Pedrail:steel pedrail self propelled design, wire driven travel, strong
moving and site shifting ability.
Engine system:The engine system includes engine, water radiator, air filter, and
muffler, and so on. It is the power source of the whole machine.
The engine is CHONGQING Cummins KTA19 turbocharged diesel engine,
large power margin, assuring enough drilling power and also meet
with emergency demand. Powerful and strong, the rated power of the
engine is 392kW/2100rpm, the Max. Back pulling force is 1000kN, the
torque is 55000Nm. economical and oil saving, equipped with suction
water radiator, assuring long time working.
Powered head:The power head is the main mechanism of the drill, adopting low
speed high torque hydraulic motor driving, and then driving the
power head output shaft, high transmission efficiency, compact, it
has high and low double speed stepless regulating function, suits
with different construction requirements. The floating power head
has damping device, which efficiently protect the drill pipe
thread. It has the follow main functions:
1. Driving the drill pipe head slewing
2. Enduring drilling and back pulling reaction
3. The mud passage entering into the drill pipe.
Pull push device of the power head:Pull push device of the power head is the mechanism performing the
power head back pulling and thrusting movement, which provide the
thrusting force and back pulling force to the power head through
Plunger motor, reducer, gear wheel and rack transmission, high
strength and running stably and durably.
The drill pipe frame can slide forward and backward, through angle
adjusting oil cylinder adjust the right drill angle and
Slope-climbing angle to suit different drilling requirements. The
drilling angle adjusting range is: 10°~18°.Two shift stepless speed
regulating, high working efficiency.
Drill pipe assembling/disassembling device:this device consists of onboard crane, drill pipe, landing gear
operating mechanism, and bracket. This device drive the hydraulic
cylinder through hydraulic pressure, assisting with onboard crane,
it can easily assemble and disassemble the drill pipe, reduce the
labor intension, and improve the work efficiency.
Powerful drill pipe clamp (holder):Strong clamping strength, whole-body float, easy angle adjusting
applicable with different long drill pipes. It includes upper clamp
and lower clamp, located in the front of the sliding frame; the
upper clamp has clamp and rotating double actions. The upper and
lower clamps act assorting with the rotation and movement of the
power head to perform tightening and loosening the drill pipe
thread. The drill pipe clamp is driven by motor and moves forwards
and backwards on the drill pipe frame, and the space between front
and rear clamps is adjustable. Equipped with 3.2t auxiliary crane,
fully floating clamp and onboard crane, the drill pipe assembling
and disassembling is high efficient and labor saving.
The anchoring device:the anchoring device is playing anchoring function, located in the
front of the drill; it can raise the whole drill stability.
Mud pump system:can select to equip Lanzhou shengda LT949 skidmounted mud pump, the
mud pump is horizontal single-acting triplex reciprocating piston
pump, it is driven by Chongqing Cummins NTA–855 engine, through
clutch and gearbox driving the mud pump, and connected with the
main machine though high pressure water supplying pipe.
Mud mixing system:Can select 20CBM Mud Agitator
Onboard crane:360°rotating straight arm telescopic jib crane, convenient for
assembling and disassembling the drill pipe and lifting the drill
tools and other drill tools, reduce the labor intensity, improve
the working efficiency.
Monitoring and protection:The monitor has alarm system for up and down interlock, automatic
high pressure protection, engine, hydraulic, filtering etc., which
can efficiently protect the machine under safety condition.
Engine and light alarm: this machine adopts 24V single wire system power supply, minus
earth system. Double 12V storage battery series with the generator
supply the electricity to the whole machine. The machine start
electricity is provided by storage battery, after the machine is
started on, the generator will supply the 24V DC to the whole
machine and also charging the storage battery at the same time.
Press down the STOP knob or emergency switch will let the engine
stop work
Water thermometer: the engine water thermometer is used for indicating the engine
coolant temperature, once the water temperature is over the set
value, the water temperature alarm switch will close, when the
Water temperature warning indicator light, stop the machine and
check.
Oil-pressure gauge: it indicates the oil pressure of the engine. When the oil
pressure is lower than the set value, the oil pressure alarm switch
will close, oil pressure indicator lights,( the light will light
even the engine stopped, it is the normal condition), and stop the
machine and check
Fuel gauge:fuel contents gauge of the engine. If the fuel content is low,
should add more fuel inside
Tachograph: Indicating the current rotating speed.
Engine hour meter:it is indicating the engine working hour’s meter
Voltmeter: indicating the Voltages of Electrical Systems,
Alarm indicator lamps
Oil filter alarm lamp: when the hydraulic filter blocked, the sensor will light, under
this condition u should clear or change the oil filter
Warning light to low oil pressure and high water temperature of
engine:Once the indicator is light,
