| This paper introduces a new type of self moving type tunnel auxiliary safety support device-roadway hydraulic support, and it cooperate development machine that accelerate the progress of development working, in the metal support when using fast safe recycling mine timber. It support roof, role in the development working and permanent support between the time or recovery of metal support in front of the support, for underground operation personnel and equipment to provide security for the solid protection. First of all, in the tradition of working removing hydraulic support and the end support on the basis of the study, roadway hydraulic support using innovative arched net box beam. It has the structure simply, is self-possessed lightly that can be in the roadway at the same time using the rules of the hole for the bolt support in the support directly under, holes can also anchor position waste recycling; roadway support process is reverse, safe and reliable, economic benefits is good; the base for the split type symmetrical design, facilitates the bracket to move and other roadway operation device in parallel. Secondly, the use of Pro/E build roadway hydraulic support parameterization model, combined with VBA carried out two times the development, rapid modification of the model, designed to speed up the progress of the development of. Finally, through the Pro/E and ANSYS software between seamless model transformation, the mesh model is too complex, not rapidly dividing grid, need special treatment, which is not conducive to the future optimization, through consulting a large number of data, using the ANSYS Workbench for finite element simulation because the model is too complex effect is obviously better than ANSYS classic. The support in the received the largest roof load under the pressure of the deformation and stress cloud diagram, the strength and stiffness, to provide a theoretical basis for the feasibility of design. To sum up, the significance of this paper lies in:study design of hydraulic support top beam structure model, established for easy analysis parametric parts and assembly model, and the static analysis and modal analysis. Support a simple light, speed up the roadway operating speed, improve the labor production efficiency. It will make tunnel temporary support more scientific, advanced, practical and standardization. |
