基于XY-8型钻机的分体与集成驱动模式设计优化及对比研究OA

With the advancement of a new round of mineral exploration breakthrough initiatives and the expansion of strategic mineral resource exploration to deeper areas,higher requirements have been put forward for deep-hole drilling equipment is required in terms of digitalization of drilling parameters,green and energy-saving,and human-machine friendliness.At present,XY-series mechanical spindle drills and full-hydraulic core drills dominate the domestic equipment for solid mineral exploration,which was still have a significant gap with advanced foreign levels in drilling parameter digitalization and green energy efficiency.Based on the XY-8 mechanical spindle drill,this paper explores and optimizes separated and integrated drive modes for the hoisting and rotary motions respectively,and develops the XY-8DB and XY-8DG digital spindle core drills by AC variable-frequency electric drive technology,combined with various electro-hydraulic signals and sensing technologies to enables multiple drilling parameters are digitally displayed and stored.These two drills have advanced driller control modes,which significantly improve the working environment for frontline personnel while enhancing the scientific nature of drilling.At the same time,by comparing and analyzing the technical characteristics,operating modes,costs,and applicable scenarios of the drills,it is concluded that using integrated drive mode has the advantages of higher digitalization level,lower installed power,and less one-time procurement investment compared to split drive mode.
