Description

Technical Field

[0001] This utility model relates to the field of painting equipment technology, specifically to a painting equipment for ship parts. Background Technology

[0002] In the field of shipbuilding and maintenance, the painting of ship parts is a crucial process. Ships operate in a complex and harsh marine environment, and the surfaces of their parts are susceptible to various factors such as seawater corrosion, marine organism adhesion, and the impact of wind and waves. Painting ship parts not only significantly improves their appearance but, more importantly, forms an effective protective layer on their surface, enhancing their corrosion resistance and wear resistance. This extends the service life of the ship parts and ensures the safe and stable operation of the vessel.

[0003] Most spray painting equipment has inconvenient spraying angle adjustment of the nozzles, making it difficult to achieve all-round uniform spraying of ship parts. This results in some parts of the ship parts not being adequately covered by the paint layer, thus forming paint dead spots. Once these paint dead spots are exposed to the marine environment, they are very prone to corrosion, which in turn affects the overall performance and service life of the ship parts.

[0025] A connecting pipe 39 is fixedly connected to the outer wall of the nozzle 310. Limiting discs 37 are fixedly connected to the outer walls of both sides of the rotating rod 36. Inserted posts 38 are inserted into the inner walls of the limiting discs 37.

The bottom of the nozzle 310 is fixedly connected to the inner wall of the bottom of the fixed shell 35. The inner wall at the center of the liquid storage shell 1 is rotatably connected to the outer wall of the rotating shaft 32. When it is necessary to adjust the spraying angle of the nozzle 310, the operator presses the two sets of inserts 38 so that the inserts 38 slide into the fixed rod 34.

Under the action of the top spring 311, the inserts 38 are reinserted into the corresponding holes of the limiting plate 37, thereby fixing the angle of the rotating rod 36 and realizing the adjustment of the spraying angle of the nozzle 310.

[0026] The recycling component 2 includes a baffle 21, with a connecting ring 22 fixedly connected to the bottom of the baffle 21. The bottom of the connecting ring 22 is rotatably connected to a limiting shell 23 via a slider 24, and the outer wall of the slider 24 is slidably connected to the inner wall of the limiting shell 23. A connecting frame 25 is fixedly connected to the outer wall of the connecting ring 22. The bottom of the limiting shell 23 is fixedly connected to the top of the liquid storage shell 1. The outer wall at the center of the connecting frame 25 is fixedly connected to the outer wall of the rotating shaft 32. The top of the slider 24 is fixedly connected to the bottom of the connecting ring 22. Excess paint splashed will come into contact with the rotating baffle 21. Due to the obstruction of the baffle 21, the paint flows down along the baffle 21, and flows back into the liquid storage shell 1 through the connecting ring 22 and the limiting shell 23. A through groove is provided at the top of the liquid storage shell 1, so that the recycled paint flows back into the liquid storage shell 1 through the through groove.

[0027] The ship parts painting equipment mainly consists of a liquid storage tank 1, a recovery component 2, and a spray component 3. The liquid storage tank 1 serves as the basic component and is used to store the paint required for the painting operation. The recovery component 2 is fixed to the top of the liquid storage tank 1 and its function is to collect excess paint splashed during the painting process. The spray component 3 is installed on the inner wall of the liquid storage tank 1 and is responsible for painting the ship parts. Before using the painting equipment to paint the ship parts, the ship parts need to be hoisted between the spray components 3 to facilitate the painting work of the spray components 3.

[0028] The spray assembly 3 is mainly composed of a stepper motor 31, a rotating shaft 32, a fixed rod 34, a rotating rod 36, a fixed shell 35, a water pump 33, and a spray head 310. The stepper motor 31 serves as a power source, and its output shaft drives the rotating shaft 32 at the top to rotate. The rotating shaft 32 is a key component for power transmission, which transmits the rotational motion of the stepper motor 31 to the fixed rod 34.

[0029] The fixed rods 34 are arranged in a circular array along the central axis of the rotating shaft 32 and are fixedly connected to the outer wall of the rotating shaft 32. As the rotating shaft 32 rotates, the fixed rods 34 move in a circular motion around the rotating shaft 32. A rotating rod 36 is rotatably connected to the top of the fixed rods 34. The rotating rod 36 can rotate within a certain range around its connection point with the fixed rod 34. Limiting disks 37 are fixedly connected to the outer walls on both sides of the rotating rod 36. Inserted posts 38 are inserted into the inner walls of the limiting disks 37. Tops are fixedly connected to the outer walls of the inserted posts 38. Spring 311, the end of top spring 311 away from the insert post 38 is fixedly connected to the inner wall of fixed rod 34. When it is necessary to adjust the spraying angle of nozzle 310, the operator presses the two sets of insert posts 38, so that the insert posts 38 slide into fixed rod 34, and then applies external force to rotate rod 36. After rotating to the appropriate angle, the external force is removed, and the insert posts 38 are reinserted into the corresponding holes of limit plate 37 under the action of top spring 311, thereby fixing the angle of rotating rod 36 and realizing the adjustment of spraying angle of nozzle 310.

[0030] The fixed housing 35 is rotatably connected to the inner wall of the rotating shaft 32, and its outer wall is connected to the water pump 33 through a pipe. The water pump 33 is fixed to the inner wall of the bottom of the liquid storage shell 1. According to the working principle of a centrifugal pump, when the water pump 33 is working, under the action of centrifugal force generated by the high-speed rotation of the internal impeller, the paint liquid in the liquid storage shell 1 is drawn into the pump body and transported to the fixed housing 35 through the pipe. A slot is opened between the rotating shaft 32 and the fixed housing 35, so that the paint liquid enters the rotating shaft 32 through the slot and flows to the fixed housing 35 under the push of the subsequent paint liquid. At the fixed rod 34, a slot is also provided between the fixed rod 34 and the rotating shaft 32. Thus, the paint can enter the connecting pipe 39 from the rotating shaft 32 through the slot. The paint is then transported to the nozzle 310 on the inner wall of the fixed rod 34 through the connecting pipe 39. The nozzle 310 uses the principle of fluid dynamics to spray the paint with a certain pressure and atomization effect, thereby realizing the painting operation of the ship parts. Since the fixed rod 34 rotates with the rotating shaft 32, the nozzle 310 also makes a circular motion, thereby realizing the all-round painting of the ship parts.

[0031] The recycling assembly 2 consists of components such as a baffle 21, a connecting ring 22, a slider 24, and a limiting shell 23. The bottom of the baffle 21 is fixedly connected to the connecting ring 22. The bottom of the connecting ring 22 is rotatably connected to the limiting shell 23 through the slider 24, and the outer wall of the slider 24 slides with the inner wall of the limiting shell 23. The outer wall of the connecting ring 22 is fixedly connected to the connecting frame 25. The outer wall at the center of the connecting frame 25 is fixedly connected to the outer wall of the rotating shaft 32. Therefore, when the rotating shaft 32 rotates, the connecting ring 22 is driven to rotate through the connecting frame 25, thereby causing the baffle 21 to rotate together with the rotating shaft 32.

[0032] During the painting process, based on the principle of inertia, the splashed excess paint will come into contact with the rotating baffle 21. Due to the obstruction of the baffle 21, the paint flows down the baffle 21 and flows back into the liquid storage tank 1 through the connecting ring 22 and the limiting shell 23. This recycling method realizes the recycling and reuse of paint, improves the utilization rate of paint, and reduces the pollution of paint to the working environment.
