Description

Technical Field

[0001] The utility model relates to the technical field of shipbuilding, in particular to a pipeline rust removal device for shipbuilding. Background Technique

[0002] In the process of shipbuilding and maintenance, the pipeline system is an indispensable and important part. However, due to the special working environment of the ship, the pipeline system is often exposed to high humidity and high salinity environments, which are prone to rust and dirt accumulation. These rusts and dirts will not only affect the normal use of the pipeline, but also lead to pipeline function failure and even pose potential safety hazards. Therefore, regular rust removal and cleaning of the pipeline are the key links to ensure the safe operation of the ship.

[0003] Traditional pipeline rust removal methods usually rely on manual operations, using tools such as wire brushes and sandpapers to manually remove rust. This method has a large labor intensity, low efficiency, and the rust removal effect is limited by the skills and physical strength of the operators, making it difficult to ensure the consistency of rust removal quality. In addition, manual rust removal may also cause damage to the pipeline surface and shorten the service life of the pipeline. Content of the Utility Model

[0004] To solve the above technical problems, the utility model provides a pipeline rust removal device for shipbuilding.

[0005] The utility model is realized by the following technical solutions: A pipeline rust removal device for shipbuilding includes an assembly cover. The middle of the surface of the assembly cover is fixedly connected with a motor base. A scraping component is arranged inside the motor base. Both sides of the surface of the assembly cover are fixedly connected with operating handles.

[0006] The scraping component includes a servo motor. The servo motor is fixedly installed on the inner wall of the motor base by bolts. The output end of the servo motor is fixedly connected with a transmission shaft. The outer surface of the transmission shaft is fixedly connected with a scraping plate. A plurality of circulation holes are arranged on the outer surface of the scraping plate.

[0007] Through the above technical solutions, by driving the transmission shaft and the scraping plate to rotate through the servo motor, the rust on the pipeline surface can be quickly and effectively removed. Compared with the traditional manual rust removal method, this mechanical means can significantly improve the rust removal efficiency. The design of the circulation holes on the scraping plate allows abrasives or cleaning liquids to pass through these holes and be evenly distributed on the surface to be treated, thereby ensuring the uniformity of the rust removal effect and avoiding local over-scraping or omission.

[0008] As a further improvement of the above solution, an internal screw hole is arranged on the surface of the assembly cover, and a plug is threadedly connected inside the internal screw hole.

[0009] Through the above technical solution, the design of the internal threaded hole with internal threads aims to achieve a convenient connection with external pump body equipment. Operators can easily dock the pump body equipment with the internal threaded hole, thereby realizing the function of accurately adding rust remover or cleaning liquid into the interior. This not only simplifies the injection process of the liquid medium but also ensures the sealing and accuracy of the addition process, effectively improving the rust removal and cleaning effects.

[0010] As a further improvement of the above solution, fastening bolts are fixedly connected to the peripheries of the outer surface of the assembly cover, and the assembly cover is fixedly installed with a flange through the fastening bolts.

[0011] Through the above technical solution, the fastening bolts can ensure a firm connection between the assembly cover and the flange, preventing loosening or detachment caused by vibration or external force during operation, and ensuring the stability of equipment operation. By means of bolt connection, the installation and disassembly of the flange become simple and fast, facilitating equipment maintenance, repair, and component replacement.

[0012] As a further improvement of the above solution, a pipeline body is fixedly connected to the interior of the flange.

[0013] Through the above technical solution, the setting of the flange enables the assembly cover to be quickly and firmly connected to the pipeline body, simplifying the installation and disassembly process of the equipment and improving work efficiency. The connection between the assembly cover and the pipeline body allows the scraper assembly to enter the interior of the pipeline and directly perform rust removal operations on the inner wall, improving the efficiency and thoroughness of rust removal. Through the connection of the flange, the assembly cover and the scraper assembly can be easily disassembled when needed to facilitate subsequent cleaning inspection and maintenance of the interior of the pipeline, increasing the flexibility of operation.

[0014] As a further improvement of the above solution, mounting holes are provided in the peripheries of the outer surface of the flange.

[0015] Through the above technical solution, the uniformly distributed mounting holes and the fastening bolts can disperse the stress at the connection, avoiding connection failure or component damage caused by stress concentration.

[0016] As a further improvement of the above solution, the fastening bolts are adapted to the mounting holes.

[0017] Through the above technical solution, the combined use of the fastening bolts and the mounting holes can effectively fix the relative positions of the flange and other components or pipeline systems, preventing displacement or loosening caused by external forces and enhancing the stability of the connection. When maintenance or disassembly is required, the flange can be quickly separated by loosening the fastening bolts, simplifying the disassembly process and improving the efficiency of maintenance work.

[0018] As a further improvement of the above solution, a rubber layer is provided on the outer surface of the operating handle.

[0019] Through the above technical solution, the rubber layer has good flexibility and elasticity, which can increase the friction coefficient of the handle surface, making the operator feel more comfortable when holding it and reducing the fatigue caused by long-term use.

[0020] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0021] In the present utility model, by setting a scraping plate assembly, after the servo motor is powered on, it starts to operate, and the transmission shaft at its output end rotates accordingly, driving the scraping plate to rotate synchronously. The scraping part on the scraping plate contacts the surface of the pipeline, and during the rotation process, it scrapes the surface of the pipeline to remove the rust on the surface. During the rust removal process, an external pump body device is connected to the internal screw hole on the surface of the assembly cover. Subsequently, the pump body device is started, and the rust remover or cleaning liquid is injected into the interior in a high-pressure state. Due to the design of the through holes on the scraping plate, the rust remover or cleaning liquid can be evenly distributed on the surface of the pipeline, ensuring the uniformity of the rust removal effect and avoiding local over-scraping or omission.

[0029] Next, in combination with the drawings and specific embodiments, the present utility model will be further described. It should be noted that on the premise of no conflict, any combination of the following described embodiments or technical features can form a new embodiment.

[0030] Embodiment:

[0031] Please combine Figures 1-5A shipbuilding pipeline rust removal device of this embodiment includes an assembly cover 1, a motor seat 2 is fixedly connected to the middle of the surface of the assembly cover 1, a scraper assembly 3 is arranged inside the motor seat 2, and operating handles 4 are fixedly connected to both sides of the surface of the assembly cover 1;

[0032] The scraper assembly 3 includes a servo motor 301, which is fixedly installed on the inner wall of the motor base 2 by bolts. The output end of the servo motor 301 is fixedly connected to a transmission shaft 302, and the outer surface of the transmission shaft 302 is fixedly connected to a scraper plate 303. The outer surface of the scraper plate 303 is provided with a plurality of flow holes 304. First, the operator starts the servo motor 301, and the servo motor 301 starts to run after being powered on, and the transmission shaft 302 at its output end rotates accordingly. The rotation of the transmission shaft 302 drives the scraper plate 303 fixed on its outer surface to rotate. The scraping part on the scraping plate 303 rotates synchronously and contacts with the surface of the pipe. The surface of the pipe is scraped during the rotation to remove the rust on the surface. During the rust removal process, the abrasive or cleaning liquid can be evenly sprayed onto the surface of the pipe to be treated through the flow hole 304, which can not only improve the rust removal effect, but also reduce the wear of the scraping plate 303 and extend its service life. Due to the design of the flow hole 304 on the scraping plate 303, the abrasive or cleaning liquid can be evenly distributed on the surface of the pipe, ensuring the uniformity of the rust removal effect and avoiding local excessive scraping or omission.

[0033] An inner screw hole 5 is provided on the surface of the assembly cover 1, and the internal thread connection of the inner screw hole 5 is provided with a plug 6. The operator threadably connects the interface of the external pump body equipment to the inner screw hole 5 on the surface of the assembly cover 1. The thread design of the inner screw hole 5 enables the pump body equipment to be firmly and tightly connected to the device. The operator starts the pump body equipment, and the rust remover or cleaning liquid is extracted from the pump body equipment by the action of the pump, and is injected into the device through the inner screw hole 5. After the liquid medium enters the device through the inner screw hole 5, it can be evenly distributed on the surface of the pipeline or flow through a specific channel to the flow hole 304 on the scraper plate 303, thereby covering the entire surface to be treated. The liquid medium is sprayed onto the pipeline surface under high pressure, and the mechanical scraping action of the scraper plate 303 can more effectively remove rust and dirt on the pipeline surface, thereby improving the rust removal and cleaning effects.

[0034] The outer surface of the assembly cover 1 is fixedly connected with fastening bolts 7 on all sides. The assembly cover 1 is fixedly installed with a flange 8 by the fastening bolts 7. The fastening bolts 7 are passed through the mounting holes 10 on the flange 8, and the flange 8 is fixed to the assembly cover 1 with nuts or other fasteners. By tightening the bolts, a stable connection is ensured between the flange 8 and the assembly cover 1. When equipment maintenance, overhaul or replacement of parts is required, the operator only needs to loosen and remove the fastening bolts 7 to easily remove the flange 8.

[0035] Inside the flange 8, the pipeline body 9 is fixedly connected. The assembly cover 1 is fixed on the flange 8 through the fastening bolts 7, so that the assembly cover 1 and the pipeline body 9 form an integral structure. In this way, the scraping component 3 can enter the pipeline interior through the assembly cover 1. Inside the pipeline, the scraping component 3 can directly contact the inner wall of the pipeline, and remove the rust and dirt on the inner wall through mechanical scraping. When it is necessary to clean, inspect or maintain the pipeline interior, the operator only needs to loosen and remove the fastening bolts 7, and then can easily disassemble the assembly cover 1 and the scraping component 3, so as to carry out subsequent cleaning and maintenance work on the interior of the pipeline after rust removal.

[0036] Mounting holes 10 are provided around the outer surface of the flange 8. The evenly distributed mounting holes 10 and the fastening bolts 7 can disperse the stress at the connection, avoiding connection failure or component damage caused by stress concentration.

[0037] The fastening bolts 7 are adapted to the mounting holes 10. The cooperation of the fastening bolts 7 and the mounting holes 10 can effectively fix the relative positions of the flange 8 and other components or the pipeline system, prevent displacement or loosening caused by external forces, and enhance the stability of the connection. When maintenance or disassembly is required, the flange 8 can be quickly separated by loosening the fastening bolts 7, which simplifies the disassembly process and improves the efficiency of maintenance work.

[0038] A rubber layer is provided on the outer surface of the operating handle 4. The outer surface of the operating handle 4 is wrapped with a layer of high-quality rubber material, which is known for its excellent softness and elasticity. By holding the operating handle 4, the operator can easily remove the assembly cover 1 from the pipeline, so as to avoid any impact on the normal flow and use of the pipeline when the rust removal device is not in use.

[0039] In the embodiment of this application, the implementation principle of a pipeline rust removal device for shipbuilding is as follows: First, the operator needs to firmly fix the assembly cover 1 on the flange 8 through the fastening bolts 7 to ensure that the assembly cover 1 is tightly combined with the pipeline body 9 to form a stable integrated structure, so that the scraper assembly 3 can smoothly enter the interior of the pipeline. Next, the operator needs to start the servo motor 301 located inside the motor base 2. With the start of the motor, it drives the scraping plate 303 to rotate at high speed through the transmission shaft 302. During the rotation process, the scraping plate 303 closely contacts the inner surface of the pipeline and uses its specially designed scraping part to perform efficient mechanical scraping on the pipeline surface. This process aims to thoroughly remove the accumulated rust and dirt on the pipeline surface. To further enhance the rust removal and cleaning effects, the operator needs to connect an external pump device to the internal thread hole 5 on the surface of the assembly cover 1. Subsequently, start the pump device to inject the rust remover or cleaning liquid into the device in a high-pressure state. After the liquid medium enters the device through the internal thread hole 5, it can be evenly distributed on the pipeline surface or flow to the through holes 304 on the scraping plate 303, thus ensuring that the entire surface to be treated is completely covered. The combination of the spraying of the liquid medium under high pressure and the mechanical scraping action of the scraping plate 303 can significantly improve the efficiency of removing rust and dirt on the pipeline surface and ensure the high-quality completion of the rust removal and cleaning work.

[0040] The above-mentioned implementation manners are only the preferred implementation manners of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention fall within the scope of protection required by the present invention.
