| Abstract: | Taking mine 280 type doubly-telescopic prop technical parameters as the basis,through the establishment of a two-dimensional model,according to the structural characteristics of doubly-telescopic prop,through the thickness,stability and strength of the piston rod calculation to verify the technical parameters can satisfy the operation requirements.The calculation results show that: the calculation method is reasonable,the type of double telescopic column with high safety factor,can provide similar design foundation to large doubly-telescopic prop. |
