【摘要】：矿井提升机是矿山机械重要设备之一，是地面与地下矿井间输送设备，它可完成生产物资与生产人员输送工作任务，被誉为“咽喉设备”。矿井提升机设计、加工及生产运行的情况，直接影响矿井企业能否安全生产甚至威胁人员生命安全。传统设计中，卷筒是矿井提升机的关键部件，其结构和性能一直是设计人员的关注点。卷筒部件受力复杂，设计计算工作量大、求解困难、产品研发周期长，设计中常采用大量简化及粗略计算方式，但其设计计算结构仅能反映卷筒部件某个局部应力、位移及强度和刚度，不能整体、综合的反映结果，为了达到安全生产，往往加大安全系数，造成不必要的浪费。随着数字化设计技术的发展，采用现代的设计方法代替传统设计是必然的。采用CAD与CAE技术可以缩短研发周期，使其设计与分析更符合生产实际，优化资源，避免造成资源浪费。本论文以矿井提升机卷筒为研究对象，通过运用SolidWorks、ANSYS Workbench软件及ANSYS中APDL语言，对卷筒部件设计与分析等关键技术展开研究。文中对卷筒部件关键的设计理论做了深入论述，，并以2JK-3×1.5型单绳缠绕式矿井提升机为例，对其卷筒部件设计中的结构方案、力学性能等关键技术问题进行研究。采用SolidWorks软件对卷筒部件进行实体建模；基于ANSYS Workbench软件对卷筒进行静力学与动力学分析，观察其分析结果是否满足力学性能要求，并对卷筒是否选择安装木衬及安装何种材料的衬板，进行深入对比分析，获得木衬厚度与材料影响卷筒部件应力的分布规律；基于幅板的受力特殊性，在ANSYS中进行拓扑优化；运用ANSYS中APDL语言，对卷筒部件中主要零件进行参数化建模与分析。与卷筒部件的传统设计、计算和分析对比，本论文所采用的方法减少了设计人员的工作量，同时提高其设计的准确性，缩短了产品研发周期，可为将来大型提升机卷筒设计的提供快速准确的设计方法与参考，增加企业的竞争力和效益。
[Abstract]:Mine hoist is one of the important equipment of mine machinery, it is the transportation equipment between ground and underground mine, it can complete the task of transporting production material and production personnel, and is called "throat equipment". The design, processing and operation of mine hoist directly affect the safety of mine production and even threaten the safety of personnel. In traditional design, reel is the key component of mine hoist, and its structure and performance have always been the focus of attention of designers. The design and calculation of reel parts are complicated, the design and calculation work is heavy, the solution is difficult, the product R & D cycle is long, a large number of simplified and rough calculation methods are often used in the design, but the design and calculation structure can only reflect some local stress of the reel parts. Displacement, strength and stiffness can not be integrated to reflect the results, in order to achieve safety in production, often increase the safety factor, resulting in unnecessary waste. With the development of digital design technology, it is necessary to replace traditional design with modern design method. The adoption of CAD and CAE technology can shorten the research and development cycle, make its design and analysis more in line with the actual production, optimize the resources and avoid the waste of resources. This paper takes the mine hoist reel as the research object, through the use of SolidWorks,ANSYS Workbench software and ANSYS APDL language, the design and analysis of reel parts and other key technologies are studied. In this paper, the key design theory of reel parts is discussed in depth. Taking 2JK-3 脳 1.5 type single rope winding mine hoist as an example, the structural scheme, mechanical properties and other key technical problems in the design of reel parts are studied. The SolidWorks software is used to model the reel parts. The statics and dynamics of the reel are analyzed based on ANSYS Workbench software, and the results of the analysis are observed whether it meets the requirements of mechanical properties, and whether the reel chooses to install the wood lining and the lining board of the material is compared and analyzed in depth. The stress distribution law of reel parts affected by wood lining thickness and material was obtained. Based on the stress particularity of the plate, the topology optimization is carried out in ANSYS, and the parametric modeling and analysis of the main parts in the reel parts are carried out by using the APDL language in ANSYS. Compared with the traditional design, calculation and analysis of the reel parts, the method adopted in this paper reduces the workload of the designers, improves the accuracy of the design, and shortens the product R & D cycle. It can provide fast and accurate design method and reference for the design of large hoist drum in the future, and increase the competitiveness and benefit of the enterprise.
