38KW 1800rpm Core Drilling Rig , Diamond Core Mobile Drill Rig
XY-4 spindle type core drilling rig is a new drilling rig with high
speed. It is invented to stratify the state-of-art development of
the geological industry and the user's demand. It has been
identified by authority in 1976 and won the national silver medal
XY-4 wireline drilling rig uses Deutz F4L 912 diesel engine or 30Kw
electric motor. It has 8 rotary speed levels with the 1,588rpm at
top and the 101rpm at the bottom. In virtue of its wide seed range,
the drilling rig is suitable for various drilling for solid mineral
deposits by means of diamond or tungsten-carbide tipped bit.
XY-4 wireline drilling rig can be also applied to engineering
geological subterranean water explorations as well as explorations
of shallow oil and natural gas. What's more, it can be used to
drill holes for ventilation and drainage of main gallery, too.
1. The drilling rig has fast rotational speed and broad rotary
2. Thanks to its light weight and easy-disassembly, it can be
easily carried and hence, it is suitable in the mountain area.
3. The core drilling rig has simple structure and reasonable
layout. As a result, its maintenance and repair is effortless.
4. Its gravity center is low. It can move smoothly. This guarantees
its steadies while working at the high speed.
5. Owing to wireline drilling rig's operation lever's
concentration, it is reliable and convenient to operate it.
6. Fitted with meters, the circumstances can be controlled easily
7. The transmission is separately driven for drilling rig and mud
pump; it is easier for the location arrangement with less space

The wireline drilling rig's transmission system consists of
mechanic driving system and hydraulic transmission system. Here
only elucidate driving system in simple works.
The rotation of power unit is driven toward speed change box by
elastic coupling, and then will be change into 4 forward speeds and
1 reverse speed.
The output shaft of speed change box is connect input shaft of
transfer case with universal coupling , then the rotation will be
driven toward hoister or swivel head. By operate the transfer case
speed change level, the swivel head have 8 forward speeds and 2
The oil pump of the wireline drilling rig is driven by V-rubber
belt which is driven by band pulley.
XY-4 Core drill consists of seven basic assembly components:
1. Swivel head assembly
2. Transfer case assembly
3. Hoister assembly
4. Speed change box assembly
5. Hydraulic system
6. Power unit (incl. clutch)
In order to divide and set up conveniently, these components are
joined by connectors such as spline, elastic couplong, universal
The wireline drilling rig is equipped with hydraulic chuck and
lower hand chuck. In the course of normal operating, the lower
chuck is no use, when drilling deep hole or pulling tools out of
the hole, both chucks are used at the same time. On the instrument
board are fitted with drilling pressure gauge, hydraulic systems
pressure gauge and indicating meter. The drilling pressure of the
wireline drilling rig is judged by pressure gauge and the pressure
of which pull rods out of hole, loose hydraulic chuck and make up
or break-out tools and judged by system pressure gauge.
Drill control system
Before operating wireline drilling rig for the first time, it is
essential to have a good knowledge of various control levers'
applications and positions so you will avoid damages. Upon
operating levers, please pay attention to following cases.
1. Before starting drill, you should make sure that all levers are
in right position, such as: at this moment, the clutch lever is in
"off" and every speed change level should be in "neutral position"
2. Speed can be only changed by shifting lever of the speed change
box or the transfer case, after setting the clutch lever to "off"
position and the gear speed is decreasing or stopping.
3. The wireline drilling rig hoister's lifting lever and braking
lever can't be operated at the same time.
4. In the multi-changeover valve block, lever can't be operated at
the same time except lever of the overflow valve's boost pressure.
5. Hoisting and lowering rod by the hoister the hoist and drill
head clutch lever should be in "neutral gear".
