Analysis for wedge falling-proof brake assembly of lifter with converter oxygen lance

Designing wedge falling-proof brake assembly of the lifter to protect the converter oxygen lance and other equipments. This paper briefly introduces the design principle. Pro/Engineer-based parametric solid modeling for virtual assembly of the falling-proof brake assembly, and then motion simulation, the working process of the wedge falling-proof brake assembly demonstrated through the animation demonstration, so the simulation is accurate and clear; at the same time falling distance is derived from the rope broken to the lifter locked through mechanical analysis, and putting forward the measures to reduce falling distance of brake at last.
