Description

Technical Field

[0001] This invention belongs to the field of shipbuilding technology, specifically relating to a machine and method for cleaning the inner wall of ship pipelines. Background Technology

[0002] In the construction of natural gas pipeline systems for domestic LNG carriers, the cleanliness of the pipeline inner walls is crucial for the proper functioning of the subsequent system and the normal operation of equipment and sensors passing through it. Existing processes address this by flushing, rinsing, or disassembling and grinding the pipelines, but these methods are difficult or very complex to handle internal process particles such as burrs, fly ash, molten slag, and oxide layer peeling.

[0003] Patent No. CN216621213U discloses a building engineering environmental monitoring device, including a monitoring device body, a support rod fixedly installed on the surface of the monitoring device body, a display screen fixedly installed on the surface of the support rod, a base fixedly connected to the bottom of the support rod, and a protective component provided on the side of the display screen; Patent No. CN110742387A discloses a high-efficiency roller brush for shipbuilding with easy roller replacement, including a roller and a handle, and further including a disassembly and assembly mechanism and a feeding mechanism. The disassembly and assembly mechanism includes a mounting base, a sliding sleeve, and two disassembly and assembly components. The disassembly and assembly components include a connecting sleeve, a connecting rod, a first spring, a mounting bearing, a connecting block, a rubber pad, a connecting groove, a limiting block, and a transmission rod. The feeding mechanism includes a second pipe, a first pipe, a high-pressure pump, a paint box, two support sleeves, two second springs, two support rods, and at least two through holes.

[0004] LNG natural gas pipelines are made of cryogenic stainless steel, and the connections are mainly made using butt welding. Therefore, after the weld seams are formed, the internal weld seams are difficult to clean (manual drilling into the pipeline poses a safety hazard). Pipeline welding is performed using argon arc welding combined with inert gas purging of the internal pipeline. Defects generated on the inner surface weld seams during the welding process (weld slag, spatter, oxide layer, etc.) will directly affect the subsequent cleaning and passivation project acceptance. Current traditional methods involve chemical cleaning or pipeline flushing, which is labor-intensive and resource-intensive, and significantly impacts the production cycle. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a machine and method for cleaning the inner wall of ship pipelines. The device and method of this invention improve the cleaning effect of the pipe wall by inflating the rubber ring of the roller to make the adhesive tape adhere to the pipe wall. At the same time, the support rod can extend and retract to change its length, so that the machine and device for cleaning the inner wall of the pipeline can be used for cleaning pipe walls with different inner diameters, thus improving its applicability.

[0006] To achieve the above-mentioned objectives, the technical solution provided by this invention patent is as follows:

[0007] A machine device for cleaning the inner wall of ship pipelines includes a support module and a cleaning module. The support module includes a support shaft, support rods, a fixed ball, and a roller rubber ring. The cleaning module includes an adhesive roller, a motor, and a clutch. Multiple support rods are arranged on the side of the support shaft. Each support rod is inserted and fixedly connected to one side of the fixed ball. The other side of the fixed ball is threadedly connected to the roller rubber ring, which wraps around the outside of the fixed ball. The adhesive roller includes a first adhesive roller and a second adhesive roller. The first adhesive roller is connected to the support shaft and has a clutch mounted on it. The second adhesive roller is connected to the support shaft. The support shaft is connected, and a motor is installed on the second adhesive tape roller. The roller rubber ring includes a first adhesive tape roller rubber ring and a second adhesive tape roller rubber ring. Adhesive tape outlets and adhesive tape inlets are provided on both sides of the second adhesive tape roller rubber ring and between the first adhesive tape roller rubber ring. The first adhesive tape roller and the second adhesive tape roller are connected by adhesive tape. The adhesive tape is wound on the first adhesive tape roller. The adhesive tape extends from the adhesive tape outlet and wraps around the outer surface of the roller rubber ring and enters from the adhesive tape inlet and wraps around the second adhesive tape roller. The motor drives the second adhesive tape roller to rotate, so that the adhesive tape on the first adhesive tape roller moves along the roller rubber ring and then wraps around the second adhesive tape roller.

[0008] The aforementioned support shaft is a hollow cylinder with both ends closed. An air inlet is provided on one end face of the support shaft, and multiple second connecting holes are provided on the side of the support shaft for fixing the support rod. A cleaning soft ball is provided between the first adhesive tape roller and the second adhesive tape roller on the side of the support shaft. The cleaning soft ball is connected by the support rod and is close to the adhesive tape inlet. The cleaning soft ball is used to absorb particles that fall off the adhesive tape.

[0009] The aforementioned support rod is a hollow cylinder. The interior of the support rod is connected to the support shaft through a connecting hole. Multiple rows of support rods are arranged on the side of the support shaft. The support rod includes a first connecting rod and a second connecting rod. One end of the second connecting rod is installed inside the first connecting rod and slides within the first connecting rod. The first connecting rod is fixedly connected to the side of the support shaft. A spring is provided on the support shaft inside the first connecting rod. The second connecting rod is connected to the support shaft through the spring and performs telescopic movement within the first connecting rod. The other end of the second connecting rod is connected to a connecting hole on a fixed ball. The middle of the first connecting rod and the second connecting rod is hollow.

[0010] The first connecting rod is provided with a moving groove, and the side of the second connecting rod is provided with a track moving block. The track moving block on the second connecting rod moves on the moving groove on the first connecting rod. The side of the second connecting rod near the second connecting hole is symmetrically provided with a fixing groove. The middle of the fixing groove is provided with a connecting groove. The two sides of the connecting groove have bevels that increase to the outer diameter surface of the second connecting rod. The middle side of the fixing groove is provided with a fixing pin. The moving slide key controls the extension and retraction of the fixing pin. The moving slide key is provided on the side of the second connecting rod.

[0011] The aforementioned fixed ball is spherical in shape. One end of the fixed ball is provided with a threaded hole that connects to the roller rubber ring. The other end of the fixed ball is provided with a first connecting hole. A cylindrical limiting plate is provided in the first connecting hole. A cavity is provided between the limiting plate and the first connecting hole. A pressing plate is provided at one end of the threaded hole. The pressing plate extends into the limiting plate and communicates with the threaded hole. A rubber block is provided in the limiting plate. Both sides of the rubber block are connected to one end of the insert strip. The other end of the insert strip extends to the end of the limiting plate. A frustum-shaped hole is provided in the middle of the rubber block.

[0012] The insert is generally arc-shaped, with a fixing hole at the end of the insert and telescopic holes symmetrically arranged at the end of the limiting plate. One end of the insert extends into the limiting plate through the telescopic hole. When the second connecting rod is inserted into the limiting plate and causes the rubber block to move toward the extrusion plate, the extrusion plate enters the frustum-shaped hole in the middle of the rubber block. The extrusion plate extrudes the rubber block, and the rubber block drives the insert to move toward both sides of the limiting plate. The insert extends from the telescopic hole of the limiting plate into the connecting groove in the fixing groove.

[0013] The first and second adhesive tape roller rubber rings are hollow cylinders. The interiors of the first and second adhesive tape roller rubber rings are hollow. Supporting cylinders are provided at both ends of the first adhesive tape roller rubber ring. Multiple rows of curved flat strips are evenly arranged on the inner side of the first adhesive tape roller rubber ring, and a row of curved flat strips is provided on the inner side of the second adhesive tape roller rubber ring. A connecting bolt is provided in the middle of the curved flat strip. The connecting bolt is hollow and is connected to the threaded hole of the fixing ball.

[0014] A method for cleaning the inner wall of ship pipelines, the method specifically includes the following steps:

[0015] The first step is to prepare a machine device for cleaning the inner wall of ship pipelines. This device includes a support module and a cleaning module. The support module includes a support shaft, support rods, a fixed ball, and a roller rubber ring. The cleaning module includes an adhesive roller, a motor, and a clutch. Multiple support rods are arranged on the side of the support shaft. The support rods are inserted and fixedly connected to one side of the fixed ball. The other side of the fixed ball is threadedly connected to the roller rubber ring, which wraps around the outside of the fixed ball. The adhesive roller includes a first adhesive roller and a second adhesive roller. The first adhesive roller is connected to the support shaft and has a clutch installed on it. The second adhesive roller... The cylinder is connected to the support shaft. A motor is installed on the second adhesive tape roller. The roller rubber ring includes a first adhesive tape roller rubber ring and a second adhesive tape roller rubber ring. Adhesive tape outlets and adhesive tape inlets are provided on both sides of the second adhesive tape roller rubber ring and between the first adhesive tape roller rubber ring. The first adhesive tape roller and the second adhesive tape roller are connected by adhesive tape. The adhesive tape is wound on the first adhesive tape roller. The adhesive tape extends from the adhesive tape outlet and wraps around the outer surface of the roller rubber ring and enters from the adhesive tape inlet and wraps around the second adhesive tape roller. The motor drives the second adhesive tape roller to rotate, so that the adhesive tape on the first adhesive tape roller moves along the roller rubber ring and then wraps around the second adhesive tape roller.

[0016] The second step is to assemble the pipe inner wall cleaning machine, place it inside the pipe to be cleaned, and inflate the roller rubber ring through the air inlet of the support shaft. The gas passes through the support rod and the fixed ball to the roller rubber ring, making the roller rubber ring fit against the inner wall of the pipe. Then, seal the air inlet to check whether the roller rubber ring is leaking. When it is confirmed that the roller rubber ring is not leaking, deflate the roller rubber ring and install the pipe inner wall cleaning machine at both ends of the traveling trolley.

[0017] The third step is to send the pipe inner wall cleaning machine at one end of the traveling trolley to the pipe inner wall cleaning weld, and then inflate the pipe inner wall cleaning machine at the other end of the traveling trolley through the air inlet of the support shaft to make the roller rubber ring fit against the inner wall of the pipe; by connecting the air hose and the air inlet of the support shaft for inflation, the air hose is not disconnected from the pipe inner wall cleaning machine when the pipe inner wall cleaning machine is working, and the inflation pressure in the roller rubber ring is maintained to make the roller rubber ring fit against the inner wall of the pipe.

[0018] Fourth step, start the motor on the second adhesive tape roller. The motor drives the second adhesive tape roller to rotate, so that the adhesive tape on the first adhesive tape roller is wrapped around the rubber ring of the roller and onto the second adhesive tape roller. The adhesive tape contacts the inner wall of the pipe and cleans the inner wall of the pipe. The cleaning soft rubber ball at the adhesive tape inlet absorbs the particles that fall off the adhesive tape. When all the adhesive tape is wrapped around the second adhesive tape roller, the motor stops running.

[0019] Fifth step: After the pipe weld seam cleaning is completed, turn off the motor, deflate the roller rubber ring through the air inflator hose, then move the pipe inner wall cleaning machine to the next pipe inner wall weld seam to be cleaned, inflate it through the air inflator hose and clean it until all inner walls are cleaned. Then deflate the pipe inner wall cleaning machine and remove it from the pipe to complete the pipe inner wall cleaning.

[0020] The aforementioned traveling trolley is connected to the pipe inner wall cleaning machine via a rotating shaft. The rotating shaft is hinged to the traveling trolley. When the traveling trolley drives the pipe inner wall cleaning machine through the pipe bend, the angle between the rotating shaft and the traveling trolley changes, allowing the pipe inner wall cleaning machine to pass through the pipe bend.

[0021] When the pipe cleaning machines installed at both ends of the aforementioned traveling trolley clean the inner wall of the pipe, the adhesive tape on the pipe cleaning machines at both ends of the traveling trolley moves in opposite directions.

[0022] Based on the above technical solutions, the invention patent's machine and method for cleaning the inner walls of ship pipelines has achieved the following technical advantages through practical application:

[0023] 1. The present invention provides a cleaning machine for the inner wall of ship pipelines. The roller rubber ring is inflated to make the adhesive tape adhere to the pipe wall, which improves the cleaning effect. At the same time, the support rod can extend and retract to change its length, making the cleaning machine suitable for cleaning pipe walls with different inner diameters, thus improving its applicability.

[0024] 2. The present invention relates to a device for cleaning the inner wall of a ship's pipeline. By setting a rubber block inside the fixed ball, the device compresses and drives the insert strip to move, thereby improving the sealing performance of the fixed ball and the airtightness of the rubber ring of the roller. This ensures that the device does not leak air during operation and improves its operational stability.

[0025] 3. The present invention provides a method for cleaning the inner wall of ship pipelines. By using a telescopic support rod to support the rubber ring of the roller, the cleaning device can pass through the pipe bends at different angles to achieve cleaning of the bends in the pipe.

[0043] To make the objectives, technical solutions, and advantages of this invention clearer, the following description is provided with reference to the accompanying drawings.

[0044] The invention is described using specific examples shown. However, it should be understood that these descriptions are merely exemplary.

[0045] This description is intended not to limit the scope of the invention. Furthermore, in the following description, descriptions of well-known structures and techniques are omitted to avoid unnecessarily obscuring the concept of the invention.

[0046] like Figure 1-17 The present invention pertains to a machine device for cleaning the inner wall of ship pipelines. This device includes a support module and a cleaning module. The support module includes a support shaft 1, support rods 2, a fixed ball 3, and a roller rubber ring 4. The cleaning module includes an adhesive roller, a motor 53, and a clutch 54. Multiple support rods 2 are arranged on the side of the support shaft 1. Each support rod 2 is inserted and fixedly connected to one side of the fixed ball 3. The other side of the fixed ball 3 is threadedly connected to the roller rubber ring 4, which wraps around the outside of the fixed ball 3. The adhesive roller includes a first adhesive roller and a second adhesive roller. The first adhesive roller 51 is connected to the support shaft 1 and a clutch 54 is mounted on it. The second adhesive roller 52 is connected to the support shaft 1 and a motor 53 is mounted on it. The roller rubber ring 4 includes a first adhesive roller rubber ring 41 and a second adhesive roller rubber ring 42. An adhesive tape outlet and an adhesive tape inlet are provided on both sides of the rubber ring 42 and between the first adhesive tape roller rubber ring 41. The first adhesive tape roller 51 and the second adhesive tape roller 52 are connected by adhesive tape 55. The adhesive tape 55 is wrapped around the first adhesive tape roller 51. The adhesive tape 55 extends from the adhesive tape outlet and wraps around the outer surface of the roller rubber ring 4, and enters from the adhesive tape inlet and wraps around the second adhesive tape roller 52. The motor 53 drives the second adhesive tape roller 52 to rotate, so that the adhesive tape 55 on the first adhesive tape roller 51 moves along the roller rubber ring 4 and wraps around the second adhesive tape roller 52. The roller rubber ring 4 is inflated to make the adhesive tape 55 adhere to the pipe wall, which improves the cleaning effect of the pipe wall. At the same time, the support rod 2 can extend and retract to change its length, so that the pipe inner wall cleaning machine can be used to clean pipe walls with different inner diameters, which improves its applicability. When the motor 53 starts, the clutch 54 enables the adhesive tape 55 to start and run smoothly, which improves the stability of the operation of the adhesive tape 55 and improves the cleaning effect of the adhesive tape 55.

[0047] The support shaft 1 is a hollow cylinder with both ends closed. An air inlet 11 is provided on one end face of the support shaft, and multiple second connecting holes are provided on the side of the support shaft for fixing the support rod 2. A cleaning soft ball 31 is positioned between the first and second adhesive rollers on the side of the support shaft. The cleaning soft ball 31 is connected to the support rod 2 and is located near the adhesive tape inlet. The cleaning soft ball 31 is used to absorb particles detached from the adhesive tape 55. The support rod connecting the cleaning soft ball 31 is identical to the support rod connecting the fixed ball 3 except for the fixing groove 23, connecting groove 24, and moving slide key 25. The cleaning soft ball 31 is connected to the end of the second connecting rod 22 and is replaceable.

[0048] like Figure 8 As shown, the support rod 2 is a hollow cylinder. The interior of the support rod 2 is connected to the support shaft 1 through a connecting hole. Multiple rows of support rods 2 are arranged on the side of the support shaft 1. The support rod 2 includes a first connecting rod 21 and a second connecting rod 22. One end of the second connecting rod 22 is installed inside the first connecting rod 21 and slides inside the first connecting rod 21. The first connecting rod 21 is fixedly connected to the side of the support shaft 1. A spring is provided on the support shaft 1 inside the first connecting rod 21. The second connecting rod 22 is connected to the support shaft 1 through the spring. The second connecting rod 22 moves telescopically within the first connecting rod 21. The other end of the second connecting rod 22 is connected to the connecting hole on the fixed ball 3. The middle of the first connecting rod 21 and the second connecting rod 22 is hollow. The support rod 2 can move telescopically and can pass through the bends inside the pipe to achieve cleaning at the bends of the inner wall of the pipe.

[0049] The first connecting rod 21 is provided with a moving groove, and the side of the second connecting rod 22 is provided with a track moving block 26. The track moving block 26 on the second connecting rod 22 moves on the moving groove on the first connecting rod 21. The side of the second connecting rod 22 near the second connecting hole is symmetrically provided with a fixing groove 23. The middle of the fixing groove 23 is provided with a connecting groove 24. The two sides of the connecting groove 24 have bevels that increase to the outer diameter surface of the second connecting rod 22. A fixing pin is provided on the side of the middle of the fixing groove 23. The moving slide key 25 controls the extension and retraction of the fixing pin. The moving slide key 25 is provided on the side of the second connecting rod 22. The track moving block 26 moves in the moving groove and limits the second connecting rod 22 to prevent the second connecting rod 22 from rotating when it extends and retracts, so that the second connecting rod 22 is stably connected to the fixing ball 3.

[0050] like Figure 6 and Figure 7As shown, the fixed ball 3 is spherical in shape. One end of the fixed ball 3 is provided with a threaded hole 310 to connect with the roller rubber ring 4. The other end of the fixed ball 3 is provided with a first connecting hole 32. A cylindrical limiting plate 33 is provided inside the first connecting hole 32. A cavity is provided between the limiting plate 33 and the first connecting hole 32. A pressing plate 34 is provided at one end of the threaded hole 310. The pressing plate 34 extends into the limiting plate 33 and communicates with the threaded hole 310. A rubber block 35 is provided inside the limiting plate 33. The two sides of the rubber block 35 are respectively connected to one end of the insert 36. The other end of the insert 36 extends to the end of the limiting plate 33. A frustum-shaped hole is provided in the middle of the rubber block 35. The movement space of the insert 36 on the limiting plate 33 is somewhat restricted. It can only move up and down precisely at the opening at the end of the limiting plate 33. At the same time, there is a pull ring on the rubber block for convenient maintenance. The limiting plate 33 is cylindrical with a rubber layer inside to facilitate sealing; the fixing ball 3 also serves as a quick connector, a detachable part, and an air inlet for the roller rubber ring; the purpose is to ensure the stability of the entire device during operation.

[0051] The insert 36 is generally arc-shaped, with a fixing hole 37 at its end. The limiting plate 33 has symmetrical telescopic holes 38 at its end. One end of the insert 36 extends into the limiting plate 33 through the telescopic hole 38. When the second connecting rod 22 is inserted into the limiting plate 33, causing the rubber block 35 to move towards the extrusion plate 34, the extrusion plate 34 enters the frustum-shaped hole in the middle of the rubber block 35, extruding the rubber block 35. The rubber block 35 then drives the insert 36 to move towards both sides of the limiting plate 33. The telescopic hole 38 of plate 33 extends into the connecting groove 24 in the fixing groove 23; the sliding key 25 of the first connecting rod 21 controls the fixing pin to insert into the fixing hole of the insert 36, fixing the insert 36. When the fixing ball 3 needs to be separated from the support rod 2, the sliding key 25 controls the fixing pin to be pulled out from the fixing hole, and the fixing ball 3 is rotated, so that the end of the insert 36 moves along the arc trajectory of the connecting groove 24, so that the insert 36 retracts into the limiting plate 33. At the same time, the rubber block 35 squeezes the second connecting rod 22 out of the fixing ball 3.

[0052] like Figure 5As shown, the first adhesive tape roller rubber ring 41 and the second adhesive tape roller rubber ring 42 are hollow cylinders. The interiors of the first adhesive tape roller rubber ring 41 and the second adhesive tape roller rubber ring 42 are hollow. Supporting cylinders 43 are provided at both ends of the first adhesive tape roller rubber ring 41. Multiple rows of curved flat strips 44 are evenly arranged on the inner side of the first adhesive tape roller rubber ring 41. A row of curved flat strips 44 is provided on the inner side of the second adhesive tape roller rubber ring 42. A connecting bolt 45 is provided in the middle of the curved flat strip 44. The connecting bolt 45 is hollow and is connected to the threaded hole 310 of the fixed ball 3. The supporting cylinders 43 support the movement of the adhesive tape at the adhesive tape inlet and outlet, preventing contact with the machine. The curved flat strips 44 used for connecting the supporting cylinders 43 on both sides of the first adhesive tape roller rubber ring 41 to the nearest fixed ball 3 and all the fixed ball 3 connections are made of rigid material. Since the curved flat strips 44 connecting the three fixed balls 3 in the middle are made of flexible rubber material, they can be extended.

[0053] like Figure 10-16 As shown, a method for cleaning the inner wall of a ship's pipeline includes the following steps:

[0054] The first step is to prepare a machine device for cleaning the inner wall of ship pipelines. This device includes a support module and a cleaning module. The support module includes a support shaft 1, support rods 2, a fixed ball 3, and a roller rubber ring 4. The cleaning module includes an adhesive roller, a motor 53, and a clutch 54. Multiple support rods 2 are arranged on the side of the support shaft 1. The support rods 2 are connected to one side of the fixed ball 3, and the other side of the fixed ball 3 is connected to the roller rubber ring 4. The roller rubber ring 4 wraps around the outside of the fixed ball 3. The adhesive roller includes a first adhesive roller and a second adhesive roller. The first adhesive roller 51 is connected to the support shaft 1, and a clutch 54 is installed on the first adhesive roller 51. The second adhesive roller 52 is connected to the support shaft 1. A motor 53 is installed on the second adhesive roller 52. The roller rubber ring 4 includes a first adhesive roller rubber ring 41 and a second adhesive roller rubber ring 42. Adhesive tape outlet and adhesive tape inlet are provided on both sides of the second adhesive roller rubber ring 42 and between the first adhesive roller rubber ring 41. The first adhesive roller 51 and the second adhesive roller 52 are connected by adhesive tape 55. Adhesive tape 55 is wrapped around the first adhesive roller 51. Adhesive tape 55 extends from the adhesive tape outlet and wraps around the outer surface of the roller rubber ring 4 and enters from the adhesive tape inlet and wraps around the second adhesive roller 52. The motor 53 drives the second adhesive roller 52 to rotate, so that the adhesive tape 55 on the first adhesive roller 51 moves along the roller rubber ring 4 and then wraps around the second adhesive roller 52.

[0055] The second step is to assemble the pipe inner wall cleaning machine 8 and place it inside the pipe to be cleaned. Inflate the roller rubber ring 4 through the air inlet 11 of the support shaft 1. The gas passes through the support rod 2 and the fixed ball 3 to the roller rubber ring 4, making the roller rubber ring 4 fit against the inner wall of the pipe. Then seal the air inlet 11 to check whether the roller rubber ring 4 is leaking. When it is confirmed that the roller rubber ring 4 is not leaking, release the air from the roller rubber ring 4 and install the pipe inner wall cleaning machine 8 at both ends of the traveling trolley 6.

[0056] The third step is to send the pipe inner wall cleaning machine 8 at one end of the traveling trolley to the pipe inner wall cleaning weld, and then inflate the pipe inner wall cleaning machine 8 at the other end of the traveling trolley 6 through the air inlet 11 of the support shaft 1 to make the roller rubber ring 4 fit against the inner wall of the pipe; by connecting the air inlet hose and the air inlet 11 of the support shaft 1 to inflate, when the pipe inner wall cleaning machine 8 is working, the air inlet hose is not disconnected from the pipe inner wall cleaning machine 8, and the inflation pressure in the roller rubber ring 4 is maintained to make the roller rubber ring 4 fit against the inner wall of the pipe.

[0057] Fourth step, start the motor 53 on the second adhesive tape roller 52. The motor 53 drives the second adhesive tape roller 52 to rotate, so that the adhesive tape 55 on the first adhesive tape roller 51 is wrapped around the roller rubber ring 4 onto the second adhesive tape roller 52. The adhesive tape 55 contacts the inner wall of the pipe and cleans the inner wall of the pipe. The cleaning soft rubber ball 31 at the adhesive tape inlet adsorbs the particles that fall off the adhesive tape 55. When the adhesive tape is completely wrapped around the second adhesive tape roller 52, the motor stops running.

[0058] Fifth step: After the pipe weld seam is cleaned, turn off the motor 53, release the air from the roller rubber ring 4 through the air inflator hose, then move the pipe inner wall cleaning machine 8 to the next pipe inner wall weld seam to be cleaned, and then inflate it through the air inflator hose to clean it until all inner walls are cleaned. Then release the air from the pipe inner wall cleaning machine 8 and remove the pipe inner wall cleaning machine 8 from the pipe to complete the pipe inner wall cleaning.

[0059] The traveling trolley 6 is connected to the pipe inner wall cleaning machine 8 via a rotating shaft 7. The rotating shaft 7 is hinged to the traveling trolley 6. When the traveling trolley 6 drives the pipe inner wall cleaning machine 8 through the pipe bend, the angle between the rotating shaft 7 and the traveling trolley 6 changes, allowing the pipe inner wall cleaning machine 8 to pass through the pipe bend.

[0060] When the pipe cleaning machines 8 installed at both ends of the traveling trolley 6 clean the inner wall of the pipe, the adhesive tape 55 on the pipe cleaning machines 8 at both ends of the traveling trolley 6 moves in opposite directions; the pipe cleaning machines 8 installed at both ends of the traveling trolley 6 rotate in opposite directions and cancel each other out, so that the traveling trolley 6 can better drive the pipe cleaning machines 8 to move, thus improving the cleaning effect of the pipe wall.

[0061] A speed sensor is also installed on the motor 53 and the first adhesive tape roller 51. When the motor 53 cannot drive the first adhesive tape roller 51 to rotate, that is, when all the adhesive tape on the first adhesive tape roller 51 is wrapped around the second adhesive tape roller 52, the speed sensor on the first adhesive tape roller 51 will send a signal back to the motor 53, causing the motor 53 to stop running. This means that all the adhesive tape 55 has been used up and the adhesive tape 55 on the roller needs to be replaced. This prevents the motor 53 from being overloaded and avoids damage, thus improving its service life.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit it; although the present invention has been described in detail with reference to preferred embodiments, the scope of the invention is not limited to this.

[0063] Those skilled in the art should understand that modifications can still be made to the specific implementation of the invention or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of the present invention, and all such modifications and substitutions should be covered within the scope of the technical solution claimed in the present invention.
