Description

Technical Field

[0001] This utility model relates to a cleaning device, specifically a gas pipeline inner wall cleaning device, belonging to the field of pipeline cleaning technology. Background Technology

[0002] During long-term use, gas pipelines accumulate dirt, rust, and other impurities on their inner walls. These impurities not only affect the efficiency of gas transmission but may also cause pipeline blockages and corrosion, seriously threatening the safety of gas transmission. Therefore, it is necessary to clean the inner walls of gas pipelines regularly.

[0003] Chinese Patent Publication CN221675224U discloses a gas pipeline inner wall cleaner for gas engineering. It uses water jets from a high-pressure nozzle to flush the inner wall of the pipeline and brushes to clean the inner wall, effectively cleaning the dirt on the inner wall of the gas pipeline and improving cleaning efficiency.

[0004] The aforementioned patented technology cannot adapt to different pipe diameters in practical use. When cleaning gas pipes of different diameters is required, different specifications of cleaning equipment need to be replaced, increasing the cost of use. Furthermore, when the brushes wear out severely after a period of use or are damaged due to cleaning special impurities, the replacement process is very cumbersome, reducing the applicability of the gas pipe inner wall cleaning equipment. Therefore, a gas pipe inner wall cleaning device is proposed here. Utility Model Content

[0005] This utility model proposes a gas pipeline inner wall cleaning device to solve the problems of existing technologies that cannot automatically adapt to different pipeline diameters and require cumbersome brush replacement.

[0006] This utility model is achieved through the following technical solution: a gas pipeline inner wall cleaning device, including a connecting frame, wherein an adjustment mechanism is provided inside the connecting frame;

[0007] The adjustment mechanism includes a positioning plate, the right end of which is fixedly connected to the left end of the connecting frame. A threaded rod is rotatably connected inside the positioning plate. A servo motor is fixedly connected to the right end of the threaded rod. A moving block is threadedly connected to the outer surface of the threaded rod. The moving block is slidably connected to the inside of the connecting frame. Four adjustment blocks are provided on the outer surface of the connecting frame. Two force transmission blocks are rotatably connected to the outer surface of each adjustment block. The inner wall of each set of force transmission blocks is rotatably connected to the outer surface of the moving block.

[0008] The outer surface of the connecting frame is provided with loading and unloading components.

[0009] An auxiliary bearing is fitted onto the outer surface of the threaded rod, and the auxiliary bearing is embedded inside the connecting frame.

[0010] Each of the adjustment blocks has a stabilizing block fixedly connected to its left side, and each stabilizing block is slidably connected to the inside of the positioning plate.

[0011] The connecting frame has a heat dissipation groove inside, and a mounting shell is fixedly connected to the right end of the connecting frame.

[0012] The loading and unloading assembly includes four auxiliary blocks. The inner wall of each auxiliary block is fixedly connected to the outer surface of an adjusting block. A brush is slidably connected inside each adjusting block. A limit rod is slidably connected inside each auxiliary block. An auxiliary ring is fixedly connected to the outer surface of each limit rod. The end of each limit rod away from the auxiliary ring passes through the brush and extends into the interior of the auxiliary block. A return spring is fixedly connected to the end of each auxiliary ring away from the brush.

[0025] 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 a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0026] Please see Figures 1-4 This utility model provides a gas pipeline inner wall cleaning device, including a connecting frame 1, and an adjustment mechanism 2 is provided inside the connecting frame 1;

[0027] The adjusting mechanism 2 includes a positioning plate 201. The right end of the positioning plate 201 is fixedly connected to the left end of the connecting frame 1. A threaded rod 202 is rotatably connected inside the positioning plate 201. An auxiliary bearing 4 is sleeved on the outer surface of the threaded rod 202. The auxiliary bearing 4 is embedded inside the connecting frame 1. The auxiliary bearing 4 can reduce the friction generated by the threaded rod 202 when rotating, making the threaded rod 202 more sensitive when rotating. It can also reduce the wear rate of the threaded rod 202 when rotating and increase the service life of the threaded rod 202.

[0028] A servo motor 203 is fixedly connected to the right end of the threaded rod 202. A moving block 204 is threadedly connected to the outer surface of the threaded rod 202. The moving block 204 is slidably connected to the inside of the connecting frame 1. Four adjusting blocks 205 are provided on the outer surface of the connecting frame 1. A stabilizing block 5 is fixedly connected to the left side of each adjusting block 205. Each stabilizing block 5 is slidably connected to the inside of the positioning plate 201. The stabilizing block 5 can move simultaneously with the adjusting block 205 and improves the stability of the adjusting block 205 during movement by relying on the friction generated by itself on the positioning plate 201 during the movement. It can also limit the maximum moving distance of the adjusting block 205.

[0029] Two force transmission blocks 206 are rotatably connected to the outer surface of each adjustment block 205. The inner wall of each set of force transmission blocks 206 is rotatably connected to the outer surface of the moving block 204. A heat dissipation groove 6 is provided inside the connecting frame 1. A mounting shell 7 is fixedly connected to the right end of the connecting frame 1. The heat dissipation groove 6 can improve the heat dissipation speed of the servo motor 203 inside the connecting frame 1, and can also be quickly connected to external power equipment by relying on the mounting shell 7, increasing the convenience of use.

[0030] The outer surface of the connecting frame 1 is provided with a loading and unloading assembly 3, which includes four auxiliary blocks 301. The inner wall of each auxiliary block 301 is fixedly connected to the outer surface of the adjusting block 205. A brush 302 is slidably connected inside each adjusting block 205. A limit rod 303 is slidably connected inside each auxiliary block 301. An auxiliary ring 304 is fixedly connected to the outer surface of each limit rod 303. The end of each limit rod 303 away from the auxiliary ring 304 passes through the brush 302 and extends into the interior of the auxiliary block 301. The end of each auxiliary ring 304 away from the brush 302 is fixedly connected to... Each brush 302 is fixedly connected to the inner wall of the auxiliary block 301 by a return spring 305. The brush 302 is fixed in the auxiliary block 301 by the limiting rod 303. The brush 302 can also be moved out of the adjusting block 205 by pulling the limiting rod 303. At the same time, the return spring 305 is compressed, which will slide the brush 302 out of the auxiliary block 301 and put the new brush 302 into the auxiliary block 301. The rebound force generated by the return spring 305 will drive the limiting rod 303 to reset, so that it can be inserted into the brush 302 again, thereby completing the limiting of the brush 302.

[0031] Each limit rod 303 is fixedly connected to a stop block 8 at one end near the auxiliary ring 304, and each stop block 8 is fixedly connected to an auxiliary handle 9 on the side away from the limit rod 303. The cooperation of the stop block 8 and the auxiliary handle 9 can provide a good force point for the limit rod 303, increasing the convenience when pulling the limit rod 303. The stop block 8 can be moved by pulling the auxiliary handle 9.

[0032] When using this utility model: First, connect the servo motor 203 to the power supply, and connect the connecting frame 1 to the external power equipment through the mounting shell 7. Then, insert the connecting frame 1 into the gas pipeline, and drive the connecting frame 1 to rotate through the external power equipment, thereby cleaning the inner wall of the gas pipeline by relying on the rotation of the brush 302.

[0033] When the diameter of the cleaning equipment needs to be adjusted, the servo motor 203 is started. The power generated by the servo motor 203 drives the threaded rod 202 to rotate. The auxiliary bearing 4 can increase the sensitivity of the threaded rod 202 during rotation and make the moving block 204 move repeatedly in the connecting frame 1. During the movement of the moving block 204, it will transmit the power to the adjusting block 205 through the force transmission block 206, thereby causing the adjusting block 205 to move outward. At this time, the stabilizing block 5 and the positioning plate 201 cooperate to increase the smoothness of the movement of the adjusting block 205, thereby causing the brush 302 to move at the same time, so that the diameter of the cleaning equipment changes, so as to adapt to the cleaning work of gas pipelines of different diameters.

[0034] When brush 302 needs to be replaced, pull the auxiliary handle 9. The auxiliary handle 9 moves the stop block 8, which in turn moves the limit rod 303 out of the brush 302. At the same time, the auxiliary ring 304 compresses the return spring 305. At this time, the brush 302 is no longer limited by the limit rod 303. Then, quickly remove the brush 302 from the adjusting block 205. After replacement, release the auxiliary handle 9. The rebound force generated by the return spring 305 resets the auxiliary ring 304 and pushes the limit rod 303 back into the brush 302, thus completing the limitation of the new brush 302. The continuous pressure of the return spring 305 also increases the firmness of the brush 302 in the limitation, realizing the ability to quickly replace the brush 302 and increasing the effectiveness of the gas pipeline inner wall cleaning equipment.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
