属全路首创的ZGP60—1型三孔钻眼机,日前通过了济南局技术鉴定。 由徐州工务一段研制的该机,与现有钻眼机相比,具有体积小、重量轻、携带方便、钻孔工序简便、更换钻头方便、钻孔冷却稳定等优点,并具有钻小孔、钻半孔、修偏孔和一次钻三孔的特殊功能。通过现场施工使用证明,该机一人操作即可,一次断轨处理钻孔减少到12分钟左右,比原来提高4.5倍,精度可达±0.5毫米,可连钻40孔,
ZGP60-1 is a three-hole boring machine pioneered by the whole road and recently passed the technical appraisal of Jinan Bureau. Compared with the existing drilling machine, the machine developed by Xuzhou Works has the advantages of small size, light weight, easy to carry, simple drilling procedure, convenient replacement of drill bits, stable cooling of drilling holes, etc., and has the advantages of drilling small holes, Drill a half hole, repair hole and drill a special function of three holes. Through the use of on-site construction shows that the machine can operate one person, a track cut to reduce the drilling to 12 minutes or so, 4.5 times more than the original accuracy of ± 0.5 mm, with drilling 40 holes,
