Rotary drilling machine of the rock drill guide rock drill guide rotary drilling machine YGZ70 rail independent rotary rock drill is a compressed air-powered drilling equipment, Drill Rig or umbrella drilling hanger supporting role, mainly used for roadway excavation drilling level or down blast hole drilling diameter Φ38-Φ55 mm, effective drilling depth of eight meters, drilling can be reversing. Can also be used in railway, road transport, infrastructure, water conservancy and quarrying projects drilling construction. Main Technical Parameters: Weight 70kg Dimension (LWH) 800 × 230 × 210mm air pressure 0.63MPa role of water pressure the the 0.45MPa impact can be ≥ 112J impact frequency ≥ 43Hz idle speed ≥ ≥ 300r/min maximum torque of 85Nm air consumption ≤ 159L / S hole diameter Φ38-55mm drilling depth of 8m 25 × 159mm Shank specifications detailed purpose and scope: the purpose and scope of use YGZ70 rail independent rotary rock drill Drill car, CTJ3 type approach, CNJ -3 type internal combustion drill rig and SJZ series umbrella drilling hanger supporting, mainly for roadway excavation drilling horizontally or to blast holes in railway, water conservancy and national defense construction projects for drilling operations matching with the corresponding equipment and can drill up to blast holes. The machine is suitable for various ore and rock drilling Φ38 - Φ55 mm cannon hole, the effective pore depth of 8 m. The solder can be rotating, and it applies to the drilling of the extension bar. To the Technical Specifications Dimensions (L × W × H) 800 × 230 × 210 mm Machine weight 70 kg cylinder diameter of 110 mm piston stroke of 45 mm piston weight of 3.7 kg acceptance pressure in the 0.63Mpa when impact energy ≥ 112J drilling impact frequency 43 ≥ Hz idling speed ≥ 300r/min torque the ≥ 85Nm air consumption ≤ 159L / S Hose impact part of the 32 mm switch to solder some 19 mm water pipe inner diameter of 13 mm hole diameter of 38 to 55 mm drilling depth 8m solder tail specifications hexagonal 25 × 159 mm, the structural characteristics of YGZ70 drilling machine using impact and transfer solder separate structure (see Figure 11), the impact energy and the drill rod speed were adjusted according to the rock conditions. Impact part of the valveless gas distribution. Start using resistive tail plug part, the gas pressure by blocking the end of the hole to promote stem forward to extend and improve the sensitivity of the machine to start. Turn the solder part of the gear wind motor-driven rotary drill rod is driven by three gear reducer. A wind motor gear sets a two-shaft structure outside of the rock drill piston, gear reducer. The rock drill is compact, small size, attractive appearance, the center of the drill rod to the top from the small (80 mm), more suitable for tunneling operations to drill to help eye. Shank hex 25 x 159 mm, an increase of solder tail and solder sets the contact area, to improve the life of solder tail and solder sets. , Use and maintain (a) YGZ70 rock drill, turn brazed torque, the number of high impact, due to independently impact and rotation can be adjusted separately structure, it is adaptable to a variety of rock drilling when Brazing is not easy card. The proper use of reasonable adjustment, can obtain a higher drilling speed in a variety of rock. Operating essentials: 1. Rocks of different lithologies, under a row of powder were adjusted impact energy, turn brazing speed and thrust, in order to obtain a higher drilling speed. Such as hard or soft rock, impact energy transfer brazing speed can be higher, the thrust should not be too large, in the face of hard rock, the impact energy will have to turn the brazing speed should be low, the thrust should be more . In the case of cracks, caves card brazing, will have to reduce the impact energy, increase the speed of transfer solder can even stop the impact, totally dependent on the rotation troubleshooting card brazing. (3) the impact part of the wind did not start, the control valve should be closed, re-start after the discharge of the residual gas to be duct. (4) avoid a full wind open empty. (5) rock drill lubrication conditions should be good research injury to prevent grinding (especially the piston and the cylinder and with gas with the surface) in the high-speed movement, resulting in local temperature. Lubricant selection of drilling oil (refinery products). Also available on the 20th oil and calcium-based butter. The lubricant should maintain a continuous supply, generally use the oiler can adjust the amount of oil, fuel supply should be appropriate, too much is caused by oil mist, too small to poor lubrication. (6) drill should meet the quality requirements. (B) maintenance of a rock drill, the need for regular maintenance, repair or replace the damaged parts, so as not to cause damage to the other parts. 2 in each class before the operations, should first fill up of the oiler, carefully check all the fastening bolts, to ensure the reliability of the connection, and then give the rock drill to the small amount of wind, the air operation, check the machine is functioning properly, so that each machine at the same time pieces to get lubrication. 3 after the shut down valve, rock drill a small amount of wind for a short time air operation, eliminate stagnant water to prevent corrosion. (4) drilling machine a long time to stop using
