Ⅰ Configuration of main components
The XZ500 horizontal directional drilling rig is an integral
device. The machine is mainly composed of the chassis, power unit,
and drill stand, engine system, vice, cab, on-board crane,
hydraulic system, electrical system and other components.
1. Chassis
The chassis is mainly composed of the main vehicle frame, left and
right travel devices. The rear end of vehicle frame is fitted with
hydraulic outriggers. The built-in planet speed reducer (with
motor) is used as the travel speed reducer, which has a high output
torque and a compact structure. The wired-controlled travel with
two speeds adopted make it easy and safe to transfer and adjust the
machine among work sites.
2. Engine system
The Cummins 194kW 6-cylinder water-cooled and turbocharged engine
is selected. The max. pulling force is up to 500kN under the torque
of 18000Nm.
3. Power unit
The power unit is driven by motor and speed reducer and its speed
can be adjusted continuously so it is suitable for different work
conditions. The power unit is fitted with damping device so that
the drill stem threads are protected effectively.
4. Pusher and puller
The pusher and puller offers the feeding force or pulling force to
the power unit through the motor, speed reducer and
Rack-and-pinion. This mechanism is strong, reliable and stable. The
drill stand is easy so slide back and forth to adapt to the
drilling angle and gradeability.
5. Potent drill stem holder
It is composed of the upper and lower vices which operate in
accordance with the rotation and movement of power unit to screw up
or off the drill stem threads. Driven by the motor, the holder can
move back and forth on the drill stand, and the distance between
front and rear vices is adjustable.
6. On-board crane
The full-rotating telescopic-boom crane truck adopted facilitates
the lifting, dismounting and mounting of drill stem and can also be
used to lift other drill tools so as to reduce the work load.
7. Cab
The cab is an air-conditioned cab where the operator and direction
controller can work together conformably.
8. Electrical system
It is mainly used to control the functions of rotation, pushing and
pulling, vice and travel, etc, and to monitor the parameters and
protect the engine and hydraulic system. It is composed of the left
console, right console, instrument console and travel control box,
etc.
9. Hydraulic system
The closed circuit control system is used as the power unit
circuit, and the open circuit load sensing control system is used
for drilling and pulling, which can save the energy effectively.
Ⅱ Optional parts for users
1. Drill stem and drill tool
The drill stem produced by Hebei Xuanhua, Wuxi Mineral Exploration
Machinery or other producers can be selected. The cutting-type or
squeezing-type expansion head with a diameter of 250mm~900mm can be
selected.
2. Guide system
The wired or wireless direction control system can be selected.
3. Slurry mixing system
This system is composed of the engine, sewage pump, and slurry tank
and swell soil mixer. The capacity of slurry tank can be 3m3 or 5m3
dependent on the user’s needs.
