Sino Mechanical's rotary drilling rigs
The main performance parameters of Sino Mechanical rotary drilling rigs are as follows:
(1) Imported electronic injection turbocharged intercooled engine, with extraordinary power and fuel economy, provides a powerful source of power for the whole machine.
(2) Adopting international brand hydraulic components, the system adopts hydraulic pump to adapt to the power limit adjustment control of the engine, minimizes system energy consumption, reduces system heat, and provides a guarantee for the reliable operation of the system.
(3) A special retractable chassis with a hydraulic cylinder and crawler tracks specially designed for rotary drilling is used; the high-performance built-in main and auxiliary winches reduce the tipping torque and rotational inertia force borne by the slewing bearing, improve the stability of construction, and ensure the reliability of the whole machine.
(4) The power head is a dual-motor, dual-speed reduction transmission, which can not only drill with high torque, but also quickly throw soil, with high work efficiency. The 2-source 4-level multi-point circulation forced lubrication and cooling system is adopted to eliminate the oil cross-over phenomenon, and the lubrication and heat dissipation effects are better, ensuring the long-term reliable operation of important components.
(5) After computer optimization design, the structure of the variable amplitude mechanism composed of the boom and tripod is simplified, and the driving force of the drill mast is increased. Regardless of the position of the power head on the drill mast, the horizontal lifting and amplitude change of the drill mast can be achieved. Ensure that the machine has a large working radius and strong adaptability.
(6) Using its own power and structure, it can load and unload itself when the drill mast is in a backward tilted state without a crane, which is convenient for the transfer and transportation of the whole machine. Compared with other models where the drill mast can only be loaded and unloaded when it is in a forward tilted state, its loading and unloading process is safer and more stable.
(7) It has automatic vertical adjustment and depth detection and other operation and fault recording functions. It is equipped with drilling depth and drill mast verticality monitoring, automatic and manual verticality adjustment modes, drill rod height limit, auxiliary winch height limit, working range limit and other limit modes.
(8) The independently developed rotary drilling rigs electronic control system adopts a two-level distributed control structure and applies advanced intelligent control technology, CANBUS technology and virtual instrument technology. It can realize full-range graphic adaptive guidance mast manual control, action interlocking during drilling, and manual or automatic accurate reset of the drill mast after dumping. The system has high integration and automation. It adopts reliable true color LCD screen display monitoring, with friendly human-machine interface, simple operation, safety and reliability.
(9) The side doors of the shed can be flipped up, which has good heat dissipation effect, can expand the operator's field of vision, improve safety, and make maintenance and servicing more convenient.
(10) The humanized design of the cab takes into account the comfort and safety of the driver in every aspect.
(11) The pressurized oil cylinder can realize dual-speed control, and the pressurization and lifting force are large enough and steplessly adjustable.
(12) The wire rope has a long service life, and the average life of each wire rope is more than 3,000 meters.
(13) The friction-resistance and machine-locked drill rods can be used interchangeably, with a maximum drilling depth of 60 meters, and can be equipped with a variety of drilling tools, with a wide range of drilling diameters, and a maximum diameter of 2 meters.
