【摘要】：立井施工提升机是矿井建设中的重要设备,其运行性能直接影响到矿井建设的速度以及人员安全问题,对调速控制系统进行优化改造是提高其安全稳定性的重要手段。中煤第五建设有限公司现存大量采用转子串电阻调速的立井施工提升机,由于经济效益不佳,进行设备升级的同时必须减少经费投入,所以需要在充分利用现存设备的基础上进行优化改造。据此,本文研究了立井施工提升机采用串电阻调速的工况适应性和能耗问题,并设计了一套立井施工提升机调速控制系统。首先,本文介绍了立井施工提升机调速控制技术的发展现状,并结合运动学和动力学方程对立井施工提升机采用六阶段速度图运行进行分析,总结出运行过程中各控制参数的确定方法;其次,分析了立井施工提升机采用转子串电阻调速实现提升货载和下放货载的工作原理及控制流程,并针对其工况适应性和能耗问题进行理论分析和仿真验证;然后,分析了控制系统的控制任务和功能要求,针对控制系统实时多任务的特点设计了基于分布式结构的立井施工提升机调速控制系统;最后,以AT89S8253单片机为核心,给出了主要功能单元的软硬件设计方案,包括重要接口电路设计、通信协议编写和软件功能实现,并利用组态王进行上位机软件设计。本文所研究的立井施工提升机调速控制系统,利用单片机控制取代原来继电器-接触器逻辑控制,提高了系统的运行效率和稳定性,并且利用组态王提供完善的人机交互界面,对系统的实时运行情况进行监测并记录,进一步提高了系统的可靠性。
[Abstract]:Shaft hoist is an important equipment in mine construction. Its running performance directly affects the speed of mine construction and the safety of personnel. Optimizing the speed control system is an important means to improve its safety and stability. There are a large number of shaft construction hoists in China Coal Construction Co., Ltd., which use rotor series resistance to adjust speed. Because of the poor economic benefits, it is necessary to reduce the cost of equipment upgrading at the same time. Therefore, it is necessary to optimize and transform on the basis of making full use of existing equipment. Based on this, this paper studies the adaptability and energy consumption of vertical shaft construction hoist using series resistance speed regulation, and designs a set of vertical shaft construction hoist speed regulation control system. First of all, this paper introduces the development of speed control technology of shaft hoist, and analyzes the operation of shaft construction hoist using six-stage velocity diagram combined with kinematics and dynamics equation. The methods of determining the control parameters during operation are summarized. Secondly, the working principle and control flow of hoist in shaft construction using rotor series resistance speed regulation to realize the lifting and lowering of cargo load are analyzed. Then, the control task and function requirements of the control system are analyzed. According to the real-time multi-task characteristic of the control system, this paper designs the speed control system of shaft hoist based on distributed structure, and finally, taking AT89S8253 single chip microcomputer as the core, gives the hardware and software design scheme of the main function unit. It includes important interface circuit design, communication protocol writing and software function realization, and use configuration King to design upper computer software. The speed control system of shaft hoist studied in this paper uses single chip computer control instead of the original relay contactor logic control, which improves the running efficiency and stability of the system, and makes use of configuration King to provide perfect man-machine interface. The real-time operation of the system is monitored and recorded, and the reliability of the system is further improved.
