200m Deep Hole Hydraulic Drilling Rig For Coal Mine Crawler
Hydraulic Core Rig
1. Brief introduction of JDL-280 mechanical top drive core drilling
rig
JDL-280 drilling rig is a mechanical top drive drilling equipment
integrating water drilling and air drilling, which solves the
difficulty of drilling with air DTH hammer for soil gas drilling,
and drilling in hard rock, gravel, and pebble layers with water
drilling mud Due to the problem of low construction efficiency,
water and gas dual-purpose drilling rigs are suitable for various
formations, and the drilling efficiency of well drilling and
geological exploration is high.
2. Features of JDL-280 mechanical top drive core drilling rig
(1)Equipped with a rubber steel wire crawler chassis, strong
off-road capability without damaging the road surface;
(2)Equipped with 4 hydraulic high outriggers, which is convenient
for on-site leveling and can automatically load and unload trucks,
saving costs;
(3)The drilling rig is equipped with a drill rod frame, and the
design is humanized;
(4)The front end of the drilling rig is equipped with an auxiliary
rod unloading cylinder, which is convenient for loosening the drill
rod;
(5)The hydraulic oil pump and the power are directly connected with
a cardan shaft, which makes the climbing and moving of the drilling
rig more powerful;
(6)It adopts automobile gearbox and hydraulic release bearing,
which has high feasibility and easy and convenient gear shifting;
