Description

Technical Field

[0001] This utility model relates to the field of pipeline interface protection technology, specifically a high-pressure pipeline interface protection device. Background Technology

[0002] In industrial manufacturing, various high-pressure pipeline protection devices are frequently used, especially at the interface between the branch high-pressure pipeline and the main pipeline.

[0003] According to a protective structure for an internally corrosion-resistant pipe joint with application number 202223405781.1, a base is included, and a sleeve rod for fixing is installed on the top of the base. A threaded rod for support is internally threaded to the sleeve rod. An adjusting disc for adjusting the height is fixedly provided on the outer edge of the threaded rod. A support mechanism for support is threaded to the threaded rod. A protection mechanism for protecting the pipe joint is fixedly connected above the support mechanism. The protection mechanism includes a lower fixed seat and an upper fixed seat. A shock-absorbing mechanism is installed inside the protection mechanism.

[0004] However, the above-mentioned pipe interface protection structure has certain shortcomings. Although the structure can reduce the vibration of the pipe by setting a shock-absorbing mechanism, its overall protection performance and anti-detachment performance are poor, and it cannot effectively prevent the connection pipe from falling off the interface of the high-pressure pipe. Therefore, we propose a high-pressure pipe interface protection device. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figures 1 to 6 This utility model provides a technical solution: a high-pressure pipeline interface protection device, including a high-pressure pipeline 1, an interface 2 at the top of the high-pressure pipeline 1, a connecting pipeline 3 connected to one end of the interface 2, two main sleeves 4 installed on the outside of the high-pressure pipeline 1, a protective sleeve 5 at the top of the main sleeves 4, a limiting groove 6 inside the protective sleeve 5, the interface 2 cooperating with the limiting groove 6, several first fixing ears 7 fixedly installed on the outside of both the main sleeves 4 and the protective sleeve 5, a first fixing bolt 8 inside the first fixing ear 7, and a hole inside the first fixing ear 7 that mates with the first fixing bolt 8, and a pull sleeve 9 installed on the outside of the connecting pipeline 3. An anti-slip washer 10 is provided on the inner side of the sleeve 9. The anti-slip washer 10 is made of rubber. An anti-detachment washer 11 is provided on the inner side of the sleeve 9 and above the anti-slip washer 10. The inside of the sleeve 9 is provided with grooves that mate with the anti-slip washer 10 and the anti-detachment washer 11. Several anti-detachment teeth 12 are provided on the inner side of the anti-detachment washer 11. The anti-slip washer 10, the anti-detachment washer 11 and the anti-detachment teeth 12 all mate with the connecting pipe 3. A second fixing ear 13 is fixedly installed on both sides of the sleeve 9. A second fixing bolt 14 is provided inside the second fixing ear 13. Two adapter ears 21 are fixedly installed on one side of the sleeve 9. A pull rod 20 is rotatably installed on the inner side of the adapter ear 21.

[0024] Both the main sleeve 4 and the protective sleeve 5 are equipped with buffer pads inside to cushion the vibrations caused by the flow of the medium in the high-pressure pipeline 1 and the connecting pipeline 3. The two main sleeves 4 and the protective sleeve 5 are connected and fixed by the first fixing lug 7 and the first fixing bolt 8. The anti-slip washer 10 is made of rubber and uses the friction generated by its contact with the surface of the connecting pipeline 3 to tighten and fix it. The anti-disengagement teeth 12 can firmly grip the surface of the connecting pipeline 3, and in the event of a loose connection between the connecting pipeline 3 and the interface 2, they can firmly hold the connecting pipeline 3 in place, preventing it from shifting and being dislodged.

[0025] A tensioning sleeve 15 is fixedly installed on one side of the main sleeve 4. A groove 16 is opened inside the tensioning sleeve 15. A threaded rod 17 is rotatably installed inside the groove 16. A slider 18 is threadedly installed on the outside of the threaded rod 17. A hole that mates with the threaded rod 17 is opened inside the slider 18. The slider 18 is slidably connected to the inner wall of the groove 16. Limiting shafts 19 are fixedly installed on both sides of the slider 18. One end of the pull rod 20 is rotatably connected to the limiting shaft 19. A knob 22 is fixedly installed on the outside of the bottom of the tensioning sleeve 15 at one end of the threaded rod 17.

[0026] In summary, when using this high-pressure pipeline interface protection device, after the connecting pipeline 3 is connected to the interface 2, the two main sleeves 4 are positioned with the interface 2 through the limiting groove 6 on the inner side of the protective sleeve 5. Then, the main sleeves 4 and the protective sleeve 5 are installed and fixed on the outside of the high-pressure pipeline 1 and the connecting pipeline 3 by the first fixing bolt 8 and the first fixing ear 7. Then, the pull rod 20 is rotated to make the two pull sleeves 9 fit on the outside of the connecting pipeline 3. Then, the two pull sleeves 9 are fixed on the outside of the connecting pipeline 3 by the second fixing bolt 14 and the second fixing ear 13. Finally, the knob 22 is rotated to drive the threaded rod 17 to rotate. The threaded rod 17 drives the slider 18 to move down through the thread. At the same time, the pull rod 20 is pulled down through the limiting rotating shaft 19. Thus, the pull rod 20 applies a downward pulling force to the pull sleeves 9, so that the pull sleeves 9 are fixed on the outside of the connecting pipeline 3, and the installation is completed.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
