【摘要】：铁矿石开采是国民经济重要支柱性产业,为繁荣国民经济作出突出了贡献,而矿井提升机作为铁矿石开采运输的咽喉设备,自诞生以来,对提高矿物开采量和开采效率起着举足轻重的作用。本篇论文是以河北邢台中关铁矿项目为背景,通过实际项目调研,分析现场数据参数进行的主井提升机设计。本项目设计采用了当今先进的全数字直流调速方案、可靠的可编程逻辑控制系统,以及安全的算法逻辑方案,全程以“安全第一”为原则来设计硬件结构和控制系统,在保证人车安全和优异设计的基础上,实现了节约成本的目的。论文主要阐述了中关铁矿主井提升机的设计参数,分析了提升机控制系统工艺要求,介绍了提升机工作流程和控制工艺,介绍了提升机的速度-行程控原理以及相关速度计算和行程计算,介绍了矿井提升机的设备布局方案。在此基础之上,首先,阐述了十二脉整流器方案原理、谐波分析和处理、整流器参数设定值及不同参数的影响;其次,阐述了矿井提升机的硬件结构和设计原理;再次,阐述了矿井提升机的工艺算法设计原理;最后,阐述了现场调试的过程和遇到的问题,以及问题的解决方案。另外,在本项目中尝试了具体工程先采用平台仿真,然后分析控制方案可行性,最后将具体设计方案应用到实际工程的模式。这种模式不仅节约了设计成本,而且避免了许多现场调试事故,减少器件损坏数量,并借助虚拟仪器弥补了设计方案的潜在性漏洞,在具体工程项目中效果显著。现场调试表明,主井提升机系统工作可靠、响应速度快、控制精度高,能够完全胜任现场各项工作任务。
[Abstract]:Iron ore mining is an important pillar industry of the national economy and has made outstanding contributions to the prosperity of the national economy. Since its birth, the mine hoist has been used as a throat equipment for iron ore mining and transportation. It plays an important role in improving mineral exploitation and mining efficiency. Based on the project of Zhongguan Iron Mine in Xingtai, Hebei Province, this paper analyzes the design of main shaft hoist based on actual project investigation and analysis of field data parameters. The design of this project adopts the advanced all digital DC speed regulation scheme, the reliable programmable logic control system, and the safe algorithm logic scheme. The hardware structure and control system are designed based on the principle of "safety first". On the basis of the safety and excellent design of the guarantor, the purpose of cost saving is realized. This paper mainly describes the design parameters of the hoist in the main shaft of Zhongguan Iron Mine, analyzes the technological requirements of the hoist control system, and introduces the work flow and control technology of the hoist. This paper introduces the principle of speed-travel control of hoist, the calculation of relative speed and stroke, and the layout scheme of mine hoist. On this basis, firstly, the principle of the 12-pulse rectifier scheme, harmonic analysis and treatment, the parameter setting value of the rectifier and the influence of different parameters are expounded. Secondly, the hardware structure and design principle of the mine hoist are expounded. Thirdly, The design principle of technological algorithm for mine hoist is expounded, and finally, the process of field debugging, the problems encountered and the solutions to the problems are expounded. In addition, the platform simulation is used in the project, and then the feasibility of the control scheme is analyzed. Finally, the concrete design scheme is applied to the actual engineering mode. This mode not only saves the design cost, but also avoids many on-site debugging accidents, reduces the number of device damage, and makes up the potential loophole of the design scheme with the help of virtual instrument. Field debugging shows that the main shaft hoist system is reliable, fast response, high control precision, and can be fully competent for all kinds of work tasks in the field.
