Description

Technical Field

[0001] This utility model relates to the field of petrochemical pipeline cleaning technology, specifically a petrochemical pipeline cleaning mechanism. Background Technology

[0002] In the petrochemical industry, pipelines are important facilities for transporting various media. However, due to the characteristics of the media and the influence of the pipeline operating environment, impurities, dirt, wax, scale and other substances are easily accumulated on the inner wall of the pipeline. These deposits not only reduce the effective flow area of ​​the pipeline and increase the resistance to transporting the media, leading to increased energy consumption, but may also cause problems such as pipeline blockage and accelerated corrosion, seriously affecting the safe operation and service life of the pipeline, and may even cause safety accidents.

[0003] A gas pipeline cleaning and construction mechanism, as described in reference announcement number CN220635661U, includes a cylinder with a cleaning mechanism inside and a sewage discharge assembly outside. The cleaning mechanism includes a first motor fixedly connected to the cylinder, with a lead screw fixedly connected to the output end of the first motor inside the cylinder. A threaded cylinder slidably connected to the cylinder is threaded to the external end of the lead screw. A second motor is fixedly connected inside the threaded cylinder, with a rotating shaft fixedly connected to the output end of the second motor. This gas pipeline cleaning and construction mechanism, by incorporating the cleaning mechanism, adds a dust extraction function, sucking up impurities and dust from inside the gas pipeline, reducing the residue of impurities and dust inside the gas pipeline. This solves the problem of existing gas pipeline cleaning structures, which primarily focus on cleaning but lack dust extraction capabilities, easily leaving residual impurities inside the gas pipeline, affecting the cleaning effect and efficiency. As can be seen from the above, while this cleaning mechanism can be well applied, it is usually inconvenient to adjust the overall height of the cleaning mechanism, making it difficult to perform cleaning operations on petrochemical pipelines in designated height areas, often causing problems. Utility Model Content

[0004] The purpose of this utility model is to provide a petrochemical pipeline cleaning mechanism to solve the problem mentioned in the background art that although the cleaning mechanism can be well applied, it is usually not convenient to adjust the overall height of the cleaning mechanism, thus making it difficult to carry out cleaning operations on petrochemical pipelines in a specified height area.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a petrochemical pipeline cleaning mechanism, comprising a movable base, a strip seat at the top of the movable base, a limiting rail at the top of the strip seat, two limiting blocks slidably connected to one side of the top of the limiting rail, a bearing seat installed at the top of the limiting blocks, a lower frame fixedly installed on one side of the top of the bearing seat, an upper frame movably installed at the upper end of the lower frame, the top of the upper frame extending to the outside of the lower frame and having a vertical frame, two guide rails on the inner wall of the vertical frame, two rail seats slidably connected to the outer wall of the guide rails, movable frames installed on the outer walls of several rail seats, a lifting cylinder installed at the bottom of the vertical frame, the top of the lifting cylinder connected to the inner wall of the movable frame, a motor installed on one side of the upper outer wall of the movable frame, one end of the motor penetrating the movable frame and having a roller brush installed thereon.

[0006] Preferably, a lower connecting seat is installed at the top of the bearing seat inside the lower frame body, and an upper connecting seat is installed at the bottom of the upper frame body. The upper and lower connecting seats are used to accommodate the V-shaped lifting arm.

[0007] Preferably, V-shaped lifting arms are rotatably installed on both sides of the bottom end of the upper connecting seat, and the bottom end of the V-shaped lifting arm is rotatably connected to the top end of the lower connecting seat. The V-shaped lifting arms are used to adjust the distance between the upper and lower connecting seats.

[0008] Preferably, a nut seat is rotatably installed at the center of the surface of the V-shaped lifting arm, and a double-acting screw is installed on the internal threads of the two nut seats. A handle is installed at one end of the double-acting screw, and the double-acting screw is driven to rotate by rotating the handle.

[0009] Preferably, a connecting seat is installed at the bottom of the bearing seat, and a positioning frame is installed at the top of the movable base on one side of the strip seat. The positioning frame is used to position the electric push rod.

[0010] Preferably, an electric push rod is installed on the outer wall of the positioning frame. One end of the electric push rod passes through the positioning frame and is connected to the outer wall of the connecting seat. The electric push rod is used to drive the bearing seat to move horizontally.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the petrochemical pipeline cleaning mechanism not only achieves the purpose of adjusting the overall height of the cleaning mechanism in two ways to improve the applicability of the cleaning mechanism, but also achieves the purpose of cleaning the inside of the petrochemical pipeline electrically.

[0012] (1) By starting the lifting cylinder to drive the movable frame to lift, the movable frame drives the rail seat to slide up and down on the outer wall of the guide rail, so that the height of the roller brush can be adjusted to calibrate the roller brush to the side of the petrochemical pipeline at the specified height for subsequent cleaning operations, thereby improving the applicability of the cleaning mechanism.

[0013] (2) By rotating the handle, the double screw is driven to rotate. At this time, the two nut seats slide towards each other on the outer wall of the double screw, which changes the angle of the V-shaped lifting arm. The distance between the upper and lower connecting seats can be adjusted, thereby further adjusting the height of the roller brush to perform cleaning operations on the petrochemical pipeline.

[0014] (3) By calibrating the roller brush to one side of the petrochemical pipeline and applying cleaning fluid to the outer wall of the roller brush, the electric push rod is then started to drive the carrier seat to move horizontally, so that the carrier seat drives the limit block to slide at the top of the limit rail, so that the carrier seat drives the roller brush to move laterally into the petrochemical pipeline. Since the motor drives the roller brush to rotate, the roller brush can brush and clean the inner wall of the petrochemical pipeline, thereby achieving the purpose of electric cleaning of the inside of the petrochemical pipeline.

[0021] Please see Figure 1-4 An embodiment of this utility model is provided: a petrochemical pipeline cleaning mechanism, including a movable base 1, a strip seat 2 at the top of the movable base 1, a limiting rail 3 at the top of the strip seat 2, two limiting blocks 7 slidably connected to one side of the top of the limiting rail 3, a bearing seat 6 installed at the top of the limiting block 7, a connecting seat 23 installed at the bottom of the bearing seat 6, and a positioning frame 4 installed at the top of the movable base 1 on one side of the strip seat 2.

[0022] In use, the positioning frame 4 is used to position the electric push rod 5.

[0023] An electric push rod 5 is installed on the outer wall of the positioning frame 4. One end of the electric push rod 5 passes through the positioning frame 4 and is connected to the outer wall of the connecting seat 23.

[0024] In use, the electric push rod 5 is set to drive the support seat 6 to move horizontally;

[0025] A lower frame 8 is fixedly installed on one side of the top of the bearing seat 6. A lower connecting seat 10 is installed on the top of the bearing seat 6 inside the lower frame 8, and an upper connecting seat 11 is installed at the bottom of the upper frame 9.

[0026] In use, the upper connecting seat 11 and the lower connecting seat 10 are used to position the V-shaped lifting arm 12.

[0027] V-shaped lifting arms 12 are rotatably mounted on both sides of the bottom end of the upper connecting seat 11, and the bottom end of the V-shaped lifting arms 12 is rotatably connected to the top end of the lower connecting seat 10.

[0028] In use, the V-shaped lifting arm 12 is used to adjust the distance between the upper connecting seat 11 and the lower connecting seat 10;

[0029] At the center of the surface of the V-shaped lifting arm 12, a nut seat 20 is rotatably installed. A double-acting screw 21 is installed on the internal thread of the two nut seats 20. A handle 22 is installed at one end of the double-acting screw 21.

[0030] In use, the handle 22 is rotated to drive the bidirectional lead screw 21 to rotate;

[0031] An upper frame 9 is movably installed inside the lower frame 8. The top of the upper frame 9 extends to the outside of the lower frame 8 and is provided with a vertical frame 13. Two guide rails 18 are provided on the inner wall of the vertical frame 13. Two rail seats 19 are slidably connected on the outer wall of the guide rails 18. Movable frames 16 are installed on the outer walls of several rail seats 19. A lifting cylinder 17 is installed at the bottom of the vertical frame 13. The top of the lifting cylinder 17 is connected to the inner wall of the movable frame 16. A motor 14 is installed on one side of the outer wall of the upper end of the movable frame 16. One end of the motor 14 passes through the movable frame 16 and is equipped with a roller brush 15.

[0032] In this embodiment, the cleaning mechanism is first moved to one side of the petrochemical pipeline by setting the movable base 1. Then, the roller brush 15 is aligned with one side of the petrochemical pipeline, and cleaning fluid is applied to the outer wall of the roller brush 15. Subsequently, the electric push rod 5 is activated to drive the carrier 6 to move horizontally, so that the carrier 6 drives the limiting block 7 to slide on the top of the limiting rail 3. This allows the carrier 6 to move the roller brush 15 laterally into the petrochemical pipeline. Since the motor 14 drives the roller brush 15 to rotate, the roller brush 15 can brush and clean the inner wall of the petrochemical pipeline, facilitating the cleaning operation. Afterward, the lifting cylinder 17 is activated to drive the movable frame 16 to rise and fall, so that the movable frame 16 drives the rail seat 19 to slide up and down on the outer wall of the guide rail 18. The height of the roller brush 15 can be adjusted to align it with the petrochemical pipeline at a specified height. Finally, by rotating the handle 22, the double-acting screw 21 is driven to rotate. At this time, the two nut seats 20 slide towards each other on the outer wall of the double-acting screw 21, causing the angle of the V-shaped lifting arm 12 to change. This allows adjustment of the distance between the upper connecting seat 11 and the lower connecting seat 10, further adjusting the height of the roller brush 15. This pipeline cleaning mechanism is mainly designed for cleaning one type of petrochemical pipeline. The inner diameter of this type of pipeline is compatible with the outer diameter of the roller brush 15, and this type of petrochemical pipeline is a straight pipe design. If other specifications of petrochemical pipelines need to be cleaned, a cleaning mechanism composed of roller brushes 15 of the corresponding specifications can be selected for operation, thus completing the use of this cleaning mechanism.
