Description

Technical Field

[0001] This utility model relates to the field of hydraulic cylinder technology, and in particular to a corrosion-resistant open-body mud barge cylinder. Background Technology

[0002] Corrosion-resistant open-body mud barge cylinders are mainly used in the fields of liquid storage and transportation, especially in marine environments. Their background technology includes the use of high-strength anti-corrosion coatings, special metal alloy materials, and innovative designs to ensure that the cylinders are not affected by corrosion when exposed to water, chemicals, and salt spray for a long time, thereby extending their service life and reducing maintenance costs.

[0003] However, in actual use, the following shortcomings still exist. For example, the existing open-body mud barge cylinders cannot achieve the effects of improving the cylinder's corrosion resistance and sealing performance, reducing failures and extending service life. Ordinary steel or unoptimized cylinder bodies are prone to uniform corrosion, pitting corrosion or crevice corrosion when in contact with corrosive media such as seawater and mud for a long time, resulting in thinning of the cylinder wall, decrease in strength, and even perforation and leakage. The traditional piston rod surface protection is insufficient, and it is prone to rust in humid and salt spray environments. The wear is aggravated when it rubs against the inner wall of the cylinder, and the increased surface roughness further accelerates corrosion. Cylinders that have not been optimized for corrosion resistance may experience serious corrosion or leakage in only 1 to 2 years in harsh environments, which is far below the design expectation.

[0004] Therefore, this utility model proposes a corrosion-resistant open-body mud barge cylinder to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and propose a corrosion-resistant open-body mud barge cylinder.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a corrosion-resistant open-body mud barge cylinder, comprising a cylinder body and a piston rod disposed on the cylinder body, and further comprising:

[0007] The anti-corrosion component includes a first housing disposed on the cylinder body, a second housing disposed on the other side of the first housing, both the first and second housings being provided with an anti-corrosion coating, both the first and second housings being provided with a slot, both the first and second housings being connected with a block disposed in the slot, both the first and second housings being connected with an injection port, both the first and second housings being provided with a spiral guide groove, the injection port communicating with the spiral guide groove, and the piston rod being provided with a ceramic coating.

[0008] A sealing assembly, comprising a first housing and a protective cover connected to a second housing, wherein a limiting ring is connected to the protective cover and a second sealing ring is connected to the limiting ring.

[0009] Furthermore, a first fixing block is connected to the cylinder body, and a second fixing block is connected to the side of the first housing and the second housing near the first fixing block.

[0010] The beneficial effect of adopting the above-mentioned further solution is that the first fixing block on the cylinder body is connected to the first housing and the second fixing block on the second housing by bolts.

[0011] Furthermore, the first fixing block is threaded with a bolt, which is threaded onto the second fixing block.

[0012] The beneficial effect of adopting the above-mentioned further solution is that when the bolts are tightened, the first housing and the second housing fit tightly against the cylinder body to form a stable connection, ensuring that the anti-corrosion components will not loosen when the cylinder is working, and ensuring the continuous effectiveness of the anti-corrosion function.

[0013] Furthermore, both the first housing and the second housing are connected with a first sealing ring.

[0014] The beneficial effects of adopting the above-mentioned further solution are as follows: the first sealing ring in the first housing and the second housing is installed on the contact surface between the housing and the cylinder body. When the housing is fixed to the cylinder body by bolts, the first sealing ring is squeezed and undergoes elastic deformation, filling the tiny gap between the housing and the cylinder body, preventing the anti-corrosion liquid from leaking from the connection, and enhancing the sealing performance of the anti-corrosion component.

[0015] Furthermore, a telescopic spring is provided inside the protective cover.

[0016] The beneficial effects of adopting the above-mentioned further solution are: the telescopic spring is built into the protective cover, providing continuous rebound force, so that the protective cover is always in close contact with the edge of the cylinder body, the telescopic spring automatically adjusts the position of the protective cover, preventing mud, sand, salt spray and other substances from directly contacting the surface of the cylinder body, reducing mechanical wear and extending the service life of the cylinder.

[0017] Furthermore, a wear-resistant ring is connected to the limiting ring.

[0018] The beneficial effects of adopting the above-mentioned further solution are: the wear-resistant ring connected to the limiting ring withstands friction, and its high wear resistance can reduce its own wear, extend the service life of related components, and ensure the long-term stable operation of the sealing assembly.

[0019] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0020] In this invention, the anti-corrosion component consists of a first housing and a second housing connected to the cylinder body via a locking block and a locking groove. The anti-corrosion coating on the surface of the housing can resist external corrosion. After the anti-corrosion liquid is injected from the injection port, the liquid flows along the spiral guide groove and forms a protective film on the cylinder body. The ceramic coating on the piston rod enhances its own anti-corrosion ability. In the sealing component, the protective cover and the limiting ring form multiple barriers to prevent the intrusion of mud and sand. The second sealing ring adapts to deformation under high pressure to ensure zero leakage. This invention achieves the effects of improving the corrosion resistance of the cylinder, ensuring good sealing performance, reducing failures, and extending service life.

[0030] 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.

[0031] like Figures 1-5 As shown, this embodiment provides a technical solution: a corrosion-resistant open-body mud barge cylinder, including a cylinder body 1 and a piston rod 2 disposed on the cylinder body 1, and further including:

[0032] The anti-corrosion component 3 includes a first housing 31 disposed on the cylinder body 1, a second housing 32 disposed on the other side of the first housing 31, an anti-corrosion coating 33 disposed on both the first housing 31 and the second housing 32, a slot 34 provided on both the first housing 31 and the second housing 32, a block 35 connected to both the first housing 31 and the second housing 32, the block 35 disposed in the slot 34, an injection port 36 connected to both the first housing 31 and the second housing 32, a spiral guide groove 37 provided in both the first housing 31 and the second housing 32, the injection port 36 communicating with the spiral guide groove 37, and a ceramic coating 38 disposed on the piston rod 2.

[0033] The sealing assembly 4 includes a protective cover 42 connected to both the first housing 31 and the second housing 32. A limit ring 44 is connected to the protective cover 42, and a second sealing ring 46 is connected to the limit ring 44. In the anti-corrosion assembly 3, the first housing 31 and the second housing 32 are spliced ​​to the outside of the cylinder body 1 by a locking block 35 and a locking groove 34. The anti-corrosion coating 33 on their surfaces can resist external corrosion. After the anti-corrosion liquid is injected from the injection port 36, the liquid flows along the spiral guide groove 37 and forms a protective film on the outside of the cylinder body 1. The ceramic coating 38 on the piston rod 2 enhances its own anti-corrosion ability. In the sealing assembly 4, the protective cover 42 and the limit ring 44 form multiple barriers to prevent the intrusion of mud and sand. The second sealing ring 46 adapts to deformation under high pressure to ensure zero leakage. This achieves the effect of improving the corrosion resistance of the cylinder and good sealing performance, reducing failures and extending service life.

[0034] The above solutions also have the problem that the open-body mud barge cylinder cannot reduce mechanical wear during use, such as... Figures 1-4As shown: A first fixing block 39 is connected to the cylinder body 1. A second fixing block 310 is connected to the side of the first housing 31 and the second housing 32 near the first fixing block 39. The first fixing block 39 on the cylinder body 1 is connected to the second fixing block 310 on the first housing 31 and the second housing 32 by bolts 311. The first fixing block 39 is threaded with bolts 311, and the bolts 311 are threaded to the second fixing block 310. When the bolts 311 are tightened, the first housing 31 and the second housing 32 are tightly fitted to the cylinder body 1 to form a stable connection, ensuring that the anti-corrosion component 3 will not loosen when the cylinder is working, and ensuring the continuous effectiveness of the anti-corrosion function.

[0035] like Figure 1 as well as Figures 3-5 As shown, both the first housing 31 and the second housing 32 are connected to a first sealing ring 41. The first sealing ring 41 in the first housing 31 and the second housing 32 is installed on the contact surface between the housing and the cylinder body 1. When the housing is fixed to the cylinder body 1 by bolts 311, the first sealing ring 41 is squeezed and undergoes elastic deformation, filling the tiny gap between the housing and the cylinder body 1, preventing the anti-corrosion liquid from leaking from the connection, and enhancing the sealing performance of the anti-corrosion component 3. A telescopic spring 43 is provided inside the protective cover 42. The telescopic spring 43 is built into the protective cover 42 and provides continuous rebound force, so that the protective cover 42 is always in close contact with the edge of the cylinder body 1. The telescopic spring 43 automatically adjusts the position of the protective cover 42 to prevent mud, sand, salt spray and other substances from directly contacting the surface of the cylinder body 1, reducing mechanical wear and extending the service life of the cylinder. A wear-resistant ring 45 is connected to the limiting ring 44. The wear-resistant ring 45 connected to the limiting ring 44 withstands friction. Its high wear resistance can reduce its own wear, extend the service life of related components, and ensure the long-term stable operation of the sealing component 4.

[0036] Working principle:

[0037] like Figures 1-5As shown, firstly, in the anti-corrosion component 3, the first housing 31 and the second housing 32 are spliced ​​to the outside of the cylinder body 1 by means of a locking block 35 embedded in the locking groove 34. Then, the first fixing block 39 on the cylinder body 1 and the second fixing block 310 on the housing are tightened by bolts 311, so that the housing fits tightly against the cylinder body 1, forming a stable installation base. The anti-corrosion coating 33 on the surface of the housing can directly resist the erosion of external corrosive media. The anti-corrosion liquid injected from the injection port 36 will flow along the spiral guide groove 37 inside the housing, forming a continuous protective film on the outside of the cylinder body 1, further isolating the corrosion source. At the same time, the ceramic coating 38 on the surface of the piston rod 2 enhances the corrosion resistance of the piston rod 2 itself due to its high chemical stability. The protective cover 42 of the sealing component 4 is installed on the first housing 31 and the second housing 32, and the internal telescopic spring 43 The continuous rebound force ensures that the protective cover 42 always fits tightly against the edge of the cylinder body 1. The telescopic spring 43 can automatically adjust the position of the protective cover 42, forming the first physical barrier to effectively block the intrusion of impurities such as mud, sand, and salt spray. The wear-resistant ring 45 on the limiting ring 44 can withstand friction, reduce its own wear, and ensure the stable operation of the limiting ring 44. The second sealing ring 46 on the limiting ring 44 can adaptively deform under high pressure, tightly filling the gaps between each contact surface to achieve a leak-proof sealing effect. In addition, the first sealing ring 41 in the first housing 31 and the second housing 32 is squeezed and deformed when the housing is fixed, filling the tiny gap between the housing and the cylinder body 1 to prevent the leakage of anti-corrosion liquid, further enhancing the sealing performance of the anti-corrosion component 3. The corrosion resistance of the cylinder is significantly improved, the sealing performance is good, thereby reducing the occurrence of failures and extending the service life.

[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
