ZDY-LS series full hydraulic crawler tunnel drilling rig for coal mine is suitable for crushed soft coal seam gas extraction drilling. It is mainly used for the construction of multi-layer gas extraction holes, perforation holes, water exploration holes and other purpose holes in this coal seam. Inclination, azimuth, opening height adjustment range is large, high degree of automation; integrated orifice blowout prevention device, can prevent coal and gas ejection, and has the effect of dust collection and dust reduction; can meet the 1.5m drill rod middle plus rod to improve the rod efficiency; embedded automatic anti-power head sliding module to improve the safety of construction ZMJT052ZDY-LS series coal mine full hydraulic crawler tunnel drilling rig features 1, Safety- —Using compressed air as the power source, safe and convenient to use. 2. High power and small size - can walk freely in narrow lanes, easy to move, and reduce the labor intensity of workers. 3. Equipped with two rotating devices, horizontal and vertical - to achieve drilling operations at different heights and angles. 4. Large propulsion force - the drilling rig propulsion mechanism uses an independent motor drive, and cooperates with turbine transmission to improve work efficiency. 02ZDY-750LSZDY-1250LSZDY-2300LS Drilling Depth (m) 150200300 Rod Diameter (m) 42, 505063.5 Drilling Inclination (°) Horizontal 360, Vertical Direction 360 Output Speed (r/min) 105/30080/17070/160 Output Torque (N.m) 750/ 2801250/6002300/1000 feed force (kN) 4060110 lifting force (kN) 304580 normal feed speed (m/min) 0-1.50-1.50-1.5 feed stroke (mm) 850/650850/650850/650 motor power (kw) 18.52237 host external dimensions (mm) 2900*950*16002900*950*16002900*950*1600 Machine weight (kg) about 3800 about 4200 about 4600 walking speed (m/min) 181818 climbing capacity (°) 202020 horizontal horizontal construction height (°) 1.4-1.91.43-1.951.49-2.01 longitudinal level Construction height (°) 0.81-1.330.81-1.330.81-1.34 The working section surface is not less than (width m* height m) 2.5*32.5*30202ZDY-1200LSZDY-1900LSZDY-3200LS drilling depth (m) 200300350 drill pipe diameter (m) 50, 63.563.5, 7363.5, 73 drilling inclination (°) 360 horizontal, 360 vertical output speed (r/min) 80/21090/25090/250 output torque (N.m) 1200/3401900/6803200/1150 feed force (kN) 408080 lifting force (kN) 60110110 normal feed speed (m/ min) 0-1.50-1.50-1.5 to the stroke (mm) 850/650850/650850/650 motor power (kw) 22370245 main body dimensions (mm) 2900*950*16002900*950*950*16002900*1600 overall weight (kg) about 4200 about 4600 4800 walking speed (m/min) 181818 climbing capacity (°) 202020 horizontal horizontal construction height (°) 1.43-1.951.49-2.011.51-2.03 longitudinal horizontal construction height (°) 0.81-1.330.81-1.340.81-1.35 working section surface not less than (width m* height m) 2.5*32.5* 32.5*3
