Description

Technical Field

[0001] This utility model relates to the technical field of hot-dip galvanizing production equipment, specifically to a rail-aligned and curved rail hybrid production line. Background Technology

[0002] Hot-dip galvanizing is a commonly used metal corrosion protection technology, widely applied in the processing of workpieces such as rails and steel structures. During the hot-dip galvanizing production process, the logistics efficiency and ease of operation of the production line directly affect production efficiency and product quality.

[0003] Currently available hot-dip galvanizing production lines suffer from low logistics efficiency during material transfer. This is primarily due to the fixed transfer path after material handling, making it difficult to flexibly adapt to the needs of different processes. While some circular production lines offer advantages in logistics continuity, their complex loading station setup and cumbersome operation require significant manual intervention. This not only increases the workload of operators but also increases the risk of production delays due to operational errors, failing to meet the demands for efficient and stable production. Therefore, there is an urgent need for a hot-dip galvanizing production line that balances logistics efficiency with ease of operation. Utility Model Content

[0004] This utility model aims to solve the above-mentioned technical problems by providing a rail-aligned and curved rail mixed production line.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: A mixed production line for both straight and curved tracks includes a pre-processing area, curved tracks, a zinc pot, and a monorail hoist. The pretreatment area includes a sealed chamber, several solution tanks, and pretreatment tracks arranged opposite each other on the sealed chamber, with movable monorail hoists installed on the pretreatment tracks. The monorail hoist feeds the material into several solution tanks for pretreatment via a pretreatment track. The sealed chamber is equipped with an inlet door and an outlet door. A secondary loading and unloading area is set between one side of the outlet door and the zinc pot. Multiple rail-aligned trolleys are set at the outlet door. The rail-aligned trolleys are used to lift the pre-processed workpieces to the secondary loading and unloading area or to directly lift and connect the curved rails. The trolley is equipped with a hoisting track that can be connected to a curved track, and a monorail hoist can move along the hoisting track. The monorail hoist can move along the hoisting track to the first curved rail interface of the curved track, and then pass through a zinc pot for galvanizing along the curved track. The monorail hoist can return to the hoisting track of the trolley along the second curved rail interface of the curved track.

[0006] Preferably, the solution tank is set in a sealed room, and the solution tank is used to hold the pretreatment process solution. The workpiece to be plated is placed in the solution tank for immersion, and the monorail hoist is used to move the workpiece to be plated between several solution tanks to complete the pretreatment process.

[0007] Preferably, the production line also includes several loading areas, through which the workpieces to be plated are transported to the sealed chamber via a ground conveyor or a rail-mounted trolley.

[0008] Preferably, the solution tank includes a degreasing tank, a plurality of first washing tanks, a plurality of acid tanks, a plurality of second washing tanks, and a plating flux tank.

[0009] Preferably, the zinc pot is located below the curved track, and a cooling pool and a passivation pool are also provided below the curved track.

[0010] Preferably, the cooling pool is located on the side of the zinc pot away from the secondary replacement area, and the passivation pool is located on the side of the cooling pool away from the zinc pot.

[0011] Preferably, the production line further includes a zinc fume dust collector and a spray tower. The zinc fume dust collector is used to absorb zinc fumes generated in the zinc pot area, and the spray tower is connected to a sealed chamber via a pipeline to absorb harmful gases generated in the sealed chamber.

[0012] This utility model also relates to a galvanizing method for a mixed production line of rail and curved rail, comprising the following steps: Loading process: Place the workpiece to be plated on the workpiece hanger, and transport the workpiece hanger from any loading area to the feed door of the sealed room by a ground conveyor vehicle. After the feed door is opened, the workpiece hanger is lifted into the sealed room by a rail trolley and hung on the hook of the monorail hoist. Pre-treatment process: Control the monorail hoist to move along the pre-treatment track set opposite to each other on the sealed chamber, and send the workpiece hanger into the degreasing tank, the first water washing tank, the acid tank, the second water washing tank and the fluxing tank in the sealed chamber in sequence, so that the workpiece to be plated is immersed in each tank for a preset time, and the pre-treatment process of degreasing, water washing, acid washing, water washing and fluxing is completed; at the same time, the spray tower connected to the sealed chamber through the pipeline is started to continuously absorb the harmful gases generated in the sealed chamber; Transfer process: After pretreatment, the monorail hoist moves the workpiece hanger to the discharge door of the sealed room, opens the discharge door, and the workpiece hanger is lifted by the rail trolley. If the subsequent process is not ready, the workpiece hanger is temporarily stored in the secondary swapping area between the discharge door and the zinc pot. If the subsequent process is ready, the rail trolley is controlled to move the workpiece hanger so that the lifting track on the rail trolley is aligned with the curved track interface. Then the monorail hoist is controlled to move the workpiece hanger along the lifting track to the curved track. Galvanizing and subsequent processes: Control the monorail hoist to move along the curved track and send the workpiece hanger into the zinc pot located below the curved track for hot-dip galvanizing. Start the zinc fume dust collector to absorb the zinc fumes generated during the galvanizing process. After galvanizing, the monorail hoist drives the workpiece hanger to move along the curved track to the cooling pool on the side of the zinc pot away from the secondary hanging area for cooling. After cooling, it is moved to the passivation pool on the side of the cooling pool away from the zinc pot for passivation. Unloading and Resetting Process: After passivation, the monorail hoist moves the workpiece hanger along the curved track to the second curved track interface. The hoisting track of the rail trolley is then aligned with the second curved track interface. The monorail hoist moves the workpiece hanger onto the hoisting track, where it is hoisted by the rail trolley to the unloading station for unloading. After unloading, the monorail hoist returns to its initial position along the hoisting track and the pre-processing track. The rail trolley resets to the discharge gate, ready for the next batch of production.

[0013] The first washing tank is set in two groups, the acid tank is set in eight groups, and the second washing tank is set in two groups.

[0014] By adopting the above structure and method, this utility model has the following advantages: 1. Improve logistics efficiency: By setting up pre-processing tracks, hoisting tracks, and curved tracks, in conjunction with monorail hoists and rail-aligning trolleys, automated material transfer between various processes is achieved, eliminating the need for extensive manual assistance, reducing material transfer time, and improving overall logistics efficiency; the setting of a secondary swapping area enables flexible material scheduling, avoids material accumulation, and further ensures smooth production.

[0015] 2. Simplified operation process: The setting of multiple feeding zones facilitates the material feeding operation, and operators do not need to frequently adjust the feeding position; the precise docking between each track and the automated movement of the monorail hoist reduce the difficulty of operation, reduce operational errors, and lower the technical requirements for operators.

[0016] 3. Excellent environmental performance: The zinc fume dust collector and spray tower effectively treat the zinc fumes generated in the zinc pot area and the harmful gases generated in the sealed room, reducing the emission of harmful gases and reducing environmental pollution, which meets the environmental protection requirements of modern industrial production.

[0017] 4. High product quality: By sequentially setting up a degreasing tank, a first water washing tank, an acid tank, a second water washing tank, a fluxing tank, a zinc pot, a cooling tank, and a passivation tank, the workpiece is treated in a comprehensive and multi-process manner, ensuring the cleanliness of the workpiece surface and the quality of the zinc coating, thereby improving the corrosion resistance and service life of the product.

[0035] The working principle of this utility model: Loading process: The operator places the workpiece to be plated on the workpiece hanger, and the workpiece hanger is transported from any loading area to the feed door of the sealed chamber 3 by the ground conveyor vehicle. The feed door is opened, and the workpiece hanger is lifted into the sealed chamber 3 by the rail trolley 7 and hung on the hook of the monorail hoist 5.

[0036] Pre-treatment process: The monorail hoist 5 moves along the pre-treatment track 4 and sequentially sends the workpiece hanger into the degreasing tank, the first water washing tank, the acid tank, the second water washing tank and the fluxing tank.

The monorail hoist 5 moves the workpiece hanger onto the hoisting track 8, and the rail trolley 7 lifts it to the unloading station for unloading.

[0039] Track reset process: After unloading is completed, the monorail hoist 5 returns to its initial position along the hoisting track 8 and the pre-processing track 4, waiting for the hoisting of the next batch of workpieces. The rail trolley 7 is also reset to the discharge gate, ready for the next hoisting operation.
