Through the systematic analysis of the force of the wide and narrow rod and the hinged pin shaft at the protective devices of the hydraulic support,the optimization design theory method here is established,which solves the problem of the lack of theoretical analysis method in this link.At the same time,the analysis and calculation process is compiled to form a set of strength check program,which avoids the problem of repeated calculation and analysis.After optimization,the safety factor of the hinged pin shaft can be increased to 3~4 times of the original.
