II. Some Technical Advantages of Boom DTH Drill Rig
GPDE series DTH drill rig is new type with integral medium/high air pressure, widely used in field of metallurgy, coal, construction, railway, water&electricity construction, waterway dredging, national defense construction earthworks and other surface engineering blasting hole drilling. It adopts international advanced technology, and featured of following advantages:
1). Integral structure
Drilling machine, compressor and internal combustion power are integrated, it has good maneuverability and can move fast, energy-saving and high-efficient.
2). Independent power module
Air compressing system and hydraulic system are two independent modules, improved the system reliability and guarantee the energy-saving, it has more space to maintenance and repair compared with some foreign brands, and much easier.
3). Convenient and flexible control system
All the control, posture adjustment, drilling hole positioning can be done by "pilot control handle".
The cab is ergonomics designed and with air-conditioner, which greatly improved working condition, all the indicate light and alarm light are installed onto the same board, very easy for the driver to read.
4). Hydraulic servo
It adopted the highly reliable moving mechanism of excavator, with hydraulic leveling mechanism, drilling rotary used hydraulic motor, the lifting of sliding frame adopted hydraulic support cylinder, furthest improved its working efficiency and adaptive ability of cross section.
5). Automatic disassembly
Automatic disassembly mechanism is designed for impactor and drilling rod, including 4 firmly held hydraulic cylinder, which guarantee the drilling rod's effective guiding for trepanning and drilling, ensure the automatic and reliable disassembly, thus lessen worker's burden and improve work efficiency.
6). Reliable damping
Drilling tool rotary mechanism is equipped with hydraulic damping spring, and lengthen the rotary mechanism's working life.
7). Comfortable working environment
The cabin is equipped with air-conditioner and air cleaning facility to prevent outside dust enter into the cabin and thus improve the working environment.
8). Anti-jamming mechanism
The anti-jamming mechanism could effectively protect the equipment when the drilling get stuck.
9). Effective dust cleaning
Vortex and laminar type dust-collecting mechanism could maintain clean working environment.
