Description

Technical Field

[0001] This invention relates to the field of metal surface coating technology, and more specifically to an organic coating type anti-corrosion sucker rod armor processing device for rod head armor protection surface. Background Technology

[0002] The sucker rod is a key component of a rod pump oil extraction system. Its rod head connects to other components via threads to form the lifting system. This component is exposed to complex downhole media, including water, hydrogen sulfide, carbon dioxide, and chloride ions, and is subjected to alternating loads, making corrosion and wear particularly severe. The rod head area, especially the stress-concentrated, complex-shaped wrench-shaped section, has become a high-risk area for corrosion failure. Its durability directly determines the overall lifespan of the sucker rod and is also related to the cost and safety of oil production operations.

[0003] Currently, the main method for extending the life of sucker rod heads is to apply anti-corrosion treatment. Common processes include coating the surface with organic anti-corrosion coatings such as epoxy resin and polyethylene, or using processes such as thermal spraying and electroplating to form a metal protective layer. However, existing treatment methods generally have significant shortcomings: First, most processes rely on manual labor, such as manual rust removal, manual spraying, or brushing, resulting in low production efficiency, unstable coating quality, and product consistency easily affected by the operator's skill level. Second, for non-cylindrical structures such as wrenches, conventional spraying is difficult to achieve uniform coverage of all surfaces, easily leaving protective blind spots, which can lead to early corrosion. In addition, the pretreatment, coating, and curing processes are usually carried out intermittently at different stations, requiring multiple handling and interruptions, which is not only inefficient but may also damage the uncured coating and makes it difficult to achieve precise positioning throughout the process.

[0004] As oilfield development progresses towards deeper and ultra-deep wells and highly corrosive reservoirs, the performance requirements for the anti-corrosion coating on sucker rod heads are constantly increasing. Single organic or metallic coatings are no longer sufficient to meet such demanding operating conditions. Current technological trends favor the development of composite protection systems that combine the excellent chemical corrosion resistance of organic coatings with the superior mechanical wear resistance of metallic armor layers.

[0005] This has led to the development of a new type of organic-coated anti-corrosion sucker rod with an armored protective surface. This sucker rod has a multi-layered composite protective structure, forming a composite system of "organic anti-corrosion layer + metal armor layer". The inner organic anti-corrosion layer (primer and epoxy resin) provides excellent chemical corrosion protection and insulation properties, while the outer stainless steel armor layer has high mechanical strength, wear resistance and impact resistance. The armor layer covers critical parts of the rod head (such as the wrench side) to the middle section of the rod, providing more comprehensive and durable protection and significantly extending the service life of the sucker rod under harsh well conditions.

[0006] However, how to achieve efficient, automated, and high-quality molding of such composite coatings for sucker rods, especially the precise and uniform coating of the metal armor layer onto the complex rod head surface, remains a technical bottleneck that the industry urgently needs to overcome.

[0007] Therefore, there is an urgent need to develop a highly integrated and automated special molding device that can realize continuous operation of the entire process of sucker rod head from cleaning, anti-corrosion coating, armor coating to curing and shaping, fundamentally solving the existing problems in efficiency, quality and environmental protection, thereby manufacturing a highly reliable product with long-lasting composite protection capabilities.

[0041] Compared with the prior art, the beneficial effects of this invention include the following aspects: I. Overall Design and Layout Effect 1. The production line adopts a highly efficient continuous layout: a smooth material transfer path is constructed through a "Z"-shaped welded forming platform combined with the first transverse, longitudinal, and second transverse conveying units. This layout achieves fully automated continuous production from upstream cleaning to downstream solidification within a limited space, significantly improving production efficiency and reducing material transfer and manual operation in intermediate links.

[0042] 2. Highly modular and integrated features: The machine integrates multiple functional units such as surface cleaning, anti-corrosion spraying, armor spraying, and curing. Each unit has a clear structure and independent function, and they are closely connected through a conveyor system to form a complete automated processing system, which facilitates installation, commissioning, daily maintenance, and subsequent upgrades and modifications to meet process requirements.

[0043] II. Technical Effects of Each Functional Unit 1. Surface cleaning unit Using an ultrasonic generator for descaling is more effective than traditional spraying or brushing in removing fine and stubborn oil and oxides from the rod head surface, resulting in a more thorough cleaning. The side-clamp telescopic cylinder works in conjunction with the side-clamp positioning plate to automatically center and clamp the rod head, ensuring no blind spots in cleaning. A matching collection box centrally collects cleaning wastewater, meeting environmental protection requirements, thus achieving automated positioning and resource recovery.

[0044] 2. Anti-corrosion spraying unit The rod head is clamped by rotating the clamping mechanism (including the clamping turntable and lifting limit seat, etc.) and driven to rotate at a uniform speed. In conjunction with the anti-corrosion coating nozzle, the coating is sprayed to ensure that the organic anti-corrosion layer has a consistent thickness in all directions, avoid sagging or missed coating, and ensure the uniformity and quality of the coating. By integrating the temperature-controlled half-mold and temperature control module, the spraying environment temperature can be precisely controlled, promoting the leveling and curing process of the coating and improving the forming quality and performance of the anti-corrosion layer; It has flexible clamping adaptability: the rotating clamping mechanism is reasonably designed and can stably clamp and transfer rod heads of different specifications, with strong adaptability.

[0045] 3. Armored spraying unit The "flattening-closing" action is achieved by using a swingable armor forming mold, which completely wraps the rod head to form a sealed spraying chamber, allowing armor materials such as stainless steel to be sprayed in a controlled environment, ensuring complete coverage, especially for complex structures such as wrench squares, thereby achieving the forming of complex armor layers. Driven by a rotating chuck, the clubhead rotates continuously, and the hot-melt nozzle sprays multiple points from the inner wall of the mold, ensuring that the armor material is evenly adhered to the surface of the clubhead, forming a dense and firmly bonded metal protective layer, ensuring uniform and efficient coating. The design of the swing hinge seat and clearance ensures that the mold closing action and the rod head conveying and rotation are not interfered with, and the operation is stable and reliable.

[0046] 4. Curing and shaping unit The system uses electric heating tubes and a drying fan to generate forced convection, forming a uniform hot air field that blows from above towards the rod head. This allows for rapid and uniform curing and shaping of the anti-corrosion layer and armor layer, shortening process time and improving coating performance, thereby achieving efficient drying and curing. The inclined structure of the third lifting pallet and the alignment push plate automatically align the rod head and precisely position it at the drying station to ensure consistent curing effect.

[0047] III. Technical Effects of the Conveying and Lifting System Three conveying units and three lifting pallets work together to complete a series of automated operations such as horizontal conveying, lifting and detachment, workstation transfer and descent reset of the rod head, which can realize seamless material transfer. In particular, through the different inclined surface design of the lifting plate, the automatic sliding and turning of the rod head from the horizontal to the vertical and then back to the horizontal is cleverly realized, without the need for a complicated robotic arm, and the structure is simple and reliable. The lifting pallet lifts the rod head and detaches it from the conveyor roller at key workstations such as spraying and armoring, providing stable and precise operating conditions for rotation clamping and mold closing, thus ensuring processing accuracy.

[0084] like Figure 12 The second embodiment shown is a rod head armor protection surface organic coating type anti-corrosion sucker rod processed based on the armor forming device in the first embodiment. It includes a middle rod body 68, and rod heads 69 are welded to both ends of the middle rod body 68. The rod heads 69 are coated with an organic anti-corrosion layer 70 and an armor protection layer 71 from the inside to the outside. The organic anti-corrosion layer 70 includes a thermosetting primer coating and a modified epoxy resin layer. The armor protection layer 71 is made of stainless steel and extends from the rod head wrench position to the middle rod body 68.

[0085] When using this invention: First, each power input module 6 is started, and through the sprocket transmission mechanism, each transverse conveyor roller 5 and longitudinal conveyor roller 8 are driven to rotate synchronously; The sucker rod to be coated is placed horizontally on the first transverse conveying unit. When the sucker rod is conveyed to the bottom of the cleaning mounting frame 9, the side clamp telescopic cylinder 17 is extended, driving the two side clamp positioning plates 19 to move in opposite directions, pushing the sucker rod to the middle of the transverse conveying roller 5 and clamping it. The ultrasonic generator 20 is started to perform ultrasonic descaling. At the same time, the water supply pump 14 is turned on to inject cleaning water into the cleaning water supply tank 13, and then into the water distribution seat 15 through the cleaning water supply tank 13. Finally, the water is pressurized and sprayed out through the cleaning nozzle 16 to rinse and clean the surface of the sucker rod. The sprayed water falls into the collection tank 12 for recycling. After cleaning, the side clamp positioning plate 19 releases its grip on the sucker rod, thereby moving the sucker rod back onto the first transverse conveying unit and continuing to be conveyed by the transverse conveying roller 5. When the sucker rod is delivered directly below the first spray frame 21, the lifting drive module 67 is activated to drive the first lifting support plate 63 to rise. The horizontal top support plate 64 is used to lift the sucker rod upward, so that it is separated from the horizontal conveying roller 5. At the same time, the vertical extension telescopic cylinder 32 is controlled to extend, and the lifting limit seat 37 is driven to move downward. Then, by adjusting the position, the clamping limit post 38 is used to clamp and lift one end of the sucker rod. The horizontal extension telescopic cylinder 29 is controlled to extend, and the other end of the sucker rod is clamped on the guide clamping turntable 35. The steering drive motor 34 is activated to drive the sucker rod to rotate around the axis. Open the first check valve 27, inject the anti-corrosion coating into the first coating tank 25 through the first supply pipe 26, and then spray it out through the anti-corrosion coating nozzle 28 to coat the outer surface of the sucker rod head with an anti-corrosion layer. At the same time, open the mold closing telescopic module 22 to control the two temperature-controlled half molds 23 to join the mold, and open the temperature control module 24 to regulate the coating temperature. After the anti-corrosion coating has cured, the clamping mechanism is rotated to release the clamp on the sucker rod and transfer it back to the transverse conveying roller 5. Once the sucker rod is conveyed along the transverse conveying roller 5 to the position facing the longitudinal conveying unit, the lifting drive module 67 is started again. The sucker rod is lifted upward by the transverse top support plate 64. Since the upper surface of the transverse top support plate 64 is inclined, the lifted sucker rod will slide down the transverse top support plate 64 onto the longitudinal conveying roller 8. The sucker rod transferred to the longitudinal conveying roller 8 continues to be conveyed longitudinally. When it is conveyed to the area directly below the armored spraying frame 39, the lifting drive module 67 is activated to drive the second lifting support plate 65 to move upward. The longitudinal top support plate 66 lifts the sucker rod upward so that it faces the two rotating chucks 44. The electronic telescopic module is activated to control the rotating chucks 44 to extend. The clamping slider 45 clamps the two ends of the sucker rod. The rotation drive motor 43 is activated to drive the sucker rod to rotate around the axis. Start the swing drive module 48 to control the swing connecting plate 49 to swing from the horizontal state to the vertical state, so that the armor forming mold 50 switches from the flat state to the closed state, thereby completely wrapping the sucker rod head part. Open the feed check valve 42, inject the armor coating into the armor coating tank 40 through the coating feed pipe 41, then inject it into the coating transfer tank 51 through the feed hose 53, and finally spray it out through the hot melt nozzle 52 to perform armor coating treatment on the outer surface of the sucker rod tip. After the armor coating is completed, the sucker rod is moved back to the longitudinal conveyor roller 8 and continues to be longitudinally conveyed to the second transverse conveyor unit. At this time, the transverse conveyor roller 5 on the second transverse conveyor unit is stationary. The lifting drive module 67 is started to drive the third lifting support plate 72 to move upward. The transverse top support plate 64 is used to lift the sucker rod upward. The sucker rod slides down the upper inclined surface of the transverse top support plate 64 until it is stopped by the alignment push plate 62. The alignment push plate 62 is controlled to extend and push the sucker rod to the position directly below the drying and curing box 55. Two drying fans 56 are turned on respectively, and the power supply base 60 is turned on to supply power to the heating tube 59. The convective hot air is discharged through the air outlet 57 to dry and cure the surface of the sucker rod. After curing and shaping, the power input module 6 is activated to drive each transverse conveying roller 5 to rotate and convey the sucker rod laterally.
