【摘要】：全液压钻机具有结构紧凑、传动平稳以及易实现无级变速等优点,在基础工程施工、地质勘探测量、煤矿瓦斯抽放等领域得到了广泛应用。目前,液压钻机大多采用定量泵+溢流阀的手动操作控制方式,这种控制方式虽然在原理上简单易懂,但系统的能量利用率、安全性能以及工作效率都已经不能满足现代生产的需要。因此,本文将负载敏感控制技术与PLC自动控制技术引入全液压钻机液压系统中,研究系统的动静态性能,其成果对于提高国产钻机生产效率,降低事故率,提高国产钻机自动化水平有着十分重要的研究价值。本文在分析全液压钻机手动控制方式的基础上,以ZDY540型全液压钻机为对象,对负载敏感技术与自动控制技术在全液压钻机中的应用进行研究,针对ZDY540型钻机参数与性能设计了负载敏感液压系统与PLC自动控制系统,并对所设计的系统进行了理论分析与计算机仿真分析。在此研究基础上将模糊免疫自适应算法引入钻机负载敏感液压控制系统中,设计了模糊免疫自适应PID控制器,利用计算机仿真软件Matlab/Simulink搭建仿真模型,仿真结果表明该算法对于改善系统控制性能具有较大的作用。最后在实验室环境搭建实验平台进行实验,实验结果验证了所设计的负载敏感液压系统与自动控制系统在全液压钻机应用的有效性。通过本文理论与实验研究,验证了负载敏感控制技术与PLC自动控制技术在全液压钻机中应用的可行性,将模糊免疫自适应控制算法引入钻机压力控制系统,仿真结果表明其控制性能的优越性。研究成果对全液压钻机的自动化、智能化方向发展提供了理论指导。
[Abstract]:Full hydraulic drilling rig has the advantages of compact structure, stable transmission and easy to realize stepless speed change. It has been widely used in the fields of foundation engineering construction, geological exploration and survey, coal mine gas drainage and so on. At present, the hydraulic drilling rig mostly adopts the manual operation and control mode of the quantitative pump relief valve. Although this control mode is simple and easy to understand in principle, the energy utilization ratio of the system is very high. Safety performance and working efficiency can no longer meet the needs of modern production. Therefore, the load-sensitive control technology and PLC automatic control technology are introduced into the hydraulic system of the full hydraulic rig, and the dynamic and static performance of the system is studied. The results can improve the production efficiency of the domestic drilling rig and reduce the accident rate. It is very important to improve the automation level of domestic drilling rig. Based on the analysis of manual control mode of full hydraulic drilling rig, the application of load sensitive technology and automatic control technology in full hydraulic drilling rig is studied in this paper, taking ZDY540 type full hydraulic drilling rig as an object. The load-sensitive hydraulic system and PLC automatic control system are designed for the parameters and performance of ZDY540 drilling rig. The theoretical analysis and computer simulation analysis of the designed system are carried out. On the basis of this research, the fuzzy immune adaptive algorithm is introduced into the load sensitive hydraulic control system of drilling rig. The fuzzy immune adaptive PID controller is designed, and the simulation model is built by using the computer simulation software Matlab/Simulink. The simulation results show that the algorithm has a great effect on improving the control performance of the system. Finally, the experiment platform is built in the laboratory environment, and the experimental results verify the effectiveness of the designed load sensitive hydraulic system and automatic control system in the full hydraulic drilling rig. Through the theoretical and experimental research in this paper, the feasibility of applying load sensitive control technology and PLC automatic control technology in full hydraulic drilling rig is verified. The fuzzy immune adaptive control algorithm is introduced into the drilling rig pressure control system. The simulation results show that its control performance is superior. The research results provide theoretical guidance for the automation and intelligent development of full hydraulic drilling rig.
