煤矿用全液压履带式坑道钻机

Z DY1250L/ZDY1800L/ZDY2600L煤矿用全液压履带式坑道钻机Full hydraulic crawler-type tunnel drilling rig for coal mining

坑道钻机主要用于煤矿井下钻进瓦斯抽（排）放孔、注浆防灭火孔、煤层注水孔、防突卸亚孔、地质勘探孔及其它工程孔。适用于岩石硬度小于等于1 0的各种煤层、岩层，有三种不同的型号参数的产品。

The rig is used to drill gas extracting (ejecting) hole, grouting method of fire

preventing/extinguishing hole, water injection hole in coal layer, outburst prevention pressure release hole, geology exploratory hole and other engineering holes. It is applicable to coal/rock layer with hardness less than 10.

主要特点Main features

1.液压系统主要采用伊顿进口件，可靠耐用; 桅杆回转采用小回转台回转，可实现正负180

度全方位回转; 采用了铰接支架结构，可实现倾角从负90度到正90度大范围调整; 动力头卡盘采用机械式钻杆接手连接，使连接可靠，减少维修工作量; 夹持器带有自卸扣油缸，使拆卸钻杆更安全高效。

The hydraulic system is imported from Eton, which is reliable and durable. Using small revolving platform for mast to revolve, which can revolve between minus 180 degree to plus 180 degree. With hinge joint support structure, can adjust dip angle between minus 90 degree to plus 90 degree. Adopts mechanical type jackrod as power head chuck, which is more reliable, can reduce maintenance work a lot. There is a self-discharging oil cylinder on holder, which makes the discharge of drill stem safer and more efficient.

2.钻机可独立行走，原地转弯，要求巷道或钻场断面大于6 . 2 5平方米，高度大于2 . 5

米，宽度大于2 . 5米。`

The drilling rig can walk independently, can spot turn, it should work in an environment where fracture surface is not less than 6.25 square meter, height should not be less than 2.5m, and width should not be less than 2.5m.
