Description of Rail Mounted Drilling Jumbo DFJ-1R14
1. DFJ-1R14 rail type hydraulic drilling jumbo is mainly used for
tunnel of mining and metallurgy and tunneling project of culvert.
The drilling speed is 0.8-2 meter per minutes. The design of whole
machine is strong. The machine is small and with compact structure,
low center of gravity. The traveling type is rail, which is very
suitable for small tunnel section with rail system.
2. Improve the quality of smooth blasting. Our company design it
ourselves and get a patent for mechanical translation boom which
makes the propulsion beam keep balance in all direction. It can
locate the hole position directly, quickly and accurately. All the
holes are parallel, no need people to correct. It is easy to
operate and can improve the quality of blasting.
3. The oil tank is at high position. It can keep cleanliness of oil
and reduce the risk of hydraulic system failure.
4. The hinge joint of machine breaks through the traditional design
idea that the rail wheel, machine and chassis are whole, which
reduce the turning radius greatly. Two hydraulic motor connects the
rail wheel directly, and control and drive the rail wheel to
realize responsive control.
5. Adopts rotary reducer and spiral swing cylinder to form cross
steering joint, so there is no blind angle in any angles of the
tunnel face, top, side and bottom of the tunnel section.
6. DFJ-1R14 drilling jumbo is equipped with Chinese brand drifter.
It is economical and can drill hole fast. Imported America HELAC
Rotary Actuator with high torque, high bearing, fits, tight spaces,
high anti-pollution, long durability.
7. Adopt drilling control system and manual four direction handle
to control the boom to move translation. It is equipped with anti
jamming function and gradually pressure boost system, which makes
it work more stably, reduce the drilling bits consumption.
8. The design of whole machine is strong. The machine is small and
with compact structure, Low center of gravity, flexible, single
power, low energy consumption, low noise, which can improve working
environment and improve construction efficiency and quality.
