Description

Technical Field

[0001] The present invention belongs to the technical field of stainless steel pipe production, and specifically relates to a stainless steel pipe production cleaning device. Background Art

[0002] Stainless steel pipes are a kind of hollow long circular steel, mainly widely used in industrial conveying pipelines such as petroleum, chemical industry, medical treatment, food, light industry, machinery instruments, etc., and mechanical structure components, etc. During the production process of stainless steel pipes, workers need to perform procedures such as steel coil slitting, pipe rolling forming, welding, weld heat treatment, hot rolling, cold processing, cleaning, etc. on the stainless steel pipes in sequence; among them, when performing the cleaning procedure, the stainless steel pipes to be cleaned need to be soaked in a chemical solution first, and the specific chemical solution is adjusted according to the different dirt on the surface of the stainless steel pipes to be removed. For example, when cleaning the lubricant or coolant used in procedures such as cold rolling, drawing, and cutting on the surface of the stainless steel pipes, it is necessary to soak them in a sodium hydroxide solution and then wash them with clean water. When cleaning the oxide layer after heat treatment (such as solution treatment) or welding on the surface of the stainless steel pipes, it is necessary to soak them in a mixed solution of nitric acid and hydrofluoric acid and then rinse them with clean water.

[0003] Currently, when cleaning stainless steel pipes, it is necessary to transfer the stainless steel pipes to a dedicated cleaning workshop, and then soak the stainless steel pipes in a container filled with a chemical solution in the workshop. After soaking for a period of time, take them out and transfer them to a bracket, and then workers rinse them with a water gun. When specifically rinsing the stainless steel pipes, the external cleaning of the stainless steel pipes is relatively convenient, and workers only need to aim at the external surface of the stainless steel pipes for rinsing. However, when cleaning the inside of the stainless steel pipes, it is necessary to aim the water gun at the pipe orifice of the stainless steel pipe, and then spray clean water into the inside of the stainless steel pipe through the pipe orifice of the stainless steel pipe, and the clean water rinses the inner wall of the stainless steel pipe. However, in the actual cleaning process, there is relatively firmly attached dirt on the inner wall of the stainless steel pipe, and it is difficult to effectively clean it only by rinsing with clean water.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figures 1 to 17 As shown, a stainless steel pipe production cleaning equipment according to an embodiment of the present invention comprises a pair of cleaning racks 1, a pair of soaking tanks 2 are symmetrically arranged on both sides of the cleaning rack 1, a support rack 3 is installed at the end of the cleaning rack 1, a plurality of fixed cylinders 4 are fixedly connected to the top of the support rack 3, a plug-in rod 42 is inserted into the interior of the fixed cylinder 4, a plurality of support components are fixedly connected to the surface of the plug-in rod 42, a support block 53 is fixed to the end of the support component away from the plug-in rod 42, a transmission gap 531 is provided at the top of the support block 53 located at the top, a driving wheel 532 is rotatably connected to the interior of the transmission gap 531, a driving groove is provided on the wheel surface of the driving wheel 532, a plurality of teeth are fixedly connected to the annular inner wall of the driving groove in an annular shape, a transmission chain 61 meshing with the teeth is sleeved in the driving groove, and a driving component is provided on the part of the transmission chain 61 located outside the transmission gap 531; The end of the fixed cylinder 4 away from the cleaning rack 1 is fixedly connected to a water spray head 41, an electromagnet 421 is fixedly connected to the interior of the fixed cylinder 4, the end of the plug rod 42 close to the cleaning rack 1 is rotatably connected to a rotating shaft 43, a plurality of water baffles 44 are fixedly connected to the annular circumference of the rotating shaft 43, and a plurality of connecting springs 45 are fixedly connected to the end of the rotating shaft 43 away from the plug rod 42 in an annular shape, and a sponge block 46 is fixedly connected to the end of the connecting spring 45 away from the rotating shaft 43; the number of cleaning racks 1 can be adjusted as needed; When actually cleaning the inner wall of a stainless steel pipe, it is necessary to aim a water gun at the pipe orifice of the stainless steel pipe, and then spray clear water into the stainless steel pipe through the pipe orifice of the stainless steel pipe. The clear water flushes the inner wall of the stainless steel pipe. However, in the actual cleaning process, there are firmly adhered dirt on the inner wall of the stainless steel pipe, and it is difficult to effectively clean it only by flushing with clear water. To solve the above problems, the embodiments of the present invention are provided with a plurality of structures such as a fixed cylinder 4, a water spray head 41, and a plugging rod 42. The specific use process is as follows: When in use, first place the stainless steel pipe to be cleaned into the soaking tank 2. There is a chemical solution inside the soaking tank 2. After soaking for a period of time, transfer the stainless steel pipe to the top of the cleaning rack 1. The specific transfer process of the stainless steel pipe can be through a manipulator or by a worker using a traveling crane, and it is specifically selected according to the actual on-site situation. When transferring the stainless steel pipe to the top of the cleaning rack 1, align the pipe orifice of the stainless steel pipe with the rotating shaft 43, and control the center line of the stainless steel pipe to coincide with the center line of the rotating shaft 43. At the same time, control the pipe orifice of the stainless steel pipe to be close to the rotating shaft 43, and then start cleaning the inner wall of the stainless steel pipe. It should be noted that when the electromagnet 421 installed inside the fixed cylinder 4 is energized, it will attract the plugging rod 42 made of metal. During cleaning, control the electromagnet 421 to be de-energized. In addition, a layer of diaphragm is provided on the surface of the electromagnet 421 to prevent the electromagnet 421 from contacting with clear water. During cleaning, the electromagnet 421 has no magnetism and no longer attracts and fixes the plugging rod 42. The water spray head 41 is externally connected to a water pump. When the externally connected water pump starts, it injects external clear water into the water spray head 41. Then the water spray head 41 sprays clear water into the fixed cylinder 4. The end of the plugging rod 42 located inside the fixed cylinder 4 moves towards the stainless steel pipe under the impact of the clear water. When the plugging rod 42 moves, the rotating shaft 43 is driven to move synchronously. The rotating shaft 43 drives the sponge block 46 at the end of the connecting spring 45 to move synchronously. In addition, a plurality of through holes are provided at the end of the plugging rod 42. The through holes located inside the fixed cylinder 4 will receive clear water and spray it out through the other end of the through holes. The clear water sprayed out from the through holes will act on the water baffle 44 on the shaft surface of the rotating shaft 43. The water baffle 44 is arranged in an inclined shape relative to the end face of the plugging rod 42. Therefore, when the water baffle 44 is impacted by the clear water, it will drive the rotating shaft 43 to rotate relative to the plugging rod 42. When the rotating shaft 43 rotates, it will drive the sponge block 46 at the end of the connecting spring 45 to rotate synchronously. When the sponge block 46 moves to the position of the pipe orifice of the stainless steel pipe and contacts the pipe orifice of the stainless steel pipe, the rotating sponge block 46 will generate friction with the pipe orifice of the stainless steel pipe. At the same time, the clear water sprayed out from the through holes on the plugging rod 42 will be sprayed into the pipe orifice of the stainless steel pipe and the sponge block 46 synchronously. Therefore, the dirt at the pipe orifice of the stainless steel pipe will be cleaned by the sponge block 46. Then, as the plugging rod 42 further moves, the rotating shaft 43 drives the sponge block 46 at the end of the connecting spring 45 to move synchronously. The sponge block 46 is squeezed and deformed, and the connecting spring 45 is bent. Then the sponge block 46 retracts into the stainless steel pipe and fully presses against the inner wall of the stainless steel pipe. When the insertion rod 42 moves, the side support assembly drives the support block 53 to move synchronously. When the support block 53 contacts the stainless steel pipe, the side of the support block 53 away from the insertion rod 42 just contacts the inner wall of the stainless steel pipe. Therefore, as the support block 53 is inserted into the stainless steel pipe, multiple support blocks 53 will support the insertion rod 42 inside the stainless steel pipe. Then, as the insertion rod 42 moves further, the insertion rod 42 completely disengages from the fixed cylinder 4. At this time, the drive assembly is activated, and the drive assembly drives the drive chain 61 to rotate. The drive chain 61 meshes with the teeth in the drive groove on the drive wheel 532. As the drive chain 61 rotates, the drive wheel 532 is driven to rotate synchronously. The drive wheel 532 is located in the transmission notch 531 at the uppermost position to support the support block 53. When the support block 53 enters the stainless steel pipe, the wheel surface of the drive wheel 532 is covered with a rubber layer, and the wheel surface of the drive wheel 532 will press against the inner wall of the stainless steel pipe. The drive chain 61 is embedded in the drive groove and will not contact the inner wall of the stainless steel pipe. As the drive wheel 532 rotates, the drive wheel 532 will drive the support block 53 to move deeper inside the stainless steel pipe. The support block 53 drives the insertion rod 42 to move synchronously through the support assembly, and the insertion rod 42 drives the rotating shaft 43 to move synchronously. The rotating shaft 43 drives the sponge block 46 at the end of the connecting spring 45 to move synchronously. During the movement of the insertion rod 42, the water spray head 41 continuously sprays clear water, and the clear water enters the stainless steel pipe through the fixed cylinder 4, also impacting the end of the insertion rod 42 inside the stainless steel pipe; Specifically, clean water can flow through the plug rod 42 through the outside of the plug rod 42, and clean water can also flow through the plug rod 42 through the through hole opened at the end of the plug rod 42. The clean water of the above two parts passing through the plug rod 42 will continuously impact the water baffle 44 on the axial surface of the rotating shaft 43, so the water baffle 44 will continuously drive the rotating shaft 43 to rotate, and the rotating shaft 43 drives the sponge block 46 at the end of the connecting spring 45 to rotate inside the stainless steel pipe. As the plug rod 42 moves inside the stainless steel pipe, the sponge block 46 will cooperate with the clean water to clean the inner wall of the stainless steel pipe, which is more convenient than single Purely through the clean water flushing, the cleaning effect is better, can fully clean the more solid dirt attached to the inner wall of the stainless steel pipe; it should be pointed out that there will be friction when the sponge block 46 rotates, at this time the torque required to rotate the shaft 43 is large, and then the torsional torque required to increase the water baffle 44 is large, so the staff needs to adaptively increase the power of the external water pump of the water spray head 41 so that the water flow speed in the stainless steel pipe can drive the water baffle 44 to rotate, and when the plug rod 42 moves away from the end of the fixed cylinder 4 to align with the pipe mouth of the stainless steel pipe When the lever 42 is stopped, the shaft 43 is located outside the stainless steel tube, and then the connecting rod 42 is controlled to return to its original position, and the shaft 43 is synchronously returned to its original position. When the shaft 43 returns to its original position, it rotates synchronously, driving the sponge block 46 at the end of the connecting spring 45 to retract into the stainless steel tube. In this process, the sponge block 46 will squeeze the tube mouth of the stainless steel tube and generate friction. Then, when the sponge block 46 is retracted into the stainless steel tube, the tube mouth on the other side of the stainless steel tube that has not been cleaned will be cleaned. Then, during the return movement of the connecting rod 42, the connecting rod 42 will first be inserted into the fixed tube 4. Then, the supporting block 53 connected to the supporting assembly of the connecting rod 42 will be separated from the stainless steel tube. At the same time, the electromagnet 421 is energized, and the electromagnet 421 is controlled to adsorb and fix the connecting rod 42, so that the connecting rod 42 is stabilized inside the fixed tube 4. It should be pointed out that the support blocks 53 at the bottom and on the left and right sides are provided with a plurality of balls on the side away from the connecting rod 42. When the support blocks 53 move inside the stainless steel tube, the balls can reduce the friction force on the inner wall of the stainless steel tube, thereby protecting the stainless steel tube. The entire process is automatically controlled by a microcomputer, which is convenient and simple, with excellent cleaning effect. After the inner wall of the stainless steel pipe is cleaned, the staff only needs to rinse the outer surface with a water gun, and can wipe it with a cloth during the rinsing process. This process is not shown in the embodiment of the present invention. In addition, the staff can also feed the cloth into the inside of the stainless steel pipe and use a long rod to drive the cloth to wipe and clean the inside of the stainless steel pipe. However, it is very inconvenient to clean a long stainless steel pipe by feeding the cloth. The staff needs to drive the cloth to move continuously and wipe the inner wall of the stainless steel pipe. Not only does the long rod take up space, but the cloth is also easily blocked inside the stainless steel pipe during cleaning. It is also very difficult for the staff to drive the cloth, which is difficult to apply to the cleaning of large quantities of stainless steel pipes. Based on this, the embodiment of the present invention has high practical significance.

[0023] The support assembly includes a first cylinder 5, the end of the first cylinder 5 is fixedly connected to the side of the plug-in rod 42, a first guide rod 51 is inserted into the interior of the first cylinder 5, a telescopic spring 52 is fixedly connected between one end of the first guide rod 51 located inside the first cylinder 5 and the inner wall of the first cylinder 5, and the end of the first guide rod 51 located outside the first cylinder 5 is fixedly connected to the surface of the support block 53; the end of the support block 53 close to the cleaning rack 1 is fixedly connected to a guide inclined plate 54, and the inclined direction of the guide inclined plate 54 points to the center line of the rotating shaft 43; for stainless steel of different diameters The pipe works as follows during cleaning: when the support block 53 is blocked by the small diameter stainless steel pipe mouth during movement, the guiding inclined plate 54 is set to align with the end of the support block 53. When the support block 53 moves, since the guiding inclined plate 54 is tilted toward the center line of the rotating shaft 43, the diameter of the circle formed by the ends of the multiple guiding inclined plates 54 away from the support block 53 (not shown in the drawings of the specification) is smaller than the diameter of the stainless steel pipe. Therefore, the end of the guiding inclined plate 54 away from the support block 53 will be inserted into the interior of the stainless steel pipe, and then the guiding support block 53 will enter the stainless steel pipe. When the diameter of the stainless steel pipe is large, the telescopic spring 52 drives the support block 53 connected to the end of the first guide rod 51 to move, so that the support block 53 drives the guiding inclined plate 54 to move away from the connecting rod 42, thereby making the guiding inclined plate 54 can continue to guide the support block 53 into the interior of the stainless steel pipe through the inclined surface. The staff only needs to adjust the length of the first cylinder 5 and the internal telescopic spring 52 based on the size of the stainless steel pipe. The size range of the stainless steel pipe to be cleaned based on the above embodiment of the present invention is wide and convenient to use. It should be pointed out that when the guiding inclined plate 54 guides the support block 53 into the interior of the stainless steel pipe, the ball on the support block 53 will temporarily be squeezed with the pipe mouth of the stainless steel pipe. However, when the ball is squeezed, the squeezing force will be synchronously transmitted to the telescopic spring 52 through the support block 53 and the first guide rod 51. The telescopic spring 52 contracts synchronously, so that the support block 53 drives the ball to retract into the interior of the stainless steel pipe. The strength of the stainless steel pipe is large, so the ball will not cause damage to the pipe mouth of the stainless steel pipe.

[0024] A lifting hydraulic cylinder 12 is arranged below the cleaning rack 1. The output end of the lifting hydraulic cylinder 12 is fixedly connected with a support frame 11. The top end of the support frame 11 is fixedly connected with the bottom end of the cleaning rack 1. A plurality of receiving trays 13 are fixedly connected to the top end of the cleaning rack 1. The receiving trays 13 are used for supporting the stainless steel pipes to be cleaned. For the cleaning of stainless steel pipes of different sizes, it is necessary to make the center line of the stainless steel pipe coincide with the center line of the rotating shaft 43. Therefore, the lifting hydraulic cylinder 12 is provided. When transferring the stainless steel pipe to the top end of the cleaning rack 1, the top end of the receiving tray 13 receives the stainless steel pipe. The top end of the receiving tray 13 is arranged in an arc-shaped depression. Therefore, when the stainless steel pipe is received by the receiving tray 13, it will remain stable and is difficult to shake left and right, so that the center line of the stainless steel pipe and the center line of the rotating shaft 43 are on the same vertical plane. At the same time, the lifting hydraulic cylinder 12 is started, and the height of the cleaning rack 1 is adjusted through the support frame 11, so that the center line of the stainless steel pipe and the center line of the rotating shaft 43 are at the same height. Combining the above condition that the center line of the stainless steel pipe and the center line of the rotating shaft 43 are on the same vertical plane, it can be concluded that the center line of the stainless steel pipe coincides with the center line of the rotating shaft 43, which is convenient for the subsequent cleaning process.

[0025] The driving assembly includes a driving motor 62. The driving motor 62 is fixedly connected to the top end of the fixed cylinder 4. A gear is installed at the output end of the driving motor 62. A transmission chain 61 is meshed and sleeved on the gear. A fastening assembly is arranged between the gear and the driving wheel 532. The fastening assembly is used to drive the transmission chain 61 to remain taut. When the driving assembly works, the driving motor 62 is started. The output end of the driving motor 62 drives the gear to rotate. The gear drives the transmission chain 61 to rotate. During this process, the fastening assembly controls the transmission chain 61 to remain in a taut state to ensure the normal use of the transmission chain 61 during use.

[0026] The fastening assembly includes a fixed frame 6 fixedly connected to the top end of the fixed cylinder 4. An L-shaped notch is opened inside the fixed frame 6. The transmission chain 61 is kept horizontal through the L-shaped notch. A plurality of receiving rollers 60 are rotatably arranged at the corner of the vertical part of the L-shaped notch. A tightening roller 64 is provided at the part of the transmission chain 61 passing through the L-shaped notch. The transmission chain 61 is sleeved on the surface of the tightening roller 64. Both ends of the tightening roller 64 are rotatably connected to a tightening frame 63. A pair of sliders 631 are fixedly connected to both ends of the tightening frame 63. A pair of slide rails 7 fixedly connected to the top of the fixed cylinder 4 are provided at both ends of the tightening frame 63. The sliders 631 are embedded in the tracks of the slide rails 7. A pull rope 65 is fixedly connected to the side of the tightening frame 63 away from the fixed frame 6. A weight 66 is fixedly connected to the end of the pull rope 65 away from the tightening frame 63. A railing 71 is fixedly connected to the end of the slide rail 7 away from the fixed cylinder 4. The pull rope 65 is supported by the railing 71; when the transmission chain 61 rotates, the part of the transmission chain 61 passing through the L-shaped notch is supported by the tightening roller 64. The slider 631 at the bottom end of the tightening frame 63 connected to the tightening roller 64 slides inside the slide rail 7, and a pull rope 65 is connected to the side of the tightening frame 63. The weight 66 at the end of the pull rope 65 is supported by the railing 71 at the end of the slide rail 7. Therefore, the gravity of the weight 66 is the same as the pulling force of the pull rope 65 on the tightening frame 63, and the length of the pull rope 65 can be adjusted as needed; when the driving wheel 532 moves, the transmission chain 61 is pulled to move synchronously into the stainless steel pipe. During this process, the weight 66 is pulled to move upward. The weight of the weight 66 remains unchanged. Therefore, the pulling force of the pull rope 65 on the tightening frame 63 remains unchanged, and the pulling force of the tightening frame 63 driving the tightening roller 64 to pull the transmission chain 61 is the same. The transmission chain 61 remains in a tightened state to ensure the transmission effect; in addition, a plurality of receiving rollers 60 are rotatably provided at the corner of the vertical part of the L-shaped notch. The receiving rollers 60 receive the rotation of the transmission chain 61 and limit the transmission chain 61 to maintain the transmission shape, that is, to prevent the transmission chain 61 from generating friction by itself when rotating.

[0027] A regulating hydraulic cylinder 8 is fixedly installed on the side of the slide rail 7. The output end of the regulating hydraulic cylinder 8 is fixedly connected to a positioning plate 81. A pulling roller 82 is rotatably connected to the side of the positioning plate 81. The pulling roller 82 penetrates through the transmission chain 61. A pair of limiting rollers 91 are symmetrically arranged on the top of the transmission chain 61 based on the pulling roller 82. The ends of the limiting rollers 91 are rotatably connected to a positioning frame 9, and the positioning frame 9 is fixedly connected to the top of the slide rail 7; when in use, the staff controls the output end of the regulating hydraulic cylinder 8 to drive the positioning plate 81 to move upward. The positioning plate 81 drives the pulling roller 82 to move upward. The pulling roller 82 will drive the transmission chain 61 to bulge upward. And under the limitation of the limiting rollers 91, the transmission chain 61 is driven to continuously bulge upward. Therefore, initially, the horizontal part of the transmission chain 61 is transferred to the vertical direction, and the staff can set other pulling rollers 82 at different positions as needed, effectively preventing the transmission chain 61 from occupying too much space. It should be noted that when the transmission chain 61 moves into the stainless steel pipe, it is necessary to control the regulating hydraulic cylinder 8 to synchronously reduce the output to avoid interference; in addition, it can avoid the need for a long lifting distance when using the weight 66, which is not convenient for saving space.

[0028] A covering pressure roller 10 is arranged between the driving motor 62 and the fixed cylinder 4. The covering pressure roller 10 presses the top of the transmission chain 61. The end of the covering pressure roller 10 is rotatably connected with a connecting frame, and the bottom end of the connecting frame is fixedly connected to the surface of the fixed frame 6. When the transmission chain 61 is inserted into the stainless steel pipe, the covering pressure roller 10 will press the top end of the transmission chain 61, causing the top end of the transmission chain 61 to sink downward, so as to avoid the transmission chain 61 contacting the pipe orifice of the stainless steel pipe and damaging the pipe orifice of the stainless steel pipe.

[0029] A material conveying pipe 432 is inserted through the side surface of the rotating shaft 43. The end of the material conveying pipe 432 far from the rotating shaft 43 is inserted through the inserting rod 42 and is located outside the fixed cylinder 4 at the initial stage. The end of the rotating shaft 43 far from the inserting rod 42 is fixedly connected with a sand blasting head 431 communicated with the material conveying pipe 432. The material conveying pipe 432 is made of wear-resistant rubber, and an abrasive conveying mechanism is externally connected to the material conveying pipe 432. Specifically, compressed air is used to push the abrasive into the material conveying pipe 432. When the rotating shaft 43 moves inside the stainless steel pipe, the material conveying pipe 432 moves synchronously. The material conveying pipe 432 is rotatably connected with the rotating shaft 43 without rotational interference, and the abrasive entering the material conveying pipe 432 will enter the sand blasting head 431 and then be sprayed onto the inner wall of the stainless steel pipe to realize the cleaning of the oxide layer on the inner wall of the stainless steel pipe and further improve the cleaning effect. It should be noted that a strengthening material is added inside the material conveying pipe 432 made of wear-resistant rubber, so that the material conveying pipe 432 has a higher strength. When the rotating shaft 43 returns to its original position, it can drive the material conveying pipe 432 to return to its original position synchronously, avoiding the interference of the material conveying pipe 432 bending between the fixed cylinder 4 and the stainless steel pipe during the return movement.

The output end of the electric telescopic rod 14 is fixedly connected with a sealing ring 15. A collecting cylinder 16 is installed on the side surface of the sealing ring 15. The end of the collecting cylinder 16 far from the sealing ring 15 is fixedly connected with a filter plate 17. During use, the sealing ring 15 is inserted into the pipe orifice of the stainless steel pipe. The abrasive sprayed into the stainless steel pipe is ejected from the pipe orifice of the stainless steel pipe through water flow, then enters the collecting cylinder 16 through the sealing ring 15, and finally is filtered and collected through the filter plate 17, and the staff can recycle it regularly. The output end of the electric telescopic rod 14 is fixedly connected with the sealing ring 15. Therefore, the electric telescopic rod 14 can control the position of the sealing ring 15 and can control the sealing ring 15 to disengage from the pipe orifice of the stainless steel pipe when transferring the stainless steel pipe, which is convenient for use. In addition, an annular airbag is fixedly connected inside the sealing ring 15. For stainless steel pipes with different diameters, by controlling the expansion degree of the annular airbag, the sealing ring 15 can continuously seal the pipe orifice of the stainless steel pipe, which is convenient for use.
