【摘要】：综采液压支架是一种利用液体压力产生支撑力并实现自行移动来进行顶板支护和管理的一种液压动力装置,是综合机械化采煤不可缺少的配套设备。传统综采液压支架的组装与拆除,多数采用手动葫芦作为起吊工具,这种方式安全隐患多、劳动强度大,组装与拆卸效率低,使得现在的安装拆卸进度严重落后于综采工作面的接替需要。为了安全、快速、高效地完成煤矿综采液压支架的组装与拆除工作,减轻工作人员的劳动强度,提高矿井的生产效率,亟需研发一种液压支架组装与拆除专用设备。论文研究的重点是：从液压支架组装与拆卸的高效性和安全性出发,开展综采液压支架组装架的结构设计,利用有限元分析软件ANSYS-Workbench对其关键部件进行有限元分析,验证结构的合理性与可靠性,完成液压系统的设计。具体内容如下：首先,论文从综采液压支架组装架的整体结构入手,利用Solidworks建立了其整机模型,并详细对起吊装置、纵向移动装置、侧翻装置及自移装置的功能和结构进行了介绍；其次,利用有限元分析软件ANSYS-Workbench对起吊装置的定链轮支座、侧翻装置的滑动支座及纵向移动装置的移动横梁进行了结构强度分析；再次,对自移装置的车轮轴进行了接触强度分析和模态分析,并对传动齿轮进行了瞬态动力学模拟；最后,对液压传动系统进行了设计,主要包括各回路执行油缸的负载分析、液压系统原理图的绘制及相关液压元件的选型设计工作。
[Abstract]:Fully mechanized mining hydraulic support is a kind of hydraulic power device which uses liquid pressure to produce support force and realize self-moving to support and manage roof. It is an indispensable supporting equipment for comprehensive mechanized coal mining. Traditional fully mechanized mining hydraulic support assembly and removal, most of which use manual hoist as a lifting tool, this method has many hidden dangers, high labor intensity, low efficiency of assembly and disassembly. So that the current installation and demolition progress seriously lags behind the replacement needs of fully mechanized mining face. In order to complete the assembly and removal of hydraulic support of fully mechanized mining in coal mine safely, quickly and efficiently, lighten the labor intensity of workers and improve the production efficiency of mine, it is urgent to develop a special equipment for assembling and removing hydraulic support. The research focus of this paper is: starting from the high efficiency and safety of assembling and disassembly of hydraulic support, the structure design of the assembly frame of fully mechanized mining hydraulic support is carried out. The finite element analysis software ANSYS-Workbench is used to carry out the finite element analysis of its key components. Verify the rationality and reliability of the structure, complete the design of hydraulic system. The concrete contents are as follows: firstly, the paper starts with the whole structure of the fully mechanized mining hydraulic support assembly frame, establishes its whole machine model by using Solidworks, and makes a detailed analysis of the lifting device, the longitudinal moving device, and so on. The function and structure of the roll-over device and the self-shifting device are introduced. Secondly, the finite element analysis software ANSYS-Workbench is used to analyze the structural strength of the fixed sprocket support of the lifting device, the sliding bearing of the rollover device and the moving beam of the longitudinal moving device. Thirdly, the contact strength and modal analysis of the axle of the self-shifting device are carried out, and the transient dynamic simulation of the transmission gear is carried out. Finally, the hydraulic transmission system is designed, which mainly includes the load analysis of each loop, the drawing of the hydraulic system schematic diagram and the selection of the relevant hydraulic components.
