Description

Technical Field

[0001] This utility model relates to the field of pipeline maintenance technology, and in particular to a pipe plugging device for carbon steel pipelines used in chemical cleaning. Background Technology

[0002] Carbon steel pipes, also known as carbon steel tubes, are steel pipes with carbon as the main alloying element. They are usually made by piercing steel ingots or solid tube blanks to form rough tubes, and then processing them through hot rolling, cold rolling or cold drawing. The main purpose of chemical cleaning of carbon steel pipes is to remove foreign matter such as grease, rust, and oxide layer from the inner wall of the pipe to ensure the cleanliness of the inner wall of the pipe. This helps to improve the flow capacity and heat transfer efficiency of the pipe, and also helps the subsequent anti-corrosion layer to adhere and the long service life of the pipe.

[0003] When chemically cleaning carbon steel pipelines, pipe plugging devices are required to prevent the cleaning solution from flowing out. Existing pipe plugging devices typically seal the pipeline by inserting a plugging plate inside the pipe. However, the support effect of the plugging plate is poor, and it cannot be supported on both the inside and outside of the pipeline at the same time. As a result, the impact force generated during chemical cleaning can cause the plugging plate to shift and fall off, leading to the leakage of cleaning solution and affecting the chemical cleaning effect of the pipeline. In addition, the sealing area of ​​the pipe plugging device is relatively fixed, which cannot seal pipelines of different sizes, affecting the efficiency of chemical cleaning of carbon steel pipelines.

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0025] Example 1:

[0026] Reference Figures 1-4 This is the first embodiment of the present invention. This embodiment provides a pipe plugging device for carbon steel pipes used in chemical cleaning, including a pipe body 1, a shell 2 disposed inside the pipe body 1, a plugging plate 3 installed on the top of the shell 2 to plug the pipe body 1, a sealing gasket 4 disposed on the outside of the plugging plate 3 to improve the sealing performance of the pipe body 1, a push block 5 slidably connected to the inner wall of the shell 2 to limit the position of the plugging plate 3, a transmission component 6 disposed on the outside of the push block 5, a gear plate 7 disposed on the outside of the shell 2, and a limiting component 8 disposed on the top of the gear plate 7 to prevent the plugging plate 3 from falling off.

[0027] The sealing plate 3 seals the inside of the pipe body 1, facilitating subsequent chemical cleaning of the carbon steel pipe. The sealing gasket 4 improves the sealing performance of the sealing plate 3 on the pipe body 1. The push block 5 contacts the inner wall of the pipe body 1, improving the stability of the sealing plate 3 and preventing the sealing plate 3 from falling off due to the impact of the water flow generated by the cleaning fluid. The transmission component 6 drives the push block 5 to move, so that multiple sets of push blocks 5 support the inner wall of the pipe body 1. The limiting component 8 achieves the effect of installing this device on the pipe body 1, avoiding the problem of large water flow impact affecting the sealing effect. The inner wall of the toothed disc 7 is rotatably connected to the outer side of the housing 2, and it is convenient to install the toothed disc 7 on the outer side of the housing 2.

[0028] The transmission assembly 6 includes a slider 61 fixed to one side of the push block 5, a transmission block 62 slidably connected to the outer side of the slider 61, a slide rod 63 fixedly connected to the inner wall of the transmission block 62 to limit the slider 61, and an anti-slip pad 64 provided on one side of the push block 5.

[0029] The outer side of the slide rod 63 is slidably connected to the inner wall of the slider 61. The anti-slip pad 64 improves the stability of the push block 5 in contact with the inner wall of the tube body 1. The outer side of the transmission block 62 has an inclined angle. By moving the transmission block 62 up and down, the slider 61 slides on the outer side of the slide rod 63, pushing the push block 5 to slide inside the housing 2, so that the push block 5 contacts the inner wall of the tube body 1 to support the sealing plate 3.

[0030] The limiting component 8 includes a guide groove 81 disposed in the inner cavity of the gear plate 7, a guide rod 82 slidably connected to the inner wall of the guide groove 81, a mounting bracket 83 fixedly connected to the top of the guide rod 82, and a limiting bracket 84 for limiting the tube body 1 installed on one side of the mounting bracket 83.

[0031] Mounting bracket 83 is installed on limiting bracket 84 by bolts. Guide groove 81 has a certain curvature. By rotating the gear plate 7, guide rod 82 is pulled to slide inside guide groove 81. Guide rod 82 moves continuously towards the center of gear plate 7, thereby driving limiting bracket 84 to clamp the outside of pipe body 1, avoiding the problem of large water flow impact affecting the sealing effect.

[0032] Example 2:

[0033] This is the second embodiment of the present invention, which is based on the previous embodiment.

[0034] Specifically, a mounting base 9 is fixedly connected to the top of the housing 2, and a mounting bolt 10 for installing the sealing plate 3 is threadedly connected to the inner wall of the mounting base 9.

[0035] The sealing plate 3 is installed on the outside of the mounting base 9 by mounting bolt 10, and it is convenient to replace the sealing plate 3 of different sizes, so as to seal carbon steel pipes of different sizes.

[0036] Specifically, the bottom of the housing 2 is fixedly connected to multiple sets of fixing plates 11, and the bottom of the fixing plates 11 is fixedly connected to a support plate 12.

[0037] The shell 2 is supported by the fixing plate 11 and the support plate 12, thereby improving the stability of the shell 2.

[0038] Specifically, a first motor 13 is installed on the outer side of the fixing plate 11, a first bevel gear 14 is fixed to the output end of the first motor 13, a second bevel gear 15 is meshed with the outer side of the first bevel gear 14, and a threaded rod 16 that drives the transmission block 62 to move is fixedly connected to the inner ring of the second bevel gear 15.

[0039] The bottom of the threaded rod 16 is rotatably connected to the top of the support plate 12, and the outer side of the threaded rod 16 is threadedly connected to the inner wall of the transmission block 62. The first motor 13 drives the first bevel gear 14 and the second bevel gear 15 to rotate, which in turn drives the threaded rod 16 to rotate, causing the transmission block 62 to move up and down.

[0040] Example 3:

[0041] This is the third embodiment of the present invention, which is based on the first two embodiments.

[0042] Specifically, a support plate 17 is provided at the bottom of the support plate 12, and a second motor 18 is installed at the top of the support plate 17. The output end of the second motor 18 is fixedly connected to a drive gear 19 that drives the gear plate 7 to rotate.

[0043] The outer side of the drive gear 19 meshes with the outer side of the gear disk 7.

[0044] Specifically, a support block 20 is fixed to the top of the support plate 17, and a limit rod 21 is fixedly connected to the outside of the support block 20.

[0045] The housing 2 is installed on top of the support block 20, and it is convenient to remove the housing 2 later.

[0046] Specifically, a limiting sleeve 22 for limiting the guide rod 82 is slidably connected to the outer side of the limiting rod 21, and a limiting block 23 for limiting the limiting sleeve 22 is fixedly connected to one end of the limiting rod 21.

[0047] The guide rod 82 is fixed to the top of the limiting sleeve 22. The movement of the guide rod 82 causes the limiting sleeve 22 to slide outside the limiting rod 21, so that the guide rod 82 moves horizontally.

[0048] In use, the sealing plate 3 is installed on the outside of the mounting base 9 using the mounting bolts 10, which facilitates the replacement of sealing plates 3 of different sizes and allows for the sealing of carbon steel pipes of different dimensions. The housing 2 and the sealing plate 3 are inserted into the pipe body 1, and the sealing plate 3 seals the inside of the pipe body 1, facilitating subsequent chemical cleaning of the carbon steel pipe. The sealing gasket 4 improves the sealing performance of the sealing plate 3 on the pipe body 1. The first motor 13 drives the first bevel gear 14 and the second bevel gear 15 to rotate, which in turn drives the threaded rod 16 to rotate, causing the transmission block 62 to move up and down. The outer side of the transmission block 62 has an inclined angle. The up and down movement of the transmission block 62 causes the slider 61 to slide outside the slide rod 63, pushing the push block 5 to slide inside the housing 2. The push block 5 contacts the inner wall of the pipe body 1 to support the sealing plate 3 and prevent the water flow generated by the cleaning fluid from impacting it. To address the issue of the sealing plate 3 falling off, the anti-slip pad 64 improves the stability of the push block 5 contacting the inner wall of the pipe body 1. The second motor 18 drives the drive gear 19 and the gear disc 7 to rotate. The rotation of the gear disc 7 pulls the guide rod 82 to slide inside the guide groove 81. The guide rod 82 continuously moves towards the center of the gear disc 7. The movement of the guide rod 82 causes the limiting sleeve 22 to slide outside the limiting rod 21, allowing the guide rod 82 to move horizontally. This, in turn, causes the limiting frame 84 to clamp the outside of the pipe body 1, improving the stability of the sealing of the pipe body 1 and avoiding the problem of large water flow impact affecting the sealing effect. It can be used to seal pipe bodies 1 of different sizes. The shell 2 and the gear disc 7 can be used independently. For pipe bodies 1 with a small cleaning water flow, the shell 2 and the push block 5 can be used for sealing. For pipe bodies 1 with a large size, the large impact force generated can be reinforced by the gear disc 7 and the limiting frame 84.

[0049] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
