Abstract
The utility model provides a drill rod for a coal mine. The drill rod comprises a drill rod body; a sleeve pipe is arranged at the periphery of the drill rod body; the sleeve pipe and the drill rod body are fixedly connected through members; and the sleeve pipe is provided with slag discharging incisions. The drill rod is simple in structure and easy to manufacture; the sleeve pipe is arranged at the periphery of the drill rod to ensure that the drill rod body is easy to position, and a drill bit is prevented from being deflected; the outer surface of the sleeve pipe is polished, so that the friction is reduced, and the drilling efficiency is improved; and the outer surface of the sleeve pipe is provided with the slag discharging incisions, so that the frictional resistance of crushed rock particles to the drill rod can be eliminated.
Description
Technical field
The utility model relates to safety of coal mines equipment, relate in particular to a kind of colliery be used to prevent and treat coal and the outstanding boring of gas with gas pumping, prevent harnessing the river, construction drilling rod that geological survey is holed.
Background technology
Coal mine gas is claimed coal bed gas again, is the hydrocarbon gas that is stored in the coal seam, and Main Ingredients and Appearance is a methane, is inflammable and explosive gas, and Safety of Coal Mine Production is had great threat.Mostly the colliery of China's most of areas is coal and gas outburst mine; Coal mining enterprise, projecting mine to projecting mine should be according to the actual state and the conditions of projecting mine; Formulate regional complex outburst prevention measures and local comprehensive outburst control measure, wherein regional protrusion-dispelling boring is main outburst prevention measures.
The down-hole receives the influence of aspects such as drilling equipment, geological conditions, boring lithology and manual operation in the boring of construction area protrusion-dispelling, boring off-design track occurs through regular meeting, forms protrusion-dispelling control blind area, has greatly outstanding hidden danger.Drilling rod be will with could use after drill bit is fixedly connected; Existing drilling tool is because the diameter of drill bit is bigger and relatively heavier than drilling rod; Using receives to conduct oneself with dignity influences situation such as causing drilling tool is sagging, hole deviation, causes the interior deslagging of boring not smooth in the practice of construction process, is unfavorable for drilling construction.
In addition, be used on the colliery gas pumping, anti-harness the river, the drilling rod of drilling construction such as geological survey also same problem can occur.
The utility model content
The utility model is exactly in order to overcome the above problems, and provides a kind of colliery of accurate extinction of boring to use drilling rod, reaches to solve the hole scattering problem, makes boring keep the purpose of design straight path operation.
In order to achieve the above object, the utility model provides a kind of colliery to use drilling rod, comprises the drilling rod body, and said drilling rod body periphery is provided with sleeve pipe, and said sleeve pipe is fixedly connected through member with the drilling rod body; Said sleeve pipe is provided with the deslagging otch.
The prioritization scheme of such scheme is, said sleeve pipe and drilling rod body are fixing through the member welding, and sleeve pipe is the steel round tube.
The prioritization scheme of such scheme is to be respectively equipped with two deslagging otch of vertically arranging on the said sleeve pipe periphery halves line.
The prioritization scheme of such scheme is that said deslagging otch is wide 2～5cm, the rectangle of long 20～40cm.
Add circular steel sleeve pipe in drilling rod body periphery, sleeve pipe adopts the member of special substance to be fixedly connected through welding manner with the drilling rod body, and the external surface of sleeve pipe adopts special process to polish smooth, and makes sleeve pipe resistance in rotary course keep minimum.When holing, hole with drill bit in the place of regulation, the sleeve pipe of drilling rod body outside is located, and prevents that drill bit from producing skew.Drilling rod is when the boring rotation; Ground grains gets in the gap between drilling-rod external wall and the sleeve pipe; Then can discharge from the deslagging otch, the deslagging otch vertically is symmetrically set on the sleeve pipe periphery halves line, has four; Discharged foreign material such as rubble, dust well, eliminated the frictional resistance of fractured rock particle drilling rod.So the utility model solves the hole scattering problem, letting boring keep the operation of design straight path, realize protrusion-dispelling, guarantee that the mine outburst prevention measures implements completely, ensure Safety of Coal Mine Production.
So the utility model is compared with prior art has following beneficial effect:
1, the utility model simple in structure, be easy to make;
2, establish sleeve pipe in drilling rod body periphery, make drilling rod be prone to the location, and prevent that drill bit from producing skew; Bushing outer surface has carried out polishing to be handled, and has reduced frictional force, accelerates drilling efficiency;
3, bushing outer surface vertically is arranged with slag-drip opening, eliminates the frictional resistance of fractured rock particle to drilling rod.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further to specify.
Fig. 1 is the utility model front view;
Fig. 2 is a B-B sectional view among Fig. 1;
Fig. 3 is an A-A cutaway view Amplified image among Fig. 1;
Among the figure: 1-drilling rod body, 2-sleeve pipe, 3-member, 4-deslagging otch.
The specific embodiment
Embodiment one:
Like Fig. 1, drilling rod shown in Figure 2, comprise drilling rod body 1, said drilling rod body 1 periphery is provided with sleeve pipe 2, and said sleeve pipe 2 is fixing through member 3 welding with drilling rod body 1, and sleeve pipe 2 is the steel round tube; Be respectively equipped with two vertical deslagging otch 4 on the said sleeve pipe 2 periphery halves lines, said deslagging otch 4 is rectangles wide 2 centimetres, long 20 centimetres.
Embodiment two:
Drilling rod as shown in Figure 3 comprises drilling rod body 1, and said drilling rod body 1 periphery is provided with sleeve pipe 2, and said sleeve pipe 2 is fixing through member 3 welding with drilling rod body 1, and sleeve pipe 2 is the steel round tube; Be respectively equipped with two vertical deslagging otch 4 on the said sleeve pipe 2 periphery halves lines, said deslagging otch 4 is rectangles wide 5 centimetres, long 40 centimetres.
During use, drilling rod need to be fixedly connected with drill bit the rear can be used for preventing and treating coal and the outstanding boring of gas with gas pumping, prevent harnessing the river, construction that geological survey is holed.
Drilling rod body periphery is equipped with circular steel sleeve pipe, and sleeve pipe adopts the member of special substance to be fixedly connected through welding manner with the drilling rod body, and the external surface of sleeve pipe adopts special process to polish smooth, and makes sleeve pipe resistance in rotary course keep minimum.When holing, hole with drill bit in the place of regulation, the sleeve pipe of drilling rod body periphery is located drilling tool, prevents that drill bit from producing skew, lets boring keep the design straight path, solves the hole scattering problem.Drilling rod is when the boring rotation, and ground grains gets in the gap between drilling-rod external wall and the sleeve pipe, then can discharge from the deslagging otch, eliminates the frictional resistance of fractured rock particle to drilling rod.So the drilling rod body periphery of the utility model is established sleeve pipe, make drilling rod be prone to the location, bushing outer surface has carried out polishing to be handled, and has reduced frictional force, accelerates the efficient of boring; Bushing outer surface is provided with slag-drip opening, eliminates the frictional resistance of fractured rock particle to drilling rod.
So the utility model has realized holing preferably effect, guarantee that boring measures such as mine protrusion-dispelling or gas exhaust implement completely, ensure Safety of Coal Mine Production.
The foregoing description is not limited only to the protection domain of the utility model, all based on the basic thought of the utility model and make amendment or the protection domain that all belongs to the utility model that changes in.
