Description

Technical Field

[0001] This utility model relates to the technical field of rust removal mechanisms, and in particular to a rust removal mechanism for ship decks. Background Technology

[0002] During operation, ships are constantly immersed in seawater. Influenced by factors such as seawater temperature, salinity, and the temperature and humidity of the marine atmosphere, the steel materials undergo electrochemical corrosion, leading to oxidation and rust on the hull surface. Over time, severe rust inevitably develops on ships, affecting not only their lifespan but also potentially damaging the hull structure and consequently impacting safe operation. Therefore, regular rust removal and maintenance are crucial. Rust removal includes not only the outer walls but also the decks. Traditional rust removal methods often involve manually spraying dilute inorganic acid solutions and then scrubbing. However, this method is ineffective when dealing with deck gaps, as wastewater tends to accumulate in the gaps, making it difficult to observe rust and resulting in incomplete rust removal. Patent publication number CN219212698U discloses a ship deck rust removal device, including a rust removal machine body and a handrail fixed to its surface. A drive shaft is installed at the bottom of the rust removal machine body, driven by a motor inside the machine body. Universal wheels are fixed at the four corners of the bottom of the rust removal machine body, and a mounting frame is fixed at the top of the machine body. A display is mounted on the inner wall of the mounting frame via a damping hinge. Conduits are fixed on both sides of the rust removal machine body, and mounting plates are fixed at the bottom of each of the two conduits. Cameras are mounted on the surfaces of the two mounting plates via damping hinges. By installing two cameras at the bottom of the rust removal machine body, with the cameras positioned on the front and rear sides of the grinding mechanism respectively, the operator can clearly observe the location of the rust in front of the grinding mechanism through the monitor when the rust removal machine body is moved by pushing the handle, and can also observe the condition of the deck after grinding.

[0003] In the above-mentioned solution, no locking mechanism is set during the lifting and lowering of the protective sleeve. The rust removal effect is not good for decks with different degrees of rust. In the actual rust removal process, the friction physical rust removal method requires the use of rust removal liquid to cool the friction disc or chemically erode the rust stains in order to enhance the rust removal effect of the equipment. Therefore, this utility model proposes a marine deck rust removal mechanism to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to solve the technical problems mentioned in the background art.

[0005] The present invention adopts the following technical solution: a marine deck rust removal mechanism, comprising a rust removal component, the rust removal component comprising a support column, a locking drive mechanism disposed above the support column, a lifting mounting ring rotatably connected below the support column, a spraying mechanism rotatably connected to the lifting mounting ring, a lifting gear ring threadedly connected below the support column, a connecting ring disposed at the bottom of the lifting gear ring, a protective sleeve fixed at the bottom of the connecting ring, an mounting plate fixed at the bottom of the support column, and a friction disc disposed at the bottom of the mounting plate.

[0006] Preferably, the rust removal component is fixed to the bottom of the rust removal machine body, wheels are provided at the four corners of the bottom of the rust removal machine body, and a camera device is fixed to the top of the rust removal machine body. Here, four wheels are provided to support and facilitate the movement of the rust removal mechanism.

[0007] Preferably, the locking drive mechanism includes an upper mounting plate, a motor shaft support sleeve fixed to the bottom of the upper mounting plate, a motor shaft slidably connected below the motor shaft support sleeve, and a drive gear fixedly connected to the drive gear, which is rotatably connected to the lower motor. Here, the drive gear meshes with the lifting gear ring, and the motor rotation drives the lifting gear ring to rise or fall along the support column, which can also lock the lifting gear ring.

[0008] Preferably, the upper mounting plate is mounted on the support column by locating pins, and the motor is fixedly mounted on the protective sleeve. Here, two locating pins are provided, located on the left and right sides of the upper mounting plate respectively, which facilitates the positioning of the motor shaft during disassembly.

[0009] Preferably, the spraying mechanism includes a support arm mounting ring, a support arm mounting seat fixed on the support arm mounting ring, a support arm connected to the support arm mounting seat, a nozzle mounting block at the bottom of the support arm, a support arm mounting seat fixed at the top of the nozzle mounting block, and the support arm connected to the nozzle mounting block via the support arm mounting seat on the nozzle mounting block. A nozzle is internally threaded onto the nozzle mounting block. Here, the support arm, two support arm mounting seats, nozzle mounting seats, and nozzles form a group, with a total of nine groups arranged in a circumferentially and evenly spaced pattern on the protective sleeve, allowing for comprehensive chemical etching of the deck and cooling of the friction disc.

[0010] Preferably, the top end of the support arm is rotatably connected to the support arm mounting seat on the support arm mounting ring via a rotating pin, and the bottom end of the support arm is rotatably connected to the support arm mounting seat on the nozzle mounting block via a rotating pin. The spraying mechanism is rotatably connected to the lifting mounting ring. Here, rotating pins are used to connect all nine sets of support arms and support arm mounting seats, which facilitates the disassembly, assembly, and routine maintenance of the spraying mechanism.

[0011] Preferably, the nozzle mounting block has rotating connecting columns fixed on both sides. These rotating connecting columns are connected to a protective sleeve. The protective sleeve includes a protective block, and a protective mounting block is mounted on the protective block. The protective mounting block is fixed to the protective block by fixing bolts. A rotating column mounting hole is provided on the side of the protective mounting block, and the rotating connecting column is rotatably connected to the protective mounting block through these holes. Here, two fixing bolts are provided, symmetrically arranged on the upper and lower sides of the protective mounting block, facilitating the disassembly and assembly of the nozzle mounting block and routine maintenance, thus enhancing the practicality of the equipment.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, by setting up a spraying mechanism, the lifting and lowering of the mounting ring is used, and the support arm is rotated by the support arm mounting ring. Under the limit of the protective mounting block, the angle of the nozzle mounting block is adjusted. When the protective sleeve rises, the nozzle tilts downward and sprays rust-removing liquid onto the deck. When the protective sleeve falls, the nozzle tilts upward and cools the friction disc. This allows the rust removal mechanism to obtain external cooling when working, improving the service life of the friction disc. Before rust removal, the rust stains on the deck are corroded, improving the rust removal efficiency of the device.

[0014] 2. In this utility model, a driving gear is set to drive the lifting gear ring to rotate. The lifting gear ring moves upward along the thread on the support column, and then the lifting gear ring drives the protective sleeve to rise. The upward or downward movement of the lifting gear ring also drives the upward or downward movement of the lifting mounting ring above it. This realizes the protection of the camera device by the protective sleeve when the friction disc is working, and also drives the angle change of the spray mechanism. The instantaneous locking of the equipment is realized by starting and stopping the motor, making the device more practical. Attached Figure Description

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1

[0025] Please see Figure 1-3This utility model provides a technical solution: a marine deck rust removal mechanism, including a rust removal component 3. The rust removal component 3 includes a support column 31, a locking drive mechanism 32 above the support column 31, a lifting mounting ring 33 rotatably connected below the support column 31, a spraying mechanism 34 rotatably connected to the lifting mounting ring 33, a lifting gear ring 35 threadedly connected below the support column 31, a connecting ring 36 at the bottom of the lifting gear ring 35, a protective sleeve 37 fixed at the bottom of the connecting ring 36, a mounting plate 38 fixed at the bottom of the support column 31, a friction plate 39 at the bottom of the mounting plate 38, the rust removal component 3 fixed to the bottom of the rust removal machine body 2, wheels 4 at the four corners of the bottom of the rust removal machine body 2, a camera device 1 fixed to the top of the rust removal machine body 2, and a locking drive mechanism 32. 2 includes an upper mounting plate 322, with a motor shaft 326 shaft 324 support sleeve 323 fixed to the bottom of the upper mounting plate 322. The motor shaft 326 shaft 324 is slidably connected below the motor shaft 326 shaft 324 support sleeve 323. The motor shaft 326 shaft 324 is fixedly connected to a drive gear 325, which is rotatably connected to the lower motor 326. The upper mounting plate 322 is mounted on the support column 31 via a positioning pin 321. The motor 326 is fixedly mounted on the protective sleeve 37. By setting a spray mechanism 34, the rising and falling of the lifting mounting ring 33, and the rotation of the support arm 343 driven by the mounting ring 341, and under the limit of the protective mounting block 372, the angle of the nozzle 345 mounting block 346 is adjusted. When the protective sleeve 372... When the protective sleeve 37 rises, the nozzle 345 tilts downwards to spray rust-removing liquid onto the deck. When the protective sleeve 37 descends, the nozzle 345 tilts upwards to cool the friction disc 39, ensuring external cooling during operation and extending the service life of the friction disc 39. Before rust removal, the rust stains on the deck are impregnated, improving the rust removal efficiency of the device. The rust-removing component 3 is the core of the entire rust-removing mechanism, responsible for performing the rust removal operation. The support column 31 provides structural support and connects components such as the upper locking drive mechanism 32 and the lower lifting mounting ring 33. The locking drive mechanism 32 is driven by a motor 326 to control the lifting and locking position of the rust-removing component 3, ensuring stability and accuracy during the rust removal process. The rust-removing machine body 2 serves as the carrier of the rust-removing component 3, providing... The mounting platform and wheels 4 enable the rust removal mechanism to move, facilitating rust removal operations in different locations. The camera device 1 monitors the rust removal process, providing real-time image feedback to help operators better control the progress and quality of the operation. The mounting plate 322 on the locking drive mechanism 32 serves as the mounting base for the motor 326 shaft 324 support sleeve 323 and the motor 326 shaft 324. The motor 326 shaft 324 support sleeve 323 supports the motor 326 shaft 324, ensuring its stable rotation. The motor 326 shaft 324 connects the drive gear 325 and the motor 326 to transmit power. The drive gear 325 cooperates with the lifting gear ring 35, and the lifting function is achieved through the motor 326. The motor 326 provides the power source to drive the entire locking drive mechanism 32 to work.

[0026] Example 2

[0027] Please see Figure 1-4The spray mechanism 34 includes a support arm 343 mounting ring 341, a support arm 343 mounting seat 342 fixed on the support arm 343 mounting ring 341, a support arm 343 connected to the support arm 343 mounting seat 342, a nozzle 345 mounting block 346 provided at the bottom of the support arm 343, a nozzle 345 mounting block 346 fixed at the top of the nozzle 343 mounting seat 342, the support arm 343 connected to the nozzle 345 mounting block 346 via the support arm 343 mounting seat 342, a nozzle 345 internally threaded onto the nozzle 345 mounting block 346, the top end of the support arm 343 rotatably connected to the support arm 343 mounting seat 342 on the support arm 343 mounting ring 341 via a rotating pin 344, and the bottom end of the support arm 343 connected to the nozzle 345 mounting block 346 via the rotating pin 344. 45 Mounting block 346 is rotatably connected to support arm 343 and mounting base 342. Spray mechanism 34 is rotatably connected to lifting mounting ring 33. Spray head 345 Mounting block 346 has rotating connecting columns 347 fixed on both sides. The rotating connecting columns 347 are connected to protective sleeve 37. Protective sleeve 37 includes protective block 371. Protective mounting block 372 is provided on protective block 371. Protective mounting block 372 is fixedly installed on protective block 371 by fixing bolt 373. Rotating column mounting hole 374 is provided on the side of protective mounting block 372. Rotating connecting column 347 is rotatably connected to protective mounting block 372 through rotating column mounting hole 374. The lifting gear ring 35 is driven to rotate by driving gear 325. The lifting gear ring 35 moves upward along the thread on support column 31 and then by The lifting gear ring 35 drives the protective sleeve 37 to rise. The upward or downward movement of the lifting gear ring 35 also drives the upward and downward movement of the lifting mounting ring 33 above it. This achieves the protection of the camera device 1 by the protective sleeve 37 when the friction disc 39 is working, and also drives the angle change of the spray mechanism 34. The instantaneous locking of the equipment is achieved by starting and stopping the motor 326, making the device more practical. The lifting mounting ring 33 connects the support column 31 and the spray mechanism 34, allowing the spray mechanism 34 to rotate up and down within a certain range to adapt to different rust removal needs. The spray mechanism 34 is responsible for spraying rust remover or water mist to soften the rust on the deck surface for easy subsequent removal. The support arm 343 mounting ring 341, support arm 343 mounting seat 342, and support arm 343 constitute the support of the spray mechanism 34. The structure allows the nozzle 345 to be flexibly adjusted within a certain range. The nozzle 345 mounting block 346 and the actual rust remover spraying component of the nozzle 345 are connected by threads for easy replacement of different models of nozzles 345. The rotating pin 344 allows the support arm 343 to rotate flexibly between the support arm 343 mounting base 342 and the nozzle 345 mounting block 346. The lifting gear ring 35 cooperates with the drive gear 325 to realize the lifting function of the rust removal component 3. The connecting ring 36 connects the lifting gear ring 35 and the protective sleeve 37, providing structural support. The protective sleeve 37 protects the motor 326 and other key components below the rust removal component 3 from damage, and also provides the installation position for the rotating connecting column 347. The mounting plate 38 fixes the support column 31 and the rust removal component 3, ensuring the stability of the overall structure.The friction disc 39 contacts the deck surface during the rust removal process, providing the necessary friction to help remove rust.

[0028] Working principle: When the rust removal mechanism starts working, the nozzle 345 operates, spraying rust removal liquid onto the deck. Then, the motor 326 starts running, driving the drive gear 325 to rotate. The drive gear 325 drives the lifting gear ring 35 to rotate. Because the lifting gear ring 35 has threads that mate with the support column 31, the lifting gear ring 35 will rise or fall along the support column 31. When the lifting gear ring 35 falls, it drives the connecting ring 36, which in turn drives the protective sleeve 37 to fall. After the lifting gear ring 35 falls, the lifting mounting ring 33, due to its weight... The force causes the lifting mounting ring 33 to descend, which in turn causes the support arm 343 mounting ring 341 to descend. This causes the support arm 343 to descend between the two support arm 343 mounting seats 342, which in turn causes the support arm 343 mounting seat 342 on the nozzle 345 mounting block 346 to move downward. At this time, the rotating connecting column 347 on the nozzle 345 mounting block 346 rotates around the rotating column mounting hole 374 on the protective mounting block 372, thereby driving the nozzle 345 to change direction and spray the rust removal liquid onto the friction disc 39 for cooling.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
