摘要
配重机构作为工程吊管机的重要组成部分,一直采用的是人工操作的控制方式,在野外复杂环境下由于操作人员视野不足可能会导致配重收展的不及时,造成倾翻的危险。为了提高工程机械吊管机的自动化操作能力,以某型吊管机的配重机构为研究对象,首先分析其起吊力矩平衡模型,确立了油缸行程作为控制对象,运用CREO2.0建立数字化配重机构模型,仿真分析了配重展开的过程,并得到了油缸行程与配重质心位置的关系曲线,进一步通过起吊试验平台进行现场实际试验,验证了油缸行程与配重机构质心位置变化的线性比例关系具有其实际的可靠性。最终确立了以DSP为核心的系统控制模块,并根据控制对象的关系设计了配重自调节系统的控制策略,为吊管机配重机构的智能化控制提供了一种新的方法与依据。
Counterweight is an important part of engineeringmachine pipelayer,which has been operated by human beings for a long time.However,when the working circumstances are quite complex in the outside,the pipelayer is likely to turn upside down due to the vision limit of the operator as well as the not timely operation of counterweight.In order to improve the autooperation capability of pipelayer,a certain type of pipelayer counterweight mechanism has been studied in this paper.The oil cylinder stroke is confirmed as the control object by analyzing the lifting moment balance model.Then the Creo2.0 is used to build a digital counterweight model and simulate the stretching process of counterweight,a relation curve about the oil cylinder stroke and the barycenter position of counterweight is got from the simulation.To verify the practical reliability of the linear relation,a real experiment has been made via the lifting test platform.Finally,the system control module based on DSP is established and counterweight self-adjusting system control strategy is designed according to the relationship between control objects.This study provides a new method and a basis for the intelligent control of pipelayer counterweight mechanism.
