Description

Technical Field

[0001] This utility model relates to the technical field of rust removal devices, specifically to a rapid rust removal device for shipbuilding decks. Background Technology

[0002] Deck rust removal is a crucial part of ship maintenance, aiming to remove rust, scale, and corrosion products to protect the deck structure and extend the ship's lifespan. Methods typically include manual grinding, mechanical sandblasting, or chemical rust removal, combined with high-pressure water cleaning to thoroughly remove the rust layer. Environmental protection is paramount during the process; waste residue and wastewater must be properly disposed of to prevent pollution. After rust removal, anti-rust primer and topcoat should be applied promptly to provide long-lasting protection. Regular maintenance improves ship safety and operational efficiency while reducing long-term maintenance costs.

[0003] Chinese patent CN110667798B discloses a ship deck rust removal device, including a working box and a working cavity located within the working box. A first fixing rod is fixed to the upper wall of the working cavity, and the first fixing rods are symmetrically arranged on both sides. A groove is fixed to the working box, and the groove is symmetrically arranged on both sides and located above the first fixing rod. The first fixing rod extends upward into the groove and is connected to the top wall of the groove via a first spring. A rust removal plate is fixed to the lower end face of the first fixing rod, and a rust removal blade is fixed to the lower end face of the rust removal plate. This rust removal device scrapes off all the rust on the deck. After completing the rust removal, the rust removal device is retracted, and a cleaning device is pushed out to sweep all the scraped rust to one place. A protective paint is automatically sprayed onto the cleaned portion of the deck, providing rust prevention treatment for the rust-removed deck.

[0004] The rust removal equipment described in the aforementioned patent document utilizes a fixed plate moving downwards to drive a second fixed rod downwards. The second fixed rod 37 then pushes out a cleaning plate, which, along with a cleaning brush, removes rust from the deck. However, when cleaning irregular deck surfaces of special engineering vessels (such as the giant grab buckets on dredgers, which require special supports and cause localized deck bulges), the rust removal equipment cannot completely remove the rust from the deck surface. Therefore, a rapid rust removal device for shipbuilding decks is proposed. Utility Model Content

[0005] To address the aforementioned problems, a rapid rust removal device for shipbuilding decks is provided. Multiple electrically operated telescopic rods work together to adjust an adjusting seat, allowing the edge of the adjusting seat to tilt around its central axis. Simultaneously, the adjusting seat also tilts the rust-removing brush. When a servo motor is activated, it rotates the rust-removing brush, enabling it to clean irregular deck surfaces. This solves the problem of rust removal devices being unable to clean irregular deck surfaces.

[0006] To address the existing technical problems, this application provides a rapid rust removal device for shipbuilding decks, comprising a cleaning mechanism installed at the bottom of a mobile trolley to clean rusted deck surfaces and a dust removal device installed on one side of the mobile trolley to remove impurities generated during cleaning. The bottom of the mobile trolley is provided with a clearance groove.

[0007] The cleaning mechanism includes a float that can move longitudinally. Multiple sets of individually adjustable electric telescopic rods are equidistantly arranged around the lower end face of the float around its central axis. The non-working ends of the electric telescopic rods are hinged to the lower end face of the float.

[0008] The cleaning mechanism also includes an adjustment seat, and the working end of the electric telescopic rod can be hinged to the top of the adjustment seat;

[0009] The bottom of the adjustment seat is rotatably equipped with a rust-removing brush for cleaning the deck surface.

[0010] As one technical solution of this application, the lower end face of the adjustment seat is fixed with an annular slide rail for limiting the position;

[0011] The upper surface of the rust removal brush is provided with an annular groove that can slide and engage with the annular slide rail.

[0012] As one technical solution of this application, the top of the mobile trolley is provided with a second installation chamber, and a hydraulic telescopic component capable of driving the float to move longitudinally is fixed at the center of the bottom of the second installation chamber. The float is fixedly connected to the output end of the hydraulic telescopic component.

[0013] As one technical solution of this application, the bottom of the second installation chamber is provided with a plurality of limiting holes for limiting the position, which are equidistant from the central axis of the hydraulic telescopic component.

[0014] The upper end face of the float plate is longitudinally mounted with a number of sliding rods corresponding to the limiting holes around its central axis, and the sliding rods slide in conjunction with the limiting holes.

[0015] As one technical solution of this application, the mobile vehicle also has a first installation chamber inside;

[0016] The dust removal device includes a dust collection box fixed inside a first installation chamber for storing impurities. An installation hole is provided on one side of the dust collection box, and an exhaust mechanism capable of drawing out the air inside the installation hole is installed inside the installation hole.

[0017] As one technical solution of this application, the dust removal device further includes a hood fixed to the bottom of the mobile trolley, the top of the hood being fixed to the side of the dust collection box, and the top of the hood being able to communicate with the inside of the dust collection box.

[0018] As one technical solution of this application, the exhaust mechanism includes a housing fixed inside the mounting hole, and a fan capable of drawing air out of the dust collection box is provided inside the housing.

[0019] An air filter element for filtering air is installed inside the input end of the housing.

[0020] As one technical solution of this application, an annular limiting seat for limiting the air filter element is fixed on the inner wall of the housing near the input end;

[0021] The inlet end of the housing is fixed with a retaining ring to prevent the air filter from falling off.

[0022] The advantages of this utility model compared to the prior art are:

[0023] This application utilizes multiple electrically operated telescopic rods working in concert to adjust the adjusting seat, allowing the edge of the adjusting seat to tilt around its central axis. Simultaneously, the adjusting seat also tilts the rust-removing brush. When the servo motor is activated, it rotates the rust-removing brush, enabling it to clean irregular deck surfaces. This solves the problem of rust removal devices being unable to clean irregular deck surfaces. Attached Figure Description

[0033] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0034] See Figures 1-8 As shown, a rapid rust removal device for shipbuilding decks includes a cleaning mechanism 2 installed at the bottom of a mobile trolley 1 to clean the rusted deck surface, and a dust removal device 3 installed on one side of the mobile trolley 1 to clean the impurities generated during cleaning. The bottom of the mobile trolley 1 is provided with a clearance groove 13.

[0035] The cleaning mechanism 2 includes a float 21 that can move longitudinally. Multiple sets of individually adjustable electric telescopic rods 22 are equidistantly arranged around its central axis on the lower end face of the float 21. The non-working ends of the electric telescopic rods 22 are hinged to the lower end face of the float 21.

[0036] The cleaning mechanism 2 also includes an adjustment seat 23, and the working end of the electric telescopic rod 22 can be hinged to the top of the adjustment seat 23;

[0037] The bottom of the adjustment seat 23 is rotatably equipped with a rust-removing brush 25 for cleaning the deck surface.

[0038] A servo motor 24, capable of driving the rust-removing brush 25 to rotate, is fixed at the center of the upper surface of the adjusting seat 23. The rust-removing brush 25 is fixedly connected to the servo motor 24. When the rust-removing brush 25 cleans the irregular deck surface, multiple electric telescopic rods 22 work together to adjust the adjusting seat 23, allowing the edge of the adjusting seat 23 to tilt around its central axis. Simultaneously, the adjusting seat 23 can synchronously adjust the tilt of the rust-removing brush 25. When the servo motor 24 is started, it drives the rust-removing brush 25 to rotate, enabling the rust-removing brush 25 to clean the irregular deck surface.

[0039] See Figure 5 and Figure 6As shown, an annular slide rail 231 for limiting is fixed on the lower end face of the adjusting seat 23;

[0040] The upper end face of the rust removal brush 25 is provided with an annular groove 251 that can slide and engage with the annular slide rail 231.

[0041] To ensure stable operation of the rust-removing brush 25, an annular slide rail 231 is provided on the lower end face of the adjusting seat 23, and an annular groove 251 is formed on the upper end face of the rust-removing brush 25, allowing the annular groove 251 to slide in conjunction with the annular slide rail 231. When the rust-removing brush 25 rotates, it can move along the annular slide rail 231 through the annular groove 251. This effectively ensures the stable operation of the rust-removing brush 25.

[0042] See Figure 3 , Figure 5 and Figure 6 As shown, a second installation chamber 12 is provided at the top of the mobile trolley 1. A hydraulic telescopic component 4, which can drive the float 21 to move longitudinally, is fixed at the center of the bottom of the second installation chamber 12. The float 21 is fixedly connected to the output end of the hydraulic telescopic component 4.

[0043] By fixing the float plate 21 to the output end of the hydraulic telescopic component 4, the hydraulic telescopic component 4 can drive the float plate 21 to move longitudinally. At the same time, the float plate 21 drives the adjusting seat 23 and the rust removal brush 25 to move downward synchronously through the electric telescopic rod 22 hinged to its lower end face, thereby allowing the height of the rust removal brush 25 to be adjusted.

[0044] See Figure 4 , Figure 5 and Figure 6 As shown, the bottom of the second installation chamber 12 is provided with a number of limiting holes 121 for limiting the position, which are equidistant from the central axis of the hydraulic telescopic component 4.

[0045] The upper end face of the float plate 21 is longitudinally mounted with a number of slide rods 211 corresponding to the limiting holes 121 around its central axis, and the slide rods 211 slide in cooperation with the limiting holes 121.

[0046] To ensure the stability of the float plate 21, several sliding rods 211 are fixed to the upper surface of the float plate 21, and then the sliding rods 211 are inserted into the limiting holes 121. When the float plate 21 moves longitudinally, it can synchronously drive the sliding rods 211 to move longitudinally. At this time, the sliding rods 211 will move in the direction of the central axis of the limiting holes 121. This restricts the movement position of the sliding rods 211 by the limiting holes 121, preventing the float plate 21 from deviating during movement. This effectively ensures the stability of the float plate 21.

[0047] See Figure 3 , Figure 6 and Figure 7 As shown, the mobile trolley 1 also has a first installation chamber 11 inside;

[0048] The dust removal device 3 includes a dust collection box 31 fixed inside the first installation chamber 11 for storing impurities. A mounting hole 32 is provided on one side of the dust collection box 31, and an exhaust mechanism 33 capable of extracting air from the inside of the mounting hole 32 is installed inside the mounting hole 32.

[0049] A dust collection box 31 is installed inside the first installation chamber 11 to store impurities. An installation hole 32 is provided on one side of the dust collection box 31, and an exhaust mechanism 33 is installed inside the installation hole 32, so that the input end of the exhaust mechanism 33 is inside the dust collection box 31. This allows the exhaust mechanism 33 to draw air out of the dust collection box 31, creating a negative pressure environment inside the dust collection box 31.

[0050] See Figure 3 and Figure 6 As shown, the dust removal device 3 also includes a hood 34 fixed to the bottom of the mobile trolley 1. The top of the hood 34 is fixed to the side of the dust collection box 31, and the top of the hood 34 can communicate with the inside of the dust collection box 31.

[0051] By fixing the hood 34 to the bottom of the moving trolley 1 and then fixing the top of the hood 34 to the side of the dust collection box 31, the hood 34 can communicate with the inside of the dust collection box 31. When the inside of the dust collection box 31 is under negative pressure, external air will enter from the input end of the hood 34 and then enter the inside of the dust collection box 31 from the top of the hood 34. During this process, the air will carry the impurities generated during the cleaning of the rust removal brush 25 into the dust collection box 31 for storage.

[0052] See Figure 7 As shown, the exhaust mechanism 33 includes a housing 331 fixed inside the mounting hole 32, and a fan 332 is provided inside the housing 331 to draw air out of the dust collection box 31.

[0053] An air filter element 334 for filtering air is installed inside the inlet of housing 331.

[0054] By fixing the fan 332 inside the housing 331, the fan 332 can effectively exhaust the air inside the housing 331 when it is started. During the process of the fan 332 driving the air out of the housing 331, the air filter element 334 can filter the air, effectively removing impurities carried in the air and preventing the exhaust air from polluting the environment.

[0055] See Figure 7 As shown, an annular limiting seat 333 for limiting the air filter element 334 is fixed on the inner wall of the housing 331 near the input end.

[0056] The input end of housing 331 is fixed with a retaining ring 335 to prevent air filter 334 from falling off.

[0057] To ensure the stability of the air filter element 334, an annular limiting seat 333 is fixed to the inner wall of the output end of the housing 331. When the air filter element 334 is installed inside the housing 331, the annular limiting seat 333 effectively prevents the air filter element 334 from getting too close to the fan 332, avoiding collision between the fan 332 and the air filter element 334. Then, a retaining ring 335 is fixed to the input end of the housing 331, so that the retaining ring 335 cooperates with the annular limiting seat 333 to fix the air filter element 334, effectively preventing the air filter element 334 from falling out of the housing 331.

[0058] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
