Product Description Product DescriptionThe 800 meter rope core drilling rig adopts an inner and outer tube separation design, which quickly extracts rock cores through steel wire ropes without the need for frequent disassembly of drill rods, greatly improving drilling efficiency. Its working principle is: during drilling, the outer pipe connects to the drill rod to transmit torque and pressure, driving the diamond drill bit to break the rock layer; The inner tube independently accommodates the rock core. When the rock core is filled, the ground operator lowers the salvager through a winch and uses a wire rope hook to hang the top salvaging head of the inner tube, lifting the inner tube and rock core as a whole to the surface. At the same time, the outer tube and drill rod remain in place to continue drilling. During the drilling process, the mud or air circulation system continuously cools the drill bit, carries rock debris, and stabilizes the wellbore. The intelligent control system monitors real-time parameters such as drilling pressure, speed, and flushing fluid flow rate to automatically optimize drilling parameters. This technology reduces the number of drilling operations by 90% and achieves a core recovery rate of up to 98%. Combined with modular drill rods and high-strength tower structures, it can adapt to complex geological conditions ranging from hard rocks to fractured formations. It is widely used in mineral exploration, scientific drilling, and engineering geological surveys, achieving efficient and accurate deep hole core extraction.ModelRL400RL600RL800RL1000RL1500EngineyuchaiyuchaiyuchaiWeichaiWeichaiControl boxSingleSingleDoubleDoubleDoubleLifting force12T16T20T25T30T+Drill head stroke3.6m3.6m3.6m3.6m3.6mTurning torque400-800Nm600-1200Nm800-1400Nm1000-3500Nm2500-5500NmRotation speed1300r/min1300r/min1300r/min1300r/min1300r/minDiameter76-12276-12276-12276-12276-122Rod length1.5m1.5M1.5M1.5m3mRod diameter76/8976/89/9676/89/9676/89/96/12276/89/96/122Leg1.5m1.5m1.5m1.5m1.5mMud pump90--3mud pump90-3mud pump160mud pump250mud pump320mud pumpUphill angle45°45°45°45°45°Moving speed2.5/h2.5/2.5/h2.5/h2.5/hDimensions4.1*1.7*2.25M4.1*1.7*2.25M1.4*1.7*2.25M4.5*1.8*2.6M6.0*2.0*2.6MWeight3.5T+3.8T+7.5T+7.5T+8.2+ Our Advantage1. Full hydraulic control is convenient and flexibleIt can adjust the speed, torque, propulsion axial pressure, anti-axial pressure, propulsion speed, lifting speed of the drilling rig at any time, as well as the stylized experience value rig parameter matching program. To meet the needs of different drilling tool operating conditions and different construction technologies. 2. Top drive rotary propulsion liftTop drive power head has anti-impact design patented technology, rotary gear reducer reliable and durable, direct access to the drill pipe, shorten the auxiliary time, but also conducive to pipe drilling. 3. Multifunctional drillingVarious drilling processes can be used on this drilling rig, such as: down-the-hole drilling, through-air reverse circulation drilling, gas lift reverse circulation drilling, cutting drilling, roller cone drilling, heel drilling and core drilling, etc. The drilling rig can be equipped with mud pumps, foam pumps, generators or sampling equipment according to user requests. The drilling rig also comes standard with various winches. 5. High work efficiencyAll kinds of centering devices, rod feeding mechanisms, rod unloaders, lifters, anti-sludge one-way check valves, centralizers, low-temperature start-ups, specialized air filters, etc., are suitable for various drilling processes and the requirements of different use environments. They are easy to control and flexible, with fast drilling speed and short auxiliary time. Therefore, the operation efficiency is high and the risk of construction accidents is reduced. 6. High outright crawlerThe high outriggers are easy to load and transport, and can be loaded directly without a crane. Tracked walking is more suitable for muddy on-site movement. 7. Unique Adjustment of Positive and Negative Axial Pressure for Full Hydraulic Drilling RigAll kinds of impactors want to achieve higher impact efficiency have their matching better axial pressure and speed. During the drilling process, with the increasing number of drill pipes, the axial pressure on the impactor is also increasing. Therefore, during construction, the positive and negative axial pressure valves are adjusted to ensure that the impactor can obtain a more matching axial pressure. At this time, the impact efficiency is higher. 8. Efficient and durable oil mist dispensers and pumpsDuring the drilling process, the high-speed impactor is lubricated at all times to extend its service life to the greatest extent.About UsLocated in Mengyin County, Linyi City, Shandong Province, Shandong Runli Mining Machinery Co., Ltd. is a large-scale manufacturing enterprise specializing in the research, production, and sales of exploration and drilling machinery equipment.
