Description

Technical Field

[0001] This invention relates to the field of industrial testing equipment, specifically an integrated device for metallographic inspection and hardness testing of power plant steam pipelines. Background Technology

[0002] Power plant steam pipelines are subjected to high-temperature and high-pressure environments during long-term operation, which alters their metallographic structure and hardness characteristics, thus affecting their safety and service life. To ensure reliable operation of power plant steam pipelines, regular metallographic inspection and hardness testing are essential. The integrated metallographic inspection and hardness testing device for power plant steam pipelines, through its integrated design, can perform both inspections simultaneously, providing crucial information for pipeline condition assessment and facilitating the timely detection of potential problems and preventative maintenance.

[0003] Existing integrated metallographic inspection and hardness testing devices for power plant steam pipelines are typically operated by hand-held tools. First, operators must use hand-held grinding equipment to treat the pipeline surface to ensure the surface conditions are suitable for metallographic inspection. Then, they manually use a hardness tester to measure the pipeline's hardness value. While this hand-held operation method is simple and intuitive, it requires a high level of skill from the operator and is significantly affected by human factors; test results may vary between different operators.

[0004] While existing integrated metallographic inspection and hardness testing devices for power plant steam pipelines can complete the final inspection, they have several shortcomings. First, these devices largely rely on manual adjustment and operation, lacking automated control over the position and angle of the testing equipment. This necessitates frequent adjustments when dealing with pipelines of different specifications and complex conditions, consuming significant time and effort and resulting in low inspection efficiency. Second, manual operation is susceptible to human factors, such as the operator's experience and skill level, making it difficult to guarantee inspection accuracy and consistency, especially when high-precision metallographic inspection and hardness measurement are required. Furthermore, the grinding and connecting components of existing devices are prone to wear and impact during operation, lacking effective elastic adjustment and protection measures. This leads to frequent component replacements, high maintenance costs, and compromises the long-term stability and safety of the equipment. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an integrated device for metallographic inspection and hardness testing of power plant steam pipelines. Through an automated adjustment mechanism and integrated design, this invention achieves automatic control of the position and angle of the testing device, significantly improving testing accuracy and consistency. Simultaneously, the device is equipped with elastic adjustment and protective measures, effectively reducing wear on grinding and connecting components, lowering maintenance costs, and enhancing the stability and safety of the equipment.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an integrated device for metallographic inspection and hardness testing of power plant steam pipelines, comprising:

[0007] The testing mechanism provides support for the entire device and provides an installation environment and space for subsequent mechanisms. The testing mechanism includes a grinding component and two sets of testing instruments for metallographic inspection and hardness testing of the power plant steam pipeline.

[0008] An adjustment mechanism, located inside the detection mechanism, is used to adjust the height and position of the detection mechanism, thereby facilitating the grinding parts and the detection instrument to detect steam pipes at different heights;

[0010] The second drive mechanism is located in the middle of the detection mechanism and is used to adjust the distance between the detector and the gas pipeline, so that the detector can detect the hardness of steam pipelines of different diameters.

[0011] A connecting mechanism, located on the outside of the second drive mechanism, is used to provide the grinding part with a spring-back space, so that the grinding part can retract when it contacts the protruding part of the gas pipeline, avoiding rigid work.

[0014] Preferably, the drive mechanism includes an electric motor, which is fixedly connected to the outer side of one of the arc-shaped plates. A gear is fixedly connected to the output end of the electric motor. Gear rings are fixedly connected to the outer side of the second arc-shaped plate, and both gear rings mesh with the gear. A T-shaped rod is slidably connected to the middle of the second arc-shaped plate. A protrusion is fixedly connected to one end of the T-shaped rod. A circular ring is fixedly connected to the outer periphery of the T-shaped rod. A circular ring is fixedly connected to the inside of the second arc-shaped plate. The T-shaped rod passes through the circular ring fixed inside the second arc-shaped plate. Multiple springs are arranged between the two circular rings. A sprocket is rotatably connected to the inside of the second arc-shaped plate. The sprocket and... A locking assembly is provided between the two arc-shaped plates. One end of the first sprocket has a groove. The T-shaped rod and the protrusion are slidably connected to the middle of the groove. Two second sprockets are rotatably connected inside the second arc-shaped plate. A chain is meshed with the outer periphery of the two second sprockets and the first sprocket. A turntable is fixedly connected to one end of the second sprocket. The turntable is rotatably connected inside the second arc-shaped plate. An eccentric rod is fixedly connected to the other end of the turntable. A connecting belt is sleeved on the outer periphery of the eccentric rod. The connecting belt is slidably connected inside the second arc-shaped plate. A top plate is fixedly connected to the outer side of the connecting belt. The grinding component is located on the side of the top plate away from the connecting belt.

[0015] Preferably, the second drive mechanism includes two sets of covers, which are respectively fixedly connected to the outer sides of the two arc-shaped plates. A second cylinder is fixedly connected inside the cover, and a connecting rod is fixedly connected to the output end of the second cylinder. One set of detectors is fixedly connected to the end of the connecting rod away from the second cylinder.

[0016] Preferably, the connecting mechanism includes a connecting plate, which is fixedly connected to the top plate on the side away from the connecting strip. A second compression spring is fixedly connected to the other side of the connecting plate, and a fixing block is fixedly connected to the other end of the second compression spring. A limit rod is fixedly connected to the side of the fixing block near the connecting plate, and the limit rod is slidably connected to the middle of the connecting plate.

[0017] Preferably, the connecting assembly includes a compression spring three, which is fixedly connected inside the fixing block. The other end of the compression spring three is fixedly connected to a T-shaped plate, which is slidably connected to the middle of the fixing block. A locking block is fixedly connected to the other side of the T-shaped plate. A positioning block is fixedly connected to the side of the grinding part near the top plate. The positioning block and the fixing block are interlocked. A slot is provided in the middle of the positioning block, and the locking block and the slot are interlocked.

[0018] Preferably, the upper side of the support plate has two sliding grooves, and the nut seat is slidably connected to the middle of the sliding grooves.

[0019] Preferably, the fixing block has a positioning groove on the side near the grinding part, and the positioning block is slidably connected to the middle of the positioning groove.

[0020] Preferably, the side of the card block closest to the positioning block is arc-shaped to allow it to move when squeezed, thereby reducing wear and speeding up the connection.

[0021] Working principle: During use, the device is movable by the wheels at the bottom of the support plate. The operator can move the device to the detection position by the handle. The height of the box and the bracket can be adjusted by the drive cylinder, so that the arc plate one and the arc plate two are moved to the same height as the steam pipe. At the same time, the double motor drives two screws with opposite designs to rotate, thereby driving the nut seat to move the two brackets closer or further apart, adjusting the height of the arc plate one and the arc plate two to wrap the steam pipes of different heights.

[0022] The system is designed to rotate the arc-shaped plate by driving the gear and gear ring with an electric motor. This allows the angle and position of the grinding part to be adjusted. At the same time, pressing the T-shaped rod compresses the spring and causes the protrusion to enter the sprocket. The locking assembly closes as the T-shaped rod is pressed. Rotating the T-shaped rod and using the chain causes the sprockets to rotate simultaneously. This causes the turntable and eccentric rod to rotate, and the connecting belt moves the top plate, bringing the grinding part into contact with the gas pipeline. Releasing the T-shaped rod and using the spring causes it to reset, activating the locking assembly. This, combined with the rotation of the arc-shaped plate, allows the surface of the gas pipeline to be ground.

[0023] Secondly, when the grinding part comes into contact with the protruding part of the gas pipeline, the grinding part will drive the fixing block to compress the second compression spring. Under the action of the second compression spring, the grinding part will automatically pop out when there is no pressure, thus avoiding damage caused by hard contact.

[0024] By pressing the T-shaped plate, the compression spring can be compressed three times, and the locking block can be pulled out from the middle of the positioning block, thereby quickly removing the grinding part. The grinding part can be quickly installed by inserting the positioning block. The model of the grinding part can be quickly changed to ensure that the gas pipeline meets the required testing conditions after grinding.

[0025] Finally, by driving cylinder two, the connecting rod is driven to contact the detector with the polished position on the outer periphery of the gas pipeline, thereby completing the metallographic inspection and hardness test of the gas pipeline.

[0026] This invention provides an integrated device for metallographic inspection and hardness testing of steam pipelines in power plants. It features the following:

[0027] Beneficial effects:

[0028] 1. This invention achieves automated adjustment of the grinding parts and the testing instrument through the integrated design of the detection mechanism and the adjustment mechanism. It can quickly adapt to steam pipes of different heights and diameters, improve detection efficiency and operational flexibility, and at the same time ensure stable detection under various pipe surface conditions, thereby improving the consistency and accuracy of the results.

[0029] 2. By setting up a driving mechanism and a connecting mechanism, this invention achieves precise positioning of the workpiece and accurate measurement position adjustment of the testing instrument, reducing the complexity of manual operation and adjustment, significantly improving the accuracy and stability of grinding and hardness testing, and ensuring the high efficiency of testing operations and the reliability of the equipment.

[0030] 3. The present invention provides quick replacement of grinding parts and elastic buffer function through the connection mechanism design, so that the grinding parts can adaptively adjust when encountering protrusions on the pipe surface, avoiding damage caused by hard contact, extending the service life of the grinding parts, reducing downtime, and further improving the safety and maintenance convenience of the device.

[0040] The technical solutions in 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.

[0041] Please see the appendix Figure 1 - Appendix Figure 8 This invention provides an integrated device for metallographic inspection and hardness testing of power plant steam pipelines, comprising:

[0042] The testing mechanism 10 provides support for the entire device and provides an installation environment and space for subsequent mechanisms. The testing mechanism 10 includes a grinding component 107 and two sets of testing instruments 108, which are used to perform metallographic inspection and hardness testing on the steam pipeline of the power plant. By integrating grinding and testing functions, the testing mechanism 10 reduces the preparation time before testing, improves testing efficiency and accuracy, and can operate stably under different pipeline surface conditions, ensuring the consistency of test results.

[0043] The adjustment mechanism 20 is located inside the detection mechanism 10 and is used to adjust the height and position of the detection mechanism 10, so that the grinding part 107 and the detector 108 can detect steam pipes of different heights. The relative position of the grinding part 107 and the detector 108 can be flexibly adjusted through the adjustment mechanism 20 to adapt to steam pipes of different heights, thereby improving the flexibility and application range of the device.

[0044] The drive mechanism 30 is located in the middle of the detection mechanism 10 and is used to adjust the distance between the grinding part 107 and the gas pipeline, so that the grinding part 107 can perform metallographic inspection on steam pipelines of different diameters. The drive mechanism 30 adapts to pipelines of different diameters by adjusting the position of the grinding part 107, reducing the complexity of manual adjustment, reducing the difficulty of operation, and significantly improving the detection efficiency.

[0045] Drive mechanism 2 40, which is located in the middle of the detection mechanism 10, is used to adjust the distance between the detector 108 and the gas pipeline, so that the detector 108 can detect the hardness of steam pipelines of different diameters. By adjusting the position of the detector 108, drive mechanism 2 40 improves the accuracy and stability of hardness detection and reduces the influence of human factors on the measurement results.

[0046] The connecting mechanism 50, located outside the drive mechanism 40, provides a spring-loaded space for the grinding piece 107, allowing it to retract upon contact with a protruding part of the gas pipeline, thus avoiding forced operation. The connecting mechanism 50 includes a connecting component for quick replacement of the grinding piece 107, enabling rapid adjustment to the required grinding fineness for the gas pipeline. The connecting mechanism 50 allows the grinding piece 107 to adaptively adjust when encountering uneven or protruding pipe surfaces, preventing damage to the pipe surface due to forced contact. This extends the service life of the grinding piece 107, reduces downtime, and improves testing efficiency and safety. Furthermore, it allows operators to quickly replace the grinding piece 107 as needed to adjust the grinding fineness and meet different testing requirements.

[0047] Please see the appendix Figure 1 - Appendix Figure 3 In a preferred embodiment of the present invention, the detection mechanism 10 includes a support plate 101. Wheels 102 are fixedly connected to the bottom of the support plate 101, enabling the entire device to move easily to the detection position, thereby reducing the workload of the operator. A handrail 103 is fixedly connected to the outer side of the support plate 101, controlling the movement of the device and ensuring its operability in complex environments, making the operation of the device more user-friendly. A sliding connection is made to the upper side of the support plate 101. Two brackets 104 are provided. An arc-shaped plate 105 is fixedly connected to the upper side of the bracket 104. A limiting plate 109 rotates in the middle of the arc-shaped plate 105. An arc-shaped plate 106 is fixedly connected to the other side of the limiting plate 109. The limiting plate 109 is used to connect the arc-shaped plate 105 and the arc-shaped plate 106 to prevent parallel detachment. At the same time, under the action of the brackets 104, the two arc-shaped plates 105 and the two arc-shaped plates 106 can be connected respectively to wrap the gas pipeline for subsequent inspection operations.

[0048] Please see the appendix Figure 2In a preferred embodiment of the present invention, the adjusting mechanism 20 includes a cylinder 201, which is fixedly connected inside the support plate 101. A housing 202 is fixedly connected to the output end of the cylinder 201. A dual-head motor 203 is fixedly connected inside the housing 202. Lead screws 204 are fixedly connected to both output ends of the dual-head motor 203. The two lead screws 204 are designed in opposite directions. A nut seat 205 is threaded onto the outer circumference of each lead screw 204. A bracket 104 is fixedly connected to the upper side of the nut seat 205. By driving cylinder 201, the box 202 can move the bracket 104 up and down, thereby moving the arc plate 105 and the arc plate 106 to the same height as the gas pipeline, so that gas pipelines at different heights can be detected. At the same time, by driving the double-head motor 203, the two lead screws 204 are rotated, thereby causing the nut seat 205 to move the two brackets 104 closer or further apart, so that the two arc plates 105 and the two arc plates 106 can move stably and wrap around the gas pipeline.

[0049] Please see the appendix Figure 4 - Appendix Figure 6In a preferred embodiment of the present invention, the drive mechanism 30 includes a motor 301, which is fixedly connected to the outside of one of the arc-shaped plates 105. A gear 302 is fixedly connected to the output end of the motor 301. A gear ring 303 is fixedly connected to the outside of the arc-shaped plate 106. Both gear rings 303 mesh with the gear 302. By driving the motor 301 and under the action of the gear rings 303, the gear 302 can drive the arc-shaped plate 106 to rotate. At this time, the grinding part 107 can rotate around the gas pipeline. A T-shaped rod 304 is slidably connected to the middle of the arc-shaped plate 106. One end of the T-shaped rod 304 is fixedly connected to... The device has a protrusion 305, a ring 306 fixedly connected to the outer periphery of a T-shaped rod 304, and a ring 306 fixedly connected inside an arc-shaped plate 106. The T-shaped rod 304 passes through the ring 306 fixed inside the arc-shaped plate 106. Multiple springs 307 are arranged between the two rings 306. A sprocket 308 is rotatably connected inside the arc-shaped plate 106. A locking assembly is arranged between the sprocket 308 and the arc-shaped plate 106. A groove 309 is opened at one end of the sprocket 308. The T-shaped rod 304 and the protrusion 305 are slidably connected in the middle of the groove 309. By pressing the T-shaped rod 304, the ring 306 compresses the springs 307. Simultaneously, the locking assembly closes, and the protrusion 305 enters the sprocket 308. Rotating the T-shaped rod 304 then rotates the sprocket 308. When the T-shaped rod 304 is released, the spring 307 separates the protrusion 305 from the sprocket 308, activating the locking assembly. Two sprockets 310 are rotatably connected inside the arc-shaped plate 106. A chain 311 meshes with the outer periphery of the two sprockets 310 and sprocket 308. A turntable 312 is fixedly connected to one end of each sprocket 310, rotatably connected inside the arc-shaped plate 106. An eccentric rod 313 is fixedly connected to the other end of the turntable 312. A connecting belt 314 is sleeved on the outer periphery of the rod 313. The connecting belt 314 is slidably connected to the inside of the arc plate 106. A top plate 315 is fixedly connected to the outer side of the connecting belt 314. The grinding part 107 is set on the side of the top plate 315 away from the connecting belt 314. When the sprocket 308 rotates, the chain 311 can drive the sprocket 310 and the turntable 312 to rotate. At this time, the connecting belt 314 drives the grinding part 107 to approach the gas pipeline through the eccentric rod 313, so that it contacts the gas pipeline. When the arc plate 106 rotates, the grinding part 107 rotates, so that the outer periphery of the gas pipeline can be ground quickly and conveniently.

[0050] Please see the appendix Figure 3 and attached Figure 7In a preferred embodiment of the present invention, the second drive mechanism 40 includes two sets of covers 401, which are respectively fixedly connected to the outside of two arc-shaped plates 105. A second cylinder 402 is fixedly connected inside the cover 401. The cover 401 can effectively prevent the external environment from interfering with the second cylinder 402, such as collision, thereby extending the service life of the second cylinder 402. A connecting rod 403 is fixedly connected to the output end of the second cylinder 402. One set of detectors 108 is fixedly connected to the end of the connecting rod 403 away from the second cylinder 402. By driving the second cylinder 402, the connecting rod 403 can drive the detectors 108 to move. The two sets of detectors 108 are respectively used to perform metallographic inspection and hardness testing on the gas pipeline.

[0051] Please see the appendix Figure 4 In a preferred embodiment of the present invention, the connecting mechanism 50 includes a connecting plate 501, which is fixedly connected to the top plate 315 on the side away from the connecting belt 314. A second compression spring 502 is fixedly connected to the other side of the connecting plate 501, and a fixing block 503 is fixedly connected to the other end of the second compression spring 502. A limiting rod 504 is fixedly connected to the side of the fixing block 503 near the connecting plate 501. The limiting rod 504 is slidably connected to the middle of the connecting plate 501. When the grinding part 107 grinds the gas pipeline, if it encounters a protruding part, the grinding part 107 is squeezed, thereby causing the fixing block 503 to compress the second compression spring 502. When there is no pressure, the grinding part 107 pops out, thereby avoiding hard contact between the grinding part 107 and the protruding part of the gas pipeline, increasing the service life of the grinding part 107. Under the action of the limiting rod 504, the fixing block 503 can be prevented from shifting when moving, thereby improving the grinding accuracy of the grinding part 107.

A locking block 507 is fixedly connected to the other side of the T-shaped plate 506. A positioning block 508 is fixedly connected to the side of the grinding component 107 near the top plate 315. The positioning block 508 and the fixing block 503 are interlocked. A slot 509 is formed in the middle of the positioning block 508. The locking block 507 and the slot 509 are interlocked. By inserting the positioning block 508 into the fixing block 503... In step 3, the clamping block 507 is squeezed upon entry, causing the T-shaped plate 506 to compress the compression spring 505. When the slot 509 moves to a position parallel to the clamping block 507, the compression spring 505 can spring the clamping block 507 into the slot 509, thus quickly installing the grinding part 107. By pressing the T-shaped plate 506, the clamping block 507 and the slot 509 can be quickly separated, thereby improving the installation and removal speed of the grinding part 107. This design not only improves the ease of operation and adaptability of the device, but also effectively improves the detection accuracy and efficiency, ensuring high efficiency, safety and reliability in the metallographic inspection and hardness testing process.

[0053] Please see the appendix Figure 2 In a preferred embodiment of the present invention, two grooves 70 are provided on the upper side of the support plate 101, and the nut seat 205 is slidably connected to the middle of the groove 70. The groove 70 can limit the nut seat 205, thereby preventing the bracket 104 from shifting when moving, so that the arc plate one 105 and the arc plate two 106 can only move in parallel, thereby completing the subsequent precision grinding work.

[0054] Please see the appendix Figure 8 In a preferred embodiment of the present invention, a positioning groove is provided on the side of the fixing block 503 near the grinding part 107, and the positioning block 508 is slidably connected to the middle of the positioning groove. The positioning groove limits the positioning block 508, thereby enabling the grinding part 107 and the fixing block 503 to be quickly aligned, thus improving the installation speed of the grinding part 107.

[0055] Please see the appendix Figure 8 In a preferred embodiment of the present invention, the side of the card block 507 near the positioning block 508 is set to be arc-shaped so that it can move when squeezed, thereby reducing wear and speeding up the connection. The arc shape optimizes the installation and use process of the grinding part 107, thereby improving the ease of operation and detection efficiency of the device, while reducing the maintenance frequency and cost.
