Description

Technical Field

[0001] This utility model relates to the treatment of ship steel, specifically to a rust removal device for steel plates used in ship repair and construction. Background Technology

[0002] As a crucial tool for maritime transportation and operations, a ship's structure is primarily composed of a series of plates and a frame. These plates and the frame are tightly connected and mutually supportive. The frame, acting as the hull's supporting structure, not only significantly improves the strength and rigidity of the hull plates but also greatly enhances their resistance to instability. In shipbuilding, steel plates are an indispensable basic material, and their quality directly affects the ship's overall performance and service life.

[0003] During the production, processing, and long-term storage of steel plates, their surfaces are highly susceptible to rust due to environmental factors. The presence of rust weakens the strength of the steel plates, reduces their corrosion resistance, and consequently affects the safety performance and service life of ships. Therefore, effectively removing rust from the surface of steel plates is a crucial step in shipbuilding and repair.

[0004] Traditional steel plate rust removal equipment mostly relies on manual operation, which has many drawbacks. Firstly, manual rust removal is extremely inefficient, failing to meet the large-scale, high-efficiency production demands of modern shipbuilding and repair. Secondly, manual operation is extremely labor-intensive, severely depleting the physical strength of workers. Furthermore, the effectiveness of manual rust removal varies greatly, largely depending on the worker's experience and skill level, making it impossible to guarantee the stability and consistency of rust removal quality and meet the high standards required for steel plate rust removal in shipbuilding and repair. In addition, the large amount of rust dust generated during manual rust removal severely pollutes the working environment and endangers the health of operators.

[0005] With the rapid development of the shipbuilding industry, higher requirements have been placed on the rust removal technology of steel plates used in shipbuilding and repair. Developing a high-efficiency, environmentally friendly, highly automated, and stable rust removal device for steel plates has become an important problem that urgently needs to be solved in the shipbuilding and repair field.

[0028] To fully understand this utility model, detailed steps and structures will be presented in the following description to illustrate the technical solution of this utility model. Preferred embodiments of this utility model are described in detail below; however, in addition to these detailed descriptions, this utility model may have other embodiments.

[0029] Reference Figure 1-4 As shown, this utility model provides a rust removal device for steel plates used in shipbuilding and repair. The device mainly consists of a mobile trolley 1 and several functional components, designed to efficiently and conveniently remove rust from the surface of steel plates during shipbuilding and repair. The mobile trolley 1 serves as the carrier of the entire device, with two sets of wheels at the bottom. A handle is installed at the rear of the mobile trolley 1, allowing operators to easily push or pull the trolley, thus enabling the device to be moved and effectively reducing the labor intensity of the operators.

[0030] The front end of the mobile cart 1 is equipped with an upper box 6, a dust cover 7, and a rust removal component 8. The upper box 6 is fixed to the front end of the mobile cart 1, and the dust cover 7 with its opening facing downward is fixedly installed at the bottom of the upper box 6. Its main function is to prevent rust dust from flying around during the rust removal process, effectively control dust pollution, and protect the working environment and the health of the operators.

[0031] The rust removal component 8 includes a power shaft 12 that passes vertically through the upper housing 6 and the dust cover 7. A drive component is provided on the top plate of the upper housing 6 and is connected to the top of the power shaft 12. A grinding wheel 14 is detachably installed at the bottom of the power shaft 12. The grinding wheel 14 is a component that directly contacts the surface of the steel plate to perform rust removal. The detachable design makes it convenient to select the appropriate grinding wheel according to different steel plate materials and rust levels. At the same time, the grinding wheel can be replaced in time after it wears out, reducing maintenance costs.

[0032] A worm gear 19 is located in the middle of the power shaft 12. A gearbox 4, located behind the upper housing 6, is mounted on the mobile trolley 1 via a support frame 3. A transmission rod 21 is connected to the gearbox input shaft 41, and a transmission gear 20 meshing with the worm gear 19 is fixed to one end of the transmission rod 21. When the power shaft 12 rotates, the worm gear 19 rotates accordingly, thereby driving the transmission gear 20 and the transmission rod 21 to rotate, transmitting power to the gearbox 4. The output shaft of the gearbox 4 is connected to a set of traveling wheels via a belt, allowing the power of the rust removal components to drive the traveling wheels, enabling automatic movement of the device during the rust removal process, reducing manual pushing and improving work efficiency.

[0033] A dust collection assembly 2 is also installed on the mobile cart 1. The dust collection assembly 2 includes a suction head 15, a connecting hose 16, a dust pump 17, and a dust collection box 18. The dust collection box 18 is fixedly installed on the mobile cart 1, providing storage space for collecting rust dust. The dust pump 17 serves as the power source for the dust collection assembly. Its air inlet side is connected to the suction head 15 via the connecting hose 16. The suction head 15 is fixed inside the dust cover 7, enabling it to promptly extract rust dust generated during the rust removal process. The air outlet side of the dust pump 17 is connected to the dust collection box 18 via a pipe, transporting the extracted rust dust to the dust collection box 18 for collection. The dust collection box 18 has an exhaust port, on which a metal filter is magnetically installed. The metal filter effectively filters out fine dust particles in the exhaust air, preventing secondary pollution to the environment. The magnetic installation method also facilitates the removal and cleaning of the filter.

[0034] In an optional embodiment, the drive component includes a drive motor 9, a main gear 10, and a driven gear 11, which mesh with each other. The main gear 10 is fixed on the output shaft of the drive motor 9, and the driven gear 11 is fixed on the top end of the power shaft 12.

[0035] In an optional embodiment, the upper housing 6 and dust cover 7 are equipped with multiple rotating bearings (not shown in the figure) on the same vertical line. The power shaft 12 passes through each rotating bearing in sequence and is rotatably connected. The arrangement of rotating bearings can effectively reduce the friction force when the power shaft 12 rotates, reduce energy loss, improve power transmission efficiency, and at the same time ensure the stability of the power shaft 12 during rotation, avoid wobbling or deviation, and ensure that the grinding wheel 14 can uniformly remove rust from the steel plate surface.

[0036] In an optional embodiment, a positioning plate 13 is fixedly connected to the bottom of the power shaft 12, and the grinding wheel 14 is mounted on the bottom of the positioning plate 13 by a plurality of fastening bolts.

[0037] In an optional embodiment, a sliding sleeve 5 is slidably connected between the gearbox input shaft 41 and the drive rod 21. The sliding sleeve 5 allows for the connection or disconnection of the gearbox input shaft 41 and the drive rod 21. When rust removal is required, the mobile trolley 1 is moved forward, and the gearbox input shaft 41 and the drive rod 21 are connected by sliding the sliding sleeve 5 forward (e.g., ...). Figure 4 (As shown in Figure a); when the steel requires deep rust removal, slide the sliding sleeve 5 backward to disconnect the connection between the gearbox input shaft 41 and the transmission rod 21 (as shown in Figure a). Figure 4(As shown in Figure b), the rust removal component 8 remains operational while the moving trolley 1 remains stationary. It should be noted that before sliding the sliding sleeve 5, the rust removal component 8 must be stopped first. If the sliding sleeve 5 cannot be inserted into the outer hexagon of the transmission rod 21 after complete stopping, the trolley can be slightly pushed to rotate the gearbox input shaft 41 so that the gearbox input shaft 41 and the outer hexagon of the transmission rod 21 coincide axially. Then, slide the sliding sleeve 5 and insert it into the outer hexagon of the transmission rod 21. It should be noted that to prevent the sliding sleeve 5 from disengaging from the transmission rod 21 during rotation, the sliding sleeve 5 needs to have a certain length to ensure that the gearbox input shaft 41 and the transmission rod 21 are inserted into the sliding sleeve 5 to a certain depth, effectively preventing the sliding sleeve 5 from disengaging during rotation.

[0038] In an optional embodiment, the other end of the transmission rod 21 and the gearbox input shaft 41 are both provided with external hexagons, and the sliding sleeve 5 is provided with internal hexagon through holes that cooperate with the external hexagons. This ensures that the sliding sleeve 5 is accurately connected to the transmission rod 21 and the gearbox input shaft 41 during the sliding process, and that there is no slippage during the transmission process, thus ensuring the reliability of power transmission.
