A kind of engineering driller drilling rod
Technical field
The utility model relates to rig aid technical field, particularly a kind of engineering driller drilling rod.
Background technology
In boring procedure, because of combined stresseses such as drilling rod bears shearing simultaneously, reverses, pressurizes, frictions, drilling rod is easier to wearing and tearing and scraps, so the reasonability of the used making material of drilling rod and manufacture craft and structure design, to the resisting breakage ability of drilling rod, balance, shock resistance all have a significant impact, if the making of drilling rod and jackrod structure can improve according to actual working environment, can not only reduce cost of manufacture, increase work efficiency, also can prolong drilling life of drill pipe.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of engineering driller drilling rod, reasonable in design, intensity height, long service life.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of engineering driller drilling rod is provided, comprise tube connector, described tube connector two ends are furnished with upper flange I and lower flange II respectively, be furnished with several reinforcing ribs between described tube connector and upper flange I and the lower flange II, be furnished with several connecting holes on the flange face of described upper flange I and lower flange II, be furnished with ventilating pipe between described upper flange I and the lower flange II, described ventilating pipe outer surface cloth is equipped with protective cover, connects by union between the described ventilating pipe.
Be furnished with connecting pin on the described upper flange I.
Described lower flange II is connected with drill bit by connecting hole.
Beneficial effect
The utility model relates to a kind of engineering driller drilling rod, reasonable in design, and total is designed to revolving body, and work balance height is furnished with reinforcing rib, and shock resistance is good, intensity height, long service life.
