HF-42A Multi-functional Borehole Drilling Rig
Application Scope
The HF-42A core drill rig, integrated rig with tower into one unit, consists of HF-4 drill rig and mast-type drill tower, with the function of hydraulic lifting and lowering of tower. The rig is simple in structure, reasonable in design, light in weight, easy to operate; It is in a wide range adjusting angle. It is especially suitable for drilling of hole with great slope angle.
The tower body of HF-42A Drill Rig is used as lifting drill tools for drilling vertical as well as inclined holes. The range of adjusting angels (in clock-wise direction) for drilling inclined holes is 0° -90° .
Main Components
The drill tower consists of base, tower body, crownblock (pulley mechanism), platform and auxiliary support.
Main Characteristics
The drill tower is pyramid-mast type. Being light in overall weight, single component being light and limited in disassembly quantity, the tower is convenient for transportation and installation. The tower has its own crownblock convenient for ground installation. When the rig is moved back during operation, the tower can be inclined to make up the moved-back distance so as to guarantee the central line between the centers of the hole and pulley. The tower can be adjusted in clock-wise direction for drilling inclined holes. The adjustment is convenient for making and wide in adjusting range. It is suitable for drilling large-angle hole.
I. General
HF-42A Core Drill is a new type high speed diamond core drill, desi9ned according to the development of
Geological work in China and developed to meet the requirements of clients.
HF-42A Core Drill has been identified in 1976, and rewarded with the Chinese National Silver Medal in 1988. The HF-42A model has been sold all over the country.
HF-42A Core Drill can be driven by Deutz F4L 912 diesel engine or 30KW electric motor. The drill has 8 rotary speed stage, the Max, speed 1588 rpm, the min speed 101 rpm, so it is suitable for various drilling for solid mineral deposits with diamond or tungsten-carbide tipped bit.
It is also suitable for engineering geological subterranean water explorations as well as explorations of shallow layer oil and natural gas, and can be used to drill holes for ventilation and drainage of main
Gallery.
II. Main Features
. The rig is in higher rotational speed and rational range of rotational speed; Large torque in low speed.
. The drill is suitable in the mountain area because of light weight for easy transport and convenient disassembly (to be disassembled into nine parts).
. With compact structure and reasonable layout, and all exposed,
Non overlapped components, it is easier for maintenance and repair.
. It is convenient for you to treat trouble with two reverse speeds. With low center of gravity, the rig is reliable and stable in high speed drilling.
. The operation levers are concentrated, so the operations are reliable and convenient.
. Fitted with meters, the circumstances can be controlled easily in hole.
. The transmission is separately driven for drill rig and mud pump; It is easier for the location Arrangement with less space occupying.
