Description

Technical Field

[0001] This invention relates to the field of steel structure technology, specifically to a steel structure with rust prevention function. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. The structure is mainly composed of components such as beams, steel columns, and steel trusses made of steel sections and steel plates. Rust removal and prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing are used. Steel structures are prone to rust, so they generally need to be rust-removed, galvanized or painted, and require regular maintenance.

[0003] The existing method for rust prevention and maintenance of steel structures is to apply rust-preventive oil to the outside of the steel structure to form a stable rust-preventive coating, which isolates the steel structure from the outside air and prevents the steel structure from rusting. However, the use of rust-preventive oil has a shelf life. After a period of time, when the rust-preventive coating fails, it is necessary to reapply rust-preventive oil for maintenance.

[0004] However, in actual use, the above-mentioned methods often involve repeatedly applying the rust-preventive oil evenly with a brush. Due to the limited contact area of ​​the brush, it often takes a long time to apply it evenly. During the application process, excess rust-preventive oil drips onto the bottom, resulting in waste. However, this operation is necessary to ensure even application. Therefore, we propose a steel structure with rust-preventive function. Summary of the Invention

[0005] The purpose of this invention is to provide a steel structure with rust prevention function to solve the problems mentioned in the background art.

[0007] The mounting cylinder is fixedly installed on the upper surface of the mounting base. The mounting cylinder is sleeved on the outside of the steel structure body. The cavity between the mounting cylinder and the steel structure body forms a liquid storage cavity, which can store and reuse rust-preventive oil. The inside of the liquid storage cavity is provided with an annular screen, which can filter impurities in the rust-preventive oil. The upper surface of the mounting cylinder is provided with a mounting groove.

[0008] A movable groove is formed on the inner wall surface of the mounting cylinder, and a slider is slidably connected inside the movable groove. A return spring is fixedly installed on the bottom surface of the slider.

[0009] A movable cylinder is sleeved on the outside of the steel structure body. A sponge is fixedly installed on the inner wall surface of the movable cylinder. The sponge can absorb the anti-rust oil for easy application. An annular filter screen is fixedly installed at the bottom of the movable cylinder to prevent impurities from adhering to the bottom of the sponge.

[0010] A fixed column is fixedly installed on the outside of the movable cylinder. A handle is fixedly installed on the surface of the fixed column away from the steel structure body. Pulling the handle can drive the movable cylinder to move synchronously through the fixed column.

[0011] Preferably, the side surface of the slider near the annular screen is fixedly connected to the side wall of the annular screen, and the outer wall of the annular screen is in contact with the inner wall of the mounting cylinder.

[0012] Preferably, the size of the mounting slot is adapted to the size of the fixing column, and the mounting slot can be used to store the fixing column.

[0013] Preferably, the outer wall of the sponge is in contact with the outer wall of the steel structure body, and the sponge can coat the outer wall of the steel structure body when it moves up and down.

[0014] Preferably, the fixing mechanism includes:

[0015] A through hole is formed on the upper surface of the movable cylinder;

[0016] A limiting post is fixedly installed on the bottom surface of the waterproof tray. A limiting groove is formed on the side of the limiting post away from the steel structure body. A limiting spring is fixedly installed on the side of the limiting groove close to the steel structure body. A limiting block is fixedly installed on the end of the limiting spring away from the steel structure body. Through the cooperation of the through hole, limiting post, limiting groove, limiting spring and limiting block, the moving cylinder can be limited.

[0017] Preferably, the size of the limiting post is adapted to the size of the through hole.

[0018] Preferably, the sealing mechanism includes:

[0019] A sealing plate is hinged to the upper surface of the mounting cylinder. A waterproof rubber layer is fixedly installed on the side of the sealing plate near the steel structure body. The sealing plate and the waterproof rubber layer can seal the inside of the liquid storage cavity.

[0020] A pull frame is fixedly installed on the upper surface of the sealing plate. Moving the pull frame can drive the sealing plate to rotate.

[0021] Preferably, a drain hole is provided on the left side surface of the mounting cylinder, and a rubber plug is fitted inside the drain hole.

[0023] Compared with the prior art, the present invention provides a steel structure with rust prevention function, which has the following characteristics:

[0024] Beneficial effects:

[0025] 1. This rust-preventive steel structure uses a system where rust-preventive oil is poured into the storage chamber, saturating the sponge. Pulling the handle upwards engages the fixed column, moving the cylinder and sponge upwards to apply the rust-preventive oil to the steel structure. The circular sponge quickly and evenly coats the surface of the steel structure after one back-and-forth motion, making it easy to use. After application, the cylinder is placed on top of the steel structure to prevent excess oil from dripping onto the outside. Excess oil flows downwards back into the storage chamber for collection. A ring-shaped screen filters impurities from the dripping oil, facilitating later cleaning. The cylinder is then returned to the storage chamber for storage. The ring-shaped filter prevents impurities from adhering to the bottom of the sponge and affecting subsequent maintenance. The system is simple to operate and allows for multiple uses of the rust-preventive oil, avoiding waste.

[0026] 2. The steel structure with rust prevention function can limit the movement of the cylinder through the combination of through holes, limiting posts, limiting grooves, limiting springs and limiting blocks, so as to avoid the fatigue caused by the user having to lift the cylinder for a long time while waiting for excess rust-preventive oil to drip.

[0027] 3. The steel structure with rust prevention function can seal the inside of the liquid storage chamber through the set sealing plate and waterproof rubber layer, so as to avoid external factors from contaminating the rust-preventive oil during the storage of the moving cylinder and sponge. At the same time, after the rust-preventive oil has been used for a long time, the rubber plug can be pulled out to open the drain hole to replace the rust-preventive oil, which is easy to operate.

[0037] like Figures 1-8 As shown, the present invention provides a technical solution: a steel structure with anti-rust function, including a mounting base 1, a steel structure body 2 fixedly mounted on the upper surface of the mounting base 1, a waterproof tray 3 fixedly mounted on the upper surface of the steel structure body 2, a drainage groove opened on the top of the waterproof tray 3, the drainage groove can drain rainwater to reduce the impact of rainwater on the steel structure body 2, an anti-rust maintenance mechanism 4 is provided above the mounting base 1, a fixing mechanism 5 is provided below the waterproof tray 3, and a sealing mechanism 6 is provided inside the anti-rust maintenance mechanism 4.

[0038] The rust prevention and maintenance mechanism 4 includes: an installation cylinder 401, a moving groove 403, a moving cylinder 407, and a fixed column 410. The installation cylinder 401 is fixedly installed on the upper surface of the installation base 1. The installation cylinder 401 is sleeved on the outside of the steel structure body 2. The cavity between the installation cylinder 401 and the steel structure body 2 forms a liquid storage chamber 402, into which rust-preventive oil can be added for storage. An annular screen 406 is provided inside the liquid storage chamber 402. The annular screen 406 can filter the flowing rust-preventive oil and filter dust, debris, and other impurities above the annular screen 406 for easy cleaning.

[0039] The side surface of the slider 405 near the annular screen 406 is fixedly connected to the side wall of the annular screen 406. The outer wall of the annular screen 406 fits against the inner wall of the mounting cylinder 401. The upper surface of the mounting cylinder 401 is provided with a mounting groove 412, the size of which is adapted to the size of the fixed column 410. The fixed column 410 can be placed inside the mounting groove 412. Two movable grooves 403 are provided on the inner wall surface of the mounting cylinder 401. The two movable grooves 403 are respectively provided on the mounting cylinder 401. On the inner wall surfaces of the left and right sides of the cylinder 401, sliders 405 are slidably connected inside the moving grooves 403. A return spring 404 is fixedly installed on the bottom surface of the sliders 405. The side walls of the two sliders 405 corresponding to the two moving grooves 403 are fixedly connected to the side walls of the annular screen 406. When the annular screen 406 is subjected to a force and moves downward, it will drive the sliders 405 to press the return spring 404 downward to generate elastic potential energy. After the external force disappears, the annular screen 406 will move upward and reset under the action of the elastic potential energy of the return spring 404.

[0040] The movable cylinder 407 is fitted onto the outside of the steel structure body 2. A sponge 408 is fixedly installed on the inner wall surface of the movable cylinder 407. The sponge 408 can absorb rust-preventive oil. When the sponge 408 moves up and down, the rust-preventive oil absorbed inside is applied to the surface of the steel structure body 2 to achieve a rust-preventive effect. The circular sponge 408 can quickly and evenly coat the surface of the steel structure body 2 after moving up and down once. It is easy to use. The outer wall of the sponge 408 fits in close contact with the outer wall of the steel structure body 2. The bottom of the movable cylinder 407 is fixed. An annular filter screen 409 is installed to prevent impurities in the anti-rust oil inside the liquid storage chamber 402 from adhering to the bottom surface of the sponge 408 and returning to the surface of the steel structure body 2 during the application of anti-rust oil, thus affecting the anti-rust effect of the anti-rust oil. The fixing post 410 is fixedly installed on the outside of the moving cylinder 407. A handle 411 is fixedly installed on the side of the fixing post 410 away from the steel structure body 2. By pulling the handle 411, the sponge 408 and the moving cylinder 407 can be moved up and down for application via the fixing post 410.

[0041] The fixing mechanism 5 includes a through hole 501 and a limiting post 502. The through hole 501 is opened on the upper surface of the moving cylinder 407. The limiting post 502 is fixedly installed on the bottom surface of the waterproof plate 3. The size of the limiting post 502 is adapted to the size of the through hole 501. When the moving cylinder 407 moves upward, the through hole 501 is aligned with the limiting post 502 and inserted. A limiting groove 503 is opened on the side surface of the limiting post 502 away from the steel structure body 2. A limiting spring 504 is fixedly installed on the side surface of the limiting groove 503 close to the steel structure body 2. A limiting block 505 is fixedly installed on the end of the limiting spring 504 away from the steel structure body 2.

[0042] Furthermore, during the process of the limiting post 502 being inserted into the through hole 501, the limiting block 505 will be squeezed into the limiting groove 503 and the limiting spring 504 will be compressed to generate elastic potential energy. After the moving cylinder 407 moves above the limiting block 505, the limiting block 505 will move outward and pop out under the action of the elastic potential energy of the limiting spring 504, limiting the moving cylinder 407 so that the bottom of the moving cylinder 407 is suspended. At this time, the excess anti-rust oil applied to the outer wall surface of the steel structure body 2 will flow downward into the liquid storage chamber 402 for collection again, which can effectively avoid the fatigue caused by the user having to hold the moving cylinder 407 for too long.

[0043] The sealing mechanism 6 includes a sealing plate 603 and a pull frame 605. The sealing plate 603 is hinged to the upper surface of the mounting cylinder 401. There are two sealing plates 603. When the two sealing plates 603 close towards the steel structure body 2, they seal the inside of the liquid storage cavity 402 to prevent external factors from contaminating the anti-rust oil. A waterproof rubber layer 604 is fixedly installed on the side of the sealing plate 603 closest to the steel structure body 2. The inner wall of the waterproof rubber layer 604 is in contact with the outer wall of the steel structure body 2. The waterproof rubber layer 604 can further enhance the sealing effect. The pull frame 605 is fixedly installed on the upper surface of the sealing plate 603. Rotating the pull frame 605 can drive the sealing plate 603 to flip open or close. A drain hole 601 is provided on the left side surface of the mounting cylinder 401. A rubber plug 602 is fitted inside the drain hole 601. Pulling out the rubber plug 602 can open the drain hole 601 to drain the anti-rust oil in the liquid storage chamber 402 that needs to be replaced after long-term use, so as to facilitate the addition of new anti-rust oil.

[0044] In this invention, during use, rust-preventive oil is added to the inside of the liquid storage chamber 402, not exceeding the bottom surface of the annular screen 406. The moving cylinder 407 is pressed downwards to allow the sponge 408 to absorb the rust-preventive oil. Pulling the pull brackets 605 on both sides causes the sealing plate 603 to flip and open the liquid storage chamber 402. Pulling the handle 411 upwards causes the moving cylinder 407 and the sponge 408, fully soaked in rust-preventive oil, to move upwards via the fixed column 410, applying rust-preventive oil to the outer side of the steel structure body 2. The circular sponge 408, after moving up and down once, can quickly and evenly coat the surface of the steel structure body 2, making it convenient to use. After coating, the through hole 501 is... The movable cylinder 407 is fixed in place by the alignment of the limiting post 502, the limiting groove 503, the limiting spring 504, and the limiting block 505, thus suspending it. This allows excess rust-preventive oil applied to the outer surface of the steel structure body 2 to flow downwards into the storage chamber 402 for collection. This prevents the movable cylinder 407 and sponge 408 from obstructing the dripping of the rust-preventive oil. The annular screen 406 filters the rust-preventive oil, trapping impurities above it for easy cleaning later. After the rust-preventive oil has dripped completely, the limiting block 505 can be pushed inwards to release the limitation on the movable cylinder 407. Remove the movable cylinder 407 and align the fixed post 410 with the mounting slot 412. The movable cylinder 407 and sponge 408 can then be placed inside the liquid storage chamber 402 for storage. As the movable cylinder 407 enters the liquid storage chamber 402, it will press down on the annular screen 406 and compress the return spring 404, generating elastic potential energy to prevent interference with the storage of the movable cylinder 407. After the movable cylinder 407 is removed from the liquid storage chamber 402, the annular screen 406 moves upward under the elastic potential energy of the return spring 404, resetting to above the level of the rust-preventive oil for easy cleaning of impurities. At this time, the annular filter screen 409 can prevent... To prevent dust and other impurities from flowing down into the reservoir 402 and adhering to the bottom of the sponge 408, which would then return to the outside of the steel structure 2 during the next rust prevention maintenance, thus hindering the complete adhesion of the rust-preventive oil, the sealing plate 603 is closed to seal the inside of the reservoir 402, preventing external factors from contaminating the rust-preventive oil inside. When the rust-preventive oil needs to be replaced after a period of use, the rubber plug 602 can be pulled out to open the drain hole 601 to drain the rust-preventive oil inside the reservoir 402, and then the rubber plug 602 can be put back in to close the drain hole 601. New rust-preventive oil can then be poured into the reservoir 402 to complete the replacement.

[0045] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
