GYD-20型全液压动力头工程钻机的研制

Development of GYD-20 Drill with Full-hydraulic Dynamic Head

摘要:

针对传统工程钻机生产制造周期长、自动化程度低、劳动强度大、施工效率低等弊端，研制了GYD-20型全液压动力头工程钻机。介绍了该钻机的结构特点及其应用于大口径基础桩孔、煤矿通风孔钻进的情况和效果。

Abstract:

Aiming at the disadvantages of long manufacturing cycle, low degree of automation, high labor intensity and low construction efficiency of traditional drill, GYD-20 drill with full-hydraulic dynamic head is developed. The paper introduces this drill about its structure characteristics and the application effects in large diameter foundation pile hole and mine ventilation hole drilling.
