[0038] This application provides a sealing ring removal device. For example... Figure 1 and 4 As shown, in some embodiments, the sealing ring removal device includes:

[0039] Support structure 10;

[0040] Lifting assembly 20 includes:

[0041] The lifting boom 201 is movably connected to the support structure 10; and

[0042] The fixing mechanism 202 is connected to the lifting rod 201. The fixing mechanism 202 is used to fix the sealing ring 40. When the lifting rod 201 rises, it drives the fixing mechanism 202 and the sealing ring 40 to rise.

[0043] In this embodiment, the support structure 10 can be made of a rigid material, primarily providing stable support; for example, the support structure 10 can be made of rigid metal sheets such as steel plates or aluminum alloy plates. The support structure 10 can be a support frame, which is made of rigid metal materials such as steel plates or aluminum alloy plates. The lifting rod 201 can be made of a rigid material and is used to drive the fixing mechanism 202 to rise and fall; for example, the lifting rod 201 can be made of rigid metal materials such as steel or aluminum alloy. The fixing mechanism 202 can be made of a rigid material; for example, the fixing mechanism 202 can be made of rigid metal sheets such as steel plates or aluminum alloy plates.

[0044] The support structure 10 has a through hole, the shape of which is adapted to the shape of the lifting rod 201. In some embodiments, the support structure 10 has a circular hole with internal threads, and the lifting rod 201 has external threads. The inner diameter of the circular hole is greater than or equal to the outer diameter of the lifting rod 201. The lifting rod 201 and the support structure 10 can be screwed into the circular hole through the threads, which can make the lifting movement of the lifting rod 201 more stable.

[0045] The fixing mechanism 202 is fixedly connected to the lower end of the lifting rod 201; for example, the fixing mechanism 202 can be connected to the lower end of the lifting rod 201 by welding or integral molding. In other embodiments, the fixing mechanism 202 is movably connected to the lower end of the lifting rod 201; for example, the fixing mechanism 202 can be connected to the lower end of the lifting rod 201 by screwing, which facilitates the disassembly and replacement of the fixing mechanism 202.

[0046] In this embodiment, the lifting rod 201 can be driven by a motor or a rotating nut, etc., to perform lifting and lowering movements. For example, when the driving mechanism is a rotating nut, the lifting rod 201 is screwed to the rotating nut. The rotation of the rotating nut can drive the lifting rod 201 to perform lifting and lowering movements. When the lifting rod 201 rises, it drives the fixing mechanism 202 to rise. The front end of the fixing mechanism 202 can abut against the inner side of the sealing ring 40, playing a role in opening and fixing the sealing ring 40 during the process of pulling the sealing ring 40 up. When the fixing mechanism rises, it drives the sealing ring 40 to rise, thereby stably pulling the sealing ring 40 upward.

[0047] The sealing ring removal device provided in this application embodiment can reliably fix the deformed sealing ring 40 by means of the fixing mechanism 202, and can stably lift the deformed sealing ring 40 upward by means of the lifting rod 201 and the fixing mechanism 202, and complete the removal. During the removal of the sealing ring 40, there is no need to strike or pry, which can effectively avoid the problem of damage to the pipe clutch; moreover, the device effectively solves the problems of difficulty in removing the pipe clutch sealing ring 40 after it is deformed by pressure and the low replacement efficiency of the sealing ring 40.

[0048] like Figure 1 As shown, in some embodiments, the support structure 10 includes a first support frame 101, a second support frame 102, and a third support frame 103. The second support frame 102 and the third support frame 103 are respectively connected to both ends of the first support frame 101, and the lifting rod 201 is movably connected to the first support frame 101. The first support frame 101, the second support frame 102, and the third support frame 103 mainly provide stable lifting and support for the lifting rod 201 and the fixing mechanism 202. In the embodiments of this application, the first support frame 101, the second support frame 102, and the third support frame 103 are made of rigid metal plates such as steel plates or aluminum alloy plates. The second support frame 102 and the third support frame 103 are respectively fixedly connected to both ends of the first support frame 101 by welding. The first support frame 101, the second support frame 102, and the third support frame 103 can be rectangular thin plates. Through the stable lifting and supporting action of the first support frame 101, the second support frame 102 and the third support frame 103, the lifting rod 201 and the fixing mechanism 202 can move up and down stably. When the fixing mechanism 202 rises, it can stably pull up the sealing ring 40.

[0049] In this embodiment, a through hole is provided at the middle position of the first support frame 101. The shape of the through hole is adapted to the shape of the lifting rod 201, allowing the lifting rod 201 to pass through the through hole and move up and down. In other embodiments, the first support frame 101 has a circular hole with an internal thread, and the lifting rod 201 has an external thread. The inner diameter of the circular hole is greater than or equal to the outer diameter of the lifting rod 201. When the inner diameter of the circular hole is threadedly connected to the outer diameter of the lifting rod 201, the lifting rod 201 can move up and down stably within the circular hole.

[0050] In other embodiments, the second support frame 102 and the third support frame 103 are detachably connected to both ends of the first support frame 101, and the lifting rod 201 is movably connected to the middle of the first support frame 101. For example, the top ends of the second support frame 102 and the third support frame 103 can be detachably connected to both ends of the first support frame 101 by means of screwing or snap-fit ​​connection. The first support frame 101 is provided with a circular hole with an internal thread, and the lifting rod 201 is provided with an external thread. The lifting rod 201 is screwed to the first support frame 101 by the thread, which can provide stable support for the lifting rod 201.

[0051] like Figure 1 and 2 As shown, in some embodiments, the sealing ring removal device further includes a first nut 30, which is disposed on the support structure 10. The lifting rod 201 is a screw rod, and the screw rod and the first nut 30 are screwed together. In this embodiment, the first nut 30 can abut against the upper surface of the support structure 10. The first nut 30 can abut against the upper surface of the first support frame 101. The first nut 30 has an internal thread, and the screw rod has an external thread. The screw rod is screwed to the first nut 30 through the thread. By rotating the first nut 30, the screw rod can be driven to move up and down, thereby driving the fixing mechanism 202 to move up and down. When the screw rod rises, it can drive the fixing mechanism 202 to rise and stably pull up the sealing ring 40, completing the removal of the sealing ring 40.

[0052] like Figure 1 and 2As shown, in some embodiments, the fixing mechanism 202 includes a base 2021, a plurality of bolts 2022, and a plurality of second nuts 2023. The base 2021 is connected to the lifting rod 201, the plurality of second nuts 2023 are fixed to the base 2021, and the plurality of bolts 2022 and the plurality of second nuts 2023 are screwed together in a one-to-one correspondence. The front ends of the plurality of bolts 2022 are used to abut against the inner side of the sealing ring 40 respectively. In this embodiment, the plurality of bolts 2022 are provided with external threads, and the plurality of second nuts 2023 are provided with internal threads. The plurality of second nuts 2023 are screwed together with the plurality of bolts 2022 in a one-to-one correspondence through threads. When rotated, the front ends of the second nuts 2023 extend toward the sealing ring 40 and abut against the inner side of the sealing ring 40. During the process of pulling up the sealing ring 40, it can open and fix the sealing ring 40, and can make the front end of the second nut 2023 tightly fixed on the inner side of the sealing ring 40. When the second nut 2023 is lifted upward, the sealing ring 40 can be pulled up stably upward.

[0053] In this embodiment, the base 2021 is made of a rigid metal plate such as steel plate or aluminum alloy plate. The specific shape of the base 2021 is not limited, as long as it provides stable support for components such as the bolt 2022; for example, the base 2021 can be disc-shaped or toothed. The base 2021 can be fixedly connected to the lower end of the screw rod. For example, the base 2021 can be connected to the lower end of the screw rod by welding or integral molding. Multiple second nuts 2023 can be connected to the base 2021 by welding or other methods; specifically, the multiple second nuts 2023 can be welded to the edge of the base 2021. In other embodiments, the base 2021 is detachably connected to the lower end of the screw rod. For example, the base 2021 can be detachably connected to the lower end of the screw rod by screwing or snap-fit ​​connection, which facilitates the disassembly and replacement of the base 2021.

[0054] In other embodiments, multiple bolts 2022 are arranged at an angle to the base 2021, forming a certain angle that allows the bolts 2022 to rotate smoothly. This allows the front ends of the bolts 2022 to extend towards the sealing ring 40 and abut against the inner surface of the sealing ring 40, thus opening and reliably fixing the sealing ring 40. Simultaneously, the angled arrangement of the bolts 2022 with the base 2021 also facilitates tightening the bolts 2022. Furthermore, the bolts 2022 are arranged at a 45-degree angle to the base 2021, which further facilitates the front ends of the bolts 2022 abutting against the inner surface of the sealing ring 40, thus opening and reliably fixing the sealing ring 40. For example, the central axis of each bolt 2022 can form a 45-degree angle with the central axis of the base 2021.

[0055] like Figure 1-4As shown, in some embodiments, a plurality of second nuts 2023 are fixed to the base 2021, and the plurality of second nuts 2023 are set at an angle to the base 2021. A plurality of bolts 2022 and a plurality of second nuts 2023 are screwed together in a one-to-one correspondence, thereby making the bolts 2022 set at an angle to the base 2021, which is beneficial for the front part of the bolts 2022 to extend toward the sealing ring 40 and abut against the inner side of the sealing ring 40.

[0056] It should be noted that in this embodiment, the number of bolts 2022 is not limited, as long as the number of bolts 2022 is sufficient to reliably fix the sealing ring 40; correspondingly, the number of second nuts 2023 is also not limited, as long as they correspond one-to-one with the number of bolts 2022.

[0057] like Figure 1 and 2 As shown, in some embodiments, the fixing mechanism 202 further includes a third nut 2024, which is fixedly connected to the base 2021; for example, the third nut 2024 is connected to the base 2021 by welding or integral molding. The lower end of the screw is connected to the third nut 2024. The third nut 2024 has an internal thread, and the lower end of the screw of the third nut 2024 is screwed in, which facilitates the disassembly of the third nut 2024.

[0058] like Figure 1-4 As shown, in some embodiments, there are three bolts 2022, which are respectively set at an angle to the base 2021. There are also three second nuts 2023, which are screwed onto the three bolts 2022 respectively. When rotating, the front ends of the three bolts 2022 extend toward the sealing ring 40 and abut against the inner side of the sealing ring 40, which can open and fix the sealing ring 40, thereby preventing the sealing ring 40 from falling off during the upward pulling process.

[0059] In other embodiments, the three bolts 2022 are set at a 45-degree angle to the base 2021, which is more conducive to the front end of the bolts 2022 extending toward the sealing ring 40 and abutting against the inner side of the sealing ring, thereby securely fixing the sealing ring 40.

[0060] like Figure 1-4 As shown, in some embodiments, the bolt 2022 has a spike 20221 at its front end, which is used to penetrate the upper inner surface of the sealing ring 40. When rotated, the spike 20221 extends toward the sealing ring 40 and penetrates the upper inner surface of the sealing ring 40, which can further securely fix the sealing ring 40, allowing the sealing ring 40 to be steadily pulled upward. The spike 20221 may be tapered.

[0061] like Figure 3 and 4As shown, in some embodiments, the base 2021 is a disc, and the second nut 2023 is fixed to the edge of the disc. For example, the second nut 2023 can be fixed to the edge of the disc by welding or other methods. By fixing the second nut 2023 to the edge of the disc, the bolt 2022 screwed onto the second nut 2023 can be set at a certain angle to the disc, which facilitates the smooth rotation of the bolt 2022 and its extension toward the sealing ring 40. In other embodiments, three second nuts 2023 are evenly fixed to the edge of the disc, so that three bolts 2022 are evenly arranged on the base 2021, which can stably pull the sealing ring 40 upward.

[0062] In other embodiments, the base 2021 is a triangular plate, and three second nuts 2023 are respectively fixed to the three apex edges of the triangular plate. By designing the base 2021 as a triangular plate, the load can be reduced to a certain extent while ensuring sufficient strength, and the driving force for pulling the sealing ring 40 upward can be saved to a certain extent.

[0063] like Figure 4 As shown, when removing the sealing ring 40 using the sealing ring removal device provided in this application embodiment, the removal device is first placed above the sealing ring 40. The first nut 30 is rotated to lower the screw and drive the bolt 2022 to fall below the upper edge of the upper inner side of the sealing ring 40. Then, the three bolts 2022 are rotated respectively to extend the spikes 20221 at the front end of the three bolts 2022 towards the upper inner side of the sealing ring 40 and penetrate into the inner side of the sealing ring 40. The three bolts 2022 are rotated respectively to securely fix the upper part of the sealing ring 40 with the three spikes 20221. Finally, the first nut 30 is rotated in the opposite direction to move the screw upward and simultaneously pull the sealing ring 40 upward, thus completing the removal of the sealing ring 40.

[0064] The sealing ring removal device provided in this application embodiment not only ensures that the sealing ring of the pipe clutch remains stable in position during the upward pulling process, thus allowing the sealing ring to be pulled out stably, but also effectively avoids damage to the pipe clutch caused by using traditional tools to replace the sealing ring.

[0065] Compared with traditional removal tools, this device can quickly remove and replace the sealing rings, significantly reduce manpower input, and greatly improve the efficiency of sealing ring replacement.

[0066] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. All embodiments obtained by any modifications, alterations or equivalent substitutions made by those skilled in the art without departing from the technical concept of this application shall fall within the scope of protection of the claims of this application.
