Outline
To meet the requirements for improving the load capacity and operational efficiency of the auxiliary shaft hoisting system in mines, the extra-large cage for modern mine auxiliary shaft was designed and studied based on the finite element method. The mechanical performance of the overall cage and its key components under a fully loaded condition of 150 t was systematically evaluated by establishing a three-dimensional solid model and conducting static simulation analysis using the ANSYS Workbench platform. The results indicate that the maximum equivalent stress of the overall cage is 47.749 MPa, and the overall safety factor, calculated based on the yield strength of Q690 steel, is 14.45. The safety factors of the main beams, columns, and tail beam are 16.3, 19.9, and 20.4, respectively, all of which are above the design control value nmin=13 and are in compliance with the safety regulations. The structural stress distribution is reasonable, and the deformation is controllable. It is demonstrated by engineering application that the overall transportation capacity and operational safety of cage for large-scale equipment can be improved by the design, and that a systematic design method from design constraints, load transfer paths, global structural response, local strength verification to engineering validation is established, and a reference is provided for the structural design of extra-large hoisting cages in deep mines.
