摘要:
目前在普查踏勘阶段,地质工作者要求随时随地取样,迫切地需要迁移便捷、快速钻进、高效高质的便携式取样钻机。本文介绍了研制的TGQ背包式取样钻机的参数、特点及试验情况。该钻机体积小、质量轻、结构设计合理,具有高、低两挡转速,可以实现金刚石钻进、螺旋钻进工艺,可以进行斜孔钻进取心,可以解决复杂地层的取样问题。钻具采用高强度的材料,钻杆采用插装式快速连接结构,提高了加减钻杆的效率。钻机的研制打破了国外背包式轻便钻机对我国市场的垄断。

Abstract:
Sampling is required anywhere at anytime in the geologic survey and reconnaissance stage, it is necessary to de-velop portable sampling drill with the characteristics of convenient relocation, high efficiency and high quality.This paper introduces TGQ knapsack sampling drill about its parameters, features and the related tests.With the characteristics of small size, light weight, high and low gear speeds by reasonable structure design, the rig can realize diamond drilling and auger boring, take core in inclined hole and take sample in complex stratum.The drilling tools are made of high strength materials and rapid plug-in type connecting structure is used on drilling rod, the efficiency of drill pipe screwing on and off is improved.The development of this drilling rig has broken the monopoly of foreign products in Chinese market.
