抓斗智能挖掘控制技术

Grab Bucket Intelligent Digging Control Technology

为解决散货门机在抓斗作业时超载保护频次偏高的问题,对四索双瓣抓斗建模和仿真,研究抓斗绳差与抓取量的关系,设计基于着床工况的抓斗姿态控制技术。建立挖掘数据模型,采用支持机力矩自动给定技术,优化抓斗挖掘控制策略,并探讨在其他场合的拓展应用。结果表明:抓斗智能挖掘控制技术能实时精准控制抓斗抓取量,可有效避免门机因超载保护造成的停顿,提高作业效率。

To solve the problem of bulk portal crane＇s higher frequency of overload protection during the grab operation, the modeling and simulation of four rope clamshell grab are carried out, the relationship between grab rope difference and grab quantity is researched and the grab bucket posture controlling technique based on implantation is designed. More ways are used such as setting up the data model of digging, using the automatic given technique of supporter force moment, optimizing controlling strategy of grab bucket digging and researching its expansion in other situation. It is shown that the grab bucket intelligent digging control technology can accurately control the grab quantity, effectively avoid the stop caused by overload protection and improve production efficiency.
