ZR220A Rotary Drilling Rig is a high-efficiency hole-forming device launched by Zoomlion following the ZR200 rotary drilling rig. The machine adopts an extendable crawler chassis, self-landing folding mast, retractable drill pipe, hydraulic load sensing control, integrated electronic control and display system, and its engine, hydraulic parts, speed reducer, four-wheel and one-side, electronic control system components, etc. The main components are selected the world's top brands. It is equipped with the logic control of engine power automatic control, hole depth automatic detection, vertical degree automatic leveling, rotary automatic positioning, working status direct display and anti-misoperation. It has the advantages of complete machine stability, large drilling torque, high construction efficiency, flexible maneuverability, multi-functionality, good performance, advanced control and good cost performance.
Performance characteristics:
Cummins QSL-9 supercharged, medium-cooled, electronically controlled engine, 252kW of super power, normal working area above 4500 meters above sea level.
The rope groove design of the hoisting drum is improved, and the life of the steel wire rope is greatly improved.
Power head with heavy shock absorber, can effectively buffer the impact of the drill rod falling.
The unique power head pressure lubrication circuit solves the problem of mutual pressure and oil leakage of the power head pressure oil and hydraulic oil.
The balance valve of the amplitude change cylinder and the ram cylinder has a non-pressure structure, so that the luffing mechanism can move up and down smoothly and the mast can be raised and lowered to prevent a large impact during its movement.
In addition to the automatic idling of the two-stage engine, the drilling rig can be monitored in real time and has multiple alarm functions.
Automatic leveling system of mast verticality, in addition to automatically leveling the mast, and can monitor the landing and landing of the mast.
Strict logic interlock control prevents the driver from misoperation.
Unique hole depth precise measuring device, hole depth error can be controlled at 10cm, drilling accuracy is 1cm.
10.4 inch true color display, high level of man-machine interface, dynamic display of engine speed, fuel consumption and fault diagnosis information, mast verticality, drilling operation status, drilling machine fault diagnosis and other information.
The intelligent fault detection system can dynamically display the status of each actuator of the drilling rig.
