Description

Technical Field

[0001] This invention relates to the field of pipeline production equipment technology, specifically to an automated production line equipment for anti-corrosion of steel pipes. Background Technology

[0002] Steel pipes refer to steel materials with a hollow cross-section, whose length is much greater than its diameter or circumference. According to the production process, they are divided into seamless steel pipes and welded steel pipes. Steel pipe corrosion protection is mainly achieved by applying a protective layer to the surface of the steel pipe to isolate corrosive media, thereby greatly extending its service life. The main anti-corrosion technologies include epoxy coal tar pitch, fusion bonded epoxy powder, three-layer polyethylene, polyethylene coating, TPEP anti-corrosion, and cement mortar lining.

[0003] The patent application with application number CN201911379754.1 mentions "a corrosion-resistant anisotropic stainless steel pipe production equipment and process method". This patent uses a second horizontal adjustment component to adjust the position of the second clamping mechanism relative to the first clamping mechanism. Then, the two ends of the stainless steel pipe are clamped and installed on the first clamping mechanism and the second clamping mechanism respectively. After that, the first horizontal adjustment component is used to adjust the cutting component to be directly above the cutting point of the stainless steel pipe. Then, the extension and retraction function of the electric telescopic rod is used to push the cutting component downward to complete the cutting operation of the stainless steel pipe.

[0004] However, existing technologies for anti-corrosion treatment of steel pipes generally involve simultaneous spraying of the inside and outside of the pipe. During operation, the steel pipe is affected by the clamping equipment, which can easily create blind spots in the treatment, requiring secondary repairs after the treatment. In addition, during the spraying anti-corrosion treatment, most equipment cannot perform synchronous curing, causing the coated anti-corrosion material to flow easily during movement due to gravity, resulting in uneven application and greatly affecting the quality and uniformity of the anti-corrosion treatment of the steel pipe.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. Equipped with a dual-spray clamping assembly, the steel pipe is rotated by a friction moving roller. This, along with a synchronous sleeve frame, direct spray treatment pipe, and direct spray atomizing head, provides anti-corrosion treatment to the inside of the steel pipe. A shifting motor, clamping cylinder, and flexible anti-slip block further rotate the steel pipe, providing anti-corrosion treatment to the outside. A dual-chamber inlet / outlet box, a dual-chamber heat exchange box, a direct spray annular sleeve, and a suction annular sleeve regulate the temperature and humidity of the environment. Independent clamping at two different positions prevents spraying dead zones caused by clamping and positioning, eliminating the need for subsequent large-area repairs. Continuous injection of dry hot air and extraction of humid hot air, along with heat exchange, controls the temperature and humidity of the environment during spraying and curing, increasing the curing and drying rate, ensuring a constant internal temperature, and preventing excessive temperature fluctuations that could lead to thermal expansion and contraction and coating cracking. This ensures both production efficiency and stability. By moving the lead screw to move the moving limit frame and the smooth inner clamp, and coordinating with the processing gear and stabilizing rack to adjust the position of the air intake multi-spray sleeve, a dry and constant temperature air circulation is formed near the steel pipe, realizing the synchronous coordination of steel pipe transportation and curing. With the help of friction cleaning rollers and straight sliding cleaning blocks, the steel pipe surface is cleaned in close contact. Through synchronous cleaning of the inner and outer layers, and by using the inner spray isolation box, outer spray isolation box, horizontal inner treatment box and horizontal isolation box to continuously connect and isolate, the cleanliness of the processing environment and the steel pipe is further improved, reducing the impact of dust, fine adhering objects and other contaminants on the adhesion of the anti-corrosion coating, and improving the adhesion strength and stability. By combining simultaneous multi-position cleaning during feeding and spraying, segmented internal and external clamping spraying, constant temperature and humidity curing during spraying, and mobile constant temperature and humidity curing, this technology effectively solves the problem of spraying dead corners caused by the clamping equipment during steel pipe anti-corrosion spraying. It also solves the problem of uneven distribution of anti-corrosion material due to separation of curing and spraying. Utilizing external and internal separation clamping, segmented internal and external spraying is achieved. Combined with a continuously connected constant temperature and humidity environment and self-circulation of air, this enables continuous operation of simultaneous spraying curing and subsequent complete curing. This eliminates the need for large-area repair and filling of the steel pipe during production, effectively reducing uneven distribution of the anti-corrosion coating. Thus, while ensuring production efficiency, it greatly improves the uniformity of the anti-corrosion coating distribution and the effectiveness and quality of steel pipe anti-corrosion.

[0017] 2. Equipped with a testing and stabilization component, the swing processing frame and contact voltage detector are rotated by a torsion spring, so that the side end of the contact voltage detector contacts the side end of the steel pipe. The anti-corrosion coating on the surface of the steel pipe is subjected to electric spark leak detection using a detection analyzer, processing wires, and contact voltage detector. The spraying process is observed and processed simultaneously by a processing camera, realizing rapid detection and processing after anti-corrosion spraying. The reciprocating electric slide rails move the inner and outer processing frames. The position of the flexible deformation monitor is adjusted using a processing air pump, air injection control pipe, and expansion airbag. The flexible deformation monitor detects the thickness and uniformity of the pipeline anti-corrosion layer. The position of the liquid suction repair patch is changed by the fitting airbag. Anti-corrosion coating is injected in conjunction with the liquid injection control pipe and liquid injection linkage pump. Through multi-stage linkage of electric spark detection, camera visual inspection, and contact sensor detection, and anti-corrosion brushing and coating are performed, the thickness of the steel pipe anti-corrosion layer is supplemented and some defects are repaired. This allows for rapid and timely correction of the anti-corrosion layer during the steel pipe anti-corrosion production process, ensuring the quality of the anti-corrosion forming. It also prevents the separation of the first anti-corrosion layer from the second layer after complete curing, which would affect the anti-corrosion effect and quality, thus greatly improving the actual effect and quality of steel pipe anti-corrosion treatment.

[0018] In summary, by combining the dual-spray clamping assembly and the testing and stabilizing assembly, and utilizing the first stage of internal and external step-by-step anti-corrosion spraying and preliminary curing treatment, the second stage of internal and external step-by-step anti-corrosion correction and supplementary treatment and secondary curing treatment, the thickness of the anti-corrosion layer and the uniformity of the anti-corrosion steps are guaranteed. Combined with multi-stage continuous production and synchronous production processing, the waiting time for loading and unloading is reduced, and production efficiency is guaranteed while improving product quality.

[0024] The working principle and usage process of this invention are as follows: When performing surface anti-corrosion treatment on steel pipes, workers hoist the required steel pipe material to the treatment location using hoisting equipment. Grinding and cleaning equipment are then used to remove rust, slag, and oil from the steel pipe surface. After cleaning, the steel pipe is transported by handling equipment to the loading position of the inner spray isolation box 2 at the side end of the flat support clamping frame 1. At this time, the equipment is powered by an external controller. When the steel pipe is picked up by the external loading clamping equipment, it is then injected with a sleeve fluid. The pressure cylinder 604 drives the insertion sleeve synchronous frame 605 to be pulled out from the inner spray isolation box 2. The opening and closing hydraulic cylinder 602 drives the opening and closing integrated frame 603 to rise along the inner spray isolation box 2, so that the opening and closing integrated frame 603 and the insertion sleeve synchronous frame 605 are separated from the inner spray isolation box 2, thereby fully opening the inner spray isolation box 2. After opening, the steel pipe is inserted into the side end of the friction moving roller 615 inside the inner spray isolation box 2 through the external feeding clamping device. After the insertion is completed, the external feeding clamping device releases the steel pipe and repeats the operation of picking up and putting down the steel pipe. During the placement of the steel pipe, the pressing spring rod 611 drives the pressing synchronous frame 612 to move along the inner spray isolation box 2, causing the side end of the friction cleaning roller 613 to contact the outer surface of the steel pipe. After the steel pipe is completely placed, the opening and closing hydraulic cylinder 602 drives the opening and closing integrated frame 603 to move downward along the inner spray isolation box 2, so that the opening and closing integrated frame 603 engages with the inner spray isolation box 2. After engagement, the inserting hydraulic cylinder 604 drives the inserting synchronous frame 605 to insert into the inner side of the inner spray isolation box 2, and so that the inserting synchronous frame 605 is inserted into one end of the inner side of the steel pipe. When the front end of the synchronous frame 605 just enters the inside of the steel pipe, the contact spring rod 606 drives the straight sliding cleaning block 607 to fit into the inside of the steel pipe. At this time, the rotary motor 616 is started. The rotary motor 616 and the double-outlet belt drive box 614 drive the friction moving roller 615 to rotate. The friction moving roller 615 pushes the steel pipe to rotate. At this time, the inner end of the steel pipe contacts the surface of the straight sliding cleaning block 607, and the outer end of the steel pipe contacts the side end of the friction cleaning roller 613. Through synchronous internal and external rotation and brushing, the residual debris and dust on the surface of the steel pipe are cleaned to ensure the cleanliness of its surface. While the steel pipe rotates, the pressure-stabilized extraction pump 726 and the direct spray treatment pipe 620 extract the anti-corrosion liquid quick-drying coating from the liquid storage tank 725. The liquid quick-drying coating is sprayed out as atomized liquid along the direct spray treatment pipe 620 and the direct spray atomizing head 621. The atomized liquid is sprayed onto the inside of the steel pipe, and during the rotation, multi-position continuous spraying and forming treatment is achieved. At this time, dry air is extracted from the drying adsorption box 723 through the inlet and outlet treatment pipe 635 and the guide flow control fan 636. The dry air enters the inlet and outlet double cavity heat exchange box 610 along the inlet and outlet treatment pipe 635, and then enters the inside of the direct spray annular sleeve 608 along the inlet and outlet double cavity heat exchange box 610. When the dry air enters the inside of the direct spray annular sleeve 608, the air comes into contact with the electric heating mesh plate 724. At this time, the air is heated. The heated air enters the inside of the steel pipe and performs slow direct blowing drying treatment on the anti-corrosion coating attached to the surface of the steel pipe. When dry hot air comes into contact with the coating and dries it, humid hot air is generated. This humid hot air is drawn in by the annular sleeve 609 and enters the inner side of the dual-chamber heat exchange box 610. It then returns to the inner side of the drying adsorption box 723 through the inlet / outlet processing pipe 635, thus achieving air drying and dehydration. During the flow of low-temperature dry hot air and high-temperature humid hot air, the cold air and hot air exchange heat through the dual-chamber heat exchange box 610, achieving the recovery and reuse of heat resources. Furthermore, through the circulation of dry air, the coating can be rapidly cured and the internal humidity can be controlled while the coating is being sprayed and cured, preventing excessive moisture from affecting the stability of the coating adhesion. The processing camera 623 can be used to observe the spraying position, making it easy to adjust the spraying speed in time and ensure the uniformity and stability of the adhesion. After the internal coating of the steel pipe is completed, the opening and closing cylinder 714 drives the opening and closing sealing cover 715 to move along the inner spray isolation box 2 to open the inner spray isolation box 2. The outer spray isolation box 3 is opened by opening and closing the electric door 716. The pick-up and release cylinder 627 drives the pick-up and release sliding block 628 to move and insert it into the outer end of the steel pipe inside the inner spray isolation box 2. The clamping cylinder 630 drives the flexible anti-sliding block 631 to clamp the steel pipe. After clamping, the pick-up and release cylinder 627 drives the pick-up and release sliding block 628 to return to the inner side of the translation inner box 4, so as to realize the material removal process of the steel pipe after the internal coating is completed. After the steel pipe is fully inserted into the translational inner treatment box 4, the torsion spring 718 drives the swing treatment frame 719 and the contact voltage detector 720 to rotate along the moving limit frame 626, so that the side end of the contact voltage detector 720 contacts the side end of the steel pipe. The anti-corrosion coating on the surface of the steel pipe is subjected to electric spark leak detection treatment by the detection analyzer 722, the treatment wire 721 and the contact voltage detector 720. At the same time, the opening and closing cylinder 714 drives the opening and closing sealing cover 715 to reset, and the opening and closing electric door 716 to reset. After the reset and closure are completed, the above operation is repeated inside the inner spray isolation box 2 to place the new steel pipe inside for spraying production treatment. During the second loading of the inner spray isolation box 2, the steel pipe with the preliminary coating completed inside the translation inner treatment box 4 is rotated along the translation inner treatment box 4 by the hydraulic motor 624 driving the moving screw 625. The moving screw 625 drives the moving limit frame 626, the pick-and-place sliding block 628 and the steel pipe to move along the translation inner treatment box 4. When the moving limit frame 626 moves, the processing gear 633 moves synchronously, but the processing gear 633 is limited by the stabilizing rack 634 and meshes with the stabilizing rack 634. The stabilizing rack 634 pushes the processing gear 633 to rotate along the moving limit frame 626. At this time, the air intake multi-spray sleeve 632 rotates, which, together with the inlet and outlet processing pipe 635, the guide flow control fan 636, the drying adsorption box 723 and the electric heating grid plate 724, heats and dries the air and circulates it. With the rotation exhaust, a circulation is formed inside the steel pipe. With the temperature and humidity monitor 717, the temperature and humidity are monitored to achieve the continued drying of the anti-corrosion coating. When the steel pipe, after being leak-tested by spark, is moved to the middle of the sliding inner treatment box 4, and when it needs to be repaired, filled, or uniformly treated, the sliding inner treatment box 4 is opened by the electric door 716. The reciprocating electric slide rail 701 drives the external insertion treatment frame 703 to move along the flat support positioning frame 1, so that the external insertion treatment frame 703 is inserted into the steel pipe. Air is injected into the expansion air bladder 704 by the treatment air pump 710 and the air injection operation pipe 709. The expansion air bladder 704 expands and pushes the flexible deformation monitor 705 to move, so that the side end of the flexible deformation monitor 705 contacts the pre-cured anti-corrosion layer. At this time, the reciprocating electric slide rail 701 drives the external insertion treatment frame 703 to move continuously to detect the flatness of the inside of the pipe and the thickness of the anti-corrosion layer. At the same time, air is injected into the airbag 706, and the anti-corrosion coating inside the liquid storage tank 725 is extracted by the liquid injection operation pipe 708 and the liquid injection linkage pump 711. The coating is then injected into the position of the liquid suction repair patch 707. At this time, the discharge speed of the liquid injection operation pipe 708 is controlled by the processing linkage valve 712, and the contact position between the liquid suction repair patch 707 and the anti-corrosion layer of the steel pipe is controlled by the airbag 706. This achieves the replenishment of the anti-corrosion layer of the steel pipe and the filling of some defects. By carrying out inspection and repair filling simultaneously, the uniformity of the anti-corrosion layer and the overall sealing treatment are achieved. After processing, the reciprocating electric slide rail 701 drives the external insertion processing frame 703 to move and reset, and the moving screw 625 drives the moving limit frame 626 to move to the end of the translation inner processing box 4 near the outer spray isolation box 3. At this time, the opening and closing process of the sealing cover 715 and the opening and closing process of the electric door 716 are repeated. The pick-up and put-down cylinder 627 drives the pick-up and put-down sliding block 628 to place the steel pipe into the inner side of the outer spray isolation box 3. At this time, the clamping cylinder 630 and the flexible anti-sliding block 631 at the side end of the pick-up and push operation frame 619 located at the position of the rotating support frame 617 are inserted into the inside of the steel pipe. The clamping cylinder 630 drives the flexible anti-sliding block 631 to move and fit against the inner side of the steel pipe to clamp and support the steel pipe. After placement, the pick-up and put-down cylinder 627 drives the pick-up and put-down sliding block 628 to reset, and the moving screw 625 drives the moving limit frame 626 to reset. The process of picking up and putting down the rising steel pipe and repairing is repeated to achieve continuous production processing. After the steel pipe is placed, the rotating support frame 617 and the push-pull operation frame 619 are rotated by the shift motor 637, thereby causing the steel pipe to rotate slowly. During the slow rotation of the steel pipe, anti-corrosion coating is injected through the direct spray treatment pipe 620, the direct spray nozzle 621 and the pressure stabilizing extraction pump 726. The direct spray nozzle 621 is used to spray the anti-corrosion coating on the outside of the steel pipe. During the spraying process, dry air is injected into the partitioned double-chamber inlet and outlet box 622 through the inlet and outlet treatment pipe 635 and the guide speed control fan 636. The air is heated by the electric heating mesh plate 724 and flows to the coating on the outer surface of the steel pipe to dry the coating. The dried humid hot air then returns to the inside of the drying adsorption box 723 through the air inlets at the top and bottom of the side of the partitioned double-chamber inlet and outlet box 622, realizing airflow circulation and synchronous curing of the spraying. After the outer side of the steel pipe is sprayed and initially dried and cured, the external spray isolation box 3 is moved along the horizontal support bracket 1 by adjusting the electric slide rail 601, so that the side end of the external spray isolation box 3 contacts the side end of the horizontal partition box 5. The external spray isolation box 3 and the horizontal partition box 5 are opened by opening and closing cylinder 714, opening and closing sealing cover 715 and opening and closing electric door 716. The lifting and pushing operation frame 619 is moved along the rotating support frame 617 by the lifting and pushing electric slide rail 618, so that the steel pipe is placed into the horizontal partition box 5. Inside, at this time, the clamping cylinder 630 at the position of the smooth inner clamp 629 drives the flexible anti-slip block 631 to fit against the inner wall of the steel pipe to support the steel pipe. After the steel pipe is fixed and placed, the lifting and pushing operation frame 619 is reset and returned to the inside of the outer spray isolation box 3 by the lifting and pushing electric slide rail 618. Then, the adjusting electric slide rail 601 drives the outer spray isolation box 3 to reset. After the outer spray isolation box 3 is reset, the above operation of anti-corrosion spraying on the outside of the steel pipe is repeated to achieve continuous production processing. After the steel pipe is fixed to the side end of the smooth inner clamp 629, the torsion spring 718 drives the swing treatment frame 719 and the contact voltage detector 720 to rotate along the smooth inner clamp 629, so that the side end of the contact voltage detector 720 contacts the inner end of the steel pipe. The anti-corrosion coating on the surface of the steel pipe is subjected to electric spark leak detection treatment by the detection analyzer 722, the treatment wire 721 and the contact voltage detector 720. At the same time, the opening and closing cylinder 714 drives the opening and closing sealing cover 715 to reset, the opening and closing electric door 716 to reset, and the hydraulic motor 624 drives the moving screw 625 to rotate along the translation partition box 5. The moving screw 625 drives the smooth inner clamp 629 and the air inlet multi-spray sleeve 63. 2. The steel pipe moves along the sliding partition box 5. When the smooth inner clamp 629 moves, the processing gear 633 moves synchronously. However, the processing gear 633 is limited by the stabilizing rack 634 and meshes with the stabilizing rack 634. The stabilizing rack 634 blocks the processing gear 633 to rotate along the smooth inner clamp 629. At this time, the air intake multi-spray sleeve 632 rotates. In conjunction with the inlet and outlet processing pipe 635, the guide flow control fan 636, the drying adsorption box 723 and the electric heating grid plate 724, the air is heated, dried and circulated. With the rotation exhaust, a circulation is formed outside the steel pipe. With the temperature and humidity monitor 717, the temperature and humidity are monitored to achieve the continued drying of the anti-corrosion coating. When the steel pipe, after being leak-tested by spark, is moved to the middle of the sliding partition box 5, and when it needs to be repaired, filled, or uniformly treated, the sliding partition box 5 is opened by the electric door 716. The reciprocating electric slide rail 701 drives the inner insertion processing frame 702 to move along the flat support positioning frame 1, so that the inner insertion processing frame 702 is inserted into the outside of the steel pipe. Air is injected into the expansion air bladder 704 by the processing air pump 710 and the air injection operation pipe 709. The expansion air bladder 704 expands and pushes the flexible deformation monitor 705 to move, so that the side end of the flexible deformation monitor 705 contacts the pre-cured anti-corrosion layer. At this time, the reciprocating electric slide rail 701 drives the outer insertion processing frame 703 to move continuously to detect the flatness of the outside of the pipe and the thickness of the anti-corrosion layer. At the same time, air is injected into the airbag 706, and the anti-corrosion coating inside the liquid storage tank 725 is extracted by the liquid injection operation pipe 708 and the liquid injection linkage pump 711. The coating is then injected into the position of the liquid suction repair patch 707. At this time, the discharge speed of the liquid injection operation pipe 708 is controlled by the processing linkage valve 712, and the contact position between the liquid suction repair patch 707 and the anti-corrosion layer of the steel pipe is controlled by the airbag 706. This achieves the replenishment of the anti-corrosion layer of the steel pipe and the filling of some defects. By carrying out inspection and repair filling simultaneously, the uniformity of the anti-corrosion layer and the overall sealing treatment are achieved. After processing, the reciprocating electric slide rail 701 drives the external insertion processing frame 703 to move and reset, and the moving screw 625 drives the moving limit frame 626 to move to the end of the translation partition box 5 away from the external spray isolation box 3. At this time, the coated steel pipe is picked up by the external pick-and-place equipment to achieve the anti-corrosion forming treatment of the steel pipe. Then, the moving screw 625 drives the smooth inner clamp 629 to reset and repeats the rising operation to achieve continuous production processing of the steel pipe. By spraying the inside and outside of the steel pipe in stages and using continuous production, production efficiency is ensured while avoiding the omission of spraying positions caused by pipe clamping, which greatly improves the quality of the product.
