Description

Technical Field

[0001] This utility model relates to the technical field of cold spray anti-corrosion devices, specifically a cold spray anti-corrosion device for the antimagnetic hook of an aluminum electrolytic crane. Background Technology

[0002] In the high-temperature, highly corrosive, and strong magnetic field environment of aluminum electrolysis production, crane antimagnetic hooks must simultaneously meet the requirements of antimagnetism and corrosion resistance. Using non-magnetic materials such as aluminum alloys can avoid magnetic field interference, but traditional protection technologies have obvious shortcomings: paint coatings peel off after 1-3 months, anodizing treatment can only extend the life to 12-18 months, thermal spraying is prone to deformation of the aluminum alloy substrate due to high temperature and the coating has high porosity, while titanium alloys, although corrosion resistant, are expensive, thickening aluminum alloys will reduce lifting efficiency, and welding metal layers are prone to deformation and localized corrosion. As the industry develops towards larger sizes, the expected life of hooks is ≥24 months and the failure rate is ≤0.5% / year. Although cold spraying technology can prepare dense antimagnetic coatings at low temperatures.

[0003] In existing aluminum electrolysis crane antimagnetic hook cold spray anti-corrosion devices, the powder needs to be sprayed onto the hook surface through a spray gun at supersonic speed. Due to the complex structure of the hook, some powder leaves the airflow trajectory without impacting the substrate and scatters onto the workbench and surrounding areas. On the other hand, the workbench in aluminum electrolysis workshops is mostly an open design without effective enclosure structure, and the splashed powder easily spreads to the gaps in the workbench, the surface of surrounding equipment, and the ground, forming a large area of ​​scattering, which leads to powder waste and difficulty in cleaning. To address this, we propose an aluminum electrolysis crane antimagnetic hook cold spray anti-corrosion device. Utility Model Content

[0004] The purpose of this utility model is to provide a cold spray anti-corrosion device for the antimagnetic hook of an aluminum electrolysis crane, so as to solve the problems mentioned in the background art.

[0005] The objective of this utility model can be achieved through the following technical solutions: A cold-spray anti-corrosion device for the antimagnetic hook of an aluminum electrolysis crane includes: a body; a transmission mechanism is installed on the top of the body; a first motor is fixedly connected to the left side of the transmission mechanism; the output end of the first motor is fixedly connected to the input end of the transmission mechanism; a powder storage tank is installed on the transmission mechanism; a high-pressure spray gun is installed at the bottom of the powder storage tank; a clamping assembly is installed on the body below the high-pressure spray gun; and a protective assembly is slidably connected to the clamping assembly. The protective assembly includes a first protective housing and a second protective housing that are slidably connected to two clamping assemblies. The first protective housing and the second protective housing are slidably connected. A through hole is provided on the surface of the machine body below the first protective housing and the second protective housing. A funnel is fixedly connected to the outer wall of the machine body below the through hole. A collection tank is threadedly connected to the funnel. The high-pressure spray gun is slidably connected to the first protective housing and the second protective housing.

[0006] Preferably, the clamping assembly includes two sets of guide rails symmetrically fixedly connected to the machine body, with sliders slidably connected to the guide rails.

[0007] Preferably, a second gear is fixedly connected to one end of the clamping plate away from the fixing plate, and a sliding groove is provided inside the first protective shell and the second protective shell.

[0014] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0015] like Figures 1-4 As shown, a cold spray anti-corrosion device for the anti-magnetic hook of an aluminum electrolysis crane includes: a body 1, a transmission mechanism 2 mounted on the top of the body 1, a first motor 3 fixedly connected to the left side of the transmission mechanism 2, the output end of the first motor 3 fixedly connected to the input end of the transmission mechanism 2, a powder storage tank 4 mounted on the transmission mechanism 2, a high-pressure spray gun 5 mounted at the bottom of the powder storage tank 4, a clamping assembly 6 mounted on the body 1 below the high-pressure spray gun 5, and a protective assembly 7 slidably connected to the clamping assembly 6. The protective assembly 7 includes a first protective housing 71 and a second protective housing 72 that are slidably connected to two clamping assemblies 6 respectively. The first protective housing 71 and the second protective housing 72 are slidably connected. A through hole 76 is provided on the surface of the body 1 below the first protective housing 71 and the second protective housing 72. A funnel 77 is fixedly connected to the outer wall of the body 1 below the through hole 76. A collection tank 78 is threadedly connected to the funnel 77. The high-pressure spray gun 5 is slidably connected to the first protective housing 71 and the second protective housing 72.

[0016] In specific implementation, a first protective shell 71 and a second protective shell 72 are slidably connected to the clamping assembly 6. When the clamping assembly 6 clamps the hook, it drives the second protective shell 72 to move synchronously with the first protective shell 71, and causes the first protective shell 71 to slide into the second protective shell 72. This achieves the purpose of shielding the powder splashed during the cold spraying process, preventing the powder from falling onto the machine body 1, which is inconvenient to clean and also causes waste. At the same time, the shielded powder falls into the through hole 76 and then into the collection tank 78 through the funnel 77, thereby achieving the purpose of collecting some of the powder so that the staff can reuse the powder.

[0017] As a technical optimization of this utility model, the clamping assembly 6 includes two sets of guide rails 61 symmetrically fixedly connected to the body 1. Slider 62 is slidably connected to the guide rails 61. A first rack 63 is fixedly connected to one side of the two sliders 62. A second motor 64 is fixedly connected to the bottom of the body 1. A first gear 65 is fixedly connected to the output end of the second motor 64. Both first racks 63 mesh with the first gear 65. A first connecting plate 66 is fixedly connected to the top of one set of sliders 62. A second connecting plate 67 is fixedly connected to the top of the other set of sliders 62. Fixing plates 68 are fixedly connected to the rear surfaces of the first connecting plate 66 and the second connecting plate 67. Clamping plates 69 are rotatably connected inside the fixing plates 68. A first protective shell 71 and a second protective shell 72 are slidably connected to the two second connecting plates 67 respectively.

[0018] In specific implementation, by starting the second motor 64, the second motor 64 drives the first gear 65 to rotate. The first gear 65 synchronously drives the two sets of first racks 63, causing the two sets of first racks 63 to drive the two sets of sliders 62 to slide in opposite directions on the guide rail 61. The sliders 62 drive the two sets of fixed plates 68 to converge towards the center through the first connecting plate 66 and the second connecting plate 67, until the two sets of clamping plates 69 clamp the hook. Then, cold spraying is performed by the high-pressure spray gun 5. At the same time, when the first connecting plate 66 and the second connecting plate 67 move, they synchronously drive the first protective shell 71 and the second protective shell 72 to slide and connect, so that the first protective shell 71 and the second protective shell 72 form a shield to block the splashed powder.

[0019] As a technical optimization of this utility model, a second gear 73 is fixedly connected to one end of the clamping plate 69 away from the fixing plate 68. A sliding groove 74 is opened in the first protective shell 71 and the second protective shell 72. A second rack 75 is slidably connected in the sliding groove 74, and the second rack 75 meshes with the second gear 73.

[0020] In practice, by pulling the second rack 75, the second rack 75 slides upward in the slide groove 74, driving the second gear 73 to rotate. Then, the second gear 73 synchronously drives the clamping plate 69 to rotate, thereby achieving the purpose of adjusting the angle of the hook, so that the cold spray powder is evenly sprayed on the hook, thereby improving the spraying efficiency.

[0021] As a technical optimization of this utility model, anti-slip pads are provided on one side of each of the two clamping plates 69, and both clamping plates 69 are rectangular in shape.

[0022] In practice, this can prevent the clamping force of the two sets of clamping plates 69 from being too large, which could cause the coating on the hook surface to fall off or be damaged.

[0023] As a technical optimization of this utility model, both the first protective shell 71 and the second protective shell 72 are designed to be transparent, and the bottom of both the first protective shell 71 and the second protective shell 72 are attached to the surface of the body 1.

[0024] In practice, the first protective shell 71 and the second protective shell 72 can move synchronously with the first connecting plate 66 and the second connecting plate 67, so that the first protective shell 71 and the second protective shell 72 can scrape off the small amount of powder on the machine body 1, and let the powder fall into the through hole 76, thereby achieving the purpose of cleaning the powder on the surface of the machine body 1.

[0025] As a technical optimization of this utility model, the second rack 75 is designed in a C-shape, and an arc-shaped groove is provided in the middle of the second rack 75.

[0026] In practice, this allows staff to operate both sides of the second rack 75 simultaneously, and the force output to the second rack 75 is evenly distributed to both sides of the second rack 75, so that the second rack 75 slides stably within the two sets of sliding grooves 74.

[0027] In use, this utility model involves starting the second motor 64, which drives the first gear 65 to rotate. The first gear 65 simultaneously drives two sets of first racks 63, causing the two sets of first racks 63 to drive two sets of sliders 62 to slide in opposite directions on the guide rail 61. The sliders 62, through the first connecting plate 66 and the second connecting plate 67, drive the two sets of fixing plates 68 to converge towards the center until the two sets of clamping plates 69 clamp the hook. Then, a high-pressure spray gun 5 performs cold spraying. Simultaneously, as the first connecting plate 66 and the second connecting plate 67 move, they simultaneously drive the first protective shell 71 and the second protective shell 72 to slide together, thus connecting the first protective shell 71 and the second protective shell 72. The housing 72 forms a shield to prevent the splashed powder from falling onto the machine body 1, which would be inconvenient to clean and would also cause waste. At the same time, the shielded powder falls into the through hole 76 and then into the collection tank 78 through the funnel 77, thereby achieving the purpose of collecting part of the powder so that the staff can reuse the powder. Then, the second rack 75 is pulled, causing the second rack 75 to slide upward in the slide groove 74, driving the second gear 73 to rotate. The second gear 73 then drives the clamping plate 69 to rotate synchronously, thereby achieving the purpose of adjusting the angle of the hook, so that the cold spray powder is evenly sprayed on the hook, thereby improving the spraying efficiency.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
