DQ-90型顶驱上卸扣装置的自动化控制研究

摘要

Top drive dril ing system is comprised of the carriage and guide beam, the transmission /motor housing ( main body) and swivel assembly and the make up and breaks out device. This article proposes that siemens programmable control er S7-300PLC is used to study the scheme of the automation control according to the working principle and the movement of the make-and-break de-vice in DQ-90 top drive dril ing system. This scheme includes the selection of control hardware configuration for each woking mecha-nism and fieldbus connection. After the hardware connection is determined, the program is written in STEP7 SIMATIC Manager ac-cording to the working principle and the movement of the device and the address of the coil and the switches of the PLC. Thus the make up and break out device is made get into the automatic control.%顶驱装置由导轨-导向滑车总成，水龙头-钻井马达总成和钻杆上卸扣装置三大部分构成。根据对其DQ-90型顶驱钻杆上卸扣的工作原理及运动情况分析，提出了用西门子可编程控制器S7-300PLC对其自动化控制的方案。该方案包括各个工作机构控制硬件配置的选用和现场总线的连接设计，待硬件配置连接确定后，根据上卸扣的工作流程及PLC开关和线圈的接线地址进行控制部分的程序编写。程序调试在STEP7-SIMATIC Manager 中进行，最终以达到上卸扣装置自动化控制的目的。
