[0014] Beneficial effects
[0015] This utility model provides a rust removal mechanism for steel plates used in ship repair and construction. Compared with the prior art, it has the following advantages:
[0016] Firstly, the second electric push rod of this utility model is used to push the connecting plates on both sides of the slide rail bracket, so that the slide rail bracket can rotate on the support shaft through the connecting block. This allows the grinding wheel to remove rust and grind the steel plate on the horizontal surface. When the slide rail bracket rotates, the angle of the grinding wheel at the lower end of the slide rail bracket can also be adjusted to fix the grinding wheel in a vertical state. In the process of shipbuilding and repair, the working surfaces of steel plates are diverse, including a large number of horizontally placed steel plates and vertical surfaces such as ship sidewalls. Through the rapid action of the second electric push rod, the grinding wheel can quickly switch between two modes: horizontal grinding for rust removal of flat steel plates and vertical grinding for rust removal of ship sidewalls. There is no need for manual disassembly and reinstallation of the grinding equipment, which greatly saves the operation conversion time, improves the overall rust removal efficiency, can adapt to the rust removal needs of steel plates in different positions and angles, improves work efficiency, and realizes multiple uses of one machine.
[0017] Secondly, the slider body of this utility model is raised and lowered on the slide rail bracket via a first electric push rod, which is used to bring the grinding wheel close to the steel plate for rust removal. It can precisely control the distance and force of the grinding wheel close to the steel plate, and can flexibly adjust the contact pressure between the grinding wheel and the steel plate according to the degree of rust on the steel plate surface. The pressure is increased for severely rusted areas and reduced for thinner or slightly rusted areas to avoid over-grinding or incomplete rust removal, thereby further improving the rust removal quality. In addition, the mounting block on the grinding wheel provides a certain degree of shock absorption and buffering inside the mounting shell through shock-absorbing springs and damping rods, so as to buffer the impact force generated by grinding when the grinding wheel contacts the steel plate for rust removal. This reduces the impact force on the grinding wheel, mounting block, micro motor and other parts of the entire rust removal mechanism, reduces the degree of equipment wear, and extends the service life of each part of the equipment.
[0018] Thirdly, this utility model uses a conduit and an open-structured dust collection shell to quickly clean rust, creating a powerful suction that rapidly lifts rust and other impurities from the steel plate surface and transports them through the conduit to the collection shell. The open-structured dust collection shell increases the suction area, allowing for a wider cleaning range and enabling the cleaning of large areas of impurities in a short time. This improves the overall efficiency of rust removal operations, reduces the impact of residual impurities on subsequent processes, prevents dust from flying in the work area, improves the working environment for operators, and reduces the harm of dust to the human respiratory system. Furthermore, the open-structured dust collection shell has a fixed mesh frame on its inner wall. During the dust collection process, larger impurities such as lumps of rust and grinding debris are intercepted by the mesh frame before being sucked into the equipment, effectively preventing large particles from entering the air pump, conduit, and collection shell. This avoids these impurities causing wear, blockage, or other damage to the internal equipment and extends the service life of the equipment. Attached Figure Description

[0024] 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.
[0025] Please see Figure 1-4 This utility model provides a technical solution: a rust removal mechanism for steel plates used in ship repair and construction, including a movable support 1, on which a rust removal mechanism for steel plates used in ship repair and construction is provided, the rust removal mechanism including:
[0026] The adjustment assembly includes a pair of fixed plates 2 fixed at the upper end of the movable bracket 1, a support shaft 201 rotatably connected through the inside of the fixed plate 2, a connecting block 202 fixed on the outer wall of the support shaft 201, and a slide rail bracket 203 connected by a push assembly fixed at the front end of the connecting block 202.
[0027] The shock absorption assembly includes a slider body 204 connected to the slide rail bracket 203 via a lifting assembly. The lower end of the slider body 204 is fixed with a mounting housing 3, and the lower end of the mounting housing 3 is provided with a grinding wheel 304 connected via an elastic assembly.
[0028] In a preferred embodiment, the pushing assembly includes a collecting shell 5 fixed to the upper surface of the movable bracket 1. A second electric push rod 501, rotatably connected via a rotating shaft, is disposed on the upper surface of the collecting shell 5. A slide rail bracket 203 is fixedly connected to the front wall of the connecting block 202. Connecting plates 502 are fixed to both sides of the slide rail bracket 203. One end of each connecting plate 502 is rotatably connected to the telescopic end of the second electric push rod 501 via a rotating shaft. The second electric push rod 501 is used to push the connecting plates 502 on both sides of the slide rail bracket 203, enabling the slide rail bracket 203 to rotate on the support shaft 201 via the connecting block 202, thus allowing the grinding wheel 304 to remove impurities from the steel plate on the horizontal surface. Rust removal is performed by grinding the grinding wheel 304 at the lower end of the slide rail bracket 203. When the slide rail bracket 203 rotates, the angle of the grinding wheel 304 can be adjusted to fix it in a vertical position. In the shipbuilding and repair process, the steel plate working surfaces are diverse, including a large number of horizontally placed steel plates and vertical surfaces such as ship sidewalls. Through the rapid action of the second electric push rod 501, the grinding wheel 304 can quickly switch between two modes: horizontal grinding for rust removal of flat steel plates and vertical grinding for rust removal of ship sidewalls. There is no need for manual disassembly and reinstallation of the grinding equipment, which greatly saves the operation conversion time, improves the overall rust removal efficiency, and can adapt to the rust removal needs of steel plates in different positions and angles, improve work efficiency, and achieve multi-purpose use of one machine.
[0029] In a preferred embodiment, a conduit 6 is fixed to the front end of the collecting shell 5, and a dust-collecting shell 601 is fixed to one end of the conduit 6. The dust-collecting shell 601 has an open structure, and a mesh frame 602 is fixed to the inner wall of the opening of the dust-collecting shell 601. An air pump 603 is provided on the rear side wall of the collecting shell 5. After grinding, the rust and other impurities fall onto the surface of the steel plate. When the air pump 603 is started, the collecting shell 5 generates negative pressure, and then the rust is quickly cleaned through the conduit 6 and the open dust-collecting shell 601, forming a strong suction force that can quickly suck up the rust and other impurities on the surface of the steel plate and transport them to the collecting shell 5 through the conduit 6. The open dust-collecting shell 601 design increases the dust collection area. This design allows for a wider cleaning range, enabling the removal of large areas of impurities in a short time. It improves the overall efficiency of rust removal operations, reduces the impact of residual impurities on subsequent processes, prevents dust from flying in the work area, improves the working environment for operators, and reduces the harm of dust to the human respiratory system. Furthermore, the dust collection housing 601, with its open structure, has a mesh frame 602 fixed to its inner wall. During the dust collection process, larger impurities, such as lumps of rust and grinding debris, are intercepted by the mesh frame 602 before being sucked into the equipment. This effectively prevents large particles of impurities from entering the air pump 603, the duct 6, and the collection housing 5, thus avoiding wear, blockage, and other damage to the internal equipment and extending the service life of the equipment.
[0030] In a preferred embodiment, the lifting assembly includes a support plate 4 fixed to one side wall of the slide rail bracket 203. A first electric push rod 401 is fixed to the upper end face of the support plate 4. The slider body 204 is fixedly connected to the telescopic end of the first electric push rod 401. The elastic assembly includes a mounting shell 3 fixed to the lower end face of the slider body 204. Shock-absorbing springs 301 are evenly distributed on the lower end face of the mounting shell 3. A damping support rod 302 is provided in the inner ring of the shock-absorbing spring 301. The upper end of the damping support rod 302 is fixedly connected to the mounting shell 3. A mounting block 303 is fixed to the lower end of the shock-absorbing spring 301. The mounting block 303 is internally configured with a micro motor for driving, and the grinding wheel 304 is located at the output end of the micro motor. During grinding, the micro motor inside the mounting block 303 drives the grinding wheel 304 to rotate, ensuring the efficiency and effect of rust removal, and quickly removing rust and impurities from the surface of the steel plate. Then the slider body 204... 4. The first electric push rod 401 is raised and lowered on the slide rail bracket 203 to bring the grinding wheel 304 close to the steel plate for rust removal. The distance and force of the grinding wheel 304 close to the steel plate can be precisely controlled. The contact pressure between the grinding wheel 304 and the steel plate can be flexibly adjusted according to the degree of rust on the steel plate surface. The pressure is increased for severely rusted areas and reduced for thinner or slightly rusted areas to avoid over-grinding or incomplete rust removal, thereby further improving the rust removal quality. In addition, the mounting block 303 on the grinding wheel 304 provides a certain degree of shock absorption and buffering inside the mounting housing 3 through the shock-absorbing spring 301 and the damping support rod 302. This buffers the impact force generated by grinding when the grinding wheel 304 contacts the steel plate for rust removal, effectively absorbing and buffering the impact force, reducing the damage of the impact force to the grinding wheel 304, mounting block 303, micro motor and other components of the entire rust removal mechanism, reducing the degree of equipment wear, and extending the service life of the equipment components.
[0031] In a preferred embodiment, the lower end face of the movable support 1 is provided with a universal wheel 7 for driving, and one end of the movable support 1 is fixed with a push rod bracket 701 for pushing. The push rod bracket 701 facilitates pushing, enabling the equipment to move flexibly at the ship repair site. Operators can easily push the equipment to complete the rust removal task outdoors, thus expanding the application range of the rust removal mechanism.
[0032] The aforementioned micro motor model is N30-050, and the air pump model is RB-61D.
[0033] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
[0034] During operation, the micro motor inside the mounting block 303 drives the grinding wheel 304 to rotate, ensuring the efficiency and effectiveness of rust removal. It can quickly remove rust and impurities from the surface of the steel plate. Then, the slider body 204 is raised and lowered on the slide rail bracket 203 via the first electric push rod 401 to bring the grinding wheel 304 close to the steel plate for rust removal. After grinding, the rust and impurities fall onto the surface of the steel plate. When the vacuum pump 603 is started, the collection shell 5 generates negative pressure. Then, through the conduit 6 and the open-structure dust collection shell 601, the rust is quickly cleaned, forming a strong suction that can quickly suck up the rust and other impurities from the surface of the steel plate and transport them to the collection shell 5 through the conduit 6. The open-structure dust collection shell 601 design increases the dust collection area, making the cleaning range wider and enabling large-area impurity cleaning to be completed in a short time.
[0035] Furthermore, the second electric push rod 501 is used to push the connecting plates 502 on both sides of the slide rail bracket 203, so that the slide rail bracket 203 can rotate on the support shaft 201 through the connecting block 202. This allows the grinding wheel 304 to remove rust and grind the steel plate on the horizontal surface. When the slide rail bracket 203 rotates, the angle of the grinding wheel 304 at the lower end of the slide rail bracket 203 can also be adjusted to fix the grinding wheel 304 in a vertical state. In the process of shipbuilding and repair, the working surfaces of steel plates are diverse, including a large number of horizontally placed steel plates and vertical surfaces such as ship sidewalls. Through the rapid action of the second electric push rod 501, the grinding wheel 304 can quickly switch between two modes: horizontal grinding for rust removal of flat steel plates and vertical grinding for rust removal of ship sidewalls, without the need for manual disassembly and reinstallation of the grinding equipment.
