Description

Technical Field

[0001] The invention relates to the technical field of oil pipeline cleaning, in particular to a pipe wall cleaning machine for oil production oil delivery pipelines. Background Art

[0002] The pipe wall cleaning machine for oil extraction oil pipeline is a device used to clean dirt and impurities on the inner wall of the pipeline. Its main function is to ensure the smooth flow of the pipeline, improve the efficiency of oil transportation, and reduce the occurrence of pipeline blockage and failure. The working principle of the cleaning machine is usually to remove dirt through physical, chemical or mechanical methods. The use of the cleaning machine can effectively maintain the normal operation of the oil extraction oil pipeline.

[0003] Chemical cleaning or high-pressure water jet cleaning is usually used in the market to clean the inner wall of the oil pipeline. On the one hand, chemical cleaning uses specific chemical agents to dissolve or react with dirt, and chemical agents are corrosive to pipelines, which affects the service life of the pipeline after the cleaning is completed. Secondly, improper handling of chemical agents will cause environmental pollution. At the same time, chemical agents will not be ideal for some special dirt, resulting in poor cleaning effect. On the other hand, high-pressure water jet cleaning uses high-pressure water flow to impact the inner wall of the pipeline to remove dirt. First, the energy consumption of high-pressure water flow impacting the inner wall of the pipeline is relatively high. Secondly, the distance of high-pressure water flow impacting the pipeline is limited, and it is impossible to clean the stains deep inside the oil pipeline. In addition, the market also uses pipe cleaners to clean the oil pipeline, and the pipe cleaners on the market have poor cleaning effects on some stains with particularly strong adhesion and special texture. Secondly, the cleaning method of the pipe cleaner is relatively single, and the pipe cleaner is not accurate enough when dealing with some local stubborn small-area stains.

[0004] The pipe wall cleaning machines for oil pipelines on the market are usually equipped with multiple power units, which makes the overall structure of the equipment more complicated, increases the probability of failure and the difficulty of maintenance. Secondly, multiple power units require more installation space, which will impose certain restrictions on the pipeline layout and the surrounding environment. In addition, the simultaneous operation of multiple power units will consume more energy. At the same time, the coordinated control between multiple power units is more difficult, which will lead to problems such as uneven operation or asynchrony, affecting the cleaning effect. In addition, multiple power units increase the overall weight of the equipment, which is not conducive to transportation and installation operations.

[0005] The pipe wall cleaning machines for oil pipelines on the market use rollers to contact the inner wall of the pipe to move the equipment. However, the contact area between the roller and the inner wall of the pipe is small, and some oil will remain on the inner wall of the pipe, causing the pulley to slip, which in turn causes the cleaning equipment to be stuck or unable to pass smoothly.

[0006] Therefore, it is necessary to provide a pipe wall cleaning machine for oil production oil delivery pipeline to solve the above problems. Summary of the invention

[0012] Preferably, the scraping assembly includes a sealing disk, the sealing disk is fixedly connected to the end of the cylindrical block away from the collecting disk, the inside of the sealing disk is fixedly connected to a positioning column, the end of the positioning column away from the sealing disk is rotatably connected to a hollow rotating bar, the side of the hollow rotating bar away from the positioning column is rotatably connected to a hexagonal rotating rod, the side of the hexagonal rotating rod close to the hollow rotating bar is fixedly connected to six positioning pins in a ring-shaped distribution, and the outer walls of the six positioning pins are rotatably connected to pulleys.

[0013] Preferably, the scraping assembly also includes a lever bar, which is slidably connected to the inside of the hollow rotating bar, and the inside of the lever bar is rotatably connected to an L-shaped rotating rod, the side of the hexagonal rotating rod away from the hollow rotating bar is fixedly connected to a fixed rod, and the end of the fixed rod away from the hexagonal rotating rod is fixedly connected to a hollow scraper wheel.

[0017] Preferably, the L-shaped rotating rod is fixedly connected to an end of the second rotating rod away from the second rotating block, the lever strip is Y-shaped, and a threaded scraping strip is provided on the outer wall of the hollow scraper wheel.

[0018] The invention provides a pipe wall cleaning machine for oil production oil pipeline. Compared with the prior art, the invention has the following beneficial effects: 1. Through the arrangement of the moving assembly, when the arc-shaped gear plate drives the rack rod, the rack rod drives the I-shaped groove plate to move horizontally. Because the second return spring causes the limit slide plate to contact the inner wall of the oil pipeline through the I-shaped groove plate, the reverse force generated by the limit slide plate during the rotation of the arc-shaped gear plate drives the cylindrical block to move as a whole, so that the cylindrical block can drive the collecting plate to scrape the stains on the inner wall of the oil pipeline when it moves, so that the machine can automatically move and work in the pipeline without too much manual intervention, saving manpower and operation time. At the same time, the machine can crawl and scrape the stains at the same time, ensuring that all parts of the inner wall of the pipeline are effectively cleaned, and the collecting plate can synchronously drive the stains to move, avoiding the stains from remaining or accumulating, thereby improving the cleaning efficiency and quality.

[0019] Secondly, compared with the chemical cleaning methods on the market, it avoids the corrosion of chemical agents to the pipeline, and at the same time avoids the environmental pollution caused by chemical agents and the unsatisfactory effect of treating dirt. At the same time, compared with the high-pressure water flow impact method, it solves the problem that the high-pressure water flow impact on the pipeline is limited. The distance caused by the problem cannot clean the stains deep inside the oil pipeline.

[0020] 2. Through the arrangement of the scraping assembly, during the rotation of the driving device, the driving device can drive the L-shaped rotating rod to rotate through the power conversion assembly, so that when the L-shaped rotating rod drives the lever bar to slide along the inside of the hollow rotating bar, the lever bar can continuously drive the hexagonal rotating rod to rotate through the pulley, so that the hexagonal rotating rod drives the hollow scraper wheel to rotate intermittently through the fixed rod, thereby achieving the purpose of continuously scraping the stains on the inner wall of the oil pipeline through the hollow scraper wheel, thereby facilitating the subsequent collection of the stains inside the oil pipeline. At the same time, the intermittent rotation can continuously act on the stains to ensure effective scraping, which is helpful to achieve uniform scraping of the inner wall of the oil pipeline, avoiding excessive or insufficient local scraping of the inner wall of the oil pipeline, thereby facilitating the smooth transportation of oil and ensuring the stability of the transportation process.

[0021] Secondly, compared with the pipe cleaners on the market, the hollow scraper can loosen and scrape stains on the inner wall of the oil more effectively, because the intermittent rotation can make the scraping tool stay at a specific position and concentrate on scraping. For some stubborn stains or local severely polluted areas, it can give more sufficient action time and strength to achieve precise cleaning, so that the intermittent rotation of the hollow scraper can scrape the stains on the inner wall of the oil pipe more targeted, and the hollow scraper can operate more concentratedly on specific areas.

[0022] 3. Through the setting of the power conversion component, it is achieved that during the rotation of the first connecting rod, the Z-shaped rotating block can be rotated by the first rotating block, and the Z-shaped rotating block drives the second rotating rod to rotate through the second rotating block, so that when the driving device drives the arc-shaped gear plate to rotate, the driving device synchronously and indirectly drives the second rotating rod to rotate, so that only one power device is set up for the whole equipment, thereby reducing the number of power devices, thereby reducing the overall cost of the equipment and subsequent maintenance costs, and at the same time making the equipment structure relatively simple, reducing the probability of failure, and facilitating daily inspection and maintenance, and not requiring too much space to accommodate multiple power devices, and having relatively low requirements for the installation environment, only one power device needs to be precisely controlled, so that the complexity of the control system is reduced, and it is easier to achieve stable and precise operation, which is beneficial to the transportation, installation and operation of the equipment and improves convenience.

[0023] 4. Through the setting of the conductive plate, when the reverse force generated by moving the limit slide plate during the rotation of the arc-shaped gear disk drives the cylindrical block to move as a whole, the cylindrical block will drive the conductive plate to move. When the conductive plate moves to the inside of the power-on hole, the conductive plate energizes the electromagnet group through the power-on hole, and the electromagnet group can magnetically attract the limit slide plate, thereby contacting the limit slide plate against the oil pipeline, so that the arc-shaped gear disk can continuously move the rack rod to drive the cylindrical block to move horizontally. Compared with the traditional method of using a roller as the contact surface to drive the overall movement, the contact surface between the rack rod and the inner wall of the oil pipeline is larger, which facilitates the overall movement of the cleaning device. At the same time, the setting of the conductive plate achieves the purpose of magnetically attracting the limit slide plate through the electromagnet group, thereby achieving the purpose of continuously resetting the limit slide plate, thereby making the cleaning device move more smoothly.

[0043] The moving component includes a cylindrical block 21, which is arranged inside the oil delivery pipe 11.

The outer wall of the I-shaped groove plate 29 is provided with a power-on hole 211.

[0045] The electromagnet group 210 is electrically connected to the power-on hole 211 through an electric wire, so that the conductive plate 212 can energize the electromagnet group 210 through the power-on hole 211. The conductive plate 212 and the drive device 23 are both electrically connected to the power supply used by the equipment, so that the conductive plate 212 and the drive device 23 can be energized synchronously with the power supply used by the equipment. The limit slide plate 214 is set to be made of metal steel near the electromagnet group 210, and is used to magnetically attract the limit slide plate 214 after the electromagnet group 210 is energized.

[0046] The power conversion assembly includes a working groove 31, which is opened inside the cylindrical block 21. The bottom of the working groove 31 is rotatably connected to the first connecting rod 32, and the top of the first connecting rod 32 is rotatably connected to the first rotating block 33. The end of the first rotating block 33 away from the first connecting rod 32 is rotatably connected to the Z-shaped rotating block 34, and the end of the Z-shaped rotating block 34 away from the first rotating block 33 is rotatably connected to the second rotating block 35. The end of the second rotating block 35 away from the Z-shaped rotating block 34 is rotatably connected to the second rotating rod 36, and the second rotating rod 36 is rotatably connected to the top of the working groove 31.

[0047] The first connecting rod 32 is fixedly connected to the top of the output shaft of the driving device 23, so that the first connecting rod 32 can be driven to rotate when the driving device 23 is started.

[0048] The scraping assembly includes a sealing disk 41, which is fixedly connected to one end of the cylindrical block 21 away from the collecting disk 215. A positioning column 42 is fixedly connected inside the sealing disk 41. An end of the positioning column 42 away from the sealing disk 41 is rotatably connected to a hollow rotating bar 43. The side of the hollow rotating bar 43 away from the positioning column 42 is rotatably connected to a hexagonal rotating rod 44. Six positioning pins 45 are fixedly connected in a ring-shaped manner on one side of the hexagonal rotating rod 44 close to the hollow rotating bar 43. The outer walls of the six positioning pins 45 are rotatably connected to pulleys 46.

[0049] The scraping assembly also includes a lever bar 47, which is slidably connected to the inside of the hollow rotating bar 43. The inside of the lever bar 47 is rotatably connected to an L-shaped rotating rod 48. The side of the hexagonal rotating rod 44 away from the hollow rotating bar 43 is fixedly connected to a fixed rod 49, and the end of the fixed rod 49 away from the hexagonal rotating rod 44 is fixedly connected to a hollow scraper wheel 410.

[0050] The arc gear plate 24 is rotatably connected to the inside of the rotating groove 22 , the rotating groove 22 is connected to the square slide groove 25 , the arc gear plate 24 is meshed with the rack rod 26 , and the rack rod 26 and the square connecting block 27 are both slidably connected to the inside of the square slide groove 25 .

[0051] The L-shaped rotating rod 48 is fixedly connected to one end of the second rotating rod 36 away from the second rotating block 35, so that the second rotating rod 36 can drive the L-shaped rotating rod 48 to rotate, the lever bar 47 is Y-shaped, and the L-shaped rotating rod 48 is rotatably connected to the inside of the lever bar 47, so that the lever bar 47 can be driven to move during the rotation of the L-shaped rotating rod 48. The outer wall of the hollow scraper 410 is provided with a threaded scraper strip, so that the threaded scraper strip of the hollow scraper 410 can better scrape off the stains on the inner wall of the oil transmission pipe 11.

[0052] When the driving device 23 drives the arc-shaped gear plate 24 to rotate, it will synchronously drive the first connecting rod 32 to rotate, and the first connecting rod 32 will rotate by driving one end of the Z-shaped rotating block 34 through the first rotating block 33, and the other end of the Z-shaped rotating block 34 will rotate by driving the second rotating rod 36 through the second rotating block 35, and then the second rotating rod 36 drives the L-shaped rotating rod 48 fixedly connected thereto to rotate, thereby achieving the purpose of power conversion.

[0053] Working principle: In the initial state, the cylindrical block 21 is located at the end of the rack rod 26 away from the sealing disk 41, the first return spring 28 and the second return spring 213 are not compressed, the conductive plate 212 does not conflict with the power-on hole 211, the electromagnet group 210 does not magnetically attract the limit slide 214, the top of the lever bar 47 conflicts with the pulley 46, and the limit slide 214 conflicts with the inner wall of the oil delivery pipe 11.

[0054] During operation, the staff first needs to put the hollow scraper 410 into the oil delivery pipe 11, and then start the equipment to use power after the cylindrical block 21 and the collecting plate 215 are completely put into the oil delivery pipe 11.

[0055] Because the conductive plate 212 and the driving device 23 are both electrically connected to the power supply used by the equipment, the conductive plate 212 and the driving device 23 are powered on synchronously with the power supply used by the equipment. After the driving device 23 is powered on, its output shaft gradually drives the arc-shaped gear plate 24 to rotate along the inside of the rotating groove 22. Because the arc-shaped gear plate 24 is meshed with the rack rod 26, and the rotating groove 22 is connected to the square slide groove 25, the arc-shaped gear plate 24 then gradually drives the rack rod 26 to slide along the inside of the square slide groove 25 away from the sealing disk 41, and the rack rod 26 will synchronously drive the square connecting block 27 fixedly connected thereto to compress the first return spring 28 in the direction away from the sealing disk 41.

[0056] Therefore, the limiting slide plate 214 is in conflict with the inner wall of the oil delivery pipe 11. Therefore, when the arc-shaped gear plate 24 moves the rack rod 26, the rack rod 26 is fixedly connected to the limiting slide plate 214 that is in conflict with the inner wall of the oil delivery pipe 11 through the I-shaped groove plate 29, and then the arc-shaped gear plate 24 causes the cylindrical block 21 to generate a force opposite to the movement of the rack rod 26. Therefore, the cylindrical block 21 drives the collecting plate 215 to slide along the inner wall of the oil delivery pipe 11 toward the rack rod 26. In the process of the collecting plate 215 moving along the inner wall of the oil delivery pipe 11, the stains on the inner wall of the oil delivery pipe 11 will be gradually scraped off, thereby achieving a cleaning effect.

[0057] After the driving device 23 is energized, it will continue to drive the arc-shaped gear plate 24 to rotate along the inside of the rotating groove 22, so that the arc-shaped gear plate 24 and the rack rod 26 are out of contact. At this time, the cylindrical block 21 drives the conductive plate 212 to gradually move to the inside of the power-on hole 211. Then, because the electromagnet group 210 and the power-on hole 211 are electrically connected through wires, and because the above-mentioned conductive plate 212 and the driving device 23 are energized synchronously with the power supply of the equipment, the conductive plate 212 energizes the electromagnet group 210 through the power-on hole 211. After the electromagnet group 210 is energized, it gradually magnetically attracts the limiting slide plate 214, and then the limiting slide plate 214 gradually moves toward the direction of the I-shaped groove plate 29. At the same time, the limiting slide plate 214 gradually compresses the second return spring 213 toward the direction of the I-shaped groove plate 29.

[0058] When the limiting slide plate 214 contacts the I-shaped groove plate 29, the limiting slide plate 214 cannot contact the inner wall of the oil delivery pipe 11, and then the compressed first return spring 28 in the above-mentioned motion state gradually elastically stretches to push the square connecting block 27 and the rack rod 26 to slide and return along the inside of the square slide groove 25 toward the sealing disk 41, and the rack rod 26 drives the limiting slide plate 214 to move through the I-shaped groove plate 29, and then the limiting slide plate 214 gradually moves to the end of the square slide groove 25 close to the sealing disk 41, so that the conductive plate 212 is separated from the power-on hole 211 at this time. The second return spring 213 elastically extends and pushes the limiting slide 214 to move away from the I-shaped groove plate 29. Finally, the end of the limiting slide 214 away from the I-shaped groove plate 29 again conflicts with the inner wall of the oil delivery pipe 11, thereby achieving the purpose of continuously moving the cylindrical block 21. Compared with the traditional method of using a roller as the contact surface to drive the overall movement, the contact surface between the limiting slide 214 and the inner wall of the oil delivery pipe 11 is larger, which facilitates the overall movement of the cleaning device and makes the cleaning device move more smoothly.

[0059] After the driving device 23 is powered on, it will continue to drive the arc-shaped gear plate 24 to rotate along the inside of the rotating groove 22, and then repeat the above movement process. The collecting plate 215 will continue to move along the inner wall of the oil delivery pipe 11 and scrape off the stains on the inner wall of the oil delivery pipe 11.

[0060] Because the first connecting rod 32 is fixedly connected to the top of the output shaft of the driving device 23, the driving device 23 will drive the first connecting rod 32 to rotate during the process of driving the arc-shaped gear plate 24 to rotate, and the first connecting rod 32 will rotate by driving one end of the Z-shaped rotating block 34 through the first rotating block 33, and the other end of the Z-shaped rotating block 34 will rotate by driving the second rotating rod 36 through the second rotating block 35, and then the second rotating rod 36 will drive the L-shaped rotating rod 48 fixedly connected thereto to rotate, thereby achieving the purpose of power conversion.

[0061] When the second rotating rod 36 drives the L-shaped rotating rod 48 to rotate, because the lever bar 47 is Y-shaped and the L-shaped rotating rod 48 is rotatably connected to the inside of the lever bar 47, the L-shaped rotating rod 48 will first drive the lever bar 47 to slide toward the inside of the hollow rotating bar 43, and at the same time, the L-shaped rotating rod 48 will drive the lever bar 47 to rotate away from one end of the hollow rotating bar 43, and then the lever bar 47 will drive the positioning pin 45 to rotate through the pulley 46, and the positioning pin 45 will drive the hexagonal rotating rod 44 to rotate.

[0062] Then, the L-shaped rotating rod 48 continues to rotate, and the lever bar 47 slides in the direction of the pulley 46 on the outer wall of the next positioning nail 45. Then, during the sliding process of the lever bar 47, the positioning nail 45 will continue to be rotated through the pulley 46, and the positioning nail 45 will drive the hexagonal rotating rod 44 fixedly connected to it to rotate. Finally, the hexagonal rotating rod 44 will drive the fixed rod 49 on the side away from the positioning nail 45 to rotate intermittently, and the fixed rod 49 will drive the hollow scraper 410 fixedly connected to it to rotate. Because the outer wall of the hollow scraper 410 is provided with a threaded scraping strip, the hollow scraper 410 will scrape the stains on the inner wall of the oil delivery pipe 11 during its rotation. Because the hollow scraper 410 rotates intermittently during its rotation, the scraping tool can be moved in a special Staying at a fixed position and concentrating on scraping can provide more sufficient action time and strength for some stubborn stains or severely polluted areas, thereby achieving the purpose of precise cleaning. The spiral shape of the hollow scraper 410 can generate a forward propulsion force, helping the hollow scraper 410 to move more smoothly in the oil pipe and improve cleaning efficiency. Compared with traditional scraping tools, the spiral structure can better contact with the inner wall of the oil pipe and can scrape stains more deeply, especially for some firmly attached dirt, the cleaning effect is better. Secondly, during the rotation process, the spiral scraper has a certain "transporting" effect, which can better push the scraped stains forward and reduce local accumulation, thereby achieving a certain self-cleaning effect, while other tools are prone to dirt accumulation.

[0063] Subsequently, due to the movement of the cylindrical block 21 , the dirt scraped off from the inside of the oil delivery pipe 11 passes through the gap of the hollow scraper wheel 410 and is finally collected by the collecting plate 215 .
