Description

Technical Field

[0001] This invention relates to the field of steel pipe cleaning, and in particular to an automatic cleaning device for steel pipes. Background Technology

[0002] Stainless steel pipe is a hollow, long strip of steel. The steel pipe is generally drawn from a thicker steel pipe to a thinner steel pipe. Special drawing oil is required during the drawing process. After drawing, the oil must be removed. The oil has a significant impact on the steel pipe, so the steel pipe needs to be degreased.

[0003] Currently, the steel pipe cleaning process typically uses manual cleaning methods such as tank immersion, pickling, and air injection to remove oil stains from the steel pipes. This method is outdated, ineffective, requires a lot of manpower, and is labor-intensive.

[0004] The inner walls of slender steel pipes are particularly difficult to clean. Manual cleaning methods such as soaking, pickling, and aeration cannot thoroughly clean the pipes and have long cleaning cycles, which affects the cleaning effect and efficiency and needs to be improved. Summary of the Invention

[0037] The present invention will be further described in detail below with reference to the accompanying drawings.

[0038] like Figure 1 As shown, an automatic cleaning device for steel pipes includes multiple transmission mechanisms 1, a feeding mechanism 2, an outer wall cleaning mechanism 3, a bearing mechanism 4, a pouring mechanism 5, an inner wall brushing mechanism 6, and a unloading mechanism 7.

[0039] like Figure 1 As shown, multiple transmission mechanisms 1 are arranged at intervals on the ground and are used to support and transport steel pipes. A feeding mechanism 2 is used to feed the steel pipes and transfer them to the preceding transmission mechanism 1. An outer wall cleaning mechanism 3 is located to one side of the last transmission mechanism 1 and is used to clean the outer wall of the steel pipes.

[0040] like Figure 1 , Figure 2 As shown, the bearing mechanism 4 includes a first bearing component 41 and a second bearing component 42. The first bearing component 41 and the second bearing component 42 are arranged side by side and are used to bear the steel pipe. The first bearing component 41 is located behind the rearmost transmission mechanism 1, and the second bearing component 42 is lower than the first bearing component 41.

[0041] like Figure 2As shown, both the first bearing component 41 and the second bearing component 42 include multiple bearing seats 43 and bearing wheels 44. The bearing seats 43 are vertically and spaced apart on the ground. The bearing wheels 44 are in pairs and rotatably connected to the bearing seats 43, and are used to support the steel pipe.

[0042] like Figure 2 As shown, the unloading mechanism 5 is used to guide the steel pipe from the first bearing assembly 41 to the second bearing assembly 42. The inner wall washing mechanism 6 is located at both ends of the second bearing assembly and is used to clean the inner wall of the steel pipe. The unloading mechanism 7 is used to unload the cleaned steel pipe from the bearing assembly 4.

[0043] When cleaning the steel pipes, the feeding mechanism 2 transports the steel pipes one by one to the transmission mechanism 1, and the transmission mechanism 1 transports the steel pipes into the outer wall cleaning mechanism 3, so as to realize the automatic cleaning of the outer wall of the steel pipes.

[0044] The cleaned steel pipes are then transferred to the first bearing assembly 41 on the bearing mechanism 4, and then the unloading mechanism 5 guides the steel pipes from the first bearing assembly 41 onto the second bearing assembly 42. The inner wall cleaning mechanism 6 then cleans the inner wall of the steel pipes on the second bearing assembly 42. After cleaning, the unloading mechanism 7 removes the cleaned steel pipes from the second bearing assembly 42 and continues to transport them to the next process, achieving continuous production.

[0045] Therefore, by setting up highly automated cleaning equipment, the automatic feeding, automatic transmission, automatic cleaning of the outer wall, automatic brushing of the inner wall, and automatic unloading of steel pipes can be achieved, replacing traditional manual cleaning, saving labor, shortening cleaning time, and improving cleaning effect and efficiency.

[0046] like Figure 1 , Figure 3 , Figure 4 As shown, the transmission mechanism 1 includes a transmission base 11, a transmission platform 12, an active transmission wheel 13, and a driven transmission wheel 14. The transmission base 11 is vertically mounted on the ground, and its centerline has an angle of 10°-20° with the direction of travel of the steel pipe.

[0047] like Figure 1 , Figure 3 , Figure 4 As shown, the transmission platform 12 is horizontally mounted on the transmission base 11. One end of the transmission platform 12 is rotatably connected to the transmission base 11. A cylinder 15 is rotatably connected to the transmission base 11, and the piston rod of the cylinder 15 is rotatably connected to the other end of the transmission platform 12.

[0048] like Figure 1 , Figure 3 , Figure 4As shown, the active transmission wheel 13 and the driven transmission wheel 14 are arranged side by side and rotate on both sides of the transmission table 12. The outer wall of the active transmission wheel 13 is tapered towards the direction of travel. The outer wall of the driven transmission wheel 14 is tapered towards the direction of travel, so as to automatically push the steel pipe forward during rotation.

[0049] When the steel pipe needs to be transported, it is positioned between the driving transmission wheel 13 and the driven transmission wheel 14. The driving transmission wheel 13 rotates, and the driven transmission wheel 14 rotates synchronously with the steel pipe. Since the driving transmission wheel 13 and the driven transmission wheel 14 are configured with one end larger than the other, and the directions of the larger and smaller ends are opposite, and there is an angle between the entire transmission mechanism 1 and the transmission direction of the steel pipe, the steel pipe can be controlled to rotate and move forward simultaneously during the rotation of the driving transmission wheel 13 and the driven transmission wheel 14, thus achieving stable transmission of the steel pipe.

[0050] Since the transmission platform 12 is rotatably connected to the transmission base 11, the cylinder 15 can be used to control the transmission platform 12 to tilt during actual operation, thereby adjusting the angle of the transmission platform 12 to adapt to steel pipes of different thicknesses. Furthermore, the tilt angle of the transmission platform 12 can also adjust the transmission rate of the steel pipe to meet different transmission requirements.

[0051] like Figure 3 , Figure 5 As shown, the feeding mechanism 2 includes multiple feeding racks 21, which are arranged side by side and extend downward at an incline to the position of the transmission mechanism 1. A feeding stop bar 22 is provided at the lowest end of the feeding rack 21.

[0052] like Figure 3 , Figure 5 As shown, a pair of feeding supports 23 are provided on the side of the feeding rack 21 near the conveying mechanism 1, which are located between two adjacent conveying mechanisms 1 respectively. A feeding plate 24 is rotatably connected to the feeding support 23.

[0053] like Figure 3 , Figure 5 As shown, the feeding plate 24 is L-shaped, and after flipping, the side that contacts the steel pipe is inclined downward. The feeding plate 24 is used to lift the steel pipe on the feeding rack 21 after flipping, and make the steel pipe automatically roll down to the top of the transmission mechanism 1.

[0054] When it is necessary to feed steel pipes, the steel pipes are transported one by one to the feeding rack 21, so that the steel pipes are laid horizontally on multiple feeding racks 21. At the same time, the steel pipes automatically roll down to the lowest position of the feeding rack 21 and are blocked by the feeding stop bar 22, thus achieving the positioning of the steel pipes.

[0055] Then, the hydraulic cylinder 358 is used to control the rotation of the feeding plate 24. At this time, the feeding plate 24 flips from a horizontal position to a vertical position, and the feeding plate 24 lifts up the steel pipe. Since the feeding plate 24 is inclined, the steel pipe will automatically roll down to the lowest position of the feeding plate 24 and be blocked by the bending position. At this time, the steel pipe is directly above the transmission mechanism 1.

[0056] Then, the feeding plate 24 is controlled to rotate in the opposite direction. At this time, the feeding plate 24 flips from a vertical position to a horizontal position, and the feeding plate 24 gradually lowers the steel pipe, so that the steel pipe is accurately placed on the transmission mechanism 1, thereby realizing the automatic feeding of the steel pipe.

[0057] like Figure 6 As shown, the external wall cleaning mechanism 3 includes a cleaning seat 31, a cleaning pool 32, a cleaning hood 33, a cleaning pipe 34, and a cleaning support 35. The cleaning seat 31 is set on the ground, the cleaning pool 32 is embedded in the cleaning seat 31, and the cleaning hood 33 is fastened to the cleaning seat 31, covering the cleaning pool 32 and allowing the steel pipe to pass through. One end of the cleaning pipe 34 is connected to the cleaning pool 32, and the other end is located on top of the cleaning hood 33.

[0058] like Figure 6 As shown, the cleaning support 35 is located at both ends of the cleaning cover 33, and is used to support and clean the outer wall of the steel pipe, respectively.

[0059] like Figure 6 As shown, a rinsing seat 36 is provided behind the cleaning seat 31. The rinsing seat 36 is fitted with a rinsing pool 37, and a rinsing cover 38 covering the rinsing pool 37 is fastened to the rinsing seat 36. A rinsing pipe 39 is connected to the rinsing pool 37, and the rinsing pipe 39 is connected to the top of the rinsing cover 38.

[0060] When cleaning the outer wall of the steel pipe, the steel pipe enters the cleaning hood 33 and is held by the cleaning support 35. At this time, the cleaning pipe 34 sprays the cleaning liquid in the cleaning tank 32 onto the outer wall of the steel pipe, and works in conjunction with the cleaning support 35 to achieve the cleaning of the outer wall of the steel pipe. At the same time, the cleaning liquid can be recycled and reused to reduce waste.

[0061] The steel pipe then enters the rinsing hood 38, where the rinsing pipe 39 sprays the rinsing fluid from the rinsing pool 37 onto the outer wall of the steel pipe, thus rinsing the outer wall and ensuring its cleanliness. Simultaneously, the rinsing fluid can be recycled and reused, reducing waste.

[0062] like Figure 6 As shown, the cleaning support 35 includes a pair of lower supports 351, a lower wheel frame 352, a pair of lower cleaning wheels 353, an upper support 354, an upper wheel frame 355, and an upper cleaning wheel 356.

[0063] like Figure 6As shown, a pair of lower seats 351 are distributed on both sides of the cleaning hood 33, the lower wheel frame 352 is set on the lower seat 351 and extends into the cleaning hood 33, the lower cleaning wheel 353 is rotatably connected to the lower wheel frame 352 and is located inside the cleaning hood 33, and is used to support the steel pipe.

[0064] like Figure 6 As shown, the upper seat 354 is mounted on the cleaning hood 33, the upper wheel frame 355 is mounted on the upper seat 354 and extends into the cleaning hood 33, and the upper cleaning wheel 356 is rotatably connected to the upper wheel frame 355 and is located inside the cleaning hood 33, and is used to press the steel pipe.

[0065] like Figure 6 As shown, the lower wheel frame 352 is rotatably connected to the lower seat 351 at the middle position. A guide rod 357 that passes through the wheel frame is provided at the opposite end of the lower seat 351. A spring 3571 located above the lower wheel frame 352 is sleeved on the guide rod 357.

[0066] like Figure 6 As shown, the upper wheel frame 355 is rotatably connected to the upper seat 354 at the middle position, and a hydraulic cylinder 358 is rotatably connected to the cleaning seat 31. The piston rod of the hydraulic cylinder 358 is rotatably connected to the end of the upper wheel frame 355.

[0067] When cleaning the outer wall of the steel pipe, as the steel pipe enters, it presses the lower roller frame 352 and the lower cleaning roller 353 downwards. At this time, the lower roller frame 352 compresses the spring 3571. Furthermore, when the steel pipe detaches from the lower roller frame 352, the spring force of the spring 3571 causes the lower roller frame 352 and the lower cleaning roller 353 to automatically rotate back to their initial positions. This allows the lower roller frame 352 and the lower cleaning roller 353 to automatically adapt to steel pipes of different specifications and consistently press against the steel pipe surface, achieving stable cleaning.

[0068] Meanwhile, when the steel pipe enters, the upper wheel frame 355 and the upper cleaning wheel 356 are first controlled by the hydraulic cylinder 358 to rotate upward. After the steel pipe enters, the upper wheel frame 355 and the upper cleaning wheel 356 are then controlled to rotate downward, so that the upper cleaning wheel 356 presses against the surface of the steel pipe. This allows the upper wheel frame 355 and the upper cleaning wheel 356 to automatically adapt to steel pipes of different specifications and always press against the surface of the steel pipe, achieving stable cleaning.

[0069] like Figure 6 As shown, a pair of lower seats 351 are laterally slidably connected to the cleaning seat 31, and a screw 359 is horizontally threaded onto the cleaning seat 31. The screw 359 is rotatably connected to the end of the lower seats 351. Therefore, the distance between the pair of lower seats 351 can be controlled according to the diameter of the steel pipe and actual needs to meet different working requirements.

[0070] like Figure 6As shown, the material pouring mechanism 5 includes multiple material pouring racks 51, which are arranged side by side between the first bearing component 41 and the second bearing component 42, with one end closer to the first bearing component 41 being higher than the other end. A material pouring stop bar 52 is provided at the lowest end of the material pouring rack 51.

[0071] like Figure 6 As shown, both sides of the pouring frame 51 are provided with pouring supports 53, which are located between two adjacent bearing seats 43. A pouring plate 54 is rotatably connected to the pouring support 53. The pouring plate 54 is L-shaped, and after being flipped, the side that contacts the steel pipe is inclined downward.

[0072] like Figure 6 As shown, one of the tipping plates 54 is used to flip over and lift the steel pipe on the first bearing assembly 41, causing the steel pipe to automatically roll down onto the tipping frame 51. The other tipping plate 54 is used to flip over and lift the steel pipe at the lower end of the tipping frame 51, causing the steel pipe to automatically roll down onto the second bearing assembly 42.

[0073] After the steel pipe is transferred to the first bearing assembly 41, the hydraulic cylinder 358 located near the first bearing assembly 41 controls the tilting plate 54 located near the first bearing assembly 41 to rotate. At this time, the tilting plate 54 flips from a horizontal position to a vertical position, and simultaneously lifts the steel pipe. Since the tilting plate 54 is inclined, the steel pipe will automatically roll down to the lowest position of the tilting plate 54 and be blocked by the bend. At this time, the steel pipe is directly above the upper part of the tilting frame 51.

[0074] Then, the pouring plate 54 is controlled to rotate in the opposite direction. At this time, the pouring plate 54 flips from a vertical position to a horizontal position. At the same time, the pouring plate 54 gradually lowers the steel pipe, so that the steel pipe is accurately placed at the upper position of the pouring frame 51. Then the steel pipe rolls down along the pouring frame 51. When the steel pipe automatically rolls down to the lowest position of the pouring frame 51, it is blocked by the pouring stop bar 52, thus achieving the positioning of the steel pipe.

[0075] Subsequently, the hydraulic cylinder 358 located near the second support component 42 controls the tilting plate 54 located near the second support component 42 to rotate. At this time, the tilting plate 54 flips from a horizontal position to a vertical position, and simultaneously lifts the steel pipe. Since the tilting plate 54 is inclined, the steel pipe will automatically roll down to the lowest position of the tilting plate 54 and be blocked by the bend. At this time, the steel pipe is directly above the upper part of the second support component 42.

[0076] Then, the unloading plate 54 is controlled to rotate in the opposite direction. At this time, the unloading plate 54 flips from a vertical position to a horizontal position. Simultaneously, the unloading plate 54 gradually lowers the steel pipe, so that the steel pipe is accurately placed on the second bearing component 42, realizing the automatic unloading of the steel pipe.

[0077] like Figure 7 As shown, the inner wall scrubbing mechanism 6 includes a scrubbing seat 61, a scrubbing pipe 62, a scrubbing head 63, a traveling trolley 64, and a sewage tank 65. The scrubbing seat 61 is distributed at both ends of the second supporting component 42. The scrubbing pipe 62 is horizontally slidably connected to the scrubbing seat 61 and is used to insert into both ends of the steel pipe. The scrubbing head 63 is located at the end of the scrubbing pipe 62 and is used to press against the inner wall of the steel pipe.

[0078] like Figure 7 As shown, the traveling vehicle 64 is slidably connected to the scrubbing seat 61 and is used to control the horizontal sliding of the scrubbing pipe 62. The sewage tank 65 is located between the scrubbing seat 61 and the second bearing component 42, and is located below the position of the steel pipe opening.

[0079] When it is necessary to clean the inner wall of the steel pipe, the walking vehicle 64 controls the brush pipe 62 and the brush head 63 to slide synchronously and insert the end of the brush pipe 62 into the steel pipe. At the same time, the second bearing component 42 controls the rotation of the steel pipe and the walking vehicle 64 controls the brush pipe 62 and the brush head 63 to move slowly.

[0080] At this point, the cleaning solution will flow into the steel pipe along the scrubbing pipe 62, and work with the scrubbing head 63 to scrub the inner wall of the steel pipe. The combination of scrubbing and rinsing ensures the cleaning effect of the inner wall of the steel pipe and improves its cleanliness. Finally, the wastewater will be collected in the wastewater tank 65 to achieve stable wastewater recovery. After recovery, an oil-water separation mechanism can be added to the wastewater tank 65 to achieve the reuse of the cleaning solution.

[0081] Since the two ends of the steel pipe are inserted into the scrubbing pipe 62 at the same time, when cleaning the inner wall, one of the scrubbing pipes 62 can be retracted when both scrubbing pipes 62 have traveled to the middle of the steel pipe, while the other scrubbing pipe 62 continues to slide forward, thus ensuring that the inner wall of the steel pipe is cleaned in all directions.

[0082] like Figure 8 As shown, the unloading mechanism 7 includes a transport track 71, a transport roller 72, and an unloading support 73. The transport track 71 is horizontally arranged beside the second bearing component 42, and the transport roller 72 is horizontally rotatably connected to the transport track 71. Both ends of the transport roller 72 are provided with limiting rods 74 for clamping steel pipes.

[0083] like Figure 8 As shown, the unloading support 73 is located between two adjacent bearing seats 43. An unloading plate 75 is rotatably connected to the unloading support 73. The unloading plate 75 is L-shaped, and after being flipped, the side that contacts the steel pipe is inclined downward. The unloading plate 75 is used to lift the steel pipe on the second bearing assembly 42 after being flipped, and to make the steel pipe automatically roll down to directly above the conveyor roller 72.

[0084] When the cleaned steel pipes need to be unloaded, the hydraulic cylinder 358 controls the unloading plate 75 to rotate. At this time, the unloading plate 75 flips from a horizontal position to a vertical position, and simultaneously lifts the steel pipe. Since the unloading plate 75 is inclined, the steel pipe will automatically roll down to the lowest position of the unloading plate 75 and be blocked by the bend. At this time, the steel pipe is directly above the conveyor roller 72.

[0085] Then, the unloading plate 75 is controlled to rotate in the opposite direction. At this time, the unloading plate 75 flips from a vertical position to a horizontal position, and the unloading plate 75 gradually lowers the steel pipe, so that the steel pipe is accurately placed on the transport roller 72 and positioned between the limit rods 74 at both ends of the transport roller 72. Finally, the transport roller 72 is controlled to rotate, so that the cleaned steel pipe can be transferred to the next step or process.

[0086] The specific embodiments are merely illustrative of the present invention and are not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
