Compared with existing drill steel, aluminium drill pipe has outstanding advantage in deadweight, specific strength, elasticity and corrosion resistance etc.; Aluminium drill pipe also has weak point simultaneously, aluminium alloys body of rod hardness is low, wear no resistance, as hole wall has hard foreign matter, hole deviation, surface very easily produces Fast Wearing, have a strong impact on the quality of aluminium drill pipe at the bottom of hole, add accident rate at the bottom of hole, especially aluminium drill pipe this problem in deep hole and superdeep holes probing is badly in need of solving.
Summary of the invention
The technical problems to be solved in the utility model is for the deficiencies in the prior art, and proposing a kind of increases drilling rod wear-resistant, improves drilling life of drill pipe, and the two ends that can reduce costs thicken Double layer rope cable and to core aluminium drill pipe.
The technical problems to be solved in the utility model is achieved through the following technical solutions, a kind of two ends thicken Double layer rope cable and to core aluminium drill pipe, be characterized in: comprise aluminium drill pipe body, one end of aluminium drill pipe body is connected with public steel joint by external screw thread I, the other end of aluminium drill pipe body is connected with female steel joint by external screw thread II, aluminium drill pipe body outer wall between external screw thread I root and external screw thread II root is enclosed with stainless steel wear-resistant sleeve, the basic unit that bonds is provided with between stainless steel wear-resistant sleeve and aluminium drill pipe body, the external diameter of described stainless steel wear-resistant sleeve is with public, the external diameter of female steel joint is identical, inside, described aluminium drill pipe body two ends is respectively arranged with increases external screw thread I, the thickened area of II wall thickness, thickened area connects with the interior walls be smooth of aluminium drill pipe body.
The technical problems to be solved in the utility model can also be come to realize further by the following technical programs, the internal diameter of described male and female steel joint and the identical setting of internal diameter of aluminium drill pipe body thickened area.
The technical problems to be solved in the utility model can also be come to realize further by the following technical programs, and the thickness of described stainless steel wear-resistant sleeve is 0.8mm-1mm.
The technical problems to be solved in the utility model can also be come to realize further by the following technical programs, the middle part internal diameter 1mm-3mm larger than thickened area, two ends internal diameter of described aluminium drill pipe body.
The technical problems to be solved in the utility model can also be come to realize further by the following technical programs, described public steel joint is provided with pin thread away from one end of aluminium drill pipe body, female steel joint is provided with the box coordinated with pin thread, and the pin thread of male steel joint and the box of female steel joint adopt the overhead kick button screw thread cooperatively interacted.
Compared with prior art, the utility model utilizes the stainless steel wear-resistant sleeve be wrapped on aluminium drill pipe body outer wall, effectively raise the abrasion resistance of aluminium drill pipe body, solve the problem that aluminium drill pipe wears no resistance, decrease accident at the bottom of the hole caused because of aluminium drill pipe serious wear, improve the application life of drill string, reduce construction cost; Utilize the thickened area being arranged on inside, aluminium drill pipe body two ends, add the wall thickness of thread root, effectively enhance the intensity and reliability that are threaded.The utility model enhances the abrasion resistance of aluminium drill pipe external surface while increasing screw thread tension, torsional strength, solve the problem that aluminium drill pipe external surface hardness is low, wear no resistance, for wire line coring aluminium drill pipe to provide the foundation guarantee in the application of deep hole and superdeep holes drilling field.
