rail 302, a slider 303, a clamping member 304, a connecting plate 305, a push plate 306, and a connecting rod 307. The output rod of the second cylinder 301 is connected to the push plate 306. The slide rail 302 is mounted on the second mounting plate 8 and is located above the push plate 306. The slider 303 is slidably connected to the slide rail 302. The end face of the slider 303 facing away from the slide rail 302 is connected to the connecting plate 305. The upper end of the connecting plate 305 is connected to the clamping member 304. The connecting rod 307 is located between the push plate 306 and the connecting plate 305. The connecting plate 305 has a first fixing pin 308 for rotatably connecting the connecting rod 307. The push plate 306 is provided with a second fixing pin 309 for rotatably connecting the connecting rod 307. The two ends of the connecting rod 307 are respectively provided with a first insertion hole for inserting the first fixing pin 308 and a second insertion hole for inserting the second fixing pin 309. Two sliders 303 are slidably connected on the slide rail 302. Each slider 303 is connected with a transition plate 305. The clamping member 304 is connected to the slider 303 through the transition plate 305. The two clamping members 304 are arranged opposite to each other along the length direction of the slide rail 302 to form a clamping and fixing part for clamping and fixing the test piece. When the test piece is stopped and limited by the stop mechanism 2, the two clamping members 304 clamp and fix the test piece from both sides of the test piece.

[0045] In some implementations, reference Figure 1 As shown, the first support plate 101 is provided with a second through groove 1012 for the clamping member 304 to pass through. The second through groove 1012 provides a channel for the clamping member 304 to pass through the first support plate 101, so that the clamping member 304 can extend from below to above the first support plate 101 and clamp and fix the test piece.

[0046] Exemplary description of fixing mechanism 3: Refer to Figure 3As shown, the inspector can control the extension or retraction of the output rod of the second cylinder 301 to release or fix the two clamping parts 304 to be inspected. Specifically, when the output rod of the second cylinder 301 retracts, the output rod of the second cylinder 301 moves down, thereby driving the push plate 306 to move down. When the push plate 306 moves down, the ends of the two connecting rods 307 away from the push plate 306 move closer to each other, thereby causing the connecting rods 307 to drive the two sliders 303 to move closer to each other. Similarly, the sliders 303 simultaneously drive the two clamping parts 304 to move closer to each other and clamp the workpiece to be inspected.

[0047] refer to Figure 3 As shown, when the output rod of the second cylinder 301 extends, the output rod of the second cylinder 301 moves upward, thereby driving the push plate 306 to move upward. When the push plate 306 moves upward, the ends of the two connecting rods 307 away from the push plate 306 move away from each other, thereby causing the connecting rods 307 to drive the two sliders 303 to move away from each other, and the sliders 303 simultaneously drive the two clamping parts 304 to move away from each other. As the two clamping parts 304 move away from each other, the clamping parts 304 gradually loosen their fixation on the test piece.

[0048] In some implementations, reference Figure 1 and Figure 3 As shown, the clamping member 304 has a clamping plate 9 at one end away from the adapter plate 305, and the clamping plate 9 is constructed as a flange plate. The flange plate can be used to connect the clamping block. The clamping block has a clamping surface that can fit with the outer surface contour of the workpiece to be tested. By increasing the contact area with the workpiece to be tested through the clamping block, local stress concentration is reduced and the fixing effect is improved. At the same time, a rubber pad can be installed on the clamping surface of the clamping block to further improve the friction between the clamping surface and the workpiece to be tested, effectively preventing the workpiece to be tested from sliding or loosening during testing or transportation.

[0049] Meanwhile, the rubber pad layer on the clamping surface is soft and can absorb a certain amount of clamping force, avoiding scratches, indentations or other damage to the surface of the workpiece due to the rigid structure of the clamping block during the clamping process. It is especially suitable for workpieces with smooth surfaces or special coatings.

[0050] Furthermore, the clamping blocks installed on the flange plate can be replaced according to actual needs, so that the clamping components 304 can be adapted by replacing the clamping blocks, thereby improving the versatility and flexibility of the device.

[0051] In some implementations, reference Figure 1 As shown, a gasket 1031 is provided at the end of the support column 103 away from the first bearing plate 101. The gasket 1031 can effectively disperse the pressure of the support column 103, thereby reducing the risk of the support column 103 tipping over due to excessive concentrated stress.

[0052] For example, a rubber pad 1031 is installed at the end of the pad 1031 near the ground. The rubber pad 1031 increases the friction, further preventing the support column 103 from moving on the smooth ground or other contact surfaces, and improving the overall stability of the shelf 1.

[0053] In some embodiments, for the inspection of multiple items to be inspected, a first conveyor belt and a second conveyor belt can be provided at the upper end of the inspection device. The first and second conveyor belts are each equipped with a corresponding robot or gantry crane. The first and second conveyor belts are arranged opposite each other along the length of the shelf 1. Along the conveying direction of the items to be inspected, the items to be inspected pass through the first conveyor belt, the shelf 1 and the second conveyor belt in sequence. Specifically, the items to be inspected are transported to the first conveyor belt by the robot or gantry crane, and then transported to the shelf 1 by the first conveyor belt. After that, the items to be inspected are fixed by the stop mechanism 2 and the fixing mechanism 3. The inspectors inspect the items to be inspected by the ultrasonic flaw detector. After the inspection is completed, the inspected pressure pipes are transported to the second conveyor belt, and according to the inspection results, they are classified and placed by the robot or gantry crane.
