Abstract

This invention relates to the field of mechanical automation assembly and coking equipment technology, specifically to a coal charging hole cover assembly device and method for use in sealed coke oven environments. It includes an annular rotary base and indexing turntable, a traveling pallet equipped with positioning columns and pneumatic self-centering claws, multiple workstations, and an industrial control computer. The device utilizes the indexing turntable to drive the clamped coal charging hole cover blank, which sequentially flows between workstations such as tamping and filling, welding, feeding and grinding, and bell jar testing. Its core is to achieve continuous flow of the workpiece based on a single reference point using the traveling pallet, and to utilize a positive pressure dustproof air curtain to blow away scattered refractory dust. This invention abandons the traditional multiple lifting method, overcomes the secondary clamping errors caused by realignment in harsh environments, ensures the cleanliness of the clamping surface, and improves the dimensional and positional accuracy of the workpiece throughout the assembly process.
