AI Technical Summary
When changing rolls in an inclined casting and rolling mill, the mill needs to be rotated to a horizontal position. However, the universal joint and the roll head may jam in the inclined state, causing damage to the equipment.
The system employs a guiding mechanism and a flat-push mechanism. Through a telescopic transmission mechanism, the pull rod is pushed, which in turn pushes the traction rod connected to the roll system, causing the roll head to disengage from the universal joint shaft. This ensures that the casting and rolling mill can be stably rotated to a horizontal position, facilitating roll system replacement.
It enables stable and reliable roller system replacement, reduces production accidents, lowers equipment costs and failure rates, and avoids the need for new mechanisms and detection components.
