YDL-300DX full hydraulic multi-function drilling rig is a new type of
high-efficiency, energy-saving and multi-functional full-hydraulic drive
and power head multi-purpose drilling rig. It is mainly used for
construction work in tunnels, tunnels and subways. It is also suitable
for drilling drilling wells, monitoring wells, geothermal
air-conditioning hole construction, national defense engineering,
anti-floating anchors, cable-stayed anchors, high-pressure rotary
jetting, etc.; it is also suitable for hydropower projects, railways,
highways, urban foundations, etc. Large-aperture vertical hole
construction in soil engineering; grouting reinforcement hole; small
pile hole; micro pile. The rig can be equipped with a variety of
processes, such as pneumatic down-the-hole hammer drilling, air foam
drilling, gas lift reverse circulation drilling, long auger drilling,
mud circulation drilling, eccentric heel drilling, and drilling. Wheel
bit drilling, hydraulic hammer drilling, etc.
The rig is equipped
with a high-torque hydraulic motor for rotation, cylinder advancement
and lifting capacity. It is equipped with hydraulic tools to hoist and
reduce labor intensity. The power head has multiple speeds to make the
borehole wider.
Main feature:
1. The drilling rig has
strong drilling ability, wide application range, fast drilling speed,
strong ability to handle accidents and high drilling efficiency.
2.
The power head of the rig can be mechanically and hydraulically
double-shifted. Suitable for a variety of drilling methods such as
down-the-hole hammer, heel pipe, full casing and alloy rotation.
3.
Two large oil cylinders on the mast have a lifting force of 25 tons. The
eccentric can be used for drawing the casing when drilling, and it can
also be used for small non-excavation construction.
4. The rig adopts
internal and external telescopic masts. In order to be applied to
tunnels, tunnels and subway construction, the power head stroke is
shortened to 1.7 meters, and one drill can be used for 1.5-meter drill
pipe operation.
5. The main shaft adopts a telescopic buffer
mechanism, which can effectively protect the drilling tool, and at the
same time protect the drill pipe thread from being damaged when the
shackle is shackled.
6. The drilling machine is equipped with a
hydraulic clamping shackle (ф60-ф219) on the orifice device, which
automatically reduces the auxiliary time and reduces the labor
intensity. The orifice is equipped with guiding devices to make the
drilling more stable and reliable.
7. The rig is loaded on the
crawler chassis to make the whole machine shift and the walking is
faster and more convenient. Users can choose iron track or engineering
rubber track, engineering rubber track does not hurt the ground, but
also can work in the city.
8. The main components of the hydraulic
system of the drilling rig are made of famous products at home and
abroad, which makes the performance of the whole machine stable and
reliable and has a long service life.
9. The drilling rig can be
applied to a variety of drilling methods: air DTH hammer drilling, mud
circulation full casing drilling, air DTH hammer and pipe drilling,
roller bit drilling, high pressure spinning operation, etc.
10. The
mast is equipped with tool hoisting (1.5 ton lifting force), which is
convenient for lifting the drill pipe and other tools.
11. The drilling rig has a high-position rotating platform, which makes the drilling machine more flexible during construction.
12. The user can select the motor or diesel engine as the power of the rig.
13, the user can customize the telescopic mast of various strokes according to their own needs.
