Description

Technical Field

[0001] The invention belongs to the technical field of pipeline cleaning, and in particular relates to an in-pipe cleaning robot for pipeline construction. Background Art

[0002] A gas pipeline is a pipeline that transports natural gas from the extraction site or processing plant to urban gas distribution centers or industrial enterprise users.

[0003] After the construction of the existing municipal gas pipeline, there will be a lot of garbage and dust inside the pipeline. At present, the municipal government mostly uses pipe cleaning robots to clean the garbage and dust inside the construction pipeline. However, the dust removal effect of the existing pipe cleaning robots is poor, and the garbage and dust inside the pipeline cannot be cleaned well, resulting in unclean inside the gas pipeline in the later stage, affecting the safety of the pipeline. In response to the above technical problems, a Chinese patent with patent announcement number CN215198737U is used to scrape impurities on the inner wall of the pipeline by a scraper, but the rotation axis of the scraper cannot coincide with the axis of the pipeline during use, so that the scraper can only scrape the position under the pipeline that the scraper can contact, and the cleaning effect of the pipeline is poor.

[0006] Further technical solution: Multiple groups of spaced-apart pillars are fixedly mounted on the sides of the bottom plate and the top plate that are away from each other, rollers are rotatably mounted on the ends of the pillars and one group of rollers is driven by a motor.

[0007] Further technical solution: the axis of the output shaft of the second rotating power member is parallel to the axis of the rotating tube, a gear is fixedly installed on the output end of the second rotating power member, the gear is meshed with a second gear ring fixedly installed on the rotating tube, and the second gear ring is coaxially arranged with the rotating tube.

[0008] Further technical solution: A temporary storage box is fixedly installed at the output end of the second telescopic member, the opening of the temporary storage box faces away from the second telescopic member, and a scraper is fixedly installed at the opening of the temporary storage box. Both ends of the scraper are provided with a shielding protrusion structure connected to the temporary storage box. An angle is set between the scraper and the end face of the temporary storage box, and the installation position and angle direction of the two sets of scrapers on the temporary storage box are opposite.

[0009] Further technical solution: A baffle is slidably installed on the side wall of the temporary storage box, the baffle is located at the opening of the temporary storage box, and a first permanent magnet is fixedly installed at one end of the baffle located in the temporary storage box. The first permanent magnet is used in conjunction with an electromagnet fixedly installed on the side of the baffle.

[0010] Further technical solution: two groups of parallel distributed brackets are fixedly installed on the surface of the bottom plate away from the top plate, the brackets are L-shaped structures and the collection box is slidably installed on the brackets, a third telescopic part is fixedly installed on the surface of the bottom plate away from the top plate, a second permanent magnet is fixedly installed on the output end of the third telescopic part, and the second permanent magnet is used in conjunction with a connecting iron plate fixedly installed on the side of the collection box.

[0011] Further technical solution: a telescopic rod is fixedly installed on the surface of the bottom plate away from the top plate, a support plate is fixedly installed on one end of the telescopic rod away from the bottom plate, a vertical tube is fixedly installed on the support plate, the vertical tube and the rotating shaft are distributed in the same vertical plane, the vertical tube is connected to the dust suction hose, a ball is rotatably installed on the vertical tube, and the end surface of the vertical tube away from the bottom plate is higher than the bottom surface of the ball.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. Place the bottom plate in the pipe to be cleaned, and then the first telescopic member drives the top plate to move upward until the roller on the top plate contacts the upper part of the pipe. At this time, the installation of the bottom plate and the top plate is completed to ensure the stability of the device during subsequent impurity cleaning. During the upward movement of the top plate, due to the presence of the two sets of racks and the first gear ring, the slider can move with the top plate and can always keep the slider on the symmetrical plane of the bottom plate and the top plate, so that the positioning of the pipeline axis can be completed directly. At the same time, the diameter of the pipeline can be determined according to the extended length of the first telescopic member. At this time, the rotating shaft and the rotating tube are coaxially distributed with the pipeline, thereby ensuring that the subsequent scraper can fully contact the inner wall of the pipeline, realize comprehensive cleaning of the inner wall of the pipeline, and improve the cleaning effect.

[0014] 2. When the scraper contacts the inner wall of the pipe to clean the impurities, the angle between the scraper and the end face of the temporary storage box faces the front side of the scraper's rotation direction. When the scraper rotates around the inside of the pipe, the impurities on the inner wall of the pipe are scraped off by the scraper. The scraped impurities will fall onto the scraper under the action of gravity. The raised shielding structure on both sides of the scraper reduces the probability of impurities falling. Then the impurities follow the scraper into the temporary storage box. When the scraper rotates to the top of the inner wall of the pipe, the vertical downward projection of the contact position between the scraper and the inner wall of the pipe exceeds the opening area of ​​the temporary storage box. At this time, part of the impurities scraped off by the scraper will fall directly to the bottom of the pipe. The temporary storage box collects and stores a large amount of impurities scraped off the inner wall of the pipe in time, reduces the number of impurities falling to the bottom of the pipe, and avoids the dispersion of impurities after collision, which is beneficial to the subsequent cleaning of impurities and further improves the dust removal effect in the pipe.

[0015] 3. When the two groups of scrapers are in contact at the bottom of the pipe, the impurities on the bottom of the pipe will be scooped up by the two groups of scrapers and remain on the two groups of scrapers. Then the second telescopic member contracts, and the rotating shaft and the rotating tube rotate in coordination to ensure that the ends of the two groups of scrapers are always in contact and move upward a set distance. Then the collecting box moves to the bottom of the scraper. At this time, the rotating shaft and the rotating tube rotate in opposite directions to separate the two groups of scrapers. At this time, the impurities on the scraper can fall downward into the collecting box. At the same time, the side magnetic poles of the electromagnet and the first permanent magnet that are close to each other become the same, so that the baffle opens, and the impurities in the temporary storage box fall into the collecting box synchronously. The impurities accumulated at the bottom of the pipe can be clamped and collected by the two groups of scrapers to avoid large particles of impurities remaining at the bottom of the pipe. The residual dust impurities can be sucked and collected by the exhaust fan, which further improves the effect of cleaning impurities in the pipe. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0024] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0025] like Figure 1-Figure 3 As shown, a pipe cleaning robot for pipeline construction provided by the present invention comprises a bottom plate 1 and a top plate 3, a lighting lamp and a camera are arranged on the bottom plate 1, the bottom plate 1 and the top plate 3 are fixedly connected by multiple groups of first telescopic members 2, multiple groups of rollers 5 are arranged on the sides of the bottom plate 1 and the top plate 3 away from each other, multiple groups of spaced pillars 4 are fixedly installed on the sides of the bottom plate 1 and the top plate 3 away from each other, the rollers 5 are rotatably installed on the ends of the pillars 4 and one group of rollers 5 is driven by a motor, a U-shaped mounting frame 6 is fixedly installed in the middle of the bottom plate 1, a groove for the mounting frame 6 to pass through is opened on the top plate 3, a slider 7 is slidably installed on the mounting frame 6, a first gear ring 9 is rotatably installed on the slider 7, racks 8 are meshed on both sides of the first gear ring 9, two groups of racks 8 are fixedly installed on the bottom plate 1 and the top plate 3 respectively, and the slider 7 is located on the symmetrical planes of the bottom plate 1 and the top plate 3; A rotating shaft 10 and a rotating tube 17 are rotatably mounted on the slider 7. The rotating shaft 10 and the rotating tube 17 are coaxially arranged with the first gear ring 9. A first rotating power member 18 and a second rotating power member 19 are fixedly mounted on the slider 7 to drive the rotating shaft 10 and the rotating tube 17 to rotate respectively. The axis of the output shaft of the second rotating power member 19 is parallel to the axis of the rotating tube 17. A gear 20 is fixedly mounted on the output end of the second rotating power member 19. The gear 20 is meshed with a second gear ring 21 fixedly mounted on the rotating tube 17. The second gear ring 21 is coaxially arranged with the rotating tube 17. A second telescopic member 11 is fixedly mounted on the ends of the rotating tube 17 and the rotating shaft 10. The second telescopic member 11 is distributed along the radial direction of the first gear ring 9 and a scraper 13 is arranged at the output end of the second telescopic member 11. A collecting box 23 is provided on the surface of the bottom plate 1 away from the top plate 3 , and an exhaust fan 29 is fixedly mounted on the bottom plate 1 . The exhaust fan 29 is connected to a dust suction hose 30 and a dust outlet pipe 33 , and the dust outlet pipe 33 is connected to the collecting box 23 .

[0026] In actual application of this embodiment, the bottom plate 1 is placed in the pipe to be cleaned, and then the first telescopic member 2 drives the top plate 3 to move upward until the roller 5 on the top plate 3 contacts the upper part of the pipe. At this time, the installation of the bottom plate 1 and the top plate 3 is completed, ensuring the stability of the device during subsequent impurity cleaning. During the upward movement of the top plate 3, due to the presence of the two sets of racks 8 and the first gear ring 9, the slider 7 can move with the top plate 3 and can always keep the slider 7 on the symmetrical plane of the bottom plate 1 and the top plate 3, so that the positioning of the pipeline axis can be completed directly. At the same time, the diameter of the pipeline can be determined according to the extended length of the first telescopic member 2. At this time, the rotating shaft 10 and the rotating tube 17 are coaxially distributed with the pipeline, thereby ensuring that the subsequent scraper 13 can completely contact the inner wall of the pipeline, achieving comprehensive cleaning of the inner wall of the pipeline and improving the cleaning effect. Afterwards, the second telescopic member 11 drives the scraper 13 to move until the scraper 13 contacts the inner wall of the pipe, and then the bottom plate 1 is moved in the pipe by the roller 5, illuminated by the lighting lamp, and the distribution of impurities in the pipe is observed by the camera. When cleaning impurities, the impurities are located on the rotation trajectory of the scraper 13, and then the first rotating power member 18 and the second rotating power member 19 respectively drive the rotating shaft 10 and the rotating tube 17 to rotate synchronously. At this time, the two groups of scrapers 13 make circular motions to clean the impurities on the inner wall of the pipe, and the cleaned impurities fall down to the bottom of the pipe, and then the bottom plate 1 continues to move. When the lower end of the dust suction hose 30 moves above the impurities, the impurities can be sucked up by the exhaust fan 29, and finally the impurities enter the collection box 23 through the dust outlet pipe 33.

[0027] In an example of the present embodiment, the first rotating power member 18 and the second rotating power member 19 are respectively the first motor and the second motor, and of course they can also be other components that can output rotational power, such as hydraulic motors. The first motor and the second motor respectively drive the rotating shaft 10 and the rotating tube 17 to rotate. The first telescopic member 2 and the second telescopic member 11 are respectively the first electric telescopic rod and the second electric telescopic rod, and of course they can also be other components that can actively change the length, such as hydraulic cylinders. The top plate 3 is driven up and down by the first electric telescopic rod, and the scraper 13 is driven to move by the second electric telescopic rod.

[0028] like Figure 1-Figure 4 As shown, a pipe cleaning robot for pipeline construction provided by the present invention is provided. A temporary storage box 12 is fixedly installed at the output end of the second telescopic member 11, and the opening of the temporary storage box 12 faces away from the second telescopic member 11. A scraper 13 is fixedly installed at the opening of the temporary storage box 12. Both ends of the scraper 13 are provided with a shielding protrusion structure connected to the temporary storage box 12. The scraper 13 and the end face of the temporary storage box 12 are provided with an angle, and the installation positions and angle directions of the two groups of scrapers 13 on the temporary storage box 12 are opposite.

[0029] Specifically, a baffle 14 is slidably mounted on the side wall of the temporary storage box 12. The baffle 14 is located at the opening of the temporary storage box 12. A first permanent magnet 15 is fixedly mounted on one end of the baffle 14 located inside the temporary storage box 12. The first permanent magnet 15 cooperates with an electromagnet 16 fixedly mounted on the side of the baffle 14.

[0030] In actual application of this embodiment, the two groups of scrapers 13 use the vertical plane passing through the axis of the pipeline as the dividing line to clean half of the inner wall of the pipeline respectively. In the initial state, the two groups of temporary storage boxes 12 are symmetrically distributed at the bottom of the pipeline and the rotation directions of the two groups of scrapers 13 are opposite. When the scrapers 13 contact the inner wall of the pipeline to clean impurities, the angle between the scrapers 13 and the end faces of the temporary storage boxes 12 is toward the front side of the rotation direction of the scrapers 13. When the scrapers 13 rotate around the inside of the pipeline, the impurities on the inner wall of the pipeline are scraped off by the scrapers 13. The scraped impurities will fall onto the scrapers 13 under the action of gravity, and the convex surfaces on both sides of the scrapers 13 will be removed. The shielding structure reduces the probability of impurities falling, and then the impurities follow the scraper 13 into the temporary storage box 12. When the scraper 13 rotates to the top of the inner wall of the pipe, the vertical downward projection of the contact position between the scraper 13 and the inner wall of the pipe exceeds the opening area of ​​the temporary storage box 12. At this time, part of the impurities scraped by the scraper 13 will fall directly to the bottom of the pipe. The temporary storage box 12 collects and stores a large amount of impurities scraped from the inner wall of the pipe in time, reducing the number of impurities falling to the bottom of the pipe, thereby avoiding the dispersion of impurities after collision, which is conducive to the subsequent cleaning of impurities and further improves the dust removal effect in the pipe. When the scraper 13 moves upward, the side magnetic poles of the electromagnet 16 and the first permanent magnet 15 are close to each other, so that the baffle 14 is in an open state under the action of magnetic force, and impurities can enter the temporary storage box 12. When the scraper 13 moves downward, the side magnetic poles of the electromagnet 16 and the first permanent magnet 15 are close to each other. At this time, the baffle 14 is in a closed state to prevent the impurities in the temporary storage box 12 from falling downward; When the two groups of scrapers 13 move to the top of the pipe and contact, the scrapers 13 stop moving. At this time, the first group of second telescopic members 11 contract to drive the temporary storage box 12 to move, so that the first group of scrapers 13 are away from the inner wall of the pipe and leave space for the second group of temporary storage boxes 12 to pass through. Then the second group of scrapers 13 continue to move and stop when they move to the position of the dividing line below the pipe. When the second group of scrapers 13 cross the dividing line above the pipe, the first group of scrapers 13 resets and continues to contact the inner wall of the pipe. Then the first group of scrapers 13 continues to rotate to the position of the dividing line below the pipe and stops. At this time, the area between the two groups of scrapers 13 in the initial state of the inner wall of the pipe is also cleaned, and the scraped impurities will directly slide down to the bottom of the pipe, so that the two groups of scrapers 13 can fully clean the inner wall of the pipe. The first group of scrapers 13 can be the scrapers 13 on the rotating shaft 10 or the scrapers 13 on the rotating tube 17. When the two groups of scrapers 13 are in contact with the bottom of the pipe, the impurities on the bottom of the pipe will be scooped up by the two groups of scrapers 13 and remain on the two groups of scrapers 13. Then the second telescopic member 11 contracts, and the shaft 10 and the rotating tube 17 rotate in coordination to ensure that the ends of the two groups of scrapers 13 are always in contact and move upward a set distance. Then the collecting box 23 moves to the bottom of the scrapers 13. At this time, the shaft 10 and the rotating tube 17 rotate in the opposite direction to separate the two groups of scrapers 13. At this time, the impurities on the scrapers 13 can fall downward into the collecting box 23. At the same time, the side magnetic poles of the electromagnet 16 and the first permanent magnet 15 that are close to each other become the same, so that the baffle 14 is opened and temporarily closed. The impurities in the storage box 12 fall into the collection box 23 synchronously. After the impurities are collected, the collection box 23 is reset. Then the first group of scrapers 13 moves to contact the inner wall of the pipe. Then the two groups of scrapers 13 continue to rotate to the initial state. When the second group of scrapers 13 passes over the first group of temporary storage boxes 12, the second group of scrapers 13 moves and contacts the inner wall of the pipe. At this time, the two groups of scrapers 13 return to the initial state. The two groups of scrapers 13 can be used to clamp and collect the impurities accumulated at the bottom of the pipe to avoid large particles of impurities remaining at the bottom of the pipe. The subsequent residual dust impurities can be sucked and collected by the exhaust fan 29, thereby further improving the effect of cleaning impurities in the pipe.

[0031] like Figure 1-Figure 6As shown, a pipe cleaning robot for pipeline construction provided by the present invention is provided. Two groups of parallel distributed brackets 22 are fixedly installed on the surface of the bottom plate 1 away from the top plate 3. The brackets 22 are L-shaped structures and the collection box 23 is slidably installed on the brackets 22. A third telescopic member 24 is fixedly installed on the surface of the bottom plate 1 away from the top plate 3. A second permanent magnet 25 is fixedly installed on the output end of the third telescopic member 24. The second permanent magnet 25 is used in conjunction with a connecting iron plate 26 fixedly installed on the side of the collection box 23.

[0032] Specifically, a telescopic rod 27 is fixedly installed on the surface of the bottom plate 1 away from the top plate 3, and a support plate 28 is fixedly installed on one end of the telescopic rod 27 away from the bottom plate 1. A vertical pipe 31 is fixedly installed on the support plate 28. The vertical pipe 31 and the rotating shaft 10 are distributed in the same vertical plane. The vertical pipe 31 is connected to the dust suction hose 30. A ball 32 is rotatably installed on the vertical pipe 31, and the end surface of the vertical pipe 31 away from the bottom plate 1 is higher than the bottom surface of the ball 32.

[0033] Specifically, a connecting tube 34 is rotatably mounted on one end of the dust outlet pipe 33 away from the exhaust fan 29 , and the connecting tube 34 is threadedly connected to the collection box 23 .

[0034] In actual application of this embodiment, the collection box 23 is installed on the bracket 22, so that the connecting iron plate 26 contacts the second permanent magnet 25, and then the dust outlet pipe 33 is connected to the collection box 23 through the connecting tube 34. When the bottom plate 1 is placed in the pipeline, the telescopic rod 27 is extended under the action of gravity, so that the ball 32 contacts the bottom of the pipeline, and the lower end of the vertical pipe 31 can be close to the bottom surface of the pipeline. During cleaning, impurities at the bottom of the pipeline are collected by the scraper 13 and reset in the collection box 23, then the exhaust fan 29 is turned on, the exhaust fan 29 draws air through the dust suction hose 30 and the vertical pipe 31, and transports the air to the collection box 23 through the dust outlet pipe 33. The collection box 23 is provided with a filter for air to flow out, and then the bottom plate 1 moves forward to collect and clean the powdery impurities remaining at the bottom of the pipeline.

[0035] In an example of the present invention, the third telescopic member 24 is a third electric telescopic rod, and of course, it can also be other components that can actively change the length, such as a hydraulic cylinder, and the collection box 23 is driven to move by the third electric telescopic rod.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.

[0037] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
