Description

A kind of bushing type drilling rod
Technical field
The present invention relates to mechanical field, especially relate to a kind of bushing type drilling rod, the present invention is number of patent application " 2013103283277 ", the divisional application of the Chinese patent application that name is called " a kind of rotary drilling rig ".
Background technology
Rotary drilling rig is also known as " rotary bucket rig ", and A Siteli rig etc. are a kind of heavy caliber deep hole pore-forming equipments.Because adopt " rotary bucket " or be called that " rotary bucket " telescopic drill rod adopting square or circle to add sword that fetches earth strengthens drilling depth, so be called as " rotary drilling rig " or be called " rotary bucket rig " simultaneously.Modal rotary drilling rig has two kinds: one to be the attaching converted with crawler crane at the construction field (site) at present, and another kind introduces imitated likeness in form chassis of dredging machine by state's external structure completely to reequip the full hydraulic being adjusted drilling rod verticality by trapezoidal linkage and hydraulic cylinder acting in conjunction.Full hydraulic develops rapidly in recent years, has eliminated the crawler crane attaching that heavier efficiency is lower slightly gradually, becomes the representative type of rotary drilling rig, revolves one of the method for digging main hole forming method also becoming heavy caliber deep hole.When traditional use rotary drilling rig is driven piles, drive all parts by motor, drill bit is guided by the wire rope on winch, is subject to driving rear leaning on from gravity downfeed.Therefore, there is many defects in traditional rig that digs: one, the deadweight of drill bit is not enough, if when running into hard earth, not enough to the power pressed down; Two, the helical blade on drill bit is longer, and when digging to backspin, the frictional force be subject to is large, and the power that complete machine is consumed is large; Three, unit head is heavy, the mode of being pressurizeed by Direct driver, and drilling rod can be made stressed comparatively large, and therefore the power output of winch is large, the big energy-consuming of complete machine.
The patent No. is that CN 20092024625.4 discloses a kind of hydraulic rotatory drilling-rig, it comprises crawler attachment, get on the bus in the chassis be positioned on crawler attachment, driver's cabin, be arranged on chassis get on the bus on column, be arranged on the unit head on column, the drilling rod driven by unit head, be arranged on the drill bit of drill rod end, and the first drive unit, on getting on the bus in chassis, be provided with the second drive unit and the electric control gear for controlling the first drive unit and the second drive unit.Electric power between the first drive unit and the second drive unit and fuel power conversion can be realized by electric control gear.Although this utility model can change electric power and fuel power, different duty requirements can be met to a certain extent, improve the practicality of rotary drilling rig, but still it is large to there is rotary drilling rig build, consumes energy high, complex structure, the problem that cost is high.
And, be all the independent drilling rod of integration at present at the drilling rod of stake work field application, drilling rod design how long, how dark just can only bore when piling or bore operation, the drilling rod of deep hole operation is long, cause whole device length very large, the material expended, and the equal geometric growth of the energy consumed, high cost, limit its application, and when less field construction or mountain construction, the equipment of large volume is also unfavorable for transport and action.
