Description

Technical Field

[0001] This invention relates to the field of pipe manufacturing and processing technology, specifically to a device and method for cleaning dust from the surface of pipes after manufacturing. Background Technology

[0002] In the pipe manufacturing industry, after pipe production, a large amount of dust often adheres to their surface. This dust comes from multiple sources. On one hand, suspended particulate matter already present in the production workshop gradually settles and adheres to the pipe surface during the manufacturing process. On the other hand, processes such as cutting, grinding, and welding generate metal shavings, plastic particles, and other impurities, which also mix with dust and adhere to the pipe surface. If the dust on the pipe surface is not cleaned promptly, it can cause many serious problems. Traditional external cleaning and tumbling of pipes poses significant safety risks, and the lack of temporary protection during external pipe cleaning easily leads to re-contamination, affecting the cleaning effect. Furthermore, manual cleaning is labor-intensive and has a low safety factor. Cleaning the dust on the pipe surface cannot be limited to the outer surface; dust on the inner wall of the pipe often has a more significant impact on its later development. Current pipe manufacturing processes often involve relatively simple cleaning of the inner wall, failing to thoroughly clean it. Summary of the Invention

[0022] This invention also discloses a method for using a device for cleaning surface dust after pipeline production, comprising the following steps: S1: First, place one end of the pipe on the rollers of the workbench. The rollers support the pipe. Through the drive mechanism, the drive wheel can be rotated, which in turn rotates the pipe. Since the drive wheel is set at a 20° angle, the pipe can rotate itself while moving forward. S2: Driven by the drive wheel, the pipe enters the water washing assembly. The water pipe is connected to an external water source in advance and pressurized by an external water pump, so that the nozzle of the water washing assembly sprays out cleaning water. As the pipe moves forward and rotates, it can thoroughly clean the outer surface of the pipe. S3: After the outer wall of the pipe is wetted with clean water, it enters the cleaning component, which cleans the outer surface of the pipe. S4: Next, the pipe will enter the drying unit, which will clean the residual moisture on the outer surface of the pipe, allowing the pipe to dehydrate quickly. S5: Then, the inner wall cleaning component will enter the pipe and drive the track to fit against the inner wall of the pipe. By driving the track, the entire cleaning robot will move and connect to the external water source, spraying cleaning water through nozzle two to clean the inner wall of the pipe.

[0023] The beneficial effects of this invention are as follows: This invention optimizes the overall cleaning environment by first wetting the pipe to remove surface dust. Directly cleaning dust can cause dust to fly around, but wetting effectively solves this problem and makes the cleaning process more convenient. Finally, there is also a device for cleaning the inner wall of the pipe, which can thoroughly clean all parts of the pipe, achieving efficient cleaning and improving overall work efficiency.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] In the description of the invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0037] Please see the appendix Figure 1-9This invention discloses a device for cleaning surface dust after pipeline production, including a workbench 1, a groove 2 inside the workbench 1, a drain pipe 3 on the side wall of the groove 2, a boss 4 fixedly installed on the front half of the groove 2, a guide forward component on the workbench 1 corresponding to the boss 4, a water washing component 6, a cleaning component 7, a drying component 8 and an inner wall cleaning component 9 arranged sequentially from front to back on the workbench 1, and an auxiliary guide component 10 on the workbench 1 corresponding to the water washing component 6.

[0038] The guiding forward assembly includes two rows of support columns 501 evenly arranged on the boss 4. The two rows of support columns 501 are symmetrically distributed on the upper surface of the boss about its front and rear axes. Each support column 501 is rotatably connected to a roller 502. Several support rods 503 are evenly fixedly installed in the groove 2 away from the washing assembly 6. The support rods 503 are also arranged in two symmetrical rows. From the front end to the rear end of the groove, the length of the support rods 503 increases evenly. Each support rod 503 is rotatably connected to a roller 504. The two rows of rollers 502 and rollers 504 are arranged in a V-shape. Because the rollers 502 and rollers 504 are arranged in a V-shape, they can meet the support processing of pipes of various diameters. Connecting brackets 505 are inserted into the front end of the worktable 1 and the axis of the boss 4. A spring 506 is fixedly installed on the connecting bracket 505, and a motor 507 is fixedly installed on the connecting bracket 505. A drive wheel 508 is fixedly installed on the output end of the motor 507. The other end of the drive wheel 508 is rotatably connected to the connecting bracket 505. The angle between the drive wheel 508 and the axis of the worktable 1 is 20°. When a pipe is pressed on the drive wheel 508, the elastic force of the spring 506 can make the drive wheel 508 contact the pipe more tightly. Precise textures are also set on the drive wheel 508 to further increase the overall friction. By rotating the angled drive wheel 508, the pipe can be driven forward and rotate.

[0039] In one embodiment, the water washing assembly 6 includes a bracket 601 fixedly mounted on a workbench 1. The upper end of the bracket 601 is arc-shaped, and the whole is inverted U-shaped. A plurality of nozzles 602 are evenly provided on the upper end of the bracket 601. A water pipe 603 is provided on one side of the bracket 601. The water pipe 603 is interconnected with the nozzles 602 through the bracket 601. The nozzles 602 are arranged in an arc shape, which has a wider spraying area than the pipe, and can better wet the outer surface of the pipe with cleaning water.

[0040] In one embodiment: the cleaning component 7 includes a second bracket 701 located on the workbench 1. A connecting rod 702 is symmetrically inserted into the upper end of the second bracket 701. A second spring 703 is fixedly installed on the first connecting rod 702 and is fixedly connected to the second bracket 701. A first roller brush 704 is rotatably connected between the first connecting rod 702 and the second connecting rod 704. A second connecting rod 705 is symmetrically inserted into the second bracket 701 about the first roller brush 704. A third spring 706 is fixedly installed on the second connecting rod 705 and is fixedly connected to the second bracket 701. The second connecting rod 705 is rotatably connected to the second connecting rod 705. A second roller brush 707 is attached. A sensor box 708 is fixedly installed on the side of the connecting rod 702 and the second connecting rod 705 near the support 601. A sensor wheel 709 is rotatably connected to the sensor box 708. A ball bearing 7010 is evenly rotatably connected to the sensor wheel 709. The sensor wheel 709 can contact the end of the pipe in advance, so that the first roller brush 704 and the second roller brush 707 are compressed. At the same time, the elastic force of the second spring 703 and the third spring 706 can make the first roller brush 704 and the second roller brush 707 fit tightly against the pipe. The ball bearing 7010 is designed to adapt to the rotation of the pipe.

[0041] In one embodiment, the air-drying assembly 8 includes a support 801 located on the workbench 1. A fan 802 is fixedly installed on the upper side of the support 801, and an air outlet 803 is fixedly installed on the lower side of the support 801. The fan 802 and the air outlet 803 are interconnected, and the opening of the air outlet 803 is duckbill-shaped. The duckbill-shaped air outlet 803 design can accelerate the overall airflow and make the drying effect better.

[0042] In one embodiment: the inner wall cleaning component 9 includes a cleaning robot located on the boss 4. The inner wall cleaning component 9 includes a second water pipe 901 connected to the outside. A base 902 is provided on the second water pipe 901. A support pipe 903 is fixedly installed on the base 902. A waterproof camera 904 is provided at the end of the support pipe 903 away from the base 902. The waterproof camera 904 allows workers to easily observe the clear internal situation through an external screen. Spray nozzles 905 are symmetrically provided on the support pipe 903. The second water pipe 901 is interconnected with the second spray nozzles 905 through the support pipe 903. Three sets of linkage mechanisms are uniformly hinged circumferentially on the outer side of the support pipe 903. Each set of linkage mechanisms includes two first linkages 906 and two second linkages 907. The first linkages 906 and the second linkages 907 are parallel to each other in a plane extending along the axial direction of the support pipe 903. The two first linkages 906 or the two second linkages 907 are parallel to each other in a plane intersecting with the axial direction of the support pipe 903. The other ends of connecting rod 906 and connecting rod 907 in the same group are hinged to the drive track 908, that is, the two connecting rods 906 or the two connecting rods 907 are symmetrically arranged on both sides of the drive track 908. The two sides of the drive track 908 are also symmetrically hinged to telescopic rods 909. The hinge point between the telescopic rod 909 and the drive track 908 is the first hinge point, the hinge point between connecting rod 906 and the drive track is the second hinge point, and the hinge point between connecting rod 907 and the drive track is the third hinge point. The first hinge point is located between the second hinge point and the third hinge point. A spring 9010 is installed on the telescopic rod 909. An adjusting ring 9011 is slidably connected to the outside of the support tube 903. The other end of the telescopic rod 909 is hinged to the adjusting ring 9011. A limit ring 9012 is installed on the outside of the support tube 903. Several limit rods 9013 are evenly fixedly installed on the circumference of the limit ring 9012. The axis of the limit rods 9013 is parallel to the axis of the support tube 903. The adjusting ring 9011 is slidably installed on the outside of the limit rods 9013. The limit rods 9013 ensure that the entire track mechanism moves axially and prevents deviation. The adjusting ring 9011 ensures that the telescopic rods 909 are evenly spaced. Multiple sets of drive tracks travel inside the pipe and penetrate into the pipe to clean the inner wall of the pipe. The inner wall cleaning component 9 of this structure can adapt to cleaning work within a certain pipe diameter range.

[0043] In the above embodiments, the linkage mechanism and the drive track 908 connected thereto can be two or four sets, as long as they are evenly distributed circumferentially on the outer side of the support tube 903.

[0044] In one embodiment: the auxiliary guiding component 10 includes a slide rod 1001 symmetrically connected to a support 601, an L-shaped rod 1002 fixedly mounted on the slide rod 1001, a dual-axis motor 1003 fixedly mounted on the lower side of the worktable 1, a screw 1004 fixedly mounted on the output end of the dual-axis motor 1003, the screw 1004 being threadedly connected to the L-shaped rod 1002, and a connecting box 1005 fixedly mounted on the other end of the slide rod 1001, with a plurality of rollers 1006 evenly rotatably connected inside the connecting box 1005; by controlling the mutual approach of the rollers 1006 on both sides, the moving pipeline can have a more stable operating environment, reducing the probability of instability when only rollers 502 and 504 provide support.

[0045] The general working process of this invention is as follows: The pipe is placed on the workbench 1 and moved by the guide component; it passes through the water washing component 6, the cleaning component 7, the air drying component 8 and the inner wall cleaning component 9 in sequence to thoroughly clean the inner and outer surfaces of the pipe, making it cleaner overall.

[0046] The process specifically includes the following steps: S1: First, place one end of the pipe on the roller 502 on the workbench 1. Since the roller 502 is arranged in a V-shape, it can support the pipe. At the same time, the pipe will press against the drive wheel 508 on the workbench 1. After the drive wheel 508 is pressed, it will compress the spring 506, so that the spring 506 exerts pressure on the drive wheel 508, so that the drive wheel 508 can effectively contact the surface of the pipe. By starting the motor 507, the drive wheel 508 can be driven to rotate, which in turn drives the pipe to rotate. Since the drive wheel 508 is set at a 20° angle, the pipe can rotate on its own while moving forward. S2: Driven by the drive wheel 508, the pipe will enter the support 601. When the pipe enters the support 601, the dual-axis motor 1003 needs to be controlled to work, driving the screw 1004 to rotate, so that the L-shaped rods 1002 on both sides move synchronously, so that the rollers 1006 on both sides can slightly approach the outer wall of the pipe, providing a good operating environment for the pipe; the water pipe 603 is connected to the external water source in advance, and pressurized by the external water pump, so that the nozzle 602 sprays out cleaning water. As the pipe moves forward and rotates, the outer surface of the pipe can be thoroughly cleaned. S3: After cleaning, the wastewater will flow into the groove 2 of the workbench 1 through the boss 4. The drain pipes 3 evenly arranged in the groove 2 can discharge the wastewater in a measured amount to ensure the hygiene of the working environment. S4: After the pipe is wetted with clean water, it enters the bracket 2 701. The induction wheel 709 can sense the outer diameter of the pipe in advance. Under the elastic force of spring 2 703 and spring 3 706, the roller brush 1 704 and roller brush 2 707 can fully adhere to the outer wall of the pipe. At the same time, the motors built into roller brush 1 704 and roller brush 2 707 work, causing roller brush 1 704 and roller brush 2 707 to rotate and clean the outer surface of the pipe. Since the pipe has a certain degree of rotation, the designed ball bearing 7010 can adapt well to the rotation of the pipe. S5: Next, the pipe will enter the support 3 801. The fan 802 inside the support 3 801 provides high-speed airflow. The airflow is compressed through the duckbill-shaped air outlet pipe 803 and obtains high-speed airflow to clean the residual moisture on the outer surface of the pipe, so that the pipe can be dehydrated quickly. S6: Then, the inner wall cleaning component 9 will enter the front end of the pipe and adjust the spacing of the drive track 908 through the first link 906, the second link 907 and the telescopic rod 909, so that the drive track 908 can effectively fit against the inner wall of the pipe. Driven by the drive track 908, the entire inner wall cleaning component 9 moves and connects to the external water source. The cleaning water is sprayed out through the second water pipe 901 and the second nozzle 905 to clean the inner wall of the pipe. The built-in waterproof camera 904 can capture the cleaning scene and check the cleaning status inside. S7: Finally, the pipe will slowly tilt up at one end under the support of the roller 504 on the support rod 503, so that the water in the pipe can be drained and flow into the groove 2. The worker can then remove the pipe.

[0047] The present invention and its embodiments have been described above. This description is not restrictive, and the specific embodiments shown are only one of the embodiments of the present invention. The actual structure is not limited to this. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the present invention, they should all fall within the protection scope of the present invention.
