Abstract

The utility model relates to the technical field of drilling machines, particularly to a drill rod special for a turning drilling machine. The drill rod special for the turning drilling machine comprises a drill rod body which adopts a hollow structure, wherein a taper thread for being connected with a drill is arranged at one end of the drill rod body, and a common metric system thread for being connected with the drilling machine is arranged at the other end of the drill rod body. The drill rod special for the turning drilling machine has the benefits of low manufacturing cost, long service life and wide usage occasion.

Description

Turning rig drill rod special
Technical field
The utility model relates to the drilling rig technique field, relates in particular to a kind of turning rig drill rod special.
Background technology
Pneumatic drilling vehicle is mostly adopted in the explosion of the modern cubic metre of earth and stone, and is furnished with the extension bar drilling rod and impactor is being holed on rock or on sandstone, and the extension bar drilling rod that wherein adopts and impactor are its main bore operation instruments.
The operating principle of above-mentioned pneumatic drilling vehicle is: the pneumatic rotary motor driving drilling rod on the rig drill boom is rotated motion, the impactor piston that is disposed on drilling rod hits drill bit, and then rock-breaking drilling, the propulsion motor promotion drilling rod of drill boom rear end and impactor deepen continuously at the bottom of the hole, the rock slag of gases at high pressure at the bottom of with the hole blows out, to reach the purpose of boring.
But the link of extension bar drilling rod of above-mentioned rig own is the special screw thread structure, during processing and manufacturing, cost is relatively high, the rig use cost that adopts above-mentioned drilling rod to be used in conjunction with is also high: a machine needs 2 people's operations, independent air compressor plant must be arranged, therefore above-mentioned drilling rod is high with the rig whole use cost that is used in conjunction with, inconvenient operation.
The utility model content
The purpose of this utility model is to provide a kind of turning rig drill rod special, to solve the high technical problem of existing borer drill rod processing and manufacturing cost.
The utility model is achieved in that a kind of turning rig drill rod special, comprises the drilling rod body, and described drilling rod body is hollow-core construction, and described drilling rod body one end is provided with for the taper thread that connects drill bit, and the other end is provided with for the metric system regular screw threads that connect rig.
As improving further, the nominal diameter of described drilling rod body is 50mm, and described metric system regular screw threads are M45 * 4.5.
As improving further, described drilling rod body is the drilling rod body that bainitic steel is made.
After having adopted technique scheme, the beneficial effects of the utility model are:
Because an end processing and manufacturing of drilling rod becomes the regular screw threads structure, can coordinate the one man operation and use on the turning rig of low cost of manufacture, thereby having reduced the manufacturing cost of whole use, the processing cost of drilling rod itself is also low simultaneously, have good economic use value, use easy to operate.
Process because material adopts the LV710 bainitic steel to carry out normalizing and tempering, the surface has higher hardness, and tensile strength is large simultaneously, is difficult for bending or fracture, and application life is longer, is widely used in general earthwork explosion, has improved functional performance.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
In figure: 1, drilling rod body, 2, metric system regular screw threads, 3, taper thread.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
As shown in Figure 1, a kind of turning rig drill rod special comprises drilling rod body 1, and this drilling rod body 1 is hollow-core construction, and drilling rod body 1 one ends are provided with for the taper thread 3 that connects drill bit, and the other end is provided with for the metric system regular screw threads 2 that connect rig.
The nominal diameter of drilling rod body 1 is 50mm, and metric system regular screw threads 2 are M45 * 4.5.
The drilling rod body that drilling rod body 1 is made for bainitic steel.
The utility model in use, at first adopting diameter is 50 millimeters of φ, length is the drilling rod body 1 of 3.66 meters, and an end of drilling rod body 1 is processed into the metric system regular screw threads 2 that screw thread is M45 * 4.5, the other end is processed as the taper thread 3 of φ 34-9 °, pitch is 5.08mm;
Drilling rod body 1 integral material adopts the LV710 bainitic steel, and after processing by the tempering process of the best, obtainable mechanical property is: tensile strength 1450.9MPa, hardness 39.7HRC, impact toughness 49.8J.
This drilling rod body 1 mainly fits over the lower turning rig of use cost, is used for substituting some pneumatic drilling vehicle drilling rod operations, and the manufacturing cost of drilling rod own is lower, and application life is longer, is widely used in general earthwork explosion, has good economic benefit.
A kind of turning rig drill rod special that the utility model provides, because drilling rod one end is processed as regular screw threads, make the low cost of manufacture of drilling rod own, owing to having adopted the bainitic steel section bar, by having improved after temper the application life of drilling rod, improved whole functional performance.
The above is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
