Description
The full hydraulic underground drilling rig is applied to the
following fields: coal, metallurgy, geology and engineering, etc.
Specifically, as a kind of underground diamond core rig, it is used
to the large-diameter gas drainage and the water injection hole of
mine, tunnel and coal mine. It is also used to the large-diameter
horizontal drilling of the surface engineering. The full hydraulic
underground drilling rig can accomplish the large-diameter cone
drilling, large-diameter hard-metal drilling and the
percussive-rotary drilling.
Feature
1. The full hydraulic underground drilling rig is split-type
layout. This, along with its light weight, makes its transportation
effortless, its operation flexible.
2. The feeding and rotation function of the unit head is
accomplished like this: the explosion-proof motor and control
system of the power unit puts the hydraulic pump in motion. Thus,
the hydraulic fluid comes into being. By means of the hydraulic
fluid, the motor makes the spindle rotate and multi-speed mechanism
of the hydro-cylinder chain work.
3. The hydraulic chuck can accomplish the clamp and breaking out of
the drilling rod as well as the function of block-out prevention.
4. The mast slide itself. The underground diamond core rig can also
stretch out and draw back. This maintains a close touch between the
mast and the foundation. As a result, the underground drilling rig
will have an enhance stability.
5. The up-and-down swing of both the mast and the swing frame
ensures the drilling from multi angles.
6. The spindle of the unit head has a wide range of rotary speed,
thus a large rotary torque.
