Research On Mechanical Characteristic Of The ZC8800/20/38 Hydraulic Support

Hydraulic support is an equipment to ensure the safety of production in the process of coal mining,it is an important equipment to realize automation and mechanization of fully mechanized mining.When the hydraulic support works under different loading conditions,different working conditions,its mechanical performance will be greatly changed,in order to improve the reliability of hydraulic support,it is necessary to use the modern design theory and design method to analyze and study the main structural parts of the hydraulic support in the design process.This is conducive to grasp the main structural parts of each type of bracket weak links,more targeted to further optimize the design of the stent,improve the support performance of hydraulic support,it is of great theoretical significance and practical value to improve the safety of coal mine production.This paper studies the customized zc8800/20/38 gangue filling hydraulic support for the "three-lower" coal seam working face in a mining area.Firstly,according to the design principle of hydraulic support and the actual working condition of mining roadway in comprehensive mining area,the basic structure of hydraulic support for gangue filling is designed and the main working parameters are determined.According to the actual working conditions of the working face,the layout scheme of the equipment on the working face was determined,and the working conditions of the hydraulic support group were analyzed,the load of the roof was determined,and finally the load distribution and partial load coefficient of the hydraulic support at different positions along the direction of the working face were determined.According to the actual structure of the scaffold,the 3d model of the scaffold is built and assembled by software.Grid division and material property distribution were carried out on the basis of three-dimensional solid model,which was imported into the ANSYS simulation software.The research methods and conclusions adopted in this paper provide the means and theoretical basis for dynamic analysis and improved design of strong caving top coal support.
