Description

Technical Field

[0001] This invention is a rust removal device for marine engineering equipment, belonging to the marine field. Background Technology

[0002] Besides being used in building structures, I-beams are also commonly used in the exterior and marine engineering structures of large ships due to their light weight and ease of construction. However, the prolonged exposure of steel structures to the marine atmosphere creates conditions conducive to corrosion. The marine atmosphere refers to the atmosphere above the ocean surface. The high humidity of the marine atmosphere increases capillary adsorption on the steel structure surface, and the high chloride content in the air makes it easy for chloride ions to dissolve in the water film on the steel structure surface. This means that even if the steel structure is not in direct contact with seawater, it is very prone to rusting, necessitating the grinding and rust removal of the steel surface.

[0003] In marine engineering environments, limited site conditions make it unsuitable to use large-scale rust removal equipment. Therefore, grinding wheels are generally used for rust removal. However, traditional grinding and rust removal mechanisms cannot grind all surfaces of the U-shaped steel in one go. Furthermore, the distribution of the U-shaped steel on site varies depending on the grinding and rust removal requirements. For example, there may be vertical and horizontal U-shaped steel on site. Existing equipment cannot meet the requirement of switching between grinding horizontal and vertical steel. Moreover, the large amount of rust dust generated during grinding will be re-adsorbed on the surface of the steel structure, increasing the cleaning burden for subsequent painting. Therefore, existing rust removal and grinding equipment suffers from low work efficiency and insufficient applicability. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a rust removal device for marine engineering equipment.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: A rust removal device for marine engineering equipment includes a mobile base, a lifting frame fixedly mounted on the top of the mobile base, a lifting assembly mounted on the lifting frame, a movable square plate fixedly mounted on the lifting assembly, a longitudinal rust removal assembly rotatably mounted on the movable square plate, a movable assembly mounted on the longitudinal rust removal assembly, and a transverse rust removal assembly connected to the movable assembly. Both the longitudinal and transverse rust removal assemblies include an adjustment assembly and a dust extraction assembly. The adjustment assembly includes an adjustment seat with an internal cavity, a drive motor mounted on one side of the adjustment seat, and the output end of the drive motor connected to the adjustment seat. The base contains a dual-axis lead screw, with a grinding seat threaded onto both ends. The grinding seat is also hollow, and an electric telescopic rod is installed inside. The output end of the electric telescopic rod is connected to a heating element, and a wire brush is installed on the heating element. The dust collection component includes a U-shaped mounting base installed on the adjusting base, and a vacuum cleaner is installed on the U-shaped mounting base. A dust collection pipe is connected to the vacuum cleaner. The end face of the grinding seat facing the wire brush has two rows of dust collection ports, with multiple ports in each row, evenly spaced. Each dust collection port has a dust collection head, and the dust collection pipe is connected to the dust collection head.

[0006] Furthermore, the other end of the dual-axis lead screw is connected to a bearing fixed on the outer wall of the adjusting seat. The grinding seat is equipped with a U-shaped dust suction chamber, and the upper and lower rows of dust suction heads are connected to the dust suction chamber.

[0007] Furthermore, two telescopic pipes are connected to the vacuum pipe, with one end of each telescopic pipe inserted into the grinding seat and connected to the vacuum chamber.

[0008] Furthermore, the movable component includes an L-shaped connecting plate fixed on the adjusting seat of the longitudinal rust removal component, and a secondary electric telescopic rod is fixed on the L-shaped connecting plate. The output end of the secondary electric telescopic rod is connected to the adjusting seat on the transverse rust removal component.

[0009] Furthermore, the adjusting seat of the transverse rust removal component is equipped with a support component, which consists of two L-shaped support rods that slide onto the grinding seat of the longitudinal rust removal component.

[0010] Furthermore, the lifting assembly includes a lead screw disposed inside the lifting frame, a threaded seat fitted on the outer surface of the lead screw, the threaded seat slidingly fitting against the inner side of the lifting frame, a second drive motor for driving the lead screw installed at the bottom of the movable base, and a second bearing fitted at the top of the lead screw.

[0011] Furthermore, the heating assembly includes a connecting plate fixed to the output end of the electric telescopic rod. The connecting plate extends to the outside of the grinding seat. A transverse sliding groove is arranged on the outer surface of the grinding seat for the connecting plate to pass through. A heating plate is fixed at the other end of the connecting plate. A heating groove is opened on the heating plate, and an electric heating wire is arranged in the heating groove.

[0012] Furthermore, a mounting groove is provided on the back of the wire brush plate, and the heating plate is inserted into the mounting groove. Mounting holes are provided at both ends of the wire brush plate and the heating plate, and mounting screws are screwed into the mounting holes.

[0013] Furthermore, a bearing three is embedded in the center of the front of the movable square plate, and the back of the movable square plate is mounted on the lifting frame. A drive connecting rod is provided on the inner ring of the bearing three, and the drive connecting rod is connected to the center of the back of the lifting frame. Multiple mounting plates are fixed at the top and bottom of the adjusting seat of the longitudinal rust removal component, and threaded holes are provided on the mounting plates.

[0014] Furthermore, the movable square plate has a secondary threaded hole two corresponding to the threaded hole one, and the movable square plate also has a threaded hole three. Electric pulleys are installed at the four corners of the bottom of the movable base, and locking screws with manual turntables are threaded through the four corners of the bottom of the movable base. Scale lines are engraved on the outer side of the adjusting seat.

[0015] The beneficial effects of this invention are: The steel wire brushes on the grinding seats of the longitudinal rust removal assembly correspond to the vertically arranged U-shaped steel, with the two steel wire brushes on the longitudinal rust removal assembly precisely corresponding to the two sides of the U-shaped steel. When the drive motor is turned on, it drives the rotation of the double-shaft lead screw, which in turn causes the two grinding seats connected to it to move relative to each other, that is, to move the two grinding seats away from each other or closer to each other. Ultimately, it causes the steel wire brushes connected to them to move relative to each other, so that the steel wire brushes slowly come into contact with the two sides of the vertically arranged U-shaped steel. Combined with the reciprocating motion of the electric telescopic rod, the steel wire brushes reciprocate to grind the two sides of the U-shaped steel, thus removing rust from its surface.

[0016] The steel wire brushes on the grinding seats of the horizontal rust removal assembly correspond to the vertically arranged U-shaped steel. The two steel wire brushes on the vertical rust removal assembly correspond to the other two sides of the U-shaped steel. Then, the drive motor on the horizontal rust removal assembly is turned on, which drives the rotation of the double-shaft lead screw. This causes the two grinding seats to move relative to each other, moving away from or towards each other. Ultimately, this causes the steel wire brushes connected to them to move relative to each other, so that the steel wire brushes slowly come into contact with the other two sides of the vertically arranged U-shaped steel. Combined with the reciprocating motion of the electric telescopic rod on the horizontal rust removal assembly, the steel wire brushes reciprocate to grind the other two sides of the U-shaped steel, removing rust from the surface. This achieves rust removal of the entire surface of the U-shaped steel structure in one operation, improving work efficiency.

[0017] The lifting assembly is designed to adjust the height of the longitudinal and transverse rust removal components, thus completing the rust removal work on the high surface. Therefore, the lifting assembly is designed so that the wire brush can work on rust removal areas at different heights, improving the effectiveness of the device.

[0018] By installing a vacuum cleaner, along with a vacuum pipe and a vacuum head, the floating rust dust generated during the grinding and rust removal of the outer surface of the steel body can be sucked up and collected, thereby reducing the dispersion of rust dust and avoiding pollution of the working environment. At the same time, it effectively prevents the floating rust dust from being re-adsorbed onto the steel structure surface, ensuring the quality of subsequent anti-rust paint spraying.

[0019] The longitudinal rust removal component is installed by rotating it on the movable square plate. The longitudinal and transverse rust removal components are indirectly connected as a whole. Therefore, according to the actual needs, the longitudinal rust removal component can be rotated to a vertical position from the state shown in the figure. In this way, the longitudinal and transverse rust removal components in the vertical position can perform rust removal work on transversely arranged U-shaped steel. The entire rust removal equipment is simply designed and can meet the rust removal needs of transversely and vertically arranged U-shaped steel surfaces, further improving the working efficiency of the entire equipment.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see Figure 1-8 This invention provides a rust removal device for marine engineering equipment, comprising a mobile base 1, a lifting frame 2 fixedly mounted on the top of the mobile base 1, a lifting assembly mounted on the lifting frame 2, a movable square plate 3 fixedly mounted on the lifting assembly, a longitudinal rust removal assembly rotatably mounted on the movable square plate 3, a movable assembly mounted on the longitudinal rust removal assembly, and a transverse rust removal assembly connected to the movable assembly. Both the longitudinal and transverse rust removal assemblies include an adjustment assembly and a dust extraction assembly. The adjustment assembly includes an adjustment seat 4 with an internal cavity, a drive motor 5 mounted on one side of the adjustment seat 4, and a dual-axis lead screw connected to the output end of the drive motor 5 located inside the adjustment seat 4. 6. Both ends of the dual-axis lead screw 6 are threaded with grinding seats 7. The grinding seats 7 are also hollow. An electric telescopic rod 8 is installed inside the grinding seats 7. The output end of the electric telescopic rod 8 is connected to a heating component. A wire brush plate 9 is installed on the heating component. The dust collection component includes a U-shaped mounting seat 10 installed on the adjusting seat 4. A vacuum cleaner 11 is installed on the U-shaped mounting seat 10. A dust collection pipe 12 is connected to the vacuum cleaner 11. The end face of the grinding seat 7 facing the wire brush plate 9 is provided with two rows of dust collection ports 13. There are multiple dust collection ports 13 in each row, and they are evenly spaced. A dust collection head 14 is provided in the dust collection port 13. The dust collection pipe 12 is connected to the dust collection head 14.

[0025] See Figure 1-3The other end of the dual-axis lead screw 6 is connected to a bearing 15 fixed on the outer wall of the adjusting seat 4. The grinding seat 7 has a U-shaped dust collection chamber 16 inside. The upper and lower rows of dust collection heads 14 are connected to the dust collection chamber 16. Two telescopic pipes 17 are connected to the dust collection pipe 12. One end of the telescopic pipe 17 is inserted into the grinding seat 7 and connected to the dust collection chamber 16. The design of the bearing 1 ensures the stability of the dual-axis lead screw during rotation. The dust collection chamber 16 is U-shaped with two ends that correspond to the two rows of dust collection heads 14. The two rows of suction heads 14 correspond precisely to the upper and lower ends of the wire brush plate 9, thus enabling vertical suction of the grinding area, expanding the suction range, and effectively ensuring the suction effect. The design of the telescopic pipe 17 connects the suction pipe 12 and the suction chamber 16. The telescopic pipe 17 itself is telescopic, so it can extend and retract when the two opposing grinding seats 7 move relative to each other, thus ensuring that the suction pipe 12 and the suction chamber 16 are always connected.

[0026] See Figure 1 and Figure 3 The moving component includes an L-shaped connecting plate 18 fixed on the adjusting seat 4 of the longitudinal rust removal component. A secondary electric telescopic rod 19 is fixedly mounted on the L-shaped connecting plate 18. The output end of the secondary electric telescopic rod 19 is connected to the adjusting seat 4 of the transverse rust removal component. A support component is mounted on the adjusting seat 4 of the transverse rust removal component. The support component consists of two L-shaped support rods 20, which slidably overlap on the grinding seat 7 of the longitudinal rust removal component. The secondary electric telescopic rod 19 directly drives the transverse rust removal component to move, thus causing the transverse rust removal component to move closer to the other two sides of the U-shaped steel. Normally, the auxiliary electric telescopic rod 19 drives the transverse rust removal component to retract, ensuring that the longitudinal rust removal component can smoothly align with both sides of the U-shaped steel. When the auxiliary electric telescopic rod 19 moves the transverse rust removal component, the designed L-shaped support rod 20 always slides and overlaps on the grinding seat 7 of the longitudinal rust removal component. Therefore, the L-shaped support rod 20 provides contact for the transverse rust removal component during sliding and provides support for the transverse rust removal component when it is not sliding, avoiding the auxiliary electric telescopic rod 19 providing sole support for the transverse rust removal component and ensuring support stability.

[0027] See Figure 1 and Figure 4The lifting assembly includes a lead screw 21 installed inside the lifting frame 2. A threaded seat 22 is fitted on the outer surface of the lead screw 21. The threaded seat 22 slides against the inner side of the lifting frame 2. A second drive motor 23 for driving the lead screw 21 is installed at the bottom of the movable base 1. A second bearing 24 is fitted on the top of the lead screw 21. When the second drive motor 23 is turned on, the lead screw 21 is rotated, which in turn causes the threaded seat 22 to move on the lead screw 21. Ultimately, this causes all the wire brushes 9 to move, enabling the wire brushes 9 to work on rust removal areas at different heights, thus improving the effectiveness of the device.

[0028] See Figure 5-6 The heating assembly includes a connecting plate 25 fixed to the output end of the electric telescopic rod 8. The connecting plate 25 extends to the outside of the grinding base 7. A transverse sliding groove 28 is arranged on the outer surface of the grinding base 7 for the connecting plate 25 to pass through. A heating plate 29 is fixedly provided at the other end of the connecting plate 25. A heating groove 30 is provided on the heating plate 29, and an electric heating wire 31 is arranged in the heating groove 30. An installation groove 32 is provided on the back of the wire brush plate 9, and the heating plate 29 is inserted into the installation groove 32. Installation holes 33 are provided at both ends of the wire brush plate 9 and the heating plate 29, and installation screws are screwed into the installation holes 33. The installation groove 32 is provided on the back of the wire brush plate 9, so the heating plate 29 is directly... Insert the wire brush 9 into the corresponding mounting slot 32. At this time, the mounting holes 33 on the wire brush 9 and the heating plate 29 correspond to each other and are fixed with the mounting screws. Therefore, the wire brush 9 can be detached and installed. If the wire brush 9 is damaged, it can be replaced with a new one. Before operation, the stability of the entire equipment installation must be checked. The wire brush 9 needs to be checked in advance before operation. When the electric heating wire 31 is energized, the heating plate 29 generates heat and transfers it to the wire brush 9. The parts that need to be derusted can be heated. After heating, the steel parts can be derusted. The rust on the surface of the steel bars becomes loose and easy to handle, improving the efficiency of the device in derusting steel bars.

[0029] See Figure 1 , Figure 2 , Figure 7 and Figure 8A bearing 34 is embedded in the center of the front of the movable square plate 3. The back of the movable square plate 3 is mounted on the lifting frame 2. A drive connecting rod 35 is installed on the inner ring of the bearing 34, which connects to the center of the back of the lifting frame 2. Multiple mounting plates 36 are fixed at the top and bottom of the adjusting seat 4 of the longitudinal rust removal component. Threaded holes 37 are opened on the mounting plates 36. A secondary threaded hole 38 corresponding to the threaded hole 37 is opened on the movable square plate 3. Threaded holes 39 are also opened on the movable square plate 3. Electric pulleys 40 are installed at the four corners of the bottom of the movable base 1, and locking screws 27 with manual turntables 26 are threaded through the four corners of the bottom of the movable base 1. Scale lines 41 are engraved on the outer side of the adjusting seat 4, allowing personnel to manually rotate the adjusting seat 4 of the longitudinal rust removal component. The configured bearing 3 ensures the stability and smoothness of rotation, thus allowing the longitudinal and transverse rust removal components to switch from a transverse state to a vertical state. The equipment is used to remove rust from horizontally arranged U-shaped steel, further improving the overall efficiency. After switching to the vertical position, the threaded holes 37 on the mounting plate 36 correspond one-to-one with the threaded holes 39. Screws and other installation tools can be inserted to fix the vertical and horizontal rust removal components. With the electric pulleys 40, the equipment is easy to move and can better remove rust from horizontal steel. When the equipment does not need to be moved, the manual turntable 26 can be rotated to make the locking screw 27 contact the ground, ensuring the stability of the equipment. The scale line 41 shows the distance between the two relative grinding seats 7 after they move relative to each other, which can better correspond to the rust removal work of steel with different thicknesses. It should be noted that the thickness of the steel on both sides should be measured in advance before adjusting the distance between the relative grinding seats 7 to more accurately contact the steel surface for rust removal.

[0030] In use, the wire brushes 9 on the grinding seats 7 of the longitudinal rust removal assembly correspond to the vertically arranged U-shaped steel, and the two wire brushes 9 on the longitudinal rust removal assembly correspond exactly to the two sides of the U-shaped steel. Then, the drive motor 5 is turned on, driving the rotation of the double-shaft lead screw 6, which in turn causes the two grinding seats 7 connected to it to move relative to each other, that is, to move the two grinding seats 7 away from each other or closer together. Ultimately, this causes the wire brushes 9 connected to them to move relative to each other, so that the wire brushes 9 slowly contact the two sides of the vertically arranged U-shaped steel. Combined with the reciprocating motion of the electric telescopic rod 8, the wire brushes 9 perform reciprocating grinding work on the two sides of the U-shaped steel, removing rust from its surface. This is achieved through the transverse rust removal assembly. The wire brushes 9 on the upper grinding seat 7 correspond to the vertically arranged U-shaped steel. The two wire brushes 9 on the longitudinal rust removal assembly correspond to the other two sides of the U-shaped steel. Then, the drive motor 5 on the transverse rust removal assembly is activated, driving the double-shaft lead screw 6 to rotate. This causes the two grinding seats 7 connected to it to move relative to each other, moving them away from or closer together. Ultimately, this causes the wire brushes 9 connected to them to move relative to each other, so that the wire brushes 9 slowly contact the other two sides of the vertically arranged U-shaped steel. Combined with the reciprocating motion of the electric telescopic rod 8 on the transverse rust removal assembly, the wire brushes 9 perform reciprocating grinding work on the other two sides of the U-shaped steel, removing rust from its surface. This system achieves one-time rust removal of the entire surface of the U-shaped steel structure, improving work efficiency. The lifting assembly allows for height adjustment of the longitudinal and transverse rust removal components, facilitating rust removal at higher elevations. The lifting assembly enables the wire brush 9 to work on rust-removing areas at different heights, enhancing the device's effectiveness. A vacuum cleaner 11, along with suction pipes 12 and suction heads 14, collects floating rust dust generated during grinding and rust removal of the steel structure's outer surface, reducing dust dispersion and preventing environmental pollution. It also effectively prevents floating rust dust from re-adhering to the steel structure surface, ensuring smooth subsequent spraying. The quality of the anti-rust paint spraying is important. The vacuum cleaner 11 has a storage space inside to collect rust dust, which is an existing device structure and will not be described in detail here. The longitudinal rust removal component is installed on the movable square plate 3 by rotation. The longitudinal and transverse rust removal components are indirectly connected as a whole. Therefore, according to the actual needs, the longitudinal rust removal component can be rotated to make it rotate from the state shown in the figure to a vertical state. In this way, the longitudinal and transverse rust removal components in the vertical state can perform rust removal work on the transversely arranged U-shaped steel. The entire rust removal equipment is simple in design and can meet the rust removal operation of the transversely and vertically arranged U-shaped steel surface, further improving the working efficiency of the entire equipment.Specifically, the drive motor, heating wire, electric telescopic rod, and other components are all existing devices and well-known to those skilled in the art, so they will not be described in detail here. A main controller is installed on the equipment to control the opening and closing of the equipment. The controller is an existing control device and will not be described in detail here.

[0031] The suction chamber 16 is U-shaped with two ends, corresponding to two rows of suction heads 14. These two rows of suction heads 14 also correspond to the upper and lower ends of the wire brush plate 9, thus expanding the suction range and effectively ensuring suction performance. The telescopic pipe 17 connects the suction pipe 12 and the suction chamber 16. The telescopic pipe 17 is flexible, allowing it to extend and retract when the two opposing grinding seats 7 move relative to each other. This ensures that the suction pipe 12 and the suction chamber 16 remain connected. The auxiliary electric telescopic rod 19 directly drives the horizontal rust removal component to move, thus moving the horizontal rust removal component towards the other side of the U-shaped steel frame. The outer two sides are brought closer together. Normally, the auxiliary electric telescopic rod drives the transverse rust removal component to retract, ensuring that the longitudinal rust removal component can smoothly align with the two sides of the U-shaped steel. When the auxiliary electric telescopic rod 19 moves the transverse rust removal component, the designed L-shaped support rod 20 always slides and overlaps on the grinding seat 7 of the longitudinal rust removal component. Therefore, the L-shaped support rod 20 provides contact for the transverse rust removal component during sliding and provides support when not sliding, avoiding the auxiliary electric telescopic rod 19 providing sole support for the transverse rust removal component and ensuring support stability. The back of the wire brush plate 9 has an installation groove 32, so the heating plate 29 is directly inserted into the installation groove 32. At this time, the wire brush plate 9 and the heating plate 29... The mounting holes 33 on plate 29 correspond to each other and are fixed with mounting screws, so the wire brush plate 9 is detachable. If the wire brush plate 9 is damaged, it can be replaced with a new one. Before operation, the stability of the entire equipment installation must be checked. When the electric heating wire 31 is energized, the heating plate 29 generates heat, which is transferred to the wire brush plate 9, heating the parts that need rust removal. After heating, the steel parts are subjected to rust removal, and the rust on the surface of the reinforcing bars becomes loose and easier to remove, improving the rust removal efficiency of the device. Personnel can manually rotate the adjusting seat 4 of the longitudinal rust removal component. The configured bearings ensure the stability and smoothness of rotation, thus allowing the longitudinal and transverse rust removal components to move from... The horizontal mode can be switched to the vertical mode for rust removal of horizontally arranged U-shaped steel, further improving the overall efficiency of the equipment. In the vertical mode, the threaded holes 37 on the mounting plate 36 correspond one-to-one with the threaded holes 39. Screws and other installation tools can be inserted to fix the vertical and horizontal rust removal components. The electric pulleys 40 facilitate easy movement of the equipment, enabling better mobile rust removal of horizontal steel. When the equipment does not need to be moved, the manual turntable 26 can be manually rotated to contact the locking screw 27 with the ground, ensuring the stability of the equipment. The scale line 41 indicates the distance between two opposing grinding seats 7 after their relative movement.This allows for better rust removal of steel of varying thicknesses. It's important to note that the thickness of both sides of the steel should be measured beforehand, and the distance between the grinding pads 7 should be adjusted accordingly to ensure more precise contact and rust removal of the steel surface.

[0032] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
