为进一步方便XY－44A型岩心钻机进行大倾角及垂直孔钻进，在调研国产系列钻塔的基础上，设计了一种双变幅油缸起塔，带钢索斜拉、天车滑轮平移结构及液压副卷扬的塔机一体钻机。塔架底部与钻机直接相连，顶部装有天车和斜拉钢索架，操作简单、方便，进一步拓宽了立轴式岩心钻机的使用性能，提高了生产效率。

For the convenience of XY-44AT core drill in large inclined angle and vertical drilling, based on the investiga-tion on China-made series derricks, a drill rig erected by double derricking cylinder and cable stayed with translation struc-ture of crane pulley and hydraulic aided hoister was designed.Connected with the derrick bottom and with the crane and steel cable stayed frame on its top, the rig can be simply operated, by which the service performance is further broadened to improve the production efficiency.
