Abstract
The utility model discloses a kind of down-the-hole drilling pipes to improve structure, it is desirable to provide the high down-the-hole drilling pipe of a kind of low noise, with small vibration, less energy consumption, construction efficiency.It includes drilling pipe ontology, the drilling pipe ontology by tube body, be fixed on the tube body one end and male thread connector with airflow channel, be fixed on the tube body other end and constituted with the box thread connector of airflow channel；It is filled with PVC internal lining pipe (4) in tube body (2), the internal diameter of the PVC internal lining pipe is identical as male thread connector airflow channel (6-1) and box thread connector airflow channel (1-2) diameter.It is drilled using the utility model, construction operation efficiency can be improved about 15%, air compressor machine and save that fuel oil is nearly 20%, can reduce noise up to 60% or more；It is a kind of improvement of down-the-hole drilling pipe.
Description
Technical field
The utility model relates to a kind of down-the-hole drilling pipes more particularly to a kind of down-the-hole drilling pipe to improve structure.
Background technique
Down-the-hole drilling pipe is and can be combined extension as needed for connecting down-the-hold drill bit, being provided pressure-air
A kind of hollow drill pipe；Usually it is made of the male thread connector and box thread connector for being respectively welded at tube body both ends.For the ease of
Deslagging and mitigation weight, now widely used down-the-hole drilling pipe tube body generally use large diameter thin wall hollow steel tube structure；Although
Be able to satisfy the requirement of down-the-hole drilling tool, but there are noises it is big, fracture protection is insufficient, energy consumption is high the problems such as, it would be highly desirable to improve.
Summary of the invention
In view of the above defects of the prior art, the utility model is intended to provide a kind of low noise, with small vibration, energy consumption
Less, the high down-the-hole drilling pipe of construction efficiency improves structure.
To achieve the goals above, the utility model uses following technical scheme: it includes drilling pipe ontology, the drilling pipe ontology
By tube body, it is fixed on the tube body one end and male thread connector with airflow channel, is fixed on the tube body other end and with gas
The box thread connector of circulation road is constituted；PVC internal lining pipe is filled in tube body, the internal diameter and male thread connector gas of the PVC internal lining pipe
Circulation road and box thread connector airflow channel diameter are identical.
Flexible filled layer between PVC internal lining pipe and tube body；The flexibility filled layer is by several sealing rings or by being wrapped in
Sponge or fiber in PVC liner pipe outer wall are constituted.
Compared with the prior art, the utility model on the basis of traditional structure by adopting the above-described technical solution, increase
Add PVC internal lining pipe, there is an advantage in that:
1) since PVC liner bore is identical as the airflow channel diameter of male and female nipple, it is thus eliminated that air-flow is logical
The case where road cross-sectional area mutates；It can effectively avoid high pressure draught and pass through the impacting with high pressure that generates when the mutation cross section
Sound wave and therefrom caused vibration.
2) PVC internal lining pipe has good sound-absorbing effect, can further decrease high pressure draught friction and the noise that generates；
3) soft using being made of rubber seal or sponge or fiber etc. between PVC internal lining pipe and inboard wall of tube body
Property filled layer, PVC internal lining pipe can be not only fixed, prevent it from frequently shaking in tubular body, colliding and generate vibration and
Damage, but also be avoided that and cause noise therefrom；The partial noise that high pressure draught is generated by friction can be also absorbed simultaneously, into
One step vibration damping, noise reduction.
4) PVC internal lining pipe can fill the segment space of tube body, so that high pressure gas needs after increasing drilling pipe every time
The idle space to be filled becomes smaller, shortens the air-flow filling time, has not only improved efficiency but also has reduced energy consumption.
5) when tube body is broken, since PVC internal lining pipe has high-tenacity, tube body can't be separated into two sections at once；For
Processing fracture accident has won valuable buffer time, has a safety feature.
It is demonstrated experimentally that being drilled using the utility model, construction operation efficiency can be improved about 15%, air compressor machine and save combustion
Oil nearly 20% reduces noise up to 60% or more, and construction environment noise pollution is obviously improved.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model embodiment.
In figure: box thread connector 1, box thread connector airflow channel 1-2, tube body 2, sealing ring 3, PVC internal lining pipe 4, sponge
Or fiber 5, male thread connector 6, male thread connector airflow channel 6-1.
Specific embodiment
The utility model is described in further detail with specific embodiment with reference to the accompanying drawing.
As shown in Figure 1: drilling pipe ontology by steel tube body 2, the box thread connector 1 that is welded in the tube body left end, be welded in this
The male thread connector 6 of the another right end of tube body is constituted, and the inside of box thread connector 1 has box thread connector airflow channel 1-2, male thread
The inside of connector 6 has male thread connector airflow channel 6-1.The matched PVC internal lining pipe 4 of length is filled in tube body 2,
The internal diameter of the PVC internal lining pipe is identical as male thread connector airflow channel 6-1 and box thread connector airflow channel 1-2 diameter.
In order to which PVC internal lining pipe 4 is fixed, flexible filled layer between VC internal lining pipe 4 and tube body 2.Flexibility filling
Layer can be made of several sealing rings 3, can also be made of the sponge being wrapped on 4 outer wall of PVC internal lining pipe or fiber 5.
Claims (4)
