Description

Technical Field

[0001] This utility model relates to the field of shipbuilding technology, and in particular to a ship hull paint maintenance device. Background Technology

[0002] Ships require paint for protection, and typically have their hulls repainted every three to five years. However, at sea, the hull is constantly in contact with highly corrosive seawater, causing areas where paint adhesion is poor to rust and peel off. Furthermore, during berthing, collisions with tugboats and dockworkers can further damage the hull, leading to paint loss and rust. If rust removal and repainting are neglected, the hull steel plates will gradually corrode and thin, posing a significant safety hazard to the ship.

[0003] If rust removal and painting are to be performed on the rusted parts of the ship's hull, personnel need to set up a plank, take precautions against falls, and work at heights outside the ship's hull, which carries a high risk. Moreover, the dangers of ships sailing at sea are extremely high, so overboard work is generally not permitted while the ship is underway, and therefore rust removal and painting maintenance cannot be carried out.

[0004] However, many ports now refuse to allow ships to have their hulls derusted and painted due to safety and pollution prevention concerns. Even if a port agrees to such work, the maintenance of the hull is very slow due to safety reasons. Since ships generally spend very little time in port now, the maintenance of ship hulls cannot be completed. Utility Model Content

[0005] This invention provides a ship hull paint maintenance device that can solve at least one of the above-mentioned technical problems.

[0006] To address the aforementioned technical problems, one or more embodiments of this utility model provide a ship hull paint maintenance device. The device has a first direction and a second direction perpendicular to each other. The maintenance device includes a frame, on which multiple electromagnets are mounted. A sliding assembly is mounted on the frame, and a worktable is mounted on the sliding assembly. The sliding assembly can drive the worktable to translate and position itself along the first and second directions respectively. Multiple telescopic components are mounted on the worktable. One end of each telescopic component is fixed to the worktable, and the other end extends towards the ship hull to be cleaned and is equipped with an execution component. The execution component is at least divided into a sanding component, a water spraying component, and a painting component.

[0007] The beneficial effects of one or more of the above technical solutions are as follows:

[0008] In this solution, an electromagnet is installed on the frame. This electromagnet can magnetically attract the frame and the entire maintenance equipment to the outer wall of the hull, thereby achieving a stable installation of the maintenance equipment outside the hull and preventing the swaying of the ship during navigation from affecting the ship's maintenance equipment.

[0009] In this solution, a sliding assembly is installed between the frame and the worktable. The worktable is equipped with grinding, water spraying, and painting components. The sliding assembly allows the worktable and the components to slide along a first and second direction to reach different rusted areas for rust removal, cleaning, and painting maintenance. Compared to existing technologies that rely on manual hull maintenance, this solution facilitates automated hull maintenance during sea voyages, reducing maintenance intervals and manpower requirements.

[0012] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0013] See Figure 1 This embodiment provides a ship hull paint maintenance device with a first direction and a second direction perpendicular to each other. The maintenance device includes a frame, on which multiple electromagnets 5 are mounted. A sliding assembly is mounted on the frame, and a worktable 1 is mounted on the sliding assembly. The sliding assembly can drive the worktable 1 to translate and position along the first direction and the second direction respectively. Multiple telescopic components 16 are mounted on the worktable 1. One end of the telescopic component 16 is fixed to the worktable 1, and the other end extends toward the ship hull to be cleaned and is equipped with an execution component. The execution component is at least divided into a sanding component 3, a water spraying component 11, and a painting component.

[0014] Specifically, four electromagnets 5 are installed at the four corners of the frame. When energized, these four electromagnets 5 magnetically adhere to the outer wall of the hull, and when de-energized, they separate the frame from the hull. Each of the four electromagnets 5 has a magnetic attraction surface, and all four face the same side of the frame. Therefore, when the hull's outer wall is flat, the magnetic attraction surfaces of the four electromagnets 5 are on the same plane.

[0015] When the frame and the entire maintenance equipment need to be attached to the curved surface of the ship's hull, it is not convenient for the electromagnet 5 to fully engage with the hull. In some embodiments, the electromagnet 5 is directly fixed to the frame, in which case the electromagnet 5 partially engages with the hull. In other structural configurations, a flexible seat is fixed between the electromagnet 5 and the frame. In this case, the electromagnet 5 is indirectly fixed to the frame through the flexible seat. Multiple electromagnets 5 can adjust the orientation of their engaging surfaces by deforming the flexible seat, thereby increasing the engaging area between the electromagnet 5 and the ship's hull.

[0016] In this embodiment, the sliding assembly includes a first motor 4, a first lead screw 10, and a first nut seat 7. The frame includes a crossbeam 12. The first lead screw 10 and the crossbeam 12 extend along a first direction. The first lead screw is supported by the crossbeam 12. The first nut seat 7 is slidably connected to the crossbeam 12. The worktable 1 is supported by the first nut seat 7. The first motor 4 and the first lead screw 10 can drive the first nut seat 7 and the worktable 1 to translate along the first direction.

[0017] Specifically, the housing of the first motor 4 is fixed to one end of the crossbeam 12, and the other end of the crossbeam 12 is provided with a first support 13. One end of the first lead screw 10 is rotatably connected to the drive shaft of the first motor 4 through a coupling 6, and the other end is rotatably connected to the support 13. The support 13 is fixed to the crossbeam 12.

[0018] In this embodiment, the sliding assembly also includes a second lead screw 8 and a second nut seat 2 extending along the second direction. The second lead screw 8 is supported by a first nut seat 7, and the second nut seat 2 is fixed to the worktable 1. The second lead screw 8 can drive the second nut seat 2 and the worktable 1 to translate along the second direction.

[0019] In this embodiment, there are two second lead screws 8. The second lead screws 8 span two crossbeams 12. One end of the second lead screw 8 is rotatably connected to the rotating seat 9, and the other end is driven by the second motor 15. The rotating seat 9 and the second motor 15 are respectively fixed by the first nut seat 7 on the two crossbeams 12.

[0020] In this embodiment, there are two crossbeams 12, and the two crossbeams 12 are arranged side by side along the second direction, and the two crossbeams 12 are connected by an auxiliary rope 17.

[0021] Specifically, a first lead screw 10 is installed on each crossbeam 12, and two first nut seats 7 are installed on each first lead screw 10. At this time, a total of four first nut seats 7 are set on the frame.

[0022] See Figure 1 The first nut seat 7 on one of the crossbeams 12 is used to support and install the second motor 15, and the first nut seat 7 on the other crossbeam 12 is used to support and fix the rotating seat 9.

[0023] This embodiment includes five telescopic components 16 and five actuating components, all of which are electric push rods. The worktable 1 is square, and one of the aforementioned telescopic components 16 is installed at each of the four corners along the first and second directions and at the center of the worktable 1. More specifically, the five actuating components are a first topcoat painting component 18, a second topcoat painting component 14, a rust-preventive painting component 19, a water spraying component 11, and a polishing component 3.

[0024] In this embodiment, the axis of the roller brush in the first topcoat painting assembly 18 is parallel to the first direction, and the axis of the roller brush in the second topcoat painting assembly 14 is parallel to the second direction.

[0025] Specifically, the painting assembly also includes a paint bucket (not shown in the figure), which is connected to one end of a pipe and the other end of the pipe is positioned opposite the roller brush. A pump is installed on the pipe to supply paint from the paint bucket to the roller brush.

[0026] To distinguish them, the paint bucket in the anti-rust coating assembly 19 contains anti-rust paint, while the paint buckets in the first topcoat coating assembly 18 and the second topcoat coating assembly 14 contain topcoat.

[0027] Specifically, the grinding assembly 3 includes a grinding wheel (not shown in the figure) and a motor (not shown in the figure). The motor is fixed to the worktable 1, and the output shaft of the motor is coaxially fixed to the grinding wheel.

[0028] The water spray assembly 11 here includes a water supply line, a high-pressure water pump, and a nozzle (not shown in the figure).

[0029] In other embodiments, the specific structural forms of the first painting component, the second painting component, the water spraying component 11, and the sanding component 3 can be set by those skilled in the art, and will not be described in detail here.

[0030] In this embodiment, a camera component is installed on the workbench 1, which can transmit images of the ship's hull to a remote display terminal.

[0031] Working principle: When using this device, it is hoisted to the working position using a mobile cargo crane on the ship and slings and ropes. When the electromagnet 5 is energized, the worktable 1 is attracted to the hull plate.

[0032] The first motor 4 and the first lead screw 10 drive the first nut seat 7, which in turn drives the second lead screw 8, the worktable 1, and the actuator to move left and right. The second motor 15 and the second lead screw 8 drive the second nut seat 2 and the worktable 1 to move up and down. When the worktable 1 is moved to the area requiring rust removal and maintenance, the grinding assembly 3 is powered on, and the grinding wheel of the grinding assembly 3 is pressed tightly against the hull plate. At the same time, the motor is powered on to perform the rust removal operation. Using dynamic image transmission from a camera, the rotation of the first lead screw 10 and the second lead screw 8 is remotely controlled, causing the grinding wheel to move up, down, left, and right within the worktable 1 to perform the rust removal operation. After grinding, the grinding area is washed and cleaned with water using the water spray assembly 11.

[0033] After the sanding area is washed and dried, the anti-rust coating component 19 is powered on. The telescopic component 16 presses the roller brush of the anti-rust coating component 19 firmly against the hull plate, and the control platform moves up, down, left, and right to apply the anti-rust paint to the hull plate first. After the anti-rust paint dries, the first topcoat coating component 18 and the second topcoat coating component 14 are powered on in the same way and remotely controlled so that their roller brushes can move up, down, left, and right within the range of the worktable 1 to apply the topcoat to the hull plate.

[0034] The above specific embodiments should not be construed as limiting the scope of protection of this utility model. For those skilled in the art, any alternative improvements or modifications made to the embodiments of this utility model shall fall within the scope of protection of this utility model.

[0035] Any aspects of this utility model not described in detail are known to those skilled in the art.
