Description

Technical Field

[0001] This utility model relates to the technical field of pipe manhole structure, and in particular to a pipe manhole installation structure. Background Technology

[0002] Pipelines require maintenance during routine use. Existing technology typically involves prefabricating inspection well openings on the pipeline during production, then installing branch pipes, and manually entering the wells or manually inspecting the pipeline. The installation of branch pipes for maintenance is cumbersome, generally achieved through welding, which is inefficient and difficult to operate, making it hard to achieve rapid and stable installation of maintenance branch pipes. Furthermore, it is difficult to install on pipelines that are not suitable for welding. In response to the above shortcomings, this application is proposed. Utility Model Content

[0003] The purpose of this utility model is to provide a pipe manhole installation structure that enables a quick and stable connection between the branch pipe and the main pipe, thereby improving the efficiency of later installation and maintenance of branch pipes in the pipeline.

[0004] To address the aforementioned problems, this utility model provides a pipe manhole installation structure, including a branch pipe, a sealing ring, a pressure ring, and a main fixing assembly. The pressure ring is fitted onto the outer circumference of the branch pipe to compress the sealing ring. At least two main fixing assemblies are provided, each including a screw connector, a locking screw, a lifting rod, a support claw, and a top block. The top block is installed on the inner wall of the branch pipe. The screw connector is connected to the lifting rod, and the locking screw is installed on the screw connector. The pressure ring is located below the locking screw and is used to adjust the lifting rod's movement and to compress the pressure ring. The support claw is rotatably connected to the lifting rod, allowing it to have an extended and retracted state. After the lifting rod raises the support claw, it contacts the top block and rotates from the retracted state to the extended state. When the support claw is in the extended state, it contacts the inner wall of the pipe.

[0005] The top block is located at the lower part of the inner wall of the branch pipe, on the lifting path of the support claw. When the support claw is retracted, it is easy for the branch pipe to be inserted into the opening on the pipe. When the locking screw is tightened, the support claw rises and one side of its rotating mounting point contacts the top block, thereby causing the support claw to rotate and switch to the extended state, contacting the inner wall of the pipe. At the same time, the locking screw can also press down on the pressure ring, so that the pressure ring presses against the sealing ring to achieve a sealing and fixing effect.

[0006] According to one embodiment of the present invention, at least two sets of auxiliary fixing components are installed on the branch pipe. The auxiliary fixing components are arranged crosswise with the main fixing components. The auxiliary fixing components include an auxiliary fixing plate, a rotation adjustment body, and a limiting screw. The auxiliary fixing plate is connected to the rotation adjustment body, and the limiting screw is connected to the rotation adjustment body. The length of the auxiliary fixing plate is greater than the length of the support claw.

[0007] According to one embodiment of the present invention, the auxiliary fixing plate and the support claw are at different heights.

[0008] During the insertion of the branch pipe into the pipeline, the rotating adjustment body is rotated to position the auxiliary fixing plate inside the circumference of the branch pipe, avoiding interference during insertion. After insertion, the rotating adjustment body is rotated to expand the auxiliary fixing plate to the outside of the branch pipe, abutting against the inner wall of the pipeline. Since the length of the auxiliary fixing plate is greater than the length of the support claw, and the auxiliary fixing plate is set lower than the height of the support claw, a support is formed on the periphery of the support claw, increasing the number of support points, improving the stability of the branch pipe installation, and avoiding excessive local stress at the pipe opening.

[0009] According to one embodiment of the present invention, the lifting rod extends through the inside of the branch pipe.

[0010] According to one embodiment of the present invention, the rotation adjustment body extends through the interior of the branch pipe.

[0011] According to one embodiment of the present invention, the pressure ring is provided with a groove for accommodating the end of the locking screw.

[0012] According to one embodiment of the present invention, the pressure ring is provided with a groove for accommodating the end of the limiting screw.

[0013] The groove diameter is larger than the screw diameter, which helps to prevent misalignment.

[0014] According to one embodiment of this utility model, the locking screw and the limiting screw have different head sizes, preferably different models, to facilitate differentiation. During installation, all limiting screws are tightened first, and then the locking screw is tightened.

[0015] According to one embodiment of the present invention, the sealing ring is a rubber sealing ring, and the number of such sealing rings can be set to several groups.

[0016] The beneficial effects of this utility model are that, by setting the main fixing component, when installing the branch pipe, which serves as the maintenance inlet, onto the pipeline, it is only necessary to insert the branch pipe into the opening on the pipeline, and use the locking screw to make the support claw contact the inner wall of the pipeline. The locking screw presses down on the pressure ring, causing the pressure ring to press the sealing ring, thereby achieving a sealing and fixing effect. The fixing method is quick and effective, and easy to install. Moreover, the support claw is rotatable and has a retractable state, so there is no interference when installing the branch pipe, which further facilitates installation and improves installation efficiency.

[0022] The following description is only intended to disclose the present invention so that those skilled in the art can implement it. The embodiments in the following description are merely examples, and those skilled in the art will conceive of other obvious modifications. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other solutions that do not depart from the spirit and scope of the present invention.

[0023] Example 1:

[0024] A pipe manhole installation structure, such as Figure 1 It includes a branch pipe 1, a sealing ring 10, a pressure ring 4, and a main fixing assembly. This assembly is used to enable the quick installation of inspection ports on pipelines and is suitable for pipelines with general or moderate sealing requirements.

[0025] The sealing ring 10 is made of rubber and can be set in several groups. During installation, the pressure ring 4 is first put on, and then the sealing ring 10 is put on.

[0026] like Figure 2 As shown, before installation, an opening is made in the pipe 11 where the branch pipe needs to be installed, usually using a drilling rig.

[0027] The pressure ring 4 is fitted onto the outer circumference of the branch pipe 1 to compress the sealing ring 10.

[0028] At least two sets of main fixing components and at least two sets of auxiliary fixing components are set, and the auxiliary fixing components are distributed alternately with the main fixing components.

[0029] like Figure 2 The main fixing component includes a screw connector 7, a locking screw 5, a lifting rod 6, a support claw 9, and a top block 12. The lifting rod 6 passes through a through hole in the body of the branch pipe 1, and several sealing rings are provided on the lifting rod 6 along its axial direction to form an interference seal with the through hole. The lifting rod 6 can move up and down.

[0030] like Figure 4 The top block 12 is installed on the inner wall of the branch pipe 1 to limit the position of the support claw 9.

[0031] The screw connector 7 is connected to the lifting rod 6. The locking screw 5 is installed on the screw connector 7. The pressure ring 4 is located on the lower side of the locking screw 5. The locking screw 5 is used to adjust the lifting of the lifting rod 6 and to press the pressure ring 4.

[0032] The support claw 9 and the lifting rod 6 are rotatably connected by a pin, so that the support claw 9 has an extended state and a retracted state. After the lifting rod 6 drives the support claw 9 to rise, the support claw 9 contacts the top block 12 and rotates to switch from the retracted state to the extended state. When the support claw 9 is in the extended state, it is used to contact the inner wall of the pipe.

[0033] The top block 12 is located at the lower part of the inner wall of the branch pipe 1, and is on the lifting path of the support claw 9. When the support claw 9 is retracted, it is easy for the branch pipe 1 to be inserted into the opening on the pipe. During the tightening of the locking screw 5, the support claw 9 rises and one side of its rotating mounting point contacts the top block 12, thereby causing the support claw 9 to rotate and switch to the unfolded state, contacting the inner wall of the pipe. At the same time, the locking screw 5 can also press down the pressure ring 4, so that the pressure ring 4 presses the sealing ring 10 to achieve a sealing and fixing effect.

[0034] Usage process:

[0035] Drill a hole in pipe 11, adjust the support claw 9 to the retracted state, insert the branch pipe 1 into the opening of the pipe, tighten the locking screw 5, so that the support claw 9 rotates and switches to the extended state, contacting the inner wall of the pipe. At the same time, the locking screw 5 can also press down the pressure ring 4, so that the pressure ring 4 presses the sealing ring 10, achieving a sealing and fixing effect.

[0036] The modular design of the manhole installation structure facilitates the replacement of damaged components.

[0037] Example 2:

[0038] Based on Example 1, this example adds an auxiliary fixing component, such as... Figure 2 , Figure 3 The auxiliary fixing component includes an auxiliary fixing plate 8, a rotation adjustment body 3, and a limiting screw 2. The rotation adjustment body 3 includes a rod part located in a through hole inside the branch pipe 1. Similar to the lifting rod 6, it also uses multiple sealing rings to achieve sealing.

[0039] The lower end of the rotating adjustment body 3 is connected to the auxiliary fixing plate 8, and the upper end has a bent part. The limiting screw 2 is connected to the bent part of the rotating adjustment body 3. The length of the auxiliary fixing plate 8 is greater than the length of the support claw 9, and the auxiliary fixing plate 8 and the support claw 9 are at different heights.

[0040] During the process of branch pipe 1 entering the pipeline, the rotating adjustment body 3 is rotated to make the auxiliary fixing plate 8 located inside the circumference of branch pipe 1 to avoid interference during insertion. After entering, the rotating adjustment body 3 is rotated to make the auxiliary fixing plate 8 unfold to the outside of branch pipe 1 and abut against the inner wall of the pipeline. At this time, the limiting screw 2 is installed and the pressure ring is tightened.

[0041] Because the length of the auxiliary fixing plate 8 is greater than the length of the support claw 9, and the auxiliary fixing plate 8 is set lower than the height of the support claw 9, a support is formed on the periphery of the support claw 9, increasing the number of support points, forming multi-point support, improving the stability of the branch pipe installation, and avoiding excessive local stress at the pipe opening.

[0042] Preferably, the pressure ring 4 is provided with a groove for accommodating the ends of the locking screw 5 and the limiting screw 2. The diameter of the groove is larger than the diameter of the screw, which plays a certain role in preventing misalignment.

[0043] Preferably, the locking screw 5 and the limiting screw 2 have different head sizes, and more preferably, the two screws are of different models, so as to facilitate differentiation. During installation, all the limiting screws 2 are tightened first, and then the locking screw 5 is tightened.

[0044] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functional and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations and modifications.
