Description

Technical Field

[0001] This invention relates to the field of steel rust removal technology, and more specifically to a rust removal device for steel structure surfaces. Background Technology

[0002] The main purpose of rust removal on steel structure surfaces is to ensure that the coating can fully exert its effect and avoid large-scale rust spots that would affect the service life of the steel structure surface. This allows for the removal of rust and oxidation areas on the surface using specialized rust removal equipment, ensuring good adhesion of the coating after spraying and improving the smoothness and cleanliness of the steel surface. This, in turn, improves the absorption of the coating and reduces problems such as coating peeling and blistering. In summary, the inventors have found that existing rust removal devices have the following main defects: because current rust removal devices remove rust from steel surfaces by irregularly rotating a rust removal disc, the irregular rotational motion results in low efficiency during rust removal. At the same time, it is impossible to guarantee precise treatment of the steel surface edges, leading to edge omissions. Therefore, the completeness of rust removal on the steel surface by the rust removal device is reduced. Summary of the Invention

[0003] The technical solution adopted by the present invention to achieve the technical objective is: a steel structure surface rust removal device, the structure of which includes: a positioning plate, a drive rail, a connecting column, a connecting block, a rust removal structure, and a placement structure. The upper left and right sides of the positioning plate are connected to the drive rail and the connecting column is installed therein. The connecting block is provided on the upper side of the connecting column to position the center of the rust removal structure. The placement structure is installed at the upper center of the positioning plate and communicates with the lower part of the rust removal structure.

[0004] As a further improvement of the present invention, the rust removal structure is provided with a locking block, which is welded to the left and right sides of the solid block and the center of the solid block positions the vertical control sleeve. The top of the vertical control sleeve is connected to a limit frame to limit the edge of the slide rod. The bottom of the slide rod is connected to a cover plate and a vibration block is provided on the upper layer to drive the scraper of the bottom layer to perform operations.

[0005] As a further improvement of the present invention, auxiliary plates are also provided on the left and right sides of the cover plate. The outer side of the auxiliary plate and the sliding layer are integrated. A positioning frame is connected to the inner side of the auxiliary plate to position one end of the vibration block and an insert block is connected to the lower side. A pointed block is also connected to one end of the insert block and welded to the insert block. A fixing block is connected to the upper layer of the insert block.

[0006] As a further improvement of the present invention, the rust removal structure is vertically installed by the connecting block, and then the vertical control sleeve of the rust removal structure drives the slide rod to slide down, so that the cover plate covers the upper steel surface of the placement structure. Subsequently, the drive rail drives the connecting column to move and the vibration block is powered on to allow the scraper to move horizontally at the rust position on the steel surface. At the same time, the auxiliary plates on the left and right sides of the cover plate make parallel contact with the upper sides of the placement structure through the sliding layer.

[0007] As a further improvement of the present invention, the two drive rails on the upper left and right sides of the positioning plate include a transverse drive motor to control the bottom of the connecting column. The connecting column is set on the left and right sides of the connecting block and the rust removal structure in the center of the connecting block intersects each other. The placement structure is set in a parallel orientation below the rust removal structure and is parallel to the positioning plate.

[0008] As a further improvement of the present invention, the locking block is provided on the left and right sides of the solid block and set in a symmetrical orientation. The vertical control sleeve of the solid block includes a rotating wheel to control the sliding of the limit frame up and down. The vibration block on the cover plate covers the upper layer of the cover plate and drives the scraper to vibrate.

[0009] As a further improvement of the present invention, the auxiliary plate is solid and the shape of the positioning frame it carries matches the shape of the vibration block. The insert block and the auxiliary plate form an "L" shape and the upper layer carries three rubber fixing blocks. The pointed block is triangular solid and is set at the front end of the insert block.

[0010] As a further improvement of the present invention, the scraper is also provided with a rust removal end, and a protrusion is mounted on the upper side of the rust removal end to weld the lower end of the splice body. The surface of the splice body carries a locking groove and is embedded in the side position of the cover plate and locked by bolts.

[0011] As a further improvement of the present invention, the rust removal end is sharp and solid in shape and is triangular trapezoidal. The protrusion of the rust removal end is perpendicular to the splicing body, and the side of the splicing body is provided with three locking grooves to allow ordinary bolts to pass through and complete the splicing with the side of the cover plate.

[0012] As a further improvement of the present invention, the placement structure is provided with a support block, which is welded to the lower corner of the base plate and a straight plate is connected to the upper edge of the base plate to limit the left and right sides of the fixture to the upper center of the base plate. A slider is also provided at the lower end of the base plate and the lower end of the slider is connected to the upper left and right sides of the collection box. The collection box has a collection groove inside and a pull block is connected to the center of the outside.

[0013] As a further improvement of the present invention, the support block is provided with four blocks at the lower corner of the base plate and is set in a vertical direction. The two straight plates on the base plate and the sliding layer of the auxiliary plate are in parallel contact with each other, and the central fixing device is set in a parallel direction. Two straight slides are also opened at the contact position between the lower end of the base plate and the slider.

[0014] As a further improvement of the present invention, the fixture is also provided with a slot, which is located inside the extension block and the extension block is distributed on the left and right sides of the magnetic block. The contact layer on the magnetic block contacts the lower steel layer and one end is also equipped with a blocking element.

[0015] As a further improvement of the present invention, the shape of the slot is consistent with the shape of the extension block and the lower end of the straight plate is fixed, the contact layer of the magnetic block is parallel and the top of the blocking member at one end is contacted by the bottom layer of the cover plate.

[0016] As a further improvement of the present invention, the blocking member is also provided with a force-receiving end, which is located at the upper end of the blocking block. The lower end of the blocking block is connected to a spring shaft, which is embedded in the through groove and in contact with the interior of the vertical block. The exterior of the vertical block is also equipped with a splicing rod embedded in the inner side of the magnetic block.

[0017] As a further improvement of the present invention, the blocking block is solid and overlaps with the center of the elastic shaft at the lower end. The elastic shaft has a built-in vertical spring, and the through slot of the vertical block is opened in a vertical orientation.

[0018] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention further improves the rust removal structure by using a solid block locking block to stably install the vertical control sleeve at the center of the connecting block. Then, the rotating wheel inside the vertical control sleeve controls the position of the sliding rod by rotating forward and backward, allowing the cover plate to carry the vibrating block and scraper to descend parallel to the edge of the placement structure and align with the edge of the steel surface. Subsequently, the connecting column moves horizontally in the drive track area to directly scrape off the rust on the steel surface. During the process, the vibration block drives the scraper to shake, which improves the rust removal intensity on the steel surface. Therefore, it can improve the efficiency and accuracy of rust removal and avoid the situation where the edge area is difficult to treat properly.

[0019] 2. This invention further improves the placement structure by using four support blocks to enhance the balance and stability of the connection between the base plate and the positioning plate. Then, the left and right straight plates on the fixing device vertically limit the auxiliary plates on the left and right sides of the cover plate, allowing the auxiliary plates to slide linearly on the straight plate surface when the connecting column of the drive track moves horizontally. This improves the balanced rust removal effect. Simultaneously, pulling the bottom collection box exposes the collection trough, allowing scraped rust to fall directly into the collection trough for rust collection. Subsequently, the magnetic block of the fixing device adsorbs and positions the steel surface, allowing one end of the steel structure to be directly pushed into the blocking position during placement, achieving the required positioning limit. Then, when the cover plate carrying the scraper falls, the top of the blocking block of the blocking device is stressed, pressing down the spring shaft to ensure the scraper is stably aligned with the steel edge. As the scraper moves parallel and moves away from the stressed end, the blocking block rebounds and limits the position again, achieving a stable alignment effect. Attached Figure Description

Detailed Implementation

[0028] The present invention will be further described below with reference to the accompanying drawings: Example 1: Figures 1 to 4 As shown: This invention provides a rust removal device for steel structure surfaces. Its structure includes a positioning plate 1, a drive rail 2, a connecting column 3, a connecting block 4, a rust removal structure 5, and a placement structure 6. The upper left and right sides of the positioning plate 1 are connected to the drive rail 2 and the connecting column 3 is installed therein. The connecting block 4 is provided on the upper side of the connecting column 3 to position the center of the rust removal structure 5. The placement structure 6 is installed at the upper center of the positioning plate 1 and communicates with the lower part of the rust removal structure 5.

[0029] As a further improvement of the present invention, the rust removal structure 5 is provided with a locking block 51, which is welded to the left and right sides of the solid block 52 and the center of the solid block 52 positions the vertical control sleeve 53. The top of the vertical control sleeve 53 is connected to a limit frame 54 to limit the edge of the slide rod 55. The bottom of the slide rod 55 is connected to a cover plate 56 and a vibration block 57 is provided on the upper layer to drive the scraper 58 of the bottom layer to perform operations.

[0030] As a further improvement of the present invention, auxiliary plates 562 are also provided on the left and right sides of the cover plate 56. The outer side of the auxiliary plate 562 is integrated with the sliding layer 561. A positioning frame 563 is connected to the inner side of the auxiliary plate 562 to position one end of the vibration block 57, and an insert block 564 is connected to the lower side. A pointed corner block 565 is also connected to one end of the insert block 564 and welded to the insert block 564. A fixing block 566 is connected to the upper layer of the insert block 564.

[0031] As a further improvement of the present invention, the rust removal structure 5 is vertically installed by the connecting block 4. Then, the vertical control sleeve 53 of the rust removal structure 5 drives the slide rod 55 to slide down, so that the cover plate 56 covers the upper steel surface of the placement structure 6. Subsequently, combined with the drive rail 2 to drive the connecting column 3 to move and the vibration block 57 to be powered on, the scraper 58 moves horizontally at the rust position on the steel surface. At the same time, the auxiliary plates 562 on the left and right sides of the cover plate 56 make parallel contact with the upper sides of the placement structure 6 through the sliding layer 561.

[0032] As a further improvement of the present invention, the two drive rails 2 on the left and right sides of the upper end of the positioning plate 1 include a transverse drive motor to control the bottom end of the connecting column 3. The connecting column 3 is set on the left and right sides of the connecting block 4 and the rust removal structure 5 in the center of the connecting block 4 intersects each other. The placement structure 6 is set in a parallel position below the rust removal structure 5 and is parallel to the positioning plate 1.

[0033] As a further improvement of the present invention, the locking block 51 is provided on the left and right sides of the solid block 52 and is set in a symmetrical position. The vertical control sleeve 53 of the solid block 52 includes a rotating wheel to control the sliding rod 55 of the limiting frame 54 to slide up and down. The vibration block 57 on the cover plate 56 covers the upper layer of the cover plate 56 and drives the scraper 58 to perform vibration operation.

[0034] As a further improvement of the present invention, the auxiliary plate 562 is solid and the shape of the positioning frame 563 it carries matches the shape of the vibration block 57. The insert block 564 forms an "L" shape with the auxiliary plate 562 and carries three rubber fixing blocks 566 on the upper layer. The pointed block 565 is triangular solid and is located at the front end of the insert block 564.

[0035] As a further improvement of the present invention, the scraper 58 is also provided with a rust removal end 581. The upper side of the rust removal end 581 is equipped with a protrusion 582 to weld the lower end of the splice body 583. The surface of the splice body 583 carries a locking groove 584 and is embedded in the side position of the cover plate 56 and locked by bolts.

[0036] As a further improvement of the present invention, the rust removal end 581 is sharp and solid in shape and is a triangular trapezoid. The protrusion 582 of the rust removal end 581 is perpendicular to the splicing body 583, and the side of the splicing body 583 is provided with three locking grooves 584 to allow ordinary bolts to pass through and complete the splicing with the side of the cover plate 56.

[0037] The specific functions and operation procedures of this embodiment are as follows: In this invention, the steel structure surface rust removal device can position the drive rail 2 and the placement structure 6 using the positioning plate 1. Then, the connecting column 3 in the drive rail 2 can install the connecting block 4, so that the rust removal structure 5 can be positioned above the placement structure 6 via the connecting block 4. After the steel to be rusted is placed parallel to the surface of the placement structure 6, the rust removal structure 5 can achieve parallel rust removal on the steel surface by moving the connecting column 3 of the connecting block 4 within the drive rail 2 (the drive rail 2 has a built-in drive motor and sliding block, which can stably drive the connecting column 3 to move stably). This allows it to replace the original turntable's irregular movement to remove rust from the steel surface, and parallel rust removal improves the precision of rust removal. The accuracy is ensured and the situation where the edge position cannot be properly treated is prevented. Then, the solid block 52 of the rust removal structure 5 can be installed on the surface of the connecting block 4 through the left and right locking blocks 51. Then, the vertical control sleeve 53 in the center of the solid block 52 can pass through the center of the connecting block 4, so that the sliding rod 55 in the limit frame 54 carries the cover plate 56 in a vertical position and installs it above the placement structure 6. Then, the vertical control sleeve 53 can control the sliding rod 55 to move forward and reverse through the built-in rotating wheel, so that the scraper 58 of the cover plate 56 can approach and align with the steel surface or move away from the steel surface. Then, when the scraper 58 moves to the edge of the steel surface, the vibration block 57 set on the cover plate 56 can be activated by electric control, so that it can drive the scraper. The blade 58 vibrates, and then the scraper 58 moves parallel to the surface of the structure 6 according to the vibration translation method, so that the rust on the steel surface can be scraped off in parallel. The length of the cover plate 56 can also treat the rust at the edge of the steel surface at the same time, thus improving the rust removal efficiency and accuracy of the steel surface and preventing the occurrence of edge omissions. Then, the auxiliary plates 562 set on the left and right sides of the cover plate 56 can position one end of the vibrating block 57 through the positioning frame 563. Then, the pointed corner block 565 of the insert block 564 is inserted into the side of the cover plate 56 in a straight line, and the rebound effect of the fixing block 566 is used to fix it, so that the auxiliary plate 562 can be stably fixed to the cover plate 56. The fixed splicing effect allows the sliding layer 561 to make parallel contact with the components of the placement structure 6, thus achieving stability during the translation of the scraper 58 and preventing shaking. Finally, the rust-removing end 581 of the scraper 58 can be vertically embedded into one end of the cover plate 56 through the cooperation of the protrusion 582 and the splicing body 583. Then, combined with the three locking slots 584 of the splicing body 583, ordinary bolts can pass through one end of the cover plate 56 to lock it, so that the scraper 58 and the cover plate 56 can be easily disassembled. At the same time, the vertical embedding of the protrusion 582 and the splicing body 583 can improve the parallel fixing effect of the rust-removing end 581, prevent tilting, and indirectly improve the stability during rust removal.

[0038] Example 2: Figures 5 to 7 As shown: This invention provides a rust removal device for steel structure surfaces. Its structure includes a support block 61 on the placement structure 6, which is welded to the lower corner of the base plate 62. A straight plate 63 is connected to the upper edge of the base plate 62 to limit the left and right sides of the fixer 64 to the center of the upper layer of the base plate 62. A slider 65 is also provided at the lower end of the base plate 62, and the lower end of the slider 65 is connected to the upper left and right sides of the collection box 66. The collection box 66 has a collection groove 67 inside and a pull block 68 connected to the center of the outside.

[0039] As a further improvement of the present invention, the support block 61 is provided with four blocks at the lower corner of the base plate 62 and is set in a vertical direction. The two straight plates 63 on the base plate 62 are in parallel contact with the sliding layer 561 of the auxiliary plate 562 and the central fixing device 64 is set in a parallel direction. Two straight slides are also opened at the contact position between the lower end of the base plate 62 and the slider 65.

[0040] As a further improvement of the present invention, the fixing device 64 is also provided with a slot 641, the slot 641 is located inside the extension block 642 and the extension block 642 is distributed on the left and right sides of the magnetic block 643, the contact layer 644 on the magnetic block 643 contacts the lower steel layer and one end is also equipped with a blocking member 645.

[0041] As a further improvement of the present invention, the shape of the slot 641 is consistent with the shape of the extension block 642 and the lower end of the straight plate 63 is fixed. The contact layer 644 of the magnetic block 643 is in a parallel shape and the top of the blocking member 645 at one end is contacted by the bottom layer of the cover plate 56.

[0042] As a further improvement of the present invention, the blocking member 645 is also provided with a force-receiving end 6451, which is located at the upper end of the blocking block 6452. The lower end of the blocking block 6452 is connected to a spring shaft 6453, and the spring shaft 6453 is embedded in the through groove 6454 and in contact with the interior of the vertical block 6455. The vertical block 6455 is also equipped with a splicing rod 6456, which is embedded in the inner side of the magnetic block 643.

[0043] As a further improvement of the present invention, the blocking block 6452 is solid and overlaps with the center of the lower elastic shaft 6453. The elastic shaft 6453 has a built-in vertical spring, and the through slot 6454 of the vertical block 6455 is opened in a vertical orientation.

[0044] The specific functions and operation procedures of this embodiment are as follows: In this invention, the base plate 62 of the placement structure 6 can be stably installed on the positioning plate 1 via four sets of edge support blocks 61, so that the base plate 62 can be parallel to the positioning plate 1. Then, the left and right edge straight plates 63 on the base plate 62 can make parallel contact with the sliding layer 561 of the auxiliary plate 562 to achieve a limiting effect. Therefore, when the auxiliary plate 562 slides on the surface of the straight plate 63 via the sliding layer 561, it can improve the stability of the cover plate 56 carrying the scraper 58. Then, the fixing device 64 at the center of the surface of the base plate 62 can be engaged with the bottom of the straight plate 63 via the left and right side extension blocks 642 and the slot 641. The steel plate is attracted to the contact layer 644 of the magnetic block 643, allowing it to be placed stably. Simultaneously, when the steel plate is pushed in straight, one end is limited by the position of the blocking member 645, achieving a positional assistance effect during installation and preventing positional errors caused by unrestricted placement. Furthermore, the vertical block 6455 of the blocking member 645 can be vertically installed on the side of the magnetic block 644 and the base plate 62 via the splicing rod 6456. The through groove 6454 in the vertical block 6455 allows the spring shaft 6453 to be installed vertically, ensuring the surface of the blocking block 6452 at the upper end of the spring shaft 6453 is protected. When the scraper 58 is positioned at the opening of the rust removal structure 5, it first descends to press down the force block 6451 of the blocking block 6452, causing the spring shaft 6453 to retract into the through groove 6454. After the blocking block 6452 enters the through groove 6453, the scraper 58 can stably align with the edge of the contact layer 644, achieving alignment with the edge of the steel plate. Then, during the flat rust removal, as the scraper 58 gradually moves away from the force end 6451, the spring shaft 6453 rebounds, allowing the blocking block to retract into the through groove 6454. 6452 is reset so that the accuracy of the scraper 58 before operation is not affected while limiting the position of the steel plate, thus improving the overall strength of the components. During rust removal, the collection box 66 at the bottom of the base plate 62 can be manually pulled outward by the pull block 68. During the process, the slider 65 of the collection box 66 can be moved horizontally, exposing the collection groove 67. With the cooperation of the collection box 66, the rust generated during the horizontal movement can be pushed straight into the collection groove 67 area, achieving the effect of rust collection and further improving the strength of the rust removal device.
