摘要
针对现有的石油钻杆输送装置提升绞车主要为液压驱动,其系统易受气温和环境的影响,系统稳定性较差,反应不灵敏,需要单独的液压站,不便于拆装和搬运等问题,设计了一套基于可编程逻辑控制器(Programmable Logic Controller,PLC)的双变频电控绞车系统作为钻杆输送装置的主驱动。使用三维软件建立电控绞车滚筒结构模型,并对其进行强度校核计算,基于ANSYS Workbench软件进行有限元仿真分析,其强度符合要求。该系统采用PLC作为控制器,利用模拟量信号控制变频器,从而同步控制双变频电机,以实现对电控绞车滚筒的控制。该系统自动化程度高、操控方便且安全稳定,避免了液压驱动系统的诸多不便,提高了钻杆输送及钻井的整体效率。
Aiming at the problems that the existing oil drilling pipe conveying device hoisting winch is mainly driven by hydraulic pressure,its system is easily affected by temperature and environment,system stability is poor,the response is not sensitive,a separate hydraulic station is needed,the device is not easy to disassemble and transport,a set of double frequency conversion electric control winch system based on Programmable Logic Controller(PLC)was designed,which served as the main drive of the drilling pipe conveying device.Three-dimensional software was used to establish the drum structure model of electric control winch,and its strength was checked and calculated.Based on finite element simulation analysis of ANSYS Workbench software,the strength meets the requirements.The system used PLC as the controller,and used analog signal to control the frequency converter to synchronously control the double frequency conversion motor,and realized the control of the electric control winch drum.The system is highly automated,easy to operate,safe and stable,avoids many inconveniences of hydraulic drive system,and improves the overall efficiency of drilling pipe conveying and well drilling.
