内容简介：

摘 要本文的课题是8.9米一次性采全高液压支架的总体设计。液压支架作为采煤工作面的重要支护设备，在工作过程中能否取得良好的支护效果，取决于支架的架型，结构和相关参数。联系实际，本文将为神东设计一款支护高度达到8.9米的大采高液压支架。设计首先通过计算，分析和比较，确定了液压支架的顶梁、底座等基本尺寸，然后通过几何做图法进行四连杆机构优化设计来确定支架的四连杆机构各杆系的长度,之后优选各部件，画出草图，进行受力分析，并进行强度验算。最后确定液压支架的型号 确定配套装置，绘制装配图及零件图。在完成设计的过程中，利用理论分析的同时，也采用了许多实际经验，做到理论与实践相结合。关键词：掩护式支架；8.9米大采高；四连杆；立柱；优化设计；强度AbstractTopic of this paper is 8.9 m one-time mining overall height hydraulic supports the overall design.Hydraulic support as coalface important support equipment, in the work process can achieve good supporting effect, depending on the stand of the frame type, structure and related parameters. With practice, this paper will design a support Shendong height of 8.9 meters of large mining height hydraulic support. Design is first calculated, analyzed and compared to determine the roof beams, hydraulic support base and other basic dimensions, and then optimize the four-bar linkage design do figure geometric method to determine the length of each stand four-bar linkage rod system, after preferably, each member, sketch, stress analysis, and checking the strength. Finalize the hydraulic model to determine the bracket supporting devices, assembly drawing and part drawing.In the completion of the design process, the use of theoretical analysis, but also with a lot of practical experience, so that the combination of theory and practice.Key words: cover timbering; 8.9 meters large mining height are b
