几年来,一○六队在钻探施工中创造推广了不少的技术革新经验,同时也学习使用了一些外单位行之有效的革新成果.这些经验在提高钻探效率、保证质量、减轻劳动、安全生产、节约材料等方面起了很大的作用.为了交流和进一步充实这些革新经验,现总结介绍如下,供各单位参考试用.一、钻机改进方面(一)大眼卡盘手把式给进的钻机如KAM-500、KA-2M-300等型式,是借助立轴上下卡盘夹紧钻杆,廻转钻进的.因而,每当钻进一个齿筒的有效长度以后,就需要松改卡盘顶丝,用手把压给进齿轮倒立轴齿筒,然后再卡紧钻杆继绩钻进,这样不仅增加辅助时间,而且经
In the past few years, 106 teams have created a lot of experience in technological innovation during drilling and construction, as well as learned some effective innovations made by outside agencies in enhancing drilling efficiency, ensuring quality, reducing labor and safety Production, material conservation, etc. In order to exchange and further enrich these experience of innovation, are summarized as follows, for reference for each unit trial .One, drilling improvements (a) big eye chuck hand-type Such as the KAM-500, KA-2M-300 and other types of drilling rig, is through the shaft up and down the chuck clamping chuck, 迴 turn drilling. Therefore, whenever the effective length of a gear after drilling, you need to loose Chuck top wire, hand pressure into the gear upside down shaft gear, and then chuck drill continued succession drilling, so that not only increase the auxiliary time, and by
