shall be driven by hydraulic motor. Drill bit shall be mainly driven for
revolution, drilling and back towing and hollow hole of drill collar is the mud
channel to enter into auger stem.
2.4 Drilling rig
As a sliding & supporting device of power head, drilling rig shall slide on the
guide rail by push-pull mechanism of oil cylinder to bear push-pull and
rotation torque of the entire machine.
2.5 (Optional) auxiliary loading/unloading device of auger stem
Auxiliary loading/unloading device of auger stem shall be used to lighten
operator’s intensity and accelerate construction schedu
le.
2.6 Strong auger stem holder
It includes upper and lower jaw vices and it is in the previous part of sliding
support. Upper jaw vice has clamping and rotation motions. Upper and
lower jaw vice will coordinate with motion of power head to screw down or
loosen threads of auger stem. Special buffer device of our company shall
be used to reduce thread abrasion and prolong service life of auger stem.
2.7 (Optional) anchor devices
Ground anchor is used for anchorage of the entire machine. It is located in
the front end to increase stability. It shall be pressurized by oil cylinder for
drilling in/out of anchor rod driven by low-speed and large-torque motor.
2.8 Vehicle-mounted mud system
Large-flow mud pump of 320L/min shall be adopted for vehicle-mounted
mud system. Horizontal reciprocating single-effect piston pump with 3
cylinders shall be used as mud pump which is driven by hydraulic motor to
provide pressure mud for drill.
2.9 Electric system
Electric system of horizontal direction drill mainly consists of engine
monitoring, mud pump control, jaw vice control, high-speed driving control
and high-speed push-pull control of power head, etc.
2.9.1 Engine part and lamp alarm:
DC 24V single-line power shall be adopted for the machine with negative
electrode ground system. Power shall be generated by 2 series storage
batteries of 12V and power generator. Storage battery shall supply power
during vehicle startup and power generator shall supply DC 24V to the
machine power utilization system and charge storage battery at the same
time after operation.
