Description

Technical Field

[0001] This invention relates to the technical field of rust removal for steel structures, and in particular to a steel structure surface painting device. Background Technology

[0002] I-beams, also known as steel beams, are long steel bars with an I-shaped cross-section. Whether standard or lightweight, I-beams have relatively high and narrow cross-sections, resulting in significant differences in moments of inertia about their two principal axes. Therefore, they can only be used directly in members subjected to bending within their web plane or as components of lattice-type load-bearing members. They are unsuitable for axially compressed members or members subject to bending perpendicular to the web plane, greatly limiting their application. I-beams are widely used in construction and other metal structures. After installation, prolonged exposure to air can lead to paint peeling and rust formation, requiring repainting. Current technology for repainting I-beams primarily involves manual rust removal of the peeling areas using tools, followed by a spray gun application of paint around the I-beam in a circular spray pattern.

[0003] However, due to the complex structure of I-beams and the fact that the existing rust removal methods are mainly physical grinding, it is difficult to completely remove rust from the corners of I-beams by manual grinding, resulting in uneven rust removal. Furthermore, it is easy to miss rust removal areas by visual inspection, which hinders subsequent painting and reduces rust removal efficiency.

[0004] Therefore, there is an urgent need for a steel structure surface painting device to solve the above-mentioned defects. Summary of the Invention

[0005] I. Technical Solution

[0006] To achieve the above objectives, the present invention provides the following technical solution: a steel structure surface painting device, comprising a housing, wherein a rust removal module, a dust extraction and moving module, and a painting module are uniformly arranged from front to back inside the housing, an auxiliary roller assembly is provided at the front end of the housing, and an overflow cover is provided on the outside of the painting module to prevent the paint sprayed from the painting module from overflowing.

[0007] The rust removal module includes a first rust removal and grinding component, a second rust removal and grinding component, and a side grinding component. The first rust removal and grinding component is symmetrically installed at the upper and lower ends inside the housing, and the second rust removal and grinding component is symmetrically installed at the left and right ends inside the housing. A side grinding component is provided on the upper and lower sides of the second rust removal and grinding component, and the side grinding component is installed inside the housing.

[0008] The first and second rust removal and grinding components are identical in structure and size. The first rust removal and grinding component includes a connecting cylinder, a connecting plate, an extrusion block, an electric slider, a movable frame, a grinding block, a first nozzle, a second nozzle, and a conveying unit. The connecting cylinder connects the connecting plate to the outer shell. Extrusion blocks are evenly installed on the connecting plate. An electric slider is installed on the side of the connecting plate, and a movable frame is provided between the electric sliders. A grinding block slides on the movable frame, and the grinding block and the extrusion block are connected by an extrusion fit. A conveying chamber is provided inside the movable frame. The first nozzle and the grinding block, which are connected to the conveying chamber, are arranged intermittently and alternately. The first nozzle targets the flat surface of the I-beam. The second nozzle, installed on the side of the movable frame, is connected to the conveying chamber and targets the corner of the I-beam. The conveying unit, installed on the connecting plate, is connected to the conveying chamber and contains rust remover. The first rust removal and grinding component performs a combination of chemical and physical rust removal on the surface of the H-beam. Specifically, the dust extraction and movement module moves the component over a wide area while the electric slider moves the movable frame back and forth on the connecting plate over a small range. During this back-and-forth movement, the pressing block and grinding block engage, causing the grinding block to extend and retract. When retracting and resetting, the sidewall of the grinding block does not block the nozzle, allowing the rust remover from the conveying unit to spray from nozzle one (no nozzle two does not spray), thus reaching the surface of the H-beam. When extending, the sidewall of the grinding block blocks nozzle one, allowing the rust remover from the conveying unit to spray from nozzle two, thus reaching the corner of the H-beam. Simultaneously, the extended grinding block performs physical rust removal on the chemically rust-removed surface of the H-beam. The combination of the first and second rust removal and grinding components provides localized, reciprocating, dual grinding of the H-beam surface.

[0009] As described above, the outer shell includes shell one and shell two. The left end of shell one is temporarily locked to shell two. Temporary disassembly and assembly between shell one and shell two facilitates the fitting of the outer shell onto the I-beam or its removal.

[0010] As described above, the vacuuming mobile module includes crawling tracks, a first limiting wheel, a second limiting wheel, and a vacuuming module. Crawling tracks are symmetrically installed at the upper and lower ends of the housing. A first limiting wheel is installed in the middle of the left end of the housing. A second limiting wheel is installed in the middle of the housing. The vacuuming module is installed on the housing. The vacuuming port of the vacuuming module is located inside the housing.

[0011] As described above, the paint spraying module includes a paint storage frame and a paint spray head. The paint storage frame with a built-in infusion pump is installed on the upper outer side of the housing, and the paint storage frame is connected to the paint spray head installed on the inner wall of the rear end of the housing.

[0012] The aforementioned grinding block includes a movable block, a return spring, and a grinding layer. The movable block is slidably disposed inside the movable frame, and a return spring is connected between the cavity opened in the movable block and the fixed block disposed in the middle of the movable frame. The return spring plays the role of elastic reset. A grinding layer is installed on the end of the movable block away from the extrusion block. The grinding layer is used to physically remove rust from the surface of the I-beam.

[0013] As mentioned above, the side end of the first nozzle is provided with an inclined spray hole. The inclined spray hole facilitates the spraying of rust remover. The specific usage of the first nozzle is as follows: when the side wall of the movable block in the retracted state does not block the spray hole on one side of the nozzle, the rust remover can be sprayed out from the spray hole. When the movable block extends, the side wall of the movable block blocks the spray hole on one side of the nozzle, and the rust remover is sprayed out from the second nozzle.

[0014] The above-mentioned nozzle two includes a nozzle, a sleeve, a plugging post, a connecting rod and a connecting spring. The nozzle is connected to the delivery chamber. The sleeve is slidably fitted on the outside of the nozzle. A connecting spring is connected between the sleeve and the nozzle. The connecting spring plays the role of elastic reset. A plugging post is set on the connecting rod installed inside the nozzle. The plugging post is used to temporarily block the spray hole opened by the sleeve.

[0015] The aforementioned conveying unit includes a storage frame, a conveying pump, and a telescopic pipe. The storage frame is mounted on a connecting plate, and the conveying pump is connected to the storage frame. A telescopic pipe is connected between the conveying pump and the conveying chamber. The conveying pump extracts the rust remover from the storage frame and outputs it into the conveying chamber through the telescopic pipe.

[0016] The aforementioned side-end grinding assembly includes a working cylinder, a grinding mold, and an electric slider II. The U-shaped grinding mold is mounted on the extended end of the working cylinder, the working cylinder is mounted on a sliding base, the base is mounted on the electric slider II, and the electric slider II is mounted on the inner wall of the outer casing.

[0017] II. Beneficial Effects

[0018] 1. The steel structure surface painting device of the present invention uses a combination of chemical and physical rust removal methods to automatically remove rust from the surface of I-beams. It uses a multi-position spray head structure (spray head one, spray head two) to chemically spray the flat surface and corners of the steel structure, combined with physical rust removal, thereby increasing the area and efficiency of rust removal. During the rust removal process, the device is moved on the I-beams by a mechanized clamping motion, which improves the stability of rust removal, debris removal and painting. Compared with manual circular painting, it reduces the problem of uneven paint spraying.

[0019] 2. The steel structure surface painting device of the present invention uses the combined cooperation of the first rust removal and grinding component, the second rust removal and grinding component, and the side end grinding component to make contact with the corresponding position of the I-beam. Then, the I-beam is treated with rust removal by small-area chemical rust removal and reciprocating grinding. Compared with manual rust removal, the circumferential rust removal of the present invention is more conducive to rust removal and improves the area and comprehensiveness of rust removal.

[0020] 3. The steel structure surface painting device of the present invention, the first rust removal and grinding component mainly performs double rust removal on the surface of the H-beam. The specific rust removal method is as follows: the electric slider one drives the movable frame to move back and forth in a small range on the connecting plate. At the same time as the reciprocating movement, the grinding block is stretched and retracted by the squeezing cooperation between the squeezing block and the grinding block. When the grinding block retracts and returns to its original position, the rust remover is sprayed out from the first nozzle. When the grinding block extends, the rust remover is sprayed out from the second nozzle. The intermittent spraying of the first and second nozzles sprays the rust remover onto different positions of the H-beam, thereby chemically removing rust from different positions of the H-beam. After the rust remover is sprayed out, the grinding block and grinding mold are used to further physically grind and remove rust from the chemically removed positions, thereby improving the rust removal efficiency.

[0030] Embodiments of the present invention will now be described with reference to the accompanying drawings. In this process, to ensure clarity and convenience, we may exaggerate the width of lines or the size of constituent elements in the drawings.

[0031] Furthermore, the terms used below are defined based on the functionality of this invention and may vary depending on the user's, operator's, or conventions. Therefore, these terms are defined based on the entire contents of this specification.

[0032] like Figures 1 to 8 As shown in the figure, the steel structure surface painting device provided by the embodiment of the present invention includes a housing 1. The housing 1 is evenly arranged from front to back with a rust removal module 2, a dust suction moving module 3, and a painting module 4. An auxiliary roller group 5 is provided at the front end of the housing 1. The painting module 4 is covered with an overflow cover 6, which prevents the paint sprayed from the painting module 4 from overflowing.

[0033] The rust removal module 2 includes a first rust removal and polishing component 21, a second rust removal and polishing component 22, and a side polishing component 23. The first rust removal and polishing component 21 is symmetrically installed at the upper and lower ends inside the outer shell 1, and the second rust removal and polishing component 22 is symmetrically installed at the left and right ends inside the outer shell 1. A side polishing component 23 is respectively provided on the upper and lower sides of the second rust removal and polishing component 22, and the side polishing component 23 is installed inside the outer shell 1.

[0034] The first rust removal and grinding assembly 21 and the second rust removal and grinding assembly 22 are identical in structure and size. The first rust removal and grinding assembly 21 includes a connecting cylinder 211, a connecting plate 212, a pressing block 213, an electric slider 214, a movable frame 215, a grinding block 216, a nozzle 217, a nozzle 218, and a conveying unit 219. The connecting cylinder 211 connects the connecting plate 212 to the outer shell 1. The pressing blocks 213 are evenly installed on the connecting plate 212. The electric slider 214 is installed on the side end of the connecting plate 212. A movable frame 215 is provided, on which a grinding block 216 is slidably mounted. The grinding block 216 and the pressing block 213 are connected by a pressing fit. A conveying cavity is provided inside the movable frame 215. A nozzle 217 and the grinding block 216 are intermittently and alternately arranged and installed in communication with the conveying cavity. The nozzle 217 targets the flat surface of the I-beam. A nozzle 218 installed on the side of the movable frame 215 is connected to the conveying cavity and targets the corner of the I-beam. A conveying unit 219 mounted on the connecting plate 212 and... The conveying chambers are interconnected. The conveying unit 219 contains a rust remover. The first rust removal and grinding component 21 performs alternating chemical and physical rust removal on the surface of the passing I-beam. Specifically, the dust extraction and moving module 3 drives the application to move over a large range, while the electric slider 214 drives the movable frame 215 to move back and forth on the connecting plate 212 over a small range. During the reciprocating movement, the pressing block 213 and the grinding block 216 are pressed together, causing the grinding block 216 to move in a telescopic motion. When it retracts and returns to its original position, the side wall of the grinding block 216 is not blocked. The rust remover output from the conveying unit 219 is sprayed from nozzle 217 (nothing is sprayed from nozzle 218), thus spraying onto the surface of the I-beam. When extended, the side wall of the grinding block 216 blocks nozzle 217, causing the rust remover output from the conveying unit 219 to be sprayed from nozzle 218, thus spraying onto the corner of the I-beam. At the same time, the extended grinding block 216 performs physical rust removal on the chemically rust-removed surface of the I-beam. The arrangement of the first rust removal and grinding component 21 and the second rust removal and grinding component 22 performs localized reciprocating double grinding on the surface of the I-beam.

[0035] Specifically, the unlocked and disassembled outer shell 1 is fitted onto the I-beam structure and then merged. The dust-collecting moving module 3 holds the I-beam structure tightly. Then, the first rust removal and grinding component 21, the second rust removal and grinding component 22, and the side grinding component 23 merge towards each other to contact the surface of the I-beam structure. The rust removal module 2 performs chemical and physical rust removal on the surface of the I-beam structure. Then, the dust-collecting moving module 3 moves the application on the I-beam to perform large-area rust removal. After rust removal, the dust-collecting moving module 3 and the painting module 4 powerfully remove the rust debris and apply paint. The application moves on the I-beam in a wrapped manner and then undergoes multiple rust removal processes to achieve a large area and high rust removal rate.

[0036] In another embodiment of the present invention, the outer shell 1 further includes a first shell 11 and a second shell 12. The left end of the first shell 11 is temporarily snapped and locked to the second shell 12. The temporary disassembly and assembly between the first shell 11 and the second shell 12 facilitates the fitting of the outer shell 1 onto the I-beam or its removal.

[0037] Furthermore, the vacuuming moving module 3 includes a crawling track 31, a first limiting wheel 32, a second limiting wheel 33, and a vacuuming module 34. The crawling track 31 is symmetrically installed at the upper and lower ends of the housing 11. The first limiting wheel 32 is installed in the middle of the left end of the housing 11. The second limiting wheel 33 is installed in the middle of the housing 12. The vacuuming module 34 is installed on the housing 11, and the vacuuming port of the vacuuming module 34 is located inside the outer shell 1.

[0038] Specifically, the crawler track 31 drives the application to move on the I-beam, and the first limit wheel 32 and the second limit wheel 33 perform copying and supporting movement. The crawler track 31, the first limit wheel 32 and the second limit wheel 33 hold each other tightly on the I-beam. After rust removal, the dust removal module 34 removes the generated debris.

[0039] Furthermore, the paint spraying module 4 includes a paint storage frame 41 and a paint spray head 42. The paint storage frame 41 with a built-in infusion pump is installed on the upper outer side of the outer casing 1, and the paint storage frame 41 is connected to the paint spray head 42 installed on the inner wall of the rear end of the outer casing 1.

[0040] Specifically, the paint in the paint storage frame 41 is output by the infusion pump and sprayed out from the paint spray head 42, thereby spraying paint on the surface of the rust-removed I-beam.

[0041] Furthermore, the grinding block 216 includes a movable block 2161, a return spring 2162, and a grinding layer 2163. The movable block 2161 is slidably disposed inside the movable frame 215, and the cavity opened in the movable block 2161 is connected to the fixed block in the middle of the movable frame 215 by a return spring 2162, which plays the role of elastic reset. The end of the movable block 2161 away from the pressing block 213 is equipped with a grinding layer 2163, which is used to physically remove rust from the surface of the I-beam.

[0042] Specifically, the electric slider 214 drives the movable frame 215 to reciprocate within a small range on the connecting plate 212. While reciprocating, the movable block 2161 and the polishing layer 2163 move in a telescopic motion due to the pressing engagement between the pressing block 213 and the lower end of the movable block 2161 and the elastic reset of the return spring 2162.

[0043] Furthermore, the side end of the first nozzle 217 is provided with an inclined spray hole. The inclined spray hole facilitates the spraying of rust remover. The specific usage of the first nozzle 217 is as follows: when the side wall of the retracted movable block 2161 does not block the spray hole at the side end of the first nozzle 217, the rust remover can be sprayed out from the spray hole. When the movable block 2161 is extended, the side wall of the movable block 2161 blocks the spray hole at the side end of the first nozzle 217, and the rust remover is sprayed out from the second nozzle 218.

[0044] Furthermore, the second nozzle 218 includes a nozzle 2181, a sleeve 2182, a blocking post 2183, a connecting rod 2184, and a connecting spring 2185. The nozzle 2181 is connected to the delivery chamber. The sleeve 2182 is slidably sleeved on the outside of the nozzle 2181. A connecting spring 2185 is connected between the sleeve 2182 and the nozzle 2181. The connecting spring 2185 plays the role of elastic reset. A blocking post 2183 is provided on the connecting rod 2184 installed inside the nozzle 2181. The blocking post 2183 is used to temporarily block the spray hole opened by the sleeve 2182.

[0045] Specifically, when nozzle 217 is blocked and sealed, the rust remover is sprayed from nozzle 218. The specific spraying method is as follows: the liquid rust remover output by the conveying unit 219 is conveyed to the spray pipe 2181 when the nozzle is blocked. Under the pressure of the liquid rust remover, the sleeve 2182 extends, so that the blocking column 2183 no longer blocks the sleeve 2182, thereby forming an open state, and the rust remover is sprayed out smoothly.

[0046] Furthermore, the conveying unit 219 includes a storage frame 2191, a conveying pump 2192, and a telescopic pipe 2193. The storage frame 2191 is mounted on the connecting plate 212, and the conveying pump 2192 is connected and installed on the storage frame 2191. The telescopic pipe 2193 is connected and installed between the conveying pump 2192 and the conveying chamber.

[0047] Specifically, the rust remover in the storage box 2191 is extracted by the delivery pump 2192 and output from the telescopic tube 2193 into the delivery chamber.

[0048] Furthermore, the side-end grinding assembly 23 includes a working cylinder 231, a grinding mold 232, and an electric slider 233. The U-shaped grinding mold 232 is mounted on the extended end of the working cylinder 231, the working cylinder 231 is mounted on a sliding base, the base is set on the electric slider 233, and the electric slider 233 is mounted on the inner wall of the outer casing 1.

[0049] Specifically, the working cylinder 231 drives the grinding mold 232 to move and fit onto the I-beam. Then, driven by the electric slider 233, the grinding mold 232 grinds the I-beam. The grinding mold 232 mainly targets the corners of the I-beam.

[0050] Work process:

[0051] S1. The outer shell 1, which is in the unlocked and disassembled state, is integrated into the I-beam structure;

[0052] S2. The crawler track 31 drives the application to move on the I-beam, and the rust removal module 2 performs chemical and physical rust removal on the surface of the I-beam structure.

[0053] S3. The application is continuously moved by the crawler track 31, and the dust removal module 34 powerfully removes the rust-removed debris. Then, the paint spraying module 4 sprays paint on the surface of the rust-removed I-beam.

[0054] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
