Secret Teach you how to distinguish the drill. Name of
drilling rig and trolley? _ Impact

Originally published as Secrets Teach you how to
distinguish the drill Name of drilling rig and trolley In
the following the professional terms that are easy to be
confused in the rock drilling machinery commonly used in
several mainstream mechanical drilling methods are sorted
out the terms such as top hammer impact drilling down-
the-hole drill power head trolley and drill carriage are
explained and explained and the names of commonly used
drilling equipment are standardized and sorted out which
is conducive to the exchange of business and technology
in the industry 01 Necessity of product name
identification In the industry of earthwork engineering
tunnel engineering and mining machinery the names of
"drill rig" "drill carriage" and "trolley" often appear
For down-the-hole equipment
dth rock bit
most people call it "drill rig" and some people call it
"drill carriage"; Top hammer type rock drilling equipment
which is called "rock drilling jumbo" "drilling rig" and
"drilling rig" by some people has no uniform and
standardized name The confusion in the use of product
names is not conducive to the statistical management of
social commodities to the exchange of technology and
business and to the search of search engine nouns
Confucius said "If the name is not correct the words will
not be correct and if the words are not correct the work
will not be done" "Name rectification" is the need of
social communication and the inevitable trend of social
development In this paper the meaning and use scope of
"drilling rig" "drilling rig" and "trolley" are discussed
for the reference of producers sellers users and industry
managers Readers are welcome to discuss and correct the
inappropriate points so as to gradually standardize the
names of products so that each type of drilling machinery
products has only one formal written name Expand the full
text 02 Drilling principle 21

Percussive drilling principle The percussive principle is
applicable to the drilling of medium-hard and above rocks
The equipment for drilling by percussive method includes
pneumatic rock drill hydraulic rock drill down-the-hole
drill steel cable percussive drill etc Percussion
drilling can be divided into two types down-the-hole
drilling and top-hammer drilling 211 Principle of down-
the-hole drilling The principle of down-the-hole impact
drilling is shown in Figure 1 The down-the-hole drilling
is to install the impactor with impact effect at the
bottom of the drill pipe and directly impact the drill
bit to drill the hole 212 Principle of top-hammer
percussion drilling The principle of top hammer impact
drilling is shown in Figure 2 Top hammer drilling is a
way of drilling by installing the rock drill with impact
effect on the top of the drill rod directly impacting the
drill rod and transmitting the impact energy to the drill
bit through the drill rod 22 Cutting drilling principle
The cutting drilling principle is shown in Figure 3 The
cutting principle is applicable to drilling in soil or
soft rock The equipment for drilling by cutting method
includes cutting drilling rig rotary drilling rig coal
power station coal mine roof bolter etc Because the
cutting action is produced primarily by rotational torque
it is also referred to as rotary cut drilling 23
Principle of rolling and drilling The rolling principle
is applicable to the drilling of rocks below medium
hardness The roller drill applies the rolling principle
to the drilling The drilling process of the roller bit is
shown in Figure 4 The drill is connected to the roller
cone bit through the drill rod and the drill rod is used
to pressurize the bit into contact with
dth drilling
hammer the rock At the same time under the
rotating action of the drill pipe the cone with column
teeth on the drill bit rolls and through the column teeth
in contact with the rock the vibration impact and press-
in force are transmitted to break the rock This kind of
drilling method is a combination of vibration impact
crushing action and shear crushing action so it is called
rolling drilling because the cone rolls on the rock it
can also be called rolling drilling Coal mine roadheaders
and tunnel boring machines all use the principle of
rolling and crushing rocks 24 Vibrating drilling
principle The principle of vibration drilling is shown in
Figure 5 Vibration drilling is applicable to drilling in
soil or soft rock The equipment for vibration drilling
includes sonic drill ultrasonic rock drill etc 25
Combined action of multiple principles Percussive cutting
rolling and vibrating methods are the four basic ways to
drill holes in rock or soil Actual drilling equipment is
generally a combination of several principles For example
hydraulic rock drill drilling is mainly based on impact
action supplemented by cutting action Sonic drilling is
based on the principle of vibration and the combined
action of vibration rotary cutting and rolling

03 Difference between drilling perforation and rock
drilling 31 Drilling Whether it is earthwork tunnel
engineering or mine excavation engineering; whether it is
impact cutting or vibration as long as it is a drilling
operation it can be called drilling 32 Perforation In
rock excavation operations in open pit and underground
mines boreholes may also be referred to as perforations
33 Rock drilling Percussion drilling and percussion-based
drilling operations can be called rock drilling Equipment
using other drilling principles such as cutting and
vibrating drilling operations cannot be called rock
drilling 04 Definition of down-the-hole hammer rock drill
and power head 4 mining
dth bit 1 Definition of down-the-hole impactor As
the name implies the down-the-hole impactor is a tool
that uses the principle of down-the-hole impaction to
drill holes Down-the-hole impactor is called impactor
English "Down The Hole Hammer" " so it is also called
down-the-hole hammer GB/T 6247 defines the down-the-hole
impactor as "a tool installed at the front end of the
drill rod and diving into the bottom of the hole for rock
drilling" which is completely accurate 42 Definition of
rock drill A drill that uses the principle of top hammer
impact to drill holes is called a rock drill Rock drill
is divided into pneumatic rock drill and hydraulic rock
drill; it can also be divided into hand-held rock drill
outrigger rock drill guide rail rock drill and so on
GB/T6247 defines the rock drill as "a machine with
percussive and slewing mechanism for drilling and
drilling" which is generally correct but the following
three points are questionable (1) It should not be called
a machine but an appliance or a tool because the
structure of the rock drill is relatively simple there is
no power part and it needs to input hydraulic power or
pneumatic power from the outside (2) Emphasis should be
placed on the impact action as the main and the rotary
cutting action as the supplement Machines and tools with
rotary cutting as the main part and impact as the
auxiliary part are generally called power heads not rock
drills (3) It is not pointed out that the rock drill can
only be used for top-hammer drilling Although the down-
the-hole impactor is a percussive drill it cannot be
called a rock drill 43 Definition of power head The
machine with output torque and rotating speed is called
power head The volume weight output torque and power of
the power head are far greater than those of the rock
drill The power head is generally used for the drilling
operation of rotary drilling rig pipe shed drilling rig
and anchor drilling rig 05 Definition of drilling rig
drill rig and jumbo 51 Definition of drilling rig The
connotation of drilling rig is the most extensive which
generally refers to all drilling equipment Any equipment
that can drill a hole in soil or rock can be called a
drilling rig whether it is percussive cutting rolling
vibrating or combined drilling or mobile drilling
equipment and fixed drilling equipment such as oil
drilling rigs geological coring rigs etc GB/T6247 defines
the drilling rig as "a machine that mainly relies on the
slewing mechanism to drill rock holes" which greatly
narrows the connotation of the drilling rig thus
excluding the down-the-hole percussive and top-hammer
percussive drilling equipment from the drilling rig This
is inconsistent with the actual situation in our country
Most manufacturers and users in our country call the
down-the-hole percussive drilling equipment as down-the-
hole drill Zhangjiakou Xuanhua the famous "hometown of
drilling rigs" in China mainly produces down-the-hole
percussion drilling rigs It is suggested to be revised
when GB/T6247 is revised 52 Definition of drill jumbo
Drill carriage is defined in GB/T6247 as "a carriage for
rock drills to drill rock holes" According to this
definition only the rock drilling vehicle using top
hammer percussive drilling can be called a drilling
vehicle and the down-the-hole drilling equipment can not
be called a down-the-hole drilling vehicle There is a
contradiction between this and GB/T1590 In the category
of drilling rig GB/T1590 includes many product names such
as open-air down-the-hole drilling rig open-air medium-
pressure down-the-hole drilling rig open-air high-
pressure down-the-hole drill rig and open-air hydraulic
down-the-hole drill rig In English words such as "drill
rig" "and" drill Jumbo "" indicate drilling equipment
without the meaning of "vehicle" while words such as
"vehicle" "car" and "truck" indicate vehicles In the
world there are few reports about using "vehicle" to
describe self-propelled drilling equipment "Rig" has the
meaning of "drilling rig drilling frame drilling tower
platform" and generally refers to all drilling rigs in
English

"Jumbo" has the meaning of "giant" Compared with hand-
held rock drills and outrigger rock drills single-arm
double-arm and three-arm rock drilling jumbos are of
course giant so "Jumbo" can be translated as rock
drilling jumbo The original meaning of "wagon" is "four-
wheeled carriage" which also refers to a train or a
carriage of a train Later wagon evolved into a substitute
name for a car model In the current English materials of
foreign drilling rig companies it is almost impossible to
use "wagon" to refer to a drilling rig It is suggested
that the self-propelled drilling equipment with faster
running speed should be called drilling rig for example
the drilling rig that is converted from a car can be
called drilling rig 53 Definition of rock drilling jumbo
Underground top hammer impact rock drilling equipment is
called rock drilling jumbo Underground construction
equipment also includes anchor bolt jumbo concrete
spraying jumbo and prying jumbo etc which are called
jumbos for short The drilling jumbo has the narrowest
connotation only the underground top hammer impact
drilling equipment Underground top hammer impact rock
drilling equipment can be subdivided into tunnel driving
jumbo roadway driving jumbo mining jumbo and so on
Although "jumbo" also contains the word "car" it
emphasizes the word "platform" On this platform one or
two or three or more drilling booms can be installed for
drilling operation The content of GB/T6247 does not
include "rock drilling jumbo" In fact the term "rock
drilling jumbo" is widely used It is particularly common
in railway tunnel excavation and underground mining
engineering and has been established by usage It is
suggested that the drilling jumbo should be defined when
the standard is revised in the future Open-air top hammer
impact drilling equipment is generally called drilling
rig not rock drilling jumbo which is also established by
usage 06 Sum up The names of commonly used drilling
equipment are arranged as follows (1) Fixed drilling
equipment can only be called drilling rig; (2) The
drilling equipment using the roller bit can only be
called a roller drill; (3) Rotary cutting drilling
equipment shall be called drilling rig such as cutting
drilling rig and rotary drilling rig; (4) Equipment using
power head for drilling shall be called drilling rig such
as pipe shed drilling rig and top drive drilling rig; (5)
Down-the-hole percussive drilling equipment should be
called down-the-hole drill; (6) Open-air top hammer
percussive drilling equipment should be called open-air
top hammer drilling rig; (7) Tunnel and underground top
hammer percussive drilling equipment should be called
rock drilling jumbo; (8) Drilling equipment modified from
automobiles should be called drilling rig; (9) If the
traveling speed is very slow such as less than 10KM/H it
should be called a drilling rig Thank you for reading
