【摘要】：圆型堆取料机是水泥,电力,煤炭企业圆型料场的预均化设备,是保证企业连续生产的关键设备,圆型堆取料机的性能直接决定企业产品的稳定性和可靠性。因此保证圆型堆取料机的机构和结构的先进性是改进设备整体性能的前提。本文以河南煤业集团的实际项目为工程背景,对现有的80米圆形料场堆取料机进行了深入分析与研究,提出改进方案,完成新设计,并实施于产品的实际研制中。本文首先收集和研究国内外相关文献,阐述了80米圆型料场堆取料机现有组成与工作原理。其次在分析现有的结构机构形式基础上,对料场储量空间、行走驱动机构和回转驱动机构等提出相应改进方案,使机构更为紧凑、整机性能有效提高。最后对堆取料机的钢结构进行设计,并建立有限元模型,校核分析结构的强度与刚度,对比分析了改进前后结构的应力状态,以表明改进后结构的合理性。通过实际产品的试制与应用,进一步表明改进后的结构机构的可行性。
[Abstract]:The circular stacker is the pre-homogenization equipment of the circular material yard in cement, electric power and coal enterprises, and is the key equipment to ensure the continuous production of the enterprise. The performance of round stacker directly determines the stability and reliability of enterprise products, so it is a prerequisite to improve the overall performance of the equipment to ensure the advancement of the mechanism and structure of the circular stacker. Taking the actual project of Henan Coal Industry Group as the engineering background, this paper makes a thorough analysis and research on the existing 80m circular material yard heap-collecting machine, puts forward the improvement scheme, completes the new design, and implements it in the actual development of the product. This paper first collects and studies the relevant literature at home and abroad, and expounds the existing composition and working principle of the 80 meter round yard stacker. Secondly, on the basis of analyzing the existing structural mechanism, the paper puts forward the corresponding improvement schemes for the reserve space of the material farm, the walking drive mechanism and the rotary drive mechanism, so that the mechanism is more compact and the performance of the whole machine can be improved effectively. Finally, the steel structure of the stacker is designed, the finite element model is established, the strength and stiffness of the structure are checked and analyzed, and the stress state of the structure before and after the improvement is compared and analyzed to show the rationality of the improved structure. The feasibility of the improved structure mechanism is further demonstrated by the trial production and application of the actual product.
