GQ-15 型工程钻机
GQ-15 ENGINEERING DRILLING MACHINE 1． 钻机适用范围
GQ-15型工程钻机是我厂为大口径基础工程施工所研制的新产品，结构新颖、轻便，可采用正反循环工艺钻进，适应于房屋、高层建筑、堤坝、港口码头、桥梁工程的基础灌注樁孔施工及大口径水井钻进。
2． 钻机主要特点：
◆扭矩大、与同类钻机相比重量较轻，体积也小，因此便于搬迁。
◆采用龙门形结构、动力头上下移动的形式，强度大，刚性好。
◆动力头通孔直径大（182×182mm），既可采用正循环钻进，如配备泵吸反循环设备。也可进行反循环钻进。
◆本钻机强度大，并具有五档正转，一档反转，适用多种地层条件钻进，便于处理孔内事故。
◆动力头配备手动卡盘用四方主动钻杆钻进，回次钻进深度大、效率高。
◆动力头采用油缸直接给进，加压起拔能力大，加减压钻进方便。
◆滑动底座行程为1150mm，让开口范围大，起下钻方便。
◆备有步履机构，钻机移动、对准孔位方便。
◆钻机布局合理，操纵方便、灵活、稳定性好。
◆可配备专用钻塔，使用方便。 1. APPLICATIONS:
GQ-15 engineering drilling machine is newly designed special for large diameter pile hole drilling, can use forward-circulation and reverse circulation drilling methods mainly used in drilling large diameter pile for building, skyscraper, dam, harbor, bridge etc. and drilling large diameter well.
2. FEATURES:
