液压支架护帮机构对防止煤壁片帮起着极其重要的作用。在对改进前和改进后ZY3800/16/35型液压支架单铰点护帮板机构进行有限元受力分析,得到:1护帮板设计应去掉缺口;2为了保证强度,护帮板顶应力较大处应采用长条板加强;3护帮板设计应从结构、材料、工艺方面综合考虑。为今后指导此类护帮机构的设计及材料选用提供了依据。
Hydraulic bracket guard agencies to prevent the coal wall plays an extremely important role. Before and after the improvement of the ZY3800 / 16/35 type hydraulic support single hinge point of the hull plate was subjected to finite element stress analysis, we get: 1 hull design should be removed gaps; 2 in order to ensure the strength of the hull stress The larger should be used to strengthen the long strip; 3 care board design should be from the structure, materials, technology considerations. This will provide the basis for guiding the design and material selection of such care providers in the future.
