Description

Technical Field

[0001] The invention belongs to the technical field of ship maintenance, and in particular relates to automatic rust removal equipment based on a ship deck. Background Art

[0002] When ships operate in marine environments, their deck surfaces are susceptible to moisture, high salt spray, and other factors, leading to corrosion. To ensure the structural strength and safety of ships, decks must be regularly derusted. Existing rust removal operations primarily rely on manual derusting tools or simple semi-automatic equipment. These processes are labor-intensive, inefficient, and have inconsistent quality, especially when operating over large areas.

[0003] In traditional technology, although some portable rust removal equipment is equipped with electric drive units and grinding components, most of the equipment has a fixed grinding depth and cannot automatically adjust the degree of pressure of the grinding wheel according to the undulations of the deck, which can easily lead to uneven grinding or equipment damage. In addition, the movement method usually relies on manual pushing and pulling, which is unstable in direction and difficult to operate accurately along the wall or edge area, resulting in blind spots at the edge of rust removal. At the same time, in order to improve the dust reduction and cooling effect during operation, some equipment is equipped with a water spray mechanism, but common water spray devices require manual control of opening and closing, and do not have automatic linkage functions. It is easy to waste water resources or delay water spraying, affecting operation efficiency.

[0004] In summary, existing deck rust removal equipment still has specific technical problems in the following aspects: First, the up and down adjustment of the rust removal grinding wheel relies on manual adjustment and cannot automatically adapt to the undulations of the deck surface, which poses a risk of uneven grinding or equipment collision; second, the direction control of the equipment is not flexible when moving, especially when working along the wall, it is difficult to maintain straight operation, which affects the rust removal coverage; third, the water spraying device cannot be synchronized with the opening and closing status of the equipment, resulting in water leakage and waste or untimely spraying.

[0018] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following examples. It should be understood that the following text is only used to describe one or more specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention. Example 1

[0019] See Figure 1-9 , an automated rust removal device based on a ship deck, comprising a mobile support structure 1, the mobile support structure 1 comprising a base plate 11, a triangular plate 12 is provided at the bottom of the base plate 11, the triangular plates 12 are equilaterally distributed and are used to support the entire device and enhance stability, a roller 13 is provided at the bottom of the triangular plate 12, one of the rollers 13 is a universal wheel, which is used to improve the steering flexibility of the device; three support columns 14 are provided on the top of the base plate 11, and the three support columns 14 are equilaterally distributed to ensure uniform load-bearing of the upper components, and an upper shell 15 is installed on the top of the three support columns 14, and the upper shell 15 serves as a closed structure of the entire device for carrying core power components such as a motor 17 and a rotating shaft 18; the support column 1 A shaft sleeve 16 is rotatably mounted below the surface of the deck 11, and is used to support and limit the annular turntable 21 of the rotation mechanism. A grinding wheel anti-collision mechanism 2 is rotatably mounted on the outer side of the base plate 11. The grinding wheel anti-collision mechanism 2 controls the raising and lowering of the grinding wheel 27 through an internal transmission component to adapt to deck surfaces of different heights. At the same time, a chamfered structure is provided on the outer side of the grinding wheel 27 to prevent direct collision between the grinding wheel 27 and protrusions on the deck and cause damage. The overall structure of the equipment can be manually guided and moved by a control rod 110. When not in operation, the grinding wheel 27 is in an elevated state to facilitate the smooth sliding of the equipment. The mutual cooperation of multiple groups of structural components improves the stability, ease of operation and rust removal adaptability of the equipment during operation.

[0020] The grinding wheel anti-collision mechanism 2 includes an annular turntable 21 rotating on the outside of the three shaft sleeves 16. The bottom of the annular turntable 21 is supported by the base plate 11, and the bottom adopts a sliding contact structure to maintain stability during rotation; the upper surface of the annular turntable 21 is recessed downward to form an accommodating space for installing structural components such as the track rod 23 and the slider 25; the upper shell 15 seals the top of the annular turntable 21 to form a closed cavity for dust prevention and structural stability; a plurality of grinding wheels 27 are evenly and slidably installed on the bottom of the annular turntable 21, and the grinding wheel 27 is installed at the bottom of the slide rod 26 and can automatically press down to grind the rusted parts of the deck according to the centrifugal force and the inclined surface linkage structure. The downward pressure is always maintained during the grinding process to ensure the strength and consistency of rust removal.

[0021] Edge movement auxiliary mechanisms 3 are evenly installed on the surface of the upper shell 15. The edge movement auxiliary mechanisms 3 are used to assist the equipment to move in a straight line when removing rust from the edges and corners of the plywood. The auxiliary mechanism adopts a rotating ring 31 structure, and a stable guide device is formed by an extension rod 32 and an auxiliary wheel 33. The auxiliary wheel 33 slightly exceeds the rotation radius of the grinding wheel 27 to avoid interference between the grinding wheel 27 and the deck wall, thereby ensuring the safety and comprehensiveness of the grinding corner position.

[0022] An automatic water outlet mechanism 4 is installed at the lower part of the bottom plate 11. The automatic water outlet mechanism 4 is used to automatically discharge water when the equipment is turned on. The automatic water outlet mechanism 4 drives the sliding sleeve 46 to lift the sealing ring 45 through the power shaft 44 to make the water outlet pipe 43 unobstructed, forming a linkage control structure. When the equipment is turned off, the sliding sleeve 46 stops moving up, and the sealing ring 45 automatically moves down to block the entrance of the water outlet pipe 43, effectively preventing leakage and waste of clean water, and at the same time realizing intelligent switching between the operating state and the non-operating state, thereby improving the dust removal and cooling effect during the deck grinding process.

[0023] See Figure 1-2 , rollers 13 are installed at the triangular parts at the bottom of the triangular plate 12, one of the three rollers 13 is a universal wheel, which is used for flexible steering control of the equipment on the horizontal plane; a control rod 110 is installed on the side of the top of the upper shell 15 away from the universal wheel. The control rod 110 is connected to the top of the upper shell 15 structure and extends outside the body for manual pushing and pulling of the equipment to achieve overall movement. In the non-rust removal operation state, the grinding wheel 27 floats up and the roller 13 becomes the main support point, thereby ensuring the smooth movement of the equipment.

[0024] See Figure 1-4 , the inner ring surface of the annular turntable 21 is evenly provided with internal tooth grooves 22 along the axis, and the internal tooth grooves 22 are meshed with gears 181 to achieve power transmission and stable rotation of the annular turntable 21; a motor 17 is fixed to the top center of the upper shell 15, and the output end of the motor 17 is connected to the rotating shaft 18 arranged below through a transmission belt 19. The rotating shaft 18 passes vertically through the upper shell 15 and is rotatably installed on one side of its lower surface. A gear 181 is provided at the bottom of the rotating shaft 18, and the gear 181 is located on the inner side of the annular turntable 21 and is precisely meshed with the internal tooth grooves 22. The rotation function of the entire annular turntable 21 is realized by driving the motor 17.

[0025] See Figure 1-5A plurality of groups of track rods 23 are evenly arranged inside the annular turntable 21, and each group is provided with two track rods 23. The two track rods 23 are arranged in parallel and are used for slidingly installing a slider 25. The slider 25 is used to move outward in response to the centrifugal force generated during the rotation of the annular turntable 21. An extrusion protrusion 251 is provided at the bottom of the slider 25. The extrusion protrusion 251 is used to contact the inclined surface at the top of the extrusion block 28 and realize the linkage downward movement. Fixed cylinders 24 are evenly arranged at the bottom of the annular turntable 21. The fixed cylinders 24 are used to install components such as slide rods 26 and springs 29. The positions of the fixed cylinders 24 correspond one by one to the track rods 23 to constitute a mechanical transmission unit.

[0026] See Figure 3-5 A slide bar 26 is installed vertically slidingly inside the fixed cylinder 24, and a grinding wheel 27 is fixedly installed at the lower end of the slide bar 26. The grinding wheel 27 can float up and down under the drive of the slide bar 26 to adapt to deck surfaces of different heights. An extrusion block 28 is connected to the top of the slide bar 26. The extrusion block 28 is a square structure to achieve stable lifting. The top of the extrusion block 28 is provided with an inclined surface on the side facing the center of the annular turntable 21, which is used to contact the extrusion protrusion 251 on the slider 25. When the slider 25 moves outward due to centrifugal force, an extrusion force is formed on the inclined surface of the extrusion block 28, driving the extrusion block 28 to move downward as a whole; a spring 29 is provided on the outer surface of the slide bar 26, which is installed on the inner side of the fixed cylinder 24 and applies an upward reset thrust to the extrusion block 28, which is used to lift the grinding wheel 27 to a non-contact state after the equipment stops rotating, so as to avoid interference and loss during movement.

[0027] See Figure 3-7 The outer circular surface of the upper shell 15 is evenly provided with positioning holes 151, and the positioning holes 151 are used to assist in the precise fixation of the angle of the edge line movement auxiliary mechanism 3; the edge line movement auxiliary mechanism 3 includes a rotating ring 31 rotating on the surface of the upper shell 15, and the rotating ring 31 can be rotated and adjusted within a certain angle range relative to the upper shell 15; positioning bolts 34 are symmetrically arranged on both sides of the rotating ring 31, and the positioning bolts 34 pass through the rotating ring 31 and are adapted to the positioning holes 151. The angle of the rotating ring 31 can be locked and fixed by tightening, so as to achieve a reliable guiding effect when the equipment needs to grind along the edge in a straight line.

[0028] See Figure 7 An extension rod 32 is symmetrically provided on one side of the rotating ring 31. An auxiliary wheel 33 is installed at the end of the extension rod 32 through a rotating connection. The rotation axis direction of the auxiliary wheel 33 is vertically arranged. The auxiliary wheels 33 are installed at both ends of the rotating ring 31. The two auxiliary wheels 33 are positioned toward the deck wall. The outermost wheel edge slightly protrudes from the rotating outer edge of the grinding wheel 27, which is used to provide physical isolation protection when the grinding equipment approaches the corner of the deck or the edge of an obstacle, preventing the side of the grinding wheel 27 from directly contacting the obstacle.

[0029] See Figure 2 、 Figure 8 and Figure 9 The automatic water outlet mechanism 4 includes a water tank 41 fixedly installed in the center of the bottom plate 11. The water tank 41 is a closed hollow structure for storing clean water; a water injection pipe 42 is provided above one side of the water tank 41, and the water injection pipe 42 passes through the top of the upper shell 15 for external water injection or connection to an external water source; a plurality of water outlet pipes 43 are evenly arranged below the surface of the water tank 41, and the water outlet pipes 43 are distributed toward the bottom of the triangular plate 12. The plurality of water outlet pipes 43 are respectively provided with openings to ensure that the clean water is evenly distributed and sprayed out, which is used to meet the dust removal and cooling needs of the grinding wheel 27 during the grinding process.

[0030] See Figure 1 、 Figure 8 and Figure 9 The output shaft of the motor 17 is equipped with a power shaft 44, which vertically passes through the bottom plate 11 and extends to the bottom of the water tank 41; a sealing ring 45 is provided inside the water tank 41, and the sealing ring 45 is installed around the upper opening of the water outlet pipe 43 to block the water path in the closed state; a sliding sleeve 46 is installed below the surface of the power shaft 44, and the sliding sleeve 46 is connected to the sealing ring 45 through an internally arranged fixing rod to form an integrated linkage structure; an arc-shaped cam groove 441 is provided below the surface of the power shaft 44, and the arc-shaped cam groove 441 is used to realize the axial lifting of the sliding sleeve 46; a fixing bolt 461 is provided on the inside of the sliding sleeve 46, and the fixing bolt 461 is slidably embedded in the arc-shaped cam groove 441. As the power shaft 44 rotates, the fixing bolt 461 drives the sliding sleeve 46 to move upward, thereby realizing the opening of the sealing ring 45 and automatic water outlet control. Example 2

[0031] See Figure 1-5 、 Figure 3-5 In this embodiment, the track rod 23, the fixed cylinder 24 and the slide rod 26 are made of Q235 cold-rolled steel plate to enhance their strength and wear resistance under high-speed rotation conditions; the slider 25 is injection-molded with polyoxymethylene (POM) material and has an integrally formed extrusion protrusion 251 at its bottom. The extrusion protrusion 251 is used to generate contact force with the inclined surface of the top of the extrusion block 28; the extrusion block 28 is made of 45# steel that has been quenched and processed into an inclined surface transition structure. The surface of the slide rod 26 is provided with a spring 29, which is a stainless steel compression spring. In the inner cavity of the fixed cylinder 24, it is used to reset the grinding wheel 27 upward; the grinding wheel 27 is a vitrified bond grinding wheel with chamfers and has a size of Φ100×15mm; during operation, the motor 17 drives the rotating shaft 18 to rotate the annular turntable 21 through the engagement of the gear 181. When the turntable 21 rotates at high speed, the slider 25 slides outward along the track rod 23 due to centrifugal force, thereby causing the extrusion protrusion 251 to press the extrusion block 28 downward, thereby driving the slide bar 26 and the grinding wheel 27 to descend and contact the deck for rust removal; when the motor 17 stops running, the spring 29 resets and drives the grinding wheel 27 to move upward to avoid collision.

[0032] In traditional rust removal equipment, the grinding wheel is installed at a fixed height on the end of the motor shaft and has no automatic lifting structure. It needs to rely on manual adjustment or pre-set height. When the deck is convex or uneven, it is very easy to cause uneven grinding or equipment damage. In contrast, the grinding wheel in this embodiment can automatically adjust the height according to the centrifugal force and the linkage of the inclined surface, and always maintain downward pressure to ensure the grinding quality and improve the adaptability and safety of the equipment. Example 3

[0033] See Figure 3-7 、 Figure 7 In this embodiment, the rotating ring 31 is integrally cast from an aluminum alloy and tightly fits the outer surface of the upper shell 15 to form an adjustable positioning structure. Positioning bolts 34 with M8 thread specifications are provided on both sides of the rotating ring 31. The bolts 34 match the positioning holes 151 evenly opened on the upper shell 15. There are 12 positioning holes 151, one hole is provided every 30°, for fixing different auxiliary guide angles. Two steel extension rods 32 extend from the rotating ring 31, and auxiliary wheels 33 are installed at the ends of the rods through rolling bearings. The tires of the auxiliary wheels 33 are made of polyurethane material, and the axial direction is arranged perpendicular to the base plate 11. The overall height is about 2 mm above the outer edge of the grinding wheel 27. During rust removal operations along the wall, the operator rotates the rotating ring 31 until the auxiliary wheels 33 face the wall side and fix them with the positioning bolts 34. The control rod 110 is used to push the device forward along the edge. The auxiliary wheels 33 are close to the wall to provide a smooth guide, thereby enabling the grinding wheel 27 to achieve maximum working coverage while avoiding deviation.

[0034] When existing equipment approaches the edge of the deck or an obstacle wall, the operator has difficulty controlling the equipment's forward direction due to the lack of a dedicated guide structure, which can easily lead to deviation from the running trajectory or collision of the grinding wheel with the wall. In contrast, this embodiment ensures the edge stability of the equipment through the edge auxiliary wheel structure, and structurally makes the auxiliary wheel slightly protrude beyond the grinding wheel's rotation radius, effectively forming a protective boundary, improving the rust removal integrity and the safety of edge and corner operations. Example 4

[0035] See Figure 1 、 Figure 2 、 Figure 8 and Figure 9In this embodiment, a stainless steel welded water tank structure is used as the water tank 41 with a capacity of 1.5 liters. The water injection pipe 42 is a PVC transparent hose that passes through the top of the upper shell 15 to connect to the municipal water source or artificial water injection. There are three water outlet pipes 43, which are evenly arranged at the bottom of the water tank 41 and have a hole diameter of Φ5mm. The output shaft end of the motor 17 is connected to the power shaft 44. The power shaft 44 is a solid carbon steel shaft and passes through the bottom of the water tank 41. The middle of the power shaft 44 is connected to a nylon sleeve 46. The sleeve 46 is connected to the silicone by two stainless steel connecting rods. The power shaft 44 is circumferentially machined with an arc-shaped cam groove 441, and a stainless steel fixing bolt 461 is embedded in the inner side of the sliding sleeve 46, which is engaged with the arc-shaped cam groove 441; when the motor 17 is running, the power shaft 44 drives the fixing bolt 461 to move along the arc-shaped groove track, thereby driving the sliding sleeve 46 to move upward, so that the sealing ring 45 is separated from the outlet of the water outlet pipe 43 to form a water outlet state; when the motor stops running, the sliding sleeve 46 falls back under the action of gravity and water pressure, and the sealing ring 45 blocks the water outlet to stop water outlet.

[0036] The water spraying system in traditional equipment usually adopts manual switches or individually controlled solenoid valves, which have problems such as untimely control, unstable water pressure, and waste caused by continued water discharge after operation is interrupted. In comparison, this embodiment uses the power shaft to link the sliding sleeve and sealing ring structure, and utilizes the automated logic of linkage water spraying when the equipment starts and sealing when it stops, effectively achieving the dust removal and cooling control and water saving goals, and improving the level of intelligence and resource utilization efficiency.

[0037] The working principle of the present invention is as follows: when not started, due to the presence of multiple springs 29, the extrusion block 28 is placed at the top of the stroke, and then the slider 25 is pushed in the opposite direction along the trajectory of the track rod 23 to a position closer to the center. At this time, the bottom of the grinding wheel 27 is higher than the roller 13 to facilitate the movement of the equipment. When moving, the equipment can be pushed or pulled by the control rod 110. The one of the three rollers 13 that is away from the control rod 110 is a universal wheel to facilitate the steering of the equipment through the control rod 110. When working, the motor 17 is started, and the rotation of the motor 17 can drive the rotating shaft 18 to rotate at high speed through the transmission belt 19, and then the annular turntable 21 is driven to rotate through the engagement of the gear 181 and the inner tooth groove 22. The inner side of the annular turntable 21 is supported by three shaft sleeves 16 The bottom is supported by the bottom plate 11 to ensure its stability during rotation. When the annular turntable 21 rotates, the centrifugal force forces the slider 25 to move outward along the trajectory of the track rod 23, and then the extrusion block 28 is squeezed by the extrusion protrusion 251 on the inclined surface of the extrusion block 28, causing the extrusion block 28 to move downward. The cross-section of the extrusion block 28 is square, so that it can move up and down. The downward movement of the extrusion block 28 can drive the grinding wheel 27 to move downward until the bottom contacts the deck surface, thereby grinding and removing rust by rotation. During this process, the grinding wheel 27 is always under downward pressure to ensure its grinding force. When there is a protruding foreign object on the deck, the outer side of the bottom of the grinding wheel 27 is provided with a chamfer, which can force the grinding wheel 27 to move upward to prevent it from colliding with the protrusion and causing damage.

[0038] When it is necessary to grind the position along the wall, the angle of the rotating ring 31 can be adjusted so that the two auxiliary wheels 33 are placed on the side facing the wall and fixed by the positioning bolts 34 on both sides and the positioning holes 151. At this time, pushing the device to move can make the auxiliary wheels 33 move along the wall, thereby assisting the device to move in a straight line along the wall. The outermost side of the grinding wheel 27 is flush with the outer surface of the annular turntable 21 to achieve maximum grinding range, and the auxiliary wheel 33 slightly extends beyond the rotating outer ring of the grinding wheel 27 to prevent the side of the grinding wheel 27 from contacting the wall.

[0039] When the water tank 41 is not started, the sealing ring 45 is placed at the bottom of the water tank 41 due to its own weight, and then the water inlets of the multiple water outlet pipes 43 are blocked to prevent water leakage. On the contrary, when the device is started, the power shaft 44 will also rotate. When the power shaft 44 rotates, the fixing rod between the sealing ring 45 and the sliding sleeve 46 is subjected to the resistance of the water, and the sliding sleeve 46 cannot immediately rotate with the power shaft 44. At this time, the sliding sleeve 46 can be driven to move upward by the matching of the arc cam groove 441 and the fixing bolt 461, so that the fixing bolt 461 cannot continue to move upward when it moves to the top of the arc cam groove 441. At this time, the sliding sleeve 46 will rotate together with the power shaft 44, but the upward movement of the sliding sleeve 46 will drive the sealing ring 45 upward, so that the water in the water tank 41 flows out through the water outlet pipe 43 to achieve the effect of dust removal and cooling, thereby achieving water outlet when the device is turned on and the water flow is automatically shut off when the device is turned off, thereby preventing water waste.
