Description

Technical Field

[0001] This utility model relates to the field of ship maintenance technology, specifically to a rust removal device for ship maintenance. Background Technology

[0002] The deck, as a steel plate laid on the ship's beam, serves to reinforce the ship's structure and facilitate layered loading and cargo handling. Due to long-term exposure to seawater and other corrosive substances, it is prone to rusting, which affects its service life. Therefore, rust removal treatment is required to prevent further oxidation and corrosion.

[0003] The existing patent publication number CN219521786U discloses a rust removal device for ship deck maintenance. The first and second rotary motors control the support block to rotate in all directions, so that the high-pressure nozzle can automatically perform large-area sandblasting. There is no need for manual sandblasting by holding the high-pressure discharge pipe. While the high-pressure nozzle is sandblasting the deck to remove rust, two servo motors can be turned on at the same time to make the sanding wheel rotate quickly to polish the deck below, which improves work efficiency.

[0004] When the aforementioned patent is in use, the high-pressure nozzle is angled towards the deck to sandblast. After the sandblasting abrasive impacts the deck surface to remove rust, it splashes outward and scatters on the deck, making it inconvenient to clean and collect. It is also inconvenient to recycle and reuse the abrasive, which is a waste of resources. At the same time, its casters cannot be raised or lowered, and when it is not in use and is being pushed, the sanding wheel keeps rubbing against the deck surface, which is inconvenient to use. Utility Model Content

[0005] The purpose of this utility model is to provide a rust removal device for ship maintenance, in order to solve the problems mentioned in the background art, where sandblasting abrasives splash outwards and scatter on the deck after rust removal, making it inconvenient to clean and collect, and making it difficult to recycle and reuse the abrasives, resulting in a waste of resources; at the same time, its casters cannot be raised or lowered, and when not in use, the abrasive wheel keeps rubbing against the deck surface, making it inconvenient to use.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This utility model provides a technical solution: a rust removal device for ship maintenance, comprising a base plate 1, a slot 2 formed at the front of the top of the base plate 1, a crossbar 3 fixedly connected to the inner side of the slot 2, a sandblasting assembly 4 fixedly installed on the top of the base plate 1, a recovery assembly 5 fixedly installed on the bottom of the base plate 1, and a movable assembly 6 movably installed on the top of the base plate 1; the recovery assembly 5 includes a mounting frame 51 and two guide plates 52, the mounting frame 51 is fixedly installed on the rear side of the slot 2, the guide plates 52 are fixedly installed on the left and right sides of the slot 2, a rotating shaft 53 is rotatably installed on the inner side of the mounting frame 51, a brush 54 is fixedly installed on the bottom of the guide plates 52, and the outer side of the rotating shaft 53 is equidistantly fixed with a ring. The mounting bracket 51 is equipped with a second brush 55. A right-angle motor 56 connected to a rotating shaft 53 is fixedly installed on the side of the mounting bracket 51. A retaining rail 57 is fixedly installed at the rear of the bottom of the base plate 1. The collecting frame 58 located behind the rotating shaft 53 is movably engaged inside the retaining rail 57. When the base plate 1 is pushed, the first brush 54 sweeps and collects the sandblasting abrasive to the front of the second brush 55. The right-angle motor 56 drives the rotating shaft 53 inside the mounting bracket 51 to rotate. The second brush 55 sweeps the collected sandblasting abrasive into the collecting frame 58 for collection, preventing the sandblasting abrasive from scattering on the deck. After use, the collecting frame 58 can be slid out along the retaining rail 57 for disassembly, making it convenient to remove and process the collected sandblasting abrasive, achieving recycling and saving resources.

[0024] The two guide plates 52 are set in a "V" shape and tapered towards the second brush 55. The guide plates 52 can effectively guide the sandblasting abrasive to concentrate in the central area, reduce the material residue at the edge, and improve the guiding efficiency through the "V" shape tapering transition. This enhances the control of the sandblasting abrasive and ensures that it can be accurately collected into the working range of the second brush 55.

[0025] A rubber strip 59 is fixedly attached to the front of the collection frame 58. The rubber strip 59 can fit tightly against the inner wall of the rail 57 to form a good sealing effect, preventing the sandblasting abrasive from overflowing from the front of the collection frame 58 during the collection process. The elastic material of the rubber strip 59 prevents it from making rigid contact with the deck, thus avoiding scratches on the deck. In addition, the rubber strip 59 can also play a cushioning role, preventing the collection frame 58 from being damaged by collisions during movement.

[0026] An opening is provided at the rear of the base plate 1, and a rotating rod 510 is rotatably installed in the opening. The rotating rod 510 is locked to the rear side of the collection frame 58. The rotating rod 510 has movement damping. When it is in the vertical state, it can support and position the rear side of the collection frame 58 to prevent the collection frame 58 from sliding out of the rail 57. When the rotating rod 510 is rotated to the horizontal state, it releases the restriction on the collection frame 58, making it easy for the collection frame 58 to be pulled out of the rail 57, thus improving the convenience of operation.

[0027] A baffle 7 is fixedly installed at the bottom of the swing arm 44, covering the nozzle. The baffle 7 is made of wear-resistant material, which can effectively block the splashes generated during the sandblasting process, protect the surrounding environment and the safety of the operators, and at the same time prevent the sandblasting abrasive from splashing and scattering over a large area, making it easy to collect.

[0028] Please see Figure 5 The movable component 6 includes electric push rods 61 that are symmetrically fixedly installed on the top of the base plate 1. A support frame 62 is fixedly installed on the top of the electric push rods 61. Vertical rods 63 penetrating the base plate 1 are fixedly installed at the four corners of the bottom of the support frame 62. Casters 64 are fixedly installed at the bottom of each vertical rod 63. By controlling the synchronous extension and retraction of the electric push rods 61 on the left and right sides of the top of the base plate 1, the support frame 62 is raised and lowered by the electric push rods 61, thereby raising and lowering the vertical rods 63 inside the base plate 1. This adjusts the height between the base plate 1 and the deck, thereby preventing the components from always contacting the deck and causing wear under different usage conditions, and also facilitating movement.

[0029] Please see Figure 4 and Figure 5 The sandblasting assembly 4 includes a sealed tank 41 and a servo motor 43. The sealed tank 41 is fixedly installed at the rear of the top of the base plate 1. The servo motor 43 is fixedly installed at the top of the crossbar 3 and is centrally located. A sand pump 42 is fixedly installed on the top of the sealed tank 41. A swing arm 44 located below the crossbar 3 is fixedly installed on the outside of the output shaft of the servo motor 43. A sandblasting pipe 45 is fixedly connected to the top of the sand pump 42 and is clamped below the swing arm 44. A downward-facing nozzle is fixedly installed at the end of the sandblasting pipe 45 away from the sand pump 42. The sand pump 42 draws sandblasting abrasive from the sealed tank 41 and makes it enter the sandblasting pipe 45, and then sprays it out from the nozzle under high pressure to achieve rust removal. The servo motor 43 drives the swing arm 44 to swing back and forth, thereby expanding the rust removal range.

[0030] Working principle: By pushing the base plate 1 to the rust removal area, and controlling the electric push rods 61 on the left and right sides of the top of the base plate 1 to extend synchronously, the electric push rods 61 push the support frame 62 to move upward, thereby driving the vertical rod 63 to move upward along the inside of the base plate 1, adjusting the height between the base plate 1 and the deck, so that the rubber strip 59 contacts the deck surface, and the brush one 54 and brush two 55 adhere to the deck surface, so that the height can be adjusted when not in use, avoiding the friction of parts against the deck and facilitating movement;

[0031] The sand pump 42 draws sandblasting abrasive from the sealed tank 41 and enters the sandblasting pipe 45, from which it is sprayed out under high pressure from the nozzle to remove rust. The servo motor 43 can swing the swing arm 44 back and forth to expand the rust removal area. The base plate 1 is pushed to perform a comprehensive rust removal operation.

[0032] The abrasive particles are blocked by the baffle 7 and fall near the bottom of the base plate 1. By pushing the base plate 1, the brush 54 sweeps and collects the abrasive particles to the front of the brush 55. The right-angle motor 56 drives the rotating shaft 53 in the mounting bracket 51 to rotate, which in turn drives the brush 55 to rotate. The brush 55 sweeps the collected abrasive particles into the collection frame 58 for collection, preventing the abrasive particles from scattering on the deck and being inconvenient to collect. After use, the rotating rod 510 in the rear opening of the base plate 1 is rotated to release the limiting position of the collection frame 58. By pulling the collection frame 58 backward, the collection frame 58 slides backward along the rail 57 and is pulled out for disassembly, making it easy to take out the collected abrasive particles for processing, so as to recycle them and save resources. The above is the working process of the whole device. All contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
