【摘要】：广泛用于煤炭行业的液压支架,是机械化综采设备的关键部件。目前,我国的液压支架研究、使用水平处于国际前沿地位。但是,在大倾角综采工作面液压支架研究上,由于地质条件复杂,支架稳定性难以控制,造成适用于大倾角综放工作面的液压支架设计研发相对滞后。因此,本文以实习企业的“大倾角综采工作面液压支架优化研发”项目为研究背景,主要是解决支架的稳定性控制的技术难题,找到影响支架稳定性的因素,通过优化、仿真、有限元分析,使支架设计达到最优化,进而缩短产品设计制造周期,提高支架的可靠性。本课题通过研究大倾角支架与围岩作用关系,提出了大倾角液压支架应具备的特性,为液压支架优化设计提供了理论支持和分析依据。以虚拟样机仿真技术支持,建立并分析了ZZ4200/15/32型支撑掩护式液压支架关键零部件的有限元分析模型,对支架在不同受载情况下的强度进行了分析和校核,得出各种载荷特点、围岩关系和支架设计注意事项,进一步保证了支架结构安全、稳定。然后,在研究支撑掩护式液压支架的稳定性基础上,设计了有效的防倒防滑装置,并进行了组装验证,为今后支撑掩护式液压支架的防倒防滑装置的设计与研究奠定理论基础。
[Abstract]:Widely used in coal industry, hydraulic support is the key component of mechanized fully mechanized mining equipment. At present, the research of hydraulic support in our country is in the international forefront position. Because of the complex geological conditions and the difficulty in controlling the stability of the support, the design and development of the hydraulic support suitable for the fully mechanized caving face with large dip angle is relatively delayed. In this paper, based on the research background of "Research and Development of hydraulic support in large inclination fully Mechanized Mining face", the main purpose of this paper is to solve the technical problems of support stability control, to find out the factors that affect the stability of support, and to find out the factors that affect the stability of support through optimization and simulation. Finite element analysis can optimize the design of the support, shorten the design and manufacture cycle of the product, and improve the reliability of the support. By studying the relationship between the support with large inclination angle and surrounding rock, the characteristics of the hydraulic support with large dip angle are put forward. This paper provides theoretical support and analysis basis for the optimal design of hydraulic support. With the support of virtual prototype simulation technology, the finite element analysis model of key components of ZZ4200/15/32 type supporting cover hydraulic support is established and analyzed. The strength of the support under different loading conditions is analyzed and checked, and various load characteristics, surrounding rock relations and design considerations are obtained, which further ensure the safety and stability of the support structure. Based on the study of the stability of the supporting cover hydraulic support, an effective anti-skid device is designed, and the assembly verification is carried out, which lays a theoretical foundation for the design and research of the anti-skid device of the supporting cover hydraulic support in the future.
