一种立式退火炉炉底盖移除装置
By designing a furnace bottom cover removal device that combines a support frame with a hoist, the problem of safe and efficient disassembly and assembly of the bottom cover of a vertical annealing furnace in a narrow space was solved. This enabled the transfer without the need for an external power or pneumatic source, reducing the occupation of equipment spare parts and production costs, and improving operational efficiency and safety.

AI Technical Summary
In the existing technology, the mobile cover-lifting trolley cannot effectively dismantle and remove the bottom cover of the vertical annealing furnace in situations where the furnace bottom space is small, the removal path is narrow, and there are many obstacles. It poses a safety hazard and is limited by power or pneumatic sources, and cannot meet the need to remove multiple furnace covers at the same time.
A device for removing the bottom cover of a vertical annealing furnace is designed, which adopts a combination of a support frame and a hoist. The bottom of the support frame is equipped with casters, and the hoist is connected to the furnace shell to realize the suspension and slow descent of the bottom cover. The support frame is welded to the bottom cover, and the columns and beams are made of hot-rolled channel steel. Electric or manual hoists are used for hanging and transportation.
It enables safe and efficient assembly and disassembly of the furnace bottom cover in confined spaces, reducing the types of equipment and space occupation, lowering production costs, improving operational efficiency and safety, and avoiding interference with subsequent operations.
