Description

Technical Field

[0001] This utility model belongs to the technical field of sandblasting equipment, and particularly relates to a sandblasting equipment for ship mid-plate. Background Technology

[0002] Midships plating is a type of ship plate used to manufacture ship hull structures. It has high tensile and yield strength, enabling it to withstand various external forces encountered by the ship during navigation, such as the impact of waves and the weight of cargo, ensuring the stability and safety of the hull structure. It also maintains good toughness in low-temperature environments and is not prone to brittle fracture, which is especially important for ships navigating in cold waters. With special anti-corrosion treatment or by means of corrosion-resistant alloy components, it can be used for a long time in high-humidity, high-salinity marine environments without being easily corroded, thus extending the service life of the ship.

[0003] During the production process, the surface of the ship's midplate is prone to residual oil, grease and other impurities. When the midplate is directly sandblasted, these impurities can cause the abrasive particles to stick together when impacting the surface, reducing the impact force and rebound speed of the abrasive. This prevents the abrasive from effectively cleaning and roughening the steel plate surface, increasing the number of sandblasting passes and operation time, and reducing efficiency. Utility Model Content

[0004] To address the aforementioned problems, this invention proposes a sandblasting device for ship midsection plates, which more accurately solves the problems described above.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model proposes a sandblasting treatment device for ship midships, including a conveyor belt, a sandblasting machine installed on the conveyor belt, a support plate fixedly connected to one side of the conveyor belt, a support base fixedly connected to the lower surface of the support plate, and a cleaning component provided on the upper surface of the support plate for cleaning the ship midships.

[0007] In one example, the cleaning assembly includes a fixed box fixedly connected to a support plate. The fixed box has open sides. Two first rotating rollers and two second rotating rollers are rotatably connected to the side walls of the fixed box. A first threaded rod is threadedly connected to the upper surface of the fixed box, penetrating the fixed box. The lower end of the first threaded rod is rotatably connected to a mounting frame located inside the fixed box. The side wall of the mounting frame contacts the side wall of the fixed box. Two third rotating rollers and two fourth rotating rollers are rotatably connected to the inner wall of the mounting frame. Wiping belts are fitted on the outer sides of the two first rotating rollers and the three rotating rollers. Cleaning belts are fitted on the outer sides of the two second rotating rollers and the four rotating rollers. The cleaning belts are close to the conveyor belt.

[0008] In one example, two first servo motors are fixedly connected to one side of the fixed box, and the main shafts of the two first servo motors are respectively fixedly connected to one first rotating roller and one second rotating roller. Two second servo motors are fixedly connected to the outside of the mounting bracket, and the main shafts of the two second servo motors are respectively fixedly connected to one third rotating roller and one fourth rotating roller. A square through groove is provided on one side of the fixed box.

[0009] In one example, a fixing frame is fixedly connected to one side of the fixing box, a mounting plate is fixedly connected to one side of the fixing frame, a cylinder is fixedly connected to the upper surface of the mounting plate, and a push rod is fixedly connected to the telescopic rod of the cylinder.

[0010] In one example, two sliding rods are slidably connected to the side wall of the fixed frame, a support plate is fixedly connected to the opposite side of the sliding rods, and a push block is fixedly connected to the opposite side of the two support plates.

[0011] In one example, the side walls on both sides of the fixing frame are threadedly connected to a second threaded rod, which passes through the fixing frame and is rotatably connected to the support plate.

[0012] In one example, the upper surface of the fixture is aligned with the upper surfaces of the wiping and cleaning belts inside the fixture box, and the upper surfaces of the wiping and cleaning belts are higher than the upper surface of the conveyor belt.

[0013] The sandblasting equipment for ship mid-plate proposed in this utility model can bring the following beneficial effects:

[0014] Firstly, by setting up wiping and cleaning belts, the board enters the fixed box and passes through the corresponding wiping and cleaning belts. The wiping belts wipe the upper and lower surfaces of the board to remove oil stains. Then, the board comes into contact with the corresponding cleaning belts, which remove dust and other dirt from the board, improving the cleanliness of the board and preventing stains from obstructing the abrasive and reducing its impact. At the same time, the device can process shipboard plates of different thicknesses.

[0015] Secondly, by setting a push plate, the second threaded rod pushes the push blocks closer to each other, so that the distance between the two push blocks is the same as the width of the plate. When the plate is placed on the fixed frame, under the limiting action of the two push blocks, the plate is located in the middle of the fixed frame and will not shift, avoiding the plate from tilting when the push rod pushes the plate. The device can adapt to the midship plate of different widths, increasing the range of applications of the device. Attached Figure Description

[0023] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0024] like Figures 1-4 As shown in the figure, an embodiment of this utility model proposes a sandblasting device for ship midship plates. The device includes a conveyor belt 1, on which a sandblasting machine 2 is mounted. A support plate 3 is fixedly connected to one side of the conveyor belt 1, and a support seat 4 is fixedly connected to the lower surface of the support plate 3. A cleaning component 5 is provided on the upper surface of the support plate 3. The cleaning component 5 is used to clean the ship midship plate. The midship plate first passes through the cleaning component 5 on one side to clean residual oil stains and other dirt from the surface. After cleaning, the midship plate falls onto the conveyor belt 1, which transports the cleaned midship plate to the sandblasting machine 2. As it passes through the sandblasting machine 2, sandblasting is performed to prevent residual oil stains on the midship plate from reducing the impact and cutting effect of the abrasive on surface impurities, thus affecting the cleaning effect.

[0025] like Figure 2 and Figure 3As shown, the cleaning component 5 includes a fixed box 51, which is fixedly connected to the support plate 3. The fixed box 51 has open sides. Two first rotating rollers 52 and two second rotating rollers 53 are rotatably connected to the side walls of the fixed box 51. A first threaded rod 54 is threaded onto the upper surface of the fixed box 51, penetrating the fixed box 51. The lower end of the first threaded rod 54 is rotatably connected to a mounting frame 55, which is located inside the fixed box 51. The side wall of the mounting frame 55 contacts the side wall of the fixed box 51. Two third rotating rollers 56 and two fourth rotating rollers 57 are rotatably connected to the inner wall of the mounting frame 55. Wiping strips 58 are fitted onto the outer sides of the two first rotating rollers 52 and the third rotating rollers 56, and cleaning strips 59 are fitted onto the outer sides of the two second rotating rollers 53 and the fourth rotating rollers 57. When cleaning, the first threaded rod 54 is rotated near the conveyor belt 1. The first threaded rod 54 pushes the mounting frame 55 downward, and the mounting frame 55 descends in the fixed box 51, approaching the first rotating roller 52 and the second rotating roller 53 below. This brings the corresponding wiping belt 58 and cleaning belt 59 closer together. The midship plate is placed on one side of the fixed box 51, and the plate is pushed into the fixed box 51, allowing the plate to pass through the corresponding wiping belt 58 and cleaning belt 59. The wiping belt 58 wipes the upper and lower surfaces of the plate, removing oil stains. Then, the plate contacts the corresponding cleaning belt 59, which cleans dust and other dirt from the plate, improving its cleanliness and preventing stains from obscuring the abrasive, thus reducing its impact on the abrasive. At the same time, the device can process midship plates of different thicknesses.

[0026] like Figure 2 and Figure 3 As shown, two first servo motors 6 are fixedly connected to one side of the fixed box 51. The main shafts of the two first servo motors 6 are respectively fixedly connected to one of the first rotating rollers 52 and one of the second rotating rollers 53. Two second servo motors 7 are fixedly connected to the outside of the mounting bracket 55. The main shafts of the two second servo motors 7 are respectively fixedly connected to one of the third rotating rollers 56 and one of the fourth rotating rollers 57. A square through groove is provided on one side of the fixed box 51. When in use, the first servo motors 6 and the second servo motors 7 are started, driving the cleaning belt 59 and the wiping belt 58 to rotate. When the ship's midship plate passes through the fixed box 51, the rotating cleaning belt 59 and the wiping belt 58 clean and wipe the plate. The rotation direction of the cleaning belt 59 and the wiping belt 58 is opposite to the forward direction of the plate, which greatly improves the cleaning effect on the plate.

[0027] like Figure 2 and Figure 3As shown, a fixed frame 8 is fixedly connected to one side of the fixed box 51, and a mounting plate 9 is fixedly connected to one side of the fixed frame 8. A cylinder 10 is fixedly connected to the upper surface of the mounting plate 9, and a push rod 11 is fixedly connected to the telescopic rod of the cylinder 10. The plate is placed on the fixed frame 8, and the side of the plate is pushed by the cylinder 10 and the push rod 11, which pushes the plate to move through the fixed box 51 for cleaning and wiping.

[0028] like Figure 2 , Figure 3 as well as Figure 4 As shown, two sliding rods 12 are slidably connected to the side wall of the fixed frame 8. A support plate 13 is fixedly connected to the opposite side of the sliding rods 12, and a push block 14 is fixedly connected to the opposite side of the two support plates 13. The side walls on both sides of the fixed frame 8 are threaded with second threaded rods 15, which pass through the fixed frame 8 and are rotatably connected to the support plates 13. In use, the second threaded rods 15 on both sides are rotated to push the push blocks 14 closer to each other, so that the distance between the two push blocks 14 is the same as the width of the plate. When the plate is placed on the fixed frame 8, the plate is positioned in the middle of the fixed frame 8 under the limiting action of the two push blocks 14 and will not shift, thus preventing the plate from tilting when the push rod 11 pushes the plate. The device can adapt to the midship plate of different widths, increasing the range of applications of the device.

[0029] like Figure 1 As shown, the upper surface of the fixing frame 8 is aligned with the upper surfaces of the wiping belt 58 and the cleaning belt 59 inside the fixing box 51. The upper surfaces of the wiping belt 58 and the cleaning belt 59 are higher than the upper surface of the conveyor belt 1. When the board passes through the fixing box 51, the board is conveniently placed on the conveyor belt 1 for transportation because the conveyor belt 1 is lower.

[0030] Working principle: Rotating the second threaded rods 15 on both sides causes the second threaded rods 15 to push the push blocks 14 closer together, so that the distance between the two push blocks 14 is the same as the width of the plate. When the plate is placed on the fixed frame 8, under the limiting action of the two push blocks 14, the plate is positioned in the middle of the fixed frame 8. Rotating the first threaded rod 54 pushes the mounting frame 55 downward. The mounting frame 55 descends in the fixed box 51 and approaches the first rotating roller 52 and the second rotating roller 53 below, so that the corresponding wiping belt 58 and cleaning belt 59 are brought closer. The cylinder 10 and the push rod 11 push the side of the plate, pushing the plate to move through the fixed box 51. The first servo motor 6 and the second servo motor 7 start, driving the cleaning belt 59 and the wiping belt 58 to rotate. When the midship plate passes through the fixed box 51, the rotating cleaning belt 59 and the wiping belt 58 clean and wipe the plate.
