Description

Technical Field

[0001] This utility model relates to the field of gas pipeline cleaning technology, and in particular to an auxiliary device for cleaning gas pipelines. Background Technology

[0002] Natural gas extraction pipelines refer to pipelines mainly used for transporting natural gas. Due to the limitations of some extraction areas, after a long period of extraction, solids such as sand and rust will accumulate inside the extraction pipeline. The accumulation of solids such as sand and rust can cause blockages in the extraction pipeline, affecting the gas transmission operation.

[0003] For example, patent application number CN202022159062.0 discloses a pipe cleaning machine, including a drive motor and a reducer. The drive motor and the reducer are connected by a flexible shaft. The front end of the reducer is provided with a drill shaft and a drill bit. The drill bit rotates circumferentially along the pipe. Output shafts are provided on both sides of the reducer. Drive wheels are provided on the output shafts on both sides of the reducer. The drive wheels drive the reducer to move axially along the pipe. The reducer is provided with an input gear set, a first reduction gear set, and a second reduction gear set. The input end of the input gear set is connected to the flexible shaft. The output end of the input gear set is connected to the input end of the first reduction gear set and the input end of the second reduction gear set, respectively. The output end of the first reduction gear set is connected to the drill shaft. The output end of the second reduction gear set is connected to the output shafts on both sides of the reducer. The reduction ratio of the first reduction gear set is smaller than that of the second reduction gear set. These types of pipe cleaning machines use a trolley to move inside the pipes and clear the blockage. As a result, they are relatively large and may not be able to enter pipes of different diameters, affecting their applicability. Utility Model Content

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] according to Figure 1 , 2 As shown in Figure 3, this embodiment proposes a gas pipeline cleaning auxiliary device, including an installation cylinder 1 and a guide pipe 14. The upper end of the guide pipe 14 is provided with an adjusting screw 9, which is rotatably connected to the guide pipe 14. The installation cylinder 1 is sleeved on the outside of the adjusting screw 9, and the adjusting screw 9 is threadedly connected to the installation cylinder 1.

[0024] Multiple support wheel frames are provided on the outside of the mounting cylinder 1. The support wheel frames cooperate with the positioning post 12 sleeved on the outside of the guide tube 14. The positioning post 12 is fixedly connected to the guide tube 14 and is used to drive each support wheel frame to open and close when the guide tube 14 moves.

[0025] The lower end of the guide pipe 14 is equipped with a spray assembly, and the outside of the support wheel frame is equipped with a brush plate structure, which is detachably connected to the support wheel frame. This detachable connection facilitates cleaning and replacement of the brush plate structure.

[0026] As the cleaning auxiliary device moves inside the pipeline, the spray assembly at the end of the guide pipe 14 flushes the inner wall of the pipeline. Rotating the adjusting screw 9 pushes the guide pipe 14, causing the guide pipe 14 to move along with the positioning column 12. During movement, the positioning column 12 cooperates with the support wheel frame, allowing each support wheel frame to open or retract simultaneously. After being extended, the support wheel frame supports the guide pipe 14 from the inside of the pipeline, ensuring that the guide pipe 14 remains centered in the pipeline and does not shift when the cleaning auxiliary device moves inside pipelines of different sizes, providing good stability. In addition, by rotating the mounting cylinder 1, the brush plate structure on the outside of the support wheel frame can also clean the inner wall of the pipeline, making it convenient and practical.

[0027] Regarding the support wheel frame:

[0028] The support frame includes diagonal braces 2 and movable arms 3. The diagonal braces 2 are fixedly mounted on the outside of the mounting cylinder 1. The diagonal braces 2 are evenly distributed circumferentially along the axis of the mounting cylinder 1. The end of the diagonal brace 2 away from the mounting cylinder 1 is hinged to the movable arm 3. The end of the movable arm 3 away from the diagonal brace 2 is provided with a guide wheel 4, which is rotatably connected to the movable arm 3. The movable arm 3 is rotatably connected to the diagonal brace 2 via a pivot. When the positioning column 12 moves, all the movable arms 3 will extend and retract synchronously.

[0029] Specifically, a sector gear 5 is provided at the end of the movable arm 3 away from the guide wheel 4. The sector gear 5 is fixedly connected to the movable arm 3 and meshes with the teeth 13 located on the outside of the positioning post 12. Each movable arm 3 is connected to a sector gear 5. When the adjusting screw 9 pushes or pulls the guide tube 14, the guide tube 14 will drive the positioning post 12 to move accordingly. During the movement, the positioning post 12 meshes with each sector gear 5, thereby causing each movable arm 3 to rotate, completing the synchronous adjustment of each movable arm 3.

[0030] To ensure that the positioning post 12 and the guide tube 14 remain horizontal and do not deflect during movement, the mounting cylinder 1 is provided with multiple limiting rods 16 on the side near the positioning post 12. The limiting rods 16 are fixedly connected to the mounting cylinder 1, and the other end of each limiting rod 16 passes through the positioning post 12, with the limiting rod 16 slidably connected to the positioning post 12. A baffle 17 is provided at the end of the limiting rod 16 away from the mounting cylinder 1. The baffle 17 is fixed to the end of the limiting rod 16, serving to limit the positioning post 12. When the positioning post 12 is pushed or pulled, it moves along the body of the limiting rod 16, and the limiting rod 16, in cooperation with the positioning post 12, limits the positioning post 12 and the guide tube 14.

[0031] Regarding the brush plate structure:

[0032] The brush plate structure includes a rod 6 and a brush plate 7. One end of the rod 6 is fixedly connected to the brush plate 7, and the other end of the rod 6 passes through the movable arm 3 and is slidably connected to the movable arm 3. A fixing bolt 8 is fitted on the outside of the movable arm 3, and the fixing bolt 8 passes through the movable arm 3 and is threadedly connected to the mounting hole on the outside of the rod 6. When replacing the brush plate 7, simply rotate the fixing bolt 8 to unscrew it from the mounting hole on the outside of the rod 6. The removal of dirt mainly relies on high-pressure water rinsing, with the brush plate structure serving as an auxiliary cleaning function.

[0033] It is worth explaining in detail that the spray assembly includes a guide hose 15 and a nozzle 18. The guide hose 15 is fixedly installed at the upper end of the guide pipe 14, and the nozzle 18 is fixedly installed at the lower end of the guide pipe 14. The guide hose 15 is connected to the nozzle 18 through the guide pipe 14. The guide hose 15 is connected to a water pump. When cleaning the pipeline, the valve on the guide hose 15 will open, and high-pressure water will enter the guide pipe 14 through the guide hose 15, and then be sprayed out from the nozzle 18 through the guide pipe 14 to flush the inner wall of the pipeline.

[0034] To facilitate the user's rotation of the adjusting screw 9, in a preferred embodiment, a handle 10 is provided at the end of the adjusting screw 9 away from the guide tube 14, and the handle 10 is fixedly connected to the adjusting screw 9. Rotating the adjusting screw 9 is achieved by simply turning the handle 10.

[0035] To facilitate the movement of the mounting cylinder 1, in a preferred embodiment, a mounting plate 11 is provided at the end of the mounting cylinder 1 furthest from the positioning post 12. The mounting plate 11 is fixedly connected to the mounting cylinder 1, and several bolt holes are provided at the end of the mounting plate 11 furthest from the mounting cylinder 1. The mounting plate 11 is connected to an external flexible hose by bolting. The mounting cylinder 1 is pushed forward and backward within the pipe by the external flexible hose. The bolting connection facilitates the assembly and disassembly of the mounting cylinder 1.

[0036] How this application works:

[0037] As the cleaning auxiliary device moves inside the pipeline, the spray assembly at the end of the guide pipe 14 flushes the inner wall of the pipeline. Rotating the adjusting screw 9 pushes the guide pipe 14, causing the guide pipe 14 to move along with the positioning column 12. During movement, the positioning column 12 cooperates with the support wheel frame, allowing each support wheel frame to open or retract simultaneously. After being extended, the support wheel frame supports the guide pipe 14 from the inside of the pipeline, ensuring that the guide pipe 14 remains centered in the pipeline and does not shift when the cleaning auxiliary device moves inside pipelines of different sizes, ensuring good stability. In addition, by rotating the mounting cylinder 1, the brush plate structure on the outside of the support wheel frame can also clean the inner wall of the pipeline. The removal of dirt mainly relies on high-pressure water flushing, with the brush plate structure serving as an auxiliary cleaning function.
