HRD800F型水平岩心钻机动力头的研制

Development of power head for HRD800F horizontal core drill

自然资源部找矿办装备组开展了找矿装备调研和国内外找矿技术装备对比分析研究。结果表明,历经数十年积累,我国勘查技术装备的发展虽然取得了进步,但仍存在一些短板和挑战。总体上,目前我国地勘队伍装备陈旧,绿色先进装备配备少,先进仪器设备以进口为主,国内研发保障能力不足,装备产业化水平不高,野外生活安全保障条件差,亟需加强找矿装备建设,支撑全面推进绿色勘查,满足新一轮找矿突破战略行动的找矿装备新需求。自然资源部中国地质调查局率先加快构建现代化野外条件保障体系,先后制定了《关于加强地质调查野外综合保障基地使用的指导意见》等制度文件,主要任务是推动绿色勘查、缩短与国外先进装备水平的差距。为适应新一轮战略找矿行动和国家重大工程勘察精细化对装备的要求,我们研制了HRD800F型水平岩心钻机。动力头是岩心钻机的关键部件,本文阐述了该型号岩心钻机动力头设计方案和设计过程以及测试过程,并总结了该动力头的性能特点。

The Equipment Organization of the Mineral Exploration Office of the Ministry of Natural Resources has conducted research on mineral exploration equipment and comparative analysis of mineral exploration technology and equipment at home and abroad.The results indicate that after decades of accumulation,although progress has been made in the development of exploration technology and equipment in China,there are still some shortcomings and challenges.Overall,the current geological exploration team in China is equipped with outdated equipments,limited green advanced equipments,and mainly imported advanced instruments and equipment.The domestic research and development support capacity is insufficient,the level of equipment industrialization is not high,and the safety guarantee conditions for field life are poor.It is urgent to strengthen the construction of mineral exploration equipments,support the comprehensive promotion of green exploration,and meet the new demand for mineral exploration equipment in the new round of breakthrough strategic actions.The China Geological Survey Bureau of the Ministry of Natural Resources has taken the lead in accelerating the construction of a modern field condition guarantee system,and has successively formulated institutional documents such as the Guiding Opinions on Strengthening the Use of Geological Survey Field Comprehensive Support Bases.The main task is to promote green exploration and shorten the gap with advanced equipment levels abroad.To meet the requirements of the new round of strategic mineral exploration and the refinement of national major engineering surveys,the HRD800F horizontal core drill was developed.The power head is a key component of a core drilling rig.This article elaborates on the design scheme,design process,and testing process of the power head for this type of core drill,and summarizes the performance characteristics of the power head.
