[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.
