Main Performance Characteristics
1.The structure of the whole machine: the main machine and the power system are integrated structure, compact shape, width 3.5m, height 3.6m, meets the domestic and foreign transportation laws and regulations, convenient for transportation.
2.Three-stage emission electronically-controlled engine meets the national three-stage emission requirements for construction machinery, and it can flexibly realize dual-engine or single-engine work, which saves energy and reduces consumption.
3.Unique design of power head structure:
(1)Gear box front, shorten the diameter change, protect the drill pipe screw, reduce the wear and prolong the life of the drill pipe.
(2) Double-layer structure gear box, finite element stiffness, strength double standard design, gear box strength solid as gold.
(3)Gearbox countersunk design, fully improve the force of the gearbox under the maximum thrust and pull.
(4)Floating design of the main shaft of the power head fully protects the drill pipe screws.
4.Four-point patented clamping technology to improve the rigidity and strength of the structure; compared with the three-point type, there are more cylinders, more contact points and larger area, the clamping force and unloading torque is greatly improved; field maintenance and replacement of the clamping bar is more convenient and quicker; the clamping device can be floated throughout the whole process.
5.Automated rod loading mechanism, Gudeng patented technology, mature and reliable, high degree of automation, freeing up the labor force and reducing labor intensity.
6.Automatic drilling control system, the drilling machine can realize constant torque drilling under the set torque and push/pull force, the computer can control the drilling parameters more accurately and realize the overload protection of the drilling rod; the system pressure and rotary torque can be set steplessly by the electric control system.
7.Humanized intelligent electro-hydraulic joint control and electro-hydraulic monitoring system application:
8.Digital and electronic dual display system double guarantee to ensure the reliable operation of the machine, can monitor the engine operating parameters, system pressure, slewing torque and speed, push and pull force and speed, clamping force, mud pressure and so on.
9.Electro-hydraulic intelligent monitoring and diagnostic system realizes automatic detection and diagnosis of hydraulic system faults, which greatly facilitates the maintenance of the rig at a later stage.
10.Patented Clutch Technology Application， The application of mechanical clutch or hydraulic clutch on the push-pull and slewing system is conducive to the selection of the number of participating motors according to the working conditions, which improves the efficiency of the power system and reduces the construction cost.
11.Slewing, pushing and pulling anti-impact technology, multiple protection of slewing, pushing and pulling motors, resistance to rock and other complex working conditions on the motor impact, improve the reliability and service life of the motor.
12.Industry-leading electric proportional, positive flow hydraulic control system.
13.Using the world's first-class brand of hydraulic components, precise control, improve efficiency, reduce energy consumption, high temperature resistance, anti-pollution.
14.High reliability electrical system, first-class world brand electrical components, integrated line speed design, to ensure the reliability and stability of the electrical system.
