Abstract
The utility model provides a drilling rod that is arranged in fan blade bolt to take out equipment, the drilling rod body constitutes by the drilling rod link and rather than the drilling rod body that is connected, and the length an of drilling rod body is 41cm, and the length a` of drilling rod link is 8cm, and the length a`` of drilling rod body is 33cm. The utility model discloses the length of drilling rod has been increased to during the thread end that makes the drill bit can arrive fan blade's bolt, thereby make the drilling rod under the drive of power supply, take out the bolt in by fan blade, owing to increased the length of drilling rod link, consequently, increased the area of contact between drilling rod and the power supply, avoid the drilling rod in the power supply under operating condition, by breaking away from.
Description
Technical field
The utility model relates to a kind of drilling rod, especially a kind of for the drilling rod in fan blade bolt extraction device.
Background technology
Because the thickness of fan blade is very large, and existing drilling rod on fit on drill bit after, its length is still less than the thickness of fan blade, therefore, adopts the existing drilling rod being equipped with drill bit the bolt in fan blade cannot be taken out.
Summary of the invention
For the weak point existed in the problems referred to above, the utility model provides a kind of end of thread of drill bit that enables to arrive in the bolt of fan blade, thus make drilling rod under the driving of power source, by bolt by the drilling rod be used in fan blade bolt extraction device taken out in fan blade.
For achieving the above object, the utility model provides a kind of for the drilling rod in fan blade bolt extraction device, drilling rod body (1) is made up of drilling rod link (2) and coupled drill pipe body (3), the length (a) of described drilling rod body (1) is 41cm, the length (a`) of described drilling rod link (2) is 8cm, and the length (a``) of described drill pipe body (3) is 33cm.
Above-mentioned for the drilling rod in fan blade bolt extraction device, wherein, described drill pipe body (3) establishes region (32) to form by upper area (31) and drill chuck, and the inside of described upper area (31) is solid construction.
Above-mentioned for the drilling rod in fan blade bolt extraction device, wherein, described drill chuck establishes the diameter in region (32) to be less than the diameter of described upper area (31).
Above-mentioned for the drilling rod in fan blade bolt extraction device, wherein, the diameter of described upper area (31) is 32mm, and described drill chuck sets the diameter in region as 31mm.
Above-mentioned for the drilling rod in fan blade bolt extraction device, wherein, described drill chuck sets region (32) to be formed as the port (4) of described drill pipe body (3) extends 15cm to its other end.
Compared with prior art, the utility model has the following advantages:
The utility model adds the length of drilling rod, thus the end of thread of drill bit is arrived in the bolt of fan blade, thus makes drilling rod under the driving of power source, is taken out by bolt by fan blade;
Owing to adding the length of drilling rod link, therefore, add the contact area between drilling rod and power source, under avoiding drilling rod in working order, depart from by power source;
Due to the upper area of drill pipe body is set to solid construction, therefore, the intensity of drilling rod entirety can be strengthened.
Accompanying drawing explanation
Fig. 1 is structure chart of the present utility model.
Main Reference Numerals is described as follows:
1-drilling rod body 2-drilling rod link 3-drill pipe body
31-upper area 32-drill chuck establishes region 4-port
Detailed description of the invention
As shown in Figure 1, the drilling rod body 1 that the utility model provides is made up of drilling rod link 2 and coupled drill pipe body 3, and the length a of drilling rod body 1 is 41cm, and the length a` of drilling rod link 2 is 8cm, and the length a`` of drill pipe body 3 is 33cm.The lateral cross section of drill pipe body 3 is cylindrical structural, and drilling rod link 2 is arranged on the home position of drill pipe body 3.Wherein, drilling rod link 2 and drill pipe body 3 are integral type structure.
Drill pipe body 3 establishes region 32 to form by upper area 31 and drill chuck, and drill chuck establishes the diameter in region 32 to be less than the diameter of upper area 31.
Drill chuck sets the inside in region 32 as hollow form structure, and its bottom end face is upwards extended to drill pipe body 3 other end by the port 4 of drill pipe body 3, establishes region 32 to form the drill chuck that length a``` is 15cm.
Wherein, port 4 is unenclosed construction, and the top of drill bit is arranged on through port 4 inside that drill chuck establishes region 32.
In the present embodiment, the diameter of upper area 31 is 32mm, and drill chuck sets the diameter in region as 31mm.
Owing to being solid construction by the indoor design of upper area, therefore, the intensity of drill pipe body can be increased.
The foregoing is only preferred embodiment of the present utility model, is only illustrative for invention, and nonrestrictive.Those skilled in the art is understood, and can carry out many changes in the spirit and scope that invention claim limits to it, amendment, even equivalence, but all will fall in protection domain of the present utility model.
