Description

Technical Field

[0001] This utility model relates to the field of hydraulic cylinder cleaning technology, and in particular to a long-stroke hydraulic cylinder cleaning assembly. Background Technology

[0002] Cleaning long-stroke hydraulic cylinders is crucial in the maintenance of hydraulic systems. Long-stroke hydraulic cylinders are widely used in various industrial equipment, such as large cranes, hydraulic presses, and tunnel boring machines. Due to their complex working environment, oil, impurities, and rust easily accumulate inside the cylinders. This not only reduces cylinder efficiency but can also cause equipment failure and shorten equipment lifespan. Therefore, developing efficient and reliable cleaning components for long-stroke hydraulic cylinders has become a key requirement for ensuring stable operation of hydraulic systems and improving industrial production efficiency.

[0003] Currently, common methods for cleaning long-stroke hydraulic cylinders mainly involve using simple handheld cleaning tools or placing the cleaning device directly inside the cylinder. Handheld cleaning tools typically require the operator to manually control the nozzle to spray cleaning fluid into the cylinder, relying on experience and skill to achieve the cleaning. Directly placed cleaning devices often use a simple fixing method, placing the cleaning nozzle and other components inside the cylinder and utilizing the pressure of the cleaning fluid for flushing. These existing technologies have relatively simple mechanical structures, and their technical principles focus on basic cleaning fluid spraying, lacking effective control over the stability and precision of the cleaning process.

[0004] However, these existing cleaning methods have significant drawbacks. When cleaning the inside of the hydraulic cylinder, whether using a handheld cleaning tool or placing the cleaning device directly, shaking is highly likely. When using a handheld cleaning tool, operators find it difficult to maintain a stable posture for extended periods. As cleaning time increases, hand fatigue exacerbates the shaking, resulting in uneven spraying of the cleaning fluid and ineffective cleaning of the cylinder's inner wall. Directly placed cleaning devices, lacking reliable fixing methods, are easily displaced and shaken inside the cylinder due to the reaction force of the cleaning fluid and the cylinder's own structure. This not only reduces the cleaning effect but also causes unnecessary damage to the cylinder's inner wall, failing to meet the stringent stability requirements of long-stroke hydraulic cylinders. Therefore, a long-stroke hydraulic cylinder cleaning assembly is proposed to address these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a long-stroke hydraulic cylinder cleaning assembly, which aims to improve the problem that the existing technology cannot easily keep the base stable.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A long-stroke hydraulic cylinder cleaning assembly includes a fixed base, a placement hole inside the fixed base, a stabilizing component inside the fixed base, a water pipe inside the fixed base, a fixing column on the outer wall of the water pipe, a nozzle fixedly connected to one end of the fixing column, a cleaning component on the outer wall of the fixing column, and a moving component inside the fixed base.

[0008] The stabilizing component includes a hydraulic rod, the outer wall of which is fixedly connected to the inside of the fixed base, a connecting column fixedly connected to the output end of the hydraulic rod, the outer wall of which is slidably connected to the inside of the fixed base, and a rubber pad fixedly connected to one end of the connecting column.

[0009] As a further description of the above technical solution:

[0010] The movable component includes a movable plate, which is fixedly connected to the outer wall of the fixed column. A threaded rod is threadedly connected to the inside of the movable plate. The outer wall of the threaded rod is rotatably connected to the inside of the fixed seat. A knob is fixedly connected to the other end of the threaded rod. A limit rod is fixedly connected to the outer wall of the fixed seat. The limit rod is disposed inside the movable plate.

[0011] As a further description of the above technical solution:

[0012] The cleaning assembly includes a fixing ring, which is internally fixedly connected to the outer wall of the fixing post;

[0013] As a further description of the above technical solution:

[0014] The fixed ring has a slot inside, and a connecting ring is slidably connected to the outer wall of the fixed ring. A scraper is fixedly connected to the outer wall of the connecting ring.

[0015] As a further description of the above technical solution:

[0016] The connecting ring has a limiting groove inside, and a sliding column is slidably connected inside the connecting ring;

[0017] As a further description of the above technical solution:

[0018] One end of the sliding column is fixedly connected to a retaining ball, and the outer wall of the retaining ball is slidably connected to the inside of the retaining groove.

[0019] As a further description of the above technical solution:

[0020] The other end of the sliding column is fixedly connected to a limiting disk, and the outer wall of the limiting disk is slidably connected inside the limiting groove.

[0021] As a further description of the above technical solution:

[0022] A spring is provided inside the connecting ring. One end of the spring is fixedly connected to the inner wall of the limiting groove, and the other end of the spring is fixedly connected to the other end of the limiting disc.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, by activating the hydraulic rod, the connecting column is moved inside the fixed seat, thereby pushing the rubber pad to move, so that the fixed seat can be fixed at the hydraulic cylinder port, achieving stable fixation of the fixed seat, thus ensuring stable cleaning of the interior and facilitating its operation. This solves the problem of shaking when cleaning the interior by hand or by placing it directly, and improves the stability of cleaning.

[0025] 2. In this utility model, the ball moves by means of a movable connecting ring. When the connecting ring moves, the ball slides inside the slot by means of the driving force of the connecting ring on the sliding column and the limiting disc, and in conjunction with the spring. This allows for easy disassembly and assembly of the scraper, and placement of scrapers of different specifications for cleaning. This solves the problem of not being able to easily adjust according to different hydraulic cylinders and improves the ease of disassembly and assembly. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a long-stroke hydraulic cylinder cleaning assembly, including a fixed base 1. The fixed base 1 is made of high-strength alloy steel, which is hard and corrosion-resistant, and can be used stably for a long time in complex working environments. The fixed base 1 has a placement hole 12 inside, which is a regular cylinder with precisely designed dimensions to provide accurate positioning and stable support for various components to be installed later. The fixed base 1 is equipped with a stabilizing component and a water pipe 2 inside. The water pipe 2 is made of corrosion-resistant engineering plastic, which has good flexibility and sealing performance to ensure stable delivery of cleaning fluid. The outer wall of the water pipe 2 is equipped with a fixing column 5, and a nozzle 6 is fixedly connected to one end of the fixing column 5. The outer wall of the fixing column 5 is equipped with a cleaning component, and the fixed base 1 is equipped with a moving component.

[0033] The stabilizing component includes a hydraulic rod 11, made of high-quality stainless steel, which not only has good rust resistance but can also withstand significant pressure. The hydraulic rod 11 is securely fixed to a pre-set mounting slot inside the mounting base 1 using a high-strength welding process. The outer wall of the hydraulic rod 11 is fixedly connected to the inside of the mounting base 1. A connecting column 10 is fixedly connected to the output end of the hydraulic rod 11. The connecting column 10 is made of solid aluminum alloy, which is lightweight yet high-strength. Its outer wall is finely polished to form a precise sliding connection with the guide groove inside the mounting base 1, ensuring smooth and stable movement. The outer wall of the connecting column 10 is slidably connected to the inside of the mounting base 1. A rubber pad 9 is fixedly connected to one end of the connecting column 10. The rubber pad 9 is made of highly elastic and highly wear-resistant nitrile rubber, and its surface is designed with unique anti-slip textures to ensure proper contact with the cylinder bore. Upon contact, a strong frictional force is generated, thereby firmly fixing the fixed seat 1 at the cylinder port position. The moving component includes a moving plate 13, which is internally fixedly connected to the outer wall of the fixed column 5. A threaded rod 7 is threadedly connected inside the moving plate 13. The threaded rod 7 is made of high-quality alloy steel and has undergone heat treatment, giving it good strength and toughness. Its outer wall is flexibly rotatably connected to the inside of the fixed seat 1 through a high-precision bearing. The outer wall of the threaded rod 7 is rotatably connected to the inside of the fixed seat 1. A knob 3 is fixedly connected to the other end of the threaded rod 7. The surface of the knob 3 is designed with anti-slip texture to facilitate manual rotation by the operator. A limit rod 8 is fixedly connected to the outer wall of the fixed seat 1 and is located inside the moving plate 13.

[0034] Specifically, when cleaning a long-stroke hydraulic cylinder, the first step is to select a matching threaded rod 7 based on the actual length of the cylinder. Then, the carefully selected threaded rod 7 is placed smoothly into the specific mounting slot inside the fixed seat 1. Simultaneously, the moving plate 13 is accurately fitted onto the outer wall of the threaded rod 7 and the limiting rod 8. After completing these preparations, the fixed seat 1 is precisely placed at the cylinder opening of the hydraulic cylinder. Next, the hydraulic rod 11 inside the fixed seat 1 is activated. The hydraulic rod 11 begins to work, its piston rod extends, and thus drives the connecting column 10 to move smoothly along a predetermined track inside the fixed seat 1. During the movement of the connecting column 10, the connected rubber pad 9 also moves forward. When the rubber pad 9 is tightly pressed against the inner wall of the cylinder opening, sufficient friction is generated, successfully fixing the fixed seat 1 firmly in the cylinder opening position. At this time, turning the knob 3 activates the transmission structure between the knob 3 and the threaded rod 7, causing the threaded rod 7 to rotate. As the threaded rod 7 rotates, the movable plate 13, which is threaded with it, slides smoothly on the outer wall of the limiting rod 8. The nozzle 6 is installed on the movable plate 13, thereby enabling the nozzle 6 to move inside the oil cylinder and continuously spray water evenly and efficiently to clean the inside of the oil cylinder, ensuring that all parts of the oil cylinder are thoroughly cleaned.

[0035] Reference Figure 1 and Figure 3The cleaning components include a fixed ring 15, which is internally fixed to the outer wall of the fixed column 5. The fixed ring 15 is forged from high-strength stainless steel, possessing a hard texture and excellent corrosion resistance, effectively resisting the erosion of cleaning fluid and the complex environment inside the cylinder. The fixed ring 15 is firmly fixed to the outer wall of the fixed column 5 through a precision welding process, ensuring a stable connection throughout the cleaning process. A slot 16 is provided inside the fixed ring 15, and a connecting ring 14 is slidably connected to its outer wall. A scraper 4 is fixedly connected to the outer wall of the connecting ring 14. The scraper 4 is made of high-hardness, wear-resistant polyurethane rubber, and its scraping surface is designed with a special serrated texture, which can more effectively scrape away dirt adhering to the inner wall of the cylinder. A limiting groove 18 is provided inside the connecting ring 14. The limiting groove 18 is a slender cylindrical channel with smooth walls and a certain degree of roughness to ensure... The limiting disc 19 and the sliding column 20 slide flexibly and stably within the ring 14. The sliding column 20 is slidably connected inside the ring 14. One end of the sliding column 20 is fixedly connected to a ball 21. The outer wall of the ball 21 is slidably connected inside the groove 16. The other end of the sliding column 20 is fixedly connected to the limiting disc 19. The limiting disc 19 is made of stainless steel. Its outer wall forms a precise sliding fit with the inside of the limiting groove 18. The outer wall of the limiting disc 19 is slidably connected inside the limiting groove 18. A spring 17 is provided inside the ring 14. One end of the spring 17 is fixedly connected to the inner wall of the limiting groove 18, and the other end of the spring 17 is fixedly connected to the other end of the limiting disc 19.

[0036] Specifically, before officially starting the cleaning work on the long-stroke hydraulic cylinder, the specific dimensions inside the cylinder must be fully considered. At this time, the connecting ring 14 is carefully placed on the outer wall of the fixed ring 15. Due to the special design of the contact area between the connecting ring 14 and the retaining ball 21, the retaining ball 21 is arc-shaped. As the connecting ring 14 gradually approaches the fixed ring 15, it exerts a squeezing force on the retaining ball 21, thereby pushing the retaining ball 21 to move. The movement of the retaining ball 21 further drives the sliding column 20 to move synchronously, and the displacement of the sliding column 20 pushes the limiting disc 19 to move smoothly inside the limiting groove 18. During this process, the limiting disc 19 compresses the spring 17. When it moves to a suitable position that fits the internal dimensions of the cylinder, the connecting ring 14 is released. At this time, the spring 17 quickly rebounds, causing the retaining ball 21 to slide into the retaining groove 16, successfully and firmly fixing the connecting ring 14 to the outer wall of the fixed ring 15. Then, the scraper 4 installed on the connecting ring 14 can be used to efficiently scrape the inner wall of the cylinder, effectively removing the dirt attached to the inner wall of the cylinder.

[0037] Working principle: When cleaning a long-stroke hydraulic cylinder, place the threaded rod 7 of the corresponding length inside the fixed seat 1, and place the moving plate 13 on the outer wall of the threaded rod 7 and the limit rod 8. Then place the fixed seat 1 at the cylinder opening, start the internal hydraulic rod 11, and drive the connecting column 10 to move inside the fixed seat 1. Then, drive the rubber pad 9 to move through the connecting column 10, and fix the fixed seat 1 at the cylinder opening. Then, turn the knob 3, and drive the threaded rod 7 to rotate, thereby driving the moving plate 13 to slide on the outer wall of the limit rod 8, driving the nozzle 6 to move and spray water to clean the inside of the cylinder.

[0038] In addition, before cleaning, the connecting ring 14 can be placed on the outer wall of the fixed ring 15 according to the internal size of the oil cylinder. Since the ball 21 in contact with it is arc-shaped, it will push the ball 21 to move. Then, the ball 21 will drive the sliding column 20 to move, and then push the limiting disc 19 to move inside the limiting groove 18 and compress the spring 17 to the appropriate position. The spring 17 will rebound and drive the ball 21 to slide into the groove 16, fixing it on the outer wall of the fixed ring 15, and scraping the inner wall of the oil cylinder.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
