Abstract

This invention relates to the field of casting molten material containers with sliding gate nozzles, specifically to a combined device for installing and connecting a cylinder for a ladle sliding gate nozzle, and its usage method. The combined device includes a transport vehicle (11) and a ladle (12), characterized in that it further includes a cylinder seat assembly (2), a cylinder assembly (3), and a gripping device (4). The cylinder assembly (3) is mounted on the cylinder seat assembly (2) via a cylinder slot and fixed to the cylinder seat assembly (2) by a cylinder positioning and locking mechanism. The gripping mechanism (4) is mounted on a robot. The usage method of the combined device for installing and connecting a cylinder for a ladle sliding gate nozzle is characterized by the following steps: S1. Gripping the cylinder; S2. Fixing the cylinder; S3. Connecting the medium. This invention has a lightweight structure and high installation efficiency.
