1986年4月至5月,我有幸随水电部赴阿特拉斯·科普柯(Atlas Copco)公司考察组去瑞典考察,参观访问了该公司的制造厂,产品试验场,应用该公司产品施工的水电站、核电站、地下铁矿、建筑工地等。该公司有不少产品闻名于世,其中凿岩机和钻机的地位尤其重要。在各种钻机中,带有履带底盘的自行式液压钻机应用甚广,其特点是作业效率高,施工质量好,机动灵活,施工适应性好。阿特拉斯·科普柯公司的履带式液压钻机有三个系列:ROC400、ROC700和 ROC800,每个系列中又有若干规格型号。几个典型品种的技术参数见表1。
From April to May 1986, I had the privilege of visiting the Atlas Copco inspection team with the Ministry of Hydropower to visit Sweden. I visited and visited the company’s manufacturing plant, product testing ground, and applied the company’s product construction. Hydropower stations, nuclear power stations, underground iron mines, construction sites, etc. The company has many products known around the world, of which rock drills and rigs are particularly important. Among various drilling rigs, self-propelled hydraulic drilling rigs with crawler chassis are widely used. They are characterized by high working efficiency, good construction quality, flexible maneuverability, and good construction adaptability. Atlas Copco’s crawler hydraulic drilling rigs are available in three series: the ROC400, ROC700 and ROC800. There are several models in each series. The technical parameters of several typical varieties are shown in Table 1.
